     MESSAGE FROM THE PRESIDENT AND SEMIANNUAL REPORT

     Unaudited - April 30, 2010

     MainStay 130/30 Core Fund
     MainStay 130/30 Growth Fund
     MainStay 130/30 International Fund



MESSAGE FROM THE PRESIDENT

During the six months ended April 30, 2010, stock and bond markets generally
advanced, despite some volatility in January and February. Domestic small-cap
stocks were particularly strong, and U.S. stocks at all capitalization levels
provided double digit returns. Value stocks outpaced growth stocks for companies
of all sizes during the reporting period.

International stocks provided positive returns overall, but results varied
widely by country. Concerns about Greece's ability to meet its debt obligations
led many investors to abandon their holdings in Greece and question their
investments in several peripheral European nations where perceived risk had
increased. For the six-month reporting period, equities in the Far East
(including Japan) tended to be stronger than those in Europe.

The economic recovery in the United States continued. Real gross domestic
product advanced in the first quarter of 2010, though at a slower pace than in
the fourth quarter of 2009. The Federal Open Market Committee kept the targeted
federal funds rate at a historically low level throughout the reporting period,
which prompted many investors to leave the safety of U.S. Treasury securities in
search of higher yield.

In the high-yield bond market, lower-rated credits tended to be the strongest
performers. With investment-grade investors crossing into high-yield territory,
however, the highest-rated high-yield credits also saw strong demand. In the
municipal market, new-issue supply was reduced by government incentives that
encouraged municipal issuers to raise funds in the taxable market. In the
leveraged-loan market, new issuance strengthened, but extensive repayments
caused the market as a whole to contract.


Throughout the six-month reporting period, MainStay's portfolio managers sought
to make the most of market conditions within the investment strategies and risk
parameters of their respective Funds. While individual markets and Fund results
may vary, our pursuit of competitive returns over full market cycles has never
changed.

The information that follows provides a closer look
at the securities, strategies and market conditions that affected your MainStay
Fund(s) during the six months ended April 30, 2010. Of course, past performance
is no guarantee of future results. Even in a rising market, we believe that
maintaining a long-term perspective can be valuable. At MainStay, we believe
that in all markets, broad diversification, gradual allocation adjustments and
regular portfolio reviews can help guide you toward your long-range financial
goals.

We thank you for choosing MainStay Funds, and we look forward to serving your
investment needs for many years to come.

Sincerely,

/s/ STEPHEN P. FISHER

Stephen P. Fisher
President

1. Performance tables and graphs do not reflect the deduction of taxes that a
   shareholder would pay on distributions or Fund-share redemptions. Total
   returns reflect maximum applicable sales charges explained in this paragraph,
   change in share price, and reinvestment of dividend and capital gain
   distributions. The graphs assume an initial investment of $25,000 for Class A
   shares and $10,000 for all other classes and reflect the deduction of all
   sales charges that would have applied for the period of investment. Class A
   shares generally have a $25,000 minimum initial investment with no minimum

   of $100,000 or more invested in any share classes of any of the MainStay
   Funds, the minimum initial investment is $15,000. Investor Class shares and
   Class A shares are sold with a maximum initial sales charge of 5.50% and an
   annual 12b-1 fee of 0.25%. Class C shares are sold with no initial sales
   charge, are subject to a contingent deferred sales charge ("CDSC") of 1.00%
   if redeemed within one year of purchase, and have an annual 12b-1 fee of
   1.00%. Class I shares are sold with no initial sales charge or CDSC, have no
   annual 12b-1 fee, and are generally available to corporate and institutional
   investors or individual investors with a minimum initial investment of $5

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY 130/30 CORE FUND (UNAUDITED)
- --------------------------------------------------------------------------------

The example below is intended to describe the fees and expenses borne by
shareholders during the six-month period from November 1, 2009, to April 30,
2010, and the impact of those costs on your investment.

EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, exchange fees, and sales charges (loads) on
purchases (as applicable), and (2) ongoing costs, including management fees,
distribution and/or service (12b-1) fees, and other Fund expenses (as
applicable). This example is intended to help you understand your ongoing costs
(in dollars) of investing in the Fund and to compare these costs with the
ongoing costs of investing in other mutual funds. The example is based on an
investment of $1,000 made at the beginning of the six-month period and held for
the entire period from November 1, 2009, to April 30, 2010.

This example illustrates your Fund's ongoing costs in two ways:

- - ACTUAL EXPENSES
The second and third data columns in the table below provide information about
actual account values and actual expenses. You may use the information in these
columns, together with the amount you invested, to estimate the expenses that
you paid during the six-months ended April 30, 2010. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number under the heading entitled "Expenses Paid
During Period" to estimate the expenses you paid on your account during this
period.

- - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The fourth and fifth data columns in the table below provide information about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense ratio and an assumed rate of return of 5% per year before expenses,
which is not the Fund's actual return. The hypothetical account values and
expenses may not be used to estimate the actual ending account balances or
expenses you paid for the six-month period shown. You may use this information
to compare the ongoing costs of investing in the Fund with the ongoing costs of
investing in other Funds. To do so, compare this 5% hypothetical example with
the 5% hypothetical examples that appear in the shareholder reports of the other
Funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as
redemption fees, if applicable, exchange fees, or sales charges (loads).
Therefore, the fourth and fifth data columns of the table are useful in
comparing ongoing costs only and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.

8    MainStay 130/30 Core Fund



PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

QUESTIONS ANSWERED BY PORTFOLIO MANAGERS HARVEY J. FRAM, CFA, AND MONA PATNI OF
MADISON SQUARE INVESTORS LLC, THE FUND'S SUBADVISOR.


HOW DID MAINSTAY 130/30 CORE FUND PERFORM RELATIVE TO ITS PEERS AND ITS
BENCHMARK DURING THE SIX MONTHS ENDED APRIL 30, 2010?

Excluding all sales charges, MainStay 130/30 Core Fund returned 13.10% for
Investor Class shares, 13.37% for Class A shares and 12.70% for Class C shares
for the six months ended April 30, 2010. Over the same period, Class I shares
returned 13.44%. All share classes underperformed the 13.97% return of the
average Lipper(1) extended U.S. large-cap core fund and the 16.77% return of the
Russell 1000(R) Index(2) for the six months ended April 30, 2010. The Russell
1000(R) Index is the Fund's broad-based securities-market index. See page 5 for
Fund returns with sales charges.

WHAT FACTORS WERE RESPONSIBLE FOR THE FUND'S RELATIVE PERFORMANCE DURING THE
REPORTING PERIOD?

For the six months ended April 30, 2010, the Fund underperformed the Russell
1000(R) Index primarily because it emphasized high-quality stocks in a period
when the market, especially in the financials sector, rewarded low-quality
stocks (stocks with low or negative earnings).

DURING THE REPORTING PERIOD, WHICH SECTORS WERE THE STRONGEST CONTRIBUTORS TO
THE FUND'S RELATIVE PERFORMANCE AND WHICH SECTORS DETRACTED THE MOST?

During the reporting period, the Fund's top-contributing sectors relative to the
Russell 1000(R) Index were consumer staples, materials and utilities.
Underweight Fund positions in the consumer staples and utilities sectors were
beneficial, as these sectors, which typically are not economically sensitive,
underperformed the Index. Despite the conservative nature of these sectors, an
overweight position in meat products company Tyson Foods (in the consumer
staples sector) enhanced the Fund's relative performance, as the company's stock
gained more than 50% during the reporting period. In the materials sector, an
overweight position in chemical producer Ashland contributed positively to the
Fund's relative performance.

The most significant sector detractors relative to the Russell 1000(R) Index
included financials, information technology and health care. In a market that
generally preferred lower-quality stocks, the Fund's bias toward high-quality
stocks hurt relative performance. During the reporting period, short positions
in financial companies MBIA and Zions Bancorp and a long (but underweight)
position in Citigroup--all companies with negative or low earnings--outperformed
such blue chip companies as JP Morgan Chase and Travelers. In addition, the
market's concerns about new health care legislation caused a number of the
Fund's overweight positions in health care services stocks to underperform the
Index. One notable example was Aetna.

DURING THE REPORTING PERIOD, WHICH STOCKS
WERE THE STRONGEST CONTRIBUTORS TO THE FUND'S ABSOLUTE PERFORMANCE AND WHICH
STOCKS WERE PARTICULARLY WEAK?

In absolute terms, the stocks that made the greatest positive contributions to
the Fund's performance were computers & peripherals company Apple, industrial
conglomerate General Electric and chemicals company Ashland. All three stocks
advanced significantly during the reporting period, led by Apple, which
continues to gain market share with the iPhone. Apple also benefited from the
introduction of the iPad. General Electric and Ashland performed well as the
economy rebounded.

Significant detractors from absolute performance included insurer MBIA, health
maintenance organization Health Net and insurance company Old Republic
International. All three were short positions in the Fund but had strong
positive returns during the reporting period. We think that the prospects at
MBIA and Old Republic improved dramatically with a stronger economic outlook.
While new health care legis-
lation hurt many health care stocks, Health Net ad- vanced on the perception
that new legislation would
have less adverse effects on the company than pre-viously anticipated.

DID THE FUND MAKE ANY SIGNIFICANT PURCHASES OR SALES DURING THE REPORTING
PERIOD?

During the reporting period, the Fund initiated a position in semiconductor
company Intel. Given the continued build-out of computer networks and smart
mobile devices, we purchased Intel as a conservative way to participate in this
trend. Intel had high earnings quality and benefited from positive reactions by
analysts to the company's earnings announcements.

During the reporting period, the Fund sold its positions in financial service
company Bank of New York Mellon and aerospace & defense company Lockheed Martin.
Bank of New York Mellon is a conservatively

run bank that had become expensive according to our valuation measures. In its
place, we purchased Bank of America, which our model deemed to be undervalued
and well positioned to benefit from a recovery in the U.S. economy. Lockheed
Martin was sold as most of our technical indicators on the stock turned
negative, as did our earnings-quality measure. We also sold a large part of the
Fund's position in ExxonMobil after the announcement of its pending merger with
XTO Energy. ExxonMobil's stock seemed expensive relative to others in the same
industry, and market sentiment about ExxonMobil has been negative in the wake of
the XTO Energy deal.

HOW DID THE FUND'S WEIGHTINGS CHANGE RELATIVE TO THE RUSSELL 1000(R) INDEX
DURING THE REPORTING PERIOD?

During the reporting period, we increased the Fund's exposure to the health care
and consumer staples sectors. In health care, we purchased pharmaceutical
companies (such as Abbot Laboratories) and service providers (such as Cardinal
Health) that we believed had become undervalued in the wake of the new health
care legislation. In consumer staples, we purchased stocks such as food products
company Conagra Foods and food & staples retailer Costco Wholesale, but the Fund
overall maintained an underweight position in the sector.

Relative to the Russell 1000(R) Index, the Fund reduced its exposure to the
energy and information technology sectors. Energy stocks advanced as the price
of oil rose during the reporting period, but many have exposure to natural gas,
which dropped dramatically in price. As a result, a number of energy stocks have
higher-than-average valuations. We also reduced the Fund's position in
ExxonMobil, as described above. Although we reduced the Fund's exposure to
information technology, the Fund remains overweight relative to the Index in
this sector. The weighting reduction in information technology was primarily a
risk-management decision.

HOW WAS THE FUND POSITIONED AT THE END OF APRIL 2010, AND HOW DID THIS
POSITIONING AFFECT THE FUND'S PERFORMANCE?

As of April 30, 2010, the most substantially overweight sectors in the Fund
relative to the Russell 1000(R) Index were consumer discretionary and
information technology. In the consumer discretionary sector, retailers used
tight inventory controls to beat profit expectations despite lackluster sales.
Our overweight position in information technology detracted from the Fund's
results because the sector underperformed the Index despite generally strong
earnings.

On the same date, the Fund's most substantially underweight sectors relative to
the Russell 1000(R) Index were financials and utilities. Within financials, as
in the Fund as a whole, we tended to avoid companies with low or negative
earnings ratios. This positioning hurt performance as investors sought to
benefit from companies with lower quality profiles. From an industry
perspective, the Fund was underweight real estate investment trusts (REITs) and
regional banks at the end of the reporting period but overweight insurance
companies. Utilities are typically a low-risk sector, and our underweight
position helped the Fund on a relative basis, as utilities lagged the Index as a
whole.

this report and are subject to change. There is no guarantee that any forecasts

1. Performance tables and graphs do not reflect the deduction of taxes that a
   shareholder would pay on distributions or Fund-share redemptions. Total
   returns reflect maximum applicable sales charges explained in this paragraph,
   change in share price, and reinvestment of dividend and capital gain
   distributions. The graphs assume an initial investment of $25,000 for Class A
   shares and $10,000 for all other classes and reflect the deduction of all
   sales charges that would have applied for the period of investment. Class A
   shares generally have a $25,000 minimum initial investment with no minimum
   subsequent purchase amount. For investors that, in the aggregate, have assets
   of $100,000 or more invested in any share classes of any of the Mainstay
   Funds, the minimum initial investment is $15,000. Investor Class shares and
   Class A shares are sold with a maximum initial sales charge of 5.50% and an
   annual 12b-1 fee of 0.25%. Class C shares are sold with no initial sales
   charge, are subject to a contingent deferred sales charge ("CDSC") of 1.00%
   if redeemed within one year of purchase, and have an annual 12b-1 fee of
   1.00%. Class I shares are sold with no initial sales charge or CDSC, have no
   annual 12b-1 fee, and are generally available to corporate and institutional
   investors or individual investors with a minimum initial investment of $5
   million. Performance figures reflect certain fee waivers and/or expense
   limitations, without which total returns may have been lower. For information
   on current fee waivers and/or expense limitations, please refer to the notes
   to the financial statements.

3. The Russell 1000(R) Growth Index measures the performance of those Russell
   1000(R) companies with higher price-to-book ratios and higher forecasted
   growth values. The Russell 1000(R) Index measures the performance of the
   1,000 largest companies in the Russell 3000(R) Index, which represents
   approximately 92% of the total market capitalization of the Russell 3000(R)
   Index. The Russell 3000(R) Index measures the performance of the 3,000
   largest U.S. companies based on total market capitalization, which represents
   approximately 98% of the investable U.S. equity market. Total returns assume
   reinvestment of all dividends and capital gains. The Russell 1000(R) Growth
   Index is the Fund's broad-based securities market index for comparison
   purposes. An investment cannot be made directly in an index.

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY 130/30 GROWTH FUND
(UNAUDITED)
- --------------------------------------------------------------------------------

The example below is intended to describe the fees and expenses borne by
shareholders during the six-month period from November 1, 2009, to April 30,
2010, and the impact of those costs on your investment.

EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, exchange fees, and sales charges (loads) on
purchases (as applicable), and (2) ongoing costs, including management fees,
distribution and/or service (12b-1) fees, and other Fund expenses (as
applicable). This example is intended to help you understand your ongoing costs
(in dollars) of investing in the Fund and to compare these costs with the
ongoing costs of investing in other mutual funds. The example is based on an
investment of $1,000 made at the beginning of the six-month period and held for
the entire period from November 1, 2009, to April 30, 2010.

This example illustrates your Fund's ongoing costs in two ways:

- - ACTUAL EXPENSES

The second and third data columns in the table below provide information about
actual account values and actual expenses. You may use the information in these
columns, together with the amount you invested, to estimate the expenses that
you paid during the six-months ended April 30, 2010. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number under the heading entitled "Expenses Paid
During Period" to estimate the expenses you paid on your account during this
period.

- - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The fourth and fifth data columns in the table below provide information about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense ratio and an assumed rate of return of 5% per year before expenses,
which is not the Fund's actual return. The hypothetical account values and
expenses may not be used to estimate the actual ending account balances or
expenses you paid for the six-month period shown. You may use this information
to compare the ongoing costs of investing in the Fund with the ongoing costs of
investing in other Funds. To do so, compare this 5% hypothetical example with
the 5% hypothetical examples that appear in the shareholder reports of the other
Funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as
redemption fees, if applicable, exchange fees, or sales charges (loads).
Therefore, the fourth and fifth data columns of the table are useful in
comparing ongoing costs only and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.

   (2.56% for Investor Class, 2.45% for Class A, 3.30% for Class C and 2.24% for
   Class I) multiplied by the average account value over the period, divided by
   365 and multiplied by 181 (to reflect the one-half year period). The table
   above represents the actual expenses incurred during the one-half year
   period.

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

QUESTIONS ANSWERED BY PORTFOLIO MANAGER HARISH KUMAR, PHD, CFA, OF MADISON
SQUARE INVESTORS LLC, THE FUND'S SUBADVISOR.

HOW DID MAINSTAY 130/30 GROWTH FUND PERFORM RELATIVE TO ITS PEERS AND ITS
BENCHMARK DURING THE SIX MONTHS ENDED APRIL 30, 2010?

Excluding all sales charges, MainStay 130/30 Growth Fund returned 6.74% for
Investor Class shares, 6.74% for Class A shares and 6.32% for Class C shares for
the six months ended April 30, 2010. Over the same period, the Fund's Class I
shares returned 6.82%. With the exception of Class C shares, all share classes
out-performed the 6.45% return of the average Lipper(1) long/short equity fund
for the six months ended April 30, 2010. All share classes underperformed the
15.79% return of the Russell 1000(R) Growth Index(2) over the same period. The
Russell 1000(R) Growth Index is the Fund's broad-based securities-market index.
See page 27 for Fund returns with sales charges.

WHAT FACTORS WERE RESPONSIBLE FOR THE FUND'S RELATIVE PERFORMANCE DURING THE
REPORTING PERIOD?

The Fund underperformed the Russell 1000(R) Growth Index primarily because of
stock selection in the health care and consumer staples sectors. An over-weight
position in health care and an underweight position in consumer staples also
detracted from the Fund's relative performance.

DURING THE REPORTING PERIOD, WHICH INDUSTRIES WERE THE STRONGEST CONTRIBUTORS TO
THE FUND'S ABSOLUTE PERFORMANCE AND WHICH INDUSTRIES WERE PARTICULARLY WEAK?

On an absolute basis, the strongest-contributing industries to the Fund's
performance were computers & peripherals, software and machinery. The weakest
industry contributions on an absolute basis came from food & staples retailing,
multiline retail and life sciences tools & services.


DURING THE REPORTING PERIOD, WHICH STOCKS WERE THE FUND'S STRONGEST PERFORMERS
AND WHICH STOCKS WERE PARTICULARLY WEAK?

On an absolute basis, the strongest contributors to the Fund's performance were
computers & peripherals company Apple, railroad operator Union Pacific and
software company Oracle. Major detractors from the Fund's absolute performance
included pharmaceutical retailer CVS Caremark and communications equipment
company Qualcomm. Both stocks produced negative returns, and CVS Caremark was
sold during the reporting period. Although Qualcomm was a negative performer the
Fund continued to hold the stock. Shares of semiconductor company Novell
advanced during the reporting period, but since the Fund had sold the stock
short, the position detracted from the Fund's performance.

DID THE FUND MAKE ANY SIGNIFICANT PURCHASES OR SALES DURING THE REPORTING
PERIOD?

During the reporting period, the Fund initiated long positions in consumer
staples company Procter & Gamble and Internet company Yahoo! and short positions
in real estate development company St. Joe and office supply retailer Office
Depot. Significant sales during the reporting period included education and
training service company Apollo Group, grocery store operator Whole Foods
Market, biotechnology company Illumina and pharmaceutical retailer CVS Caremark.

HOW DID THE FUND'S INDUSTRY WEIGHTINGS CHANGE RELATIVE TO THE RUSSELL 1000(R)
GROWTH INDEX DURING THE REPORTING PERIOD?

During the reporting period, the Fund increased its weightings relative to the
Russell 1000(R) Growth Index in health care and materials. Over the same period,
the Fund decreased its weightings relative to the Index in consumer
discretionary and financials.

   Index.

                                                   mainstayinvestments.com    31



HOW WAS THE FUND POSITIONED AT THE END OF APRIL 2010, AND HOW DID THIS
POSITIONING AFFECT THE FUND'S PERFORMANCE?

As of April 30, 2010, the Fund was overweight relative to the Russell 1000(R)
Growth Index in energy and telecommunication services. This positioning
contributed positively to the Fund's performance relative to the benchmark. On
the same date, the Fund was underweight in materials and consumer staples. Both
of these positions hurt the Fund's relative performance.

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY 130/30 INTERNATIONAL FUND
(UNAUDITED)
- --------------------------------------------------------------------------------

The example below is intended to describe the fees and expenses borne by
shareholders during the six-month period from November 1, 2009, to April 30,
2010, and the impact of those costs on your investment.

EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, exchange fees, and sales charges (loads) on
purchases (as applicable), and (2) ongoing costs, including management fees,
distribution and/or service (12b-1) fees, and other Fund expenses (as
applicable). This example is intended to help you understand your ongoing costs
(in dollars) of investing in the Fund and to compare these costs with the
ongoing costs of investing in other mutual funds. The example is based on an
investment of $1,000 made at the beginning of the six-month period and held for
the entire period from November 1, 2009, to April 30, 2010.

This example illustrates your Fund's ongoing costs in two ways:

- - ACTUAL EXPENSES
The second and third data columns in the table below provide information about
actual account values and actual expenses. You may use the information in these
columns, together with the amount you invested, to estimate the expenses that
you paid during the six-months ended April 30, 2010. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number under the heading entitled "Expenses Paid
During Period" to estimate the expenses you paid on your account during this
period.

- - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The fourth and fifth data columns in the table below provide information about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense ratio and an assumed rate of return of 5% per year before expenses,
which is not the Fund's actual return. The hypothetical account values and
expenses may not be used to estimate the actual ending account balances or
expenses you paid for the six-month period shown. You may use this information
to compare the ongoing costs of investing in the Fund with the ongoing costs of
investing in other Funds. To do so, compare this 5% hypothetical example with
the 5% hypothetical examples that appear in the shareholder reports of the other
Funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as
redemption fees, if applicable, exchange fees, or sales charges (loads).
Therefore, the fourth and fifth data columns of the table are useful in
comparing ongoing costs only and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.



                                                                           ENDING ACCOUNT

for Investor Class shares, 1.89% for Class A shares and 1.63% for Class C shares
for the six months ended April 30, 2010. Over the same period, Class I shares
returned 2.08%. All share classes underperformed the 6.45% return of the average
Lipper(1) long/short equity fund and the 2.48% return of the Morgan Stanley
Capital International Europe, Australasia and Far East Index (the MSCI EAFE(R)
Index)(2) for the six months ended April 30, 2010. The MSCI EAFE(R) Index is the
Fund's broad-based securities market index. See page 44 for Fund returns with
sales charges.

WHAT FACTORS AFFECTED THE FUND'S RELATIVE PERFORMANCE DURING THE REPORTING
PERIOD?

The Fund underperformed the MSCI EAFE(R) Index during the reporting period.
Exposure to Greece and Spain detracted from the Fund's results. The Fund
initially held overweight positions in Greece, Spain and Portugal but moved to
underweight positions in each of these countries as concerns increased about
possible defaults of government-issued debt.

DURING THE REPORTING PERIOD, WHICH INDUSTRY GROUPS WERE THE STRONGEST
CONTRIBUTORS TO THE FUND'S RELATIVE PERFORMANCE AND WHICH INDUSTRY GROUPS WERE
PARTICULARLY WEAK?

During the reporting period, the industry groups that made the strongest
contributions to the Fund's performance relative to the MSCI EAFE(R) Index were
capital goods, media and technology hardware & equipment. From an industry group
perspective, the most significant detractors from the Fund's performance
relative to the MSCI EAFE(R) Index were banks and utilities (both of which
underperformed the Index) and retailing (which outperformed the Index). Although
the Fund was, on average, overweight among retailers, poor stock selection
caused the Fund's retail holdings to underperform industry-group-related stocks
in the benchmark.

WHICH COUNTRIES WERE THE STRONGEST CON-TRIBUTORS TO THE FUND'S RELATIVE
PERFORMANCE AND WHICH COUNTRIES WERE PARTICULARLY WEAK?

The weakest-contributing countries included Australia (where poor stock
selection caused the Fund to lag an otherwise outperforming country) and Spain
and Greece (which significantly underperformed the Index). The strongest-
contributing countries were Germany, Hong Kong and Italy, all of which
outperformed the Index.

DURING THE REPORTING PERIOD, WHICH INDIVIDUAL FUND HOLDINGS WERE STRONG
CONTRIBUTORS TO THE FUND'S ABSOLUTE PERFORMANCE AND WHICH HOLDINGS WERE WEAK?

On an absolute basis, the strongest contributors to the Fund's performance were
long positions in Norwegian oil field service company Acergy S.A., Australian
mining company BHP Billiton, Ltd., and British engineering solutions company IMI
PLC. In addition, short positions in the Austrian biotechnology company
Intercell A.G. and German pay-television provider Sky Deutschland A.G.
contributed positively to performance.

The Fund's weakest-contributing long positions included National Bank of Greece
S.A. and two Spanish commercial banks, Banco Santander S.A. and Banco Bilbao
Vizcaya Argentaria S.A. Short positions in Australian mining companies
Riversdale Mining LTD and Iluka Resources LTD detracted from performance.

DID THE FUND MAKE ANY SIGNIFICANT PURCHASES OR SALES DURING THE REPORTING
PERIOD?

In February 2010, we initiated positions in Japanese capacitor manufacturer
Nichicon and marine transport company Kawasaki Kisen Kaisha Ltd. We reduced the
Fund's positions in National Bank of Greece and Banco Santander in early
February 2010, in response to the escalating risk of default by Greece and the
potential effects elsewhere in Europe. During the reporting period, we
established short positions in German pay-television provider Sky Deutsch-
land A.G. and Danish biotechnology company Genmab A/S.

HOW DID THE FUND'S SECTOR WEIGHTINGS CHANGE DURING THE REPORTING PERIOD?

During the reporting period, the Fund's weightings relative to the MSCI EAFE(R)
Index increased in the industrials and consumer discretionary sectors. Over the
same period, the Fund's weightings declined in the financials and consumer
staples sectors.

HOW WAS THE FUND POSITIONED AT THE END OF APRIL 2010, AND HOW DID THIS
POSITIONING AFFECT THE FUND'S PERFORMANCE?

As of April 30, 2010, the Fund held overweight positions relative to the MSCI
EAFE(R) Index in the materials and consumer discretionary sectors. These
overweight positions contributed positively to the Fund's performance during the
reporting period. As of the same date, the Fund was underweight in financials
and utilities. This positioning improved the Fund's performance in April.

NOTES TO FINANCIAL STATEMENTS UNAUDITED

NOTE 1--ORGANIZATION AND BUSINESS:

MainStay Funds Trust (the "Trust") is organized as a Delaware Statutory Trust
and is governed by a Declaration of Trust dated April 8, 2009. The Trust is
registered under the Investment Company Act of 1940, as amended (the "1940
Act"), as an open-end management investment company, and is comprised of twenty-
nine funds (collectively referred to as the "Funds" and each individually,
referred to as a "Fund"). These financial statements and notes relate to the
MainStay 130/30 Core Fund, MainStay 130/30 Growth Fund and MainStay 130/30
International Fund (collectively, referred to as the "130/30 Funds" and each
individually referred to as a "130/30 Fund"). Each is a diversified fund. A
130/30 fund is a fund that invests up to approximately 130 percent of its assets
in long positions (either directly or indirectly through derivatives), while up
to approximately 30 percent of its assets are sold short (either directly or
indirectly through derivatives). The proceeds from the short strategies may be
used to purchase all or a portion of the additional 30% of the long positions.
Each 130/30 Fund is the successor of a series of Eclipse Funds Inc. with the
same name (each a "Predecessor Fund"). The reorganizations of the Predecessor
Funds with and into the respective 130/30 Funds, which were not subject to
shareholder approval under applicable law, occurred on February 26, 2010. All
information regarding and references to periods prior to the commencement of
operations of each 130/30 Fund relate to the respective Predecessor Fund.

The 130/30 Funds commenced operations as follows:

</Table>


Investor Class shares for the 130/30 Funds commenced operations on February 28,
2008.

The 130/30 Funds each currently offer four classes of shares, Investor Class,
Class A, Class C and Class I. Investor Class and Class A shares are offered at
net asset value ("NAV") per share plus an initial sales charge. No sales charge
applies on investments of $1 million or more (and certain other qualified
purchases) in Investor Class and Class A shares, but a contingent deferred sales
charge is imposed on certain redemptions of such shares within one year of the
date of purchase. Class C shares are offered at NAV without an initial sales
charge, although a 1.00% contingent deferred sales charge may be imposed on
redemptions made within one year of purchase of Class C shares. Class I shares
are offered at NAV without imposition of a front-end sales charge or a
contingent deferred sales charge. Depending upon eligibility, Investor Class
shares may convert to Class A shares and Class A shares may convert to Investor
Class shares. The four classes of shares have the same voting (except for issues
that relate solely to one class), dividend, liquidation and other rights, and
the same terms and conditions, except that Class C shares are subject to higher
distribution and/or service fee rates than Investor Class and Class A shares
under a distribution plan pursuant to Rule 12b-1 under the 1940 Act. Class I
shares are not subject to a distribution and/or service fee.

The investment objective for each of the 130/30 Funds is as follows:

The MAINSTAY 130/30 CORE FUND seeks long-term growth of capital, with income as
a secondary consideration.

The MAINSTAY 130/30 GROWTH FUND seeks long-term growth of capital.

The MAINSTAY 130/30 INTERNATIONAL FUND seeks to provide long-term growth of
capital with income as a secondary objective.

NOTE 2--SIGNIFICANT ACCOUNTING POLICIES:

The 130/30 Funds prepare their financial statements in accordance with
accounting principles generally accepted in the United States of America
("GAAP") and follow the significant accounting policies described below.

(A) SECURITIES VALUATION.  Debt securities are valued at prices supplied by a
pricing agent or broker selected by the 130/30 Funds' Manager (as defined in
Note 3(A)) in consultation with the 130/30 Funds' Subadvisor, if any, whose
prices reflect broker/dealer supplied valuations and electronic data processing
techniques, if such prices are deemed by the 130/30 Funds' Manager in
consultation with the 130/30 Funds' Subadvisor, if any, to be representative of
market values, at the regular close of trading of the New York Stock Exchange
("Exchange") (generally 4:00 p.m. Eastern time) on each day a 130/30 Fund is
open for business ("valuation date").

Equity securities are valued at the latest quoted sales prices as of the close
of regular trading on the Exchange on each valuation date. Securities that are
not traded on the valuation date are valued at the mean of the latest quoted bid
and asked prices. Prices normally are taken from the principal market in which
each security trades. Investments in other mutual funds are valued at their NAVs
as of the close of the Exchange on the valuation date. Foreign currency forward
contracts are valued at their fair market values determined on the basis of the
mean between the last current bid and ask prices based on dealer or exchange
quotations.

Loan assignments, participations and commitments are valued at the average of
bid quotations obtained from a pricing service. The Trust has engaged an
independent pricing service to provide market value quotations from dealers in
loans.

Temporary cash investments acquired over 60 days prior to maturity are valued
using the latest bid prices or using

68    MainStay 130/30 Funds



valuations based on a matrix system (which considers such factors as security
prices, yields, maturities, and ratings), both as furnished by independent
pricing services. Other temporary cash investments which mature in 60 days or
less ("short-term investments") are valued at amortized cost. The amortized cost
method involves valuing a security at its cost on the date of purchase and
thereafter assuming a constant amortization to maturity of the difference
between the principal amount due at maturity and cost.

Securities for which market quotations are not readily available are valued by
methods deemed in good faith by the 130/30 Funds' Board to represent fair value.
Equity and non-equity securities which may be valued in this manner include, but
are not limited to: (i) a security the trading for which has been halted or
suspended; (ii) a debt security that has recently gone into default and for
which there is not a current market quotation; (iii) a security of an issuer
that has entered into a restructuring; (iv) a security that has been de-listed
from a national exchange; (v) a security the market price of which is not
available from an independent pricing source or, if so provided, does not, in
the opinion of the 130/30 Fund's Manager, as defined in Note 3(A), reflect the
security's market value; and (vi) a security where the trading on that
security's principal market is temporarily closed at a time when, under normal
conditions, it would be open. At April 30, 2010, the MainStay 130/30
International Fund held a security with a value of $10, that were valued in such
a manner, while none of the other 130/30 Funds held any such securities.

Certain events may occur between the time that foreign markets close, on which
securities held by the 130/30 Funds principally trade, and the time at which
each 130/30 Fund's NAV is calculated. These events may include, but are not
limited to, situations relating to a single issue in a market sector,
significant fluctuations in U.S. or foreign markets, natural disasters, armed
conflicts, governmental actions or other developments not tied directly to the
securities markets. Should the Manager or Subadvisor, as defined in Note 3(A),
conclude that such events may have affected the accuracy of the last price
reported on the local foreign market, the Manager or Subadvisor may, pursuant to
procedures adopted by the 130/30 Funds' Board, adjust the value of the local
price to reflect the impact on the price of such securities as a result of such
events. Additionally, international equity securities are also fair valued
whenever the movement of a particular index exceeds certain thresholds. In such
cases, the securities are fair valued by applying factors provided by a third
party vendor in accordance with each 130/30 Fund's policies and procedures. At
April 30, 2010, certain foreign equity securities held by the Fund were fair
valued.

"Fair value" is defined as the price that the 130/30 Fund would receive upon
selling an investment in an orderly transaction to an independent buyer in the
principal or most advantageous market of the investment. Fair value measurements
are determined within a frame work that has established a three-tier hierarchy
which maximizes the use of observable market data and minimizes the use of
unobservable inputs to establish classification of fair value measurements for
disclosure purposes. "Inputs" refer broadly to the assumptions that market
participants would use in pricing the asset or liability, including assumptions
about risk, such as the risk inherent in a particular valuation technique used
to measure fair value using a pricing model and/or the risk inherent in the
inputs for the valuation technique. Inputs may be observable or unobservable.
Observable inputs are inputs that reflect the assumptions market participants
would use in pricing the asset or liability based on market data obtained from
sources independent of the reporting entity. Unobservable inputs are inputs that
reflect the reporting entity's own assumptions about the assumptions market
participants would use in pricing the asset or liability developed based on the
information available in the circumstances. The inputs or methodology used for
valuing securities may not be an indication of the risks associated with
investing in those securities. The three-tier hierarchy of inputs is summarized
in the three broad Levels listed below.

- - Level 1--quoted prices in active markets for identical investments

- - Level 2--other significant observable inputs (including quoted prices for
  similar investments in active markets, interest rates and yield curves,
  prepayment speeds, credit risks, etc.)

- - Level 3--significant unobservable inputs (including the 130/30 Fund's own
  assumptions about the assumptions that market participants would use in
  determining the fair value of investments)

The aggregate value by input level, as of April 30, 2010, for each 130/30 Fund's
investments is included at the end of each 130/30 Fund's Portfolio of
Investments.

The valuation techniques used by the 130/30 Funds to measure fair value during
the six-month period ended April 30, 2010 maximized the use of observable inputs
and minimized the use of unobservable inputs. The 130/30 Funds may have utilized
some of the following fair value techniques: multi-dimensional relational
pricing models, option adjusted spread pricing and estimating the price that
would have prevailed in a liquid market for an international equity security
given information available at the time of evaluation, when there are
significant events after the close of local foreign markets. For the six-month
period ended April 30, 2010, there have been no changes to the fair value
methodologies.

Generally, a security is considered illiquid if it cannot be sold or disposed of
in the ordinary course of business at approximately the price at which it is
valued. Its illiquidity might prevent the sale of such security at a time when
the Manager or Subadvisor, if any, as defined in Note 3(A)

                                                   mainstayinvestments.com    69



NOTES TO FINANCIAL STATEMENTS UNAUDITED (CONTINUED)



might wish to sell, and these securities could have the effect of decreasing the
overall level of a 130/30 Fund's liquidity. Further, the lack of an established
secondary market may make it more difficult to value illiquid securities,
requiring the 130/30 Fund to rely on judgments that may be somewhat subjective
in determining value, which could vary from the amount that the 130/30 Fund
could realize upon disposition. Difficulty in selling illiquid securities may
result in a loss or may be costly to the 130/30 Fund. Under the supervision of
the Board, the Manager or Subadvisor, if any, determines the liquidity of a
130/30 Fund's investments; in doing so, the Manager or Subadvisor, if any, may
consider various factors, including (1) the frequency of trades and quotations,
(2) the number of dealers and prospective purchasers, (3) the dealer
undertakings to make a market, and (4) the nature of the security and the market
in which it trades (e.g., the time needed to dispose of the security, the method
of soliciting offers and the mechanics of transfer). Illiquid securities
generally will be valued in such manner, as the Board in good faith deems
appropriate to reflect their fair market value.

(B) FEDERAL INCOME TAXES.  Each of the 130/30 Funds is treated as a separate
entity for federal income tax purposes. The 130/30 Funds' policy is to comply
with the requirements of the Internal Revenue Code of 1986, as amended (the
"Internal Revenue Code") applicable to regulated investment companies and to
distribute all of the taxable income to the shareholders of each 130/30 Fund
within the allowable time limits. Therefore, no federal income tax provision is
required.

Investment income received by the 130/30 Funds from foreign sources may be
subject to foreign income taxes. These foreign income taxes are generally
withheld at the source.

Management evaluates its tax positions to determine if the tax positions taken
meet the minimum recognition threshold in connection with accounting for
uncertainties in income tax positions taken or expected to be taken for the
purposes of measuring and recognizing tax liabilities in the financial
statements. Recognition of tax benefits of an uncertain tax position is required
only when the position is "more likely than not" to be sustained assuming
examination by taxing authorities. Management has analyzed the 130/30 Funds' tax
positions taken on federal income tax returns for all open tax years (current
and prior three tax years), and has concluded that no provision for federal
income tax is required in the 130/30 Funds' financial statements. The 130/30
Funds' federal and state income and federal excise tax returns for tax years for
which the applicable statutes of limitations have not expired are subject to
examination by the Internal Revenue Service and state departments of revenue.

(C) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS.  Dividends and distributions
are recorded on the ex-dividend date. The 130/30 Funds intend to declare and pay
dividends of net investment income and distributions of net realized capital
gains, if any, annually. Unless the shareholder elects otherwise, all dividends
and distributions are reinvested in the same class of shares of the respective
130/30 Fund, at NAV. Dividends and distributions to shareholders are determined
in accordance with federal income tax regulations and may differ from GAAP.

(D) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  The 130/30 Funds record
security transactions on the trade date. Realized gains and losses on security
transactions are determined using the identified cost method. Dividend income is
recognized on the ex-dividend date and interest income is accrued as earned
using the effective interest rate method. Discounts and premiums on short-term
investments are accreted and amortized, respectively, on the straight-line
method.

Investment income and realized and unrealized gains and losses on investments of
the 130/30 Funds are allocated to separate classes of shares pro rata based upon
their relative net assets on the date the income is earned or realized and
unrealized gains and losses are incurred.

(E) EXPENSES.  Expenses of the Trust are allocated to the individual 130/30
Funds in proportion to the net assets of the respective 130/30 Funds when the
expenses are incurred, except where direct allocations of expenses can be made.
Expenses (other than transfer agent expenses and fees incurred under the
shareholder services plans and the distribution plans further discussed in Note
3(B)) are allocated to separate classes of shares pro rata based upon their
relative NAV on the date the expenses are incurred. The expenses borne by each
130/30 Fund, including those of related parties to the 130/30 Funds, are shown
in the Statement of Operations.

(F) USE OF ESTIMATES.  In preparing financial statements in conformity with
GAAP, management makes estimates and assumptions that affect the reported
amounts and disclosures in the financial statements. Actual results could differ
from those estimates.

(G) REPURCHASE AGREEMENTS.  The 130/30 Funds may enter into repurchase
agreements to earn income. The 130/30 Funds may enter into repurchase agreements
only with financial institutions that are deemed by the Manager or Subadvisor to
be creditworthy, pursuant to guidelines established by the 130/30 Funds' Board.
Repurchase agreements are considered under the Investment Company Act to be
collateralized loans by a Fund to the seller secured by the securities
transferred to the Fund.

When the 130/30 Funds invest in repurchase agreements, the 130/30 Funds'
custodian takes possession of the collateral pledged for investments in such
repurchase agreements. The underlying collateral is valued daily on a mark-to-
market basis to determine that the value, including accrued interest, exceeds
the repurchase price. In the event of the seller's default of the obligation to
repurchase, the

70    MainStay 130/30 Funds



130/30 Funds have the right to liquidate the collateral and apply the proceeds
in satisfaction of the obligation. Under certain circumstances, in the event of
default or bankruptcy by the other party to the agreement, realization and/or
retention of the collateral may be subject to legal proceedings.

(H) SWAP AGREEMENTS.  The MainStay 130/30 International Fund enters into credit
default, interest rate, index and currency exchange rate swap agreements
("swaps") for purposes of attempting to obtain a particular desired return at a
lower cost to the 130/30 Fund than if the 130/30 Fund had invested directly in
an instrument that yielded the desired return or for other portfolio management
purposes. In a standard swaps transaction, two parties agree to exchange the
returns (or differentials in rates of return) earned or realized on particular
predetermined investments or instruments. The gross returns to be exchanged or
"swapped" between the parties are calculated with respect to a "notional
amount." Credit default swaps are contracts whereby one party makes periodic
payments to a counterparty in exchange for the right to receive a specified
return in the event of a default by a third party on its obligation. Credit
default swaps may be used to provide a measure of protection against defaults of
sovereign or corporate issuers. In connection with these agreements, cash or
securities may be set aside as collateral in accordance with the terms of the
swap agreement.

The MainStay 130/30 International Fund enters into total return swap agreements
for the purpose of attempting to obtain a particular desired return at a lower
cost to the Fund than if the Fund had invested directly in an instrument that
yielded the desired return or for other portfolio management purposes. Total
return swap agreements are two party contracts entered into primarily by
institutional investors for periods ranging from a few weeks to more than one
year. In a standard "total return swap" transaction, two parties agree to
exchange the returns (or differentials in rates of return) earned or realized on
particular predetermined investments or instruments. The gross returns to be
exchanged or "swapped" between the parties are calculated with respect to a
"notional amount," i.e., the return on or increase in value of a particular
dollar amount invested in a particular foreign currency, or in a "basket" of
securities representing a particular index. The "notional amount" of the total
return swap agreement is only a fictive basis on which to calculate the
obligations that the parties to a swap agreement have agreed to exchange. Most
swap agreements entered into by the MainStay 130/30 International Fund would
calculate the obligations of the parties to the agreements on a "net" basis.
Consequently, a 130/30 Fund's obligations (or rights) under a swap agreement
will generally be equal only to the net amount to be paid or received under the
agreement based on the relative values of the positions held by each party to
the agreement (the "net amount"). The MainStay 130/30 International Fund's
obligation under a swap agreement will be accrued daily (offset against any
amounts owing to the MainStay 130/30 International Fund).

In a typical cap or floor agreement, one party agrees to make payments only
under specified circumstances, usually in return for payment of a fee by the
other party. For example, the buyer of an interest rate cap obtains the right to
receive payments to the extent that a specified interest rate exceeds an agreed-
upon level, while the seller of an interest rate floor is obligated to make
payments to the extent that a specified interest rate falls below an agreed-upon
level. An interest rate collar combines elements of buying a cap and selling a
floor.

The 130/30 International Fund bears the risk of loss of the amount expected to
be received under a swap agreement in the event of the default or bankruptcy of
a swap agreement counterparty. The 130/30 International Fund may be able to
eliminate its exposure under a swap agreement either by assignment or other
disposition, or by entering into an offsetting swap agreement with the same
party or a similarly creditworthy party.

Swaps are marked to market daily based upon quotations from market makers and
vendors and the change in value, if any, is recorded as unrealized gain or loss.
Payments received or made on swap contracts are recorded as realized gain or
loss. Gains or losses are realized upon early termination of the swap
agreements. These financial instruments are not actively traded on financial
markets. Entering into these agreements involves elements of credit, market and
documentation risk in excess of the amounts recognized on the Statement of
Assets and Liabilities. Such risks involve the possibility that there will be no
liquid market for these agreements, that the counterparty to the agreements may
default on its obligation to perform or disagree as to the meaning of the
contractual terms in the agreements and that there may be unfavorable changes in
interest rates or the price of the index or security underlying these
transactions.

(I) SECURITIES SOLD SHORT.  The 130/30 Funds typically engage in short sales as
part of their investment strategies. When a Fund enters into a short sale, it
must segregate the cash proceeds from the security sold short or other
securities, as collateral for its obligation to deliver the security upon
conclusion of the sale. A gain, limited to the price at which the 130/30 Funds
sold the security short, or a loss, unlimited as to dollar amount, will be
recognized upon termination of a short sale if the market price on the date the
short position is closed out is less or greater, respectively, than the proceeds
originally received. Any such gain or loss may be offset, completely or in part,
by the change in the value of the hedged investments. Accrued interest income
and dividends declared on short positions existing on the record date are
recorded on the ex-dividend date as an interest expense and dividend expense,
respectively, on the Statement of Operations.

NOTES TO FINANCIAL STATEMENTS UNAUDITED (CONTINUED)


(J) STATEMENT OF CASH FLOWS.  The cash amount shown in the Statement of Cash
Flows of each 130/30 Fund is the amount included in the 130/30 Fund's Statement
of Assets and Liabilities and represents the cash on hand at its custodian and
does not include any short-term investments or deposit at brokers for securities
sold short. Cash may include domestic and foreign currency.

(K) FOREIGN CURRENCY FORWARD CONTRACTS.  A foreign currency forward contract is
an agreement to buy or sell currencies of different countries on a specified
future date at a specified rate. During the period the forward contract is open,
changes in the value of the contract are recognized as unrealized gains or
losses by "marking to market" such contract on a daily basis to reflect the
market value of the contract at the end of each day's trading. When the forward
contract is closed, the 130/30 Funds record a realized gain or loss equal to the
difference between the proceeds from (or cost of) the closing transaction and
the 130/30 Funds' basis in the contract. The 130/30 Funds enter into foreign
currency forward contracts primarily to hedge their foreign currency denominated
investments and receivables and payables against adverse movements in future
foreign exchange rates or to try to enhance the 130/30 Funds' returns.

The use of foreign currency forward contracts involves, to varying degrees,
elements of market risk in excess of the amount recognized in the Statement of
Assets and Liabilities. The contract amount reflects a extent of a 130/30 Fund's
involvement in these financial instruments. Risks arise from the possible
movements in the foreign exchange rates underlying these instruments. While the
130/30 Funds may enter into forward contracts to reduce currency exchange risks,
changes in currency exchange rates may result in poorer overall performance for
the 130/30 Funds than if they had not engaged in such transactions. Exchange
rate movements can be large, depending on the currency, and can last for
extended periods of time, affecting the value of the 130/30 Funds' assets.
Moreover, there may be an imperfect correlation between the 130/30 Funds'
holdings of securities denominated in a particular currency and the forward
contracts entered into by the 130/30 Funds. Such imperfect correlation may
prevent the 130/30 Funds from achieving the intended hedge or expose the 130/30
Funds to the risk of currency exchange loss. The unrealized appreciation
(depreciation) on forward contracts reflects a 130/30 Fund's exposure at period
end to credit loss in the event of a counterparty's failure to perform its
obligations. (See Note 5.)

(L) FOREIGN CURRENCY TRANSACTIONS.  The books and records of the 130/30 Funds
are kept in U.S. dollars. Prices of securities denominated in foreign currency
amounts are translated into U.S. dollars at the mean between the buying and
selling exchange rates last quoted by any major U.S. bank at the following
dates:

(i) market value of investment securities, other assets and liabilities--at the
    valuation date, and

(ii) purchases and sales of investment securities, income and expenses--at the
     date of such transactions.

The assets and liabilities that are denominated in foreign currency amounts are
presented at the exchange rates and market values at the close of the period.
The realized and unrealized changes in net assets arising from fluctuations in
exchange rates and market prices of securities are not separately presented.

Net realized gain (loss) on foreign currency transactions represents net gains
and losses on foreign currency forward contracts, net currency gains or losses
realized as a result of differences between the amounts of securities sale
proceeds or purchase cost, dividends, interest and withholding taxes as recorded
on the 130/30 Funds' books, and the U.S. dollar equivalent amount actually
received or paid. Net currency gains or losses from valuing such foreign
currency denominated assets and liabilities, other than investments at valuation
date exchange rates, are reflected in unrealized foreign exchange gains or
losses.

(M) RIGHTS/WARRANTS.  A right is a certificate that permits the holder to
purchase a certain number of shares, or a fractional share, of a new stock from
the issuer at a specific price. A warrant is an instrument that entitles the
holder to buy an equity security at a specific price for a specific period of
time. The 130/30 Funds enter into rights and warrants when securities are
acquired through a corporate action. With respect to warrants in international
markets, the securities are only purchased when the underlying security can not
be purchased due to the many restrictions an industry and/or country might place
on foreign investors. These investments can provide a greater potential for
profit or loss than an equivalent investment in the underlying security. Prices
of these investments do not necessarily move in tandem with the prices of the
underlying securities, and are speculative investments.

There is risk involved in the purchase of rights and warrants in that these
investments are speculative investments. The 130/30 Funds could also lose the
entire value of the investment in warrants if the warrant is not exercised by
the date of its expiration. The 130/30 Funds invest in warrants only if received
as part of a corporate action. The securities are sold as soon as the
opportunity becomes available. The 130/30 Funds are exposed to risk until each
sale is completed.

(N) REDEMPTION FEE.  Prior to April 1, 2010, the MainStay 130/30 International
Fund imposed a 2.00% redemption fee on redemptions (including exchanges) of Fund
shares made within 60 days of their date of purchase for any class. The
redemption fee was designed to offset

72    MainStay 130/30 Funds



brokerage commissions and other costs associated with short-term trading and was
not assessed on shares acquired through the reinvestment of dividends or
distributions paid by the Fund. The redemption fees are included in the
Statement of Changes in Net Assets' shares redeemed amount and are retained by
the Fund.

(O) CONCENTRATION OF RISK.  The MainStay 130/30 International Fund invests in
foreign securities, which carry certain risks that are in addition to the usual
risks inherent in domestic instruments. These risks include those resulting from
currency fluctuations, future adverse political and economic developments and
possible imposition of currency exchange blockages or other foreign governmental
laws or restrictions. These risks are likely to be greater in emerging markets
than in developed markets. The ability of issuers of debt securities held by the
MainStay 130/30 International Fund to meet its obligations may be affected by
economic or political developments in a specific country, industry or region.

(P) INDEMNIFICATIONS.  Under the Trust's organizational documents, its officers
and trustees are indemnified against certain liabilities that may arise out of
performance of their duties to the Trust. Additionally, in the normal course of
business, the 130/30 Funds enter into contracts with third-party service
providers that contain a variety of representations and warranties and which
provide general indemnifications. The 130/30 Funds' maximum exposure under these
arrangements is unknown, as this would involve future claims that may be made
against the 130/30 Funds that have not yet occurred. Based on experience,
management is of the view that the risk of loss in connection with these
potential indemnification obligations is remote. However, there can be no
assurance that material liabilities related to such obligations will not arise
in the future, which could adversely impact the 130/30 Funds.

(Q) QUANTITATIVE DISCLOSURE OF DERIVATIVE HOLDINGS.  The following tables show
additional disclosures about the 130/30 Funds' derivative and hedging
activities, including how such activities are accounted for and their effect on
the 130/30 Funds' financial positions, performance and cash flows. These
derivatives are not accounted for as hedging instruments.

NOTE 3--FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER AND SUBADVISOR.  New York Life Investment Management LLC ("New York
Life Investments" or "Manager"), a registered investment adviser and an
indirect, wholly-owned subsidiary of New York Life Insurance Company ("New York
Life"), serves as the 130/30 Funds' Manager, pursuant to a Management Agreement,

Except for the portion of salaries and expenses that are the responsibility of
the 130/30 Funds, the Manager also pays the salaries and expenses of all
personnel affiliated with the 130/30 Funds and the operational expenses of the
130/30 Funds. Madison Square Investors LLC ("Madison Square Investors" or
"Subadvisor"), a registered investment adviser and an indirect, wholly-owned
subsidiary of New York Life, serves as subadvisor to and manages the day-to-day
investment operations of the 130/30 Funds. Pursuant to the terms of a
Subadvisory Agreement ("Subadvisory Agreement") between New York Life
Investments and Madison Square Investors, New York Life Investments pays for the
Subadvisor's services.

Each 130/30 Fund is contractually obligated to pay the Manager a monthly fee for
services performed and facilities furnished at an annual rate of average daily
net assets of that 130/30 Fund as follows:

limitation agreements under which it has agreed to waive a portion of the

expenses (total ordinary operating expenses excludes taxes, interest,
litigation, dividends and interest expense on securities sold short,
extraordinary expenses, brokerage, other transaction expenses relating to the
purchase or sale of portfolio investments and the fees and expenses of any other
funds in which a 130/30 Fund invests) do not exceed the percentages of average
daily net assets for Class A as set forth in the table below. New York Life
investments will apply an equivalent waiver or reimbursement, in an equal number
of basis points, to the other share classes of each 130/30 Fund. This agreement
expires on July 31, 2010 and is reviewed annually by the Board in connection
with its review of each 130/30 Fund's investment advisory agreements. Based on
its review, the Board may agree to maintain, modify or terminate the agreement.

NOTE 6--CUSTODIAN:

State Street is the custodian of the cash and the securities of the 130/30
Funds. Custodial fees are charged to the 130/30 Funds based on the market value
of securities in the 130/30 Funds and the number of certain cash transactions
incurred by the 130/30 Funds.

NOTE 7--LINE OF CREDIT:

The 130/30 Funds and certain affiliated funds maintain a line of credit of
$125,000,000 with a syndicate of banks in order to secure a source of funds for
temporary purposes to meet unanticipated or excessive shareholder redemption
requests.

The line of credit is in the amount of $125,000,000 and the commitment fee rate
is an annual rate of 0.10% of the average commitment amount, plus a 0.04% up-
front payment payable, regardless of usage, to The Bank of New York Mellon,
which serves as agent to the syndicate. The commitment fee and upfront payment
are allocated among certain MainStay 130/30 Funds based upon net assets and
other factors. Interest on any revolving credit loan is charged based upon the
Federal Funds Advances rate or the one month LIBOR rate, whichever is higher.
There were no borrowings made or outstanding with respect to the 130/30 Funds on
the line of credit during the six-month period ended April 30, 2010.

NOTE 8--PURCHASES AND SALES OF SECURITIES (IN 000'S):

(a) In addition to any automatic conversion features described above in Note 1
    with respect to Investor Class, Class A and B shares, you generally may also
    elect to convert your shares on a voluntary basis into another share class
    of the same fund for which you are eligible. However, the following
    limitations apply:

  - Investor Class and Class A shares that remain subject to a CDSC are
    ineligible for a voluntary conversion; and

  - All Class B and C shares are ineligible for a voluntary conversion.

These limitations do not impact any automatic conversion features described in
Note 1 with respect to Investor Class, Class A and B shares.

An investor or an investor's financial intermediary may contact the Fund to
request a voluntary conversion between shares classes of the same Fund. You may
be required to provide sufficient information to establish eligibility to
convert to the new share class. All permissible conversions will be made on the
basis of the relevant NAVs of the two classes without the imposition of any
sales load, fee or other charge. If you fail to remain eligible for the new
share class, you may automatically be converted back to your original share
class, or into another share class, if appropriate.

Measurements". ASU 2010-06 requires reporting entities to make new disclosures
about amount and reasons for significant transfers in and out of Level 1 and
Level 2 fair value measurements and input and valuation techniques used to
measure fair value for both recurring and nonrecurring fair value measurements
that fall in either Level 2 or Level 3, and information on purchased, sales,

measures. The new and revised disclosure requirements are effective for interim
and annual reporting periods beginning after December 15, 2009 except for the
disclosures about purchased, sales, issuances, and settlements in the roll
forward of activity in Level 3 fair value measures, which are effective for
fiscal years beginning after December 15, 2010. As of April 30, 2010, the Fund
has adopted ASU 2010-06. The adoption of ASU 2010-06 has not impacted the

        MESSAGE FROM THE PRESIDENT AND SEMIANNUAL REPORT

        Unaudited - April 30, 2010



MESSAGE FROM THE PRESIDENT

During the six months ended April 30, 2010, stock and bond markets generally
advanced, despite some volatility in January and February. Domestic small-cap
stocks were particularly strong, and U.S. stocks at all capitalization levels
provided double digit returns. Value stocks outpaced growth stocks for companies
of all sizes during the reporting period.

International stocks provided positive returns overall, but results varied
widely by country. Concerns about Greece's ability to meet its debt obligations
led many investors to abandon their holdings in Greece and question their
investments in several peripheral European nations where perceived risk had
increased. For the six-month reporting period, equities in the Far East
(including Japan) tended to be stronger than those in Europe.

The economic recovery in the United States continued. Real gross domestic
product advanced in the first quarter of 2010, though at a slower pace than in
the fourth quarter of 2009. The Federal Open Market Committee kept the targeted
federal funds rate at a historically low level throughout the reporting period,
which prompted many investors to leave the safety of U.S. Treasury securities in
search of higher yield.

In the high-yield bond market, lower-rated credits tended to be the strongest
performers. With investment-grade investors crossing into high-yield territory,
however, the highest-rated high-yield credits also saw strong demand. In the
municipal market, new-issue supply was reduced by government incentives that
encouraged municipal issuers to raise funds in the taxable market. In the
leveraged-loan market, new issuance strengthened, but extensive repayments
caused the market as a whole to contract.


Throughout the six-month reporting period, MainStay's portfolio managers sought
to make the most of market conditions within the investment strategies and risk
parameters of their respective Funds. While individual markets and Fund results
may vary, our pursuit of competitive returns over full market cycles has never
changed.

The information that follows provides a closer look
at the securities, strategies and market conditions that affected your MainStay
Fund(s) during the six months ended April 30, 2010. Of course, past performance
is no guarantee of future results. Even in a rising market, we believe that
maintaining a long-term perspective can be valuable. At MainStay, we believe
that in all markets, broad diversification, gradual allocation adjustments and
regular portfolio reviews can help guide you toward your long-range financial
goals.

We thank you for choosing MainStay Funds, and we look forward to serving your
investment needs for many years to come.

Sincerely,

/s/ STEPHEN P. FISHER

Stephen P. Fisher
President

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY CASH RESERVES FUND
(UNAUDITED)
- --------------------------------------------------------------------------------

The example below is intended to describe the fees and expenses borne by
shareholders during the six-month period from November 1, 2009, to April 30,
2010, and the impact of those costs on your investment.

EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, exchange fees, and sales charges (loads) on
purchases (as applicable), and (2) ongoing costs, including management fees,
distribution and/or service (12b-1) fees, and other Fund expenses (as
applicable). This example is intended to help you understand your ongoing costs
(in dollars) of investing in the Fund and to compare these costs with the
ongoing costs of investing in other mutual funds. The example is based on an
investment of $1,000 made at the beginning of the six-month period and held for
the entire period from November 1, 2009, to April 30, 2010.

This example illustrates your Fund's ongoing costs in two ways:

- - ACTUAL EXPENSES
The second and third data columns in the table below provide information about
actual account values and actual expenses. You may use the information in these
columns, together with the amount you invested, to estimate the expenses that
you paid during the six-months ended April 30, 2010. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number under the heading entitled "Expenses Paid
During Period" to estimate the expenses you paid on your account during this
period.

- - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The fourth and fifth data columns in the table below provide information about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense ratio and an assumed rate of return of 5% per year before expenses,
which is not the Fund's actual return. The hypothetical account values and
expenses may not be used to estimate the actual ending account balances or
expenses you paid for the six-month period shown. You may use this information
to compare the ongoing costs of investing in the Fund with the ongoing costs of
investing in other Funds. To do so, compare this 5% hypothetical example with
the 5% hypothetical examples that appear in the shareholder reports of the other
Funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as
redemption fees, if applicable, exchange fees, or sales charges (loads).
Therefore, the fourth and fifth data columns of the table are useful in
comparing ongoing costs only and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.

1. Expenses are equal to the Fund's annualized expense ratio of each class
   (0.24% for Class I Shares and Sweep Shares) multiplied by the average account
   value over the period, divided by 365 and multiplied by 181 (to reflect the
   one-half year period). The table above represents the actual expenses
   incurred during the one-half year period.

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

QUESTIONS ANSWERED BY PORTFOLIO MANAGERS DAVID E. CLEMENT, CFA, AND THOMAS J.
GIRARD OF NEW YORK LIFE INVESTMENTS,(1) THE FUND'S MANAGER.

HOW DID MAINSTAY CASH RESERVES FUND PERFORM RELATIVE TO ITS PEERS DURING THE SIX
MONTHS ENDED APRIL 30, 2010?

As of April 30, 2010, MainStay Cash Reserves Fund Class I shares and Sweep
Shares each provided a 7-day current yield of 0.01% and a 7-day effective yield
of 0.01%. For the six months ended April 30, 2010, MainStay Cash Reserves Fund
Class I shares and Sweep Shares returned 0.00%. Both share classes
underperformed the 0.03% return of the Lipper(2) institutional money market
funds average for the six months ended April 30, 2010. Class I shares and Sweep
Shares also underperformed the 0.01% return of the Lipper money market funds
average for the six months ended April 30, 2010.

WHAT ECONOMIC AND MARKET FORCES AFFECTED THE FUND DURING THE REPORTING PERIOD?

The Federal Open Market Committee (FOMC) maintained its targeted federal funds
rate in a range from 0% to 0.25% throughout the reporting period. This decision
affected short-term interest rates and resulted in a lower yield in the Fund.

The supply of commercial paper and corporate bonds of industrial issuers
remained sparse. In addition, the anticipation of new Securities and Exchange
Commission (SEC) regulations affected supply/demand characteristics along both
the yield curve and the credit curve,(3) even though these regulations did not
begin to take effect until after the end of the reporting period. In particular,
the yield curve steepened and the credit curve widened. The yield curve
steepened because the new regulations call for higher levels of liquidity,
creating higher demand for securities with shorter maturities. The credit curve
widened because the new regulations also decreased the amount of allowable
investments in second tier commercial paper.

HOW DID YOU MANAGE THE FUND'S DURATION DURING THE REPORTING PERIOD?

The Fund initially had a longer-than-normal duration to take advantage of higher
yields further out the yield curve. Over the course of the reporting period, we
shortened the Fund's duration from 72 days to 55 days. The shorter duration
reflected our expectation that rates would rise later this year. It also
reflected the flatter yield curve we saw for a good portion of the reporting
period. Duration was also shortened to prepare the Fund for new SEC regulations.
In light of these new regulations, effective May 26, 2010, the Fund maintains a
dollar-weighted average maturity of 60 days or less and a dollar-weighted
average life to maturity of 120 days or less. For more information, please refer
to the relevant supplement to the Fund's prospectus dated May 26, 2010.

DURING THE REPORTING PERIOD, WHICH MARKET SEGMENTS WERE POSITIVE CONTRIBUTORS TO
THE FUND'S PERFORMANCE AND WHICH MARKET SEGMENTS DETRACTED?

The major positive contributors to the Fund's performance included Federal
Deposit Insurance Corporation (FDIC) backed paper, Treasury coupons and agency
coupons. The Fund's return was hampered by repurchase agreements and by
commercial paper of industrial issuers. In addition, the Fund's yields were
dampened because of relatively limited exposure to banks and asset-backed
commercial paper.

WHICH POSITIONS WERE STRONG CONTRIBUTORS TO THE FUND'S PERFORMANCE DURING THE
REPORTING PERIOD?

One of the significant investments during the reporting period was a Berkshire
Hathaway floating-rate security (due February 2011), which offered incremental
yield relative to commercial paper investments.

Other significant purchases included investments in a number of asset-backed
securities, which allowed the Fund to pick up yield by extending out an upward
sloping curve and by investing in securities that were less expensive than
commercial paper. A few examples include CNH Equipment Trust and John Deere
Owner Trust paper as well as BMW Vehicle Owner Trust and Mercedes-Benz Auto
Receivables Trust.

Finally, we were able to augment the Fund's yield in the agency sector through
investments in supranationals, such as the International Bank for Reconstruction
and Development (World Bank) and the Inter-American Development Bank.

3. The yield curve is a line that plots the yields of various securities of
   similar quality--typically U.S. Treasury issues--across a range of
   maturities. The U.S. Treasury yield curve serves as a benchmark for other
   debt and is used in economic forecasting. The credit curve reflects credit
   spreads (the difference in yield between U.S. Treasurys and credit
   securities) across different maturities.

WERE THERE ANY SIGNIFICANT WEIGHTING CHANGES DURING THE REPORTING PERIOD?

During the reporting period, we increased the Fund's weightings in asset-backed
securities and repurchase agreements. The Fund decreased its weighting in the
commercial paper sector.

NOTES TO FINANCIAL STATEMENTS UNAUDITED

NOTE 1--ORGANIZATION AND BUSINESS:

MainStay Funds Trust (the "Trust") is organized as a Delaware Statutory Trust
and is governed by a Declaration of Trust dated April 8, 2009. The Trust is
registered under the Investment Company Act of 1940, as amended (the "1940
Act"), as an open-end management investment company, and is comprised of twenty-
nine funds (collectively referred to as the "Funds"). These financial statements
and notes relate only to the MainStay Cash Reserves Fund (the "Fund"), a
diversified fund. The Fund is the successor of the MainStay Cash Reserves Fund,
a series of Eclipse Funds Inc. (the "Predecessor Fund"). The reorganization of
the Predecessor Fund with and into the Fund, which was not subject to
shareholder approval under applicable law, occurred on February 26, 2010. All
information regarding and references to periods prior to the commencement of
operations of the Fund relate to the Predecessor Fund.

The Fund currently offers two classes of shares. Class I shares commenced
operations on January 2, 1991. The Sweep Shares commenced operations on December
8, 1998. The Fund's No-Load Class shares were redesignated as Class I shares on
January 1, 2004. Class I shares and the Sweep Shares are offered at net asset
value ("NAV") without imposition of a front-end sales charge or a contingent
deferred sales charge. Each class of shares have the same voting (except for
issues that relate solely to one class), dividend, liquidation and other rights
and the same terms and conditions, except that the classes are subject to
different distribution fee rates. The Sweep Shares bear distribution and service
fee payments under a distribution and service plan pursuant to Rule 12b-1 under
the 1940 Act. In addition, the Sweep Shares shareholders bear service fee
payments under a shareholder service plan. Class I shares of the Fund are not
subject to a distribution or service fee.

The Fund's investment objective is to seek a high level of current income while
preserving capital and maintaining liquidity.

NOTE 2--SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with accounting
principles generally accepted in the United States of America ("GAAP") and
follows the significant accounting policies described below.

(A) VALUATION OF FUND SHARES.  The Fund seeks to maintain a NAV of $1.00 per
share, although there is no assurance that it will be able to do so on a
continuous basis, and it has adopted certain investment, portfolio and dividend
and distribution policies designed to enable it to do as such. An investment in
the Fund is not insured or guaranteed by the Federal Deposit Insurance
Corporation or any other government agency.

(B) SECURITIES VALUATION.  Securities are valued at their amortized cost. The
amortized cost method involves valuing a security at its cost on the date of
purchase and thereafter assuming a constant amortization to maturity of the
difference between such cost and the value on maturity date.

"Fair value" is defined as the price that the Fund would receive upon selling an
investment in an orderly transaction to an independent buyer in the principal or
most advantageous market of the investment. Fair value measurements are
determined within a framework that has established a three-tier hierarchy which
maximizes the use of observable market data and minimizes the use of
unobservable inputs to establish classification of fair value measurements for
disclosure purposes. "Inputs" refer broadly to the assumptions that market
participants would use in pricing the asset or liability, including assumptions
about risk, such as the risk inherent in a particular valuation technique used
to measure fair value using a pricing model and/or the risk inherent in the
inputs for the valuation technique. Inputs may be observable or unobservable.
Observable inputs are inputs that reflect the assumptions market participants
would use in pricing the asset or liability based on market data obtained from
sources independent of the reporting entity. Unobservable inputs are inputs that
reflect the reporting entity's own assumptions about the assumptions market
participants would use in pricing the asset or liability developed based on the
information available in the circumstances. The inputs or methodology used for
valuing securities may not be an indication of the risks associated with
investing in those securities. The three-tier hierarchy of inputs is summarized
in the three broad Levels listed below.

- - Level 1--quoted prices in active markets for identical investments

- - Level 2--other significant observable inputs (including quoted prices for
  similar investments in active markets, interest rates and yield curves,
  prepayment speeds, credit risks, etc.)

- - Level 3--significant unobservable inputs (including the Fund's own assumptions
  about the assumptions that market participants would use in determining the
  fair value of investments)

The aggregate value by input level, as of April 30, 2010, for the Fund's
investments is included at the end of the Fund's Portfolio of Investments.

The valuation techniques used by the Fund to measure fair value during the six-
month period ended April 30, 2010 maximized the use of observable inputs and
minimized the use of unobservable inputs. The Fund may have utilized some of the
following fair value techniques: multi-dimensional relational pricing models,
option adjusted spread pricing and estimating the price that would have
prevailed in a liquid market for an international equity security given
information available at the time of evaluation, when there are significant
events after the close of local foreign markets.

22    MainStay Cash Reserves Fund



For the six-month period ended April 30, 2010, there have been no changes to the
fair value methodologies.

(C) FEDERAL INCOME TAXES.  The Fund's policy is to comply with the requirements
of the Internal Revenue Code of 1986, as amended (the "Internal Revenue Code")
applicable to regulated investment companies and to distribute all of the
taxable income to the shareholders of the Fund within the allowable time limits.
Therefore, no federal income tax provision is required.

Management evaluates its tax positions to determine if the tax positions taken
meet the minimum recognition threshold in connection with accounting for
uncertainties in income tax positions taken or expected to be taken for the
purposes of measuring and recognizing tax liabilities in the financial
statements. Recognition of tax benefits of an uncertain tax position is required
only when the position is "more likely than not" to be sustained assuming
examination by taxing authorities. Management has analyzed the Fund's tax
positions taken on federal income tax returns for all open tax years (current
and prior three tax years), and has concluded that no provision for federal
income tax is required in the Fund's financial statements. The Fund's federal
and state income and federal excise tax returns for tax years for which the
applicable statutes of limitations have not expired are subject to examination
by the Internal Revenue Service and state departments of revenue.

(D) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS.  Dividends and distributions
are recorded on the ex-dividend date. The Fund declares dividends of net
investment income daily and the Fund pays them monthly and declares and pays
distributions of net realized capital gains, at least annually, if any. Unless
the shareholder elects otherwise, all dividends and distributions are reinvested
in the same class of shares of the Fund, at NAV. Dividends and distributions to
shareholders are determined in accordance with federal income tax regulations
and may differ from GAAP.

(E) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  The Fund records security
transactions on the trade date. Realized gains and losses on security
transactions are determined using the identified cost method. Interest income is
accrued daily and discounts and premiums on securities purchased for the Fund
are accreted and amortized, respectively, on the straight-line method.

Investment income and realized and unrealized gains and losses on investments of
the Fund are allocated to separate classes of shares pro rata based upon their
relative net assets on the date the income is earned or realized and unrealized
gains and losses are incurred.

(F) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred, except where direct allocations of expenses can be made. Expenses
(other than transfer agent expenses and fees incurred under the shareholder
services plans and the distribution plans further discussed in Note 3(B)) are
allocated to separate classes of shares pro rata based upon their relative NAV
on the date the expenses are incurred. The expenses borne by the Fund, including
those of related parties to the Fund, are shown in the Statement of Operations.

(G) USE OF ESTIMATES.  In preparing financial statements in conformity with
GAAP, management makes estimates and assumptions that affect the reported
amounts and disclosures in the financial statements. Actual results could differ
from those estimates.

(H) REPURCHASE AGREEMENTS.  The Fund may enter into repurchase agreements to
earn income. The Fund may enter into repurchase agreements only with financial
institutions that are deemed by the Manager to be creditworthy, pursuant to
guidelines established by the Fund's Board. Repurchase agreements are considered
under the 1940 Act to be collateralized loans by a Fund to the seller secured by
the securities transferred to the Fund.

When the Fund invests in repurchase agreements, the Fund's custodian takes
possession of the collateral pledged for investments in such repurchase
agreements. The underlying collateral is valued daily on a mark-to-market basis
to determine that the value, including accrued interest, exceeds the repurchase
price. In the event of the seller's default of the obligation to repurchase, the
Fund has the right to liquidate the collateral and apply the proceeds in
satisfaction of the obligation. Under certain circumstances, in the event of
default or bankruptcy by the other party to the agreement, realization and/or
retention of the collateral may be subject to legal proceedings and possible
realized loss to the Fund.

(I) INDEMNIFICATIONS.  Under the Trust's organizational documents, its officers
and trustees are indemnified against certain liabilities that may arise out of
performance of their duties to the Trust. Additionally, in the normal course of
business, the Fund enters into contracts with third-party service providers that
contain a variety of representations and warranties and which provide general
indemnifications. The Fund's maximum exposure under these arrangements is
unknown, as this would involve future claims that may be made against the Fund
that have not yet occurred. Based on experience, management is of the view that
the risk of loss in connection with these potential indemnification obligations
is remote. However, there can be no assurance that material liabilities related
to such obligations will not arise in the future, which could adversely impact
the Fund.

NOTE 3--FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER.  New York Life Investment Management LLC ("New York Life
Investments" or "Manager"), a registered investment adviser and an indirect,
wholly-owned

                                                   mainstayinvestments.com    23



NOTES TO FINANCIAL STATEMENTS UNAUDITED (CONTINUED)



subsidiary of New York Life Insurance Company ("New York Life"), serves as the
Fund's Manager, pursuant to a Management Agreement, as amended ("Management
Agreement"). The Manager provides offices, conducts clerical, recordkeeping and
bookkeeping services, and keeps most of the financial and accounting records
required to be maintained by the Fund. Except for the portion of salaries and
expenses that are the responsibility of the Fund, the Manager also pays the
salaries and expenses of all personnel affiliated with the Fund and the
operational expenses of the Fund. The Fund is advised by New York Life
Investments directly, without a subadvisor.

The Fund pays the Manager a monthly fee for services performed and facilities
furnished at an annual rate of the Fund's average daily net assets as follows:
0.45% on assets up to $500 million, 0.40% on assets from $500 million to $1
billion and 0.35% on assets in excess of $1 billion. The effective management
fee rate (exclusive of any applicable waivers/reimbursements) was 0.43% for the
six-month period ended April 30, 2010.

Effective August 1, 2009, New York Life Investments entered into a written
expense limitation agreement under which it has agreed to waive a portion of the
Fund's management fee or reimburse the expenses of the appropriate class of the
Fund so that total ordinary operating expenses of a class (total ordinary
operating expenses excludes taxes, interest, litigation, extraordinary expenses,
brokerage, and other transaction expenses relating to the purchase or sale of
portfolio investments) do not exceed the following percentages of average daily
net assets: Class I, 0.50%; and Sweep Shares, 1.00%. This agreement expires on
February 28, 2011 and is reviewed annually by the Board in connection with its
review of the Fund's investment advisory agreements. Based on its review, the
Board may agree to maintain, modify or terminate the agreement.

From time to time, the Manager may limit expenses of the Fund to the extent it
deems appropriate to enhance the yield of the Fund, or a particular class of the
Fund, during periods when expenses have a significant impact on the yield of the
Fund, or a particular class of the Fund, as applicable, because of low interest
rates. This expense limitation policy is voluntary and in addition to any
contractual arrangements that may be in place with respect to the Fund described
in the Fund's prospectus. It may be revised or terminated by the Manager at any
time without notice.

For the six-month period ended April 30, 2010, New York Life Investments earned
fees from the Fund in the amount of $1,651,930 and waived/reimbursed its fees in
the amount of $2,354,879.

State Street Bank and Trust Company ("State Street"), 1 Lincoln Street, Boston,
Massachusetts 02111, provides sub-administration and sub-accounting services to
the Fund pursuant to an agreement with New York Life Investments. These services
include calculating the daily NAVs of the Fund, maintaining the general ledger
and sub-ledger accounts for the calculation of the Fund's respective NAVs, and
assisting New York Life Investments in conducting various aspects of the Fund's
administrative operations. For providing these services to the Fund, State
Street is compensated by New York Life Investments.

(B) DISTRIBUTION AND SERVICE FEES.  NYLIFE Distributors LLC (the "Distributor")
serves as the Fund's distributor and principal underwriter. The Trust, on behalf
of the Fund, has a Distribution Agreement with the Distributor. The Trust, with
respect to the Sweep Shares of the Fund, has adopted a distribution and service
plan (the "Plan") in accordance with the provisions of Rule 12b-1 under the 1940
Act. The Plan provides that distribution and service fees payable there under
are payable to the Distributor regardless of the amounts actually expended by
the Distributor for distribution of the Fund's Sweep Shares and service
activities. Class I shares of the Fund are not subject to a distribution or
service fee.

Pursuant to the Plan, the Distributor, NYLIFE Securities Inc., an indirect,
wholly-owned subsidiary of New York Life, or any other broker-dealer or other
financial institution, are entitled to receive a monthly distribution fee, which
is an expense of the Plan of the Fund, for distribution or service activities as
designated by the Distributor, at an annual rate of 0.25% of the average daily
net assets of the Fund's Sweep Shares for account sweep and other distribution-
related and shareholder services.

In accordance with a separate Shareholder Service Plan, the Manager has agreed
to provide, through its affiliates or independent third parties, various
shareholder and administrative support services to shareholders of the Sweep
Shares. For its services, the Manager is entitled to a Shareholder Service Fee
accrued daily and paid monthly at an annual rate of 0.25% of the average daily
net assets attributable to the Sweep Shares of the Fund.

(C) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT.  NYLIM
Service Company LLC, an affiliate of New York Life Investments, is the Fund's
transfer, dividend disbursing and shareholder servicing agent pursuant to an
agreement between NYLIM Service Company LLC and the Trust. NYLIM Service Company
LLC has entered into an agreement with Boston Financial Data Services, Inc.
("BFDS") pursuant to which BFDS performs certain transfer agent services on
behalf of NYLIM Service Company LLC. Transfer agent expenses incurred by the
Fund for the six-month period ended April 30, 2010, were as follows:

<Table>

- -----------------------------------------------

</Table>




24    MainStay Cash Reserves Fund



(D) SMALL ACCOUNT FEE.  Shareholders with small accounts adversely impact the
cost of providing transfer agency services. In an effort to reduce total
transfer agency expenses, the Fund has implemented a small account fee on
certain types of accounts. Certain shareholders with an account balance of less
than $1,000 are charged an annual per account fee of $20 (assessed semi-
annually). These fees are included in transfer agent fees shown on the Statement
of Operations.

(E) CAPITAL.  At April 30, 2010, New York Life and its affiliates beneficially
held shares of the Fund with the following values and percentages of net assets
as follows:

- --------------------------------------------------

</Table>


(F) OTHER.  Pursuant to the Management Agreement, a portion of the cost of legal
services provided to the Fund by the Office of the General Counsel of New York
Life Investments is payable directly by the Fund. For the six-month period ended

NOTE 7--NEW ACCOUNTING PRONOUNCEMENT:

In January 2010, the Financial Accounting Standards Board ("FASB") issued
Accounting Standards Update ("ASU") No. 2010-06 "Improving Disclosures about
Fair Value Measurements". ASU 2010-06 requires reporting entities to make new
disclosures about amount and reasons for significant transfers in and out of
Level 1 and Level 2 fair value measurements and input and valuation techniques
used to measure fair value for both recurring and nonrecurring fair value
measurements that fall in either Level 2 or Level 3, and information on
purchased, sales, issuances, and settlements in the roll forward of activity in
Level 3 fair value measures. The new and revised disclosure requirements are
effective for interim and annual reporting periods beginning after December 15,
2009 except for the disclosures about purchased, sales, issuances, and
settlements in the roll forward of activity in Level 3 fair value measures,
which are effective for fiscal years beginning after December 15, 2010. As of
April 30, 2010, the Fund has adopted ASU 2010-06. The adoption of ASU 2010-06
has not impacted the amounts reported in the financial statements; however,
there are additional disclosures in the Portfolio of Investments.

     MESSAGE FROM THE PRESIDENT AND SEMIANNUAL REPORT

     Unaudited - April 30, 2010

MESSAGE FROM THE PRESIDENT

During the six months ended April 30, 2010, stock and bond markets generally
advanced, despite some volatility in January and February. Domestic small-cap
stocks were particularly strong, and U.S. stocks at all capitalization levels
provided double digit returns. Value stocks outpaced growth stocks for companies
of all sizes during the reporting period.

International stocks provided positive returns overall, but results varied
widely by country. Concerns about Greece's ability to meet its debt obligations
led many investors to abandon their holdings in Greece and question their
investments in several peripheral European nations where perceived risk had
increased. For the six-month reporting period, equities in the Far East
(including Japan) tended to be stronger than those in Europe.

The economic recovery in the United States continued. Real gross domestic
product advanced in the first quarter of 2010, though at a slower pace than in
the fourth quarter of 2009. The Federal Open Market Committee kept the targeted
federal funds rate at a historically low level throughout the reporting period,
which prompted many investors to leave the safety of U.S. Treasury securities in
search of higher yield.

In the high-yield bond market, lower-rated credits tended to be the strongest
performers. With investment-grade investors crossing into high-yield territory,
however, the highest-rated high-yield credits also saw strong demand. In the
municipal market, new-issue supply was reduced by government incentives that
encouraged municipal issuers to raise funds in the taxable market. In the
leveraged-loan market, new issuance strengthened, but extensive repayments
caused the market as a whole to contract.


Throughout the six-month reporting period, MainStay's portfolio managers sought
to make the most of market conditions within the investment strategies and risk
parameters of their respective Funds. While individual markets and Fund results
may vary, our pursuit of competitive returns over full market cycles has never
changed.

The information that follows provides a closer look
at the securities, strategies and market conditions that affected your MainStay
Fund(s) during the six months ended April 30, 2010. Of course, past performance
is no guarantee of future results. Even in a rising market, we believe that
maintaining a long-term perspective can be valuable. At MainStay, we believe
that in all markets, broad diversification, gradual allocation adjustments and
regular portfolio reviews can help guide you toward your long-range financial
goals.

We thank you for choosing MainStay Funds, and we look forward to serving your
investment needs for many years to come.

Sincerely,

/s/ STEPHEN P. FISHER

Stephen P. Fisher
President

1. Performance tables and graphs do not reflect the deduction of taxes that a
   shareholder would pay on distributions or Fund-share redemptions. Total
   returns reflect maximum applicable sales charges explained in this paragraph,
   change in share price, and reinvestment of dividend and capital gain
   distributions. The graphs assume an initial investment of $25,000 for Class A
   shares and $10,000 for all other classes and reflect the deduction of all
   sales charges that would have applied for the period of investment. Class A
   shares generally have a $25,000 minimum initial investment with no minimum
   subsequent purchase amount. For investors that, in the aggregate, have assets
   of $100,000 or more invested in any share classes of any of the MainStay
   Funds, the minimum initial investment is $15,000. Investor Class shares and
   Class A shares are sold with a maximum initial sales charge of 5.50% and an
   annual 12b-1 fee of 0.25%. Class B shares are sold with no initial sales
   charge, are subject to a contingent deferred sales charge ("CDSC") of up to
   5.00% if redeemed within the first six years of purchase, and have an annual
   12b-1 fee of 1.00%. Class C shares are sold with no initial sales charge, are
   subject to a CDSC of 1.00% if redeemed within one year of purchase, and have
   an annual 12b-1 fee of 1.00%. Class I shares are sold with no initial sales
   charge or CDSC, have no annual 12b-1 fee, and are generally available to
   corporate and institutional investors or individual investors with a minimum
   initial investment of $5 million. Performance figures reflect certain fee
   waivers and/or expense limitations, without which total returns may have been
   lower. For

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY CONSERVATIVE ALLOCATION FUND
(UNAUDITED)
- --------------------------------------------------------------------------------

The example below is intended to describe the fees and expenses borne by
shareholders during the six-month period from November 1, 2009, to April 30,
2010, and the impact of those costs on your investment.

EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, exchange fees, and sales charges (loads) on
purchases (as applicable), and (2) ongoing costs, including management fees,
distribution and/or service (12b-1) fees, and other Fund expenses (as
applicable). This example is intended to help you understand your ongoing costs
(in dollars) of investing in the Fund and to compare these costs with the
ongoing costs of investing in other mutual funds. The example is based on an
investment of $1,000 made at the beginning of the six-month period and held for
the entire period from November 1, 2009, to April 30, 2010.

This example illustrates your Fund's ongoing costs in two ways:

- - ACTUAL EXPENSES
The second and third data columns in the table below provide information about
actual account values and actual expenses. You may use the information in these
columns, together with the amount you invested, to estimate the expenses that
you paid during the six-months ended April 30, 2010. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number under the heading entitled "Expenses Paid
During Period" to estimate the expenses you paid on your account during this
period.

- - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The fourth and fifth data columns in the table below provide information about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense ratio and an assumed rate of return of 5% per year before expenses,
which is not the Fund's actual return. The hypothetical account values and
expenses may not be used to estimate the actual ending account balances or
expenses you paid for the six-month period shown. You may use this information
to compare the ongoing costs of investing in the Fund with the ongoing costs of
investing in other Funds. To do so, compare this 5% hypothetical example with
the 5% hypothetical examples that appear in the shareholder reports of the other
Funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as
redemption fees, if applicable, exchange fees, or sales charges (loads).
Therefore, the fourth and fifth data columns of the table are useful in
comparing ongoing costs only and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.

1. Expenses are equal to the Fund's annualized expense ratio of each class
   (0.50% for Investor Class, 0.42% for Class A, 1.25% for Class B and Class C
   and 0.17% for Class I) multiplied by the average account value over the
   period, divided by 365 and multiplied by 181 (to reflect the one-half year
   period). The table above represents the actual expenses incurred during the
   one-half year period. In addition to the fees and expenses which the Fund
   bears directly, the Fund indirectly bears a pro rata share of the fees and
   expenses of the Underlying Funds in which it invests. Such indirect expenses
   are not included in the above-reported expense figures.

8    MainStay Conservative Allocation Fund



PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

QUESTIONS ANSWERED BY PORTFOLIO MANAGERS TONY ELAVIA AND JONATHAN SWANEY OF
MADISON SQUARE INVESTORS LLC, THE FUND'S SUBADVISOR.

HOW DID MAINSTAY CONSERVATIVE ALLOCATION FUND PERFORM RELATIVE TO ITS PEERS AND
ITS BENCHMARK DURING THE SIX MONTHS ENDED APRIL 30, 2010?

Excluding all sales charges, MainStay Conservative Allocation Fund returned
7.70% for Investor Class shares, 7.64% for Class A shares and 7.34% for Class B
and Class C shares for the six months ended April 30, 2010. Over the same
period, the Fund's Class I shares returned 7.83%. All share classes outperformed
the 7.24% return of the average Lipper(1) mixed-asset target allocation
conservative fund for the six months ended April 30, 2010. All share classes
underperformed the 15.66% return of the S&P 500(R) Index(2) for the same six-
month period. The S&P 500(R) Index is the Fund's broad-based securities-market
index. See pages 5 and 6 for Fund returns with sales charges.

WHAT FACTORS CONTRIBUTED TO THE FUND'S RELATIVE PERFORMANCE DURING THE REPORTING
PERIOD?

The Fund invests in other mutual funds referred to as Underlying Funds. The
Underlying Funds may invest in fixed-income securities or in domestic or
international stocks at various capitalization levels. The Fund's primary
benchmark, on the other hand, consists entirely of U.S. large-cap stocks. These
asset-class differences accounted for much of the Fund's underperformance of the
S&P 500(R) Index. Even with the Fund's asset-allocation targets taken into
account, however, performance was moderately below our expectations.
Disappointing results from several Underlying Funds, particularly those that use
quantitative stock selection, contributed to the shortfall.
The Fund also had negative beta exposure (or lower volatility than the market as
a whole) in a period when the stock market was rising. In addition, the Fund
suffered from a slight bias toward growth-
oriented stocks in a period when value stocks were in favor. Despite these
shortcomings, the Fund outperformed its average Lipper peer fund.

