MESSAGE FROM
THE PRESIDENT

During the six months ended April 30, 2005, the U.S. stock market advanced,
though its progress was uneven. The market generally climbed from November
through the end of 2004, hesitated in January 2005, climbed again until early
March, and then slipped back for much of the remainder of the reporting period.

The Federal Open Market Committee raised the targeted federal funds rate at all
four of its meetings during the reporting period, with a 25 basis point increase
on each occasion. That brought the targeted federal funds rate from 1.75% at the
beginning of the reporting period to 2.75% at the end of April. Although
short-term interest rates rose, yields on longer-term bonds declined.

In late March, the Federal Open Market Committee reported that pressures on
inflation had picked up in recent months and that pricing power had become more
evident. In early April, crude-oil prices briefly topped $58 per barrel. Later
that month, data on real gross domestic product suggested that the pace of
economic growth had slowed somewhat in the first quarter of 2005.

At MainStay, we recognize your concern about market volatility and we're pleased
to offer Funds appropriate for a wide variety of investment needs. At the end of
March 2005, MainStay introduced four new Asset Allocation Funds to broaden the
array of choices we provide investors. Each Asset Allocation Fund invests in
several other MainStay Funds and is subject to specific allocation targets and
constraints outlined in the prospectus.

Each MainStay Fund seeks to achieve its investment objective through consistent
application of an established investment approach that is consistently applied
over time. Although economic, industry, and geopolitical variables are
constantly in flux, we use careful research and consistent investment
disciplines as we seek to provide competitive performance for our shareholders
over full market cycles.

The reports that follow provide more detailed information about the specific
market forces and portfolio management decisions that affected your MainStay
Fund investments during the six months ended April 30, 2005.

Sincerely,


/s/ CHRISTOPHER O. BLUNT


Christopher O. Blunt

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 change in share price, reinvestment of dividend and capital-gain
distributions, and maximum applicable sales charges explained in this paragraph.
The graphs assume an initial investment of $10,000 and reflect the deduction of
all sales charges that would have applied for the period of investment. Class A
shares are sold with a maximum initial sales charge of 5.5% and an annual 12b-1
fee of .25%. Class B shares are sold with no initial sales charge, are subject
to a contingent deferred sales charge (CDSC) of up to 5% 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% 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
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. The fee waivers and/or expense limitations are voluntary and
may be discontinued at any time. From inception (1/2/91) through 12/31/03,
performance for Class A, B, and C shares (each first offered 1/2/04) includes
the historical performance of Class I shares adjusted to reflect the applicable
sales charge (or CDSC) and fees and expenses for Class A, B, and C shares.

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY ALL CAP GROWTH FUND

The example below is intended to describe the fees and expenses borne by
shareholders during the reporting period 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, if applicable, exchange fees, and sales
charges (loads) on purchase payments, and (2) ongoing costs, including
management fees, distribution and/or service (12b-1) fees, and other Fund
expenses. 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 November 1, 2004, to April 30, 2005.

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 over the period. 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 balance or
expenses you paid for the period. You may use this information to compare the
ongoing costs of investing in the Fund and 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 Rudolph C. Carryl and Edmund C. Spelman
of MacKay Shields LLC

CAN YOU BRIEFLY DESCRIBE THE FUND'S INVESTMENT APPROACH?

The Fund normally invests in securities that have growth characteristics and
that span the entire range of market capitalizations as described by the Russell
3000(R) Growth Index.(1) The Fund normally invests at least 80% of its assets in
equity securities. In implementing this strategy, the Fund normally invests in
securities of companies with investment characteristics such as: participation
in expanding product or service markets, increasing unit sales volume, growth in
revenues and earnings per share superior to that of the average of common stocks
comprising indices such as the S&P 500(R) Index,(2) and increasing return on
investment. The Fund maintains a flexible approach and may invest in various
types of companies and securities. We look for companies and securities
that we feel are ready for a rise in price or may experience acceleration in
growth of earnings, possibly as a result of changes in management, products,
consumer demand, or the economy. We may sell a security if we no longer believe
it will contribute to meeting the Fund's investment objective.

WHAT KEY FACTORS INFLUENCED THE EQUITY MARKET DURING THE REPORTING PERIOD?

The equity market was volatile during the six months ended April 30, 2005. The
reporting period began with the reelection of George W. Bush and a strong market
rally through the end of 2004. In the first few months of 2005, however,
continued interest-rate hikes by the Federal Reserve, rising inflationary
concerns, and record oil and gas prices caused the stock market to decline.

WHAT DECISIONS HAD THE BIGGEST INFLUENCE ON THE FUND'S PERFORMANCE?

Excluding all sales charges, the Fund outperformed its benchmark, the Russell
3000(R) Growth Index, during the reporting period. This resulted largely from
strength in the Fund's holdings in the energy, financials, health care, and
materials sectors. Performance was strong among companies in oil services,
health care services, coal, and diversified financial services.

WHICH INDIVIDUAL SECURITIES HAD THE GREATEST POSITIVE IMPACT ON PERFORMANCE
DURING THE REPORTING PERIOD?

The top-five contributors to the Fund's overall performance were WellPoint
(+56%),(3) PacifiCare Health Systems (+68%), United Healthcare (+31%), Peabody
Energy (+38%), and CareMark Rx (+34%). WellPoint, PacifiCare Health Systems, and
United Healthcare are all HMOs. WellPoint delivered strong earnings growth after
it merged with Anthem Health. Each of these HMOs benefited from solid enrollment
and medical-cost containment, which led to positive earnings revisions and
strong stock-price performance. Peabody Energy, a coal production company,
benefited from rising coal prices that resulted from strong demand. Caremark Rx,
a prescription-drug benefit management company, saw its shares rise on greater
generic-drug substitution, strong specialty distribution growth, and increasing
mail-order growth. The company delivered solid earnings-per-share growth and has
consistently guided analysts' expectations higher.

WHICH STOCKS DETRACTED FROM PERFORMANCE?

Symantec (-34%), an antivirus-software provider, saw its shares fall sharply
when the company announced the acquisition of Veritas Software, a
storage-software company. Investors believed the acquisition would slow
Symantec's growth rate. Internet-auction service company eBay (-33%) felt the
effects of a deep recession in Germany and other European countries, as well as
decelerating growth in U.S. transactions. This caused eBay to lower its earnings
guidance, and the stock declined sharply. Harman International (-36%), a
manufacturer of audio and video products serving the consumer and professional
markets, declined because of increased competition and a slowdown in worldwide
auto sales. The automotive industry is the key market for Harman's audio
products. Shares of motorcycle manufacturer Harley-Davidson (-18%) fell as the
company cut its motorcycle production because of increased inventory at its

lowered. Boston Scientific (-16%), a manufacturer of medical instruments, is
experiencing tremendous growth because of its leading drug-coated stent. This


Mid-capitalization companies are generally less established and their stocks may
be more volatile and less liquid than the securities of larger companies. Stocks
of small companies may be subject to greater price volatility, significantly
lower trading volumes, and greater spreads between bid and ask prices than
stocks of larger companies. Small companies may be more vulnerable to adverse
business or market developments than mid- or large-capitalization companies.

growth, however, is expected to slow dramatically, and investors are uncertain
about the company's sustainable growth rate going forward.

WERE THERE ANY SIGNIFICANT PURCHASES DURING THE REPORTING PERIOD?

The Fund purchased D.R. Horton (+18%), one of the largest homebuilders in the
United States. The company is benefiting from low interest rates and the
"ownership society" mentality of U.S. citizens. In addition, D.R. Horton's order
rates and backlogs are at an all-time high. The Fund added St. Joe (+34%), a
real estate operator, whose vast land holdings allow it to build popular
large-scale, mixed-use communities on prime property. We added medical-care
provider Aetna (+26%) to the Fund. The company has restructured its operations
and is delivering strong earnings growth while containing medical costs. Shares
of biotech company Genentech (+53%) were purchased for the Fund and have seen
dramatic share price appreciation, largely because of the company's strong drug
pipeline and its blockbuster cancer drug, Avastin, which continued to show
positive results in treating several types of cancer.

WHAT WERE SOME EXAMPLES OF SECURITIES THAT YOU SOLD DURING THE REPORTING PERIOD?

Puerto Rican financial services company Doral Financial (+7%) was sold after the
company disclosed that rising interest rates had forced it to lower its
assumptions for loan securitizations. Experience has taught us the propriety of
selling after such disclosure, and we sold the Fund's position before it
subsequently dropped more than 65%. We sold the Fund's position in Avaya (-13%),
a supplier of telecommunications equipment, after competition and reduced
customer spending caused sales to slow. The sale proved beneficial, since the
company's stock later fell 40% from our average sale price. Electronic Arts
(+29%) was sold as competition intensified in the entertainment software
industry. XBox, Playstation, and GameCube are planning to introduce new game
players for the 2006 season, and Electronic Arts has seen its growth slow
dramatically. The Fund's position in data processing and electronic commerce
solution provider First Data (+1%) was reduced, then eliminated, after the
company reported a decline in its core payment-services business.

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

The Fund's exposure to the consumer discretionary sector rose from 26.9% of net
assets at the beginning of the reporting period to 29.9% at the end, with no
impact on performance. The Fund's weighting in the energy sector rose from 7.6%
to 10.7% over the period, which benefited results. An increase from 18.2% to
21.1% in the health care sector also enhanced results. The Fund's exposure to
the industrials sector fell from 17% of net assets at the beginning of the
reporting period to 14.5% at the end of April, which had a positive impact
because the industrials sector underperformed the market as a whole. We also
decreased the Fund's weighting in information technology, moving from a 17.7%
weighting to 12.5%. The shift had a positive impact on performance.

WHAT IS YOUR OUTLOOK FOR THE MARKETS AND THE FUND?

We continue to focus on companies that can deliver above-average sales and
earnings growth on a consistent basis. We believe that over the long term, these
companies offer the best opportunities for outperforming the market. At the same
time, however, we are mindful of valuation and will not overpay for a stock if
it does not offer the potential for double-digit returns.

Although we are primarily bottom-up managers, selecting stocks on their
individual merits, we continue to monitor the economy, geopolitical events, and
other factors that may affect stock prices. As we look ahead, we continue to
favor consumer, industrial, energy, and health care service companies because
they appear to offer attractive risk-reward profiles.

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 change in share price, reinvestment of dividend and capital-gain
distributions, and maximum applicable sales charges explained in this paragraph.
The graphs assume an initial investment of $10,000 and reflect the deduction of
all sales charges that would have applied for the period of investment. Class A
shares are sold with a maximum initial sales charge of 5.5% and an annual 12b-1
fee of .25%. Class B shares are sold with no initial sales charge, are subject
to a contingent deferred sales charge (CDSC) of up to 5% 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% 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
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. The fee waivers and/or expense limitations are voluntary and
may be discontinued at any time. From inception (1/2/91) through 12/31/03,
performance for Class A, B, and C shares (each first offered 1/2/04) includes
the historical performance of Class I shares adjusted to reflect the applicable
sales charge (or CDSC) and fees and expenses for Class A, B, and C shares.

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY ALL CAP VALUE FUND

The example below is intended to describe the fees and expenses borne by
shareholders during the reporting period 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, if applicable, exchange fees, and sales
charges (loads) on purchase payments, and (2) ongoing costs, including
management fees, distribution and/or service (12b-1) fees, and other Fund
expenses. 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 November 1, 2004, to April 30, 2005.

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

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 over the period. 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 balance or
expenses you paid for the period. You may use this information to compare the
ongoing costs of investing in the Fund and 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 Richard A. Rosen and Mark T. Spellman
of MacKay Shields LLC

CAN YOU BRIEFLY DESCRIBE THE FUND'S INVESTMENT APPROACH?

The Fund normally invests in securities that have value characteristics and that
span the entire range of market capitalizations reflected in the Russell 3000(R)
Value Index.(1) The Fund normally invests at least 80% of its assets in equity
securities. In implementing this strategy, the Fund principally invests in
common stocks that we believe are selling below their value when purchased, that
typically pay dividends, and that are listed on a national securities exchange
or are traded in the over-the-counter market. When assessing whether a stock is
undervalued, we compare the stock's market price to the company's cash flow and
interest-coverage ratios, the company's book value, the estimated value of the
company's assets, and the company's growth rates and future earnings potential.
There may be non-dividend- paying stocks in the portfolio if they meet the
"undervalued" criteria. We may sell securities that we believe no longer
contribute to the Fund's ability to meet its investment objective.

WHAT MAJOR FACTORS INFLUENCED THE STOCK MARKET DURING THE SIX MONTHS ENDED APRIL
30, 2005?

Stocks moved somewhat higher during the six-month period, although performance
varied widely across capitalization levels and investment styles. Mid-cap and
large-cap value stocks led the equity market, outpacing growth stocks of all
capitalization levels by a significant margin. Specific industries were subject
to volatile undercurrents during the reporting period. Energy stocks dominated
the market as crude-oil prices topped $58 per barrel before backing off their
record levels by the end of April. A pick-up in merger-and-acquisition activity
in the energy sector also helped drive share prices higher. Information
technology stocks were generally weaker, as incremental data showed slowing
trends in revenue and order growth and mediocre progress in earnings growth.
Meanwhile, the Federal Open Market Committee continued to raise the targeted
federal funds rate, and the Federal Reserve intensified its rhetoric about
inflation concerns.

WHAT WERE SOME OF THE FUND'S STRONG PERFORMERS DURING THE REPORTING PERIOD?

High crude-oil prices benefited the shares of several of the Fund's energy
sector holdings, particularly offshore drillers Transocean Energy (+32%)(2) and
Pride International (+21%). A number of names in the health care sector also
performed well. Positive surprises from hospital operators HCA (+53%) and
Universal Health Services (+37%) drove their share prices up, as each reported
better-than-expected first-quarter 2005 trends and results.

Soft-drink and confectionery company Cadbury Schweppes (+23%) rose during the
reporting period. Cadbury Schweppes posted steadily improving results, driven by
positive trends in the company's brands and by successful integration of recent
acquisitions.

HOW DID THE FUND'S INFORMATION TECHNOLOGY STOCKS FARE DURING THE SIX MONTHS
ENDED APRIL 30, 2005?

Several names in the information technology sector detracted from the Fund's
performance. Shares of mainframe-software maker BMC Software (-14%) slid on
disappointing earnings results. The Fund continued to hold this stock, however,
since we found its longer-term prospects compelling despite softer-than-
anticipated short-term trends. IBM (-15%) suffered from sluggish revenue and
weak new-business-signing trends early in 2005. IBM subsequently announced a
major restructuring plan to cut costs in the affected areas, and we were
encouraged by the company's quick and decisive action.

WERE THERE OTHER STOCKS THAT DETRACTED FROM THE FUND'S RESULTS?

Small-cap industrial concern Insituform Technologies (-25%) saw its share price
drop after reporting weaker-than-expected results. Since we believed that the
market had overreacted, the Fund continued to hold the shares.
Graphite-electrode manufacturer GrafTech International (-59%) also suffered from
weaker-than-expected results. After meeting with senior management to review the
company's recent results and strategy for the future, however, we

Mid-capitalization companies are generally less established and their stocks may
be more volatile and less liquid than the securities of larger companies. Stocks
of small companies may be subject to greater price volatility, significantly
lower trading volumes, and greater spreads between bid and ask prices than
stocks of larger companies. Small companies may be more vulnerable to adverse
business or market developments than mid- or large-capitalization companies.

added to the Fund's position in the stock. Mortgage and specialty insurer PMI
Group (-9%) also detracted from Fund performance for the period. We continued to
hold the PMI shares on the belief that macroeconomic trends, improving credit
quality, and increased market share in municipal-bond insurance may help the
stock in the months ahead.

HOW WAS THE FUND POSITIONED AT THE END OF THE REPORTING PERIOD?

At the end of April 2005, the Fund had overweighted positions relative to the
Russell 3000(R) Value Index in consumer staples, energy, health care,
information technology, and telecommunication services. As of the same date, the
Fund was underweighted relative to the Index in utilities, consumer
discretionary, financials, materials, and industrials.

WHAT DO YOU ANTICIPATE GOING FORWARD?

We believe that higher interest rates and slower gross-domestic-product growth
may be important factors in the equity market over the near term.
Larger-capitalization names still seem to be offering more value than
smaller-capitalization names, and this is reflected in many of the Fund's
holdings in the health care and consumer staples sectors.

We also expect high energy prices to continue to affect the overall stock market
as manufacturers struggle to contain energy costs or pass them along to their
consumers. Many of the Fund's energy holdings have approached our price targets,
and we have recently been selling shares. The Fund continues to overweight the
energy sector relative to the Russell 3000(R) Value Index but to a lesser degree
than at the start of the reporting period.

After a strong multiyear run in economic-recovery plays in the industrials and
materials sectors, we have pared back or sold many of the Fund's positions. We
intend to keep the Fund under-weighted in these two sectors for the near term.

Information technology stocks have disappointed to date in 2005, but we continue
to find reasonable value in this sector and intend to remain over-weighted. We
have yet to find much value in the utilities sector, in larger banks, or in real
estate investment trusts (REITs), and we intend to keep the Fund underweighted
in these areas.

We remain confident in our disciplined classic value strategy and will continue
to seek opportunities among undervalued stocks with improving fundamental
characteristics.

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 change in share price, reinvestment of dividend and capital-gain
distributions, and maximum applicable sales charges explained in this paragraph.
The graphs assume an initial investment of $10,000 and reflect the deduction of
all sales charges that would have applied for the period of investment. Class A
shares are sold with a maximum initial sales charge of 5.5% and an annual 12b-1
fee of .25%. Class B shares are sold with no initial sales charge, are subject
to a contingent deferred sales charge (CDSC) of up to 5% 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% 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
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. The fee waivers and/or expense limitations are voluntary and
may be discontinued at any time. From inception (12/27/94) through 12/31/03,
performance for Class A and B shares (each first offered 1/2/04) includes the
historical performance of Class I shares adjusted to reflect the applicable
sales charge (or CDSC) and fees and expenses for Class A and

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY MID CAP OPPORTUNITY FUND

The example below is intended to describe the fees and expenses borne by
shareholders during the reporting period 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, if applicable, exchange fees, and sales
charges (loads) on purchase payments, and (2) ongoing costs, including
management fees, distribution and/or service (12b-1) fees, and other Fund
expenses. 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 November 1, 2004, to April 30, 2005.

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 over the period. 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 balance or
expenses you paid for the period. You may use this information to compare the
ongoing costs of investing in the Fund and 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 Kathy A. O'Connor and Jeffrey Sanders
of New York Life Investment Management LLC

CAN YOU BRIEFLY DESCRIBE THE FUND'S INVESTMENT APPROACH?

The Fund normally invests at least 80% of its assets in common and preferred
stock of companies with market capitalizations that, at the time of investment,
are similar to those of companies in the Russell Midcap(R) Index,(1) the
Standard & Poor's MidCap 400(R) Index,(2) or a universe selected from the
smallest 800 companies of the largest 1,000 companies ranked by market
capitalization. In implementing this strategy, the Fund invests primarily in
stocks of mid-capitalization companies that we determine to have strong or
improving operating characteristics and to be relatively overlooked or
undervalued by the market. The Fund uses a quantitative and statistical model to
analyze the relative quality and value of stocks.

WHAT MAJOR FACTORS INFLUENCED THE STOCK MARKET DURING THE SIX MONTHS ENDED APRIL
30, 2005?

During the six months ended April 30, 2005, most broadly watched equity indices
saw positive performance, but certain small-cap core and small-cap growth
indices declined. Mid-capitalization stocks showed the strongest overall
performance, followed by large- and then small-capitalization stocks. The
market's general preference for value equities over growth stocks was clearly
evident among mid-capitalization issues. During the reporting period, the
domestic equity market was influenced by crude-oil price fluctuations,
job-growth concerns, the decline of the U.S. dollar, and continuing instability
in the Middle East.

HOW DID THE FUND PERFORM IN THIS MARKET ENVIRONMENT?

All share classes of MainStay Mid Cap Opportunity Fund underperformed the
Russell Midcap(R) Value Index(3) for the period ended April 30, 2005. In the
banks and technology hardware & equipment industry groups, the Fund's holdings
underperformed peer stocks in the Index. The utilities industry group had strong
performance for the six-month reporting period, but the Fund's underweighted
position relative to the Russell Midcap(R) Value Index detracted from the Fund's
relative performance.

The Russell Midcap(R) Value Index is a capitalization-weighted index, which
means that it has larger weightings among securities with larger market
capitalizations. MainStay Mid Cap Opportunity Fund attempts to have equal
weights among the securities in its portfolio.

For the six months ended April 30, 2005, the Russell Midcap(R) Value Index was
approximately 50% weighted in the top 25% of Index companies (from largest
market capitalization to smallest). This significantly contributed to the return
of the Russell Midcap(R) Value Index. On the other hand, MainStay Mid Cap
Opportunity Fund was weighted only 42% in the top 25% of Index companies with
rank determined by market capitalization. This underweighted position and lower
overall exposure to the top 25% of companies relative to the Russell Midcap(R)
Value Index held back the relative performance of the Fund.

It is important to note that the Fund was invested in some, but not all of the
companies in the Russell Midcap(R) Value Index.

WHICH INDUSTRY GROUPS AND INDIVIDUAL STOCKS PROVIDED THE STRONGEST PERFORMANCE
FOR THE FUND DURING THE SIX-MONTH REPORTING PERIOD?

