MESSAGE FROM
THE PRESIDENT

Most domestic and international stock markets advanced during the six months
ended April 30, 2004. The U.S. economy generally improved, with real gross
domestic product growing at a seasonally adjusted annual rate of 4.1% in the
fourth quarter of 2003 and, according to preliminary estimates, rising 4.4% in
the first quarter of 2004. Inflation remained relatively modest throughout the
reporting period but increased enough to reassure the Federal Reserve that
unwanted deflation was no longer a serious concern.

Increases in corporate productivity led to worries that we might be having a
"jobless recovery." In early April, however, the release of March employment
figures showed a dramatic rise in nonfarm payrolls. Unfortunately, the
combination of higher employment and rising inflation suggested that the Federal
Reserve might soon move to raise interest rates. Bond markets adjusted to
accommodate this perception, with yields rising and prices declining in April.
The stock market, which had recorded relatively steady gains since mid-March of
2003, became increasingly volatile from late January through the end of April
2004.

In March and April, bond yields rose to reflect the increasing likelihood of a
less-accommodative monetary policy. Since bond prices and yields tend to move in
opposite directions, several bond indices recorded negative price performance
during the six-month reporting period, but most provided positive total returns.

A weak U.S. dollar helped strengthen the performance of international stocks and
was good news for U.S. exporters. The strengthening Japanese economy was greeted
as positive news by international investors, but moves to decelerate the rapid
economic growth in China were not as favorably received. Several international
markets provided double-digit total returns for the six-month reporting period.

On January 1, 2004, the Eclipse Funds were re-branded as MainStay Funds. The
change was part of a repositioning initiative at New York Life Investment
Management LLC. During the reporting period, some Funds were merged, others
liquidated, and still others renamed. The result was a single, robust, and
integrated mutual fund family that gives investors a more comprehensive array of
alternatives.

At MainStay, each of our Funds seeks to achieve its investment objective through
consistent application of an established investment process. Whether the
investments you've chosen use quantitative analysis, fundamental research, or a
combination of the two, our disciplines remain the same, even when the markets
move. We believe that our time-tested investment strategies can help you pursue
your long-range goals with confidence. We hope to continue to serve your
investment needs for many years to come.

Sincerely,

[/s/ Gary E. Wendlandt]

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 $1,000 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. Performance for Class A, B, and C shares, first
offered 1/1/04, includes the historical performance of Class I shares from
inception (1/2/91) through 12/31/03 adjusted to reflect the applicable sales
charge (or CDSC) and fees and expenses for such shares.

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

Questions answered by portfolio managers Rudolph C. Carryl and Edmund C. Spelman
of MacKay Shields LLC

MAINSTAY ALL CAP GROWTH FUND (FORMERLY ECLIPSE GROWTH EQUITY FUND)

DID THE FUND'S PORTFOLIO-MANAGEMENT MANDATE CHANGE DURING THE REPORTING PERIOD?

Prior to January 2004, the Fund invested primarily in large-cap growth stocks.
As its new name implies, MainStay All Cap Growth Fund has the flexibility to
diversify its portfolio without capitalization restrictions. We have added a
number of new stocks to the portfolio to reflect this added flexibility.

WHAT FACTORS AFFECTED THE STOCK MARKET DURING THE SIX MONTHS ENDED APRIL 30,
2004?

A number of factors kept the market volatile as investor sentiment shifted from
positive to negative. The chief concern was uncertainty over the timing and
magnitude of an anticipated Federal Reserve move to increase interest rates.
Other worries included global terrorist activity, ongoing tensions in Iraq, and
the threat that high oil prices could slow consumer spending. Despite these
negatives, the U.S. economy continued on a strong growth track, and recent
employment data suggest that the long-awaited recovery in the job market is
finally beginning to take hold.

WHY DID THE FUND LAG ITS BENCHMARK OVER THE REPORTING PERIOD?

The primary reason why the Fund underperformed the Russell 3000(R) Index(1) was
an overweighted position in consumer discretionary stocks, where
company-specific issues negatively affected results. The Fund was also hurt by
its underweighted position in consumer staples, a sector that rose as investors
grew more defensive. Company-specific issues also had a negative impact on
several of the Fund's financial holdings.

WHICH SECTORS PRODUCED THE STRONGEST RESULTS DURING THE REPORTING PERIOD?

The Fund's energy holdings gained the most ground, rising 31.0%(2) as the price
of oil rose. This compared with a 27.2% increase for related stocks in the
Index. The Fund's three energy holdings, Weatherford International (+25.2%), BJ
Services (+33.7%), and Baker Hughes (+28.8%) were all strong performers.

The second-best-performing sector was health care, which delivered a 15.8%
return versus an 11.8% increase for related stocks in the Index. The Fund's best
performers in this sector were Caremark Rx (+76.1%), Genentech (+47.0%), Forest
Laboratories (+29.5%), WellPoint Health Networks (+24.1%), and Cardinal Health
(+21.8%).

HOW DID THE FUND'S INDUSTRIAL HOLDINGS PERFORM?

The Fund's industrials holdings rose 8.7% during the first half of the fiscal
year versus a 6.5% increase for related stocks in the Index. Cendant (+19.8%)
and Illinois Tool Works (+16.6%) advanced on strength in their various business
segments. Danaher (+11.4%) was well positioned for an economic recovery. FedEx
(-6.0%) fell on concerns over declining domestic market share. Lockheed Martin
(-2.2%) declined on uncertainty over the direction of defense spending, and we
sold the Fund's position in the stock.

WHICH SECTORS LAGGED THE BENCHMARK?

The Fund's consumer discretionary stocks declined 1.2% versus a 2.1% increase
for the sector in the Index. The Fund did, however, hold a number of strong
performers, including International Game Technology (+91.6%), Harley-Davidson
(+16.7%), and TJX (+16.4%). Unfortunately, these gains were more than offset by
weakness in other holdings. Kohl's (-25.2%) fell on competitive concerns.
InterActive (-13.7%) declined on investor worries over InterActive's third-party
bookings (Expedia and Hotels.com) versus competitors' direct Internet bookings.
Other laggards in the consumer discretionary sector were Bed Bath & Beyond
(-10.7%), Lowe's (-10.9%), and Lennar (-1.2%).

Overall, the Fund's information technology holdings fell 4.8%, versus a 5.3%
decline for related stocks in the Index. Investors generally rotated out of the
sector and into more-defensive issues as business spending remained modest and
evidence mounted that the semiconductor cycle had peaked. The Fund's top
information technology performer was Symantec

Past performance is no guarantee of future results. Investment objectives may
not be met, as the underlying investment options are subject to market risk and
fluctuations in value.

2. Percentages for Fund holdings reflect the total return performance of the
   indicated securities or sectors for the six months ended 4/30/04, or for the
   portion of the reporting period such securities or sector holdings were held
   in the Fund, if shorter. Due to purchases and sales, the performance of Fund
   holdings may differ from the performance of the securities or sectors
   themselves.

(+32.2%), which advanced on strong demand for its antivirus and Internet
security software. Most of the major detractors in the sector were in
semiconductor-related businesses. Among the semiconductor-related holdings that
experienced significant declines were KLA-Tencor (-12.2%), Applied Materials
(-8.6%), Intel (-17.5%), and Texas Instruments (-1.0%). Network storage software
vendor VERITAS Software (-23.8%) declined after its January 2004 announcement
that the company would likely miss sales and profit forecasts in the coming
quarter.

HOW DID THE FUND'S FINANCIAL HOLDINGS PERFORM?

The Fund's financials stocks declined 1.9% during the period versus a 4.1% gain
for related stocks in the Index. Most financial stocks performed well until
early March 2004, when interest-rate concerns began to take hold. Morgan Stanley
(-3.7%) declined even though it handily beat earnings estimates during the
period. Fannie Mae (-1.9%) was eliminated from the portfolio early in the year.
Other financials positions sold during the period included Bank of America and
Fifth Third Bancorp. Both were eliminated as growth slowed and the commercial
loan market remained sluggish. During the period, we added positions in Capital
One Financial, Doral Financial, New Century Financial, IndyMac Bancorp, and New
York Community Bancorp.

WHAT IS YOUR OUTLOOK FOR THE STOCK MARKET AND HOW IS THE FUND POSITIONED GOING
FORWARD?

Investors are clearly focused on the potential for a Federal Reserve
interest-rate hike. Terrorism and geopolitical conflicts are also important
concerns. Despite these issues, we continue to take a long-term view and believe
that holding a broadly based portfolio of best-in-class companies with strong
growth prospects is the appropriate strategy for any market environment.

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 $1,000 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. Performance for Class A, B, and C shares, first
offered 1/1/04, includes the historical performance of Class I shares from
inception (1/2/91) through 12/31/03 adjusted to reflect the applicable sales
charge (or CDSC) and fees and expenses for such shares.

