 2   MainStay Capital Appreciation Fund


MESSAGE FROM
THE PRESIDENT

During the 12 months ended October 31, 2004, the U.S. stock market advanced, but
its pace and direction were by no means steady. Small- and mid-capitalization
stocks tended to outperform large-cap issues, and value stocks generally
outperformed growth stocks.

Economic activity, as measured by gross domestic product, increased from 4.2% in
the fourth quarter of 2003 to 4.5% in the first quarter of 2004. The pace of
economic growth slowed to 3.3% in the second quarter of 2004, and according to
preliminary estimates from the Bureau of Economic Analysis, gross domestic
product grew at a seasonally adjusted annual rate of 3.9% in the third quarter
of 2004.

Interest rates began the reporting period at a low 1.00%. In June 2004, the
Federal Open Market Committee responded to expanding output and improved labor
markets by raising the targeted federal funds rate by 25 basis points. Similar
moves in August and September brought the targeted federal funds rate to 1.75%.
In its September 2004 release, the Federal Open Market Committee affirmed its
belief that monetary policy remained accommodative.

Despite rising interest rates, bond markets generally advanced. High-yield bonds
and emerging-market debt were particularly strong. The U.S. dollar declined
relative to most other currencies, which helped U.S. exporters.

In pursuing its investment objective, each MainStay Fund consistently seeks to
apply a well-defined investment process in all market environments. We believe
that a consistent, disciplined investment approach can help investors make more
prudent and practical decisions regarding their investments.

In the report that follows, you'll find additional information about the market
forces, investment decisions, and individual securities that affected your
MainStay Fund during the 12 months ended October 31, 2004. We thank you for
investing with us, and we look forward to many years of continued service in
your behalf.

Sincerely,

/s/ GARY E. WENDLANDT

Gary E. Wendlandt
President

Performance tables and graphs do not reflect the deduction of taxes that a
shareholder would pay on distributions or Fund-share redemptions. Total returns
reflect change in share price, reinvestment of dividend and capital-gain
distributions, and maximum applicable sales charges explained in this paragraph.
The graphs assume an initial investment of $10,000 and reflect the deduction of
all sales charges that would have applied for the period of investment. Class A

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

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

CAN YOU BRIEFLY DESCRIBE THE FUND'S INVESTMENT APPROACH?

The Fund invests in securities of U.S. companies with investment characteristics
such as participation in expanding product or service markets, increasing unit
sales volume, increasing return on investment, and better-than-average growth in
revenues and earnings when compared to stocks of the S&P 500(R) Index.(1) In
implementing this strategy, the Fund maintains a flexible approach and may
invest in various types of companies and securities. We look for companies that
we feel are ready for a rise in price or may experience acceleration in growth
of earnings, possibly as a result of changes in management, products, consumer
demand, or the economy. We may sell a security if we no longer believe it will
contribute to meeting the Fund's investment objective.

WHAT KEY FACTORS INFLUENCED THE EQUITY MARKETS DURING THE 12 MONTHS ENDED
OCTOBER 31, 2004?

Arguably the biggest factor was the 78% rise in the price of crude oil, since it
stoked inflation fears and could put a damper on consumer spending. Middle
Eastern tensions, news from Iraq, and concerns about another domestic terrorist
attack all had an impact on the markets.

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

Symantec, a leading provider of Internet-security software, showed consistently
strong earnings growth and made a significant contribution to the Fund's
performance. UnitedHealth Group's earnings and top-line growth benefited from
the company's alliance with top-tier regional health plans and plan
administrators. This arrangement led to network savings and accelerated
membership growth. Danaher Corporation benefited from a realignment strategy
that focused on enhancing earnings growth through strategic acquisitions.
Earnings-per-share growth rose from 3% in 2002 to 20% in 2003 and is projected
to rise to 39% for 2004. Illinois Tool Works benefited from the economic
recovery and the accompanying increase in business capital investment.
Accelerating growth in earnings has helped propel the company's stock price
higher. Harley-Davidson, the motorcycle company, managed to outperform analysts'
earnings estimates by maintaining strong sales and expanding margins.

WHICH STOCKS DETRACTED FROM THE FUND'S PERFORMANCE?

Veritas Software is a leading vendor of enterprise storage-management products.
After achieving a 52-week high in mid-January of this year, the stock fell on
concerns about accounting irregularities, failure to meet analysts' top-line
expectations in early July, and competitive issues. Despite recent improvements,
the stock hurt performance.

New York Community Bancorp suffered from concerns about rising interest rates
affecting New York Community Bank's variable rate debt and possibly creating a
margin squeeze. In response to this situation, we sold the stock in October.

Intel, Applied Materials, and Texas Instruments were all affected by a slowdown
in semiconductor orders. Although all three stocks have begun to recover, they
all detracted from the Fund's performance during the reporting period.

WERE THERE ANY SIGNIFICANT PURCHASES DURING THE 12 MONTHS ENDED OCTOBER 31,
2004?

The Fund purchased Harmon International in October, based on the company's
improving sales and earnings growth and increasing penetration in the luxury
automobile market. L-3 Communications manufactures and markets intelligence,
surveillance, and reconnaissance products. We began buying the stock in July,
based on increased strength in security and defense spending. The Fund purchased
Nike in July as the company continued to experience strength across all of its
athletic product categories and in most of its major global markets. We bought
shares of electronic-products retailer Best Buy in October 2004 for the
Company's reasonable valuation relative to growth prospects and because of sales
trends that have recently been positive. We began buying Capital One Financial
shares in March, based on the company's reasonable valuation relative to its
earnings-growth prospects. All of these stocks have had a positive impact on the
Fund's performance for the portion of the reporting period they were held in the
Fund.

WHICH SECURITIES DID YOU SELL DURING THE REPORTING PERIOD?

Marsh & McLennan is a well-diversified financial services company that owns
Marsh, a risk and insurance services firm; Putnam, a mutual fund company; and
Mercer Consulting Group, a provider

                                                     www.mainstayfunds.com     7


of consulting services. We began selling Marsh & McLennan stock in December of
2003, because of slowing growth and asset losses in the company's Putnam mutual
fund unit. The Fund's average sale price was $46.89, well ahead of the stock's
$27.66 closing price on October 29, 2004.

Clear Channel Communications owns and operates a large network of radio and TV
stations around the country and has operations in outdoor advertising and live
entertainment. We sold the Fund's entire position in June and July, which proved
to be a positive move when the stock moved even lower before the end of the
reporting period.

Coca-Cola is the world's leading manufacturer of carbonated soft drinks,
noncarbonated soft drinks, and bottled water. When the company's growth outlook
began to deteriorate, we sold the Fund's entire position in March at
approximately $50 per share. The decision was positive, since the stock reached
a 52-week low of $38.30 on October 26, 2004.

Forest Laboratories is a pharmaceutical company that manufactures and sells both
branded and generic drugs. When concerns mounted over potential problems with
the class of antidepressant drugs the company sells, the share price began to
fall. Fortunately, we managed to sell at an average price well above the stock's
value on the last day of the reporting period.

Fifth Third Bancorp is a well-diversified financial services company whose
businesses include retail banking, commercial banking, investment advisory, and
data processing. We opted to close out our position in the stock during the
fiscal year based on the company's moderating growth rate and deteriorating
margins. The decision proved to be a positive one as the stock price continued
to drift lower.

HOW DID THE FUND'S SECTOR WEIGHTINGS CHANGE OVER THE 12-MONTH REPORTING PERIOD?

We increased the Fund's weighting in consumer discretionary stocks from 18.2% at
the beginning of the reporting period to 23.1% at the end. The Fund's energy
holdings, which stood at 1.6% of net assets on October 31, 2003, increased to
4.5% of net assets on October 31, 2004. Industrial holdings increased from 11.4%
at the beginning of the reporting period to 17.5% at the end.

We trimmed the Fund's consumer staples weighting from 8.2% at the beginning of
the reporting period to 3.7% at the end. Over the same period, financials
holdings moved from 10.3% to 7.3% of net assets, information technology from
28.0% to 20.9%, and materials from 2.8% to 2.0%.

HOW DID THIS COMPARE WITH THE RUSSELL 1000(R) GROWTH INDEX?

As of October 31, 2004, the Fund was overweighted relative to the Russell
1000(R) Growth Index(2) in the consumer discretionary, energy, industrials, and
materials sectors. At the same time, the Fund was underweighted relative to the
Index in consumer staples, financials, health care, and information technology.
The Fund held no positions in the telecommunications services or utilities
sectors. The Fund's overweighted position in consumer discretionary and its
underweighted position in consumer staples proved to be appropriate sector
allocations, but individual holdings in these sectors detracted from
performance. The Fund's significantly underweighted information technology
position proved detrimental in September and October, when investors bid up many
technology stocks. The Fund's overweighted positions in both the energy and
industrials sectors, together with strong stock selection, had a positive impact
on the Fund's performance.

WHAT IS YOUR OUTLOOK FOR THE FUND IN THE COMING MONTHS?

With the uncertainty of the presidential election now behind us, we expect
investors to refocus their attention on company fundamentals, which on balance
remain fairly strong. Although high energy prices and the threat of terrorism
remain risk factors, we believe that the combination of a low interest-rate
environment, moderate economic growth, and strengthening employment should help
to drive stocks higher in the coming year.

NOTES TO FINANCIAL STATEMENTS

NOTE 1 -- ORGANIZATION AND BUSINESS:

The MainStay Funds (the "Trust") was organized on January 9, 1986 as a
Massachusetts business trust. The Trust is registered under the Investment
Company Act of 1940, as amended (the "1940 Act"), as an open-end management
investment company and comprises twenty-two funds (collectively referred to as
the "Funds"). These financial statements and notes relate only to MainStay
Capital Appreciation Fund (the "Fund"), a diversified fund.

The Fund currently offers four classes of shares. Class A shares, whose
distribution commenced on January 3, 1995, 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 within one year of purchase of Class C
shares. Distribution of Class B shares and Class C shares commenced on May 1,
1986 and September 1, 1998, respectively. Class I shares are not subject to
sales charge. Distribution of Class I shares commenced on January 1, 2004. Class
A shares, Class B shares, Class C shares and Class I shares bear the same voting
(except for issues that relate solely to one class), dividend, liquidation and
other rights and conditions. Each class of shares other than Class I shares
bears distribution and/or service fee payments under a distribution plan
pursuant to Rule 12b-1 under the 1940 Act. Class I shares are not subject to a
distribution or service fee.

The Fund's investment objective is to seek long-term growth of capital. Dividend
income, if any, is an incidental consideration.

NOTE 2 -- SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with generally accepted
accounting principles and follows the significant accounting policies described
below.

(A) SECURITIES VALUATION.  Equity securities are valued at the latest quoted
sales prices as of the close of 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. 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.
Securities for which market quotations are not readily available are valued by
methods deemed by the Board of Trustees to represent fair value. Reasons for
which securities may be valued in this manner include, but are not limited to,
trading for a security has been halted or suspended, a security has been
de-listed from a national exchange, or trading on a security's primary market is
temporarily closed at a time when under normal conditions it would be open. The
Fund did not hold securities at October 31, 2004, that were valued in such
manner.

(B) SECURITIES LENDING.  The Fund may lend its securities to broker-dealers and
financial institutions. The loans are collateralized by cash or securities at
least equal at all times to the market value of the securities loaned. The Fund
may bear the risk of delay in recovery of, or loss of rights in, the securities
loaned should the borrower of the securities experience financial difficulty.
The Fund receives compensation for lending its securities in the form of fees or
it retains a portion of interest on the investment of any cash received as
collateral. The Fund also continues to receive interest and dividends on the
securities loaned and any gain or loss in the market price of the securities
loaned that may occur during the term of the loan will be for the account of the
Fund. (See Note 7.)

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

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

(D) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are
recorded on the ex-dividend date. The Fund intends to declare and pay any
dividends quarterly and capital gain distributions, if any, annually. 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.

The following table discloses the current year reclassifications between net
investment loss and additional paid-in-

 18   MainStay Capital Appreciation Fund


capital arising from permanent differences; net assets at October 31, 2004, are
not affected.

<Table>
<Caption>
     NET INVESTMENT            ADDITIONAL
          LOSS               PAID-IN CAPITAL
                         
      $17,017,118             $(17,017,118)
</Table>

The reclassification for the Fund is due to the fact that net operating losses
cannot be carried forward for federal income tax purposes.

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

(F) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred except where direct allocations of expenses can be made. Expenses
(other than expenses incurred under the distribution plans) are allocated to
separate classes of shares based upon their relative net asset value on the date
the expenses are incurred. The expenses borne by the Fund, including those of
related parties to the Fund, are shown in the Statement of Operations.

(G) USE OF ESTIMATES.  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.

NOTE 3 -- FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER AND SUBADVISOR.  New York Life Investment Management LLC ("NYLIM" or
the "Manager"), an indirect wholly-owned subsidiary of New York Life Insurance
Company ("New York Life"), serves as the Fund's manager. The Manager provides
offices, conducts clerical, recordkeeping and bookkeeping services, and keeps
the financial and accounting records required for the Fund. The Manager also
pays the salaries and expenses of all personnel affiliated with the Fund and all
the operational expenses that are not the responsibility of the Fund. MacKay
Shields LLC (the "Subadvisor"), a registered investment advisor and indirect
wholly-owned subsidiary of New York Life, is responsible for the day-to-day
portfolio management of the Fund.

The Trust, on behalf of the Fund, pays the Manager a monthly fee for services
performed and the facilities furnished at an annual rate of 0.72% of the Fund's
average daily net assets on assets up to $200 million, 0.65% annually on assets
from $200 million to $500 million and 0.50% on assets in excess of $500 million.
For the year ended October 31, 2004 the Manager earned from the Fund $8,736,271.

Pursuant to the terms of a Sub-Advisory Agreement between NYLIM and MacKay
Shields, the Manager paid the Subadvisor a monthly fee at an annual rate of
0.36% of the Fund's average daily net assets on assets up to $200 million,
0.325% on assets from $200 million to $500 million and 0.25% on assets in excess
of $500 million.

(B) DISTRIBUTION AND SERVICE FEES.  The Trust, on behalf of the Fund, has a
Distribution Agreement with NYLIFE Distributors LLC ("the Distributor"), an
indirect wholly-owned subsidiary of New York Life. The Fund, with respect to
each class of shares other than Class I shares, has adopted distribution plans
(the "Plans") in accordance with the provisions of Rule 12b-1 under the 1940
Act. Pursuant to the Class A Plan, the Distributor receives a monthly fee from
the Fund at an annual rate of 0.25% of the average daily net assets of the
Fund's Class A shares, which is an expense of the Class A shares of the Fund for
distribution or service activities as designated by the Distributor. Pursuant to
the Class B and Class C Plans, the Fund pays the Distributor a monthly fee,
which is an expense of the Class B and Class C shares of the Fund, at the annual
rate of 0.75% of the average daily net assets of the Fund's Class B and Class C
shares. The Distribution Plans provide that the Class B and Class C shares of
the Fund 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 Fund. Class I
shares are not subject to a distribution or service fee.

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

(C) SALES CHARGES.  The Fund was advised by the Distributor that the amount of
sales charges retained on sales of Class A shares was $78,181 for the year ended
October 31, 2004. The Fund was also advised that the Distributor retained
contingent deferred sales charges on redemptions of Class A, Class B and Class C
shares of $10,291, $770,578 and $1,854, respectively, for the year ended October
31, 2004.

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

(D) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT.  NYLIM
Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's
transfer, dividend disbursing and shareholder servicing agent. NYLIM Service has
entered into an agreement with Boston Financial Data Services ("BFDS") pursuant
to which BFDS will perform certain of the services for which NYLIM Service is
responsible. Transfer agent expenses for the year ended October 31, 2004
amounted to $5,824,569.

(E) NON-INTERESTED TRUSTEES.  Non-Interested Trustees are paid an annual
retainer fee of $45,000, $2,000 for each Board meeting, $1,000 for each
Committee meeting and $500 for each Valuation Subcommittee telephonic meeting
attended plus reimbursement for travel and out-of-pocket expenses. The Lead
Non-Interested Trustee is also paid an annual retainer fee of $20,000. The Audit
Committee Chairman receives an additional $2,000 for each meeting of the Audit
Committee attended and the Chairpersons of the Brokerage Committee, Operations
Committee and Performance Committee each receive an additional $1,000 for each
meeting of the Brokerage Committee, Operations Committee and Performance
Committee attended, respectively. In addition, each Non-Interested Trustee is
paid $1,000 for attending meetings of the Non-Interested Trustees held in
advance of or in connection with Board/Committee meetings. The Trust allocates
trustees fees in proportion to the net assets of the respective Funds. Thus the
Capital Appreciation Fund only pays a portion of the fees identified above.

(F) OTHER.  Fees for the cost of legal services, included in Professional fees
as shown on the Statement of Operations, provided to the Fund by the Office of
the General Counsel of NYLIM amounted to $45,714 for the year ended October 31,
2004.

The Fund pays the Manager a monthly fee for recordkeeping services provided
under the Accounting Agreement at the annual rate of 1/20 of 1% for the first
$20 million of average monthly net assets, 1/30 of 1% of the next $80 million of
average monthly net assets and 1/100 of 1% of any amount in excess of $100
million of average monthly net assets. Fees for recordkeeping services provided
to the Fund by the Manager amounted to $183,589 for the year ended October 31,
2004.

NOTE 4 -- CUSTODIAN:

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

NOTE 5 -- FEDERAL INCOME TAX:

As of October 31, 2003, the components of accumulated loss on a tax basis were
as follows:

<Table>
<Caption>
 ACCUMULATED CAPITAL     UNREALIZED    TOTAL ACCUMULATED
  AND OTHER LOSSES      APPRECIATION         LOSS
                                 

   $(324,126,195)       $199,972,185    $(124,154,010)
</Table>

The difference between book-basis and tax-basis unrealized appreciation is
primarily due to wash sale deferrals.

At October 31, 2004, for federal income tax purposes, capital loss carryforwards
of $324,126,195 were available as shown in the table below, to the extent
provided by regulations, to offset future realized gains of the Fund through the
years indicated. To the extent that these carryforwards are used to offset
future capital gains, it is probable that the capital gains so offset will not
be distributed to shareholders.

NOTE 8 -- LINE OF CREDIT:

The Fund and certain affiliated funds maintain a line of credit of $160,000,000
with a syndicate of banks in order to secure a source of funds for temporary

NOTE 10 -- OTHER MATTERS:

NYLIM and mutual funds that NYLIM advises have received requests for information
from various government authorities and regulatory bodies regarding market
timing, late trading, operations, fees, expenses, and other matters. NYLIM and
the funds it advises are cooperating fully in responding to these requests. As
reported in response to those requests for information, NYLIM was previously
party to agreements with certain registered representatives of broker-dealers
relating to the level of trading by clients or customers of those registered
representatives in shares of certain funds of the Trust. NYLIM is continuing to
review what effect, if any, transactions under these agreements may have had on
the funds, and will continue to apprise the Board of Trustees of such
information. NYLIM does not believe at this time that such trading had any
material effect on the funds' financial statements or their shareholders. To
date, substantially all of the costs associated with these and other regulatory
matters have been borne by NYLIM. Except as described below, neither NYLIM nor
the funds advised by it have any reason to believe that they have been targeted
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.
Discussions have been held with the SEC concerning a possible resolution of this
matter. These discussions are continuing, but there can be no assurance at this
time as to the outcome of these efforts.

NOTE 11 -- CHANGE IN INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM (UNAUDITED):

On March 8, 2004, KPMG LLP ("KPMG") was selected as the Trust's independent
auditor for the 2004 fiscal year. The selection of KPMG was recommended by the
Trust's Audit Committee, comprised of all Non-Interested Trustees, and was
approved by the Trust's Board of Trustees.

The predecessor independent auditor's reports on the Trust's financial
statements for the period ended October 31, 2003 and year ended December 31,
2002 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 periods, and through the date of engagement of KPMG, there
were no disagreements between 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 periods.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Trustees and Shareholders of
The MainStay Funds:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of the MainStay Capital Appreciation Fund (the
"Fund"), one of the funds constituting The MainStay Funds, as of October 31,
2004, and the related statement of operations, statement of changes in net
assets and the financial highlights for the year or period then ended. These
financial statements and financial highlights are the responsibility of the
Fund's management. Our responsibility is to express an opinion on these
financial statements and financial highlights based on our audit. The statement
of changes in net assets for the period ended October 31, 2003 and the year
ended December 31, 2002, and the financial highlights for the periods presented
through October 31, 2003, were audited by other auditors, whose report dated
December 18, 2003 expressed an unqualified opinion thereon.

We conducted our audit in accordance with the Standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
also includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2004 by correspondence with the custodian and
brokers. As to securities purchased or sold but not yet received or delivered,
we performed other appropriate auditing procedures. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
MainStay Capital Appreciation Fund of The MainStay Funds as of October 31, 2004,
the results of its operations, the changes in its net assets and its financial
highlights for the year or period then ended, in conformity with U.S. generally
accepted accounting principles.

                    Annual Report
                    October 31, 2004


MESSAGE FROM
THE PRESIDENT

During the 12 months ended October 31, 2004, the U.S. stock market advanced, but
its pace and direction were by no means steady. Small- and mid-capitalization
stocks tended to outperform large-cap issues, and value stocks generally
outperformed growth stocks.

Economic activity, as measured by gross domestic product, increased from 4.2% in
the fourth quarter of 2003 to 4.5% in the first quarter of 2004. The pace of
economic growth slowed to 3.3% in the second quarter of 2004, and according to
preliminary estimates from the Bureau of Economic Analysis, gross domestic
product grew at a seasonally adjusted annual rate of 3.9% in the third quarter
of 2004.

Interest rates began the reporting period at a low 1.00%. In June 2004, the
Federal Open Market Committee responded to expanding output and improved labor
markets by raising the targeted federal funds rate by 25 basis points. Similar
moves in August and September brought the targeted federal funds rate to 1.75%.
In its September 2004 release, the Federal Open Market Committee affirmed its
belief that monetary policy remained accommodative.

Despite rising interest rates, bond markets generally advanced. High-yield bonds
and emerging-market debt were particularly strong. The U.S. dollar declined
relative to most other currencies, which helped U.S. exporters.

In pursuing its investment objective, each MainStay Fund consistently seeks to
apply a well-defined investment process in all market environments. We believe
that a consistent, disciplined investment approach can help investors make more
prudent and practical decisions regarding their investments.

In the report that follows, you'll find additional information about the market
forces, investment decisions, and individual securities that affected your
MainStay Fund during the 12 months ended October 31, 2004. We thank you for
investing with us, and we look forward to many years of continued service in
your behalf.