The five strongest-performing industry groups were energy; food, beverage &
tobacco; utilities; health care equipment & services; and retailing. Among the
strongest contributors to the Fund's performance were petroleum refiner Premcor
(+59.9%),(4) entertainment-software company Activision (+35.2%), health benefits
provider Humana (+69.1%), steel manufacturer Nucor (+20.5%), and transportation
and health care services provider Laidlaw International (+31.4%).

Mid-capitalization companies are generally less established and their stocks may
be more volatile and less liquid than the securities of larger companies.
Foreign securities may be subject to greater risks than U.S. investments,
including currency fluctuations, less-liquid trading markets, greater price
volatility, political and economic instability, less publicly available
information, and changes in tax or currency laws or monetary policy.
1. See footnote on page 33 for more information on the Russell Midcap(R) Index.
2. The S&P MidCap 400(R) Index is an unmanaged market-value weighted index that
   consists of 400 domestic common stocks chosen for market size, liquidity, and
   industry-group representation and is generally considered representative of
   the market for domestic mid-cap stocks. Results assume reinvestment of all
   income and capital gains. An investment cannot be made directly into an
   index.
3. See footnote on page 33 for more information on the Russell Midcap(R) Value
   Index.
4. Percentages reflect total returns of Fund holdings in the securities
   mentioned, including purchases and sales, for the six months ended April 30,
   2005, or for the portion of the reporting period such securities were held in
   the Fund, if shorter. Securities are mentioned in the order of their
   contribution to Fund performance, which takes total returns and weightings
   both into account.

 36   MainStay Mid Cap Opportunity Fund


WHICH INDUSTRY GROUPS AND INDIVIDUAL STOCKS DETRACTED FROM THE FUND'S
PERFORMANCE?

The Fund's five weakest-performing industry groups during the six-month
reporting period were banks, technology hardware & equipment, capital goods,
automobiles & components, and telecommunication services. The greatest negative
contribution to the Fund's performance came from R&G Financial (-62.1%), a
Puerto Rico bank holding company. The second-greatest negative contributor was
telecommunications equipment company UTStarcom (-26.5%), followed by Nuveen
Investments (-11.9%), smokeless tobacco and wine & spirits holding company UST
(-12.3%), and steel manufacturer Steel Dynamics (-27.4%).

WERE THERE ANY SIGNIFICANT EQUITY PURCHASES OR SALES DURING THE REPORTING
PERIOD?

The Fund uses its proprietary model to select stocks that have relatively
improving operating characteristics and are relatively undervalued. One of the
stocks the Fund purchased during the reporting period was Toys "R" Us (+27.0%),
a worldwide retailer of toys, apparel, and other children's products. The Fund
purchased the stock in November 2004 and April 2005. We established a position
in Apache (+9.9%), an energy company, in November 2004 and added to the position
throughout the reporting period. The Fund also established a position in
independent oil and gas exploration and production company Anadarko Petroleum
(+8.4%) in November 2004 and added to the position in April 2005. All three of
these companies exhibited improving fundamentals and, according to our
proprietary model, were relatively undervalued at the time of purchase.

The Fund sells stocks that exhibit deteriorating operating results, are
relatively overvalued, or both. In December 2004, the Fund sold its position in
Saks (+17.8%), when the retailer decided to close some of its stores as part of
a reorganization. The Fund sold its entire position in Outback Steakhouse
(+17.4%) in February 2005 when our quantitative model showed that the stock had
become overvalued. Homebuilder Toll Brothers (+17.1%) was sold for a similar
reason in December 2004.

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

Weighting changes in the Fund result from a combination of security performance,
industry performance, and the Fund's proprietary security selection process.
During the reporting period, the Fund's weighting in the banks industry group
increased from 12.2% of net assets at the end of October 2004 to 14.9% at the
end of April 2005. Another significant change was in the consumer durables &
apparel industry group, where the Fund's weighting declined from 9.1% at the
beginning of the reporting period to 5.5% on April 30, 2005.

HOW DID THE FUND'S WEIGHTINGS COMPARE WITH THOSE OF THE RUSSELL MIDCAP(R) VALUE
INDEX AT THE END OF THE REPORTING PERIOD?

As of April 30, 2005, the Fund was overweighted relative to the Russell
Midcap(R) Value Index in the banks industry group as well as in food, beverage &
tobacco; household & personal products; and energy. During the reporting period,
the Fund's performance benefited from relatively overweighted positions in
energy; food, beverage & tobacco; and household & personal products.

WHAT IS YOUR OUTLOOK FOR THE FUTURE?

As always, the Fund will continue to focus on stocks that our proprietary model
indicates have relatively improving operating characteristics and are relatively
undervalued.

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 change in share price, reinvestment of dividend and capital-gain
distributions, and maximum applicable sales charges explained in this paragraph.
The graphs assume an initial investment of $10,000 and reflect the deduction of
all sales charges that would have applied for the period of investment. Class A
shares are sold with a maximum initial sales charge of 3% and an annual 12b-1
fee of .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 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. The Manager has contractually agreed to limit the
Fund's total fund operating expenses through December 31, 2005. There is no
guarantee that the contractual waiver will continue after that date. From
inception (1/2/91) through 12/31/03, performance for Class A shares (first
offered 1/2/04) includes the historical performance of Class I shares adjusted
to reflect the applicable sales charge and fees and expenses for Class A shares.

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY S&P 500 INDEX FUND

The example below is intended to describe the fees and expenses borne by
shareholders during the reporting period 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, if applicable, exchange fees, and sales
charges (loads) on purchase payments, and (2) ongoing costs, including
management fees, distribution and/or service (12b-1) fees, and other Fund
expenses. 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 November 1, 2004, to April 30, 2005.

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 over the period. 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 balance or
expenses you paid for the period. You may use this information to compare the
ongoing costs of investing in the Fund and 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 manager Francis J. Ok of New York Life
Investment Management LLC

CAN YOU BRIEFLY DESCRIBE THE FUND'S INVESTMENT APPROACH?

The Fund normally invests at least 80% of its total assets in stocks contained
in the S&P 500(R) Index(1) in the same proportion, to the extent feasible, as
they are represented in the Index. In implementing this strategy, we use
statistical techniques to determine which stocks are to be purchased or sold to
replicate the S&P 500(R) Index to the extent feasible. From time to time,
adjustments may be made in the Fund's portfolio because of changes in the
composition of the Index.

WHAT WERE THE MAJOR FACTORS THAT AFFECTED THE STOCK MARKET DURING THE SIX MONTHS
ENDED APRIL 30, 2005?

For much of the six-month reporting period, U.S. equity-market sentiment was
subdued, as factors such as crude-oil price fluctuations, job-growth concerns,
the declining value of the U.S. dollar versus other major currencies, and
instability in the Middle East continued to affect the U.S. economy. During the
reporting period, the Federal Open Market Committee raised the federal funds
target rate by 25 basis points four times--in November and December 2004 and in
February and March 2005. (A basis point is 1/100th of one percentage point.)
These four rate hikes brought the targeted federal funds rate from 1.75% at the
beginning of the reporting period to 2.75% at the end of April. The Federal
Reserve remains optimistic that the economy is well on its way to recovery after
the 2001 recession. Although it appears that longer-term inflation expectations
remain well contained, the Federal Reserve is now focused on trying to ease
inflation.

Broadly watched equity indices ended the six-month reporting period with mixed
results. Mid-capitalization stocks performed best, followed by large-
capitalization and then small-capitalization stocks. The market clearly favored
value equities over growth stocks for large- and mid-cap issues, although
different data sources suggested different style preferences among small-cap
issues.(2)

WHAT WERE THE BEST-PERFORMING INDUSTRY GROUPS(3) IN THE S&P 500(R) INDEX DURING
THE REPORTING PERIOD?

From a total-return perspective, health care equipment & services (+18.40%)(4)
was the best-performing industry group for the six months ended April 30, 2005.
Other top-performing industry groups included utilities (+16.32%), energy
(+15.88%), food, beverage & tobacco (+12.99%), and household & personal products
(+10.35%).

Some of the industry groups with the highest total returns were among the
strongest contributors to the performance of the Index. Other industry groups,
however, had strong impact on Index performance because of higher weightings,
despite lower total returns. On the basis of impact, which takes weightings and
total returns both into account, the leading industry group was energy
(+15.88%), followed by health care equipment & services (+18.40%), food,
beverage & tobacco (+12.99%), capital goods (+5.85%), and pharmaceuticals &
biotechnology (+6.34%).

WHICH INDUSTRY GROUPS WERE THE WORST PERFORMERS?

On the basis of total returns alone, the worst-performing industry groups in the
Index for the six-month reporting period were automobiles & components
(-23.89%), technology hardware & equipment (-6.86%), retailing (-6.85%),
transportation (-4.91%), and food & staples retailing (-4.64%).

For the six months ended April 30, 2005, technology hardware & equipment
(-6.86%) was the industry group with the greatest negative impact on Index
performance when weightings and total returns were

Index funds generally seek to reflect the performance of an index or an
allocation among indices, unlike other funds, whose objectives may, in some
cases, involve seeking to outperform an index or other benchmark. The Fund may
invest in derivatives, which may increase the volatility of the Fund's net asset
value and may result in a loss to the Fund.
1. See footnote on page 47 for more information on the S&P 500(R) Index.
2. Specifically, for the six months ended April 30, 2005, the Russell 2000(R)
   Growth Index underperformed the Russell 2000(R) Value Index, while the S&P
   SmallCap 600/Barra Growth Index outperformed the S&P SmallCap 600/Barra Value
   Index. Each of these indices is unmanaged, contains different issues, and is
   considered to be generally representative of small-cap growth or small-cap
   value stocks, as the index name suggests. An investment cannot be made
   directly into an index.
3. The Global Industry Classification Standard categorizes companies by sector,
   industry group, industry, and subindustry. Results in this section of the
   semiannual report reflect industry group and company performance. In the
   Portfolio of Investments that follows, companies are listed by industry.
4. Percentages reflect the total-return performance, including reinvestment of
   all dividends and capital gains, of the industry groups or the securities
   mentioned for the six months ended 4/30/05. Purchases and sales within the
   Fund's portfolio may cause the performance of Fund holdings to differ from
   that of the industry groups or securities themselves.

components (-23.89%), food & staples retailing (-4.64%), and media (-1.16%).

WHICH INDIVIDUAL STOCKS HAD THE HIGHEST TOTAL RETURNS DURING THE REPORTING
PERIOD?

For the six months ended April 30, 2005, the S&P 500(R) Index company with the
best total return was Humana (+80.94%). Valero Energy (+60.00%) had the
second-best total return, followed by WellPoint (+58.89%), Aetna (+54.52%), and
HCA (+52.89%).

As impressive as these returns may be, the five stocks that made the greatest
positive contribution to the performance of the S&P 500(R) Index all had higher
weightings and lower total returns. On the basis of impact, which takes
weightings and total returns both into account, the strongest positive
contributor to the performance of the Index for the six-month reporting period
was ExxonMobil (+17.07%), followed by Altria Group (+37.24%), Johnson & Johnson
(+18.61%), General Electric (+7.39%), and Citigroup (+7.80%).

WHICH STOCKS WERE THE WEAKEST PERFORMERS DURING THE REPORTING PERIOD?

For the six months ended April 30, 2005, the S&P 500(R) Index stock with the
worst total return was Delphi (-60.17%). Other particularly weak performers
included JDS Uniphase (-53.31%), Sanmina-SCI (-50.00%), Maytag (-43.15%), and
Gateway (-41.71%).

On the basis of impact, which takes weightings and total returns both into
account, Wal-Mart Stores (-12.10%) made the greatest negative contribution to
the performance of the Index for the six-month reporting period. American
International Group (-15.98%) was next, followed by eBay (-35.04%),
International Business Machines (-14.57%), and Fannie Mae (-22.40%).

WERE ANY CHANGES MADE TO THE FUND OR TO THE INDEX DURING THE REPORTING PERIOD?

The Fund seeks to track the performance and weightings of stocks in the S&P
500(R) Index. The Index itself, however, may change from time to time as
companies merge, divest units, add to their market capitalization, or face
financial difficulties. Standard & Poor's may also occasionally adjust the Index
to better reflect the companies that it believes are most representative of the
makeup of the U.S. economy. During the six months ended April 30, 2005, nine
companies were added to the S&P 500(R) Index and nine companies were deleted
from it.

Among the additions were such well-known companies as Archstone-Smith Trust, L-3
Communications Holdings, News Corp., and XTO Energy. Among the deletions were
familiar names such as Deluxe, PeopleSoft, WellPoint Health Networks,
Winn-Dixie, and Worthington Industries. Sears, Roebuck merged with Kmart and was
deleted from the Index but simultaneously reappeared as Sears Holdings. Adolf
Coors merged with Molson and was deleted when Molson Coors Brewing was added to
the Index.

WHAT DO YOU ANTICIPATE GOING FORWARD?

As always, the markets will continue to be buffeted by shifting economic,
monetary, and geopolitical variables. Because we are index investors, however,
we do not attempt to predict how specific forces will affect the stock market.
Instead, we seek to track the performance of the S&P 500(R) Index wherever the
markets may move.

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 change in share price, reinvestment of dividend and capital-gain
distributions, and maximum applicable sales charges explained in this paragraph.
The graphs assume an initial investment of $10,000 and reflect the deduction of
all sales charges that would have applied for the period of investment. Class A
shares are sold with a maximum initial sales charge of 5.5% and an annual 12b-1
fee of .25%. Class B shares are sold with no initial sales charge, are subject
to a contingent deferred sales charge (CDSC) of up to 5% 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% 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
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. The fee waivers and/or expense limitations are voluntary and
may be discontinued at any time. From inception (1/12/87) through 12/31/03,
performance for Class A and B shares (each first offered 1/2/04) includes the
historical performance of Class I shares adjusted to reflect the applicable
sales charge (or CDSC) and fees and expenses for Class A and B shares. Prior to
1/2/04, the Fund offered Class L shares, which were subject to a 1% sales charge
and a 1% CDSC on redemptions within one year of purchase. From inception through
12/29/02, performance for Class L shares (first offered 12/30/02) includes the
historical performance of Class I shares adjusted to reflect the applicable
sales charge (or CDSC) and fees and expenses for Class L shares. Effective
1/02/04, all outstanding Class L shares of the Fund were converted to Class C
shares, redesignated Class C shares, or both.

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY SMALL CAP OPPORTUNITY FUND

The example below is intended to describe the fees and expenses borne by
shareholders during the reporting period 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, if applicable, exchange fees, and sales
charges (loads) on purchase payments, and (2) ongoing costs, including
management fees, distribution and/or service (12b-1) fees, and other Fund
expenses. 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 November 1, 2004, to April 30, 2005.

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 over the period. 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 balance or
expenses you paid for the period. You may use this information to compare the
ongoing costs of investing in the Fund and 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 Kathy A. O'Connor and Jeffrey Sanders
of New York Life Investment Management LLC

CAN YOU BRIEFLY DESCRIBE THE FUND'S INVESTMENT APPROACH?

The Fund normally invests at least 80% of its assets in common and preferred
stock of companies with market capitalizations that, at the time of investment,
are similar to those of companies in the Russell 2000(R) Index, the S&P SmallCap
600(R) Index, or a universe selected from the smallest 2,000 companies of the
largest 3,000 companies, ranked by market capitalization.(1) In implementing
this strategy, the Fund focuses primarily on small-capitalization stocks that
have strong or improving operating characteristics and have been overlooked by
the market. The Fund uses a quantitative and statistical model to analyze the
relative quality and value of stocks.

WHAT MAJOR FACTORS INFLUENCED THE STOCK MARKET DURING THE SIX MONTHS ENDED APRIL
30, 2005?

During the six months ended April 30, 2005, most broadly watched equity indices
saw positive performance, but certain small-cap core and small-cap growth
indices declined. Mid-cap stocks performed relatively better than their large-
and small-cap counterparts. The market clearly favored value equities over
growth stocks for large- and mid-cap issues, although different data sources
suggested different style preferences among small-cap issues.(2) Throughout much
of the reporting period, the domestic equity market was influenced by crude-oil
price fluctuations, job-growth concerns, the decline of the U.S. dollar, and
continuing instability in the Middle East.

HOW DID THE FUND PERFORM IN THIS MARKET ENVIRONMENT?

MainStay Small Cap Opportunity Fund outperformed the Russell 2000(R) Value
Index(3) for the six months ended April 30, 2005. The Fund's relative
performance in the energy, retailing, and insurance industry groups was stronger
than that of peer stocks in the Index. The Fund held overweighted positions
relative to the Index in the energy and insurance industry groups, so the Fund's
outperformance in these industry groups strengthened relative performance.

WHICH INDUSTRY GROUPS AND INDIVIDUAL STOCKS PROVIDED THE STRONGEST PERFORMANCE
FOR THE FUND DURING THE SIX-MONTH REPORTING PERIOD?

The five strongest-performing industry groups were energy, retailing, insurance,
materials, and commercial services & supplies. Among the strongest contributors
to the Fund's performance were steel manufacturer Oregon Steel Mills
(+60.6%),(4) Massachusetts-based automobile-insurance company Safety Insurance
Group (+38.1%), steel service center Olympic Steel (+44.4%), Wisconsin-based
retailer ShopKo Stores (+29.1%), and construction holding company Building
Materials Holding (+31.4%).

WHICH INDUSTRY GROUPS AND INDIVIDUAL STOCKS DETRACTED FROM THE FUND'S
PERFORMANCE?

The Fund's five weakest-performing industry groups during the six-month
reporting period were banks, automobiles & components, technology hardware &
equipment, transportation, and consumer services. The greatest negative
contribution to the Fund's performance came from Visteon (-53.0%), a worldwide
supplier of automotive systems, modules, and components. The second-greatest
negative contributor was cemetery company Steward Enterprises (-22.6%), followed
by insurance and financial services company UICI (-25.5%),
network-infrastructure-equipment company MRV Communications (-45.7%), and metal
distributor Ryerson Tull (-32.4%).

WERE THERE ANY SIGNIFICANT EQUITY PURCHASES OR SALES DURING THE REPORTING
PERIOD?

The Fund uses its proprietary model to select stocks that have relatively
improving operating characteristics and are relatively undervalued. One of the
stocks


Stocks of small-capitalization companies may be subject to greater price
volatility, significantly lower trading volumes, and greater spreads between bid
and ask prices than stocks of larger companies. Small companies may be more
vulnerable to adverse business or market developments than mid- or
large-capitalization companies. Foreign securities may be subject to greater
risks than U.S. investments, including currency fluctuations, less-liquid
trading markets, greater price volatility, political and economic instability,
less publicly available information, and changes in tax or currency laws or
monetary policy.
1. See footnote on page 67 for more information on the Russell 2000(R) Index and
   the S&P SmallCap 600(R) Index.
2. Specifically, for the six months ended April 30, 2005, the Russell 2000(R)
   Growth Index underperformed the Russell 2000(R) Value Index, while the S&P
   SmallCap 600/Barra Growth Index outperformed the S&P SmallCap 600/Barra Value
   Index. Each of these indices is unmanaged, contains different issues, and is
   considered to be generally representative of small-cap growth or small-cap
   value stocks, as the index name suggests. An investment cannot be made
   directly into an index.
3. See footnote on page 67 for more information on the Russell 2000(R) Value
   Index.
4. Percentages reflect total returns of Fund holdings in the securities
   mentioned, including purchases and sales, for the six months ended April 30,
   2005, or for the portion of the reporting period such securities were held in
   the Fund, if shorter. Securities are mentioned in the order of their
   contribution to Fund performance, which takes total returns and weightings
   both into account.

 70   MainStay Small Cap Opportunity Fund


the Fund purchased during the reporting period was Titanium Metals (+60.0%), a
producer of titanium melted and mill products, whose sales increased 29% in the
first quarter of 2005 compared to the first quarter of 2004. The Fund purchased
the stock in November 2004 and added to it in April 2005. We established a
position in Alliance Imaging (+31.9%), a diagnostic-imaging-services company, in
November 2004 and added to the position in April 2005. The Fund also established
a position in ShopKo Stores (+29.1%) from February through April 2005. The
company, which was one of the Fund's top performers, increased gross margins
through improved promotional planning and markdown management. All three of
these companies exhibited improving fundamentals and, according to our
proprietary model, were relatively undervalued at the time of purchase.

The Fund sells stocks that exhibit deteriorating operating results, are
relatively overvalued, or both. The Fund sold its entire position in Oregon
Steel Mills (+60.6%) in January and February 2005. The Fund sold tubular steel
products company NS Group (+54.4%) in January and February 2005 and eliminated
its position in Olympic Steel (+44.4%) in December 2004 and January 2005.
According to our proprietary quantitative model, all three of these stocks had
become overvalued.

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

Weighting changes in the Fund result from a combination of security performance,
industry performance, and the Fund's proprietary security selection process. The
Fund held 3.59% of its net assets in the utilities industry group on October 31,
2004. Over the course of the reporting period, this weighting increased to 8.76%
by April 30, 2005. The Fund's weighting in the energy industry group declined
from 18.56% at the beginning of the reporting period to 12.18% at the end of
April 2005.

HOW DID THE FUND'S WEIGHTINGS COMPARE WITH THOSE OF THE RUSSELL MIDCAP(R) VALUE
INDEX AT THE END OF THE REPORTING PERIOD?

As of April 30, 2005, the Fund was overweighted relative to the Russell 2000(R)
Value Index in the insurance, energy, and transportation industry groups. As
previously mentioned, the Fund benefited from its overweighted positions in the
insurance and energy industry groups. As of the same date, the Fund was
underweighted relative to the Russell 2000(R) Value Index in the utilities,
banks, and real estate industry groups. The underweighted position in banks
helped relative performance, because the industry group as a whole showed weak
results.