DURING THE REPORTING PERIOD, HOW DID YOU DETERMINE THE FUND'S ALLOCATIONS AMONG
THE UNDERLYING FUNDS?

In managing the Fund, we considered a variety of information, including
portfolio-level characteristics of the Underlying Funds, such as capitalization,
style biases and sector exposures. We also examined the attributes of the
Underlying Funds' holdings, such
as valuation metrics, earnings data and technical indicators. Finally, we
evaluated the historical success of the portfolio managers responsible for the
Underly-
ing Funds. In general, we sought Underlying Equity Funds that had a track record
of capable portfolio management, that occupied attractively valued market
segments and that invested in companies with fairly priced securities and strong
price and earnings momentum. During the reporting period, these techniques were
generally unsuccessful, as they steered the Fund into Underlying Funds that
collectively underperformed the S&P 500(R) Index after adjusting for Underlying
Fund expenses and strategic allocation policy.

Underlying Fixed Income Funds were selected based upon the type and country of
issuance of the securities in which they invested, the average credit quality of
those securities and their duration.(3)

It is usually difficult to identify any single factor that had a
disproportionate effect on the Fund's relative performance, but during the
reporting period, one theme had a distinctive impact. We tilted the Fund toward
Underlying Funds that prized earnings stability, because higher-quality stocks
with stable earnings have historically been rewarded with higher returns than
lower-quality stocks with earnings that are less stable. Unfortunately, when the
global equity mar-
kets turned positive in the spring of 2009, investors aggressively bought the
riskiest and lowest-quality securities in anticipation that these securities
would benefit most from a recovery. This trend persisted throughout the
reporting period, and stocks with negative earnings and cash flows were among
the best performers. This so-called junk rally served as a significant drag on
the Fund's relative performance during the reporting period.

DID YOU MAKE ANY SIGNIFICANT CHANGES IN THE FUND'S ALLOCATIONS DURING THE
REPORTING PERIOD?

The most significant change we made during the reporting period was a gradual,
protracted shift away from large-cap growth-oriented Underlying Funds toward
Underlying Funds with a more neutral style and capitalization focus.
Specifically, we reduced
the Fund's allocations to MainStay Large Cap Growth Fund, MainStay Growth Equity
Fund and MainStay 130/30 Growth Fund and increased the Fund's allocations to
MainStay Epoch U.S. All Cap Fund and, to
a lesser degree, to MainStay 130/30 Core Fund. This shift had a positive impact
on the Fund's perfor-mance, as value-oriented smaller-capitalization stocks
outpaced growth-oriented larger-cap stocks as the

3. Duration is a measure of the price sensitivity of a fixed-income investment
   to changes in interest rates. Duration is expressed as a number of years and
   is considered a more accurate sensitivity gauge than average maturity.

reporting period progressed. We have substantially reduced the Fund's exposure
to growth-oriented stocks over the past two and a half years. At the end of the
current reporting period, the Fund was evenly positioned between growth and
value.

During the reporting period, the Fund initiated new positions in MainStay Epoch
Global Choice Fund
and MainStay Convertible Fund. We chose MainStay Epoch Global Choice Fund to
further diversify the Fund across management strategies and to enhance the
Fund's exposure to desirable cash flow metrics. MainStay Convertible Fund was
chosen to increase the Fund's overall responsiveness to movements in the equity
market while incrementally lowering the Fund's average credit quality and
duration.

DURING THE REPORTING PERIOD, WHICH UNDERLYING EQUITY FUND POSITIONS HAD THE
HIGHEST TOTAL RETURNS AND WHICH HAD THE LOWEST TOTAL RETURNS?

MainStay U.S. Small Cap Fund and MainStay Epoch U.S. All Cap Fund generated the
highest total returns among the Underlying Equity Funds in which the Fund
invested, as these Underlying Funds reached furthest down the capitalization
spectrum. The worst returns came from Underlying Funds that invest abroad,
namely MainStay ICAP International Fund and MainStay 130/30 International Fund.
These Underlying Equity Funds were hampered not only by comparatively weak
overseas returns in local currencies but also by a strengthening U.S. dollar.

DURING THE REPORTING PERIOD, WHICH UNDERLYING EQUITY FUNDS MADE THE STRONGEST
CONTRIBUTIONS TO THE FUND'S ABSOLUTE PERFORMANCE AND WHICH UNDERLYING EQUITY
FUNDS DETRACTED THE MOST?

Among the Underlying Equity Funds in which the Fund invested, MainStay MAP Fund
and MainStay Large Cap Growth Fund were the strongest contributors to the Fund's
absolute performance.

During the reporting period, no Underlying Equity Funds in which the Fund
invested provided negative returns. The weakest contributions to the Fund's
performance came from two of its smallest positions, MainStay S&P 500 Index Fund
and MainStay Epoch Global Choice Fund.

WHAT FACTORS INFLUENCED PERFORMANCE IN THE FIXED-INCOME PORTION OF THE FUND
DURING THE SIX MONTHS ENDED APRIL 30, 2010?

U.S. Treasury yields were largely unchanged over
the course of the reporting period. Signs of economic strength, improving
corporate profitability and a large supply of new issuance threatened to push
rates higher. These factors, however, were offset by concerns about corporate
and sovereign default risk (holding company Dubai World and Greece were notable
examples) and by questions about the sustainability of the economic recovery.
Lower-quality fixed-income securities generally outperformed higher-quality
fixed-income securities as credit spreads(4) narrowed, driving bond prices
higher.

HOW DID THE FUND ALLOCATE ASSETS AMONG THE UNDERLYING FIXED INCOME FUNDS DURING
THE REPORTING PERIOD?

In anticipation that Treasury rates would ultimately rise and that credit
spreads would continue to narrow from the wider-than-normal levels we had
observed, we shortened the Fund's duration and reestablished
a bias toward lower-quality instruments. We implemented these strategies
primarily by increasing the Fund's holdings in MainStay Floating Rate Fund,
MainStay High Yield Opportunities Fund and MainStay High Yield Corporate Bond
Fund.

DURING THE REPORTING PERIOD, WHICH UNDERLYING FIXED INCOME FUNDS HAD THE
STRONGEST ABSOLUTE PERFORMANCE AND WHICH ONES DETRACTED FROM THE FUND'S ABSOLUTE
PERFORMANCE?

The Fund's best-performing Underlying Fixed Income Fund holdings were MainStay
High Yield Opportunities Fund and MainStay High Yield Corporate Bond Fund, both
of which benefited from the contraction in credit spreads that accompanied the
economic recovery. MainStay Indexed Bond Fund and Main-Stay Intermediate Term
Bond Fund were the worst-performing Underlying Fixed Income Funds, as both
invest in higher-quality debt instruments. Still, both of these Underlying Fixed

1. Performance tables and graphs do not reflect the deduction of taxes that a
   shareholder would pay on distributions or Fund-share redemptions. Total
   returns reflect maximum applicable sales charges explained in this paragraph,
   change in share price, and reinvestment of dividend and capital gain
   distributions. The graphs assume an initial investment of $25,000 for Class A
   shares and $10,000 for all other classes and reflect the deduction of all
   sales charges that would have applied for the period of investment. Class A
   shares generally have a $25,000 minimum initial investment with no minimum
   subsequent purchase amount. For investors that, in the aggregate, have assets
   of $100,000 or more invested in any share classes of any of the MainStay
   Funds, the minimum initial investment is $15,000. Investor Class shares and
   Class A shares are sold with a maximum initial sales charge of 5.50% and an
   annual 12b-1 fee of 0.25%. Class B shares are sold with no initial sales
   charge, are subject to a contingent deferred sales charge ("CDSC") of up to
   5.00% if redeemed within the first six years of purchase, and have an annual
   12b-1 fee of 1.00%. Class C shares are sold with no initial sales charge, are
   subject to a CDSC of 1.00% if redeemed within one year of purchase, and have
   an annual 12b-1 fee of 1.00%. Class I shares are sold with no initial sales
   charge or CDSC, have no annual 12b-1 fee, and are generally available to
   corporate and institutional investors or individual investors with a minimum
   initial investment of $5 million. Performance figures reflect certain fee
   waivers and/or expense limitations, without which total returns may have been
   lower. For information on current fee waivers and/or expense limitations,
   please refer to the notes to the financial statements.

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY GROWTH ALLOCATION FUND
(UNAUDITED)
- --------------------------------------------------------------------------------

The example below is intended to describe the fees and expenses borne by
shareholders during the six-month period from November 1, 2009, to April 30,
2010, and the impact of those costs on your investment.

EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, exchange fees, and sales charges (loads) on
purchases (as applicable), and (2) ongoing costs, including management fees,
distribution and/or service (12b-1) fees, and other Fund expenses (as
applicable). This example is intended to help you understand your ongoing costs
(in dollars) of investing in the Fund and to compare these costs with the
ongoing costs of investing in other mutual funds. The example is based on an
investment of $1,000 made at the beginning of the six-month period and held for
the entire period from November 1, 2009, to April 30, 2010.

This example illustrates your Fund's ongoing costs in two ways:

- - ACTUAL EXPENSES
The second and third data columns in the table below provide information about
actual account values and actual expenses. You may use the information in these
columns, together with the amount you invested, to estimate the expenses that
you paid during the six-months ended April 30, 2010. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number under the heading entitled "Expenses Paid
During Period" to estimate the expenses you paid on your account during this
period.

- - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The fourth and fifth data columns in the table below provide information about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense ratio and an assumed rate of return of 5% per year before expenses,
which is not the Fund's actual return. The hypothetical account values and
expenses may not be used to estimate the actual ending account balances or
expenses you paid for the six-month period shown. You may use this information
to compare the ongoing costs of investing in the Fund with the ongoing costs of
investing in other Funds. To do so, compare this 5% hypothetical example with
the 5% hypothetical examples that appear in the shareholder reports of the other
Funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as
redemption fees, if applicable, exchange fees, or sales charges (loads).
Therefore, the fourth and fifth data columns of the table are useful in
comparing ongoing costs only and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.

1. Expenses are equal to the Fund's annualized expense ratio of each class
   (0.50% for Investor Class, 0.47% for Class A, 1.25% for Class B and Class C
   and 0.22% for Class I) multiplied by the average account value over the
   period, divided by 365 and multiplied by 181 (to reflect the one-half year
   period). The table above represents the actual expenses incurred during the
   one-half year period. In addition to the fees and expenses which the Fund
   bears directly, the Fund indirectly bears a pro rata share of the fees and
   expenses of the Underlying Funds in which it invests. Such indirect expenses
   are not included in the above-reported expense figures.

HOW DID MAINSTAY GROWTH ALLOCATION FUND PERFORM RELATIVE TO ITS PEERS AND ITS
BENCHMARK DURING THE SIX MONTHS ENDED APRIL 30, 2010?

Excluding all sales charges, MainStay Growth Allocation Fund returned 12.19% for
Investor Class shares, 12.22% for Class A shares, 11.79% for Class B shares and
11.65% for Class C shares for the six months ended April 30, 2010. Over the same
period, the Fund's Class I shares returned 12.31%. All share classes
underperformed the 16.13% return of the average Lipper(1) multi-cap core fund
for the six months ended April 30, 2010. All share classes also underperformed
the 15.66% return of the S&P 500(R) Index(2) for the same six-month period. The
S&P 500(R) Index is the Fund's broad-based securities-market index. See pages 19
and 20 for Fund returns with sales charges.

WHAT FACTORS CONTRIBUTED TO THE FUND'S RELATIVE PERFORMANCE DURING THE REPORTING
PERIOD?

The Fund invests in other mutual funds referred to as Underlying Funds. The
Underlying Funds may invest in domestic or international stocks at various
capitalization levels. The Fund's primary benchmark, on the other hand, consists
entirely of large-cap U.S. stocks. These asset-class differences accounted for
much of the Fund's underperformance of the S&P 500(R) Index. Even with the
Fund's asset-allocation targets taken into account, however, performance was
substantially below our expectations. Disappointing results from several
Underlying Funds, particularly those that use quantitative stock selection,
detracted from the Fund's performance relative to the S&P 500(R) Index and the
average Lipper peer fund. The Fund also had negative beta exposure (or lower
volatility than the market as a whole) in a period when the stock market was
rising. In addition, the Fund suffered from a slight bias toward growth-oriented
stocks in a period when value stocks were in favor.

DURING THE REPORTING PERIOD, HOW DID YOU DETERMINE THE FUND'S ALLOCATIONS AMONG
THE UNDERLYING FUNDS?

In managing the Fund, we considered a variety of information, including
portfolio-level characteristics of the Underlying Funds, such as capitalization,
style biases and sector exposures. We also examined the attributes of the
Underlying Funds' holdings, such as valuation metrics, earnings data and
technical indicators. Finally, we evaluated the historical success of the
portfolio managers responsible for the Underly-
ing Funds. In general, we sought Underlying Equity Funds that had a track record
of capable portfolio management, that occupied attractively valued market
segments and that invested in companies with fairly priced securities and strong
price and earnings momentum. During the reporting period, these techniques were
generally unsuccessful, as they steered the Fund into investments in Underlying
Funds that collectively underperformed the S&P 500(R) Index after adjusting for
Underlying Fund expenses and strategic allocation policy.

It is usually difficult to identify any single factor that had a
disproportionate effect on the Fund's relative performance, but during the
reporting period, one theme had a distinctive impact. We tilted the Fund toward
Underlying Funds that prized earnings stability, because higher-quality stocks
with stable earnings have historically been rewarded with higher returns than
lower-quality stocks with earnings that are less stable. Unfortunately, when the
global equity mar-
kets turned positive in the spring of 2009, investors aggressively bought the
riskiest and lowest-quality securities in anticipation that these securities
would benefit most from a recovery. This trend persisted throughout the
reporting period, and stocks with negative earnings and cash flows were among
the best performers. This so-called junk rally served as a significant drag on
the Fund's relative performance during the reporting period.

DID YOU MAKE ANY SIGNIFICANT CHANGES IN THE FUND'S ALLOCATIONS DURING THE
REPORTING PERIOD?

The most significant change we made during the reporting period was a gradual,
protracted shift away from large-cap growth-oriented Underlying Funds toward
Underlying Funds with a more neutral style and capitalization focus.
Specifically, we reduced
the Fund's allocations to MainStay Large Cap Growth Fund, MainStay Growth Equity
Fund and MainStay 130/30 Growth Fund and increased the Fund's allocations to
MainStay Epoch U.S. All Cap Fund and, to
a lesser degree, to MainStay 130/30 Core Fund. This shift had a positive impact
on the Fund's performance, as value-oriented smaller-capitalization stocks
outpaced growth-oriented larger-cap stocks as the reporting period progressed.
We have substantially reduced the Fund's exposure to growth-oriented stocks over
the past two and a half years. At the end of the current reporting period, the
Fund was evenly positioned between growth and value.

During the reporting period, the Fund initiated a new position in MainStay Epoch
Global Choice Fund. We chose this Underlying Fund to further diversify the

Fund across management strategies and to enhance the Fund's exposure to
desirable cash flow metrics.

DURING THE REPORTING PERIOD, WHICH UNDERLYING EQUITY FUND POSITIONS HAD THE
HIGHEST TOTAL RETURNS AND WHICH HAD THE LOWEST TOTAL RETURNS?

MainStay U.S. Small Cap Fund and MainStay Epoch U.S. All Cap Fund generated the
highest total returns among the Underlying Equity Funds in which the Fund
invested, as these Underlying Funds reached furthest down the capitalization
spectrum. The worst returns came from Underlying Funds that invest abroad,
namely MainStay ICAP International Fund and MainStay 130/30 International Fund.
These Underlying Equity Funds were hampered not only by comparatively weak
overseas returns in local currencies but also by a strengthening U.S. dollar.

DURING THE REPORTING PERIOD, WHICH UNDERLYING EQUITY FUNDS MADE THE STRONGEST
CONTRIBUTIONS TO THE FUND'S ABSOLUTE PERFORMANCE AND WHICH UNDERLYING EQUITY
FUNDS DETRACTED THE MOST?

Among the Underlying Equity Funds in which the Fund invested, MainStay MAP Fund
and MainStay Growth Equity Fund were the strongest contributors to the Fund's
absolute performance.

During the reporting period, no Underlying Equity Funds in which the Fund
invested provided negative returns. The weakest contributions to the Fund's
performance came from two of its smallest positions, MainStay S&P 500 Index Fund
and MainStay Epoch Global Choice Fund.

1. Performance tables and graphs do not reflect the deduction of taxes that a
   shareholder would pay on distributions or Fund-share redemptions. Total
   returns reflect maximum applicable sales charges explained in this paragraph,
   change in share price, and reinvestment of dividend and capital gain
   distributions. The graphs assume an initial investment of $25,000 for Class A
   shares and $10,000 for all other classes and reflect the deduction of all
   sales charges that would have applied for the period of investment. Class A
   shares generally have a $25,000 minimum initial investment with no minimum
   subsequent purchase amount. For investors that, in the aggregate, have assets
   of $100,000 or more invested in any share classes of any of the MainStay
   Funds, the minimum initial investment is $15,000. Investor Class shares and
   Class A shares are sold with a maximum initial sales charge of 5.50% and an
   annual 12b-1 fee of 0.25%. Class B shares are sold with no initial sales
   charge, are subject to a contingent deferred sales charge ("CDSC") of up to
   5.00% if redeemed within the first six years of purchase, and have an annual
   12b-1 fee of 1.00%. Class C shares are sold with no initial sales charge, are
   subject to a CDSC of 1.00% if redeemed within one year of purchase, and have
   an annual 12b-1 fee of 1.00%. Class I  shares are sold with no initial sales
   charge or CDSC, have no annual 12b-1 fee, and are generally available to
   corporate and institutional investors or individual investors with a minimum
   initial investment of $5 million. Performance figures reflect certain fee

34    MainStay Moderate Allocation Fund



COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY MODERATE ALLOCATION FUND
(UNAUDITED)
- --------------------------------------------------------------------------------

The example below is intended to describe the fees and expenses borne by
shareholders during the six-month period from November 1, 2009, to April 30,
2010, and the impact of those costs on your investment.

EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, exchange fees, and sales charges (loads) on
purchases (as applicable), and (2) ongoing costs, including management fees,
distribution and/or service (12b-1) fees, and other Fund expenses (as
applicable). This example is intended to help you understand your ongoing costs
(in dollars) of investing in the Fund and to compare these costs with the
ongoing costs of investing in other mutual funds. The example is based on an
investment of $1,000 made at the beginning of the six-month period and held for
the entire period from November 1, 2009, to April 30, 2010.

This example illustrates your Fund's ongoing costs in two ways:

- - ACTUAL EXPENSES
The second and third data columns in the table below provide information about
actual account values and actual expenses. You may use the information in these
columns, together with the amount you invested, to estimate the expenses that
you paid during the six-months ended April 30, 2010. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number under the heading entitled "Expenses Paid
During Period" to estimate the expenses you paid on your account during this
period.

- - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The fourth and fifth data columns in the table below provide information about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense ratio and an assumed rate of return of 5% per year before expenses,
which is not the Fund's actual return. The hypothetical account values and
expenses may not be used to estimate the actual ending account balances or
expenses you paid for the six-month period shown. You may use this information
to compare the ongoing costs of investing in the Fund with the ongoing costs of
investing in other Funds. To do so, compare this 5% hypothetical example with
the 5% hypothetical examples that appear in the shareholder reports of the other
Funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as
redemption fees, if applicable, exchange fees, or sales charges (loads).
Therefore, the fourth and fifth data columns of the table are useful in
comparing ongoing costs only and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.

1. Expenses are equal to the Fund's annualized expense ratio of each class
   (0.50% for Investor Class, 0.39% for Class A, 1.25% for Class B and Class C
   and 0.14% for Class I) multiplied by the average account value over the
   period, divided by 365 and multiplied by 181 (to reflect the one-half year
   period). The table above represents the actual expenses incurred during the
   one-half year period. In addition to the fees and expenses which the Fund
   bears directly, the Fund indirectly bears a pro rata share of the fees and
   expenses of the Underlying Funds in which it invests. Such indirect expenses
   are not included in the above-reported expense figures.

36    MainStay Moderate Allocation Fund



PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

QUESTIONS ANSWERED BY PORTFOLIO MANAGERS TONY ELAVIA AND JONATHAN SWANEY OF
MADISON SQUARE INVESTORS LLC, THE FUND'S SUBADVISOR.

HOW DID MAINSTAY MODERATE ALLOCATION FUND PERFORM RELATIVE TO ITS PEERS AND ITS
BENCHMARK DURING THE SIX MONTHS ENDED APRIL 30, 2010?

Excluding all sales charges, MainStay Moderate Allocation Fund returned 8.97%
for Investor Class shares, 9.12% for Class A shares, 8.69% for Class B shares
and 8.67% for Class C shares for the six months ended April 30, 2010. Over the
same period, the Fund's Class I shares returned 9.32%. All share classes
underperformed the 9.53% return of the average Lipper(1) mixed-asset target
allocation moderate fund for the six months ended April 30, 2010. All share
classes also underperformed the 15.66% return of the S&P 500(R) Index(2) for the
same six-month period. The S&P 500(R) Index is the Fund's broad-based
securities-market index. See pages 33 and 34 for Fund returns with sales
charges.

WHAT FACTORS CONTRIBUTED TO THE FUND'S RELATIVE PERFORMANCE DURING THE REPORTING
PERIOD?

The Fund invests in other mutual funds referred to as Underlying Funds. The
Underlying Funds may invest in fixed-income securities or in domestic or
international stocks at various capitalization levels. The Fund's primary
benchmark, on the other hand, consists entirely of U.S. large-cap stocks. These
asset-class differences accounted for much of the Fund's underperformance of the
S&P 500(R) Index. Even with the Fund's asset-allocation targets taken into
account, however, performance was moderately below our expectations.
Disappointing results from several Underlying Funds, particularly those that use
quantitative stock selection, detracted from the Fund's performance relative to
the S&P 500(R) Index and the average Lipper peer fund. The Fund also had
negative beta exposure (or lower volatility than the market as a whole) in a
period when the stock market was rising. In addition, the Fund suffered from a
slight bias toward growth-oriented stocks in a period when value stocks were in
favor.

DURING THE REPORTING PERIOD, HOW DID YOU DETERMINE THE FUND'S ALLOCATIONS AMONG
THE UNDERLYING FUNDS?

In managing the Fund, we considered a variety of information, including
portfolio-level characteristics of the Underlying Funds, such as capitalization,
style biases and sector exposures. We also examined the attributes of the
Underlying Funds' holdings, such
as valuation metrics, earnings data and technical indicators. Finally, we
evaluated the historical success of the portfolio managers responsible for the
Underlying Funds. In general, we sought Underlying Equity Funds that had a track
record of capable portfolio management, that occupied attractively valued market
segments and that invested in companies with fairly priced securities and strong
price and earnings momentum. During the reporting period, these techniques were
generally unsuccessful, as they steered the Fund into Underlying Funds that
collectively underperformed the S&P 500(R) Index after adjusting for Underlying
Fund expenses and strategic allocation policy.

Underlying Fixed Income Funds were selected based upon the type and country of
issuance of the securities in which they invested, the average credit quality of
those securities and their duration.(3)

It is usually difficult to identify any single factor that had a
disproportionate effect on the Fund's relative performance, but during the
reporting period, one theme had a distinctive impact. We tilted the Fund toward
Underlying Funds that prized earnings stability, because higher-quality stocks
with stable earnings have historically been rewarded with higher returns than
lower-quality stocks with earnings that are less stable. Unfortunately, when the
global equity mar-
kets turned positive in the spring of 2009, investors aggressively bought the
riskiest and lowest-quality securities in anticipation that these securities
would benefit most from a recovery. This trend persisted throughout the
reporting period, and stocks with negative earnings and cash flows were among
the best performers. This so-called junk rally served as
a significant drag on the Fund's relative performance during the reporting
period.

DID YOU MAKE ANY SIGNIFICANT CHANGES IN THE FUND'S ALLOCATIONS DURING THE
REPORTING PERIOD?

The most significant change we made during the reporting period was a gradual,
protracted shift away from large-cap growth-oriented Underlying Funds toward
Underlying Funds with a more neutral style and capitalization focus.
Specifically, we reduced the Fund's allocations to MainStay Large Cap Growth
Fund, MainStay Growth Equity Fund and MainStay 130/30 Growth Fund and increased
the Fund's allocations to MainStay Epoch U.S. All Cap Fund and, to a lesser
degree, to MainStay 130/30 Core Fund. This shift had a positive impact on the
Fund's performance, as value-oriented smaller-capitalization stocks

2. See footnote on page 34 for more information on the S&P 500(R) Index.
3. Duration is a measure of the price sensitivity of a fixed-income investment
   to changes in interest rates. Duration is expressed as a number of years and
   is considered a more accurate sensitivity gauge than average maturity.

outpaced growth-oriented larger-cap stocks as the reporting period progressed.
We have substantially reduced the Fund's exposure to growth-oriented stocks over
the past two and a half years. At the end of the current reporting period, the
Fund was evenly positioned between growth and value.

During the reporting period, the Fund initiated new positions in MainStay Epoch
Global Choice Fund
and MainStay Convertible Fund. We chose MainStay Epoch Global Choice Fund to
further diversify the Fund across management strategies and to enhance the
Fund's exposure to desirable cash flow metrics. MainStay Convertible Fund was
chosen to increase the Fund's overall responsiveness to movements in the equity
market while incrementally lowering the Fund's average credit quality and
duration.

DURING THE REPORTING PERIOD, WHICH UNDERLYING EQUITY FUND POSITIONS HAD THE
HIGHEST TOTAL RETURNS AND WHICH HAD THE LOWEST TOTAL RETURNS?

MainStay U.S. Small Cap Fund and MainStay Epoch U.S. All Cap Fund generated the
highest total returns among the Underlying Equity Funds in which the Fund
invested, as these Underlying Funds reached furthest down the capitalization
spectrum. The worst returns came from Underlying Funds that invest abroad,
namely MainStay ICAP International Fund and MainStay 130/30 International Fund.
These Underlying Equity Funds were hampered not only by comparatively weak
overseas returns in local currencies but also by a strengthening U.S. dollar.

DURING THE REPORTING PERIOD, WHICH UNDERLYING EQUITY FUNDS MADE THE STRONGEST
CONTRIBUTIONS TO THE FUND'S ABSOLUTE PERFORMANCE AND WHICH UNDERLYING EQUITY
FUNDS DETRACTED THE MOST?

Among the Underlying Equity Funds in which the Fund invested, MainStay MAP Fund
and MainStay Growth Equity Fund were the strongest contributors to the Fund's
absolute performance.

During the reporting period, no Underlying Equity Funds in which the Fund
invested provided negative returns. The weakest contributions to the Fund's
performance came from two of its smallest positions, MainStay S&P 500 Index Fund
and MainStay Epoch Global Choice Fund.

WHAT FACTORS INFLUENCED PERFORMANCE IN THE FIXED-INCOME PORTION OF THE FUND
DURING THE SIX MONTHS ENDED APRIL 30, 2010?

U.S. Treasury yields were largely unchanged over
the course of the reporting period. Signs of economic strength, improving
corporate profitability and a large supply of new issuance threatened to push
rates higher. These factors, however, were offset by concerns about corporate
and sovereign default risk (holding company Dubai World and Greece were notable
examples) and by questions about the sustainability of the economic recovery.
Lower-quality fixed-income securities generally outperformed higher-quality
fixed-income securities as credit spreads(4) narrowed, driving bond prices
higher.

HOW DID THE FUND ALLOCATE ASSETS AMONG THE UNDERLYING FIXED INCOME FUNDS DURING
THE REPORTING PERIOD?

In anticipation that Treasury rates would ultimately rise and that credit
spreads would continue to narrow from the wider-than-normal levels we had
observed, we shortened the Fund's duration and reestablished
a bias toward lower-quality instruments. We implemented these strategies
primarily by increasing the Fund's holdings in MainStay Floating Rate Fund,
MainStay High Yield Opportunities Fund and MainStay High Yield Corporate Bond
Fund.

DURING THE REPORTING PERIOD, WHICH UNDERLYING FIXED INCOME FUNDS HAD THE
STRONGEST ABSOLUTE PERFORMANCE AND WHICH ONES DETRACTED FROM THE FUND'S ABSOLUTE
PERFORMANCE?

The Fund's best-performing Underlying Fixed Income Fund holdings were MainStay
High Yield Opportunities Fund and MainStay High Yield Corporate Bond Fund, both
of which benefited from the contraction in credit spreads that accompanied the
economic recovery. MainStay Indexed Bond Fund and Main-
Stay Intermediate Term Bond Fund were the worst-performing Underlying Fixed
Income Funds, as both invest in higher-quality debt instruments. Still, both of
these Underlying Fixed Income Funds posted positive results during the reporting
period.


4. The terms "credit spread" and "yield spread" may refer to the difference in
   yield between a security or type of security and comparable U.S. Treasury
   issues. The terms may also refer to the difference in yield between two
   specific securities or types of securities at a given time.

1. Performance tables and graphs do not reflect the deduction of taxes that a
   shareholder would pay on distributions or Fund-share redemptions. Total
   returns reflect maximum applicable sales charges explained in this paragraph,
   change in share price, and reinvestment of dividend and capital gain
   distributions. The graphs assume an initial investment of $25,000 for Class A
   shares and $10,000 for all other classes and reflect the deduction of all
   sales charges that would have applied for the period of investment. Class A
   shares generally have a $25,000 minimum initial investment with no minimum
   subsequent purchase amount. For investors that, in the aggregate, have assets
   of $100,000 or more invested in any share classes of any of the MainStay
   Funds, the minimum initial investment is $15,000. Investor Class shares and
   Class A shares are sold with a maximum initial sales charge of 5.50% and an
   annual 12b-1 fee of 0.25%. Class B shares are sold with no initial sales
   charge, are subject to a contingent deferred sales charge ("CDSC") of up to
   5.00% if redeemed within the first six years of purchase, and have an annual
   12b-1 fee of 1.00%. Class C shares are sold with no initial sales charge, are
   subject to a CDSC of 1.00% if redeemed within one year of purchase, and have
   an annual 12b-1 fee of 1.00%. Class I shares are sold with no initial sales
   charge or CDSC, have no annual 12b-1 fee, and are generally available

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY MODERATE GROWTH ALLOCATION
FUND (UNAUDITED)
- --------------------------------------------------------------------------------

The example below is intended to describe the fees and expenses borne by
shareholders during the six-month period from November 1, 2009, to April 30,
2010, and the impact of those costs on your investment.

EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, exchange fees, and sales charges (loads) on
purchases (as applicable), and (2) ongoing costs, including management fees,
distribution and/or service (12b-1) fees, and other Fund expenses (as
applicable). This example is intended to help you understand your ongoing costs
(in dollars) of investing in the Fund and to compare these costs with the
ongoing costs of investing in other mutual funds. The example is based on an
investment of $1,000 made at the beginning of the six-month period and held for
the entire period from November 1, 2009, to April 30, 2010.

This example illustrates your Fund's ongoing costs in two ways:

- - ACTUAL EXPENSES
The second and third data columns in the table below provide information about
actual account values and actual expenses. You may use the information in these
columns, together with the amount you invested, to estimate the expenses that
you paid during the six-months ended April 30, 2010. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number under the heading entitled "Expenses Paid
During Period" to estimate the expenses you paid on your account during this
period.

- - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The fourth and fifth data columns in the table below provide information about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense ratio and an assumed rate of return of 5% per year before expenses,
which is not the Fund's actual return. The hypothetical account values and
expenses may not be used to estimate the actual ending account balances or
expenses you paid for the six-month period shown. You may use this information
to compare the ongoing costs of investing in the Fund with the ongoing costs of
investing in other Funds. To do so, compare this 5% hypothetical example with
the 5% hypothetical examples that appear in the shareholder reports of the other
Funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as
redemption fees, if applicable, exchange fees, or sales charges (loads).
Therefore, the fourth and fifth data columns of the table are useful in
comparing ongoing costs only and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.

1. Expenses are equal to the Fund's annualized expense ratio of each class
   (0.50% for Investor Class, 0.41% for Class A, 1.25% for Class B and Class C
   and 0.16% for Class I) multiplied by the average account value over the
   period, divided by 365 and multiplied by 181 (to reflect the one-half year
   period). The table above represents the actual expenses incurred during the
   one-half year period. In addition to the fees and expenses which the Fund
   bears directly, the Fund indirectly bears a pro rata share of the fees and
   expenses of the Underlying Funds in which it invests. Such indirect expenses
   are not included in the above-reported expense figures.

50    MainStay Moderate Growth Allocation Fund



PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

QUESTIONS ANSWERED BY PORTFOLIO MANAGERS TONY ELAVIA AND JONATHAN SWANEY OF
MADISON SQUARE INVESTORS LLC, THE FUND'S SUBADVISOR.

HOW DID MAINSTAY MODERATE GROWTH ALLOCATION FUND PERFORM RELATIVE TO ITS PEERS
AND ITS BENCHMARK DURING THE SIX MONTHS ENDED APRIL 30, 2010?

Excluding all sales charges, MainStay Moderate Growth Allocation Fund returned
11.11% for Investor Class shares, 11.16% for Class A shares, 10.67% for Class B
shares and 10.66% for Class C shares for the six months ended April 30, 2010.
Over the same period, the Fund's Class I shares returned 11.19%. Investor Class,
Class A and Class I shares outperformed--and Class B and Class C shares
underperformed--the 11.01% return of the average Lipper(1) mixed-asset target
allocation growth fund for the six months ended April 30, 2010. All share
classes underperformed the 15.66% return of the S&P 500(R) Index(2) for the same
six-month period. The S&P 500(R) Index is the Fund's broad-based securities-
market index. See pages 47 and 48 for Fund returns with sales charges.

WHAT FACTORS CONTRIBUTED TO THE FUND'S RELATIVE PERFORMANCE DURING THE REPORTING
PERIOD?

The Fund invests in other mutual funds referred to as Underlying Funds. The
Underlying Funds may invest in fixed-income securities or in domestic or
international stocks at various capitalization levels. The Fund's primary
benchmark, on the other hand, consists entirely of U.S. large-cap stocks. These
asset-class differences accounted for much of the Fund's underperformance of the
S&P 500(R) Index. Even with the Fund's asset-allocation targets taken into
account, however, performance was moderately below our expectations.
Disappointing results from several Underlying Funds, particularly those that use
quantitative stock selection, contributed to the shortfall. The Fund also had
negative beta exposure (or lower volatility than the market as a whole) in a
period when the stock market was rising. In addition, the Fund suffered from a
slight bias toward growth-oriented stocks in a period when value stocks were in
favor. Despite these shortcomings, three of the Fund's share classes managed to
outperform the average Lipper peer fund.

DURING THE REPORTING PERIOD, HOW DID YOU DETERMINE THE FUND'S ALLOCATIONS AMONG
THE UNDERLYING FUNDS?

In managing the Fund, we considered a variety of information, including
portfolio-level characteristics of the Underlying Funds, such as capitalization,
style biases and sector exposures. We also examined the attributes of the
Underlying Funds' holdings, such as valuation metrics, earnings data and
technical indicators. Finally, we evaluated the historical success of the
portfolio managers responsible for the Underlying Funds. In general, we sought
Underlying Equity Funds that had a track record of capable portfolio management,
that occupied attractively valued market segments and that invested in companies
with fairly priced securities and strong price and earnings momentum. During the
reporting period, these techniques were generally unsuccessful, as they steered
the Fund into Underlying Funds that collectively underperformed the S&P 500(R)
Index after adjusting for Underlying Fund expenses and strategic allocation
policy.

Underlying Fixed Income Funds were selected based upon the type and country of
issuance of the securities in which they invested, the average credit quality of
those securities and their duration.(3)

It is usually difficult to identify any single factor that had a
disproportionate effect on the Fund's relative performance, but during the
reporting period, one theme had a distinctive impact. We tilted the Fund toward
Underlying Funds that prized earnings stability, because higher-quality stocks
with stable earnings have historically been rewarded with higher returns than
lower-quality stocks with earnings that are less stable. Unfortunately, when the
global equity markets turned positive in the spring of 2009, investors
aggressively bought the riskiest and lowest-quality securities in anticipation
that these securities would benefit most from a recovery. This trend persisted
throughout the reporting period, and stocks with negative earnings and cash
flows were among the best performers. This so-called junk rally served as a
significant drag on the Fund's relative performance during the reporting period.

DID YOU MAKE ANY SIGNIFICANT CHANGES IN THE FUND'S ALLOCATIONS DURING THE
REPORTING PERIOD?

The most significant change we made during the reporting period was a gradual,
protracted shift away from large-cap growth-oriented Underlying Funds toward
Underlying Funds with a more neutral style and capitalization focus.
Specifically, we reduced the Fund's allocations to MainStay Large Cap Growth
Fund, MainStay Growth Equity Fund and MainStay 130/30 Growth Fund and increased
the Fund's allocations to MainStay Epoch U.S. All Cap Fund and, to a lesser
degree, to MainStay 130/30 Core Fund. This

2. See footnote on page 48 for more information on the S&P 500(R) Index.
3. Duration is a measure of the price sensitivity of a fixed-income investment
   to changes in interest rates. Duration is expressed as a number of years and
   is considered a more accurate sensitivity gauge than average maturity.

                                                   mainstayinvestments.com    51



shift had a positive impact on the Fund's performance, as value-oriented
smaller-capitalization stocks outpaced growth-oriented larger-cap stocks as the
reporting period progressed. We have substantially reduced the Fund's exposure
to growth-oriented stocks over the past two and a half years. At the end of the
current reporting period, the Fund was evenly positioned between growth and
value.

During the reporting period, the Fund initiated new positions in MainStay Epoch
Global Choice Fund
and MainStay Convertible Fund. We chose MainStay Epoch Global Choice Fund to
further diversify the Fund across management strategies and to enhance the
Fund's exposure to desirable cash flow metrics. MainStay Convertible Fund was
chosen to increase the Fund's overall responsiveness to movements in the equity
market while incrementally lowering the Fund's average credit quality and
duration.

DURING THE REPORTING PERIOD, WHICH UNDERLYING EQUITY FUND POSITIONS HAD THE
HIGHEST TOTAL RETURNS AND WHICH HAD THE LOWEST TOTAL RETURNS?

MainStay U.S. Small Cap Fund and MainStay Epoch U.S. All Cap Fund generated the
highest total returns among the Underlying Equity Funds in which the Fund
invested, as these Underlying Funds reached furthest down the capitalization
spectrum. The worst returns came from Underlying Funds that invest abroad,
namely MainStay ICAP International Fund and MainStay 130/30 International Fund.
These Underlying Equity Funds were hampered not only by comparatively weak
overseas returns in local currencies but also by a strengthening U.S. dollar.

DURING THE REPORTING PERIOD, WHICH UNDERLYING EQUITY FUNDS MADE THE STRONGEST
CONTRIBUTIONS TO THE FUND'S ABSOLUTE PERFORMANCE AND WHICH UNDERLYING EQUITY
FUNDS DETRACTED THE MOST?

Among the Underlying Equity Funds in which the Fund invested, MainStay MAP Fund
and MainStay Growth Equity Fund were the strongest contributors to the Fund's
absolute performance.

During the reporting period, no Underlying Equity Funds in which the Fund
invested provided negative returns. The weakest contributions to the Fund's
performance came from two of its smallest positions, MainStay S&P 500 Index Fund
and MainStay Epoch Global Choice Fund.

WHAT FACTORS INFLUENCED PERFORMANCE IN THE FIXED-INCOME PORTION OF THE FUND
DURING THE SIX MONTHS ENDED APRIL 30, 2010?

U.S. Treasury yields were largely unchanged over
the course of the reporting period. Signs of economic strength, improving
corporate profitability and a large supply of new issuance threatened to push
rates higher. These factors, however, were offset by concerns about corporate
and sovereign default risk (holding company Dubai World and Greece were notable
examples) and by questions about the sustainability of the economic recovery.
Lower-quality fixed-income securities generally outperformed higher-quality
fixed-income securities as credit spreads(4) narrowed, driving bond prices
higher.

HOW DID THE FUND ALLOCATE ASSETS AMONG THE UNDERLYING FIXED INCOME FUNDS DURING
THE REPORTING PERIOD?

In anticipation that Treasury rates would ultimately rise and that credit
spreads would continue to narrow from the wider-than-normal levels we had
observed, we shortened the Fund's duration and reestablished
a bias toward lower-quality instruments. We implemented these strategies
primarily by increasing the Fund's holdings in MainStay Floating Rate Fund,
MainStay High Yield Opportunities Fund and MainStay High Yield Corporate Bond
Fund.

DURING THE REPORTING PERIOD, WHICH UNDERLYING FIXED INCOME FUNDS HAD THE
STRONGEST ABSOLUTE PERFORMANCE AND WHICH ONES DETRACTED FROM THE FUND'S ABSOLUTE
PERFORMANCE?

The Fund's best-performing Underlying Fixed Income Fund holdings were MainStay
High Yield Opportunities Fund and MainStay High Yield Corporate Bond Fund, both
of which benefited from the contraction in credit spreads that accompanied the
economic recovery. MainStay Indexed Bond Fund and Main-
Stay Intermediate Term Bond Fund were the worst-performing Underlying Fixed
Income Funds, as both invest in higher-quality debt instruments. Still, both of
these Underlying Fixed Income Funds posted positive results during the reporting
period.

   yield between a security or type of security and comparable U.S. Treasury
   issues. The terms may also refer to the difference in yield between two
   specific securities or types of securities at a given time.

60    MainStay Moderate Growth Allocation Fund        The notes to the financial
statements are an integral part of, and should be read in conjunction with, the
financial statements.



NOTES TO FINANCIAL STATEMENTS UNAUDITED

NOTE 1--ORGANIZATION AND BUSINESS:

MainStay Funds Trust (the "Trust") is organized as a Delaware Statutory Trust
and is governed by a Declaration of Trust dated April 8, 2009. The Trust is
registered under the Investment Company Act of 1940, as amended (the "1940 Act")
as an open-end management investment company, and is comprised of twenty-nine
funds (collectively referred to as the "Funds" and each individually, referred
to as a "Fund"). These financial statements and notes relate to the MainStay
Conservative Allocation Fund, MainStay Growth Allocation Fund, MainStay Moderate
Allocation Fund and MainStay Moderate Growth Allocation Fund (collectively
referred to as the "Allocation Funds" and each individually referred to as an
"Allocation Fund"). Each is a diversified fund. Each Allocation Fund is the
successor of a series of Eclipse Funds Inc. with the same name (each a
"Predecessor Fund"). The reorganizations of the Predecessor Funds with and into
the respective Allocation Funds, which were not subject to shareholder approval
under applicable law, occurred on February 26, 2010. All information regarding
and references to periods prior to the commencement of operations of each
Allocation Fund relate to the respective Predecessor Fund.

The Allocation Funds each currently offer five classes of shares. Class A
shares, Class B shares, Class C shares and Class I shares commenced operations
on April 4, 2005. Investor Class shares commenced operations on February 28,
2008. Investor Class and Class A shares are offered at net asset value ("NAV")
per share plus an initial sales charge. No sales charge applies on investments
of $1 million or more (and certain other qualified purchases) in Investor Class
and Class A shares, but a contingent deferred sales charge is imposed on certain
redemptions of such shares within one year of the date of purchase. Class B
shares and Class C shares are offered at NAV without an initial sales charge,
although a declining contingent deferred sales charge may be imposed on
redemptions made within six years of purchase of Class B shares and a 1.00%
contingent deferred sales charge may be imposed on redemptions made within one
year of purchase of Class C shares. Class I shares are offered at NAV and are
not subject to a sales charge. Depending upon eligibility, Class B shares
convert to either Investor Class or Class A shares eight years after the date
they were purchased. Additionally, depending upon eligibility, Investor Class
shares may convert to Class A shares and Class A shares may convert to Investor
Class shares. The five classes of shares have the same voting (except for issues
that relate solely to one class), dividend, liquidation and other rights, and
the same terms and conditions, except that Class B and Class C shares are
subject to higher distribution and/or service fee rates than Investor Class and
Class A shares under a distribution plan pursuant to Rule 12b-1 under the 1940
Act. Class I shares are not subject to a distribution and/or service fee.

The investment objective for each of the Allocation Funds is as follows:

The CONSERVATIVE ALLOCATION FUND seeks current income and, secondarily, long-
term growth of capital.

The GROWTH ALLOCATION FUND seeks long-term growth of capital.

The MODERATE ALLOCATION FUND seeks long-term growth of capital and, secondarily,
current income.

The MODERATE GROWTH ALLOCATION FUND seeks long-term growth of capital and,
secondarily, current income.

The Allocation Funds are funds-of-funds and may invest in other Funds of the
Trust as well as funds of the Eclipse Funds and The MainStay Funds, each a
Massachusetts business trust, and Eclipse Funds Inc., a Maryland Corporation,
for which New York Life Investment Management LLC also serves as manager
("Underlying Funds").

NOTE 2--SIGNIFICANT ACCOUNTING POLICIES:

The Allocation Funds prepare their financial statements in accordance with
accounting principles generally accepted in the United States of America
("GAAP") and follow the significant accounting policies described below.

(A) SECURITIES VALUATION.  Investments in Underlying Funds are valued at their
NAV at the close of business each day. The Allocation Funds' other investments
and securities held by the Underlying Funds are valued as described below.

Debt securities are valued at prices supplied by a pricing agent or broker
selected by the funds' manager in consultation with the funds' subadvisor, if
any, whose prices reflect broker/dealer supplied valuations and electronic data
processing techniques, if such prices are deemed by the funds' manager in
consultation with the funds' subadvisor, if any, to be representative of market
values, at the regular close of trading of the New York Stock Exchange
("Exchange") (generally 4:00 p.m. Eastern time) on each day the Exchange is open
for business ("valuation date").

Equity securities are valued at the latest quoted sales prices as of the close
of regular trading on the Exchange on each valuation date. Securities that are
not traded on the valuation date are valued at the mean of the latest quoted bid
and asked prices. Prices normally are taken from the principal market in which
each security trades.

Temporary cash investments acquired over 60 days prior to maturity are valued
using the latest bid prices or using valuations based on a matrix system (which
considers such factors as security prices, yields, maturities, and ratings),
both as furnished by independent pricing services. Other temporary cash
investments which mature in 60 days or less ("short-term investments") are
valued at amortized cost. The amortized cost method involves valuing a security
at its cost on the date of purchase and thereafter assuming a

NOTES TO FINANCIAL STATEMENTS UNAUDITED (CONTINUED)



constant amortization to maturity of the difference between the principal amount
due at maturity and cost.

Securities for which market quotations are not readily available are valued by
methods deemed in good faith by the Funds' Board to represent fair value. Equity
and non-equity securities which may be valued in this manner include, but are
not limited to: (i) a security the trading for which has been halted or
suspended; (ii) a debt security that has recently gone into default and for
which there is not a current market quotation; (iii) a security of an issuer
that has entered into a restructuring; (iv) a security that has been de-listed
from a national exchange; (v) a security the market price of which is not
available from an independent pricing source or, if so provided, does not, in
the opinion of the fund's manager, reflect the security's market value; and (vi)
a security where the trading on that security's principal market is temporarily
closed at a time when, under normal conditions, it would be open. At April 30,
2010, the Allocation Funds did not hold securities that were valued in such a
manner.

"Fair value" is defined as the price that the Allocation Fund would receive upon
selling an investment in an orderly transaction to an independent buyer in the
principal or most advantageous market of the investment. Fair value measurements
are determined within a framework that has established a three-tier hierarchy
which maximizes the use of observable market data and minimizes the use of
unobservable inputs to establish classification of fair value measurements for
disclosure purposes. "Inputs" refer broadly to the assumptions that market
participants would use in pricing the asset or liability, including assumptions
about risk, such as the risk inherent in a particular valuation technique used
to measure fair value using a pricing model and/or the risk inherent in the
inputs for the valuation technique. Inputs may be observable or unobservable.
Observable inputs are inputs that reflect the assumptions market participants
would use in pricing the asset or liability based on market data obtained from
sources independent of the reporting entity. Unobservable inputs are inputs that
reflect the reporting entity's own assumptions about the assumptions market
participants would use in pricing the asset or liability developed based on the
information available in the circumstances. The inputs or methodology used for
valuing securities may not be an indication of the risks associated with
investing in those securities. The three-tier hierarchy of inputs is summarized
in the three broad Levels listed below.

- - Level 1--quoted prices in active markets for identical investments

- - Level 2--other significant observable inputs (including quoted prices for
  similar investments in active markets, interest rates and yield curves,
  prepayment speeds, credit risks, etc.)

- - Level 3--significant unobservable inputs (including the Allocation Fund's own
  assumptions about the assumptions that market participants would use in
  determining the fair value of investments)

The aggregate value by input level, as of April 30, 2010, for each Allocation
Fund's investments is included at the end of each Allocation Fund's Portfolio of
Investments.

The valuation techniques used by the Allocation Funds to measure fair value
during the six-month period ended April 30, 2010 maximized the use of observable
inputs and minimized the use of unobservable inputs. The Underlying Funds may
have utilized some of the following fair value techniques: multi-dimensional
relational pricing models, option adjusted spread pricing and estimating the
price that would have prevailed in a liquid market for an international equity
security given information available at the time of evaluation, when there are
significant events after the close of local foreign markets. For the six-month
period ended April 30, 2010, there have been no changes to the fair value
methodologies.

(B) FEDERAL INCOME TAXES.  Each of the Allocation Funds is treated as a separate
entity for federal income tax purposes. The Allocation Funds' policy is to
comply with the requirements of the Internal Revenue Code of 1986, as amended
(the "Internal Revenue Code") applicable to regulated investment companies and
to distribute all of the taxable income to the shareholders of each Allocation
Fund within the allowable time limits. Therefore, no federal income tax
provision is required.

Management evaluates its tax positions to determine if the tax positions taken
meet the minimum recognition threshold in connection with accounting for
uncertainties in income tax positions taken or expected to be taken for the
purposes of measuring and recognizing tax liabilities in the financial
statements. Recognition of tax benefits of an uncertain tax position is required
only when the position is "more likely than not" to be sustained assuming
examination by taxing authorities. Management has analyzed the Allocation Funds'
tax positions taken on federal income tax returns for all open tax years
(current and prior three tax years), and has concluded that no provision for
federal income tax is required in the Allocation Funds' financial statements.
The Allocation Funds' federal and state income and federal excise tax returns
for tax years for which the applicable statutes of limitations have not expired
are subject to examination by the Internal Revenue Service and state departments
of revenue.

(C) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS.  Dividends and distributions
are recorded on the ex-dividend date. The Conservative Allocation Fund intends
to declare and pay dividends of net investment income, if any, quarterly and
distributions of net realized capital gains, if any, annually. The other
Allocation Funds intend to declare and pay dividends of net investment income
and

62    Mainstay Allocation Funds



distributions of net realized capital gains, if any, annually. Unless the
shareholder elects otherwise, all dividends and distributions are reinvested in
the same class of shares of the respective Allocation Fund, at NAV. Dividends
and distributions to shareholders are determined in accordance with federal
income tax regulations and may differ from GAAP.

(D) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  The Allocation Funds record
security transactions on the trade date. Realized gains and losses on security
transactions are determined using the identified cost method. Dividends and
distributions received by the Allocation Funds from the Underlying Funds are
recorded on the ex-dividend date.

Investment income and realized and unrealized gains and losses on investments of
the Allocation Funds are allocated to separate classes of shares pro rata based
upon their relative net assets on the date the income is earned or realized and
unrealized gains and losses are incurred.

(E) EXPENSES.  Expenses of the Trust are allocated to the individual Allocation
Funds in proportion to the net assets of the respective Allocation Funds when
the expenses are incurred, except where direct allocations of expenses can be
made. Expenses (other than transfer agent expenses and fees incurred under the
shareholder services plans and the distribution plans further discussed in Note
3(B)) are allocated to separate classes of shares pro rata based upon their
relative NAV on the date the expenses are incurred. The expenses borne by each
Allocation Fund, including those of related parties to the Allocation Funds, are
shown in the Statement of Operations.

In addition, the Allocation Funds bear a pro rata share of the fees and expenses
of the Underlying Funds in which they invest. Because the Underlying Funds have
varied expense and fee levels and the Allocation Funds may own different
proportions of the Underlying Funds at different times, the amount of fees and
expenses incurred indirectly by the Allocation Funds may vary.

(F) USE OF ESTIMATES.  In preparing financial statements in conformity with
GAAP, management makes estimates and assumptions that affect the reported
amounts and disclosures in the financial statements. Actual results could differ
from those estimates.

(G) INDEMNIFICATIONS.  Under the Trust's organizational documents, its officers
and trustees are indemnified against certain liabilities that may arise out of
performance of their duties to the Trust. Additionally, in the normal course of
business, the Allocation Funds enter into contracts with third-party service
providers that contain a variety of representations and warranties and which
provide general indemnifications. The Allocation Funds' maximum exposure under
these arrangements is unknown, as this would involve future claims that may be
made against the Allocation Funds that have not yet occurred. Based on
experience, management is of the view that the risk of loss in connection with
these potential indemnification obligations is remote. However, there can be no
assurance that material liabilities related to such obligations will not arise
in the future, which could adversely impact the Allocation Funds.

NOTE 3--FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER AND SUBADVISOR.  New York Life Investment Management LLC ("New York
Life Investments" or "Manager"), a registered investment adviser and an
indirect, wholly-owned subsidiary of New York Life Insurance Company ("New York
Life"), serves as the Allocation Funds' Manager, pursuant to a Management
Agreement, as amended ("Management Agreement"). The Manager provides offices,
conducts clerical, recordkeeping and bookkeeping services, and keeps most of the
financial and accounting records required to be maintained by the Allocation
Funds. Except for the portion of salaries and expenses that are the
responsibility of the Allocation Funds, the Manager also pays the salaries and
expenses of all personnel affiliated with the Allocation Funds and the
operational expenses of the Allocation Funds. Madison Square Investors LLC
("Madison Square Investors" or "Subadvisor"), a registered investment adviser
and an indirect, wholly-owned subsidiary of New York Life, serves as Subadvisor
to the Allocation Funds and is responsible for the day-to-day portfolio
management of the Allocation Funds. Pursuant to the terms of a Subadvisory
Agreement between New York Life Investments and the Subadvisor, New York Life
Investments pays for the services of the Subadvisor.

The Allocation Funds do not pay any fees to the Manager in return for the
services performed. The Allocation Funds do, however, indirectly pay a
proportionate share of the management fees paid to the Manager by the Underlying
Funds in which the Allocation Funds invest.

Effective February 26, 2010, New York Life Investments entered into a written
expense limitation agreement under which it has agreed to waive a portion of the
Allocation Funds' management fee or reimburse the expenses of the appropriate
class of the Allocation Funds so that the total ordinary operating expenses
(total ordinary operating expenses excludes taxes, interest, litigation,
extraordinary expenses, brokerage and other transaction expenses relating to the
purchase or sale of portfolio investments, and the fees and expenses of the
Underlying Funds in which an Allocation Fund invests) of a class do not exceed

annually by the Board in connection with its review of the Funds' investment
advisory agreements.  Based on its review, the Board may agree to maintain,
modify or terminate the agreements.

(F) SMALL ACCOUNT FEE.  Shareholders with small accounts adversely impact the
cost of providing transfer agency services. In an effort to reduce total
transfer agency expenses, the Allocation Funds have implemented a small account
fee on certain types of accounts. Certain shareholders with an account balance
of less than $1,000 are charged an annual per account fee of $20 (assessed semi-
annually). These fees are included in transfer agent fees shown on the Statement
of Operations.

(G) OTHER.  Pursuant to the Management Agreement, a portion of the cost of legal
services provided to the Allocation Funds by the Office of the General Counsel
of New York Life Investments is payable directly by the Allocation Funds. For
the six-month period ended April 30, 2010, these fees, which are included in
professional fees shown on the Statement of Operations, were as follows:

NOTE 5--CUSTODIAN:

State Street is the custodian of the cash and the securities of the Allocation
Funds. Custodial fees are charged to the Allocation Funds based on the market
value of securities in the Allocation Funds and the number of certain cash
transactions incurred by the Allocation Funds.

NOTE 6--LINE OF CREDIT:

The Allocation Funds and certain affiliated funds maintain a line of credit with
a syndicate of banks in order to secure a source of funds for temporary purposes
to meet unanticipated or excessive shareholder redemption requests. The line of
credit is in the amount of $125,000,000 and the commitment fee rate is an annual
rate of 0.10% of the average commitment amount, plus a 0.04% up-front payment
payable, regardless of usage, to The Bank of New York Mellon, which serves as
agent to the syndicate. The commitment fee and upfront payment are allocated
among certain MainStay Allocation Funds based upon net assets and other factors.
Interest on any revolving credit loan is charged based upon the Federal Funds
Advances rate or the one month LIBOR rate, whichever is higher. There were no
borrowings made or outstanding with respect to the Allocation Funds on the line
of credit during the six-month period ended April 30, 2010.

(a) In addition to any automatic conversion features
    described above in Note 1 with respect to Investor
    Class, Class A and B shares, you generally may also
    elect to convert your shares on a voluntary basis
    into another share class of the same fund for which
    you are eligible. However, the following
    limitations apply:
</Table>


     - Investor Class and Class A shares that remain subject to a CDSC are
       ineligible for a voluntary conversion; and

     - All Class B and C shares are ineligible for a voluntary conversion.

These limitations do not impact any automatic conversion features described in
Note 1 with respect to Investor Class, Class A and B shares.

An investor or an investor's financial intermediary may contact the Fund to
request a voluntary conversion between shares classes of the same Fund. You may
be required to provide sufficient information to establish eligibility to
convert to the new share class. All permissible conversions will be made on the
basis of the relevant NAVs of the two classes without the imposition of any
sales load, fee or other charge. If you fail to remain eligible for the new
share class, you may automatically be converted back to your original share
class, or into another share class, if appropriate.


NOTE 9--NEW ACCOUNTING PRONOUNCEMENT:

In January 2010, the Financial Accounting Standards Board ("FASB") issued
Accounting Standards Update ("ASU") No. 2010-06 "Improving Disclosures about
Fair Value Measurements". ASU 2010-06 requires reporting entities to make new
disclosures about amount and reasons for significant transfers in and out of
Level 1 and Level 2 fair value measurements and input and valuation techniques
used to measure fair value for both recurring and nonrecurring fair value
measurements that fall in either Level 2 or Level 3, and information on
purchased, sales, issuances, and settlements in the roll forward of activity in
Level 3 fair value measures. The new and revised disclosure requirements are
effective for interim and annual reporting periods beginning after December 15,
2009 except for the disclosures about purchased, sales, issuances, and
settlements in the roll forward of activity in Level 3 fair value measures,
which are effective for fiscal years beginning after December 15, 2010. As of
April 30, 2010, the Allocation Funds have adopted ASU 2010-06. The adoption of
ASU 2010-06 has not impacted the amounts reported in the Allocation Funds'
financial statements; however, there are additional disclosures in each of the
Allocation Funds' Portfolio of Investments.

NOTE 10--SUBSEQUENT EVENTS:

In connection with the preparation of the financial statements of the Allocation
Funds as of and for the fiscal six-month period ended April 30, 2010, events and
transactions subsequent to April 30, 2010 through the date the financial
statements were issued have been evaluated by the Allocation Funds' management
for possible adjustment and/or disclosure. No subsequent events requiring
financial statement adjustment or disclosure have been identified.

        MESSAGE FROM THE PRESIDENT AND SEMIANNUAL REPORT


        Unaudited - April 30, 2010



MESSAGE FROM THE PRESIDENT

During the six months ended April 30, 2010, stock and bond markets generally
advanced, despite some volatility in January and February. Domestic small-cap
stocks were particularly strong, and U.S. stocks at all capitalization levels
provided double digit returns. Value stocks outpaced growth stocks for companies
of all sizes during this period.

International stocks provided positive returns overall, but results varied
widely by country. Concerns about Greece's ability to meet its debt obligations
led many investors to abandon their holdings in Greece and question their
investments in several peripheral European nations where perceived risk had
increased. For the six months ended April 30, 2010, equities in the Far East
(including Japan) tended to be stronger than those in Europe.

The economic recovery in the United States continued. Real gross domestic
product advanced in the first quarter of 2010, though at a slower pace than in
the fourth quarter of 2009. The Federal Open Market Committee kept the targeted
federal funds rate at a historically low level throughout the six-month period,
which prompted many investors to leave the safety of U.S. Treasury securities in
search of higher yield.

In the high-yield bond market, lower-rated credits tended to be the strongest
performers. With investment-grade investors crossing into high-yield territory,
however, the highest-rated high-yield credits also saw strong demand. In the
municipal market, new-issue supply was reduced by government incentives that
encouraged municipal issuers to raise funds in the taxable market. In the
leveraged-loan market, new issuance strengthened, but extensive repayments
caused the market as a whole to contract.


During the period covered by this report, MainStay's portfolio managers sought
to make the most of market conditions within the investment strategies and risk
parameters of their respective Funds. While individual markets and Fund results
may vary, our pursuit of competitive returns over full market cycles has never
changed.

The information that follows provides a closer look
at the securities, strategies and market conditions that affected your MainStay
Fund(s) during the period covered by this report. Of course, past performance is
no guarantee of future results. Even in a rising market, we believe that
maintaining a long-term perspective can be valuable. At MainStay, we believe
that in all markets, broad diversification, gradual allocation adjustments and
regular portfolio reviews can help guide you toward your long-range financial
goals.

We thank you for choosing MainStay Funds, and we look forward to serving your
investment needs for many years to come.

Sincerely,

/s/ STEPHEN P. FISHER

Stephen P. Fisher
President

1. Performance tables and graphs do not reflect the deduction of the taxes that
   a shareholder would pay on distribution or Fund-share redemptions. Total
   returns reflect maximum applicable sales charges explained in this paragraph,
   change in share price, and reinvestment of dividend and capital gain
   distributions. The graphs assume an initial investment of $25,000 for Class A
   shares and $10,000 for all other classes and reflect the deduction of all
   sales charges that would have applied for the period of investment. Class A
   shares generally have a $25,000 minimum initial investment with no minimum
   subsequent purchase amount. For investors that, in the aggregate, have assets
   of $100,000 or more invested in any share classes of any of the MainStay
   Funds, the minimum initial investment is $15,000. Investor Class and Class A
   shares are sold with a maximum initial sales charge of 5.5% and an annual
   12b-1 fee of 0.25%. Class C shares are sold with no initial sales charge and
   are subject to a contingent deferred sales charge ("CDSC") of 1.00%. Class I
   shares are sold with no initial sales charge or CDSC, have no annual 12b-1
   fee, and are generally available to corporate and institutional investors or
   individual investors with a minimum initial investment of $5 million.
   Performance figures reflect certain fee waivers and/or expense limitations,
   without which total returns would have been lower. For information on current
   fee waivers and/or expense limitations, please refer to the notes to the
   financial statements. The Fund is the successor to the Epoch U.S. All Cap
   Equity Fund. Effective January 4, 2010, the Fund changed its fiscal year end
   from December 31 to October 31.
2. Performance figures for Investor Class and Class C shares, first offered
   November 16, 2009, include the historical performance of Class I shares
   through November 15, 2009 adjusted for differences in certain contractual
   expenses and fees.

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY EPOCH GLOBAL CHOICE FUND
(UNAUDITED)
- --------------------------------------------------------------------------------

The example below is intended to describe the fees and expenses borne by
shareholders during the six-month period from November 1, 2009, to April 30,
2010, and the impact of those costs on your investment.

EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, exchange fees, and sales charges (loads) on
purchases (as applicable), and (2) ongoing costs, including management fees,
distribution and/or service (12b-1) fees, and other Fund expenses (as
applicable). This example is intended to help you understand your ongoing costs
(in dollars) of investing in the Fund and to compare these costs with the
ongoing costs of investing in other mutual funds. The example is based on an
investment of $1,000 made at the beginning of the six-month period and held for
the entire period from November 1, 2009, to April 30, 2010.

This example illustrates your Fund's ongoing costs in two ways:

- - ACTUAL EXPENSES
The second and third data columns in the table below provide information about
actual account values and actual expenses. You may use the information in these
columns, together with the amount you invested, to estimate the expenses that
you paid during the six-months ended April 30, 2010. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number under the heading entitled "Expenses Paid
During Period" to estimate the expenses you paid on your account during this
period.

- - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The fourth and fifth data columns in the table below provide information about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense ratio and an assumed rate of return of 5% per year before expenses,
which is not the Fund's actual return. The hypothetical account values and
expenses may not be used to estimate the actual ending account balances or
expenses you paid for the six-month period shown. You may use this information
to compare the ongoing costs of investing in the Fund with the ongoing costs of
investing in other Funds. To do so, compare this 5% hypothetical example with
the 5% hypothetical examples that appear in the shareholder reports of the other
Funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as
redemption fees, if applicable, exchange fees, or sales charges (loads).
Therefore, the fourth and fifth data columns of the table are useful in
comparing ongoing costs only and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.

1. Expenses are equal to the Fund's annualized expense ratio of each class
   (1.57% for Investor Class, 1.55% for Class A, 2.34% for Class C and 1.30% for
   Class I) multiplied by the average account value over the period, divided by
   365 and multiplied by 181 days for Class A and Class I (to reflect the one-
   half year period) and 168 days for Investor Class and Class C (to reflect the
   since-inception period).The table above represents actual expenses incurred
   during the one-half year period.
2. Expenses paid during the period reflect ongoing costs for the period from
   inception through April 30, 2010. Had these shares been offered for the full
   six-month period ended April 30, 2010, and had the Fund provided a
   hypothetical 5% annualized return, expenses paid during the period would have
   been $7.85 for Investor Class and $11.68 for Class C and the ending account
   value would have been $1,017.00 for Investor Class and $1,013.20 for Class C.
3. Investor Class and Class C shares began investment operations on November 16,
   2009.

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS(1)


QUESTIONS ANSWERED BY PORTFOLIO MANAGERS WILLIAM PRIEST, CFA, AND MICHAEL
WELHOELTER, CFA, OF EPOCH INVESTMENT PARTNERS, INC. (EPOCH), THE FUND'S
SUBADVISOR.

HOW DID MAINSTAY EPOCH GLOBAL CHOICE FUND PERFORM RELATIVE TO ITS PEERS AND ITS
BENCHMARK FOR THE FOUR MONTHS ENDED APRIL 30, 2010?

Excluding all sales charges, MainStay Epoch Global Choice Fund returned 2.30%
for Investor Class shares, 2.30% for Class A shares and 2.08% for Class C shares
for the four months ended April 30, 2010. Over the same period, the Fund's Class
I shares returned 2.47%. All share classes underperformed the 3.72% return of
the average Lipper(2) global multi-cap core fund, the 8.23% return of the
Russell 3000(R) Index() and the 3.25% return of the MSCI World Index() for the
four months ended April 30, 2010. The MSCI World Index is the Fund's broad-based
securities-market index. See page 5 for Fund returns with sales charges.

WHAT MAJOR FACTORS INFLUENCED THE FUND'S RELATIVE PERFORMANCE DURING THE FOUR-
MONTH REPORTING PERIOD?

The period saw a continuation of the market's focus on lower-quality stocks that
began in March 2009, as short rates collapsed by nearly five percentage points
from midyear 2007, coupled with growing confidence that the worst recession
since World War II was behind us. Companies with less-visible cash flows, high
financial leverage and smaller capitalizations performed well, as did materials
and other cyclical sectors. Our view remained that these factors had run their
course as market drivers. We believed that a more important consideration would
be Europe's ability to solve a financial crisis emanating from the Greek debt
situation and the United States' ability to transition to a sustainable recovery
led by the private sector. Market levels had priced in only positive assumptions
in both cases.

Global equity markets recorded positive returns during the reporting period, and
the Fund rose as well. The main positive factor in the Fund's performance
relative to the MSCI World Index was stock selection in the financials, consumer
discretionary and health care sectors. In addition, the Fund benefited by having
little exposure to underperforming sectors such as utilities. Somewhat
offsetting these positive factors was the underperformance of holdings in
information technology and industrials compared to the average returns of the
respective sectors in the Index. The health care sector lagged the Index return
as the uncertainty surrounding health care reform played out.

DURING THE REPORTING PERIOD, WHICH SECTORS MADE THE STRONGEST CONTRIBUTIONS TO
THE FUND'S ABSOLUTE PERFORMANCE AND WHICH SECTORS MADE THE WEAKEST
CONTRIBUTIONS?

On an absolute basis, the strongest-contributing sectors to the Fund's
performance were consumer discretionary, financials and industrials. On the
whole, the Fund's consumer discretionary holdings performed well as investors
continued to expect improvements in employment and wage growth. Financials
marginally outperformed the MSCI World Index, as concerns mounted over the
potential impact of global regulatory reform in the wake of the Security and
Exchange Commission's case against Goldman Sachs. Financial companies with the
least credit exposure performed best. The Fund's holdings in the industrials
sector also performed well, especially those with exposure to the aerospace
industry.

During the reporting period, the sectors that detracted the most from the Fund's
absolute performance were materials, telecommunication services and information
technology. Materials stocks in general paused after a strong run in 2009, as
investors began to discount the effects of an economic slowdown in China. Metals
stocks were particularly hard hit. Telecommunication services lagged other
sectors as investors found defensive companies less appealing than those with
greater economic sensitivity. Information technology stocks generally performed
well, but our holdings lagged smaller-capitalization information technology
stocks. Companies with more exposure to hardware and companies that manufacture
commodity-type products were the strongest performers.

WHICH INDIVIDUAL STOCKS WERE THE STRONGEST CONTRIBUTORS TO THE FUND'S ABSOLUTE
PERFORMANCE DURING THE REPORTING PERIOD AND WHICH STOCKS DETRACTED?

On an absolute basis, insurance company Prudential Financial, cable company
Comcast and Korea-based automotive company Hyundai Motor made the strongest
contributions to the Fund's performance. Prudential Financial advanced during
the four months ended April 30, 2010, as investors sought high quality financial
stocks that had previously lagged other more speculative banks. Comcast
benefited from valuation improvements, expected decreases in capital
expenditures and anticipated synergies with NBC Universal. Hyundai Motor saw its
share price rise on increasing

sales in China and investors' hopes that the company could capitalize on turmoil
in the U.S. auto market.

Health care and science company Bayer A.G., agricultural products company
Monsanto and diversified health care benefits company Aetna were among the
greatest detractors from the Fund's absolute performance during the four-month
reporting period. Shares of Bayer A.G. declined on disappointing guidance for
the company's health care and crop science units. Monsanto suffered from lower-
than-expected demand from farmers, especially in northern markets. Shares of
Aetna fell because of poor product pricing and investor concerns about health
care reform legislation.

DID THE FUND MAKE ANY SIGNIFICANT PURCHASES OR SALES DURING THE REPORTING
PERIOD?

Among the stocks that the Fund purchased during the reporting period were
Internet software & services company Yahoo!, aerospace & defense company
Bombardier and Comcast. We established a Fund position in Yahoo! to take
advantage of the company's partnership with Microsoft. We believed that the
partnership would help Yahoo! reduce expenses, increase market share and
possibly benefit from increased online advertising. Our investment in Bombardier
reflected our view that the transportation segment is a stable and growing
profit and cash-flow contributor that is underappreciated by investors. We
believed that Bombardier's rail segment could benefit from rail stimulus
spending in the United States, and we were attracted by the company's strong
position in emerging markets, including China. We liked Comcast not only for its
leading position within its industry but also because it increased its return of
capital to shareholders through an expanded share buyback. In our view,
Comcast's acquisition of NBC should offer strategic benefits and increase the
shares' valuation.

During the reporting period, we exited the Fund's position in Monsanto as we
became concerned over pricing issues for the company's products. We eliminated
the Fund's holdings in Aetna, believing expectations had not fully discounted
the potential negatives of health care reform legislation. We sold the Fund's
position in computers & peripherals company Apple ahead of the release of the
iPad on the belief that the stock had achieved fair value.

HOW DID THE FUND'S WEIGHTINGS CHANGE DURING THE REPORTING PERIOD?

During the reporting period, we increased the Fund's weightings in the
industrials, consumer discretionary and financials sectors. Within industrials,
we added Fund positions in aerospace & defense companies Boeing and Bombardier
and cable manufacturer Prysmian. In consumer discretionary, we added Fund
positions in Comcast, auto manufacturer Daimler Benz and specialty retailer TJX.
In financials, we added Fund positions in capital markets company Ameriprise,
bank holding company CIT Group and brokerage services provider TD Ameritrade.

We reduced the Fund's exposure to the health care, consumer staples and
information technology sectors. In health care, we sold positions in Aetna,
dialysis service provider DaVita and pharmaceutical and diagnostics company
Roche Holding. In consumer staples, we sold positions in international tobacco
company Imperial Tobacco and discount retailing giant Wal-Mart Stores. In
information technology, we sold the Fund's positions in Apple and Taiwan
Semiconductor Manufacturing Company.

HOW WAS THE FUND POSITIONED AT THE END OF APRIL 2010, AND HOW DID THIS
POSITIONING AFFECT THE FUND'S PERFORMANCE?

As of April 30, 2010, the Fund's most substantially overweight sectors relative
to the MSCI World Index were information technology and health care. The
overweight postion in information technology detracted, largely because of the
Fund's sizable position in Microsoft, which underperformed the sector. Because
of effective stock selection, the Fund's overweight position in health care
contributed positively to the Fund's relative performance during the reporting.

On the same date, the Fund's most substantially underweight sectors relative to
the MSCI World Index were financials and energy. Effective stock selection in
both of these sectors helped the Fund's relative performance during the
reporting period.

NOTES TO FINANCIAL STATEMENTS UNAUDITED

NOTE 1--ORGANIZATION AND BUSINESS:

MainStay Funds Trust (the "Trust") is organized as a Delaware Statutory Trust
and is governed by a Declaration of Trust dated April 8, 2009. The Trust is
registered under the Investment Company Act of 1940, as amended (the "1940
Act"), as an open-end management investment company, and is comprised of twenty-
nine funds (collectively referred to as the "Funds"). These financial statements
and notes relate only to the MainStay Epoch Global Choice Fund (the "Fund"), a
diversified fund. The Fund is the successor to the Epoch U.S. All Cap Equity
Fund (the "Predecessor Fund"), which was a series of a different registered
investment company for which Epoch Investment Partners, Inc. served as
investment adviser.

The Fund currently offers 4 classes of shares. Investor Class and Class C shares
were seeded as of the close of business on November 13, 2009 and were first
offered and commenced operations on November 16, 2009. Class I shares and Class
A shares commenced operations (under former designations) on July 25, 2005 and
August 15, 2006, respectively. Effective, January 4, 2010, the Fund changed its
fiscal year end and tax year end from December 31 to October 31. Investor Class
and Class A shares are offered at net asset value ("NAV") per share plus an
initial sales charge. No sales charge applies on investments of $1 million or
more (and certain other qualified purchases) in Investor Class and Class A
shares, but a contingent deferred sales charge is imposed on certain redemptions
of such shares within one year of the date of purchase. Class C shares are
offered at NAV without an initial sales charge, although a 1.00% contingent
deferred sales charge may be imposed on redemptions made within one year of
purchase of Class C shares. Class I shares are offered at NAV and are not
subject to a sales charge. Depending upon eligibility, Investor Class shares may
convert to Class A shares and Class A shares may convert to Investor Class
shares. The four classes of shares have the same voting (except for issues that
relate solely to one class), dividend, liquidation and other rights, and the
same terms and conditions, except that Class C shares are subject to higher
distribution and/or service fee rates than Investor Class and Class A shares
under a distribution plan pursuant to Rule 12b-1 under the 1940 Act. Class I
shares are not subject to a distribution and/or service fee.

The Fund's investment objective is to seek long term capital appreciation.

The financial statements of the Fund reflect the historical results of the
Institutional Class and P shares of the Predecessor Fund prior to its
reorganization. (See Note 10.) Upon the completion of the reorganization, the
Class I and Class A shares of the Fund assumed the performance, financial and
other information of the Institutional Class and Class P shares, respectively.
All information regarding and references to periods prior to the commencement of
operations of the Fund refer to the Predecessor Fund.

NOTE 2--SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with accounting
principles generally accepted in the United States of America ("GAAP") and
follows the significant accounting policies described below.

(A) SECURITIES VALUATION.  Equity securities are valued at the latest quoted
sales prices as of the close of regular trading on the New York Stock Exchange
("Exchange") (generally 4:00 p.m. Eastern time) on each day the Fund is open for
business ("valuation date"). Securities that are not traded on the valuation
date are valued at the mean of the latest quoted bid and asked prices. Prices
normally are taken from the principal market in which each security trades.
Investments in other mutual funds are valued at their NAVs as of the close of
the New York Stock Exchange on the valuation date.

Temporary cash investments acquired over 60 days prior to maturity are valued
using the latest bid prices or using valuations based on a matrix system (which
considers such factors as security prices, yields, maturities, and ratings),
both as furnished by independent pricing services. Other temporary cash
investments which mature in 60 days or less ("short-term investments") are
valued at amortized cost. The amortized cost method involves valuing a security
at its cost on the date of purchase and thereafter assuming a constant
amortization to maturity of the difference between the principal amount due at
maturity and cost.

Certain events may occur between the time that foreign markets close, on which
securities held by the Fund principally trade, and the time at which the Fund's
NAV is calculated. These events may include, but are not limited to, situations
relating to a single issuer in a market sector, significant fluctuations in U.S.
or foreign markets, natural disasters, armed conflicts, governmental actions or
other developments not tied directly to the securities markets. Should the
Manager or Subadvisor, as defined in Note 3(A), conclude that such events may
have affected the accuracy of the last price reported on the local foreign
market, the Manager or Subadvisor may, pursuant to procedures adopted by the
Fund's Board, adjust the value of the local price to reflect the impact on the
price of such securities as a result of such events. Additionally, international
equity securities are also fair valued whenever the movement of a particular
index exceeds certain thresholds. In such cases, the securities are fair valued
by applying factors provided by a third party vendor in accordance with the
Fund's policies and procedures. At April 30, 2010, certain foreign equity
securities held by the Fund were fair valued.

Securities for which market quotations are not readily available are valued by
methods deemed in good faith by the Fund's Board to represent fair value. Equity
and non-equity securities which may be valued in this manner include, but are
not limited to: (i) a security the trading for which has been halted or
suspended; (ii) a debt security that has recently gone into default and for
which there is

20    MainStay Epoch Global Choice Fund



not a current market quotation; (iii) a security of an issuer that has entered
into a restructuring; (iv) a security that has been de-listed from a national
exchange; (v) a security the market price of which is not available from an
independent pricing source or, if so provided, does not, in the opinion of the
Fund's Manager or Subadvisor, as defined in Note 3(A), reflect the security's
market value; and (vi) a security where the trading on that security's principal
market is temporarily closed at a time when, under normal conditions, it would
be open. At April 30, 2010, the Fund did not hold securities that were valued in
such a manner.

"Fair value" is defined as the price that the Fund would receive upon selling an
investment in an orderly transaction to an independent buyer in the principal or
most advantageous market of the investment. Fair value measurements are
determined within a framework that has established a three-tier hierarchy which
maximizes the use of observable market data and minimizes the use of
unobservable inputs to establish classification of fair value measurements for
disclosure purposes. "Inputs" refer broadly to the assumptions that market
participants would use in pricing the asset or liability, including assumptions
about risk, such as the risk inherent in a particular valuation technique used
to measure fair value using a pricing model and/or the risk inherent in the
inputs for the valuation technique. Inputs may be observable or unobservable.
Observable inputs are inputs that reflect the assumptions market participants
would use in pricing the asset or liability based on market data obtained from
sources independent of the reporting entity. Unobservable inputs are inputs that
reflect the reporting entity's own assumptions about the assumptions market
participants would use in pricing the asset or liability developed based on the
information available in the circumstances. The inputs or methodology used for
valuing securities may not be an indication of the risks associated with
investing in those securities. The three-tier hierarchy of inputs is summarized
in the three broad Levels listed below.

- - Level 1--quoted prices in active markets for identical investments

- - Level 2--other significant observable inputs (including quoted prices for
similar investments in active markets, interest rates and yield curves,
prepayment speeds, credit risks, etc.)

- - Level 3--significant unobservable inputs (including the Fund's own assumptions
about the assumptions that market participants would use in determining the fair
value of investments)

The aggregate value by input level, as of April 30, 2010, for the Fund's
investments is included at the end of the Fund's Portfolio of Investments.

The valuation techniques used by the Fund to measure fair value during the four-
month period ended April 30, 2010 maximized the use of observable inputs and
minimized the use of unobservable inputs. The Fund may have utilized some of the
following fair value techniques: multi-dimensional relational pricing models,
option adjusted spread pricing and estimating the price that would have
prevailed in a liquid market for an international equity security given
information available at the time of evaluation, when there are significant
events after the close of local foreign markets. For the four-month period ended
April 30, 2010, there have been no changes to the fair value methodologies.

(B) FEDERAL INCOME TAXES.  The Fund's policy is to comply with the requirements
of the Internal Revenue Code of 1986, as amended (the "Internal Revenue Code")
applicable to regulated investment companies and to distribute all of the
taxable income to the shareholders of the Fund within the allowable time limits.
Therefore, no federal income tax provision is required.

Investment income received by the Fund from foreign sources may be subject to
foreign income taxes. These foreign income taxes are generally withheld at the
source.

Management evaluates its tax positions to determine if the tax positions taken
meet the minimum recognition threshold in connection with accounting for
uncertainties in income tax positions taken or expected to be taken for the
purposes of measuring and recognizing tax liabilities in the financial
statements. Recognition of tax benefits of an uncertain tax position is required
only when the position is "more likely than not" to be sustained assuming
examination by taxing authorities. Management has analyzed the Fund's tax
positions taken on federal income tax returns for all open tax years (current
and prior three tax years), and has concluded that no provision for federal
income tax is required in the Fund's financial statements. The Fund's federal
and state income and federal excise tax returns for tax years for which the
applicable statutes of limitations have not expired are subject to examination
by the Internal Revenue Service and state departments of revenue.

(C) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS.  Dividends and distributions
are recorded on the ex-dividend date. The Fund intends to declare and pay
dividends of net investment income and distributions of net realized capital and
currency gains, if any, annually. Unless the shareholder elects otherwise, all
dividends and distributions are reinvested in the same class of shares of the
Fund, at NAV. Dividends and distributions to shareholders are determined in
accordance with federal income tax regulations and may differ from GAAP.

(D) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  The Fund records security
transactions on the trade date. Realized gains and losses on security
transactions are determined using the identified cost method. Dividend income is
recognized on the ex-dividend date and interest income is accrued as earned
using the effective interest rate method. Discounts and premiums on securities
purchased, other than short-term investments, for the Fund

NOTES TO FINANCIAL STATEMENTS UNAUDITED (CONTINUED)



are accreted and amortized, respectively, on the effective interest rate method
over the life of the respective securities or, in the case of a callable
security, over the period to the first date of call. Discounts and premiums on
short-term investments are accreted and amortized, respectively, on the
straight-line method.

Investment income and realized and unrealized gains and losses on investments of
the Fund are allocated to separate classes of shares pro rata based upon their
relative net assets on the date the income is earned or realized and unrealized
gains and losses are incurred.

(E) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred, except where direct allocations of expenses can be made. Expenses
(other than transfer agent expenses and fees incurred under the shareholder
services plans and the distribution plans further discussed in Note 3(B)) are
allocated to separate classes of shares pro rata based upon their relative NAV
on the date the expenses are incurred. The expenses borne by the Fund, including
those of related parties to the Fund, are shown in the Statement of Operations.

(F) USE OF ESTIMATES.  In preparing financial statements in conformity with
GAAP, management makes estimates and assumptions that affect the reported
amounts and disclosures in the financial statements. Actual results could differ
from those estimates.

(G) REPURCHASE AGREEMENTS.  The Fund may enter into repurchase agreements to
earn income. The Fund may enter into repurchase agreements only with financial
institutions that are deemed by the Manager or Subadvisor to be creditworthy,
pursuant to guidelines established by the Fund's Board. Repurchase agreements
are considered under the 1940 Act to be collateralized loans by a Fund to the
seller secured by the securities transferred to the Fund.

When the Fund invests in repurchase agreements, the Fund's custodian takes
possession of the collateral pledged for investments in such repurchase
agreements. The underlying collateral is valued daily on a mark-to-market basis
to determine that the value, including accrued interest, exceeds the repurchase
price. In the event of the seller's default of the obligation to repurchase, the
Fund has the right to liquidate the collateral and apply the proceeds in
satisfaction of the obligation. Under certain circumstances, in the event of
default or bankruptcy by the other party to the agreement, realization and/or
retention of the collateral may be subject to legal proceedings and possible
realized loss to the Fund.

(H) FOREIGN CURRENCY TRANSACTIONS.  The books and records of the Fund are kept
in U.S. dollars. Prices of securities denominated in foreign currency amounts
are translated into U.S. dollars at the mean between the buying and selling
exchange rates last quoted by any major U.S. bank at the following dates:

(i) market value of investment securities, other assets and liabilities--at the
    valuation date, and

(ii) purchases and sales of investment securities, income and expenses--at the
     date of such transactions.

The assets and liabilities that are denominated in foreign currency amounts are
presented at the exchange rates and market values at the close of the period.
The realized and unrealized changes in net assets arising from fluctuations in
exchange rates and market prices of securities are not separately presented.

Net realized gain (loss) on foreign currency transactions represents net gains
and losses on foreign currency forward contracts, net currency gains or losses
realized as a result of differences between the amounts of securities sale
proceeds or purchase cost, dividends, interest and withholding taxes as recorded
on the Fund's books, and the U.S. dollar equivalent amount actually received or
paid. Net currency gains or losses from valuing such foreign currency
denominated assets and liabilities, other than investments at valuation date
exchange rates, are reflected in unrealized foreign exchange gains or losses.

(I) SECURITIES LENDING.  In order to realize additional income, the Fund may
engage in securities lending, subject to the limitations set forth in the 1940
Act, and relevant guidance by the staff of the Securities and Exchange
Commission. In the event the Fund does engage in securities lending, the Fund
will lend through its custodian, State Street Bank and Trust Company ("State
Street"). State Street will manage the Fund's cash collateral in accordance with
the Lending Agreement between the Fund and State Street, and indemnify the
Fund's portfolio against counterparty risk. The loans will be collateralized by
cash or securities at least equal at all times to the market value of the
securities loaned. Collateral will consist of U.S. Government securities, cash
equivalents or irrevocable letters of credit. The Fund may bear the risk of
delay in recovery of, or loss of rights in, the securities loaned should the
borrower of the securities experience financial difficulty. The Fund may also
record realized gain or loss on securities deemed sold due to a borrower's
inability to return securities on loan. The Fund will receive compensation for
lending its securities in the form of fees or retain a portion of interest on
the investment of any cash received as collateral. The Fund also will continue
to receive interest and dividends on the securities loaned and any gain or loss
in the market price of the securities loaned that may occur during the term of
the loan will be for the account of the Fund.

Although the Fund and New York Life Investments (as defined in Note 3(A)) have
temporarily suspended securities lending, the Fund and New York Life Investments
reserve the right to reinstitute lending when deemed

22    MainStay Epoch Global Choice Fund



appropriate. The Fund had no portfolio securities on loan as of April 30, 2010.

(J) REDEMPTION FEE.  Prior to April 1, 2010, the Fund imposed a 2.00% redemption
fee on redemptions (including exchanges) of Fund shares made within 60 days of
their date of purchase for any class. The redemption fee was designed to offset
brokerage commissions and other costs associated with short-term trading and was
not assessed on shares acquired through the reinvestment of dividends or
distributions paid by the Fund. The redemption fees are included in the
Statement of Changes in Net Assets' shares redeemed amount and retained by the
Fund.

(K) CONCENTRATION OF RISK.  The Fund may invest in foreign securities, which
carry certain risks that are in addition to the usual risks inherent in domestic
instruments. These risks include those resulting from currency fluctuations,
future adverse political and economic developments and possible imposition of
currency exchange blockages or other foreign governmental laws or restrictions.
These risks are likely to be greater in emerging markets than in developed
markets.