Sincerely,

/s/ GARY E. WENDLANDT

Gary E. Wendlandt
President

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

Questions answered by portfolio managers Edward Silverstein and Edmund C.
Spelman of MacKay Shields LLC

CAN YOU BRIEFLY DESCRIBE THE FUND'S INVESTMENT APPROACH?

The Fund invests primarily in convertible securities and may spread investments
across various types of securities issued by a variety of companies and
industries. The Fund invests in high-yield securities and may invest a portion
of its assets in nonconvertible debt securities, equity securities that do not
pay regular dividends, U.S. government securities, and cash or cash equivalents.
In implementing these strategies, attention may be given to the anticipated
return of the underlying common stock and the credit risk and projected interest
return of fixed-income securities. The premium for the convertible security
relative to the underlying common stock may also be considered. Securities may
be sold if economic, financial, credit, interest return, or other considerations
lead us to believe that the security will not contribute to meeting the Fund's
investment objective.

WHAT MAJOR FACTORS INFLUENCED THE MARKET FOR CONVERTIBLE BONDS DURING THE
12-MONTH REPORTING PERIOD?

Convertible bonds are hybrid instruments whose performance is derived from the
performance of the related equity and fixed-income markets. For the 12 months
ended October 31, 2004, the equity market, as measured by the S&P 500 Index(1)
rose 9.42%. Over the same period, the corporate bond market, as measured by the
Lehman Brothers Investment Grade Index,(2) rose 6.59%, and the Lehman Brothers
High Yield Index(3) rose 12.32%. The positive returns in these equity and
fixed-income markets drove the benchmark Credit Suisse First Boston(TM)
Convertible Securities Index(4) 7.51% higher for the 12 months ended October 31,
2004. During the reporting period, convertible-bond yield spreads relative to
Treasuries contracted 213 basis points, which also enhanced the performance of
convertible bonds.

HOW DID THE FUND PERFORM RELATIVE TO THE CONVERTIBLE MARKET AS A WHOLE?

Many of the best-performing names in the convertible market were speculative
issues such as Nortel, Yahoo!, Sepracor, Elan Pharmaceuticals, and Lucent. These
issues tend to offer unattractive equity-type risk/reward profiles, which
include full participation in the upside potential as well as full participation
on the downside. Since we tend to avoid securities with this profile, the Fund
underperformed the market as measured by the Credit Suisse First Boston(TM)
Convertible Securities Index. We prefer to invest in securities that may offer
substantial participation in the upside potential of the underlying common stock
with only moderate participation on the downside.

WHAT KEY FACTORS INFLUENCED FUND MANAGEMENT DECISIONS DURING THE REPORTING
PERIOD?

Two important factors were our outlook for specific industry groups and our
expectation that interest rates were likely to move higher. We structured the
portfolio so that any upward movement in interest rates would have a minimal
impact on the performance of the convertible bonds held by the Fund. We focused
on securities that were more sensitive to stock movements than to interest
rates. We also sought to reduce interest-rate sensitivity with bonds that have
relatively short-term maturities, floating-rate structures, put features, or a
combination of these characteristics.

HOW DID YOUR INDUSTRY OUTLOOK AFFECT THE FUND'S PERFORMANCE?

During the reporting period, we significantly overweighted the Fund's portfolio
in energy-related names, particularly in the energy equipment and services
industry. Companies in this industry have been indirect beneficiaries of high
energy prices as companies such as ExxonMobil have increased spending on
equipment and services. The Fund's overweighted position in the energy sector
enhanced Fund performance.

High-yield securities ("junk bonds") are generally considered speculative
because they present a greater risk of loss than higher- quality debt securities
and may be subject to greater price volatility.

   made directly into an index.

 6   MainStay Convertible Fund


Our unfavorable outlook for information technology led us to underweight this
sector. Unfortunately, the Fund maintained a market weighting in semiconductor
companies that provided weak performance. The Fund was also underweighted in
Internet companies, such as Yahoo!, which performed quite well.

We sold nearly all of the Fund's airline holdings on the belief that fuel prices
will remain high for the foreseeable future. We see downside potential in the
industry's financial duress, overcapacity, high labor costs, and low barriers to
entry. Although airline bonds generally underperformed, they improved slightly
when oil prices moved back from their recent high levels.

WHICH OF THE FUND'S SECURITIES WERE STRONG PERFORMERS DURING THE REPORTING
PERIOD?

The Fund's single-best performer in absolute dollar gain was oil services
company Halliburton. The Fund owned a combination of convertible bonds and
common stock in the company. The shares significantly outperformed the market as
Halliburton's oil services and equipment business revenue and profits exceeded
analyst's expectations. While spending increased on oil equipment and services,
Halliburton appears to have successfully negotiated a settlement in an asbestos
law suit. The settlement should allow the company to once again focus on its
core oil-equipment business.

The Fund's second-best performer was Tyco International. Now under a new
management team, the company has improved its profitability and cash flow. In
just one year, the company has gone from being overly leveraged to generating
significant free cash flow, which Tyco has used to retire debt and decrease
interest expense.

WERE THERE OTHER SOLID PERFORMERS?

Yes. Devon Energy, an exploration and production company, was a beneficiary of
higher energy prices. The company increased production to capitalize on the
trend. Transocean, which owns and leases offshore drilling rigs, saw
expectations improve when the company found customers willing to pay higher day
rates to lease Transocean's equipment. Fisher Scientific shares rose when the
company increased its earnings forecast after several acquisitions during the
year. Box manufacturer Smurfit-Stone Container saw its shares advance when
demand increased and the dollar's decline gave the company an advantage over
foreign competitors. Mandalay Resorts convertible bonds and shares performed
well when the company's newest hotel property, THE HOTEL, opened with high
occupancy rates. The company's share price climbed when Mandalay Resorts
accepted a takeover offer from MGM Mirage.

WHICH SECURITIES DETRACTED FROM THE FUND'S PERFORMANCE DURING THE REPORTING
PERIOD?

Teva Pharmaceutical took the greatest toll on the Fund's performance in absolute
dollar terms. The generic drug company's shares lost nearly nine percent of
their value over the 12-month period, despite successive earnings reports that
handily beat analysts' expectations. Teva was hurt by new competition and
concern about price erosion and disappointing earnings among competitors, even
though evidence of a problem at Teva Pharmaceutical has yet to emerge.

The second-worst performer during the 12-month period was Calpine, whose shares
and convertible bonds declined significantly when the company's electric-power
business was hurt by mild summer weather. Merck's common stock declined when
Vioxx was withdrawn from the market and law suits about the drug's side effects
became a concern. Cypress Semiconductor's shares fell when slowing sales and
rising inventories led to earnings disappointments.

WERE THERE OTHER WEAK PERFORMERS?

Yes. Delta Airlines and Alaska Air were both hurt by the rise in fuel costs and
by overcapacity in the airline industry that has forced carriers to continue
lowering prices to maintain passenger traffic.

WERE THERE ANY SIGNIFICANT SALES DURING THE REPORTING PERIOD?

The disposal of nearly all of the Fund's airline holdings was certainly
significant. We sold the Fund's positions in ASE Test and Beverly when the
shares reached their respective price targets and the stocks appeared to be
fully valued. Masco and Cendant were sold because Masco's home improvement
business and Cendant's real estate brokerage units, Century 21 and Coldwell
Banker, might suffer if interest rates rise substantially. We sold the Fund's
position in Mandalay Resorts when the takeover offer from MGM Mirage pushed the
stock to a level where we felt there was little remaining upside potential.

WERE THERE ANY SIGNIFICANT PURCHASES DURING THE REPORTING PERIOD?

We made several significant purchases for the Fund during the first six months
of 2004. We purchased Schlumberger, the world's largest provider of oilfield
services and equipment, to take advantage of higher

                                                     www.mainstayfunds.com     7


spending by exploration and production companies such as ExxonMobil and British
Petroleum. We purchased convertible bonds of Whole Foods Markets, a rapidly
growing retailer of organic produce and grocery items. As more Americans look to
improve their diets, Whole Foods is likely to see earnings continue to improve.
New stores and increasing sales-per-store are driving earnings increases.
Goodyear Tire is exiting unprofitable markets, such as original equipment tires,
and is cutting costs and improving its position in the more profitable
replacement-tire market. We believe the company's shares will move higher as the
market becomes aware of this turnaround story. We also added to the Fund's
position in industrial conglomerate Tyco International, which has seen its
bottom line improve as sales growth, cost cutting, and deleveraging have all
helped strengthen earnings. We also added to the Fund's small position in Sirius
Satellite Radio. With the signing of radio personality Howard Stern, Sirius
lifted its profile and increased demand for it satellite-radio service. We added
to the Fund's position in TXU. Under new management, the company has
significantly cut costs and has benefited from higher power prices in Texas, the
company's primary market for electric-utility services.

HOW HAVE THE FUND'S WEIGHTINGS CHANGED?

The Fund's benchmark is the CSFB Convertible Securities Index. As of October 31,
2004, the Fund was significantly overweighted relative to the benchmark in
energy (including oil service companies and exploration and production
companies). The Fund's information technology holdings were significantly
underweighted relative to the Index. The Fund was also overweighted relative to
the CSFB Convertible Securities Index in utilities.

WHAT IS YOUR OUTLOOK GOING FORWARD?

We remain cautiously optimistic. Following the undisputed conclusion of the
Presidential election, we believe that in the absence of any major domestic
terrorism, the equity markets have room to rally from their relative
tranquility. A successful conclusion to the fighting in Iraq would add to this
bullish sentiment. Several factors, however, might offset this positive outlook.
Energy prices remain high by recent historical standards. The American consumer
carries significant debt and access to additional credit might be jeopardized if
the real-estate market levels off or declines. On the other hand, the equity
markets are not overly enthusiastic and may move higher in the absence of major
negative economic or political news.

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

NOTES TO FINANCIAL STATEMENTS

NOTE 1 -- ORGANIZATION AND BUSINESS:

The MainStay Funds (the "Trust") was organized on January 9, 1986 as a
Massachusetts business trust. The Trust is registered under the Investment
Company Act of 1940, as amended (the "1940 Act"), as an open-end management
investment company and comprises twenty-two funds (collectively referred to as
the "Funds"). These financial statements and notes relate only to MainStay
Convertible Fund (the "Fund"), a diversified fund.

The Fund currently offers three classes of shares. Class A shares, whose
distribution commenced on January 3, 1995, 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 within one year of purchase of Class C
shares. Distribution of Class B shares and Class C shares commenced on May 1,
1986 and September 1, 1998, respectively. Class A shares, Class B shares and
Class C shares bear the same voting (except for issues that relate solely to one
class), dividend, liquidation and other rights and conditions except that the
Class B shares and Class C shares are subject to higher distribution fee rates.
Each class of shares bears distribution and/or service fee payments under a
distribution plan pursuant to Rule 12b-1 under the 1940 Act.

The Fund's investment objective is to seek capital appreciation together with
current income.

The Fund's principal investments include high yield securities (sometimes called
"junk bonds"), which are generally considered speculative because they present a
greater risk of loss, including default, than higher quality debt securities.
These securities pay a premium -- a high interest rate or yield -- because of
the increased risk of loss. These securities can also be subject to greater
price volatility.

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

NOTE 2 -- SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with generally accepted
accounting principles and follows the significant accounting policies described
below.

(A) SECURITIES VALUATION.  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 New York Stock Exchange. 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. Options contracts are valued at
the last posted settlement price on the market where such options are
principally traded. Temporary cash investments acquired over 60 days 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.
Securities for which market quotations are not readily available are valued by
methods deemed by the Board of Trustees to represent fair value. Reasons for
which securities may be valued in this manner include, but are not limited to,
trading for a security has been halted or suspended, a security has been
de-listed from a national exchange, or trading on a security's primary market is
temporarily closed at a time when under normal conditions it would be open. The
Fund held securities with a value of $38,042 that were valued in such manner.

Certain events may occur between the time that foreign markets close, on which
securities held by the Fund principally trade, and the time at which the Fund's
NAV is calculated. These events may include, but are not limited to, situations
relating to a single issue in a market sector, significant fluctuations in U.S.
or foreign markets, natural disasters, armed conflicts, governmental actions or
other developments not tied directly to the securities markets. Should the
Manager or Subadvisor conclude that such events may have effected the accuracy
of the last price reported on the local foreign market, the Manager or
Subadvisor may, pursuant to procedures adopted by the Fund, adjust the value of
the local price to reflect the impact on the price of such securities as a
result of such events.

(B) FOREIGN CURRENCY FORWARD CONTRACTS.  A foreign currency forward contract is
an agreement to buy or sell currencies of different countries on a specified
future

 20   MainStay Convertible Fund


date at a specified rate. During the period the forward contract is open,
changes in the value of the contract are recognized as unrealized gains or
losses by "marking to market" such contract on a daily basis to reflect the
market value of the contract at the end of each day's trading. When the forward
contract is closed, the Fund records a realized gain or loss equal to the
difference between the proceeds from (or cost of) the closing transaction and
the Fund's basis in the contract. The Fund enters into foreign currency forward
contracts primarily to hedge its foreign currency denominated investments and
receivables and payables against adverse movements in future foreign exchange
rates.

The use of foreign currency forward contracts involves, to varying degrees,
elements of market risk in excess of the amount recognized in the Statement of
Assets and Liabilities. The contract amount reflects the extent of the Fund's
involvement in these financial instruments. Risks arise from the possible
movements in the foreign exchange rates underlying these instruments. The
unrealized appreciation on forward contracts reflects the Fund's exposure at
period end to credit loss in the event of a counterparty's failure to perform
its obligations.

(C) PURCHASED AND WRITTEN OPTIONS.  The Fund may write covered call and put
options on its 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 cancelled in closing purchase
transactions are added to the proceeds or netted against the amount paid on the
transaction to determine the realized gain or loss. By writing a covered call
option, the Fund foregoes in exchange for the premium 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, the Fund, in exchange for the premium, accepts the risk of a decline in
the market value of the underlying security or foreign currency below the
exercise price. A call option may be covered by the call writer's owning the
underlying security throughout the option period. A call option may also be
covered by the call writer's maintaining liquid assets valued at greater than
the exercise price of the call written, in a segregated account with its
custodian.

The Fund may purchase call and put options on its portfolio securities. The Fund
may purchase call options to protect against an increase in the price of the
security it anticipates purchasing. The Fund may purchase put options on its
securities to protect against a decline in the value of the security or to close
out covered written put positions. The Fund may also purchase options to seek to
enhance returns. Risks may arise from an imperfect correlation between the
change in market value of the securities held by the Fund and the prices of
options relating to the securities 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.

(D) RESTRICTED SECURITIES.  A restricted security is a security which has been
purchased through a private offering and cannot be resold to the general public
without prior registration under the Securities Act of 1933. Disposal of these
securities may involve time-consuming negotiations and expenses and prompt sale
at an acceptable price may be difficult.

(E) SECURITIES LENDING.  The Fund may lend its securities to broker-dealers and
financial institutions. The loans are collateralized by cash or securities at
least equal at all times to the market value of the securities loaned. The Fund
may bear the risk of delay in recovery of, or loss of rights in, the securities
loaned should the borrower of the securities experience financial difficulty.
The Fund receives compensation for lending its securities in the form of fees or
it retains a portion of interest on the investment of any cash received as
collateral. The Fund also continues to receive interest and dividends on the
securities loaned and any gain or loss in the market price of the securities
loaned that may occur during the term of the loan will be for the account of the
Fund. (See Note 7.)

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

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

(G) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS.  Dividends and distributions
are recorded on the ex-dividend date. The Fund intends to declare and pay
dividends quarterly and capital gain distributions, if any, annually. 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.

The following table discloses the current year reclassifications between
accumulated distributions in excess of net investment income, accumulated net
realized loss on investments, and additional paid-in capital arising from

                                                    www.mainstayfunds.com     21

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

permanent differences; net assets at October 31, 2004, are not effected.

   $115,757       $21,728         $(137,485)
- ----------------------------------------------
</Table>

The reclassifications for the Fund are primarily due to premium amortization
adjustments, real estate Investment trusts gain (loss), and taxable over
distributions of dividends.

(H) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  The Fund records security
transactions on the trade date. Realized gains and losses on security
transactions are determined using the identified cost method. Dividend income is
recognized on the ex-dividend date and interest income is accrued as earned.
Discounts and premiums on securities, other than short-term securities,
purchased for the Fund 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. Income from payment-in-kind securities is recorded
daily based on the effective interest method of accrual.

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

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

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

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

The assets and liabilities are presented at the exchange rates and market values
at the close of the period. The realized and unrealized changes in net assets
arising from fluctuations in exchange rates and market prices of securities are
not separately presented. Accordingly, gains and losses from foreign currency
transactions are included in the reported net realized gain (loss) on investment
transactions.

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

(J) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred except where direct allocations of expenses can be made. Expenses
(other than expenses incurred under the distribution plans) are allocated to
separate classes of shares based upon their relative net asset value on the date
the expenses are incurred. The expenses borne by the Fund, including those of
related parties to the Fund, are shown in the Statement of Operations.

(K) 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.

NOTE 3 -- FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER AND SUBADVISOR.  New York Life Investment Management LLC ("NYLIM" or
the "Manager"), an indirect wholly-owned subsidiary of New York Life Insurance
Company ("New York Life"), serves as the Fund's manager. The Manager provides
offices, conducts clerical, recordkeeping and bookkeeping services, and keeps
the financial and accounting records required for the Fund. The Manager also
pays the salaries and expenses of all personnel affiliated with the Fund and all
the operational expenses that are not the responsibility of the Fund. MacKay
Shields LLC (the "Subadvisor"), a registered investment advisor and indirect
wholly-owned subsidiary of New York Life, is responsible for the day-to-day
portfolio management of the Fund.

Through July 31, 2004, the Trust, on behalf of the Fund, paid the Manager a
monthly fee for services performed and the facilities furnished at an annual
rate of 0.72% of the Fund's average daily net assets on assets up to $500
million, 0.67% on assets from $500 million to $1 billion and 0.62% on assets in
excess of $1 billion. Effective as of August 1, 2004, NYLIM has voluntarily
agreed to waive its management fee by 0.05% of the Fund's average net assets. In
addition, effective December 1, 2004, NYLIM has voluntarily agreed to reimburse
the

 22   MainStay Convertible Fund


expenses of the Fund to the extent that operating expenses would exceed on an
annualized basis 1.20%, 1.95% and 1.95% of the average daily net assets of the
Class A, Class B and Class C shares, respectively. For the year ended October
31, 2004, the Manager earned from the Fund $4,224,831 and waived $70,554 of its
fee.

Pursuant to the terms of a Sub-Advisory Agreement between NYLIM and MacKay
Shields, the Manager paid the Subadvisor a monthly fee of 0.36% of the Fund's
average daily net assets on assets up to $500 million, 0.335% on assets from
$500 million to $1 billion and 0.31% on assets in excess of $1 billion. To the
extent the Manager has agreed to reimburse expenses of the Fund, the Subadvisor
has voluntarily agreed to do so proportionately.

(B) DISTRIBUTION AND SERVICE FEES.  The Trust, on behalf of the Fund, has a
Distribution Agreement with NYLIFE Distributors LLC. (the "Distributor"), an
indirect wholly-owned subsidiary of New York Life. The Fund, with respect to
each class of shares, has adopted distribution plans (the "Plans") in accordance
with the provisions of Rule 12b-1 under the 1940 Act. Pursuant to the Class A
Plan, the Distributor receives a monthly fee from the Fund at an annual rate of
0.25% of the average daily net assets of the Fund's Class A shares, which is an
expense of the Class A shares of the Fund for distribution or service activities
as designated by the Distributor. Pursuant to the Class B and Class C Plans, the
Fund pays the Distributor a monthly fee, which is an expense of the Class B and
Class C shares of the Fund, at the annual rate of 0.75% of the average daily net
assets of the Fund's Class B and Class C shares. The Distribution Plans provide
that the Class B and Class C shares of the Fund 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 Fund. The Plans provide that the distribution and service
fees are payable to the Distributor regardless of the amounts actually expended
by the Distributor for distribution of the Fund's shares and service activities.

(C) SALES CHARGES.  The Fund was advised by the Distributor that the amount of
sales charges retained on sales of Class A shares was $61,320 for the year ended
October 31, 2004. The Fund was also advised that the Distributor retained
contingent deferred sales charges on redemptions of Class A, Class B and Class C
shares of $4,552, $286,029 and $7,162, respectively, for the year ended October
31, 2004.

(D) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT.  NYLIM
Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's
transfer, dividend disbursing and shareholder servicing agent. NYLIM Service has
entered into an agreement with Boston Financial Data Services ("BFDS") pursuant
to which BFDS will perform certain of the services for which NYLIM Service is
responsible. Transfer agent expenses for the year ended October 31, 2004,
amounted to $1,774,301.

(E) NON-INTERESTED TRUSTEES.  Non-Interested Trustees are paid an annual
retainer fee of $45,000, $2,000 for each Board meeting, $1,000 for each
Committee meeting and $500 for each Valuation Subcommittee telephonic meeting
attended plus reimbursement for travel and out-of-pocket expenses. The Lead
Non-Interested Trustee is also paid an annual retainer fee of $20,000. The Audit
Committee Chairman receives an additional $2,000 for each meeting of the Audit
Committee attended and the Chairpersons of the Brokerage Committee, Operations
Committee and Performance Committee each receive an additional $1,000 for each
meeting of the Brokerage Committee, Operations Committee and Performance
Committee attended, respectively. In addition, each Non-Interested Trustee is
paid $1,000 for attending meetings of the Non-Interested Trustees held in
advance of or in connection with Board/Committee meetings. The Trust allocates
trustees fees in proportion to the net assets of the respective Funds. Thus the
Convertible Fund only pays a portion of the fees identified above.

(F) OTHER.  Fees for the cost of legal services, included in Professional fees
as shown on the Statement of Operations, provided to the Fund by the Office of
the General Counsel of NYLIM amounted to $17,477 for the year ended October 31,
2004.

The Fund pays the Manager a monthly fee for recordkeeping services provided
under the Accounting Agreement at the annual rate of 1/20 of 1% for the first
$20 million of average monthly net assets, 1/30 of 1% of the next $80 million of
average monthly net assets and 1/100 of 1% of any amount in excess of $100
million of average monthly net assets. Fees for recordkeeping services provided
to the Fund by the Manager amounted to $85,991 for the year ended October 31,
2004.

NOTE 4 -- CUSTODIAN:

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

NOTE 5 -- FEDERAL INCOME TAX:

As of October 31, 2004, the components of accumulated loss on a tax basis were
as follows:

<Table>
<Caption>
  ACCUMULATED CAPITAL    UNREALIZED   TOTAL ACCUMULATED
   AND OTHER LOSSES     APPRECIATION        LOSS

The difference between book-basis and tax-basis unrealized appreciation is
primarily due to wash sale deferrals.