WHAT IS YOUR OUTLOOK FOR THE FUTURE?

As always, the Fund will continue to focus on stocks that our proprietary model
indicates have relatively improving operating characteristics and are relatively
undervalued.

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 change in share price and reinvestment of dividend and capital-gain
distributions. The graphs assume an initial investment of $10,000. Class I
shares are sold with no initial sales charge or CDSC, have no annual 12b-1 fees,
and are generally available to corporate and institutional investors with a
minimum initial investment of $5 million. Sweep Shares Class shares are sold
with no initial sales charge or CDSC, have an annual 12b-1 fee of .25%, and are
available only through financial institutions participating in a sweep account
arrangement. Performance figures reflect certain fee waivers and/or expense
limitations, without which total returns may have been lower. The fee waivers
and/or expense limitations are voluntary and may be discontinued at any time.
From inception (1/2/91) through 12/7/98, performance for the Sweep Shares Class
shares (first offered 12/8/98) includes the performance of Class I shares.

   7-day yield of 1.90% and a 7-day current yield of 1.88% for Sweep Shares
   Class shares. These yields reflect certain expense limitations. Had these
   expense limitations not been in effect, the effective 7-day yield and the
   current 7-day yield would have been 1.98% and 1.96% for Class I shares and
   1.54% and 1.53% for Sweep Shares Class shares. These expense limitations are
   voluntary and may be terminated or revised at any time. The current yield is
   more reflective of the Fund's earnings than the total return.

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY CASH RESERVES FUND

The example below is intended to describe the fees and expenses borne by
shareholders during the reporting period 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, if applicable, exchange fees, and sales
charges (loads) on purchase payments, and (2) ongoing costs, including
management fees, distribution and/or service (12b-1) fees, and other Fund
expenses. 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 November 1, 2004, to April 30, 2005.

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 over the period. 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 balance or
expenses you paid for the period. You may use this information to compare the
ongoing costs of investing in the Fund and 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 Mark C. Boyce and David E. Clement,
CFA, of New York Life Investment Management LLC

CAN YOU BRIEFLY DESCRIBE THE FUND'S INVESTMENT APPROACH?

The Fund invests in high-quality, short-term securities that are denominated in
U.S. dollars and mature in 13 months or less. The Fund may invest in obligations
of the U.S. government and its agencies or instrumentalities. It may also invest
in CDs, bankers' acceptances, commercial paper, loans, time deposits, repurchase
agreements, and corporate debt securities. The Fund's investments may also
include variable rate notes, floaters, and asset-backed securities.

WHAT MAJOR FACTORS INFLUENCED THE MONEY MARKETS DURING THE SIX MONTHS ENDED
APRIL 30, 2005?

The most significant factor affecting the money markets was Federal Reserve
action to tighten the money supply. During the reporting period, the Federal
Open Market Committee increased the targeted federal funds rate four times--in
November and December 2004 and in February and March 2005--with a 25 basis point
move on each occasion. This brought the targeted federal funds rate to 2.75% at
the end of the six-month reporting period. The financial markets anticipate that
the Federal Open Market Committee will continue to tighten interest rates for
the foreseeable future.

DID YOU ADJUST THE FUND'S DURATION POSITIONING IN RESPONSE TO THE FEDERAL OPEN
MARKET COMMITTEE'S RATE HIKES?

During the six-month reporting period, the Fund's duration was managed in the
range of 45 to 65 days. At the end of the reporting period, the Fund had a
duration of 62 days. This strategy allowed the Fund to react more quickly to
interest rate changes as we sought to benefit from rising interest rates. Going
forward, we believe that this strategy may continue to have a positive impact on
the Fund's performance because it is widely anticipated that interest rates will
continue to rise.

DID THE STEEPENING OF THE MONEY-MARKET YIELD CURVE INFLUENCE THE FUND'S
INVESTMENT DECISIONS?

During the reporting period, the money-market yield curve, as measured by the
difference between the overnight federal funds rate and 12-month LIBOR,(1) was
generally upward sloping, although there was some volatility in the money
markets. In December 2004, the money-market yield curve reached its lowest
level, a 69 basis point difference between the overnight federal funds rate and
12-month LIBOR. During March 2005, the difference reached 118 basis points.

The Fund was able to opportunistically benefit from the steepening money-market
yield curve by purchasing securities with longer maturities that offered higher
yields. For example, we purchased some 3.05% HBOS Treasury Services Yankee CDs
due December 30, 2005, and 2.78% World Omni Auto Receivables due February 12,
2006.

HOW DID THE FUND INVEST DURING THE REPORTING PERIOD?

Commercial paper, which provides a high degree of liquidity, continued to be the
key market sector for the Fund during the reporting period. We also looked for
yield-enhancement opportunities in the short-term corporate-note sector. Among
short corporates, some of the Fund's key investments included notes of Alabama
Power, Bank One, Goldman Sachs Group, and 3M.

We also added incremental yield through investments in the asset-backed and
floating-rate securities sectors, although we gave up some liquidity in the
process. During the reporting period, we purchased asset-backed securities
issued by Capital One Prime Auto, USAA Auto Owner, Nissan Auto Receivables,
World Omni Auto Receivables, and Caterpillar Financial Asset. Among
floating-rate securities, we bought JP Morgan Chase, Nationwide Building
Society, UBS, and TIAA Global Markets for the Fund. We also purchased Yankee
certificates of deposit for the Fund, including issues by BNP Paribas, HBOS
Treasury Services, Toronto Dominion Bank, and Suntrust Bank.


AN INVESTMENT IN THE FUND IS NOT INSURED OR GUARANTEED BY THE FEDERAL DEPOSIT
INSURANCE CORPORATION OR ANY OTHER GOVERNMENT AGENCY. ALTHOUGH THE FUND SEEKS TO
PRESERVE THE VALUE OF YOUR INVESTMENT AT $1.00 PER SHARE, IT IS POSSIBLE TO LOSE
MONEY BY INVESTING IN THE FUND.
Foreign securities may be subject to greater risks than U.S. investments,
including currency fluctuations, less-liquid trading markets, greater price
volatility, political and economic instability, less publicly available
information, and changes in tax or currency laws or monetary policy. These risks
are likely to be greater in emerging markets than in developed markets. The Fund
may invest in derivatives, which may increase the volatility of the Fund's net
asset value and may result in a loss to the Fund.

   widely used as a base rate in bank, corporate, and government lending
   agreements.

DID THE FUND CHANGE ITS ASSET CLASS WEIGHTINGS?

In an effort to add incremental yield to the portfolio, we increased the Fund's
weighting in short-term corporate notes. In so doing, we decreased the Fund's
weighting in commercial paper.

WHAT IS YOUR OUTLOOK FOR THE FUND?

Looking forward, we expect the Federal Open Market Committee to continue to
raise the federal funds target rate throughout 2005. To meet the Fund's
investment objective, our strategy will remain focused on keeping the Fund's
weighted average maturity short and seeking securities that are likely to
benefit from higher short-term interest rates.

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY FLOATING RATE FUND

The example below is intended to describe the fees and expenses borne by
shareholders during the reporting period 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, if applicable, exchange fees, and sales
charges (loads) on purchase payments, and (2) ongoing costs, including
management fees, distribution and/or service (12b-1) fees, and other Fund
expenses. 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 November 1, 2004, to April 30, 2005.

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 over the period. 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 balance or
expenses you paid for the period. You may use this information to compare the
ongoing costs of investing in the Fund and 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 Robert Dial and Anthony Malloy of New
York Life Investment Management LLC

CAN YOU BRIEFLY DESCRIBE THE FUND'S INVESTMENT APPROACH?

The Fund normally invests at least 80% of its assets in a portfolio of
floating-rate loans and other floating-rate debt securities. The Fund may also
purchase fixed-income debt securities and money-market securities or
instruments. When we believe that market or economic conditions are unfavorable
to investors, up to 100% of the Fund's assets may be invested in money-market or
short-term debt securities. The Fund may also invest in these types of
securities or hold cash while we are looking for suitable investment
opportunities or to maintain liquidity.

In implementing this strategy, we seek to identify investment opportunities
based on the financial condition and competitiveness of individual companies. We
also seek to invest in companies that have a high margin of safety and are
leaders in industries with high barriers to entry. We prefer companies with
positive free cash flow, solid asset coverage, and management teams that have
strong track records. In virtually every phase of the investment process, we
attempt to control risk and limit defaults.

WHAT WERE THE MOST SIGNIFICANT FACTORS AND RISKS THAT INFLUENCED THE
FLOATING-RATE LOAN MARKET DURING THE SIX MONTHS ENDED APRIL 30, 2005?

The Federal Open Market Committee met four times during the six months ended
April 30, 2005, and raised its target for the federal funds rate 25 basis points
at each meeting. (A basis point is 1/100th of one percentage point.) These rate
hikes raised the targeted federal funds rate from 1.75% at the end of October
2004 to 2.75% at the end of April 2005. As a result, reference U.S. dollar
London interbank offer rates (LIBOR)(1) rose commensurately. Rising reference
rates prompted strong investor interest in floating-rate loans during the
reporting period. In recent periods, growing demand for these securities has
caused the median new-issue allocation level granted to market participants to
decline substantially. Demand growth has also caused credit spreads(2) to narrow
and prices to remain relatively high in the secondary market (as tracked by the
Credit Suisse First Boston(TM) Leveraged Loan Index).(3) Since LIBOR has risen
more than credit spreads have declined, however, the Fund experienced a rising
yield during the reporting period.

HOW DID YOU POSITION THE FUND'S PORTFOLIO DURING THE REPORTING PERIOD?

The Fund invests in floating-rate loans that have a weighted average effective
duration of less than three months. These securities may have final maturities
of seven to nine years, but their underlying interest-rate contracts are
typically pegged to LIBOR and generally reset every 30, 60, or 90 days. As of
the end of April 2005, the weighted average reset figure for the Fund was 56
days. This means that as short-term interest rates increase, the Fund tends to
adjust within 56 days, raising the yield it pays to investors. An inverse
dynamic would apply when interest rates decline. As of April 30, 2005, the
Fund's portfolio had a weighted average spread of 243.5 basis points above the
weighted average LIBOR reference rate.

WHAT WERE THE MAJOR FACTORS THAT AFFECTED THE FUND'S PERFORMANCE DURING THE
REPORTING PERIOD?

The Fund's comparative benchmark is the Credit Suisse First Boston(TM) Leveraged
Loan Index (the Index). Excluding all sales charges, for the six months ended
April 30, 2005, Class A shares returned 1.71% and Class B and Class C shares
returned 1.33%. Over the same period, Class I shares returned 1.83%.(4) These
returns were lower than the Index return of 2.72% for several reasons. First,
the Fund faces real-world expenses that a hypothetical index does not. Second,
for liquidity purposes, the Fund maintains prudent cash balances as appropriate
for an open-ended Fund with longer-settlement assets. Third, higher Fund net
yields resulted in significant cash inflows, especially during March and April
2005. These inflows temporarily increased the Fund's cash

Floating-rate funds are generally considered to have speculative characteristics
that involve default risk of principal and interest, collateral impairment,
nondiversification, borrower industry concentration, and limited liquidity. The
Fund may invest in foreign securities. U.S. dollar denominated securities of
foreign issuers may be subject to greater risks than U.S. investments, including
currency fluctuations, less-liquid trading markets, greater price volatility,
political and economic instability, less publicly available information, and
changes in tax or currency laws or monetary policy.

   widely used as reference rates in bank, corporate, and government lending
   agreements.
2. The term "credit spread" refers to the marginal interest rate paid in
   addition to a benchmark interest rate linked to a market, index, or
   instrument.

position from 11% to 14%. The higher cash position and the lag associated with
the longer-settlement nature of the loans asset class contributed to relative
underperformance. Fourth, amortization of secondary-market purchase premiums
affected relative returns, because the Index tracks assets at primary-issue
prices, which are generally at par or a small discount. Fifth, the conservative
orientation of the Fund affected relative performance. In an effort to minimize
net-asset-value volatility, the Fund holds a significantly underweighted
position relative to the Index in more speculative loans, including unrated
loans and loans rated CCC(5) and below.

It is worth noting that the Fund pays a floating-rate dividend, unlike the
Index, which does not pay dividends. The Fund's 30-day yield on April 30, 2005,
was 4.05%.

WHICH INDUSTRIES DID YOU FIND ATTRACTIVE DURING THE PERIOD?

The largest industry concentrations in the Fund were broadcasting & cable TV
(10.06% of net assets), health care (9.32%), chemicals (7.98%), utilities
(7.48%), and consumer non-durable goods (6.61%). Among its largest industry
concentrations, the Fund was overweighted relative to the Index in health care,
chemicals, utilities, and nondurable consumer goods. We felt comfortable with
overweighted positions in health care and nondurable consumer goods because of
the defensive nature of the industries. We overweighted the chemicals and
utilities sectors for the historically strong cash flow and because issuers in
these sectors typically provide substantial collateral coverage. The Fund held a
modestly underweighted position relative to the Index in broadcasting & cable TV
because of relative value judgments.

HOW WAS THE FUND'S PORTFOLIO POSITIONED IN TERMS OF CREDIT QUALITY?

As we mentioned, the Fund was significantly underweighted relative to the Credit
Suisse First Boston(TM) Leveraged Loan Index in unrated loans and loans rated
CCC or below. As of April 30, 2005, the Fund held 0.39% of its investments in
loans rated CCC or lower, compared to 3.38% for the Index. At the same time, the
Fund held 1.21% in unrated loans, compared to 7.42% in the Index. The Fund had a
weighted average credit rating of approximately Ba3/B1 from Moody's(6) and
BB-/B+ from Standard & Poor's.(7)

WHAT DO YOU ANTICIPATE GOING FORWARD?

We expect further Federal Open Market Committee tightening in 2005, which should
continue to bolster investor demand in the floating-rate loan asset class. The
combination of a growing economy, low default rates, and strong technicals will
likely enable deals with higher leverage and looser covenants to clear the
market. In fact, leverage has already crept

5. 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.
6. Bonds rated Ba by Moody's Investors Service are judged by Moody's to have
   speculative elements, and Moody's believes that the future of the bonds
   cannot be considered well-assured. Moody's believes that often, the
   protection of interest and principal payments on such bonds may be very
   moderate and thereby not well safeguarded during both good and bad times in
   the future. According to Moody's, uncertainty of position characterizes bonds
   in this class. Bonds rated B by Moody's Investors Service are deemed by
   Moody's to generally lack characteristics of the desirable investment.
   According to Moody's, assurance of interest and principal payments or of
   maintenance of other terms of the contract over any long period of time may
   be small. Moody's applies numerical modifiers, 1, 2, and 3, to certain
   generic rating categories. The modifier 1 indicates that the issue ranks in
   the higher end of its generic rating category; the modifier 2 indicates a
   midrange ranking; and the modifier 3 indicates that the issue ranks in the
   lower end of its generic rating category. 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.
7. Debt rated BB by Standard & Poor's is deemed by Standard & Poor's to be less
   vulnerable to nonpayment than other speculative issues. In the opinion of
   Standard & Poor's, however, debt rated BB faces major ongoing uncertainties
   or exposure to adverse business, financial, or economic conditions which
   could lead to the obligor's inadequate capacity to meet its financial
   commitment on the obligation. Debt rated B by Standard & Poor's is deemed by
   Standard & Poor's to be more vulnerable to nonpayment than obligations rated
   BB, but it is the opinion of Standard & Poor's that the obligor currently has
   the capacity to meet its financial commitment on the obligation. Standard &
   Poor's believes that adverse business, financial, or economic conditions will
   likely impair the obligor's capacity or willingness to meet its financial
   commitment on the obligation. Certain ratings may be modified by the addition
   of a plus or minus sign to show relative standing within the major rating
   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.

                                                   www.mainstayfunds.com     101


upward, primarily because of a growing number of aggressive deals. The average
debt multiple of new, large leveraged buyouts expanded during the reporting
period to its highest reading since 1998. Although difficult to measure,
covenant positions on loans seem to be eroding.

Like most credit markets, the leveraged-loan market seems increasingly
overbought. We expect the spread environment to remain challenging in 2005.
Maintaining appropriate investment levels for the Fund given natural repayments
and refinancing activity will require creativity and careful analysis as we
balance risk against the need to remain fully invested. A resurgence of
merger-and-acquisition-related deal flow, may help to alleviate some of the
spread compression.

Perhaps the greater challenge in this seemingly benign credit environment is to
remain focused on conditions that may affect credit quality. We are committed to
capital preservation through fundamental research, underwriting scrutiny, and
constant portfolio surveillance. We believe the Fund is attractively positioned
as we look toward the second half of 2005.

(a)  May be sold to institutional investors only.
(b)  Floating Rate Loans generally pay interest at rates which are periodically
     re-determined at a margin above the London Inter-Bank Offered Rate
     ("LIBOR") or other short-term rates. The rate show is the rate(s) in effect
     at April 30, 2005. Floating Rate Loans are generally considered restrictive
     in that the Fund is ordinarily contractually obligated to receive consent
     from the Agent Bank and/or borrower prior to disposition of a Floating Rate
     Loan (see Note 2(H)).
(c)  This security has additional commitments and contingencies (see Note 6).
(d)  Illiquid security.
(e)  The cost stated also represents the aggregate cost for federal income tax
     purposes.
(f)  At April 30, 2005 net unrealized appreciation was $731,152, based on cost
     for federal income tax purposes. This consisted of aggregate gross
     unrealized appreciation for all investments on which there was an excess of
     market value over cost of $2,271,522 and aggregate gross unrealized
     depreciation for all investments on which there was an excess of cost over
     market value of $1,540,370.

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 change in share price, reinvestment of dividend and capital-gain
distributions, and maximum applicable sales charges explained in this paragraph.
The graphs assume an initial investment of $10,000 and reflect the deduction of
all sales charges that would have applied for the period of investment. Class A
shares are sold with a maximum initial sales charge of 3% and an annual 12b-1
fee of .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 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. The fee waivers and/or expense limitations are
voluntary and may be discontinued at any time. From inception (1/2/91) through
12/31/03, performance for Class A shares (first offered 1/2/04) includes the
historical performance of Class I shares adjusted to reflect the applicable
sales charge and fees and expenses for Class A shares.

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY INDEXED BOND FUND

The example below is intended to describe the fees and expenses borne by
shareholders during the reporting period 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, if applicable, exchange fees, and sales
charges (loads) on purchase payments, and (2) ongoing costs, including
management fees, distribution and/or service (12b-1) fees, and other Fund
expenses. 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 November 1, 2004, to April 30, 2005.

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 over the period. 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 balance or
expenses you paid for the period. You may use this information to compare the
ongoing costs of investing in the Fund and 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 Paul Cunningham and Donald F. Serek of
New York Life Investment Management LLC

CAN YOU BRIEFLY DESCRIBE THE FUND'S INVESTMENT APPROACH?

The Fund normally invests at least 80% of its total assets in fixed-income
securities, including investment-grade corporate bonds, U.S. dollar-denominated
securities of foreign issuers, U.S. Treasury or agency issues, and other
securities. In implementing this strategy, we employ a specialized method to
track the performance of the Citigroup Broad Investment Grade Bond Index (the
BIG Index).(1) Typically, the Fund does not invest in all of the securities in
the BIG Index. Instead it invests in a representative selection of fixed-income
securities that, in the aggregate, are expected to mirror the performance of the
BIG Index.

WHAT WERE THE MAJOR FACTORS THAT AFFECTED THE INVESTMENT-GRADE BOND MARKET
DURING THE SIX-MONTH REPORTING PERIOD?

Bond prices fluctuated during the Fund's semiannual period in response to the
changing outlook for the U.S. economy and for inflation. As expected, when the
economy appeared to be strengthening or when inflation appeared to be
accelerating, interest rates rose and bond prices fell. (Interest rates and bond
prices tend to move in opposite directions.) On the other hand, when the
economic recovery appeared to be losing momentum or when inflation appeared to
be decelerating, interest rates declined and bond prices rose.

During the reporting period, the Federal Open Market Committee raised interest
rates 25 basis points on four separate occasions--in November and December 2004
and in February and March 2005. (A basis point is 1/100th of one percentage
point.) These four rate hikes brought the targeted federal funds rate from 1.75%
at the beginning of the reporting period to 2.75% at the end. The 10-year
Treasury note closed the reporting period at 4.20%, although it traded as low as
3.99% in February 2005 and as high as 4.64% in March 2005.

HOW DID YOU POSITION THE FUND DURING THE REPORTING PERIOD?

The Fund seeks to track the total-return performance of the BIG Index. Since the
Fund does not hold every security in the Index, the Fund's performance will vary
from that of the Index. Aside from activity to accommodate new investments and
share redemptions, most of the Fund's investment activity during the reporting
period was intended to reduce excess exposure of the Fund relative to the
benchmark.

HOW DID THE FUND PERFORM RELATIVE TO THE BIG INDEX?

The Fund's results and those of its benchmark are provided on page 118.
Excluding all sales charges, both share classes of the Fund underperformed the
BIG Index for the six months ended April 30, 2005, largely because of sector and
issue selection. Of course, the Fund incurs expenses that an unmanaged index
does not. As a result, there are times when the Fund's performance will lag the
Index.

HOW DID THE VARIOUS SECTORS OF THE BIG INDEX PERFORM?