(L) INDEMNIFICATIONS.  Under the Trust's organizational documents, its officers
and trustees are indemnified against certain liabilities that may arise out of
performance of their duties to the Trust. Additionally, in the normal course of
business, the Fund enters into contracts with third-party service providers that
contain a variety of representations and warranties and which provide general
indemnifications. The Fund's maximum exposure under these arrangements is
unknown, as this would involve future claims that may be made against the Fund
that have not yet occurred. Based on experience, management is of the view that
the risk of loss in connection with these potential indemnification obligations
is remote. However, there can be no assurance that material liabilities related
to such obligations will not arise in the future, which could adversely impact
the Fund.

NOTE 3--FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER AND SUBADVISOR.  New York Life Investment Management LLC ("New York
Life Investments" or "Manager"), a registered investment adviser and an
indirect, wholly-owned subsidiary of New York Life Insurance Company ("New York
Life"), serves as the Fund's Manager, pursuant to a Management Agreement, as
amended ("Management Agreement"). The Manager provides offices, conducts
clerical, recordkeeping and bookkeeping services, and keeps most of the
financial and accounting records required to be maintained by the Fund. Except
for the portion of salaries and expenses that are the responsibility of the
Fund, the Manager also pays the salaries and expenses of all personnel
affiliated with the Fund and the operational expenses of the Fund. Epoch
Investment Partners, Inc. ("Epoch" or "Subadvisor"), a registered investment
adviser, serves as Subadvisor to the Fund and is responsible for the day-to-day
portfolio management of the Fund. Pursuant to the terms of a Subadvisory
Agreement between New York Life Investments and the Subadvisor, New York Life
Investments pays for the services of the Subadvisor.

The Fund pays the Manager a monthly fee for services performed and facilities
furnished at an annual rate of 1.00% of the Fund's average daily net assets.

Effective after the close of business on November 13, 2009, New York Life
Investments entered into a written expense limitation agreement under which it
has agreed to reimburse expenses of Class A and Class I shares so that the total
ordinary operating expenses (total ordinary operating expenses excludes taxes,
interest, litigation, extraordinary expenses, brokerage and other transaction
expense relating to the purchase or sale of portfolio investments and the fees
and expenses of any other funds in which the Fund invests) for Class A and Class
I shares do not exceed the following percentages of average daily net assets,
Class A, 1.54% and Class I, 1.29%. These expense limitations were based on the
total annual operating expenses of the predecessor fund (adjusted to reflect any
applicable expense limitation agreement.) New York Life Investments will apply
an equivalent waiver or reimbursement, in an amount equal to the number of basis
points waived for Class A shares, to Investor Class and Class C shares of the
Fund. This agreement will be in effect for a two-year period unless extended by
New York Life Investments and approved by the Fund's Board in connection with
its review of the Fund's investment advisory agreement. Based on its review, the
Board may maintain, modify or terminate the agreement.

Prior to the close of business on November 13, 2009, Epoch had a written expense
limitation agreement under which it had agreed to waive a portion of the
Predecessor Fund's management fee or reimburse the expenses of the appropriate
class of the Predecessor Fund so that the class' total ordinary operating
expenses did not exceed the following percentages of average daily net assets
for each class: Class A, 1.54%; and Class I, 1.29%. The agreement did not apply
to interest, taxes, brokerage commissions, other expenditures capitalized in
accordance with generally accepted accounting principles or other extraordinary
expenses not incurred in the ordinary course of business. The total amount of
reimbursement recoverable by Epoch was the sum of all fees previously waived or
reimbursed by Epoch to the Predecessor Fund during any of the previous three (3)
years, less any reimbursement previously paid by the Predecessor Fund to Epoch
with respect to any waivers, reductions, and payments made.

For the four-month period ended April 30, 2010, New York Life Investments earned
fees from the Fund in the amount of $183,215 and waived its fees in the amount
of $54,589.

State Street, 1 Lincoln Street, Boston, Massachusetts 02111, provides sub-
administration and sub-accounting services to the Fund pursuant to an agreement
with New York Life Investments. These services include calculating the daily
NAVs of the Fund, maintaining the general ledger and sub-ledger accounts for the
calculation of the Fund's respective NAVs, and assisting New York Life
Investments in conducting various aspects of the Fund's administrative
operations. For providing these services to the Fund, State Street is

(B) DISTRIBUTION AND SERVICE FEES.  Effective after the close of business on
November 13, 2009, the Trust, on behalf of the Fund, has entered into a
Distribution Agreement with NYLIFE Distributors LLC (the "Distributor"), an
indirect, wholly-owned subsidiary of New York Life. The Fund has adopted
distribution and service plans, (the "Plans") in accordance with the provisions
of Rule 12b-1 under the 1940 Act.

Pursuant to the Investor Class and Class A Plans, the Distributor receives a
monthly distribution fee from the Fund at an annual rate of 0.25% of the average
daily net assets of the Fund's Investor Class and Class A shares, which is an
expense of the Investor Class and Class A shares of the Fund for distribution or
service activities as designated by the Distributor. Pursuant to the Class C
Plan, the Fund pays the Distributor a monthly distribution fee, which is an
expense of the Class C shares of the Fund, at an annual rate of 0.75% of the
average daily net assets of the Fund's Class C shares, along with a shareholder
service fee at an annual rate of 0.25% of the average daily net asset value of
the Class C shares of the Fund for a total 12b-1 fee of 1.00%. Class I shares
are not subject to a distribution or service fee.

The Plans provide that the distribution and service fees are payable to the
Distributor regardless of the amounts actually expended by the Distributor for
distribution of the Fund's shares and service activities.

(C) SALES CHARGES.  The Fund was advised by the Distributor that the amount of
sales charges retained on sales of Investor Class and Class A shares were $299
and $654, respectively, for the four-month period ended April 30, 2010 .

(D)  TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT.   NYLIM
Service Company LLC, an affiliate of New York Life Investments, is the Fund's
transfer, dividend disbursing and shareholder servicing agent pursuant to an
agreement between NYLIM Service Company LLC and the Trust. NYLIM Service Company
LLC has entered into an agreement with Boston Financial Data Services, Inc.
("BFDS") pursuant to which BFDS performs certain transfer agent services on
behalf of NYLIM Service Company LLC. Transfer agent expenses incurred by the
Fund for the four-month period ended April 30, 2010, were as follows:

<Table>

- ----------------------------------------------

</Table>


(E) SMALL ACCOUNT FEE.  Shareholders with small accounts adversely impact the
cost of providing transfer agency services. In an effort to reduce total
transfer agency expenses, the Fund has implemented a small account fee on
certain types of accounts. Certain shareholders with an account balance of less
than $1,000 are charged an annual per account fee of $20 (assessed semi-
annually). These fees are included in transfer agent fees shown on the Statement
of Operations.

(F) CAPITAL.  At April 30, 2010, New York Life and its affiliates beneficially
held shares of the Fund with the following values and percentages of net assets
as follows:

services provided to the Fund by the Office of the General Counsel of New York

carryforwards of $8,339,809 were available as shown in the table below, to the

The line of credit is in the amount of $125,000,000 and the commitment fee rate
is an annual rate of 0.10% of the average commitment amount, plus a 0.04% up-
front payment payable, regardless of usage, to The Bank of New York Mellon,

NOTE 10--REORGANIZATION:

At a special meeting held on October 30, 2009, the shareholders of the Epoch
U.S. All Cap Equity Fund approved the reorganization of the Epoch U.S. All Cap
Equity Fund with and into MainStay Epoch Global Choice Fund. Effective after the
close of business on November 13, 2009, the Class P shares of Epoch U.S. All Cap

redesignated as Class I shares of MainStay Epoch Global Choice Fund. Investor
Class and Class C shares were seeded as of the close of business on November 13,

NOTE 11--NEW ACCOUNTING PRONOUNCEMENT:

In January 2010, the Financial Accounting Standards Board ("FASB") issued
Accounting Standards Update ("ASU") No. 2010-06 "Improving Disclosures about
Fair Value Measurements." ASU 2010-06 requires reporting entities to make new
disclosures about amount and reasons for significant transfers in and out of
Level 1 and Level 2 fair value measurements and input and valuation techniques
used to measure fair value for both recurring and nonrecurring fair value

        MESSAGE FROM THE PRESIDENT AND SEMIANNUAL REPORT

        Unaudited - April 30, 2010



MESSAGE FROM THE PRESIDENT

During the six months ended April 30, 2010, stock and bond markets generally
advanced, despite some volatility in January and February. Domestic small-cap
stocks were particularly strong, and U.S. stocks at all capitalization levels
provided double digit returns. Value stocks outpaced growth stocks for companies
of all sizes during this period.

International stocks provided positive returns overall, but results varied
widely by country. Concerns about Greece's ability to meet its debt obligations
led many investors to abandon their holdings in Greece and question their
investments in several peripheral European nations where perceived risk had
increased. For the six months ended April 30, 2010, equities in the Far East
(including Japan) tended to be stronger than those in Europe.

The economic recovery in the United States continued. Real gross domestic
product advanced in the first quarter of 2010, though at a slower pace than in
the fourth quarter of 2009. The Federal Open Market Committee kept the targeted
federal funds rate at a historically low level throughout the six-month period,
which prompted many investors to leave the safety of U.S. Treasury securities in
search of higher yield.

In the high-yield bond market, lower-rated credits tended to be the strongest
performers. With investment-grade investors crossing into high-yield territory,
however, the highest-rated high-yield credits also saw strong demand. In the
municipal market, new-issue supply was reduced by government incentives that
encouraged municipal issuers to raise funds in the taxable market. In the
leveraged-loan market, new issuance strengthened, but extensive repayments
caused the market as a whole to contract.


During the period covered by this report, MainStay's portfolio managers sought
to make the most of market conditions within the investment strategies and risk
parameters of their respective Funds. While individual markets and Fund results
may vary, our pursuit of competitive returns over full market cycles has never
changed.

The information that follows provides a closer look
at the securities, strategies and market conditions that affected your MainStay
Fund(s) during the period covered by this report. Of course, past performance is
no guarantee of future results. Even in a rising market, we believe that
maintaining a long-term perspective can be valuable. At MainStay, we believe
that in all markets, broad diversification, gradual allocation adjustments and
regular portfolio reviews can help guide you toward your long-range financial
goals.

We thank you for choosing MainStay Funds, and we look forward to serving your
investment needs for many years to come.

Sincerely,

/s/ STEPHEN P. FISHER

Stephen P. Fisher
President

1. Performance tables and graphs do not reflect the deduction of the taxes that
   a shareholder would pay on distribution or Fund-share redemptions. Total
   returns reflect maximum applicable sales charges explained in this paragraph,
   change in share price, and reinvestment of dividend and capital gain
   distributions. The graphs assume an initial investment of $25,000 for Class A
   shares and $10,000 for all other classes and reflect the deduction of all
   sales charges that would have applied for the period of investment. Class A
   shares generally have a $25,000 minimum initial investment with no minimum
   subsequent purchase amount. For investors that, in the aggregate, have assets
   of $100,000 or more invested in any share classes of any of the MainStay
   Funds, the minimum initial investment is $15,000. Investor Class and Class A
   shares are sold with a maximum initial sales charge of 5.5% and an annual
   12b-1 fee of 0.25%. Class C shares are sold with no initial sales charge and
   are subject to a contingent deferred sales charge ("CDSC") of 1.00%. Class I
   shares are sold with no initial sales charge or CDSC, have no annual 12b-1
   fee, and are generally available to corporate and institutional investors or
   individual investors with a minimum initial investment of $5 million.
   Performance figures reflect certain fee waivers and/or expense limitations,
   without which total returns would have been lower. For information on current
   fee waivers and/or expense limitations, please refer to the notes to the
   financial statements. The Fund is the successor to the Epoch Global Equity
   Shareholder Yield Fund. Effective January 4, 2010, the Fund changed its
   fiscal year end from December 31 to October 31.
2. Performance figures for Investor Class and Class C shares, first offered
   November 16, 2009, include the historical performance of Class I shares
   through November 13, 2009 adjusted for differences in certain contractual
   expenses and fees.

   following 23 developed market country indices: Australia, Austria, Belgium,
   Canada, Denmark, Finland, France, Germany, Greece, Hong Kong, Ireland, Italy,
   Japan, Netherlands, New Zealand, Norway, Portugal, Singapore, Spain, Sweden,
   Switzerland, the United Kingdom and the United States, Total returns assume
   reinvestment of all dividends and capital gains. The Fund has selected the
   MSCI World Index in replacement of the S&P Developed BMI Index as its broad-
   based securities market index for comparison purposes because it believes the
   MSCI World Index is more reflective of the Fund's current investment style.
   An investment cannot be made directly in an index.
5. The S&P Developed BMI Index is a subset of the S&P Global BMI Index which is
   an unmanaged index measuring global stock market performance covering
   approximately 11,000 companies in 46 countries. The S&P Developed BMI Index
   represents the 25 developed markets within the broader Index. Total returns
   assume reinvestment of all dividends and capital gains. An investment cannot
   be made directly in an index.
6. The average Lipper global multi-cap value fund is representative of funds
   that, by portfolio practice, invest in a variety of market capitalization
   ranges without concentrating 75% of their equity assets in any one market
   capitalization range over an extended period of time. Global multi-cap value
   funds typically have a below-average price-to-cash flow ratio, price-to book
   ratio, and three-year sales-per-share growth value compared to the
   S&P/Citigroup BMI Index. This benchmark is a product of Lipper Inc. Lipper
   Inc. is an independent monitor of fund performance. Results are based on
   total returns with all dividend and capital gain distributions reinvested.

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY EPOCH GLOBAL EQUITY YIELD
FUND (UNAUDITED)
- --------------------------------------------------------------------------------

The example below is intended to describe the fees and expenses borne by
shareholders during the six-month period from November 1, 2009, to April 30,
2010, and the impact of those costs on your investment.

EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, exchange fees, and sales charges (loads) on
purchases (as applicable), and (2) ongoing costs, including management fees,
distribution and/or service (12b-1) fees, and other Fund expenses (as
applicable). This example is intended to help you understand your ongoing costs
(in dollars) of investing in the Fund and to compare these costs with the
ongoing costs of investing in other mutual funds. The example is based on an
investment of $1,000 made at the beginning of the six-month period and held for
the entire period from November 1, 2009, to April 30, 2010.

This example illustrates your Fund's ongoing costs in two ways:

- - ACTUAL EXPENSES
The second and third data columns in the table below provide information about
actual account values and actual expenses. You may use the information in these
columns, together with the amount you invested, to estimate the expenses that
you paid during the six-months ended April 30, 2010. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number under the heading entitled "Expenses Paid
During Period" to estimate the expenses you paid on your account during this
period.

- - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The fourth and fifth data columns in the table below provide information about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense ratio and an assumed rate of return of 5% per year before expenses,
which is not the Fund's actual return. The hypothetical account values and
expenses may not be used to estimate the actual ending account balances or
expenses you paid for the six-month period shown. You may use this information
to compare the ongoing costs of investing in the Fund with the ongoing costs of
investing in other Funds. To do so, compare this 5% hypothetical example with
the 5% hypothetical examples that appear in the shareholder reports of the other
Funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as
redemption fees, if applicable, exchange fees, or sales charges (loads).
Therefore, the fourth and fifth data columns of the table are useful in
comparing ongoing costs only and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.

1. Expenses are equal to the Fund's annualized expense ratio of each class
   (1.13% for Investor Class,1.20% for Class A, 1.89% for Class C and 0.95% for
   Class I) multiplied by the average account value over the period, divided by
   365 and multiplied by 181 days for Class A and Class I (to reflect the one-
   half year period) and 168 days for Investor Class and Class C (to reflect the
   since-inception period).The table above represents actual expenses incurred
   during the one-half year period.

2. Expenses paid during the period reflect ongoing costs for the period from
   inception through April 30, 2010. Had these shares been offered for the full
   six-month period ended April 30, 2010, and had the Fund provided a
   hypothetical 5% annualized return, expenses paid during the period would have
   been $5.66 for Investor Class and $9.44 for Class C and the ending account
   value would have been $1,019.20 for Investor Class and $1,015.40 for Class C.

3. Investor Class and Class C shares began investment operations on November 16,
   2009.

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS(1)


QUESTIONS ANSWERED BY PORTFOLIO MANAGERS ERIC SAPPENFIELD, WILLIAM PRIEST, CFA,
AND MICHAEL WELHOELTER, CFA, OF EPOCH INVESTMENT PARTNERS, INC. (EPOCH), THE
FUND'S SUBADVISOR.

HOW DID MAINSTAY EPOCH GLOBAL EQUITY YIELD FUND PERFORM RELATIVE TO ITS PEERS
AND ITS BENCHMARK FOR THE FOUR MONTHS ENDED APRIL 30, 2010?

Excluding all sales charges, MainStay Epoch Global Equity Yield Fund returned
1.12% for Investor Class shares, 1.11% for Class A shares and 0.89% for Class C
shares for the four months ended April 30, 2010. Over the same period, the
Fund's Class I shares returned 1.18%. All share classes underperformed the 3.11%
return of the average Lipper() global multi-cap value fund, the 3.25% return of
the MSCI World Index() and the 4.53% return of the S&P Developed BMI Index() for
the four months ended April 30, 2010. The MSCI World Index is the Fund's broad-
based securities-market index. See page 5 for Fund returns with sales charges.

WHAT MAJOR FACTORS AFFECTED THE FUND'S RELATIVE PERFORMANCE DURING THE FOUR-
MONTH REPORTING PERIOD?

During the four months ended April 30, 2010, market dynamics reflected
significant volatility, although equities finished the reporting period higher
overall. Positive forces included excellent corporate results (buoyed by
productivity gains and cost cutting) and a stronger U.S. dollar, especially
against the Eurozone. Market concerns included government economic intervention
and its impact on funding, the situation in Greece, the possibility of contagion
to other European nations, and China's efforts to contain inflation.

The Fund's exposure to utilities was a positive contributor to performance,
largely because of effective stock selection. Stock selection also added to
returns in the materials sector. The Fund also benefited from having a
significantly underweight position in health care stocks, which lagged the MSCI
World Index primarily because of evolving health care reform in the United
States. More than offsetting these positive factors, however, was the negative
effect of sizable exposure to higher-yielding but lagging sectors, such as
telecommunication services. The Fund's underweight position in industrials and
stock selection in less cyclical portions of the sector also detracted.

DURING THE REPORTING PERIOD, WHICH SECTORS MADE THE STRONGEST CONTRIBUTIONS TO
THE FUND'S ABSOLUTE PERFORMANCE AND WHICH SECTORS MADE THE WEAKEST
CONTRIBUTIONS?

On an absolute basis, the strongest-contributing sectors to the Fund's
performance were industrials, consumer discretionary and financials. Industrial
stocks were generally strong, as investor's remained optimistic about recovering
global activity. The consumer discretionary sector also performed well, as
consumer spending remained strong and the jobs market improved. Financials as a
whole generated strong returns on expectations that interest rates would remain
low and on moderating concerns about loan loss provisions.

During the reporting period, the sectors that detracted the most from the Fund's
absolute performance were telecommunication services, health care and energy.
The defensive nature of these sectors was the primary driver of the
underperformance.

WHICH INDIVIDUAL STOCKS WERE THE STRONGEST CONTRIBUTORS TO THE FUND'S ABSOLUTE
PERFORMANCE DURING THE REPORTING PERIOD AND WHICH STOCKS DETRACTED?

On an absolute basis, NYSE Euronext, Emerson Electric and Arthur J. Gallagher
made the strongest contributions to the Fund's performance. NYSE Euronext, a
global operator of financial markets and a provider of trading strategies
advanced during the reporting period as volumes in markets picked up. Shares of
Emerson Electric, a United States-based global technology and engineering
services company, rose on the prospect of increased global economic activity.
Arthur J. Gallagher, an insurance brokerage and claims settlement company,
benefited from high-quality earnings and increasing distributions to
shareholders.

Spain-based telecommunications and media company Telefonica, global oil services
company Diamond Offshore Drilling and electricity and gas provider National Grid
were among the largest detractors from the Fund's absolute performance.
Telefonica's stock suffered from the ripple effect of the debt crisis in Greece.
Diamond Offshore Drilling's shares declined on reports that the company had
decided to increase its offshore drilling interests and decrease its dividend
payout. National Grid was hurt by the general decline

1. Effective January 4, 2010, the Fund's fiscal year-end changed from December
   31 to October 31. As a result, the following discussion covers the four-month
   reporting period ended April 30, 2010.

in equity prices across Europe and by the foreign exchange translation effects
of a weaker British sterling.

DID THE FUND MAKE ANY SIGNIFICANT PURCHASES OR SALES DURING THE REPORTING
PERIOD?

Among the stocks that the Fund purchased during the reporting period were NYSE
Euronext, Taiwan-based information technology company Quanta
Computer and pharmaceutical company Abbott Laboratories. We established a Fund
position in NYSE Euronext to take advantage of increased market volumes and the
company's broad reach as an operator of market exchanges around the globe. At
the time of purchase, Quanta Computer offered a dividend payout in excess of 5%,
which we expected to be sup-ported by an improving global personal computer
cycle. We were attracted to Abbott Laboratories because the globally diversified
health care company is generating substantial free cash flow and focusing on
strengthening its balance sheet while maintaining a high dividend.

During the reporting period, we sold the Fund's positions in Germany-based
electricity and gas suppler RWE, Italy-based electricity operator Enel and
discount retailer Wal-Mart Stores. We sold these positions to reallocate capital
to better investments, such as those noted in the preceding paragraph.

HOW DID THE FUND'S WEIGHTINGS CHANGE DURING THE REPORTING PERIOD?

During the reporting period, we increased the Fund's weightings in the
financials, information technology and health care sectors. Within financials,
we added Fund positions in insurance companies Arthur J. Gallagher and Munich Re
and in U.S. bank Hudson Bancorp. In information technology, we established new
Fund positions in Microchip Technology and Quanta Computer and added to existing
positions in Taiwan Semiconductor Manufacturing Company and Redecard. We
increased the Fund's exposure to health care primarily by establishing a
position in Abbott Laboratories.

We reduced the Fund's exposure to the utilities, consumer staples and energy
sectors. In utilities, we sold the Fund's positions in Enel and RWE. In consumer
staples, we sold the Fund's positions in Kraft Foods, Supervalu and Wal-Mart
Stores. We reduced the Fund's allocation to energy primarily by trimming its
position in BP following the initial discovery an oil leak in the Gulf of
Mexico.

HOW WAS THE FUND POSITIONED AT THE END OF APRIL 2010?

As of April 30, 2010, the Fund's most substantially overweight sectors relative
to the MSCI World Index were utilities, telecommunication services and consumer
staples. The Fund's most substantially underweight sectors relative to the MSCI
World Index were financials, information technology and materials. We believe
the Fund is well positioned to achieve its goals of high income with lower
volatility. We believe that the strong balance sheets and growing cash flows
will prove valuable to investors over the long term.

NOTES TO FINANCIAL STATEMENTS UNAUDITED

NOTE 1--ORGANIZATION AND BUSINESS:

MainStay Funds Trust (the "Trust") is organized as a Delaware Statutory Trust
and is governed by a Declaration of Trust dated April 8, 2009. The Trust is
registered under the Investment Company Act of 1940, as amended (the "1940
Act"), as an open-end management investment company, and is comprised of twenty-
nine funds (collectively referred to as the "Funds"). These financial statements
and notes relate only to the MainStay Epoch Global Equity Yield Fund (the
"Fund"), a diversified fund. The Fund is the successor to the Epoch Global
Equity Shareholder Yield Fund (the "Predecessor Fund"), which was a series of a
different registered investment company for which Epoch Investment Partners,
Inc. served as investment adviser.

The Fund currently offers 4 classes of shares. Investor Class and Class C shares
were seeded as of the close of business on November 13, 2009 and were first
offered and commenced operations on November 16, 2009. Class I shares and Class
A shares commenced operations (under former designations) on December 27, 2005
and August 2, 2006, respectively. Effective, January 4, 2010, the Fund changed
its fiscal year end and tax year end from December 31 to October 31. Investor
Class and Class A shares are offered at net asset value ("NAV") per share plus
an initial sales charge. No sales charge applies on investments of $1 million or
more (and certain other qualified purchases) in Investor Class and Class A
shares, but a contingent deferred sales charge is imposed on certain redemptions
of such shares within one year of the date of purchase. Class C shares are
offered at NAV without an initial sales charge, although a 1.00% contingent
deferred sales charge may be imposed on redemptions made within one year of
purchase of Class C shares. Class I shares are offered at NAV and are not
subject to a sales charge. Depending upon eligibility, Investor Class shares may
convert to Class A shares and Class A shares may convert to Investor Class
shares. The four classes of shares have the same voting (except for issues that
relate solely to one class), dividend, liquidation and other rights, and the
same terms and conditions, except that Class C shares are subject to higher
distribution and/or service fee rates than Investor Class and Class A shares
under a distribution plan pursuant to Rule 12b-1 under the 1940 Act. Class I
shares are not subject to a distribution and/or service fee.

The Fund's investment objective is to seek to provide a high level of income.
Capital appreciation is a secondary investment objective.

The financial statements of the Fund reflect the historical results of the
Institutional Class and P shares of the Predecessor Fund prior to its
reorganization. (See Note 10.) Upon the completion of the reorganization, the
Class I and Class A shares of the Fund assumed the performance, financial and
other information of the Institutional Class and Class P shares, respectively.
All information regarding and references to periods prior to the commencement of
operations of the Fund refer to the Predecessor Fund.

NOTE 2--SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with accounting
principles generally accepted in the United States of America ("GAAP") and
follows the significant accounting policies described below.

(A) SECURITIES VALUATION.  Equity securities are valued at the latest quoted
sales prices as of the close of regular trading on the New York Exchange
("Exchange") (generally 4:00 p.m. Eastern time) on each day the Fund is open for
business ("valuation date"). Securities that are not traded on the valuation
date are valued at the mean of the latest quoted bid and asked prices. Prices
normally are taken from the principal market in which each security trades.
Investments in other mutual funds are valued at their NAVs as of the close of
the Exchange on the valuation date.

Temporary cash investments acquired over 60 days prior to maturity are valued
using the latest bid prices or using valuations based on a matrix system (which
considers such factors as security prices, yields, maturities, and ratings),
both as furnished by independent pricing services. Other temporary cash
investments which mature in 60 days or less ("short-term investments") are
valued at amortized cost. The amortized cost method involves valuing a security
at its cost on the date of purchase and thereafter assuming a constant
amortization to maturity of the difference between the principal amount due at
maturity and cost.

Securities for which market quotations are not readily available are valued by
methods deemed in good faith by the Fund's Board to represent fair value. Equity
and non-equity securities which may be valued in this manner include, but are
not limited to: (i) a security the trading for which has been halted or
suspended; (ii) a debt security that has recently gone into default and for
which there is not a current market quotation; (iii) a security of an issuer
that has entered into a restructuring; (iv) a security that has been de-listed
from a national exchange; (v) a security the market price of which is not
available from an independent pricing source or, if so provided, does not, in
the opinion of the Fund's Manager or Subadvisor, as defined in Note 3(A),
reflect the security's market value; and (vi) a security where the trading on
that security's principal market is temporarily closed at a time when, under
normal conditions, it would be open. At April 30, 2010, the Fund the Fund did
not hold securities that were valued in such a manner.

Certain events may occur between the time that foreign markets close, on which
securities held by the Fund principally trade, and the time at which the Fund's
NAV is calculated. These events may include, but are not limited to, situations
relating to a single issuer in a market sector, significant fluctuations in U.S.
or foreign markets, natural disasters, armed conflicts, governmental actions or
other

20    MainStay Epoch Global Equity Yield Fund



developments not tied directly to the securities markets. Should the Manager or
Subadvisor, as defined in Note 3(A), conclude that such events may have affected
the accuracy of the last price reported on the local foreign market, the Manager
or Subadvisor may, pursuant to procedures adopted by the Fund's Board, adjust
the value of the local price to reflect the impact on the price of such
securities as a result of such events. Additionally, international equity
securities are also fair valued whenever the movement of a particular index
exceeds certain thresholds. In such cases, the securities are fair valued by
applying factors provided by a third party vendor in accordance with the Fund's
policies and procedures. At April 30, 2010, certain foreign equity securities
held by the Fund were fair valued.

"Fair value" is defined as the price that the Fund would receive upon selling an
investment in an orderly transaction to an independent buyer in the principal or
most advantageous market of the investment. Fair value measurements are
determined within a framework that has established a three-tier hierarchy which
maximizes the use of observable market data and minimizes the use of
unobservable inputs to establish classification of fair value measurements for
disclosure purposes. "Inputs" refer broadly to the assumptions that market
participants would use in pricing the asset or liability, including assumptions
about risk, such as the risk inherent in a particular valuation technique used
to measure fair value using a pricing model and/or the risk inherent in the
inputs for the valuation technique. Inputs may be observable or unobservable.
Observable inputs are inputs that reflect the assumptions market participants
would use in pricing the asset or liability based on market data obtained from
sources independent of the reporting entity. Unobservable inputs are inputs that
reflect the reporting entity's own assumptions about the assumptions market
participants would use in pricing the asset or liability developed based on the
information available in the circumstances. The inputs or methodology used for
valuing securities may not be an indication of the risks associated with
investing in those securities. The three-tier hierarchy of inputs is summarized
in the three broad Levels listed below.

- - Level 1--quoted prices in active markets for identical investments

- - Level 2--other significant observable inputs (including quoted prices for
  similar investments in active markets, interest rates and yield curves,
  prepayment speeds, credit risks, etc.)

- - Level 3--significant unobservable inputs (including the Fund's own assumptions
  about the assumptions that market participants would use in determining the
  fair value of investments)

The aggregate value by input level, as of April 30, 2010, for the Fund's
investments is included at the end of the Fund's Portfolio of Investments.

The valuation techniques used by the Fund to measure fair value during the four-
month period ended April 30, 2010 maximized the use of observable inputs and
minimized the use of unobservable inputs. The Fund may have utilized some of the
following fair value techniques: multi-dimensional relational pricing models,
option adjusted spread pricing and estimating the price that would have
prevailed in a liquid market for an international equity security given
information available at the time of evaluation, when there are significant
events after the close of local foreign markets. For the four-month period ended
April 30, 2010, there have been no changes to the fair value methodologies.

(B) FEDERAL INCOME TAXES.  The Fund's policy is to comply with the requirements
of the Internal Revenue Code of 1986, as amended (the "Internal Revenue Code")
applicable to regulated investment companies and to distribute all of the
taxable income to the shareholders of the Fund within the allowable time limits.
Therefore, no federal income tax provision is required.

Investment income received by the Fund from foreign sources may be subject to
foreign income taxes. These foreign income taxes are generally withheld at the
source.

Management evaluates its tax positions to determine if the tax positions taken
meet the minimum recognition threshold in connection with accounting for
uncertainties in income tax positions taken or expected to be taken for the
purposes of measuring and recognizing tax liabilities in the financial
statements. Recognition of tax benefits of an uncertain tax position is required
only when the position is "more likely than not" to be sustained assuming
examination by taxing authorities. Management has analyzed the Fund's tax
positions taken on federal income tax returns for all open tax years (current
and prior three tax years), and has concluded that no provision for federal
income tax is required in the Fund's financial statements. The Fund's federal
and state income and federal excise tax returns for tax years for which the
applicable statutes of limitations have not expired are subject to examination
by the Internal Revenue Service and state departments of revenue.

(C) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS.  Dividends and distributions
are recorded on the ex-dividend date. The Fund intends to declare and pay
dividends of net investment income, if any, quarterly and distributions of net
realized capital and currency gains, if any, annually. Unless the shareholder
elects otherwise, all dividends and distributions are reinvested in the same
class of shares of the Fund, at NAV. Dividends and distributions to shareholders
are determined in accordance with federal income tax regulations and may differ
from GAAP.

(D) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  The Fund records security
transactions on the trade date. Realized gains and losses on security
transactions are determined using the identified cost method. Dividend income is
recognized on the ex-dividend date

NOTES TO FINANCIAL STATEMENTS UNAUDITED (CONTINUED)



and interest income is accrued as earned using the effective interest rate
method. Discounts and premiums on short-term investments are accreted and
amortized, respectively, on the straight-line method.

Investment income and realized and unrealized gains and losses on investments of
the Fund are allocated to separate classes of shares pro rata based upon their
relative net assets on the date the income is earned or realized and unrealized
gains and losses are incurred.

(E) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred, except where direct allocations of expenses can be made. Expenses
(other than transfer agent expenses and fees incurred under the shareholder
services plans and the distribution plans further discussed in Note 3(B)) are
allocated to separate classes of shares pro rata based upon their relative NAV
on the date the expenses are incurred. The expenses borne by the Fund, including
those of related parties to the Fund, are shown in the Statement of Operations.

(F) USE OF ESTIMATES.  In preparing financial statements in conformity with
GAAP, management makes estimates and assumptions that affect the reported
amounts and disclosures in the financial statements. Actual results could differ
from those estimates.

(G) REPURCHASE AGREEMENTS.  The Fund may enter into repurchase agreements to
earn income. The Fund may enter into repurchase agreements only with financial
institutions that are deemed by the Manager or Subadvisor to be creditworthy,
pursuant to guidelines established by the Fund's Board. Repurchase agreements
are considered under the 1940 Act to be collateralized loans by a Fund to the
seller secured by the securities transferred to the Fund.

When the Fund invests in repurchase agreements, the Fund's custodian takes
possession of the collateral pledged for investments in such repurchase
agreements. The underlying collateral is valued daily on a mark-to-market basis
to determine that the value, including accrued interest, exceeds the repurchase
price. In the event of the seller's default of the obligation to repurchase, the
Fund has the right to liquidate the collateral and apply the proceeds in
satisfaction of the obligation. Under certain circumstances, in the event of
default or bankruptcy by the other party to the agreement, realization and/or
retention of the collateral may be subject to legal proceedings and possible
realized loss to the Fund.

(H) FOREIGN CURRENCY TRANSACTIONS.  The books and records of the Fund are kept
in U.S. dollars. Prices of securities denominated in foreign currency amounts
are translated into U.S. dollars at the mean between the buying and selling
exchange rates last quoted by any major U.S. bank at the following dates:

(i) market value of investment securities, other assets and liabilities--at the
    valuation date, and

(ii) purchases and sales of investment securities, income and expenses--at the
     date of such transactions.

The assets and liabilities that are denominated in foreign currency amounts are
presented at the exchange rates and market values at the close of the period.
The realized and unrealized changes in net assets arising from fluctuations in
exchange rates and market prices of securities are not separately presented.

Net realized gain (loss) on foreign currency transactions represents net gains
and losses on foreign currency forward contracts, net currency gains or losses
realized as a result of differences between the amounts of securities sale
proceeds or purchase cost, dividends, interest and withholding taxes as recorded
on the Fund's books, and the U.S. dollar equivalent amount actually received or
paid. Net currency gains or losses from valuing such foreign currency
denominated assets and liabilities, other than investments at valuation date
exchange rates, are reflected in unrealized foreign exchange gains or losses.

(I) SECURITIES LENDING.  In order to realize additional income, the Fund may
engage in securities lending, subject to the limitations set forth in the 1940
Act, and relevant guidance by the staff of the Securities and Exchange
Commission. In the event the Fund does engage in securities lending, the Fund
will lend through its custodian, State Street Bank and Trust Company ("State
Street"). State Street will manage the Fund's cash collateral in accordance with
the Lending Agreement between the Fund and State Street, and indemnify the
Fund's portfolio against counterparty risk. The loans will be collateralized by
cash or securities at least equal at all times to the market value of the
securities loaned. Collateral will consist of U.S. Government securities, cash
equivalents or irrevocable letters of credit. The Fund may bear the risk of
delay in recovery of, or loss of rights in, the securities loaned should the
borrower of the securities experience financial difficulty. The Fund may also
record realized gain or loss on securities deemed sold due to a borrower's
inability to return securities on loan. The Fund will receive compensation for
lending its securities in the form of fees or retain a portion of interest on
the investment of any cash received as collateral. The Fund also will continue
to receive interest and dividends on the securities loaned and any gain or loss
in the market price of the securities loaned that may occur during the term of
the loan will be for the account of the Fund.

Although the Fund and New York Life Investments (as defined in Note 3(A)) have
temporarily suspended securities lending, the Fund and New York Life Investments
reserve the right to reinstitute lending when deemed

22    MainStay Epoch Global Equity Yield Fund



appropriate. The Fund had no portfolio securities on loan as of April 30, 2010.

(J) REDEMPTION FEE.  Prior to April 1, 2010, the Fund imposed a 2.00% redemption
fee on redemptions (including exchanges) of Fund shares made within 60 days of
their date of purchase for any class. The redemption fee was designed to offset
brokerage commissions and other costs associated with short-term trading and was
not assessed on shares acquired through the reinvestment of dividends or
distributions paid by the Fund. The redemption fees are included in the
Statement of Changes in Net Assets' shares redeemed amount and retained by the
Fund.

(L) CONCENTRATION OF RISK.  The Fund invests in foreign securities, which carry
certain risks that are in addition to the usual risks inherent in domestic
instruments. These risks include those resulting from currency fluctuations,
future adverse political and economic developments and possible imposition of
currency exchange blockages or other foreign governmental laws or restrictions.
These risks are likely to be greater in emerging markets than in developed
markets. The ability of issuers of debt securities held by the Fund to meet
their obligations may be affected by economic or political developments in a
specific country, industry or region.

(K) INDEMNIFICATIONS.  Under the Trust's organizational documents, its officers
and trustees are indemnified against certain liabilities that may arise out of
performance of their duties to the Trust. Additionally, in the normal course of
business, the Fund enters into contracts with third-party service providers that
contain a variety of representations and warranties and which provide general
indemnifications. The Fund's maximum exposure under these arrangements is
unknown, as this would involve future claims that may be made against the Fund
that have not yet occurred. Based on experience, management is of the view that
the risk of loss in connection with these potential indemnification obligations
is remote. However, there can be no assurance that material liabilities related
to such obligations will not arise in the future, which could adversely impact
the Fund.

(L) LARGE TRANSACTION RISKS.  From time to time, the Fund may receive large
purchase or redemption orders from affiliated or unaffiliated mutual funds or
other investors. Such large transactions could have adverse effects on a Fund's
performance if the Fund were required to sell securities or invest cash at times
when it otherwise would not do so. This activity could also accelerate the
realization of capital gains and increase the Fund's transaction costs. The Fund
has adopted procedures designed to mitigate the negative impacts of such large
transactions, but there can be no assurance that these procedures will be
effective.

indirect, wholly-owned subsidiary of New York Life Insurance Company ("New York
Life"), serves as the Fund's Manager, pursuant to a Management Agreement, as
amended ("Management Agreement"). The Manager provides offices, conducts
clerical, recordkeeping and bookkeeping services, and keeps most of the
financial and accounting records required to be maintained by the Fund. Except
for the portion of salaries and expenses that are the responsibility of the
Fund, the Manager also pays the salaries and expenses of all personnel
affiliated with the Fund and the operational expenses of the Fund. Epoch
Investment Partners, Inc. ("Epoch" or "Subadvisor"), a registered investment
adviser, serves as Subadvisor to the Fund and is responsible for the day-to-day
portfolio management of the Fund. Pursuant to the terms of a Subadvisory
Agreement between New York Life Investments and the Subadvisor, New York Life
Investments pays for the services of the Subadvisor.

The Fund pays the Manager a monthly fee for services performed and facilities
furnished at an annual rate of 0.70% of the Fund's average daily net assets.

Effective after the close of business on November 13, 2009, New York Life
Investments entered into a written expense limitation agreement under which it
has agreed to reimburse expenses of Class A and Class I Shares of the Fund so
that the total ordinary operating expenses (total ordinary operating expenses
excludes taxes, interest, litigation, extraordinary expenses, brokerage and
other transaction expense relating to the purchase or sale of portfolio
investments and the fees and expenses of any other funds in which the Fund
invests) for Class A and Class I do not exceed the following percentages of
average daily net assets, Class A, 1.24% and Class I, 0.99%. These expense
limitations were based on the total annual operating expenses of the predecessor
fund (adjusted to reflect any applicable expense limitation agreement.) New York
Life Investments will apply an equivalent waiver or reimbursement, in an amount
equal to the number of basis points waived for Class A shares, to Investor Class
and Class C shares of the Fund. This agreement will be in effect for a two-year
period unless extended by New York Life Investments and approved by the Fund's
Board in connection with its review of the Fund's investment advisory agreement.
Based on its review, the Board may maintain, modify or terminate the agreement.

For the four-month period ended April 30, 2010, New York Life Investments earned
fees from the Fund in the amount of $908,499 and waived its fees in the amount
of $31,442.

indirect, wholly-owned subsidiary of New York Life. The Fund has adopted
distribution and service plans, (the "Plans") in accordance with the provisions
of Rule 12b-1 under the 1940 Act.

Pursuant to the Investor Class and Class A Plans, the Distributor receives a
monthly distribution fee from each Fund at an annual rate of 0.25% of the
average daily net assets of the Fund's Investor Class and Class A shares, which
is an expense of the Investor Class and Class A shares of the respective Funds
for distribution or service activities as designated by the Distributor.
Pursuant to the Class C Plan, each Fund pays the Distributor a monthly
distribution fee, which is an expense of the Class C shares of the Fund, at an
annual rate of 0.75% of the average daily net assets of the respective Fund's
Class C shares, along with a shareholder service fee at an annual rate of 0.25%
of the average daily net assets of the Class C shares of the Fund for a total
12b-1 fee of 1.00%. Class I shares are not subject to a distribution or service
fee.

The Plans provide that the distribution and service fees are payable to the
Distributor regardless of the amounts actually expended by the Distributor for
distribution of the Fund's shares and service activities.

(C) SALES CHARGES.  The Fund was advised by the Distributor that the amount of
sales charges retained on sales of Investor Class and Class A shares were $251
and $3,234, respectively, for the four-month period ended April 30, 2010.

cost of providing transfer agency services. In an effort to reduce total
transfer agency expenses, the Fund has implemented a small account fee on

        MESSAGE FROM THE PRESIDENT AND SEMIANNUAL REPORT

        Unaudited - April 30, 2010



MESSAGE FROM THE PRESIDENT

During the six months ended April 30, 2010, stock and bond markets generally
advanced, despite some volatility in January and February. Domestic small-cap
stocks were particularly strong, and U.S. stocks at all capitalization levels
provided double digit returns. Value stocks outpaced growth stocks for companies
of all sizes during this period.

International stocks provided positive returns overall, but results varied
widely by country. Concerns about Greece's ability to meet its debt obligations
led many investors to abandon their holdings in Greece and question their
investments in several peripheral European nations where perceived risk had
increased. For the six months ended April 30, 2010, equities in the Far East
(including Japan) tended to be stronger than those in Europe.

The economic recovery in the United States continued. Real gross domestic
product advanced in the first quarter of 2010, though at a slower pace than in
the fourth quarter of 2009. The Federal Open Market Committee kept the targeted
federal funds rate at a historically low level throughout the six-month period,
which prompted many investors to leave the safety of U.S. Treasury securities in
search of higher yield.

In the high-yield bond market, lower-rated credits tended to be the strongest
performers. With investment-grade investors crossing into high-yield territory,
however, the highest-rated high-yield credits also saw strong demand. In the
municipal market, new-issue supply was reduced by government incentives that
encouraged municipal issuers to raise funds in the taxable market. In the
leveraged-loan market, new issuance strengthened, but extensive repayments
caused the market as a whole to contract.


During the period covered by this report, MainStay's portfolio managers sought
to make the most of market conditions within the investment strategies and risk
parameters of their respective Funds. While individual markets and Fund results
may vary, our pursuit of competitive returns over full market cycles has never
changed.

The information that follows provides a closer look
at the securities, strategies and market conditions that affected your MainStay
Fund(s) during the period covered by this report. Of course, past performance is
no guarantee of future results. Even in a rising market, we believe that
maintaining a long-term perspective can be valuable. At MainStay, we believe
that in all markets, broad diversification, gradual allocation adjustments and
regular portfolio reviews can help guide you toward your long-range financial
goals.

We thank you for choosing MainStay Funds, and we look forward to serving your
investment needs for many years to come.

Sincerely,

/s/ STEPHEN P. FISHER

Stephen P. Fisher
President

1. Performance tables and graphs do not reflect the deduction of the taxes that
   a shareholder would pay on distribution or Fund-share redemptions. Total
   returns reflect maximum applicable sales charges explained in this paragraph,
   change in share price, and reinvestment of dividend and capital gain
   distributions. The graphs assume an initial investment of $25,000 for Class A
   shares and $10,000 for all other classes and reflect the deduction of all
   sales charges that would have applied for the period of investment. Class A
   shares generally have a $25,000 minimum initial investment with no minimum
   subsequent purchase amount. For investors that, in the aggregate, have assets
   of $100,000 or more invested in any share classes of any of the MainStay
   Funds, the minimum initial investment is $15,000. Investor Class and Class A
   shares are sold with a maximum initial sales charge of 5.5% and an annual
   12b-1 fee of 0.25%. Class C shares are sold with no initial sales charge and
   are subject to a contingent deferred sales charge ("CDSC") of 1.00%. Class I
   shares are sold with no initial sales charge or CDSC, have no annual 12b-1
   fee, and are generally available to corporate and institutional investors or
   individual investors with a minimum initial investment of $5 million.
   Performance figures reflect certain fee waivers and/or expense limitations,
   without which total returns would have been lower. For information on current
   fee waivers and/or expense limitations, please refer to the notes to the
   financial statements. The Fund is the successor to the Epoch International
   Small Cap Fund. Effective January 4, 2010, the Fund changed its fiscal year

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY EPOCH INTERNATIONAL SMALL CAP
FUND (UNAUDITED)
- --------------------------------------------------------------------------------

The example below is intended to describe the fees and expenses borne by
shareholders during the six-month period from November 1, 2009, to April 30,
2010, and the impact of those costs on your investment.

EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, exchange fees, and sales charges (loads) on
purchases (as applicable), and (2) ongoing costs, including management fees,
distribution and/or service (12b-1) fees, and other Fund expenses (as
applicable). This example is intended to help you understand your ongoing costs
(in dollars) of investing in the Fund and to compare these costs with the
ongoing costs of investing in other mutual funds. The example is based on an
investment of $1,000 made at the beginning of the six-month period and held for
the entire period from November 1, 2009, to April 30, 2010.

This example illustrates your Fund's ongoing costs in two ways:

- - ACTUAL EXPENSES
The second and third data columns in the table below provide information about
actual account values and actual expenses. You may use the information in these
columns, together with the amount you invested, to estimate the expenses that
you paid during the six-months ended April 30, 2010. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number under the heading entitled "Expenses Paid
During Period" to estimate the expenses you paid on your account during this
period.

- - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The fourth and fifth data columns in the table below provide information about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense ratio and an assumed rate of return of 5% per year before expenses,
which is not the Fund's actual return. The hypothetical account values and
expenses may not be used to estimate the actual ending account balances or
expenses you paid for the six-month period shown. You may use this information
to compare the ongoing costs of investing in the Fund with the ongoing costs of
investing in other Funds. To do so, compare this 5% hypothetical example with
the 5% hypothetical examples that appear in the shareholder reports of the other
Funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as
redemption fees, if applicable, exchange fees, or sales charges (loads).
Therefore, the fourth and fifth data columns of the table are useful in
comparing ongoing costs only and will not help you determine the relative total

1. Expenses are equal to the Fund's annualized expense ratio of each class
   (1.64% for Investor Class, 1.70% for Class A, 2.40% for Class C and 1.45% for
   Class I) multiplied by the average account value over the period, divided by
   365 and multiplied by 181 days for Class A and Class I (to reflect the one-
   half year period) and 168 days for Investor Class and Class C (to reflect the
   since-inception period).The table above represents actual expenses incurred
   during the one-half year period.
2. Expenses paid during the period reflect ongoing costs for the period from
   inception through April 30, 2010. Had these shares been offered for the full
   six-month period ended April 30, 2010, and had the Fund provided a
   hypothetical 5% annualized return, expenses paid during the period would have
   been $8.20 for Investor Class and $11.98 for Class C and the ending account
   value would have been $1,016.70 for Investor Class and $1,012.90 for Class C.
3. Investor Class and Class C shares began investment operations on November 16,
   2009.

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS(1)

QUESTIONS ANSWERED BY PORTFOLIO MANAGERS EMILY BAKER, WILLIAM PRIEST, CFA, AND
MICHAEL WELHOELTER, CFA, OF EPOCH INVESTMENT PARTNERS, INC. (EPOCH), THE FUND'S
SUBADVISOR.

HOW DID MAINSTAY EPOCH INTERNATIONAL SMALL CAP FUND PERFORM RELATIVE TO ITS
PEERS AND ITS BENCHMARK FOR THE FOUR MONTHS ENDED APRIL 30, 2010?

Excluding all sales charges, MainStay Epoch International Small Cap Fund
returned 4.05% for Investor Class shares, 4.05% for Class A shares and 3.86% for
Class C shares for the four months ended April 30, 2010. Over the same period,
the Fund's Class I shares returned 4.13%. All share classes outperformed the
0.37% return of the average Lipper(2) international multi-cap core fund for the
same period. All share classes underperformed the 7.49% return of the MSCI World
Ex U.S. Small Cap Index(3) and the 5.10% return of the S&P EPAC Small Cap
Index(4) during the four months ended April 30, 2010. The MSCI World Ex U.S.
Small Cap Index is the Fund's broad-based securities-market index. See page 5
for Fund returns with sales charges.

WHAT MAJOR FACTORS INFLUENCED THE FUND'S RELATIVE PERFORMANCE DURING THE FOUR-
MONTH REPORTING PERIOD?

The first few months of 2010 proved to be highly volatile, as markets initially
turned negative on concerns over Chinese monetary tightening and European debt
concerns (particularly in Portugal, Ireland, Italy, Greece and Spain).
Gradually, a combination of improved macroeconomic data and evidence that
European troubles could be resolved and that China had made a strong policy move
resulted in a sharp market rally. Sentiment shifted again as news about the
Greek debt situation became less positive and doubts emerged about the
effectiveness of and timetable for related reforms. Despite this volatility,
international small caps performed well during the reporting period.

In addition, we saw encouraging signs of movement into a recovery in which
income and employment may start to grow more decisively. Corporate announcements
across the globe continued the trend of upside surprises. The strong momentum of
key leading indicators suggested that continued strong reporting may lie ahead.
These factors, along with attractive equity valuations, provided fundamental
positive underlying support for the market. Realizing that challenges may still
lie ahead, we have positioned the Fund with a focus on strong businesses that
generate a high level of reliable cash flow and that are run by management teams
with strong records of allocating capital to enhance shareholder value.

During the four months ended April 30, 2010, stock selection in the energy
sector contributed positively to the Fund's results relative to the MSCI World
Ex U.S. Small Cap Index. More specifically, the Fund's exposure to oil services
firms contributed meaningfully. For example, positions in Acergy, Technip and
Subsea outperformed the benchmark index, given their active exposure to the most
prolific, higher-growth offshore development regions. The Fund also benefited
from having an underweight position in financials.

More than offsetting these positive factors, however, were the detracting
effects of an overweight position in Europe, exposure to Brazilian stocks, and
weaker stock selection in the industrials sector. The Fund's overweight position
in Europe was adversely affected by debt concerns in several peripheral European
countries, which affected the entire region and drove the euro down against the
U.S. dollar. Brazilian stocks detracted from the Fund's performance relative to
the benchmark. Despite good fundamentals, the market suffered from variations in
Chinese commodity demand. Many of the Fund's Brazilian consumer discretionary
stocks, including home builders, autos and malls, paused during the reporting
period following significant gains in the fourth quarter of 2009. In the
industrials sector, the Fund's holdings in Italy and Spain particularly
struggled along with the broader equity markets in these countries.

DURING THE REPORTING PERIOD, WHICH SECTORS MADE THE STRONGEST CONTRIBUTIONS TO
THE FUND'S ABSOLUTE PERFORMANCE AND WHICH SECTORS MADE THE WEAKEST
CONTRIBUTIONS?

On an absolute basis, the strongest-contributing sectors to the Fund's
performance were energy, industrials and materials. In energy, Fund holdings in
oil services stocks particularly boosted Fund performance. In industrials, the
Fund saw strong results from companies with leading positions in their fields,
providers of productivity-improving services and companies involved in global
trade. In materials, stocks with exposure to precious metals, nonindustrial
metals and industrial gases helped the Fund's absolute performance.


1. Effective January 4, 2010, the Fund's fiscal year-end changed from December
   31 to October 31. As a result, the following discussion covers the four-month
   reporting period ended April 30, 2010.
2. See footnote on page 6 for more information on Lipper Inc.
3. See footnote on page 6 for more information on the MSCI World Ex U.S. Small
   Cap Index.

   Asia Composite) Small Cap Index.

                                                    mainstayinvestments.com    9



During the reporting period, the sectors that detracted most from the Fund's
absolute performance were financials, utilities and information technology. The
Fund had exposure to financial companies with businesses in southern Europe.
These companies suffered from contagion concerns stemming from the debt crisis
in Greece. Although the Fund had only limited exposure to utilities, Red
Electrica of Spain was one holding that felt the effects of Greek-contagion
concerns. We sold the Fund's position in Red Electrica during the reporting
period. In information technology, the Fund's position in Germany-based
electronic payment and risk management company Wirecard A.G. suffered when
negative rumors involving senior management circulated, causing extreme stock
price weakness.

WHICH INDIVIDUAL STOCKS WERE THE STRONGEST CONTRIBUTORS TO THE FUND'S ABSOLUTE
PERFORMANCE DURING THE REPORTING PERIOD AND WHICH STOCKS DETRACTED?

On an absolute basis, France-based specialty chemicals company Rhodia, U.K.-
based materials science company Cookson Group and Canada-based diversified
natural resource company Sherritt International made the strongest contributions
to the Fund's performance.

During the four-month reporting period, Wirecard A.G., Italy-based asset-
management company Azimut Holding and Greece-based financial services group EFG
Eurobank Ergasias were among the greatest detractors from the Fund's absolute
performance.

DID THE FUND MAKE ANY SIGNIFICANT PURCHASES OR SALES DURING THE REPORTING
PERIOD?

Among the stocks that the Fund purchased during the reporting period was
ProSiebenSat. 1 Media, a German broadcasting company. We bought the stock for
the Fund because of the company's free cash flow growth potential, since
advertising revenues are expected to pick up as the economy recovers. We also
established a Fund position in Canadian methanol company Methanex. We liked this
company's prospects for strong free cash flow growth as global activity
recovers.

In addition to the Fund's sales of Wirecard A.G. and Azimut Holding, we sold the
Fund's position in Unipol Gruppo Finanziario, an Italian holding company in the
financial sector. We sold the Fund's position on heightened concerns about the
extent of the Greek crisis. We also eliminated the Fund's holding in Cap Gemini,
a French consulting, outsourcing, technology and professional services company.
We sold the position when price appreciation took the stock out of the small-cap
universe.

HOW DID THE FUND'S WEIGHTINGS CHANGE DURING THE REPORTING PERIOD?

During the four months ended April 30, 2010, we increased the Fund's weightings
in the industrials, energy and materials sectors. We raised the Fund's weighting
in industrials to gain more Fund exposure to global economic growth. The
increased weighting in energy was driven primarily by the attractive valuations
of oil services companies. The Fund's exposure to materials rose through
investments in nonindustrial metals stocks that had lagged and offered an
attractive way to add more cyclicality to the Fund.

We reduced the Fund's exposure to the financials and information technology
sectors. Exposure to financials was lowered primarily by selling out of stocks
in the southern peripheral markets of Europe, which we felt would be adversely
affected by the troubles in Greece. We sold information technology stocks for
company-specific reasons and to raise capital to reinvest elsewhere.

HOW WAS THE FUND POSITIONED AT THE END OF APRIL 2010?

As of April 30, 2010, the Fund's most substantially overweight sectors relative
to the MSCI World Ex U.S. Small Cap Index were industrials, energy and health
care. As of the same date, the Fund's most substantially underweight sectors
relative to the MSCI World Ex U.S. Small Cap Index were financials, consumer
discretionary and materials.

NOTES TO FINANCIAL STATEMENTS UNAUDITED

NOTE 1--ORGANIZATION AND BUSINESS:

MainStay Funds Trust (the "Trust") is organized as a Delaware Statutory Trust
and is governed by a Declaration of Trust dated April 8, 2009. The Trust is
registered under the Investment Company Act of 1940, as amended (the "1940
Act"), as an open-end management investment company, and is comprised of twenty-
nine funds (collectively referred to as the "Funds"). These financial statements
and notes relate only to the MainStay Epoch International Small Cap Fund (the
"Fund"), a diversified fund. The Fund is the successor to the Epoch
International Small Cap Fund (the "Predecessor Fund"), which was a series of a
different registered investment company for which Epoch Investment Partners,
Inc. served as investment adviser.

The Fund currently offers 4 classes of shares. Investor Class and Class C shares
were seeded as of the close of business on November 13, 2009 and were first
offered and commenced operations on November 16, 2009. Class I shares and Class
A shares commenced operations (under former designations) on January 25, 2005
and August 2, 2006, respectively. Effective, January 4, 2010, the Fund changed
its fiscal year end and tax year end from December 31 to October 31. Investor
Class and Class A shares are offered at net asset value ("NAV") per share plus
an initial sales charge. No sales charge applies on investments of $1 million or
more (and certain other qualified purchases) in Investor Class and Class A
shares, but a contingent deferred sales charge is imposed on certain redemptions
of such shares within one year of the date of purchase. Class C shares are
offered at NAV without an initial sales charge, although a 1.00% contingent
deferred sales charge may be imposed on redemptions made within one year of
purchase of Class C shares. Class I shares are offered at NAV and are not
subject to a sales charge. Depending upon eligibility, Investor Class shares may
convert to Class A shares and Class A shares may convert to Investor Class
shares. The four classes of shares have the same voting (except for issues that
relate solely to one class), dividend, liquidation and other rights, and the
same terms and conditions, except that Class C shares are subject to higher
distribution and/or service fee rates than Investor Class and Class A shares
under a distribution plan pursuant to Rule 12b-1 under the 1940 Act. Class I
shares are not subject to a distribution and/or service fee.

The Fund's investment objective is to seek long-term capital appreciation.

The financial statements of the Fund reflect the historical results of the
Institutional Class and P shares of the Predecessor Fund prior to its
reorganization. (See Note 10.) Upon the completion of the reorganization, the
Class I and Class A shares of the Fund assumed the performance, financial and
other information of the Institutional Class and Class P shares, respectively of
the Predecessor Fund. All information regarding and references to periods prior
to the commencement of operations of the Fund refer to the Predecessor Fund.

NOTE 2--SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with accounting
principles generally accepted in the United States of America ("GAAP") and
follows the significant accounting policies described below.

(A) SECURITIES VALUATION.  Equity securities are valued at the latest quoted
sales prices as of the close of regular trading on the New York Exchange
("Exchange") (generally 4:00 p.m. Eastern time) on each day the Fund is open for
business ("valuation date"). Securities that are not traded on the valuation
date are valued at the mean of the latest quoted bid and asked prices. Prices
normally are taken from the principal market in which each security trades.
Investments in other mutual funds are valued at their NAVs as of the close of
the Exchange on the valuation date.

Temporary cash investments acquired over 60 days prior to maturity are valued
using the latest bid prices or using valuations based on a matrix system (which
considers such factors as security prices, yields, maturities, and ratings),
both as furnished by independent pricing services. Other temporary cash
investments which mature in 60 days or less ("short-term investments") are
valued at amortized cost. The amortized cost method involves valuing a security
at its cost on the date of purchase and thereafter assuming a constant
amortization to maturity of the difference between the principal amount due at
maturity and cost.

Securities for which market quotations are not readily available are valued by
methods deemed in good faith by the Fund's Board to represent fair value. Equity
and non-equity securities which may be valued in this manner include, but are
not limited to: (i) a security the trading for which has been halted or
suspended; (ii) a debt security that has recently gone into default and for
which there is not a current market quotation; (iii) a security of an issuer
that has entered into a restructuring; (iv) a security that has been de-listed
from a national exchange; (v) a security the market price of which is not
available from an independent pricing source or, if so provided, does not, in
the opinion of the Fund's Manager or Subadvisor, as defined in Note 3(A),
reflect the security's market value; and (vi) a security where the trading on
that security's principal market is temporarily closed at a time when, under
normal conditions, it would be open. At April 30, 2010, the Fund held a security
with a value of $1,441, that was valued in such a manner.

Certain events may occur between the time that foreign markets close, on which
securities held by the Fund principally trade, and the time at which the Fund's
NAV is calculated. These events may include, but are not limited to, situations
relating to a single issuer in a market sector, significant fluctuations in U.S.
or foreign markets, natural disasters, armed conflicts, governmental actions or
other

22    MainStay Epoch International Small Cap Fund



developments not tied directly to the securities markets. Should the Manager or
Subadvisor, as defined in Note 3(A),

conclude that such events may have affected the accuracy of the last price
reported on the local foreign market, the Manager or Subadvisor may, pursuant to
procedures adopted by the Fund's Board, adjust the value of the local price to
reflect the impact on the price of such securities as a result of such events.
Additionally, international equity securities are also fair valued whenever the
movement of a particular index exceeds certain thresholds. In such cases, the
securities are fair valued by applying factors provided by a third party vendor
in accordance with the Fund's policies and procedures. At April 30, 2010,
certain foreign equity securities held by the Fund were fair valued.

"Fair value" is defined as the price that the Fund would receive upon selling an
investment in an orderly transaction to an independent buyer in the principal or
most advantageous market of the investment. Fair value measurements are
determined within a framework that has established a three-tier hierarchy which
maximizes the use of observable market data and minimizes the use of
unobservable inputs to establish classification of fair value measurements for
disclosure purposes. "Inputs" refer broadly to the assumptions that market
participants would use in pricing the asset or liability, including assumptions
about risk, such as the risk inherent in a particular valuation technique used
to measure fair value using a pricing model and/or the risk inherent in the
inputs for the valuation technique. Inputs may be observable or unobservable.
Observable inputs are inputs that reflect the assumptions market participants
would use in pricing the asset or liability based on market data obtained from
sources independent of the reporting entity. Unobservable inputs are inputs that
reflect the reporting entity's own assumptions about the assumptions market
participants would use in pricing the asset or liability developed based on the
information available in the circumstances. The inputs or methodology used for
valuing securities may not be an indication of the risks associated with
investing in those securities. The three-tier hierarchy of inputs is summarized
in the three broad Levels listed below.

- - Level 1--quoted prices in active markets for identical investments

- - Level 2--other significant observable inputs (including quoted prices for
  similar investments in active markets, interest rates and yield curves,
  prepayment speeds, credit risks, etc.)

- - Level 3--significant unobservable inputs (including the Fund's own assumptions
  about the assumptions that market participants would use in determining the
  fair value of investments)

The aggregate value by input level, as of April 30, 2010, for the Fund's
investments is included at the end of the Fund's Portfolio of Investments.

The valuation techniques used by the Fund to measure fair value during the four-
month period ended April 30, 2010 maximized the use of observable inputs and
minimized the use of unobservable inputs. The Fund may have utilized some of the
following fair value techniques: multi-dimensional relational pricing models,
option adjusted spread pricing and estimating the price that would have
prevailed in a liquid market for an international equity security given
information available at the time of evaluation, when there are significant
events after the close of local foreign markets. For the four-month period ended
April 30, 2010, there have been no changes to the fair value methodologies.

Generally, a security is considered illiquid if it cannot be sold or disposed of
in the ordinary course of business at approximately the price at which it is
valued. Its illiquidity might prevent the sale of such security at a time when
the Manager or Subadvisor, if any, as defined in Note 3(A) might wish to sell,
and these securities could have the effect of decreasing the overall level of a
Fund's liquidity. Further, the lack of an established secondary market may make
it more difficult to value illiquid securities, requiring the Fund to rely on
judgments that may be somewhat subjective in determining value, which could vary
from the amount that the Fund could realize upon disposition. Difficulty in
selling illiquid securities may result in a loss or may be costly to the Fund.
Under the supervision of the Board, the Manager or Subadvisor, if any,
determines the liquidity of a Fund's investments; in doing so, the Manager or
Subadvisor, if any, may consider various factors, including (1) the frequency of
trades and quotations, (2) the number of dealers and prospective purchasers, (3)
the dealer undertakings to make a market, and (4) the nature of the security and
the market in which it trades (e.g., the time needed to dispose of the security,
the method of soliciting offers and the mechanics of transfer). Illiquid
securities generally will be valued in such manner, as the Board in good faith
deems appropriate to reflect their fair market value.

(B) FEDERAL INCOME TAXES.  The Fund's policy is to comply with the requirements
of the Internal Revenue Code of 1986, as amended (the "Internal Revenue Code")
applicable to regulated investment companies and to distribute all of the
taxable income to the shareholders of the Fund within the allowable time limits.
Therefore, no federal income tax provision is required.

Investment income received by the Fund from foreign sources may be subject to
foreign income taxes. These foreign income taxes are generally withheld at the
source.

Management evaluates its tax positions to determine if the tax positions taken
meet the minimum recognition threshold in connection with accounting for
uncertainties in income tax positions taken or expected to be taken for the
purposes of measuring and recognizing tax liabilities in the financial
statements. Recognition of tax benefits of an uncertain tax position is required
only when the position is

NOTES TO FINANCIAL STATEMENTS UNAUDITED (CONTINUED)



"more likely than not" to be sustained assuming examination by taxing
authorities. Management has analyzed the Fund's tax positions taken on federal
income tax returns for all open tax years (current and prior three tax years),
and has concluded that no provision for federal income tax is required in the
Fund's financial statements. The Fund's federal and state income and federal
excise tax returns for tax years for which the applicable statutes of
limitations have not expired are subject to examination by the Internal Revenue
Service and state departments of revenue.

(C) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS.  Dividends and distributions
are recorded on the ex-dividend date. The Fund intends to declare and pay
dividends of net investment income and distributions of net realized capital and
currency gains, if any, annually. Unless the shareholder elects otherwise, all
dividends and distributions are reinvested in the same class of shares of the
Fund, at NAV. Dividends and distributions to shareholders are determined in
accordance with federal income tax regulations and may differ from GAAP.

(D) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  The Fund records security
transactions on the trade date. Realized gains and losses on security
transactions are determined using the identified cost method. Dividend income is
recognized on the ex-dividend date and interest income is accrued as earned
using the effective interest rate method. Discounts and premiums on short-term
investments are accreted and amortized, respectively, on the straight-line
method.

Investment income and realized and unrealized gains and losses on investments of
the Fund are allocated to separate classes of shares pro rata based upon their
relative net assets on the date the income is earned or realized and unrealized
gains and losses are incurred.

(E) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred, except where direct allocations of expenses can be made. Expenses
(other than transfer agent expenses and fees incurred under the shareholder
services plans and the distribution plans further discussed in Note 3(B)) are
allocated to separate classes of shares pro rata based upon their relative NAV
on the date the expenses are incurred. The expenses borne by the Fund, including
those of related parties to the Fund, are shown in the Statement of Operations.

(F) USE OF ESTIMATES.  In preparing financial statements in conformity with
GAAP, management makes estimates and assumptions that affect the reported
amounts and disclosures in the financial statements. Actual results could differ
from those estimates.

(G) REPURCHASE AGREEMENTS.  The Fund may enter into repurchase agreements to
earn income. The Fund may enter into repurchase agreements only with financial
institutions that are deemed by the Manager or Subadvisor to be creditworthy,
pursuant to guidelines established by the Fund's Board. Repurchase agreements
are considered under the 1940 Act to be collateralized loans by a Fund to the
seller secured by the securities transferred to the Fund.

When the Fund invests in repurchase agreements, the Fund's custodian takes
possession of the collateral pledged for investments in such repurchase
agreements. The underlying collateral is valued daily on a mark-to-market basis
to determine that the value, including accrued interest, exceeds the repurchase
price. In the event of the seller's default of the obligation to repurchase, the
Fund has the right to liquidate the collateral and apply the proceeds in
satisfaction of the obligation. Under certain circumstances, in the event of
default or bankruptcy by the other party to the agreement, realization and/or
retention of the collateral may be subject to legal proceedings and possible
realized loss to the Fund.

(H) FOREIGN CURRENCY TRANSACTIONS.  The books and records of the Fund are kept
in U.S. dollars. Prices of securities denominated in foreign currency amounts
are translated into U.S. dollars at the mean between the buying and selling
exchange rates last quoted by any major U.S. bank at the following dates:

(i) market value of investment securities, other assets and liabilities--at the
    valuation date, and

(ii) purchases and sales of investment securities, income and expenses--at the
     date of such transactions.

The assets and liabilities that are denominated in foreign currency amounts are
presented at the exchange rates and market values at the close of the period.
The realized and unrealized changes in net assets arising from fluctuations in
exchange rates and market prices of securities are not separately presented.

Net realized gain (loss) on foreign currency transactions represents net gains
and losses on foreign currency forward contracts, net currency gains or losses
realized as a result of differences between the amounts of securities sale
proceeds or purchase cost, dividends, interest and withholding taxes as recorded
on the Fund's books, and the U.S. dollar equivalent amount actually received or
paid. Net currency gains or losses from valuing such foreign currency
denominated assets and liabilities, other than investments at valuation date
exchange rates, are reflected in unrealized foreign exchange gains or losses.

(I) SECURITIES LENDING.  In order to realize additional income, the Fund may
engage in securities lending, subject to the limitations set forth in the 1940
Act, and relevant guidance by the staff of the Securities and Exchange
Commission. In the event the Fund does engage in securities lending, the Fund
will lend through its custodian, State Street Bank and Trust Company ("State
Street"). State Street will manage the Fund's cash collateral in accordance with


24    MainStay Epoch International Small Cap Fund



the Lending Agreement between the Fund and State Street, and indemnify the
Fund's portfolio against counterparty risk. The loans will be collateralized by
cash or securities at least equal at all times to the market value of the
securities loaned. Collateral will consist of U.S. Government securities, cash
equivalents or irrevocable letters of credit. The Fund may bear the risk of
delay in recovery of, or loss of rights in, the securities loaned should the
borrower of the securities experience financial difficulty. The Fund may also
record realized gain or loss on securities deemed sold due to a borrower's
inability to return securities on loan. The Fund will receive compensation for
lending its securities in the form of fees or retain a portion of interest on
the investment of any cash received as collateral. The Fund also will continue
to receive interest and dividends on the securities loaned and any gain or loss
in the market price of the securities loaned that may occur during the term of
the loan will be for the account of the Fund.

Although the Fund and New York Life Investments (as defined in Note 3(A)) have
temporarily suspended securities lending, the Fund and New York Life Investments
reserve the right to reinstitute lending when deemed appropriate. The Fund had
no portfolio securities on loan as of April 30, 2010.

(J) REDEMPTION FEE.  Prior to April 1, 2010, the Fund imposed a 2.00% redemption
fee on redemptions (including exchanges) of Fund shares made within 60 days of
their date of purchase for any class. The redemption fee was designed to offset
brokerage commissions and other costs associated with short-term trading and was
not assessed on shares acquired through the reinvestment of dividends or
distributions paid by the Fund. The redemption fees are included in the
Statement of Changes in Net Assets' shares redeemed amount and retained by the
Fund.

(K) CONCENTRATION OF RISK  The Fund invests in foreign securities, which carry
certain risks that are in addition to the usual risks inherent in domestic
instruments. These risks include those resulting from currency fluctuations,
future adverse political and economic developments and possible imposition of
currency exchange blockages or other foreign governmental laws or restrictions.
These risks are likely to be greater in emerging markets than in developed
markets. The ability of issuers of debt securities held by the Fund to meet
their obligations may be affected by economic or political developments in a
specific country, industry or region.

(L) INDEMNIFICATIONS.  Under the Trust's organizational documents, its officers
and trustees are indemnified against certain liabilities that may arise out of
performance of their duties to the Trust. Additionally, in the normal course of
business, the Fund enters into contracts with third-party service providers that
contain a variety of representations and warranties and which provide general
indemnifications. The Fund's maximum exposure under these arrangements is
unknown, as this would involve future claims that may be made against the Fund
that have not yet occurred. Based on experience, management is of the view that
the risk of loss in connection with these potential indemnification obligations
is remote. However, there can be no assurance that material liabilities related
to such obligations will not arise in the future, which could adversely impact
the Fund.

(M) QUANTITATIVE DISCLOSURE OF DERIVATIVE HOLDINGS.  The following tables show
additional disclosures about the Fund's derivative and hedging activities,
including how such activities are accounted for and their effect on the Fund's
financial positions, performance and cash flows. These derivatives are not
accounted for as hedging instruments.

(2) Amount(s) represent(s) number of contracts or number of shares/units.

(N) LARGE TRANSACTION RISKS.  From time to time, the Fund may receive large
purchase or redemption orders from affiliated or unaffiliated mutual funds or
other investors. Such large transactions could have adverse effects on a Fund's
performance if the Fund were required to sell securities or invest cash at times
when it otherwise would not do so. This activity could also accelerate the
realization of capital gains and increase the Fund's transaction costs. The Fund
has adopted procedures designed to mitigate the negative impacts of such large
transactions, but there can be no assurance that these procedures will be
effective.

NOTE 3--FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER AND SUBADVISOR.  New York Life Investment Management LLC ("New York

of average daily net assets, Class A, 1.89% and Class I, 1.65%. These expense
limitations were based on the total annual operating expenses of the Predecessor
Fund (adjusted to reflect any applicable expense limitation agreement). New York
Life Investments will apply an equivalent waiver or reimbursement, in an amount
equal to the number of basis points waived for Class A shares, to Investor Class

period unless extended by New York Life Investments and approved by the Fund's
Board in connection with its review of the Fund's Investment advisory agreement.
Based on its review the Board may maintain, modify or terminate the agreement.

For the four-month period ended April 30, 2010, New York Life Investments earned
fees from the Fund in the amount of $649,111.

administration and sub-accounting services to the Fund pursuant to an agreement
with New York Life Investments. These services include calculating the daily
NAVs of the Fund, maintaining the general ledger and sub-ledger accounts for the
calculation of the Fund's respective NAVs, and assisting New York Life
Investments in conducting various aspects of the Fund's administrative
operations. For providing these services to the Fund, State Street is
compensated by New York Life Investments.

(B) DISTRIBUTION AND SERVICE FEES.  Effective after the close of business on
November 13, 2009, the Trust, on behalf of the Fund, entered into a Distribution
Agreement with NYLIFE Distributors LLC (the "Distributor"), an indirect, wholly-
owned subsidiary of New York Life. The Fund has adopted distribution and service
plans, (the "Plans") in accordance with the provisions of Rule 12b-1 under the
1940 Act.

Pursuant to the Investor Class and Class A Plans, the Distributor receives a
monthly distribution fee from each Fund at an annual rate of 0.25% of the
average daily net assets of the Fund's Investor Class and Class A shares, which
is an expense of the Investor Class and Class A shares of the respective Funds
for distribution or service activities as designated by the Distributor.
Pursuant to the Class C Plan, each Fund pays the Distributor a monthly
distribution fee, which is an expense of the Class C shares of the Fund, at an
annual rate of 0.75% of the average daily net assets of the respective Fund's
Class C shares, along with a shareholder service fee at an annual rate of 0.25%
of the average daily net assets of the Class C shares of the Fund for a total
12b-1 fee of 1.00%. Class I shares are not subject to a distribution or service
fee.

The Plans provide that the distribution and service fees are payable to the
Distributor regardless of the amounts actually expended by the Distributor for
distribution of the Fund's shares and service activities.

(C) SALES CHARGES.  The Fund was advised by the Distributor that the amount of
sales charges retained on sales of Investor Class and Class A shares were $482
and $1,465, respectively, for the four-month period ended April 30, 2010.

(D) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT.  NYLIM
Service Company LLC, an affiliate of New York Life Investments, is the Fund's
transfer, dividend disbursing and shareholder servicing agent pursuant to an
agreement between NYLIM Service Company LLC and the Trust. NYLIM Service Company
LLC has entered into an agreement with Boston Financial Data Services, Inc.
("BFDS") pursuant to which BFDS performs certain transfer agent services on
behalf of NYLIM Service Company LLC. Transfer agent expenses incurred by the
Fund for the four-month period ended April 30, 2010, were as follows:

<Table>

cost of providing transfer agency services. In an effort to reduce total
transfer agency expenses, the Fund has implemented a small account fee on
certain types of accounts. Certain shareholders with an account balance of less
than $1,000 are charged an annual per account fee of $20 (assessed semi-
annually). These fees are included in transfer agent fees shown on the Statement
of Operations.

At a special meeting held on October 30, 2009, the shareholders of the Epoch
International Small Cap Fund approved the reorganization of the Epoch
International Small Cap Fund with and into MainStay Epoch International Small
Cap Fund. Effective after the close of business on November 13, 2009, the Class

NOTE 11--NEW ACCOUNTING PRONOUNCEMENT:

In January 2010, the Financial Accounting Standards Board ("FASB") issued
Accounting Standards Update ("ASU") No. 2010-06 "Improving Disclosures about
Fair Value Measurements". ASU 2010-06 requires reporting entities to make new
disclosures about amount and reasons for significant transfers in and out of
Level 1 and Level 2 fair value measurements and input and valuation techniques
used to measure fair value for both recurring and nonrecurring fair value
measurements that fall in either Level 2 or Level 3, and information on
purchases, sales, issuances, and settlements in the roll forward of activity in
Level 3 fair value measures. The new and revised disclosure requirements are
effective for interim and annual reporting periods beginning after December 15,
2009 except for the disclosures about purchases, sales, issuances, and
settlements in the roll forward of activity in Level 3 fair value measures,
which are effective for fiscal years beginning after December 15, 2010. As of
April 30, 2010, the Fund has adopted ASU 2010-06. The adoption of ASU 2010-06
has not impacted the amounts reported in the financial statements; however,
there are additional disclosures in the Portfolio of Investments.

In connection with the preparation of the financial statements of the Fund as of
and for the fiscal four-month period ended April 30, 2010, events and
transactions subsequent to April 30, 2010 through the date the financial
statements were issued have been evaluated by the Fund's management for possible
adjustment and/or disclosure. No subsequent events requiring financial statement
adjustment or disclosure have been identified.

NOTE 13--DIVIDENDS:

On May 17, 2010, the Fund's management declared dividends and distributions in
the amount of the Fund's remaining undistributed Investment Company Taxable
Income and Net Capital Gain, if any, for the Fund's taxable year ended December
31, 2009, which is in accordance with the provisions of Section 855(a) of the
Internal Revenue Code. The declaration date was May 17, 2010; it is expected
that ex-dividend, reinvestment, and payable date, will be in December 2010.

        MESSAGE FROM THE PRESIDENT AND SEMIANNUAL REPORT

        Unaudited - April 30, 2010



MESSAGE FROM THE PRESIDENT

During the six months ended April 30, 2010, stock and bond markets generally
advanced, despite some volatility in January and February. Domestic small-cap
stocks were particularly strong, and U.S. stocks at all capitalization levels
provided double digit returns. Value stocks outpaced growth stocks for companies
of all sizes during the reporting period.

International stocks provided positive returns overall, but results varied
widely by country. Concerns about Greece's ability to meet its debt obligations
led many investors to abandon their holdings in Greece and question their
investments in several peripheral European nations where perceived risk had
increased. For the six-month reporting period, equities in the Far East
(including Japan) tended to be stronger than those in Europe.

The economic recovery in the United States continued. Real gross domestic
product advanced in the first quarter of 2010, though at a slower pace than in
the fourth quarter of 2009. The Federal Open Market Committee kept the targeted
federal funds rate at a historically low level throughout the reporting period,
which prompted many investors to leave the safety of U.S. Treasury securities in
search of higher yield.

In the high-yield bond market, lower-rated credits tended to be the strongest
performers. With investment-grade investors crossing into high-yield territory,
however, the highest-rated high-yield credits also saw strong demand. In the
municipal market, new-issue supply was reduced by government incentives that
encouraged municipal issuers to raise funds in the taxable market. In the
leveraged-loan market, new issuance strengthened, but extensive repayments
caused the market as a whole to contract.


Throughout the six-month reporting period, MainStay's portfolio managers sought
to make the most of market conditions within the investment strategies and risk
parameters of their respective Funds. While individual markets and Fund results
may vary, our pursuit of competitive returns over full market cycles has never
changed.

The information that follows provides a closer look
at the securities, strategies and market conditions that affected your MainStay
Fund(s) during the six months ended April 30, 2010. Of course, past performance
is no guarantee of future results. Even in a rising market, we believe that
maintaining a long-term perspective can be valuable. At MainStay, we believe
that in all markets, broad diversification, gradual allocation adjustments and
regular portfolio reviews can help guide you toward your long-range financial
goals.

We thank you for choosing MainStay Funds, and we look forward to serving your
investment needs for many years to come.

Sincerely,

/s/ STEPHEN P. FISHER


Stephen P. Fisher
President

1. Performance tables and graphs do not reflect the deduction of taxes that a
   shareholder would pay on distributions or Fund-share redemptions. Total
   returns reflect maximum applicable sales charges explained in this paragraph,
   change in share price, and reinvestment of dividend and capital gain
   distributions. The graphs assume an initial investment of $25,000 for Class A
   shares and $10,000 for all other classes and reflect the deduction of all
   sales charges that would have applied for the period of investment. Class A
   shares generally have a $25,000 minimum initial investment with no minimum
   subsequent purchase amount. For investors that, in the aggregate, have assets
   of $100,000 or more invested in any share classes of any of the MainStay
   Funds, the minimum initial investment is $15,000. Investor Class shares and
   Class A shares are sold with a maximum initial sales charge of 5.50% and an
   annual 12b-1 fee of 0.25%. Class B shares are sold with no initial sales
   charge, are subject to a contingent deferred sales charge ("CDSC") of up to
   5.00% if redeemed within the first six years of purchase, and have an annual
   12b-1 fee of 1.00%. Class C shares are sold with no initial sales charge, are
   subject to a CDSC of 1.00% if redeemed within one year of purchase, and have
   an annual 12b-1 fee of 1.00%. Class I shares are sold with no initial sales
   charge or CDSC, have no annual 12b-1 fee, and are generally available to
   corporate and institutional investors or individual investors with a minimum
   initial investment of $5 million. Performance figures reflect certain fee
   waivers and/or expense limitations, without which total returns may have been
   lower. For information on current fee waivers and/or expense limitations,
   please refer to the notes to the financial statements.

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY EPOCH U.S. ALL CAP FUND
(UNAUDITED)
- --------------------------------------------------------------------------------

The example below is intended to describe the fees and expenses borne by
shareholders during the six-month period from November 1, 2009, to April 30,
2010, and the impact of those costs on your investment.

EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, exchange fees, and sales charges (loads) on
purchases (as applicable), and (2) ongoing costs, including management fees,
distribution and/or service (12b-1) fees, and other Fund expenses (as
applicable). This example is intended to help you understand your ongoing costs
(in dollars) of investing in the Fund and to compare these costs with the
ongoing costs of investing in other mutual funds. The example is based on an
investment of $1,000 made at the beginning of the six-month period and held for
the entire period from November 1, 2009, to April 30, 2010.

This example illustrates your Fund's ongoing costs in two ways:

- - ACTUAL EXPENSES
The second and third data columns in the table below provide information about
actual account values and actual expenses. You may use the information in these
columns, together with the amount you invested, to estimate the expenses that
you paid during the six-months ended April 30, 2010. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number under the heading entitled "Expenses Paid
During Period" to estimate the expenses you paid on your account during this
period.

- - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The fourth and fifth data columns in the table below provide information about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense ratio and an assumed rate of return of 5% per year before expenses,
which is not the Fund's actual return. The hypothetical account values and
expenses may not be used to estimate the actual ending account balances or
expenses you paid for the six-month period shown. You may use this information
to compare the ongoing costs of investing in the Fund with the ongoing costs of
investing in other Funds. To do so, compare this 5% hypothetical example with
the 5% hypothetical examples that appear in the shareholder reports of the other
Funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as
redemption fees, if applicable, exchange fees, or sales charges (loads).
Therefore, the fourth and fifth data columns of the table are useful in
comparing ongoing costs only and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.

   and 0.95% for Class I) multiplied by the average account value over the
   period, divided by 365 and multiplied by 181 (to reflect the one-half year
   period). The table above represents the actual expenses incurred during the
   one-half year period.

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

QUESTIONS ANSWERED BY PORTFOLIO MANAGERS DAVID PEARL, WILLIAM PRIEST, CFA, AND
MICHAEL WELHOELTER, CFA, OF EPOCH INVESTMENT PARTNERS, INC. (EPOCH), THE FUND'S
SUBADVISOR.

HOW DID MAINSTAY EPOCH U.S. ALL CAP FUND PERFORM RELATIVE TO ITS PEERS AND ITS
BENCHMARK DURING THE SIX MONTHS ENDED APRIL 30, 2010?

Excluding all sales charges, MainStay Epoch U.S. All Cap Fund returned 16.93%
for Investor Class shares, 17.19% for Class A shares, 16.51% for Class B shares
and 16.49% for Class C shares for the six months ended April 30, 2010. Over the
same period, the Fund's Class I shares returned 17.30%. All share classes
outperformed the 16.13% return of the average Lipper(1) multi-cap core fund for
the same period. All share classes underperformed the 17.64% return of the
Russell 3000(R) Index(2) for the six months ended April 30, 2010. Investor
Class, Class A, Class B and Class I shares outperformed--and Class C shares
underperformed--the 16.50% return of the Russell 3000(R) Growth Index(3) for the
same period. The Russell 3000(R) Index is the Fund's broad-based securities-
market index. See pages 5 and 6 for Fund returns with sales charges.

WHAT MAJOR FACTORS INFLUENCED THE FUND'S RELATIVE PERFORMANCE DURING THE
REPORTING PERIOD?

Throughout the reporting period, we stayed true to our philosophy and process.
The Fund focused on quality companies that were producing free cash flow and
were run by strong management teams who allocated that cash flow to increase
shareholder returns. While the Fund generated robust absolute gains,
conservative stock selection (or, in other words, not buying highly leveraged,
highly cyclical or commodity-oriented companies) detracted from performance
relative to the Russell 3000(R) Index. These effects were partially offset by
effective sector allocation, which contributed positively to the Fund's relative
results.

DURING THE REPORTING PERIOD, WHICH SECTORS MADE THE STRONGEST CONTRIBUTIONS TO
THE FUND'S RELATIVE PERFORMANCE AND WHICH SECTORS MADE THE WEAKEST
CONTRIBUTIONS?

Relative to the Russell 3000(R) Index, the strongest-contributing sectors to the
Fund's performance were consumer staples, utilities and financials. Strong stock
selection across all three sectors helped relative performance, as did the
Fund's significant underweight position in consumer staples and modestly
overweight position in financials. While an underweight position in utilities
detracted somewhat from the Fund's returns, we shifted to a neutral weighting
relative to the benchmark by the end of the reporting period.

During the reporting period, the sectors that detracted the most from the Fund's
performance relative to the Russell 3000(R) Index were consumer discretionary
and materials. While the Fund benefited from overweight positions in both
sectors, the Fund's conservative stock selections detracted. The Fund's small
cash position also detracted, since the Fund was not fully invested in equities
during the significant market rally.

WHICH INDIVIDUAL STOCKS WERE THE STRONGEST CONTRIBUTORS TO THE FUND'S ABSOLUTE
PERFORMANCE DURING THE REPORTING PERIOD AND WHICH STOCKS DETRACTED?

On an absolute basis, insurance company MetLife, aerospace & defense company
Boeing and electronic payments company Visa made the strongest contributions to
the Fund's results. MetLife advanced as market forces boosted the company's
variable annuity, 401(k) and asset management operations. Boeing benefited from
prospects of a large replacement cycle in the commercial aerospace industry and
positive reactions to the company's new aircraft. Visa produces an immense
amount of free cash flow and has benefited from the continued move from cash to
credit and debit cards. Visa has also seen its stock price rise with the
economic rebound.

Global reinsurance company Everest Re Group, wire-transfer provider Western
Union and oil, gas & consumable fuels company ExxonMobil were among the greatest
detractors from the Fund's absolute performance. Everest Re suffered losses as a
result of the earthquake in Chile. We exited the Fund's position in Western
Union when the company failed to execute on the business plan the way we thought
they should. ExxonMobil underperformed with the rest of the energy sector, but
we maintained the Fund's position in the stock.

DID THE FUND MAKE ANY SIGNIFICANT PURCHASES OR SALES DURING THE REPORTING
PERIOD?