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

At October 31, 2004, for federal income tax purposes, capital loss carryforwards
of $85,597,773 were available as shown in the table below, to the extent
provided by the regulations to offset future realized gains of the Fund through
the years indicated. 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 6 -- PURCHASES AND SALES OF SECURITIES (IN 000'S):
During the year ended October 31, 2004, purchases and sales of securities, other
than short-term securities, were $551,207 and $622,868, respectively.

NOTE 7 -- PORTFOLIO SECURITIES LOANED:

As of October 31, 2004, the Fund had securities on loan with an aggregate market
value of $94,751,864. The Fund received $106,411,125 in cash as collateral for
securities on loan which was used to purchase highly liquid short-term
investments in accordance with the Fund's securities lending procedures.
Pursuant to Rule 2a-7, securities purchased with collateral received are valued
at amortized cost.

NOTE 8 -- LINE OF CREDIT:

The Fund and certain affiliated funds maintain a line of credit of $160,000,000
with a syndicate of banks in order to secure a source of funds for temporary
purposes to meet unanticipated or excessive shareholder redemption requests. The
funds pay a commitment fee, at an annual rate of .075% of the average commitment
amount, regardless of usage, to The Bank of New York, which acts as agent to the
syndicate. Such commitment fees are allocated among the funds based upon net
assets and other factors. Interest on any revolving credit loan is charged based
upon the Federal Funds Advances rate. There were no borrowings on the line of
credit during the year ended October 31, 2004.

NOTE 10 -- OTHER MATTERS:

NYLIM and mutual funds that NYLIM advises have received requests for information
from various government authorities and regulatory bodies regarding market
timing, late trading, operations, fees, expenses, and other matters. NYLIM and
the funds it advises are cooperating fully in responding to these requests. As
reported in response to those requests for information, NYLIM was previously
party

 24   MainStay Convertible Fund


to agreements with certain registered representatives of broker-dealers relating
to the level of trading by clients or customers of those registered
representatives in shares of certain funds of the Trust. NYLIM is continuing to
review what effect, if any, transactions under these agreements may have had on
the funds, and will continue to apprise the Board of Trustees of such
information. NYLIM does not believe at this time that such trading had any
material effect on the funds' financial statements or their shareholders. To
date, substantially all of the costs associated with these and other regulatory
matters have been borne by NYLIM. Except as described below, neither NYLIM nor
the funds advised by it have any reason to believe that they have been targeted
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.
Discussions have been held with the SEC concerning a possible resolution of this
matter. These discussions are continuing, but there can be no assurance at this
time as to the outcome of these efforts.

NOTE 11 -- CHANGE IN INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM (UNAUDITED):

On March 8, 2004, KPMG LLP ("KPMG") was selected as the Trust's independent
auditor for the 2004 fiscal year. The selection of KPMG was recommended by the
Trust's Audit Committee, comprised of all Non-Interested Trustees, and was
approved by the Trust's Board of Trustees.

The predecessor independent auditor's reports on the Trust's financial
statements for the period ended October 31, 2003 and year ended December 31,
2002 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 periods, and through the date of engagement of KPMG, there
were no disagreements between 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 periods.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Trustees and Shareholders of
The MainStay Funds:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of the MainStay Convertible Fund (the "Fund"), one
of the funds constituting The MainStay Funds, as of October 31, 2004, and the
related statement of operations, statement of changes in net assets and the
financial highlights for the year then ended. These financial statements and
financial highlights are the responsibility of the Fund's management. Our
responsibility is to express an opinion on these financial statements and
financial highlights based on our audit. The statement of changes in net assets
for the period ended October 31, 2003 and the year ended December 31, 2002, and
the financial highlights for the periods presented through October 31, 2003,
were audited by other auditors, whose report dated December 18, 2003 expressed
an unqualified opinion thereon.

We conducted our audit in accordance with the Standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
also includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2004 by correspondence with the custodian and
brokers. As to securities purchased or sold but not yet received or delivered,
we performed other appropriate auditing procedures. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
MainStay Convertible Fund of The MainStay Funds as of October 31, 2004, the
results of its operations, the changes in its net assets and its financial
highlights for the year then ended, in conformity with U.S. generally accepted
accounting principles.

MESSAGE FROM
THE PRESIDENT

During the 12 months ended October 31, 2004, the U.S. stock market advanced, but
its pace and direction were by no means steady. Small- and mid-capitalization
stocks tended to outperform large-cap issues, and value stocks generally
outperformed growth stocks.

Economic activity, as measured by gross domestic product, increased from 4.2% in
the fourth quarter of 2003 to 4.5% in the first quarter of 2004. The pace of
economic growth slowed to 3.3% in the second quar-
ter of 2004, and according to preliminary estimates from the Bureau of Economic
Analysis, gross domestic product grew at a seasonally adjusted annual rate of
3.9% in the third quarter of 2004.

Interest rates began the reporting period at a low 1.00%. In June 2004, the
Federal Open Market Committee responded to expanding output and improved labor
markets by raising the targeted federal funds rate by 25 basis points. Similar
moves in August and September brought the targeted federal funds rate to 1.75%.
In its September 2004 release, the Federal Open Market Committee affirmed its
belief that monetary policy remained accommodative.

Despite rising interest rates, bond markets generally advanced. High-yield bonds
and emerging-market debt were particularly strong. The U.S. dollar declined
relative to most other currencies, which helped U.S. exporters.

In pursuing its investment objective, each MainStay Fund consistently seeks to
apply a well-defined investment process in all market environments. We believe
that a consistent, disciplined investment approach can help investors make more
prudent and practical decisions regarding their investments.

In the report that follows, you'll find additional information about the market
forces, investment decisions, and individual securities that affected your
MainStay Fund during the 12 months ended October 31, 2004. We thank you for
investing with us, and we look forward to many years of continued service in
your behalf.

Sincerely,

/s/ GARY E. WENDLANDT

Gary E. Wendlandt
President

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 graph assumes an initial investment of $10,000 and reflects 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%.

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

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 data 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

CAN YOU BRIEFLY DESCRIBE THE FUND'S INVESTMENT APPROACH?

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

WHAT WERE THE MAJOR FACTORS THAT AFFECTED THE STOCK MARKET DURING THE 12-MONTH
REPORTING PERIOD?

The reporting period began amid changing investor sentiment. Concerns about the
economy gave way to optimism that a sustainable recovery might be underway.
Several factors helped support the economy, including the lowest interest rates
seen in 45 years and a generous tax-cut package. The weaker dollar helped
stimulate export activity, and low inventory levels prompted additional business
investment.

Investors, however, were not able to sustain the strong stock-market gains
posted in the fourth quarter of 2003. Although stocks did surge into early
February 2004, the latter part of February and much of March proved troublesome
for the equity market. Terrorism muted any momentum that had been building in
the markets when an attack in Madrid, combined with the assassination of Hamas
leader Sheik Ahmed Yasin, drove equities lower. Ongoing violence in Iraq--not
only against U.S. troops but also against civilians working to rebuild Iraq's
infrastructure--further troubled the financial markets. Instability in the
Middle East and geopolitical difficulties in other areas continued to present
obstacles for equity investors.

Caution was a market theme in the second and third quarters of 2004.
Record-breaking oil prices increased the threat of inflation. Meanwhile,
investors seemed preoccupied with the uncertainty surrounding the November
presidential election. The Federal Open Market Committee raised the targeted
federal funds rate 25 basis points three times during the reporting period--in
June, August, and September. Even so, the Federal Reserve remained optimistic
that the economy could weather the "soft patch" brought on by high energy prices
and other forces.

WHAT WERE THE BEST-PERFORMING SUBINDUSTRIES(2) IN THE S&P 500(R) INDEX DURING
THE REPORTING PERIOD?

On the basis of total returns alone, Internet retail (+74.49%)(3) was the
best-performing subindustry for the 12 months ended October 31, 2004. Other top-
performing subindustries included fertilizers & agricultural chemicals
(+70.66%), oil & gas refining, marketing & transportation (+68.00%), Internet
software & services (+65.63), and wireless telecommunication services (+59.51%).

The subindustries that made the greatest positive contribution to the
performance of the Index, however, all had higher weightings and lower total
returns. On the basis of impact, which takes weightings and total returns both
into consideration, the leading subindustry was integrated oil & gas (+38.52%),
followed by industrial conglomerates (+18.38%), diversified banks (+13.99%),
electrical utilities (+22.03%), and aerospace & defense (+18.56%).

WHICH SUBINDUSTRIES WERE THE WORST PERFORMERS?

On the basis of total returns alone, the worst-performing subindustries in the
index for the 12-month reporting period were IT consulting & other services
(-30.86%), semiconductor equipment (-29.57%), insurance brokers (-28.61%),
semiconductors (-24.29%), and airlines (-22.46%).

For the 12 months ended October 31, 2004, semiconductors (-24.29%) was the
subindustry with the greatest negative impact on Index performance when
weightings and total returns were both taken into account. Pharmaceuticals
(-5.68%) was next, followed by semiconductor equipment (-29.57%),

Index funds generally seek to reflect the performance of an index or an
allocation among indices, unlike other funds, whose objectives may, in some
cases, involve seeking to outperform an index or other benchmark. The Fund may
invest in derivatives, which may increase the volatility of the Fund's net asset
value and may result in a loss to the Fund.

2. The Global Industry Classification Standard categorizes companies by sector,
   industry group, industry, and subindustry. Results in this section of the
   annual report reflect subindustry and company performance. In the Portfolio
   of Investments that follows, companies are listed by industry.
3. Percentages reflect the total-return performance, including reinvestment of
   all dividends and capital gains, of the subindustries or the securities
   mentioned for the 12 months ended 10/31/04. Due to purchases and sales, the
   performance of Fund holdings may differ from that of the sub-industries or
   securities themselves.

hypermarkets & super centers (-5.88%), and broadcast & cable TV (-13.76%).

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

For the 12 months ended October 31, 2004, the best-performing company in the S&P
500(R) Index on the basis of total returns alone was Autodesk (+174.03%). The
second-best performer was TXU (+168.27%), followed by Apple Computer (+129.49%),
Allegheny Technology (+119.74%), and Valero Energy (+101.26%).

As impressive as these returns may be, the five stocks that made the greatest
positive contribution to the performance of the S&P 500(R) Index all had higher
weightings and lower total returns. On the basis of impact which takes
weightings and total returns both into account, the strongest positive
contributor to the performance of the Index for the 12-month period was
ExxonMobil (+34.55%), followed by General Electric (+17.61%), ChevronTexaco
(+42.83%), QUALCOMM (+76.04%), and eBay (+74.49%).

WHICH STOCKS WERE THE WEAKEST PERFORMERS DURING THE REPORTING PERIOD?

On the basis of total returns alone, the worst-performing stock in the S&P
500(R) during the 12 months ended October 31, 2004, was Ciena (-61.47%). Other
weak performers included Delta Airlines (-58.14%), Winn-Dixie Stores (-57.48%),
LSI Logic (-50.76%), and Calpine (-45.99%).

On an impact basis, which takes weightings and total returns both into account,
Intel (-32.65%) made the greatest negative contribution to the performance of
the Index for the 12-month reporting period. Merck (-29.24%) was next, followed
by Wal-Mart Stores (-8.53%), Pfizer (-8.39%), and Citigroup (-6.39%).

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

The Fund seeks to track the performance and weight-
ings 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 fiscal year
ended October 31, 2004, there were 13 companies deleted from the S&P 500(R)
Index and 13 companies added to it. Among the deleted companies were familiar
names such as Tupperware, American Greetings, John Hancock Financial Services,
and AT&T Wireless. Among the additions were such well-known companies as
Caremark Rx, E*TRADE Financial, Valero Energy, and Coach.

WHAT DO YOU ANTICIPATE GOING FORWARD?

After the reporting period ended, President Bush was reelected, which served as
a short-term catalyst for a surge in the equity markets. In our opinion,
however, it remains to be seen whether the direction of oil prices and
inflation--and their effects on corporate profits--will quell some of the
market's anxieties or exacerbate them.

statements.


NOTES TO FINANCIAL STATEMENTS

NOTE 1 -- ORGANIZATION AND BUSINESS:

The MainStay Funds (the "Trust") was organized on January 9, 1986 as a
Massachusetts business trust. The Trust is registered under the Investment
Company Act of 1940, as amended (the "1940 Act"), as an open-end management
investment company and comprises twenty-two funds (collectively referred to as
the "Funds"). These financial statements and notes relate only to MainStay
Equity Index Fund (the "Fund"). The Board of Trustees of the Trust approved the
closure of the Fund to new share purchases effective January 1, 2002. Existing
shareholders may continue to maintain share positions held in the Fund, elect or
continue to reinvest distributions, and NYLIFE LLC will continue to honor the
unconditional guarantee associated with the Fund (see Note 8).

The Fund's investment objective is to seek to provide investment results that
correspond to the total return performance (and reflect reinvestment of
dividends) of publicly traded common stocks represented by the Standard & Poor's
500 Composite Stock Price Index. MainStay Equity Index Fund is
"non-diversified," which means that it may invest a greater percentage of its
assets than diversified funds in a particular issuer. This may make it more
susceptible than diversified funds to risks associated with an individual
issuer, and to single economic, political or regulatory occurrences.

NOTE 2 -- SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with generally accepted
accounting principles and follows the significant accounting policies described
below.

(A) SECURITIES VALUATION.  Equity securities are valued at the latest quoted
sales prices as of the close of 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. Futures contracts are valued at the last posted settlement price on the
market where such futures 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. Securities for which market
quotations are not readily available are valued by methods deemed by the Board
of Trustees to represent fair value. Reasons for which securities may be valued
in this manner include, but are not limited to, trading for a security has been
halted or suspended, a security has been de-listed from a national exchange, or
trading on a security's primary market is temporarily closed at a time when
under normal conditions it would be open. The Fund did not hold securities at
October 31, 2004, that were valued in such manner.

(B) 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. During the period the futures contract is open, changes in the value of
the contract are recognized as unrealized gains or losses by "marking to market"
such contract on a daily basis to reflect the market value of the contract at
the end of each day's trading. The Fund agrees to receive from or pay to the
broker an amount of cash equal to the daily fluctuation in the value of the
contract. Such receipts or payments are known as "variation margin". When the
futures contract is closed, the Fund records a realized gain or loss equal to
the difference between the proceeds from (or cost of) the closing transaction
and the Fund's basis in the contract. The Fund invests in stock index futures
contracts to gain full exposure to changes in stock market prices to fulfill its
investment objective.

The use of futures contracts involves, to varying degrees, elements of market
risk in excess of the amount recognized in the Statement of Assets and
Liabilities. The contract or notional amounts and variation margin reflect the
extent of the Fund's involvement in open futures positions. Risks arise from the
possible imperfect correlation in movements in the price of futures contracts,
interest rates and the underlying hedged assets, and the possible inability of
counterparties to meet the terms of their contracts. However, the Fund's
activities in futures contracts are conducted through regulated exchanges which
minimize counterparty credit risks.

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

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

(D) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are
recorded on the ex-dividend date. The Fund intends to declare and pay dividends
and capital gain distributions annually. 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

                                                    www.mainstayfunds.com     21

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

treatment; temporary differences do not require reclassification.

The following table discloses the current period reclassification between
accumulated undistributed net investment income and accumulated net realized
loss on investments arising from permanent differences; net assets at October
31, 2004, are not affected.

<Table>
<Caption>
  ACCUMULATED UNDISTRIBUTED   ACCUMULATED NET REALIZED
    NET INVESTMENT INCOME       LOSS ON INVESTMENTS
                           
         $(74,372)                       $74,372
</Table>

The reclassification for the Fund is due to real estate investment trust
distributions.

The Fund declared a dividend of $0.1277 per share which was paid on December 18,
2003, and also underwent a reverse share split on that day. The reverse share
split rate was 0.9965 per share outstanding calculated on fund shares
outstanding immediately after reinvestment of dividends.

Certain amounts in the Financial Highlights and Notes to Financial Statements
(see Note 8) have been adjusted to reflect the cumulative effects of this
reverse stock split, those that occurred in each of the periods presented, and
the reverse stock split that occurred subsequent to October 31, 2004 (see Note
11).

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

(F) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds where the expenses are
incurred except when direct allocations of expenses can be made. Expenses (other
than expenses incurred under the distribution plans) are allocated to separate
classes of shares based upon their relative net asset value on the date the
expenses are incurred. The expenses borne by the Fund, including those of
related parties to the Fund, are shown in the Statement of Operations.

(G) USE OF ESTIMATES.  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.

NOTE 3 -- FEES AND RELATED PARTY TRANSACTIONS:

Expenses borne by the Fund, which are paid to related parties to the Fund, are
included among the fees and expenses set forth in the Prospectus at page 21 in
the table "Fees and Expenses of the Fund", shown in the Statement of Operations,
and described below:

(A) MANAGER.  New York Life Investment Management LLC ("NYLIM" or the
"Manager"), an indirect wholly-owned subsidiary of New York Life Insurance
Company ("New York Life"), serves as the Fund's manager. The Manager provides
offices, conducts clerical, recordkeeping and bookkeeping services, and keeps
the financial and accounting records required for the Fund. The Manager also
pays the salaries and expenses of all personnel affiliated with the Fund and all
the operational expenses that are not the responsibility of the Fund. The Fund
is advised by the Manager directly, without a Subadviser.

The Trust, on behalf of the Fund, paid the Manager a monthly fee for services
performed and the facilities furnished at an annual rate of 0.50% of the Fund's
average daily net assets. Effective as of August 1, 2004, NYLIM has voluntarily
agreed to waive its management fee by 0.25% of the Fund's average net assets and
voluntarily agreed to limit the total operating expenses of the Fund to 0.80%.
For the year ended October 31, 2004, the Manager earned from the Fund $3,193,709
and waived $381,648 of its fee.

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

Pursuant to the Plan, the Distributor receives payments from the Fund at an
annual rate of 0.25% of the Fund's average daily net assets, which is an expense
of the Fund for distribution or service activities as designated by the
Distributor.

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

(C) SALES CHARGE.  The Fund was advised that the amount of sales charges
retained by the Distributor was $48 for the year ended October 31, 2004. The
Fund was also advised that the Distributor retained contingent deferred sales
charges on redemption of Class A shares of $10,524 for the year ended October
31, 2004.

(D) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT.  NYLIM
Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's
transfer, dividend disbursing and shareholder servicing

 22   MainStay Equity Index Fund


agent. NYLIM Service has entered into an agreement with Boston Financial Data
Services ("BFDS") pursuant to which BFDS will perform certain of the services
for which NYLIM Service is responsible. Transfer agent expenses for the year
ended October 31, 2004, amounted to $1,156,762.

(E) NON-INTERESTED TRUSTEES FEES.  Non-Interested Trustees are paid an annual
retainer fee of $45,000, $2,000 for each Board meeting, $1,000 for each
Committee meeting and $500 for each Valuation Subcommittee telephonic meeting
attended plus reimbursement for travel and out-of-pocket expenses. The Lead
Non-Interested Trustee is also paid an annual retainer fee of $20,000. The Audit
Committee Chairman receives an additional $2,000 for each meeting of the Audit
Committee attended and the Chairpersons of the Brokerage Committee, Operations
Committee and Performance Committee each receive an additional $1,000 for each
meeting of the Brokerage Committee, Operations Committee and Performance
Committee attended, respectively. In addition, each Non-Interested Trustee is
paid $1,000 for attending meetings of the Non-Interested Trustees held in
advance of or in connection with Board/Committee meetings. The Trust allocates
trustees fees in proportion to the net assets of the respective Funds. Thus the
Equity Index Fund only pays a portion of the fees identified above.

(F) OTHER.  Fees for the cost of legal services, included in Professional fees
as shown in the Statement of Operations, provided to the Fund by the Office of
the General Counsel of NYLIM amounted to $18,862 for the year ended October 31,
2004.

The Fund pays the Manager a monthly fee for recordkeeping services provided
under the Accounting Agreement at the annual rate of 1/20 of 1% for the first
$20 million of average monthly net assets, 1/30 of 1% of the next $80 million of
average monthly net assets and 1/100 of 1% of any amount in excess of $100
million of average monthly net assets. Fees for recordkeeping services provided
to the Fund by the Manager amounted to $90,540 for the year ended October 31,
2004.

NOTE 4 -- CUSTODIAN:

The Bank of New York is custodian of cash and securities of the Fund. Custodial
fees are charged the Fund based on market value of the securities and the number
of certain cash transactions incurred by the Fund.

NOTE 5 -- FEDERAL INCOME TAX:

At November 30, 2003, the Fund's year end for federal income tax purposes, the
components of accumulated loss on a tax basis were as follows:

<Table>
<Caption>
  UNDISTRIBUTED     ACCUMULATED                       TOTAL
     ORDINARY       CAPITAL AND     UNREALIZED     ACCUMULATED
      INCOME       OTHER LOSSES    DEPRECIATION        LOSS
                                         
    $2,285,251     $(119,052,229)  $91,126,781     $(25,640,197)
</Table>

The difference between book-basis and tax-basis unrealized depreciation is due
to wash sale deferrals real estate investment trust distributions and
mark-to-market of futures contracts.

At November 30, 2004, for federal income tax purposes, capital loss
carryforwards of $119,052,229 were available, to the extent provided by the
regulations, to offset future realized gains through 2011. 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 10 -- GUARANTEE:

NYLIFE LLC ("NYLIFE"), a wholly-owned subsidiary of New York Life, will
guarantee unconditionally and irrevocably pursuant to a Guaranty Agreement
between NYLIFE and the Equity Index Fund (the "Guarantee") that if, on the
business day immediately after ten years from the date of purchase (the
"Guarantee Date"), the net asset value ("NAV") of a Fund share plus the value of
all dividends and distributions paid, including cumulative reinvested dividends
and distributions attributable to such share paid during that ten-year period
("Guaranteed Share"), is less than the price initially paid for the Fund share
("Guaranteed Amount"), NYLIFE will pay shareholders an amount equal to the
difference between the Guaranteed Amount for each such share and the net asset
value of each such Guaranteed Share outstanding and held by shareholders as of
the close of business on the Guarantee Date. For the services that NYLIM and its
affiliates provide to the Fund, they receive the fees described in the
prospectus. Neither NYLIM nor its affiliates receive a separate fee for
providing the Guarantee, although the Guarantee has been considered in
connection with the annual renewal of the management fee. (See Notes 3 and 9.)