For the six months ended April 30, 2005, mortgage-backed securities showed the
strongest performance, with a total return of 1.43%.(2) In the credit component
of the BIG Index, A-rated bonds(3) returned


Index funds generally seek to reflect the performance of an index or an
allocation among indices, unlike other funds, whose objectives may, in some
cases, involve seeking to outperform an index or other benchmark. Foreign
securities may be subject to greater risks than U.S. investments, including
currency fluctuations, less-liquid trading markets, greater price volatility,
political and economic instability, less publicly available information, and
changes in tax or currency laws or monetary policy. These risks are likely to be
greater in emerging markets than in developed markets. The Fund may invest in
derivatives, which may increase the volatility of the Fund's net asset value and
may result in a loss to the Fund. Funds that invest in bonds are subject to
credit, inflation, interest- rate, and maturities risk and can lose principal
value when interest rates rise. The Fund may experience a turnover rate of 100%,
which may generate short-term capital gains, which are taxable to the
shareholder.
1. See footnote on page 118 for more information on the Citigroup Broad
   Investment Grade Bond Index.
2. Performance figures represent total-return performance for BIG Index
   securities in the sectors mentioned. Since the Fund does not invest in all of
   the securities in the Index, Fund results may differ.
3. Debt rated AA by Standard & Poor's is deemed by Standard & Poor's to differ
   from the highest-rated issues only in small degree. In the opinion of
   Standard & Poor's, the obligor's capacity to meet its financial commitment on
   the obligation is very strong. Debt rated A by Standard & Poor's is deemed by
   Standard & Poor's to be somewhat more susceptible to the adverse effects of
   changes in circumstances and economic conditions than debt in higher-rated
   categories. In the opinion of Standard & Poor's, however, the obligor's
   capacity to meet its financial commitment on the obligation is still 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. 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.

1.29%, and AA-rated bonds returned 0.58%. At -0.10%, bonds rated BBB provided
the weakest performance.

WHAT IS YOUR OUTLOOK FOR THE ECONOMY AND THE FUND?

As we approach the middle of 2005, we believe that the performance of the
investment-grade fixed-income market and the Fund may be affected by several
factors. Economic reports that indicate strength in the economy--such as an
improving job market or heightened inflation--will likely cause interest rates
to rise. Other concerns, such as geopolitical unrest, terrorism, and
issuer-specific uncertainties, could also have an impact on the bond market and
on the Fund.

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 change in share price, reinvestment of dividend and capital-gain
distributions, and maximum applicable sales charges explained in this paragraph.
The graphs assume an initial investment of $10,000 and reflect the deduction of
all sales charges that would have applied for the period of investment. Class A
shares are sold with a maximum initial sales charge of 4.5% and an annual 12b-1
fee of .25%. Class B shares are sold with no initial sales charge, are subject
to a contingent deferred sales charge (CDSC) of up to 5% 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% 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
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. The fee waivers and/or expense limitations are voluntary and
may be discontinued at any time. From inception (1/2/91) through 12/31/03,
performance for Class A, B, and C shares (each first offered 1/2/04) includes
the historical performance of Class I shares adjusted to reflect the applicable
sales charge (or CDSC) and fees and expenses for Class A, B, and C shares.

THE DISCLOSURE AND FOOTNOTES ON THE NEXT PAGE ARE AN INTEGRAL PART OF THE TABLES

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY INTERMEDIATE TERM BOND FUND

The example below is intended to describe the fees and expenses borne by
shareholders during the reporting period 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, if applicable, exchange fees, and sales
charges (loads) on purchase payments, and (2) ongoing costs, including
management fees, distribution and/or service (12b-1) fees, and other Fund
expenses. 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 November 1, 2004, to April 30, 2005.

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 over the period. 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 balance or
expenses you paid for the period. You may use this information to compare the
ongoing costs of investing in the Fund and 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 Gary Goodenough and Christopher Harms
of MacKay Shields LLC

CAN YOU BRIEFLY DESCRIBE THE FUND'S INVESTMENT APPROACH?

The Fund normally invests at least 80% of its assets in bonds, and at least 65%
of its total assets will be invested in debt securities rated Baa or better by
Moody's Investors Service, Inc.,(1) or BBB or better by S&P when purchased, or
if unrated, determined to be of comparable quality. The effective maturity of
the portfolio is usually in the three- to 10-year range. The Fund may invest in
both U.S. and foreign debt securities. In implementing this strategy, we conduct
a continuing review of yields and other information from a proprietary data
base. Among the principal factors we consider in determining whether to increase
or decrease the emphasis placed upon a particular type of security or industry
sector are fundamental economic cycle analysis, credit quality, and interest
rate trends. We make shifts in maturity based on a broad range of fundamental
and technical indicators.

WHAT ECONOMIC FORCES AFFECTED THE BOND MARKET DURING THE SIX MONTHS ENDED APRIL
30, 2005?

The U.S. economy grew at its historical average pace during the reporting
period, and corporate profitability remained solid. Consumer-related
inflationary pressures were absent, because businesses could not meaningfully
increase prices. The Federal Reserve maintained its policy of gradually raising
interest rates. During the reporting period, the Federal Open Market Committee
increased the targeted federal funds rate four times, with a 25 basis point move
on each occasion. This brought the federal funds target rate to 2.75% at the end
of April 2005.

HOW DID THESE FACTORS AFFECT TREASURY YIELDS?

U.S. Treasury yields showed contrasting price action in the early and late
portions of the reporting period. From November 2004 through February 2005,
Treasurys traded in a fairly narrow range, which hinted that the bond market and
the economy had settled into a comfort zone. Treasurys turned more volatile in
the final two months of the reporting period. Yields rose in March because of
inflationary concerns but then retreated to their prior levels on a "soft patch"
of economic data in April.

Looking at the period as a whole, the Treasury yield curve flattened. The
longer-end of the yield curve was supported by solid demand from foreign
investors and pension funds. Short-term yields were pushed higher as the Federal
Reserve tightened monetary policy. During the six-month period, two-year
Treasury yields rose from 2.56% to 3.65%, five-year Treasurys advanced from
3.29% to 3.90%, 10-year Treasurys climbed a modest 17 basis points from 4.03% to
4.20%, and 30-year Treasury yields declined from 4.79% to 4.52%.

HOW DID YOU POSITION THE FUND'S PORTFOLIO AMONG THE VARIOUS BOND SECTORS?

As of April 30, 2005, the Fund's net assets were invested 13% in Treasurys, 10%
in agency debentures, 35% in residential mortgage-backed securities issued by
government-sponsored and government-related enterprises, 4% in commercial
mortgage-backed securities, 3% in asset-backed securities, 23% in
investment-grade corporates, 7% in high-yield corporates, and 5% in money-market
instruments. Compared with the Lehman Brothers(R) Aggregate Bond Index,(2) the
Fund held overweighted positions in mortgage-backed securities, asset-backed
securities, high-yield corporates, and money market instruments. The Fund held a
neutral-to-the-Index position in investment-grade corporates and held
underweighted positions in Treasurys and agency debentures.


Foreign securities may be subject to greater risks than U.S. investments,
including currency fluctuations, less-liquid trading markets, greater price
volatility, political and economic instability, less publicly available
information, and changes in tax or currency laws or monetary policy. These risks
are likely to be greater in emerging markets than in developed markets. The Fund
may invest in derivatives, which may increase the volatility of the Fund's net
asset value and may result in a loss to the Fund. Funds that invest in bonds are
subject to credit, inflation, and interest-rate risk and can lose principal
value when interest rates rise.
1. Bonds rated Baa by Moody's Investors Service are considered by Moody's to be
   medium-grade obligations (i.e., obligations that Moody's believes are neither
   highly protected nor poorly secured). It is Moody's opinion that interest
   payments and principal security appear adequate for the present, but that
   certain protective elements may be lacking or may be characteristically
   unreliable over any great length of time. Moody's believes that such bonds
   lack outstanding investment characteristics and that they in fact have
   speculative characteristics as well. 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.

   Aggregate Bond Index.

 146   MainStay Intermediate Term Bond Fund


HOW DID THE FUND'S EXPOSURE TO THE CORPORATE BOND SECTOR IMPACT PERFORMANCE?

The Fund began the reporting period with a 35% allocation to investment-grade
and high-yield corporates. Compared to the 25% credit allocation in the Lehman
Brothers(R) Aggregate Bond Index, the Fund was overweighted by 10 percentage
points (or 40%). This initially enhanced results, as credit spreads tightened
during the fourth quarter of 2004 on the back of declining default rates, lower
volatility in the equity market, and solid demand from investors seeking
incremental yield in a low interest-rate environment.

A benign economic backdrop and worldwide demand for yield carried the strong
momentum into the new year. By March 2005, corporate spreads were reminiscent of
spring 1997, the last quiet period for corporate bonds prior to an annual series
of unsettling events that included the Asian currency crisis, the bursting of
the Nasdaq bubble, September 11, 2001, and the fallout from lax corporate
governance. The market appeared to be growing complacent about event risk, and
we reacted by cutting the Fund's corporate allocation to 31% of net assets.
Since the credit allocation of the Lehman Brothers(R) Aggregate Bond Index
remained at 25%, our adjustment reduced the Fund's corporate overweight to just
six percentage points (or 24%). These actions, however, were not sufficient to
avoid the fallout that occurred when corporate spreads widened over the next two
months of the reporting period.

WHAT DO YOU ANTICIPATE FOR THE ECONOMY AND INTEREST RATES GOING FORWARD?

Looking ahead, it may be difficult to say whether the U.S. economy is best
characterized as a glass half-empty or as a glass half-full. Particular
attention will no doubt be paid to payroll and inflation data. Economic
naysayers typically cite a variety of concerns, including mixed monthly
employment data, sluggish capital spending, a record trade deficit, high oil
prices, and the inflationary effects of a weak U.S. dollar.

An alternate, more constructive, perspective relies on the following lines of
reasoning. The corporate sector may be operating leaner than in past recoveries,
leading to hiring that is less robust. Corporate America has transitioned from a
labor-intensive to a capital-intensive enterprise. The run-up in oil reflects
the tight balance between global supply and demand, and as these transients
pass, prices may retreat to more reasonable levels. The U.S. dollar could
strengthen on its own accord in response to economic growth, and new mortgage
products could extend the refinancing trend. If so, the economy may be in better
shape than a soft patch in April 2005 suggested. This optimistic view is
supported by pockets of data, such as the booming rate of new home sales. The
Federal Reserve clearly believes that a 2.75% targeted federal funds rate
remains accommodative.

HOW ARE YOU POSITIONING THE FUND GIVEN YOUR OUTLOOK?

While the market ruminates over mixed data signals, a short duration is not
advisable, so we have neutralized the Fund's duration posture relative to the
benchmark. We can still implicitly express a bearish interest-rate view
elsewhere in the Fund's portfolio. For example, we favor mortgage-backed
securities backed by 15-year loans, half the term of the traditional 30-year
product, because the durations of these securities are less prone to extend as
Treasury yields rise. A healthy commitment to securitized product complements
the Fund's credit allocation. We believe that the securities offer reasonably
attractive yields relative to Treasurys and that spreads are unlikely to move
much while interest-rate volatility is low. Since market exuberance has
tightened spreads considerably, the Fund cut its corporate exposure in the first
quarter of 2005 and may do so again in the second quarter as investor confidence
wanes and event risk emerges.

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 change in share price, reinvestment of dividend and capital-gain
distributions, and maximum applicable sales charges explained in this paragraph.
The graphs assume an initial investment of $10,000 and reflect the deduction of
all sales charges that would have applied for the period of investment. Class A
shares are sold with a maximum initial sales charge of 3% and an annual 12b-1
fee of .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 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. The fee waivers and/or expense limitations are
voluntary and may be discontinued at any time. From inception (1/2/91) through
12/31/03, performance for Class A shares (first offered 1/2/04) includes the
historical performance of Class I shares adjusted to reflect the applicable
sales charge and fees and expenses for Class A shares.

1. The Citigroup 1-3 Year Treasury Index is an unmanaged index comprised of U.S.
   Treasury notes and bonds with maturities of one year or greater, but less
   than three years (minimum amount outstanding is $1 billion per issue).
   Results assume reinvestment of all income and capital gains. An investment
   cannot be made directly into an index.
2. MainStay Short Term Bond Fund, going forward, will measure its performance
   against the Citigroup 1-3 Year U.S. Treasury Agency Index. The Citigroup 1-3
   Year U.S. Treasury Agency Index is an unmanaged index that is comprised of
   U.S. Treasury notes (minimum amount outstanding is $1 billion per issue) and
   agency securities (minimum amount outstanding is $200 million per issue) with
   maturities of one year or greater, but less than three years. Results assume
   reinvestment of all income and capital gains. The Citigroup 1-3 Year U.S.
   Treasury Agency Index is considered to be the Fund's broad-based securities

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY SHORT TERM BOND FUND

The example below is intended to describe the fees and expenses borne by
shareholders during the reporting period 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, if applicable, exchange fees, and sales
charges (loads) on purchase payments, and (2) ongoing costs, including
management fees, distribution and/or service (12b-1) fees, and other Fund
expenses. 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 November 1, 2004, to April 30, 2005.

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 over the period. 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 balance or
expenses you paid for the period. You may use this information to compare the
ongoing costs of investing in the Fund and 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 Claude Athaide, Ph.D., CFA, and Gary
Goodenough of MacKay Shields LLC

CAN YOU BRIEFLY DESCRIBE THE FUND'S INVESTMENT APPROACH?

The Fund normally invests at least 80% of its assets in an actively managed,
diversified portfolio of fixed-income securities. Normally, the Fund will have a
dollar-weighted average maturity of three years or less. In implementing this
strategy, we continually review yields and other information derived from
databases that we maintain to manage fixed-income portfolios. Fundamental
economic cycle analysis, credit quality, and interest rate trends are the
principal factors that we consider in determining whether to increase or
decrease the investment emphasis placed on a particular type of security or
industry sector within the Fund's portfolio.

WHAT WAS THE ECONOMIC AND INTEREST-RATE ENVIRONMENT DURING THE REPORTING PERIOD?

According to preliminary estimates, real gross domestic product increased at a
seasonally adjusted annual rate of 3.5% in the first quarter of 2005, after
growing 3.8% in the fourth quarter of 2004. The Federal Open Market Committee
met four times during the six months ended April 30, 2005, and raised the
targeted federal funds rate 25 basis points at each meeting. (A basis point is
1/100th of one percentage point.) These four rate hikes brought the targeted
federal funds rate from 1.75% at the beginning of the reporting period to 2.75%
at the end of April. During the six-month period, yields on two-year Treasury
notes rose from 2.56% to 3.65%. The yield curve flattened substantially during
the six-month reporting period.

HOW DID THE FUND INVEST DURING THE REPORTING PERIOD?

The Fund was positioned to benefit from a flattening yield curve during the
reporting period. In fact, the spread(1) between one-year and three-year
constant-maturity Treasurys declined from 54 basis points to 40 basis points
during the six-month period.

Shorter-maturity agency-security spreads were generally unchanged over the six
months ended April 30, 2005, while longer-maturity agency-security spreads
tightened. Swap spreads(2) and corporate spreads widened. Spreads in the
automotive sector of the corporate bond market were extremely volatile, since
both General Motors and Ford issued profit warnings during the period. We
reduced the Fund's exposure to corporate bonds from about 17.6% to 5.1% during
the six-month period and reallocated those assets primarily into U.S. Treasurys.
As a result, the Fund's allocation to U.S. Treasurys increased from 33.4% at the
end of October 2004 to approximately 49% at the end of April 2005.

WHAT DO YOU ANTICIPATE GOING FORWARD?

Economic data released in April 2005 was generally weaker than the markets
expected, sparking a decline in interest rates. The yield on the benchmark
two-year Treasury note declined from 3.79% to 3.65% during the month of April.
At the same time, statements from the Federal Open Market Committee became
noticeably more hawkish, especially with respect to the inflation outlook.

Given this environment, we allowed the duration of the Fund to shorten relative
to the Citigroup 1-3 Year U.S. Treasury Agency Index(3) toward the end of the
reporting period, because we felt that the difference between the yield on the
two-year Treasury note and the targeted federal funds rate was too small. We
intend to maintain this shorter duration until market conditions change.


The Fund may invest in derivatives, which may increase the volatility of the
Fund's net asset value and may result in a loss to the Fund. Funds that invest
in bonds are subject to credit, inflation, and interest-rate risk and can lose
principal value when interest rates rise.
1. The terms "spread" and "yield spread" refer to the difference in yield
   between a specific 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.
2. The term "swap spread" refers to the difference in yield between a fixed
   interest-rate swap and a U.S. Treasury bond of equal maturity. For example, a
   10-year swap, bid at 7.66% when the 10-year Treasury is yielding 7.32%, has a
   swap spread of 34 basis points (7.66% - 7.32%). A bond swap is the
   simultaneous sale of one bond issue and purchase of another. Yield swaps seek
   to improve return.
3. See footnote on page 163 for more information about the Citigroup 1-3 Year
   U.S. Treasury Agency Index.

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 change in share price, reinvestment of dividend and capital-gain
distributions, and maximum applicable sales charges explained in this paragraph.
The graphs assume an initial investment of $10,000 and reflect the deduction of
all sales charges that would have applied for the period of investment. Class A
shares are sold with a maximum initial sales charge of 5.5% and an annual 12b-1
fee of .25%. Class B shares are sold with no initial sales charge, are subject
to a contingent deferred sales charge (CDSC) of up to 5% 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% 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
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. The fee waivers and/or expense limitations are voluntary and

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY ASSET MANAGER FUND

The example below is intended to describe the fees and expenses borne by
shareholders during the reporting period 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, if applicable, exchange fees, and sales
charges (loads) on purchase payments, and (2) ongoing costs, including
management fees, distribution and/or service (12b-1) fees, and other Fund
expenses. 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 November 1, 2004, to April 30, 2005.

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 over the period. 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 balance or
expenses you paid for the period. You may use this information to compare the
ongoing costs of investing in the Fund and 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 Tony Elavia and Devon McCormick of New
York Life Investment Management LLC

CAN YOU BRIEFLY DESCRIBE THE FUND'S INVESTMENT APPROACH?

The Fund normally invests in three asset classes, subject to the following
constraints: 30% to 80% of its net assets in common stocks (with specific
allocation ranges for stocks that seek to track the performance of the S&P
500(R) Index, the S&P MidCap 400(R) Index, the S&P SmallCap 600(R) Index, and
the Morgan Stanley REIT(R) Index),(1) 10% to 60% of its net assets in
fixed-income securities selected to parallel the performance of the Citigroup
BIG Bond Index,(2) and 10% to 60% of its net assets in selected money-market
instruments. In implementing this strategy, we use a disciplined methodology to
determine the best allocation within the Fund's percentage constraints. We use a
proprietary model to estimate expected returns, volatilities, and correlations
on domestic and foreign stock markets and on domestic fixed-income securities.
The Fund's allocations among stocks, bonds, and money-market securities are
structured to take advantage of perceived imbalances in relative pricing.

WHAT WERE SOME OF THE MAJOR MARKET FACTORS THAT AFFECTED THE FUND'S PERFORMANCE
DURING THE REPORTING PERIOD?

For the six months ended April 30, 2005, the broadly watched equity indices
produced mixed results. During this period, mid-cap stocks performed relatively
better than their large- and small-cap counterparts. The market clearly favored
value equities over growth stocks for large- and mid-cap issues, although
different data sources suggested different style preferences among small-cap
issues.(3) Throughout much of the reporting period, the domestic equity market
was influenced by crude-oil price fluctuations, job-growth concerns, the U.S.
dollar's decline, and continuing instability in the Middle East.

HOW DID YOU POSITION THE FUND'S PORTFOLIO DURING THE SIX MONTHS ENDED APRIL 30,
2005?

During the reporting period, the Fund had an average allocation of 56% in
equities, 32% in bonds, and 12% in cash. Within the equity allocation, U.S.
equities were underweighted relative to the Fund's custom benchmark(4) by 12
percentage points, international equities were overweighted by 7 percentage
points, and REITs were overweighted by 1 percentage point. While the custom
benchmark allocates 60% to U.S. equities, the Fund's allocation averaged 48%.
Although the custom benchmark has no allocation to international equities or
REITs, international equities averaged 7% of net assets in the Fund's portfolio
and REITs averaged 1%.

HOW DID THE FUND'S EQUITIES PERFORM?

All foreign markets in the investable universe, with the exception of Japan and
Germany, outperformed the U.S. during the six-month reporting period. The
decision to invest in the equity markets of Australia (+6.16%),(5) Hong Kong
(+6.54%), Italy (+7.11%), and Spain (+6.93%) proved beneficial for the six
months ended April 30, 2005.

The economy appears to be well on its way to recovery after the 2001 recession,
and the Federal Reserve is now trying to ease inflation.


Foreign securities may be subject to greater risks than U.S. investments,
including currency fluctuations, less-liquid trading markets, greater price
volatility, political and economic instability, less publicly available
information, and changes in tax or currency laws or monetary policy. These risks
are likely to be greater in emerging markets than in developed markets. Stocks
of small companies may be subject to greater price volatility, significantly
lower trading volumes, and greater spreads between bid and ask prices than
stocks of larger companies. Small companies may be more vulnerable to adverse
business or market developments than mid- or large- capitalization companies.
The Fund may invest in derivatives, which may increase the volatility of the
Fund's net asset value and may result in a loss to the Fund.

3. Specifically, for the six months ended April 30, 2005, the Russell 2000(R)
   Growth Index underperformed the Russell 2000(R) Value Index, while the S&P
   SmallCap 600/Barra Growth Index outperformed the S&P SmallCap 600/Barra Value
   Index. Each of these indices is unmanaged, contains different issues, and is
   considered to be generally representative of small-cap growth or small-cap
   value stocks, as the index name suggests. An investment cannot be made
   directly into an index.