Among the stocks that the Fund purchased during the reporting period were
semiconductor manufacturer Texas Instruments, brokerage services provider TD
Ameritrade, Internet software & services company Yahoo! and pharmaceuticals
company Abbott Laboratories.

We believed that Texas Instruments would continue to grow market share in the
analog market because of solid innovation and a scale advantage in sales
productivity. The company had also been gaining in its share of distributors. We
expected TD Ameritrade to benefit from increased activity in the capital markets
and from increased savings rates by consumers, particularly if the company
continued to gain market share from other discount brokers. We found the search-
advertising partnership between Yahoo! and Microsoft appealing, and we felt that
Yahoo! could benefit from a rebound in display advertising and from the movement
toward online advertising. Abbott Laboratories had experienced strong revenue
growth across its many business divisions, and we believe its management has a
track record of being a good allocator of capital.

In addition to the sale of Western Union, we sold the Fund's positions in
medical device maker Boston Scientific and weapon and space systems company
Alliant Techsystems during the reporting period. Although Boston Scientific's
acquisition of Guidant initially showed promise, the two stent makers took
longer than anticipated to provide synergies. We exited the Fund's position in
Boston Scientific to redeploy the assets in more promising opportunities,
specifically Abbott Laboratories, which in addition to providing the Fund
exposure to the stent business, provided a better product portfolio. Alliant
Techsystems suffered when the U.S. administration took aim at a number of NASA's
programs, leaving Alliant Techsystems' future somewhat uncertain. We sold the
Fund's position in the stock.

HOW DID THE FUND'S WEIGHTINGS CHANGE DURING THE REPORTING PERIOD?

During the reporting period, the Fund's weightings in the consumer discretionary
and energy sectors modestly increased in absolute terms and relative to the
Russell 3000(R) Index. In the consumer discretionary sector, we increased the
Fund's position in GameStop, which we felt would benefit from the beginning
stages of a new gaming cycle. We also added Tupperware Brands to the Fund. In
energy, we added several new companies, with a focus on oil services. We
modestly reduced the Fund's exposure to utilities, primarily through the sale of
Indiana-based energy holding company Vectren.

HOW WAS THE FUND POSITIONED AT THE END OF APRIL 2010?

As of April 30, 2010, the Fund's most substantially overweight sectors relative
to the Russell 3000(R) Index were consumer discretionary, information technology
and materials. As of the same date, the Fund's most substantially underweight
sector relative to the Russell 3000(R) Index was consumer staples. The Fund had
no direct exposure to the telecommunications services sector as of April 30,
2010.

20    MainStay Epoch U.S. All Cap Fund     The notes to the financial statements
are an integral part of, and should be read in conjunction with, the financial
statements.



NOTES TO FINANCIAL STATEMENTS UNAUDITED

NOTE 1--ORGANIZATION AND BUSINESS:

MainStay Funds Trust (the "Trust") is organized as a Delaware Statutory Trust
and is governed by a Declaration of Trust dated April 8, 2009. The Trust is
registered under the Investment Company Act of 1940, as amended (the "1940
Act"), as an open-end management investment company, and is comprised of twenty-
nine funds (collectively referred to as the "Funds"). These financial statements
and notes relate only to the MainStay Epoch U.S. All Cap Fund (the "Fund"), a
diversified fund. The Fund is the successor of the MainStay Epoch U.S. All Cap
Fund, a series of Eclipse Funds Inc. (the "Predecessor Fund"). The
reorganization of the Predecessor Fund with and into the Fund, which was not
subject to shareholder approval under applicable law, occurred on February 26,
2010. All information regarding and references to periods prior to the
commencement of operations of the Fund relate to the Predecessor Fund.

The Fund currently offers five classes of shares. Class I shares commenced
operations on January 2, 1991. Class A shares, Class B shares and Class C shares
commenced operations on January 2, 2004. Investor Class shares commenced
operations on February 28, 2008. Investor Class and Class A shares are offered
at net asset value ("NAV") per share plus an initial sales charge. No sales
charge applies on investments of $1 million or more (and certain other qualified
purchases) in Investor Class and Class A shares, but a contingent deferred sales
charge is imposed on certain redemptions of such shares within one year of the
date of purchase. Class B shares and Class C shares are offered at NAV without
an initial sales charge, although a declining contingent deferred sales charge
may be imposed on redemptions made within six years of purchase of Class B
shares and a 1.00% contingent deferred sales charge may be imposed on
redemptions made within one year of purchase of Class C shares. Class I shares
are offered at NAV and are not subject to a sales charge. Depending upon
eligibility, Class B shares convert to either Investor Class or Class A shares
eight years after the date they were purchased. Additionally, depending upon
eligibility, Investor Class shares may convert to Class A shares and Class A
shares may convert to Investor Class shares. The five classes of shares have the
same voting (except for issues that relate solely to one class), dividend,
liquidation and other rights, and the same terms and conditions, except that
Class B and Class C shares are subject to higher distribution and/or service fee
rates than Investor Class and Class A shares under a distribution plan pursuant
to Rule 12b-1 under the 1940 Act. Class I shares are not subject to a
distribution and/or service fee.

The Fund's investment objective is to seek long-term capital appreciation.

NOTE 2--SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with accounting
principles generally accepted in the United States of America ("GAAP") and
follows the significant accounting policies described below.

(A) SECURITIES VALUATION.  Equity securities are valued at the latest quoted
sales prices as of the close of regular trading on the New York Stock Exchange
("Exchange") (generally 4:00 p.m. Eastern time) on each day the Fund is open for
business ("valuation date"). Securities that are not traded on the valuation
date are valued at the mean of the latest quoted bid and asked prices. Prices
normally are taken from the principal market in which each security trades.
Options contracts are valued at the last posted settlement price on the market
where such options are principally traded. Investments in other mutual funds are
valued at their NAVs as of the close of the Exchange on the valuation date.

Temporary cash investments acquired over 60 days prior to maturity are valued
using the latest bid prices or using valuations based on a matrix system (which
considers such factors as security prices, yields, maturities, and ratings),
both as furnished by independent pricing services. Other temporary cash
investments which mature in 60 days or less ("short-term investments") are
valued at amortized cost. The amortized cost method involves valuing a security
at its cost on the date of purchase and thereafter assuming a constant
amortization to maturity of the difference between the principal amount due at
maturity and cost.

Securities for which market quotations are not readily available are valued by
methods deemed in good faith by the Fund's Board to represent fair value. Equity
and non-equity securities which may be valued in this manner include, but are
not limited to: (i) a security the trading for which has been halted or
suspended; (ii) a debt security that has recently gone into default and for
which there is not a current market quotation; (iii) a security of an issuer
that has entered into a restructuring; (iv) a security that has been de-listed
from a national exchange; (v) a security the market price of which is not
available from an independent pricing source or, if so provided, does not, in
the opinion of the Fund's Manager or Subadvisor, as defined in Note 3(A),
reflect the security's market value; and (vi) a security where the trading on
that security's principal market is temporarily closed at a time when, under
normal conditions, it would be open. At April 30, 2010, the Fund did not hold
securities that were valued in such a manner.

"Fair value" is defined as the price that the Fund would receive upon selling an
investment in an orderly transaction to an independent buyer in the principal or
most advantageous market of the investment. Fair value measurements are
determined within a framework that has established a three-tier hierarchy which
maximizes the use of observable market data and minimizes the use of
unobservable inputs to establish classification of fair value measurements for
disclosure purposes. "Inputs" refer broadly to the assumptions that market
participants would use in pricing the asset or liability, including assumptions
about risk, such as the

                                                   mainstayinvestments.com    21



NOTES TO FINANCIAL STATEMENTS UNAUDITED (CONTINUED)



risk inherent in a particular valuation technique used to measure fair value
using a pricing model and/or the risk inherent in the inputs for the valuation
technique. Inputs may be observable or unobservable. Observable inputs are
inputs that reflect the assumptions market participants would use in pricing the
asset or liability based on market data obtained from sources independent of the
reporting entity. Unobservable inputs are inputs that reflect the reporting
entity's own assumptions about the assumptions market participants would use in
pricing the asset or liability developed based on the information available in
the circumstances. The inputs or methodology used for valuing securities may not
be an indication of the risks associated with investing in those securities. The
three-tier hierarchy of inputs is summarized in the three broad Levels listed
below.

- - Level 1--quoted prices in active markets for identical investments

- - Level 2--other significant observable inputs (including quoted prices for
  similar investments in active markets, interest rates and yield curves,
  prepayment speeds, credit risks, etc.)

- - Level 3--significant unobservable inputs (including the Fund's own assumptions
  about the assumptions that market participants would use in determining the
  fair value of investments)

The aggregate value by input level, as of April 30, 2010, for the Fund's
investments is included at the end of the Fund's Portfolio of Investments.

The valuation techniques used by the Fund to measure fair value during the six-
month period ended April 30, 2010 maximized the use of observable inputs and
minimized the use of unobservable inputs. The Fund may have utilized some of the
following fair value techniques: multi-dimensional relational pricing models,
option adjusted spread pricing and estimating the price that would have
prevailed in a liquid market for an international equity security given
information available at the time of evaluation, when there are significant
events after the close of local foreign markets. For the six-month period ended
April 30, 2010, there have been no changes to the fair value methodologies.

(B) FEDERAL INCOME TAXES.   The Fund's policy is to comply with the requirements
of the Internal Revenue Code of 1986, as amended (the "Internal Revenue Code")
applicable to regulated investment companies and to distribute all of the
taxable income to the shareholders of the Fund within the allowable time limits.
Therefore, no federal income tax provision is required.

Management evaluates its tax positions to determine if the tax positions taken
meet the minimum recognition threshold in connection with accounting for
uncertainties in income tax positions taken or expected to be taken for the
purposes of measuring and recognizing tax liabilities in the financial
statements. Recognition of tax benefits of an uncertain tax position is required
only when the position is "more likely than not" to be sustained assuming
examination by taxing authorities. Management has analyzed the Fund's tax
positions taken on federal income tax returns for all open tax years (current
and prior three tax years), and has concluded that no provision for federal
income tax is required in the Fund's financial statements. The Fund's federal
and state income and federal excise tax returns for tax years for which the
applicable statutes of limitations have not expired are subject to examination
by the Internal Revenue Service and state departments of revenue.

(C) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS.  Dividends and distributions
are recorded on the ex-dividend date. The Fund intends to declare and pay
dividends of net investment income and distributions of net realized capital and
currency gains, if any, annually. Unless the shareholder elects otherwise, all
dividends and distributions are reinvested in the same class of shares of the
Fund, at NAV. Dividends and distributions to shareholders are determined in
accordance with federal income tax regulations and may differ from GAAP.

(D) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  The Fund records security
transactions on the trade date. Realized gains and losses on security
transactions are determined using the identified cost method. Dividend income is
recognized on the ex-dividend date and interest income is accrued as earned
using the effective interest rate method. Discounts and premiums on securities
purchased, other than short-term investments, for the Fund are accreted and
amortized, respectively, on the effective interest rate method over the life of
the respective securities or, in the case of a callable security, over the
period to the first date of call. Discounts and premiums on short-term
investments are accreted and amortized, respectively, on the straight-line
method.

Investment income and realized and unrealized gains and losses on investments of
the Fund are allocated to separate classes of shares pro rata based upon their
relative net assets on the date the income is earned or realized and unrealized
gains and losses are incurred.

(E) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred, except where direct allocations of expenses can be made. Expenses
(other than transfer agent expenses and fees incurred under the shareholder
services plans and the distribution plans further discussed in Note 3(B)) are
allocated to separate classes of shares pro rata based upon their relative NAV
on the date the expenses are incurred. The expenses borne by the Fund, including
those of related parties to the Fund, are shown in the Statement of Operations.


22    MainStay Epoch U.S. All Cap Fund



(F) USE OF ESTIMATES.  In preparing financial statements in conformity with
GAAP, management makes estimates and assumptions that affect the reported
amounts and disclosures in the financial statements. Actual results could differ
from those estimates.

(G) REPURCHASE AGREEMENTS.  The Fund may enter into repurchase agreements to
earn income. The Fund may enter into repurchase agreements only with financial
institutions that are deemed by the Manager or Subadvisor to be creditworthy,
pursuant to guidelines established by the Fund's Board. Repurchase agreements
are considered under the 1940 Act to be collateralized loans by a Fund to the
seller secured by the securities transferred to the Fund.

When the Fund invests in repurchase agreements, the Fund's custodian takes
possession of the collateral pledged for investments in such repurchase
agreements. The underlying collateral is valued daily on a mark-to-market basis
to determine that the value, including accrued interest, exceeds the repurchase
price. In the event of the seller's default of the obligation to repurchase, the
Fund has the right to liquidate the collateral and apply the proceeds in
satisfaction of the obligation. Under certain circumstances, in the event of
default or bankruptcy by the other party to the agreement, realization and/or
retention of the collateral may be subject to legal proceedings and possible
realized loss to the Fund.

(H) SECURITIES LENDING.  In order to realize additional income, the Fund may
engage in securities lending, subject to the limitations set forth in the 1940
Act, and relevant guidance by the staff of the Securities and Exchange
Commission. In the event the Fund does engage in securities lending, the Fund
will lend through its custodian, State Street Bank and Trust Company ("State
Street"). State Street will manage the Fund's cash collateral in accordance with
the Lending Agreement between the Fund and State Street, and indemnify the
Fund's portfolio against counterparty risk. The loans will be collateralized by
cash or securities at least equal at all times to the market value of the
securities loaned. Collateral will consist of U.S. Government securities, cash
equivalents or irrevocable letters of credit. The Fund may bear the risk of
delay in recovery of, or loss of rights in, the securities loaned should the
borrower of the securities experience financial difficulty. The Fund may also
record realized gain or loss on securities deemed sold due to a borrower's
inability to return securities on loan. The Fund will receive compensation for
lending its securities in the form of fees or retain a portion of interest on
the investment of any cash received as collateral. The Fund also will continue
to receive interest and dividends on the securities loaned and any gain or loss
in the market price of the securities loaned that may occur during the term of
the loan will be for the account of the Fund.

Although the Fund and New York Life Investments (as defined in Note 3(A)) have
temporarily suspended securities lending, the Fund and New York Life Investments
reserve the right to reinstitute lending when deemed appropriate. The Fund had
no portfolio securities on loan as of April 30, 2010.

(I) INDEMNIFICATIONS.  Under the Trust's organizational documents, its officers
and trustees are indemnified against certain liabilities that may arise out of
performance of their duties to the Trust. Additionally, in the normal course of
business, the Fund enters into contracts with third-party service providers that
contain a variety of representations and warranties and which provide general
indemnifications. The Fund's maximum exposure under these arrangements is
unknown, as this would involve future claims that may be made against the Fund
that have not yet occurred. Based on experience, management is of the view that
the risk of loss in connection with these potential indemnification obligations
is remote. However, there can be no assurance that material liabilities related
to such obligations will not arise in the future, which could adversely impact
the Fund.

NOTE 3--FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER AND SUBADVISOR.  New York Life Investment Management LLC ("New York
Life Investments" or "Manager"), a registered investment adviser and an
indirect, wholly-owned subsidiary of New York Life Insurance Company ("New York
Life"), serves as the Fund's Manager, pursuant to a Management Agreement, as
amended ("Management Agreement"). The Manager provides offices, conducts
clerical, recordkeeping and bookkeeping services, and keeps most of the
financial and accounting records required to be maintained by the Fund. Except
for the portion of salaries and expenses that are the responsibility of the
Fund, the Manager also pays the salaries and expenses of all personnel
affiliated with the Fund and the operational expenses of the Fund. Epoch
Investment Partners, Inc. (the "Subadvisor"), a registered investment adviser,
is responsible for the day-to-day portfolio management of the Fund. Pursuant to
the terms of a Subadvisory Agreement between New York Life Investments and the
Subadvisor, New York Life Investments pays for the services of the Subadvisor.

The Fund pays the Manager a monthly fee for services performed and facilities
furnished at an annual rate of the Fund's average daily net assets as follows:
0.85% on assets up to $500 million, 0.825% on assets from $500 million to $1
billion and 0.80% on assets in excess of $1 billion. The effective management
fee rate was 0.85% for the six-month period ended April 30, 2010.

Effective February 26, 2010, New York Life Investments has entered into a
written expense limitation agreement, under which it agreed to waive a portion
of the management fee or reimburse expenses of the appropriate class of the Fund
to the extent necessary to ensure that the total ordinary

                                                   mainstayinvestments.com    23



NOTES TO FINANCIAL STATEMENTS UNAUDITED (CONTINUED)



operating expenses (total ordinary operating expenses excludes taxes, interest,
litigation, extraordinary expenses, brokerage, other transaction expenses
relating to the purchase or sale of portfolio investments, and the fees and
expenses of any other funds in which the Fund invests) of a class do not exceed
the following percentages of average daily net assets: Investor Class, 1.85%;
Class B, 2.60%; Class C, 2.60% and Class I, 1.00%. This expense limitation
agreement expires February 28, 2011 and is reviewed annually by the Board in
connection with its review of the Fund's investment advisory agreements. Based
on its review, the Board may agree to maintain, modify or terminate the
agreement.

For the period August 1, 2009 to February 25, 2010, New York Life Investments
had agreed to voluntarily waive or reimburse the expenses of the appropriate
class of the Fund so that the total ordinary operating expenses of a class did
not exceed the following percentages of average daily net assets: Investor
Class, 1.85%; Class B, 2.60%; Class C, 2.60% and Class I, 1.00%.

For the six-month period ended April 30, 2010, New York Life Investments earned
fees from the Fund in the amount of $1,449,849.

State Street, 1 Lincoln Street, Boston, Massachusetts 02111, provides sub-
administration and sub-accounting services to the Fund pursuant to an agreement
with New York Life Investments. These services include calculating the daily
NAVs of the Fund, maintaining the general ledger and sub-ledger accounts for the
calculation of the Fund's respective NAVs, and assisting New York Life
Investments in conducting various aspects of the Fund's administrative
operations. For providing these services to the Fund, State Street is
compensated by New York Life Investments.

(B) DISTRIBUTION AND SERVICE FEES.  The Trust, on behalf of the Fund, has
entered into a Distribution Agreement with NYLIFE Distributors LLC (the
"Distributor"), an indirect, wholly-owned subsidiary of New York Life. The Fund
has adopted distribution plans, (the "Plans") in accordance with the provisions
of Rule 12b-1 under the 1940 Act.

Pursuant to the Investor Class and Class A Plans, the Distributor receives a
monthly distribution fee from the Investor Class and Class A shares at an annual
rate of 0.25% of the average daily net assets of the Investor Class and Class A
shares for distribution or service activities as designated by the Distributor.
Pursuant to the Class B and Class C Plans, Class B and Class C shares of the
Fund pay the Distributor a monthly distribution fee at an annual rate of 0.75%
of the average daily net assets of the Fund's Class B and Class C shares, along
with a service fee at an annual rate of 0.25% of the average daily net assets of
the Class B and Class C shares of the Fund for a total 12b-1 fee of 1.00%. Class
I shares are not subject to a distribution or service fee.

The Plans provide that the distribution and service fees are payable to the
Distributor regardless of the amounts actually expended by the Distributor for
distribution of the Fund's shares and service activities.

(C) SALES CHARGES.  The Fund was advised by the Distributor that the amount of
sales charges retained on sales of Investor Class and Class A shares were $2,888
and $1,497, respectively, for the six-month period ended April 30, 2010. The
Fund was also advised that the Distributor retained contingent deferred sales
charges on redemptions of Class B and Class C shares of $7,264 and $13,
respectively, for the six-month period ended April 30, 2010.

(D) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT.  NYLIM
Service Company LLC, an affiliate of New York Life Investments, is the Fund's
transfer, dividend disbursing and shareholder servicing agent pursuant to an
agreement between NYLIM Service Company LLC and the Trust. NYLIM Service Company
LLC has entered into an agreement with Boston Financial Data Services, Inc.
("BFDS") pursuant to which BFDS performs certain transfer agent services on
behalf of NYLIM Service Company LLC. Transfer agent expenses incurred by the
Fund for the six-month period ended April 30, 2010, were as follows:

<Table>

(E) SMALL ACCOUNT FEE.  Shareholders with small accounts adversely impact the
cost of providing transfer agency services. In an effort to reduce total
transfer agency expenses, the Fund has implemented a small account fee on
certain types of accounts. Certain shareholders with an account balance of less
than $1,000 are charged an annual per account fee of $20 (assessed semi-
annually). These fees are included in transfer agent fees shown on the Statement
of Operations.

(F) CAPITAL.  At April 30, 2010, New York Life and its affiliates beneficially
held shares of the Fund with the following values and percentages of net assets
as follows:

NOTE 5--CUSTODIAN:

State Street is the custodian of the cash and the securities of the Fund.
Custodial fees are charged to the Fund based on the market value of securities
in the Fund and the number of certain cash transactions incurred by the Fund.

NOTE 6--LINE OF CREDIT:

The Fund and certain affiliated funds maintain a line of credit with a syndicate
of banks in order to secure a source of funds for temporary purposes to meet
unanticipated or excessive shareholder redemption requests.

The line of credit is in the amount of $125,000,000 and the commitment fee rate
is an annual rate of 0.10% of the average commitment amount, plus a 0.04% up-
front payment payable, regardless of usage, to The Bank of New York Mellon,
which serves as agent to the syndicate. The commitment fee and upfront payment
are allocated among certain MainStay Funds based upon net assets and other
factors. Interest on any revolving credit loan is charged based upon the Federal
Funds Advances rate or the one month LIBOR rate, whichever is higher. There were
no borrowings made or outstanding with respect to the Fund on the line of credit
during the six-month period ended April 30, 2010.

NOTE 7--PURCHASES AND SALES OF SECURITIES (IN 000'S):

During the six-month period ended April 30, 2010, purchases and sales of
securities, other than short-term securities, were $195,820 and $76,530,
respectively.

(a) In addition to any automatic conversion features described above in Note 1
    with respect to Investor Class, Class A and B shares, you generally may also
    elect to convert your shares on a voluntary basis into another share class
    of the same fund for which you are eligible. However, the following
    limitations apply:

    - Investor Class and Class A shares that remain subject to a CDSC are
      ineligible for a voluntary conversion; and

    - All Class B and C shares are ineligible for a voluntary conversion.

These limitations do not impact any automatic conversion features described in
Note 1 with respect to Investor Class, Class A and B shares.

An investor or an investor's financial intermediary may contact the Fund to
request a voluntary conversion between shares classes of the same Fund. You may
be required to provide sufficient information to establish eligibility to
convert to the new share class. All permissible conversions will be made on the
basis of the relevant NAVs of the two classes without the imposition of any
sales load, fee or other charge. If you fail to remain eligible for the new
share class, you may automatically be converted back to your original share
class, or into another share class, if appropriate.

NOTE 9--NEW ACCOUNTING PRONOUNCEMENT:

In January 2010, the Financial Accounting Standards Board ("FASB") issued
Accounting Standards Update ("ASU") No. 2010-06 "Improving Disclosures about
Fair Value Measurements". ASU 2010-06 requires reporting entities to make new
disclosures about amount and reasons for significant transfers in and out of
Level 1 and Level 2 fair value measurements and input and valuation techniques
used to measure fair value for both recurring and nonrecurring fair value
measurements that fall in either Level 2 or Level 3, and information on
purchased, sales, issuances, and settlements in the roll forward of activity in
Level 3 fair value measures. The new and revised disclosure requirements are
effective for interim and annual reporting periods beginning after December 15,
2009 except for the disclosures about purchased, sales, issuances, and
settlements in the roll forward of activity in Level 3 fair value measures,
which are effective for fiscal years beginning after December 15, 2010. As of
April 30, 2010, the Fund has adopted ASU 2010-06. The adoption of ASU 2010-06
has not impacted the amounts reported in the financial statements; however,
there are additional disclosures in the Portfolio of Investments.

NOTE 10--SUBSEQUENT EVENTS:

In connection with the preparation of the financial statements of the Fund as of
and for the fiscal six-month period ended April 30, 2010, events and
transactions subsequent to April 30, 2010 through the date the financial
statements were issued have been evaluated by the Fund's management for possible
adjustment and/or disclosure. No subsequent events requiring financial statement
adjustment or disclosure have been identified.

        MESSAGE FROM THE PRESIDENT AND SEMIANNUAL REPORT

        Unaudited - April 30, 2010



MESSAGE FROM THE PRESIDENT

During the six months ended April 30, 2010, stock and bond markets generally
advanced, despite some volatility in January and February. Domestic small-cap
stocks were particularly strong, and U.S. stocks at all capitalization levels
provided double digit returns. Value stocks outpaced growth stocks for companies
of all sizes during this period.

International stocks provided positive returns overall, but results varied
widely by country. Concerns about Greece's ability to meet its debt obligations
led many investors to abandon their holdings in Greece and question their
investments in several peripheral European nations where perceived risk had
increased. For the six months ended April 30, 2010, equities in the Far East
(including Japan) tended to be stronger than those in Europe.

The economic recovery in the United States continued. Real gross domestic
product advanced in the first quarter of 2010, though at a slower pace than in
the fourth quarter of 2009. The Federal Open Market Committee kept the targeted
federal funds rate at a historically low level throughout the six-month period,
which prompted many investors to leave the safety of U.S. Treasury securities in
search of higher yield.

In the high-yield bond market, lower-rated credits tended to be the strongest
performers. With investment-grade investors crossing into high-yield territory,
however, the highest-rated high-yield credits also saw strong demand. In the
municipal market, new-issue supply was reduced by government incentives that
encouraged municipal issuers to raise funds in the taxable market. In the
leveraged-loan market, new issuance strengthened, but extensive repayments
caused the market as a whole to contract.


During the period covered by this report, MainStay's portfolio managers sought
to make the most of market conditions within the investment strategies and risk
parameters of their respective Funds. While individual markets and Fund results
may vary, our pursuit of competitive returns over full market cycles has never
changed.

The information that follows provides a closer look
at the securities, strategies and market conditions that affected your MainStay
Fund(s) during the period covered by this report. Of course, past performance is
no guarantee of future results. Even in a rising market, we believe that
maintaining a long-term perspective can be valuable. At MainStay, we believe
that in all markets, broad diversification, gradual allocation adjustments and
regular portfolio reviews can help guide you toward your long-range financial
goals.

We thank you for choosing MainStay Funds, and we look forward to serving your
investment needs for many years to come.

Sincerely,

/s/ STEPHEN P. FISHER

Stephen P. Fisher
President

   a shareholder would pay on distribution or Fund-share redemptions. Total
   returns reflect maximum applicable sales charges explained in this paragraph,
   change in share price, and reinvestment of dividend and capital gain
   distributions. The graphs assume an initial investment of $25,000 for Class A
   shares and $10,000 for all other classes and reflect the deduction of all
   sales charges that would have applied for the period of investment. Class A
   shares generally have a $25,000 minimum initial investment with no minimum
   subsequent purchase amount. For investors that, in the aggregate, have assets
   of $100,000 or more invested in any share classes of any of the MainStay
   Funds, the minimum initial investment is $15,000. Investor Class and Class A
   shares are sold with a maximum initial sales charge of 5.5% and an annual
   12b-1 fee of 0.25%. Class C shares are sold with no initial sales charge and
   are subject to a contingent deferred sales charge ("CDSC") of 1.00%. Class I
   shares are sold with no initial sales charge or CDSC, have no annual 12b-1
   fee, and are generally available to corporate and institutional investors or
   individual investors with a minimum initial investment of $5 million.

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY EPOCH U.S. EQUITY FUND
(UNAUDITED)
- --------------------------------------------------------------------------------

The example below is intended to describe the fees and expenses borne by
shareholders during the six-month period from November 1, 2009, to April 30,
2010, and the impact of those costs on your investment.

EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, exchange fees, and sales charges (loads) on
purchases (as applicable), and (2) ongoing costs, including management fees,
distribution and/or service (12b-1) fees, and other Fund expenses (as
applicable). This example is intended to help you understand your ongoing costs
(in dollars) of investing in the Fund and to compare these costs with the
ongoing costs of investing in other mutual funds. The example is based on an
investment of $1,000 made at the beginning of the six-month period and held for
the entire period from November 1, 2009, to April 30, 2010.

This example illustrates your Fund's ongoing costs in two ways:

- - ACTUAL EXPENSES
The second and third data columns in the table below provide information about
actual account values and actual expenses. You may use the information in these
columns, together with the amount you invested, to estimate the expenses that
you paid during the six-months ended April 30, 2010. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number under the heading entitled "Expenses Paid
During Period" to estimate the expenses you paid on your account during this
period.

- - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The fourth and fifth data columns in the table below provide information about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense ratio and an assumed rate of return of 5% per year before expenses,
which is not the Fund's actual return. The hypothetical account values and
expenses may not be used to estimate the actual ending account balances or
expenses you paid for the six-month period shown. You may use this information
to compare the ongoing costs of investing in the Fund with the ongoing costs of
investing in other Funds. To do so, compare this 5% hypothetical example with
the 5% hypothetical examples that appear in the shareholder reports of the other
Funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as
redemption fees, if applicable, exchange fees, or sales charges (loads).
Therefore, the fourth and fifth data columns of the table are useful in
comparing ongoing costs only and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.

1. Expenses are equal to the Fund's annualized expense ratio of each class
   (1.22% for Investor Class, 1.34% for Class A, 1.97% for Class C and 1.09% for
   Class I) multiplied by the average account value over the period, divided by
   365 and multiplied by 181 days for Class A and Class I (to reflect the one-
   half year period) and 168 days for Investor Class and Class C (to reflect the
   since-inception period). The table above represents actual expenses incurred
   during the one-half year period.

2. Expenses paid during the period reflect ongoing costs for the period from
   inception through April 30, 2010. Had these shares been offered for the full
   six-month period ended April 30, 2010, and had the Fund provided a
   hypothetical 5% annualized return, expenses paid during the period would have
   been $6.11 for Investor Class and $9.84 for Class C and the ending account
   value would have been $1,018.70 for Investor Class and $1,015.00 for Class C.

3. Investor Class and Class C shares began investment operations on November 16,
   2009.

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS(1)

QUESTIONS ANSWERED BY PORTFOLIO MANAGERS DAVID PEARL, WILLIAM PRIEST, CFA, AND
MICHAEL WELHOELTER, CFA, OF EPOCH INVESTMENT PARTNERS, INC. (EPOCH), THE FUND'S
SUBADVISOR.

HOW DID MAINSTAY EPOCH U.S. EQUITY FUND PERFORM RELATIVE TO ITS PEERS AND ITS
BENCHMARK FOR THE FOUR MONTHS ENDED APRIL 30, 2010?

Excluding all sales charges, MainStay Epoch U.S. Equity Fund returned 6.55% for
Investor Class shares, 6.47% for Class A shares and 6.24% for Class C shares for
the four months ended April 30, 2010. Over the same period, the Fund's Class I
shares returned 6.54%. All share classes outperformed the 6.18% return of the
average Lipper(2) large-cap core fund. All share classes underperformed the
7.65% return of the Russell 1000(R) Index(3) and the 8.23% return of the Russell
3000(R) Index(4) for the same period. The Russell 1000(R) Index is the Fund's
broad-based securities-market index. See page 5 for Fund returns with sales
charges.

WHAT MAJOR FACTORS INFLUENCED THE FUND'S RELATIVE PERFORMANCE DURING THE
REPORTING PERIOD?

Throughout the reporting period, we stayed true to our philosophy and process.
The Fund focused on quality companies that produced free cash flow and that were
run by strong management teams who allocated that cash flow to increase
shareholder returns. While the Fund generated absolute gains, its conservative
stock selection detracted from performance relative to the Russell 1000(R) Index
in a market led by momentum stocks and stocks with higher volatility than the
market as a whole.

DURING THE REPORTING PERIOD, WHICH SECTORS MADE THE STRONGEST CONTRIBUTIONS TO
THE FUND'S RELATIVE PERFORMANCE AND WHICH SECTORS MADE THE WEAKEST
CONTRIBUTIONS?

Relative to the Russell 1000(R) Index, the strongest-contributing sectors to the
Fund's performance were telecommunication services, consumer staples and health
care. Strong stock selection across all three sectors helped relative
performance, as did the Fund's significantly underweight position in consumer
staples and more modestly underweight positions in telecommunication services
and health care.

During the reporting period, the sectors that detracted the most from the Fund's
performance relative to the Russell 1000(R) Index were energy and industrials.
Stock selection in each sector was weak and was only partially offset by sector
positioning. The Fund's position in cash also detracted, as the Fund was not
100% invested in equities during the significant market rally.

WHICH INDIVIDUAL STOCKS WERE THE STRONGEST CONTRIBUTORS TO THE FUND'S ABSOLUTE
PERFORMANCE DURING THE REPORTING PERIOD AND WHICH STOCKS DETRACTED?

On an absolute basis, aerospace & defense company Boeing and insurance companies
Prudential Financial and MetLife made the strongest contributions to the Fund's
performance. Boeing benefited from prospects of a large replacement cycle in the
commercial aerospace industry and from positive reactions to the company's new
aircraft. Prudential Financial gained market share and benefited from structural
improvements in fixed-income markets and a rebound in the equity markets, which
in turn benefited the company's variable annuity, 401(k) and asset management
operations. MetLife advanced for similar reasons.

Wire transfer service provider Western Union, weapon and space systems company
Alliant Techsystems and global reinsurance company Everest Re Group were among
the most significant detractors from the Fund's absolute performance. We exited
the Fund's position in Western Union when the stock disappointed. We also sold
Alliant Techsystems when the U.S. administration took aim at a number of NASA's
programs, leaving the future of Alliant Techsystems uncertain. Although Everest
Re Group suffered losses because of the Chilean earthquake, we continued to hold
the Fund's position in the company.

DID THE FUND MAKE ANY SIGNIFICANT PURCHASES OR SALES DURING THE REPORTING
PERIOD?

Among the stocks that the Fund purchased during the reporting period were
semiconductor manufacturer Texas Instruments, brokerage service provider TD
Ameritrade, Internet software & services company Yahoo! and pharmaceuticals
company Abbott Laboratories.

We believed that Texas Instruments would continue to gain market share in the
analog market because of solid innovation and a scale advantage in sales
productivity. The company had also been gaining in its share of distributors. We
expected TD Ameritrade to benefit from increased activity in the capital markets
and increased savings rates by consumers, particularly if the company continued
to gain market share from other discount brokers. We found the search-
advertising partnership between Yahoo! and Microsoft appealing, and we felt that
Yahoo! could benefit from a

rebound in display advertising and from the movement toward online advertising.
Abbott Laboratories had experienced strong revenue growth across its many
business divisions, and we believe its management has a track record of being a
good allocator of capital.

In addition to the sales of Western Union and Alliant Techsystems, we sold the
Fund's positions in medical device manufacturer Boston Scientific, natural gas
distributor ONEOK and retail food-and-drug chain Safeway during the reporting
period. Although Boston Scientifics' acquisition of Guidant at first showed
promise, the two stent makers took longer than anticipated to provide synergies,
so we sold the stock and redeployed the proceeds in health care companies such
as Abbott Laboratories that had better risk/reward characteristics. In light of
the supply/demand balance for natural gas and other opportunities available, we
decided to exit the Fund's position in ONEOK. The Fund's position in Safeway was
based on the premise that the company would perform well in a weak domestic
economy experiencing notable food inflation. When food inflation and the
potential to pass through increased costs slowed in the recent downturn, we sold
the position.

HOW DID THE FUND'S WEIGHTINGS CHANGE DURING THE REPORTING PERIOD?

During the reporting period, there were no significant changes in sector
weightings. We modestly reduced the Fund's exposure to utilities, primarily
through the sale of ONEOK. We modestly increased the Fund's allocation to
telecommunication services, primarily through a new position in Qwest
Communications International, which provides data, Internet, video and voice
services in the U.S. and internationally.

HOW WAS THE FUND POSITIONED AT THE END OF APRIL 2010?

As of April 30, 2010, the Fund's most substantially overweight sectors relative
to the Russell 1000(R) Index were information technology and financials. On the
same date, the Fund's most substantially underweight sectors relative to the
Russell 1000(R) Index were consumer discretionary and consumer staples.

16    MainStay Epoch U.S. Equity Fund  The notes to the financial statements are
an integral part of, and should be read in conjunction with, the financial
statements.



NOTES TO FINANCIAL STATEMENTS UNAUDITED

NOTE 1--ORGANIZATION AND BUSINESS:

MainStay Funds Trust (the "Trust") is organized as a Delaware Statutory Trust
and is governed by a Declaration of Trust dated April 8, 2009. The Trust is
registered under the Investment Company Act of 1940, as amended (the "1940
Act"), as an open-end management investment company, and is comprised of twenty-
nine funds (collectively referred to as the "Funds"). These financial statements
and notes relate only to the MainStay Epoch U.S. Equity Fund (the "Fund"), a
diversified Fund. The Fund is the successor to the Epoch U.S. Large Cap Equity
Fund (the "Predecessor Fund"), which was a series of a different registered
investment company for which Epoch Investment Partners, Inc. served as
investment adviser.

The Fund currently offers four classes of shares: Investor Class, Class A, Class
C and Class I shares. Investor Class and Class C shares were seeded as of the
close of business on November 13, 2009 and were first offered and commenced
operations on November 16, 2009. Class I and Class A shares commenced operations
(under former designations), on December 3, 2008 and February 3, 2009,
respectively. Effective January 4, 2010, the Fund changed its fiscal year end
and tax year end from December 31 to October 31. Investor Class and Class A
shares are offered at net asset value ("NAV") per share plus an initial sales
charge. No sales charge applies on investments of $1 million or more (and
certain other qualified purchases) in Investor Class and Class A shares, but a
contingent deferred sales charge is imposed on certain redemptions of such
shares within one year of the date of purchase. Class C shares are offered at
NAV without an initial sales charge, although a 1.00% contingent deferred sales
charge may be imposed on redemptions made within one year of purchase of Class C
shares. Class I shares are offered at NAV and are not subject to a sales charge.
Depending upon eligibility, Investor Class shares may convert to Class A shares
and Class A shares may convert to Investor Class shares. The four classes of
shares have the same voting (except for issues that relate solely to one class),
dividend, liquidation and other rights, and the same terms and conditions,
except that Class C shares are subject to higher distribution and/or service fee
rates than Investor Class and Class A shares under a distribution plan pursuant
to Rule 12b-1 under the 1940 Act. Class I shares are not subject to a
distribution and/or service fee.

The Fund's investment objective is to seek long-term capital appreciation.

The financial statements of the Fund reflect the historical results of the
Institutional Class and P shares of the Predecessor Fund prior to its
reorganization. (See Note 9.) Upon the completion of the reorganization, the
Class I and Class A shares of the Fund assumed the performance, financial and
other information of the Institutional Class and Class P shares, respectively.
All information regarding and references to periods prior to the commencement of
operations of the Fund refer to the Predecessor Fund.

NOTE 2--SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with accounting
principles generally accepted in the United States of America ("GAAP") and
follows the significant accounting policies described below.

(A) SECURITIES VALUATION.  Equity securities are valued at the latest quoted
sales prices as of the close of regular trading on the New York Exchange
("Exchange") (generally 4:00 p.m. Eastern time) on each day the Fund is open for
business ("valuation date"). Securities that are not traded on the valuation
date are valued at the mean of the latest quoted bid and asked prices. Prices
normally are taken from the principal market in which each security trades.
Investments in other mutual funds are valued at their NAVs as of the close of
the Exchange on the valuation date.

Temporary cash investments acquired over 60 days prior to maturity are valued
using the latest bid prices or using valuations based on a matrix system (which
considers such factors as security prices, yields, maturities, and ratings),
both as furnished by independent pricing services. Other temporary cash
investments which mature in 60 days or less ("short-term investments") are
valued at amortized cost. The amortized cost method involves valuing a security
at its cost on the date of purchase and thereafter assuming a constant
amortization to maturity of the difference between the principal amount due at
maturity and cost.

Certain events may occur between the time that foreign markets close, on which
securities held by the Fund principally trade, and the time at which the Fund's
NAV is calculated. These events may include, but are not limited to, situations
relating to a single issuer in a market sector, significant fluctuations in U.S.
or foreign markets, natural disasters, armed conflicts, governmental actions or
other developments not tied directly to the securities markets. Should the
Manager or Subadvisor, as defined in Note 3(A), conclude that such events may
have affected the accuracy of the last price reported on the local foreign
market, the Manager or Subadvisor may, pursuant to procedures adopted by the
Fund's Board, adjust the value of the local price to reflect the impact on the
price of such securities as a result of such events. Additionally, international
equity securities are also fair valued whenever the movement of a particular
index exceeds certain thresholds. In such cases, the securities are fair valued
by applying factors provided by a third party vendor in accordance with the
Fund's policies and procedures. At April 30, 2010, certain foreign equity
securities held by the Fund were fair valued.

Securities for which market quotations are not readily available are valued by
methods deemed in good faith by the Fund's Board to represent fair value. Equity
and non-equity securities which may be valued in this manner include, but are
not limited to: (i) a security the trading for

                                                   mainstayinvestments.com    17



NOTES TO FINANCIAL STATEMENTS UNAUDITED (CONTINUED)


which has been halted or suspended; (ii) a debt security that has recently gone
into default and for which there is not a current market quotation; (iii) a
security of an issuer that has entered into a restructuring; (iv) a security
that has been de-listed from a national exchange; (v) a security the market
price of which is not available from an independent pricing source or, if so
provided, does not, in the opinion of the Fund's Manager or Subadvisor, as
defined in Note 3(A), reflect the security's market value; and (vi) a security
where the trading on that security's principal market is temporarily closed at a
time when, under normal conditions, it would be open. At April 30, 2010, the
Fund did not hold securities that were valued in such a manner.

"Fair value" is defined as the price that the Fund would receive upon selling an
investment in an orderly transaction to an independent buyer in the principal or
most advantageous market of the investment. Fair value measurements are
determined within a framework that has established a three-tier hierarchy which
maximizes the use of observable market data and minimizes the use of
unobservable inputs to establish classification of fair value measurements for
disclosure purposes. "Inputs" refer broadly to the assumptions that market
participants would use in pricing the asset or liability, including assumptions
about risk, such as the risk inherent in a particular valuation technique used
to measure fair value using a pricing model and/or the risk inherent in the
inputs for the valuation technique. Inputs may be observable or unobservable.
Observable inputs are inputs that reflect the assumptions market participants
would use in pricing the asset or liability based on market data obtained from
sources independent of the reporting entity. Unobservable inputs are inputs that
reflect the reporting entity's own assumptions about the assumptions market
participants would use in pricing the asset or liability developed based on the
information available in the circumstances. The inputs or methodology used for
valuing securities may not be an indication of the risks associated with
investing in those securities. The three-tier hierarchy of inputs is summarized
in the three broad Levels listed below.

- - Level 1--quoted prices in active markets for identical investments

- - Level 2--other significant observable inputs (including quoted prices for
  similar investments in active markets, interest rates and yield curves,
  prepayment speeds, credit risks, etc.)

- - Level 3--significant unobservable inputs (including the Fund's own assumptions
  about the assumptions that market participants would use in determining the
  fair value of investments)

The aggregate value by input level, as of April 30, 2010, for the Fund's
investments is included at the end of the Fund's Portfolio of Investments.

The valuation techniques used by the Fund to measure fair value during the four-
month period ended April 30, 2010 maximized the use of observable inputs and
minimized the use of unobservable inputs. The Fund may have utilized some of the
following fair value techniques: multi-dimensional relational pricing models,
option adjusted spread pricing and estimating the price that would have
prevailed in a liquid market for an international equity security given
information available at the time of evaluation, when there are significant
events after the close of local foreign markets. For the four-month period ended
April 30, 2010, there have been no changes to the fair value methodologies.

(B) FEDERAL INCOME TAXES.   The Fund's policy is to comply with the requirements
of the Internal Revenue Code of 1986, as amended (the "Internal Revenue Code")
applicable to regulated investment companies and to distribute all of the
taxable income to the shareholders of the Fund within the allowable time limits.
Therefore, no federal income tax provision is required.

Investment income received by the Fund from foreign sources may be subject to
foreign income taxes. These foreign income taxes are generally withheld at the
source.

Management evaluates its tax positions to determine if the tax positions taken
meet the minimum recognition threshold in connection with accounting for
uncertainties in income tax positions taken or expected to be taken for the
purposes of measuring and recognizing tax liabilities in the financial
statements. Recognition of tax benefits of an uncertain tax position is required
only when the position is "more likely than not" to be sustained assuming
examination by taxing authorities. Management has analyzed the Fund's tax
positions taken on federal income tax returns for all open tax years (current
and prior three tax years), and has concluded that no provision for federal
income tax is required in the Fund's financial statements. The Fund's federal
and state income and federal excise tax returns for tax years for which the
applicable statutes of limitations have not expired are subject to examination
by the Internal Revenue Service and state departments of revenue.

(C) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS.  Dividends and distributions
are recorded on the ex-dividend date. The Fund intends to declare and pay
dividends of net investment income and distributions of net realized capital and
currency gains, if any, annually. Unless the shareholder elects otherwise, all
dividends and distributions are reinvested in the same class of shares of the
Fund, at NAV. Dividends and distributions to shareholders are determined in
accordance with federal income tax regulations and may differ from GAAP.

(D) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  The Fund records security
transactions on the trade date. Realized gains and losses on security
transactions are determined using the identified cost method. Dividend income is
recognized on the ex-dividend date

18    MainStay Epoch U.S. Equity Fund



and interest income is accrued as earned using the effective interest rate
method. Discounts and premiums on short-term investments are accreted and
amortized, respectively, on the straight-line method.

Investment income and realized and unrealized gains and losses on investments of
the Fund are allocated to separate classes of shares pro rata based upon their
relative net assets on the date the income is earned or realized and unrealized
gains and losses are incurred.

(E) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred, except where direct allocations of expenses can be made. Expenses
(other than transfer agent expenses and fees incurred under the shareholder
services plans and the distribution plans further discussed in Note 3(B)) are
allocated to separate classes of shares pro rata based upon their relative NAV
on the date the expenses are incurred. The expenses borne by the Fund, including
those of related parties to the Fund, are shown in the Statement of Operations.

(F) USE OF ESTIMATES.  In preparing financial statements in conformity with
GAAP, management makes estimates and assumptions that affect the reported
amounts and disclosures in the financial statements. Actual results could differ
from those estimates.

(G) REPURCHASE AGREEMENTS.  The Fund may enter into repurchase agreements to
earn income. The Fund may enter into repurchase agreements only with financial
institutions that are deemed by the Manager or Subadvisor to be creditworthy,
pursuant to guidelines established by the Fund's Board. Repurchase agreements
are considered under the 1940 Act to be collateralized loans by a Fund to the
seller secured by the securities transferred to the Fund.

When the Fund invests in repurchase agreements, the Fund's custodian takes
possession of the collateral pledged for investments in such repurchase
agreements. The underlying collateral is valued daily on a mark-to-market basis
to determine that the value, including accrued interest, exceeds the repurchase
price. In the event of the seller's default of the obligation to repurchase, the
Fund has the right to liquidate the collateral and apply the proceeds in
satisfaction of the obligation. Under certain circumstances, in the event of
default or bankruptcy by the other party to the agreement, realization and/or
retention of the collateral may be subject to legal proceedings and possible
realized loss to the Fund.

(H) SECURITIES LENDING.  In order to realize additional income, the Fund may
engage in securities lending, subject to the limitations set forth in the 1940
Act, and relevant guidance by the staff of the Securities and Exchange
Commission. In the event the Fund does engage in securities lending, the Fund
will lend through its custodian, State Street Bank and Trust Company ("State
Street"). State Street will manage the Fund's cash collateral in accordance with
the Lending Agreement between the Fund and State Street, and indemnify the
Fund's portfolio against counterparty risk. The loans will be collateralized by
cash or securities at least equal at all times to the market value of the
securities loaned. Collateral will consist of U.S. Government securities, cash
equivalents or irrevocable letters of credit. The Fund may bear the risk of
delay in recovery of, or loss of rights in, the securities loaned should the
borrower of the securities experience financial difficulty. The Fund may also
record realized gain or loss on securities deemed sold due to a borrower's
inability to return securities on loan. The Fund will receive compensation for
lending its securities in the form of fees or retain a portion of interest on
the investment of any cash received as collateral. The Fund also will continue
to receive interest and dividends on the securities loaned and any gain or loss
in the market price of the securities loaned that may occur during the term of
the loan will be for the account of the Fund.

Although the Fund and New York Life Investments (as defined in Note 3(A)) have
temporarily suspended securities lending, the Fund and New York Life Investments
reserve the right to reinstitute lending when deemed appropriate. The Fund had
no portfolio securities on loan as of April 30, 2010.

(I) INDEMNIFICATIONS.  Under the Trust's organizational documents, its officers
and trustees are indemnified against certain liabilities that may arise out of
performance of their duties to the Trust. Additionally, in the normal course of
business, the Fund enters into contracts with third-party service providers that
contain a variety of representations and warranties and which provide general
indemnifications. The Fund's maximum exposure under these arrangements is
unknown, as this would involve future claims that may be made against the Fund
that have not yet occurred. Based on experience, management is of the view that
the risk of loss in connection with these potential indemnification obligations
is remote. However, there can be no assurance that material liabilities related
to such obligations will not arise in the future, which could adversely impact
the Fund.

NOTE 3--FEES AND RELATED PARTY TRANSACTIONS

(A) MANAGER AND SUBADVISOR.  New York Life Investment Management LLC ("New York
Life Investments" or "Manager"), a registered investment adviser and an
indirect, wholly-owned subsidiary of New York Life Insurance Company ("New York
Life"), serves as the Fund's Manager, pursuant to a Management Agreement, as
amended ("Management Agreement"). The Manager provides offices, conducts
clerical, recordkeeping and bookkeeping services, and keeps most of the
financial and accounting records required to be maintained by the Fund. Except
for the portion of salaries and expenses that are the

                                                   mainstayinvestments.com    19



NOTES TO FINANCIAL STATEMENTS UNAUDITED (CONTINUED)


responsibility of the Fund, the Manager also pays the salaries and expenses of
all personnel affiliated with the Fund and the operational expenses of the Fund.
Epoch Investment Partners, Inc. ("Epoch" or "Subadvisor"), a registered
investment adviser, serves as Subadvisor to the Fund and is responsible for the
day-to-day portfolio management of the Fund. Pursuant to the terms of an
Subadvisory Agreement between New York Life Investments and the Subadvisor, New
York Life Investments pays for the services of the Subadvisor.

The Fund pays the Manager a monthly fee for services performed and facilities
furnished at an annual rate of 0.80% of the Fund's average daily net assets.

Effective after the close of business on November 13, 2009, New York Life
Investments entered into a written expense limitation agreement under which it
has agreed to reimburse expenses of Class A and Class I shares of the Fund so
that the total ordinary operating expenses (total ordinary operating expenses
excludes taxes, interest, litigation, extraordinary expenses, brokerage and
other transaction expense relating to the purchase or sale of portfolio
investments and the fees and expenses of any other funds in which the Fund
invests) for Class A and Class I shares do not exceed the following percentages
of average daily net assets, Class A, 1.34% and Class I, 1.09%. These expense
limitations were based on the total annual operating expenses of the Predecessor
Fund (adjusted to reflect any applicable expense limitation agreement.) New York
Life Investments will apply an equivalent waiver or reimbursement, in an amount
equal to the number of basis points waived for Class A shares, to Investor Class
and Class C shares of the Fund. This agreement will be in effect for a two-year
period unless extended by New York Life Investments and approved by the Fund's
Board in connection with its review of the Fund's investment advisory agreement.
Based on its review, the Board may maintain, modify or terminate the agreement.

Prior to the close of business on November 13, 2009, Epoch had a written expense
limitation agreement under which it had agreed to waive a portion of the
Predecessor Fund's management fee or reimburse the expenses of the appropriate
class of the Predecessor Fund so that the class' total ordinary operating
expenses did not exceed the following percentages of average daily net assets
for each class: Class A, 1.34%; and Class I, 1.09%. The agreement did not apply
to interest, taxes, brokerage commissions, other expenditures capitalized in
accordance with generally accepted accounting principles or other extraordinary
expenses not incurred in the ordinary course of business. The total amount of
reimbursement recoverable by Epoch was the sum of all fees previously waived or
reimbursed by Epoch to the Predecessor Fund during any of the previous three (3)
years, less any reimbursement previously paid by the Predecessor Fund to Epoch
with respect to any waivers, reductions, and payments made.

For the four-month period ended April 30, 2010, New York Life Investments earned
fees from the Fund in the amount of $479,134 and waived its fees in the amount
of $44,535.

State Street, 1 Lincoln Street, Boston, Massachusetts 02111, provides sub-
administration and sub-accounting services to the Fund pursuant to an agreement
with New York Life Investments. These services include calculating the daily
NAVs of the Fund, maintaining the general ledger and sub-ledger accounts for the
calculation of the Fund's respective NAVs, and assisting New York Life
Investments in conducting various aspects of the Fund's administrative
operations. For providing these services to the Fund, State Street is
compensated by New York Life Investments.

(B) DISTRIBUTION AND SERVICE FEES.  Effective after the close of business on
November 13, 2009, the Trust, on behalf of the Fund, has entered into a
Distribution Agreement with NYLIFE Distributors LLC (the "Distributor"), an
indirect, wholly-owned subsidiary of New York Life. The Fund has adopted
distribution and service plans, (the "Plans") in accordance with the provisions
of Rule 12b-1 under the 1940 Act.

Pursuant to the Investor Class and Class A Plans, the Distributor receives a
monthly distribution fee from each Fund at an annual rate of 0.25% of the
average daily net assets of the Fund's Investor Class and Class A shares, which
is an expense of the Investor Class and Class A shares of the respective Funds
for distribution or service activities as designated by the Distributor.
Pursuant to the Class C Plan, each Fund pays the Distributor a monthly
distribution fee, which is an expense of the Class C shares of the Fund, at an
annual rate of 0.75% of the average daily net assets of the respective Fund's
Class C shares, along with a shareholder service fee at an annual rate of 0.25%
of the average daily net assets of the Class C shares of the Fund for a total
12b-1 fee of 1.00%. Class I shares are not subject to a distribution or service
fee.

The Plans provide that the distribution and service fees are payable to the
Distributor regardless of the amounts actually expended by the Distributor for
distribution of the Fund's shares and service activities.

(C) SALES CHARGES.  The Fund was advised by the Distributor that the amount of
sales charges retained on sales of Investor Class and Class A shares were $181
and $94, respectively, for the four-month period ended April 30, 2010.

(D) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT.  NYLIM
Service Company LLC, an affiliate of New York Life Investments, is the Fund's
transfer, dividend disbursing and shareholder servicing agent pursuant to an
agreement  between NYLIM Service Company LLC and the Trust. NYLIM Service
Company LLC has entered into an agreement with Boston Financial Data Services,
Inc. ("BFDS") pursuant to which BFDS performs certain transfer agent services on
behalf of

<Table>

- ----------------------------------------------

</Table>


(E) SMALL ACCOUNT FEE.  Shareholders with small accounts adversely impact the
cost of providing transfer agency services. In an effort to reduce total
transfer agency expenses, the Fund has implemented a small account fee on
certain types of accounts. Certain shareholders with an account balance of less
than $1,000 are charged an annual per account fee of $20 (assessed semi-
annually). These fees are included in transfer agent fees shown on the Statement
of Operations.

(F) CAPITAL.  At April 30, 2010, New York Life and its affiliates beneficially
held shares of the Fund with the following values and percentages of net assets
as follows:

<Table>

services provided to the Fund by the Office of the General Counsel of New York
Life Investments is payable directly by the Fund. For the four-month period
ended April 30, 2010, these fees, which are included in professional fees shown

- ------------------------------------------------

</Table>


NOTE 5--CUSTODIAN:

State Street is the custodian of the cash and the securities of the Fund.
Custodial fees are charged to the Fund based on the market value of securities
in the Fund and the number of certain cash transactions incurred by the Fund.

NOTE 6--LINE OF CREDIT:

The Fund and certain affiliated funds maintain a line of credit with a syndicate
of banks in order to secure a source of funds for temporary purposes to meet
unanticipated or excessive shareholder redemption requests.

The line of credit is in the amount of $125,000,000 and the commitment fee rate
is an annual rate of 0.10% of the average commitment amount, plus a 0.04% up-
front payment payable, regardless of usage, to The Bank of New York Mellon,
which serves as agent to the syndicate. The commitment fee and upfront payment
are allocated among certain MainStay Funds based upon net assets and other
factors. Interest on any revolving credit loan is charged based upon the Federal
Funds Advances rate or the one month LIBOR rate, whichever is higher. There were
no borrowings made or outstanding with respect to the Fund on the line of credit
during the four-month period ended April 30, 2010.

In January 2010, the Financial Accounting Standards Board ("FASB") issued
Accounting Standards Update ("ASU") No. 2010-06 "Improving Disclosures about
Fair Value Measurements". ASU 2010-06 requires reporting entities to make new
disclosures about amount and reasons for significant transfers in and out of
Level 1 and Level 2 fair value measurements and input and valuation techniques
used to measure fair value for both recurring and nonrecurring fair value
measurements that fall in either Level 2 or Level 3, and information on
purchases, sales, issuances, and settlements in the roll forward of activity in
Level 3 fair value measures. The new and revised disclosure requirements are
effective for interim and annual reporting periods beginning after December 15,
2009 except for the disclosures about purchases, sales, issuances, and
settlements in the roll forward of activity in Level 3 fair value measures,
which are effective for fiscal years beginning after December 15, 2010. As of
April 30, 2010, the Fund has adopted ASU 2010-06. The adoption of ASU 2010-06
has not impacted the amounts reported in the financial statements; however,
there are additional disclosures in the Portfolio of Investments.

In connection with the preparation of the financial statements of the Fund as of

transactions subsequent to April 30, 2010 through the date the financial
statements were issued have been evaluated by the Fund's management for possible
adjustment and/or disclosure. No subsequent events requiring financial statement
adjustment or disclosure have been identified.

NOTE 12--DIVIDENDS:

On May 17, 2010, the Fund's management declared dividends and distributions in
the amount of the Fund's remaining undistributed Investment Company Taxable
Income and Net Capital Gain, if any, for the Fund's taxable year ended December
31, 2009, which is in accordance with the provisions of Section 855(a) of the

that ex-dividend, reinvestment, and payable date will be in December 2010.

During the six months ended April 30, 2010, stock and bond markets generally
advanced, despite some volatility in January and February. Domestic small-cap
stocks were particularly strong, and U.S. stocks at all capitalization levels
provided double digit returns. Value stocks outpaced growth stocks for companies
of all sizes during the reporting period.



International stocks provided positive returns overall, but results varied
widely by country. Concerns about Greece's ability to meet its debt obligations
led many investors to abandon their holdings in Greece and question their
investments in several peripheral European nations where perceived risk had
increased. For the six-month reporting period, equities in the Far East
(including Japan) tended to be stronger than those in Europe.



The economic recovery in the United States continued. Real gross domestic
product advanced in the first quarter of 2010, though at a slower pace than in
the fourth quarter of 2009. The Federal Open Market Committee kept the targeted
federal funds rate at a historically low level throughout the reporting period,
which prompted many investors to leave the safety of U.S. Treasury securities in
search of higher yield.



In the high-yield bond market, lower-rated credits tended to be the strongest
performers. With investment-grade investors crossing into high-yield territory,
however, the highest-rated high-yield credits also saw strong demand. In the
municipal market, new-issue supply was reduced by government incentives that
encouraged municipal issuers to raise funds in the taxable market. In the
leveraged-loan market, new issuance strengthened, but extensive repayments
caused the market as a whole to contract.




Throughout the six-month reporting period, MainStay's portfolio managers sought
to make the most of market conditions within the investment strategies and risk
parameters of their respective Funds. While individual markets and Fund results
may vary, our pursuit of competitive returns over full market cycles has never
changed.



The information that follows provides a closer look
at the securities, strategies and market conditions that affected your MainStay
Fund(s) during the six months ended April 30, 2010. Of course, past performance
is no guarantee of future results. Even in a rising market, we believe that
maintaining a long-term perspective can be valuable. At MainStay, we believe
that in all markets, broad diversification, gradual allocation adjustments and
regular portfolio reviews can help guide you toward your long-range financial
goals.



We thank you for choosing MainStay Funds, and we look forward to serving your
investment needs for many years to come.



Sincerely,


/s/ STEPHEN P. FISHER


Stephen P. Fisher

1. Performance tables and graphs do not reflect the deduction of taxes that a
   shareholder would pay on distributions or Fund-share redemptions. Total
   returns reflect maximum applicable sales charges explained in this paragraph,
   change in share price, and reinvestment of dividend and capital gain
   distributions. The graphs assume an initial investment of $25,000 for Class A
   shares and $10,000 for all other classes and reflect the deduction of all
   sales charges that would have applied for the period of investment. Class A
   shares generally have a $25,000 minimum initial investment with no minimum
   subsequent purchase amount. For investors that, in the aggregate, have assets
   of $100,000 or more invested in any share classes of any of the MainStay
   Funds, the minimum initial investment is $15,000. Investor Class shares and
   Class A shares are sold with a maximum initial sales charge of 3.00% and an
   annual 12b-1 fee of 0.25%. Class B shares are sold with no initial sales
   charge, are subject to a contingent deferred sales charge ("CDSC") of up to
   3.00% if redeemed within the first four years of purchase, and have an annual
   12b-1 fee of 1.00%. Class C shares are sold with no initial sales charge, are
   subject to a CDSC of 1.00% if redeemed within one year of purchase, and have
   an annual 12b-1 fee of 1.00%. Class I shares are sold with no initial sales
   charge or CDSC, have no annual 12b-1 fee, and are generally available to
   corporate and institutional investors or individual investors with a minimum
   initial investment of $5 million. Performance figures reflect certain fee
   waivers and/or expense limitations, without which total returns may have been
   lower. For information on current fee waivers and/or expense limitations,

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY FLOATING RATE FUND
(UNAUDITED)

- --------------------------------------------------------------------------------


The example below is intended to describe the fees and expenses borne by
shareholders during the six-month period from November 1, 2009, to April 30,
2010, and the impact of those costs on your investment.



EXAMPLE



As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, exchange fees, and sales charges (loads) on
purchases (as applicable), and (2) ongoing costs, including management fees,
distribution and/or service (12b-1) fees, and other Fund expenses (as
applicable). This example is intended to help you understand your ongoing costs
(in dollars) of investing in the Fund and to compare these costs with the
ongoing costs of investing in other mutual funds. The example is based on an
investment of $1,000 made at the beginning of the six-month period and held for
the entire period from November 1, 2009, to April 30, 2010.



This example illustrates your Fund's ongoing costs in two ways:





- - ACTUAL EXPENSES


The second and third data columns in the table below provide information about
actual account values and actual expenses. You may use the information in these
columns, together with the amount you invested, to estimate the expenses that
you paid during the six-months ended April 30, 2010. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number under the heading entitled "Expenses Paid
During Period" to estimate the expenses you paid on your account during this
period.





- - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES


The fourth and fifth data columns in the table below provide information about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense ratio and an assumed rate of return of 5% per year before expenses,
which is not the Fund's actual return. The hypothetical account values and
expenses may not be used to estimate the actual ending account balances or
expenses you paid for the six-month period shown. You may use this information
to compare the ongoing costs of investing in the Fund with the ongoing costs of
investing in other Funds. To do so, compare this 5% hypothetical example with
the 5% hypothetical examples that appear in the shareholder reports of the other
Funds.



Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as
redemption fees, if applicable, exchange fees, or sales charges (loads).
Therefore, the fourth and fifth data columns of the table are useful in
comparing ongoing costs only and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.

8    MainStay Floating Rate Fund







PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS



QUESTIONS ANSWERED BY PORTFOLIO MANAGER ROBERT H. DIAL OF NEW YORK LIFE
INVESTMENTS,(1) THE FUND'S MANAGER.



HOW DID MAINSTAY FLOATING RATE FUND PERFORM RELATIVE TO ITS PEERS AND ITS
BENCHMARK DURING THE SIX MONTHS ENDED APRIL 30, 2010?



Excluding all sales charges, MainStay Floating Rate Fund returned 6.01% for
Investor Class shares, 6.06% for Class A shares, 5.73% for Class B shares and
5.61% for Class C shares during the six months ended April 30, 2010. Over the
same period, Class I shares returned 6.20%. All share classes underperformed the
7.88% return of the average Lipper(2) loan participation fund and the 8.83%
return of the Credit Suisse Leveraged Loan Index(3) for the six months ended
April 30, 2010. The Credit Suisse Leveraged Loan Index is the Fund's broad-based
securities-market index. See pages 5 and 6 for Fund returns with sales charges.



WHAT FACTORS ACCOUNTED FOR THE FUND'S RELATIVE PERFORMANCE DURING THE REPORTING
PERIOD?



The leveraged loan market followed its historic return in 2009 with a strong
beginning to 2010. The trend from the second half of 2009 continued, with the
advance led primarily by lower-rated, distressed and defaulted securities.



The reporting period was marked by a number of favorable developments, including
a shrinking default rate, repayment and extension activity and significant
growth in the new-issue market. On the default front, the trailing 12-month rate
fell to 5.8% in the first quarter of 2010, compared 9.6% at the end of 2009.
This is well below the all-time high of 10.8% in November 2009 and the lowest
default rate in the last year and a half.



Despite the increase in primary activity, new issue volume was overwhelmed by
repayments. As a result, the institutional loan market contracted 3% during the
first quarter of 2010. Because of the shrinking secondary market, as well as
strong demand from collateral-
ized loan obligations (CLOs) and relative value accounts, the market has become
increasingly issuer friendly.



The Fund's underweight position in riskier credits (unrated credits and those
rated CCC(4) and lower) detracted from relative performance as these loans
outperformed their higher-rated counterparts. In addition, a significant cash
position was a drag on the Fund's relative performance in light of the low
yields available from short-term money market instruments.



WHAT WERE SOME OF THE CHARACTERISTICS OF THE LOANS IN THE FUND DURING THE
REPORTING PERIOD?



The Fund invested in floating rate loans that had a weighted average effective
duration(5) of less than three months. The floating-rate loans may have final
maturities of seven to nine years, but underlying interest rate contracts
typically pegged to LIBOR(6) that reset every 30, 60, 90 or 180 days. The
weighted average reset figure for the Fund at the end of the six-month period
was 45 days. This means that, barring any defaults, if short-term interest rates
were to increase, we would expect the Fund to "catch up" within 45 days and
increase the yield it would pay to investors. If interest rates were to decline,
a decrease in yields would be anticipated.



HOW WAS THE FUND POSITIONED AT THE END OF THE REPORTING PERIOD?



As of April 30, 2010, the Fund was significantly underweight relative to the
Credit Suisse Leveraged Loan Index in loans that were either unrated or rated
CCC or lower. As of April 30, 2010, the Fund held 9.29% of its assets in loans
that were either unrated or rated CCC or lower, while 28.43% of the Credit
Suisse Leveraged Loan Index consisted of those riskier assets.

3. See footnote on page 6 for more information on the Credit Suisse Leveraged
   Loan Index.


4. Debt rated CCC by Standard & Poor's is deemed by Standard & Poor's to be
   currently vulnerable to nonpayment and is dependent upon favorable business,
   financial and economic conditions for the obligor. It is the opinion of
   Standard & Poor's that in the event of adverse business, financial or
   economic conditions, the obligor is not likely to have the capacity to meet
   its financial commitment on the obligation. When applied to Fund holdings,
   ratings are based solely on the creditworthiness of the bonds in the
   portfolio and are not meant to represent the security or safety of the Fund.


5. Duration is a measure of the price sensitivity of a fixed-income investment
   to changes in interest rates. Duration is expressed as a number of years and
   is considered a more accurate sensitivity-gauge than average maturity.


6. London interbank offered rates (LIBOR) are interest rates that are widely
   used as reference rates in bank, corporate and government lending agreements.

shareholder approval under applicable law, occurred on February 26, 2010. All
information regarding and references to periods prior to the commencement of
operations of the Fund relate to the Predecessor Fund.



The Fund currently offers five classes of shares. Class A shares, Class B
shares, Class C shares and Class I shares commenced operations on May 3, 2004.
Investor Class shares commenced operations on February 28, 2008. Investor Class
and Class A shares are offered at net asset value ("NAV") per share plus an
initial sales charge. No sales charge applies on investments of $500,000 or more
(and certain other qualified purchases) in Investor Class and Class A shares,
but a contingent deferred sales charge is imposed on certain redemptions of such
shares within one year of the date of purchase. Class B shares and Class C
shares are offered at NAV without an initial sales charge, although a declining
contingent deferred sales charge may be imposed on redemptions made within four
years of purchase of Class B shares and a 1.00% contingent deferred sales charge
may be imposed on redemptions made within one year of purchase of Class C
shares. Class I shares are offered at NAV and are not subject to a sales charge.
Depending upon eligibility, Class B shares convert to Investor Class or Class A
shares four years after the date they were purchased. Additionally, depending
upon eligibility, Investor Class shares may convert to Class A shares and Class
A shares may convert to Investor Class shares. The five classes of shares have
the same voting (except for issues that relate solely to one class), dividend,
liquidation and other rights, and the same terms and conditions, except that
Class B and Class C shares are subject to higher distribution and/or service fee
rates than Investor Class and Class A shares under a distribution plan pursuant
to Rule 12b-1 under the 1940 Act. Class I shares are not subject to a
distribution and/or service fee.



The Fund's investment objective is to seek to provide high current income.



NOTE 2--SIGNIFICANT ACCOUNTING POLICIES:



The Fund prepares its financial statements in accordance with accounting
principles generally accepted in the United States of America ("GAAP") and
follows the significant accounting policies described below.



(A) SECURITIES VALUATION.  Debt securities are valued at prices supplied by a
pricing agent or broker selected by the Fund's Manager (as defined in Note 3(A))
in consultation with the Fund's Subadvisor, if any (as defined in Note 3(A)),
whose prices reflect broker/dealer supplied valuations and electronic data
processing techniques, if such prices are deemed by the Fund's Manager, in
consultation with the Fund's Subadvisor, if any, to be representative of market
values, at the regular close of trading of the New York Stock Exchange
("Exchange") (generally 4:00 p.m. Eastern time) on each day the Fund is open for
business ("valuation date").



Loan assignments, participations and commitments are valued at the average of
bid quotations obtained from a pricing service. The Trust has engaged an
independent pricing service to provide market value quotations from dealers in
loans.



Temporary cash investments acquired over 60 days prior to maturity are valued
using the latest bid prices or using valuations based on a matrix system (which
considers such factors as security prices, yields, maturities, and ratings),
both as furnished by independent pricing services. Other temporary cash
investments which mature in 60 days or less ("short-term investments") are
valued at amortized cost. The amortized cost method involves valuing a security
at its cost on the date of purchase and thereafter assuming a constant
amortization to maturity of the difference between the principal amount due at
maturity and cost.



Securities for which market quotations are not readily available are valued by
methods deemed in good faith by the Fund's Board to represent fair value. Equity
and non-equity securities which may be valued in this manner include, but are
not limited to: (i) a security the trading for which has been halted or
suspended; (ii) a debt security that has recently gone into default and for
which there is not a current market quotation; (iii) a security of an issuer
that has entered into a restructuring; (iv) a security that has been de-listed
from a national exchange; (v) a security the market price of which is not
available from an independent pricing source or, if so provided, does not, in
the opinion of the Fund's Manager or Subadvisor, as defined in Note 3(A),
reflect the security's market value; and (vi) a security where the trading on
that security's principal market is temporarily closed at a time when, under
normal conditions, it would be open. At April 30, 2010, the Fund held securities
with a value of $1,470,302 that were valued in such a manner.



Certain events may occur between the time that foreign markets close, on which
securities held by the Fund principally trade, and the time at which the Fund's
NAV is calculated. These events may include, but are not limited to, situations
relating to a single issuer in a market sector,



                                                   mainstayinvestments.com    29







NOTES TO FINANCIAL STATEMENTS UNAUDITED (CONTINUED)





significant fluctuations in U.S. or foreign markets, natural disasters, armed
conflicts, governmental actions or other developments not tied directly to the
securities markets. Should the Manager, as defined in Note 3(A), conclude that
such events may have affected the accuracy of the last price reported on the
local foreign market, the Manager may, pursuant to procedures adopted by the
Fund's Board, adjust the value of the local price to reflect the impact on the
price of such securities as a result of such events. At April 30, 2010, certain
foreign equity securities held by the Fund were fair valued.



"Fair value" is defined as the price that the Fund would receive upon selling an
investment in an orderly transaction to an independent buyer in the principal or
most advantageous market of the investment. Fair value measurements are
determined within a framework that has established a three-tier hierarchy which
maximizes the use of observable market data and minimizes the use of
unobservable inputs to establish classification of fair value measurements for
disclosure purposes. "Inputs" refer broadly to the assumptions that market
participants would use in pricing the asset or liability, including assumptions
about risk, such as the risk inherent in a particular valuation technique used
to measure fair value using a pricing model and/or the risk inherent in the
inputs for the valuation technique. Inputs may be observable or unobservable.
Observable inputs are inputs that reflect the assumptions market participants
would use in pricing the asset or liability based on market data obtained from
sources independent of the reporting entity. Unobservable inputs are inputs that
reflect the reporting entity's own assumptions about the assumptions market
participants would use in pricing the asset or liability developed based on the
information available in the circumstances. The inputs or methodology used for
valuing securities may not be an indication of the risks associated with
investing in those securities. The three-tier hierarchy of inputs is summarized
in the three broad Levels listed below.



- - Level 1--quoted prices in active markets for identical investments



- - Level 2--other significant observable inputs (including quoted prices for
  similar investments in active markets, interest rates and yield curves,
  prepayment speeds, credit risks, etc.)



- - Level 3--significant unobservable inputs (including the Fund's own assumptions
  about the assumptions that market participants would use in determining the
  fair value of investments)



The aggregate value by input level, as of April 30, 2010, for the Fund's
investments is included at the end of the Fund's Portfolio of Investments.



The valuation techniques used by the Fund to measure fair value during the six-
month period ended April 30, 2010 maximized the use of observable inputs and
minimized the use of unobservable inputs. The Fund may have utilized some of the
following fair value techniques: multi-dimensional relational pricing models,
option adjusted spread pricing and estimating the price that would have
prevailed in a liquid market for an international equity security given
information available at the time of evaluation, when there are significant
events after the close of local foreign markets. For the six-month period ended
April 30, 2010, there have been no changes to the fair value methodologies.



Generally, a security is considered illiquid if it cannot be sold or disposed of
in the ordinary course of business at approximately the price at which it is
valued. Its illiquidity might prevent the sale of such security at a time when
the Manager or Subadvisor, if any, as defined in Note 3(A) might wish to sell,
and these securities could have the effect of decreasing the overall level of a
Fund's liquidity. Further, the lack of an established secondary market may make
it more difficult to value illiquid securities, requiring the Fund to rely on
judgments that may be somewhat subjective in determining value, which could vary
from the amount that the Fund could realize upon disposition. Difficulty in
selling illiquid securities may result in a loss or may be costly to the Fund.
Under the supervision of the Board, the Manager or Subadvisor, if any,
determines the liquidity of a Fund's investments; in doing so, the Manager or
Subadvisor, if any, may consider various factors, including (1) the frequency of
trades and quotations, (2) the number of dealers and prospective purchasers, (3)
the dealer undertakings to make a market, and (4) the nature of the security and
the market in which it trades (e.g., the time needed to dispose of the security,
the method of soliciting offers and the mechanics of transfer). Illiquid
securities generally will be valued in such manner, as the Board in good faith
deems appropriate to reflect their fair market value.



(B) FEDERAL INCOME TAXES.  The Fund's policy is to comply with the requirements
of the Internal Revenue Code of 1986, as amended (the "Internal Revenue Code")
applicable to regulated investment companies and to distribute all of the
taxable income to the shareholders of the Fund within the allowable time limits.
Therefore, no federal income tax provision is required.



Management evaluates its tax positions to determine if the tax positions taken
meet the minimum recognition threshold in connection with accounting for
uncertainties in income tax positions taken or expected to be taken for the
purposes of measuring and recognizing tax liabilities in the financial
statements. Recognition of tax benefits of an uncertain tax position is required
only when the position is "more likely than not" to be sustained assuming
examination by taxing authorities. Management has analyzed the Fund's tax
positions taken on federal income tax returns for all open tax years (current
and prior three tax years), and has concluded that no provision for federal
income tax is required in the Fund's financial statements. The Fund's


30    MainStay Floating Rate Fund







federal and state income and federal excise tax returns for tax years for which
the applicable statutes of limitations have not expired are subject to
examination by the Internal Revenue Service and state departments of revenue.



(C) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS.  Dividends and distributions
are recorded on the ex-dividend date. The Fund declares dividends of net
investment income daily and the Fund pays them monthly and declares and pays
distribution of net realized capital gains, if any, annually. Unless the
shareholder elects otherwise, all dividends and distributions are reinvested in
the same class of shares of the Fund, at NAV. Dividends and distributions to
shareholders are determined in accordance with federal income tax regulations
and may differ from GAAP.



(D) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  The Fund records security
transactions on the trade date. Realized gains and losses on security
transactions are determined using the identified cost method. Dividend income is
recognized on the ex-dividend date and interest income is accrued as earned
using the effective interest rate method. Discounts and premiums on short-term
investments are accreted and amortized, respectively, on the straight-line
method.



Investment income and realized and unrealized gains and losses on investments of
the Fund are allocated to separate classes of shares pro rata based upon their
relative net assets on the date the income is earned or realized and unrealized
gains and losses are incurred.



(E) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred, except where direct allocations of expenses can be made. Expenses
(other than transfer agent expenses and fees incurred under the shareholder
services plans and the distribution plans further discussed in Note 3(B)) are
allocated to separate classes of shares pro rata based upon their relative NAV
on the date the expenses are incurred. The expenses borne by the Fund, including
those of related parties to the Fund, are shown in the Statement of Operations.



(F) USE OF ESTIMATES.  In preparing financial statements in conformity with
GAAP, management makes estimates and assumptions that affect the reported
amounts and disclosures in the financial statements. Actual results could differ
from those estimates.



(G) REPURCHASE AGREEMENTS.  The Fund may enter into repurchase agreements to
earn income. The Fund may enter into repurchase agreements only with financial
institutions that are deemed by the Manager or Subadvisor to be creditworthy,
pursuant to guidelines established by the Fund's Board. Repurchase agreements
are considered under the 1940 Act to be collateralized loans by a Fund to the
seller secured by the securities transferred to the Fund.



When the Fund invests in repurchase agreements, the Fund's custodian takes
possession of the collateral pledged for investments in such repurchase
agreements. The underlying collateral is valued daily on a mark-to-market basis
to determine that the value, including accrued interest, exceeds the repurchase
price. In the event of the seller's default of the obligation to repurchase, the
Fund has the right to liquidate the collateral and apply the proceeds in
satisfaction of the obligation. Under certain circumstances, in the event of
default or bankruptcy by the other party to the agreement, realization and/or
retention of the collateral may be subject to legal proceedings and possible
realized loss to the Fund.



(H) LOAN ASSIGNMENTS, PARTICIPATIONS AND COMMITMENTS.  The Fund invests in loan
assignments and loan participations. Loan assignments and participations
("loans") are agreements to make money available (a "commitment") to a borrower
in a specified amount, at a specified rate and within a specified time. Such
loans are typically senior, secured and collateralized in nature. The Fund
records an investment when the borrower withdraws money and records interest as
earned. These loans pay interest at rates that are periodically reset by
reference to a base lending rate plus a spread. These base lending rates are
generally the prime rate offered by a designated U.S. bank or the London
InterBank Offered Rate ("LIBOR").



The loans in which the Fund invests are generally readily marketable, but may be
subject to some restrictions on resale. For example, the Fund may be
contractually obligated to receive approval from the agent bank and/or borrower
prior to the sale of these investments.



The Fund assumes the credit risk of the borrower, the selling participant and
any other persons interpositioned between the Fund and the borrower
("intermediate participants"). In the event that the borrower, selling
participant or intermediate participants become insolvent or enters into
bankruptcy, the Fund may incur certain costs and delays in realizing payment, or
may suffer a loss of principal and/or interest.



Unfunded commitments represent the remaining obligation of the Fund to the
borrower. At any point in time, up to the maturity date of the issue, the
borrower may demand the unfunded portion. These unfunded amounts are marked to
market and recorded in the Statement of Assets and Liabilities. (See Note 5.)



(I) REDEMPTION FEE.  Prior to April 1, 2010, the Fund imposed a 2.00% redemption
fee on redemptions (including exchanges) of Fund shares made within 60 days of
their date of purchase for any class. The redemption fee was designed to offset
brokerage commissions and other costs associated with short-term trading and was
not assessed on shares acquired through the reinvestment of dividends or
distributions paid by the Fund. The redemption fees are

NOTES TO FINANCIAL STATEMENTS UNAUDITED (CONTINUED)





included in the Statement of Changes in Net Assets' shares redeemed amount and
retained by the Fund.



(J) CONCENTRATION OF RISK.  The ability of issuers of debt securities held by
the Fund to meet their obligations may be affected by economic or political
developments in a specific country, industry or region.



The Fund invests in floating rate loans. The floating rate loans in which the
Fund principally invests are usually rated less than investment grade and are
generally considered speculative because they present a greater risk of loss,
including default, than higher quality debt securities. These securities pay
investors a higher interest rate because of the increased risk of loss. Although
certain floating rate loans are collateralized, there is no guarantee that the
value of the collateral will be sufficient to repay the loan. In a recession or
serious credit event, the Fund's net asset value could go down and you could
lose money.



(K) INDEMNIFICATIONS.  Under the Trust's organizational documents, its officers
and trustees are indemnified against certain liabilities that may arise out of
performance of their duties to the Trust. Additionally, in the normal course of
business, the Fund enters into contracts with third-party service providers that
contain a variety of representations and warranties and which provide general
indemnifications. The Fund's maximum exposure under these arrangements is
unknown, as this would involve future claims that may be made against the Fund
that have not yet occurred. Based on experience, management is of the view that
the risk of loss in connection with these potential indemnification obligations
is remote. However, there can be no assurance that material liabilities related
to such obligations will not arise in the future, which could adversely impact
the Fund.



(L) QUANTITATIVE DISCLOSURE OF DERIVATIVE HOLDINGS.  The following tables show
additional disclosures about the Fund's derivative and hedging activities,
including how such activities are accounted for and their effect on the Fund's
financial positions, performance and cash flows. These derivatives are not
accounted for as hedging instruments.

months ended April 30, 2010.

The Fund pays the Manager a monthly fee for services performed and facilities
furnished at an annual rate of the Fund's average daily net assets as follows:
0.60% on assets up to $1 billion and 0.575% on assets in excess of $1 billion.



The effective management fee rate (exclusive of any applicable
waivers/reimbursements) was 0.60% for the six-month period ended April 30, 2010.



For the six-month period ended April 30, 2010, New York Life Investments earned
fees from the Fund in the amount of $2,329,071.



State Street Bank and Trust Company ("State Street"), 1 Lincoln Street, Boston,
Massachusetts 02111, provides sub-administration and sub-accounting services to
the Fund pursuant to an agreement with New York Life Investments. These services
include calculating the daily NAVs of the Fund, maintaining the general ledger

assisting New York Life Investments in conducting various aspects of the Fund's
administrative operations. For providing these services to the Fund, State
Street is compensated by New York Life Investments.



(B) DISTRIBUTION AND SERVICE FEES.  The Trust, on behalf of the Fund, has
entered into a Distribution Agreement with NYLIFE Distributors LLC (the
"Distributor"), an


32    MainStay Floating Rate Fund







indirect, wholly-owned subsidiary of New York Life. The Fund has adopted
distribution plans, (the "Plans") in accordance with the provisions of Rule 12b-
1 under the 1940 Act.



Pursuant to the Investor Class and Class A Plans, the Distributor receives a
monthly distribution fee from the Investor Class and Class A shares at an annual
rate of 0.25% of the average daily net assets of the Investor Class and Class A
shares for distribution or service activities as designated by the Distributor.
Pursuant to the Class B and Class C Plans, Class B and Class C shares of the
Fund pay the Distributor a monthly distribution fee at an annual rate of 0.75%
of the average daily net assets of the Fund's Class B and Class C shares, along
with a service fee at an annual rate of 0.25% of the average daily net assets of
the Class B and Class C shares of the Fund for a total 12b-1 fee of 1.00%. Class
I shares are not subject to a distribution or service fee.



The Plans provide that the distribution and service fees are payable to the
Distributor regardless of the amounts actually expended by the Distributor for
distribution of the Fund's shares and service activities.



(C) SALES CHARGES.  The Fund was advised by the Distributor that the amount of
sales charges retained on sales of Investor Class and Class A shares was $4,336
and $37,527, respectively for the six-month period ended April 30, 2010. The
Fund was also advised that the Distributor retained contingent deferred sales
charges on redemptions of Investor Class, Class A, Class B and Class C shares of
$15, $5,517, $11,066 and $26,830, respectively, for the six-month period ended
April 30, 2010.

(E) SMALL ACCOUNT FEE.  Shareholders with small accounts adversely impact the
cost of providing transfer agency services. In an effort to reduce total
transfer agency expenses, the Fund has implemented a small account fee on
certain types of accounts. Certain shareholders with an account balance of less
than $1,000 are charged an annual per account fee of $20 (assessed semi-
annually). These fees are included in transfer agent fees shown on the Statement
of Operations.

Each of these commitments is available until the maturity date of the security.



NOTE 6--CUSTODIAN:



State Street is the custodian of the cash and the securities of the Fund.
Custodial fees are charged to the Fund based on the market value of securities
in the Fund and the number of certain cash transactions incurred by the Fund.



NOTE 7--LINE OF CREDIT:



The Fund and certain affiliated funds maintain a line of credit with a syndicate
of banks in order to secure a source of funds for temporary purposes to meet
unanticipated or excessive shareholder redemption requests.



The line of credit is in the amount of $125,000,000 and the commitment fee rate
is an annual rate of 0.10% of the average commitment amount, plus a 0.04% up-
front payment payable, regardless of usage, to The Bank of New York Mellon,
which serves as agent to the syndicate. The commitment fee and upfront payment
are allocated among certain MainStay Funds based upon net assets and other
factors. Interest on any revolving credit loan is charged based upon the Federal
Funds Advances rate or the one month LIBOR rate, whichever is higher. There were
no borrowings made or outstanding with respect to the Fund on the line of credit
during the six-month period ended April 30, 2010.



NOTE 8--PURCHASES AND SALES OF SECURITIES (IN 000'S):



During the six-month period ended April 30, 2010, purchases and sales of
securities, other than short-term securities, were $282,833 and $48,418
respectively.

(a) In addition to any automatic conversion features described above in Note 1
    with respect to Investor Class, Class A and B shares, you generally may also
    elect to convert your shares on a voluntary basis into another share class
    of the same fund for which you are eligible. However, the following
    limitations apply:



  - Investor Class and Class A shares that remain subject to a CDSC are
    ineligible for a voluntary conversion; and



  - All Class B and C shares are ineligible for a voluntary conversion.



These limitations do not impact any automatic conversion features described in
Note 1 with respect to Investor Class, Class A and B shares.



An investor or an investor's financial intermediary may contact the Fund to
request a voluntary conversion between shares classes of the same Fund. You may
be required to provide sufficient information to establish eligibility to
convert to the new share class. All permissible conversions will be made on the
basis of the relevant NAVs of the two classes without the imposition of any
sales load, fee or other charge. If you fail to remain eligible for the new
share class, you may automatically be converted back to your original share
class, or into another share class, if appropriate.



NOTE 10--NEW ACCOUNTING PRONOUNCEMENT:



In January 2010, the Financial Accounting Standards Board ("FASB") issued
Accounting Standards Update ("ASU") No. 2010-06 "Improving Disclosures about
Fair Value Measurements". ASU 2010-06 requires reporting entities to make new
disclosures about amount and reasons for significant transfers in and out of
Level 1 and Level 2 fair value measurements and input and valuation techniques
used to measure fair value for both recurring and nonrecurring fair value
measurements that fall in either Level 2 or Level 3, and information on
purchased, sales, issuances, and settlements in the roll forward of activity in
Level 3 fair value measures. The new and revised disclosure requirements are
effective for interim and annual reporting periods beginning after December 15,
2009 except for the disclosures about purchased, sales, issuances, and
settlements in the roll forward of activity in Level 3 fair value measures,
which are effective for fiscal years beginning after December 15, 2010. As of
April 30, 2010, the Fund has adopted ASU 2010-06. The adoption of ASU 2010-06
has not impacted the amounts reported in the financial statements; however,
there are additional disclosures in the Portfolio of Investments.