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

Questions answered by portfolio manager Richard A. Rosen of MacKay Shields LLC

MAINSTAY ALL CAP VALUE FUND (FORMERLY ECLIPSE VALUE EQUITY FUND)

DID THE FUND'S PORTFOLIO-MANAGEMENT MANDATE CHANGE DURING THE REPORTING PERIOD?

Prior to January 2004, the Fund invested primarily in large-cap value stocks. As
its new name implies, MainStay All Cap Value Fund now has the flexibility to
diversify its portfolio without capitalization restrictions. We have added some
new stocks to the portfolio to reflect this added flexibility.

WHAT MAJOR FACTORS INFLUENCED THE STOCK MARKET DURING THE SIX MONTHS ENDED APRIL
30, 2004?

In November and December 2003, evidence of an improving economy drove stock
prices higher. Strong growth in corporate profits helped equities continue their
climb in January and February 2004. Fourth-quarter 2003 earnings reports
confirmed a strong growth trend, with rapid revenue growth making a significant
contribution to bottom-line gains.

The interest-rate and inflation outlook remained relatively benign through most
of the reporting period. In the last two months, however, strong employment
figures and rising inflation data led to concerns that the Federal Reserve might
move to raise interest rates. In March and April 2004, the equity market gave
back some of the ground it had earlier gained.

WERE THERE OTHER FORCES AT WORK?

The push and pull of mixed economic signals had a definite effect. While U.S.
economic news was generally favorable, the market was affected by geopolitical
unrest and signs that economic growth in China might decelerate. First-quarter
2004 corporate profit reports were strong, but inflation and interest-rate
concerns seemed to preoccupy investors in April.

WHAT FACTORS CONTRIBUTED TO THE FUND'S STRONG RELATIVE PERFORMANCE?

Excluding sales charges, the Fund outperformed its benchmarks largely because of
good stock selection within the financials, industrials, and information
technology sectors. As of April 30, 2004, the Fund was underweighted in
financials and overweighted in industrials. Some holdings in the Fund's
overweighted positions in energy, materials, and industrials also benefited from
improving trends in manufacturing and industrial data.

HOW DID THE FUND'S FINANCIAL STOCKS IN THIS SECTOR FARE DURING THE PERIOD?

The financials sector was one of the Fund's weakest-performing sectors on an
absolute basis. This was particularly true in April 2004, as concern about the
potential for rising interest rates was reflected in the market. Fortunately,
the Fund avoided many of the stocks that fell sharply, and it had exposure to
some issues that posted good results. The Fund's insurance-related holdings
advanced on positive pricing trends. Allstate, Prudential Financial, and
Hartford Financial Services Group all enhanced the Fund's results during the
reporting period. Bank One and FleetBoston Financial were also strong.
FleetBoston Financial received an acquisition bid from Bank of America in late
October 2003, and FleetBoston Financial's shares were up 13% for the reporting
period.(1) Bank One gained 18%, partly because of a January 2004 takeover bid
from J.P. Morgan Chase.

Unfortunately, the Fund also held financial stocks that detracted from the
Fund's relative performance. Among them were Merrill Lynch, a capital-markets
sensitive stock that fell with the broader equity market, and Washington Mutual,
a lender that might be negatively affected by higher interest rates. Both stocks
were down 8% during the period.

HOW DID THE FUND'S INFORMATION TECHNOLOGY HOLDINGS PERFORM?

Although the information technology sector generally provided lackluster
performance during the reporting period, the Fund's holdings in the sector
strongly outperformed information technology stocks in the Russell 1000(R) Value
Index and the Russell 3000(R) Value Index. The Fund benefited from its position
in Motorola, which rose 36% during the reporting period. Balance sheet strength,
new leadership, and improving operating trends in mobile handsets,
semiconductors, and telecommunications equipment helped Motorola post
first-quarter 2004 earnings well above the most optimistic expectations.

Past performance is no guarantee of future results. Investment objectives may
not be met, as the underlying investment options are subject to market risk and
fluctuations in value.
1. Percentages reflect the price performance of the securities mentioned for the
   six months ended 4/30/04, or for the portion of the reporting period shares
   were held in the Fund, if shorter. Performance percentages do not reflect the
   impact of dividends received, if any. Due to purchases and sales, the
   performance of Fund holdings may differ from that of the securities
   themselves.

Although Advanced Micro Devices posted strong gains in 2003, investors began to
take profits when the company appeared to be embarking on a major spending
initiative. There was also speculation that rival Intel might counter Advanced
Micro Devices' 64-bit microprocessor with one of its own.

WERE THERE OTHER STOCKS THAT ENHANCED OR DETRACTED FROM RESULTS?

The Fund's defense & aerospace industry holdings contributed positively to the
Fund's performance, as government spending helped earnings and cash-flow
generation. Raytheon was up 23%. Northrop Grumman and Boeing each gained 12%.
Within the industrials sector, Navistar International climbed 12%. Navistar
International has benefited from rising heavy-duty truck order rates and, in our
view, has remained inexpensive relative to its earnings power. High energy
prices helped the Fund's integrated energy stocks, with ConocoPhillips rising
26% and ChevronTexaco gaining 25%. We reduced the Fund's positions in these
stocks as they approached our price targets. Bowater managed small gains during
the reporting period, but the position had a negative impact on relative
performance. We remain optimistic about price increases in the paper industry
and expect these holdings to respond favorably.

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

At the end of April 2004, the Fund was overweighted in energy, industrials,
materials, health care, and consumer staples, and underweighted in the consumer
discretionary, financials, and utilities sectors. We remain confident in our
investment disciplines 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 $1,000 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. Performance for Class A, B, and C shares, first
offered 1/1/04, includes the historical performance of Class I shares from
inception (1/2/01) through 12/31/03 adjusted to reflect the applicable sales
charge (or CDSC) and fees and expenses for such shares.

Expenses shown in the table are meant to highlight your ongoing costs only and
do not reflect any transactional costs, such as sales charges (loads),
redemption fees, or exchange fees. Therefore, the third column of the table is
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 had been included, your costs would have been higher.

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

Questions answered by portfolio manager Harvey Fram, CFA, of New York Life
Investment Management LLC

MAINSTAY MID CAP CORE FUND

WHAT MAJOR FACTORS INFLUENCED THE STOCK MARKET DURING THE SIX MONTHS ENDED APRIL
30, 2004?

U.S. equities began the semiannual period with a bang, but the rally fizzled
when the markets experienced a significant downturn in March and April 2004. As
a result, six-month returns for the broadly watched equity indices were rather
muted. As measured by Russell indices,(1) mid-cap stocks outperformed their
large- and small-capitalization counterparts for the six months ended April 30,
2004. Value stocks outperformed growth stocks at all capitalization levels.

WHAT FACTORS MOST SIGNIFICANTLY AFFECTED FUND PERFORMANCE DURING THE SEMIANNUAL
PERIOD?

The Fund's holdings in the telecommunication services and utilities sectors made
the largest positive contributions to performance. Unfortunately, these strong
holdings were not enough to outweigh the effects of the Fund's health care and
industrial positions, which detracted from the Fund's six-month returns.

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

Within the telecommunication services sector, the Fund's overweighted position
in Sprint (PCS Group) (+119.8)(2) made the greatest security-level contribution
to the Fund's performance. Sprint (PCS Group) shares skyrocketed more than 60%
in the first quarter of 2004 alone, as takeover speculation on the heels of the
AT&T Wireless/Cingular deal sparked investor interest. The Fund's underweighted
position in Level 3 Communications (-46.8%), a high-speed communications network
operation, also helped returns during the reporting period. In the utilities
sector, the portfolio's overweighted position in Dallas-based energy company TXU
(+51.1%) made a positive contribution to the Fund's return when the company's
shares surged.

WHICH STOCKS DETRACTED FROM THE FUND'S PERFORMANCE?

Within the health care sector, the Fund's underweighted position in Biogen Idec
(+54.5%), a rapidly growing biotech concern, proved to be the largest
security-level detractor from Fund performance, as the company posted an
impressive six-month gain. The Fund was also hurt by its underweighted position
in medical-device company Zimmer Holdings (+25.1%), which had relatively strong
performance. In the industrials sector, the Fund's overweighted positions in
such laggards as SPX (-7.3%) and JetBlue Airways (-27.9%) had a negative impact
on results. Career Education (+19.5%) had solid earnings and provided relatively
strong performance for the six-month period, but the Fund's underweighted
position relative to the Russell Midcap(R) Index detracted from the Fund's
performance.

WHAT DO YOU ANTICIPATE GOING FORWARD?

We will continue to favor issues with an established history of real revenues
and earnings. If investors become more fundamentally oriented, we believe that
the Fund's model-driven performance will be more likely to produce results in
line with our expectations relative to the equity market as a whole.

not intended as an endorsement of any specific investment.