 180   MainStay Asset Manager Fund


In four separate moves during the reporting period, the Federal Open Market
Committee gradually raised the targeted federal funds rate from 1.75% on October
31, 2004, to 2.75% on April 30, 2005. The rising rate environment hurt the
Fund's REIT component.

DID THE FUND'S BOND ALLOCATION HELP RESULTS?

The bond portion of the Fund's portfolio showed strong relative performance,
largely because of sector and issue selection. Of course, the Fund incurs
expenses that an unmanaged index does not. As a result, there will be times when
the bond portion of the Fund will lag the BIG Index.

For the six months ended April 30, 2005, the mortgage-backed securities of the
BIG Index showed the strongest performance, with a total return of 1.43%. In the
credit component of the BIG Index, A-rated bonds(6) returned 1.29%, and AA-rated
bonds returned 0.58%. At -0.10%, bonds rated BBB provided the weakest
performance.

HOW DID THE ACTIVELY MANAGED SEGMENTS OF THE FUND AFFECT RESULTS?

The Fund's allocation to an actively managed enhanced index fund helped returns,
since this portion of the Fund's portfolio outperformed the S&P 500(R) Index by
94 basis points for the reporting period. Similarly, the Fund's allocation to
the actively managed mid-cap strategy enhanced results, because this portion of
the Fund's portfolio outperformed the S&P MidCap 400(R) Index by 115 basis
points. The Fund's allocation to the actively managed fixed-income strategy
fared well, since this portion of the Fund's portfolio outperformed the
Citigroup BIG Bond Index by 19 basis points.

WHAT IS YOUR OUTLOOK FOR THE MARKETS AND THE FUND?

While many factors may influence the stock and bond markets, we will continue to
rely on our proprietary asset-allocation model to determine which asset classes
offer the greatest investment potential. We will continue to select investments
for the Fund's portfolio within the allocation constraints outlined in the
prospectus.


6. Debt rated AA by Standard & Poor's is deemed by Standard & Poor's to differ
   from the highest-rated issues only in small degree. In the opinion of
   Standard & Poor's, the obligor's capacity to meet its financial commitment on
   the obligation is very strong. Debt rated A by Standard & Poor's is deemed by
   Standard & Poors to be somewhat more susceptible to the adverse effects of
   changes in circumstances and economic conditions than debt in higher-rated
   categories. In the opinion of Standard & Poor's, however, the obligor's
   capacity to meet its financial commitment on the obligation is still 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. 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.

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 change in share price, reinvestment of dividend and capital-gain
distributions, and maximum applicable sales charges explained in this paragraph.
The graphs assume an initial investment of $10,000 and reflect the deduction of
all sales charges that would have applied for the period of investment. Class A
shares are sold with a maximum initial sales charge of 5.5% and an annual 12b-1
fee of .25%. Class B shares are sold with no initial sales charge, are subject
to a contingent deferred sales charge (CDSC) of up to 5% if redeemed within the
first six years of purchase, and

THE DISCLOSURE AND FOOTNOTES ON THE NEXT TWO PAGES ARE AN INTEGRAL PART OF THE
TABLES AND GRAPHS AND SHOULD BE CAREFULLY READ IN CONJUNCTION WITH THEM.

1. The Fund's Balanced Composite Index is comprised of the Russell Midcap(R)
   Value Index and the Merrill Lynch Corporate and Government 1-10 Years Bond
   Index weighted 60%/40%. The Russell Midcap(R) Value Index is an unmanaged
   index that measures the performance of those Russell Midcap(R) companies with
   lower price-to-book ratios and lower forecasted growth values. Results assume
   reinvestment of all income and capital gains. The Fund's Balanced Composite
   Index is considered to be the Fund's broad-based securities-market index for
   comparison purposes. An investment cannot be made directly into an index or a
   composite.
2. The Merrill Lynch Corporate & Government 1-10 Years Bond Index is a
   market-capitalization-weighted index including U.S. government and
   fixed-coupon domestic investment-grade corporate bonds. Results assume
   reinvestment of all income and capital gains. An investment cannot be made
   directly into an index.
3. The Russell Midcap(R) Index is an unmanaged index that measures the
   performance of the 800 smallest companies in the Russell 1000(R) Index,
   which, in turn, is an unmanaged index that measures the performance of the
   1,000 largest U.S. companies based on total market capitalization. Results
   assume reinvestment of all income and capital gains. An investment cannot be
   made directly into an index.
4. "S&P 500(R)" is a trademark of The McGraw-Hill Companies, Inc. The S&P 500(R)
   is an unmanaged index and is widely regarded as the standard for measuring
   large-cap U.S. stock-market performance. Results assume reinvestment of all
   income and capital gains. An investment cannot be made directly into an

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY BALANCED FUND

The example below is intended to describe the fees and expenses borne by
shareholders during the reporting period 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, if applicable, exchange fees, and sales
charges (loads) on purchase payments, and (2) ongoing costs, including
management fees, distribution and/or service (12b-1) fees, and other Fund
expenses. 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 November 1, 2004, to April 30, 2005.

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 over the period. 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 balance or
expenses you paid for the period. You may use this information to compare the
ongoing costs of investing in the Fund and 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 Tony Elavia and Joan M. Sabella of New
York Life Investment Management LLC

CAN YOU BRIEFLY DESCRIBE THE FUND'S INVESTMENT APPROACH?

The Fund invests approximately 60% of its assets in stocks and 40% of its assets
in fixed-income securities (such as bonds) and cash equivalents. By including
both stocks and bonds, the Fund seeks a balance between capital gains from stock
appreciation and current income from interest and dividends. In implementing
this strategy, the Fund generally invests in dividend-paying mid-capitalization
stocks that have been determined to have strong or improving operating
characteristics and to be relatively overlooked or undervalued by the market.
The Fund uses a quantitative and statistical model to analyze the relative
quality and value of stocks. The Fund selects fixed-income securities based on
their credit quality and duration.

During the reporting period, all of the assets and liabilities of MainStay
Strategic Value Fund were transferred to MainStay Balanced Fund in exchange for
shares of MainStay Balanced Fund.

WHAT MAJOR FACTORS INFLUENCED THE STOCK AND BOND MARKETS DURING THE SIX MONTHS
ENDED APRIL 30, 2005?

During the six months ended April 30, 2005, most broadly watched equity indices
saw positive performance, but small-cap core and growth indices declined.
Mid-capitalization stocks showed the strongest overall performance, followed by
large- and then small-capitalization stocks. The market's general preference for
value equities over growth stocks was clearly evident among mid-capitalization
issues. During the reporting period, the domestic equity market was influenced
by crude-oil price fluctuations, job-growth concerns, the U.S. dollar's decline,
and continuing instability in the Middle East.

The Federal Open Market Committee raised the federal funds target rate four
times during the six months ended April 30, 2005. That brought the targeted
federal funds rate from 1.75% at the beginning of the reporting period to 2.75%
at the end. The economy appears to be well on its way to recovery after the 2001
recession, and the Federal Reserve is now trying to ease inflation. The 10-year
Treasury note stood at 4.20% at the end of April 2005, compared to 4.02% at the
end of October 2004.

HOW DID THE FUND PERFORM IN THIS MARKET ENVIRONMENT?

All share classes of MainStay Balanced Fund underperformed the Fund's Balanced
Composite Index(1) for the semiannual period ended April 30, 2005. The stock and
bond portions of the Fund both underperformed their respective components of the
Balanced Composite Index.

The equity portion of the Fund's portfolio was hurt by weakness in its
technology hardware & equipment and real estate holdings relative to peer stocks
in the Russell Midcap(R) Value Index.(2) The utilities industry group had strong
performance for the six-month reporting period, but the Fund's underweighted
position relative to the Russell Midcap(R) Value Index detracted from the Fund's
relative performance.

The Russell Midcap(R) Value Index is a capitalization-weighted index, which
means that it has larger weightings among securities with larger market
capitalizations. MainStay Balanced Fund attempts to have equal weights among the
equity holdings in its portfolio.

For the six months ended April 30, 2005, the Russell Midcap(R) Value Index was
approximately 50% weighted in the top 25% of Index companies (from largest
market capitalization to smallest). This significantly contributed to the return
of the Russell Midcap(R) Value Index. On the other hand, MainStay Balanced Fund
was weighted only 35% in the top 25% of Index companies with rank determined by
market capitalization. This underweighted position and lower overall exposure to
the top 25% of companies relative to the Russell Midcap(R) Value Index held back
the relative performance of the equity portion of the Fund.

It is important to note that the equity portion of the Fund was invested in
some, but not all of the companies in the Russell Midcap(R) Value Index.


The Fund is subject to market, interest rate, credit, and maturity risks. The
Fund can invest in foreign securities, which may be subject to greater risks
than U.S. investments, including currency fluctuations, less-liquid trading
markets, greater price volatility, political and economic instability, less
publicly available information, and changes in tax or currency laws or monetary
policy. The Fund may invest in derivatives, which may increase the volatility of
the Fund's net asset value and may result in a loss to the Fund. The Fund's use
of securities lending presents the risk of default by the borrower, which may
also result in a loss to the Fund. The Fund invests in mid-cap stocks which may
be more volatile and less liquid than the securities of larger companies.

   Composite Index.
2. See footnote 1 on page 213 for information about the Russell Midcap(R) Value
   Index. Results assume reinvestment of all income and capital gains. An
   investment cannot be made directly into an index.

 216   MainStay Balanced Fund


HOW DID THE BOND PORTION OF THE FUND PERFORM?

With a return of -0.08%, the fixed-income portion of the Fund slightly
underperformed the +0.08% return of the Merrill Lynch Corporate & Government
1-10 Years Bond Index(3) for the six-month reporting period.

WHICH INDUSTRY GROUPS AND INDIVIDUAL STOCKS PROVIDED THE STRONGEST PERFORMANCE
FOR THE FUND DURING THE REPORTING PERIOD?

In the equity portion of the Fund, the five strongest performing industry groups
were energy; food, beverage & tobacco; utilities; health care equipment &
services; and retailing. Among the strongest contributors to the Fund's equity
performance were petroleum refiner Premcor (+68.8%),(4) refiner Valero Energy
(+61.8%), poultry producer Pilgrim's Pride (+30.0%), refiner and chemical
company Sunoco (+26.0%), and transportation and health care services provider
Laidlaw International (+31.8%).

WHICH INDUSTRY GROUPS AND INDIVIDUAL SECURITIES DETRACTED FROM PERFORMANCE IN
THE EQUITY PORTION OF THE FUND?

The Fund's five weakest-performing industry groups during the six-month
reporting period were technology hardware & equipment, banks, capital goods,
automobiles & components, and telecommunication services. Particularly weak
performers included two steel companies--Steel Dynamics (-27.7%) and Commercial
Metals (-20.6%). Cummins (-16.3%), which provides engines, electric power, and
engine-related products, also detracted from the Fund's equity performance. TCF
Financials (-17.4%), a holding company for TCF National Bank, and Sabre Holdings
(-13.9%), which provides products and technology for the travel industry, were
also among the Fund's five weakest holdings during the reporting period.

WERE THERE ANY SIGNIFICANT EQUITY PURCHASES OR SALES DURING THE REPORTING
PERIOD?

The Fund uses its proprietary model to select stocks that have relatively
improving operating characteristics and are relatively undervalued. One of the
stocks the Fund purchased during the reporting period was Toys "R" Us (+28.6%),
a worldwide retailer of toys, apparel, and other children's products. The Fund
purchased the stock in November 2004. We established a position in Apache
(+9.0%), an energy company, in November 2004 and added to the position in
January 2005. The Fund also established a position in independent oil and gas
exploration and production company Anadarko Petroleum (+8.0%) in November 2004
and added to the position in April 2005. All three of these companies exhibited
improving fundamentals and, according to our proprietary model, were relatively
undervalued at the time of purchase.

The Fund sells stocks that exhibit deteriorating operating results, are
relatively overvalued, or both. In December 2004, the Fund sold its position in
Saks (+17.8%), when the retailer decided to close some of its stores as part of
a reorganization. The Fund sold its entire position in Outback Steakhouse
(+17.4%) in February 2005 when our quantitative model showed that the stock had
become overvalued. Homebuilder Toll Brothers (+17.1%) was sold for a similar
reason in December 2004.

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

The Fund's equity weighting in diversified financials increased from 3.42% at
the end of October 2004 to 7.13% at the end of April 2005. The shift in weight
was the result of new purchases and improved performance of the industry group
relative to other industry groups. Another significant change in the Fund's
industry-group weightings was in commercial services & supplies, which declined
from 6.94% at the beginning of the reporting period to 3.39% on April 30, 2005.
The decline in weight was the result of weak performance.

HOW DID THE FUND'S EQUITY WEIGHTINGS COMPARE WITH THOSE OF THE RUSSELL MIDCAP(R)
VALUE INDEX AT THE END OF THE REPORTING PERIOD?

As of April 30, 2005, the equity portion of the Fund was overweighted relative
to the Russell Midcap(R) Value Index in energy, in the food, beverage & tobacco
industry group, and in banks. During the reporting period, the Fund's
overweighted positions in the energy and in the food, beverage & tobacco
industry groups benefited the Fund's performance. The overweighted position in
banks, however, showed weaker performance than peer stocks in the Russell
Midcap(R) Value Index. As of April 30, 2005, the equity portion of the Fund was
underweighted relative to the Russell Midcap(R) Value Index in the real estate,
utilities, and insurance industry groups.


3. See footnote on page 213 for more information about the Merrill Lynch
   Corporate & Government 1-10 Years Bond Index.
4. Performance percentages reflect total returns of Fund holdings in the
   securities mentioned, including purchases and sales, for the six months ended
   April 30, 2005, or for the portion of the reporting period such securities
   were held in the Fund, if shorter. Securities are mentioned in the order of
   their contribution to Fund performance, which takes total returns and
   weightings both into account.

WERE THERE ANY SIGNIFICANT CHANGES IN THE FIXED-INCOME PORTION OF THE FUND
DURING THE REPORTING PERIOD?

No, there were no significant or strategic purchases or sales for the
fixed-income portion of the Fund. The fixed-income portion of MainStay Balanced
Fund selects short- to intermediate-term bonds from among U.S. government
securities and investment-grade corporate bonds. The Fund may also invest in
mortgage-backed securities, asset-backed securities, and foreign-debt
securities. We maintain a laddered maturity schedule and employ a bottom-up
credit analysis with a controlled duration of three to five years.

WHAT IS YOUR OUTLOOK FOR THE FUTURE?

As always the Fund will continue to focus on securities that are appropriate
given the Fund's stated objective and its valuation, quality, duration, and
maturity parameters.

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY CONSERVATIVE ALLOCATION FUND

The example below is intended to describe the fees and expenses borne by
shareholders during the reporting period 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, if applicable, exchange fees, and sales
charges (loads) on purchase payments, and (2) ongoing costs, including
management fees, distribution and/or service (12b-1) fees, and other Fund
expenses. 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 November 1, 2004, to April 30, 2005.

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 over the period. 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 balance or
expenses you paid for the period. You may use this information to compare the
ongoing costs of investing in the Fund and 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.

 238   MainStay Conservative Allocation Fund


PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

Questions answered by portfolio managers Tony Elavia and Devon McCormick, CFA,
of New York Life Investment Management LLC

CAN YOU BRIEFLY DESCRIBE THE FUND'S INVESTMENT APPROACH?

MainStay Conservative Allocation Fund seeks to achieve its investment objective
by investing in a variety of other MainStay Funds, known as underlying Funds. A
two-stage asset-allocation process includes deciding how much to invest in broad
asset classes and how much to invest in specific underlying Funds. Normally the
Fund invests approximately 60% (within a range of 50% to 70%) of its assets in
underlying fixed-income Funds and approximately 40% (within a range of 30% to
50%) of its assets in underlying equity Funds. The Fund's fixed-income component
may include a money-market component. For cash management purposes, the Fund may
hold a portion of its assets directly in U.S. government securities,
money-market funds, cash, or cash equivalents. The underlying Funds use a broad
array of investment styles; may invest in a wide variety of equity securities,
fixed-income securities, or both; and carry different types and degrees of risk.
Some underlying Funds may invest in foreign securities. The Fund uses a
proprietary model to determine asset allocations.

The Fund commenced operations on April 4, 2005.

WHAT MARKET CONDITIONS AFFECTED THE FUND'S PERFORMANCE DURING THE PERIOD FROM
APRIL 4 THROUGH APRIL 30, 2005?

Equity markets provided weak performance during the last four weeks of April
2005. Although all capitalization levels provided negative returns, large-cap
stocks declined the least, followed by mid-caps then small-caps. Bond markets
generally rose during the same four-week period. Fluctuating oil prices,
uncertainty in world markets, and continuing tensions in the Middle East all
contributed to equity-market weakness.

HOW DID THE UNDERLYING FUNDS PERFORM DURING THE FOUR-WEEK REPORTING PERIOD?

All of the underlying Funds except MainStay MAP Fund underperformed their
respective benchmarks during the last four weeks of April 2005. All of the
Fund's underlying fixed-income Funds had positive returns for the four-week
reporting period. The Fund had greater allocations to some of the stronger-
performing underlying equity Funds, which also helped the Fund's performance in
a difficult since-inception period.

AT THE END OF THE REPORTING PERIOD, HOW WAS THE FUND ALLOCATED AMONG THE
UNDERLYING FUNDS?

Since inception, the Fund has invested in 11 underlying Funds. Because of the
short reporting period, allocations have not been shifted, except by market
movements.

As of April 30, 2005, all allocations of invested assets were close to the
Fund's targets. On that date, the Fund held its greatest single allocation
(38.21%) in MainStay Indexed Bond Fund. At the same time, the Fund allocated
8.00% of its invested assets to MainStay Floating Rate Fund, 7.93% to MainStay
High Yield Corporate Bond Fund, and 6.03% to MainStay Intermediate Term Bond
Fund.

Among underlying equity Funds, the Fund's greatest allocation (20.99%) was to
MainStay Common Stock Fund. The Fund allocated 6.00% of its assets to MainStay
Large Cap Growth Fund, 4.95% to MainStay International Equity Fund, 2.98% to
MainStay All Cap Growth Fund, 1.99% to MainStay MAP Fund, 1.94% to MainStay
Small Cap Opportunity Fund, and 0.98% to MainStay Small Cap Value Fund.

LOOKING AHEAD, WHAT DO YOU SEE FOR THE FUND?

While a variety of factors could influence the markets, we will continue to rely
on our proprietary model to assess overall target allocations and determine
which specific Funds may provide the greatest potential for the Fund. Wherever
the markets may move, we will continue to invest in a variety of underlying
Funds using the allocation targets and constraints set forth in the prospectus.

THE DISCLOSURE AND FOOTNOTES ON THE FOLLOWING PAGE ARE AN INTEGRAL PART OF THE
PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS AND SHOULD BE CAREFULLY READ IN
CONJUNCTION WITH IT.

                                                   www.mainstayfunds.com     239


The Fund's performance depends on the advisor's skill in determining the
asset-class allocations, the mix of underlying MainStay Funds, as well as the
performance of those underlying Funds. The underlying Funds' performance may be
lower than the performance of the asset class the underlying Funds were selected
to represent. The Fund is indirectly subject to the investment risks of each
underlying Fund held. Principal risks of the underlying Funds are described
below.

MainStay Conservative Allocation Fund is a "fund of funds" that invests in other
MainStay Funds. The cost of investing in the Fund may be higher than the cost of
investing in a mutual fund that invests directly in individual stocks and bonds.
By investing in the Fund, clients will indirectly bear fees and expenses charged
by the underlying Funds in which the Fund invests in addition to the Fund's
direct fees and expenses. In addition, the use of a fund-of-funds structure
could affect the timing, amount, and character of distributions to the client
and may increase taxes payable by the client.

The Fund may invest more than 25% of its assets in one underlying Fund which may
significantly affect the net asset value of the Fund.

- - Stocks and bonds can decline because of adverse issuer, market, regulatory, or
  economic developments. High-yield securities carry higher risks, and some of
  the underlying Funds' investments have speculative characteristics and present
  a greater risk of loss than higher-quality debt securities. These securities
  can also be subject to greater price volatility.

- - There are additional risks associated with investing in small-cap securities.
  Stocks of small companies may be subject to higher price volatility,
  significantly lower trading volume, and greater spreads between bid and ask
  prices than stocks of larger companies. Furthermore, small-cap companies may
  be more vulnerable to adverse business or market developments and may have
  more limited product lines than larger-capitalization stocks.

- - There are additional risks associated with investing in mid-cap securities.
  Stocks of mid-cap companies may be more volatile and less liquid than the
  securities of larger companies.

- - Foreign securities may be subject to greater risk than U.S. investments,
  including currency fluctuations, less-liquid trading markets, greater price
  volatility, political and economic instability, less publicly available
  information, and changes in tax or currency laws or monetary policy.

- - When interest rates rise, the prices of fixed-income securities in the
  underlying Funds' portfolios will generally fall. On the other hand, when
  interest rates fall, the prices of fixed-income securities in the underlying
  Funds' portfolios will generally rise.

- - Underlying floating-rate Funds are generally considered to have speculative
  characteristics. These Funds may involve risk of default on principal and
  interest and risks associated with collateral impairment, nondiversification,
  borrower industry concentration, and limited liquidity.

- - AN INVESTMENT IN A MONEY-MARKET FUND IS NOT INSURED OR GUARANTEED BY THE FDIC
  OR ANY OTHER GOVERNMENT AGENCY. ALTHOUGH THE UNDERLYING FUND SEEKS TO MAINTAIN
  A VALUE OF $1.00 PER SHARE, IT IS POSSIBLE TO LOSE MONEY.