NOTE 11 -- OTHER MATTERS:

NYLIM and mutual funds that NYLIM advises have received requests for information
from various government authorities and regulatory bodies regarding market
timing, late trading, operations, fees, expenses, and other matters. NYLIM and
the funds it advises are cooperating fully in responding to these requests. As
reported in response to those requests for information, NYLIM was previously
party to agreements with certain registered representatives of broker-dealers
relating to the level of trading by clients or customers of those registered
representatives in shares of certain funds of the Trust. NYLIM is continuing to
review what effect, if any, transactions under these agreements may have had on
the funds, and will continue to apprise the Board of Trustees of such
information. NYLIM does not believe at this time that such trading had any
material effect on the funds' financial statements or their shareholders. To
date, substantially all of the costs associated with these and other regulatory
matters have been borne by NYLIM. Except as described below, neither NYLIM nor
the funds advised by it have any reason to believe that they have been targeted
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 Fund and the fees and expenses of that Fund, as well as the
related guarantee disclosure to Fund shareholders. Discussions have been held
with the SEC concerning a possible resolution of this matter. These discussions
are continuing, but there can be no assurance at this time as to the outcome of
these efforts.

NOTE 12 -- SUBSEQUENT EVENT:

Subsequent to October 31, 2004, the Fund declared a dividend of $0.4138 per
share which was paid on December 21, 2004, and also underwent a reverse share
split on that day. The reverse share split rate was 0.9897 per share outstanding
calculated on fund shares outstanding immediately after reinvestment of
dividends.

Certain amounts in the Statement of Assets and Liabilities, Financial
Highlights, and Notes to Financial Statements (see Note 8) have been adjusted to
reflect the effects of this subsequent reverse stock split.

NOTE 13 -- CHANGE IN INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM (UNAUDITED):

On March 8, 2004, KPMG LLP ("KPMG") was selected as the Trust's independent
auditor for the 2004 fiscal year. The selection of KPMG was recommended by the
Trust's Audit Committee, comprised of all Non-Interested Trustees, and was
approved by the Trust's Board of Trustees.

 24   MainStay Equity Index Fund


The predecessor independent auditor's reports on the Trust's financial
statements for the period ended October 31, 2003 and year ended December 31,
2002 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 periods, and through the date of engagement of KPMG, there
were no disagreements between 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 periods.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Trustees and Shareholders of
The MainStay Funds:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of the MainStay Equity Index Fund (the "Fund"),
one of the funds constituting The MainStay Funds, as of October 31, 2004, and
the related statement of operations, statement of changes in net assets and the
financial highlights for the year then ended. These financial statements and
financial highlights are the responsibility of the Fund's management. Our
responsibility is to express an opinion on these financial statements and
financial highlights based on our audit. The statement of changes in net assets
for the period ended October 31, 2003 and the year ended December 31, 2002, and
the financial highlights for the periods presented through October 31, 2003,
were audited by other auditors, whose report dated December 18, 2003 expressed
an unqualified opinion thereon.

We conducted our audit in accordance with the Standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
also includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2004 by correspondence with the custodian and
brokers. As to securities purchased or sold but not yet received or delivered,
we performed other appropriate auditing procedures. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
MainStay Equity Index Fund of The MainStay Funds as of October 31, 2004, the
results of its operations, the changes in its net assets and its financial
highlights for the year then ended, in conformity with U.S. generally accepted
accounting principles.

MESSAGE FROM
THE PRESIDENT

During the 12 months ended October 31, 2004, the U.S. stock market advanced, but
its pace and direction were by no means steady. Small- and mid-capitalization
stocks tended to outperform large-cap issues, and value stocks generally
outperformed growth stocks.

Economic activity, as measured by gross domestic product, increased from 4.2% in
the fourth quarter of 2003 to 4.5% in the first quarter of 2004. The pace of
economic growth slowed to 3.3% in the second quar-
ter of 2004, and according to preliminary estimates from the Bureau of Economic
Analysis, gross domestic product grew at a seasonally adjusted annual rate of
3.9% in the third quarter of 2004.

Interest rates began the reporting period at a low 1.00%. In June 2004, the
Federal Open Market Committee responded to expanding output and improved labor
markets by raising the targeted federal funds rate by 25 basis points. Similar
moves in August and September brought the targeted federal funds rate to 1.75%.
In its September 2004 release, the Federal Open Market Committee affirmed its
belief that monetary policy remained accommodative.

Despite rising interest rates, bond markets generally advanced. High-yield bonds
and emerging-market debt were particularly strong. The U.S. dollar declined
relative to most other currencies, which helped U.S. exporters.

In pursuing its investment objective, each MainStay Fund consistently seeks to
apply a well-defined investment process in all market environments. We believe
that a consistent, disciplined investment approach can help investors make more
prudent and practical decisions regarding their investments.

In the report that follows, you'll find additional information about the market
forces, investment decisions, and individual securities that affected your
MainStay Fund during the 12 months ended October 31, 2004. We thank you for
investing with us, and we look forward to many years of continued service in
your behalf.

Sincerely,
/s/ GARY E. WENDLANDT
Gary E. Wendlandt
President

Performance tables and graphs do not reflect the deduction of taxes that a
shareholder would pay on distributions or Fund-share redemptions. Total returns
reflect change in share price, reinvestment of dividend and capital-gain
distributions, and maximum applicable sales charges explained in this paragraph.
The graphs assume an initial investment of $10,000 and reflect the deduction of
all sales charges that would have applied for the period of investment. Class A
shares are sold with a maximum initial sales charge of 4.5% and an annual 12b-1
fee of .25%. Class B shares are sold with no initial sales charge, are subject
to a contingent deferred sales charge (CDSC) of up to 5% if redeemed within the
first six years of purchase, and have an annual 12b-1 fee of 1.00%. Class C
shares are sold with no initial sales charge, are subject to a CDSC of 1% if
redeemed within one year of purchase, and have an annual 12b-1 fee of 1.00%.
Class I shares are sold with no initial sales charge or CDSC, have no annual
12b-1 fee, and are generally available to corporate and institutional investors
with a minimum initial investment of $5 million. From inception (5/1/86) through
12/31/94 (for Class A, first offered 1/3/95), 8/31/98 (for Class C, first
offered 9/1/98), and 12/31/03 (for Class I, first offered 1/2/04), performance
of Class A, C, and I includes the historical performance of Class B shares
adjusted to reflect the applicable sales charge (or CDSC) and fees and expenses

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

Questions answered by portfolio managers Gary Goodenough and Joseph Portera of
MacKay Shields LLC

WHAT ECONOMIC FACTORS INFLUENCED THE BOND MARKET DURING THE 12 MONTHS ENDED
OCTOBER 31, 2004?

The Federal Reserve maintained the targeted federal funds rate at an
accommodative 1.00% through the first half of the Fund's fiscal year, but for
much of that period, economic data was mixed. With slack in the labor markets,
slack in manufacturing capacity, and little pricing power in most industries, it
appeared that there was little risk of the economy overheating. In April 2004,
however, uniformly firm economic releases challenged that view. The risk of
deflation appeared to be waning, while trend-level growth appeared sustainable.
The consensus was that the Federal Reserve's cautionary stance would be
relatively short-lived. Consistent with market expectations, the Federal Open
Market Committee tightened monetary policy at its June 30, 2004, meeting by
raising the targeted federal funds rate to 1.25%. Another 25-basis-point rate
hike followed in August, and yet another in September. These moves brought the
targeted federal funds rate to 1.75% at the end of October 2004.

HOW DID THESE FACTORS AFFECT TREASURY YIELDS?

During the 12-month reporting period, the U.S. Treasury yield curve pivoted
around the five-year maturity benchmark. Two-year Treasury yields rose from 1.8%
to 2.6%; five-year yields were basically unchanged at 3.25%; 10-year yields fell
from 4.3% to 4.0%; and 30-year yields declined from 5.1% to 4.8%. The narrowing
of the yield spread between the two-year and 30-year maturities (commonly known
as a flattening of the yield curve) was not solely a result of Federal Open
Market Committee interest-rate tightening. The flattening also stemmed from
lower inflation expectations and large block purchases of U.S. Treasury
securities by foreign governments.

CAN YOU BRIEFLY DESCRIBE THE FUND'S INVESTMENT APPROACH?

The Fund normally invests at least 80% of its assets in U.S. government
securities. It may invest up to 20% of its assets in mortgage-related and
asset-backed securities or other securities that are not U.S. government
securities. In implementing this strategy, we use a combined approach to
investing. We analyze economic trends as well as factors pertinent to particular
issuers and securities. The Fund's principal investments include U.S. Treasury
bills, notes, and bonds, Ginnie Mae certificates, and other U.S. government
securities representing ownership interests in mortgage pools, such as
securities issued by Fannie Mae and Freddie Mac. We may sell securities when the
condition of the economy, meaningful changes in an issuer's condition, or other
factors suggest that the securities will no longer contribute to the Fund's
ability to meet its investment objective.

HOW DID YOU POSITION THE FUND'S PORTFOLIO ACROSS THE VARIOUS BOND SECTORS
AVAILABLE TO THE FUND?

The Fund's performance was positively affected by our preference for securities
other than U.S. Treasuries during the reporting period. We favored what are
known as securitized products for their high quality, liquidity, and yield
advantage to Treasuries. We diversified the Fund's commitment to these products
across agency debentures, residential mortgage-backed securities, commercial
mortgage-backed securities, and asset-backed securities. Of these, agency
debentures, residential mortgage-backed securities, and asset-backed securities
each outperformed U.S. Treasuries for the 12-month reporting period. These
sectors tend to do well when U.S. Treasury yields are range-bound, since cash
flows are more predictable under these conditions. As described above, Treasury
yields for maturities of five years and longer held to a fairly tight range
during the annual period.

At the end of the period, the Fund's net assets were invested 18% in U.S.
Treasuries, 17% in agency debentures, 55% in mortgage-backed securities issued
by government-sponsored and government-related enterprises, 6% in asset-backed
securities, and 4% in investment-grade credits. In total, the allocation to
non-government-related securities did not exceed 10%.

DID YOU MAKE ANY CHANGES TO THE FUND'S ALLOCATION DURING THE REPORTING PERIOD?

We reduced the Fund's allocation to Treasuries and evenly split the proceeds
between agency debentures and mortgage-backed securities. These trades boosted
the yield of the Fund without compromising credit quality, and they shortened
the Fund's duration.

Investments in the Fund are not guaranteed, even though some of the Fund's
investments are guaranteed by the U.S. government or its agencies or
instrumentalities. 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.

HOW DID THE FUND'S YIELD CURVE AND DURATION POSITIONING AFFECT PERFORMANCE?

We maintained a neutral yield-curve posture during the 12-month reporting
period, so the flattening of the yield curve had minimal impact on the Fund's
performance. The Fund's duration, however, detracted from the Fund's relative
results. The duration effect outweighed the benefits of our focus on securities
that tend to trade at higher-than-Treasury yields.

CAN YOU BE MORE SPECIFIC ABOUT THE FUND'S DURATION POSITIONING?

In April, the Fund's duration posture, which was longer than the average
duration of other intermediate government bond funds, hurt relative performance
when interest rates climbed. We decided to shift the Fund's duration closer to
the median duration(1) by selling long-term Treasuries and buying shorter-
duration mortgage-backed securities and agency debentures. Yield trends for the
balance of the fiscal year, however, did not work in favor of this
repositioning. What we failed to appreciate was the sizeable impact of a weaker
U.S. dollar on interest rates. Specifically, foreign central banks bought large
blocks of U.S. Treasuries to stall the appreciation of their currencies against
the weaker U.S. dollar. Foreign central banks undertook this action to keep the
price of U.S. exports from falling relative to the prices of domestic goods. The
foreign central banks sought to ease deflationary pressures that might impede
the recovery of their home economies. In addition, Treasury yields for
maturities of five years and longer declined significantly between the end of
April and the end of October, which worked against our duration adjustment. At
the end of October 2004, the Fund's duration stood at 3.7 years, toward the
lower end of our target duration range.

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

At the end of the fiscal year, the eurodollar futures market predicted a 2.5%
targeted U.S. federal funds rate by March 2005. We agree with this view. As we
move toward 2005, we feel that a pick-up in economic growth is a reasonable
assumption given low interest rates, lower marginal tax rates, low inflation,
firm consumer-spending patterns, and improved corporate confidence. We believe
that the balance of the Federal Reserve's move in interest rates can be
accomplished at a reasonable, measured pace. As long as consumers remain highly
leveraged and productivity growth continues to drive labor costs lower, the
Federal Reserve has little incentive to be more aggressive, unless inflation
begins to accelerate.

HOW ARE YOU POSITIONING THE FUND GIVEN YOUR VIEW?

We intend to maintain the Fund's shorter-than-benchmark duration for the near
term. This positioning supports our view of the economy and interest rates, as
well as the need for increased Treasury issuance to fund the federal budget
imbalance. We also intend to continue favoring sectors other than U.S.
Treasuries. In terms of Treasury inflation-protected securities (TIPS), we are
less confident. We believe TIPS offer limited value relative to
duration-equivalent nominal Treasuries at current inflation levels. If the
Treasury yield curve were to steepen, which usually signals that the market
expects inflation to rise, then we might reassess our view.

1. The Fund's duration is gauged against the duration of the median fund in the
   Lipper government securities fund universe. Analysis of performance data
   suggests that the duration of the average fund is longer than that of the
   median fund. Lipper Inc. is an independent fund performance monitor.

NOTES TO FINANCIAL STATEMENTS

NOTE 1 -- ORGANIZATION AND BUSINESS:

The MainStay Funds (the "Trust") was organized on January 9, 1986 as a
Massachusetts business trust. The Trust is registered under the Investment
Company Act of 1940, as amended (the "1940 Act"), as an open-end management
investment company and comprises twenty-two funds (collectively referred to as
the "Funds"). These financial statements and notes relate only to MainStay
Government Fund (the "Fund"), a diversified fund.

The Fund currently offers four classes of shares. Class A shares, whose
distribution commenced on January 3, 1995, 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 within one year of purchase of Class C
shares. Distribution of Class B shares and Class C shares commenced on May 1,
1986 and September 1, 1998, respectively. Class I shares are not subject to
sales charge. Distribution of Class I shares commenced on January 2, 2004. Class
A shares, Class B shares, Class C shares and Class I shares bear the same voting
(except for issues that relate solely to one class), dividend, liquidation and
other rights and conditions. Each class of shares other than Class I shares
bears distribution and/or service fee payments under a distribution plan
pursuant to Rule 12b-1 under the 1940 Act. Class I shares are not subject to a
distribution or service fee.

The Fund's investment objective is to seek a high level of current income,
consistent with safety of principal.

NOTE 2 -- SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with generally accepted
accounting principles and follows the significant accounting policies described
below.

(A) SECURITIES VALUATION.  Debt securities are valued at prices supplied by a
pricing agent selected by the Fund's Manager, whose prices reflect broker/dealer
supplied valuations and electronic data processing techniques, if those prices
are deemed by the Fund's Manager to be representative of market values, at the
regular close of business of the New York Stock Exchange. 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. Securities for which market
quotations are not readily available are valued by methods deemed by the Board
of Trustees to represent fair value. Reasons for which securities may be valued
in this manner include, but are not limited to, trading for a security has been
halted or suspended, a security has been de-listed from a national exchange, or
trading on a security's primary market is temporarily closed at a time when
under normal conditions it would be open. The Fund did not hold securities at
October 31, 2004, that were valued in such manner.

(B) MORTGAGE DOLLAR ROLLS.  The Fund enters into mortgage dollar roll ("MDR")
transactions in which it sells mortgage-backed securities ("MBS") from its
portfolio to a counterparty from whom it simultaneously agrees to buy a similar
security on a delayed delivery basis. The MDR transactions of the Fund are
classified as purchase and sale transactions. The securities sold in connection
with the MDRs are removed from the portfolio and a realized gain or loss is
recognized. The securities the Fund has agreed to acquire are included at market
value in the portfolio of investments and liabilities for such purchase
commitments are included as payables for investments purchased. 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.

(C) SECURITIES LENDING.  The Fund may lend its securities to broker-dealers and
financial institutions. The loans are collateralized by cash or securities at
least equal at all times to the market value of the securities loaned. The Fund
may bear the risk of delay in recovery of, or loss of rights in, the securities
loaned should the borrower of the securities experience financial difficulty.
The Fund receives compensation for lending its securities in the form of fees or
it retains a portion of interest on the investment of any cash received as
collateral. The Fund also continues to receive interest and dividends on the
securities loaned and any gain or loss in the market price of the securities
loaned that may occur during the term of the loan will be for the account of the
Fund. (See Note 7.)

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

(E) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are
recorded on the ex-dividend date. The Fund intends to declare and pay dividends
monthly and capital gain distributions, if any, annually. Income dividends and
capital gain distributions are determined in accordance with federal income tax

 18   MainStay Government Fund


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.

The following table discloses the current year reclassifications between
distributions in excess of net investment income, accumulated net realized loss
and additional paid-in capital arising from permanent differences; net assets at
October 31, 2004 are not affected.

<Table>

       $3,776,494             $8,462,615       $(12,239,109)
 ----------------------------------------------------------------
</Table>

The reclassifications for the Fund are primarily due to a tax return of capital
and expiration of capital loss carryforwards for tax purposes.

(F) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  The Fund records security
transactions on the trade date. Realized gains and losses on security
transactions are determined using the identified cost method and include gains
and losses from repayments of principal on mortgage backed securities. Interest
income is accrued as earned. Discounts and premiums on securities, other than
short-term securities, purchased for the Fund are accreted and amortized,
respectively, on the constant yield method over the life of the respective
securities or, in the case of 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 expenses and realized and unrealized gains and losses on
investments of the 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.

(G) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred except where direct allocations of expenses can be made. Expenses
(other than expenses incurred under the distribution plans) are allocated to
separate classes of shares based upon their relative net asset value on the date
the expenses are incurred. The expenses borne by the Fund, including those of
related parties to the Fund, are shown in the Statement of Operations.

(H) 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.

NOTE 3 -- FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER AND SUBADVISOR.  New York Life Investment Management LLC ("NYLIM" or
the "Manager"), an indirect wholly-owned subsidiary of New York Life Insurance
Company ("New York Life"), serves as the Fund's manager. The Manager provides
offices, conducts clerical, recordkeeping and bookkeeping services, and keeps
the financial and accounting records required for the Fund. The Manager also
pays the salaries and expenses of all personnel affiliated with the Fund and all
the operational expenses that are not the responsibility of the Fund. MacKay
Shields LLC (the "Subadvisor"), a registered investment adviser and indirect
wholly-owned subsidiary of New York Life, is responsible for the day-to-day
portfolio management of the Fund.

Through July 31, 2004 the Trust, on behalf of the Fund, paid the Manager a
monthly fee for services performed and the facilities furnished at an annual
rate of 0.60% of the Fund's average daily net assets on assets up to $1 billion
and 0.55% annually on assets in excess of $1 billion. Effective as of August 1,
2004, NYLIM has voluntarily agreed to waive its management fee by 0.10% of the
Fund's average net assets. In addition, effective December 1, 2004, NYLIM has
voluntarily agreed to reimburse the expenses of the Fund to the extent that
operating expenses would exceed on an annualized basis 1.05%, 1.80% and 1.80% of
the average daily net assets of the Class A, Class B and Class C shares,
respectively, and an equivalent reduction in the management fee for Class I. For
the year ended October 31, 2004, the Manager earned from the Fund $2,805,337,
and waived $108,955 of its fee.

Pursuant to the terms of a Sub-Advisory Agreement between NYLIM and MacKay
Shields, the Manager pays the Subadvisor a monthly fee of 0.30% of the Fund's
average daily net assets on assets up to $1 billion and 0.275% on assets in
excess of $1 billion. To the extent the Manager has agreed to reimburse expenses
of the Fund, the Subadvisor has voluntarily agreed to do so proportionately.

(B) DISTRIBUTION AND SERVICE FEES.  The Trust, on behalf of the Fund, has a
Distribution Agreement with NYLIFE Distributors LLC (the "Distributor"), an
indirect wholly-owned subsidiary of New York Life. The Fund, with respect to
each class of shares other than Class I shares, has adopted distribution plans
(the "Plans") in accordance with the provisions of Rule 12b-1 under the 1940
Act. Pursuant to the Class A Plan, the Distributor receives a monthly fee from
the Fund at an annual rate of 0.25% of the average daily net assets of the
Fund's Class A shares, which is an expense of the Class A shares of the Fund for

                                                    www.mainstayfunds.com     19

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

distribution or service activities as designated by the Distributor. Pursuant to
the Class B and Class C Plans, the Fund pays the Distributor a monthly fee,
which is an expense of the Class B and Class C shares of the Fund, at the annual
rate of 0.75% of the average daily net assets of the Fund's Class B and Class C
shares. The Distribution Plans provide that the Class B and Class C shares of
the Fund 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 Fund. Class I
shares are not subject to a distribution or service fee.

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

(C) SALES CHARGES.  The Fund was advised by the Distributor that the amount of
sales charges retained on sales of Class A shares was $20,960 for the year ended
October 31, 2004. The Fund was also advised that the Distributor retained
contingent deferred sales charges for redemption of Class A, Class B and Class C
shares of $9,536, $241,096 and $5,664, respectively, for the year ended October
31, 2004.

(D) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT.  NYLIM
Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's
transfer, dividend disbursing and shareholder servicing agent. NYLIM Service has
entered into an agreement with Boston Financial Data Services ("BFDS") pursuant
to which BFDS will perform certain of the services for which NYLIM Service is
responsible. Transfer agent expenses for the year ended October 31, 2004,
amounted to $1,527,195.

(E) NON-INTERESTED TRUSTEES FEES.  Non-Interested Trustees are paid an annual
retainer fee of $45,000, $2,000 for each Board meeting, $1,000 for each
Committee meeting and $500 for each Valuation Subcommittee telephonic meeting
attended plus reimbursement for travel and out-of-pocket expenses. The Lead
Non-Interested Trustee is also paid an annual retainer fee of $20,000. The Audit
Committee Chairman receives an additional $2,000 for each meeting of the Audit
Committee attended and the Chairpersons of the Brokerage Committee, Operations
Committee and Performance Committee each receive an additional $1,000 for each
meeting of the Brokerage Committee, Operations Committee and Performance
Committee attended, respectively. In addition, each Non-Interested Trustee is
paid $1,000 for attending meetings of the Non-Interested Trustees held in
advance of or in connection with Board/Committee meetings. The Trust allocates
trustees fees in proportion to the net assets of the respective Funds. Thus the
Government Fund only pays a portion of the fees identified above.

(F) OTHER.  Fees for the cost of legal services, included in professional
expenses as shown on the Statement of Operations, provided to the Fund by the
Office of the General Counsel of NYLIM, amounted to $13,575 for the year ended
October 31, 2004.

The Fund pays the Manager a monthly fee for recordkeeping services provided
under the Accounting Agreement at the annual rate of 1/20 of 1% for the first
$20 million of average monthly net assets, 1/30 of 1% of the next $80 million of
average monthly net assets and 1/100 of 1% of any amount in excess of $100
million of average monthly net assets. Fees for recordkeeping services provided
to the Fund by the Manager amounted to $73,420 for the year ended October 31,
2004.