Past performance is no guarantee of future results. Investment objectives may
not be met, as the underlying investment options are subject to market risk and
fluctuations in value. Investors should note that funds that invest in companies
with market capitalizations below $10 billion involve additional risks. The
securities of these companies may be more volatile and less liquid than the
securities of larger companies.

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 $1,000 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. Performance for Class A and B shares, first
offered 1/1/04, includes the historical performance of Class I shares from
inception (12/27/94) through 12/31/03 adjusted to reflect the applicable sales
charge (or CDSC) and fees and expenses for such shares. Prior to 1/1/04, the
Fund offered Class L shares, which were subject to a 1% sales charge and a 1%
CDSC on

Expenses shown in the table are meant to highlight your ongoing costs only and
do not reflect any transactional costs, such as sales charges (loads),
redemption fees, or exchange fees. Therefore, the third column of the table is
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 had been included, your costs would have been higher.

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

Questions answered by portfolio managers Wesley G. McCain and Kathy A. O'Connor
of New York Life Investment Management LLC

MAINSTAY MID CAP OPPORTUNITY FUND
(FORMERLY ECLIPSE MID CAP VALUE FUND)

WHAT MAJOR FACTORS INFLUENCED THE STOCK MARKET DURING THE SIX MONTHS ENDED APRIL
30, 2004?
Most broadly watched equity indices provided positive performance for the six
months ended April 30, 2004. Mid-caps and small-caps tended to outperform
large-capitalization issues. The market favored the value style over the growth
style of investing at all capitalization levels.

For much of the semiannual period, positive investor sentiment boosted the U.S.
equity markets. Low interest rates and indications of rebounding economic
activity helped to fuel an optimistic outlook. In March and April, however,
heightened geopolitical tensions and growing concerns over potential
interest-rate increases contributed to generally declining equity indices.

WHAT FACTORS MOST SIGNIFICANTLY AFFECTED FUND PERFORMANCE DURING THE SEMIANNUAL
PERIOD?

Fund holdings in the consumer durables & apparel, capital goods, and materials
industry groups showed weaker relative performance than related stocks in the
Russell Midcap(R) Value Index.(1)

The Fund's relative performance was also affected by its underweighted exposure
to the top 50% of companies within the Russell Midcap(R) Value Index, as
measured by market capitalization. For the six months ended April 30, 2004,
these larger mid-cap companies outperformed the smaller mid-cap companies in the
Index. Unlike the Index, which has a larger weighting in securities with larger
market capitalizations, the Fund attempts to have equal weights among the
securities in its portfolio. 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.

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

Software company Autodesk (+73.8%)(2) provided outstanding results. Other strong
performers included Activision (+48.4%), Mandalay Resort Group (+47.4%), Kmart
Holding (+47.3%), and MGIC Investment (+40.9%).

WHICH STOCKS UNDERPERFORMED?

Maxtor (-52.4%), which operates in the computers & peripherals industry, was the
Fund's worst-performing stock during the reporting period. Quanta Services
(-32.4%), Citrix Systems (-24.3%), Ascential Software (-23.7%), and United
States Steel (-18.3%) also detracted from the Fund's performance.

WERE THERE ANY SIGNIFICANT PURCHASES DURING THE REPORTING PERIOD?

The Fund purchases stocks that have relatively improving operating
characteristics and are relatively undervalued based on our proprietary model.
Among the securities that fit the Fund's purchase criteria during the reporting
period were Activision, Apogent Technologies, and Bausch & Lomb.

WHAT STOCKS DID THE FUND SELL?

The Fund sells stocks that exhibit deteriorating operating results and/or are
relatively overvalued. During the reporting period, AdvancePCS was acquired by
Caremark Rx in a stock and cash transaction. The Fund sold its entire position
in American Eagle Outfitters when weakening sales hampered earnings. The Fund
also sold JDS Uniphase when declining demand caused the company to dramatically
reduce its workforce.

DID THE FUND CHANGE ITS INDUSTRY GROUP WEIGHTINGS?

Weighting changes in the Fund result from a combination of security performance,
industry performance, and the Fund's proprietary security selection process.
From the end of October 2003 to the end of April 2004, the Fund increased its
weighting in the banks industry group from 8.70% to 15.46%. The shift reflected
new purchases and improved performance among banks relative to other industry
groups. Over the same period, the Fund decreased its technology hardware &
equipment industry group

Past performance is no guarantee of future results. Investment objectives may
not be met, as the underlying investment options are subject to market risk and
fluctuations in value. Investors should note that funds that invest in companies
with market capitalizations below $10 billion involve additional risks. The
securities of these companies may be more volatile and less liquid than the
securities of larger companies.

   Index.
2. Percentages reflect total returns of Fund holdings in the securities
   mentioned, including purchases and sales, for the six months ended 4/30/04,
   or for the portion of the reporting period such securities were held in the
   Fund, if shorter.

weighting from 12.38% to 7.21%. The decline reflected position sales and weaker
relative performance of the industry group.

HOW DO THE FUND'S WEIGHTINGS DIFFER FROM THOSE OF ITS BENCHMARK?

As of April 30, 2004, the Fund was overweighted relative to the Russell
Midcap(R) Value Index in the health care equipment & services, consumer durables
& apparel, and banks industry groups. The Fund's overweighted position in banks
helped performance, but an overweighted position in consumer durables & apparel
detracted from the Fund's results.

At the end of the reporting period, the Fund was underweighted relative to the
Russell Midcap(R) Value Index in the utilities, insurance, and materials
industry groups. Although the Fund was underweighted in the insurance and
materials industry groups, the Fund's positions underperformed related
securities in the benchmark.

WHAT DO YOU ANTICIPATE GOING FORWARD?

We will continue to utilize the Fund's proprietary quantitative methodologies to
select mid-capitalization stocks of companies that our model indicates are
relatively undervalued and have strong operating characteristics. Whatever the
markets or the economy may bring, the Fund will continue to seek high total
return.

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 $1,000 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
contractual and may be discontinued at any time after December 31, 2004.
Performance for Class A shares, first offered 1/1/04, includes the historical
performance of Class I shares from inception (1/2/91) through 12/31/03 adjusted
to reflect the applicable sales charge and fees and expenses for such shares.

Expenses shown in the table are meant to highlight your ongoing costs only and
do not reflect any transactional costs, such as sales charges (loads),
redemption fees, or exchange fees. Therefore, the third column of the table is
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 had been 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

MAINSTAY S&P 500 INDEX FUND (FORMERLY ECLIPSE INDEXED EQUITY FUND)

WHAT MAJOR FACTORS INFLUENCED THE STOCK MARKET DURING THE SIX MONTHS ENDED APRIL
30, 2004?

When the reporting period began, investor sentiment was changing, since most
indicators seemed to show that the U.S. economy was firmly on the path of
expansion. Bearish gloom gave way to a general sense of optimism, prompting
investors to question how high the stock market might rise. Several factors
served as catalysts in the U.S. economic recovery. These included the lowest
interest rates in more than four decades, President Bush's tax-cut program, the
positive impact of a weaker U.S. dollar on export activity, and slim inventories
that stimulated business investment.

The U.S. equity markets, however, were not able to sustain the tremendous gains
they had seen in the last months of 2003. Stocks surged in early February 2004,
but late February through the end of April proved to be a troublesome time for
U.S. equities. Terrorism muted any momentum that had been building in the equity
markets, as the train bombing in Madrid and the assassination of Hamas leader
Sheik Ahmed Yasin drove equities lower. Ongoing violence against civilians and
coalition troops involved in the rebuilding of Iraq continued to trouble the
financial markets through the end of the semiannual period.

WHAT FACTORS MOST SIGNIFICANTLY AFFECTED FUND PERFORMANCE DURING THE SEMIANNUAL
PERIOD?

Excluding all shares charges, the differences in return between the Fund and its
benchmark, the S&P 500(R) Index,(1) and between the Fund and the average
Lipper(2) S&P 500 Index objective fund over the semiannual period were modest.
Since the Fund includes real-world expenses that a hypothetical index does not,
there may be times when the Fund underperforms the Index. Excluding sales
charges, the Fund's modest outperformance of its Lipper peer group may be
attributed to a difference in annual expenses.

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

Based on total returns alone, wireless services (+44.16%)(4) was the
best-performing subindustry for the six months ended April 30, 2004. Other top-
performing subindustries included Internet retail (+42.69%), oil & gas
refineries (+38.16%), fertilizers & agricultural chemicals (+38.08%), and office
electronics (+27.94%).

Because of their higher weightings in the Index, however, subindustries with
lower total returns were among the five top contributors to the overall
performance of the S&P 500(R) Index. Taking weightings and total returns both
into consideration, the leading subindustry was integrated oil & gas (+19.37%),
followed by pharmaceuticals (+7.52%), health care equipment (+18.56%),
multi-line insurance (+17.97%), and industrial conglomerates (+7.28%).

WHICH SUBINDUSTRIES WERE THE WORST PERFORMERS?