Before making an investment in the Fund, you should consider all the risks
associated with it.

Performance tables do not reflect the deduction of taxes that a shareholder
would pay on distributions or Fund-share redemptions. Total returns reflect
change in share price, reinvestment of dividend and capital-gain distributions,
and maximum applicable sales charges explained in this paragraph. Class A shares
are sold with a maximum initial sales charge of 5.5% and an annual 12b-1 fee of
..25%. Class B shares are sold with no initial sales charge, are subject to a
contingent deferred sales charge (CDSC) of up to 5% 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% 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 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. The Manager has contractually agreed to limit the Fund's total fund
operating expenses through October 31, 2005. There is no guarantee that the
contractual waiver will continue after that date.

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY GROWTH ALLOCATION FUND

The example below is intended to describe the fees and expenses borne by
shareholders during the reporting period 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, if applicable, exchange fees, and sales
charges (loads) on purchase payments, and (2) ongoing costs, including
management fees, distribution and/or service (12b-1) fees, and other Fund
expenses. 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 November 1, 2004, to April 30, 2005.

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 over the period. 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 balance or
expenses you paid for the period. You may use this information to compare the
ongoing costs of investing in the Fund and 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 Tony Elavia and Devon McCormick, CFA,
of New York Life Investment Management LLC

CAN YOU BRIEFLY DESCRIBE THE FUND'S INVESTMENT APPROACH?

MainStay Growth Allocation Fund seeks to achieve its investment objective by
investing in a variety of other MainStay Funds, known as underlying Funds. A
two-stage asset-allocation process includes deciding how much to invest in broad
asset classes and how much to invest in specific underlying Funds. Normally the
Fund invests substantially all of its assets in underlying equity Funds
(normally within a range of 85% to 100%). For cash management purposes, the Fund
may hold a portion of its assets directly in U.S. government securities,
money-market funds, cash, or cash equivalents. The underlying Funds use a broad
array of investment styles, may invest in a wide variety of equity securities,
and carry different types and degrees of risk. Some underlying Funds may invest
in foreign securities. The Fund uses a proprietary model to determine asset
allocations.

The Fund commenced operations on April 4, 2005.

WHAT MARKET CONDITIONS AFFECTED THE FUND'S PERFORMANCE DURING THE PERIOD FROM
APRIL 4 THROUGH APRIL 30, 2005?

Equity markets provided weak performance during the last four weeks of April
2005. Although all capitalization levels provided negative returns, large-cap
stocks declined the least, followed by mid-caps then small-caps. Fluctuating oil
prices, uncertainty in world markets, and continuing tensions in the Middle East
all contributed to equity-market weakness.

HOW DID THE UNDERLYING FUNDS PERFORM DURING THE FOUR-WEEK REPORTING PERIOD?

All of the underlying Funds except MainStay MAP Fund underperformed their
respective benchmarks during the last four weeks of April 2005. The Fund had
greater allocations to some of the stronger-performing underlying equity Funds,
which helped the Fund's performance in a difficult since-inception period.

AT THE END OF THE REPORTING PERIOD, HOW WAS THE FUND ALLOCATED AMONG THE
UNDERLYING FUNDS?

Since inception, the Fund has invested in seven underlying Funds. Because of the
short reporting period, allocations have not been shifted, except by market
movements.

As of April 30, 2005, all allocations of invested assets were close to the
Fund's targets. On that date, the Fund held its greatest single allocation
(38.17%) in MainStay Common Stock Fund. At the same time, the Fund allocated
21.89% of its invested assets to MainStay International Equity Fund, 19.13% to
MainStay Large Cap Growth Fund, 5.99% to MainStay MAP Fund, 6.00% to MainStay
All Cap Growth Fund, 4.88% to MainStay Small Cap Opportunity Fund, and 3.94% to
MainStay Small Cap Value Fund. The Fund had no allocation to underlying
fixed-income Funds.

LOOKING AHEAD, WHAT DO YOU SEE FOR THE FUND?

While a variety of factors could influence the markets, we will continue to rely
on our proprietary model to assess overall target allocations and determine
which specific Funds may provide the greatest potential for the Fund. Wherever
the markets may move, we will continue to invest in a variety of underlying
Funds using the allocation targets and constraints set forth in the prospectus.

The opinions expressed are those of the portfolio managers as of the date of
this report and are subject to change. There is no guarantee that any forecasts
made will come to pass. This material does not constitute investment advice and
is not intended as an endorsement of any specific investment.

The Fund's performance depends on the advisor's skill in determining the
asset-class allocations, the mix of underlying MainStay Funds, as well as the
performance of those underlying Funds. The underlying Funds' performance may be
lower than the performance of the asset class the underlying Funds were selected
to represent. The Fund is indirectly subject to the investment risks of each
underlying Fund held. Principal risks of the underlying Funds are described on
this page and the following page.

MainStay Growth Allocation Fund is a "fund of funds" that invests in other
MainStay Funds. The cost of investing in the Fund may be higher than the cost of
investing in a mutual fund that invests directly in individual stocks and bonds.
By investing in the Fund, clients will indirectly bear fees and expenses charged
by the underlying Funds in which the Fund invests in addition to the Fund's
direct fees and expenses. In addition, the use of a fund-of-funds structure
could affect the timing, amount, and character of distributions to the client
and may increase taxes payable by the client.

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS AND SHOULD BE CAREFULLY READ IN
CONJUNCTION WITH IT.

 250   MainStay Growth Allocation Fund


The Fund may invest more than 25% of its assets in one underlying Fund which may
significantly affect the net asset value of the Fund.

- - Stocks and bonds can decline because of adverse issuer, market, regulatory, or
  economic developments. High-yield securities carry higher risks, and some of
  the underlying Funds' investments have speculative characteristics and present
  a greater risk of loss than higher-quality debt securities. These securities
  can also be subject to greater price volatility.

- - There are additional risks associated with investing in small-cap securities.
  Stocks of small companies may be subject to higher price volatility,
  significantly lower trading volume, and greater spreads between bid and ask
  prices than stocks of larger companies. Furthermore, small-cap companies may
  be more vulnerable to adverse business or market developments and may have
  more limited product lines than larger-capitalization stocks.

- - There are additional risks associated with investing in mid-cap securities.
  Stocks of mid-cap companies may be more volatile and less liquid than the
  securities of larger companies.

- - Foreign securities may be subject to greater risks than U.S. investments,
  including currency fluctuations, less-liquid trading markets, greater price
  volatility, political and economic instability, less publicly available
  information, and changes in tax or currency laws or monetary policy.

- - AN INVESTMENT IN A MONEY-MARKET FUND IS NOT INSURED OR GUARANTEED BY THE FDIC
  OR ANY OTHER GOVERNMENT AGENCY. ALTHOUGH THE UNDERLYING FUND SEEKS TO MAINTAIN
  A VALUE OF $1.00 PER SHARE, IT IS POSSIBLE TO LOSE MONEY.

Before making an investment in the Fund, you should consider all the risks
associated with it.

Performance tables do not reflect the deduction of taxes that a shareholder
would pay on distributions or Fund-share redemptions. Total returns reflect
change in share price, reinvestment of dividend and capital-gain distributions,
and maximum applicable sales charges explained in this paragraph. Class A shares
are sold with a maximum initial sales charge of 5.5% and an annual 12b-1 fee of
..25%. Class B shares are sold with no initial sales charge, are subject to a
contingent deferred sales charge (CDSC) of up to 5% 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% 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 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. The Manager has contractually agreed to limit the Fund's total fund
operating expenses through October 31, 2005. There is no guarantee that the
contractual waiver will continue after that date.

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY MODERATE ALLOCATION FUND

The example below is intended to describe the fees and expenses borne by
shareholders during the reporting period 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, if applicable, exchange fees, and sales
charges (loads) on purchase payments, and (2) ongoing costs, including
management fees, distribution and/or service (12b-1) fees, and other Fund
expenses. 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 November 1, 2004, to April 30, 2005.

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 over the period. 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 balance or
expenses you paid for the period. You may use this information to compare the
ongoing costs of investing in the Fund and 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.

 260   MainStay Moderate Allocation Fund


PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

Questions answered by portfolio managers Tony Elavia and Devon McCormick, CFA,
of New York Life Investment Management LLC

CAN YOU BRIEFLY DESCRIBE THE FUND'S INVESTMENT APPROACH?

MainStay Moderate Allocation Fund seeks to achieve its investment objective by
investing in a variety of other MainStay Funds, known as underlying Funds. A
two-stage asset-allocation process includes deciding how much to invest in broad
asset classes and how much to invest in specific underlying Funds. Normally the
Fund invests approximately 60% (within a range of 50% to 70%) of its assets in
underlying equity Funds and approximately 40% (within a range of 30% to 50%) of
its assets in underlying fixed-income Funds. The Fund's fixed-income component
may include a money-market component. For cash management purposes, the Fund may
hold a portion of its assets directly in U.S. government securities,
money-market funds, cash, or cash equivalents. The underlying Funds use a broad
array of investment styles; may invest in a wide variety of equity securities,
fixed-income securities, or both; and carry different types and degrees of risk.
Some underlying Funds may invest in foreign securities. The Fund uses a
proprietary model to determine asset allocations.

The Fund commenced operations on April 4, 2005.

WHAT MARKET CONDITIONS AFFECTED THE FUND'S PERFORMANCE DURING THE PERIOD FROM
APRIL 4 THROUGH APRIL 30, 2005?

Equity markets provided weak performance during the last four weeks of April
2005. Although all capitalization levels provided negative returns, large-cap
stocks declined the least, followed by mid-caps then small-caps. Bond markets
generally rose during the same four-week period. Fluctuating oil prices,
uncertainty in world markets, and continuing tensions in the Middle East all
contributed to equity-market weakness.

HOW DID THE UNDERLYING FUNDS PERFORM DURING THE FOUR-WEEK REPORTING PERIOD?

All of the underlying Funds except MainStay MAP Fund underperformed their
respective benchmarks during the last four weeks of April 2005. All of the
Fund's underlying fixed-income Funds had positive returns for the four-week
reporting period. The Fund had greater allocations to some of the stronger-
performing underlying equity Funds, which also helped the Fund's performance in
a difficult since-inception period.

AT THE END OF THE REPORTING PERIOD, HOW WAS THE FUND ALLOCATED AMONG THE
UNDERLYING FUNDS?

Since inception, the Fund has invested in 11 underlying Funds. Because of the
short reporting period, allocations have not been shifted, except by market
movements.

As of April 30, 2005, all allocations of invested assets were close to the
Fund's targets. On that date, the Fund held its greatest single allocation
(27.24%) in MainStay Indexed Bond Fund. At the same time, the Fund allocated
5.02% of its invested assets to MainStay Floating Rate Fund, 4.97% to MainStay
High Yield Corporate Bond Fund, and 3.02% to MainStay Intermediate Term Bond
Fund.

Among underlying equity Funds, the Fund's greatest allocation (25.99%) was to
MainStay Common Stock Fund. The Fund allocated 11.89% of its invested assets to
MainStay International Equity Fund, 9.03% to MainStay Large Cap Growth Fund,
3.99% to MainStay MAP Fund, 3.98% to MainStay All Cap Growth Fund, 3.89% to
MainStay Small Cap Opportunity Fund, and 0.98% to MainStay Small Cap Value Fund.

LOOKING AHEAD, WHAT DO YOU SEE FOR THE FUND?

While a variety of factors could influence the markets, we will continue to rely
on our proprietary model to assess overall target allocations and determine
which specific Funds may provide the greatest potential for the Fund. Wherever
the markets may move, we will continue to invest in a variety of underlying
Funds using the allocation targets and constraints set forth in the prospectus.


The opinions expressed are those of the portfolio managers as of the date of
this report and are subject to change. There is no guarantee that any forecasts
made will come to pass. This material does not constitute investment advice and
is not intended as an endorsement of any specific investment.

The Fund's performance depends on the advisor's skill in determining the
asset-class allocations, the mix of underlying MainStay Funds, as well as the
performance of those underlying Funds. The underlying Funds' performance may be
lower than the performance of the asset class the underlying Funds were selected
to represent. The Fund is indirectly subject to the investment risks of each
underlying Fund held. Principal risks of the underlying Funds are described on
the following page.

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS AND SHOULD BE CAREFULLY READ IN
CONJUNCTION WITH IT.

MainStay Moderate Allocation Fund is a "fund of funds" that invests in other
MainStay Funds. The cost of investing in the Fund may be higher than the cost of
investing in a mutual fund that invests directly in individual stocks and bonds.
By investing in the Fund, clients will indirectly bear fees and expenses charged
by the underlying Funds in which the Fund invests in addition to the Fund's
direct fees and expenses. In addition, the use of a fund-of-funds structure
could affect the timing, amount, and character of distributions to the client
and may increase taxes payable by the client.

The Fund may invest more than 25% of its assets in one underlying Fund which may
significantly affect the net asset value of the Fund.

- - Stocks and bonds can decline because of adverse issuer, market, regulatory, or
  economic developments. High-yield securities carry higher risks, and some of
  the underlying Funds' investments have speculative characteristics and present
  a greater risk of loss than higher-quality debt securities. These securities
  can also be subject to greater price volatility.

- - There are additional risks associated with investing in small-cap securities.
  Stocks of small companies may be subject to higher price volatility,
  significantly lower trading volume, and greater spreads between bid and ask
  prices than stocks of larger companies. Furthermore, small-cap companies may
  be more vulnerable to adverse business or market developments and may have
  more limited product lines than larger-capitalization stocks.

- - There are additional risks associated with investing in mid-cap securities.
  Stocks of mid-cap companies may be more volatile and less liquid than the
  securities of larger companies.

- - Foreign securities may be subject to greater risks than U.S. investments,
  including currency fluctuations, less-liquid trading markets, greater price
  volatility, political and economic instability, less publicly available
  information, and changes in tax or currency laws or monetary policy.

- - When interest rates rise, the prices of fixed-income securities in the
  underlying Funds' portfolios will generally fall. Conversely, when interest
  rates fall, the prices of fixed-income securities in the underlying Funds'
  portfolios will generally rise.

- - Underlying floating-rate Funds are generally considered to have speculative
  characteristics. These Funds may involve risk of default on principal and
  interest and risks associated with collateral impairment, nondiversification,
  borrower industry concentration, and limited liquidity.

- - AN INVESTMENT IN A MONEY-MARKET FUND IS NOT INSURED OR GUARANTEED BY THE FDIC
  OR ANY OTHER GOVERNMENT AGENCY. ALTHOUGH THE UNDERLYING FUND SEEKS TO MAINTAIN
  A VALUE OF $1.00 PER SHARE, IT IS POSSIBLE TO LOSE MONEY.

Before making an investment in the Fund, you should consider all the risks
associated with it.

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY MODERATE GROWTH ALLOCATION
FUND

The example below is intended to describe the fees and expenses borne by
shareholders during the reporting period 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, if applicable, exchange fees, and sales
charges (loads) on purchase payments, and (2) ongoing costs, including
management fees, distribution and/or service (12b-1) fees, and other Fund
expenses. 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 November 1, 2004, to April 30, 2005.

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 over the period. 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 balance or
expenses you paid for the period. You may use this information to compare the
ongoing costs of investing in the Fund and 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 Tony Elavia and Devon McCormick, CFA,
of New York Life Investment Management LLC

CAN YOU BRIEFLY DESCRIBE THE FUND'S INVESTMENT APPROACH?

MainStay Moderate Growth Allocation Fund seeks to achieve its investment
objective by investing in a variety of other MainStay Funds, known as underlying
Funds. A two-stage asset-allocation process includes deciding how much to invest
in broad asset classes and how much to invest in specific underlying Funds.
Normally the Fund invests approximately 80% (within a range of 70% to 90%) of
its assets in underlying equity Funds and approximately 20% (within a range of
10% to 30%) of its assets in underlying fixed-income Funds. The Fund's fixed-
income component may include a money-market component. For cash management
purposes, the Fund may hold a portion of its assets directly in U.S. government
securities, money-market funds, cash, or cash equivalents. The underlying Funds
use a broad array of investment styles; may invest in a wide variety of equity
securities, fixed-income securities, or both; and carry different types and
degrees of risk. Some underlying Funds may invest in foreign securities. The
Fund uses a proprietary model to determine asset allocations.

The Fund commenced operations on April 4, 2005.

WHAT MARKET CONDITIONS AFFECTED THE FUND'S PERFORMANCE DURING THE PERIOD FROM
APRIL 4 THROUGH APRIL 30, 2005?

Equity markets provided weak performance during the last four weeks of April
2005. Although all capitalization levels provided negative returns, large-cap
stocks declined the least, followed by mid-caps then small-caps. Bond markets
generally rose during the same four-week period. Fluctuating oil prices,
uncertainty in world markets, and continuing tensions in the Middle East all
contributed to equity-market weakness.

HOW DID THE UNDERLYING FUNDS PERFORM DURING THE FOUR-WEEK REPORTING PERIOD?

All of the underlying Funds except MainStay MAP Fund underperformed their
respective benchmarks during the last four weeks of April 2005. All of the
Fund's underlying fixed-income Funds had positive returns for the four-week
reporting period. The Fund had greater allocations to some of the stronger-
performing underlying equity Funds, which also helped the Fund's performance in
a difficult since-inception period.

AT THE END OF THE REPORTING PERIOD, HOW WAS THE FUND ALLOCATED AMONG THE
UNDERLYING FUNDS?

Since inception, the Fund has invested in 10 underlying Funds. Because of the
short reporting period, allocations have not been shifted, except by market
movements.

As of April 30, 2005, all allocations of invested assets were close to the
Fund's targets. On that date, the Fund held its greatest single allocation
(27.09%) in MainStay Common Stock Fund. At the same time, the Fund allocated
17.10% of its invested assets to MainStay Large Cap Growth Fund, 16.88% to
MainStay International Equity Fund, 6.00% to MainStay All Cap Growth Fund, 4.99%
to MainStay MAP Fund, 4.88% to MainStay Small Cap Opportunity Fund, and 2.96% to
MainStay Small Cap Value Fund.

Among underlying fixed-income Funds, the Fund's greatest allocation (10.10%) was
to MainStay Indexed Bond Fund. The Fund allocated 5.02% of its invested assets
to MainStay Floating Rate Fund, and 4.98% to MainStay High Yield Corporate Bond
Fund.

LOOKING AHEAD, WHAT DO YOU SEE FOR THE FUND?

While a variety of factors could influence the markets, we will continue to rely
on our proprietary model to assess overall target allocations and determine
which specific Funds may provide the greatest potential for the Fund. Wherever
the markets may move, we will continue to invest in a variety of underlying
Funds using the allocation targets and constraints set forth in the prospectus.


The opinions expressed are those of the portfolio managers as of the date of
this report and are subject to change. There is no guarantee that any forecasts
made will come to pass. This material does not constitute investment advice and
is not intended as an endorsement of any specific investment.

The Fund's performance depends on the advisor's skill in determining the
asset-class allocations, the mix of underlying MainStay Funds, as well as the
performance of those underlying Funds. The underlying Funds' performance may be
lower than the performance of the asset class the underlying Funds were selected
to represent. The Fund is indirectly subject to the investment risks of each
underlying Fund held. Principal risks of the underlying Funds are described on
the following page.

 272   MainStay Moderate Growth Allocation Fund




MainStay Moderate Growth Allocation Fund is a "fund-of-funds" that invests in
other MainStay Funds. The cost of investing in the Fund may be higher than the
cost of investing in a mutual fund that invests directly in individual stocks
and bonds. By investing in the Fund, clients will indirectly bear fees and
expenses charged by the underlying Funds in which the Fund invests in addition
to the Fund's direct fees and expenses. In addition, the use of a fund-of-funds
structure could affect the timing, amount, and character of distributions to the
client and may increase taxes payable by the client.

The Fund may invest more than 25% of its assets in one underlying Fund which may
significantly affect the net asset value of the Fund.

- - Stocks and bonds can decline because of adverse issuer, market, regulatory, or
  economic developments. High-yield securities carry higher risks, and some of
  the underlying Funds' investments have speculative characteristics and present
  a greater risk of loss than higher-quality debt securities. These securities
  can also be subject to greater price volatility.

- - There are additional risks associated with investing in small-cap securities.
  Stocks of small companies may be subject to higher price volatility,
  significantly lower trading volume, and greater spreads between bid and ask
  prices than stocks of larger companies. Furthermore, small-cap companies may
  be more vulnerable to adverse business or market developments and may have
  more limited product lines than larger-capitalization stocks.

- - There are additional risks associated with investing in mid-cap securities.
  Stocks of mid-cap companies may be more volatile and less liquid than the
  securities of larger companies.

- - Foreign securities may be subject to greater risks than U.S. investments,
  including currency fluctuations, less-liquid trading markets, greater price
  volatility, political and economic instability, less publicly available
  information, and changes in tax or currency laws or monetary policy.

- - When interest rates rise, the prices of fixed-income securities in the
  underlying Funds' portfolios will generally fall. Conversely, when interest
  rates fall, the prices of fixed-income securities in the underlying Funds'
  portfolios will generally rise.

- - Underlying floating-rate Funds are generally considered to have speculative
  characteristics. These Funds may involve risk of default on principal and
  interest and risks associated with collateral impairment, nondiversification,
  borrower industry concentration, and limited liquidity.