NOTE 4 -- CUSTODIAN:

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

NOTE 5 -- FEDERAL INCOME TAX:

As of October 31, 2004, the components of accumulated loss on a tax basis were
as follows:

<Table>

 ------------------------------------------------------
</Table>

The difference between book-basis and tax-basis unrealized appreciation is
primarily due to premium amortization adjustments.

At October 31, 2004 for federal income tax purposes, capital loss carryforwards
of $42,344,625 were available as shown in the table below, to the extent
provided by the regulations, to offset future realized gains of the Fund through
the years indicated. To the extent that these carryforwards are used to offset
future capital gains, it is probable that the capital gains so offset will not
be distributed to shareholders.

amount, regardless of usage, to The Bank of New York, which acts as agent to the
syndicate. Such commitment fees are allocated among the funds based upon net
assets and other factors. Interest on any revolving credit loan is charged based
upon the Federal Funds Advances rate. There were no borrowings on the line of
credit during the year ended October 31, 2004.

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

NOTE 10 -- OTHER MATTERS:

NYLIM and mutual funds that NYLIM advises have received requests for information
from various government authorities and regulatory bodies regarding market
timing, late trading, operations, fees, expenses, and other matters. NYLIM and
the funds it advises are cooperating fully in responding to these requests. As
reported in response to those requests for information, NYLIM was previously
party to agreements with certain registered representatives of broker-dealers
relating to the level of trading by clients or customers of those registered
representatives in shares of certain funds of the Trust. NYLIM is continuing to
review what effect, if any, transactions under these agreements may have had on
the funds, and will continue to apprise the Board of Trustees of such
information. NYLIM does not believe at this time that such trading had any
material effect on the funds' financial statements or their shareholders. To
date, substantially all of the costs associated with these and other regulatory
matters have been borne by NYLIM. Except as described below, neither NYLIM nor
the funds advised by it have any reason to believe that they have been targeted
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.
Discussions have been held with the SEC concerning a possible resolution of this
matter. These discussions are continuing, but there can be no assurance at this
time as to the outcome of these efforts.

NOTE 11 -- CHANGE IN INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM (UNAUDITED):

On March 8, 2004, KPMG LLP ("KPMG") was selected as the Trust's independent
auditor for the 2004 fiscal year. The selection of KPMG was recommended by the
Trust's Audit Committee, comprised of all Non-Interested Trustees, and was
approved by the Trust's Board of Trustees.

The predecessor independent auditor's reports on the Trust's financial
statements for the period ended October 31, 2003 and year ended December 31,
2002 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 periods, and through the date of engagement of KPMG, there
were no disagreements between 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 periods.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Trustees and Shareholders of
The MainStay Funds:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of the MainStay Government Fund (the "Fund"), one
of the funds constituting The MainStay Funds, as of October 31, 2004, and the
related statement of operations, statement of changes in net assets and the
financial highlights for the year or period then ended. These financial
statements and financial highlights are the responsibility of the Fund's
management. Our responsibility is to express an opinion on these financial
statements and financial highlights based on our audit. The statement of changes
in net assets for the period ended October 31, 2003 and the year ended December
31, 2002, and the financial highlights for the periods presented through October
31, 2003, were audited by other auditors, whose report dated December 18, 2003
expressed an unqualified opinion thereon.

We conducted our audit in accordance with the Standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
also includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2004 by correspondence with the custodian and
brokers. As to securities purchased or sold but not yet received or delivered,
we performed other appropriate auditing procedures. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
MainStay Government Fund of The MainStay Funds as of October 31, 2004, the
results of its operations, the changes in its net assets and its financial
highlights for the year or period then ended, in conformity with U.S. generally
accepted accounting principles.

                    Annual Report
                    October 31, 2004


MESSAGE FROM
THE PRESIDENT

During the 12 months ended October 31, 2004, the U.S. stock market advanced, but
its pace and direction were by no means steady. Small- and mid-capitalization
stocks tended to outperform large-cap issues, and value stocks generally
outperformed growth stocks.

Economic activity, as measured by gross domestic product, increased from 4.2% in
the fourth quarter of 2003 to 4.5% in the first quarter of 2004. The pace of
economic growth slowed to 3.3% in the second quarter of 2004, and according to
preliminary estimates from the Bureau of Economic Analysis, gross domestic
product grew at a seasonally adjusted annual rate of 3.9% in the third quarter
of 2004.

Interest rates began the reporting period at a low 1.00%. In June 2004, the
Federal Open Market Committee responded to expanding output and improved labor
markets by raising the targeted federal funds rate by 25 basis points. Similar
moves in August and September brought the targeted federal funds rate to 1.75%.
In its September 2004 release, the Federal Open Market Committee affirmed its
belief that monetary policy remained accommodative.

Despite rising interest rates, bond markets generally advanced. High-yield bonds
and emerging-market debt were particularly strong. The U.S. dollar declined
relative to most other currencies, which helped U.S. exporters.

In pursuing its investment objective, each MainStay Fund consistently seeks to
apply a well-defined investment process in all market environments. We believe
that a consistent, disciplined investment approach can help investors make more
prudent and practical decisions regarding their investments.

In the report that follows, you'll find additional information about the market
forces, investment decisions, and individual securities that affected your
MainStay Fund during the 12 months ended October 31, 2004. We thank you for
investing with us, and we look forward to many years of continued service in
your behalf.

Sincerely,
/s/ GARY E. WENDLANDT
Gary E. Wendlandt
President

Performance tables and graphs do not reflect the deduction of taxes that a
shareholder would pay on distributions or Fund-share redemptions. Total returns
reflect change in share price, reinvestment of dividend and capital-gain
distributions, and maximum applicable sales charges explained in this paragraph.
The graphs assume an initial investment of $10,000 and reflect the deduction of
all sales charges that would have applied for the period of investment. Class A
shares are sold with a maximum initial sales charge of 4.5% and an annual 12b-1
fee of .25%. Class B shares are sold with no initial sales charge, are subject
to a contingent deferred sales charge (CDSC) of up to 5% if redeemed within the
first six years of purchase, and have an annual 12b-1 fee of 1.00%. Class C
shares are sold with no initial sales charge, are subject to a CDSC of 1% if
redeemed within one year of purchase, and have an annual 12b-1 fee of 1.00%.
Class I shares are sold with no initial sales charge or CDSC, have no annual
12b-1 fee, and are generally available to corporate and institutional investors
with a minimum initial investment of $5 million. From inception (5/1/86) through
12/31/94 (for Class A, first offered 1/3/95), 8/31/98 (for Class C, first
offered 9/1/98), and 12/31/03 (for Class I, first offered 1/2/04), performance
of Class A, C, and I shares includes the historical performance of Class B
shares adjusted to reflect the applicable sales charge (or CDSC) and fees and
expenses for Class A, C, and I 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 data 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 Donald E. Morgan and J. Matthew Philo
of MacKay Shields LLC

CAN YOU BRIEFLY DESCRIBE THE FUND'S INVESTMENT APPROACH?

The Fund normally invests at least 80% of its assets in high-yield corporate
debt securities, including all types of high-yield domestic and foreign
corporate debt securities that are rated below investment grade by Moody's or
S&P or, if unrated, that we consider to be of comparable quality. In
implementing this strategy, we seek to identify investment opportunities based
primarily on the financial condition and competitiveness of individual
companies. The Fund's principal investments include domestic corporate debt
securities, Yankee or dollar-denominated debt securities, zero coupon bonds,
U.S. government securities, convertible corporate bonds, and loan participation

WHAT TRENDS DROVE THE STRONG PERFORMANCE OF THE HIGH-YIELD MARKET DURING THE 12
MONTHS ENDED OCTOBER 31, 2004?

The high-yield-bond bull market that started in the fourth quarter of 2002
continued through most of the 12-month reporting period. Advances were fueled by
positive fundamental and technical factors. High-yield default rates continued
to decline from their peak in 2002, which encouraged investors. An ongoing
economic recovery increased the probability that high-yield issuers would meet
their debt obligations. New money also flowed into the asset class during the
reporting period, and the supply of new issuance failed to keep up with demand.
In addition, high-yield bonds were being refinanced at more-attractive interest
rates, which resulted in frequent tenders. (A tender is a payment for bonds
called prior to maturity.) This refinancing activity significantly decreased the
difference in yield between high-yield bonds and comparable investment-grade
bonds. Such a decrease is often referred to as spread tightening. The three
25-basis-point Federal Reserve interest-rate hikes--one in June, one in August,
and one in September of 2004--were widely anticipated by investors and were
already priced into the market by the time the Federal Open Market Committee
actually raised the targeted federal funds rate.

WHAT EFFECT DID THESE MARKET TRENDS HAVE ON THE FUND?

As a result of the high-yield bond market's upward climb, we kept cash levels in
the Fund higher than usual during the reporting period. We found only a limited
number of attractive buying opportunities, and we had some concerns regarding
the quality of newly issued securities. The Fund also experienced higher-
than-normal tenders from bond issuers, which further added to the Fund's cash
level.

HOW DID YOU POSITION THE FUND FROM A SECTOR OR INDUSTRY PERSPECTIVE?

We are bottom-up investors, so the Fund's exposure to various sectors and
industries is primarily the result of individual security selection. Over the 12
months ended October 31, 2004, we reduced the Fund's exposure to utilities,
wireless communications, telecommunications, information technology, and
food/tobacco bonds. We increased the Fund's absolute weightings in bonds issued
by services and chemicals companies. At the end of October 2004, the Fund's
largest overweighted positions relative to the Credit Suisse First Boston(TM)
High Yield Index(2) were in broadcasting, cable/wireless, and airlines. At the
same time, the Fund held underweighted positions relative to the benchmark index
in gaming, manufacturing, and food & drug bonds.

DID YOU ADJUST THE FUND'S DURATION POSITIONING DURING THE PERIOD?

As bottom-up investors, duration is primarily a residual of our investment
process. We believe that high-yield bonds have risk and reward characteristics
similar to those of equities. For this reason, traditional fixed-income
strategies, such as yield-curve positioning, maturity structure, and duration
management, are not the focal point of our investment process. That said, we
believe that our general duration parameters of plus or minus 10% of the
benchmark index may tend to reduce

High-yield debt securities ("junk bonds") are generally considered speculative
because they present a greater risk of loss than higher- quality debt securities
and may be subject to greater price volatility. 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. Bonds rated B by Moody's Investors Service are deemed by Moody's to generally
   lack characteristics of the desirable investment. According to Moody's,
   assurance of interest and principal payments or of maintenance of other terms
   of the contract over any long period of time may be small. Debt rated B by
   Standard & Poor's is deemed by Standard & Poor's to be more vulnerable to
   nonpayment than obligations rated BB, but it is the opinion of Standard &
   Poor's that the obligor currently has the capacity to meet its financial
   commitment on the obligation. Standard & Poor's believes that adverse
   business, financial, or economic conditions will likely impair the obligor's
   capacity or willingness to meet its financial commitment on the obligation.
   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 duration risk of the Fund. We feel that the ultimate driver of high-yield
returns is the default rate, which has steadily decreased over the last 24
months. While rising interest rates might have a negative impact on the Fund, we
would expect the effects to be less than the related impact on investment-grade
debt. Over the last 12 months, the yield on the 10-year Treasury bond fell from
4.30% to 4.03%. Over the same period, high-yield bonds rallied even more, with
the yield on the Credit Suisse First Boston(TM) High Yield Index falling from
8.36% to 7.26%. (The term "rally" is used because bond prices tend to rise when
yields fall.)

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

The Fund's metal-related bonds--such as AK Steel, Algoma Steel, and Allegheny
Ludlum--were among the top performers for the 12-month reporting period, as the
prices of many basic commodities, including steel, exhibited meaningful
strength. An increase in North American manufacturing activity contributed to
this trend. A weaker U.S. dollar and strong end-user demand in Asia also reduced
the threat posed by low-priced imported steel. These trends also made the
removal of protective tariffs by the Bush administration in November 2003
something of a nonevent for the industry.

Cable companies, including FrontierVision and UGC Europe, were also among the
Fund's strongest performers during the reporting period. In December 2003,
UnitedGlobalCom acquired all shares of the recently reorganized UGC Europe.
These companies were among several cable providers that reported good earnings
over the 12-month period, leading to upbeat expectations for the industry as a
whole.

WERE THERE OTHER AREAS OF STRENGTH IN THE FUND'S PORTFOLIO?

Several of the Fund's wireless companies performed well during the reporting
period. US Unwired, Alamosa, Nextel International, and Mobifon each outperformed
related securities in the CSFB High Yield Index. The Fund's holdings in Nextel
International consisted of equity received as the result of a restructuring at
the beginning of 2003.

WERE THERE ANY HOLDINGS THAT DIDN'T MEET YOUR EXPECTATIONS?

The Fund's investments in the airline industry had disappointing performance, as
airline costs climbed with the rising price of oil. Concerns about a possible
bankruptcy at Delta Airlines affected our position in the company. Delta sought
a resolution with the pilots' union that didn't arrive until the end of October
2004. Delta Airlines and Northwest Airlines were among the Fund's poorest
performers during the reporting period.

Other Fund holdings that produced disappointing results were securities issued
by utilities company Calpine and machinery company Thermadyne Holdings.

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

Over the 12 months ended October 31, 2004, we initiated positions in several
securities. The Fund lost UGC Europe bonds and took on UnitedGlobalCom stock as
part of a corporate action. Other significant additions to the Fund's portfolio
included issues of El Paso Production Holdings, Ono Finance, Goodyear Tire &
Rubber, and Rainbow National Services. We eliminated Fund holdings in Pacific
G&E and Alamosa PCS Holding. We also sold securities of Nextel International
that the Fund had received during the company's restructuring.

WHAT DO YOU ANTICIPATE FOR THE HIGH-YIELD BOND MARKET GOING FORWARD?

We believe the high-yield bond market may have now approached fair value
relative to U.S. Treasuries. Thus, we are becoming concerned that we may not be
adequately compensated for both interest-rate risk and credit risk at current
yield-spread levels. We intend to increase the Fund's exposure to floating-rate
debt and to actively sell bonds that have reached our price targets. We may also
allow the Fund's cash levels to remain higher than normal until we see a
correction in the high-yield bond market. In our view, the opportunity cost of
elevated cash levels versus high-yield bonds is not as great as deviating from
our investment process simply to lower the cash level of the portfolio. We will
seek to use the cash tactically, taking quick action should investment
opportunities arise, especially in the new-issue market.

NOTES TO FINANCIAL STATEMENTS

NOTE 1 -- ORGANIZATION AND BUSINESS:

The MainStay Funds (the "Trust") was organized on January 9, 1986 as a
Massachusetts business trust. The Trust is registered under the Investment
Company Act of 1940, as amended (the "1940 Act"), as an open-end management
investment company and comprises twenty-two funds (collectively referred to as
the "Funds"). These financial statements and notes relate only to MainStay High
Yield Corporate Bond Fund (the "Fund"), a diversified fund.

The Fund currently offers four classes of shares. Class A shares, whose
distribution commenced on January 3, 1995, 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 within one year of purchase of Class C
shares. Distribution of Class B shares and Class C shares commenced on May 1,
1986 and September 1, 1998, respectively. Class I shares are not subject to
sales charge. Distribution of Class I shares commenced on January 2, 2004. Class
A shares, Class B shares, Class C shares and Class I shares bear the same voting
(except for issues that relate solely to one class), dividend, liquidation and
other rights and conditions. Each class of shares other than Class I shares
bears distribution and/or service fee payments under a distribution plan
pursuant to Rule 12b-1 under the 1940 Act. Class I shares are not subject to a
distribution or service fee.

The Fund's investment objective is to seek maximum income through investment in
a diversified portfolio of high yield debt securities. Capital appreciation is a
secondary objective.

The Fund principally invests in high yield securities (sometimes called "junk
bonds"), which are generally considered speculative because they present a
greater risk of loss, including default, than higher quality debt securities.
These securities pay a premium -- a high interest rate or yield -- because of
the increased risk of loss. These securities can also be subject to greater
price volatility.

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

NOTE 2 -- SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with generally accepted
accounting principles and follows the significant accounting policies described
below.

(A) SECURITIES VALUATION.  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 New York Stock Exchange
(generally 4:00 p.m.). Equity securities are valued at the latest quoted sales
prices as of the close of trading on the Exchange 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. Foreign currency forward contracts are valued at their
fair market value determined on the basis of the mean between the last current
bid and asked prices based on dealer or exchange quotations. 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. Securities for which market
quotations are not readily available are valued by methods deemed by the Board
of Trustees to represent fair value. Reasons for which securities may be valued
in this manner include, but are not limited to, trading for a security has been
halted or suspended, a security has been de-listed from a national exchange, or
trading on a security's primary market is temporarily closed at a time when
under normal conditions it would be open. At October 31, 2004, the Fund held
securities with a value of $17,560,693 that were valued in such manner.

Certain events may occur between the time that foreign markets close, on which
securities held by the Fund principally trade, and the time at which the Fund's
NAV is calculated. These events may include, but are not limited to, situations
relating to a single issue in a market sector, significant fluctuations in U.S.
or foreign markets, natural disasters, armed conflicts, governmental actions or
other developments not tied directly to the securities markets. Should the
Manager or Subadvisor conclude that such events may have affected the accuracy
of the last price reported on the local foreign market, the Manager or
Subadvisor may, pursuant to procedures adopted by the Fund, adjust the value of
the local price to reflect the impact on the price of such securities as a
result of such events.

 26   MainStay High Yield Corporate Bond Fund


(B) REPURCHASE AGREEMENTS.  The Fund's custodian and other banks acting in a
sub-custodian capacity take 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.

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

The use of foreign currency forward contracts involves, to varying degrees,
elements of market risk in excess of the amount recognized in the Statement of
Assets and Liabilities. The contract amount reflects the extent of the Fund's
involvement in these financial instruments. Risks arise from the possible
movements in the foreign exchange rates underlying these instruments. The
unrealized appreciation on forward contracts reflects the Fund's exposure at
period end to credit loss in the event of a counterparty's failure to perform
its obligations.

(D) SECURITIES LENDING.  The Fund may lend its securities to broker-dealers and
financial institutions. The loans are collateralized by cash or securities at
least equal at all times to the market value of the securities loaned. The Fund
may bear the risk of delay in recovery of, or loss of rights in, the securities
loaned should the borrower of the securities experience financial difficulty.
The Fund receives compensation for lending its securities in the form of fees or
it retains a portion of interest on the investment of any cash received as
collateral. The Fund also continues to receive interest and dividends on the
securities loaned and any gain or loss in the market price of the securities
loaned that may occur during the term of the loan will be for the account of the
Fund. (See Note 7.)

(E) LOAN ASSIGNMENTS, PARTICIPATIONS AND COMMITMENTS.  The Fund invests in loan
assignments and loan participations. Loan assignments and participations are
agreements to make money available (a "commitment") to a borrower in a specified
amount, at a specified rate and within a specified time. Such loan assignments
and participations are typically senior, secured and collateralized in nature.
The Fund records an investment when the borrower withdraws money and records
interest as earned. These loans pay interest at rates which are periodically
reset by reference to a base lending rate plus a spread. These base lending
rates are generally the prime rate offered by a designated U.S. bank or London
InterBank Offered Rate (LIBOR).

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

The Fund assumes the credit risk of the Borrower, the Selling Participant and
any other persons interpositioned between the Fund and the Borrower
("Intermediate Participants"). In the event that the Borrower, Selling
Participant or Intermediate Participants becomes insolvent or enters into
bankruptcy, the Fund may incur certain costs and delays in realizing payments,
or may suffer a loss of principal and/or interest.

Unfunded commitments represent the remaining obligation of the Fund to the
Borrower. At any point in time, up to the maturity date of the issue, the
Borrower may demand the unfunded portion. These unfunded amounts are recorded in
memorandum accounts. (See Note 7.)

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

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

(G) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are
recorded on the ex-dividend date. The Fund intends to declare and pay dividends
monthly and capital gain distributions, if any, annually. 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

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

on their federal tax basis treatment; temporary differences do not require
reclassification.

The following table discloses the current year reclassifications between
accumulated distributions in excess of net investment income and accumulated net
realized loss on investments arising from permanent differences; net assets at
October 31, 2004, are not effected.

           $13,802,361                  $(13,802,361)
</Table>

The reclassifications for the Fund are primarily due to premium amortization
adjustments and foreign currency gain (loss).

(H) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  The Fund records security
transactions on the trade date. Realized gains and losses on security
transactions are determined using the identified cost method. Dividend income is
recognized on the ex-dividend date and interest income is accrued as earned.
Discounts and premiums on securities, other than short-term securities,
purchased for the Fund are accreted and amortized, respectively, on the constant
yield method over the life of the respective securities or, in the case of
callable securities, 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. Income from payment-in-kind securities is recorded
daily based on the effective interest method of accrual.

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

(I) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred except where direct allocations of expenses can be made. Expenses
(other than expenses incurred under the distribution plans) are allocated to
separate classes of shares based upon their relative net asset value on the date
the expenses are incurred. The expenses borne by the Fund, including those of
related parties to the Fund, are shown in the Statement of Operations.

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

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

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

The assets and liabilities are presented at the exchange rates and market values
at the close of the year. The realized and unrealized changes in net assets
arising from fluctuations in exchange rates and market prices of securities are
not separately presented.

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

(K) REDEMPTION FEE.  The Fund imposes a 2.00% redemption fee on redemptions
(including exchanges) of Fund shares made within 60 days of their date of
purchase of Class A, Class B, Class C and Class I shares. The redemption fee is
designed to offset brokerage commissions and other costs associated with
short-term trading and is not assessed on shares acquired through the
reinvestment of dividends or distributions paid by the Fund. The redemption fees
are included in the Statement of Changes in Net Assets' shares redeemed amount
and retained by the Fund.

(L) 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.

NOTE 3 -- FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER AND SUBADVISOR.  New York Life Investment Management LLC ("NYLIM" or
the "Manager"), an indirect wholly-owned subsidiary of New York Life Insurance
Company ("New York Life"), serves as the Fund's manager. The Manager provides
offices, conducts clerical, recordkeeping and bookkeeping services, and keeps
the financial and accounting records required for the Fund. The Manager also
pays the salaries and expenses of all personnel affiliated with the Fund and all
the operational expenses that are not the responsibility of the Fund.

 28   MainStay High Yield Corporate Bond Fund


MacKay Shields LLC (the "Subadvisor"), a registered investment advisor and
indirect wholly-owned subsidiary of New York Life, is responsible for the
day-to-day portfolio management of the Fund.

The Trust, on behalf of the Fund, pays the Manager a monthly fee for services
performed and the facilities furnished at an annual rate of 0.60% of the Fund's
average daily net assets on assets up to $500 million and 0.55% annually on
assets in excess of $500 million. For the year ended October 31, 2004, the
Manager earned from the Fund $25,282,743.