NOTE 11--SUBSEQUENT EVENTS:



In connection with the preparation of the financial statements of the Fund as of
and for the fiscal six-month period ended April 30, 2010, events and
transactions subsequent to April 30, 2010 through the date the financial
statements were issued have been evaluated by the Fund's management for possible
adjustment and/or disclosure. No subsequent events requiring financial statement
adjustment or disclosure have been identified.

        MESSAGE FROM THE PRESIDENT AND SEMIANNUAL REPORT

        Unaudited - April 30, 2010



MESSAGE FROM THE PRESIDENT

During the six months ended April 30, 2010, stock and bond markets generally
advanced, despite some volatility in January and February. Domestic small-cap
stocks were particularly strong, and U.S. stocks at all capitalization levels
provided double digit returns. Value stocks outpaced growth stocks for companies
of all sizes during the reporting period.

International stocks provided positive returns overall, but results varied
widely by country. Concerns about Greece's ability to meet its debt obligations
led many investors to abandon their holdings in Greece and question their
investments in several peripheral European nations where perceived risk had
increased. For the six-month reporting period, equities in the Far East
(including Japan) tended to be stronger than those in Europe.

The economic recovery in the United States continued. Real gross domestic
product advanced in the first quarter of 2010, though at a slower pace than in
the fourth quarter of 2009. The Federal Open Market Committee kept the targeted
federal funds rate at a historically low level throughout the reporting period,
which prompted many investors to leave the safety of U.S. Treasury securities in
search of higher yield.

In the high-yield bond market, lower-rated credits tended to be the strongest
performers. With investment-grade investors crossing into high-yield territory,
however, the highest-rated high-yield credits also saw strong demand. In the
municipal market, new-issue supply was reduced by government incentives that
encouraged municipal issuers to raise funds in the taxable market. In the
leveraged-loan market, new issuance strengthened, but extensive repayments
caused the market as a whole to contract.


Throughout the six-month reporting period, MainStay's portfolio managers sought
to make the most of market conditions within the investment strategies and risk
parameters of their respective Funds. While individual markets and Fund results
may vary, our pursuit of competitive returns over full market cycles has never
changed.

The information that follows provides a closer look
at the securities, strategies and market conditions that affected your MainStay
Fund(s) during the six months ended April 30, 2010. Of course, past performance
is no guarantee of future results. Even in a rising market, we believe that
maintaining a long-term perspective can be valuable. At MainStay, we believe
that in all markets, broad diversification, gradual allocation adjustments and
regular portfolio reviews can help guide you toward your long-range financial
goals.

We thank you for choosing MainStay Funds, and we look forward to serving your
investment needs for many years to come.

Sincerely,

/s/ STEPHEN P. FISHER

Stephen P. Fisher
President

1. Performance tables and graphs do not reflect the deduction of taxes that a
   shareholder would pay on distributions or Fund-share redemptions. Total
   returns reflect maximum applicable sales charges explained in this paragraph,
   change in share price, and reinvestment of dividend and capital gain
   distributions. The graphs assume an initial investment of $25,000 for Class A
   shares and $10,000 for all other classes and reflect the deduction of all
   sales charges that would have applied for the period of investment. Class A
   shares generally have a $25,000 minimum initial investment with no minimum
   subsequent purchase amount. For investors that, in the aggregate, have assets
   of $100,000 or more invested in any share classes of any of the MainStay
   Funds, the minimum initial investment is $15,000. Investor Class shares and
   Class A shares are sold with a maximum initial sales charge of 5.50% and an
   annual 12b-1 fee of 0.25%. Class B shares are sold with no initial sales
   charge, are subject to a contingent deferred sales charge ("CDSC") of up to
   5.00% if redeemed within the first six years of purchase, and have an annual
   12b-1 fee of 1.00%. Class C shares are sold with no initial sales charge, are
   subject to a CDSC of 1.00% if redeemed within one year of purchase, and have
   an annual 12b-1 fee of 1.00%. Class I shares are sold with no initial sales
   charge or CDSC, have no annual 12b-1 fee, and are generally available to
   corporate and institutional investors or individual investors with a minimum
   initial investment of $5 million. Performance figures reflect certain fee
   waivers and/or expense limitations, without which total returns may have been
   lower. For information on current fee waivers and/or expense limitations,

6    MainStay Growth Equity Fund



COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY GROWTH EQUITY FUND
(UNAUDITED)
- --------------------------------------------------------------------------------

The example below is intended to describe the fees and expenses borne by
shareholders during the six-month period from November 1, 2009, to April 30,
2010, and the impact of those costs on your investment.

EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, exchange fees, and sales charges (loads) on
purchases (as applicable), and (2) ongoing costs, including management fees,
distribution and/or service (12b-1) fees, and other Fund expenses (as
applicable). This example is intended to help you understand your ongoing costs
(in dollars) of investing in the Fund and to compare these costs with the
ongoing costs of investing in other mutual funds. The example is based on an
investment of $1,000 made at the beginning of the six-month period and held for
the entire period from November 1, 2009, to April 30, 2010.

This example illustrates your Fund's ongoing costs in two ways:

- - ACTUAL EXPENSES
The second and third data columns in the table below provide information about
actual account values and actual expenses. You may use the information in these
columns, together with the amount you invested, to estimate the expenses that
you paid during the six-months ended April 30, 2010. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number under the heading entitled "Expenses Paid
During Period" to estimate the expenses you paid on your account during this
period.

- - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The fourth and fifth data columns in the table below provide information about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense ratio and an assumed rate of return of 5% per year before expenses,
which is not the Fund's actual return. The hypothetical account values and
expenses may not be used to estimate the actual ending account balances or
expenses you paid for the six-month period shown. You may use this information
to compare the ongoing costs of investing in the Fund with the ongoing costs of
investing in other Funds. To do so, compare this 5% hypothetical example with
the 5% hypothetical examples that appear in the shareholder reports of the other
Funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as
redemption fees, if applicable, exchange fees, or sales charges (loads).
Therefore, the fourth and fifth data columns of the table are useful in
comparing ongoing costs only and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.

1. Expenses are equal to the Fund's annualized expense ratio of each class
   (1.52% for Investor Class, 1.21% for Class A, 2.27% for Class B and Class C
   and 0.97% for Class I) multiplied by the average account value over the
   period, divided by 365 and multiplied by 181 (to reflect the one-half year
   period). The table above represents the actual expenses incurred during the
   one-half year period.

8    MainStay Growth Equity Fund



PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

QUESTIONS ANSWERED BY PORTFOLIO MANAGER HARISH KUMAR, PHD, CFA, OF MADISON
SQUARE INVESTORS LLC, THE FUND'S SUBADVISOR.

HOW DID MAINSTAY GROWTH EQUITY FUND PERFORM RELATIVE TO ITS PEERS AND ITS
BENCHMARK DURING THE SIX MONTHS ENDED APRIL 30, 2010?

Excluding all sales charges, MainStay Growth Equity Fund returned 10.15% for
Investor Class shares, 10.29% for Class A shares, 9.62% for Class B shares and
9.73% for Class C shares for the six months ended April 30, 2010. Over the same
period, the Fund's Class I shares returned 10.49%. All share classes
underperformed the 14.71% return of the average Lipper(1) large-cap growth fund
and the 15.79% return of the Russell 1000(R) Growth Index(2) for the six months
ended April 30, 2010. The Russell 1000(R) Growth Index is the Fund's broad-based
securities-market index. See pages 5 and 6 for Fund returns with sales charges.

WHAT ACCOUNTED FOR THE FUND'S RELATIVE PERFORMANCE DURING THE REPORTING PERIOD?

The Fund underperformed the Russell 1000(R) Growth Index primarily because of
stock selection in the health care and consumer staples sectors.

DURING THE REPORTING PERIOD, WHICH INDUSTRIES WERE THE STRONGEST CONTRIBUTORS TO
THE FUND'S ABSOLUTE PERFORMANCE AND WHICH STOCKS WERE PARTICULARLY WEAK?

On an absolute basis, the industries that made the strongest contributions to
the Fund's performance were computers & peripherals, software and machinery.
Industries that detracted on an absolute basis included food & staples
retailing, capital markets and multiline retail.

DURING THE REPORTING PERIOD, WHICH STOCKS WERE STRONG PERFORMERS AND WHICH
STOCKS WERE WEAK?

The stocks that were the strongest contributors to the Fund's absolute
performance included information technology companies Apple and Microsoft and
rail transportation provider Union Pacific. On an absolute basis, major
detractors included retail drugstore chain CVS Caremark, digital wireless
telecommunications company Qualcomm and medical products supplier Baxter
International.

DID THE FUND MAKE ANY SIGNIFICANT PURCHASES OR SALES DURING THE REPORTING
PERIOD?

During the reporting period, we initiated new positions for the Fund in
diversified consumer products manufacturer Procter & Gamble and Internet
software & services provider Yahoo! Significant sales during the reporting
period included aerospace & defense company United Technologies and agricultural
chemicals manufacturer Monsanto.

HOW DID THE FUND'S SECTOR WEIGHTINGS CHANGE OVER THE COURSE OF THE REPORTING
PERIOD?

During the reporting period, we increased the Fund's weightings relative to the
Russell 1000(R) Growth Index in the health care and information technology
sectors. Over the same period, we decreased the Fund's weightings in consumer
discretionary and financials.

HOW WAS THE FUND POSITIONED AT THE END OF APRIL 2010, AND HOW DID THIS
POSITIONING AFFECT THE FUND'S PERFORMANCE?

The Fund's sector-group positioning is a result of our bottom-up stock selection
process rather than a top-down macroeconomic viewpoint. As of April 30, 2010,
the Fund was overweight relative to the Russell 1000(R) Growth Index in energy
and telecommunication services. Both of these positions helped the Fund's
relative performance during the reporting period. On the same date, the Fund
held underweight positions relative to the Russell 1000(R) Growth Index in
materials and consumer staples. During the reporting period, both of these
positions detracted from the Fund's performance relative to the benchmark.

NOTES TO FINANCIAL STATEMENTS UNAUDITED

NOTE 1--ORGANIZATION AND BUSINESS:

MainStay Funds Trust (the "Trust") is organized as a Delaware Statutory Trust
and is governed by a Declaration of Trust dated April 8, 2009. The Trust is
registered under the Investment Company Act of 1940, as amended (the "1940
Act"), as an open-end management investment company, and is comprised of twenty-
nine funds (collectively referred to as the "Funds"). These financial statements
and notes relate only to the MainStay Growth Equity Fund (the "Fund"), a
diversified fund. The Fund is the successor of the MainStay Growth Equity Fund,
a series of Eclipse Funds Inc. (the "Predecessor Fund"). The reorganization of
the Predecessor Fund with and into the Fund, which was not subject to
shareholder approval under applicable law, occurred on February 26, 2010. All
information regarding and references to periods prior to the commencement of
operations of the Fund relate to the Predecessor Fund.

The Fund currently offers five classes of shares. Class A shares, Class B
shares, Class C shares and Class I shares commenced operations on November 4,
2005. Investor Class shares commenced operations on February 28, 2008. Investor
Class and Class A shares are offered at net asset value ("NAV") per share plus
an initial sales charge. No sales charge applies on investments of $1 million or
more (and certain other qualified purchases) in Investor Class and Class A
shares, but a contingent deferred sales charge is imposed on certain redemptions
of such shares within one year of the date of purchase. Class B shares and Class
C shares are offered at NAV without an initial sales charge, although a
declining contingent deferred sales charge may be imposed on redemptions made
within six years of purchase of Class B shares and a 1.00% contingent deferred
sales charge may be imposed on redemptions made within one year of purchase of
Class C shares. Class I shares are offered at NAV and are not subject to a sales
charge. Depending upon eligibility, Investor Class shares may convert to Class A
shares and Class A shares may convert to Investor Class shares. The five classes
of shares have the same voting (except for issues that relate solely to one
class), dividend, liquidation and other rights, and the same terms and
conditions, except that Class B and Class C shares are subject to higher
distribution and/or service fee rates than Investor Class and Class A shares
under a distribution plan pursuant to Rule 12b-1 under the 1940 Act. Class I
shares are not subject to a distribution and/or service fee.

The Fund's investment objective is to seek long-term growth of capital.

principles generally accepted in the United States of America ("GAAP") and

(A) SECURITIES VALUATION.  Equity securities are valued at the latest quoted
sales prices as of the close of regular trading on the New York Exchange
("Exchange") (generally 4:00 p.m. Eastern time) on each day the Fund is open for
business ("valuation date"). Securities that are not traded on the valuation
date are valued at the mean of the latest quoted bid and asked prices. Prices
normally are taken from the principal market in which each security trades.
Investments in other mutual funds are valued at their NAVs as of the close of
the Exchange on the valuation date.

Temporary cash investments acquired over 60 days prior to maturity are valued
using the latest bid prices or using valuations based on a matrix system (which
considers such factors as security prices, yields, maturities, and ratings),
both as furnished by independent pricing services. Other temporary cash
investments which mature in 60 days or less ("short-term investments") are
valued at amortized cost. The amortized cost method involves valuing a security
at its cost on the date of purchase and thereafter assuming a constant
amortization to maturity of the difference between the principal amount due at
maturity and cost.

Securities for which market quotations are not readily available are valued by
methods deemed in good faith by the Fund's Board to represent fair value. Equity
and non-equity securities which may be valued in this manner include, but are
not limited to: (i) a security the trading for which has been halted or
suspended; (ii) a debt security that has recently gone into default and for
which there is not a current market quotation; (iii) a security of an issuer
that has entered into a restructuring; (iv) a security that has been de-listed
from a national exchange; (v) a security the market price of which is not
available from an independent pricing source or, if so provided, does not, in
the opinion of the Fund's Manager or Subadvisor, as defined in Note 3(A),
reflect the security's market value; and (vi) a security where the trading on
that security's principal market is temporarily closed at a time when, under
normal conditions, it would be open. At April 30, 2010, the Fund did not hold
securities that were valued in such a manner.

"Fair value" is defined as the price that the Fund would receive upon selling an
investment in an orderly transaction to an independent buyer in the principal or
most advantageous market of the investment. Fair value measurements are
determined within a framework that has established a three-tier hierarchy which
maximizes the use of observable market data and minimizes the use of
unobservable inputs to establish classification of fair value measurements for
disclosure purposes. "Inputs" refer broadly to the assumptions that market
participants would use in pricing the asset or liability, including assumptions
about risk, such as the risk inherent in a particular valuation technique used
to measure fair value using a pricing model and/or the risk inherent in the
inputs for the valuation technique. Inputs may be observable or unobservable.
Observable inputs are inputs that reflect the assumptions market participants


18    MainStay Growth Equity Fund



would use in pricing the asset or liability based on market data obtained from
sources independent of the reporting entity. Unobservable inputs are inputs that
reflect the reporting entity's own assumptions about the assumptions market
participants would use in pricing the asset or liability developed based on the
information available in the circumstances. The inputs or methodology used for
valuing securities may not be an indication of the risks associated with
investing in those securities. The three-tier hierarchy of inputs is summarized
in the three broad Levels listed below.

- - Level 1--quoted prices in active markets for identical investments

- - Level 2--other significant observable inputs (including quoted prices for
  similar investments in active markets, interest rates and yield curves,
  prepayment speeds, credit risks, etc.)

- - Level 3--significant unobservable inputs (including the Fund's own assumptions
  about the assumptions that market participants would use in determining the
  fair value of investments)

The aggregate value by input level, as of April 30, 2010, for the Fund's
investments is included at the end of the Fund's Portfolio of Investments.

The valuation techniques used by the Fund to measure fair value during the six-
month period ended April 30, 2010 maximized the use of observable inputs and
minimized the use of unobservable inputs. The Fund may have utilized some of the
following fair value techniques: multi-dimensional relational pricing models,
option adjusted spread pricing and estimating the price that would have
prevailed in a liquid market for an international equity security given
information available at the time of evaluation, when there are significant
events after the close of local foreign markets. For the six-month period ended
April 30, 2010, there have been no changes to the fair value methodologies.

(B) FEDERAL INCOME TAXES.   The Fund's policy is to comply with the requirements
of the Internal Revenue Code of 1986, as amended (the "Internal Revenue Code")
applicable to regulated investment companies and to distribute all of the
taxable income to the shareholders of the Fund within the allowable time limits.
Therefore, no federal income tax provision is required.

Management evaluates its tax positions to determine if the tax positions taken
meet the minimum recognition threshold in connection with accounting for
uncertainties in income tax positions taken or expected to be taken for the
purposes of measuring and recognizing tax liabilities in the financial
statements. Recognition of tax benefits of an uncertain tax position is required
only when the position is "more likely than not" to be sustained assuming
examination by taxing authorities. Management has analyzed the Fund's tax
positions taken on federal income tax returns for all open tax years (current
and prior three tax years), and has concluded that no provision for federal
income tax is required in the Fund's financial statements. The Fund's federal
and state income and federal excise tax returns for tax years for which the
applicable statutes of limitations have not expired are subject to examination
by the Internal Revenue Service and state departments of revenue.

(C) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS.  Dividends and distributions
are recorded on the ex-dividend date. The Fund intends to declare and pay
dividends of net investment income and distributions of net realized capital and
currency gains, if any, annually. Unless the shareholder elects otherwise, all
dividends and distributions are reinvested in the same class of shares of the
Fund, at NAV. Dividends and distributions to shareholders are determined in
accordance with federal income tax regulations and may differ from GAAP.

(D) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  The Fund records security
transactions on the trade date. Realized gains and losses on security
transactions are determined using the identified cost method. Dividend income is
recognized on the ex-dividend date and interest income is accrued as earned
using the effective interest rate method. Discounts and premiums on short-term
investments are accreted and amortized, respectively, on the straight-line
method.

Investment income and realized and unrealized gains and losses on investments of
the Fund are allocated to separate classes of shares pro rata based upon their
relative net assets on the date the income is earned or realized and unrealized
gains and losses are incurred.

(E) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred, except where direct allocations of expenses can be made. Expenses
(other than transfer agent expenses and fees incurred under the shareholder
services plans and the distribution plans further discussed in Note 3(B)) are
allocated to separate classes of shares pro rata based upon their relative NAV
on the date the expenses are incurred. The expenses borne by the Fund, including
those of related parties to the Fund, are shown in the Statement of Operations.

(F) USE OF ESTIMATES.  In preparing financial statements in conformity with
GAAP, management makes estimates and assumptions that affect the reported
amounts and disclosures in the financial statements. Actual results could differ
from those estimates.

(G) REPURCHASE AGREEMENTS.  The Fund may enter into repurchase agreements to
earn income. The Fund may enter into repurchase agreements only with financial
institutions that are deemed by the Manager or Subadvisor to be creditworthy,
pursuant to guidelines established by the Fund's Board. Repurchase agreements
are considered under

NOTES TO FINANCIAL STATEMENTS UNAUDITED (CONTINUED)


the 1940 Act to be collateralized loans by a Fund to the seller secured by the
securities transferred to the Fund.

When the Fund invests in repurchase agreements, the Fund's custodian takes
possession of the collateral pledged for investments in such repurchase
agreements. The underlying collateral is valued daily on a mark-to-market basis
to determine that the value, including accrued interest, exceeds the repurchase
price. In the event of the seller's default of the obligation to repurchase, the
Fund has the right to liquidate the collateral and apply the proceeds in
satisfaction of the obligation. Under certain circumstances, in the event of
default or bankruptcy by the other party to the agreement, realization and/or
retention of the collateral may be subject to legal proceedings and possible
realized loss to the Fund.

(H) SECURITIES LENDING.  In order to realize additional income, the Fund may
engage in securities lending, subject to the limitations set forth in the 1940
Act, and relevant guidance by the staff of the Securities and Exchange
Commission. In the event the Fund does engage in securities lending, the Fund
will lend through its custodian, State Street Bank and Trust Company ("State
Street"). State Street will manage the Fund's cash collateral in accordance with
the Lending Agreement between the Fund and State Street, and indemnify the
Fund's portfolio against counterparty risk. The loans will be collateralized by
cash or securities at least equal at all times to the market value of the
securities loaned. Collateral will consist of U.S. Government securities, cash
equivalents or irrevocable letters of credit. The Fund may bear the risk of
delay in recovery of, or loss of rights in, the securities loaned should the
borrower of the securities experience financial difficulty. The Fund may also
record realized gain or loss on securities deemed sold due to a borrower's
inability to return securities on loan. The Fund will receive compensation for
lending its securities in the form of fees or retain a portion of interest on
the investment of any cash received as collateral. The Fund also will continue
to receive interest and dividends on the securities loaned and any gain or loss
in the market price of the securities loaned that may occur during the term of
the loan will be for the account of the Fund.

Although the Fund and New York Life Investments (as defined in Note 3(A)) have
temporarily suspended securities lending, the Fund and New York Life Investments
reserve the right to reinstitute lending when deemed appropriate. The Fund had
no portfolio securities on loan as of April 30, 2010.

(I) INDEMNIFICATIONS.  Under the Trust's organizational documents, its officers
and trustees are indemnified against certain liabilities that may arise out of
performance of their duties to the Trust. Additionally, in the normal course of
business, the Fund enters into contracts with third-party service providers that
contain a variety of representations and warranties and which provide general
indemnifications. The Fund's maximum exposure under these arrangements is
unknown, as this would involve future claims that may be made against the Fund
that have not yet occurred. Based on experience, management is of the view that
the risk of loss in connection with these potential indemnification obligations
is remote. However, there can be no assurance that material liabilities related
to such obligations will not arise in the future, which could adversely impact
the Fund.

NOTE 3--FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER AND SUBADVISOR.  New York Life Investment Management LLC ("New York
Life Investments" or "Manager"), a registered investment adviser and an
indirect, wholly-owned subsidiary of New York Life Insurance Company ("New York
Life"), serves as the Fund's Manager, pursuant to a Management Agreement, as
amended ("Management Agreement"). The Manager provides offices, conducts
clerical, recordkeeping and bookkeeping services, and keeps most of the
financial and accounting records required to be maintained by the Fund. Except
for the portion of salaries and expenses that are the responsibility of the
Fund, the Manager also pays the salaries and expenses of all personnel
affiliated with the Fund and the operational expenses of the Fund. Madison
Square Investors LLC ("Madison Square Investors" or "Subadvisor"), a registered
investment adviser and an indirect, wholly-owned subsidiary of New York Life,
serves as Subadvisor to the Fund and is responsible for the day-to-day portfolio
management of the Fund. Pursuant to the terms of a Subadvisory Agreement between
New York Life Investments and the Subadvisor, New York Life Investments pays for
the services of the Subadvisor.

The Fund pays the Manager a monthly fee for services performed and facilities
furnished at an annual rate of the Fund's average daily net assets as follows:
0.70% on assets up to $500 million and 0.675% on assets over $500 million. The

waivers/reimbursements) was 0.70% for the six-month period ended April 30, 2010.

For the six-month period ended April 30, 2010, New York Life Investments earned
fees from the Fund in the amount of $1,796,776.

(B) DISTRIBUTION AND SERVICE FEES.  The Trust, on behalf of the Fund, has
entered into a Distribution Agreement with NYLIFE Distributors LLC (the
"Distributor"), an indirect, wholly-owned subsidiary of New York Life. The Fund
has adopted distribution plans, (the "Plans") in accordance with the provisions
of Rule 12b-1 under the 1940 Act.

Pursuant to the Investor Class and Class A Plans, the Distributor receives a
monthly distribution fee from the Investor Class and Class A shares at an annual
rate of 0.25% of the average daily net assets of the Investor Class and Class A
shares for distribution or service activities as designated by the Distributor.
Pursuant to the Class B and Class C Plans, Class B and Class C shares of the
Fund pay the Distributor a monthly distribution fee at an annual rate of 0.75%
of the average daily net assets of the Fund's Class B and Class C shares, along
with a service fee at an annual rate of 0.25% of the average daily net assets of
the Class B and Class C shares of the Fund for a total 12b-1 fee of 1.00%. Class
I shares are not subject to a distribution or service fee.

The Plans provide that the distribution and service fees are payable to the
Distributor regardless of the amounts actually expended by the Distributor for
distribution of the Fund's shares and service activities.

(C) SALES CHARGES.  The Fund was advised by the Distributor that the amount of
sales charges retained on sales of Investor Class and Class A shares were
$15,157 and $3,392, respectively, for the six-month period ended April 30, 2010.
The Fund was also advised that the Distributor retained contingent deferred
sales charges on redemptions of Class A, Class B and Class C shares of $641,
$72,225 and $163, respectively, for the six-month period ended April 30, 2010.

LLC has entered into an agreement with Boston Financial Data Services, Inc.
("BFDS") pursuant to which BFDS performs certain transfer agent services on
behalf of NYLIM Service Company LLC. Transfer agent expenses incurred by the
Fund for the six-month period ended April 30, 2010, were as follows:

(E) SMALL ACCOUNT FEE.  Shareholders with small accounts adversely impact the
cost of providing transfer agency services. In an effort to reduce total
transfer agency expenses, the Fund has implemented a small account fee on
certain types of accounts. Certain shareholders with an account balance of less
than $1,000 are charged an annual per account fee of $20 (assessed semi-
annually). These fees are included in transfer agent fees shown on the Statement
of Operations.

NOTE 9--FUND ACQUISITION:

At a meeting held on June 23, 2009, the Board of Trustees approved a plan of
reorganization where by the Fund would acquire the assets, including the
investments, and assume the identified liabilities of MainStay Capital
Appreciation Fund, a series of The MainStay Funds. Shareholders of the MainStay
Capital Appreciation Fund approved this reorganization on November 16, 2009,
which was then completed on November 24, 2009. The aggregate net assets of the
Fund immediately before the acquisition were $32,383,788 and the combined net
assets after the acquisition were $619,815,204.

The acquisition was accomplished by a tax-free exchange of the following:

In exchange for the MainStay Capital Appreciation Fund shares and net assets,
the Fund issued 25,405,384 Investor Class Shares; 21,838,919 Class A shares;
12,472,995 Class B shares; 313,217 Class C shares and 48,621 Class I shares.

MainStay Capital Appreciation Fund's net assets after adjustments for any
permanent book-to-tax differences at the acquisition date were as follows, which
include the following amounts of capital stock, unrealized appreciation,
accumulated net realized loss and undistributed net investment loss:

NOTES TO FINANCIAL STATEMENTS UNAUDITED (CONTINUED)

Assuming the acquisition had been completed on November 1, 2010, the beginning
of the annual reporting period of the Fund, the Fund's pro forma results of
operations for the period ended April 30, 2010, are as follows:

<Table>
                                  
Net investment loss                  $(1,417,792)
- ------------------------------------------------
Net gain on investments              $59,817,466
- ------------------------------------------------
Net increase in net assets
  resulting from operations          $58,399,674
- ------------------------------------------------

</Table>


Because the combined investment portfolios have been managed as a single
integrated portfolio since the acquisition was completed, it is not practicable
to separate the amounts of revenue and earnings of the MainStay Capital
Appreciation Fund that have been included in the Fund's Statement of Operations
since October 31, 2009.

In December 2007, the Financial Accounting Standards Board issued Accounting
Standards Codification (ASC) 805 (formerly FAS 141R Business Combinations),
which requires the following disclosures by the acquirer, among other things,
when a transaction or other event meets the definition of a business
combination:

- - The identification of the acquiree

- - Recognizing and measuring identifiable assets acquired and liabilities
  assumed, at the acquisition date, generally at their fair values

- - Disclosure, by the acquirer, of information that enables users of its
  financial statements to evaluate the nature and financial effect of a business
  combination that occurs during the current reporting period

ASC 805 requires prospective application to business combinations for which the
acquisition date occurs in an annual reporting period beginning on or after
December 15, 2008.

In accordance with ASC 805, for financial reporting purposes, assets received
and shares issued by the Fund were recorded at fair value; however, the cost
basis of the investments received from MainStay Capital Appreciation Fund was
carried forward to align ongoing reporting of the Fund's realized and unrealized
gains and losses with amounts distributable to shareholders for tax purposes.

ASC 805 requires disclosure in this semi-annual report, and in the Fund's annual
report as of October 31, 2010, of the Fund's pro-forma results of operations,
including net investment income, net gain (loss) on investments and net increase
(decrease) in net assets resulting from operations, assuming the acquisition had
been completed on November 1, 2009, the beginning of the annual reporting period
of the Fund, through the end of the applicable reporting period.

ASC 805 also requires the Fund to report, if practicable, the amounts of revenue
and earnings of the acquiree since the acquisition date included in the combined
entity's income statement for the reporting period. Because the combined
investment portfolios have been managed as a single integrated portfolio since
the acquisition was completed, it is not practicable to separate the amounts of
revenue and earnings of the MainStay Capital Appreciation Fund that will be
included in the Fund's Statement of Operations since November 24, 2009.

NOTE 10--NEW ACCOUNTING PRONOUNCEMENT:

In January 2010, the Financial Accounting Standards Board ("FASB") issued
Accounting Standards Update ("ASU") No. 2010-06 "Improving Disclosures about
Fair Value Measurements". ASU 2010-06 requires reporting entities to make new
disclosures about amount and reasons for significant transfers in and out of
Level 1 and Level 2 fair value measurements and input and valuation techniques
used to measure fair value for both recurring and nonrecurring fair value
measurements that fall in either Level 2 or Level 3, and information on
purchased, sales, issuances, and settlements in the roll forward of activity in
Level 3 fair value measures. The new and revised disclosure requirements are
effective for interim and annual reporting periods beginning after December 15,
2009 except for the disclosures about purchased, sales, issuances, and
settlements in the roll forward of activity in Level 3 fair value measures,
which are effective for fiscal years beginning after December 15, 2010.  As of
April 30, 2010, the Fund has adopted ASU 2010-06. The adoption of ASU 2010-06
has not impacted the amounts reported in the financial statements; however,
there are additional disclosures in the Portfolio of Investments.

NOTE 11--SUBSEQUENT EVENTS:

In connection with the preparation of the financial statements of the Fund as of
and for the fiscal six-month period ended April 30, 2010, events and
transactions subsequent to April 30, 2010 through the date the financial
statements were issued have been evaluated by the Fund's management for possible
adjustment and/or disclosure. No subsequent events requiring financial statement
adjustment or disclosure have been identified.

        MESSAGE FROM THE PRESIDENT AND SEMIANNUAL REPORT

        Unaudited - April 30, 2010



MESSAGE FROM THE PRESIDENT

During the six months ended April 30, 2010, stock and bond markets generally
advanced, despite some volatility in January and February. Domestic small-cap
stocks were particularly strong, and U.S. stocks at all capitalization levels
provided double digit returns. Value stocks outpaced growth stocks for companies
of all sizes during this period.

International stocks provided positive returns overall, but results varied
widely by country. Concerns about Greece's ability to meet its debt obligations
led many investors to abandon their holdings in Greece and question their
investments in several peripheral European nations where perceived risk had
increased. For the six months ended April 30, 2010, equities in the Far East
(including Japan) tended to be stronger than those in Europe.

The economic recovery in the United States continued. Real gross domestic
product advanced in the first quarter of 2010, though at a slower pace than in
the fourth quarter of 2009. The Federal Open Market Committee kept the targeted
federal funds rate at a historically low level throughout the six-month period,
which prompted many investors to leave the safety of U.S. Treasury securities in
search of higher yield.

In the high-yield bond market, lower-rated credits tended to be the strongest
performers. With investment-grade investors crossing into high-yield territory,
however, the highest-rated high-yield credits also saw strong demand. In the
municipal market, new-issue supply was reduced by government incentives that
encouraged municipal issuers to raise funds in the taxable market. In the
leveraged-loan market, new issuance strengthened, but extensive repayments
caused the market as a whole to contract.


During the period covered by this report, MainStay's portfolio managers sought
to make the most of market conditions within the investment strategies and risk
parameters of their respective Funds. While individual markets and Fund results
may vary, our pursuit of competitive returns over full market cycles has never
changed.

The information that follows provides a closer look
at the securities, strategies and market conditions that affected your MainStay
Fund(s) during the period covered by this report. Of course, past performance is
no guarantee of future results. Even in a rising market, we believe that
maintaining a long-term perspective can be valuable. At MainStay, we believe
that in all markets, broad diversification, gradual allocation adjustments and
regular portfolio reviews can help guide you toward your long-range financial
goals.

We thank you for choosing MainStay Funds, and we look forward to serving your
investment needs for many years to come.

Sincerely,

/s/ STEPHEN P. FISHER

Stephen P. Fisher
President

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY HIGH YIELD MUNICIPAL BOND
FUND (UNAUDITED)
- --------------------------------------------------------------------------------

The example below is intended to describe the fees and expenses borne by
shareholders during the period from March 31, 2010 to April 30, 2010, and the
impact of those costs on your investment.

EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, exchange fees, and sales charges (loads) on
purchases (as applicable), and (2) ongoing costs, including management fees,
distribution and/or service (12b-1) fees, and other Fund expenses (as
applicable). This example is intended to help you understand your ongoing costs
(in dollars) of investing in the Fund and to compare these costs with the
ongoing costs of investing in other mutual funds. The example is based on an
investment of $1,000 made at the beginning of the period and held for the entire
period from March 31, 2010 to April 30, 2010.

This example illustrates your Fund's ongoing costs in two ways:

- - ACTUAL EXPENSES
The second and third data columns in the table below provide information about
actual account values and actual expenses. You may use the information in these
columns, together with the amount you invested, to estimate the expenses that
you paid during the period ended April 30, 2010. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number under the heading entitled "Expenses Paid
During Period" to estimate the expenses you paid on your account during this
period.

- - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The fourth and fifth data columns in the table below provide information about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense ratio and an assumed rate of return of 5% per year before expenses,
which is not the Fund's actual return. The hypothetical account values and
expenses may not be used to estimate the actual ending account balances or
expenses you paid for the period shown. You may use this information to compare
the ongoing costs of investing in the Fund with the ongoing costs of investing
in other Funds. To do so, compare this 5% hypothetical example with the 5%
hypothetical examples that appear in the shareholder reports of the other Funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as
redemption fees, if applicable, exchange fees, or sales charges (loads).
Therefore, the fourth and fifth data columns of the table are useful in
comparing ongoing costs only and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.

1. Expenses are equal to the Fund's annualized expense ratio of each class
   (0.85% for Investor Class, 0.85% for Class A, 1.60% for Class C and 0.60% for
   Class I) multiplied by the average account value over the period, divided by
   365 and multiplied by 31 days for Investor Class, Class A, Class C and Class
   I (to reflect the since-inception period). The table above represents actual
   expenses incurred during the one-half year period.
2. Expenses paid during the period reflect ongoing costs for the period from
   inception through April 30, 2010. Had these shares been offered for the full
   six-month period ended April 30, 2010, and had the Fund provided a
   hypothetical 5% annualized return, expenses paid during the period would have
   been $4.26 for Investor Class, $4.31 for Class A, $8.05 for Class C and $3.01
   for Class I and the ending account value would have been $1,020.60 for
   Investor Class, $1,020.50 for Class A, $1,016.80 for Class C and $1,021.80
   for Class I.
3. Investor Class, Class A, Class C and Class I shares commenced operations on
   March 31, 2010.

8    MainStay High Yield Municipal Bond Fund



PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

QUESTIONS ANSWERED BY PORTFOLIO MANAGERS JOHN LOFFREDO, CFA, ROBERT DIMELLA,
CFA, AND MICHAEL PETTY OF MACKAY SHIELDS LLC, THE FUND'S SUBADVISOR.

HOW DID MAINSTAY HIGH YIELD MUNICIPAL BOND FUND PERFORM RELATIVE TO ITS PEERS
AND ITS BENCHMARK DURING THE PERIOD FROM THE FUND'S COMMENCEMENT ON MARCH 31,
2010, THROUGH APRIL 30, 2010?

Excluding all sales charges, MainStay High Yield Municipal Bond Fund returned
1.78% for Investor Class shares, 1.88% for Class A shares and 1.84% for Class C
shares from the Fund's commencement on March 31, 2010, through April 30, 2010.
Over the same period, the Fund's Class I shares returned 1.89%. All share
classes outperformed the 1.57% return of the average Lipper(1) high yield
municipal debt fund and the 1.22% return of the Barclays Capital Municipal Bond
Index(2) from March 31 through April 30, 2010. The Barclays Capital Municipal
Bond Index is the Fund's broad-based securities-market index. This Fund
commenced operations on March 31, 2010. See page 5 for Fund returns with sales
charges.

WHAT MAJOR FACTORS AFFECTED THE FUND DURING THE REPORTING PERIOD?

The most significant factors influencing the municipal market during the
reporting period were spread(3) tightening and the decrease in tax-exempt
supply. The Build America Bond program allowed municipal issuers to access the
taxable debt market with the federal government subsidizing a significant
portion of the interest expense over the life of the bonds. Since the program
made taxable issuance more affordable than municipal issuance, new issues in the
municipal market declined substantially.

During the reporting period, the main risk to the high-yield municipal bond
market was the potential for high-profile municipal defaults or bankruptcies.

WHAT FACTORS AFFECTED THE FUND'S PERFORMANCE RELATIVE TO ITS PEERS AND ITS
BENCHMARK DURING THE REPORTING PERIOD?

The Fund outperformed its peers and its benchmark during the reporting period
largely because of security selection and our ability to purchase bonds that had
higher coupon structures. Our investment decisions reflected initial purchases
for the Fund. We looked to build a widely diversified Fund with an emphasis on a
weighted average dollar price below par.

DURING THE REPORTING PERIOD, WHICH MARKET SEGMENTS WERE STRONG CONTRIBUTORS TO
THE FUND'S PERFORMANCE AND WHICH SEGMENTS DETRACTED?

On the basis of impact, which takes weightings and total returns into account,
the strongest-contributing market segments to the Fund's absolute performance
were tobacco, industrial development and health care bonds. The largest
detractor was a higher-than-normal exposure to cash equivalents during the
initial purchase phase, as these securities lagged the overall municipal market.

DID THE FUND MAKE ANY SIGNIFICANT PURCHASES OR SALES DURING THE REPORTING
PERIOD?

All purchases were significant, as we built all of the Fund's investment
portfolio during the reporting period. Although the Fund sold some cash
alternatives to build its investment portfolio, there were no other sales during
the reporting period.

statements are an integral part of, and should be read in conjunction with, the
financial statements.



NOTES TO FINANCIAL STATEMENTS UNAUDITED

NOTE 1--ORGANIZATION AND BUSINESS:

MainStay Funds Trust (the "Trust") is organized as a Delaware Statutory Trust
and is governed by a Declaration of Trust dated April 8, 2009. The Trust is
registered under the Investment Company Act of 1940, as amended (the "1940
Act"), as an open-end management investment company, and is comprised of twenty-
nine funds (collectively referred to as the "Funds"). These financial statements
and notes relate only to the MainStay High Yield Municipal Bond Fund (the
"Fund"), a diversified fund.

The Fund currently offers four classes of shares. Investor Class shares, Class A
shares, Class C shares and Class I shares commenced operations on March 31,
2010. Investor Class and Class A shares are offered at net asset value ("NAV")
per share plus an initial sales charge. No sales charge applies on investments
of $1 million or more (and certain other qualified purchases) in Investor Class
and Class A shares, but a contingent deferred sales charge is imposed on certain
redemptions of such shares within one year of the date of purchase. Class C
shares are offered at NAV without an initial sales charge, although a 1.00%
contingent deferred sales charge may be imposed on redemptions made within one
year of purchase of Class C shares. Class I shares are offered at NAV and are
not subject to a sales charge. Depending upon eligibility, Investor Class shares
may convert to Class A shares and Class A shares may convert to Investor Class
shares. The four classes of shares have the same voting (except for issues that
relate solely to one class), dividend, liquidation and other rights, and the
same terms and conditions, except that Class C shares are subject to higher
distribution and/or service fee rates than Investor Class and Class A shares
under a distribution plan pursuant to Rule 12b-1 under the 1940 Act. Class I
shares are not subject to a distribution and/or service fee.

The Fund's investment objective is to seek to a high level of income exempt from
Federal income taxes. Total return is a secondary objective.

NOTE 2--SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with accounting
principles generally accepted in the United States of America ("GAAP") and
follows the significant accounting policies described below.

(A) SECURITIES VALUATION.  Debt securities are valued at prices supplied by a
pricing agent or broker selected by the Fund's Manager (as defined in Note 3(A))
in consultation with the Fund's Subadvisor, if any (as defined in Note 3(A)),
whose prices reflect broker/dealer supplied valuations and electronic data
processing techniques, if such prices are deemed by the Fund's Manager, in
consultation with the Fund's Subadvisor, if any, to be representative of market
values, at the regular close of trading of the New York Stock Exchange
("Exchange") (generally 4:00 p.m. Eastern time) on each day the Fund is open for
business ("valuation date"). Futures contracts are valued at the last posted
settlement price on the market where such futures are primarily traded. Options
contracts are valued at the last posted settlement price on the market where
such options are principally traded.

Temporary cash investments acquired over 60 days prior to maturity are valued
using the latest bid prices or using valuations based on a matrix system (which
considers such factors as security prices, yields, maturities, and ratings),
both as furnished by independent pricing services. Other temporary cash
investments which mature in 60 days or less ("short-term investments") are
valued at amortized cost. The amortized cost method involves valuing a security
at its cost on the date of purchase and thereafter assuming a constant
amortization to maturity of the difference between the principal amount due at
maturity and cost.

Securities for which market quotations are not readily available are valued by
methods deemed in good faith by the Fund's Board to represent fair value. Equity
and non-equity securities which may be valued in this manner include, but are
not limited to: (i) a security the trading for which has been halted or
suspended; (ii) a debt security that has recently gone into default and for
which there is not a current market quotation; (iii) a security of an issuer
that has entered into a restructuring; (iv) a security that has been de-listed
from a national exchange; (v) a security the market price of which is not
available from an independent pricing source or, if so provided, does not, in
the opinion of the Fund's Manager or Subadvisor, as defined in Note 3(A),
reflect the security's market value; and (vi) a security where the trading on
that security's principal market is temporarily closed at a time when, under
normal conditions, it would be open. At April 30, 2010, the Fund did not hold
securities that were valued in such a manner.

"Fair value" is defined as the price that the Fund would receive upon selling an
investment in an orderly transaction to an independent buyer in the principal or
most advantageous market of the investment. Fair value measurements are
determined within a framework that has established a three-tier hierarchy which
maximizes the use of observable market data and minimizes the use of
unobservable inputs to establish classification of fair value measurements for
disclosure purposes. "Inputs" refer broadly to the assumptions that market
participants would use in pricing the asset or liability, including assumptions
about risk, such as the risk inherent in a particular valuation technique used
to measure fair value using a pricing model and/or the risk inherent in the
inputs for the valuation technique. Inputs may be observable or unobservable.
Observable inputs are inputs that reflect the assumptions market participants
would use in pricing the asset or liability developed based on market data
obtained from sources independent of the reporting entity. Unobservable inputs
are inputs that reflect the reporting entity's own assumptions about the
assumptions market participants would use in pricing the asset or

                                                   mainstayinvestments.com    17



NOTES TO FINANCIAL STATEMENTS UNAUDITED (CONTINUED)



liability developed based on the information available in the circumstances. The
inputs or methodology used for valuing securities may not be an indication of
the risks associated with investing in those securities. The three-tier
hierarchy of inputs is summarized in the three broad Levels listed below.

- - Level 1--quoted prices in active markets for identical investments

- - Level 2--other significant observable inputs (including quoted prices for
  similar investments in active markets, interest rates and yield curves,
  prepayment speeds, credit risks, etc.)

- - Level 3--significant unobservable inputs (including the Fund's own assumptions
  about the assumptions that market participants would use in determining the
  fair value of investments)

The aggregate value by input level, as of April 30, 2010, for the Fund's
investments is included at the end of the Fund's Portfolio of Investments.

The valuation techniques used by the Fund to measure fair value during the
period ended April 30, 2010 maximized the use of observable inputs and minimized
the use of unobservable inputs. The Fund may have utilized some of the following
fair value techniques: multi-dimensional relational pricing models, option
adjusted spread pricing and estimating the price that would have prevailed in a
liquid market for an international equity security given information available
at the time of evaluation, when there are significant events after the close of
local foreign markets. For the period ended April 30, 2010, there have been no
changes to the fair value methodologies.

(B) FEDERAL INCOME TAXES.  The Fund's policy is to comply with the requirements
of the Internal Revenue Code of 1986, as amended (the "Internal Revenue Code")
applicable to regulated investment companies and to distribute all of the
taxable income to the shareholders of the Fund within the allowable time limits.
Therefore, no federal income tax provision is required.

Management evaluates its tax positions to determine if the tax positions taken
meet the minimum recognition threshold in connection with accounting for
uncertainties in income tax positions taken or expected to be taken for the
purposes of measuring and recognizing tax liabilities in the financial
statements. Recognition of tax benefits of an uncertain tax position is required
only when the position is "more likely than not" to be sustained assuming
examination by taxing authorities. Management has analyzed the Fund's tax
positions taken on federal income tax returns for all open tax years (current
and prior three tax years), and has concluded that no provision for federal
income tax is required in the Fund's financial statements. The Fund's federal
and state income and federal excise tax returns for tax years for which the
applicable statutes of limitations have not expired are subject to examination
by the Internal Revenue Service and state departments of revenue.

(C) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS.  Dividends and distributions
are recorded on the ex-dividend date. The Fund intends to declare and pay
dividends of net investment income monthly and distributions of net realized
capital and currency gains, if any, annually, Unless the shareholder elects
otherwise, all dividends and distributions are reinvested in the same class of
shares of the Fund, at NAV. Dividends and distributions to shareholders are
determined in accordance with federal income tax regulations and may differ from
GAAP.

(D) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  The Fund records security
transactions on the trade date. Realized gains and losses on security
transactions are determined using the identified cost method. Interest income is
accrued as earned using the effective interest rate method. Discounts and
premiums on securities purchased, other than short-term investments, for the
Fund are accreted and amortized, respectively, on the effective interest rate
method over the life of the respective securities or, in the case of a callable
security, over the period to the first date of call. Discounts and premiums on
short-term investments are accreted and amortized, respectively, on the
straight-line method.

Investment income and realized and unrealized gains and losses on investments of
the Fund are allocated to separate classes of shares pro rata based upon their
relative net assets on the date the income is earned or realized and unrealized
gains and losses are incurred.

(E) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred, except where direct allocations of expenses can be made. Expenses
(other than transfer agent expenses and fees incurred under the shareholder
services plans and the distribution plans further discussed in Note 3(B)) are
allocated to separate classes of shares pro rata based upon their relative NAV
on the date the expenses are incurred. The expenses borne by the Fund, including
those of related parties to the Fund, are shown in the Statement of Operations.

(F) USE OF ESTIMATES.  In preparing financial statements in conformity with
GAAP, management makes estimates and assumptions that affect the reported
amounts and disclosures in the financial statements. Actual results could differ
from those estimates.

(G) PURCHASED AND WRITTEN OPTIONS.  The Fund may write covered call and put
options on its portfolio securities or foreign currencies. These securities are
subject to income price risk in the normal course of investing in these
transactions. Premiums received are recorded as assets, and the market value of
the written options are recorded as liabilities. The liabilities are
subsequently

18    MainStay High Yield Municipal Bond Fund



adjusted and unrealized appreciation or depreciation is recorded to reflect the
current value of the options written. Premiums received from writing options
that expire are treated as realized gains. Premiums received from writing
options that are exercised or are cancelled in closing purchase transactions are
added to the proceeds or netted against the amount paid on the transaction to
determine the realized gain or loss. By writing a covered call option, in
exchange for the premium, the Fund foregoes the opportunity for capital
appreciation above the exercise price should the price of the underlying
security or foreign currency increase. The Fund, in exchange for the premium,
accepts the risk of a decline in the market value of the underlying security or
foreign currency below the exercise price. A call option may be covered by the
call writer's owning the underlying security throughout the option period. A
call option may also be covered by the call writer's maintaining liquid assets
valued at greater than the exercise price of the call written. When writing a
covered call option, the Fund, in return for the premium on the option, gives up
the opportunity to profit from a price increase in the underlying securities
above the exercise price. However, as long as the obligation as the writer
continues, the Fund has retained the risk of loss should the price of the
underlying security decline. After writing a put option, the Fund may incur risk
exposure equal to the difference between the exercise price of the option and
the sum of the market value of the underlying security plus the premium received
from the sale of the option. The Fund writes covered call options to try to
realize greater return on the sale of a stock. The Fund writes put options to
help protect against unanticipated adverse developments.

The Fund may purchase call and put options on its portfolio securities or
foreign currencies. The Fund may purchase call options to protect against an
increase in the price of the security or foreign currency it anticipates
purchasing or to increase its current return. The Fund may purchase put options
on its securities or foreign currencies to protect against a decline in the
value of the security or foreign currency or to close out covered written put
positions. The Fund may also purchase options to seek to enhance returns. Risks
may arise from an imperfect correlation between the change in market value of
the securities or foreign currencies held by the Fund and the prices of options
relating to the securities or foreign currencies purchased or sold by the Fund
and from the possible lack of a liquid secondary market for an option. The
maximum risk exposure for any purchased option is limited to the premium
initially paid for the option. The Fund did not invest in purchased or written
options during the period ended April 30, 2010.

(H) REPURCHASE AGREEMENTS.  The Fund may enter into repurchase agreements to
earn income. The Fund may enter into repurchase agreements only with financial
institutions that are deemed by the Manager or Subadvisor to be creditworthy,
pursuant to guidelines established by the Fund's Board. Repurchase agreements
are considered under the 1940 Act to be collateralized loans by a Fund to the
seller secured by the securities transferred to the Fund.

When the Fund invests in repurchase agreements, the Fund's custodian takes
possession of the collateral pledged for investments in such repurchase
agreements. The underlying collateral is valued daily on a mark-to-market basis
to determine that the value, including accrued interest, exceeds the repurchase
price. In the event of the seller's default of the obligation to repurchase, the
Fund has the right to liquidate the collateral and apply the proceeds in
satisfaction of the obligation. Under certain circumstances, in the event of
default or bankruptcy by the other party to the agreement, realization and/or
retention of the collateral may be subject to legal proceedings and possible
realized loss to the Fund.

(I) FUTURES CONTRACTS.  A futures contract is an agreement to purchase or sell a
specified quantity of an underlying instrument at a specified future date and
price, or to make or receive a cash payment based on the value of a financial
instrument (e.g., foreign currency, interest rate, security, or securities
index.) The Fund is subject to equity price risk and interest rate risk in the
normal course of investing in these transactions. The Fund enters into futures
contracts for hedging purposes, managing the duration and yield curve profile,
market exposure or to enhance income. During the period the futures contract is
open, changes in the value of the contract are recognized as unrealized gains or
losses by "marking to market" such contract on a daily basis to reflect the
market value of the contract at the end of each day's trading. A Fund agrees to
receive from or pay to the broker an amount of cash equal to the daily
fluctuation in the value of the contract. Such receipts or payments are known as
"variation margin". When the futures contract is closed, the Fund records a
realized gain or loss equal to the difference between the proceeds from (or cost
of) the closing transaction and the Fund's basis in the contract.

The use of futures contracts involves, to varying degrees, elements of market
risk in excess of the amount recognized in the Statement of Assets and
Liabilities. The contract or notional amounts and variation margin reflect the
extent of the Fund's involvement in open futures positions. Risks arise from the
possible imperfect correlation in movements in the price of futures contracts,
interest rates and the underlying hedged assets, and the possible inability of
counterparties to meet the terms of their contracts. However, the Fund's
activities in futures contracts have minimal counterparty risk as they are
conducted through regulated exchanges that guarantee the futures against default
by the counterparty. The Fund invests in futures contracts to help manage the
duration and yield curve of the portfolio. The Fund's investment in futures
contracts and other derivatives may increase the volatility of the Fund's NAV
and may result

NOTES TO FINANCIAL STATEMENTS UNAUDITED (CONTINUED)



in a loss to the Fund. The Fund did not invest in futures contracts during the
period ended April 30, 2010.

(J) SWAP AGREEMENTS.  The Fund enters into interest rate swap agreements
("swaps") for the purpose of attempting to protect against changes in interest
rates or for other portfolio management purposes. In a standard swaps
transaction, two parties agree to exchange the returns (or differentials in
rates of return) earned or realized on particular predetermined investments or
instruments. The gross returns to be exchanged or "swapped" between the parties
are calculated with respect to a notional amount. Credit default swaps are
contracts whereby one party makes periodic payments to a counterparty in
exchange for the right to receive a specified return in the event of a default
by a third party on its obligation. Credit default swaps may be used to provide
a measure of protection against defaults of sovereign or corporate issuers. In
connection with these agreements, cash or securities may be set aside as
collateral in accordance with the terms of the swap agreement.

In a typical cap or floor agreement, one party agrees to make payments only
under specified circumstances, usually in return for payment of a fee by the
other party. For example, the buyer of an interest rate cap obtains the right to
receive payments to the extent that a specified interest rate exceeds an agreed-
upon level, while the seller of an interest rate floor is obligated to make
payments to the extent that a specified interest rate falls below an agreed-upon
level. An interest rate collar combines elements of buying a cap and selling a
floor.

The Fund bears the risk of loss of the amount expected to be received under a
swap agreement in the event of the default or bankruptcy of a swap agreement
counterparty. The Fund may be able to eliminate its exposure under a swap
agreement either by assignment or other disposition, or by entering into an
offsetting swap agreement with the same party or a similarly creditworthy party.

Swaps are marked to market daily based upon quotations from market makers and
vendors and the change in value, if any, is recorded as unrealized gain or loss.
Payments received or made on swap contracts are recorded as realized gain or
loss. Gains or losses are realized upon early termination of the swap
agreements. These financial instruments are not actively traded on financial
markets. Entering into these agreements involves elements of credit, market and
documentation risk in excess of the amounts recognized on the Statement of
Assets and Liabilities. Such risks involve the possibility that there will be no
liquid market for these agreements, that the counterparty to the agreements may
default on its obligation to perform or disagree as to the meaning of the
contractual terms in the agreements and that there may be unfavorable changes in
interest rates or the price of the index or security underlying these
transactions. The Fund did not hold securities that were valued in such a
manner. The Fund did not invest in swap contracts during the period ended April
30, 2010.

(K) CONCENTRATION OF RISK.  The ability of issuers of debt securities held by
the Fund to meet their obligations may be affected by economic or political
developments in a specific country, industry or region.

(L) OFFERING COSTS.  Costs incurred by the Fund in connection with the
commencement of the Fund's operations were being amortized on a straight line
basis over twelve months.

(M) INDEMNIFICATIONS.  Under the Trust's organizational documents, its officers
and trustees are indemnified against certain liabilities that may arise out of
performance of their duties to the Trust. Additionally, in the normal course of
business, the Fund enters into contracts with third-party service providers that
contain a variety of representations and warranties and which provide general
indemnifications. The Fund's maximum exposure under these arrangements is
unknown, as this would involve future claims that may be made against the Fund
that have not yet occurred. Based on experience, management is of the view that
the risk of loss in connection with these potential indemnification obligations
is remote. However, there can be no assurance that material liabilities related
to such obligations will not arise in the future, which could adversely impact
the Fund.

NOTE 3--FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER AND SUBADVISOR.  New York Life Investment Management LLC ("New York
Life Investments" or "Manager"), a registered investment adviser and an
indirect, wholly-owned subsidiary of New York Life Insurance Company ("New York
Life"), serves as the Fund's Manager, pursuant to a Management Agreement, as
amended ("Management Agreement"). The Manager provides offices, conducts
clerical, recordkeeping and bookkeeping services, and keeps most of the
financial and accounting records required to be maintained by the Fund. Except
for the portion of salaries and expenses that are the responsibility of the
Fund, the Manager also pays the salaries and expenses of all personnel
affiliated with the Fund and the operational expenses of the Fund. MacKay
Shields LLC (the "Subadvisor"), a registered investment adviser and an indirect,
wholly-owned subsidiary of New York Life, serves as Subadvisor to the Fund and
is responsible for the day-to-day portfolio management of the Fund. Pursuant to
the terms of a Subadvisory Agreement between New York Life Investments and the
Subadvisor, New York Life Investments pays for the services of the Subadvisor.

The Fund pays the Manager a monthly fee for services performed and facilities
furnished at an annual rate of 0.55% of the Fund's average daily net assets.

Effective March 30, 2010, New York Life Investments entered into a written
expense limitation agreement under

20    MainStay High Yield Municipal Bond Fund



which it has agreed to waive a portion of the management fee or reimburse
expenses to the extent necessary to ensure that the total ordinary operating
expenses (total ordinary operating expenses excludes taxes, interest,
litigation, extraordinary expenses, brokerage, other transaction expenses
relating to the purchase or sale of portfolio investments, and the fees and
expenses of any other funds in which the Fund invests) for the Fund's Class A
shares do not exceed 0.85% of its average net assets. New York Life Investments
will apply an equivalent waiver or reimbursement, in an equal number of basis
points, to the other share classes of the Fund. This agreement expires on March
31, 2011 and it reviewed annually by the Board in connection with its review of
the Fund's advisory agreements. Based on its review, the Board may agree to
maintain, modify or terminate the agreement.

For the period ended April 30, 2010, New York Life Investments earned fees from
the Fund in the amount of $4,897 and waived/reimbursed its fees in the amount of
$22,837.

State Street Bank and Trust Company ("State Street"), 1 Lincoln Street, Boston,
Massachusetts 02111, provides sub-administration and sub-accounting services to
the Fund pursuant to an agreement with New York Life Investments. These services
include calculating the daily NAVs of the Fund, maintaining the general ledger
and sub-ledger accounts for the calculation of the Fund's respective NAVs, and
assisting New York Life Investments in conducting various aspects of the Fund's
administrative operations. For providing these services to the Fund, State
Street is compensated by New York Life Investments.

(B) DISTRIBUTION AND SERVICE FEES.  The Trust, on behalf of the Fund, has
entered into a Distribution Agreement with NYLIFE Distributors LLC (the
"Distributor"), an indirect, wholly-owned subsidiary of New York Life. The Fund
has adopted distribution plans, (the "Plans") in accordance with the provisions
of Rule 12b-1 under the 1940 Act.

Pursuant to the Investor Class and Class A Plans, the Distributor receives a
monthly distribution fee from the Fund at an annual rate of 0.25% of the average
daily net assets of the Fund's Investor Class and Class A shares, which is an
expense of the Investor Class and Class A shares of the Fund for distribution or
service activities as designated by the Distributor. Pursuant to the Class C
Plans, the Fund pays the Distributor a monthly distribution fee, which is an
expense of the Class C shares of the Fund, at the annual rate of 0.75% of the
average daily net assets of the Fund's Class C shares, along with a shareholder
service fee at the annual rate of 0.25% of the average daily net assets of the
Class C shares of the Fund for a total 12b-1 fee of 1.00%.  Class I shares are
not subject to a distribution or service fee.

The Plans provide that the distribution and service fees are payable to the
Distributor regardless of the amounts actually expended by the Distributor for
distribution of the Fund's shares and service activities.

(C) SALES CHARGES.  The Fund was advised by the Distributor that the amount of
sales charges retained on sales of Investor Class and Class A shares was $132
and $1,160, respectively, for the period ended April 30, 2010.

(D) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT.  NYLIM
Service Company LLC, an affiliate of New York Life Investments, is the Fund's
transfer, dividend disbursing and shareholder servicing agent pursuant to an
agreement between NYLIM Service Company LLC and the Trust. NYLIM Service Company
LLC has entered into an agreement with Boston Financial Data Services, Inc.
("BFDS") pursuant to which BFDS performs certain transfer agent services on
behalf of NYLIM Service Company LLC. The Fund did not incur any transfer agent
expenses for the period ended April 30, 2010.

(E) SMALL ACCOUNT FEE.  Shareholders with small accounts adversely impact the
cost of providing transfer agency services. In an effort to reduce total
transfer agency expenses, the Fund has implemented a small account fee on
certain types of accounts. Certain shareholders with an account balance of less
than $1,000 are charged an annual per account fee of $20 (assessed semi-
annually). These fees are included in transfer agent fees shown on the Statement
of Operations.

(F) CAPITAL.  At April 30, 2010, New York Life and its affiliates beneficially
held shares of the Fund with the following values and percentages of net assets
as follows:

<Table>

- ---------------------------------------------------

</Table>


(G) OTHER.  Pursuant to the Management Agreement, a portion of the cost of legal
services provided to the Fund by the Office of the General Counsel of New York
Life Investments is payable directly by the Fund. For the period ended April 30,
2010, these fees, which are included in professional fees shown on the Statement
of Operations, were $149.

NOTE 4--CUSTODIAN:

State Street is the custodian of the cash and the securities of the Fund.
Custodial fees are charged to the Fund based on the market value of securities

NOTE 7--NEW ACCOUNTING PRONOUNCEMENT:

In January 2010, the Financial Accounting Standards Board ("FASB") issued
Accounting Standards Update ("ASU") No. 2010-06 "Improving Disclosures about
Fair Value Measurements". ASU 2010-06 requires reporting entities to make new
disclosures about amount and reasons for significant transfers in and out of
Level 1 and Level 2 fair value measurements and input and valuation techniques
used to measure fair value for both recurring and nonrecurring fair value
measurements that fall in either Level 2 or Level 3, and information on
purchased, sales, issuances, and settlements in the roll forward of activity in
Level 3 fair value measures. The new and revised disclosure requirements are
effective for interim and annual reporting periods beginning after December 15,
2009 except for the disclosures about purchased, sales, issuances, and
settlements in the roll forward of activity in Level 3 fair value measures,
which are effective for fiscal years beginning after December 15, 2010. As of
April 30, 2010, the Fund has adopted ASU 2010-06. The adoption of ASU 2010-06
has not impacted the amounts reported in the financial statements; however,
there are additional disclosures in the Portfolio of Investments.

NOTE 8--SUBSEQUENT EVENTS:

In connection with the preparation of the financial statements of the Fund as of
and for the fiscal period ended April 30, 2010, events and transactions
subsequent to April 30, 2010 through the date the financial statements were

22    MainStay High Yield Municipal Bond Fund



BOARD CONSIDERATION AND APPROVAL OF MANAGEMENT AGREEMENT AND SUBADVISORY
AGREEMENT

Section 15(c) of the Investment Company Act of 1940, as amended (the "1940 Act")
requires that each mutual fund's board of trustees, including a majority of
trustees who are not "interested persons" of the fund, as defined in the 1940
Act ("Independent Trustees"), annually review and approve the fund's investment
advisory agreements. At its March 15-16, 2010 meeting, the Board of
Directors/Trustees of the MainStay Group of Funds ("Board") unanimously approved
the Management Agreement between the MainStay High Yield Municipal Bond Fund
("Fund") and New York Life Investment Management LLC ("New York Life
Investments"), and the Subadvisory Agreement between New York Life Investments
and MacKay Shields LLC ("MacKay Shields") on behalf of the Fund.

In reaching its decisions to approve the Agreements set forth above (the
"Agreements"), the Board considered information prepared specifically in
connection with the contract review process that took place in advance of its
March 2010 meeting, which included responses from New York Life Investments and
MacKay Shields to a comprehensive list of questions encompassing a variety of
topics prepared on behalf of the Board by independent legal counsel to the
Board. The Board also considered relevant information previously provided to the
Board in connection with its review of the investment advisory agreements for
other MainStay Funds.

In determining to approve the Agreements, the members of the Board reviewed and
evaluated all of the information and factors they believed to be relevant and
appropriate in light of legal advice furnished to them by independent legal
counsel and through the exercise of their own business judgment. The broad
factors considered by the Board are discussed in greater detail below, and
included, among other things: (i) the nature, extent, and quality of the
services to be provided to the Fund by New York Life Investments and MacKay
Shields; (ii) the qualifications of the proposed portfolio managers for the Fund
and the historical investment performance of products previously managed by such
portfolio managers with similar investment strategies to the Fund; (iii) the
anticipated costs of the services to be provided, and profits expected to be
realized, by New York Life Investments and its affiliates, including MacKay
Shields as subadviser to the Fund, from their relationship with the Fund; (iv)
the extent to which economies of scale may be realized as the Fund grows, and
the extent to which economies of scale may benefit Fund investors; and (v) the
reasonableness of the Fund's proposed management and subadvisory fee levels and
overall total ordinary operating expenses, particularly as compared to similar
funds and portfolios.

While individual members of the Board may have weighed certain factors
differently, the Board's decisions to approve the Agreements were based on a
comprehensive consideration of all the information provided to the Board,
including information provided to the Board specifically in connection with the
contract review processes. In addition to considering the above-referenced
factors, the Board observed that in the marketplace there are a range of
investment options available to future shareholders of the Fund, and that such
shareholders, having had the opportunity to consider alternative investment
products and services, will have chosen to invest in the Fund. A more detailed
discussion of the factors that figured prominently in the Board's decisions to
approve the Agreements is provided below.

NATURE, EXTENT AND QUALITY OF SERVICES TO BE PROVIDED BY NEW YORK LIFE
INVESTMENTS AND MACKAY SHIELDS

In considering the approval of the Agreements, the Board examined the nature,
extent and quality of the services that New York Life Investments proposed to
provide to the Fund. The Board evaluated New York Life Investments' experience
in serving as manager of other mutual funds, a variety of other investment
advisory clients, including other pooled investment vehicles, and experience
with overseeing affiliated and non-affiliated subadvisers. The Board considered
the experience of senior personnel at New York Life Investments proposed to
provide management and administrative services to the Fund, as well as New York
Life Investments' reputation and financial condition. The Board considered New
York Life Investments' performance in fulfilling its responsibilities for
overseeing the legal and compliance environment of the MainStay Group of Funds
generally, including its oversight of MacKay Shields' compliance with the
policies and investment objectives of other MainStay Funds, and New York Life
Investments' performance with respect to the implementation of Board directives
regarding other MainStay Funds. In addition, the Board noted that New York Life
Investments also is responsible for paying all of the salaries and expenses for
the Fund's officers. The Board also considered the benefits to shareholders of
being part of the MainStay Group of Funds, including the privilege of exchanging
investments between the same class of shares without the imposition of a sales
charge, as described more fully in the Fund's prospectus.

The Board also examined the nature, extent and quality of the services that
MacKay Shields proposed to provide to the Fund. The Board evaluated MacKay
Shields' experience in serving as subadviser to other mutual funds under the
Board's supervision and managing other portfolios, including those with similar
investment strategies to the Fund. It examined MacKay Shields' track record and
experience in providing investment advisory services, the experience of
investment advisory, senior management and administrative personnel at MacKay
Shields, and MacKay Shields' overall legal and compliance environment. The Board
also reviewed MacKay Shields' willingness to invest in personnel designed to
benefit the Fund. In this regard, the Board considered the experience of the
Fund's proposed portfolio

                                                   mainstayinvestments.com    23



managers, including with respect to other products with similar investment
strategies to the Fund, the number of accounts managed by the portfolio managers
and the method for compensating portfolio managers.

Based on these considerations, the Board concluded, within the context of its
overall determinations regarding the Agreements, that the Fund likely would
benefit from the nature, extent and quality of these services as a result of New
York Life Investments' and MacKay Shields' experience, personnel, operations and
resources.

INVESTMENT PERFORMANCE

In connection with the Board's consideration of the Agreements, the Board noted
that the Fund had no investment performance track record since the Fund had not
yet been offered to shareholders. The Board discussed with management and the
Fund's proposed portfolio management team the Fund's investment process,
strategies and risks. Additionally, the Board considered the historical
performance of other investment portfolios with similar investment strategies
that are or have been managed by the proposed portfolio managers for the Fund.
Based on these considerations, the Board concluded that the Fund was likely to
be managed responsibly and capably by MacKay Shields.

COSTS OF THE SERVICES PROVIDED, AND PROFITS TO BE REALIZED, BY NEW YORK LIFE
INVESTMENTS AND MACKAY SHIELDS

The Board considered the anticipated costs of the services to be provided by New
York Life Investments and MacKay Shields under the Agreements, and the profits
expected to be realized by New York Life Investments and its affiliates due to
their relationships with the Fund. Because MacKay Shields is an affiliate of New
York Life Investments whose subadvisory fees are paid directly by New York Life
Investments, the Board considered expected cost and profitability information
for New York Life Investments and MacKay Shields in the aggregate.

In evaluating the costs and profits of New York Life Investments and its
affiliates, including MacKay Shields, due to their relationships with the Fund,
the Board considered, among other things, each party's investments in personnel,
systems, equipment and other resources necessary to manage the Fund, and the
fact that New York Life Investments will be responsible for paying the
subadvisory fees for the Fund. The Board acknowledged that New York Life
Investments and MacKay Shields must be in a position to pay and retain
experienced professional personnel to provide services to the Fund, and that New
York Life Investments' ability to maintain a strong financial position is
important in order for New York Life Investments to continue to provide high-
quality ongoing services to the Fund. The Board noted, for example, increased
costs borne by New York Life Investments and its affiliates due to new and
ongoing regulatory and compliance requirements. The Board also noted that the
Fund will benefit from the allocation of certain fixed costs across the MainStay
Group of Funds.

The Board also reviewed information from New York Life Investments and its
affiliates regarding their anticipated profitability due to their overall
relationships with the Fund. For New York Life Investments and MacKay Shields,
the Board considered information illustrating the revenues and expenses to be
allocated to the Fund.

The Board noted the difficulty in obtaining reliable comparative data about
mutual fund managers' profitability, since such information generally is not
publicly available and may be impacted by numerous factors, including the
structure of a fund manager's organization, the types of funds it manages, and
the manager's capital structure and costs of capital. While recognizing the
difficulty in evaluating a manager's profitability with respect to the Fund, and
noting that other profitability methodologies may also be reasonable, the Board
concluded that the profitability methodology presented by New York Life
Investments to the Board with respect to the Fund was reasonable in all material
respects.

In considering the anticipated costs and profitability of the Fund, the Board
also considered certain fall-out benefits that may be realized by New York Life
Investments and its affiliates due to their relationships with the Fund. The
Board further considered that, in addition to fees earned by New York Life
Investments for managing the Fund, New York Life Investments' affiliates would
also earn revenues from serving the Fund in various other capacities, including
as the Fund's transfer agent and distributor. The information provided to the
Board indicated that the profitability to New York Life Investments and its
affiliates arising directly from these other arrangements would not be
excessive. The Board noted that, although it assessed the overall profitability
of the Fund to New York Life Investments and its affiliates as part of the
annual contract review process, when considering the reasonableness of the fees
to be paid to New York Life Investments and its affiliates under the Agreements,
the Board considered the profitability of New York Life Investments'
relationship with the Fund on a pre-tax basis, and without regard to
distribution expenses.

After evaluating the information presented to the Board, the Board concluded,
within the context of its overall determinations regarding the Agreements, that
the profits expected to be realized by New York Life Investments and its
affiliates (including MacKay Shields) due to their relationships with the Fund
would be fair and reasonable.

BOARD CONSIDERATION AND APPROVAL OF MANAGEMENT AGREEMENT AND SUBADVISORY
AGREEMENT (CONTINUED)



EXTENT TO WHICH ECONOMIES OF SCALE MAY BE REALIZED AS THE FUND GROWS

The Board also considered whether the Fund's proposed expense structure
permitted economies of scale to be shared with Fund investors. The Board
reviewed information from New York Life Investments showing how the Fund's
management fee hypothetically would compare with fees paid for similar services
by peer funds at varying asset levels. The Board noted the extent to which the
Fund will benefit from expense waivers or reimbursements. While recognizing that
any precise determination of future economies of scale is necessarily
subjective, the Board considered the extent to which New York Life Investments
and MacKay Shields may realize a larger profit margin as the Fund's assets grow
over time.

Based on this information, the Board concluded, within the context of its
overall determinations regarding the Agreements, that the Fund's expense
structure appropriately reflects economies of scale for the benefit of Fund
investors. The Board noted, however, that it would continue to evaluate the
reasonableness of the Fund's expense structure as the Fund grows over time,
including considering the imposition of breakpoints as the Fund's assets grow
over time.

MANAGEMENT AND SUBADVISORY FEES AND TOTAL ORDINARY OPERATING EXPENSES

The Board evaluated the reasonableness of the fees to be paid under the
Agreements and the Fund's anticipated total ordinary operating expenses. The
Board primarily considered the reasonableness of the overall management fees to
be paid by the Fund to New York Life Investments, since the fees to be paid to
MacKay Shields will be paid by New York Life Investments, not the Fund. The
Board also considered the impact of the Fund's contractual expense limitation
arrangements pursuant to which New York Life Investments has agreed to limit the
Fund's total ordinary operating expenses.

In assessing the reasonableness of the Fund's fees and expenses, the Board
considered comparative data provided by New York Life Investments with respect
to the fees and expenses charged by similar mutual funds managed by other
investment advisers. In addition, the Board considered information provided by
New York Life Investments and MacKay Shields on fees charged to other investment
advisory clients, including institutional separate accounts and other funds with
similar investment objectives as the Fund. In this regard, the Board took into
account explanations from New York Life Investments and MacKay Shields about the
different scope of services provided to retail mutual funds as compared with
other investment advisory clients.

After considering all of the factors outlined above--including the
reasonableness of the Fund's proposed management fee, share class structure and
transfer agent fee schedule--the Board accepted New York Life Investments'
proposed expense limitations on the Fund's share classes. The Board further
acknowledged that New York Life Investments may determine voluntarily to waive
expenses of Fund share classes. Based on these considerations, the Board also
concluded that the Fund's management and subadvisory fees and anticipated total
ordinary operating expenses were within a range that is competitive and, within
the context of the Board's overall conclusions regarding the Agreements, support
a conclusion that these fees and expenses are reasonable.

CONCLUSION

On the basis of the information provided to it and its evaluation thereof, the
Board, including the Independent Trustees, unanimously voted to approve the
Agreements.

        MESSAGE FROM THE PRESIDENT AND SEMIANNUAL REPORT

        Unaudited - April 30, 2010

        MainStay ICAP Equity Fund
        MainStay ICAP Select Equity Fund
        MainStay ICAP Global Fund
        MainStay ICAP International Fund



MESSAGE FROM THE PRESIDENT

During the six months ended April 30, 2010, stock and bond markets generally
advanced, despite some volatility in January and February. Domestic small-cap
stocks were particularly strong, and U.S. stocks at all capitalization levels
provided double digit returns. Value stocks outpaced growth stocks for companies
of all sizes during the reporting period.

International stocks provided positive returns overall, but results varied
widely by country. Concerns about Greece's ability to meet its debt obligations
led many investors to abandon their holdings in Greece and question their
investments in several peripheral European nations where perceived risk had
increased. For the six-month reporting period, equities in the Far East
(including Japan) tended to be stronger than those in Europe.

The economic recovery in the United States continued. Real gross domestic
product advanced in the first quarter of 2010, though at a slower pace than in
the fourth quarter of 2009. The Federal Open Market Committee kept the targeted
federal funds rate at a historically low level throughout the reporting period,
which prompted many investors to leave the safety of U.S. Treasury securities in
search of higher yield.

In the high-yield bond market, lower-rated credits tended to be the strongest
performers. With investment-grade investors crossing into high-yield territory,
however, the highest-rated high-yield credits also saw strong demand. In the
municipal market, new-issue supply was reduced by government incentives that
encouraged municipal issuers to raise funds in the taxable market. In the
leveraged-loan market, new issuance strengthened, but extensive repayments
caused the market as a whole to contract.


Throughout the six-month reporting period, MainStay's portfolio managers sought
to make the most of market conditions within the investment strategies and risk
parameters of their respective Funds. While individual markets and Fund results
may vary, our pursuit of competitive returns over full market cycles has never
changed.

The information that follows provides a closer look
at the securities, strategies and market conditions that affected your MainStay
Fund(s) during the six months ended April 30, 2010. Of course, past performance
is no guarantee of future results. Even in a rising market, we believe that
maintaining a long-term perspective can be valuable. At MainStay, we believe
that in all markets, broad diversification, gradual allocation adjustments and
regular portfolio reviews can help guide you toward your long-range financial
goals.

We thank you for choosing MainStay Funds, and we look forward to serving your
investment needs for many years to come.

Sincerely,


/s/ STEPHEN P. FISHER


Stephen P. Fisher

1. Performance tables and graphs do not reflect the deduction of taxes that a
   shareholder would pay on distributions or Fund-share redemptions. Total
   returns reflect maximum applicable sales charges explained in this paragraph,
   change in share price, and reinvestment of dividend and capital gain
   distributions. The graphs assume an initial investment of $25,000 for Class A
   shares and $10,000 for all other classes and reflect the deduction of all
   sales charges that would have applied for the period of investment. Class A
   shares generally have a $25,000 minimum initial investment with no minimum
   subsequent purchase amount. For investors that, in the aggregate, have assets
   of $100,000 or more invested in any share classes of any of the MainStay
   Funds, the minimum initial investment is $15,000. Investor Class and Class A
   shares are sold with a maximum initial sales charge of 5.50% and an annual
   12b-1 fee of 0.25%. Class C shares are sold with no initial sales charge, are
   subject to a contingent deferred sales charge ("CDSC") of 1.00% if redeemed
   within one year of purchase, and have an annual 12b-1 fee of 1.00%. Class I
   shares are sold with no initial sales charge or CDSC, have no annual 12b-1
   fee, and are generally available to corporate and institutional investors or
   individual investors with a minimum initial investment of $5 million. Class
   R1 shares are sold with no initial sales charge or CDSC and have no annual
   12b-1 fee. Class R2 shares are sold with no initial sales charge or CDSC and
   have an annual 12b-1 fee of 0.25%. Class R1 and R2 shares are available only
   through corporate-sponsored retirement programs, which include certain
   program requirements.

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY ICAP EQUITY FUND (UNAUDITED)
- --------------------------------------------------------------------------------

The example below is intended to describe the fees and expenses borne by
shareholders during the six-month period from November 1, 2009, to April 30,
2010, and the impact of those costs on your investment.

EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, exchange fees, and sales charges (loads) on
purchases (as applicable), and (2) ongoing costs, including management fees,
distribution and/or service (12b-1) fees, and other Fund expenses (as
applicable). This example is intended to help you understand your ongoing costs
(in dollars) of investing in the Fund and to compare these costs with the
ongoing costs of investing in other mutual funds. The example is based on an
investment of $1,000 made at the beginning of the six-month period and held for
the entire period from November 1, 2009, to April 30, 2010.

This example illustrates your Fund's ongoing costs in two ways:

- - ACTUAL EXPENSES
The second and third data columns in the table below provide information about
actual account values and actual expenses. You may use the information in these
columns, together with the amount you invested, to estimate the expenses that
you paid during the six-months ended April 30, 2010. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number under the heading entitled "Expenses Paid
During Period" to estimate the expenses you paid on your account during this
period.

- - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The fourth and fifth data columns in the table below provide information about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense ratio and an assumed rate of return of 5% per year before expenses,
which is not the Fund's actual return. The hypothetical account values and
expenses may not be used to estimate the actual ending account balances or
expenses you paid for the six-month period shown. You may use this information
to compare the ongoing costs of investing in the Fund with the ongoing costs of
investing in other Funds. To do so, compare this 5% hypothetical example with
the 5% hypothetical examples that appear in the shareholder reports of the other
Funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as
redemption fees, if applicable, exchange fees, or sales charges (loads).
Therefore, the fourth and fifth data columns of the table are useful in
comparing ongoing costs only and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.

   (1.57% for Investor Class, 1.18% for Class A, 2.31% for Class C, 0.90% for
   Class I, 1.03% for Class R1, 1.29% for Class R2 and 1.53% for Class R3)
   multiplied by the average account value over the period, divided by 365 and
   multiplied by 181 (to reflect the one-half year period). The table above
   represents the actual expenses incurred during the one-half year period.

Excluding all sales charges, MainStay ICAP Equity Fund returned 14.64% for
Investor Class shares, 14.84% for Class A shares and 14.19% for Class C shares
for the six months ended April 30, 2010. Over the same period, the Fund's Class
I shares returned 15.02%, Class R1 shares returned 14.95%, Class R2 shares
returned 14.81% and Class R3 shares returned 14.66%. Class A, Class I, Class R1,
Class R2 and Class R3 shares outperformed--and Investor Class and Class C shares
underperformed--the 14.65% return of the average Lipper(1) large-cap value fund
for the same time period. All share classes underperformed the 15.66% return of
the S&P 500(R) Index(2) for the six months ended April 30, 2010. The S&P 500(R)
Index is the Fund's broad-based securities-market index. See page 5 for Fund
returns with sales charges.

WHAT FACTORS ACCOUNTED FOR THE FUND'S PERFOR- MANCE RELATIVE TO THE S&P 500(R)
INDEX DURING
THE REPORTING PERIOD?

The Fund underperformed the S&P 500(R) Index during the reporting period
primarily because of weak stock selection in the consumer staples, health care
and financials sectors. These effects were partially offset by favorable stock
selection in the materials, energy and industrials sectors.

DURING THE REPORTING PERIOD, WHICH SECTORS MADE THE STRONGEST CONTRIBUTIONS TO
THE FUND'S RELATIVE PERFORMANCE AND WHICH SECTORS DETRACTED FROM PERFORMANCE?

Relative to the S&P 500(R) Index, the Fund's strongest-contributing sector
during the reporting period was industrials, followed by materials and energy.
The sectors that detracted the most from the Fund's performance relative to the
Index included health care, consumer staples and financials.

DURING THE REPORTING PERIOD, WHICH INDIVIDUAL STOCKS WERE POSITIVE CONTRIBUTORS
TO THE FUND'S ABSOLUTE PERFORMANCE AND WHICH STOCKS DETRACTED?

On an absolute basis, the stocks that made the strongest positive contributions
to the Fund's performance during the reporting period were home improvement
retailer Lowe's, diversified manufacturer Honeywell International and railroad
operator CSX. Each of these holdings benefited from a recovering economy and a
pickup in consumer and business activity.

Major detractors from the Fund's performance on an absolute basis included
pharmacy retailer and benefits manager CVS Caremark, diversified health care
company Sanofi-Aventis and brewer Molson Coors. Shares of CVS Caremark
underperformed the S&P 500(R) Index because of disappointing sales and because
gains from the integration of CVS and Caremark did not materialize as
anticipated. We sold the Fund's position in CVS Caremark during the reporting
period. Sanofi-Aventis and Molson Coors remained
in the Fund at the end of the reporting period, as
we continued to find these stocks attractive.

DID THE FUND MAKE ANY SIGNIFICANT PURCHASES OR SALES DURING THE REPORTING
PERIOD?

During a reporting period characterized by ongoing, if somewhat restrained,
economic recovery, the stock market was volatile but continued to rebound
overall. In this environment, we looked for stocks with attractive valuations
and specific catalysts that might trigger appreciation over a 12- to 18-month
time frame.

We added integrated oil firm ConocoPhillips to the Fund during the reporting
period. The investment reflected our belief that the stock was attractively
valued and that its management was focused on improving returns by divesting
underperforming assets, cutting costs and capital expenditures, and then using
free cash flow to reduce debt and repurchase shares. We also added insurance
carrier Aflac. We believed that the company's investment portfolio performance
and its sales in Japan would exceed expectations.

In addition to the sales already mentioned, we sold the Fund's position in
financial services provider Capital One Financial and semiconductor manufacturer
Intel. Each was sold when we found other stocks that we believed had greater
upside potential and were more attractive on a relative valuation basis.

HOW DID THE FUND'S SECTOR WEIGHTINGS CHANGE DURING THE REPORTING PERIOD?

During the reporting period, the Fund increased its sector exposure relative to
the S&P 500(R) Index in information technology and energy. With these increases,
the Fund shifted to an overweight posi-
tion in energy relative to the S&P 500(R) Index but remained underweight in
information technology.

Over the same period, the Fund decreased its allocations relative to the S&P
500(R) Index in consumer

2. See footnote on page 6 for more information on the S&P 500(R) Index.

10    MainStay ICAP Equity Fund



staples and financials. The reduced allocations made the Fund less overweight
relative to the S&P 500(R) Index in financials and more underweight relative to
the Index in consumer staples.

HOW WAS THE FUND POSITIONED AT THE END OF THE REPORTING PERIOD?

As of April 30, 2010, the Fund was overweight relative to the S&P 500(R) Index
in the energy and telecom-munication services sectors and underweight relative
to the Index in information technology and consumer staples. This positioning
reflected our views of the prospects for the economy and the relative
attractiveness of individual holdings in these sectors.

1. Performance tables and graphs do not reflect the deduction of taxes that a
   shareholder would pay on distributions or Fund-share redemptions. Total
   returns reflect maximum applicable sales charges explained in this paragraph,
   change in share price, and reinvestment of dividend and capital gain
   distributions. The graphs assume an initial investment of $25,000 for Class A
   shares and $10,000 for all other classes and reflect the deduction of all
   sales charges that would have applied for the period of investment. Class A
   shares generally have a $25,000 minimum initial investment with no minimum
   subsequent purchase amount. For investors that, in the aggregate, have assets
   of $100,000 or more invested in any share classes of any of the MainStay
   Funds, the minimum initial investment is $15,000. Investor Class and Class A
   shares are sold with a maximum initial sales charge of 5.50% and an annual
   12b-1 fee of 0.25%. Class C shares are sold with no initial sales charge, are
   subject to a contingent deferred sales charge ("CDSC") of 1.00% if redeemed
   within one year of purchase, and have an annual 12b-1 fee of 1.00%. Class I
   shares are sold with no initial sales charge or CDSC, have no annual 12b-1
   fee, and are generally available to corporate and institutional investors or
   individual investors with a minimum initial investment of $5 million. Class
   R1 shares are sold with no initial sales charge or CDSC and have no annual
   12b-1 fee. Class R2 shares are sold with no initial sales charge or CDSC and
   have an annual 12b-1 fee of 0.25%. Class R1 and R2 shares are available only
   through corporate-sponsored retirement programs, which include certain
   program requirements. Class R3 shares are sold with no initial sales charge
   or CDSC, have an annual 12b-1 fee of 0.50% and

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY ICAP SELECT EQUITY FUND
(UNAUDITED)
- --------------------------------------------------------------------------------

The example below is intended to describe the fees and expenses borne by
shareholders during the six-month period from November 1, 2009, to April 30,
2010, and the impact of those costs on your investment.

EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, exchange fees, and sales charges (loads) on
purchases (as applicable), and (2) ongoing costs, including management fees,
distribution and/or service (12b-1) fees, and other Fund expenses (as
applicable). This example is intended to help you understand your ongoing costs
(in dollars) of investing in the Fund and to compare these costs with the
ongoing costs of investing in other mutual funds. The example is based on an
investment of $1,000 made at the beginning of the six-month period and held for
the entire period from November 1, 2009, to April 30, 2010.

This example illustrates your Fund's ongoing costs in two ways:

- - ACTUAL EXPENSES
The second and third data columns in the table below provide information about
actual account values and actual expenses. You may use the information in these
columns, together with the amount you invested, to estimate the expenses that
you paid during the six-months ended April 30, 2010. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number under the heading entitled "Expenses Paid
During Period" to estimate the expenses you paid on your account during this
period.

- - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The fourth and fifth data columns in the table below provide information about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense ratio and an assumed rate of return of 5% per year before expenses,
which is not the Fund's actual return. The hypothetical account values and
expenses may not be used to estimate the actual ending account balances or
expenses you paid for the six-month period shown. You may use this information
to compare the ongoing costs of investing in the Fund with the ongoing costs of
investing in other Funds. To do so, compare this 5% hypothetical example with
the 5% hypothetical examples that appear in the shareholder reports of the other
Funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as
redemption fees, if applicable, exchange fees, or sales charges (loads).
Therefore, the fourth and fifth data columns of the table are useful in
comparing ongoing costs only and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.