Based solely on total returns, the worst-performing subindustries in the Index
for the reporting period were airlines (-28.85%), semiconductor equipment
(-22.98%), semiconductors (-15.72%), IT consulting (-15.17%), and gold
(-14.57%). Because of a higher Index weighting, semiconductors (-15.72%) had the
greatest negative impact on the total return of the Index for the reporting
period when weightings and total returns were taken into account. Other poor-
performing subindustries by impact were computer hardware (-3.50%),
semiconductor equipment (-22.98%), investment banking & brokerage (-5.30%), and
home improvement retail (-6.65%).

Past performance is no guarantee of future results. Investment objectives may
not be met, as the underlying investment options are subject to market risk and
fluctuations in value. 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.

3. The Global Industry Classification Standard categorizes companies by sector,
   industry group, industry, and subindustry. Results in these sections of the
   semiannual report reflect subindustry 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 subindustries or the securities
   mentioned for the six months ended 4/30/04. Due to purchases and sales, the
   performance of Fund holdings may differ from that of the subindustries or
   securities themselves.

WHO WERE THE CORPORATE LEADERS DURING THE REPORTING PERIOD?

For the six months ended April 30, 2004, the best-performing company in the S&P
500(R) Index based on total return alone was AT&T Wireless Services (+90.48%).
Other top-performing companies based solely on total returns were Autodesk
(+74.03%), Visteon (+68.11%), Biogen Idec (+67.95%), and Novell (+64.22%). As
impressive as these returns may be, the five stocks with the greatest positive
impact on the performance of the S&P 500(R) Index all had higher weightings and
lower total returns. Taking weightings and total returns both into account, the
strongest positive contributors to the performance of the Index for the
six-month period were ExxonMobil (+16.30%), followed by Pfizer (+13.10%),
American International Group (+17.00%), ChevronTexaco (+23.10%), and Altria
Group (+19.10%).

WHICH COMPANIES' STOCKS LAGGED THE S&P 500(R) INDEX?

Not surprisingly, based on total returns alone, the worst-performing security in
the S&P 500(R) Index for the reporting period was a member of the worst-
performing subindustry. That company was Delta Air Lines (-52.23%). Other
poor-performing securities (based on total returns alone) were QLogic (-51.85%),
Ciena (-35.41%), PMC-Sierra (-33.13%), and Apartment Investment & Management
(-31.12%). Similarly, when taking both weightings and total returns into
account, semiconductor company Intel (-22.15%), a company from the worst
performing subindustry, made the greatest negative contribution to the
performance of the Index.

Other laggards (based on weightings and total returns) included Wal-Mart Stores
(-3.30%), Wyeth (-13.70%), Applied Materials (-21.99%), and Comcast (-11.26%).

WERE THERE ANY CHANGES MADE TO THE FUND OR THE INDEX DURING THE 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 our economy. During the six months ended April 30, 2004, there were
eight companies deleted from the Index and eight companies added to it.

WHAT DO YOU ANTICIPATE GOING FORWARD?

We believe that interest rates are a key factor that could affect the outlook
for the U.S. equity market for the remainder of the year. Most investors feel
that the Federal Reserve will not be able to keep the targeted federal funds
rate at its current record low of 1.0%. Indeed, we believe that surging oil
prices may prompt the Federal Reserve to increase interest rates sooner rather
than later to head off the prospect of inflation. Signs of inflation have
already materialized in the Consumer Price Index, the Producer Price Index, and
the ISM Index, the last of which tracks manufacturing costs. Political
uncertainty is another variable that could hold off a stock market rally. The
mere possibility of a change in leadership may add to the instability of the
global landscape. Finally, heightened geopolitical tensions and ongoing
terrorist threats remain obstacles with no clear resolution in sight.

The opinions expressed are those of the portfolio manager 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

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 $1,000 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. Performance for Class A and B shares, first
offered 1/1/04, includes the historical performance of Class I shares from
inception (1/12/87) through 12/31/03 adjusted to reflect the applicable sales
charge (or CDSC) and fees and expenses for such shares. Prior to 1/1/04, 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. Performance for Class L shares,
first offered 12/30/02, includes the historical performance of Class I shares
from inception through 12/29/02 adjusted to reflect the applicable sales charge,
CDSC, and fees and expenses for such shares. Effective 1/1/04, all outstanding
Class L shares of the Fund were converted and/or redesignated Class C shares.

useful in comparing ongoing costs only and will not help you determine the

transactional costs had been included, your costs would have been higher.

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

Questions answered by portfolio managers Wesley G. McCain and Kathy A. O'Connor
of New York Life Investment Management LLC

MAINSTAY SMALL CAP OPPORTUNITY FUND
(FORMERLY ECLIPSE SMALL CAP VALUE FUND)

WHAT MAJOR FACTORS INFLUENCED THE STOCK MARKET DURING THE SIX MONTHS ENDED APRIL
30, 2004?

All broadly watched equity indices provided positive performance for the six
months ended April 30, 2004. Small-capitalization stocks outperformed large-
capitalization stocks. The market favored the value style over the growth style
of investing across all capitalization levels.

For much of the semiannual period, positive investor sentiment boosted the U.S.
equity markets. Low interest rates and indications of rebounding economic
activity helped to fuel an optimistic outlook. In April, however, heightened
geopolitical tensions and growing concerns over potential interest-rate
increases contributed to market uncertainty.

WHAT FACTORS MOST SIGNIFICANTLY AFFECTED FUND PERFORMANCE DURING THE SEMIANNUAL
PERIOD?

The relative performance of Fund holdings in the real estate, energy,
transportation, and media industry groups was stronger than that of related
stocks in the Fund's benchmark, the Russell 2000(R) Value Index.(1)

The Fund's relative performance was also enhanced by its overweighted exposure
to the bottom 25% of companies within the Russell 2000(R) Value Index, as
measured by market capitalization. For the six months ended April 30, 2004,
these smaller small-cap companies outperformed the larger small-cap companies in
the Index. Unlike the Index, which has a larger weighting in securities with
larger market capitalizations, the Fund attempts to have relatively equal
weightings among the securities in its portfolio. It is important to note that
the Fund was invested in some, but not all, of the companies in the Russell
2000(R) Value Index.

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

Wireless telecommunication services company Arch Wireless (+117.0%)(2) provided
outstanding results. Other strong performers included Harvest Natural Resources
(+110.0%), Ocwen Financial (+104.4%), Petroleum Development (+84.9%), and EnPro
Industries (+83.1%).

WHICH STOCKS UNDERPERFORMED?

Quovadx (-64.4%), which operates in the Internet software & services industry,
was the Fund's worst-performing stock during the reporting period. Brightpoint
(-59.4%), Time Warner Telecom (-57.9%), Bookham Technology (-57.6%), and
Friedman's (-46.3%) also detracted from the Fund's results.

WERE THERE ANY SIGNIFICANT PURCHASES DURING THE REPORTING PERIOD?

The Fund purchases stocks that have relatively improving operating
characteristics and are relatively undervalued based on our proprietary model.
Among the securities that fit the Fund's purchase criteria during the reporting
period were Petroleum Development, Titanium Metals, Nuevo Energy, Res-Care, and
Lakes Entertainment.

WHAT STOCKS DID THE FUND SELL?

The Fund sells stocks that exhibit deteriorating operating results and/or are
relatively overvalued. During the reporting period, Enesco Group, R&G Financial,
Dura Automotive Systems, and New Focus were among the stocks that were
eliminated from the Fund's portfolio based on the Fund's proprietary sell
disciplines.

DID THE FUND CHANGE ITS INDUSTRY-GROUP WEIGHTINGS?

Weighting changes in the Fund result from a combination of security performance,
industry performance, and the Fund's proprietary security selection process.
From the end of October 2003 to the end of April 2004, the Fund increased its
weighting in the insurance industry group from 7.8% to 14.4%, in

Past performance is no guarantee of future results. Investment objectives may
not be met, as the underlying investment options are subject to market risk and
fluctuations in value. Percentages reflect total returns of Fund holdings in the
securities mentioned, including purchases and sales, for the six months ended
4/30/04, or for the portion of the reporting period such securities were held in
the Fund, if shorter. 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 development than mid- or
large-capitalization companies.

health care equipment & services from 1.5% to 4.7%, and in energy from 5.2% to
8.2%. The shifts reflected new purchases and improved performance among these
industry groups relative to other industry groups.

Over the same period, the Fund decreased its weightings in banks from 16.7% to
10.8%, in food, beverage & tobacco from 9.4% to 3.8%, and in telecommunication
services from 7.0% to 2.0%. The decline in these industry group weightings
reflected position sales and weaker relative performance of the groups.

HOW DO THE FUND'S WEIGHTINGS DIFFER FROM THOSE OF ITS BENCHMARK?