Pursuant to the terms of a Sub-Advisory Agreement between NYLIM and MacKay
Shields, the Manager paid the Subadvisor a monthly fee at an annual rate of
0.30% on assets up to $500 million and 0.275% on assets in excess of $500
million.

(B) DISTRIBUTION AND SERVICE FEES.  The Trust, on behalf of the Fund, has a
Distribution Agreement with NYLIFE Distributors LLC (the "Distributor"), an
indirect wholly-owned subsidiary of New York Life. The Fund, with respect to
each class of shares other than Class I shares, has adopted distribution plans
(the "Plans") in accordance with the provisions of Rule 12b-1 under the 1940
Act. Pursuant to the Class A Plan, the Distributor receives a monthly fee from
the Fund at an annual rate of 0.25% of the average daily net assets of the
Fund's Class A shares, which is an expense of the Class A shares of the Fund for
distribution or service activities as designated by the Distributor. Pursuant to
the Class B and Class C Plans, the Fund pays the Distributor a monthly fee,
which is an expense of the Class B and Class C shares of the Fund, at the annual
rate of 0.75% of the average daily net assets of the Fund's Class B and Class C
shares. The distribution plans provide that the Class B and Class C shares of
the Fund 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 Fund. Class I
shares are not subject to a distribution or service fee.

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

(C) SALES CHARGES.  The Fund was advised by the Distributor that the amount of
sales charges retained on sales of Class A shares was $581,524 for the year
ended October 31, 2004. The Fund was also advised that the Distributor retained
contingent deferred sales charges for redemption of Class A, Class B and Class C
shares of $186,789, $3,362,137 and $165,719, respectively, for the year ended
October 31, 2004.

(D) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT.  NYLIM
Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's
transfer, dividend disbursing and shareholder servicing agent. NYLIM Service has
entered into an agreement with Boston Financial Data Services ("BFDS") pursuant
to which BFDS will perform certain of the services for which NYLIM Service is
responsible. Transfer agent expenses for the year ended October 31, 2004,
amounted to $6,027,712.

(E) NON-INTERESTED TRUSTEES.  Non-Interested Trustees are paid an annual
retainer fee of $45,000, $2,000 for each Board meeting, $1,000 for each
Committee meeting and $500 for each Valuation Subcommittee telephonic meeting
attended plus reimbursement for travel and out-of-pocket expenses. The Lead
Non-Interested Trustee is also paid an annual retainer fee of $20,000. The Audit
Committee Chairman receives an additional $2,000 for each meeting of the Audit
Committee attended and the Chairpersons of the Brokerage Committee, Operations
Committee and Performance Committee each receive an additional $1,000 for each
meeting of the Brokerage Committee, Operations Committee and Performance
Committee attended, respectively. In addition, each Non-Interested Trustee is
paid $1,000 for attending meetings of the Non-Interested Trustees held in
advance of or in connection with Board/Committee meetings. The Trust allocates
trustees fees in proportion to the net assets of the respective Funds. Thus the
High Yield Corporate Bond Fund only pays a portion of the fees identified above.

(F) OTHER.  Fees for the cost of legal services, included in Professional fees
as shown on the Statement of Operations, provided to the Fund by the Office of
the General Counsel of NYLIM, amounted to $133,867 for the year ended October
31, 2004.

The Fund pays the Manager a monthly fee for recordkeeping services provided
under the Accounting Agreement at the annual rate of 1/20 of 1% for the first
$20 million of average monthly net assets, 1/30 of 1% of the next $80 million of
average monthly net assets and 1/100 of 1% of any amount in excess of $100
million of average monthly net assets. Fees for recordkeeping services provided
to the Fund by the Manager amounted to $481,807 for the year ended October 31,
2004.

NOTE 5 -- RESTRICTED SECURITIES:

A restricted security is a security which has been purchased through a private
offering and cannot be resold to the general public without prior registration
under the Securities Act of 1933 (the "1933 Act"). The Fund does not have the
right to demand that such securities be registered. Disposal of these securities
may involve time-consuming negotiations and expense, and prompt sale at an
acceptable price may be difficult.

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

NOTE 6 -- FEDERAL INCOME TAX:

As of October 31, 2004, the components of accumulated loss on a tax basis were
as follows:

<Table>
<Caption>
  UNDISTRIBUTED    ACCUMULATED                       TOTAL
    ORDINARY       CAPITAL AND      UNREALIZED    ACCUMULATED
     INCOME        OTHER LOSSES    APPRECIATION       LOSS
                                        
   $7,092,816     $(677,839,388)    $62,970,421  $(607,776,151)
</Table>

The difference between book-basis and tax-basis unrealized appreciation is
primarily due to wash sale deferrals, premium amortization adjustments, bond
reorganizations and interest write-offs.

At October 31, 2004, for federal income tax purposes, capital loss carryforwards
of $677,839,388 were available as shown in the table below, to the extent
provided by the regulations to offset future realized gains 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.

funds pay a commitment fee, at an annual rate of .075% of the average commitment
amount, regardless of usage, to The Bank of New York, which acts as agent to the
syndicate. Such commitment fees are allocated among the funds based upon net
assets and other factors. Interest on any revolving credit loan is charged based
upon the Federal Funds Advances rate. There were no borrowings on the line of
credit during the year ended October 31, 2004.

NOTE 11 -- OTHER MATTERS:

NYLIM and mutual funds that NYLIM advises have received requests for information
from various government authorities and regulatory bodies regarding market
timing, late trading, operations, fees, expenses, and other matters. NYLIM and
the funds it advises are cooperating fully in responding to these requests. As
reported in response to those requests for information, NYLIM was previously
party to agreements with certain registered representatives of broker-dealers
relating to the level of trading by clients or customers of those registered
representatives in shares of certain funds of the Trust. NYLIM is continuing to
review what effect, if any, transactions under these agreements may have had on
the funds, and will continue to apprise the Board of Trustees of such
information. NYLIM does not believe at this time that such trading had any
material effect on the funds' financial statements or their shareholders. To
date, substantially all of the costs associated with these and other regulatory
matters have been borne by NYLIM. Except as described below, neither NYLIM nor
the funds advised by it have any reason to believe that they have been targeted
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.
Discussions have been held with the SEC concerning a possible resolution of this
matter. These discussions are continuing, but there can be no assurance at this
time as to the outcome of these efforts.

NOTE 12 -- CHANGE IN INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM (UNAUDITED):

On March 8, 2004, KPMG LLP ("KPMG") was selected as the Trust's independent
auditor for the 2004 fiscal year. The selection of KPMG was recommended by the
Trust's Audit Committee, comprised of all Non-Interested Trustees, and was
approved by the Trust's Board of Trustees.

The predecessor independent auditor's reports on the Trust's financial
statements for the period ended October 31, 2003 and year ended December 31,
2002 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 periods, and through the date of engagement of KPMG, there
were no disagreements between 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 periods.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Trustees and Shareholders of
The MainStay Funds:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of the MainStay High Yield Corporate Bond Fund
(the "Fund"), one of the funds constituting The MainStay Funds, as of October
31, 2004, and the related statement of operations, statement of changes in net
assets and the financial highlights for the year or period then ended. These
financial statements and financial highlights are the responsibility of the
Fund's management. Our responsibility is to express an opinion on these
financial statements and financial highlights based on our audit. The statement
of changes in net assets for the period ended October 31, 2003 and the year
ended December 31, 2002, and the financial highlights for the periods presented
through October 31, 2003, were audited by other auditors, whose report dated
December 18, 2003 expressed an unqualified opinion thereon.

We conducted our audit in accordance with the Standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
also includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2004 by correspondence with the custodian and
brokers. As to securities purchased or sold but not yet received or delivered,
we performed other appropriate auditing procedures. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
MainStay High Yield Corporate Bond Fund of The MainStay Funds as of October 31,
2004, the results of its operations, the changes in its net assets and its
financial highlights for the year or period then ended, in conformity with U.S.
generally accepted accounting principles.

MESSAGE FROM
THE PRESIDENT

During the 12 months ended October 31, 2004, the U.S. stock market advanced, but
its pace and direction were by no means steady. Small- and mid-capitalization
stocks tended to outperform large-cap issues, and value stocks generally
outperformed growth stocks.

Economic activity, as measured by gross domestic product, increased from 4.2% in
the fourth quarter of 2003 to 4.5% in the first quarter of 2004. The pace of
economic growth slowed to 3.3% in the second quar-
ter of 2004, and according to preliminary estimates from the Bureau of Economic
Analysis, gross domestic product grew at a seasonally adjusted annual rate of
3.9% in the third quarter of 2004.

Interest rates began the reporting period at a low 1.00%. In June 2004, the
Federal Open Market Committee responded to expanding output and improved labor
markets by raising the targeted federal funds rate by 25 basis points. Similar
moves in August and September brought the targeted federal funds rate to 1.75%.
In its September 2004 release, the Federal Open Market Committee affirmed its
belief that monetary policy remained accommodative.

Despite rising interest rates, bond markets generally advanced. High-yield bonds
and emerging-market debt were particularly strong. The U.S. dollar declined
relative to most other currencies, which helped U.S. exporters.

In pursuing its investment objective, each MainStay Fund consistently seeks to
apply a well-defined investment process in all market environments. We believe
that a consistent, disciplined investment approach can help investors make more
prudent and practical decisions regarding their investments.

In the report that follows, you'll find additional information about the market
forces, investment decisions, and individual securities that affected your
MainStay Fund during the 12 months ended October 31, 2004. We thank you for
investing with us, and we look forward to many years of continued service in
your behalf.
Sincerely,
/s/ GARY E. WENDLANDT
Gary E. Wendlandt

President

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

Questions answered by portfolio managers Joseph Portera and Gary Goodenough of
MacKay Shields LLC

WHAT MAJOR FACTORS INFLUENCED THE INTERNATIONAL BOND MARKETS DURING THE 12
MONTHS ENDED OCTOBER 31, 2004?

In the early part of the reporting period, geopolitical risks buoyed government
bond markets. Few investors believed that the global economy was growing fast
enough to warrant higher interest rates soon. With improving economic data from
the United States, Japan, and China, however, rising rates became inevitable.
Indeed, for most of the period, the United Kingdom and Australian monetary
authorities were aggressively raising short-term interest rates. They were
joined by the U.S. in late June.

DID CURRENCY MOVEMENTS HAVE A MAJOR IMPACT ON BOND VALUES?

Yes, they did. The U.S. dollar was under pressure during most of the 12-month
period, and nearly every major currency rallied relative to the dollar. In fact,
the U.S. dollar reached new lows against the euro during the reporting period.
As the U.S. dollar continued to weaken, The Bank of Japan felt compelled to
intervene and spent over 100 billion dollars to keep the yen from rising in the
first few months of 2004.

For the 12-month period, the return for the Citigroup Non-U.S. Dollar World
Government Bond Index(1) was less than 5% in local currency terms, but once
currency movements were taken into account, the Index returned more than 12% in
U.S. dollar terms.

HOW DID VARIOUS MARKETS PERFORM?

Among developed markets, the best performer was Norway, which returned more than
8% in local currency terms for the 12-month reporting period. The U.K., Canada,
Australia, and Sweden each had 12-month returns greater than 7% in local
currency terms. The worst performer was Japan, which was up only 1.5% in local
currency terms for the reporting period.

CAN YOU BRIEFLY DESCRIBE THE FUND'S INVESTMENT APPROACH?

The Fund normally invests at least 80% of its assets in debt securities.
Normally, the Fund invests in debt securities of foreign governments, agencies,
and supranational organizations, and secondarily in debt securities of corporate
issuers located in a variety of developed and emerging-market countries,
primarily outside the U.S. The Fund's principal investments also include
high-yield debt securities, with certain limitations on credit quality. We also
invest in mortgage-related and asset-backed securities. In implementing this
strategy, we seek to identify opportunities based on our assessments of
countries, currencies, and individual securities. We may consider currency
exchange rates, interest rates, inflation, relative economic growth, and
governmental policies. The Fund may also buy and sell currency on a spot basis,
enter into foreign currency forward contracts, and buy and sell foreign-currency
options.

WHAT AFFECT DID CURRENCY POSITIONING HAVE ON FUND RESULTS DURING THE REPORTING
PERIOD?

Currency positioning was the major reason for the Fund's underperformance versus
its peer group for the reporting period. Defensive currency management and
fundamental analysis led us to underweight foreign currency in the portfolio,
specifically but not solely the Japanese yen.

WHAT INFLUENCE DID COUNTRY ALLOCATION HAVE ON FUND PERFORMANCE?

During the reporting period we made significant asset shifts among international
bond markets, based primarily on our expectations regarding interest rates and
currency movements. We reduced the portfolio's exposure to Canadian-dollar bonds
from 8% to 2%. We redeployed some of those assets into U.K. bonds, increasing
the Fund's position in the U.K. market from 8% to 10%. In so doing, we increased
the duration within the U.K. market significantly, on the belief that U.K.
monetary authorities were nearing the end of their interest-rate tightening. We
also increased the Fund's exposure in core European bonds from just under 53% to
56% of net assets. Within the Scandinavian markets, we shifted from a 3% to 5%
exposure in Danish krone denominated bonds and established a position in Norway.
Norway represents a special opportunity since its economy is so heavily weighted
in the oil sector. We believed that the Norwegian krone would likely outperform
the euro as oil prices continued to rise. Indeed, after

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.
High-yield securities ("junk bonds") are generally considered speculative
because they present a greater risk of loss than higher-quality debt securities
and may be subject to greater price volatility. The Fund is nondiversified. By
concentrating in a smaller number of investments, the Fund's risk is increased
because each investment has a greater effect on the Fund's performance. 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.

we purchased the Norwegian bonds in early February, the Norwegian krone
appreciated against the U.S. dollar and the euro. We shifted the portfolio's
duration risk away from Canada (because of Canada's high correlation with the
U.S. market) and into markets that we believed would outperform in a rising U.S.
interest-rate environment. This strategy made a positive contribution to the
Fund's results.

We also increased the Fund's exposure to Japan from 7% to 9% during the
reporting period. With Japanese short-term rates close to zero, however, we
focused on investments in corporate and emerging names rather than on government
bonds.

HOW DID EMERGING-MARKET DEBT PERFORM?

The Fund's holdings in emerging-market debt performed well over the 12-month
reporting period, despite higher U.S. interest rates. There was a sell-off in
the emerging-market sector during the second quarter of 2004, but
emerging-market debt subsequently recovered and posted impressive returns as
yield spreads to U.S. Treasuries narrowed. On average, the yield spread of
emerging-market debt to U.S. Treasuries narrowed 60 basis points from April 2004
to the end of October 2004. The Fund's exposure to this sector remained
virtually unchanged at approximately 12% of net assets.

DID DURATION POSITIONING AFFECT FUND PERFORMANCE DURING THE REPORTING PERIOD?

The Fund's excess return derives primarily from asset or country allocation and
currency selection, not from duration alone. Duration positioning in the Fund is
largely a residual of asset selection. The portfolio as a whole usually does not
stray more than 10% from the duration of the benchmark. Throughout the 12-month
period, the Fund's duration remained between 93% and 95% of the duration of the
Citigroup Non-U.S. Dollar World Government Bond Index, so the impact of duration
on relative performance was relatively modest. We believe that the Fund's
decision to shift duration risk away from Canada had a positive impact on
performance. Our decision to increase duration in the U.K. market may help
strengthen performance relative to the U.S. bond market if interest rates
continue to rise in the United States.

WHAT DO YOU ANTICIPATE GOING FORWARD?

We believe that the U.S. dollar's prospects remain dim, as the U.S. current
account and budget deficits will require massive amounts of foreign capital
funding. For this reason, we intend to shift toward additional foreign-currency
exposure. In particular, we are likely to look for opportunities to increase
exposure to the euro going forward.

With prospects for higher U.S. interest rates still intact, we intend to focus
our efforts on finding investment opportunities in markets whose interest-rate
cycle is not synchronized with that of the U.S. We believe Europe and the U.K.
may offer the best relative-value opportunities and that these markets will
likely remain among the most heavily weighted in the Fund. In our view,
emerging-market debt remains attractive as well, and we expect continued
outperformance from this sector relative to U.S. Treasuries.

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

At a meeting on September 21, 2004, the Board of Trustees of The MainStay Funds
(the "Trust") approved an Agreement and Plan of Reorganization whereby all of
the assets and liabilities of the Fund will be transferred to the MainStay
Global High Income Fund (a series of the Trust) in exchange for shares of
MainStay Global High Income Fund (the "Reorganization"). Under this Agreement,
the Fund would be completely liquidated after the Reorganization. A meeting of
shareholders of the Fund has been scheduled for January 18, 2005 in order to
vote on the proposed Reorganization. Should shareholders approve a
Reorganization, it is scheduled to be effective on or about the close of
business on January 21, 2005.

NOTES TO FINANCIAL STATEMENTS

NOTE 1 -- ORGANIZATION AND BUSINESS:

The MainStay Funds (the "Trust") was organized on January 9, 1986 as a
Massachusetts business trust. The Trust is registered under the Investment
Company Act of 1940, as amended (the "1940 Act"), as an open-end management
investment company and comprises twenty-two funds (collectively referred to as
the "Funds"). These financial statements and notes relate only to MainStay
International Bond Fund (the "Fund").

The Fund currently offers three classes of shares. Class A shares, whose
distribution commenced on January 3, 1995, 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 within one year of purchase of Class C
shares. Distribution of Class B shares and Class C shares commenced on September
13, 1994 and September 1, 1998, respectively. Class A shares, Class B shares and
Class C shares bear the same voting (except for issues that relate solely to one
class), dividend, liquidation and other rights and conditions except that the
Class B shares and Class C shares are subject to higher distribution fee rates.
Each class of shares bears distribution and/or service fee payments under a
distribution plan pursuant to Rule 12b-1 under the 1940 Act.

The Fund's investment objective is to seek to provide a competitive overall
return commensurate with an acceptable level of risk by investing primarily in a
portfolio of non-U.S. (primarily government) debt securities. MainStay
International Bond Fund is "non-diversified," which means that it may invest a
greater percentage of its assets than diversified funds in a particular issuer.
This may make it more susceptible than diversified funds to risks associated
with an individual issuer, and to single economic, political or regulatory
occurrences.

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

The Fund invests in high yield securities (sometimes called "junk bonds"), which
are generally considered speculative because they present a greater risk of
loss, including default, than higher quality debt securities. These securities
pay a premium -- a high interest rate or yield -- because of the increased risk
of loss. These securities can also be subject to greater price volatility.

NOTE 2 -- SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with generally accepted
accounting principles and follows the significant accounting policies described
below.

(A) SECURITIES VALUATION.  Debt securities are valued at prices supplied by a
pricing agent selected by the Fund's Manager, whose prices reflect broker/dealer
supplied valuations and electronic data processing techniques if those prices
are deemed by the Fund's Manager to be representative of market values at the
regular close of business of the New York Stock Exchange. 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. Securities for which market
quotations are not readily available are valued by methods deemed by the Board
of Trustees to represent fair value. Reasons for which securities may be valued
in this manner include, but are not limited to, trading for a security has been
halted or suspended, a security has been de-listed from a national exchange, or
trading on a security's primary market is temporarily closed at a time when
under normal conditions it would be open. The Fund did not hold securities at
October 31, 2004, that were valued in such manner. Foreign currency forward
contracts are valued at their fair market values determined on the basis of the
mean between the last current bid and asked prices based on dealer or exchange
quotations.

Certain events may occur between the time that foreign markets close, on which
securities held by the Fund principally trade, and the time at which the Fund's
NAV is calculated. These events may include, but are not limited to, situations
relating to a single issue in a market sector, significant fluctuations in U.S.
or foreign markets, natural disasters, armed conflicts, governmental actions or
other developments not tied directly to the securities markets. Should the
Manager or Subadvisor conclude that such events may have affected the accuracy
of the last price reported on the local foreign market, the Manager or
Subadvisor may, pursuant to procedures adopted by the Fund, adjust the value of
the local price to reflect the impact on the price of such securities as a
result or such events.

(B) FOREIGN CURRENCY FORWARD CONTRACTS.  A foreign currency forward contract is
an agreement to buy or sell currencies of different countries on a specified
future

 18   MainStay International Bond Fund


date at a specified rate. During the period the forward contract is open,
changes in the value of the contract are recognized as unrealized gains or
losses by "marking to market" such contract on a daily basis to reflect the
market value of the contract at the end of each day's trading. When the forward
contract is closed, the Fund records a realized gain or loss equal to the
difference between the proceeds from (or cost of) the closing transaction and
the Fund's basis in the contract. The Fund may enter into foreign currency
forward contracts primarily to hedge its foreign currency denominated
investments and receivables and payables against adverse movements in future
foreign exchange rates or to try to enhance the Fund's returns.

The use of foreign currency forward contracts involves, to varying degrees,
elements of market risk in excess of the amount recognized in the Statement of
Assets and Liabilities. The contract amount reflects the extent of the Fund's
involvement in these financial instruments. Risks arise from the possible
movements in the foreign exchange rates underlying these instruments. The
unrealized appreciation on forward contracts reflects the Fund's exposure at
period end to credit loss in the event of a counterparty's failure to perform
its obligations.

(C) PURCHASED AND WRITTEN OPTIONS.  The Fund may write covered call and put
options on its 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 cancelled in closing purchase
transactions are added to the proceeds or netted against the amount paid on the
transaction to determine the realized gain or loss. By writing a covered call
option, a Fund foregoes in exchange for the premium 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.

The Fund may purchase call and put options on its portfolio securities or
foreign currencies. The Fund may purchase call options to protect against an
increase in the price of the security or foreign currency it anticipates
purchasing or to seek to enhance returns. The Fund may purchase put options on
its securities or foreign currencies to protect against a decline in the value
of the security or foreign currency or to close out covered written put
positions. Risks may arise from an imperfect correlation between the change in
market value of the securities or foreign currencies held by the Fund and the
prices of options relating to the securities or foreign currencies purchased or
sold by the Fund and from the possible lack of a liquid secondary market for an
option. The maximum exposure to loss for any purchased option is limited to the
premium initially paid for the option.

(D) LOAN PARTICIPATIONS AND COMMITMENTS.  The Fund invests in loan
participations. Loan participations are agreements to make money available (a
"commitment") to a borrower in a specified amount, at a specified rate and
within a specified time. Such loan participations are typically senior, secured
and collateralized in nature. The Fund records an investment when the borrower
withdraws money and records interest as earned. These loans pay interest at
rates which are periodically reset by reference to a base lending rate plus a
spread. These base lending rates are generally the prime rate offered by a
designated U.S. bank or London InterBank Offered Rate (LIBOR).