- - AN INVESTMENT IN A MONEY-MARKET FUND IS NOT INSURED OR GUARANTEED BY THE FDIC
  OR ANY OTHER GOVERNMENT AGENCY. ALTHOUGH THE UNDERLYING FUND SEEKS TO MAINTAIN
  A VALUE OF $1.00 PER SHARE, IT IS POSSIBLE TO LOSE MONEY.

Before making an investment in the Fund, you should consider all the risks
associated with it.

NOTES TO FINANCIAL STATEMENTS UNAUDITED (CONTINUED)

The investment objectives for each of the Funds are as follows:

The ALL CAP GROWTH FUND seeks long-term growth of capital. Dividend income, if
any, is a consideration incidental to the Fund's objective of growth of capital.

The ALL CAP VALUE FUND seeks maximum long-term total return from a combination
of capital growth and income.

The MID CAP OPPORTUNITY FUND seeks high total return.

The S&P 500 INDEX FUND seeks 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.

The SMALL CAP OPPORTUNITY FUND seeks high total return.

The CASH RESERVES FUND seeks a high level of current income while preserving
capital and maintaining liquidity.

The FLOATING RATE FUND seeks to provide high current income.

The INDEXED BOND FUND seeks to provide investment results that correspond to the
total return performance of fixed income securities in the aggregate, as
represented by the Citigroup Broad Investment Grade ("BIG") Bond Index.

The INTERMEDIATE TERM BOND FUND seeks to maximize total return, consistent with
liquidity, low risk to principal and investment in debt securities.

The SHORT TERM BOND FUND seeks to maximize total return, consistent with
liquidity, preservation of capital and investment in short-term debt securities.

The ASSET MANAGER FUND seeks to maximize total return, consistent with certain
percentage constraints on amounts allocated to each asset class, from a
combination of common stocks, fixed income securities, and money market
investments.

The BALANCED FUND seeks high total return.

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 ability of issuers of debt securities held by the Funds to meet their
obligations may be affected by economic developments in a specific industry or
region.

There are certain risks involved in investing in foreign securities that are in
addition to the usual risks inherent in domestic instruments. These risks
include those resulting from future adverse political and economic developments
and possible imposition of currency exchange blockages or other foreign
governmental laws or restrictions. Foreign securities may also be less liquid
and more volatile than U.S. securities. There may also be difficulty in invoking
legal protections across borders. In addition, investment in emerging market
countries presents risks in greater degree than those presented by investment in
foreign issuers in countries with developed securities markets and more advanced
regulatory systems.

NOTE 2 -- SIGNIFICANT ACCOUNTING POLICIES:

The Funds prepare their financial statements in accordance with U.S. generally
accepted accounting principles 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 trading on the New York Stock Exchange
(generally 4:00 p.m. Eastern time) on the valuation date; such securities not
traded on the valuation date are valued at the mean of the latest quoted bid and
asked prices. Prices are taken from the primary market in which each security
trades. Debt securities are valued at prices supplied by a pricing agent or
brokers selected by the Fund's Manager, whose prices reflect broker/dealer
supplied valuations and/or electronic data processing techniques if such prices
are deemed by the Funds' Manager to be representative of market values at the
regular close of business of the Exchange. Loans are valued at the average of
bid quotations obtained from a pricing service. Options and futures contracts
are valued at the last sale price on the market where such options or futures
contracts are principally traded. Temporary cash investments acquired with over
60 days 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 are valued at amortized cost, which
approximates market value. Pursuant to Rule 2a-7 of the Investment Company Act,
portfolio securities of Cash Reserves Fund are valued at their amortized cost,
which approximates market value in order to maintain a net asset value of $1.00
per share, although there is no assurance that it will be able to do so.
Securities for which market quotations are not readily available are valued by
methods deemed by the Board of Directors and/or the Board of Trustees to
represent fair value. Reasons for which securities may be valued in this manner
include, but are not limited to, trading for a security has been halted or
suspended, a security has been de-listed from a national exchange, or trading on
a security's primary market is temporarily closed at a time when under normal
conditions it would be open. As of April 30, 2005, the Balanced Fund held
securities with a value of $17,162 that were valued in such manner. Foreign
currency forward contracts are valued at their fair market values determined

 280   MainStay Funds


on the basis of the mean between the last bid and asked prices based on dealer
or exchange quotations.

Certain events, which may occur in the U.S. or abroad, and which may include but
are not limited to natural disasters, armed conflicts, governmental actions or
other developments not tied directly to the securities markets, may occur
between the time that foreign markets close, on which securities held by the
Funds principally trade, and the time at which the Funds' NAVs are calculated.
Should the Funds conclude that such events may have affected the fair value of
securities since the last price reported on the local foreign market, the Funds
may, pursuant to procedures adopted by the Company's Board of Directors and/or
the Trust's Board of Trustees, adjust the value of the local price to reflect
the impact on the price of such securities as a result of such events.

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

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

(C) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are
recorded on the ex-dividend date. For the Cash Reserves and Floating Rate Funds,
dividends are declared daily and paid monthly and capital gain distributions, if
any, are declared and paid annually. For the Indexed Bond, Intermediate Term
Bond and Short Term Bond Funds, income dividends are declared and paid monthly
and capital gain distributions, if any, are declared and paid annually. For the
Balanced Fund, income dividends are declared and paid quarterly and capital gain
distributions, if any, are declared and paid annually. Each of the other Funds
intends to declare and pay, as a dividend, substantially all of its net
investment income at least once a year and net realized capital gains no more
than once a year. Income dividends and capital gain distributions are determined
in accordance with federal income tax regulations, which may differ from
generally accepted accounting principles. These "book/tax differences" are
either considered temporary or permanent in nature. To the extent these
differences are permanent in nature, such amounts are reclassified within the
capital accounts based on their federal tax basis treatment; temporary
differences do not require reclassification.

(D) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  The 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.
Discounts and premiums on securities, other than short-term securities,
purchased for all Funds are accreted and amortized, respectively, on the
constant yield 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 securities are accreted and amortized, respectively, on
the straight line method.

Investment income and realized and unrealized gains and losses on investments of
a Fund are allocated to separate classes of shares 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 with respect to the Funds 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 expenses incurred under the Shareholder Services
Plans and the Distribution Plans) are allocated to separate classes of shares
based upon their relative net assets on the date the expenses are incurred. The
expenses borne by each Fund, including those of related parties to the Funds,
are shown on each Fund's Statement of Operations.

New York Life Investment Management LLC ("NYLIM") had directed certain portfolio
trades to brokers who agreed to pay a portion of the expenses for the Mid Cap
Opportunity, Small Cap Opportunity and Balanced Funds. This arrangement ended on
April 8, 2004. For the year ended October 31, 2004, each of these Fund's
expenses (transfer agent fees and expenses) were reduced by $3,310, $42,247 and
$39,765, respectively, under these arrangements. The credit balances remaining
as of April 8, 2004 were $2,877, $63,486 and $772 for the Mid Cap Opportunity,
Small Cap Opportunity and Balanced Funds, respectively, and are included on the
Statement of Operations under net realized and unrealized gain (loss) on
investments.

(F) USE OF ESTIMATES.  The preparation of financial statements in accordance
with U.S. generally accepted accounting principles requires management to make
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.  Certain Funds may write covered call and put
options on their portfolio securities or foreign currencies. Premiums are
received and are recorded as liabilities. The liabilities are subsequently
adjusted to reflect the current value of the options written. Premiums received
from writing options which expire are treated as realized gains. Premiums
received from writing options which are exercised or are canceled in closing
purchase transactions are added to the proceeds or netted against the amount
paid on the

                                                   www.mainstayfunds.com     281

NOTES TO FINANCIAL STATEMENTS UNAUDITED (CONTINUED)

transaction to determine the realized gain or loss. By writing a covered call
option, in exchange for the premium, a Fund foregoes the opportunity for capital
appreciation above the exercise price should the market price of the underlying
security or foreign currency increase. By writing a covered put option, a 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, in a segregated account with its custodian. When writing a
covered call option, the Funds, in return for the premium on the option, give up
the opportunity to profit from a price increase in the underlying securities
above the exercise price, but, as long as the obligation as a writer continues,
have retained the risk of loss should the price of the underlying security
decline. After writing a put option, a Fund may incur a loss 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.

Certain Funds may purchase call and put options on their portfolio securities or
foreign currencies. A Fund may purchase call options to protect against an
increase in the price of the security or foreign currency it anticipates
purchasing. A 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. A 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 exposure to loss for any
purchased option is limited to the premium initially paid for the option (see
Note 7).

(H) LOANS AND COMMITMENTS.  The Floating Rate Fund makes loans and loan
assignments ("loans"), which 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 which 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 London InterBank Offered Rate (LIBOR).

The loans made by the Fund are generally readily marketable, but may be subject
to some restrictions on resale. The Fund may be contractually obligated to
receive approval from the agent bank and/or borrower prior to sale.

The Fund assumes the credit risk of the borrower. In the event that the borrower
becomes 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.

The Fund also makes subordinated loans. The primary risk arising from such loans
is the potential loss in the event of default by the borrower. As of April 30,
2005, the Fund held 1.92% of its net assets in subordinated loans.

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 recorded in
memorandum accounts (see Note 6).

(I) 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 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 Intermediate Term Bond Fund may enter into
foreign currency forward contracts primarily to hedge its foreign currency
denominated investments and receivables and payables against adverse movements
in future foreign exchange rates or to try to enhance the Fund's 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 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. The
unrealized appreciation on forward contracts reflects the Fund's exposure at
period end to credit loss in the event of a counterparty's failure to perform
its obligations (see Note 7).

(J) FUTURES CONTRACTS.  A futures contract is an agreement to purchase or sell a
specified quantity of an

 282   MainStay Funds


underlying instrument at a specified future date and price, or to make or
receive a cash payment based on the value of a securities index, foreign
currency or interest rate. 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. Futures
contracts are used for hedging purposes or to seek to enhance returns (see Note
5).

(K) REPURCHASE AGREEMENTS.  The Fund's custodian takes possession of the
collateral pledged for investments in 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.


(L) FOREIGN CURRENCY TRANSACTIONS.  The books and records of the Funds are kept
in U.S. dollars. Foreign currency amounts are translated into U.S. dollars at
the mean between the buying and selling 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,

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


The assets and liabilities of each Fund are presented at the exchange rates and
market values at the end 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 recorded on
each Fund's books and the U.S. dollar equivalent amount actually received or
paid. Net currency gains or losses from valuing foreign currency denominated
assets and liabilities, other than investments, at valuation date exchange rates
are reflected in unrealized foreign exchange gains or losses.

(M) MORTGAGE DOLLAR ROLLS.  A mortgage dollar roll ("MDR") is a transaction in
which a Fund 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 a 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 Funds have 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. The Fund maintains a segregated
account with its custodian containing securities 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.

(N) SECURITIES LENDING.  Each Fund may lend its securities to broker-dealers and
financial institutions. The loans are collateralized by cash or securities at
least equal at all times to the market value of the securities loaned. 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 receives compensation for lending its securities in the form of fees or
it retains a portion of interest on the investment of any cash received as
collateral. The Fund also continues 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 (see Note 7).

(O) REDEMPTION FEE.  Effective May 3, 2004, the Floating Rate Fund imposed a
2.00% redemption fee on redemptions (including exchanges) of the Fund's shares
made within 60 days of their date of purchase. The redemption fee is designed to
offset brokerage commissions and other costs to the Fund associated with short-
term trading and is not assessed on shares acquired through the reinvestment of
dividends or distributions paid by the Fund. The redemption fee may not apply to
redemptions of certain benefit plan accounts such as 401(k) plans, section 529
qualified tuition plans, accounts held in omnibus accounts on the books of
certain financial intermediary firms, wrap program accounts, redemptions
effected through the systematic withdrawal/Exchange Plan or on redemptions of
shares held at the time of death or the initial determination of a permanent
disability of a shareholder. The redemption fees are included in the Statement
of Changes in Net Assets' shares redeemed amount and also as part of additional
paid-in capital on the Statement of Assets and Liabilities. The redemption fees
paid to the Fund for the six months ended April 30, 2005 totaled $43,747.

NOTE 5 -- FINANCIAL INVESTMENTS:
The S&P 500 Index Fund's, Indexed Bond Fund's and Asset Manager Fund's 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 are conducted through regulated exchanges which
minimize counterparty credit risks.

The S&P 500 Index Fund invests in stock index futures contracts to maintain cash
reserves while remaining fully invested, to facilitate trading, or to reduce
transaction costs. The Indexed Bond Fund invests in contracts for the future
delivery of debt securities in order to attempt to maintain cash reserves while
remaining fully invested, to facilitate trading, or to reduce transaction costs.
The Asset Manager Fund has entered into contracts for the future delivery of
debt securities and invests in stock index futures contracts to rebalance the
Fund's portfolio composition and risk profile to meet asset class constraints.

NOTES TO FINANCIAL STATEMENTS UNAUDITED (CONTINUED)

NOTE 13 -- OTHER MATTERS:

NYLIM and mutual funds that NYLIM advises have received requests for information
from various government authorities and regulatory bodies regarding market
timing, late trading, operations, fees, expenses, and other matters. NYLIM and
the funds it advises are cooperating fully in responding to these requests. To
date, substantially all of the costs associated with these and other regulatory
matters have been borne by NYLIM. Except as described below, neither NYLIM nor
the funds advised by it have any reason to believe that they have been targeted

The SEC Staff has raised concerns relating to a guarantee provided to
shareholders of the MainStay Equity Index Fund and the fees and expenses of that
Fund, as well as the related guarantee disclosure to Fund shareholders.
Discussions have been held with the SEC concerning a possible resolution of this
matter. There can be no assurance at this time as to the outcome of these
efforts. The MainStay Equity Index Fund is not a portfolio of the Eclipse Funds
Inc. or the Eclipse Funds.

BOARD CONSIDERATION AND APPROVAL OF MANAGEMENT AND SUBADVISORY AGREEMENTS

Section 15(c) of the Investment Company Act of 1940, as amended (the "1940 Act")
requires that each fund's board of directors or trustees, including a majority
of directors or trustees who are not "interested persons" of the fund, as
defined in the 1940 Act ("Independent Directors"), annually review and approve
the fund's investment advisory agreements.

At various meetings held between December 2004 and March 2005, the Board of
Directors/Trustees of the Funds (the "Board"), which is comprised solely of
Independent Directors, considered the approval or renewal of the Funds'
Management and Subadvisory Agreements, as appropriate (the "Agreements"). In
reaching its decision to approve the Agreements, the Board, which was advised by
independent legal counsel, considered the following factors and reached the
conclusions described below.

The Board examined the nature, extent and quality of the services that NYLIM
provides to the Funds. The Board evaluated NYLIM's experience in serving as
manager of the Funds, noting that NYLIM manages other mutual funds, serves a
variety of other investment advisory clients, including other pooled investment
vehicles, and has experience with overseeing MacKay Shields, its affiliate, as a
Subadviser to the All Cap Growth, All Cap Value, Intermediate Term Bond and
Short Term Bond Funds (collectively, the "Subadvised Funds"). The Board
considered the experience of senior personnel at NYLIM in providing investment
management and administrative services to the Funds as well as NYLIM's
reputation and financial condition. The Board noted recent staff additions in
NYLIM's senior management and other personnel responsible for mutual fund
operations, and resource enhancements supporting its delivery of services to the
Funds. The Board also considered NYLIM's performance in fulfilling its
responsibilities for overseeing the Funds' legal and compliance environment, and
overseeing MacKay Shields' compliance with the Funds' policies and investment
objectives, and in implementing Board directives as they relate to the Funds. In
addition, the Board noted that NYLIM also is responsible for paying the salaries
and expenses for each of the Funds' officers. The Board considered the scope and
quality of NYLIM's services provided to the Funds' shareholders (through its
affiliate NYLIM Service Company LLC), including the more extensive requirements
of New York Life agents and reputation as a high-quality provider of shareholder
services, which has been recognized by independent third-parties on multiple
occasions. The Board further considered NYLIM's track record and experience in
providing investment advisory services to those Funds that are not Subadvised
Funds. Based on these considerations, the Board concluded that each Fund is
likely to benefit from the nature, extent and quality of these services as a
result of NYLIM's experience, personnel, operations and resources.

The Board also examined the nature, extent and quality of the services that
MacKay Shields provides to the Subadvised Funds. It examined MacKay Shields'
track record and experience in providing investment advisory services to the
Subadvised Funds, the experience of senior personnel at MacKay Shields, and
MacKay Shields' overall legal and compliance environment. The Board also
reviewed MacKay Shields' willingness to invest in personnel and product
enhancements designed to benefit the Funds, including strengthened portfolio
management teams and additions to MacKay Shields' legal and compliance
departments. Based on these considerations, the Board concluded that each of the
Subadvised Funds is likely to benefit from the nature, extent and quality of
these services as a result of MacKay Shields' experience, personnel, operations
and resources.

In evaluating the investment performance for each of the Funds, the Board
considered information provided by NYLIM and MacKay Shields on each Fund's
performance track record as compared to its benchmark. The Board also considered
comparative data provided by Lipper, an independent third-party service
provider, on the performance of similar mutual funds managed by other investment
advisers.

In evaluating the Funds' management and subadvisory fees, the Board considered
information provided by NYLIM and MacKay Shields on the fees that NYLIM and
MacKay Shields charge to other investment advisory clients. The Board also
considered comparative data provided by Lipper, an independent third-party
service provider, on the fees and expense ratios charged by similar mutual funds
managed by other investment advisers. This comparative information assisted the
Board in evaluating the reasonableness of each Fund's management fees, discussed
in greater detail below, when compared to similar fees charged by NYLIM and
MacKay Shields to other investment advisory clients, and fees charged by other
investment advisers to mutual funds in each Fund's Lipper expense group.

The Board considered that, in addition to fees earned by NYLIM and MacKay
Shields for managing the Funds, NYLIM affiliates also earn revenues from serving
the Funds in various other capacities, including as transfer agent and
distributor. The Board reviewed information from NYLIM regarding the estimated
profitability realized by NYLIM and its affiliates due to their overall
relationship with the Funds, and with respect to each Fund individually. The
Board also reviewed information from NYLIM illustrating the expenses allocated
by NYLIM to each of the Funds. In

addition, the Board recognized the benefits to NYLIM and MacKay Shields from
legally permitted "soft dollar" arrangements by which brokers provide research
and other services to NYLIM and MacKay Shields in exchange for commissions paid
by the Funds with respect to trades on the Funds' portfolio securities.

In addition, the Board also considered the following factors for each Fund:

MAINSTAY ALL CAP GROWTH FUND

The Board noted that this Fund's performance track record appears to be below
that of its Lipper performance universe in recent years, but observed that,
based on information provided to the Board by NYLIM and MacKay Shields, the
Fund's performance has improved since it began investing in issuers representing
a broader range of market capitalizations. In addition, the Board considered the
investment MacKay Shields has made in recent personnel enhancements to this
Fund's portfolio management team. The Board concluded that it was appropriate to
continue monitoring the performance of this Fund as it develops a performance
track record in the all-capitalization universe and is impacted by the recent
enhancements to its portfolio management team.

The Board considered that this Fund's overall management fee appeared to be just
above its Lipper expense group median, but that the Fund's net total operating
expenses, after factoring the impact of expense limitations voluntarily
instituted by NYLIM, appear to be among the lowest in its Lipper expense group.
The Board also considered that, at the Board's request, NYLIM has now agreed to
obtain the Board's approval before raising or removing the expense limitation it
has placed on the Fund. Based on these considerations, the Board concluded that
the management fee was reasonable and compared favorably in relation to similar
portfolios.

The Board also considered whether the Fund's expense structure permitted
economies of scale to be shared with Fund investors. The Board reviewed
information from NYLIM and Lipper showing that the Fund's management fee remains
competitive within its Lipper expense group as the Fund's assets hypothetically
increase over time. Based on this information, the Board concluded that the
Fund's current expense structure reflects reasonable 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
continues to grow.

In addition, the Board considered information provided by NYLIM and MacKay
Shields on the costs associated with managing the Fund and the anticipated
profitability of the Fund to NYLIM and MacKay Shields. It considered NYLIM's and
MacKay Shields' investments in personnel, systems and equipment necessary to
manage the Fund, and the fact that NYLIM is responsible for paying MacKay
Shields' subadvisory fee. In light of these considerations, the Board concluded
that the anticipated profits to be realized by NYLIM and MacKay Shields were
reasonable.

MAINSTAY ALL CAP VALUE FUND

The Board noted that, in recent years, the Fund's performance appears to be
below the median of its Lipper performance universe. The Board considered
ongoing efforts by MacKay Shields, as described to the Board, to evaluate this
Fund's investment process. In addition, the Board noted the recent investment
MacKay Shields' has made in personnel enhancements to this Fund's portfolio
management team. The Board concluded that it would continue to actively monitor
this Fund's performance over the coming year, as MacKay Shields continues to
evaluate the Fund's investment strategies and processes, and the Fund is
impacted by the recent enhancements to its portfolio management team.

The Board also noted that, although this Fund's overall management fee appears
to be above its Lipper expense group median, the Fund's net management fee,
after factoring the impact of expense limitations voluntarily put in place by
NYLIM, appears to be at the lower end of its Lipper expense group. In addition,
the Fund's net total operating expenses also appear to be at the lower end of
its Lipper expense group. The Board considered that, at the Board's request,
NYLIM has now agreed to obtain the Board's approval before raising or removing
the expense limitation it has placed on the Fund. Based on these considerations,
the Board concluded that the management fee was reasonable and compared
favorably in relation to similar portfolios.

The Board also considered whether the Fund's expense structure permitted
economies of scale to be shared with Fund investors. The Board considered
information from NYLIM and Lipper showing that the Fund's management fee remains
within a reasonable range of the Lipper expense median as assets hypothetically
increase over time. Based on this information, the Board concluded that the
Fund's current 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
continues to grow.