As of April 30, 2004, the Fund was overweighted relative to the Russell 2000(R)
Value Index in the insurance, energy, consumer durables & apparel, and health
care equipment & services industry groups. The Fund's overweighted positions in
insurance, energy, and consumer durables & apparel helped Fund performance.

At the end of the reporting period, the Fund was underweighted relative to the
Russell 2000(R) Value Index in the capital goods, materials, and banks industry
groups. Security selection in each of these industry groups was quite strong.
Although the Fund was underweighted in capital goods and banks, these industry
groups made a relatively strong contribution to Fund performance. In the
materials industry group, the Fund's underweighted position detracted from
relative performance.

WHAT DO YOU ANTICIPATE GOING FORWARD?

We will continue to utilize the Fund's proprietary quantitative methodologies to
select small-capitalization stocks of companies that our model indicates are
relatively undervalued and have strong operating 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 and reinvestment of dividend and capital-gain
distributions. The graphs assume an initial investment of $1,000. 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.
Performance for the Sweep Shares Class shares, first offered 12/8/98, includes
the performance of Class I shares from inception (1/2/91) through 12/7/98.

1. MainStay Cash Reserves Fund, going forward, will measure its Sweep Shares
   Class performance against the average Lipper institutional money market fund.
   Lipper Inc. is an independent fund performance monitor. Results are based on
   total returns with all dividend and capital-gain distributions reinvested.
2. As of 4/30/04, MainStay Cash Reserves Fund had an effective 7-day yield and
   current yield of 0.62% for the Class I shares and 0.12% for the Sweep Shares
   Class. 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 0.51% and 0.50% for the Class I Shares and 0.01%
   and 0.01% for the Sweep Shares Class. 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.

Expenses shown in the table are meant to highlight your ongoing costs only and
do not reflect any transactional costs, such as sales charges (loads),
redemption fees, or exchange fees. Therefore, the third column of the table is
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 had been 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

MAINSTAY CASH RESERVES FUND (FORMERLY ECLIPSE MONEY MARKET FUND)

WHAT MAJOR FACTORS INFLUENCED THE MONEY MARKETS DURING THE SIX MONTHS ENDED
APRIL 30, 2004?

The sustained war in Iraq, ongoing tensions in the Middle East, and growing
domestic budget deficits continued to influence the financial markets. The money
markets, although relatively quiet, were affected by the overall low level of
interest rates.

The Federal Reserve remained largely out of sight from the money markets. The
targeted federal funds rate remained at 1.0% for the entire period. From
November through March, the LIBOR(1) 30-day to one-year yield curve flattened by
approximately 10 basis points, reflecting the likelihood of no Federal Open
Market Committee action. In April, however, the financial markets began to
anticipate that the FOMC might move to tighten interest rates, and the LIBOR
curve steepened by approximately 47 basis points. Aside from this rise late in
the period, yields on most short-term debt instruments remained relatively
stable.

HOW DID FEDERAL RESERVE POLICY INFLUENCE THE FUND'S DURATION POSITIONING DURING
THE SEMIANNUAL PERIOD?

The Federal Reserve's accommodative monetary policy kept the money market yield
curve relatively flat for most of the semiannual period, making it difficult to
find attractive investment opportunities with more than a six-month maturity. As
a result of current market conditions and the uncertainty regarding when the
Federal Reserve might tighten interest rates, we managed the Fund's duration
using a laddered maturity approach.

WHAT IS A LADDERED MATURITY?

A laddered portfolio staggers maturities to allow different securities in the
portfolio to come due at progressive dates. The strategy was designed to help
the Fund react to future interest-rate increases. The decision caused the Fund's
weighted average maturity to decline to 74 days at the end of April 2004 from 82
days at the end of October 2003.

HOW DID THE FUND INVEST DURING THE REPORTING PERIOD?

We continued to seek opportunities for yield enhancement by investing in
short-term corporate notes. For example, the Fund purchased corporate notes of
Bank One, Minnesota Mining & Manufacturing, AIG SunAmerica, and Lehman Brothers
Holdings.

During the reporting period, we purchased a General Electric floating-rate
security and a DaimlerChrysler asset-backed security. We also purchased Yankee
certificates of deposit in the longer maturity range (four months or longer).
Some names included Toronto Dominion Bank, Barclay's Bank, and Deutsche Bank. A
portion of the Fund's assets were invested in callable agency securities.

DID THE FUND CHANGE ITS ASSET CLASS WEIGHTINGS?

During the six-month reporting period, significant weighting changes included an
increase in the Fund's exposure to short-term corporate notes and a decrease in
the Fund's exposure to asset-backed securities.

WHAT DO YOU ANTICIPATE GOING FORWARD?

In the coming quarter, we expect the Federal Reserve to remain on hold, as it
continues to review economic data in search of a clearer picture of the
economy's potential. In our opinion, the risks appear slanted toward a stronger
economy with inflationary pressure, which will likely lead to Federal Reserve
tightening in the fall.

The opinions expressed are those of the portfolio manager 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.

Past performance is no guarantee of future results and yields will fluctuate.
Investment objectives may not be met, as the underlying investment options are
subject to market risk and fluctuations in value. 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.

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 $1,000 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. Performance for Class A shares,
first offered 1/1/04, includes the historical performance of Class I shares from
inception (1/2/91) through 12/31/03 adjusted to reflect the applicable sales
charge and fees and expenses for such shares.

1. The Citigroup Broad Investment Grade (BIG) Bond Index--the Citigroup BIG Bond
   Index--is an unmanaged index that is considered representative of the U.S.
   investment-grade bond market. Results assume reinvestment of all income and
   capital gains. An investment cannot be made directly into an index.

2. Lipper Inc. is an independent fund performance monitor. Results are based on
   total returns with all dividend and capital-gain distributions reinvested.

Expenses shown in the table are meant to highlight your ongoing costs only and
do not reflect any transactional costs, such as sales charges (loads),
redemption fees, or exchange fees. Therefore, the third column of the table is
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 had been included, your costs would have been higher.

   the period reflect ongoing costs for the four-month period ending April 30,
   2004. Had Class A shares been offered for the six months ended April 30,
   2004, based on a hypothetical 5% return, expenses paid during the period
   would be $4, and the ending account value would be $1,046.

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

Questions answered by portfolio managers Paul Cunningham and Eric Greenman of
the New York Life Investment Management LLC

MAINSTAY INDEXED BOND FUND

WHAT ECONOMIC FORCES AFFECTED THE INVESTMENT-GRADE BOND MARKET DURING THE SIX
MONTHS ENDED APRIL 30, 2004?

Generally, the economy expanded. Real gross domestic product, which had grown at
an unusually high 8.2% in the third quarter 2003, advanced 4.1% in the fourth
quarter. According to preliminary estimates, real gross domestic product grew at
a seasonally adjusted annual rate of 4.4% in the first quarter of 2004.

Through much of the reporting period, disappointing payroll figures grabbed
national headlines and dominated the market's attention. This changed in early
April 2004, however, when the U.S. Department of Labor announced that some
308,000 jobs had been added in March.

HOW DID THE FEDERAL RESERVE RESPOND TO SIGNS OF ECONOMIC GROWTH?

The Federal Reserve maintained its accommodative fiscal policy. The targeted
federal funds rate remained at 1.0%, its lowest level since 1958. As the
probability of "an unwelcome fall in inflation" diminished, the Federal Open
Market Committee began to suggest that removing its policy accommodation was a
possibility, and investors began to anticipate that the FOMC might tighten
monetary policy in the future by raising the targeted federal funds rate.

HOW DID THE OVERALL BOND MARKET PERFORM DURING THE REPORTING PERIOD?

As a result of the weak job market, the five-year Treasury yield fell
approximately 40 basis points, or 0.40%, during the first five months of the
reporting period. When the employment outlook improved, however, Treasury yields
reversed course, rising roughly 85 basis points in April 2004. Volatility in the
Treasury market clouded the outlook and led to increased volatility elsewhere in
the bond market.

Corporate credits provided the strongest performance within the Citigroup Broad
Investment Grade (BIG) Bond Index,(1) returning 1.86% overall, AAA-rated
bonds(2) gained only 0.93%, AA-rated bonds gained 1.04%, and A-rated bonds
gained 1.37%. BBB-rated bonds led the way returning 2.62%.

Mortgage-backed bonds were also relatively strong, returning 1.44% for the six
months ended April 30, 2004. Asset-backed securities returned 1.06%, bonds
issued by government-sponsored entities returned 0.92%, and U.S. Treasuries
returned 0.77%.

HOW DID YOU POSITION THE FUND DURING THE REPORTING PERIOD?

As indexed-fund managers, we seek to track the performance of the Citigroup
(BIG) Bond Index. Since the Fund's portfolio does not contain every security in
the Index, however, its performance may vary. The Fund also incurs real-world
expenses that a hypothetical index does not, so there may be times when the Fund
underperforms the Index. During the reporting period, some of the Fund's
underperformance relative to the Citigroup BIG Bond Index resulted from sector
and issuer selection.