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

The Fund assumes the credit risk of the Borrower, the Selling Participant and
any other persons interpositioned between the Fund and the Borrower
("Intermediate Participants"). In the event that the Borrower, Selling
Participant or Intermediate Participants becomes insolvent or enters into
bankruptcy, the Fund may incur certain costs and delays in realizing payments,
or may suffer a loss of principal and/or interest.

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

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

(F) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are
recorded on the ex-dividend date. The Fund intends to declare and pay dividends
monthly and capital gain distributions, if any, annually. 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.

The following table discloses the current year reclassifications between
accumulated undistributed net investment income and accumulated net realized
loss on investments and written option transactions; net assets at October 31,
2004, are not effected.

     $60,614                  $(60,614)
</Table>

The reclassifications for the Fund are primarily due to foreign currency gain
(loss).

(G) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  The Fund records security
transactions on the trade date. Realized gains and losses on security
transactions are determined using the identified cost method. Interest income is
accrued as earned. Discounts and premiums on securities, other than short-term
securities, purchased for the Fund 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.

The investment income, and realized and unrealized gains and losses on
investments of the 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.

(H) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred except where direct allocations of expenses can be made. Expenses
(other than expenses incurred under the distribution plans) are allocated to
separate classes of shares based upon their relative net asset value on the date
the expenses are incurred. The expenses borne by the Fund, including those of
related parties to the Fund, are shown in the Statement of Operations.

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

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

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

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

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

(J) 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.

NOTE 3 -- FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER AND SUBADVISOR.  New York Life Investment Management LLC ("NYLIM" or
the "Manager"), an indirect wholly-owned subsidiary of New York Life Insurance
Company ("New York Life"), serves as the Fund's manager. The Manager provides
offices, conducts clerical, recordkeeping and bookkeeping services, and keeps
the financial and accounting records required for the Fund. The Manager also
pays the salaries and expenses of all personnel affiliated with the Fund and all
the operational expenses that are not the responsibility of the Fund. MacKay
Shields LLC (the "Subadvisor"), a registered investment advisor and indirect
wholly-owned subsidiary of New York Life, is responsible for the day-to-day
portfolio management of the Fund.

Through July 31, 2004, the Trust, on behalf of the Fund, paid the Manager a
monthly fee for services performed and the facilities furnished at an annual
rate of 0.70% of the Fund's average daily net assets. The Manager had
voluntarily agreed to reimburse the expenses of the Fund to the extent that
operating expenses would exceed on an annualized basis 1.70%, 2.45% and 2.45% of
the average daily net assets of the Class A, Class B and Class C shares,
respectively. Effective August 1, 2004, the Trust pays the Manager an annual
rate of 0.70% of the Fund's average daily net assets on assets up to $500
million and 0.65% on assets over $500 million and effective on that date NYLIM
has voluntarily agreed to waive its management fee by

 20   MainStay International Bond Fund


0.10% of the Fund's average net assets. In addition, effective December 1, 2004,
NYLIM has voluntarily agreed to reimburse the expenses of the Fund to the extent
that operating expenses would exceed on an annualized basis 1.40%, 2.15% and
2.15% of the average daily net assets of the Class A, Class B and Class C
shares, respectively. For the year ended October 31, 2004, the Manager earned
from the Fund $256,577, waived $9,421 and reimbursed the Fund $64,943. The fees
waived and reimbursed by the Manager total $74,364.

Pursuant to the terms of a Sub-Advisory Agreement between NYLIM and
MacKay-Shields, the Manager paid the Subadvisor a monthly fee at an annual rate
of 0.45% of the average daily net assets of the Fund. To the extent that the
Manager has agreed to reimburse Fund expenses, the Subadvisor has voluntarily
agreed to do so proportionately.

(B) DISTRIBUTION AND SERVICE FEES.  The Trust, on behalf of the Fund, has a
Distribution Agreement with NYLIFE Distributors LLC. (the "Distributor"), an
indirect wholly-owned subsidiary of New York Life. The Fund, with respect to
each class of shares, has adopted distribution plans ("the Plans") in accordance
with the provisions of Rule 12b-1 under the 1940 Act. Pursuant to the Class A
Plan, the Distributor receives a monthly fee from the Fund at an annual rate of
0.25% of the average daily net assets of the Fund's Class A shares, which is an
expense of the Class A shares of the Fund for distribution or service activities
as designated by the Distributor. Pursuant to the Class B and Class C Plans, the
Fund pays the Distributor a monthly fee, which is an expense of the Class B and
Class C shares of the Fund, at the annual rate of 0.75% of the average daily net
assets of the Fund's Class B and Class C shares. The distribution plans provide
that the Class B and Class C shares of the Fund 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 Fund.

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

(C) SALES CHARGES.  The Fund was advised by the Distributor that the amount of
sales charges retained on sales of Class A shares was $4,151 for the year ended
October 31, 2004. The Fund was also advised that the Distributor retained
contingent deferred sales charges on redemptions of Class A, Class B and Class C
shares of $59, $34,167 and $7,713, respectively, for the year ended October 31,
2004.

(D) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT.  NYLIM
Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's
transfer, dividend disbursing and shareholder servicing agent. NYLIM Service has
entered into an agreement with Boston Financial Data Services ("BFDS") pursuant
to which BFDS will perform certain of the services for which NYLIM Service is
responsible. Transfer agent expense for the year ended October 31, 2004 amounted
to $163,178.

(E) NON-INTERESTED TRUSTEES.  Non-Interested Trustees are paid an annual
retainer fee of $45,000, $2,000 for each Board meeting, $1,000 for each
Committee meeting and $500 for each Valuation Subcommittee telephonic meeting
attended plus reimbursement for travel and out-of-pocket expenses. The Lead
Non-Interested Trustee is also paid an annual retainer fee of $20,000. The Audit
Committee Chairman receives an additional $2,000 for each meeting of the Audit
Committee attended and the Chairpersons of the Brokerage Committee, Operations
Committee and Performance Committee each receive an additional $1,000 for each
meeting of the Brokerage Committee, Operations Committee and Performance
Committee attended, respectively. In addition, each Non-Interested Trustee is
paid $1,000 for attending meetings of the Non-Interested Trustees held in
advance of or in connection with Board/Committee meetings. The Trust allocates
trustees fees in proportion to the net assets of the respective Funds. Thus the
International Bond Fund only pays a portion of the fees identified above.

(F) CAPITAL.  At October 31, 2004, NYLIFE Distributors held shares of Class A
with a value of $7,429,453 which represents 43.9% of the Class A net assets and
21.1% of total fund net assets at year end.

(G) OTHER.  Fees for the cost of legal services, included in Professional fees
as shown in the Statement of Operations, provided to the Fund by the Office of
the General Counsel of NYLIM amounted to $1,116 for the year ended October 31,
2004.

The Fund pays the Manager a monthly fee for recordkeeping services provided
under the Accounting Agreement at the annual rate of 1/20 of 1% for the first
$20 million of average monthly net assets, 1/30 of 1% of the next $80 million of
average monthly net assets and 1/100 of 1% of any amount in excess of $100
million of average monthly net assets. Fees for recordkeeping services provided
to the Fund by the Manager amounted to $15,549 for the year ended October 31,
2004.

NOTE 4 -- CUSTODIAN:

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

NOTE 5 -- RESTRICTED SECURITIES:

A restricted security is a security which has been purchased through a private
offering and cannot be resold to the general public without prior registration
under the Securities Act of 1933 (the "1933 Act"). The Fund does not have the
right to demand that such securities be registered. Disposal of these securities
may involve time-consuming negotiations and expense, and prompt sale at an
acceptable price may be difficult.

Restricted security held at October 31, 2004:

NOTE 6 -- FEDERAL INCOME TAX:

As of October 31, 2004, the components of accumulated gain on a tax basis were
as follows:

<Table>
<Caption>
                   ACCUMULATED
  UNDISTRIBUTED    CAPITAL AND                     TOTAL

  $2,805,078       $(849,404)    $2,055,793     $4,011,467
</Table>

The difference between book-basis and tax-basis unrealized appreciation is
primarily due to wash sale deferrals, mark-to-market of foreign currency forward
transactions and straddle deferrals.

At October 31, 2004, for federal income tax purposes, capital loss carryforwards
of $849,404 were available as shown in the table below, to the extent provided
by the regulations, to offset future realized gains of the Fund through the
years indicated. 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 8 -- PURCHASES AND SALES OF SECURITIES (IN 000'S):

During the year ended October 31, 2004, purchases and sales of securities, other
than short-term securities, were $22,415 and $19,195, respectively.

NOTE 9 -- LINE OF CREDIT:

The Fund and certain affiliated funds maintain a line of credit of $160,000,000
with a syndicate of banks in order to secure a source of funds for temporary
purposes to meet unanticipated or excessive shareholder redemption requests. The

NOTE 11 -- SPECIAL MEETING OF SHAREHOLDERS:

The Board of Trustees of the Trust has called a special meeting of Shareholders
("Special Meeting") of the Fund,

                                                    www.mainstayfunds.com     23

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

scheduled to be held on January 18, 2005. At the Special Meeting, shareholders
will vote on a proposed reorganization of the Fund into the MainStay Global High
Income Fund, also a series of the Trust.

NOTE 12 -- OTHER MATTERS:

NYLIM and mutual funds that NYLIM advises have received requests for information
from various government authorities and regulatory bodies regarding market
timing, late trading, operations, fees, expenses, and other matters. NYLIM and
the funds it advises are cooperating fully in responding to these requests. As
reported in response to those requests for information, NYLIM was previously
party to agreements with certain registered representatives of broker-dealers
relating to the level of trading by clients or customers of those registered
representatives in shares of certain funds of the Trust. NYLIM is continuing to
review what effect, if any, transactions under these agreements may have had on
the funds, and will continue to apprise the Board of Trustees of such
information. NYLIM does not believe at this time that such trading had any
material effect on the funds' financial statements or their shareholders. To
date, substantially all of the costs associated with these and other regulatory
matters have been borne by NYLIM. Except as described below, neither NYLIM nor
the funds advised by it have any reason to believe that they have been targeted
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.
Discussions have been held with the SEC concerning a possible resolution of this
matter. These discussions are continuing, but there can be no assurance at this
time as to the outcome of these efforts.

NOTE 13 -- CHANGE IN INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM (UNAUDITED):

On March 8, 2004, KPMG LLP ("KPMG") was selected as the Trust's independent
auditor for the 2004 fiscal year. The selection of KPMG was recommended by the
Trust's Audit Committee, comprised of all Non-Interested Trustees, and was
approved by the Trust's Board of Trustees.

The predecessor independent auditor's reports on the Trust's financial
statements for the period ended October 31, 2003 and year ended December 31,
2002 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 periods, and through the date of engagement of KPMG, there
were no disagreements between the Trust and the predecessor independent auditor
on any matter of accounting principals 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 periods.

 24   MainStay International Bond Fund


REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Trustees and Shareholders of
The MainStay Funds:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of the MainStay International Bond Fund (the
"Fund"), one of the funds constituting The MainStay Funds, as of October 31,
2004, and the related statement of operations, statement of changes in net
assets and the financial highlights for the year then ended. These financial
statements and financial highlights are the responsibility of the Fund's
management. Our responsibility is to express an opinion on these financial
statements and financial highlights based on our audit. The statement of changes
in net assets for the period ended October 31, 2003 and the year ended December
31, 2002, and the financial highlights for the periods presented through October
31, 2003, were audited by other auditors, whose report dated December 18, 2003
expressed an unqualified opinion thereon.

We conducted our audit in accordance with the Standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
also includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2004 by correspondence with the custodian and
brokers. As to securities purchased or sold but not yet received or delivered,
we performed other appropriate auditing procedures. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
MainStay International Bond Fund of The MainStay Funds as of October 31, 2004,
the results of its operations, the changes in its net assets and its financial
highlights for the year then ended, in conformity with U.S. generally accepted
accounting principles.

MESSAGE FROM
THE PRESIDENT

During the 12 months ended October 31, 2004, the U.S. stock market advanced, but
its pace and direction were by no means steady. Small- and mid-capitalization
stocks tended to outperform large-cap issues, and value stocks generally
outperformed growth stocks.

Economic activity, as measured by gross domestic product, increased from 4.2% in
the fourth quarter of 2003 to 4.5% in the first quarter of 2004. The pace of
economic growth slowed to 3.3% in the second quar-
ter of 2004, and according to preliminary estimates from the Bureau of Economic
Analysis, gross domestic product grew at a seasonally adjusted annual rate of
3.9% in the third quarter of 2004.

Interest rates began the reporting period at a low 1.00%. In June 2004, the
Federal Open Market Committee responded to expanding output and improved labor
markets by raising the targeted federal funds rate by 25 basis points. Similar
moves in August and September brought the targeted federal funds rate to 1.75%.
In its September 2004 release, the Federal Open Market Committee affirmed its
belief that monetary policy remained accommodative.

Despite rising interest rates, bond markets generally advanced. High-yield bonds
and emerging-market debt were particularly strong. The U.S. dollar declined
relative to most other currencies, which helped U.S. exporters.

In pursuing its investment objective, each MainStay Fund consistently seeks to
apply a well-defined investment process in all market environments. We believe
that a consistent, disciplined investment approach can help investors make more
prudent and practical decisions regarding their investments.

In the report that follows, you'll find additional information about the market
forces, investment decisions, and individual securities that affected your
MainStay Fund during the 12 months ended October 31, 2004. We thank you for
investing with us, and we look forward to many years of continued service in
your behalf.
Sincerely,
/s/ GARY E. WENDLANDT

Gary E. Wendlandt

President

Performance tables and graphs do not reflect the deduction of taxes that a
shareholder would pay on distributions or Fund-share redemptions. Total returns
reflect change in share price, reinvestment of dividend and capital-gain
distributions, and maximum applicable sales charges explained in this paragraph.
The graphs assume an initial investment of $10,000 and reflect the deduction of
all sales charges that would have applied for the period of investment. Class A
shares are sold with a maximum initial sales charge of 5.5% and an annual 12b-1
fee of .25%. Class B shares are sold with no initial sales charge, are subject
to a contingent deferred sales charge (CDSC) of up to 5% if redeemed within the
first six years of purchase, and have an annual 12b-1 fee of 1.00%. Class C
shares are sold with no initial sales charge, are subject to a CDSC of 1% if
redeemed within one year of purchase, and have an annual 12b-1 fee of 1.00%.
Class I shares are sold with no initial sales charge or CDSC, have no annual
12b-1 fee, and are generally available to corporate and institutional investors
with a minimum initial investment of $5 million. Class R1 shares are sold with
no initial sales charge or CDSC, and have no annual 12b-1 fee. Class R2 shares
are sold with no initial sales charge or CDSC, and have an annual 12b-1 fee of
..25%. Class R1 and R2 shares are available only through corporate-sponsored
retirement programs, which include certain minimum program requirements. From
inception (9/13/94) through 12/31/94 (for Class A, first offered 1/3/95),
8/31/98 (for Class C, first offered 9/1/98), and 12/31/03 (for Class I, R1, and
R2, first offered 1/2/04), performance of Class A, C, I, R1, and R2 shares
includes the historical performance of Class B shares adjusted to reflect the
respective applicable sales charge (or CDSC) and fees and expenses for Class A,
C, I, R1, and R2 shares.

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

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 data 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 Rupal J. Bhansali of MacKay Shields LLC

CAN YOU BRIEFLY DESCRIBE THE FUND'S INVESTMENT APPROACH?

The Fund seeks to generate superior risk-adjusted returns by investing in
quality companies that we believe are currently undervalued. The Fund normally
invests at least 80% of its assets in equity securities of issuers, wherever
organized, who do business mainly outside the United States. Investments will be
made in a variety of countries with established economies as well as
emerging-market countries that we believe present favorable opportunities. In
implementing this strategy, we utilize a bottom-up, stock-picking investment
discipline. Proprietary quantitative and qualitative tools are used to identify
attractive companies. In-depth, original fundamental research is performed on
identified companies to assess their business and investment prospects.
Particular attention is paid to cash flow, return on invested capital, and
management's demonstrated ability to create shareholder value. Portfolios are
constructed by combining securities with low correlation. Quantitative tools are
used for risk control at the portfolio level. Country allocations in the
portfolio are a result of the bottom up, stock selection process. To reduce
risk, an attempt is made at the portfolio level to stay within a reasonable
range of the key constituents of the benchmark, unless the stock selection
process strongly argues against it.

WHAT MAJOR FACTORS INFLUENCED INTERNATIONAL EQUITIES DURING THE ONE YEAR
REPORTING PERIOD ENDED OCTOBER 31, 2004?

The international equity markets generated strong returns during the reporting
period. In Japan, both the government and the central bank officially maintain
that the economy is on course to enter a sustainable growth path. For this
optimistic scenario to occur, we believe that the strength seen in the corporate
sector needs to find its way to consumers. Household incomes, however, have
remained weak. In Europe, the economic news has been mixed. The euro rose
sharply versus the U.S. dollar and the European Central Bank has not expressed
concerns about the currency's strength. We believe that the European Central
Bank is content to let the euro appreciate, which could reduce pricing
pressures. This scenario, however, would likely have an adverse effect on the
region's exporters. During the reporting period, growth in U.S. corporate
profits, an increase in commodity prices, and the decline of the U.S. dollar
versus most major currencies have ignited inflation fears. During the 12 months
ended October 31, 2004, the Federal Open Market Committee raised the targeted
federal funds rate from 1.00% to 1.75%, and we anticipate rate hikes to continue
well into 2005.

WHAT WERE THE STRONGEST AND WEAKEST AREAS OF THE MARKET DURING THE REPORTING
PERIOD?

The equity market's advance was broadly based, with the utilities and energy
sectors both advancing more than 30% during the reporting period. Semiconductors
& semiconductor equipment and software & services were the two worst-performing
industry groups, both providing negative returns in U.S. dollars for the 12
months ended October 31, 2004.

WHICH FUND HOLDINGS PERFORMED PARTICULARLY WELL?

The Fund's European utility holdings generated strong results. Italian
gas-transmission company Snam Rete Gas was a case in point. We believe that the
company is well positioned to benefit from the need for gas infrastructure,
which stems from increased demand for gas by both consumers and generators of
electricity. Tesco, a U.K.-based food retailer, also enhanced results, as its
sales continued to grow and earnings surpassed expectations. Porsche is a
designer and manufacturer of sports cars and, more recently, the Cayenne sports
utility vehicle. Porsche has exceeded its sales targets for the Cayenne. In
addition, the sales mix of Porsche's highly profitable sports-car lineup has
shifted to higher-margin models. Looking ahead, we believe the company's sales
growth should slow until a fourth model line is announced. For this reason, we
have recently trimmed the Fund's position to capture profits.

WHAT STOCKS DETRACTED FROM RESULTS?

Weak performers included Rentokil Initial, a European global business-services
company with operations in over 40 countries. The company has been under
pressure as competition has forced profit margins lower. Another holding that
hurt results was Compass Group, an international food-services company that
provides contract and concession catering to more than 90 countries. The company
warned that

Foreign securities may be subject to greater risks than U.S. investments,
including currency fluctuations, less-liquid trading markets, greater price
volatility, political and economic instability, less publicly available
information, and changes in tax or currency laws or monetary policy. These risks
are likely to be greater in emerging markets than in developed markets. The Fund
may invest in derivatives, which may increase the volatility of the Fund's net
asset value and may result in a loss to the Fund.

                                                     www.mainstayfunds.com     7


earnings would fall short of expectations in the current year.

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

NTT DoCoMo, a Japanese wireless telecommunication company, was added to the
Fund's portfolio in December 2003. We have since increased the size of the
position. As the Japanese economy improves, we believe that local companies,
such as NTT DoCoMo, should benefit from increased consumer spending and data
usage. In addition, we believe that negative news related to the competition in
Japan is already reflected in the company's share price and that at its current
valuation, the stock is attractively priced.

Venture, a Singapore-based contract manufacturing-services company, has
benefited from increased demand for printers and handheld computers. We began to
trim the Fund's position when valuations became stretched and the company faced
an increased risk of falling short of earnings expectations. Venture is a
leading company in its sector, and we will continue to look for opportunities to
increase the Fund's exposure to the stock.

HOW IS THE FUND POSITIONED RELATIVE TO THE BENCHMARK?(1)

The Fund's benchmark and the Fund's portfolio are primarily invested in stocks
of developed markets and the Fund tends to have limited exposure to emerging
markets. As always, we remain focused on the fundamental analysis of individual
businesses rather than on the market's perception. At the end of the reporting
period, the portfolio was overweighted in defensive sectors, such as consumer
staples and utilities, with a slightly overweighted position in financials. The
Fund's holdings in consumer staples and utilities provided the biggest positive
contribution to the Fund's absolute performance during the 12-month reporting
period. As of October 31, 2004, underweighted sectors included
telecommunications services and energy. The Fund's holdings in business services
were the prime detractor from the Fund's absolute performance.

WHERE ARE YOU FINDING THE MOST COMPELLING OPPORTUNITIES?

We are finding promising investments in Europe and Asian nations other than
Japan. As a result, the Fund is underweighted in Japan. Recently, however, we
have found businesses in Japan that meet all of our ownership criteria, and we
have reduced the amount by which the Fund is underweighted relative to its
benchmark Index.

WHAT DO YOU ANTICIPATE IN THE COMING MONTHS?

In light of the overall environment, we remain cautiously optimistic. The
portfolio holds companies that we believe are well positioned in their
respective sectors to generate returns above their capital costs. We believe
that the ability to manage capital efficiently is an important characteristic of
good management. As always, we remain alert and are willing to opportunistically
invest in businesses in challenged sectors, such as telecommunications and
media, if we feel they offer compelling values and the potential for a price
correction. By focusing on companies with strong fundamentals and long histories
of stable growth, we feel that we should be able to deliver solid results for
the Fund's shareholders over the long term.

NOTES TO FINANCIAL STATEMENTS

NOTE 1 -- ORGANIZATION AND BUSINESS:

The MainStay Funds (the "Trust") was organized on January 9, 1986 as a
Massachusetts business trust. The Trust is registered under the Investment
Company Act of 1940, as amended (the "1940 Act"), as an open-end management
investment company and comprises twenty-two funds (collectively referred to as
the "Funds"). These financial statements and notes relate only to MainStay
International Equity Fund (the "Fund"), a diversified fund.