1. Expenses are equal to the Fund's annualized expense ratio of each class
   (1.47% for Investor Class, 1.18% for Class A, 2.22% for Class B , 2.21% for
   Class C, 0.90% for Class I, 1.07% for Class R1, 1.32% for Class R2 and 1.57%
   for Class R3) multiplied by the average account value over the period,
   divided by 365 and multiplied by 181 days for Investor Class, Class A, Class
   C, Class I, Class R1, Class R2 and Class R3 (to reflect the one-half year
   period) and 169 days for Class B (to reflect the since-inception period).
2. Expenses paid during the period reflect ongoing costs for the period from
   inception through April 30, 2010. Had these shares been offered for the full
   six-month period ended April 30, 2010 and had the Fund provided a
   hypothetical 5% annualized return, expenses paid during the period would have
   been $11.08 and the ending account value would have been $1,013.80.
3. Class B shares began investment activity on November 13, 2009.

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

QUESTIONS ANSWERED BY PORTFOLIO MANAGERS JERROLD K. SENSER, CFA, AND THOMAS R.
WENZEL, CFA, OF INSTITUTIONAL CAPITAL LLC (ICAP), THE FUND'S SUBADVISOR.

HOW DID MAINSTAY ICAP SELECT EQUITY FUND PERFORM RELATIVE TO ITS PEERS AND ITS
BENCHMARK DURING THE SIX MONTHS ENDED APRIL 30, 2010?

Excluding all sales charges, MainStay ICAP Select Equity Fund returned 15.33%
for Investor Class shares, 15.50% for Class A shares and 14.92% for Class B and
Class C shares for the six months ended April 30, 2010. Over the same period,
the Fund's Class I shares returned 15.68%, Class R1 shares returned 15.58%,
Class R2 shares returned 15.41% and Class R3 shares returned 15.29%. All shares
classes outperformed the 14.65% return of the average Lipper(1) large-cap value
fund for the same time period. Class I shares outperformed--and all other share
classes underperformed--the 15.66% return of the S&P 500(R) Index(2) for the six
months ended April 30, 2010. The S&P 500(R) Index is the Fund's broad-based
securities-market index. See pages 22 and 23 for Fund returns with sales
charges.

WHAT FACTORS ACCOUNTED FOR THE FUND'S PERFOR-
MANCE RELATIVE TO THE S&P 500(R) INDEX DURING
THE REPORTING PERIOD?

Favorable stock selection in the energy and industrials sectors contributed
positively to Fund performance as did an overweight position relative to the S&P
500(R) Index in industrials. Stock selection in the consumer staples, health
care and financials sectors detracted from the Fund's performance relative to
the Index.

DURING THE REPORTING PERIOD, WHICH SECTORS MADE THE STRONGEST CONTRIBUTIONS TO
THE FUND'S RELATIVE PERFORMANCE AND WHICH SECTORS DETRACTED FROM PERFORMANCE?

Relative to the S&P 500(R) Index, the Fund's strongest-contributing sector
during the reporting period was industrials, followed by energy and materials.
The sectors that detracted the most from the Fund's performance relative to the
Index included health care, consumer staples and financials.

DURING THE REPORTING PERIOD, WHICH INDIVIDUAL STOCKS WERE STRONG CONTRIBUTORS TO
THE FUND'S ABSOLUTE PERFORMANCE AND WHICH STOCKS DETRACTED?

On an absolute basis, the holdings that made the strongest positive
contributions to the Fund's absolute performance during the reporting period
were home improvement retailer Lowe's, diversified manufacturer Honeywell
International and railroad operator CSX. Each of these three holdings benefited
from a recovering economy and a pickup in consumer and business activity.

Major detractors from performance on an absolute basis included pharmacy
retailer and benefits manager CVS Caremark, diversified health care company
Sanofi-Aventis and casualty insurer ACE. CVS Caremark performed poorly, as sales
disappointed. We sold the Fund's position in CVS Caremark during the reporting
period because the gains we expected from the integration of CVS and Caremark
failed to materialize. We eliminated the Fund's position in ACE, as our outlook
for anticipated pricing improvement and competitive advantages weakened and
other stocks looked more attractive. Sanofi-Aventis remained in the Fund at the
end of the reporting period, as we continued to find the stock attractive.

DID THE FUND MAKE ANY SIGNIFICANT PURCHASES OR SALES DURING THE REPORTING
PERIOD?

During a reporting period characterized by ongoing, if somewhat restrained,
economic recovery, the stock market was volatile but continued to rebound
overall. In this environment, we looked for stocks with attractive valuations
and specific catalysts that might trigger appreciation over a 12- to 18-month
time frame.

We added integrated oil firm ConocoPhillips to the Fund during the reporting
period. We felt that the stock was attractively valued and that its manage-ment
was focused on improving returns by divesting underperforming assets, cutting
costs and capital expenditures, and then using free cash flow to reduce debt and
repurchase shares. The Fund also added insurance carrier Aflac. We believed that
the com-
pany's investment portfolio performance and its sales in Japan would exceed
expectations.

In addition to the sales already mentioned, we sold the Fund's position in
financial services provider Capital One Financial and semiconductor manufacturer
Intel. Both stocks were sold when we found other stocks that we believed had
greater upside potential and were more attractive on a relative valuation basis.

WERE THERE ANY SIGNIFICANT SECTOR WEIGHTING CHANGES DURING THE REPORTING PERIOD?

During the reporting period, the Fund increased its sector weightings relative
to the S&P 500(R) Index in information technology and energy. With these

increases, the Fund shifted to an overweight position relative to the S&P 500(R)
Index in energy but remained underweight in information technology.

Over the same period, the Fund decreased its exposure to consumer staples and
financials. These changes made the Fund less overweight relative to the S&P
500(R) Index in financials and more underweight relative to the Index in
consumer staples.

HOW WAS THE FUND POSITIONED AT THE END OF THE REPORTING PERIOD?

As of April 30, 2010, the Fund was overweight relative to the S&P 500(R) Index
in the energy and industrials sectors and underweight relative to the Index in
information technology and consumer staples. This positioning reflected our view
of prospects for the economy and the relative attractiveness of individual
holdings in these sectors.

1. Performance tables and graphs do not reflect any deduction of taxes that a
   shareholder would pay on distributions or Fund-share redemptions. Total
   returns reflect maximum applicable sales charges explained in this paragraph,
   change in share price, and reinvestment of dividend and capital gain
   distributions. The graphs assume an initial investment of $25,000 for Class A
   shares and $10,000 for all other classes and reflect the deduction of all
   sales charges that would have applied for the period of investment. Class A
   shares generally have a $25,000 minimum initial investment with no minimum
   subsequent purchase amount. For investors that, in the aggregate, have assets
   of $100,000 or more invested in any share classes of any of the MainStay
   Funds, the minimum initial investment is $15,000. Investor Class and Class A
   shares are sold with a maximum initial sales charge of 5.50% and an annual
   12b-1 fee of 0.25%. Class C shares are sold with no initial sales charge, are
   subject to a contingent deferred sales charge ("CDSC") of 1.00% if redeemed
   within one year of purchase, and have an annual 12b-1 fee of 1.00%. Class I
   shares are sold with no initial sales charge or CDSC, have no annual 12b-1
   fee, and are generally available to corporate and institutional investors or
   individual investors with a minimum initial investment of $5 million.
   Performance figures reflect certain fee waivers and/or expense limitations,
   without which total returns would have been lower. For information on current
   fee waivers and/or expense limitations, please refer to the notes to the
   financial statements.

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY ICAP GLOBAL FUND (UNAUDITED)
- --------------------------------------------------------------------------------

The example below is intended to describe the fees and expenses borne by
shareholders during the six-month period from November 1, 2009, to April 30,
2010, and the impact of those costs on your investment.

EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, exchange fees, and sales charges (loads) on
purchases (as applicable), and (2) ongoing costs, including management fees,
distribution and/or service (12b-1) fees, and other Fund expenses (as
applicable). This example is intended to help you understand your ongoing costs
(in dollars) of investing in the Fund and to compare these costs with the
ongoing costs of investing in other mutual funds. The example is based on an
investment of $1,000 made at the beginning of the six-month period and held for
the entire period from November 1, 2009, to April 30, 2010.

This example illustrates your Fund's ongoing costs in two ways:

- - ACTUAL EXPENSES
The second and third data columns in the table below provide information about
actual account values and actual expenses. You may use the information in these
columns, together with the amount you invested, to estimate the expenses that
you paid during the six-months ended April 30, 2010. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number under the heading entitled "Expenses Paid
During Period" to estimate the expenses you paid on your account during this
period.

- - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The fourth and fifth data columns in the table below provide information about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense ratio and an assumed rate of return of 5% per year before expenses,
which is not the Fund's actual return. The hypothetical account values and
expenses may not be used to estimate the actual ending account balances or
expenses you paid for the six-month period shown. You may use this information
to compare the ongoing costs of investing in the Fund with the ongoing costs of
investing in other Funds. To do so, compare this 5% hypothetical example with
the 5% hypothetical examples that appear in the shareholder reports of the other
Funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as
redemption fees, if applicable, exchange fees, or sales charges (loads).
Therefore, the fourth and fifth data columns of the table are useful in
comparing ongoing costs only and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

QUESTIONS ANSWERED BY PORTFOLIO MANAGERS JERROLD K. SENSER, CFA, AND THOMAS R.
WENZEL, CFA, OF INSTITUTIONAL CAPITAL LLC (ICAP), THE FUND'S SUBADVISOR.

HOW DID MAINSTAY ICAP GLOBAL FUND PERFORM RELATIVE TO ITS PEERS AND ITS
BENCHMARK DURING THE SIX MONTHS ENDED APRIL 30, 2010?

Excluding all sales charges, MainStay ICAP Global Fund returned 8.10% for
Investor Class shares, 8.22% for Class A shares and 7.71% for Class C shares for
the six months ended April 30, 2010. Over the same period, the Fund's Class I
shares returned 8.29%. All share classes underperformed the 10.82% return of the
average Lipper(1) global multi-cap core fund and the 9.40% return of the MSCI
World Index(2) for the six months ended April 30, 2010. The MSCI World Index is
the Fund's broad-based securities-market index. See page 38 for Fund returns
with sales charges.

WHAT FACTORS AFFECTED THE FUND'S PERFORMANCE RELATIVE TO THE MSCI WORLD INDEX
DURING THE REPORTING PERIOD?

The Fund underperformed the MSCI World Index during the reporting period
primarily because of weak stock selection in the health care, utilities and
consumer discretionary sectors. The effects were partially offset by favorable
stock selection in the materials sector and by an overweight position relative
to the MSCI World Index in industrials.

DURING THE REPORTING PERIOD, WHICH FUND SECTORS MADE THE STRONGEST CONTRIBUTIONS
TO THE FUND'S RELATIVE PERFORMANCE AND WHICH SECTORS DETRACTED THE MOST?

During the reporting period, the sector that made
the strongest contribution to the Fund's performance relative to the MSCI World
Index was industrials, followed by energy and telecommunication services. The
sectors that detracted the most from the Fund's performance relative to the
Index were health care, utilities and financials.

DURING THE REPORTING PERIOD, WHICH INDIVIDUAL STOCKS MADE THE GREATEST POSITIVE
CONTRIBUTIONS TO THE FUND'S ABSOLUTE PERFORMANCE AND WHICH STOCKS DETRACTED?

On an absolute basis, the stocks that made the strongest positive contributions
to the Fund's performance during the reporting period included home improvement
retailer Lowe's, cable network and entertainment company Viacom and regional
bank BB&T. Lowe's benefited from the prospect that the housing market was
stabilizing and from a pickup in consumer spending. Viacom's stock rose on
improve-ment in the advertising market. Shares of BB&T strengthened as
conditions in the credit markets and the overall economy improved.

Major detractors from performance on an absolute basis included Spanish bank
Banco Santander, French bank Societe Generale and diversified health care
company Sanofi-Aventis. Banco Santander and Societe Generale were weak because
of rising concerns about Europe's sovereign debt during the reporting period. We
sold the Fund's position in Societe Generale during the reporting period when we
found other stocks to be more attractive. Banco Santander and Sanofi-Aventis
remained in the Fund at the end of the reporting period.

DID THE FUND MAKE ANY SIGNIFICANT PURCHASES OR SALES DURING THE REPORTING
PERIOD?

During a reporting period characterized by ongoing, if somewhat restrained,
economic recovery, the stock market was volatile but continued to rebound
overall. In this environment, we looked for stocks with attractive valuations
and specific catalysts that may trigger appreciation over a 12- to 18-month time
frame.

We added integrated oil firm ConocoPhillips to the Fund during the reporting
period. The investment reflected our belief that the stock was attractively
valued and that its management was focused on improving returns by divesting
underperforming assets, cutting costs and capital expenditures, and then using
free cash flow to reduce debt and repurchase shares. The Fund also added a
position in Bridgestone, the largest tire supplier in the world. At the time of
purchase, we believed pent-up demand would be unleashed in both the replacement
and original auto-equipment markets and might well result in improved sales
growth and profit margins for the company.

In addition to the sales already mentioned, we sold the Fund's position in
semiconductor manufacturer Intel when we found other stocks that we felt had
greater upside potential and were more attractive on a relative valuation basis.
We also sold the Fund's position in Saipem, an Italian company that specializes
in construction and drilling for the oil and gas industry worldwide, as it
reached our target price.

WERE THERE ANY SIGNIFICANT CHANGES IN THE FUND'S SECTOR WEIGHTINGS DURING THE
REPORTING PERIOD?

During the reporting period, the Fund increased its sector exposure relative to
the MSCI World Index in energy and materials. With these increases, the Fund

1. See footnote on page 39 for more information about Lipper Inc.
2. See footnote on page 38 for more information on the MSCI World Index.

42    MainStay ICAP Global Fund



shifted to an overweight position relative to the MSCI World Index in energy,
but remained underweight in materials.

Over the same period, we decreased the Fund's exposure to financials and
industrials. These changes reduced the Fund's overweight position in industrials
relative to the MSCI World Index and shifted the Fund's allocation to financials
to an underweight position relative to the Index.

HOW WAS THE FUND POSITIONED AT THE END OF THE REPORTING PERIOD?

As of April 30, 2010, the Fund was overweight relative to the MSCI World Index
in the industrials and consumer discretionary sectors and underweight relative
to the Index in consumer staples and information technology. This positioning
reflected our views of prospects for the economy and the relative attractiveness
of individual holdings in these sectors.

1. Performance tables and graphs do not reflect any deduction of taxes that a
   shareholder would pay on distributions or Fund-share redemptions. Total
   returns reflect maximum applicable sales charges explained in this paragraph,
   change in share price, and reinvestment of dividend and capital gain
   distributions. The graphs assume an initial investment of $25,000 for Class A
   shares and $10,000 for all other classes and reflect the deduction of all
   sales charges that would have applied for the period of investment. Class A
   shares generally have a $25,000 minimum initial investment with no minimum
   subsequent purchase amount. For investors that, in the aggregate, have assets
   of $100,000 or more invested in any share classes of any of the MainStay
   Funds, the minimum initial investment is $15,000. Investor Class and Class A
   shares are sold with a maximum initial sales charge of 5.50% and an annual
   12b-1 fee of 0.25%. Class C shares are sold with no initial sales charge, are
   subject to a contingent deferred sales charge ("CDSC") of 1.00% if redeemed
   within one year of purchase, and have an annual 12b-1 fee, of 1.00%. Class I
   shares are sold with no initial sales charge or CDSC, have no annual 12b-1
   fee, and are generally available to corporate and institutional investors or
   individual investors with a minimum initial investment of $5 million. Class
   R1 shares are sold with no initial sales charge or CDSC and have no annual
   12b-1 fee. Class R2 shares are sold with no initial sales charge or CDSC and
   have an annual 12b-1 fee of 0.25%. Class R1 and R2 shares are available only
   through corporate-sponsored retirement programs, which include certain
   program requirements.

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY ICAP INTERNATIONAL FUND
(UNAUDITED)
- --------------------------------------------------------------------------------

The example below is intended to describe the fees and expenses borne by
shareholders during the six-month period from November 1, 2009, to April 30,
2010, and the impact of those costs on your investment.

EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, exchange fees, and sales charges (loads) on
purchases (as applicable), and (2) ongoing costs, including management fees,
distribution and/or service (12b-1) fees, and other Fund expenses (as
applicable). This example is intended to help you understand your ongoing costs
(in dollars) of investing in the Fund and to compare these costs with the
ongoing costs of investing in other mutual funds. The example is based on an
investment of $1,000 made at the beginning of the six-month period and held for
the entire period from November 1, 2009, to April 30, 2010.

This example illustrates your Fund's ongoing costs in two ways:

- - ACTUAL EXPENSES
The second and third data columns in the table below provide information about
actual account values and actual expenses. You may use the information in these
columns, together with the amount you invested, to estimate the expenses that
you paid during the six-months ended April 30, 2010. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number under the heading entitled "Expenses Paid
During Period" to estimate the expenses you paid on your account during this
period.

- - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The fourth and fifth data columns in the table below provide information about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense ratio and an assumed rate of return of 5% per year before expenses,
which is not the Fund's actual return. The hypothetical account values and
expenses may not be used to estimate the actual ending account balances or
expenses you paid for the six-month period shown. You may use this information
to compare the ongoing costs of investing in the Fund with the ongoing costs of
investing in other Funds. To do so, compare this 5% hypothetical example with
the 5% hypothetical examples that appear in the shareholder reports of the other
Funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as
redemption fees, if applicable, exchange fees, or sales charges (loads).
Therefore, the fourth and fifth data columns of the table are useful in
comparing ongoing costs only and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.

   Class I, 1.15% for Class R1, 1.42% for Class R2 and 1.67% for Class R3)
   multiplied by the average account value over the period, divided by 365 and
   multiplied by 181 (to reflect the one-half year period). The table above
   represents the actual expenses incurred during the one-half year period.

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

QUESTIONS ANSWERED BY PORTFOLIO MANAGERS JERROLD K. SENSER, CFA, AND THOMAS R.
WENZEL, CFA, OF INSTITUTIONAL CAPITAL LLC (ICAP), THE FUND'S SUBADVISOR.

HOW DID MAINSTAY ICAP INTERNATIONAL FUND PERFORM RELATIVE TO ITS PEERS AND ITS
BENCHMARK DURING THE SIX MONTHS ENDED APRIL 30, 2010?

Excluding all sales charges, MainStay ICAP International Fund returned 0.96% for
Investor Class shares, 1.04% for Class A shares and 0.56% for Class C shares for
the six months ended April 30, 2010. Over the same period, the Fund's Class I
shares returned 1.17%, Class R1 shares returned 1.07%, Class R2 shares returned
0.96% and Class R3 shares returned 0.85%. All share classes underperformed the
2.98% return of the average Lipper(1) international large-cap value fund and the
2.48% return of the MSCI EAFE(R) Index(2) for the six months ended April 30,
2010. The MSCI EAFE(R) Index is the Fund's broad-based securities-market index.
See page 51 for Fund returns with sales charges.

WHAT FACTORS AFFECTED THE FUND'S PERFORMANCE RELATIVE TO THE MSCI EAFE(R) INDEX
DURING THE REPORTING PERIOD?

The Fund underperformed the MSCI EAFE(R) Index primarily because of weak stock
selection in the financials, utilities and consumer discretionary sectors. The
effects were partially offset by favorable stock selection in the
telecommunication services and materials sectors. The Fund's relative
performance also benefited from an overweight position in industrials.

DURING THE REPORTING PERIOD, WHICH FUND SECTORS MADE THE STRONGEST CONTRIBUTIONS
TO THE FUND'S RELATIVE PERFORMANCE AND WHICH SECTORS DETRACTED THE MOST?

During the reporting period, the sector that made the strongest contribution to
the Fund's performance relative to the MSCI EAFE(R) Index was industrials,
followed by telecommunication services and materials. The sectors that detracted
the most from the Fund's relative performance were utilities, health care and
consumer discretionary.

DURING THE REPORTING PERIOD, WHICH INDIVIDUAL STOCKS MADE THE GREATEST POSITIVE
CONTRIBUTIONS TO THE FUND'S PERFORMANCE AND WHICH STOCKS DETRACTED?

On an absolute basis, the stocks that made the strongest positive contributions
to the Fund's performance during the reporting period were Vallourec, a French
manufacturer of steel tubing for the oil and gas industry; Barrick Gold, a
Canadian gold mining firm; and Hoya, a Japanese optical glass manufacturer.
Vallourec's shares rose as the company benefited from high oil prices and
renewed exploration and production. Barrick Gold benefited from higher gold
prices. Hoya performed well as a recovering economy increased demand in the
company's core markets. Barrick Gold and Hoya remained in the Fund as of April
30, 2010, but we sold Vallourec as it reached our target price.

Major detractors from performance on an absolute basis included Spanish bank
Banco Santander, French bank Societe Generale and Portuguese electric utility
Energias de Portugal. Each was weak, as concerns increased during the reporting
period about Europe's sovereign debt. Banco Santander and Energias de Portugal
remained in the Fund at the end of the reporting period, but we sold the Fund's
position in Societe Generale because we found other stocks to be more
attractive.

DID THE FUND MAKE ANY SIGNIFICANT PURCHASES OR SALES DURING THE REPORTING
PERIOD?

During a reporting period characterized by ongoing, if somewhat restrained,
economic recovery, the stock market was volatile but continued to rebound
overall. In this environment, we looked for stocks with both attractive
valuations and specific catalysts that may trigger appreciation over a 12- to
18-month time frame.

We added a position in Bridgestone, the world's largest tire supplier, to the
Fund during the reporting period. At the time of purchase, we believed pent-up
demand would be unleashed in both the replacement and original auto-equipment
markets and might well result in improved sales growth and profit margins for
the company. The Fund also added Japanese insurer Tokio Marine. We felt that
stronger pricing within the insurance industry would drive better underwriting
profitability for the company and lead to improvement in its share price.

In addition to the sales already mentioned, we sold the Fund's position in
Saipem, an Italian company that specializes in construction and drilling for the
oil and gas industry worldwide. We also sold the Fund's holding in Pernod-
Ricard, a global leader in the wine and spirits industry. Saipem and Pernod-
Richard were sold as they reached their respective price targets.

WERE THERE ANY SIGNIFICANT CHANGES IN THE FUND'S SECTOR WEIGHTINGS DURING THE
REPORTING PERIOD?

During the reporting period, the Fund increased its exposure relative to the
MSCI EAFE(R) Index in the materials and health care sectors. With these

increases, the Fund shifted to a slightly overweight position in materials
relative to the MSCI EAFE(R) Index and added to the Fund's already overweight
allocation in health care relative to the Index.

Over the same period, we decreased the Fund's exposure to consumer discretionary
and financials. These reductions made the Fund less overweight relative to the
MSCI EAFE(R) Index in consumer discretionary and more underweight relative to
the Index in financials.

HOW WAS THE FUND POSITIONED AT THE END OF THE REPORTING PERIOD?

As of April 30, 2010, the Fund was overweight relative to the MSCI EAFE(R) Index
in the industrials and consumer discretionary sectors and underweight relative
to the Index in consumer staples and financials. This positioning reflected our
views of the prospects for the economy and the relative attractiveness of
individual holdings in these sectors.

NOTES TO FINANCIAL STATEMENTS UNAUDITED

NOTE 1--ORGANIZATION AND BUSINESS:

MainStay Funds Trust (the "Trust") is organized as a Delaware Statutory Trust
and is governed by a Declaration of Trust dated April 8, 2009. The Trust is
registered under the Investment Company Act of 1940, as amended (the "1940 Act")
as an open-end management investment company, and is comprised of twenty-nine
funds (collectively referred to as the ''Funds" and each individually, referred
to as a "Fund"). These financial statements and notes relate to the MainStay
ICAP Equity Fund, MainStay ICAP Global Fund, MainStay ICAP International Fund
and MainStay ICAP Select Equity Fund (collectively, referred to as the "ICAP
Funds" and each individually referred to as an "ICAP Fund"). Each is a
diversified fund. Each ICAP Fund is the successor of a series of ICAP Funds,
Inc. with the same name (each a "Predecessor Fund"). The reorganizations of the
Predecessor Funds with and into the respective ICAP Funds, which were not
subject to shareholder approval under applicable law, occurred on February 26,
2010. All information regarding and references to periods prior to the
commencement of operations of each ICAP Fund relate to the respective
Predecessor Fund.

The ICAP Funds through each Predecessor Fund, commenced operations on the dates
indicated below:

The MainStay ICAP International Fund and MainStay ICAP Equity Fund offer seven
classes of shares: Investor Class, Class A, Class C, Class I, Class R1, Class R2
and Class R3 shares. Each of these share classes, other than Investor Class and
Class I shares, commenced operations on August 31, 2006. Class I shares
commenced operations (under a former designation) on December 31, 1994 for
MainStay ICAP Equity Fund and on December 31, 1997 for MainStay ICAP
International Fund. Investor Class shares commenced operations on April 29, 2008
for MainStay ICAP Equity Fund and MainStay ICAP International Fund. The MainStay
ICAP Global Fund offers four classes of shares: Investor Class, Class A, Class C
and Class I shares. All share classes of the MainStay ICAP Global Fund commenced
operations on April 30, 2008. The MainStay ICAP Select Equity Fund offers eight
classes of shares: Investor Class, Class A, Class B, Class C, Class I, Class R1,
Class R2 and Class R3 shares. Each of these share classes, other than Investor
Class and Class I shares, commenced operations on August 31, 2006. Investor
Class shares commenced operations on April, 29, 2008, and Class I shares
commenced operations on December 31, 1997 (under a former designation). Class B
shares for MainStay ICAP Select Equity Fund commenced operations on November 13,
2009.

Investor Class and Class A shares are offered at net asset value ("NAV") per
share plus an initial sales charge. No sales charge applies on investments of $1
million or more (and certain other qualified purchases) in Investor Class and
Class A shares, but a contingent deferred sales charge is imposed on certain
redemptions of such shares within one year of the date of purchase. Class B
shares and Class C shares are offered at NAV without an initial sales charge,
although a declining contingent deferred sales charge may be imposed on
redemptions made within six years of purchase of Class B shares and a 1.00%
contingent deferred sales charge may be imposed on redemptions made within one
year of purchase of Class C shares. Class I, Class R1, Class R2 and Class R3
shares are offered at NAV without imposition of a front-end sales charge or a
contingent deferred sales charge. Depending upon eligibility, Class B shares
convert to either Investor Class or Class A shares eight years after the date
they were purchased. Additionally, depending upon eligibility, Investor Class
shares may convert to Class A shares and Class A shares may convert to Investor
Class shares. Each class of shares have the same voting (except for issues that
relate solely to one class), dividend, liquidation and other rights, and the
same terms and conditions, except that the classes are subject to different
distribution and/or service fee rates. Investor Class, Class A, Class C, Class
R2 and Class R3 shares each bear distribution and/or service fee payments under
distribution and service plans pursuant to Rule 12b-1 under the 1940 Act. Class
R1, Class R2 and Class R3 shares are authorized to pay a shareholder service fee
to New York Life Investment Management LLC, its affiliates, or third-party
service providers, as compensation for services rendered to shareholders of
Class R1, Class R2 or Class R3 shares.

The investment objective for each of the ICAP Funds is as follows:

The MAINSTAY ICAP EQUITY FUND seeks a superior total return with only a moderate
degree of risk.

The MAINSTAY ICAP SELECT EQUITY FUND seeks a superior total return.

The MAINSTAY ICAP GLOBAL FUND seeks a superior total return.

The MAINSTAY ICAP INTERNATIONAL FUND seeks a superior total return with income
as a secondary objective.

NOTE 2--SIGNIFICANT ACCOUNTING POLICIES:

The ICAP Funds prepare their financial statements in accordance with accounting
principles generally accepted in the United States of America ("GAAP") and
follow the significant accounting policies described below.

(A) SECURITIES VALUATION.  Equity securities are valued at the latest quoted
sales prices as of the close of regular trading on the New York Stock Exchange
("Exchange") (generally 4:00 p.m. Eastern time) on each day the ICAP


68    MainStay ICAP Funds



Funds are open for business ("valuation date"). Securities that are not traded
on the valuation date are valued at the mean of the latest quoted bid and asked
prices. Prices normally are taken from the principal market in which each
security trades. Investments in other mutual funds are valued at their NAVs as
of the close of the Exchange on the valuation date.

Temporary cash investments acquired over 60 days prior to maturity are valued
using the latest bid prices or using valuations based on a matrix system (which
considers such factors as security prices, yields, maturities, and ratings),
both as furnished by independent pricing services. Other temporary cash
investments which mature in 60 days or less ("short-term investments") are
valued at amortized cost. The amortized cost method involves valuing a security
at its cost on the date of purchase and thereafter assuming a constant
amortization to maturity of the difference between the principal amount due at
maturity and cost. Investments in money market funds are valued daily at their
NAV.

Certain events may occur between the time that foreign markets close, on which
securities held by certain of the ICAP Funds principally trade, and the time at
which the ICAP Funds' NAVs are calculated. These events may include, but are not
limited to, situations relating to a single issue in a market sector,
significant fluctuations in U.S. or foreign markets, natural disasters, armed
conflicts, governmental actions or other developments not tied directly to the
securities markets. Should the Manager or Subadvisor, as defined in Note 3(A),
conclude that such events may have affected the accuracy of the last price
reported on the local foreign market, the Manager or Subadvisor may, pursuant to
procedures adopted by the ICAP Funds' Board, adjust the value of the local price
to reflect the impact on the price of such securities as a result of such
events. Additionally, international equity securities are also fair valued
whenever the movement of a particular index exceeds certain thresholds. In such
cases, the securities are fair valued by applying factors provided by a third
party vendor in accordance with the ICAP Funds' policies and procedures. At
April 30, 2010, certain foreign equity securities held by the ICAP Funds were
fair valued.

Securities for which market quotations are not readily available are valued by
methods deemed in good faith by the ICAP Funds' Board to represent fair value.
Equity and non-equity securities which may be valued in this manner include, but
are not limited to: (i) a security the trading for which has been halted or
suspended; (ii) a debt security that has recently gone into default and for
which there is not a current market quotation; (iii) a security of an issuer
that has entered into a restructuring; (iv) a security that has been de-listed
from a national exchange; (v) a security the market price of which is not
available from an independent pricing source or, if so provided, does not, in
the opinion of the ICAP Fund's Manager or Subadvisor, as defined in Note 3(A),
reflect the security's market value; and (vi) a security where the trading on
that security's principal market is temporarily closed at a time when, under
normal conditions, it would be open. At April 30, 2010, the ICAP Funds did not
hold securities that were valued in such a manner.

"Fair value" is defined as the price that the ICAP Fund would receive upon
selling an investment in an orderly transaction to an independent buyer in the
principal or most advantageous market of the investment. Fair value measurements
are determined within a frame work that has established a three-tier hierarchy
which maximizes the use of observable market data and minimizes the use of
unobservable inputs to establish classification of fair value measurements for
disclosure purposes. "Inputs" refer broadly to the assumptions that market
participants would use in pricing the asset or liability, including assumptions
about risk, such as the risk inherent in a particular valuation technique used
to measure fair value using a pricing model and/or the risk inherent in the
inputs for the valuation technique. Inputs may be observable or unobservable.
Observable inputs are inputs that reflect the assumptions market participants
would use in pricing the asset or liability based on market data obtained from
sources independent of the reporting entity. Unobservable inputs are inputs that
reflect the reporting entity's own assumptions about the assumptions market
participants would use in pricing the asset or liability developed based on the
information available in the circumstances. The inputs or methodology used for
valuing securities may not be an indication of the risks associated with
investing in those securities. The three-tier hierarchy of inputs is summarized
in the three broad Levels listed below.

- - Level 1--quoted prices in active markets for identical investments

- - Level 2--other significant observable inputs (including quoted prices for
  similar investments in active markets, interest rates and yield curves,
  prepayment speeds, credit risks, etc.)

- - Level 3--significant unobservable inputs (including the ICAP Fund's own
  assumptions about the assumptions that market participants would use in
  determining the fair value of investments)

The aggregate value by input level, as of April 30, 2010, for each ICAP Fund's
investments is included at the end of each ICAP Fund's Portfolio of Investments.

The valuation techniques used by the ICAP Funds to measure fair value during the
six-month period ended April 30, 2010 maximized the use of observable inputs and
minimized the use of unobservable inputs. The ICAP Funds may have utilized some
of the following fair value techniques: multi-dimensional relational pricing
models, option adjusted spread pricing and estimating the price that would have
prevailed in a liquid market for an international equity security given
information available at the time of

                                                   mainstayinvestments.com    69



NOTES TO FINANCIAL STATEMENTS UNAUDITED (CONTINUED)


evaluation, when there are significant events after the close of local foreign
markets. For the six-month period ended April 30, 2010, there have been no
changes to the fair value methodologies.

(B) FEDERAL INCOME TAXES.  Each of the ICAP Funds is treated as a separate
entity for federal income tax purposes. The ICAP Funds' policy is to comply with
the requirements of the Internal Revenue Code of 1986, as amended (the "Internal
Revenue Code") applicable to regulated investment companies and to distribute
all of the taxable income to the shareholders of each ICAP Fund within the
allowable time limits. Therefore, no federal income tax provision is required.

Investment income received by the ICAP Funds from foreign sources may be subject
to foreign income taxes. These foreign income taxes are generally withheld at
the source.

Management evaluates its tax positions to determine if the tax positions taken
meet the minimum recognition threshold in connection with accounting for
uncertainties in income tax positions taken or expected to be taken for the
purposes of measuring and recognizing tax liabilities in the financial
statements. Recognition of tax benefits of an uncertain tax position is required
only when the position is "more likely than not" to be sustained assuming
examination by taxing authorities. Management has analyzed the ICAP Funds' tax
positions taken on federal income tax returns for all open tax years (current
and prior three tax years), and has concluded that no provision for federal
income tax is required in the ICAP Funds' financial statements. The ICAP Funds'
federal and state income and federal excise tax returns for tax years for which
the applicable statutes of limitations have not expired are subject to
examination by the Internal Revenue Service and state departments of revenue.

(C) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS.  Dividends and distributions
are recorded on the ex-dividend date. Dividends from net investment income are
declared and paid quarterly for the MainStay ICAP Equity Fund and MainStay ICAP
Select Equity Fund, to the extent that income is available. For the MainStay
ICAP Global Fund and MainStay ICAP International Fund, income dividends are
normally paid less frequently, typically on a semi-annual or annual basis.
Distributions from net realized capital gains, if any, are declared and paid
annually. Unless the shareholder elects otherwise, all dividends and
distributions are reinvested in the same class of shares of the respective ICAP
Fund, at NAV. Dividends and distributions to shareholders are determined in
accordance with federal income tax regulations and may differ from GAAP.

(D) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  The ICAP Funds record security
transactions on the trade date. Realized gains and losses on security
transactions are determined using the identified cost method. Dividend income is
recognized on the ex-dividend date and interest income is accrued as earned
using the effective interest rate method. Discounts and premiums on securities
purchased, other than short-term investments, for the ICAP Funds are accreted
and amortized, respectively, on the effective interest rate method over the life
of the respective securities or, in the case of a callable security, over the
period to the first date of call. Discounts and premiums on short-term
investments are accreted and amortized, respectively, on the straight line
method.

Investment income and realized and unrealized gains and losses on investments of
the ICAP Funds are allocated to separate classes of shares pro rata based upon
their relative net assets on the date the income is earned or realized and
unrealized gains and losses are incurred.

(E) EXPENSES.  Expenses of the Trust are allocated to the individual ICAP Funds
in proportion to the net assets of the respective ICAP Funds when the expenses
are incurred, except where direct allocations of expenses can be made. Expenses
(other than transfer agent expenses and fees incurred under the shareholder
services plans and the distribution plans further discussed in Note 3(B)) are
allocated to separate classes of shares pro rata based upon their relative NAV
on the date the expenses are incurred. The expenses borne by each ICAP Fund,
including those of related parties to the ICAP Funds, are shown in the Statement
of Operations.

(F) USE OF ESTIMATES.  In preparing financial statements in conformity with
GAAP, management makes estimates and assumptions that affect the reported
amounts and disclosures in the financial statements. Actual results could differ
from those estimates.

(G) RECLASSIFICATION.  Certain prior year amounts have been reclassified to
conform with the current year presentation.

(H) REPURCHASE AGREEMENTS.  The ICAP Funds may enter into repurchase agreements
to earn income. The ICAP Funds may enter into repurchase agreements only with
financial institutions that are deemed by the Manager or Subadvisor to be
creditworthy, pursuant to guidelines established by the ICAP Funds' Board.
Repurchase agreements are considered under the 1940 Act to be collateralized
loans by a Fund to the seller secured by the securities transferred to the Fund.

When the ICAP Funds invest in repurchase agreements, the ICAP Funds' custodian
takes possession of the collateral pledged for investments in such repurchase
agreements. The underlying collateral is valued daily on a mark-to-market basis
to determine that the value, including accrued interest, exceeds the repurchase
price. In the event of the seller's default of the obligation to repurchase, the
ICAP Funds have the right to liquidate the collateral and apply the proceeds in
satisfaction of the obligation. Under certain circumstances, in the event of
default or bankruptcy by the


70    MainStay ICAP Funds



other party to the agreement, realization and/or retention of the collateral may
be subject to legal proceedings and possible realized loss to the respective
ICAP Fund.

(I) FOREIGN CURRENCY TRANSACTIONS.  The books and records of the ICAP Funds are
kept in U.S. dollars. Prices of securities denominated in foreign currency
amounts are translated into U.S. dollars at the mean between the buying and
selling exchange rates last quoted by any major U.S. bank at the following
dates:

(i)   market value of investment securities, other assets and liabilities--at
      the valuation date, and

(ii)  purchases and sales of investment securities, income and expenses--at the
      date of such transactions.

The assets and liabilities that are denominated in foreign currency amounts are
presented at the exchange rates and market values at the close of the period.
The realized and unrealized changes in net assets arising from fluctuations in
exchange rates and market prices of securities are not separately presented.

Net realized gain (loss) on foreign currency transactions represents net gains
and losses on foreign currency forward contracts, net currency gains or losses
realized as a result of differences between the amounts of securities sale
proceeds or purchase cost, dividends, interest and withholding taxes as recorded
on the ICAP Funds' books, and the U.S. dollar equivalent amount actually
received or paid. Net currency gains or losses from valuing such foreign
currency denominated assets and liabilities, other than investments at valuation
date exchange rates, are reflected in unrealized foreign exchange gains or
losses. (See Note 5.)

(J) SECURITIES LENDING.  In order to realize additional income, the ICAP Funds
may engage in securities lending, subject to the limitations set forth in the
1940 Act, and relevant guidance by the staff of the Securities and Exchange
Commission. In the event the ICAP Funds do engage in securities lending, the
ICAP Funds will lend through their custodian, State Street Bank and Trust
Company ("State Street"). State Street will manage the ICAP Funds' cash
collateral in accordance with the Lending Agreement between the ICAP Funds and
State Street, and indemnify the ICAP Funds' portfolios against counterparty
risk. The loans will be collateralized by cash or securities at least equal at
all times to the market value of the securities loaned. Collateral will consist
of U.S. Government securities, cash equivalents or irrevocable letters of
credit. The ICAP Funds may bear the risk of delay in recovery of, or loss of
rights in, the securities loaned should the borrower of the securities
experience financial difficulty. The ICAP Funds may also record realized gain or
loss on securities deemed sold due to a borrower's inability to return
securities on loan. The ICAP Funds will receive compensation for lending their
securities in the form of fees or retain a portion of interest on the investment
of any cash received as collateral. The ICAP Funds also will continue to receive
interest and dividends on the securities loaned and any gain or loss in the
market price of the securities loaned that may occur during the term of the loan
will be for the account of the ICAP Funds.

Although the ICAP Funds and New York Life Investments (as defined in Note 3(A))
have temporarily suspended securities lending, the ICAP Funds and New York Life
Investments reserve the right to reinstitute lending when deemed appropriate.
The ICAP Funds had no portfolio securities on loan as of April 30, 2010.

(K) RIGHTS/WARRANTS.  A right is a certificate that permits the holder to
purchase a certain number of shares, or a fractional share, of a new stock from
the issuer at a specific price. A warrant is an instrument that entitles the
holder to buy an equity security at a specific price for a specific period of
time. The ICAP Funds enter into rights and warrants when securities are acquired
through a corporate action. With respect to warrants in international markets,
the securities are only purchased when the underlying security can not be
purchased due to the many restrictions an industry and/or country might place on
foreign investors. These investments can provide a greater potential for profit
or loss than an equivalent investment in the underlying security. Prices of
these investments do not necessarily move in tandem with the prices of the
underlying securities, and are speculative investments.

There is risk involved in the purchase of rights and warrants in that these
investments are speculative investments. The ICAP Funds could also lose the
entire value of the investment in warrants if the warrant is not exercised by
the date of its expiration. The ICAP Funds invest in warrants only if received
as part of a corporate action. The securities are sold as soon as the
opportunity becomes available. The ICAP Funds are exposed to risk until each
sale is completed.

(L) REDEMPTION FEE.  Prior to April 1, 2010, the MainStay ICAP Global Fund and
MainStay ICAP International Fund imposed a 2.00% redemption fee on redemptions
(including exchanges) of ICAP Fund shares made within 60 days of their date of
purchase for any class. The redemption fee was designed to offset brokerage
commissions and other costs associated with short-term trading and was not
assessed on the shares acquired through the reinvestment of dividends or
distributions paid by the ICAP Fund. The redemption fees are included in the
Statement of Changes in Net Assets and are retained by these ICAP Funds.

(M) CONCENTRATION OF RISK.  The ICAP Funds may invest in foreign securities,
which carry certain risks that are in addition to the usual risks inherent in
domestic instruments. These risks include those resulting from currency
fluctuations, future adverse political or economic developments and possible
imposition of currency exchange blockages or other foreign governmental laws or
restrictions.

NOTES TO FINANCIAL STATEMENTS UNAUDITED (CONTINUED)


These risks are likely to be greater in emerging markets than in developed
markets.

(N) OFFERING COSTS.  Costs incurred by the MainStay ICAP Global Fund in
connection with the commencement of the MainStay ICAP Global Fund's operations
were amortized on a straight line basis over the first twelve months of the
MainStay ICAP Global Fund's operations.

(O) INDEMNIFICATIONS.  Under the Trust's organizational documents, its officers
and trustees are indemnified against certain liabilities that may arise out of
performance of their duties to the Trust. Additionally, in the normal course of
business, the ICAP Funds enter into contracts with third-party service providers
that contain a variety of representations and warranties and which provide
general indemnifications. The ICAP Funds' maximum exposure under these
arrangements is unknown, as this would involve future claims that may be made
against the ICAP Funds that have not yet occurred. Based on experience,
management is of the view that the risk of loss in connection with these
potential indemnification obligations is remote. However, there can be no
assurance that material liabilities related to such obligations will not arise
in the future, which could adversely impact the ICAP Funds.

(P) QUANTITATIVE DISCLOSURE OF DERIVATIVE HOLDINGS.  The following tables show
additional disclosures about the ICAP Funds' derivative and hedging activities,
including how such activities are accounted for and their effect on the ICAP
Funds' financial positions, performance and cash flows. These derivatives are
not accounted for as hedging instruments.

(E) SMALL ACCOUNT FEE.  Shareholders with small accounts adversely impact the
cost of providing transfer agency services. In an effort to reduce total
transfer agency expenses, the ICAP Funds have implemented a small account fee on
certain types of accounts. Certain shareholders with an account balance of less
than $1,000 are charged an annual per account fee of $20 (assessed semi-
annually). These fees are included in transfer agent fees shown on the Statement
of Operations.

(a) In addition to any automatic conversion features
    described above in Note 1 with respect to Investor
    Class, Class A and B shares, you generally may also
    elect to convert your shares on a voluntary basis
    into another share class of the same ICAP Fund for
    which you are eligible. However, the following
    limitations apply:
</Table>


    - Investor Class and Class A shares that remain subject to a CDSC are
      ineligible for a voluntary conversion; and

    - All Class B and C shares are ineligible for a voluntary conversion.

These limitations do not impact any automatic conversion features described in
Note 1 with respect to Investor Class, Class A and B shares.

An investor or an investor's financial intermediary may contact the ICAP Funds
to request a voluntary conversion between shares classes of the same ICAP Fund.
You may be required to provide sufficient information to establish eligibility
to convert to the new share class. All permissible conversions will be made on
the basis of the relevant NAVs of the two classes without the imposition of any
sales load, fee or other charge. If you fail to remain eligible for the new
share class, you may automatically be converted back to your original share
class, or into another share class, if appropriate.

NOTE 10--FUND ACQUISITIONS:

At a meeting held on June 23, 2009, the Board approved a plan of reorganization
whereby the MainStay ICAP Select Equity Fund would acquire the assets, including
the investments, and assume the liabilities of MainStay Value Fund, a series of
The MainStay Funds. Shareholders of the MainStay Value Fund approved this
reorganization on November 5, 2009, which was completed on November 12, 2009.
The aggregate net assets of the MainStay ICAP Select Equity Fund immediately
before the acquisition were $1,835,281,477 and the combined net assets after the
acquisition were $2,189,364,629.

The acquisition was accomplished by a tax-free exchange of the following:

In exchange for the MainStay Value Fund shares and net assets, the MainStay ICAP

shares; 1,913,939 Class B shares; 181,117 Class C shares; 472,783 Class I
shares; 36 Class R1 shares and 1,563 Class R2 shares.

MainStay Value Fund's net assets at the acquisition date were as follows, which
include the following amounts of capital stock, unrealized appreciation,
accumulated net realized loss and undistributed net investment loss:

Net increase in net assets
  resulting from operations          $346,793,133
- -------------------------------------------------

</Table>


Because the combined investment portfolios have been managed as a single
integrated portfolio since the acquisition was completed, it is not practicable
to separate the amounts of revenue and earnings of the MainStay Value Fund that
have been included in the MainStay ICAP Select Equity Fund's Statement of
Operations since October 31, 2009.

In December 2007, the Financial Accounting Standards Board issued Accounting
Standards Codification (ASC) 805 (formerly FAS 141R Business Combinations),
which requires the following disclosures by the acquirer, among other things,
when a transaction or other event meets the definition of a business
combination:

- - The identification of the acquiree

- - Recognizing and measuring identifiable assets acquired and liabilities
  assumed, at the acquisition date, generally at their fair values

- - Disclosure, by the acquirer, of information that enables users of its
  financial statements to evaluate the nature and financial effect of a business
  combination that occurs during the current reporting period

ASC 805 requires prospective application to business combinations for which the
acquisition date occurs in an annual reporting period beginning on or after
December 15, 2008.

In accordance with ASC 805, for financial reporting purposes, assets received
and shares issued by the MainStay ICAP Select Equity Fund were recorded at fair
value; however, the cost basis of the investments received from MainStay Value
Fund was carried forward to align ongoing reporting of the MainStay ICAP Select
Equity Fund's realized and unrealized gains and losses with amounts
distributable to shareholders for tax purposes.

ASC 805 requires disclosure in this semi-annual report, and in the Fund's annual
report as of October 31, 2010, of the MainStay ICAP Select Equity Fund's pro-
forma results of operations, including net investment income, net gain (loss) on
investments and net increase (decrease) in net assets resulting from operations,
assuming the acquisition had been completed on November 1, 2009, the beginning
of the annual reporting period of the MainStay ICAP Select Equity Fund, through
the end of the applicable reporting period.

ASC 805 also requires the MainStay ICAP Select Equity Fund to report, if
practicable, the amounts of revenue and earnings of the acquiree since the
acquisition date included in the combined entity's income statement for the
reporting period. Because the combined investment portfolios have been managed
as a single integrated portfolio since the acquisition was completed, it is not
practicable to separate the amounts of revenue and earnings of the MainStay
Value Fund that will be included in the MainStay ICAP Select Equity Fund's
Statement of Operations since November 12, 2009.

Also at the meeting held on June 23, 2009, the Board approved a plan of
reorganization whereby the MainStay ICAP Select Equity Fund would acquire the
assets, including the investments, and assume the liabilities of MainStay Mid
Cap Value Fund, a series of The MainStay Funds. Shareholders of the MainStay Mid
Cap Value Fund approved this reorganization on November 16, 2009, which was
completed on November 24, 2009. The aggregate net assets of the MainStay ICAP
Select Equity Fund immediately before the acquisition were $2,229,459,923 and
the combined net assets after the acquisition were $2,381,725,187.

The acquisition was accomplished by a tax-free exchange of the following:

NOTE 11--NEW ACCOUNTING PRONOUNCEMENT:

In January 2010, the Financial Accounting Standards Board ("FASB") issued
Accounting Standards Update ("ASU") No. 2010-06 "Improving Disclosures about
Fair Value Measurements". ASU 2010-06 requires reporting entities to make new
disclosures about amount and reasons for significant transfers in and out of
Level 1 and Level 2 fair value measurements and input and valuation techniques
used to measure fair value for both recurring and nonrecurring fair value
measurements that fall in either Level 2 or Level 3, and information on
purchased, sales, issuances, and settlements in the roll forward of activity in
Level 3 fair value measures. The new and revised disclosure requirements are
effective for interim and annual reporting periods beginning after December 15,
2009 except for the disclosures about purchased, sales, issuances, and
settlements in the roll forward of activity in Level 3 fair value measures,
which are effective for fiscal years beginning after December 15, 2010. As of
April 30, 2010, the ICAP Funds have adopted ASU 2010-06. The adoption of ASU
2010-06 has not impacted the amounts reported in the ICAP Funds' financial
statements; however, there are additional disclosures in each of the ICAP Funds'
Portfolio of Investments.

NOTE 12--SUBSEQUENT EVENTS:

In connection with the preparation of the financial statements of the Fund as of
and for the fiscal six-month period ended April 30, 2010, events and
transactions subsequent to April 30, 2010 through the date the financial
statements were issued have been evaluated by the Fund's management for possible
adjustment and/or disclosure. No subsequent events requiring financial statement
adjustment or disclosure have been identified.

        MESSAGE FROM THE PRESIDENT AND SEMIANNUAL REPORT

        Unaudited - April 30, 2010



MESSAGE FROM THE PRESIDENT

During the six months ended April 30, 2010, stock and bond markets generally
advanced, despite some volatility in January and February. Domestic small-cap
stocks were particularly strong, and U.S. stocks at all capitalization levels
provided double digit returns. Value stocks outpaced growth stocks for companies
of all sizes during the reporting period.

International stocks provided positive returns overall, but results varied
widely by country. Concerns about Greece's ability to meet its debt obligations
led many investors to abandon their holdings in Greece and question their
investments in several peripheral European nations where perceived risk had
increased. For the six-month reporting period, equities in the Far East
(including Japan) tended to be stronger than those in Europe.

The economic recovery in the United States continued. Real gross domestic
product advanced in the first quarter of 2010, though at a slower pace than in
the fourth quarter of 2009. The Federal Open Market Committee kept the targeted
federal funds rate at a historically low level throughout the reporting period,
which prompted many investors to leave the safety of U.S. Treasury securities in
search of higher yield.

In the high-yield bond market, lower-rated credits tended to be the strongest
performers. With investment-grade investors crossing into high-yield territory,
however, the highest-rated high-yield credits also saw strong demand. In the
municipal market, new-issue supply was reduced by government incentives that
encouraged municipal issuers to raise funds in the taxable market. In the
leveraged-loan market, new issuance strengthened, but extensive repayments
caused the market as a whole to contract.


Throughout the six-month reporting period, MainStay's portfolio managers sought
to make the most of market conditions within the investment strategies and risk
parameters of their respective Funds. While individual markets and Fund results
may vary, our pursuit of competitive returns over full market cycles has never
changed.

The information that follows provides a closer look at the securities,
strategies and market conditions that affected your MainStay Fund(s) during the
six months ended April 30, 2010. Of course, past performance is no guarantee of
future results. Even in a rising market, we believe that maintaining a long-term
perspective can be valuable. At MainStay, we believe that in all markets, broad
diversification, gradual allocation adjustments and regular portfolio reviews
can help guide you toward your long-range financial goals.

We thank you for choosing MainStay Funds, and we look forward to serving your
investment needs for many years to come.

Sincerely,

/s/ STEPHEN P. FISHER

Stephen P. Fisher
President

1. Performance tables and graphs do not reflect the deduction of taxes that a
   shareholder would pay on distributions or Fund-share redemptions. Total
   returns reflect maximum applicable sales charges explained in this paragraph,

   distributions. The graphs assume an initial investment of $25,000 for Class A
   shares and $10,000 for all other classes and reflect the deduction of all
   sales charges that would have applied for the period of investment. Class A
   shares generally have a $25,000 minimum initial investment with no minimum

   of $100,000 or more invested in any share classes of any of the MainStay
   Funds, the minimum initial investment is $15,000. Investor Class shares and
   Class A shares are sold with a maximum initial sales charge of 3.00% and an
   annual 12b-1 fee of 0.25%. Class I shares are sold with no initial sales
   charge or contingent deferred sales charge, have no annual 12b-1 fee, and are
   generally available to corporate and institutional investors or individual
   investors with a minimum initial investment of $5 million. Performance
   figures reflect certain fee waivers and/or expense limitations, without which

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY INDEXED BOND FUND (UNAUDITED)
- --------------------------------------------------------------------------------

The example below is intended to describe the fees and expenses borne by
shareholders during the six-month period from November 1, 2009, to April 30,
2010, and the impact of those costs on your investment.

EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, exchange fees, and sales charges (loads) on
purchases (as applicable), and (2) ongoing costs, including management fees,
distribution and/or service (12b-1) fees, and other Fund expenses (as
applicable). This example is intended to help you understand your ongoing costs
(in dollars) of investing in the Fund and to compare these costs with the
ongoing costs of investing in other mutual funds. The example is based on an
investment of $1,000 made at the beginning of the six-month period and held for
the entire period from November 1, 2009, to April 30, 2010.

This example illustrates your Fund's ongoing costs in two ways:

- - ACTUAL EXPENSES
The second and third data columns in the table below provide information about
actual account values and actual expenses. You may use the information in these
columns, together with the amount you invested, to estimate the expenses that
you paid during the six-months ended April 30, 2010. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number under the heading entitled "Expenses Paid
During Period" to estimate the expenses you paid on your account during this
period.

- - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The fourth and fifth data columns in the table below provide information about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense ratio and an assumed rate of return of 5% per year before expenses,
which is not the Fund's actual return. The hypothetical account values and
expenses may not be used to estimate the actual ending account balances or
expenses you paid for the six-month period shown. You may use this information
to compare the ongoing costs of investing in the Fund with the ongoing costs of
investing in other Funds. To do so, compare this 5% hypothetical example with
the 5% hypothetical examples that appear in the shareholder reports of the other
Funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as
redemption fees, if applicable, exchange fees, or sales charges (loads).
Therefore, the fourth and fifth data columns of the table are useful in
comparing ongoing costs only and will not help you determine the relative total

8    MainStay Indexed Bond Fund



PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

QUESTIONS ANSWERED BY PORTFOLIO MANAGERS DONALD F. SEREK AND THOMAS J. GIRARD OF
NEW YORK LIFE INVESTMENTS,(1) THE FUND'S MANAGER.

HOW DID MAINSTAY INDEXED BOND FUND PERFORM RELATIVE TO ITS PEERS AND ITS
BENCHMARK DURING THE SIX MONTHS ENDED APRIL 30, 2010?

Excluding all sales charges, MainStay Indexed Bond Fund returned 1.82% for
Investor Class shares and 1.97% for Class A shares for the six months ended
April 30, 2010. Over the same period, the Fund's Class I shares returned 2.16%.
All share classes underperformed the 4.04% return of the average Lipper(2)
intermediate investment grade debt fund for the six months ended April 30, 2010.
All share classes also underperformed the 2.54% return of the Barclays Capital
U.S. Aggregate Bond Index(3) for the reporting period. The Barclays Capital U.S.
Aggregate Bond Index is the Fund's broad-based securities-market index. See page
5 for Fund returns with sales charges.

WHAT FACTORS HAD A MAJOR IMPACT ON BOND MARKET PERFORMANCE DURING THE REPORTING
PERIOD?

During the six months ended April 30, 2010, the economic recovery appeared to
gain momentum and the financial markets continued to rebound. The equity markets
hit a low point in March of 2009, and spreads(4) on non-Treasury bonds appeared
to hit their widest levels at roughly the same time. Throughout the reporting
period, the equity markets recovered and spreads tightened significantly. Assets
also flowed out of money market funds in search of higher yields. A large
portion of that money was reallocated to the fixed-income market, particularly
to corporate bonds.

Because inflation remained relatively low, the Federal Reserve was able to sit
on the sidelines and exercise patience in its monetary policy decisions. It
allowed most of its emergency programs expire, with little discernable impact on
the bond market. Federal Reserve forecasts include keeping short-term interest
rates very low for an extended period of time.


The economy continued to show modest improvement during the reporting period,
but the recovery was subpar relative to other recoveries. The most glaring
weakness was the labor market, which has only recently begun to create jobs.
Unemployment remained unacceptably high, and policy makers appeared to be
waiting for meaningful improvements before significantly tightening monetary
policy.

Uncertainty about U.S. financial reform legislation and its impact on financial
institutions kept spreads on bank and finance paper wider than normal relative
to spreads on utility and industrial bonds. Concerns surrounding Greek sovereign
debt--and whether there would be a default or a bailout--created volatility in
the U.S. Treasury market and the corporate bond market.

HOW DID SECURITIES IN DIFFERENT RATING CATEGORIES PERFORM DURING THE REPORTING
PERIOD?

Broadly speaking, higher-risk bonds tended to outperform bonds with lower-risk.
By rating category, the Fund's best-performing sector was BBB-rated bonds.(5)
The worst-performing ratings category was AAA-rated bonds.

WHICH SECTORS WERE THE STRONGEST PERFORMERS DURING THE REPORTING PERIOD AND
WHICH SECTORS DETRACTED THE MOST?

The best-performing sectors were corporate bonds and commercial mortgage-backed
securities. During the reporting period, attractive valuations, high levels of
liquidity and continued risk-taking led investors to allocate significant
capital to corporate bonds, commercial mortgage-backed securities and other non-
Treasury debt instruments. As a result, spreads--or the differences in yield
between these securities and duration-equivalent(6) U.S. Treasurys--tightened
dramatically.

   Investment Management LLC.
2. See footnote on page 6 for more information on Lipper Inc.
3. See footnote on page 6 for more information on the Barclays Capital U.S.
   Aggregate Bond Index.
4. The terms "spread" and "yield spread" may refer to the difference in yield
   between a security or type of security and comparable U.S. Treasury issues.
   The terms may also refer to the difference in yield between two specific
   securities or types of securities at a given time.
5. Debt rated AAA has the highest rating assigned by Standard & Poor's, and in
   the opinion of Standard & Poor's, the obligor's capacity to meet its
   financial commitment on the obligation is extremely strong. Debt rated BBB by
   Standard & Poor's is deemed by Standard & Poor's to exhibit adequate
   protection parameters. It is the opinion of Standard & Poor's, however, that
   adverse economic conditions or changing circumstances are more likely to lead
   to a weakened capacity of the obligor to meet its financial commitment on the
   obligation than would be the case for debt in higher-rated categories.
6. Duration is a measure of the price sensitivity of a fixed-income investment
   to changes in interest rates. Duration is expressed as a number of years and
   is considered a more accurate sensitivity gauge than average maturity.

During the reporting period, the worst-performing sectors were U.S. Treasurys
and government agency securities. While these two sectors generated positive
total returns, they underperformed other sectors primarily because investors
manifested a thirst for higher yield, a willingness to take on more risk, and
ongoing concerns about the ever-increasing supply of government debt.

DID THE FUND MAKE ANY SIGNIFICANT PURCHASES OR SALES DURING THE REPORTING
PERIOD?

Purchases and sales were limited to those needed to keep the Fund's exposures
consistent with those of the Barclays Capital U.S. Aggregate Bond Index.

NOTES TO FINANCIAL STATEMENTS UNAUDITED

NOTE 1--ORGANIZATION AND BUSINESS:

MainStay Funds Trust (the "Trust") is organized as a Delaware Statutory Trust
and is governed by a Declaration of Trust dated April 8, 2009. The Trust is
registered under the Investment Company Act of 1940, as amended (the "1940
Act"), as an open-end management investment company, and is comprised of twenty-
nine funds (collectively referred to as the "Funds"). These financial statements
and notes relate only to the MainStay Indexed Bond Fund (the "Fund"), a
diversified fund. The Fund is the successor of the MainStay Indexed Bond Fund, a
series of Eclipse Funds Inc. (the "Predecessor Fund"). The reorganization of the
Predecessor Fund with and into the Fund, which was not subject to shareholder
approval under applicable law, occurred on February 26, 2010. All information
regarding and references to periods prior to the commencement of operations of
the Fund relate to the Predecessor Fund.

The Fund currently offers three classes of shares. Class I shares commenced
operations on January 2, 1991. Class A shares commenced operations on January 2,
2004. Investor Class shares commenced operations on February 28, 2008. Investor
Class and Class A shares are offered at net asset value ("NAV") per share plus
an initial sales charge. No sales charge applies on investments of $1 million or
more (and certain other qualified purchases) in Investor Class and Class A
shares, but a contingent deferred sales charge is imposed on certain redemptions
of such shares within one year of the date of purchase. Class I shares are
offered at NAV and are not subject to a sales charge. Depending upon
eligibility, Investor Class shares may convert to Class A shares and Class A
shares may convert to Investor Class shares. The three classes of shares have
the same voting (except for issues that relate solely to one class), dividend,
liquidation and other rights, and the same terms and conditions. Class I shares
are not subject to a distribution and/or service fee.

The Fund's investment objective is to seek to provide investment results that
correspond to the total return performance of fixed-income securities in the
aggregate, as represented by the Fund's primary benchmark index.

NOTE 2--SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with accounting
principles generally accepted in the United States of America ("GAAP") and
follows the significant accounting policies described below.

(A) SECURITIES VALUATION.  Debt securities are valued at prices supplied by a
pricing agent or broker selected by the Fund's Manager (as defined in Note 3(A))
in consultation with the Fund's Subadvisor, if any (as defined in Note 3(A)),
whose prices reflect broker/dealer supplied valuations and electronic data
processing techniques, if such prices are deemed by the Fund's Manager, in
consultation with the Fund's Subadvisor, if any, to be representative of market
values, at the regular close of trading of the New York Stock Exchange
("Exchange") (generally 4:00 p.m. Eastern time) on each day the Fund is open for
business ("valuation date"). Futures contracts are valued at the last posted
settlement price on the market where such futures are primarily traded.
Investments in other mutual funds are valued at their NAVs as of the close of
the Exchange on the valuation date.

Temporary cash investments acquired over 60 days prior to maturity are valued
using the latest bid prices or using valuations based on a matrix system (which
considers such factors as security prices, yields, maturities, and ratings),
both as furnished by independent pricing services. Other temporary cash
investments which mature in 60 days or less ("short-term investments") are
valued at amortized cost. The amortized cost method involves valuing a security
at its cost on the date of purchase and thereafter assuming a constant
amortization to maturity of the difference between the principal amount due at
maturity and cost.

Securities for which market quotations are not readily available are valued by
methods deemed in good faith by the Fund's Board to represent fair value. Equity
and non-equity securities which may be valued in this manner include, but are
not limited to: (i) a security the trading for which has been halted or
suspended; (ii) a debt security that has recently gone into default and for
which there is not a current market quotation; (iii) a security of an issuer
that has entered into a restructuring; (iv) a security that has been de-listed
from a national exchange; (v) a security the market price of which is not
available from an independent pricing source or, if so provided, does not, in
the opinion of the Fund's Manager or Subadvisor, as defined in Note 3(A),
reflect the security's market value; and (vi) a security where the trading on
that security's principal market is temporarily closed at a time when, under
normal conditions, it would be open. At April 30, 2010, the Fund did not hold
securities that were valued in such a manner.

"Fair value" is defined as the price that the Fund would receive upon selling an
investment in an orderly transaction to an independent buyer in the principal or
most advantageous market of the investment. Fair value measurements are
determined within a framework that has established a three-tier hierarchy which
maximizes the use of observable market data and minimizes the use of
unobservable inputs to establish classification of fair value measurements for
disclosure purposes. "Inputs" refer broadly to the assumptions that market
participants would use in pricing the asset or liability, including assumptions
about risk, such as the risk inherent in a particular valuation technique used
to measure fair value using a pricing model and/or the risk inherent in the
inputs for the valuation technique. Inputs may be observable or unobservable.
Observable inputs are inputs that reflect the assumptions market participants
would use in pricing the asset or liability based on market data obtained from
sources independent of the reporting entity. Unobservable inputs are inputs that
reflect the

34    MainStay Indexed Bond Fund



reporting entity's own assumptions about the assumptions market participants
would use in pricing the asset or liability developed based on the information
available in the circumstances. The inputs or methodology used for valuing
securities may not be an indication of the risks associated with investing in
those securities. The three-tier hierarchy of inputs is summarized in the three
broad Levels listed below.

- - Level 1--quoted prices in active markets for identical investments

- - Level 2--other significant observable inputs (including quoted prices for
  similar investments in active markets, interest rates and yield curves,
  prepayment speeds, credit risks, etc.)

- - Level 3--significant unobservable inputs (including the Fund's own assumptions
  about the assumptions that market participants would use in determining the
  fair value of investments)

The aggregate value by input level, as of April 30, 2010, for the Fund's
investments is included at the end of the Fund's Portfolio of Investments.

The valuation techniques used by the Fund to measure fair value during the six-
month period ended April 30, 2010 maximized the use of observable inputs and
minimized the use of unobservable inputs. The Fund may have utilized some of the
following fair value techniques: multi-dimensional relational pricing models,
option adjusted spread pricing and estimating the price that would have
prevailed in a liquid market for an international equity security given
information available at the time of evaluation, when there are significant
events after the close of local foreign markets. For the six-month period ended
April 30, 2010, there have been no changes to the fair value methodologies.

(B) FEDERAL INCOME TAXES.  The Fund's policy is to comply with the requirements
of the Internal Revenue Code of 1986, as amended (the "Internal Revenue Code")
applicable to regulated investment companies and to distribute all of the
taxable income to the shareholders of the Fund within the allowable time limits.
Therefore, no federal income tax provision is required.

Management evaluates its tax positions to determine if the tax positions taken
meet the minimum recognition threshold in connection with accounting for
uncertainties in income tax positions taken or expected to be taken for the
purposes of measuring and recognizing tax liabilities in the financial
statements. Recognition of tax benefits of an uncertain tax position is required
only when the position is "more likely than not" to be sustained assuming
examination by taxing authorities. Management has analyzed the Fund's tax
positions taken on federal income tax returns for all open tax years (current
and prior three tax years), and has concluded that no provision for federal
income tax is required in the Fund's financial statements. The Fund's federal
and state income and federal excise tax returns for tax years for which the
applicable statutes of limitations have not expired are subject to examination
by the Internal Revenue Service and state departments of revenue.

(C) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS.  Dividends and distributions
are recorded on the ex-dividend date. The Fund intends to declare and pay
dividends of net investment income monthly and distributions of net realized
capital and currency gains, if any, annually, Unless the shareholder elects
otherwise, all dividends and distributions are reinvested in the same class of
shares of the Fund, at NAV. Dividends and distributions to shareholders are
determined in accordance with federal income tax regulations and may differ from
GAAP.

(D) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  The Fund records security
transactions on the trade date. Realized gains and losses on security
transactions are determined using the identified cost method and include gains
and losses from repayments of principal on mortgage-backed securities. Interest
income is accrued as earned using the effective interest rate method. Discounts
and premiums on securities purchased, other than short-term investments, for the
Fund are accreted and amortized, respectively, on the effective interest rate
method over the life of the respective securities or, in the case of a callable
security, over the period to the first date of call. Discounts and premiums on
short-term investments are accreted and amortized, respectively, on the
straight-line method. Income from payment-in-kind securities is recorded daily
based on the effective interest method of accrual.

Investment income and realized and unrealized gains and losses on investments of
the Fund are allocated to separate classes of shares pro rata based upon their
relative net assets on the date the income is earned or realized and unrealized
gains and losses are incurred.

(E) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred, except where direct allocations of expenses can be made. Expenses
(other than transfer agent expenses and fees incurred under the shareholder
services plans and the distribution plans further discussed in Note 3(B)) are
allocated to separate classes of shares pro rata based upon their relative NAV
on the date the expenses are incurred. The expenses borne by the Fund, including
those of related parties to the Fund, are shown in the Statement of Operations.

(F) USE OF ESTIMATES.  In preparing financial statements in conformity with
GAAP, management makes estimates and assumptions that affect the reported
amounts and disclosures in the financial statements. Actual results could differ
from those estimates.

(G) REPURCHASE AGREEMENTS.  The Fund may enter into repurchase agreements to
earn income. The Fund may

                                                   mainstayinvestments.com    35



NOTES TO FINANCIAL STATEMENTS UNAUDITED (CONTINUED)


enter into repurchase agreements only with financial institutions that are
deemed by the Manager or Subadvisor to be creditworthy, pursuant to guidelines
established by the Fund's Board. Repurchase agreements are considered under the
1940 Act to be collateralized loans by a Fund to the seller secured by the
securities transferred to the Fund.

When the Fund invests in repurchase agreements, the Fund's custodian takes
possession of the collateral pledged for investments in such repurchase
agreements. The underlying collateral is valued daily on a mark-to-market basis
to determine that the value, including accrued interest, exceeds the repurchase
price. In the event of the seller's default of the obligation to repurchase, the
Fund has the right to liquidate the collateral and apply the proceeds in
satisfaction of the obligation. Under certain circumstances, in the event of
default or bankruptcy by the other party to the agreement, realization and/or
retention of the collateral may be subject to legal proceedings and possible
realized loss to the Fund.

(H) MORTGAGE DOLLAR ROLLS.  The Fund may enter into mortgage dollar roll ("MDR")
transactions in which it sells mortgage-backed securities ("MBS") from its
portfolio to a counterparty from whom it simultaneously agrees to buy a similar
security on a delayed delivery basis. The MDR transactions of the Fund are
classified as purchase and sale transactions. The securities sold in connection
with the MDRs are removed from the portfolio and a realized gain or loss is
recognized. The securities the Fund has agreed to acquire are included at market
value in the Portfolio of Investments and liabilities for such purchase
commitments are included as payables for investments purchased. During the roll
period, the Fund foregoes principal and interest paid on the securities. The
Fund is compensated by the difference between the current sales price and the
forward price for the future as well as by the earnings on the cash proceeds of
the initial sale. MDRs may be renewed without physical delivery of the
securities subject to the contract. The Fund maintains liquid assets from its
portfolio having a value not less than the repurchase price, including accrued
interest. MDR transactions involve certain risks, including the risk that the
MBS returned to the Fund at the end of the roll, while substantially similar,
could be inferior to what was initially sold to the counterparty.

(I) SECURITIES LENDING.  In order to realize additional income, the Fund may
engage in securities lending, subject to the limitations set forth in the 1940
Act, and relevant guidance by the staff of the Securities and Exchange
Commission. In the event the Fund does engage in securities lending, the Fund
will lend through its custodian, State Street Bank and Trust Company ("State
Street"). State Street will manage the Fund's cash collateral in accordance with
the Lending Agreement between the Fund and State Street, and indemnify the
Fund's portfolio against counterparty risk. The loans will be collateralized by
cash or securities at least equal at all times to the market value of the
securities loaned. Collateral will consist of U.S. Government securities, cash
equivalents or irrevocable letters of credit. The Fund may bear the risk of
delay in recovery of, or loss of rights in, the securities loaned should the
borrower of the securities experience financial difficulty. The Fund may also
record realized gain or loss on securities deemed sold due to a borrower's
inability to return securities on loan. The Fund will receive compensation for
lending its securities in the form of fees or retain a portion of interest on
the investment of any cash received as collateral. The Fund also will continue
to receive interest and dividends on the securities loaned and any gain or loss
in the market price of the securities loaned that may occur during the term of
the loan will be for the account of the Fund.

Although the Fund and New York Life Investments (as defined in Note 3(A)) have
temporarily suspended securities lending, the Fund and New York Life Investments
reserve the right to reinstitute lending when deemed appropriate. The Fund had
no portfolio securities on loan as of April 30, 2010.

(J) CONCENTRATION OF RISK.  The Fund invests in foreign securities, which carry
certain risks that are in addition to the usual risks inherent in domestic
instruments. These risks include those resulting from currency fluctuations,
future adverse political and economic developments and possible imposition of
currency exchange blockages or other foreign governmental laws or restrictions.
These risks are likely to be greater in emerging markets than in developed
markets. The ability of issuers of debt securities held by the Fund to meet
their obligations may be affected by economic or political developments in a
specific country, industry or region.

(K) INDEMNIFICATIONS.  Under the Trust's organizational documents, its officers
and trustees are indemnified against certain liabilities that may arise out of
performance of their duties to the Trust. Additionally, in the normal course of
business, the Fund enters into contracts with third-party service providers that
contain a variety of representations and warranties and which provide general
indemnifications. The Fund's maximum exposure under these arrangements is
unknown, as this would involve future claims that may be made against the Fund
that have not yet occurred. Based on experience, management is of the view that
the risk of loss in connection with these potential indemnification obligations
is remote. However, there can be no assurance that material liabilities related
to such obligations will not arise in the future, which could adversely impact
the Fund.

NOTE 3--FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER.  New York Life Investment Management LLC ("New York Life
Investments" or "Manager"), a registered investment adviser and an indirect,
wholly-owned subsidiary of New York Life Insurance Company ("New

36    MainStay Indexed Bond Fund



York Life"), serves as the Fund's Manager, pursuant to a Management Agreement
("Management Agreement"). The Manager provides offices, conducts clerical,
recordkeeping and bookkeeping services, and keeps most of the financial and
accounting records required to be maintained by the Fund. Except for the portion
of salaries and expenses that are the responsibility of the Fund, the Manager
also pays the salaries and expenses of all personnel affiliated with the Fund
and the operational expenses of the Fund. The Fund is advised by New York Life
Investments directly, without a subadvisor.

The Fund pays the Manager a monthly fee for services performed and facilities
furnished at an annual rate of the Fund's average daily net assets as follows:
0.35% on assets up to $1 billion and 0.30% on assets in excess of $1 billion.
The effective management fee rate (exclusive of any applicable
waivers/reimbursements) was 0.35% for the six-month period ended April 30, 2010.

Effective February 26, 2010, New York Life Investments entered into a written
expense limitation agreement, under which it agreed to waive a portion of the
management fee or reimburse expenses of the appropriate class of the Fund to the
extent necessary to ensure that the total ordinary operating expenses (total
ordinary operating expenses excludes taxes, interest, litigation, extraordinary
expenses, brokerage, other transaction expenses relating to the purchase or sale
of portfolio investments, and the fees and expenses of any other funds in which
the Fund invests) do not exceed the following percentages of average daily net
assets: Investor Class, 0.92%; Class A, 0.82%; and Class I, 0.43%. This
agreement expires on July 31, 2010, and is reviewed annually by the Board in
connection with its review of the Fund's investment advisory agreements. Based
on its review, the Board may agree to maintain, modify or terminate the
agreement.

For the period August 1, 2009 to February 25, 2010, New York Life Investments
had a written expense limitation agreement under which it agreed to waive a
portion of the management fee or reimburse expenses to the extent necessary to
ensure that the total ordinary operating expenses for the Fund's Class A shares
do not exceed 0.82% of its average net assets. While applying an equivalent
waiver or reimbursement, in an equal number of basis points, to the other share
classes of the Fund. Additionally, New York Life Investments had agreed to
voluntarily waive or reimburse the expenses of the appropriate class of the Fund
so that the total annual operating expenses of a class do not exceed the
following percentages: Investor Class, 0.92%, and Class I, 0.43%.

For the six-month period ended April 30, 2010, New York Life Investments earned
fees from the Fund in the amount of $997,179 and waived/reimbursed its fees in
the amount of $336,078.

State Street, 1 Lincoln Street, Boston, Massachusetts 02111, provides sub-
administration and sub-accounting services to the Fund pursuant to an agreement
with New York Life Investments. These services include calculating the daily
NAVs of the Fund, maintaining the general ledger and sub-ledger accounts for the
calculation of the Fund's respective NAVs, and assisting New York Life
Investments in conducting various aspects of the Fund's administrative
operations. For providing these services to the Fund, State Street is
compensated by New York Life Investments.

(B) DISTRIBUTION AND SERVICE FEES.  The Trust, on behalf of the Fund, has
entered into a Distribution Agreement with NYLIFE Distributors LLC (the
"Distributor"), an indirect, wholly-owned subsidiary of New York Life. The Fund
has adopted distribution plans, (the "Plans") in accordance with the provisions
of Rule 12b-1 under the 1940 Act.

Pursuant to the Investor Class and Class A Plans, the Distributor receives a
monthly distribution fee from the Investor Class and Class A shares at an annual
rate of 0.25% of the average daily net assets of the Investor Class and Class A
shares for distribution or service activities as designated by the Distributor.
Class I shares are not subject to a distribution or service fee.

The Plans provide that the distribution and service fees are payable to the
Distributor regardless of the amounts actually expended by the Distributor for
distribution of the Fund's shares and service activities.

(C) SALES CHARGES.  The Fund was advised by the Distributor that the amount of
sales charges retained on sales of Investor Class and Class A shares were $1,674
and $6,428, respectively, for the six-month period ended April 30, 2010. The
Fund was also advised that the Distributor retained contingent deferred sales
charges on redemptions of Class A of $279, for the six-month period ended April
30, 2010.

(D) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT.  NYLIM
Service Company LLC, an affiliate of New York Life Investments, is the Fund's
transfer, dividend disbursing and shareholder servicing agent pursuant to an
agreement between NYLIM Service Company LLC and the Trust. NYLIM Service Company
LLC has entered into an agreement with Boston Financial Data Services, Inc.
("BFDS") pursuant to which BFDS performs certain transfer agent services on
behalf of NYLIM Service Company LLC. Transfer agent expenses incurred by the
Fund for the six-month period ended April 30, 2010, were as follows:

NOTES TO FINANCIAL STATEMENTS UNAUDITED (CONTINUED)

(E) SMALL ACCOUNT FEE.  Shareholders with small accounts adversely impact the
cost of providing transfer agency services. In an effort to reduce total
transfer agency expenses, the Fund has implemented a small account fee on

annually). These fees are included in transfer agent fees shown on the Statement
of Operations.

is an annual rate of 0.10% of the average commitment amount, plus a 0.04% up-
front payment payable, regardless of usage, to The Bank of New York Mellon,

(a) In addition to any automatic conversion features described above in Note 1
    with respect to Investor Class, Class A and B shares, you generally may also
    elect to convert your shares on a voluntary basis into another share class
    of the same fund for which you are eligible. However, the following
    limitations apply:

    - Investor Class and Class A shares that remain subject to a CDSC are
      ineligible for a voluntary conversion; and

    - All Class B and C shares are ineligible for a voluntary conversion.

These limitations do not impact any automatic conversion features described in
Note 1 with respect to Investor Class, Class A and B shares.

An investor or an investor's financial intermediary may contact the Fund to
request a voluntary conversion between shares classes of the same Fund. You may
be required to provide sufficient information to establish eligibility to
convert to the new share class. All permissible conversions will be made on the
basis of the relevant NAVs of the two classes without the imposition of any
sales load, fee or other charge. If you fail to remain eligible for the new
share class, you may automatically be converted back to your original share
class, or into another share class, if appropriate.

NOTE 9--NEW ACCOUNTING PRONOUNCEMENT:

In January 2010, the Financial Accounting Standards Board ("FASB") issued
Accounting Standards Update ("ASU") No. 2010-06 "Improving Disclosures about
Fair Value Measurements". ASU 2010-06 requires reporting entities to make new
disclosures about amount and reasons for significant transfers in and out of
Level 1 and Level 2 fair value measurements and input and valuation techniques
used to measure fair value for both recurring and nonrecurring fair value
measurements that fall in either Level 2 or Level 3, and information on
purchased, sales, issuances, and settlements in the roll forward of activity in
Level 3 fair value measures. The new and revised disclosure requirements are
effective for interim and annual reporting periods beginning after December 15,
2009 except for the disclosures about purchased, sales, issuances, and
settlements in the roll forward of activity in Level 3 fair value measures,
which are effective for fiscal years beginning after December 15, 2010. As of
April 30, 2010, the Fund has adopted ASU 2010-06. The adoption of ASU 2010-06
has not impacted the amounts reported in the financial statements; however,
there are additional disclosures in the Portfolio of Investments.

NOTE 10--SUBSEQUENT EVENTS:

In connection with the preparation of the financial statements of the Fund as of
and for the fiscal six-month period ended April 30, 2010, events and
transactions subsequent to April 30, 2010 through the date the financial
statements were issued have been evaluated by the Fund's management for possible
adjustment and/or disclosure. No subsequent events requiring financial statement
adjustment or disclosure have been identified.

        MESSAGE FROM THE PRESIDENT AND SEMIANNUAL REPORT

        Unaudited - April 30, 2010



MESSAGE FROM THE PRESIDENT

During the six months ended April 30, 2010, stock and bond markets generally
advanced, despite some volatility in January and February. Domestic small-cap
stocks were particularly strong, and U.S. stocks at all capitalization levels
provided double digit returns. Value stocks outpaced growth stocks for companies
of all sizes during the reporting period.

International stocks provided positive returns overall, but results varied
widely by country. Concerns about Greece's ability to meet its debt obligations
led many investors to abandon their holdings in Greece and question their
investments in several peripheral European nations where perceived risk had
increased. For the six-month reporting period, equities in the Far East
(including Japan) tended to be stronger than those in Europe.

The economic recovery in the United States continued. Real gross domestic
product advanced in the first quarter of 2010, though at a slower pace than in
the fourth quarter of 2009. The Federal Open Market Committee kept the targeted
federal funds rate at a historically low level throughout the reporting period,
which prompted many investors to leave the safety of U.S. Treasury securities in
search of higher yield.

In the high-yield bond market, lower-rated credits tended to be the strongest
performers. With investment-grade investors crossing into high-yield territory,
however, the highest-rated high-yield credits also saw strong demand. In the
municipal market, new-issue supply was reduced by government incentives that
encouraged municipal issuers to raise funds in the taxable market. In the
leveraged-loan market, new issuance strengthened, but extensive repayments
caused the market as a whole to contract.


Throughout the six-month reporting period, MainStay's portfolio managers sought
to make the most of market conditions within the investment strategies and risk
parameters of their respective Funds. While individual markets and Fund results
may vary, our pursuit of competitive returns over full market cycles has never
changed.

The information that follows provides a closer look
at the securities, strategies and market conditions that affected your MainStay
Fund(s) during the six months ended April 30, 2010. Of course, past performance
is no guarantee of future results. Even in a rising market, we believe that
maintaining a long-term perspective can be valuable. At MainStay, we believe
that in all markets, broad diversification, gradual allocation adjustments and
regular portfolio reviews can help guide you toward your long-range financial
goals.

We thank you for choosing MainStay Funds, and we look forward to serving your
investment needs for many years to come.

Sincerely,

/s/ STEPHEN P. FISHER

Stephen P. Fisher
President

1. Performance tables and graphs do not reflect the deduction of taxes that a
   shareholder would pay on distributions or Fund-share redemptions. Total
   returns reflect maximum applicable sales charges explained in this paragraph,
   change in share price, and reinvestment of dividend and capital gain
   distributions. The graphs assume an initial investment of $25,000 for Class A
   shares and $10,000 for all other classes and reflect the deduction of all
   sales charges that would have applied for the period of investment. Class A
   shares generally have a $25,000 minimum initial investment with no minimum
   subsequent purchase amount. For investors that, in the aggregate, have assets
   of $100,000 or more invested in any share classes of any of the MainStay
   Funds, the minimum initial investment is $15,000. Investor Class shares and
   Class A shares are sold with a maximum initial sales charge of 4.50% and an
   annual 12b-1 fee of 0.25%. Class B shares are sold with no initial sales
   charge, are subject to a contingent deferred sales charge ("CDSC") of up to
   5.00% if redeemed within the first six years of purchase, and have an annual
   12b-1 fee of 1.00%. Class C shares are sold with no initial sales charge, are
   subject to a CDSC of 1.00% if redeemed within one year of purchase, and have
   an annual 12b-1 fee of 1.00%. Class I shares are sold with no initial sales
   charge or CDSC, have no annual 12b-1 fee, and are generally available to
   corporate and institutional investors or individual investors with a minimum
   initial investment of $5 million. Performance figures reflect certain fee
   waivers and/or expense limitations, without which total returns may have been
   lower. For information on current fee waivers and/or expense limitations,
   please refer to the notes to the financial statements.
2. Performance figures for Investor Class shares, first offered on February 28,
   2008, include the historical performance of Class A shares through February
   27, 2008, adjusted for differences in certain contractual fees and expenses.

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY INTERMEDIATE TERM BOND FUND
(UNAUDITED)
- --------------------------------------------------------------------------------

The example below is intended to describe the fees and expenses borne by
shareholders during the six-month period from November 1, 2009, to April 30,
2010, and the impact of those costs on your investment.

EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, exchange fees, and sales charges (loads) on
purchases (as applicable), and (2) ongoing costs, including management fees,
distribution and/or service (12b-1) fees, and other Fund expenses (as
applicable). This example is intended to help you understand your ongoing costs
(in dollars) of investing in the Fund and to compare these costs with the
ongoing costs of investing in other mutual funds. The example is based on an
investment of $1,000 made at the beginning of the six-month period and held for
the entire period from November 1, 2009, to April 30, 2010.

This example illustrates your Fund's ongoing costs in two ways:

- - ACTUAL EXPENSES
The second and third data columns in the table below provide information about
actual account values and actual expenses. You may use the information in these
columns, together with the amount you invested, to estimate the expenses that
you paid during the six-months ended April 30, 2010. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number under the heading entitled "Expenses Paid
During Period" to estimate the expenses you paid on your account during this
period.

- - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The fourth and fifth data columns in the table below provide information about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense ratio and an assumed rate of return of 5% per year before expenses,
which is not the Fund's actual return. The hypothetical account values and
expenses may not be used to estimate the actual ending account balances or
expenses you paid for the six-month period shown. You may use this information
to compare the ongoing costs of investing in the Fund with the ongoing costs of
investing in other Funds. To do so, compare this 5% hypothetical example with
the 5% hypothetical examples that appear in the shareholder reports of the other
Funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as
redemption fees, if applicable, exchange fees, or sales charges (loads).
Therefore, the fourth and fifth data columns of the table are useful in
comparing ongoing costs only and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.

1. Expenses are equal to the Fund's annualized expense ratio of each class
   (1.05% for Investor Class, 0.91% for Class A, 1.80% for Class B and Class C
   and 0.59% for Class I) multiplied by the average account value over the
   period, divided by 365 and multiplied by 181 (to reflect the one-half year
   period). The table above represents the actual expenses incurred during the
   one-half year period.

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

QUESTIONS ANSWERED BY PORTFOLIO MANAGERS GARY GOODENOUGH AND JAMES RAMSAY, CFA,
OF MACKAY SHIELDS LLC, THE FUND'S SUBADVISOR.

HOW DID MAINSTAY INTERMEDIATE TERM BOND FUND PERFORM RELATIVE TO ITS PEERS AND
ITS BENCHMARK DURING THE SIX MONTHS ENDED APRIL 30, 2010?

Excluding all sales charges, MainStay Intermediate Term Bond Fund returned 3.61%
for Investor Class shares, 3.80% for Class A shares, 3.34% for Class B shares
and 3.34% for Class C shares for the six months ended April 30, 2010. Over the
same period, the Fund's Class I shares returned 3.96%. All share classes
underperformed the 4.04% return of the average Lipper(1) intermediate investment
grade debt fund for the six-month reporting period. All share classes
outperformed the 2.54% return of the Barclays Capital U.S. Aggregate Bond
Index(2) for the six months ended April 30, 2010. The Barclays Capital U.S.
Aggregate Bond Index is the Fund's broad-based securitiesmarket index. See pages
5 and 6 for Fund returns with sales charges.

WHAT FACTORS CONTRIBUTED TO THE FUND'S RELATIVE PERFORMANCE DURING THE REPORTING
PERIOD?

Relative to the Barclays Capital U.S. Aggregate Bond Index, the Fund benefited
from overweight positions in corporate bonds, commercial mortgage-backed
securities and asset-backed securities. A modest allocation to mortgage-backed
securities collateralized by jumbo residential loans larger than the conforming
standards of Fannie Mae and Freddie Mac added value as well. Individual issue
selection among investment-grade corporate bonds, especially a bias toward bonds
rated BBB,(3) also helped. Nimble use of the new-issue calendar and a variety of
well-timed sales further strengthened the Fund's relative performance.