In addition, the Board considered information provided by NYLIM and MacKay
Shields on the costs associated with managing the Fund and the anticipated
profitability of the Fund. It considered NYLIM's and MacKay Shields' investments
in personnel, systems and equipment necessary to manage the Fund, and the fact
that NYLIM is responsible

for paying MacKay Shields' subadvisory fee. In light of these considerations,
the Board concluded that the anticipated profits to be realized by NYLIM and
MacKay Shields were reasonable.

MAINSTAY ASSET MANAGER FUND

The Board noted that this Fund's performance track record appears to be near the
median of its Lipper performance universe. The Board considered NYLIM's addition
of a new portfolio manager to this Fund's management team, and the time and
effort recently expended by NYLIM personnel, as described to the Board, in
evaluating this Fund's investment process and positioning within the fund
family. The Board also considered recent personnel enhancements to NYLIM Equity
Investors, the division of NYLIM that manages the Fund. The Board concluded that
the Fund has an acceptable performance record, although the Board would continue
to monitor NYLIM's enhancements to this Fund and its positioning within the fund
family.

In addition, the Board considered that this Fund's contractual management fee
appears to be among the lowest in its Lipper expense group, and that the Fund's
net management fee, after factoring the impact of expense limitations
voluntarily instituted by NYLIM, also appears to be among the lowest in its
Lipper expense group. In addition, the Fund's net total operating expenses also
appear to be at the lower end of its Lipper expense group. The Board carefully
evaluated NYLIM's proposal to reduce its voluntary expense limitation by 11
basis points, with the result that the Fund's annual expense ratio would
increase by the same amount to a level where, based on information provided to
the Board by NYLIM and Lipper, the Fund's net total operating expenses would
continue to be competitive with other mutual funds in its Lipper expense group.
In considering this proposal, the Board evaluated, among other things, NYLIM's
costs associated with managing this Fund, information provided by NYLIM showing
that the Fund is not profitable to NYLIM under its previous expense structure,
and NYLIM's history of supporting this Fund through voluntary expense
limitations. The Board also acknowledged that, at the Board's request, NYLIM has
now agreed to obtain the Board's approval before raising or removing the expense
limitation it has placed on the Fund. Based on these considerations, the Board
concluded that the management fee was reasonable and compared favorably in
relation to similar portfolios.

The Board also considered whether the Fund's expense structure permitted
economies of scale to be shared with Fund investors. The Board reviewed
information from NYLIM and Lipper showing that the Fund's management fee remains
below its Lipper expense group median as assets hypothetically increase over
time. Based on this information, the Board concluded that the Fund's current
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 continues to grow.

In addition, the Board considered information provided by NYLIM on the costs
associated with managing the Fund and the anticipated profitability of the Fund
to NYLIM. The Board noted that, based on information provided by NYLIM, this
Fund is not profitable to NYLIM at its previous expense structure and current
asset levels. The Board also considered NYLIM's investments in personnel,
systems and equipment necessary to manage the Fund. In light of these
considerations, the Board concluded that the anticipated profits, if any, to be
realized by NYLIM were reasonable.

MAINSTAY BALANCED FUND

The Board considered NYLIM's addition of a new portfolio manager to this Fund's
management team, and the time and effort recently expended by NYLIM personnel in
evaluating this Fund's investment process and position within the fund family.
The Board also considered recent enhancements to NYLIM Equity Investors, the
division of NYLIM that manages the Fund. The Board concluded that these efforts
were reasonably likely to benefit Fund shareholders.

In addition, the Board noted that this Fund's performance track record has been
favorable over both the short term and long term, and is generally in the top
two quartiles in its Lipper performance universe. The Board concluded that the
Fund's performance is satisfactory.

The Board also noted that, although this Fund's overall contractual and net
management fee was above its Lipper expense group median, the Fund's net total
operating expenses are at the lower end of its Lipper expense group. Although
NYLIM has agreed to voluntarily limit this Fund's total operating expenses, this
expense limitation was not triggered. Nonetheless, the Board considered that, at
the Board's request, NYLIM has now agreed to obtain the Board's approval before
raising or removing the expense limitation it has placed on the Fund. Based on
these considerations, the Board concluded that the management fee was reasonable
and compared favorably in relation to similar portfolios.

The Board also considered whether the Fund's expense structure permitted
economies of scale to be shared with Fund investors. The Board considered
information from NYLIM and Lipper showing that the Fund's management fee remains
within a reasonable range of the Lipper expense median as assets hypothetically
increase over time. The Board also noted the recent growth in the Fund's assets,
and accepted NYLIM's proposal to enter into a

 300   MainStay Funds


contractual breakpoint on assets in excess of $1 billion. Based on this
information, the Board concluded that the Fund's current 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 continues to grow.

In addition, the Board considered information provided by NYLIM on the costs
associated with managing the Fund and the anticipated profitability of the Fund
to NYLIM. The Board noted that, based on information provided by NYLIM, this
Fund is not profitable to NYLIM at its current expense structure and asset
levels. The Board also considered NYLIM's investments in personnel, systems and
equipment necessary to manage the Fund. In light of these considerations, the
Board concluded that the anticipated profits, if any, to be realized by were
reasonable.

MAINSTAY CASH RESERVES FUND

The Board considered the Fund's performance track record and concluded that the
Fund's performance is satisfactory and consistent with that of other money
market funds in its Lipper performance universe.

The Board considered, and accepted, NYLIM's proposal to lower the Fund's
contractual management fee to within range of the Lipper expense group median.
In addition, the Board also considered that the Fund's total operating expenses
are below the Lipper expense group median, primarily because of the voluntary
expense limitation NYLIM has placed on the Fund. The Board noted that, at the
Board's request, NYLIM has now agreed to obtain the Board's approval before
raising or removing this expense limitation. Based on these considerations, the
Board concluded that the management fee was reasonable and compared favorably in
relation to similar portfolios.

The Board also considered whether the Fund's expense structure permitted
economies of scale to be shared with Fund investors. The Board considered, and
accepted, NYLIM's proposal to institute a breakpoint on this Fund's management
fee on assets in excess of $500 million. Based on this information, the Board
concluded that the Fund's current 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 continues to grow.

In addition, the Board considered information provided by NYLIM on the costs
associated with managing the Fund and the anticipated profitability of the Fund
to NYLIM. It considered NYLIM's investments in personnel, systems and equipment
necessary to manage the Fund. In light of these considerations, the Board
concluded that the anticipated profits to be realized by NYLIM were reasonable.

MAINSTAY FLOATING RATE FUND

The Board considered that this Fund was launched within the previous year, and
concluded that there was insufficient data to reasonably evaluate the Fund's
performance. The Board noted, however, that the Fund's initial performance
outlook is positive, and that the portfolio management teams' performance track
record in managing similar accounts and portfolios appears to be favorable.

The Board noted that the Fund's contractual management fee is below its Lipper
expense group median, and that the Fund's net total operating expenses are
within range of the median. Although NYLIM has voluntarily agreed to limit this
Fund's total operating expenses, this expense limitation was not triggered.
Nonetheless, the Board considered that, at the Board's request, NYLIM has now
agreed to obtain the Board's approval before raising or removing the expense
limitation it has placed on the Fund. Based on these considerations, the Board
concluded that the management fee was reasonable and compared favorably in
relation to similar portfolios.

The Board also considered whether the Fund's expense structure permitted
economies of scale to be shared with Fund investors. The Board considered
information from NYLIM and Lipper showing that the Fund's management fee remains
below the Lipper expense median as assets hypothetically increase over time.
Based on this information, the Board concluded that the Fund's current 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 continues to grow.

In addition, the Board considered information provided by NYLIM on the costs
associated with managing the Fund and the anticipated profitability of the Fund
to NYLIM. The Board noted that, based on information provided by NYLIM, this
Fund is not profitable to NYLIM at this time, although given the Fund likely
would become profitable to NYLIM in the near future. The Board also considered
NYLIM's investments in personnel, systems and equipment necessary to manage the
Fund. In light of these considerations, the Board concluded that the anticipated
profits, if any, to be realized by NYLIM were reasonable.

MAINSTAY INDEXED BOND FUND

The Board considered this Fund's performance record, noting that the Fund
consistently appears to be in the top quartile of its Lipper performance
universe for one, three, five and ten year periods. The Board concluded that the
Fund's performance is satisfactory.

                                                   www.mainstayfunds.com     301


The Board observed that the Fund's total operating expenses appear to be higher
than those of peer funds in its Lipper expense group. It considered, and
accepted, NYLIM's proposal to lower the Fund's contractual management fee to
within range of the Lipper expense group median. The Board also accepted NYLIM's
proposal to reduce the Fund's expense limitation from 50 basis points to 43
basis points, which places the Fund's net total operating expenses within a
reasonable tolerance of its Lipper expense group median. The Board noted that,
at the Board's request, NYLIM has now agreed to obtain the Board's approval
before raising or removing this expense limitation. In evaluating the overall
reasonableness of the Fund's current expense structure, the Board also
considered the Fund's successful performance track record, and information
provided by NYLIM showing that this Fund is not profitable even under its
previous higher expense structure at current asset levels. Based on these
considerations, the Board concluded that the management fee was reasonable and
compared favorably in relation to similar portfolios.

The Board also considered whether the Fund's expense structure permitted
economies of scale to be shared with Fund investors. The Board considered, and
accepted, NYLIM's proposal to institute a breakpoint on this Fund's management
fee on assets in excess of $1 billion. Based on this information, the Board
concluded that the Fund's current 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 continues to grow.

In addition, the Board considered information provided by NYLIM on the costs
associated with managing the Fund and the anticipated profitability of the Fund
to NYLIM. The Board noted that, based on information provided by NYLIM, this
Fund is not profitable to NYLIM at its current expense structure and asset
levels. The Board also considered NYLIM's investments in personnel, systems and
equipment necessary to manage the Fund. In light of these considerations, the
Board concluded that the anticipated profits, if any, to be realized by were
reasonable.

MAINSTAY INTERMEDIATE TERM BOND FUND

The Board noted that the Fund's performance in early 2002 has detracted from its
long-term performance record. The Board considered MacKay Shields' explanation
that the reasons for the Fund's poor performance in early 2002 was attributable
to its exposure to several underperforming sectors, and the Fund's overweight
position in several poorly performing issuers. The Board considered steps that
MacKay Shields has taken to reposition this Fund in recent years, and the fact
that the Fund now appears to be in the top half of its Lipper performance
universe over the previous year. Based on these considerations, the Board
concluded that the Fund appeared to be positioned for better future performance,
and that the Board would continue to carefully monitor the performance of this
Fund over the coming year.

The Board considered and accepted NYLIM's proposal to lower the Fund's
contractual management fee. Although the contractual management fee proposed by
NYLIM appears to be above the contractual management fee for other portfolios in
the Fund's Lipper expense group, NYLIM's agreement to limit this Fund's total
operating expenses should result in both a net management fee and net total
operating expenses that are each within range of the Fund's Lipper expense group
median. In addition, the Board accepted NYLIM's proposal to further limit the
total operating expenses of the Class A, Class B and Class C shares of the Fund
in an effort to reduce the impact of higher-than-average "other expenses" on the
retail classes of this Fund. The Board also noted that, at the Board's request,
NYLIM has now agreed to obtain the Board's approval before raising or removing
these expense limitations. Based on these considerations, the Board concluded
that the management fee was reasonable.

The Board also considered whether the Fund's expense structure permitted
economies of scale to be shared with Fund investors. The Board considered
information from NYLIM and Lipper showing that the Fund's net management fee
remains within the a reasonable tolerance of the Lipper expense median as assets
hypothetically increase over time. Based on this information, the Board
concluded that the Fund's current expense structure reflects reasonable
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 continues to grow.

In addition, the Board considered information provided by NYLIM and MacKay
Shields on the costs associated with managing the Fund and the anticipated
profitability of the Fund to NYLIM and MacKay Shields. It noted that, based on
information provided to the Board by NYLIM, NYLIM realized a modest profit on
this Fund over the previous year, but that the Fund was not profitable to NYLIM
in previous years. It considered NYLIM's and MacKay Shields' investments in
personnel, systems and equipment necessary to manage the Fund, and the fact that
NYLIM is responsible for paying MacKay Shields' subadvisory fee. In light of
these considerations, the Board concluded that the anticipated profits to be
realized by NYLIM and MacKay Shields were reasonable.

 302   MainStay Funds


MAINSTAY MID CAP OPPORTUNITY FUND

The Board noted that this Fund's performance record appears to be favorable over
both the short term and long term, and is generally in the top two quartiles in
its Lipper performance universe. In addition, the Board considered NYLIM's
addition of a new portfolio manager to this Fund's management team, and the time
and effort recently expended by NYLIM personnel, as described to the Board, in
evaluating this Fund's investment process and positioning within the fund
family. The Board also considered recent personnel enhancements to NYLIM Equity
Investors, the division of NYLIM that manages the Fund. The Board concluded that
the Fund's performance is satisfactory.

The Board also noted that this Fund's contractual and net management fee (after
factoring NYLIM's voluntary expense limitation on the Fund) appears to be below
the median of its Lipper expense group. Moreover, the Fund's total operating
expenses also appear to be below the median of the Fund's Lipper expense group.
In addition, the Board accepted NYLIM's proposal to further limit the total
operating expenses of the Class A, Class B and Class C shares of the Fund in an
effort to reduce the impact of higher-than-average "other expenses" on the
retail classes of this Fund. The Board considered that, at the Board's request,
NYLIM has now agreed to obtain the Board's approval before raising or removing

considered NYLIM's investments in personnel, systems and equipment necessary to

MAINSTAY S&P 500 INDEX FUND

The Board considered this Fund's performance track record, noting that the Fund
consistently has been in the top two quartiles of its Lipper performance
universe for one, three, five and ten year periods. The Board concluded that the
Fund's performance is satisfactory.

The Board considered and accepted NYLIM's proposal to lower the Fund's
contractual management fee to within range of the Lipper expense group median.
It observed that, based on information provided to the Board by NYLIM and
Lipper, the Fund's net management fee and total operating expenses also would
remain within range of the Lipper expense group median, primarily due to the
voluntary expense limitation that NYLIM has placed on the Fund. The Board noted
that, at the Board's request, NYLIM has now agreed to obtain the Board's
approval before raising or removing this expense limitation. Based on these
considerations, the Board concluded that the management fee was reasonable and
compared favorably in relation to similar portfolios.

The Board also considered whether the Fund's expense structure permitted
economies of scale to be shared with Fund investors. The Board accepted NYLIM's
proposal to institute breakpoints on this Fund's management fee on assets over
$1 billion. Based on this information, the Board concluded that the Fund's
current 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
continues to grow.

In addition, the Board considered information provided by NYLIM on the costs
associated with managing the Fund and the anticipated profitability of the Fund
to NYLIM. The Board noted that, based on information provided by NYLIM, this
Fund is not profitable to NYLIM at its current expense structure. The Board also
considered NYLIM's investments in personnel, systems and equipment necessary to
manage the Fund. In light of these considerations, the Board concluded that the
anticipated profits, if any, to be realized by were reasonable.

MAINSTAY SHORT TERM BOND FUND

The Board considered that this Fund's performance track record has been within
range of the Lipper performance universe median over short-term and long-term
periods. The Board concluded that this Fund's performance was reasonably
satisfactory, and that it would continue to actively monitor this Fund's
performance over the coming year.

The Board also noted that, although this Fund's contractual management fee
appeared to be moderately above its Lipper expense group median, the Fund's net
management

                                                   www.mainstayfunds.com     303


fee and net total operating expenses appear to be within range of the Lipper
expense group median, primarily because of NYLIM's voluntary agreement to limit
this Fund's total operating expenses. In addition, the Board accepted NYLIM's
proposal to further limit the total operating expenses of the Class A, Class B
and Class C shares of the Fund in an effort to reduce the impact of
higher-than-average "other expenses" on the retail classes of this Fund. The
Board also noted that, at the Board's request, NYLIM has now agreed to obtain
the Board's approval before raising or removing these expense limitations. Based
on these considerations, the Board concluded that the management fee was
reasonable and compared favorably in relation to similar portfolios.

The Board also considered whether the Fund's expense structure permitted

In addition, the Board considered information provided by NYLIM and MacKay
Shields on the costs associated with managing the Fund and the anticipated
profitability of the Fund to NYLIM and MacKay Shields. It noted that, based on
information provided to the Board by NYLIM, the Fund was not profitable to NYLIM
under its existing expense structure and asset levels. It considered NYLIM's and
MacKay Shields' investments in personnel, systems and equipment necessary to
manage the Fund, and the fact that NYLIM is responsible for paying MacKay
Shields' subadvisory fee. In light of these considerations, the Board concluded
that the anticipated profits, if any, to be realized by NYLIM and MacKay Shields
were reasonable.

MAINSTAY SMALL CAP OPPORTUNITY FUND

The Board noted NYLIM's explanation that the Fund's underperformance in 2000 has
detracted from its 5-year performance record. Nonetheless, based on the data
provided by NYLIM and Lipper, it appears that this Fund's one, three and
ten-year performance track records were in the top two quartiles of its Lipper
performance universe. In addition, the Board considered NYLIM's addition of a
new portfolio manager to this Fund's management team, and the time and effort
recently expended by NYLIM personnel, as described to the Board, in evaluating
this Fund's investment process and positioning within the fund family. The Board
also considered recent personnel enhancements to NYLIM Equity Investors, the
division of NYLIM that manages the Fund. Based on these considerations, the
Board concluded that the Fund's performance was satisfactory.

The Board also noted that, although this Fund's contractual and net management
fee were moderately above its Lipper expense group median, the Fund's net total
operating expenses are within range of the Lipper expense group median. Although
NYLIM has previously voluntarily agreed to limit this Fund's total operating
expenses, this expense limitation was not triggered. However, the Board accepted
NYLIM's proposal to further limit the total operating expenses of the Class A,
Class B and Class C shares of the Fund in an effort to reduce the impact of
higher-than-average "other expenses" on the retail classes of this Fund. The
Board also noted that, at the Board's request, NYLIM has now agreed to obtain
the Board's approval before raising or removing these expense limitations. Based
on these considerations, the Board concluded that the management fee was
reasonable and compared favorably in relation to similar portfolios.

The Board also considered whether the Fund's expense structure permitted
economies of scale to be shared with Fund investors. The Board considered
information from NYLIM and Lipper showing that the Fund's management fee remains
above the Lipper expense median as assets hypothetically increase over time. The
Board agreed that it would continue to evaluate the reasonableness of the Fund's
expense structure as the Fund continues to grow.

In addition, the Board considered information provided by NYLIM on the costs
associated with managing the Fund and the anticipated profitability of the Fund
to NYLIM. It considered NYLIM's investments in personnel, systems and equipment
necessary to manage the Fund. In light of these considerations, the Board
concluded that the anticipated profits to be realized by NYLIM were reasonable.

MAINSTAY CONSERVATIVE ALLOCATION FUND, MAINSTAY MODERATE ALLOCATION FUND,
MAINSTAY MODERATE GROWTH ALLOCATION FUND, AND MAINSTAY GROWTH ALLOCATION FUND

In considering the initial approval of the Management Agreement for these new
Funds (the "Asset Allocation Funds"), the Board noted that the Asset Allocation
Funds had no performance track record, since the Asset Allocation Funds were not
offered to shareholders until April 4, 2005. The Board considered the nature and
scope of the investment management services expected to be provided to the Asset
Allocation Funds by NYLIM. The Board also considered the rationale for selecting
the underlying funds in which the Asset Allocation Funds invest, including the
performance record of those funds.

 304   MainStay Funds


The Board considered the expenses projected to be borne by the Asset Allocation
Funds. In this regard, the Board noted that the Asset Allocation Funds do not
pay a management fee to NYLIM, but that shareholders of the Asset Allocation
Funds indirectly pay the management fees of the underlying funds in which the
Asset Allocation Funds invest. The Board considered NYLIM's process for
monitoring and disclosing potential conflicts in its selection of underlying
funds for the Asset Allocation Funds. The Board also reviewed information
provided to the Board by NYLIM on the fees and expenses of existing funds
similar to the Asset Allocation Funds. In addition, the Board considered NYLIM's
agreement to contractually limit the Asset Allocation Funds' total operating
expenses through October 31, 2005. Based on these considerations, the Board
concluded that the management fees were reasonable and compared favorably in
relation to similar portfolios.

The Board also considered whether each Asset Allocation Fund's expense structure
permitted economies of scale to be shared with investors. The Board reviewed
information from NYLIM showing that each Asset Allocation Fund's management fee
and other expenses are anticipated to remain competitive as each Fund's assets
hypothetically increase over time. Based on this information, the Board
concluded that each Asset Allocation Fund's current expense structure currently
reflects reasonable economies of scale for the benefit of investors. The Board
noted, however, that it would continue to evaluate the reasonableness of each
Asset Allocation Fund's expense structure as the Fund continues to grow.

In addition, the Board considered information provided by NYLIM on the projected
costs associated with managing each Asset Allocation Fund and the anticipated
profitability of the Fund to NYLIM. It considered NYLIM's investments in
personnel, systems and equipment necessary to manage each Asset Allocation Fund.
In light of these considerations, the Board concluded that the anticipated
profits to be realized by NYLIM, if any, were reasonable.

On the basis of the information provided to it and its evaluation of that
information, the Board, which consists entirely of Independent Directors,
concluded that the Agreements were fair and in the best interests of each Fund's
shareholders.