As in the past, one of the indexing strategies we utilized was to diversify the
Fund's holdings in the corporate sector. We are currently buying positions as
low as less than 0.1% of the portfolio (primarily BBB credits) to minimize
issuer overweights, while striving to achieve neutrality among industries,
credit rating categories, and the overall corporate sector.

Past performance is no guarantee of future results. Investment objectives may
not be met, as underlying investment options are subject to market risk and
fluctuations in value. 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.
1. See footnote on page 103 for more information on the Citigroup BIG Bond
   Index.
2. Debt rated AAA has the highest rating assigned by Standard & Poor's, and in
   the opinion of Standard & Poor's, the obligor's capacity to meet its
   financial commitment on the obligation is extremely strong. Debt rated 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.

WHAT IS YOUR OUTLOOK FOR THE ECONOMY AND THE BOND MARKET GOING FORWARD?

As we move into the second half of 2004, several factors may have an impact on
performance in the investment-grade bond market. Economic reports that indicate
continuing strength in the economy, an improving job market, and/or potential
inflation may increase the likelihood of Federal Reserve tightening before the
November elections rather than after. Perceived and actual progress in the
economic cycle will impact Treasury rates as well as securities that typically
trade at a spread to Treasuries. Global issues--including Iraq, terrorist
threats, and other sources of uncertainty--could result in rotation to or from
different quality sectors.

The opinions expressed are those of the portfolio manager as of the date of this
report and are subject to change. There is no guarantee that any forecasts made

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 $1,000 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. Performance for Class A, B, and C shares, first
offered 1/1/04, includes the historical performance of Class I shares from
inception (1/2/91) through 12/31/03 adjusted to reflect the applicable sales
charge (or CDSC) and fees and expenses for such shares.

Expenses shown in the table are meant to highlight your ongoing costs only and
do not reflect any transactional costs, such as sales charges (loads),

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

Questions answered by portfolio managers Gary Goodenough and Christopher Harms
of MacKay Shields LLC

MAINSTAY INTERMEDIATE TERM BOND FUND
(FORMERLY ECLIPSE BOND FUND)

WHAT ECONOMIC FACTORS INFLUENCED THE BOND MARKET DURING THE SIX MONTHS ENDED
APRIL 30, 2004?
The Federal Reserve maintained the targeted federal funds rate at an
accommodative 1.0%, and for much of the period, economic data was mixed. In
April 2004, however, key economic releases showed that core inflation had risen
at a 0.4% monthly rate, nonfarm payrolls had grown by 308,000, and first-
quarter 2004 real gross domestic product had surpassed the 4.1% annualized
growth rate in the fourth quarter of 2003. The risk of deflation appeared to be
waning, while trend-level growth seemed to be firming.

HOW DID THESE FACTORS AFFECT TREASURY YIELDS?

Quite a bit. The two-year, five-year, 10-year, and 30-year benchmark Treasury
issues began the reporting period with yields of 1.8%, 3.2%, 4.3%, and 5.1%,
respectively. Over the next five months, benchmark Treasury yields drifted lower
on inconclusive economic data. In April, interest rates turned sharply higher as
the bond market began to brace for a less stimulative monetary policy. At the
end of the reporting period, the benchmark rates had risen to 2.3%, 3.6%, 4.5%,
and 5.3%, respectively.

HOW DID YOU POSITION THE FUND'S PORTFOLIO?

During the period, there were only modest changes to the Fund's overall asset
allocation. The adjustments we made served to reduce the Fund's overall
duration. Early in the reporting period, we shortened the Fund's duration by
swapping longer-maturity Treasuries for shorter-maturity issues and by selling
some longer-duration lower-coupon mortgage-backed securities. The Fund's
duration fell from 4.61 years to 4.49 years, consistent with our view that
interest rates would gradually rise as 2004 unfolded. To reinforce our view that
interest rates were likely to rise, we purchased mortgage-backed securities
collateralized by balloon loans, because the durations of these securities are
less prone to lengthen when interest rates rise.

WERE THERE ANY PARTICULAR HOLDINGS THAT ENHANCED RESULTS?

The Fund's corporate-bond exposure focused on industries that were aggressively
rationalizing excess capacity to improve their pricing power. We had particular
success with a few triple-B rated issuers,(1) such as Medco Health Solutions and
Fund American. These gains were partially offset by the Fund's holdings in
Citizens Communications, a telecommunications company that unexpectedly
announced its intent to explore strategic alternatives. To protect the portfolio
from increased credit risk, we sold a portion of the position and are closely
monitoring the performance of our remaining holdings in the company.

WHAT IS YOUR OUTLOOK FOR THE ECONOMY AND INTEREST RATES?

We expect employment data to play a role in Federal Reserve decisions, and we
anticipate market turbulence around the time when payroll data is released. Over
the longer term, we expect interest rates to gradually trend higher until the
Federal Reserve initiates a tightening cycle. Even then, interest rates may
remain unsettled until the Federal Reserve specifies the kinds of conditions
that would prompt a neutral stand.

We continue to favor corporate bonds for their total-return potential. If
default rates continue to decline and our economic outlook remains positive, we
may increase the Fund's allocation to high-yield corporate bonds. A portion of
these purchases may include emerging-market bonds. In particular, we will target
areas where globalization and free-trade policies have lowered market barriers.

Past performance is no guarantee of future results. Investment objectives may
not be met, as the underlying investment options are subject to market risk and
fluctuations in value. 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.
1. 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.

The core themes in the Fund's portfolio--positioning for higher interest rates,
tighter credit spreads, and crossover buying from Treasuries to higher-yielding
high-quality sectors, such as asset-backed securities--are working well. We
believe this is an effective strategy and we plan to stay the course.

The opinions expressed are those of the portfolio manager as of the date of this
report and are subject to change. There is no guarantee that any forecasts made

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 $1,000 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. Performance for Class A shares,
first offered 1/1/04, includes the historical performance of Class I shares from
inception (1/2/91) through 12/31/03 adjusted to reflect the applicable sales
charge and fees and expenses for such shares.

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

Questions answered by portfolio managers Claude Athaide, Ph.D., CFA, and Gary
Goodenough of MacKay Shields LLC

MAINSTAY SHORT TERM BOND FUND

WHAT MAJOR FACTORS AFFECTED THE SHORT-TERM BOND MARKET DURING THE SIX MONTHS
ENDED APRIL 30, 2004?

Although the Federal Reserve remained accommodative throughout the reporting
period, economic developments had a major impact on the performance of
short-term bonds.

HOW STRONG WAS THE ECONOMY DURING THE REPORTING PERIOD?

Real U.S. gross domestic product grew at a seasonally adjusted annual rate of
4.1% in the fourth quarter of 2003. Preliminary estimates show that GDP rose
4.4% in the first quarter of 2004. Personal consumption grew at 3.9% while
consumption of durable goods fell 4.2%. Personal consumption has now lagged
overall GDP growth for three quarters. Meanwhile, capital spending grew for
three quarters in a row, with spending on equipment and software advancing at a
double-digit pace during the reporting period.

WERE THERE ANY SIGNIFICANT DEVELOPMENTS IN PRODUCTIVITY AND EMPLOYMENT?

Productivity rose 5.4% while unit labor costs fell at a 1.3% rate over the year
ending March 31, 2004. High productivity enabled firms to meet most of the
pickup in demand without much additional hiring. As a result, corporate profits
rebounded strongly during the semiannual period, increasing 7.2% in the fourth
quarter of 2003 alone. As productivity starts to slow down (it was 3.5% in the
first quarter of this year), employers will have to increase hiring. The March
and April employment reports showed that nonfarm payrolls increased by 625,000
during those two months. The economy has now added approximately 215,000 jobs
per month in 2004.

HOW DID THE SHORT-TERM BOND MARKET REACT TO THE EMPLOYMENT GAINS?

The strength of the March employment figures, along with a positive retail
report and unexpectedly high inflation data, led to a sharp rise in bond yields
during the month of April. The yield on the benchmark two-year Treasury note
rose 73 basis points during the month to finish the reporting period at 2.31%.

HOW WAS THE FUND POSITIONED DURING THE SEMIANNUAL PERIOD?

We positioned the Fund for a flattening yield curve during the period. In fact,
the spread between one-year and five-year constant-maturity Treasury rates
decreased from nearly 200 basis points at the end of October 2003 to a low of
148 basis points in the middle of March, when the rate on the five-year Treasury
fell to 2.64%. Unfortunately, the yield spread between one-year and five-year
Treasuries increased during the last six weeks of the reporting period to 211
basis points, and the performance of the Fund lagged that of its benchmark index
during that span.

DID THE FUND CHANGE ITS ASSET CLASS WEIGHTINGS?