A less aggressive position in corporate bonds and non-investment-grade
securities along with a bias toward a flatter Treasury yield curve(4) detracted
from the Fund's results relative to its Lipper peers during a period when the
yield curve steepened.

HOW DID THE FUND INVEST DURING THE REPORTING PERIOD?

Early in 2009, the Federal Reserve formally adopted and implemented quantitative
easing, a way to expand the money supply through direct security purchases.
Policymakers intended to purchase $300 billion of longer-term Treasurys, $1.25
trillion of agency mortgage-backed securities, and $200 billion of agency debt.
As these purchase programs wound to conclusion in 2010, we rotated Fund assets
away from these sectors toward purchases of corporate bonds and commercial
mortgage-backed securities. We expected these fixed-income sectors would have
better total returns than government-related debt for two reasons. First,
prospects for both credit-related sectors were aligned with an improving
economy, implying positive price returns as spreads(5) to U.S. Treasury
securities tightened. Second, there was healthy investor demand for higher-
yielding products during the reporting period. The strategy benefited the Fund's
performance.

At the same time, the Federal Reserve's resolve to maintain its targeted federal
funds rate near zero helped quiet interest-rate volatility. This gave us the
confidence we needed to put an emphasis on higher-coupon mortgage-backed
securities that offer better yields than the sector average. The higher yield
helped compensate for the risk of unpredictable cash flows from the securities.
That risk is diminished when interest-rate volatility is subdued and U.S.
Treasury security yields remain range-bound.

The housing sector strengthened during the reporting period, and we established
a Fund position in securities tied to jumbo residential mortgages. We believed
that these securities had better opportunities to appreciate in price from their
distressed levels in the spring of 2009.

Through coupon income and spread narrowing, both mortgage-backed strategies
added value to the Fund's results relative to its benchmark during the reporting
period.



1. See footnote on page 6 for more information on Lipper Inc.
2. See footnote on page 6 for more information on the Barclays Capital U.S.
   Aggregate Bond Index.
3. Debt rated BBB by Standard & Poor's is deemed by Standard & Poor's to exhibit
   adequate protection parameters. It is the opinion of Standard & Poor's,
   however, that adverse economic conditions or changing circumstances are more
   likely to lead to a weakened capacity of the obligor to meet its financial
   commitment on the obligation than would be the case for debt in higher-rated
   categories. When applied to Fund holdings ratings are based solely on the
   creditworthiness of the bonds in the portfolio and are not meant to represent
   the security or safety of the Fund.
4. The yield curve is a line that plots the yields of various securities of
   similar quality--typically U.S. Treasury issues--across a range of
   maturities. The U.S. Treasury yield curve serves as a benchmark for other
   debt and is used in economic forecasting. The U.S. Treasury yield curve is
   said to flatten when the differential in yield between shorter-maturity and
   longer-maturity Treasury securities narrows.
5. The terms "spread" and "yield spread" may refer to the difference in yield
   between a security or type of security and comparable U.S. Treasury issues.
   The terms may also refer to the difference in yield between two specific
   securities or types of securities at a given time.

WHICH FIXED-INCOME SECTORS CONTRIBUTED MOST POSITIVELY TO THE FUND'S RELATIVE
PERFORMANCE DURING THE REPORTING PERIOD?

Overweight allocations to investment-grade corporate bonds, high-yield corporate
bonds and commercial mortgage-backed securities were positive contributors to
the Fund's relative performance during the reporting period, as the average
spread on each of these sectors narrowed significantly.

Effective issue selection within investment-grade corporate bonds also
contributed positively to the Fund's performance during the reporting period. In
an environment where liquidity premiums receded, the Fund benefited from
increased exposure to corporate issuers that were less mainstream, such as
Teachers Insurance, Agribank and Prologis. We also positioned the Fund for a
recovery in the financials sector by increasing exposure to regional banks such
as Regions Financial and KeyBank. Further, when we liked a company's prospects,
we bought bonds across the issuer's yield curve rather than restricting our
attention to a single maturity. This strategy allowed the Fund to more fully
participate in gains as a company's credit fundamentals improved. Examples where
this strategy was adopted with positive results included Altria, Coventry Health
Care, Williams Partners, NGPL Pipeco and Dow Chemical.

As mentioned earlier, securities tied to jumbo residential mortgages appreciated
in price and added value. The price action reflected investors' expectations
about the future performance of the underlying loans.

WHAT INVESTMENT DECISIONS DETRACTED MOST FROM THE FUND'S RELATIVE RESULTS DURING
THE REPORTING PERIOD?

We favored intermediate-duration over short-duration corporate bonds. This view
imposed a yield-curve flattening bias that detracted from performance.

Transaction costs in increasing allocations to high-yield corporate bonds and
commercial mortgage-backed securities tempered gains from the Fund's overweight
positions in these sectors. Also, the Fund held positions in Royal Bank of
Scotland, Telecom Italia and multinational electric utility Enel that carried
exposure to peripheral Eurozone countries whose economies were under stress.
Moreover, some of the Fund's non-investment-grade holdings in the gaming and
lodging sector and the wireless telecommunications sector had sluggish
performance relative to the broader high-yield corporate bond universe. Gaming
and lodging issues that disappointed were Starwood Hotels & Resorts Worldwide,
Penn National Gaming and Peninsula Gaming. Wireless telecommunications
detractors included Sprint Nextel, Inmarsat and SBA Communications.

WHAT WAS THE FUND'S DURATION DURING THE REPORTING PERIOD?

The Fund maintained an intermediate duration(6) near 4.0 years and made modest
technical adjustments depending on the direction we felt interest rates were
likely to move over the near- to medium-term. Given the rise in Treasury yields
during the reporting period, the Fund would have benefited more from a shorter
duration.

DID THE FUND MAKE ANY SIGNIFICANT PURCHASES OR SALES DURING THE REPORTING
PERIOD?

During the reporting period, we sold U.S. Treasury securities and residential
pass-through mortgages(7) issued by government-related entities Fannie Mae,
Freddie Mac and Ginnie Mae. We reinvested the proceeds in high-yield corporate
bonds and commercial mortgage-backed securities. In our view, high-yield debt
and commercial real estate had better prospects in an improving economy than
U.S. Treasury securities or agency residential mortgages. In addition, heavy
Treasury issuance and the end of the Federal Reserve's purchase program for
agency mortgage-backed securities weighed on security prices in these sectors.
The trades we made contributed positively to Fund performance.

The Fund also benefited during the reporting period from our relative-value
trading within investment-grade corporate bonds. Purchases were often funded
with sales of U.S. Treasury securities or sales of corporate bonds that had
achieved fair value. Examples of the former include purchases of Incitec Pivot
and CVS in a trade against Treasurys. An example of the latter was the purchase
of Williams Partners funded with sales of Sonat and Daimler Chrysler. As
mentioned earlier, we raised the Fund's allocation to the financials sector by
purchasing debt of regional banks, such as KeyBank and Regions Financial. These
trades were successful, as bank balance sheets strengthened.

Toward the end of the reporting period, we introduced Fund exposure to the
Korean won using currency forwards.


6. Duration is a measure of the price sensitivity of a fixed-income investment
   to changes in interest rates. Duration is expressed as a number of years and
   is considered a more accurate sensitivity gauge than average maturity.
7. Pass-through mortgages consist of a pool of residential mortgage loans, where
   homeowners' monthly payments of principal, interest and prepayments pass from
   the original bank through a government agency or investment bank to
   investors.

HOW DID THE FUND'S WEIGHTINGS CHANGE DURING THE REPORTING PERIOD?

We increased the Fund's allocations to investment-grade corporate bonds, high-
yield corporate bonds and commercial mortgage-backed securities during the
reporting period as we sought to boost yield and to align the Fund with more
robust demand for credit risk. The trades were funded with cash, sales of U.S.
Treasurys and sales of agency mortgage-backed securities. The trades also
modestly lengthened the Fund's duration.

HOW WAS THE FUND POSITIONED AT THE END OF THE REPORTING PERIOD?

As of April 30, 2010, the Fund was overweight relative to the Barclays Capital
U.S. Aggregate Bond Index in high-yield corporate bonds, investment-grade
corporate bonds, commercial mortgage-backed securities and asset-backed
securities. On the same date, the Fund was underweight relative to the benchmark
index in U.S. Treasurys, agency debentures and agency mortgage-backed
securities. Owing to stronger demand for risk assets, the Fund benefited from
underweight positions in government-related sectors and overweight positions in
credit-sensitive and commercial sectors.

30    MainStay Intermediate Term Bond Fund            The notes to the financial
statements are an integral part of, and should be read in conjunction with, the
financial statements.



NOTES TO FINANCIAL STATEMENTS UNAUDITED

NOTE 1--ORGANIZATION AND BUSINESS:

MainStay Funds Trust (the "Trust") is organized as a Delaware Statutory Trust
and is governed by a Declaration of Trust dated April 8, 2009. The Trust is
registered under the Investment Company Act of 1940, as amended (the "1940
Act"), as an open-end management investment company, and is comprised of twenty-
nine funds (collectively referred to as the "Funds"). These financial statements
and notes relate only to the MainStay Intermediate Term Bond Fund (the "Fund"),
a diversified fund. The Fund is the successor of the MainStay Intermediate Term
Bond Fund, a series of Eclipse Funds Inc. (the "Predecessor Fund"). The
reorganization of the Predecessor Fund with and into the Fund, which was not
subject to shareholder approval under applicable law, occurred on February 26,
2010. All information regarding and references to periods prior to the
commencement of operations of the Fund relate to the Predecessor Fund.

The Fund currently offers five classes of shares. Class I shares commenced
operations on January 2, 1991. Class A shares, Class B shares and Class C shares
commenced operations on January 2, 2004. Investor Class shares commenced
operations on February 28, 2008. Investor Class and Class A shares are offered
at net asset value ("NAV") per share plus an initial sales charge. No sales
charge applies on investments of $1 million or more (and certain other qualified
purchases) in Investor Class and Class A shares, but a contingent deferred sales
charge is imposed on certain redemptions of such shares within one year of the
date of purchase. Class B shares and Class C shares are offered at NAV without
an initial sales charge, although a declining contingent deferred sales charge
may be imposed on redemptions made within six years of purchase of Class B
shares and a 1.00% contingent deferred sales charge may be imposed on
redemptions made within one year of purchase of Class C shares. Class I shares
are offered at NAV and are not subject to a sales charge. Depending upon
eligibility, Class B shares convert to either Investor Class or Class A shares
eight years after the date they were purchased. Additionally, depending upon
eligibility, Investor Class shares may convert to Class A shares and Class A
shares may convert to Investor Class shares. The five classes of shares have the
same voting (except for issues that relate solely to one class), dividend,
liquidation and other rights, and the same terms and conditions, except that
Class B and Class C shares are subject to higher distribution and/or service fee
rates than Investor Class and Class A shares under a distribution plan pursuant
to Rule 12b-1 under the 1940 Act. Class I shares are not subject to a
distribution and/or service fee.

The Fund's investment objective is to seek to maximize total return, consistent
with liquidity, moderate risk to principal and investment in debt securities.

NOTE 2--SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with accounting
principles generally accepted in the United States of America ("GAAP") and
follows the significant accounting policies described below.

(A) SECURITIES VALUATION.  Debt securities are valued at prices supplied by a
pricing agent or broker selected by the Fund's Manager (as defined in Note 3(A))
in consultation with the Fund's Subadvisor, if any (as defined in Note 3(A)),
whose prices reflect broker/dealer supplied valuations and electronic data
processing techniques, if such prices are deemed by the Fund's Manager, in
consultation with the Fund's Subadvisor, if any, to be representative of market
values, at the regular close of trading of the New York Stock Exchange
("Exchange") (generally 4:00 p.m. Eastern time) on each day the Fund is open for
business ("valuation date"). Investments in other mutual funds are valued at
their NAVs as of the close of the Exchange on the valuation date.

Temporary cash investments acquired over 60 days prior to maturity are valued
using the latest bid prices or using valuations based on a matrix system (which
considers such factors as security prices, yields, maturities, and ratings),
both as furnished by independent pricing services. Other temporary cash
investments which mature in 60 days or less ("short-term investments") are
valued at amortized cost. The amortized cost method involves valuing a security
at its cost on the date of purchase and thereafter assuming a constant
amortization to maturity of the difference between the principal amount due at
maturity and cost.

Securities for which market quotations are not readily available are valued by
methods deemed in good faith by the Fund's Board to represent fair value. Equity
and non-equity securities which may be valued in this manner include, but are
not limited to: (i) a security the trading for which has been halted or
suspended; (ii) a debt security that has recently gone into default and for
which there is not a current market quotation; (iii) a security of an issuer
that has entered into a restructuring; (iv) a security that has been de-listed
from a national exchange; (v) a security the market price of which is not
available from an independent pricing source or, if so provided, does not, in
the opinion of the Fund's Manager or Subadvisor, as defined in Note 3(A),
reflect the security's market value; and (vi) a security where the trading on
that security's principal market is temporarily closed at a time when, under
normal conditions, it would be open. At April 30, 2010, the Fund held securities
with a value of $533,068 that were valued in such a manner.

Certain events may occur between the time that foreign markets close, on which
securities held by the Fund principally trade, and the time at which the Fund's
NAV is calculated. These events may include, but are not limited to, situations
relating to a single issuer in a market sector, significant fluctuations in U.S.
or foreign markets, natural

NOTES TO FINANCIAL STATEMENTS UNAUDITED (CONTINUED)


disasters, armed conflicts, governmental actions or other developments not tied
directly to the securities markets. Should the Manager or Subadvisor, as defined
in Note 3(A), conclude that such events may have affected the accuracy of the
last price reported on the local foreign market, the Manager or Subadvisor may,
pursuant to procedures adopted by the Fund's Board, adjust the value of the
local price to reflect the impact on the price of such securities as a result of
such events. Additionally, international equity securities are also fair valued
whenever the movement of a particular index exceeds certain thresholds. In such
cases, the securities are fair valued by applying factors provided by a third
party vendor in accordance with the Fund's policies and procedures. At April 30,
2010, certain foreign equity securities held by the Fund were fair valued.

"Fair value" is defined as the price that the Fund would receive upon selling an
investment in an orderly transaction to an independent buyer in the principal or
most advantageous market of the investment. Fair value measurements are
determined within a framework that has established a three-tier hierarchy which
maximizes the use of observable market data and minimizes the use of
unobservable inputs to establish classification of fair value measurements for
disclosure purposes. "Inputs" refer broadly to the assumptions that market
participants would use in pricing the asset or liability, including assumptions
about risk, such as the risk inherent in a particular valuation technique used
to measure fair value using a pricing model and/or the risk inherent in the
inputs for the valuation technique. Inputs may be observable or unobservable.
Observable inputs are inputs that reflect the assumptions market participants
would use in pricing the asset or liability based on market data obtained from
sources independent of the reporting entity. Unobservable inputs are inputs that
reflect the reporting entity's own assumptions about the assumptions market
participants would use in pricing the asset or liability developed based on the
information available in the circumstances. The inputs or methodology used for
valuing securities may not be an indication of the risks associated with
investing in those securities. The three-tier hierarchy of inputs is summarized
in the three broad Levels listed below.

- - Level 1--quoted prices in active markets for identical investments

- - Level 2--other significant observable inputs (including quoted prices for
  similar investments in active markets, interest rates and yield curves,
  prepayment speeds, credit risks, etc.)

- - Level 3--significant unobservable inputs (including the Fund's own assumptions
  about the assumptions that market participants would use in determining the
  fair value of investments)

The aggregate value by input level, as of April 30, 2010, for the Fund's
investments is included at the end of the Fund's Portfolio of Investments.

The valuation techniques used by the Fund to measure fair value during the six-
month period ended April 30, 2010 maximized the use of observable inputs and
minimized the use of unobservable inputs. The Fund may have utilized some of the
following fair value techniques: multi-dimensional relational pricing models,
option adjusted spread pricing and estimating the price that would have
prevailed in a liquid market for an international equity security given
information available at the time of evaluation, when there are significant
events after the close of local foreign markets. For the six-month period ended
April 30, 2010, there have been no changes to the fair value methodologies.

Generally, a security is considered illiquid if it cannot be sold or disposed of
in the ordinary course of business at approximately the price at which it is
valued. Its illiquidity might prevent the sale of such security at a time when
the Manager or Subadvisor, if any, as defined in Note 3(A) might wish to sell,
and these securities could have the effect of decreasing the overall level of a
Fund's liquidity. Further, the lack of an established secondary market may make
it more difficult to value illiquid securities, requiring the Fund to rely on
judgments that may be somewhat subjective in determining value, which could vary
from the amount that the Fund could realize upon disposition. Difficulty in
selling illiquid securities may result in a loss or may be costly to the Fund.
Under the supervision of the Board, the Manager or Subadvisor, if any,
determines the liquidity of a Fund's investments; in doing so, the Manager or
Subadvisor, if any, may consider various factors, including (1) the frequency of
trades and quotations, (2) the number of dealers and prospective purchasers, (3)
the dealer undertakings to make a market, and (4) the nature of the security and
the market in which it trades (e.g., the time needed to dispose of the security,
the method of soliciting offers and the mechanics of transfer). Illiquid
securities generally will be valued in such manner, as the Board in good faith
deems appropriate to reflect their fair market value.

(B) FEDERAL INCOME TAXES.  The Fund's policy is to comply with the requirements
of the Internal Revenue Code of 1986, as amended (the "Internal Revenue Code")
applicable to regulated investment companies and to distribute all of the
taxable income to the shareholders of the Fund within the allowable time limits.
Therefore, no federal income tax provision is required.

Management evaluates its tax positions to determine if the tax positions taken
meet the minimum recognition threshold in connection with accounting for
uncertainties in income tax positions taken or expected to be taken for the
purposes of measuring and recognizing tax liabilities in the financial
statements. Recognition of tax benefits of an uncertain tax position is required
only when the position is


32    MainStay Intermediate Term Bond Fund



"more likely than not" to be sustained assuming examination by taxing
authorities. Management has analyzed the Fund's tax positions taken on federal
income tax returns for all open tax years (current and prior three tax years),
and has concluded that no provision for federal income tax is required in the
Fund's financial statements. The Fund's federal and state income and federal
excise tax returns for tax years for which the applicable statutes of
limitations have not expired are subject to examination by the Internal Revenue
Service and state departments of revenue.

(C) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS.  Dividends and distributions
are recorded on the ex-dividend date. The Fund intends to declare and pay
dividends of net investment income monthly and distributions of net realized
capital and currency gains, if any, annually, Unless the shareholder elects
otherwise, all dividends and distributions are reinvested in the same class of
shares of the Fund, at NAV. Dividends and distributions to shareholders are
determined in accordance with federal income tax regulations and may differ from
GAAP.

(D) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  The Fund records security
transactions on the trade date. Realized gains and losses on security
transactions are determined using the identified cost method and include gains
and losses from repayments of principal on mortgage-backed securities. Interest
income is accrued as earned using the effective interest rate method. Discounts
and premiums on securities purchased, other than short-term investments, for the
Fund are accreted and amortized, respectively, on the effective interest rate
method over the life of the respective securities or, in the case of a callable
security, over the period to the first date of call. Discounts and premiums on
short-term investments are accreted and amortized, respectively, on the
straight-line method. Income from payment-in-kind securities is recorded daily
based on the effective interest method of accrual.

Investment income and realized and unrealized gains and losses on investments of
the Fund are allocated to separate classes of shares pro rata based upon their
relative net assets on the date the income is earned or realized and unrealized
gains and losses are incurred.

(E) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred, except where direct allocations of expenses can be made. Expenses
(other than transfer agent expenses and fees incurred under the shareholder
services plans and the distribution plans further discussed in Note 3(B)) are
allocated to separate classes of shares pro rata based upon their relative NAV
on the date the expenses are incurred. The expenses borne by the Fund, including
those of related parties to the Fund, are shown in the Statement of Operations.

(F) USE OF ESTIMATES.  In preparing financial statements in conformity with
GAAP, management makes estimates and assumptions that affect the reported
amounts and disclosures in the financial statements. Actual results could differ
from those estimates.

(G) REPURCHASE AGREEMENTS.  The Fund may enter into repurchase agreements to
earn income. The Fund may enter into repurchase agreements only with financial
institutions that are deemed by the Manager or Subadvisor to be creditworthy,
pursuant to guidelines established by the Fund's Board. Repurchase agreements
are considered under the 1940 Act to be collateralized loans by a Fund to the
seller secured by the securities transferred to the Fund.

When the Fund invests in repurchase agreements, the Fund's custodian takes
possession of the collateral pledged for investments in such repurchase
agreements. The underlying collateral is valued daily on a mark-to-market basis
to determine that the value, including accrued interest, exceeds the repurchase
price. In the event of the seller's default of the obligation to repurchase, the
Fund has the right to liquidate the collateral and apply the proceeds in
satisfaction of the obligation. Under certain circumstances, in the event of
default or bankruptcy by the other party to the agreement, realization and/or
retention of the collateral may be subject to legal proceedings and possible
realized loss to the Fund.

(H) FUTURES CONTRACTS.  A futures contract is an agreement to purchase or sell a
specified quantity of an underlying instrument at a specified future date and
price, or to make or receive a cash payment based on the value of a financial
instrument (e.g., foreign currency, interest rate, security, or securities
index.) The Fund is subject to interest rate risk in the normal course of
investing in these transactions. During the period the futures contract is open,
changes in the value of the contract are recognized as unrealized gains or
losses by "marking to market" such contract on a daily basis to reflect the
market value of the contract at the end of each day's trading. The Fund agrees
to receive from or pay to the broker an amount of cash equal to the daily
fluctuation in the value of the contract. Such receipts or payments are known as
"variation margin". When the futures contract is closed, the Fund records a
realized gain or loss equal to the difference between the proceeds from (or cost
of) the closing transaction and the Fund's basis in the contract.

The use of futures contracts involves, to varying degrees, elements of market
risk in excess of the amount recognized in the Statement of Assets and
Liabilities. The contract or notional amounts and variation margin reflect the
extent of the Fund's involvement in open futures positions. Risks arise from the
possible imperfect correlation in movements in the price of futures contracts,
interest rates and the underlying hedged assets, and the possible inability of
counterparties to meet the terms of their contracts. However, the Fund's
activities in futures contracts have minimal

                                                   mainstayinvestments.com    33



NOTES TO FINANCIAL STATEMENTS UNAUDITED (CONTINUED)


counterparty risk as they are conducted through regulated exchanges that
guarantee the futures against default by the counterparty. The Fund invests in
futures contracts to help manage the duration and yield curve of the portfolio
while minimizing the exposure to wider bid/ask spreads in traditional bonds. The
Fund's investment in futures contracts and other derivatives may increase the
volatility of the Fund's NAV and may result in a loss to the Fund.

(I) FOREIGN CURRENCY FORWARD CONTRACTS.  The Fund may enter into foreign
currency forward contracts, which are agreements to buy or sell currencies of
different countries on a specified future date at a specified rate. The Fund is
subject to foreign currency exchange rate risk in the normal course of investing
in these transactions. During the period the forward contract is open, changes
in the value of the contract are recognized as unrealized gains or losses by
"marking to market" such contract on a daily basis to reflect the market value
of the contract at the end of each day's trading. Cash movement occurs on
settlement date. When the forward contract is closed, the Fund records a
realized gain or loss equal to the difference between the proceeds from (or cost
of) the closing transaction and the Fund's basis in the contract. The Fund
enters into foreign currency forward contracts to reduce currency risk versus
the benchmark or for trade settlement.

The use of foreign currency forward contracts involves, to varying degrees,
elements of market risk in excess of the amount recognized in the Statement of
Assets and Liabilities. The contract amount reflects the extent of the Fund's
involvement in these financial instruments. Risks arise from the possible
movements in the foreign exchange rates underlying these instruments. While a
Fund may enter into forward contracts to reduce currency exchange risks, changes
in currency exchange rates may result in poorer overall performance for the Fund
than if it had not engaged in such transactions. Exchange rate movements can be
large, depending on the currency, and can last for extended periods of time,
affecting the value of the Fund's assets. Moreover, there may be an imperfect
correlation between the Fund's holdings of securities denominated in a
particular currency and forward contracts entered into by the Fund. Such
imperfect correlation may prevent the Fund from achieving the intended hedge or
expose the Fund to the risk of currency exchange loss. The unrealized
appreciation (depreciation) on forward contracts reflects the Fund's exposure at
valuation date to credit loss in the event of a counterparty's failure to
perform its obligations. (See Note 5.)

(J) MORTGAGE DOLLAR ROLLS.  The Fund may enter into mortgage dollar roll ("MDR")
transactions in which it sells mortgage-backed securities ("MBS") from its
portfolio to a counterparty from whom it simultaneously agrees to buy a similar
security on a delayed delivery basis. The MDR transactions of the Fund are
classified as purchase and sale transactions. The securities sold in connection
with the MDRs are removed from the portfolio and a realized gain or loss is
recognized. The securities the Fund has agreed to acquire are included at market
value in the Portfolio of Investments and liabilities for such purchase
commitments are included as payables for investments purchased. During the roll
period, the Fund foregoes principal and interest paid on the securities. The
Fund is compensated by the difference between the current sales price and the
forward price for the future as well as by the earnings on the cash proceeds of
the initial sale. MDRs may be renewed without physical delivery of the
securities subject to the contract. The Fund maintains liquid assets from its
portfolio having a value not less than the repurchase price, including accrued
interest. MDR transactions involve certain risks, including the risk that the
MBS returned to the Fund at the end of the roll, while substantially similar,
could be inferior to what was initially sold to the counterparty.

(K) SECURITIES LENDING.  In order to realize additional income, the Fund may
engage in securities lending, subject to the limitations set forth in the 1940
Act, and relevant guidance by the staff of the Securities and Exchange
Commission. In the event the Fund does engage in securities lending, the Fund
will lend through its custodian, State Street Bank and Trust Company ("State
Street"). State Street will manage the Fund's cash collateral in accordance with
the Lending Agreement between the Fund and State Street, and indemnify the
Fund's portfolio against counterparty risk. The loans will be collateralized by
cash or securities at least equal at all times to the market value of the
securities loaned. Collateral will consist of U.S. Government securities, cash
equivalents or irrevocable letters of credit. The Fund may bear the risk of
delay in recovery of, or loss of rights in, the securities loaned should the
borrower of the securities experience financial difficulty. The Fund may also
record realized gain or loss on securities deemed sold due to a borrower's
inability to return securities on loan. The Fund will receive compensation for
lending its securities in the form of fees or retain a portion of interest on
the investment of any cash received as collateral. The Fund also will continue
to receive interest and dividends on the securities loaned and any gain or loss
in the market price of the securities loaned that may occur during the term of
the loan will be for the account of the Fund.

Although the Fund and New York Life Investments (as defined in Note 3(A)) have
temporarily suspended securities lending, the Fund and New York Life Investments
reserve the right to reinstitute lending when deemed appropriate. The Fund had
no portfolio securities on loan as of April 30, 2010.

(L) CONCENTRATION OF RISK.  The Fund invests in foreign securities, which carry
certain risks that are in addition to the usual risks inherent in domestic
instruments. These risks include those resulting from currency fluctuations,
future adverse political and economic developments and possible imposition of
currency exchange blockages or


34    MainStay Intermediate Term Bond Fund



other foreign governmental laws or restrictions. These risks are likely to be
greater in emerging markets than in developed markets. The ability of issuers of
debt securities held by the Fund to meet their obligations may be affected by
economic or political developments in a specific country, industry or region.

(M) INDEMNIFICATIONS.  Under the Trust's organizational documents, its officers
and trustees are indemnified against certain liabilities that may arise out of
performance of their duties to the Trust. Additionally, in the normal course of
business, the Fund enters into contracts with third-party service providers that
contain a variety of representations and warranties and which provide general
indemnifications. The Fund's maximum exposure under these arrangements is
unknown, as this would involve future claims that may be made against the Fund
that have not yet occurred. Based on experience, management is of the view that
the risk of loss in connection with these potential indemnification obligations
is remote. However, there can be no assurance that material liabilities related
to such obligations will not arise in the future, which could adversely impact
the Fund.

(N) QUANTITATIVE DISCLOSURE OF DERIVATIVE HOLDINGS.  The following tables show
additional disclosures about the Fund's derivative and hedging activities,
including how such activities are accounted for and their effect on the Fund's
financial positions, performance and cash flows. These derivatives are not
accounted for as hedging instruments.

NOTE 3--FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER AND SUBADVISOR.  New York Life Investment Management LLC ("New York
Life Investments" or "Manager"), a registered investment adviser and an
indirect, wholly-owned subsidiary of New York Life Insurance Company ("New York
Life"), serves as the Fund's Manager, pursuant to a Management Agreement, as
amended ("Management Agreement"). The Manager provides offices, conducts
clerical, recordkeeping and bookkeeping services, and keeps most of the
financial and accounting records required to be maintained by the Fund. Except
for the portion of salaries and expenses that are the responsibility of the
Fund, the Manager also pays the salaries and expenses of all personnel
affiliated with the Fund and the operational expenses of the Fund. MacKay
Shields LLC (the "Subadvisor"), a registered investment adviser and an indirect,
wholly-owned subsidiary of New York Life, serves as Subadvisor to the Fund and
is responsible for the day-to-day portfolio management of the Fund. Pursuant to
the terms of a Subadvisory Agreement between New York Life Investments and the
Subadvisor, New York Life Investments pays for the services of the Subadvisor.

The Fund pays the Manager a monthly fee for services performed and facilities
furnished at an annual rate of the Fund's average daily net assets as follows:
0.60% on assets up to $500 million, 0.575% on assets from $500 million to $1
billion, and 0.55% on assets in excess of $1 billion. Effective on September 11,
2009, New York Life Investments has contractually agreed to waive a portion of
its management fee so that it does not exceed 0.50% on assets up to $1 billion
and 0.475% on assets in excess of $1 billion. The effective management fee rate
(exclusive of any applicable waivers/reimbursements) was 0.60% for the six-month
period ended April 30, 2010.

Effective on September 11, 2009, New York Life Investments had agreed to limit
total ordinary operating expenses (total ordinary operating expenses excludes
taxes, interest, litigation, extraordinary expenses, brokerage, and other
transaction expenses relating to the purchase or sale of portfolio investments
and the fees and expenses of any other fund in which the fund invests) of Class
I shares to 0.50% through November 27, 2009 and to 0.60% thereafter. This
agreement also requires the Manager to waive a portion of the management fee in
addition to the management fee described above or other non-class specific
expenses or Investor Class, Class A, Class B and Class C shares to the extent
necessary in order to maintain the expense limitation applicable to Class I
shares. This agreement expires on February 28, 2011 and is reviewed annually by
the Board in connection with its review of the Fund's investment advisory
agreements. Based on its review, the Board may agree to maintain, modify of
terminate the agreement.

For the six-month period ended April 30, 2010, New York Life Investments earned
fees from the Fund in the amount of $1,723,579 and waived/reimbursed its fees in
the amount of $503,767.

State Street, 1 Lincoln Street, Boston, Massachusetts 02111, provides sub-
administration and sub-accounting services to the Fund pursuant to an agreement
with New York Life Investments. These services include calculating the daily
NAVs of the Fund, maintaining the general ledger and sub-ledger accounts for the
calculation of the Fund's respective NAVs, and assisting New York Life
Investments in conducting various aspects of the Fund's administrative
operations. For providing these services to the Fund, State Street is
compensated by New York Life Investments.

(B) DISTRIBUTION AND SERVICE FEES.  The Trust, on behalf of the Fund, has
entered into a Distribution Agreement with NYLIFE Distributors LLC (the
"Distributor"), an indirect, wholly-owned subsidiary of New York Life. The Fund
has adopted distribution plans, (the "Plans") in accordance with the provisions
of Rule 12b-1 under the 1940 Act.

Pursuant to the Investor Class and Class A Plans, the Distributor receives a
monthly distribution fee from the Investor Class and Class A shares at an annual
rate of 0.25% of the average daily net assets of the Investor Class and Class A
shares for distribution or service activities as designated by the Distributor.
Pursuant to the Class B and Class C


36    MainStay Intermediate Term Bond Fund



Plans, Class B and Class C shares of the Fund pay the Distributor a monthly
distribution fee at an annual rate of 0.75% of the average daily net assets of
the Fund's Class B and Class C shares, along with a service fee at an annual
rate of 0.25% of the average daily net assets of the Class B and Class C shares
of the Fund for a total 12b-1 fee of 1.00%. Class I shares are not subject to a
distribution or service fee.

The Plans provide that the distribution and service fees are payable to the
Distributor regardless of the amounts actually expended by the Distributor for
distribution of the Fund's shares and service activities.

(C) SALES CHARGES.  The Fund was advised by the Distributor that the amount of
sales charges retained on sales of Investor Class and Class A shares were $2,570
and $13,769, respectively, for the six-month period ended April 30, 2010. The
Fund was also advised that the Distributor retained contingent deferred sales
charges on redemptions of Class A, Class B and Class C shares of $62, $5,903 and
$1,943, respectively, for the six-month period ended April 30, 2010.

(D) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT.  NYLIM
Service Company LLC, an affiliate of New York Life Investments, is the Fund's
transfer, dividend disbursing and shareholder servicing agent pursuant to an
agreement between NYLIM Service Company LLC and the Trust. NYLIM Service Company
LLC has entered into an agreement with Boston Financial Data Services, Inc.
("BFDS") pursuant to which BFDS performs certain transfer agent services on
behalf of NYLIM Service Company LLC. Transfer agent expenses incurred by the
Fund for the six-month period ended April 30, 2010, were as follows:

<Table>

- -----------------------------------------------

</Table>


(E) SMALL ACCOUNT FEE.  Shareholders with small accounts adversely impact the
cost of providing transfer agency services. In an effort to reduce total
transfer agency expenses, the Fund has implemented a small account fee on
certain types of accounts. Certain shareholders with an account balance of less
than $1,000 are charged an annual per account fee of $20 (assessed semi-
annually). These fees are included in transfer agent fees shown on the Statement
of Operations.

(F) CAPITAL.  At April 30, 2010, New York Life and its affiliates beneficially
held shares of the Fund with the following values and percentages of net assets
as follows:

<Table>

(G) OTHER.  Pursuant to the Management Agreement, a portion of the cost of legal

Life Investments is payable directly by the Fund. For the six-month period ended
April 30, 2010, these fees, which are included in professional fees shown on the
Statement of Operations, were $14,580.

NOTE 4--FEDERAL INCOME TAX:

At October 31, 2009, for federal income tax purposes, capital loss carryforwards
of $6,007,340 were available as shown in the table below, to the extent provided
by the regulations to offset future realized gains of the Fund through the years
indicated. The fund acquired $6,153,939 of capital losses in its reorganization
with the MainStay Institutional Bond Fund (See Note 10); use of these losses may
be limited due to the provisions of IRC Section 382. To the extent that these
loss carryforwards are used to offset future capital gains, it is probable that
the capital gains so offset will not be distributed to shareholders. No capital
gain distributions shall be made until any capital loss carryforwards have been
fully utilized or expired.

is an annual rate of 0.10% of the average commitment amount, plus a 0.04% up-
front payment payable, regardless of usage, to The Bank of New York Mellon,

NOTE 10-- FUND ACQUISITION:

At a meeting held on April 18, 2009, the Board of Trustees approved a plan of
reorganization whereby the Fund would acquire the assets, including the
investments, and assume the liabilities of MainStay Institutional Bond Fund, a
series of The MainStay Funds. Shareholders of the MainStay Institutional Bond
Fund approved this reorganization on October 5, 2009, which was then completed
on October 16, 2009. The aggregate net assets of the Fund immediately before the
acquisition were $264,046,943 and the combined net assets after the acquisition
were $519,435,233.

The acquisition was accomplished by a tax-free exchange of the following:

NOTE 11--NEW ACCOUNTING PRONOUNCEMENT:

In January 2010, the Financial Accounting Standards Board ("FASB") issued
Accounting Standards Update ("ASU") No. 2010-06 "Improving Disclosures about
Fair Value Measurements". ASU 2010-06 requires reporting entities to make new
disclosures about amount and reasons for significant transfers in and out of
Level 1 and Level 2 fair value measurements and input and valuation techniques
used to measure fair value for both recurring and nonrecurring fair value
measurements that fall in either Level 2 or Level 3, and information on
purchased, sales, issuances, and settlements in the roll forward of activity in
Level 3 fair value measures. The new and revised disclosure requirements are
effective for interim and annual reporting periods beginning after December 15,
2009 except for the disclosures about purchased, sales, issuances, and
settlements in the roll forward of activity in Level 3 fair value measures,
which are effective for fiscal years beginning after December 15, 2010. As of
April 30, 2010, the Fund has adopted ASU 2010-06. The adoption of ASU 2010-06
has not impacted the amounts reported in the financial statements; however,
there are additional disclosures in the Portfolio of Investments.

NOTE 12--SUBSEQUENT EVENTS:

In connection with the preparation of the financial statements of the Fund as of
and for the fiscal six-month period ended April 30, 2010, events and
transactions subsequent to April 30, 2010 through the date the financial
statements were issued have been evaluated by the Fund's management for possible
adjustment and/or disclosure. No subsequent events requiring financial statement
adjustment or disclosure have been identified.

        MESSAGE FROM THE PRESIDENT AND SEMIANNUAL REPORT

        Unaudited - April 30, 2010

        MainStay Retirement 2010 Fund
        MainStay Retirement 2020 Fund
        MainStay Retirement 2030 Fund
        MainStay Retirement 2040 Fund
        MainStay Retirement 2050 Fund



        MESSAGE FROM THE PRESIDENT

During the six months ended April 30, 2010, stock and bond markets generally
advanced, despite some volatility in January and February. Domestic small-cap
stocks were particularly strong, and U.S. stocks at all capitalization levels
provided double digit returns. Value stocks outpaced growth stocks for companies
of all sizes during the reporting period.

International stocks provided positive returns overall, but results varied
widely by country. Concerns about Greece's ability to meet its debt obligations
led many investors to abandon their holdings in Greece and question their
investments in several peripheral European nations where perceived risk had
increased. For the six-month reporting period, equities in the Far East
(including Japan) tended to be stronger than those in Europe.

The economic recovery in the United States continued. Real gross domestic
product advanced in the first quarter of 2010, though at a slower pace than in
the fourth quarter of 2009. The Federal Open Market Committee kept the targeted
federal funds rate at a historically low level throughout the reporting period,
which prompted many investors to leave the safety of U.S. Treasury securities in
search of higher yield.

In the high-yield bond market, lower-rated credits tended to be the strongest
performers. With investment-grade investors crossing into high-yield territory,
however, the highest-rated high-yield credits also saw strong demand. In the
municipal market, new-issue supply was reduced by government incentives that
encouraged municipal issuers to raise funds in the taxable market. In the
leveraged-loan market, new issuance strengthened, but extensive repayments
caused the market as a whole to contract.


Throughout the six-month reporting period, MainStay's portfolio managers sought
to make the most of market conditions within the investment strategies and risk
parameters of their respective Funds. While individual markets and Fund results
may vary, our pursuit of competitive returns over full market cycles has never
changed.

The information that follows provides a closer look
at the securities, strategies and market conditions that affected your MainStay
Fund(s) during the six months ended April 30, 2010. Of course, past performance
is no guarantee of future results. Even in a rising market, we believe that
maintaining a long-term perspective can be valuable. At MainStay, we believe
that in all markets, broad diversification, gradual allocation adjustments and
regular portfolio reviews can help guide you toward your long-range financial
goals.

We thank you for choosing MainStay Funds, and we look forward to serving your
investment needs for many years to come.

Sincerely,

/s/ STEPHEN P. FISHER

Stephen P. Fisher
President

   of $100,000 or more invested in any share classes of any of the MainStay
   Funds, the minimum initial investment is $15,000. Investor Class shares and
   Class A shares are sold with a maximum initial sales charge of 5.50%, no
   contingent deferred sales charge ("CDSC") and an annual 12b-1 fee of 0.25%.
   Class I shares are sold with no initial sales charge or CDSC, have no annual

6    MainStay Retirement 2010 Fund



COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY RETIREMENT 2010 FUND
(UNAUDITED)
- --------------------------------------------------------------------------------

The example below is intended to describe the fees and expenses borne by
shareholders during the six-month period from November 1, 2009, to April 30,
2010, and the impact of those costs on your investment.

EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, exchange fees, and sales charges (loads) on
purchases (as applicable), and (2) ongoing costs, including management fees,
distribution and/or service (12b-1) fees, and other Fund expenses (as
applicable). This example is intended to help you understand your ongoing costs
(in dollars) of investing in the Fund and to compare these costs with the
ongoing costs of investing in other mutual funds. The example is based on an
investment of $1,000 made at the beginning of the six-month period and held for
the entire period from November 1, 2009, to April 30, 2010.

This example illustrates your Fund's ongoing costs in two ways:

- - ACTUAL EXPENSES
The second and third data columns in the table below provide information about
actual account values and actual expenses. You may use the information in these
columns, together with the amount you invested, to estimate the expenses that
you paid during the six-months ended April 30, 2010. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number under the heading entitled "Expenses Paid
During Period" to estimate the expenses you paid on your account during this
period.

- - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The fourth and fifth data columns in the table below provide information about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense ratio and an assumed rate of return of 5% per year before expenses,
which is not the Fund's actual return. The hypothetical account values and
expenses may not be used to estimate the actual ending account balances or
expenses you paid for the six-month period shown. You may use this information
to compare the ongoing costs of investing in the Fund with the ongoing costs of
investing in other Funds. To do so, compare this 5% hypothetical example with
the 5% hypothetical examples that appear in the shareholder reports of the other
Funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as
redemption fees, if applicable, exchange fees, or sales charges (loads).
Therefore, the fourth and fifth data columns of the table are useful in
comparing ongoing costs only and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.

1. Expenses are equal to the Fund's annualized expense ratio of each class
   (0.47% for Investor Class, 0.37% for Class A, 0.12% for Class I, 0.47% for
   Class R2 and 0.72% for Class R3) multiplied by the average account value over
   the period, divided by 365 and multiplied by 181 (to reflect the one-half
   year period). The table above represents the actual expenses incurred during
   the one-half year period. In addition to the fees and expenses which the Fund
   bears directly, the Fund indirectly bears a pro rata share of the fees and
   expenses of the Underlying Funds in which it invests. Such indirect expenses
   are not included in the above-reported expense figures.

8    MainStay Retirement 2010 Fund



PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

QUESTIONS ANSWERED BY PORTFOLIO MANAGERS TONY ELAVIA AND JONATHAN SWANEY OF
MADISON SQUARE INVESTORS LLC, THE FUND'S SUBADVISOR.

HOW DID MAINSTAY RETIREMENT 2010 FUND PERFORM RELATIVE TO ITS PEERS AND ITS
BENCHMARK DURING THE SIX MONTHS ENDED APRIL 30, 2010?

Excluding all sales charges, MainStay Retirement 2010 Fund returned 7.99% for
Investor Class shares and 8.04% for Class A shares for the six months ended
April 30, 2010. Over the same period, the Fund's Class I shares returned 8.09%,
Class R2 shares returned 8.01% and Class R3 shares returned 7.75%. All share
classes underperformed the 8.30% return of the average Lipper(1) mixed-asset
target 2010 fund and the 15.66% return of the S&P 500(R) Index(2) for the six
months ended April 30, 2010. As of April 30, 2010, Class R1 shares had not
commenced investment operations. The S&P 500(R) Index is the Fund's broad-based
securities-market index. See page 5 for Fund returns with sales charges.

WHAT FACTORS CONTRIBUTED TO THE FUND'S RELATIVE PERFORMANCE DURING THE REPORTING
PERIOD?

The Fund invests in other mutual funds referred to as Underlying Funds. The
Underlying Funds may invest in fixed-income securities or in domestic or
international stocks at various capitalization levels. The Fund's primary
benchmark, on the other hand, consists entirely of U.S. large-cap stocks. These
asset-class differences accounted for much of the Fund's underperformance of the
S&P 500(R) Index. Even with the Fund's asset-allocation targets taken into
account, however, the Fund's performance was modestly below our expectations.
Disappointing results from several Underlying Funds, particularly those that use
quantitative stock selection, detracted from the Fund's performance relative to
the S&P 500(R) Index and the Fund's average Lipper peer fund. The Fund also had
negative beta exposure (or lower volatility than the market as a whole) in a
period when the stock market was rising. In addition, the Fund suffered from a
slight bias toward growth-oriented stocks in a period when value stocks were in
favor.

DURING THE REPORTING PERIOD, HOW DID YOU DETERMINE THE FUND'S ALLOCATIONS AMONG
THE UNDERLYING FUNDS?

In managing the Fund, we considered a variety of information, including
portfolio-level characteristics of the Underlying Funds, such as capitalization,
style biases and sector exposures. We also examined the attributes of the
Underlying Funds' holdings,
such as valuation metrics, earnings data and technical indicators. Finally, we
evaluated the historical success of the portfolio managers responsible for the
Underlying Funds. In general, we sought Underlying Equity Funds that had a track
record of capable portfolio management, that occupied attractively valued market
segments and that invested in companies with fairly priced securities and strong
price and earnings momentum. During the reporting period, these techniques were
generally unsuccessful, as they steered the Fund into Underlying Funds that
collectively underperformed the S&P 500(R) Index after adjusting for Underlying
Fund expenses and the Fund's strategic allocation policy.

Underlying Fixed Income Funds were selected based upon the type and country of
issuance of the securities in which they invested, the average credit quality of
those securities and their duration.(3)

It is usually difficult to identify any single factor that had a
disproportionate effect on the Fund's relative performance, but during the
reporting period, one theme had a distinctive impact. We tilted the Fund toward
Underlying Funds that prized earnings stability, because higher-quality stocks
with stable earnings have historically been rewarded with higher returns than
lower-quality stocks with earnings that are less stable. Unfortunately, when the
global equity markets turned positive in the spring of 2009, investors
aggressively bought the riskiest and lowest-quality securities in anticipation
that these securities would benefit most from a recovery. This trend persisted
throughout the reporting period, and stocks with negative earnings and cash
flows were among the best performers. This so-called junk rally served as a
significant drag on the Fund's relative performance during the reporting period.

DID YOU MAKE ANY SIGNIFICANT CHANGES IN THE FUND'S ALLOCATIONS DURING THE
REPORTING PERIOD?

The most noteworthy change we made during the reporting period was a gradual,
protracted shift away from large-cap growth-oriented Underlying Funds toward
Underlying Funds with a more neutral style and capitalization focus.
Specifically, we reduced the Fund's allocations to MainStay Large Cap Growth
Fund, MainStay Growth Equity Fund and MainStay 130/30 Growth Fund and increased
the Fund's allocations to MainStay Epoch U.S. All Cap Fund and, to a lesser
degree, to MainStay 130/30 Core Fund. This shift had a positive impact on the
Fund's performance, as value-oriented small-capitalization stocks

3. Duration is a measure of the price sensitivity of a fixed-income investment
   to changes in interest rates. Duration is expressed as a number of years and
   is considered a more accurate sensitivity gauge than average maturity.

outpaced growth-oriented larger-cap stocks as the reporting period progressed.
We have substantially reduced the Fund's exposure to growth-oriented stocks over
the past two and a half years. At the end of the current reporting period, the
Fund was evenly positioned between growth and value.

In addition, we reduced the Fund's allocations to MainStay Indexed Bond Fund and
MainStay Intermediate Term Bond Fund and directed the proceeds to Underlying
Fixed Income Funds that focus on inflation indexed Treasury bonds. This decision
had a very modest positive impact on the Fund's performance.

During the reporting period, the Fund initiated new positions in Columbia Small
Cap Index Fund, MainStay Epoch Global Choice Fund and MainStay Convertible Fund.
We selected Columbia Small Cap Index Fund to gain pure exposure to the small-cap
segment of the U.S. stock market. We chose MainStay Epoch Global Choice Fund to
further diversify the Fund across management strategies and to enhance the
Fund's exposure to desirable cash flow metrics. MainStay Convertible Fund was
chosen to increase the Fund's responsiveness to movements in the equity market
while incrementally lowering the Fund's average credit quality and duration.

DURING THE REPORTING PERIOD, WHICH UNDERLYING EQUITY FUND POSITIONS HAD THE
HIGHEST TOTAL RETURNS AND WHICH HAD THE LOWEST TOTAL RETURNS?

Columbia Small Cap Index Fund, MainStay U.S. Small Cap Fund and MainStay Epoch
U.S. All Cap Fund generated the best total returns among the Underlying Equity
Funds in which the Fund invested, as these Underlying Funds invested most
heavily in smaller-capitalization stocks. The worst returns came from Underlying
Equity Funds that invest abroad, namely MainStay ICAP International Fund,
MainStay 130/30 International Fund and MainStay International Equity Fund. These
Underlying Funds were hampered not only by comparatively weak overseas returns
in local currencies but also by a strengthening U.S. dollar.


DURING THE REPORTING PERIOD, WHICH UNDERLYING EQUITY FUNDS MADE THE STRONGEST
CONTRIBUTIONS TO THE FUND'S ABSOLUTE PERFORMANCE AND WHICH UNDERLYING EQUITY
FUNDS DETRACTED THE MOST?

On an absolute basis, the strongest contributions to the Fund's equity
performance came from the Fund's largest Underlying Equity Fund holdings, namely
MainStay MAP Fund and MainStay Growth Equity Fund.

During the reporting period, no Underlying Equity Funds in which the Fund
invested provided negative returns. The weakest contributions to the Fund's
performance came from two of its smallest positions, MainStay S&P 500 Index Fund
and MainStay Epoch Global Choice Fund.

WHAT FACTORS INFLUENCED PERFORMANCE IN THE FIXED-INCOME PORTION OF THE FUND?

U.S. Treasury yields were largely unchanged over the course of the reporting
period. Signs of economic strength, improving corporate profitability and a
large supply of new issuance threatened to push rates higher. These factors,
however, were offset by concerns about corporate and sovereign default risk
(holding company Dubai World and Greece were notable examples) and by questions
about the sustainability of the economic recovery. Lower-quality fixed-income
securities generally outperformed higher-quality fixed-income securities as
credit spreads(4) narrowed, driving bond prices higher.

HOW DID THE FUND ALLOCATE ASSETS AMONG THE UNDERLYING FIXED INCOME FUNDS DURING
THE REPORTING PERIOD?

In anticipation that Treasury rates would ultimately rise and that credit
spreads would continue to narrow from the wider-than-normal levels we had
observed, we shortened the Fund's duration and reestablished a bias toward
lower-quality instruments. We implemented these strategies primarily by
increasing the Fund's holdings in MainStay Floating Rate Fund, MainStay High
Yield Opportunities Fund and MainStay High Yield Corporate Bond Fund.



4. The terms "credit spread" and "yield spread" may refer to the difference in
   yield between a security or type of security and comparable U.S. Treasury
   issues. The terms may also refer to the difference in yield between two
   specific securities or types of securities at a given time.

10    MainStay Retirement 2010 Fund



WHICH UNDERLYING FIXED INCOME FUNDS HAD THE STRONGEST ABSOLUTE PERFORMANCE
DURING THE REPORTING PERIOD AND WHICH ONES DETRACTED FROM THE FUND'S ABSOLUTE
PERFORMANCE?

The Fund's best-performing Underlying Fixed Income Fund holdings were MainStay
High Yield Opportunities Fund and MainStay High Yield Corporate Bond Fund, both
of which benefited from the contraction in credit spreads that accompanied the
economic recovery. The worst-performing Underlying Fixed Income Fund--and the
only Fund holding that provided a negative return--was American Century
International Bond Fund. This Underlying Fund was hurt by the potential for
sovereign defaults and by a rising U.S. dollar.

1. Performance tables and graphs do not reflect any deduction of taxes that a
   shareholder would pay on distributions or Fund-share redemptions. Total
   returns reflect maximum applicable sales charges explained in this paragraph,

   distributions. The graphs assume an initial investment of $25,000 for Class A
   shares and $10,000 for all other classes and reflect the deduction of all
   sales charges that would have applied for the period of investment. Class A
   shares generally have a $25,000 minimum initial investment with no minimum

   of $100,000 or more invested in any share classes of any of the MainStay
   Funds, the minimum initial investment is $15,000. Investor Class shares and
   Class A shares are sold with a maximum initial sales charge of 5.50%, no
   contingent deferred sales charge ("CDSC") and an annual 12b-1 fee of 0.25%.
   Class I shares are sold with no initial sales charge or CDSC, have no annual
   12b-1 fee, and are generally available to corporate and institutional
   investors or individual investors with a minimum initial investment of $5
   million or more. Class R2 shares are sold with no initial sales charge or
   CDSC, and have an annual 12b-1 fee of 0.25%. Class R2 shares are available
   only through corporate-sponsored retirement programs, which include certain
   minimum program requirements. Class R3 shares are sold with no initial sales
   charge or CDSC, have an annual 12b-1 fee of 0.50%, and are available in

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY RETIREMENT 2020 FUND
(UNAUDITED)
- --------------------------------------------------------------------------------

The example below is intended to describe the fees and expenses borne by
shareholders during the six-month period from November 1, 2009, to April 30,
2010, and the impact of those costs on your investment.

EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, exchange fees, and sales charges (loads) on
purchases (as applicable), and (2) ongoing costs, including management fees,
distribution and/or service (12b-1) fees, and other Fund expenses (as
applicable). This example is intended to help you understand your ongoing costs
(in dollars) of investing in the Fund and to compare these costs with the
ongoing costs of investing in other mutual funds. The example is based on an
investment of $1,000 made at the beginning of the six-month period and held for
the entire period from November 1, 2009, to April 30, 2010.

This example illustrates your Fund's ongoing costs in two ways:

- - ACTUAL EXPENSES
The second and third data columns in the table below provide information about
actual account values and actual expenses. You may use the information in these
columns, together with the amount you invested, to estimate the expenses that
you paid during the six-months ended April 30, 2010. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number under the heading entitled "Expenses Paid
During Period" to estimate the expenses you paid on your account during this
period.

- - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The fourth and fifth data columns in the table below provide information about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense ratio and an assumed rate of return of 5% per year before expenses,
which is not the Fund's actual return. The hypothetical account values and
expenses may not be used to estimate the actual ending account balances or
expenses you paid for the six-month period shown. You may use this information
to compare the ongoing costs of investing in the Fund with the ongoing costs of
investing in other Funds. To do so, compare this 5% hypothetical example with
the 5% hypothetical examples that appear in the shareholder reports of the other
Funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as
redemption fees, if applicable, exchange fees, or sales charges (loads).
Therefore, the fourth and fifth data columns of the table are useful in
comparing ongoing costs only and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.

1. Expenses are equal to the Fund's annualized expense ratio of each class
   (0.47% for Investor Class, 0.37% for Class A, 0.12% for Class I, 0.47% for
   Class R2 and 0.72% for Class R3) multiplied by the average account value over
   the period, divided by 365 and multiplied by 181 (to reflect the one-half
   year period). The table above represents the actual expenses incurred during
   the one-half year period. In addition to the fees and expenses which the Fund
   bears directly, the Fund indirectly bears a pro rata share of the fees and
   expenses of the Underlying Portfolio/Funds in which it invests. Such indirect
   expenses are not included in the above-reported expense figures.

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

QUESTIONS ANSWERED BY PORTFOLIO MANAGERS TONY ELAVIA AND JONATHAN SWANEY OF
MADISON SQUARE INVESTORS LLC, THE FUND'S SUBADVISOR.

HOW DID MAINSTAY RETIREMENT 2020 FUND PERFORM RELATIVE TO ITS PEERS AND ITS
BENCHMARK DURING THE SIX MONTHS ENDED APRIL 30, 2010?

Excluding all sales charges, MainStay Retirement 2020 Fund returned 9.41% for
Investor Class shares and 9.49% for Class A shares for the six months ended
April 30, 2010. Over the same period, the Fund's Class I shares returned 9.53%,
Class R2 shares returned 9.36% and Class R3 shares returned 9.21%. All share
classes underperformed the 9.79% return of the average Lipper(1) mixed-asset
target 2020 fund and the 15.66% return of the S&P 500(R) Index(2) for the six
months ended April 30, 2010. As of April 30, 2010, Class R1 shares had not
commenced investment operations. The S&P 500(R) Index is the Fund's broad-based
securities-market index. See page 20 for Fund returns with sales charges.

WHAT FACTORS CONTRIBUTED TO THE FUND'S RELATIVE PERFORMANCE DURING THE REPORTING
PERIOD?

The Fund invests in other mutual funds referred to as Underlying Funds. The
Underlying Funds may invest in fixed-income securities or in domestic or
international stocks at various capitalization levels. The Fund's primary
benchmark, on the other hand, consists entirely of U.S. large-cap stocks. These
asset-class differences accounted for much of the Fund's underperformance of the
S&P 500(R) Index. Even with the Fund's asset-allocation targets taken into
account, however, performance was moderately below our expectations.
Disappointing results from several Underlying Funds, particularly those that use
quantitative stock selection, detracted from the Fund's performance relative to
the S&P 500(R) Index and the Fund's average Lipper peer fund. The Fund also had
negative beta exposure (or lower volatility than the market as a whole) in a
period when the stock market was rising. In addition, the Fund suffered from a
slight bias toward growth-oriented stocks in a period when value stocks were in
favor.

DURING THE REPORTING PERIOD, HOW DID YOU DETERMINE THE FUND'S ALLOCATIONS AMONG
THE UNDERLYING FUNDS?

In managing the Fund, we considered a variety of information, including
portfolio-level characteristics of the Underlying Funds, such as capitalization,
style biases and sector exposures. We also examined the attributes of the
Underlying Funds' holdings, such as valuation metrics, earnings data and
technical indicators. Finally, we evaluated the historical success of the
portfolio managers responsible for the Underlying Funds.

In general, we sought Underlying Equity Funds that had a track record of capable
portfolio management, that occupied attractively valued market segments and that
invested in companies with fairly priced securities and strong price and
earnings momentum. During the reporting period, these techniques were generally
unsuccessful, as they steered the Fund into Underlying Funds that collectively
underperformed the S&P 500(R) Index after adjusting for Underlying Fund expenses
and the Fund's strategic allocation policy.

Underlying Fixed Income Funds were selected based upon the type and country of
issuance of the securities in which they invested, the average credit quality of
those securities and their duration.(3)

It is usually difficult to identify any single factor that had a
disproportionate effect on the Fund's relative performance, but during the
reporting period, one theme had a distinctive impact. We tilted the Fund toward
Underlying Funds that prized earnings stability, because higher-quality stocks
with stable earnings have historically been rewarded with higher returns than
lower-quality stocks with earnings that are less stable. Unfortunately, when the
global equity markets turned positive in the spring of 2009, investors
aggressively bought the riskiest and lowest-quality securities in anticipation
that these securities would benefit most from a recovery. This trend persisted
throughout the reporting period, and stocks with negative earnings and cash
flows were among the best performers. This so-called junk rally served as a
significant drag on the Fund's relative performance during the reporting period.

DID YOU MAKE ANY SIGNIFICANT CHANGES IN THE FUND'S ALLOCATIONS DURING THE
REPORTING PERIOD?

The most noteworthy change we made during the reporting period was a gradual,
protracted shift away from large-cap growth-oriented Underlying Funds toward
Underlying Funds with a more neutral style and capitalization focus.
Specifically, we reduced the Fund's allocations to MainStay Large Cap Growth
Fund, MainStay Growth Equity Fund and MainStay 130/30 Growth Fund and increased
the Fund's allocations to MainStay Epoch U.S. All Cap Fund and, to a lesser
degree, to MainStay 130/30 Core Fund. This shift had a positive impact on the
Fund's performance, as value-oriented small-capitalization stocks

24    MainStay Retirement 2020 Fund



outpaced growth-oriented larger-cap stocks as the reporting period progressed.
We have substantially reduced the Fund's exposure to growth-oriented stocks over
the past two and a half years. At the end of the current reporting period, the
Fund was evenly positioned between growth and value.

During the reporting period, the Fund initiated new positions in Columbia Small
Cap Index Fund, MainStay Epoch Global Choice Fund and MainStay Convertible Fund.
We selected Columbia Small Cap Index Fund to gain pure exposure to the small-cap
segment of the U.S. stock market. We chose MainStay Epoch Global Choice Fund to
further diversify the Fund across management strategies and to enhance the
Fund's exposure to desirable cash flow metrics. MainStay Convertible Fund was
chosen to increase the Fund's responsiveness to movements in the equity market
while incrementally lowering the Fund's average credit quality and duration.

DURING THE REPORTING PERIOD, WHICH UNDERLYING EQUITY FUND POSITIONS HAD THE
HIGHEST TOTAL RETURNS AND WHICH HAD THE LOWEST TOTAL RETURNS?

Columbia Small Cap Index Fund, MainStay U.S. Small Cap Fund and MainStay Epoch
U.S. All Cap Fund generated the best total returns among the Underlying Equity
Funds in which the Fund invested, as these Underlying Funds invested most
heavily in smaller-capitalization stocks. The worst returns came from Underlying
Equity Funds that invest abroad, namely MainStay ICAP International Fund,
MainStay 130/30 International Fund and MainStay International Equity Fund. These
Underlying Funds were hampered not only by comparatively weak overseas returns
in local currencies but also by a strengthening U.S. dollar.

DURING THE REPORTING PERIOD, WHICH UNDERLYING EQUITY FUNDS MADE THE STRONGEST
CONTRIBUTIONS TO THE FUND'S ABSOLUTE PERFORMANCE AND WHICH UNDERLYING EQUITY
FUNDS DETRACTED THE MOST?

On an absolute basis, the strongest contributions to the Fund's equity
performance came from the Fund's largest Underlying Equity Fund holdings, namely
MainStay MAP Fund and MainStay Growth Equity Fund.

During the reporting period, no Underlying Equity Funds in which the Fund
invested provided negative
returns. The weakest contributions to the Fund's performance came from two of
its smallest positions, MainStay S&P 500 Index Fund and MainStay Epoch Global
Choice Fund.

WHAT FACTORS INFLUENCED PERFORMANCE IN THE FIXED-INCOME PORTION OF THE FUND?

U.S. Treasury yields were largely unchanged over the course of the reporting
period. Signs of economic strength, improving corporate profitability and a
large supply of new issuance threatened to push rates higher. These factors,
however, were offset by concerns about corporate and sovereign default risk
(holding company Dubai World and Greece were notable examples) and by questions
about the sustainability of the economic recovery. Lower-quality fixed-income
securities generally outperformed higher-quality fixed-income securities as
credit spreads(4) narrowed, driving bond prices higher.

HOW DID THE FUND ALLOCATE ASSETS AMONG THE UNDERLYING FIXED INCOME FUNDS DURING
THE REPORTING PERIOD?

In anticipation that Treasury rates would ultimately rise and that credit
spreads would continue to narrow from the wider-than-normal levels we had
observed, we shortened the Fund's duration and reestablished a bias toward
lower-quality instruments. We implemented these strategies primarily by
increasing the Fund's holdings in MainStay Floating Rate Fund, MainStay High
Yield Opportunities Fund and MainStay High Yield Corporate Bond Fund.

DURING THE REPORTING PERIOD, WHICH UNDERLYING FIXED INCOME FUNDS HAD THE
STRONGEST ABSOLUTE PERFORMANCE AND WHICH ONES DETRACTED FROM THE FUND'S ABSOLUTE
PERFORMANCE?

The Fund's best-performing Underlying Fixed Income Fund holdings were MainStay
High Yield Opportunities Fund and MainStay High Yield Corporate Bond Fund, both
of which benefited from the contraction in credit spreads that accompanied the
economic recovery. The worst-performing Underlying Fixed Income Fund--and the
only Fund holding that provided a negative return--was American Century
International Bond Fund. This Underlying Fund was hurt by the potential for
sovereign defaults and by a rising U.S. dollar.

1. Performance tables and graphs do not reflect any deduction of taxes that a
   shareholder would pay on distributions or Fund-share redemptions. Total
   returns reflect maximum applicable sales charges explained in this paragraph,
   change in share price, and reinvestment of dividend and capital gain
   distributions. The graphs assume an initial investment of $25,000 for Class A
   shares and $10,000 for all other classes and reflect the deduction of all
   sales charges that would have applied for the period of investment. Class A
   shares generally have a $25,000 minimum initial investment with no minimum
   subsequent purchase amount. For investors that, in the aggregate, have assets
   of $100,000 or more invested in any share classes of any of the MainStay
   Funds, the minimum initial investment is $15,000. Investor Class shares and
   Class A shares are sold with a maximum initial sales charge of 5.50%, no
   contingent deferred sales charge ("CDSC") and an annual 12b-1 fee of 0.25%.
   Class I shares are sold with no initial sales charge or CDSC, have no annual
   12b-1 fee, and are generally available to corporate and institutional
   investors or individual investors with a minimum initial investment of $5
   million or more. Class R2 shares are sold with no initial sales charge or
   CDSC, and have an annual 12b-1 fee of 0.25%. Class R2 shares are available
   only through corporate-sponsored retirement programs, which include certain
   minimum program requirements. Class R3 shares are sold with no initial sales
   charge or CDSC, have an annual 12b-1 fee of 0.50%, and are available in
   certain individual retirement accounts or in certain retirement plans.
   Performance figures reflect certain fee waivers and/or expense limitations,
   without which total returns may have been lower. For information on

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY RETIREMENT 2030 FUND
(UNAUDITED)
- --------------------------------------------------------------------------------

The example below is intended to describe the fees and expenses borne by
shareholders during the six-month period from November 1, 2009, to April 30,
2010, and the impact of those costs on your investment.

EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, exchange fees, and sales charges (loads) on
purchases (as applicable), and (2) ongoing costs, including management fees,
distribution and/or service (12b-1) fees, and other Fund expenses (as
applicable). This example is intended to help you understand your ongoing costs
(in dollars) of investing in the Fund and to compare these costs with the
ongoing costs of investing in other mutual funds. The example is based on an
investment of $1,000 made at the beginning of the six-month period and held for
the entire period from November 1, 2009, to April 30, 2010.

This example illustrates your Fund's ongoing costs in two ways:

- - ACTUAL EXPENSES
The second and third data columns in the table below provide information about
actual account values and actual expenses. You may use the information in these
columns, together with the amount you invested, to estimate the expenses that
you paid during the six-months ended April 30, 2010. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number under the heading entitled "Expenses Paid
During Period" to estimate the expenses you paid on your account during this
period.

- - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The fourth and fifth data columns in the table below provide information about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense ratio and an assumed rate of return of 5% per year before expenses,
which is not the Fund's actual return. The hypothetical account values and
expenses may not be used to estimate the actual ending account balances or
expenses you paid for the six-month period shown. You may use this information
to compare the ongoing costs of investing in the Fund with the ongoing costs of
investing in other Funds. To do so, compare this 5% hypothetical example with
the 5% hypothetical examples that appear in the shareholder reports of the other
Funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as
redemption fees, if applicable, exchange fees, or sales charges (loads).
Therefore, the fourth and fifth data columns of the table are useful in
comparing ongoing costs only and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.

   (0.47% for Investor Class, 0.37% for Class A, 0.12% for Class I, 0.47% for
   Class R2 and 0.72% for Class R3) multiplied by the average account value over
   the period, divided by 365 and multiplied by 181 (to reflect the one-half
   year period). The table above represents the actual expenses incurred during
   the one-half year period. In addition to the fees and expenses which the Fund
   bears directly, the Fund indirectly bears a pro rata share of the fees and
   expenses of the Underlying Funds in which it invests. Such indirect expenses
   are not included in the above-reported expense figures.

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

QUESTIONS ANSWERED BY PORTFOLIO MANAGERS TONY ELAVIA AND JONATHAN SWANEY OF
MADISON SQUARE INVESTORS LLC, THE FUND'S SUBADVISOR.

HOW DID MAINSTAY RETIREMENT 2030 FUND PERFORM RELATIVE TO ITS PEERS AND ITS
BENCHMARK DURING THE SIX MONTHS ENDED APRIL 30, 2010?

Excluding all sales charges, MainStay Retirement 2030 Fund returned 10.61% for
Investor Class shares and 10.70% for Class A shares for the six months ended
April 30, 2010. Over the same period, the Fund's Class I shares returned 10.96%,
Class R2 shares returned 10.70% and Class R3 shares returned 10.54%. All share
classes underperformed the 11.78% return of the average Lipper(1) mixed-asset
target 2030 fund and the 15.66% return of the S&P 500(R) Index() for the six
months ended April 30, 2010. As of April 30, 2010, Class R1 shares had not
commenced investment operations. The S&P 500(R) Index is the Fund's broad-based
securities-market index. See page 34 for Fund returns with sales charges.

WHAT FACTORS CONTRIBUTED TO THE FUND'S RELATIVE PERFORMANCE DURING THE REPORTING
PERIOD?

The Fund invests in other mutual funds referred to as Underlying Funds. The
Underlying Funds may invest in fixed-income securities or in domestic or
international stocks at various capitalization levels. The Fund's primary
benchmark, on the other hand, consists entirely of U.S. large-cap stocks. These
asset-class differences accounted for much of the Fund's underperformance of the
S&P 500(R) Index. Even with the Fund's asset-allocation targets taken into
account, however, performance was moderately below our expectations.
Disappointing results from several Underlying Funds, particularly those that use
quantitative stock selection, detracted from the Fund's performance relative to
the S&P 500(R) Index and the Fund's average Lipper peer fund. The Fund also had
negative beta exposure (or lower volatility than the market as a whole) in a
period when the stock market was rising. In addition, the Fund suffered from a
slight bias toward growth-oriented stocks in a period when value stocks were in
favor.

DURING THE REPORTING PERIOD, HOW DID YOU DETERMINE THE FUND'S ALLOCATIONS AMONG
THE UNDERLYING FUNDS?

In managing the Fund, we considered a variety of information, including
portfolio-level characteristics of the Underlying Funds, such as capitalization,
style biases and sector exposures. We also examined the attributes of the
Underlying Funds' holdings, such as valuation metrics, earnings data and
technical indicators. Finally, we evaluated the historical success of the
portfolio managers responsible for the Underlying Funds.

In general, we sought Underlying Equity Funds that had a track record of capable
portfolio management, that occupied attractively valued market segments and that
invested in companies with fairly priced securities and strong price and
earnings momentum. During the reporting period, these techniques were generally
unsuccessful, as they steered the Fund into Underlying Funds that collectively
underperformed the S&P 500(R) Index after adjusting for Underlying Fund expenses
and the Fund's strategic allocation policy.

Underlying Fixed Income Funds were selected based upon the type and country of
issuance of the securities in which they invested, the average credit quality of
those securities and their duration.(3)

It is usually difficult to identify any single factor that had a
disproportionate effect on the Fund's relative performance, but during the
reporting period, one theme had a distinctive impact. We tilted the Fund toward
Underlying Funds that prized earnings stability, because higher-quality stocks
with stable earnings have historically been rewarded with higher returns than
lower-quality stocks with earnings that are less stable. Unfortunately, when the
global equity markets turned positive in the spring of 2009, investors
aggressively bought the riskiest and lowest-quality securities in anticipation
that these securities would benefit most from a recovery. This trend persisted
throughout the reporting period, and stocks with negative earnings and cash
flows were among the best performers. This so-called junk rally served as a
significant drag on the Fund's relative performance during the reporting period.

DID YOU MAKE ANY SIGNIFICANT CHANGES IN THE FUND'S ALLOCATIONS DURING THE
REPORTING PERIOD?

The most noteworthy change we made during the reporting period was a gradual,
protracted shift away from large-cap growth-oriented Underlying Funds toward
Underlying Funds with a more neutral style and capitalization focus.
Specifically, we reduced the Fund's allocations to MainStay Large Cap Growth
Fund, MainStay Growth Equity Fund and MainStay 130/30 Growth Fund and increased
the Fund's allocations to MainStay Epoch U.S. All Cap Fund and, to a lesser
degree, to MainStay 130/30 Core Fund. This

38    MainStay Retirement 2030 Fund



shift had a positive impact on the Fund's performance, as value-oriented
smaller-capitalization stocks outpaced growth-oriented larger-cap stocks as the
reporting period progressed. We have substantially reduced the Fund's exposure
to growth-oriented stocks over the past two and a half years. At the end of the
current reporting period, the Fund was evenly positioned between growth and
value.

During the reporting period, the Fund initiated new positions in Columbia Small
Cap Index Fund, MainStay Epoch Global Choice Fund and MainStay Convertible Fund.
We selected Columbia Small Cap Index Fund to gain pure exposure to the small-cap
segment of the U.S. stock market. We chose MainStay Epoch Global Choice Fund to
further diversify the Fund across management strategies and to enhance the
Fund's exposure to desirable cash flow metrics. MainStay Convertible Fund was
chosen to increase the Fund's responsiveness to movements in the equity market
while incrementally lowering the Fund's average credit quality and duration.

DURING THE REPORTING PERIOD, WHICH UNDERLYING EQUITY FUND POSITIONS HAD THE
HIGHEST TOTAL RETURNS AND WHICH HAD THE LOWEST TOTAL RETURNS?

Columbia Small Cap Index Fund, MainStay U.S. Small Cap Fund and MainStay Epoch
U.S. All Cap Fund generated the best total returns among the Underlying Equity
Funds in which the Fund invested, as these Underlying Funds invested most
heavily in smaller-capitalization stocks. The worst returns came from Underlying
Equity Funds that invest abroad, namely MainStay ICAP International Fund,
MainStay 130/30 International Fund and MainStay International Equity Fund. These
Underlying Funds were hampered not only by comparatively weak overseas returns
in local currencies but also by a strengthening U.S. dollar.

DURING THE REPORTING PERIOD, WHICH UNDERLYING EQUITY FUNDS MADE THE STRONGEST
CONTRIBUTIONS TO THE FUND'S ABSOLUTE PERFORMANCE AND WHICH UNDERLYING EQUITY
FUNDS DETRACTED THE MOST?

On an absolute basis, the strongest contributions to the Fund's equity
performance came from the Fund's largest Underlying Equity Fund holdings, namely
MainStay MAP Fund and MainStay Growth Equity Fund.


During the reporting period, no Underlying Equity Funds in which the Fund
invested provided negative returns. The weakest contributions to the Fund's
performance came from two of its smallest positions, MainStay S&P 500 Index Fund
and MainStay Epoch Global Choice Fund.

WHAT FACTORS INFLUENCED PERFORMANCE IN THE FIXED-INCOME PORTION OF THE FUND?

U.S. Treasury yields were largely unchanged over the course of the reporting
period. Signs of economic strength, improving corporate profitability and a
large supply of new issuance threatened to push rates higher. These factors,
however, were offset by concerns about corporate and sovereign default risk
(holding company Dubai World and Greece were notable examples) and by questions
about the sustainability of the economic recovery. Lower-quality fixed-income
securities generally outperformed higher-quality fixed-income securities as
credit spreads(4) narrowed, driving bond prices higher.

HOW DID THE FUND ALLOCATE ASSETS AMONG THE UNDERLYING FIXED INCOME FUNDS DURING
THE REPORTING PERIOD?

In anticipation that Treasury rates would ultimately rise and that credit
spreads would continue to narrow from the wider-than-normal levels we had
observed, we shortened the Fund's duration and reestablished a bias toward
lower-quality instruments. We implemented these strategies primarily by
increasing the Fund's holdings in MainStay Floating Rate Fund, MainStay High
Yield Opportunities Fund and MainStay High Yield Corporate Bond Fund.

DURING THE REPORTING PERIOD, WHICH UNDERLYING FIXED INCOME FUNDS HAD THE
STRONGEST ABSOLUTE PERFORMANCE AND WHICH ONES DETRACTED FROM THE FUND'S ABSOLUTE
PERFORMANCE?

The Fund's best-performing Underlying Fixed Income Fund holdings were MainStay
High Yield Opportunities Fund and MainStay High Yield Corporate Bond Fund, both
of which benefited from the contraction

in credit spreads that accompanied the economic recovery. The worst-performing
Underlying Fixed Income Fund--and the only Fund holding that provided a negative
return--was American Century International Bond Fund. This Underlying Fund was
hurt by the potential for sovereign defaults and by a rising U.S. dollar.

1. Performance tables and graphs do not reflect any deduction of taxes that a
   shareholder would pay on distributions or Fund-share redemptions. Total
   returns reflect maximum applicable sales charges explained in this paragraph,
   change in share price, and reinvestment of dividend and capital gain
   distributions. The graphs assume an initial investment of $25,000 for Class A
   shares and $10,000 for all other classes and reflect the deduction of all
   sales charges that would have applied for the period of investment. Class A
   shares generally have a $25,000 minimum initial investment with no minimum
   subsequent purchase amount. For investors that, in the aggregate, have assets
   of $100,000 or more invested in any share classes of any of the MainStay
   Funds, the minimum initial investment is $15,000. Investor Class shares and
   Class A shares are sold with a maximum initial sales charge of 5.50%, no
   contingent deferred sales charge ("CDSC") and an annual 12b-1 fee of 0.25%.
   Class I shares are sold with no initial sales charge or CDSC, have no annual
   12b-1 fee, and are generally available to corporate and institutional
   investors or individual investors with a minimum initial investment of $5
   million or more. Class R2 shares are sold with no initial sales charge or
   CDSC, and have an annual 12b-1 fee of 0.25%. Class R2 shares are available
   only through corporate-sponsored retirement programs, which include certain
   minimum program requirements. Class R3 shares are sold with no initial sales
   charge or CDSC, have an annual 12b-1 fee of

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY RETIREMENT 2040 FUND
(UNAUDITED)
- --------------------------------------------------------------------------------

The example below is intended to describe the fees and expenses borne by
shareholders during the six-month period from November 1, 2009, to April 30,
2010, and the impact of those costs on your investment.

EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, exchange fees, and sales charges (loads) on
purchases (as applicable), and (2) ongoing costs, including management fees,
distribution and/or service (12b-1) fees, and other Fund expenses (as
applicable). This example is intended to help you understand your ongoing costs
(in dollars) of investing in the Fund and to compare these costs with the
ongoing costs of investing in other mutual funds. The example is based on an
investment of $1,000 made at the beginning of the six-month period and held for
the entire period from November 1, 2009, to April 30, 2010.

This example illustrates your Fund's ongoing costs in two ways:

- - ACTUAL EXPENSES
The second and third data columns in the table below provide information about
actual account values and actual expenses. You may use the information in these
columns, together with the amount you invested, to estimate the expenses that
you paid during the six-months ended April 30, 2010. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number under the heading entitled "Expenses Paid
During Period" to estimate the expenses you paid on your account during this
period.

- - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The fourth and fifth data columns in the table below provide information about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense ratio and an assumed rate of return of 5% per year before expenses,
which is not the Fund's actual return. The hypothetical account values and
expenses may not be used to estimate the actual ending account balances or
expenses you paid for the six-month period shown. You may use this information
to compare the ongoing costs of investing in the Fund with the ongoing costs of
investing in other Funds. To do so, compare this 5% hypothetical example with
the 5% hypothetical examples that appear in the shareholder reports of the other
Funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as
redemption fees, if applicable, exchange fees, or sales charges (loads).
Therefore, the fourth and fifth data columns of the table are useful in
comparing ongoing costs only and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.

1. Expenses are equal to the Fund's annualized expense ratio of each class
   (0.47% for Investor Class, 0.37% for Class A, 0.12% for Class I, 0.47% for
   Class R2 and 0.72% for Class R3) multiplied by the average account value over
   the period, divided by 365 and multiplied by 181 (to reflect the one-half
   year period). The table above represents the actual expenses incurred during
   the one-half year period. In addition to the fees and expenses which the Fund
   bears directly, the Fund indirectly bears a pro rata share of the fees and
   expenses of the Underlying Funds in which it invests. Such indirect expenses
   are not included in the above-reported expense figures.

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

QUESTIONS ANSWERED BY PORTFOLIO MANAGERS TONY ELAVIA AND JONATHAN SWANEY OF
MADISON SQUARE INVESTORS LLC, THE FUND'S SUBADVISOR.

HOW DID MAINSTAY RETIREMENT 2040 FUND PERFORM RELATIVE TO ITS PEERS AND ITS
BENCHMARK DURING THE SIX MONTHS ENDED APRIL 30, 2010?

Excluding all sales charges, MainStay Retirement 2040 Fund returned 11.37% for
Investor Class shares and 11.48% for Class A shares for the six months ended
April 30, 2010. Over the same period, the Fund's Class I shares returned 11.59%,
Class R2 shares returned 11.45% and Class R3 shares returned 11.21%. All share
classes underperformed the 12.72% return of the average Lipper(1) mixed-asset
target 2040 fund and the 15.66% return of the S&P 500(R) Index(2) for the six
months ended April 30, 2010. As of April 30, 2010, Class R1 shares had not
commenced investment operations. The S&P 500(R) Index is the Fund's broad-based
securities-market index. See page 48 for Fund returns with sales charges.

WHAT FACTORS CONTRIBUTED TO THE FUND'S RELATIVE PERFORMANCE DURING THE REPORTING
PERIOD?

The Fund invests in other mutual funds referred to as Underlying Funds. The
Underlying Funds may invest in fixed-income securities or in domestic or
international stocks at various capitalization levels. The Fund's primary
benchmark, on the other hand, consists entirely of U.S. large-cap stocks. These
asset-class differences accounted for much of the Fund's underperformance of the
S&P 500(R) Index. Even with the Fund's asset-allocation targets taken into
account, however, performance was significantly below our expectations.
Disappointing results from several Underlying Funds, particularly those that use
quantitative stock selection, detracted from the Fund's performance relative to
the S&P 500(R) Index and the Fund's average Lipper peer fund. The Fund also had
negative beta exposure (or lower volatility than the market as a whole) in a
period when the stock market was rising. In addition, the Fund suffered from a
slight bias toward growth-oriented stocks in a period when value stocks were in
favor.

DURING THE REPORTING PERIOD, HOW DID YOU DETERMINE THE FUND'S ALLOCATIONS AMONG
THE UNDERLYING FUNDS?

In managing the Fund, we considered a variety of information, including
portfolio-level characteristics of the Underlying Funds, such as capitalization,
style biases and sector exposures. We also examined the attributes of the
Underlying Funds' holdings, such as valuation metrics, earnings data and
technical indicators. Finally, we evaluated the historical success of the
portfolio managers responsible for the Underlying Funds.

In general, we sought Underlying Equity Funds that had a track record of capable
portfolio management, that occupied attractively valued market segments and that
invested in companies with fairly priced securities and strong price and
earnings momentum. During the reporting period, these techniques were generally
unsuccessful, as they steered the Fund into Underlying Funds that collectively
underperformed the S&P 500(R) Index after adjusting for Underlying Fund expenses
and the Fund's strategic allocation policy.

Underlying Fixed Income Funds were selected based upon the type and country of
issuance of the securities in which they invested, the average credit quality of
those securities and their duration.(3)

It is usually difficult to identify any single factor that had a
disproportionate effect on the Fund's relative performance, but during the
reporting period, one theme had a distinctive impact. We tilted the Fund toward
Underlying Funds that prized earnings stability, because higher-quality stocks
with stable earnings have historically been rewarded with higher returns than
lower-quality stocks with earnings that are less stable. Unfortunately, when the
global equity markets turned positive in the spring of 2009, investors
aggressively bought the riskiest and lowest-quality securities in anticipation
that these securities would benefit most from a recovery. This trend persisted
throughout the reporting period, and stocks with negative earnings and cash
flows were among the best performers. This so-called junk rally served as a
significant drag on the Fund's relative performance during the reporting period.

DID YOU MAKE ANY SIGNIFICANT CHANGES IN THE FUND'S ALLOCATIONS DURING THE
REPORTING PERIOD?

The most noteworthy change we made during the reporting period was a gradual,
protracted shift away from large-cap growth-oriented Underlying Funds toward
Underlying Funds with a more neutral style and capitalization focus.
Specifically, we reduced the Fund's allocations to MainStay Large Cap Growth
Fund, MainStay Growth Equity Fund and MainStay 130/30 Growth Fund and increased
the Fund's allocations to MainStay Epoch U.S. All Cap Fund and, to a lesser
degree, to MainStay 130/30 Core Fund. This

   to changes in interest rates. Duration is expressed as a number of years and
   is considered a more accurate sensitivity gauge than average maturity.

52    MainStay Retirement 2040 Fund



shift had a positive impact on the Fund's performance, as value-oriented
smaller-capitalization stocks outpaced growth-oriented larger-cap stocks as the
reporting period progressed. We have substantially reduced the Fund's exposure
to growth-oriented stocks over the past two and a half years. At the end of the
current reporting period, the Fund was evenly positioned between growth and
value.

During the reporting period, the Fund initiated new positions in Columbia Small
Cap Index Fund, MainStay Epoch Global Choice Fund and MainStay Convertible Fund.
We selected Columbia Small Cap Index Fund to gain pure exposure to the small-cap
segment of the U.S. stock market. We chose MainStay Epoch Global Choice Fund to
further diversify the Fund across management strategies and to enhance the
Fund's exposure to desirable cash flow metrics. MainStay Convertible Fund was
chosen to increase the Fund's responsiveness to movements in the equity market
while incrementally lowering the Fund's average credit quality and duration.

DURING THE REPORTING PERIOD, WHICH UNDERLYING EQUITY FUND POSITIONS HAD THE
HIGHEST TOTAL RETURNS AND WHICH HAD THE LOWEST TOTAL RETURNS?

Columbia Small Cap Index Fund, MainStay U.S. Small Cap Fund and MainStay Epoch
U.S. All Cap Fund generated the best total returns among the Underlying Equity
Funds in which the Fund invested, as these Underlying Funds invested most
heavily in smaller-capitalization stocks. The worst returns came from Underlying
Equity Funds that invest abroad, namely MainStay ICAP International Fund,
MainStay 130/30 International Fund and MainStay International Equity Fund. These
Underlying Funds were hampered not only by comparatively weak overseas returns
in local currencies but also by a strengthening U.S. dollar.

DURING THE REPORTING PERIOD, WHICH UNDERLYING EQUITY FUNDS MADE THE STRONGEST
CONTRIBUTIONS TO THE FUND'S ABSOLUTE PERFORMANCE AND WHICH UNDERLYING EQUITY
FUNDS DETRACTED THE MOST?

On an absolute basis, the strongest contributions to the Fund's equity
performance came from the Fund's largest Underlying Equity Fund holdings, namely
MainStay MAP Fund and MainStay Growth Equity Fund.

During the reporting period, no Underlying Equity Funds in which the Fund
invested provided negative returns. The weakest contributions to the Fund's
performance came from two of its smallest positions, MainStay S&P 500 Index Fund
and MainStay Epoch Global Choice Fund.

WHAT FACTORS INFLUENCED PERFORMANCE IN THE FIXED-INCOME PORTION OF THE FUND?

U.S. Treasury yields were largely unchanged over the course of the reporting
period. Signs of economic strength, improving corporate profitability and a
large supply of new issuance threatened to push rates higher. These factors,
however, were offset by concerns about corporate and sovereign default risk
(holding company Dubai World and Greece were notable examples) and by questions
about the sustainability of the economic recovery. Lower-quality fixed-income
securities generally outperformed higher-quality fixed-income securities as
credit spreads(4) narrowed, driving bond prices higher.

HOW DID THE FUND ALLOCATE ASSETS AMONG THE UNDERLYING FIXED INCOME FUNDS DURING
THE REPORTING PERIOD?

In anticipation that Treasury rates would ultimately rise and that credit
spreads would continue to narrow from the wider-than-normal levels we had
observed, we shortened the Fund's duration and reestablished a bias toward
lower-quality instruments. We implemented these strategies primarily by
increasing the Fund's holdings in MainStay Floating Rate Fund, MainStay High
Yield Opportunities Fund and MainStay High Yield Corporate Bond Fund.

DURING THE REPORTING PERIOD, WHICH UNDERLYING FIXED INCOME FUNDS HAD THE
STRONGEST ABSOLUTE PERFORMANCE AND WHICH ONES DETRACTED FROM THE FUND'S ABSOLUTE
PERFORMANCE?

The Fund's best-performing Underlying Fixed Income Fund holdings were MainStay
High Yield Opportunities Fund and MainStay High Yield Corporate Bond Fund, both
of which benefited from the contraction in credit spreads that accompanied the
economic

recovery. The worst-performing Underlying Fixed Income Fund--and the only Fund
holding that provided a negative return--was American Century International Bond
Fund. This Underlying Fund was hurt by the potential for sovereign defaults and
by a rising U.S. dollar.

1. Performance tables and graphs do not reflect any deduction of taxes that a
   shareholder would pay on distributions or Fund-share redemptions. Total
   returns reflect maximum applicable sales charges explained in this paragraph,
   change in share price, and reinvestment of dividend and capital gain
   distributions. The graphs assume an initial investment of $25,000 for Class A
   shares and $10,000 for all other classes and reflect the deduction of all
   sales charges that would have applied for the period of investment. Class A
   shares generally have a $25,000 minimum initial investment with no minimum
   subsequent purchase amount. For investors that, in the aggregate, have assets
   of $100,000 or more invested in any share classes of any of the MainStay
   Funds, the minimum initial investment is $15,000. Investor Class shares and
   Class A shares are sold with a maximum initial sales charge of 5.50%, no
   contingent deferred sales charge ("CDSC") and an annual 12b-1 fee of 0.25%.
   Class I shares are sold with no initial sales charge or CDSC, have no annual
   12b-1 fee, and are generally available to corporate and institutional
   investors or individual investors with a minimum initial investment of $5
   million or more. Class R2 shares are sold with no initial sales charge or
   CDSC, and have an annual 12b-1 fee of 0.25%. Class R2 shares are available
   only through corporate-sponsored retirement programs, which include certain
   minimum program requirements. Class R3 shares are sold with no initial sales
   charge or CDSC, have an annual 12b-1 fee of 0.50%, and are available in
   certain individual retirement accounts or in certain retirement plans.
   Performance figures reflect certain fee waivers and/or expense limitations,
   without which total returns may have been lower. For information on current
   fee waivers and/or expense limitations, please refer to the notes to the
   financial statements.
2. Performance figures for Investor Class shares, first offered February 28,
   2008, include the historical performance of Class A shares through February
   27, 2008, adjusted for differences in expenses

The example below is intended to describe the fees and expenses borne by
shareholders during the six-month period from November 1, 2009, to April 30,
2010, and the impact of those costs on your investment.

EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, exchange fees, and sales charges (loads) on
purchases (as applicable), and (2) ongoing costs, including management fees,
distribution and/or service (12b-1) fees, and other Fund expenses (as
applicable). This example is intended to help you understand your ongoing costs
(in dollars) of investing in the Fund and to compare these costs with the
ongoing costs of investing in other mutual funds. The example is based on an
investment of $1,000 made at the beginning of the six-month period and held for
the entire period from November 1, 2009, to April 30, 2010.

This example illustrates your Fund's ongoing costs in two ways:

- - ACTUAL EXPENSES
The second and third data columns in the table below provide information about
actual account values and actual expenses. You may use the information in these
columns, together with the amount you invested, to estimate the expenses that
you paid during the six-months ended April 30, 2010. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number under the heading entitled "Expenses Paid
During Period" to estimate the expenses you paid on your account during this
period.

- - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The fourth and fifth data columns in the table below provide information about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense ratio and an assumed rate of return of 5% per year before expenses,
which is not the Fund's actual return. The hypothetical account values and
expenses may not be used to estimate the actual ending account balances or
expenses you paid for the six-month period shown. You may use this information
to compare the ongoing costs of investing in the Fund with the ongoing costs of
investing in other Funds. To do so, compare this 5% hypothetical example with
the 5% hypothetical examples that appear in the shareholder reports of the other
Funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as
redemption fees, if applicable, exchange fees, or sales charges (loads).
Therefore, the fourth and fifth data columns of the table are useful in
comparing ongoing costs only and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.

1. Expenses are equal to the Fund's annualized expense ratio of each class
   (0.47% for Investor Class, 0.37% for Class A, 0.12% for Class I, 0.47% for
   Class R2 and 0.72% for Class R3) multiplied by the average account value over
   the period, divided by 365 and multiplied by 181 (to reflect the one-half
   year period). The table above represents the actual expenses incurred during
   the one-half year period. In addition to the fees and expenses which the Fund
   bears directly, the Fund indirectly bears a pro rata share of the fees and
   expenses of the Underlying Funds in which it invests. Such indirect expenses
   are not included in the above-reported expense figures.

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

QUESTIONS ANSWERED BY PORTFOLIO MANAGERS TONY ELAVIA AND JONATHAN SWANEY OF
MADISON SQUARE INVESTORS LLC, THE FUND'S SUBADVISOR.

HOW DID MAINSTAY RETIREMENT 2050 FUND PERFORM RELATIVE TO ITS PEERS AND ITS
BENCHMARK DURING THE SIX MONTHS ENDED APRIL 30, 2010?

Excluding all sales charges, MainStay Retirement 2050 Fund returned 11.72% for
Investor Class shares and 11.93% for Class A shares for the six months ended
April 30, 2010. Over the same period, the Fund's Class I shares returned 12.06%,
Class R2 shares returned 11.87% and Class R3 shares returned 11.68%. All share
classes underperformed the 13.05% return of the average Lipper(1) mixed-asset
target 2050+ fund and the 15.66% return of the S&P 500(R) Index(2) for the six
months ended April 30, 2010. As of April 30, 2010, Class R1 shares had not
commenced investment operations. The S&P 500(R) Index is the Fund's broad-based
securities-market index. See page 62 for Fund returns with sales charges.

WHAT FACTORS CONTRIBUTED TO THE FUND'S RELATIVE PERFORMANCE DURING THE REPORTING
PERIOD?

The Fund invests in other mutual funds referred to as Underlying Funds. The
Underlying Funds may invest in fixed-income securities or in domestic or
international stocks at various capitalization levels. The Fund's primary
benchmark, on the other hand, consists entirely of U.S. large-cap stocks. These
asset-class differences accounted for much of the Fund's underperformance of the
S&P 500(R) Index. Even with the Fund's asset-allocation targets taken into
account, however, performance was significantly below our expectations.
Disappointing results from several Underlying Funds, particularly those that use
quantitative stock selection, detracted from the Fund's performance relative to
the S&P 500(R) Index and the Fund's average Lipper peer fund. The Fund also had
negative beta exposure (or lower volatility than the market as a whole) in a
period when the stock market was rising. In addition, the Fund suffered from a
slight bias toward growth-oriented stocks in a when value stocks were in favor.

DURING THE REPORTING PERIOD, HOW DID YOU DETERMINE THE FUND'S ALLOCATIONS AMONG
THE UNDERLYING FUNDS?

In managing the Fund, we considered a variety of information, including
portfolio-level characteristics of the Underlying Funds, such as capitalization,
style biases and sector exposures. We also examined the attributes of the
Underlying Funds' holdings, such as valuation metrics, earnings data and
technical indicators. Finally, we evaluated the historical success of the
portfolio managers responsible for the Underlying Funds.

In general, we sought Underlying Equity Funds that had a track record of capable
portfolio management, that occupied attractively valued market segments and that
invested in companies with fairly priced securities and strong price and
earnings momentum. During the reporting period, these techniques were generally
unsuccessful, as they steered the Fund into Underlying Funds that collectively
underperformed the S&P 500(R) Index after adjusting for Underlying Fund expenses
and the Fund's strategic allocation policy.

Underlying Fixed Income Funds were selected based upon the type and country of
issuance of the securities in which they invested, the average credit quality of
those securities and their duration.(3)

It is usually difficult to identify any single factor that had a
disproportionate effect on the Fund's relative performance, but during the
reporting period, one theme had a distinctive impact. We tilted the Fund toward
Underlying Funds that prized earnings stability, because higher-quality stocks
with stable earnings have historically been rewarded with higher returns than
lower-quality stocks with earnings that are less stable. Unfortunately, when the
global equity markets turned positive in the spring of 2009, investors
aggressively bought the riskiest and lowest-quality securities in anticipation
that these securities would benefit most from a recovery. This trend persisted
throughout the reporting period, and stocks with negative earnings and cash
flows were among the best performers. This so-called junk rally served as a
significant drag on the Fund's relative performance during the reporting period.

DID YOU MAKE ANY SIGNIFICANT CHANGES IN THE FUND'S ALLOCATIONS DURING THE
REPORTING PERIOD?

The most noteworthy change we made during the reporting period was a gradual,
protracted shift away from large-cap growth-oriented Underlying Funds toward
Underlying Funds with a more neutral style and capitalization focus.
Specifically, we reduced the Fund's allocations to MainStay Large Cap Growth
Fund, MainStay Growth Equity Fund and MainStay 130/30 Growth Fund and increased
the Fund's allocations to MainStay Epoch U.S. All Cap Fund and, to a lesser
degree, to MainStay 130/30 Core Fund. This shift had a positive impact on the
Fund's performance, as value-oriented smaller-capitalization stocks outpaced
growth-oriented larger-cap stocks as the reporting

2. See footnote on page 63 for more information on the S&P 500(R) Index.
3 Duration is a measure of the price sensitivity of a fixed-income investment to
  changes in interest rates. Duration is expressed as a number of years and is
  considered a more accurate sensitivity gauge than average maturity.

period progressed. We have substantially reduced the Fund's exposure to growth-
oriented stocks over the past two and a half years. At the end of the current
reporting period, the Fund was evenly positioned between growth and value.

During the reporting period, the Fund initiated new positions in Columbia Small
Cap Index Fund, MainStay Epoch Global Choice Fund and MainStay Convertible Fund.
We selected Columbia Small Cap Index Fund to gain pure exposure to the small-cap
segment of the U.S. stock market. We chose MainStay Epoch Global Choice Fund to
further diversify the Fund across management strategies and to enhance the
Fund's exposure to desirable cash flow metrics. MainStay Convertible Fund was
chosen to increase the Fund's responsiveness to movements in the equity market
while incrementally lowering the Fund's average credit quality and duration.

DURING THE REPORTING PERIOD, WHICH UNDERLYING EQUITY FUND POSITIONS HAD THE
HIGHEST TOTAL RETURNS AND WHICH HAD THE LOWEST TOTAL RETURNS?

Columbia Small Cap Index Fund, MainStay U.S. Small Cap Fund and MainStay Epoch
U.S. All Cap Fund generated the best total returns among the Underlying Equity
Funds in which the Fund invested, as these Underlying Funds invested most
heavily in smaller-capitalization stocks. The worst returns came from Underlying
Equity Funds that invest abroad, namely MainStay ICAP International Fund,
MainStay 130/30 International Fund and MainStay International Equity Fund. These
Underlying Funds were hampered not only by comparatively weak overseas returns
in local currencies but also by a strengthening U.S. dollar.

DURING THE REPORTING PERIOD, WHICH UNDERLYING EQUITY FUNDS MADE THE STRONGEST
CONTRIBUTIONS TO THE FUND'S ABSOLUTE PERFORMANCE AND WHICH UNDERLYING EQUITY
FUNDS DETRACTED THE MOST?

On an absolute basis, the strongest contributions to the Fund's equity
performance came from the Fund's largest Underlying Equity Fund holdings, namely
MainStay MAP Fund and MainStay Growth Equity Fund.

During the reporting period, no Underlying Equity Funds in which the Fund
invested provided negative returns. The weakest contributions to the Fund's
performance came from two of its smallest positions, MainStay S&P 500 Index Fund
and MainStay Epoch Global Choice Fund.

WHAT FACTORS INFLUENCED PERFORMANCE IN THE FIXED-INCOME PORTION OF THE FUND?

U.S. Treasury yields were largely unchanged over the course of the reporting
period. Signs of economic strength, improving corporate profitability and a
large supply of new issuance threatened to push rates higher. These factors,
however, were offset by concerns about corporate and sovereign default risk
(holding company Dubai World and Greece were notable examples) and by questions
about the sustainability of the economic recovery. Lower-quality fixed-income
securities generally outperformed higher-quality fixed-income securities as
credit spreads(4) narrowed, driving bond prices higher.

HOW DID THE FUND ALLOCATE ASSETS AMONG THE UNDERLYING FIXED INCOME FUNDS DURING
THE REPORTING PERIOD?

In anticipation that Treasury rates would ultimately rise and that credit
spreads would continue to narrow from the wider-than-normal levels we had
observed, we shortened the Fund's duration and reestablished a bias toward
lower-quality instruments. We implemented these strategies primarily by
increasing the Fund's holdings in MainStay Floating Rate Fund, MainStay High
Yield Opportunities Fund and MainStay High Yield Corporate Bond Fund.

DURING THE REPORTING PERIOD, WHICH UNDERLYING FIXED INCOME FUNDS HAD THE
STRONGEST ABSOLUTE PERFORMANCE AND WHICH ONES DETRACTED FROM THE FUND'S ABSOLUTE
PERFORMANCE?

The Fund's best-performing Underlying Fixed Income Fund holdings were MainStay
High Yield Opportunities Fund and MainStay High Yield Corporate Bond Fund, both
of which benefited from the contraction in credit spreads that accompanied the
economic recovery. The worst-performing Underlying Fixed Income Fund--and the
only Fund holding that provided a negative return--was American Century
International Bond Fund. This Underlying Fund was hurt by the potential for
sovereign defaults and by a rising U.S. dollar.

NOTE 1--ORGANIZATION AND BUSINESS:

MainStay Funds Trust (the "Trust") is organized as a Delaware Statutory Trust
and is governed by a Declaration of Trust dated April 8, 2009. The Trust is
registered under the Investment Company Act of 1940, as amended (the "1940 Act")
as an open-end management investment company, and is comprised of twenty-nine
funds (collectively referred to as the "Funds" and each individually, referred
to as a "Fund"). These financial statements and notes relate to the MainStay
Retirement 2010 Fund, MainStay Retirement 2020 Fund, MainStay Retirement 2030
Fund, MainStay Retirement 2040 Fund and MainStay Retirement 2050 Fund
(collectively referred to as the "Retirement Funds" and each individually
referred to as a "Retirement Fund"). Each is a diversified fund. Each Retirement
Fund is the successor of a series of Eclipse Funds Inc. with the same name (each
a "Predecessor Fund"). The reorganizations of the Predecessor Funds with and
into the respective Retirement Funds, which were not subject to shareholder
approval under applicable law, occurred on February 26, 2010. All information
regarding and references to periods prior to the commencement of operations of
each Retirement Fund relate to the respective Predecessor Fund.

The Retirement Funds each currently offer six classes of shares. Class A shares,
Class I shares, Class R1 shares, Class R2 shares, and Class R3 shares commenced
operations on June 29, 2007. Investor Class shares commenced operations on
February 28, 2008. Investor Class and Class A shares are offered at net asset
value ("NAV") per share plus an initial sales charge. No sales charge applies on
investments of $1 million or more (and certain other qualified purchases) in
Investor Class and Class A shares, but a contingent deferred sales charge is
imposed on certain redemptions of such shares within one year of the date of
purchase. Class I, Class R1, Class R2 and Class R3 shares are offered at NAV and
are not subject to a sales charge. Depending on eligibility, Investor Class
shares may convert to Class A shares and Class A shares may convert to Investor
Class shares. The six classes of shares have the same voting (except for issues
that relate solely to one class), dividend, liquidation and other rights, and
the same terms and conditions, except that Class R3 shares are subject to higher
distribution and/or service fee rates than the Investor Class, Class A and Class
R2 shares under a distribution plan pursuant to Rule 12b-1 under the 1940 Act.
Class I and Class R1 shares are not subject to a distribution or service fee.
Class R1, Class R2 and Class R3 shares are authorized to pay to New York Life
Investment Management LLC, its affiliates, or third-party service providers, as
compensation for services rendered to shareholders of Class R1, Class R2 or
Class R3 shares, a shareholder service fee. There were no shares outstanding as
of April 30, 2010 for Class R1 shares. Class R3 received additional investments
on April 30, 2008, and began investment activity on May 1, 2008. Class R2
received additional investments on January 7, 2009, and began investment
activity on January 8, 2009.

The investment objective for each of the Retirement Funds is as follows:

Each Retirement Fund seeks to maximize total return over time consistent with
its current investment allocation. Total return is defined as a combination of
long-term growth of capital and current income.

The RETIREMENT 2010 FUND is managed for the typical investor who has retired or
is seeking to retire before the year 2015 and who plans to withdraw the value of
the investor's account in the Fund gradually after retirement.

The RETIREMENT 2020 FUND is managed for the typical investor seeking to retire
between the years 2016 and 2025 and who plans to withdraw the value of the
investor's account in the Fund gradually after retirement.

The RETIREMENT 2030 FUND is managed for the typical investor seeking to retire
between the years 2026 and 2035 and who plans to withdraw the value of the
investor's account in the Fund gradually after retirement.

The RETIREMENT 2040 FUND is managed for the typical investor seeking to retire
between the years 2036 and 2045 and who plans to withdraw the value of the
investor's account in the Fund gradually after retirement.

The RETIREMENT 2050 FUND is managed for the typical investor seeking to retire
between the years 2046 and 2055 and who plans to withdraw the value of the
investor's account in the Fund gradually after retirement.

The Retirement Funds are funds-of-funds and may invest in other Funds of the
Trust as well as funds of the Eclipse Funds and The MainStay Funds, each a
Massachusetts business trust, and Eclipse Funds Inc., a Maryland Corporation,
for which New York Life Investment Management LLC also serves as manager
("Affiliated Underlying Funds"). The Retirement Funds may also invest in other
unaffiliated funds. ("Unaffiliated Underlying Funds" and, collectively with the
Affiliated Underlying Funds, the "Underlying Funds").

NOTE 2--SIGNIFICANT ACCOUNTING POLICIES:

The Retirement Funds prepare their financial statements in accordance with
accounting principles generally accepted in the United States of America
("GAAP") and follow the significant accounting policies described below.

(A) SECURITIES VALUATION.  Investments in Underlying Funds are valued at their
NAV at the close of business each day. The Retirement Funds' other investments
and securities held by the Affiliated Underlying Funds are valued as described
below.

Debt securities are valued at prices supplied by a pricing agent or broker
selected by the funds' manager in consultation with the funds' subadvisor, if
any, whose prices reflect

76    MainStay Retirement Funds



broker/dealer supplied valuations and electronic data processing techniques, if
such prices are deemed by the funds' manager in consultation with the funds'
subadvisor, if any, to be representative of market values, at the regular close
of trading of the New York Stock Exchange ("Exchange") (generally 4:00 p.m.
Eastern time) on each day the Exchange is open for business ("valuation date").

Equity securities are valued at the latest quoted sales prices as of the close
of regular trading on the Exchange on each valuation date. Securities that are
not traded on the valuation date are valued at the mean of the latest quoted bid
and asked prices. Prices normally are taken from the principal market in which
each security trades.

Temporary cash investments acquired over 60 days prior to maturity are valued
using the latest bid prices or using valuations based on a matrix system (which
considers such factors as security prices, yields, maturities, and ratings),
both as furnished by independent pricing services. Other temporary cash
investments which mature in 60 days or less ("short-term investments") are
valued at amortized cost. The amortized cost method involves valuing a security
at its cost on the date of purchase and thereafter assuming a constant
amortization to maturity of the difference between the principal amount due at
maturity and cost.

Securities for which market quotations are not readily available are valued by
methods deemed in good faith by the Funds' Board to represent fair value. Equity
and non-equity securities which may be valued in this manner include, but are
not limited to: (i) a security the trading for which has been halted or
suspended; (ii) a debt security that has recently gone into default and for
which there is not a current market quotation; (iii) a security of an issuer
that has entered into a restructuring; (iv) a security that has been de-listed
from a national exchange; (v) a security the market price of which is not
available from an independent pricing source or, if so provided, does not, in
the opinion of the fund's manager, reflect the security's market value; and (vi)
a security where the trading on that security's principal market is temporarily
closed at a time when, under normal conditions, it would be open. At April 30,
2010, the Retirement Funds did not hold securities that were valued in such a
manner.

"Fair value" is defined as the price that the Retirement Fund would receive upon
selling an investment in an orderly transaction to an independent buyer in the
principal or most advantageous market of the investment. Fair value measurements
are determined within a framework that has established a three-tier hierarchy
which maximizes the use of observable market data and minimizes the use of
unobservable inputs to establish classification of fair value measurements for
disclosure purposes. "Inputs" refer broadly to the assumptions that market
participants would use in pricing the asset or liability, including assumptions
about risk, such as the risk inherent in a particular valuation technique used
to measure fair value using a pricing model and/or the risk inherent in the
inputs for the valuation technique. Inputs may be observable or unobservable.
Observable inputs are inputs that reflect the assumptions market participants
would use in pricing the asset or liability based on market data obtained from
sources independent of the reporting entity. Unobservable inputs are inputs that
reflect the reporting entity's own assumptions about the assumptions market
participants would use in pricing the asset or liability developed based on the
information available in the circumstances. The inputs or methodology used for
valuing securities may not be an indication of the risks associated with
investing in those securities. The three-tier hierarchy of inputs is summarized
in the three broad Levels listed below.

- - Level 1--quoted prices in active markets for identical investments

- - Level 2--other significant observable inputs (including quoted prices for
  similar investments in active markets, interest rates and yield curves,
  prepayment speeds, credit risks, etc.)

- - Level 3--significant unobservable inputs (including the Retirement Fund's own
  assumptions about the assumptions that market participants would use in
  determining the fair value of investments)

The aggregate value by input level, as of April 30, 2010, for each Retirement
Fund's investments is included at the end of each Retirement Fund's Portfolio of
Investments.

The valuation techniques used by the Retirement Funds to measure fair value
during the six-month period ended April 30, 2010 maximized the use of observable
inputs and minimized the use of unobservable inputs. The Underlying Funds may
have utilized some of the following fair value techniques: multi-dimensional
relational pricing models, option adjusted spread pricing and estimating the
price that would have prevailed in a liquid market for an international equity
security given information available at the time of evaluation, when there are
significant events after the close of local foreign markets. For the six-month
period ended April 30, 2010, there have been no changes to the fair value
methodologies.

(B) FEDERAL INCOME TAXES.   Each of the Retirement Funds is treated as a
separate entity for federal income tax purposes. The Retirement Funds' policy is
to comply with the requirements of the Internal Revenue Code of 1986, as amended
(the "Internal Revenue Code") applicable to regulated investment companies and
to distribute all of the taxable income to the shareholders of each Retirement
Fund within the allowable time limits. Therefore, no federal income tax
provision is required.

Management evaluates its tax positions to determine if the tax positions taken
meet the minimum recognition threshold in connection with accounting for
uncertainties in income tax positions taken or expected to be taken for the

                                                   mainstayinvestments.com    77



NOTES TO FINANCIAL STATEMENTS UNAUDITED (CONTINUED)



purposes of measuring and recognizing tax liabilities in the financial
statements. Recognition of tax benefits of an uncertain tax position is required
only when the position is "more likely than not" to be sustained assuming
examination by taxing authorities. Management has analyzed the Retirement Funds'
tax positions taken on federal income tax returns for all open tax years
(current and prior three tax years), and has concluded that no provision for
federal income tax is required in the Retirement Funds' financial statements.
The Retirement Funds' federal and state income and federal excise tax returns
for tax years for which the applicable statutes of limitations have not expired
are subject to examination by the Internal Revenue Service and state departments
of revenue.

(C) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS.  Dividends and distributions
are recorded on the ex-dividend date. The Retirement Funds intend to declare and
pay dividends of net investment income and distributions of net realized capital
gains, if any, annually. Unless the shareholder elects otherwise, all dividends
and distributions are reinvested in the same class of shares of the respective
Retirement Fund, at NAV. Dividends and distributions to shareholders are
determined in accordance with federal income tax regulations and may differ from
GAAP.

(D) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  The Retirement Funds record
security transactions on the trade date. Realized gains and losses on security
transactions are determined using the identified cost method. Dividends and
distributions received by the Retirement Funds from the Underlying Funds are
recorded on the ex-dividend date.

Investment income and realized and unrealized gains and losses on investments of
the Retirement Funds are allocated to separate classes of shares pro rata based
upon their relative net assets on the date the income is earned or realized and
unrealized gains and losses are incurred.

(E) EXPENSES.  Expenses of the Trust are allocated to the individual Retirement
Funds in proportion to the net assets of the respective Retirement Funds when
the expenses are incurred, except where direct allocations of expenses can be
made. Expenses (other than transfer agent expenses and fees incurred under the
shareholder services plans and the distribution plans further discussed in Note
3(B)) are allocated to separate classes of shares pro rata based upon their
relative NAV on the date the expenses are incurred. The expenses borne by each
Retirement Fund, including those of related parties to the Retirement Funds, are
shown in the Statement of Operations.

In addition, the Retirement Funds bear a pro rata share of the fees and expenses
of the Underlying Funds in which they invest. Because the Underlying Funds have
varied expense and fee levels and the Retirement Funds may own different
proportions of the Underlying Funds at different times, the amount of fees and
expenses incurred indirectly by the Retirement Funds may vary.

(F) USE OF ESTIMATES.  In preparing financial statements in conformity with
GAAP, management makes estimates and assumptions that affect the reported
amounts and disclosures in the financial statements. Actual results could differ
from those estimates.

(G) INDEMNIFICATIONS.  Under the Trust's organizational documents, its officers
and trustees are indemnified against certain liabilities that may arise out of
performance of their duties to the Trust. Additionally, in the normal course of
business, the Retirement Funds enter into contracts with third-party service
providers that contain a variety of representations and warranties and which
provide general indemnifications. The Retirement Funds' maximum exposure under
these arrangements is unknown, as this would involve future claims that may be
made against the Retirement Funds that have not yet occurred. Based on
experience, management is of the view that the risk of loss in connection with
these potential indemnification obligations is remote. However, there can be no
assurance that material liabilities related to such obligations will not arise
in the future, which could adversely impact the Retirement Funds.

NOTE 3--FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER AND SUBADVISOR.  New York Life Investment Management LLC ("New York
Life Investments" or "Manager"), a registered investment adviser and an
indirect, wholly-owned subsidiary of New York Life Insurance Company ("New York
Life"), serves as the Retirement Funds' Manager, pursuant to an Amended and
Restated Management Agreement ("Management Agreement"). The Manager provides
offices, conducts clerical, recordkeeping and bookkeeping services, and keeps
most of the financial and accounting records required to be maintained by the
Retirement Funds. Except for the portion of salaries and expenses that are the
responsibility of the Fund, the Manager also pays the salaries and expenses of
all personnel affiliated with the Retirement Funds and the operational expenses
of the Retirement Funds. Madison Square Investors LLC ("Madison Square
Investors" or "Subadvisor"), a registered investment adviser and an indirect,
wholly-owned subsidiary of New York Life, serves as Subadvisor to the Retirement
Funds and is responsible for the day-to-day portfolio management of the
Retirement Funds. Pursuant to the terms of an Amended and Restated Subadvisory
Agreement between New York Life Investments and the Subadvisor, New York Life
Investments pays for the services of the Subadvisor.

Each Retirement Fund is contractually obligated to pay the Manager a monthly fee
for services performed and facilities furnished at an annual rate of 0.10% of
the average daily net assets of the respective Retirement Fund. New York Life

78    MainStay Retirement Funds



Investments has also contractually agreed to waive this fee so that the
effective management fee is 0.00%. This waiver may be modified or terminated
only with Board approval. Each Retirement Fund also indirectly pays a
proportionate share of the management fees paid to the investment advisers of
the Underlying Funds in which each Retirement Fund invests.

Effective August 1, 2009, New York Life Investments entered into written expense
limitation agreements under which it agreed to reimburse the expenses of the
appropriate Class of the Retirement Funds so that the total ordinary operating
expenses (total ordinary operating expenses excludes expense reimbursement from
transfer agent, taxes, interest, litigation, extraordinary expenses, brokerage
and other transaction expenses relating to the purchase or sale of portfolio
investments, and the fees and expenses of any other funds in which a Fund
invests) do not exceed the following percentages of average daily net assets:
Investor Class, 0.475%; Class A, 0.375%; Class I, 0.125%; Class R1, 0.225%;
Class R2, 0.475% and Class R3, 0.725%. The expense limitation agreement expires
on February 28, 2011 and is reviewed annually by the Board in connection with
its review of the Fund's investment advisory agreements. Based on its review,
the Board may agree to maintain, modify or terminate the agreement.

For the six-month period ended April 30, 2010, New York Life Investments earned
fees from the Retirement Funds as follows:

(E) SMALL AMOUNT FEE.  Shareholders with small accounts adversely impact the
cost of providing transfer agency services. In an effort to reduce total
transfer agency expenses, the Retirement Funds have implemented a small account
fee on certain types of accounts. Certain shareholders with an account balance
of less than $1,000 are charged an annual per account fee of $20 (assessed semi-
annually). These fees are included in transfer agent fees shown on the Statement
of Operations.

(F) CAPITAL.  At April 30, 2010, New York Life and its affiliates beneficially

are allocated among certain MainStay Retirement Funds based upon net assets and
other factors. Interest on any revolving credit loan is charged based upon the

NOTE 9--NEW ACCOUNTING PRONOUNCEMENT:

("ASU") No. 2010-06 "Improving Disclosures about Fair Value Measurements". ASU
2010-06 requires reporting entities to make new disclosures about amount and
reasons for significant transfers in and out of Level 1 and Level 2 fair value
measurements and input and valuation techniques used to measure fair value for
both recurring and nonrecurring fair value measurements that fall in either
Level 2 or Level 3, and information on purchased, sales, issuances, and
settlements in the roll forward of activity in Level 3 fair value measures. The
new and revised disclosure requirements are effective for interim and annual
reporting periods beginning after December 15, 2009 except for the disclosures
about purchased, sales, issuances, and settlements in the roll forward of
activity in Level 3 fair value measures, which are effective for fiscal years
beginning after December 15, 2010. As of April 30, 2010, the Retirement Funds
have adopted ASU 2010-06. The adoption of ASU 2010-06 has not impacted the
amounts reported in the Retirement Funds' financial statements; however, there
are additional disclosures in each of the Retirement Funds' Portfolio of
Investments.

NOTE 10--SUBSEQUENT EVENTS:

In connection with the preparation of the financial statements of the Retirement
Funds as of and for the fiscal six-month period ended April 30, 2010, events and
transactions subsequent to April 30, 2010 through the date the financial
statements were issued have been evaluated by the Retirement Funds' management
for possible adjustment and/or disclosure. No subsequent events requiring
financial statement adjustment or disclosure have been identified.

        MESSAGE FROM THE PRESIDENT AND SEMIANNUAL REPORT

        Unaudited - April 30, 2010



MESSAGE FROM THE PRESIDENT

During the six months ended April 30, 2010, stock and bond markets generally
advanced, despite some volatility in January and February. Domestic small-cap
stocks were particularly strong, and U.S. stocks at all capitalization levels
provided double digit returns. Value stocks outpaced growth stocks for companies
of all sizes during the reporting period.

International stocks provided positive returns overall, but results varied
widely by country. Concerns about Greece's ability to meet its debt obligations
led many investors to abandon their holdings in Greece and question their
investments in several peripheral European nations where perceived risk had
increased. For the six-month reporting period, equities in the Far East
(including Japan) tended to be stronger than those in Europe.

The economic recovery in the United States continued. Real gross domestic
product advanced in the first quarter of 2010, though at a slower pace than in
the fourth quarter of 2009. The Federal Open Market Committee kept the targeted
federal funds rate at a historically low level throughout the reporting period,
which prompted many investors to leave the safety of U.S. Treasury securities in
search of higher yield.

In the high-yield bond market, lower-rated credits tended to be the strongest
performers. With investment-grade investors crossing into high-yield territory,
however, the highest-rated high-yield credits also saw strong demand. In the
municipal market, new-issue supply was reduced by government incentives that
encouraged municipal issuers to raise funds in the taxable market. In the
leveraged-loan market, new issuance strengthened, but extensive repayments
caused the market as a whole to contract.


Throughout the six-month reporting period, MainStay's portfolio managers sought
to make the most of market conditions within the investment strategies and risk
parameters of their respective Funds. While individual markets and Fund results
may vary, our pursuit of competitive returns over full market cycles has never
changed.

The information that follows provides a closer look
at the securities, strategies and market conditions that affected your MainStay
Fund(s) during the six months ended April 30, 2010. Of course, past performance
is no guarantee of future results. Even in a rising market, we believe that
maintaining a long-term perspective can be valuable. At MainStay, we believe
that in all markets, broad diversification, gradual allocation adjustments and
regular portfolio reviews can help guide you toward your long-range financial
goals.

We thank you for choosing MainStay Funds, and we look forward to serving your
investment needs for many years to come.

Sincerely,

/s/ STEPHEN P. FISHER

Stephen P. Fisher
President

1. Performance tables and graphs do not reflect the deduction of taxes that a
   shareholder would pay on distributions or Fund-share redemptions. Total
   returns reflect maximum applicable sales charges explained in this paragraph,
   change in share price, and reinvestment of dividend and capital gain
   distributions. The graphs assume an initial investment of $25,000 for Class A
   shares and $10,000 for all other classes and reflect the deduction of all
   sales charges that would have applied for the period of investment. Class A
   shares generally have a $25,000 minimum initial investment with no minimum
   subsequent purchase amount. For investors that, in the aggregate, have assets
   of $100,000 or more invested in any share classes of any of the MainStay
   Funds, the minimum initial investment is $15,000. Investor Class shares and
   Class A shares are sold with a maximum initial sales charge of 3.00% and an
   annual 12b-1 fee of 0.25%. Class I shares are sold with no initial sales
   charge or contingent deferred sales charge, have no annual 12b-1 fee, and are
   generally available to corporate and institutional investors or individual
   investors with a minimum initial investment of $5 million. Performance
   figures reflect certain fee waivers and/or expense limitations, without which

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY S&P 500 INDEX FUND
(UNAUDITED)
- --------------------------------------------------------------------------------

The example below is intended to describe the fees and expenses borne by
shareholders during the six-month period from November 1, 2009, to April 30,
2010, and the impact of those costs on your investment.

EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, exchange fees, and sales charges (loads) on
purchases (as applicable), and (2) ongoing costs, including management fees,
distribution and/or service (12b-1) fees, and other Fund expenses (as
applicable). This example is intended to help you understand your ongoing costs
(in dollars) of investing in the Fund and to compare these costs with the
ongoing costs of investing in other mutual funds. The example is based on an
investment of $1,000 made at the beginning of the six-month period and held for
the entire period from November 1, 2009, to April 30, 2010.

This example illustrates your Fund's ongoing costs in two ways:

- - ACTUAL EXPENSES
The second and third data columns in the table below provide information about
actual account values and actual expenses. You may use the information in these
columns, together with the amount you invested, to estimate the expenses that
you paid during the six-months ended April 30, 2010. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number under the heading entitled "Expenses Paid
During Period" to estimate the expenses you paid on your account during this
period.

- - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The fourth and fifth data columns in the table below provide information about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense ratio and an assumed rate of return of 5% per year before expenses,
which is not the Fund's actual return. The hypothetical account values and
expenses may not be used to estimate the actual ending account balances or
expenses you paid for the six-month period shown. You may use this information
to compare the ongoing costs of investing in the Fund with the ongoing costs of
investing in other Funds. To do so, compare this 5% hypothetical example with
the 5% hypothetical examples that appear in the shareholder reports of the other
Funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as
redemption fees, if applicable, exchange fees, or sales charges (loads).
Therefore, the fourth and fifth data columns of the table are useful in
comparing ongoing costs only and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.



                                                                           ENDING ACCOUNT

8    MainStay S&P 500 Index Fund



PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

QUESTIONS ANSWERED BY PORTFOLIO MANAGERS FRANCIS J. OK AND LEE BAKER OF MADISON
SQUARE INVESTORS LLC, THE FUND'S SUBADVISOR.

HOW DID MAINSTAY S&P 500 INDEX FUND PERFORM RELATIVE TO ITS PEERS AND ITS
BENCHMARK DURING THE SIX MONTHS ENDED APRIL 30, 2010?

Excluding all sales charges, MainStay S&P 500 Index Fund returned 15.37% for
Investor Class shares and 15.46% for Class A shares for the six months ended
April 30, 2010. Over the same period, the Fund's Class I shares returned 15.54%.
Class A and I shares outperformed--and Investor Class shares performed in line
with--the 15.37% return of the average Lipper(1) S&P 500(R) Index objective fund
during the six-month reporting period. All share classes underperformed the
15.66% return of the S&P 500(R) Index(2) for the six months ended April 30,
2010. Because the Fund incurs operating expenses that the Index does not, the
Fund's net performance will typically lag that of the Index. The S&P 500(R)
Index is the Fund's broad-based securities-market index. See page 5 for Fund
returns with sales charges.

DURING THE REPORTING PERIOD, WHICH INDUSTRIES HAD THE HIGHEST TOTAL RETURNS AND
WHICH HAD THE LOWEST?

During the reporting period, the S&P 500(R) Index industry with the highest
total return was automobiles. Real estate management & development had the
second-highest industry total return, followed
by airlines. During the reporting period, health care technology had the lowest
total return of any indus-try in the Index. Independent power producers & energy
traders had the second-lowest total return, followed by thrifts & mortgage
finance.

DURING THE REPORTING PERIOD, WHICH INDUSTRIES WERE THE STRONGEST CONTRIBUTORS TO
THE FUND'S PERFORMANCE AND WHICH WERE THE WEAKEST CONTRIBUTORS?

On the basis of impact, which takes weightings and total returns into account,
the industry that made the strongest contribution to the Fund's performance was
computers & peripherals. Commercial banks was the second-strongest contributor,
followed by media. The industry that made the weakest contribution to the Fund's
performance was independent power producers & energy traders. The second-weakest
contributor was health care technology, followed by thrifts & mortgage finance.

DURING THE REPORTING PERIOD, WHICH INDIVIDUAL COMPANIES HAD THE HIGHEST TOTAL
RETURNS AND WHICH HAD THE LOWEST TOTAL RETURNS?

Within the S&P 500(R) Index, the company with the highest total return during
the six-month reporting period was communications equipment company JDS
Uniphase. Commercial bank Zions Bancorporation had the second-highest total
return, followed by semiconductor firm Advanced Micro Devices.

During the reporting period, the S&P 500(R) Index stock with the lowest total
return was Motorola, a leading communications equipment company. Software
company McAfee had the second-lowest total return, followed by energy equipment
& services company Diamond Offshore Drilling.

DURING THE REPORTING PERIOD, WHICH INDIVIDUAL STOCKS WERE THE STRONGEST
CONTRIBUTORS TO THE FUND'S ABSOLUTE PERFORMANCE AND WHICH WERE THE WEAKEST
CONTRIBUTORS?

On the basis of impact, which takes weightings and total returns into account,
the stocks that made the greatest positive contributions to the Fund's
performance during the reporting period were computers
& peripherals company Apple, followed by industrial conglomerate General
Electric and diversified financial services company Bank of America. The weakest
contributor was energy giant ExxonMobil, followed by capital markets firm
Goldman Sachs Group and communications company Qualcomm.

WERE THERE ANY CHANGES IN THE MAKEUP OF THE S&P 500(R) INDEX DURING THE
REPORTING PERIOD?

During the six-month reporting period, there were
14 additions to the S&P 500(R) Index and 14 deletions from it. Two significant
additions to the Index based on index weightings were business services firm
Visa and insurance company Berkshire Hathaway. Beverage company Pepsi Bottling
Group was a major deletion during the reporting period. The stock was deleted
from the S&P 500(R) Index when Pepsi Bottling Group was acquired by Pepsico,
which itself is part of the Index.

NOTES TO FINANCIAL STATEMENTS UNAUDITED

NOTE 1--ORGANIZATION AND BUSINESS:

MainStay Funds Trust (the "Trust") is organized as a Delaware Statutory Trust
and is governed by a Declaration of Trust dated April 8, 2009. The Trust is
registered under the Investment Company Act of 1940, as amended (the "1940
Act"), as an open-end management investment company, and is comprised of twenty-
nine funds (collectively referred to as the "Funds"). These financial statements
and notes relate only to the MainStay S&P 500 Index Fund (the "Fund"), a
diversified fund. The Fund is the successor of the MainStay S&P 500 Index Fund,
a series of Eclipse Funds Inc. (the "Predecessor Fund"). The reorganization of
the Predecessor Fund with and into the Fund, which was not subject to
shareholder approval under applicable law, occurred on February 26, 2010. All
information regarding and references to periods prior to the commencement of
operations of the Fund relate to the Predecessor Fund.

The Fund currently offers three classes of shares. Class I shares commenced
operations on January 2, 1991. Class A shares commenced operations on January 2,
2004. Investor Class shares commenced operations on February 28, 2008. Investor
Class and Class A shares are offered at net asset value ("NAV") per share plus
an initial sales charge. No sales charge applies on investments of $1 million or
more (and certain other qualified purchases) in Investor Class and Class A
shares, but a contingent deferred sales charge is imposed on certain redemptions
of such shares within one year of the date of purchase. Class I shares are
offered at NAV and are not subject to a sales charge. Depending upon
eligibility, Investor Class shares may convert to Class A shares and Class A
shares may convert to Investor Class shares. The three classes of shares have
the same voting (except for issues that relate solely to one class), dividend,
liquidation and other rights, and the same terms and conditions. Class I shares
are not subject to a distribution and/or service fee.

The Fund's investment objective is to seek to provide investment results that
correspond to the total return performance (reflecting reinvestment of
dividends) of common stocks in the aggregate, as represented by the S&P 500((R)
Index.

NOTE 2--SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with accounting
principles generally accepted in the United States of America ("GAAP") and
follows the significant accounting policies described below.

(A) SECURITIES VALUATION.  Equity securities are valued at the latest quoted
sales prices as of the close of regular trading on the New York Exchange
("Exchange") (generally 4:00 p.m. Eastern time) on each day the Fund is open for
business ("valuation date"). Securities that are not traded on the valuation
date are valued at the mean of the latest quoted bid and asked prices. Prices
normally are taken from the principal market in which each security trades.
Futures contracts are valued at the last posted settlement price on the market
where such futures are primarily traded. Investments in other mutual funds are
valued at their NAVs as of the close of the Exchange on the valuation date.

Temporary cash investments acquired over 60 days prior to maturity are valued
using the latest bid prices or using valuations based on a matrix system (which
considers such factors as security prices, yields, maturities, and ratings),
both as furnished by independent pricing services. Other temporary cash
investments which mature in 60 days or less ("short-term investments") are
valued at amortized cost. The amortized cost method involves valuing a security
at its cost on the date of purchase and thereafter assuming a constant
amortization to maturity of the difference between the principal amount due at
maturity and cost.

Securities for which market quotations are not readily available are valued by
methods deemed in good faith by the Fund's Board to represent fair value. Equity
and non-equity securities which may be valued in this manner include, but are
not limited to: (i) a security the trading for which has been halted or
suspended; (ii) a debt security that has recently gone into default and for
which there is not a current market quotation; (iii) a security of an issuer
that has entered into a restructuring; (iv) a security that has been de-listed
from a national exchange; (v) a security the market price of which is not
available from an independent pricing source or, if so provided, does not, in
the opinion of the Fund's Manager or Subadvisor, as defined in Note 3(A),
reflect the security's market value; and (vi) a security where the trading on
that security's principal market is temporarily closed at a time when, under
normal conditions, it would be open. At April 30, 2010, the Fund did not hold
securities that were valued in such a manner.

"Fair value" is defined as the price that the Fund would receive upon selling an
investment in an orderly transaction to an independent buyer in the principal or
most advantageous market of the investment. Fair value measurements are
determined within a framework that has established a three-tier hierarchy which
maximizes the use of observable market data and minimizes the use of
unobservable inputs to establish classification of fair value measurements for
disclosure purposes. "Inputs" refer broadly to the assumptions that market
participants would use in pricing the asset or liability, including assumptions
about risk, such as the risk inherent in a particular valuation technique used
to measure fair value using a pricing model and/or the risk inherent in the
inputs for the valuation technique. Inputs may be observable or unobservable.
Observable inputs are inputs that reflect the assumptions market participants
would use in pricing the asset or liability based on market data obtained from
sources independent of the reporting entity. Unobservable inputs are inputs that
reflect the reporting entity's own assumptions about the assumptions market
participants would use in pricing the asset or

24    MainStay S&P 500 Index Fund



liability developed based on the information available in the circumstances. The
inputs or methodology used for valuing securities may not be an indication of
the risks associated with investing in those securities. The three-tier
hierarchy of inputs is summarized in the three broad Levels listed below.

- - Level 1--quoted prices in active markets for identical investments

- - Level 2--other significant observable inputs (including quoted prices for
  similar investments in active markets, interest rates and yield curves,
  prepayment speeds, credit risks, etc.)

- - Level 3--significant unobservable inputs (including the Fund's own assumptions
  about the assumptions that market participants would use in determining the
  fair value of investments)

The aggregate value by input level, as of April 30, 2010, for the Fund's
investments is included at the end of the Fund's Portfolio of Investments.

The valuation techniques used by the Fund to measure fair value during the six-
month period ended April 30, 2010 maximized the use of observable inputs and
minimized the use of unobservable inputs. The Fund may have utilized some of the
following fair value techniques: multi-dimensional relational pricing models,
option adjusted spread pricing and estimating the price that would have
prevailed in a liquid market for an international equity security given
information available at the time of evaluation, when there are significant
events after the close of local foreign markets. For the six-month period ended
April 30, 2010, there have been no changes to the fair value methodologies.

(B) FEDERAL INCOME TAXES.   The Fund's policy is to comply with the requirements
of the Internal Revenue Code of 1986, as amended (the "Internal Revenue Code")
applicable to regulated investment companies and to distribute all of the
taxable income to the shareholders of the Fund within the allowable time limits.
Therefore, no federal income tax provision is required.

Management evaluates its tax positions to determine if the tax positions taken
meet the minimum recognition threshold in connection with accounting for
uncertainties in income tax positions taken or expected to be taken for the
purposes of measuring and recognizing tax liabilities in the financial
statements. Recognition of tax benefits of an uncertain tax position is required
only when the position is "more likely than not" to be sustained assuming
examination by taxing authorities. Management has analyzed the Fund's tax
positions taken on federal income tax returns for all open tax years (current
and prior three tax years), and has concluded that no provision for federal
income tax is required in the Fund's financial statements. The Fund's federal
and state income and federal excise tax returns for tax years for which the
applicable statutes of limitations have not expired are subject to examination
by the Internal Revenue Service and state departments of revenue.

(C) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS.  Dividends and distributions
are recorded on the ex-dividend date. The Fund intends to declare and pay
dividends of net investment income and distributions of net realized capital and
currency gains, if any, annually. Unless the shareholder elects otherwise, all
dividends and distributions are reinvested in the same class of shares of the
Fund, at NAV. Dividends and distributions to shareholders are determined in
accordance with federal income tax regulations and may differ from GAAP.

(D) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  The Fund records security
transactions on the trade date. Realized gains and losses on security
transactions are determined using the identified cost method. Dividend income is
recognized on the ex-dividend date and interest income is accrued as earned
using the effective interest rate method. Discounts and premiums on short-term
investments are accreted and amortized, respectively, on the straight-line
method.

Investment income and realized and unrealized gains and losses on investments of
the Fund are allocated to separate classes of shares pro rata based upon their
relative net assets on the date the income is earned or realized and unrealized
gains and losses are incurred.

(E) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred, except where direct allocations of expenses can be made. Expenses
(other than transfer agent expenses and fees incurred under the shareholder
services plans and the distribution plans further discussed in Note 3(B)) are
allocated to separate classes of shares pro rata based upon their relative NAV
on the date the expenses are incurred. The expenses borne by the Fund, including
those of related parties to the Fund, are shown in the Statement of Operations.

(F) USE OF ESTIMATES.  In preparing financial statements in conformity with
GAAP, management makes estimates and assumptions that affect the reported
amounts and disclosures in the financial statements. Actual results could differ
from those estimates.

(G) REPURCHASE AGREEMENTS.  The Fund may enter into repurchase agreements to
earn income. The Fund may enter into repurchase agreements only with financial
institutions that are deemed by the Manager or Subadvisor to be creditworthy,
pursuant to guidelines established by the Fund's Board. Repurchase agreements
are considered under the 1940 Act to be collateralized loans by a Fund to the
seller secured by the securities transferred to the Fund.

NOTES TO FINANCIAL STATEMENTS UNAUDITED (CONTINUED)


When the Fund invests in repurchase agreements, the Fund's custodian takes
possession of the collateral pledged for investments in such repurchase
agreements. The underlying collateral is valued daily on a mark-to-market basis
to determine that the value, including accrued interest, exceeds the repurchase
price. In the event of the seller's default of the obligation to repurchase, the
Fund has the right to liquidate the collateral and apply the proceeds in
satisfaction of the obligation. Under certain circumstances, in the event of
default or bankruptcy by the other party to the agreement, realization and/or
retention of the collateral may be subject to legal proceedings and possible
realized loss to the Fund.

(H) FUTURES CONTRACTS.  A futures contract is an agreement to purchase or sell a
specified quantity of an underlying instrument at a specified future date and
price, or to make or receive a cash payment based on the value of a financial
instrument (e.g., foreign currency, interest rate, security, or securities
index.) The Fund is subject to equity rate risk in the normal course of
investing in these transactions. The Fund enters into futures contracts for
market exposure. During the period the futures contract is open, changes in the
value of the contract are recognized as unrealized gains or losses by "marking
to market" such contract on a daily basis to reflect the market value of the
contract at the end of each day's trading. The Fund agrees to receive from or
pay to the broker an amount of cash equal to the daily fluctuation in the value
of the contract. Such receipts or payments are known as "variation margin". When
the futures contract is closed, the Fund records a realized gain or loss equal
to the difference between the proceeds from (or cost of) the closing transaction
and the Fund's basis in the contract.

The use of futures contracts involves, to varying degrees, elements of market
risk in excess of the amount recognized in the Statement of Assets and
Liabilities. The contract or notional amounts and variation margin reflect the
extent of the Fund's involvement in open futures positions. Risks arise from the
possible imperfect correlation in movements in the price of futures contracts,
interest rates and the underlying hedged assets, and the possible inability of
counterparties to meet the terms of their contracts. However, the Fund's
activities in futures contracts have minimal counterparty risk as they are
conducted through regulated exchanges that guarantee the futures against default
by the counterparty. The Fund invests in futures contracts to provide an
efficient means of maintaining liquidity while being fully invested in the
market. The Fund's investment in futures contracts and other derivatives may
increase the volatility of the Fund's NAV and may result in a loss to the Fund

(I) SECURITIES LENDING.  In order to realize additional income, the Fund may
engage in securities lending, subject to the limitations set forth in the 1940
Act, and relevant guidance by the staff of the Securities and Exchange
Commission. In the event the Fund does engage in securities lending, the Fund
will lend through its custodian, State Street Bank and Trust Company ("State
Street"). State Street will manage the Fund's cash collateral in accordance with
the Lending Agreement between the Fund and State Street, and indemnify the
Fund's portfolio against counterparty risk. The loans will be collateralized by
cash or securities at least equal at all times to the market value of the
securities loaned. Collateral will consist of U.S. Government securities, cash
equivalents or irrevocable letters of credit. The Fund may bear the risk of
delay in recovery of, or loss of rights in, the securities loaned should the
borrower of the securities experience financial difficulty. The Fund may also
record realized gain or loss on securities deemed sold due to a borrower's
inability to return securities on loan. The Fund will receive compensation for
lending its securities in the form of fees or retain a portion of interest on
the investment of any cash received as collateral. The Fund also will continue
to receive interest and dividends on the securities loaned and any gain or loss
in the market price of the securities loaned that may occur during the term of
the loan will be for the account of the Fund.

Although the Fund and New York Life Investments (as defined in Note 3(A)) have
temporarily suspended securities lending, the Fund and New York Life Investments
reserve the right to reinstitute lending when deemed appropriate. The Fund had
no portfolio securities on loan as of April 30, 2010.

(J) INDEMNIFICATIONS.  Under the Trust's organizational documents, its officers
and trustees are indemnified against certain liabilities that may arise out of
performance of their duties to the Trust. Additionally, in the normal course of
business, the Fund enters into contracts with third-party service providers that
contain a variety of representations and warranties and which provide general
indemnifications. The Fund's maximum exposure under these arrangements is
unknown, as this would involve future claims that may be made against the Fund
that have not yet occurred. Based on experience, management is of the view that
the risk of loss in connection with these potential indemnification obligations
is remote. However, there can be no assurance that material liabilities related
to such obligations will not arise in the future, which could adversely impact
the Fund.

(K) QUANTITATIVE DISCLOSURE OF DERIVATIVE HOLDINGS.  The following tables show
additional disclosures about the Fund's derivative and hedging activities,
including how such activities are accounted for and their effect on the Fund's
financial positions, performance and cash flows. These derivatives are not
accounted for as hedging instruments.

NOTES TO FINANCIAL STATEMENTS UNAUDITED (CONTINUED)



Life Investments and the Subadvisor, New York Life Investments pays for the
services of the Subadvisor.

The Fund pays the Manager a monthly fee for services performed and facilities
furnished at an annual rate of the Fund's average daily net assets as follows:
0.25% on assets up to $1 billion, 0.225% on assets from $1 billion to $2
billion, 0.215% on assets from $2 billion to $3 billion, and 0.20% on assets in
excess of $3 billion. The effective management fee rate (exclusive of any
applicable waivers/ reimbursements) was 0.24% for the six-month period ended
April 30, 2010.

Effective August 1, 2009, New York Life Investments entered into a written
expense limitation agreement under which it has agreed to waive a portion of the
management fee or reimburse expenses to the extent necessary to ensure that the
total ordinary operating expenses (total ordinary operating expenses excludes
taxes, interest, litigation, extraordinary expenses, brokerage, other
transaction expenses relating to the purchase or sale of portfolio investments,
and the fees and expenses of any other funds in which the Fund invests) for the
Fund's Class A shares do not exceed 0.60% of its average daily net assets. New
York Life Investments will apply an equivalent waiver or reimbursement, in an
equal number of basis points, to the other share classes of the Fund. This
expense limitation agreement expires on February 28, 2011 and is reviewed
annually by the Board in connection with its review of the Fund's investment
advisory agreements. Based on its review, the Board may agree to maintain,
modify or terminate the agreement.

Additionally, effective August 1, 2009, New York Life Investments has agreed to
voluntarily reimburse the expenses of the Investor Class shares of the Fund so
that the total annual operating expenses of Investor Class shares do not exceed
0.70%. This voluntary waiver may be discontinued at any time.

For the six-month period ended April 30, 2010, New York Life Investments earned
fees from the Fund in the amount of $1,633,332 and waived/reimbursed its fees in
the amount of $1,128,037.

State Street, 1 Lincoln Street, Boston, Massachusetts 02111, provides sub-
administration and sub-accounting services to the Fund pursuant to an agreement
with New York Life Investments. These services include calculating the daily
NAVs of the Fund, maintaining the general ledger and sub-ledger accounts for the
calculation of the Fund's respective NAVs, and assisting New York Life
Investments in conducting various aspects of the Fund's administrative
operations. For providing these services to the Fund, State Street is
compensated by New York Life Investments.

(B) DISTRIBUTION AND SERVICE FEES.  The Trust, on behalf of the Fund, has
entered into a Distribution Agreement with NYLIFE Distributors LLC (the
"Distributor"), an indirect, wholly-owned subsidiary of New York Life. The Fund
has adopted distribution plans, (the "Plans") in accordance with the provisions
of Rule 12b-1 under the 1940 Act.

Pursuant to the Investor Class and Class A Plans, the Distributor receives a
monthly distribution fee from the Investor Class and Class A shares at an annual
rate of 0.25% of the average daily net assets of the Investor Class and Class A
shares for distribution or service activities as designated by the Distributor.
Class I shares are not subject to a distribution or service fee.

The Plans provide that the distribution and service fees are payable to the
Distributor regardless of the amounts actually expended by the Distributor for
distribution of the Fund's shares and service activities.

(C) SALES CHARGES.  The Fund was advised by the Distributor that the amount of
sales charges retained on sales of Investor Class and Class A shares were $4,139
and $3,873, respectively, for the six-month period ended April 30, 2010. The
Fund was also advised that the Distributor retained contingent deferred sales
charges on redemptions of Investor Class and Class A shares of $27 and $362,
respectively for the six-month period ended April 30, 2010.

(D) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT.  NYLIM
Service Company LLC, an affiliate of New York Life Investments, is the Fund's
transfer, dividend disbursing and shareholder servicing agent pursuant to an
agreement between NYLIM Service Company LLC and the Trust. NYLIM Service Company
LLC has entered into an agreement with Boston Financial Data Services, Inc.
("BFDS") pursuant to which BFDS performs certain transfer agent services on
behalf of NYLIM Service Company LLC. Transfer agent expenses incurred by the

(E) SMALL ACCOUNT FEE.  Shareholders with small accounts adversely impact the
cost of providing transfer agency services. In an effort to reduce total
transfer agency expenses, the Fund has implemented a small account fee on
certain types of accounts. Certain shareholders with an account balance of less
than $1,000 are charged an annual per account fee of $20 (assessed semi-
annually). These fees are included in transfer agent fees shown on the Statement
of Operations.

(a) In addition to any automatic conversion features described above in Note 1
    with respect to Investor Class, Class A and B shares, you generally may also
    elect to convert your shares on a voluntary basis into another share class
    of the same fund for which you are eligible. However, the following
    limitations apply:

- - Investor Class and Class A shares that remain subject to a CDSC are ineligible
  for a voluntary conversion; and

- - All Class B and C shares are ineligible for a voluntary conversion.

These limitations do not impact any automatic conversion features described in
Note 1 with respect to Investor Class, Class A and B shares.

An investor or an investor's financial intermediary may contact the Fund to
request a voluntary conversion between shares classes of the same Fund. You may
be required to provide sufficient information to establish eligibility to
convert to the new share class. All permissible conversions will be made on the
basis of the relevant NAVs of the two classes without the imposition of any
sales load, fee or other charge. If you fail to remain eligible for the new
share class, you may automatically be converted back to your original share
class, or into another share class, if appropriate.

NOTE 9--NEW ACCOUNTING PRONOUNCEMENT:

In January 2010, the Financial Accounting Standards Board ("FASB") issued
Accounting Standards Update ("ASU") No. 2010-06 "Improving Disclosures about
Fair Value Measurements". ASU 2010-06 requires reporting entities to make new
disclosures about amount and reasons for significant transfers in and out of
Level 1 and Level 2 fair value measurements and input and valuation techniques
used to measure fair value for both recurring and nonrecurring fair value
measurements that fall in either Level 2 or Level 3, and information on
purchased, sales, issuances, and settlements in the roll forward of activity in
Level 3 fair value measures. The new and revised disclosure requirements are
effective for interim and annual reporting periods beginning after December 15,
2009 except for the disclosures about purchased, sales, issuances, and
settlements in the roll forward of activity in Level 3 fair value measures,
which are effective for fiscal years beginning after December 15, 2010.  As of
April 30, 2010, the Fund has adopted ASU 2010-06. The adoption of ASU 2010-06
has not impacted the amounts reported in the financial statements; however,
there are additional disclosures in the Portfolio of Investments.

NOTE 10--SUBSEQUENT EVENTS:

In connection with the preparation of the financial statements of the Fund as of
and for the fiscal six-month period ended April 30, 2010, events and
transactions subsequent to April 30, 2010 through the date the financial
statements were issued have been evaluated by the Fund's management for possible
adjustment and/or disclosure. No subsequent events requiring financial statement
adjustment or disclosure have been identified.

        MESSAGE FROM THE PRESIDENT AND SEMIANNUAL REPORT

        Unaudited - April 30, 2010



MESSAGE FROM THE PRESIDENT

During the six months ended April 30, 2010, stock and bond markets generally
advanced, despite some volatility in January and February. Domestic small-cap
stocks were particularly strong, and U.S. stocks at all capitalization levels
provided double digit returns. Value stocks outpaced growth stocks for companies
of all sizes during the reporting period.

International stocks provided positive returns overall, but results varied
widely by country. Concerns about Greece's ability to meet its debt obligations
led many investors to abandon their holdings in Greece and question their
investments in several peripheral European nations where perceived risk had
increased. For the six-month reporting period, equities in the Far East
(including Japan) tended to be stronger than those in Europe.

The economic recovery in the United States continued. Real gross domestic
product advanced in the first quarter of 2010, though at a slower pace than in
the fourth quarter of 2009. The Federal Open Market Committee kept the targeted
federal funds rate at a historically low level throughout the reporting period,
which prompted many investors to leave the safety of U.S. Treasury securities in
search of higher yield.

In the high-yield bond market, lower-rated credits tended to be the strongest
performers. With investment-grade investors crossing into high-yield territory,
however, the highest-rated high-yield credits also saw strong demand. In the
municipal market, new-issue supply was reduced by government incentives that
encouraged municipal issuers to raise funds in the taxable market. In the
leveraged-loan market, new issuance strengthened, but extensive repayments
caused the market as a whole to contract.


Throughout the six-month reporting period, MainStay's portfolio managers sought
to make the most of market conditions within the investment strategies and risk
parameters of their respective Funds. While individual markets and Fund results
may vary, our pursuit of competitive returns over full market cycles has never
changed.

The information that follows provides a closer look
at the securities, strategies and market conditions that affected your MainStay
Fund(s) during the six months ended April 30, 2010. Of course, past performance
is no guarantee of future results. Even in a rising market, we believe that
maintaining a long-term perspective can be valuable. At MainStay, we believe
that in all markets, broad diversification, gradual allocation adjustments and
regular portfolio reviews can help guide you toward your long-range financial
goals.

We thank you for choosing MainStay Funds, and we look forward to serving your
investment needs for many years to come.

Sincerely,

/s/ STEPHEN P. FISHER

Stephen P. Fisher
President

6    MainStay Short Term Bond Fund



COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY SHORT TERM BOND FUND
(UNAUDITED)
- --------------------------------------------------------------------------------

The example below is intended to describe the fees and expenses borne by
shareholders during the six-month period from November 1, 2009, to April 30,
2010, and the impact of those costs on your investment.

EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, exchange fees, and sales charges (loads) on
purchases (as applicable), and (2) ongoing costs, including management fees,
distribution and/or service (12b-1) fees, and other Fund expenses (as
applicable). This example is intended to help you understand your ongoing costs
(in dollars) of investing in the Fund and to compare these costs with the
ongoing costs of investing in other mutual funds. The example is based on an
investment of $1,000 made at the beginning of the six-month period and held for
the entire period from November 1, 2009, to April 30, 2010.

This example illustrates your Fund's ongoing costs in two ways:

- - ACTUAL EXPENSES
The second and third data columns in the table below provide information about
actual account values and actual expenses. You may use the information in these
columns, together with the amount you invested, to estimate the expenses that
you paid during the six-months ended April 30, 2010. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number under the heading entitled "Expenses Paid
During Period" to estimate the expenses you paid on your account during this
period.

- - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The fourth and fifth data columns in the table below provide information about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense ratio and an assumed rate of return of 5% per year before expenses,
which is not the Fund's actual return. The hypothetical account values and
expenses may not be used to estimate the actual ending account balances or
expenses you paid for the six-month period shown. You may use this information
to compare the ongoing costs of investing in the Fund with the ongoing costs of
investing in other Funds. To do so, compare this 5% hypothetical example with
the 5% hypothetical examples that appear in the shareholder reports of the other
Funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as
redemption fees, if applicable, exchange fees, or sales charges (loads).
Therefore, the fourth and fifth data columns of the table are useful in
comparing ongoing costs only and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.

   represents the actual expenses incurred during the one-half year period.

8    MainStay Short Term Bond Fund



PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

QUESTIONS ANSWERED BY PORTFOLIO MANAGERS CLAUDE ATHAIDE, PHD, CFA, GARY
GOODENOUGH AND JAMES RAMSAY, CFA, OF MACKAY SHIELDS LLC, THE FUND'S SUBADVISOR.

HOW DID MAINSTAY SHORT TERM BOND FUND PERFORM RELATIVE TO ITS PEERS AND ITS
BENCHMARK DURING THE SIX MONTHS ENDED APRIL 30, 2010?

Excluding all sales charges, MainStay Short Term Bond Fund returned 0.29% for
Investor Class shares and 0.54% for Class A shares for the six months ended
April 30, 2010. Over the same period, the Fund's Class I shares returned 0.77%.
All share classes underperformed the 1.33% return of the average Lipper(1) short
U.S. government fund, the 1.26% return of the Barclays Capital U.S. 1-3 Year
Government/Credit Index(2) and the 0.78% return of the Citigroup 1-3 Year U.S.
Treasury Agency Index(3) for the six months ended April 30, 2010. The Barclays
Capital U.S. 1-3 Year Government/Credit Index is the Fund's broad-based
securities-market index. See page 5 for Fund returns with sales charges.

WHAT FACTORS CONTRIBUTED TO THE FUND'S RELATIVE PERFORMANCE DURING THE REPORTING
PERIOD?

Real gross domestic product (GDP) grew at an annual rate of 5.6% in the fourth
quarter of 2009, with inventory adjustment and personal consumption contributing
3.8% and 1.16%, respectively. In the first quarter of 2010, real GDP grew an
annualized 3.0%, with personal consumption growing at 3.5%. The labor market
improved during the reporting period, as nonfarm payrolls increased 573,000
during the first four months of 2010.

Credit spreads(4) tightened during the reporting period, as investors' appetite
for risk remained firm. An 8% decline in the S&P 500(R) Index(5) beginning in
the second half
of January 2010 was shrugged off, and stocks rallied, reaching new highs for the
period by the end of April.

With conditions improving in the financial markets, the Federal Reserve ended
most of its emergency liquidity programs that had been initiated since December
2007. These included the Term Auction Facility, the Term Securities Lending
Facility, the Primary Dealer Credit Facility, the Commercial Paper Funding
Facility and the Asset Backed Commercial Paper Money Market Fund Liquidity
Facility. The Federal Reserve also announced that the Term Asset-Backed
Securities Loan Facility (TALF) will expire at the end of June 2010. In
addition, in March 2010, the Federal Reserve completed its purchase of $1.25
trillion of agency mortgage-backed securities and $175 billion of agency debt.

HOW DID THE FUND INVEST DURING THE REPORTING PERIOD?

During the fourth quarter of 2009, we positioned the Fund for lower interest
rates and a flatter yield curve.(6) However, interest rates rose in December
2009, and the yield curve steepened. These developments detracted from the
Fund's performance relative to the Barclays Capital U.S. 1-3 Year
Government/Credit Index.

In the first quarter of 2010, we increased the Fund's allocation to corporate
bonds from 2.2% of net assets to 22.2%, while we reduced the percentage of
Treasury securities in the Fund from 68.6% to 50.5%.

WHICH MARKET SEGMENTS WERE PARTICULARLY STRONG DURING THE REPORTING PERIOD AND
WHICH ONES WERE WEAK?

The strongest market segments from a total return perspective were commercial
mortgage-backed securities with maturities of up to three years and 1-3 year
corporate bonds. Although all segments of the short-term market provided
positive returns, the weakest market segments were 1-3 year Treasury and agency
securities.

HOW WAS THE FUND POSITIONED AT THE END OF THE REPORTING PERIOD?

Despite the recovery in risk appetite during the latter half of the reporting
period, we remained defensive and refrained from further increases in the Fund's
exposure to corporate bonds. Although we believe that the worst of the economic
contraction may be out of the way, talk of an economic recovery is, in our
opinion, still premature.

4. The terms "spread" and "yield spread" may refer to the difference in yield
   between a security or type of security and comparable U.S. Treasury issues.
   The terms may also refer to the difference in yield between two specific
   securities or types of securities at a given time.
5. The S&P 500(R) Index is a trademark of the McGraw-Hill Companies, Inc., and
   is widely recognized as the standard for measuring large-cap U.S. stock

   gains. An investment cannot be made directly in an index.
6. The yield curve is a line that plots the yields of various securities of
   similar quality--typically U.S. Treasury issues--across a range of
   maturities. The U.S. Treasury yield curve serves as a benchmark for other
   debt and is used in economic forecasting.

NOTES TO FINANCIAL STATEMENTS UNAUDITED

NOTE 1--ORGANIZATION AND BUSINESS:

MainStay Funds Trust (the "Trust") is organized as a Delaware Statutory Trust
and is governed by a Declaration of Trust dated April 8, 2009. The Trust is
registered under the Investment Company Act of 1940, as amended (the "1940
Act"), as an open-end management investment company, and is comprised of twenty-
nine funds (collectively referred to as the "Funds"). These financial statements
and notes relate only to the MainStay Short Term Bond Fund (the "Fund"), a
diversified fund. The Fund is the successor of the MainStay Short Term Bond
Fund, a series of Eclipse Funds Inc. (the "Predecessor Fund"). The
reorganization of the Predecessor Fund with and into the Fund, which was not
subject to shareholder approval under applicable law, occurred on February 26,
2010. All information regarding and references to periods prior to the
commencement of operations of the Fund relate to the Predecessor Fund.

The Fund currently offers three classes of shares. Class I shares commenced
operations on January 2, 1991. Class A shares commenced operations on January 2,
2004. Investor Class shares commenced operations on February 28, 2008. Investor
Class and Class A shares are offered at net asset value ("NAV") per share plus
an initial sales charge. No sales charge applies on investments of $1 million or
more (and certain other qualified purchases) in Investor Class and Class A
shares, but a contingent deferred sales charge is imposed on certain redemptions
of such shares within one year of the date of purchase. Class I shares are
offered at NAV and are not subject to a sales charge. Depending upon
eligibility, Investor Class shares may convert to Class A shares and Class A
shares may convert to Investor Class shares. The three classes of shares have
the same voting (except for issues that relate solely to one class), dividend,
liquidation and other rights, and the same terms and conditions. Class I shares
are not subject to a distribution and/or service fee.

The Fund's investment objective is to seek to maximize total return, consistent
with liquidity, preservation of capital and investment in short-term debt
securities.

NOTE 2--SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with accounting
principles generally accepted in the United States of America ("GAAP") and
follows the significant accounting policies described below.

(A) SECURITIES VALUATION.  Debt securities are valued at prices supplied by a
pricing agent or broker selected by the Fund's Manager (as defined in Note 3(A))
in consultation with the Fund's Subadvisor, if any (as defined in Note 3(A)),
whose prices reflect broker/dealer supplied valuations and electronic data
processing techniques, if such prices are deemed by the Fund's Manager, in
consultation with the Fund's Subadvisor, if any, to be representative of market
values, at the regular close of trading of the New York Stock Exchange
("Exchange") (generally 4:00 p.m. Eastern time) on each day the Fund is open for
business ("valuation date"). Investments in other mutual funds are valued at
their NAVs as of the close of the Exchange on the valuation date.

Temporary cash investments acquired over 60 days prior to maturity are valued
using the latest bid prices or using valuations based on a matrix system (which
considers such factors as security prices, yields, maturities, and ratings),
both as furnished by independent pricing services. Other temporary cash
investments which mature in 60 days or less ("short-term investments") are
valued at amortized cost. The amortized cost method involves valuing a security
at its cost on the date of purchase and thereafter assuming a constant
amortization to maturity of the difference between the principal amount due at
maturity and cost.

Securities for which market quotations are not readily available are valued by
methods deemed in good faith by the Fund's Board to represent fair value. Equity
and non-equity securities which may be valued in this manner include, but are
not limited to: (i) a security the trading for which has been halted or
suspended; (ii) a debt security that has recently gone into default and for
which there is not a current market quotation; (iii) a security of an issuer
that has entered into a restructuring; (iv) a security that has been de-listed
from a national exchange; (v) a security the market price of which is not
available from an independent pricing source or, if so provided, does not, in
the opinion of the Fund's Manager or Subadvisor, as defined in Note 3(A),
reflect the security's market value; and (vi) a security where the trading on
that security's principal market is temporarily closed at a time when, under
normal conditions, it would be open. At April 30, 2010, the Fund did not hold
securities that were valued in such a manner.

"Fair value" is defined as the price that the Fund would receive upon selling an
investment in an orderly transaction to an independent buyer in the principal or
most advantageous market of the investment. Fair value measurements are
determined within a framework that has established a three-tier hierarchy which
maximizes the use of observable market data and minimizes the use of
unobservable inputs to establish classification of fair value measurements for
disclosure purposes. "Inputs" refer broadly to the assumptions that market
participants would use in pricing the asset or liability, including assumptions
about risk, such as the risk inherent in a particular valuation technique used
to measure fair value using a pricing model and/or the risk inherent in the
inputs for the valuation technique. Inputs may be observable or unobservable.
Observable inputs are inputs that reflect the assumptions market participants
would use in pricing the asset or liability based on market data obtained from
sources independent of the reporting entity. Unobservable inputs are inputs that
reflect the reporting entity's own assumptions about the assumptions market
participants would use in pricing the asset or liability developed based on the
information available in

18    MainStay Short Term Bond Fund



the circumstances. The inputs or methodology used for valuing securities may not
be an indication of the risks associated with investing in those securities. The
three-tier hierarchy of inputs is summarized in the three broad Levels listed
below.

- - Level 1--quoted prices in active markets for identical investments

- - Level 2--other significant observable inputs (including quoted prices for
  similar investments in active markets, interest rates and yield curves,
  prepayment speeds, credit risks, etc.)

- - Level 3--significant unobservable inputs (including the Fund's own assumptions
  about the assumptions that market participants would use in determining the
  fair value of investments)

The aggregate value by input level, as of April 30, 2010, for the Fund's
investments is included at the end of the Fund's Portfolio of Investments.

The valuation techniques used by the Fund to measure fair value during the six-
month period ended April 30, 2010 maximized the use of observable inputs and
minimized the use of unobservable inputs. The Fund may have utilized some of the
following fair value techniques: multi-dimensional relational pricing models,
option adjusted spread pricing and estimating the price that would have
prevailed in a liquid market for an international equity security given
information available at the time of evaluation, when there are significant
events after the close of local foreign markets. For the six-month period ended
April 30, 2010, there have been no changes to the fair value methodologies.

(B) FEDERAL INCOME TAXES.  The Fund's policy is to comply with the requirements
of the Internal Revenue Code of 1986, as amended (the "Internal Revenue Code")
applicable to regulated investment companies and to distribute all of the
taxable income to the shareholders of the Fund within the allowable time limits.
Therefore, no federal income tax provision is required.

Management evaluates its tax positions to determine if the tax positions taken
meet the minimum recognition threshold in connection with accounting for
uncertainties in income tax positions taken or expected to be taken for the
purposes of measuring and recognizing tax liabilities in the financial
statements. Recognition of tax benefits of an uncertain tax position is required
only when the position is "more likely than not" to be sustained assuming
examination by taxing authorities. Management has analyzed the Fund's tax
positions taken on federal income tax returns for all open tax years (current
and prior three tax years), and has concluded that no provision for federal
income tax is required in the Fund's financial statements. The Fund's federal
and state income and federal excise tax returns for tax years for which the
applicable statutes of limitations have not expired are subject to examination
by the Internal Revenue Service and state departments of revenue.

(C) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS.  Dividends and distributions
are recorded on the ex-dividend date. The Fund intends to declare and pay
dividends of net investment income monthly and distributions of net realized
capital and currency gains, if any, annually, Unless the shareholder elects
otherwise, all dividends and distributions are reinvested in the same class of
shares of the Fund, at NAV. Dividends and distributions to shareholders are
determined in accordance with federal income tax regulations and may differ from
GAAP.

(D) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  The Fund records security
transactions on the trade date. Realized gains and losses on security
transactions are determined using the identified cost method and include gains
and losses from repayments of principal on mortgage-backed securities. Interest
income is accrued as earned using the effective interest rate method. Discounts
and premiums on securities purchased, other than short-term investments, for the
Fund are accreted and amortized, respectively, on the effective interest rate
method over the life of the respective securities or, in the case of a callable
security, over the period to the first date of call. Discounts and premiums on
short-term investments are accreted and amortized, respectively, on the
straight-line method. Income from payment-in-kind securities is recorded daily
based on the effective interest method of accrual.

Investment income and realized and unrealized gains and losses on investments of
the Fund are allocated to separate classes of shares pro rata based upon their
relative net assets on the date the income is earned or realized and unrealized
gains and losses are incurred.

(E) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred, except where direct allocations of expenses can be made. Expenses
(other than transfer agent expenses and fees incurred under the shareholder
services plans and the distribution plans further discussed in Note 3(B)) are
allocated to separate classes of shares pro rata based upon their relative NAV
on the date the expenses are incurred. The expenses borne by the Fund, including
those of related parties to the Fund, are shown in the Statement of Operations.

(F) USE OF ESTIMATES.  In preparing financial statements in conformity with
GAAP, management makes estimates and assumptions that affect the reported
amounts and disclosures in the financial statements. Actual results could differ
from those estimates.

(G) REPURCHASE AGREEMENTS.  The Fund may enter into repurchase agreements to
earn income. The Fund may enter into repurchase agreements only with financial
institutions that are deemed by the Manager or Subadvisor to

                                                   mainstayinvestments.com    19



NOTES TO FINANCIAL STATEMENTS UNAUDITED (CONTINUED)



be creditworthy, pursuant to guidelines established by the Fund's Board.
Repurchase agreements are considered under the 1940 Act to be collateralized
loans by a Fund to the seller secured by the securities transferred to the Fund.

When the Fund invests in repurchase agreements, the Fund's custodian takes
possession of the collateral pledged for investments in such repurchase
agreements. The underlying collateral is valued daily on a mark-to-market basis
to determine that the value, including accrued interest, exceeds the repurchase
price. In the event of the seller's default of the obligation to repurchase, the
Fund has the right to liquidate the collateral and apply the proceeds in
satisfaction of the obligation. Under certain circumstances, in the event of
default or bankruptcy by the other party to the agreement, realization and/or
retention of the collateral may be subject to legal proceedings and possible
realized loss to the Fund.

(H) MORTGAGE DOLLAR ROLLS.  The Fund may enter into mortgage dollar roll ("MDR")
transactions in which it sells mortgage-backed securities ("MBS") from its
portfolio to a counterparty from whom it simultaneously agrees to buy a similar
security on a delayed delivery basis. The MDR transactions of the Fund are
classified as purchase and sale transactions. The securities sold in connection
with the MDRs are removed from the portfolio and a realized gain or loss is
recognized. The securities the Fund has agreed to acquire are included at market
value in the Portfolio of Investments and liabilities for such purchase
commitments are included as payables for investments purchased. During the roll
period, the Fund foregoes principal and interest paid on the securities. The
Fund is compensated by the difference between the current sales price and the
forward price for the future as well as by the earnings on the cash proceeds of
the initial sale. MDRs may be renewed without physical delivery of the
securities subject to the contract. The Fund maintains liquid assets from its
portfolio having a value not less than the repurchase price, including accrued
interest. MDR transactions involve certain risks, including the risk that the
MBS returned to the Fund at the end of the roll, while substantially similar,
could be inferior to what was initially sold to the counterparty.

(I) SECURITIES LENDING.  In order to realize additional income, the Fund may
engage in securities lending, subject to the limitations set forth in the 1940
Act, and relevant guidance by the staff of the Securities and Exchange
Commission. In the event the Fund does engage in securities lending, the Fund
will lend through its custodian, State Street Bank and Trust Company ("State
Street"). State Street will manage the Fund's cash collateral in accordance with
the Lending Agreement between the Fund and State Street, and indemnify the
Fund's portfolio against counterparty risk. The loans will be collateralized by
cash or securities at least equal at all times to the market value of the
securities loaned. Collateral will consist of U.S. Government securities, cash
equivalents or irrevocable letters of credit. The Fund may bear the risk of
delay in recovery of, or loss of rights in, the securities loaned should the
borrower of the securities experience financial difficulty. The Fund may also
record realized gain or loss on securities deemed sold due to a borrower's
inability to return securities on loan. The Fund will receive compensation for
lending its securities in the form of fees or retain a portion of interest on
the investment of any cash received as collateral. The Fund also will continue
to receive interest and dividends on the securities loaned and any gain or loss
in the market price of the securities loaned that may occur during the term of
the loan will be for the account of the Fund.

Although the Fund and New York Life Investments (as defined in Note 3(A)) have
temporarily suspended securities lending, the Fund and New York Life Investments
reserve the right to reinstitute lending when deemed appropriate. The Fund had
no portfolio securities on loan as of April 30, 2010.

(J) CONCENTRATION OF RISK.  The ability of issuers of debt securities held by
the Fund to meet their obligations may be affected by economic or political
developments in a specific country, industry or region.

(K) INDEMNIFICATIONS.  Under the Trust's organizational documents, its officers
and trustees are indemnified against certain liabilities that may arise out of
performance of their duties to the Trust. Additionally, in the normal course of
business, the Fund enters into contracts with third-party service providers that
contain a variety of representations and warranties and which provide general
indemnifications. The Fund's maximum exposure under these arrangements is
unknown, as this would involve future claims that may be made against the Fund
that have not yet occurred. Based on experience, management is of the view that
the risk of loss in connection with these potential indemnification obligations
is remote. However, there can be no assurance that material liabilities related
to such obligations will not arise in the future, which could adversely impact
the Fund.

NOTE 3--FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER AND SUBADVISOR.  New York Life Investment Management LLC ("New York
Life Investments" or "Manager"), a registered investment adviser and an
indirect, wholly-owned subsidiary of New York Life Insurance Company ("New York
Life"), serves as the Fund's Manager, pursuant to a Management Agreement, as
amended ("Management Agreement"). The Manager provides offices, conducts
clerical, recordkeeping and bookkeeping services, and keeps most of the
financial and accounting records required to be maintained by the Fund. Except
for the portion of salaries and expenses that are the responsibility of the
Fund, the Manager also pays the salaries and expenses of all personnel
affiliated with the Fund and the operational expenses of the Fund. MacKay

Shields LLC (the "Subadvisor"), a registered investment adviser and an indirect,
wholly-owned subsidiary of New York Life, serves as Subadvisor to the Fund and
is responsible for the day-to-day portfolio management of the Fund. Pursuant to
the terms of a Subadvisory Agreement between New York Life Investments and the
Subadvisor, New York Life Investments pays for the services of the Subadvisor.

The Fund pays the Manager a monthly fee for services performed and facilities
furnished at an annual rate of the Fund's average daily net assets as follows:
0.60% on assets up to $500 million and 0.575% on assets in excess of $500
million. The effective management fee rate (exclusive of any applicable
waivers/reimbursements) was 0.60% for the six-month period ended April 30, 2010.

Effective August 1, 2009, New York Life Investments entered into a written
expense limitation agreement under which it has agreed to waive a portion of the
management fee or reimburse expenses to the extent necessary so that the total
ordinary operating expenses (total ordinary operating expenses excludes taxes,
interest, litigation, extraordinary expenses, brokerage, other transaction
expenses relating to the purchase or sale of portfolio investments, and the fees
and expenses of any other funds in which the Fund invests) for the Fund's Class
A shares do not exceed 0.93% of its average daily net assets. New York Life
Investments will apply an equivalent waiver or reimbursement, in an equal number
of basis points, to the other share classes of the Fund. This agreement expires
on February 28, 2011 and is reviewed annually by the Board in connection with
its review of the Fund's investment advisory agreements. Based on its review,
the Board may agree to maintain, modify or terminate the agreement.

For the six-month period ended April 30, 2010, New York Life Investments earned
fees from the Fund in the amount of $383,738 and waived its fees in the amount
of $122,139.

State Street, 1 Lincoln Street, Boston, Massachusetts 02111, provides sub-
administration and sub-accounting services to the Fund pursuant to an agreement
with New York Life Investments. These services include calculating the daily
NAVs of the Fund, maintaining the general ledger and sub-ledger accounts for the
calculation of the Fund's respective NAVs, and assisting New York Life
Investments in conducting various aspects of the Fund's administrative
operations. For providing these services to the Fund, State Street is
compensated by New York Life Investments.

(B) DISTRIBUTION AND SERVICE FEES.  The Trust, on behalf of the Fund, has
entered into a Distribution Agreement with NYLIFE Distributors LLC (the
"Distributor"), an indirect, wholly-owned subsidiary of New York Life. The Fund
has adopted distribution plans, (the "Plans") in accordance with the provisions
of Rule 12b-1 under the 1940 Act.

Pursuant to the Investor Class and Class A Plans, the Distributor receives a
monthly distribution fee from the Investor Class and Class A shares at an annual
rate of 0.25% of the average daily net assets of the Investor Class and Class A
shares for distribution or service activities as designated by the Distributor.
Class I shares are not subject to a distribution or service fee.

The Plans provide that the distribution and service fees are payable to the
Distributor regardless of the amounts actually expended by the Distributor for
distribution of the Fund's shares and service activities.

(C) SALES CHARGES.  The Fund was advised by the Distributor that the amount of
sales charges retained on sales of Investor Class and Class A shares were $1,201
and $5,013, respectively, for the six-month period ended April 30, 2010. The
Fund was also advised that the Distributor retained contingent deferred sales
charges on redemptions of Investor Class and Class A of $2 and $144,
respectively for the six-month period ended April 30, 2010.

(D) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT.  NYLIM
Service Company LLC, an affiliate of New York Life Investments, is the Fund's
transfer, dividend disbursing and shareholder servicing agent pursuant to an
agreement between NYLIM Service Company LLC and the Trust. NYLIM Service Company
LLC has entered into an agreement with Boston Financial Data Services, Inc.
("BFDS") pursuant to which BFDS performs certain transfer agent services on
behalf of NYLIM Service Company LLC. Transfer agent expenses incurred by the
Fund for the six-month period ended April 30, 2010, were as follows:

<Table>
                                    
Investor Class                         $ 9,396
- ----------------------------------------------
Class A                                 25,304
- ----------------------------------------------
Class I                                 39,734
- ----------------------------------------------

</Table>


(E) SMALL ACCOUNT FEE.  Shareholders with small accounts adversely impact the
cost of providing transfer agency services. In an effort to reduce total
transfer agency expenses, the Fund has implemented a small account fee on
certain types of accounts. Certain shareholders with an account balance of less
than $1,000 are charged an annual per account fee of $20 (assessed semi-
annually). These fees are included in transfer agent fees shown on the Statement
of Operations.

(a) In addition to any automatic conversion features
    described above in Note 1 with respect to Investor
    Class and Class A, you generally may also elect to
    convert your shares on a voluntary basis into
    another share class of the same fund for which you
    are eligible. However, the following limitations
    apply:

</Table>



  - Investor Class and Class A shares that remain subject to a CDSC are
    ineligible for a voluntary conversion; and

  - All Class C shares are ineligible for a voluntary conversion.

These limitations do not impact any automatic conversion features described in
Note 1 with respect to Investor Class and Class A shares.

An investor or an investor's financial intermediary may contact the Fund to
request a voluntary conversion between shares classes of the same Fund. You may
be required to provide sufficient information to establish eligibility to
convert to the new share class. All permissible conversions will be made on the
basis of the relevant NAVs of the two classes without the imposition of any
sales load, fee or other charge. If you fail to remain eligible for the new
share class, you may automatically be converted back to your original share
class, or into another share class, if appropriate.

NOTE 9--NEW ACCOUNTING PRONOUNCEMENT:

In January 2010, the Financial Accounting Standards Board ("FASB") issued
Accounting Standards Update ("ASU") No. 2010-06 "Improving Disclosures about
Fair Value Measurements". ASU 2010-06 requires reporting entities to make new
disclosures about amount and reasons for significant transfers in and out of
Level 1 and Level 2 fair value measurements and input and valuation techniques
used to measure fair value for both recurring and nonrecurring fair value
measurements that fall in either Level 2 or Level 3, and information on
purchased, sales, issuances, and settlements in the roll forward of activity in
Level 3 fair value measures. The new and revised disclosure requirements are
effective for interim and annual reporting periods beginning after December 15,
2009 except for the disclosures about purchased, sales, issuances, and
settlements in the roll forward of activity in Level 3 fair value measures,
which are effective for fiscal years beginning after December 15, 2010. As of
April 30, 2010, the Fund has adopted ASU 2010-06. The adoption of ASU 2010-06
has not impacted the amounts reported in the financial statements; however,
there are additional disclosures in the Portfolio of Investments.

NOTE 10--SUBSEQUENT EVENTS:

In connection with the preparation of the financial statements of the Fund as of
and for the fiscal six-month period ended April 30, 2010, events and
transactions subsequent to April 30, 2010 through the date the financial
statements were issued have been evaluated by the Fund's management for possible
adjustment and/or disclosure. No subsequent events requiring financial statement
adjustment or disclosure have been identified.