As interest rates rose and yield spreads widened, we used the opportunity to
increase the Fund's exposure to federal agency bonds. Indeed, during the month
of April, we increased the Fund's allocation to federal agency securities from
19.8% on October 31, 2003, to approximately 29% of net assets.

HOW DID THE FUND INVEST DURING THE REPORTING PERIOD?

The Fund continued to invest in a wide range of securities, including
asset-backed securities, mortgage-backed securities, corporate bonds, foreign
corporate bonds, U.S. government securities, and federal agency obligations.

WHAT DO YOU ANTICIPATE GOING FORWARD?

At the end of the six-month period, the Federal Reserve maintained that the
upside and downside risks to economic growth and price stability were about
equal. The Federal Open Market Committee has since suggested that "policy
accommodation can be removed at a pace that is likely to be measured." While
payrolls have finally increased after months of anemic growth, we believe that
strong wage growth will be necessary to sustain spending in the months ahead, as
the effects of the tax cuts fade and higher rates make mortgages less likely to
be refinanced.

We are only slightly defensive on interest rates at this juncture. Evidence from
the federal funds futures market shows that extensive Federal Reserve tightening
has already been priced into the market. The hurdles to profit from a
more-aggressive duration

Past performance is no guarantee of future results. Investment objectives may
not be met, as the underlying investment options are subject to market risk and
fluctuations in value.

posture are quite high, and the opportunity to capture higher yields may become
significantly limited. In the coming weeks, we may continue to increase the
Fund's exposure to federal agency bonds. To take advantage of widening swap
rates, we may also seek opportunities among securities that are priced off swap
rates and have two- or three-year maturities. Certain credit-card asset-backed
securities and commercial mortgage-backed securities fit this profile.

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 $1,000 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. Performance for Class A and B shares, first
offered 1/1/04, includes the historical performance of Class I shares

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

Questions answered by portfolio managers Elias Belessakos, Ph.D. and Jefferson
C. Boyce of New York Life Investment Management LLC

MAINSTAY ASSET MANAGER FUND

HOW DO YOU DECIDE HOW TO ALLOCATE THE FUND'S PORTFOLIO?

We use a proprietary model to assess potential opportunities and allocate assets
within the portfolio's percentage constraints. We use a disciplined methodology
based on the model to estimate expected returns, volatilities, and correlations
on domestic and foreign stock markets and on domestic fixed-income securities.

HOW DID YOU POSITION THE FUND DURING THE SIX MONTHS ENDED APRIL 30, 2004?

During the reporting period, the Fund had an average allocation of 53% to
stocks, 37% to bonds, and 10% to cash. Within the equity allocation, U.S.
equities were underweighted relative to the Fund's custom benchmark(1) at 42% of
net assets and international equities and REITs were overweighted at 10% and 1%,
respectively.

HOW DID THE FUND'S INTERNATIONAL EQUITIES PERFORM?

Within our menu of available assets, international equities had the highest
positive return for the six-month period. The Fund invests in international
equities through foreign futures. During the reporting period, the Japanese
equity market, as measured by the Topix Index,(2) generated the best results,
returning 14.36%. Unfortunately, the Fund's underweighted position in Japanese
stocks reduced the amount of incremental return the portfolio achieved. Our
decision to invest in Italian and Spanish equities, however, proved beneficial
as these markets earned 8.35% and 13.75%, respectively, in local currency terms.
These positions were funded in part by underweighting U.S. large-cap equities.
The U.S. large-cap equity market (as measured by the S&P 500(R) Index),(3)
returned 6.27% for the period, which made the Fund's underweighted position
beneficial. The worst performing portion of the Fund's international allocation
came in Hong Kong, where the Hang Seng Index fell 2.03%. The Fund's slightly
overweighted position in Hong Kong stocks detracted from performance.

HOW DID YOU ALLOCATE THE REST OF THE FUND'S U.S. EQUITY HOLDINGS?

We held an overweighted position in domestic small-cap stocks (as measured by
the S&P SmallCap 600(R) Index)(4) and in mid-cap stocks (as measured by the S&P
MidCap 400(R) Index). This enhanced results, as these market sectors
outperformed their large-cap counterparts, returning 8.47% and 6.93%,
respectively. Real estate investment trusts (as measured by the Morgan Stanley
REIT(R) Index)(5) returned only 2.78%, so the Fund's small but overweighted REIT
position detracted from performance.

HOW DID THE FUND'S BOND ALLOCATION AFFECT PERFORMANCE?

Our decision to overweight bonds and underweight U.S. large-cap stocks detracted
from the Fund's results. The Citigroup BIG Bond Index returned a relatively low
1.32% for the period versus the 6.27% return for the S&P 500(R) Index.

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

The assets allocated by the model to large-cap equities in an actively managed
enhanced-index-fund strategy made a positive contribution to returns by

Past performance is no guarantee of future results. Investment objectives may
not be met, as the underlying investment options are subject to market risk and
fluctuations in value. Foreign securities may be subject to greater risks that
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.

outperforming the S&P 500(R) Index during the reporting period. The allocations
made to the actively managed mid-cap strategy, however, did not fare as well.
Indeed, the mid-cap portion of the portfolio lagged the S&P MidCap 400(R) Index
for the period. Similarly, the allocation made to the actively managed
fixed-income strategy detracted from results when the portfolio underperformed
the Citigroup BIG Bond 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 $1,000 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

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

Questions answered by portfolio manager Joan M. Sabella of New York Life
Investment Management LLC

MAINSTAY BALANCED FUND

WHAT MAJOR FACTORS INFLUENCED THE STOCK AND BOND MARKETS DURING THE SIX MONTHS
ENDED APRIL 30, 2004?

Stocks generally advanced as signs of a rebounding economy fueled investor
optimism. Mid-caps and small-caps tended to outperform and large-capitalization
issues. With weak job growth and low inflation, the Federal Reserve tried to
help the economy by leaving the targeted federal funds rate unchanged from its
45-year low set in June 2003. In March 2004, successes were recorded in job
growth, retail sales, and durable-goods orders, and Treasury notes dropped
significantly. By the end of April 2004, rising inflation had pushed the 10-year
Treasury yield to 4.51%, its highest level since September 2003.

HOW DID THE FUND INVEST DURING THE REPORTING PERIOD?

The Fund continued to invest approximately 60% of its assets in stocks and 40%
in fixed-income securities and cash equivalents. Equity investments included
dividend-paying mid-cap stocks that our proprietary quantitative model found to
be relatively undervalued and to have strong or improving operating
characteristics.

WHAT ABOUT THE FUND'S BOND INVESTMENTS?

We continued to select fixed-income securities based on their credit quality and
duration. The fixed-income portion of the portfolio maintained an
intermediate-term duration and a laddered maturity schedule.

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

Software company Autodesk (+73.8%)(1) provided outstanding results. Other strong
performers included Mandalay Resort Group (+47.4%), Activision (+46.6%), MGIC
Investment (+43.6%), and Kmart Holding (+42.5%).

WHICH STOCKS UNDERPERFORMED?

Maxtor (-52.4%), which operates in the computers & peripherals industry, was the
Fund's worst-performing stock during the reporting period. Other poor performers
included Quanta Services (-33.1%), Citrix Systems (-24.3%), Ascential Software
(-23.7%), and Sears, Roebuck (-23.0%).

WERE THERE ANY SIGNIFICANT PURCHASES DURING THE REPORTING PERIOD?

The Fund purchases stocks that have relatively improving operating
characteristics and are relatively undervalued based on our proprietary model.
Among the securities that fit the Fund's purchase criteria during the reporting
period were Activision, Apogent Technologies, and Bausch & Lomb.

WHAT STOCKS DID THE FUND SELL?

The Fund sells stocks that exhibit deteriorating operating results and/or are
relatively overvalued. During the reporting period, AdvancePCS was acquired by
Caremark Rx in a stock and cash transaction. The Fund sold its entire position
in American Eagle Outfitters when weakening sales hampered earnings. The Fund's
position in JDS Uniphase was sold when declining demand caused operating results
to deteriorate.

DID THE FUND CHANGE ITS INDUSTRY GROUP WEIGHTINGS?

Weighting changes in the Fund result from a combination of security performance,
industry performance, and the Fund's proprietary security selection process.
From the end of October 2003 to the end of April 2004, the Fund increased its
weighting in the banks industry group from 7.23% to 9.98%. The shift reflected
new purchases and improved performance among banks relative to other industry
groups. Over the same period, the Fund decreased its technology hardware &
equipment industry group weighting from 7.39% to 4.32%. The decline reflected
the sale of selected positions and weaker relative performance.

CAN YOU TELL US MORE ABOUT THE FUND'S INDUSTRY GROUP WEIGHTINGS?

As of April 30, 2004, the Fund was overweighted relative to the Russell
Midcap(R) Value Index(2) in the health care equipment & services, consumer

Past performance is no guarantee of future results. Investment objectives may
not be met, as the underlying investment options are subject to market risk and
fluctuations in value.
1. Percentages reflect total returns of Fund holdings in the securities
   mentioned, including purchases and sales, for the six months ended 4/30/04,
   or for the portion of the reporting period such securities were held in the
   Fund, if shorter.
2. 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. 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.

durables & apparel, and software & services industry groups. The overweighted
position in software & services helped Fund performance, while the other
overweighted positions underperformed relative to related securities in the
benchmark index.

At the end of the reporting period, the Fund was underweighted relative to the
Russell Midcap(R) Value Index in the utilities, insurance, and real estate
industry groups. The Fund benefited from its relative underweighted position in
real estate. While the Fund's holdings in the utilities and insurance industry
groups had positive returns, they underperformed relative to securities in the
benchmark.

WHAT DO YOU ANTICIPATE GOING FORWARD?

The Fund will continue to focus on securities that fit its stated objective and
its valuation, quality, duration, and maturity parameters.

September 21, 1990. Eclipse Funds (the "Trust"), a Massachusetts business trust,
was established on July 30, 1986. The Company and the Trust (collectively the
"Funds") are registered as open-end management investment companies under the
Investment Company Act of 1940, as amended, ("Investment Company Act") and are
comprised of twelve separate investment portfolios (individually referred to as
a "Fund").

The Funds commenced operations on the dates indicated below:

On December 29, 2000, the Mid Cap Core Fund sold shares to NYLIFE Distributors
LLC ("NYLIFE Distributors"), an indirect wholly-owned subsidiary of New York
Life Insurance Company ("New York Life"), at a net asset value of $10.00. This
Fund commenced investment operations the following business day on January 2,
2001.

On October 28, 2003, the Tax Free Bond Fund ceased operations. On December 30,
2003, the Tax-Managed Equity Fund ceased operations. On January 29, 2004, the
International Broad Market and the International Equity Funds ceased operations.
These Funds were formerly portfolios of the Company.

On December 11, 2003 and pursuant to shareholder approval, the assets and
liabilities of the Eclipse Core Bond Plus Fund were acquired by the Eclipse Bond
Fund which was subsequently renamed MainStay Intermediate Term Bond Fund. Also
on December 11, 2003 and pursuant to shareholder approval, the assets and
liabilities of the Eclipse Ultra Short Duration Fund were acquired by the
Eclipse Short Term Bond Fund which was subsequently renamed MainStay Short Term
Bond Fund.

Effective January 1, 2004, each series of Eclipse Funds Inc. and Eclipse Funds
were rebranded as "MainStay."

Each Fund offers one or more of the following six classes of shares: Class A,
Class B, Class C, Class I, Class R1 and Class R2 shares. Balanced Fund offers
six classes of shares: Class A, Class B, Class C, Class I, Class R1 and Class
R2. All Cap Growth Fund, All Cap Value Fund, Mid Cap Core Fund, Mid Cap
Opportunity Fund, Small Cap Opportunity Fund, Intermediate Term Bond Fund and
Asset Manager Fund each offer four classes of shares: Class A, Class B, Class C
and Class I shares. S&P 500 Index Fund, Indexed Bond Fund and Short Term Bond
Fund each offer Class A and Class I shares. Cash Reserves Fund offers Class I
shares and another class of shares, the Sweep Shares Class.

Class A shares are offered at net asset value per share plus an initial sales
charge. No sales charge applies on investments of $1 million or more (and
certain other qualified purchases) in Class A shares, but a contingent deferred
sales charge is imposed on certain redemptions of such shares within one year of
the date of purchase. Class B shares and Class C shares are offered without an
initial sales charge, although a declining contingent deferred sales charge may
be imposed on redemptions made within six years of purchase of Class B shares
and a 1% contingent deferred sales charge may be imposed on redemptions made
within one year of purchase of Class C shares. The Class I, Class R1 and Class
R2 shares and the Sweep Shares Class are offered at net asset value without
imposition of a front-end sales charge or a contingent deferred sales charge.
Distribution of Class A, Class B, Class C, Class R1 and Class R2 shares each
commenced on January 1, 2004, except with respect to the Class C shares of Mid
Cap Opportunity Fund, Small Cap Opportunity Fund and Balanced Fund, the L Class
shares of which commenced operations on December 30, 2002 and were renamed the
Class C shares on January 1, 2004. Each Fund's No-Load Class shares were renamed
the Class I shares on January 1, 2004. Each Fund's Service Class shares ceased
operations on January 9, 2004.

Each class of shares bears the same voting (except for issues that relate solely
to one class), dividend, liquidation and other rights and conditions except that
the classes are subject to different distribution fee rates. Class A, Class B,
Class C, and Class R2 shares and the Sweep Shares Class each bear distribution
and/or service fee payments under a distribution plan pursuant to Rule 12b-1
under the Investment Company Act. In addition, the Class R1 and R2 shares and
the Sweep Shares Class each bear service fee payments under a shareholder
service plan.

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 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 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 electronic data processing techniques if such prices are
deemed by the Fund's Manager to be representative of market values at the
regular close of business of the Exchange. 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 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. Portfolio securities of Cash Reserves Fund are valued
at their amortized cost. 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.

Certain events 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 Manager or Subadvisor conclude that such events
may have affected the accuracy of the last price reported on the local foreign
market, the Manager or Subadvisor may, pursuant to procedures adopted by the
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.

NOTES TO FINANCIAL STATEMENTS UNAUDITED (CONTINUED)

(C) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are
recorded on the ex-dividend date. For the Cash Reserves Fund, 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 their net
investment income and net realized capital gains no less frequently 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.

New York Life Investment Management LLC ("NYLIM") has 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. For the six months ended
April 30, 2004, the Funds' expenses (transfer agent fees and expenses) were
reduced by $3,310, $42,247 and $39,765, respectively, under these arrangements.

(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.

(F) USE OF ESTIMATES.  The preparation of financial statements in accordance
with accounting principles generally accepted in the United States of America
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 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

 204   MainStay Funds


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 6).

(H) FUTURES CONTRACTS.  A futures contract is an agreement to purchase or sell a
specified quantity of an underlying instrument at a specified future date and
price, or to make or receive a cash payment based on the value of a 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).

(I) 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.

(J) 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.

(K) 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 6).

NOTE 3 -- FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER AND SUBADVISOR.  NYLIM (or the "Manager"), an indirect wholly-owned
subsidiary of New York Life, serves as manager and provides management services

respectively. The Class B and Class C Plans provide that the Class B and Class C
shares of the Funds also incur a service fee at the annual rate of 0.25% of the
average daily net asset value of the Class B or Class C shares of the Funds,
respectively. Pursuant to the Sweep Shares Class Plan for the Cash Reserves
Fund, the Distributor, NYLIFE Securities Inc., an indirect wholly-owned
subsidiary of New York Life, or any other broker-dealer or other financial
institution, is entitled to receive a monthly service fee from the Cash Reserves
Fund at an annual rate of 0.25% of the average daily net assets of the Fund's
Sweep Shares Class for account sweep and other distribution-related services.

through its affiliates or independent third parties, various distribution-
related, shareholder and administrative support services to shareholders of the
Class R1 and Class R2 shares and the Sweep Shares Class shares. For its

At October 31, 2003, for federal income tax purposes, capital loss
carryforwards, as shown in the table below, were available to the extent
provided by regulations to offset future realized gains of each respective Fund
through the years indicated. To the extent that these loss carryforwards are
used to offset future capital gains, it is probable that the capital gains so
offset will not be distributed to shareholders.

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 10 -- OTHER MATTERS:

(A) On August 27, 2003 KPMG LLP (KPMG) was selected to replace the predecessor
independent auditor as the Company's and the Trust's independent auditor for the
2003 fiscal year. The selection of KPMG as its independent auditor was
recommended by the Company's and the Trust's audit committee, comprised of all
independent Directors/Trustees, and was approved by the Company's Board of
Directors and the Trust's Board of Trustees.

The predecessor independent auditor's reports on the Company's and the Trust's
financial statements for the years ended October 31, 2002 and 2001 did not
contain an adverse opinion or a disclaimer of opinion and were not qualified or
modified as to uncertainty, audit scope or accounting principles. During such
fiscal years, and through the date of engagement of KPMG, there were no
disagreements between the Company and the Trust and the predecessor independent
auditor on any matter of accounting principles or practices, financial statement
disclosure, or auditing scope or procedures, which such disagreements, if not
resolved to the satisfaction of the predecessor independent auditor, would have
caused them to make reference to the subject matter of the disagreement in
connection with their reports on the financial statements for such years.

(B) 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. Except as described below, neither NYLIM nor the funds advised by it
have any reason to believe that they have been targeted as the subject of any
governmental or regulatory enforcement action.

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. NYLIM
and the MainStay Equity Index Fund are currently seeking to resolve the SEC
Staff's concerns regarding these matters, although there can be no assurance at
this time as to the outcome of these efforts.