The Fund currently offers six classes of shares, Class A shares, Class B shares,
Class C shares, Class I shares, Class R1 shares and Class R2 shares. Class A
shares, whose distribution commenced on January 3, 1995, 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 within one year of purchase
of Class C shares. Class I, Class R1 and Class R2 shares are not subject to
sales charge. Distribution of Class B shares and Class C shares commenced on
September 13, 1994 and September 1, 1998, respectively. Distribution of Class I
shares, Class R1 shares and Class R2 shares commenced on January 2, 2004. The
six classes of shares bear the same voting (except for issues that relate solely
to one class), dividend, liquidation and other rights and conditions except that
Class B shares and Class C shares are subject to higher distribution fee rates
than Class A shares and Class R2 shares under a distribution plan pursuant to
Rule 12b-1 under the 1940 Act. Class I shares and Class R1 shares are not
subject to a distribution or service fee. Class R1 and Class R2 shares are
authorized to pay to New York Life Investment Management LLC, its affiliates, or
independent third-party service providers, as compensation for services rendered
to shareholders of Class R1 or Class R2 shares, a shareholder service fee.

The Fund's investment objective is to provide long-term growth of capital
commensurate with an acceptable level of risk by investing in a portfolio
consisting primarily of non-U.S. equity securities. Current income is a
secondary objective.

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

NOTE 2 -- SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with generally accepted
accounting principles and follows the significant accounting policies described
below.

(A) SECURITIES VALUATION.  Equity securities are valued at the latest quoted
sales prices representative of market values 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 noted bid and asked prices. Prices are taken from the primary market
in which each security trades. 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. Securities for which market quotations are not
readily available are valued by methods deemed by the Board of Trustees to
represent fair value. Reasons for which securities may be valued in this manner
include, but are not limited to, trading for a security has been halted or
suspended, a security has been de-listed from a national exchange, or trading on
a security's primary market is temporarily closed at a time when under normal
conditions it would be open. The Fund did not hold securities at October 31,
2004, that were valued in such manner. Foreign currency forward contracts are
valued at their fair market values determined on the basis of the mean between
the last current bid and asked prices based on dealer or exchange quotations.

Certain events may occur between the time that foreign markets close, on which
securities held by the Fund principally trade, and the time at which the Fund's
NAV is calculated. These events may include, but are not limited to, situations
relating to a single issue in a market sector, significant fluctuations in U.S.
or foreign markets, natural disasters, armed conflicts, governmental actions or
other developments not tied directly to the securities markets. Should the
Manager or Subadvisor conclude that such events may have effected the accuracy
of the last price reported on the local foreign market, the Manager or
Subadvisor may, pursuant to procedures adopted by the Fund, adjust the value of
the local price to reflect the impact on the price of such securities as a
result of such events.

(B) SECURITIES LENDING.  The 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

 18   MainStay International Equity Fund


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.)

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

The use of foreign currency forward contracts involves, to varying degrees,
elements of market risk in excess of the amount recognized in the Statement of
Assets and Liabilities. The contract amount reflects the extent of the Fund's
involvement in these financial instruments. Risks arise from the possible
movements in the foreign exchange rates underlying these instruments. The
unrealized appreciation on forward contracts reflects the Fund's exposure at
period end to credit loss in the event of a counterparty's failure to perform
its obligations.

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

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

(E) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are
recorded on the ex-dividend date. The Fund intends to declare and pay dividends
quarterly and capital gain distributions, if any, annually. 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.

The following table discloses the current period reclassification between
undistributed net investment income and accumulated net realized loss on
investments arising from permanent differences; net assets at October 31, 2004,
are not affected.

<Table>
<Caption>
                              ACCUMULATED
      UNDISTRIBUTED        NET REALIZED LOSS
  NET INVESTMENT INCOME     ON INVESTMENTS
                       

        $328,372              $(328,372)
</Table>

The reclassification for the Fund is primarily due to foreign currency gain
(loss).

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

(G) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred except where direct allocations of expenses can be made. Expenses
(other than expenses incurred under the distribution plans) are allocated to
separate classes of shares based upon their relative net asset value on the date
the expenses are incurred. The expenses borne by the Fund, including those of
related parties to the Fund, are shown in the Statement of Operations.

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

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

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

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

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

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

(I) REDEMPTION FEE.  The Fund imposes a 2.00% redemption fee on redemptions
(including exchanges) of Fund shares made within 60 days of their date of
purchase of Class A, Class B, Class C and Class I shares. The redemption fee is
designed to offset brokerage commissions and other costs associated with
short-term trading and is not assessed on shares acquired through the
reinvestment of dividends or distributions paid by the Fund. The redemption fees
are included in the Statement of Changes in Net Assets' shares redeemed amount
and retained by the Fund.

(J) 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.

NOTE 3 -- FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER AND SUBADVISOR.  New York Life Investment Management LLC ("NYLIM" or
the "Manager"), an indirect wholly-owned subsidiary of New York Life Insurance
Company ("New York Life"), serves as the Fund's manager. The Manager provides
offices, conducts clerical, recordkeeping and bookkeeping services, and keeps
the financial and accounting records required for the Fund. The Manager also
pays the salaries and expenses of all personnel affiliated with the Fund and all
the operational expenses that are not the responsibility of the Fund. MacKay
Shields LLC (the "Subadvisor"), a registered investment advisor and indirect
wholly-owned subsidiary of New York Life, is responsible for the day-to-day
portfolio management of the Fund.

Prior to January 1, 2004, the Fund paid the Manager a monthly fee at an annual
rate of 1.00% of the Fund's average daily net assets up to $1 billion and 0.95%
on assets in excess of $1 billion. As of January 1, 2004, the Trust, on behalf
of the Fund, paid the Manager a monthly fee for services performed and the
facilities furnished at an annual rate of 0.90% of the Fund's average daily net
assets. Effective August 1, 2004, the Trust pays the Manager an annual rate of
0.90% of the Fund's average daily net assets on assets up to $500 million and
0.85% on assets over $500 million. In addition, effective December 1, 2004,
NYLIM has voluntarily agreed to reimburse the expenses of the Fund to the extent
that operating expenses would exceed on an annualized basis 1.95%, 2.70% and
2.70% of the average daily net assets of the Class A, Class B and Class C
shares, respectively and an equivalent reduction in the management fee for Class
I, Class R1 and Class R2 shares. For the year ended October 31, 2004, the
Manager earned from the Fund $1,392,321.

Pursuant to the terms of a Sub-Advisory Agreement between NYLIM and MacKay
Shields, the Manager paid the Subadvisor a monthly fee at an annual rate of
0.60% of the average daily net assets of the Fund. To the extent the Manager has
agreed to reimburse expenses of the Fund, the Subadvisor has voluntarily agreed
to do so proportionately.

Included in the Statement of Operations for the year ended October 31, 2004 is
an amount of approximately $29,551 that was reimbursed by the Subadvisor for a
loss on a security acquired in violation of investment restrictions.

(B) DISTRIBUTION AND SERVICE FEES.  The Trust, on behalf of the Fund, has a
Distribution Agreement with NYLIFE Distributors LLC (the "Distributor"), an
indirect wholly-owned subsidiary of New York Life. The Fund, with respect to
Class A, Class B, Class C and Class R2, has adopted distribution plans (the
"Plans") in accordance with the provisions of Rule 12b-1 under the 1940 Act.
Pursuant to the Class A and Class R2 Plan, the Distributor receives a monthly
fee from the Fund at an annual rate of 0.25% of the average daily net assets of
the Fund's Class A and Class R2 shares, which is an expense of the Class A and
Class R2 shares of the Fund for distribution or service activities as designated
by the Distributor. Pursuant to the Class B and Class C Plans, the Fund pays the
Distributor a monthly fee, which is an expense of the Class B and Class C shares
of the Fund, at the annual rate of 0.75% of the average daily net assets of the
Fund's Class B and Class C shares. The Distribution Plans provide that the Class
B and Class C shares of the Fund 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 Fund. Class I shares and Class R1 shares are not subject to a distribution
or service fee.

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

The Fund has adopted a shareholder services plan with respect to Class R1 and R2
shares. Under the terms of this plan, Class R1 and Class R2 shares are
authorized to pay to NYLIM, its affiliates, or independent third-party
providers, as compensation for services rendered, a shareholder

 20   MainStay International Equity Fund


service fee at the rate of 0.10% of the average daily net assets of the Fund's
Class R1 and R2 shares.

(C) SALES CHARGES.  The Fund was advised by the Distributor that the amount of
sales charges retained on sales of Class A shares was $31,547 for the year ended
October 31, 2004. The Fund was also advised that the Distributor retained
contingent deferred sales charges on redemptions of Class A, Class B and Class C
shares of $7,084, $53,085 and $1,745, respectively, for the year ended October
31, 2004.

(D) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT.  NYLIM
Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's
transfer, dividend disbursing and shareholder servicing agent. NYLIM Service has
entered into an agreement with Boston Financial Data Services ("BFDS") pursuant
to which BFDS will perform certain of the services for which NYLIM Service is
responsible. Transfer agent expenses for the year ended October 31, 2004,
amounted to $665,534.

(E) NON-INTERESTED TRUSTEES FEES.  Non-Interested Trustees are paid an annual
retainer fee of $45,000, $2,000 for each Board meeting, $1,000 for each
Committee meeting and $500 for each Valuation Subcommittee telephonic meeting
attended plus reimbursement for travel and out-of-pocket expenses. The Lead
Non-Interested Trustee is also paid an annual retainer fee of $20,000. The Audit
Committee Chairman receives an additional $2,000 for each meeting of the Audit
Committee attended and the Chairpersons of the Brokerage Committee, Operations
Committee and Performance Committee each receive an additional $1,000 for each
meeting of the Brokerage Committee, Operations Committee and Performance
Committee attended, respectively. In addition, each Non-Interested Trustee is
paid $1,000 for attending meetings of the Non-Interested Trustees held in
advance of or in connection with Board/Committee meetings. The Trust allocates
trustees fees in proportion to the net assets of the respective Funds. Thus the
International Equity Fund only pays a portion of the fees identified above.

(F) CAPITAL.  At October 31, 2004, NYLIFE Distributors held shares of Class A
with a net value of $8,371,258. This represents 11.9% of Class A net assets and
4.5% of the Fund's total net assets at year end.
(G) OTHER.  Fees for the cost of legal services, included in Professional fees
as shown in the Statement of Operations, provided to the Fund by the Office of
the General Counsel of NYLIM amounted to $4,991 for the year ended October 31,
2004.

The Fund pays the Manager a monthly fee for recordkeeping services provided
under the Accounting Agreement at the annual rate of 1/20 of 1% for the first
$20 million of average monthly net assets, 1/30 of 1% of the next $80 million of
average monthly net assets and 1/100 of 1% of any amount in excess of $100
million of average monthly net assets. Fees for recordkeeping services provided
to the Fund by the Manager amounted to $41,937 for the year ended October 31,
2004.

NOTE 4 -- CUSTODIAN:

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

NOTE 5 -- FEDERAL INCOME TAX:

As of October 31, 2004, the components of accumulated gain on a tax basis were
as follows:

<Table>
<Caption>
UNDISTRIBUTED    ACCUMULATED                      TOTAL
   ORDINARY      CAPITAL AND     UNREALIZED    ACCUMULATED

   $440,893       $(980,301)    $21,243,403    $20,703,995
</Table>

The difference between book-basis and tax-basis unrealized appreciation is
primarily due to wash sale deferrals and mark-to-market of foreign currency
forward transactions.

At October 31, 2004, for federal income tax purposes, capital loss carryforwards
of $980,301 were available as shown in the table below, to the extent provided
by the regulations, to offset future realized gains 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.

amount, regardless of usage, to The Bank of New York, which acts as agent to the
syndicate. Such commitment fees are allocated among the funds based upon net
assets and other factors. Interest on any revolving credit loan is charged based

NOTE 10 -- OTHER MATTERS:

NYLIM and mutual funds that NYLIM advises have received requests for information
from various government authorities and regulatory bodies regarding market
timing, late trading, operations, fees, expenses, and other matters. NYLIM and
the funds it advises are cooperating fully in responding to these requests. As
reported in response to those requests for information, NYLIM was previously
party to agreements with certain registered representatives of broker-dealers
relating to the level of trading by clients or customers of those registered
representatives in shares of certain funds of the Trust. NYLIM is continuing to
review what effect, if any, transactions under these agreements may have had on
the funds, and will continue to apprise the Board of Trustees of such
information. NYLIM does not believe at this time that such trading had any
material effect on the funds' financial statements or their shareholders. To
date, substantially all of the costs associated with these and other regulatory
matters have been borne by NYLIM. Except as described below, neither NYLIM nor
the funds advised by it have any reason to believe that they have been targeted
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.
Discussions have been held with the SEC concerning a possible resolution of this
matter. These discussions are continuing, but there can be no assurance at this
time as to the outcome of these efforts.

NOTE 11 -- CHANGE IN INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM (UNAUDITED):

On March 8, 2004, KPMG LLP ("KPMG") was selected as the Trust's independent
auditor for the 2004 fiscal year. The selection of KPMG was recommended by the
Trust's Audit Committee, comprised of all Non-Interested Trustees, and was
approved by the Trust's Board of Trustees.

The predecessor independent auditor's reports on the Trust's financial
statements for the period ended October 31, 2003 and year ended December 31,
2002 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 periods, through the date of engagement of KPMG, there were
no disagreements between 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 periods.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Trustees and Shareholders of
The MainStay Funds:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of the MainStay International Equity Fund (the
"Fund"), one of the funds constituting The MainStay Funds, as of October 31,
2004, and the related statement of operations, statement of changes in net
assets and the financial highlights for the year or period then ended. These
financial statements and financial highlights are the responsibility of the
Fund's management. Our responsibility is to express an opinion on these
financial statements and financial highlights based on our audit. The statement
of changes in net assets for the period ended October 31, 2003 and the year
ended December 31, 2002, and the financial highlights for the periods presented
through October 31, 2003, were audited by other auditors, whose report dated
December 18, 2003 expressed an unqualified opinion thereon.

We conducted our audit in accordance with the Standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
also includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2004 by correspondence with the custodian and
brokers. As to securities purchased or sold but not yet received or delivered,
we performed other appropriate auditing procedures. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
MainStay International Equity Fund of The MainStay Funds as of October 31, 2004,
the results of its operations, the changes in its net assets and its financial
highlights for the year or period then ended, in conformity with U.S. generally
accepted accounting principles.

MESSAGE FROM
THE PRESIDENT

During the 12 months ended October 31, 2004, the U.S. stock market advanced, but
its pace and direction were by no means steady. Small- and mid-capitalization
stocks tended to outperform large-cap issues, and value stocks generally
outperformed growth stocks.

Economic activity, as measured by gross domestic product, increased from 4.2% in
the fourth quarter of 2003 to 4.5% in the first quarter of 2004. The pace of
economic growth slowed to 3.3% in the second quar-ter of 2004, and according to
preliminary estimates
from the Bureau of Economic Analysis, gross domes-
tic product grew at a seasonally adjusted annual rate
of 3.9% in the third quarter of 2004.

Interest rates began the reporting period at a low 1.00%. In June 2004, the
Federal Open Market Committee responded to expanding output and improved labor
markets by raising the targeted federal funds rate by 25 basis points. Similar
moves in August and September brought the targeted federal funds rate to 1.75%.
In its September 2004 release, the Federal Open Market Committee affirmed its
belief that monetary policy remained accommodative.

Despite rising interest rates, bond markets generally advanced. High-yield bonds
and emerging-market debt were particularly strong. The U.S. dollar declined
relative to most other currencies, which helped U.S. exporters.

In pursuing its investment objective, each MainStay Fund consistently seeks to
apply a well-defined investment process in all market environments. We believe
that a consistent, disciplined investment approach can help investors make more
prudent and practical decisions regarding their investments.

In the report that follows, you'll find additional information about the market
forces, investment decisions, and individual securities that affected your
MainStay Fund during the 12 months ended October 31, 2004. We thank you for
investing with us, and we look forward to many years of continued service in
your behalf.
Sincerely,
/s/ GARY E. WENDLANDT
Gary E. Wendlandt

President

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

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

WHAT MAJOR FACTORS AND RISKS INFLUENCED THE STOCK MARKET DURING THE 12 MONTHS
ENDED OCTOBER 31, 2004?

Among the most significant factors influencing the equity markets during the
reporting period were Federal Reserve interest-rate hikes, sharply higher oil
prices, the war in Iraq, and the uncertainty surrounding the presidential
election. Despite these concerns, the stock market managed to register a healthy
gain. Much of the market's advance occurred toward the end of the reporting
period, when investors began to refocus on those market fundamentals, such as
earnings growth, that appeared to be favorable.

CAN YOU BRIEFLY DESCRIBE THE FUND'S INVESTMENT APPROACH?

The Fund invests primarily in common stocks and securities related to U.S.
common stocks of companies with market capitalizations similar to those market
capitalization of companies in the S&P MidCap 400(R) Index.(1) The Fund seeks to
participate primarily in expanding markets of technology, health care,
communications, and other high-growth industries. We also seek stocks with
above-average growth in earnings. We select investments according to the
economic environment and the attractiveness of particular markets and the
financial condition and competitiveness of individual companies. In implementing
this strategy, we use a flexible approach and may invest in various types of
companies and securities. We look for securities that we believe may be poised
for a rise in price or an acceleration in earnings growth--possibly because of
special factors, such as changes in management, products, consumer demand, or
the economy. We may sell a stock if its earnings growth rate decelerates, if it
appears overvalued in relation to its growth rate or peer group, or if the stock
no longer appears likely to help the Fund meet its investment objective.

WHAT FACTORS HAD THE GREATEST IMPACT ON THE FUND'S RELATIVE PERFORMANCE?

The Fund's strong performance relative to its peers during the reporting period
resulted primarily from individual security selection in the health care,
consumer discretionary, and information technology sectors. The Fund's
underweighted position in the energy sector, however, detracted from
performance. Although the Fund's energy stocks advanced in concert with the
rising price of oil, the portfolio's underweighted position in the sector held
back performance.

WHAT DECISIONS GUIDED THE FUND'S PERFORMANCE DURING THE REPORTING PERIOD?

We increased the Fund's exposure to the consumer discretionary sector, which had
a positive impact on the Fund's performance during the reporting period. Our
move to reduce the Fund's weighting in the information technology sector also
proved beneficial. While our decision to increase the Fund's exposure in the
high-performing energy sector had a positive impact, the Fund remained
underweighted in the sector, which hurt relative performance.

WHICH STOCKS WERE THE STRONGEST POSITIVE CONTRIBUTORS TO THE FUND'S PERFORMANCE?

For the 12-months ended October 31, 2004, the holdings that made the greatest
positive contribution to the Fund's performance were Autodesk, Oxford Health
Plans and Harman International Industries. Autodesk, one of the world's leading
design-software and digital-content companies, recently received international
recognition for its flagship AutoCAD software. The stock also rose on news of a
75% gain in third-quarter earnings. Oxford Health Plans was acquired by
Minnesota-based UnitedHealth Group in April at a substantial premium. The stock
benefited strongly from the acquisition. Harman International, a manufacturer of
high-quality, high-fidelity audio and electronic products, is benefiting from
its solid long-term contracts with several major automakers. The company has
profited from its growing sales in the high-margin luxury auto category. New
Century Financial, a mortgage company, and Cytyc, a developer of medical
diagnostic products for cervical-cancer screening, also contributed strongly to
the Fund's performance.

WHICH STOCKS WERE THE LARGEST DETRACTORS FROM PERFORMANCE?

During the 12-month reporting period, the largest detractors from the Fund's
performance were Emulex, QLogic, New York Community Bancorp, JetBlue Airways,
and SPX. Emulex and Qlogic, which provide interface connections between computer
systems and their attached data-storage peripherals, announced disappointing
results for the fourth quarter of 2003. A majority of the companies' revenue
shortfall was related to a decline in expected orders

Mid-capitalization companies are generally less established and their stocks may
be more volatile and less liquid than the securities of larger companies.

from original-equipment manufacturers for host bus adapters (HBA's) at the end
of the quarter. We sold Emulex on the news but continue to own Qlogic. Since
then QLogic managed to avoid further losses by taking some market share from
Emulex. New York Community Bancorp's shares declined on the news of a
significant drop in earnings for 2004. After the company's merger with Roslyn
Bancorp, the big sell-off in bonds earlier in the year caught highly leveraged
New York Community Bancorp off guard. The company's thrift was forced to unload
some $5 billion of interest-rate sensitive securities, and incur steep losses.
We sold the shares on the news.

The rising price of oil has increased operating costs throughout the airline
industry, which was already suffering from thin profit margins. As the outlook
darkened, we sold the Fund's position in JetBlue.

SPX designs, manufactures, and markets equipment for networking, broadcast,
power, and fire-detection applications. The company's share price declined when
third-quarter 2004 earnings per share came in below expectations. The company
reported that various costs and expenses have had an impact on margins. Although
the Fund owned the stock at the end of the reporting period, we have since sold
the Fund's position.

WERE THERE ANY SIGNIFICANT PURCHASES DURING THE REPORTING PERIOD?

Yes. With energy prices at high levels, we purchased Chesapeake Energy,
National-Oilwell, and Newfield Exploration for the Fund. In the materials
sector, we purchased shares of coal company Peabody Energy. In the industrials
sector, we added construction and surface-mining equipment manufacturer Terex.
We added to the Fund's consumer discretionary holdings with the purchase of Penn
National Gaming, as well as The St. Joe Company. In health care, we added Sierra
Health Services.

WHICH STOCKS DID THE FUND SELL DURING THE REPORTING PERIOD?

In light of difficulties throughout the airline industry, we decided to sell the
Fund's position in SkyWest. In the consumer discretionary sector, we sold the
Fund's shares of mass merchandiser Fred's, which showed poor performance
throughout the reporting period. We also sold pharmaceutical-products
distributor AmerisourceBergen. In the financials sector, we sold New York
Community Bancorp, and in information technology, we sold Siebel Systems, which
faltered early in 2004 and showed poor performance through the remainder of the
reporting period.

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

The Fund increased its exposure to the consumer discretionary sector from 27.5%
at the end of October 2003 to 29.8% at the end of October 2004. Over the same
period, we increased the Fund's weighting in the energy sector from 0.0% to
4.2%. We increased the Fund's financials sector weighting from 9.8% of net
assets at the beginning of the reporting period to 12.7% at the end. Over the
same period, the Fund's allocation to the materials sector grew from 0.1% to
6.4%.

From the beginning of the reporting period to the end of October 2004, the Fund
decreased its weighting in the industrials sector from 15.3% to 10.7% and
reduced its weighting in the information technology sector from 25.2% to 13.5%.

HOW DO THE FUND'S WEIGHTINGS COMPARE WITH THOSE OF THE RUSSELL 2500(R) GROWTH
INDEX?

As of October 31, 2004, the Fund was overweighted relative to the Russell
2500(R) Growth Index(2) in the consumer discretionary, financials, health care,
industrials, and materials sectors. At the same time, the Fund was underweighted
in the consumer staples, energy, industrials, and information technology
sectors. At the end of the reporting period, the Fund had no holdings in the
telecommunications services or utilities sectors.

WHAT IS YOUR OUTLOOK FOR THE FUND?

With the uncertainty of the presidential election now behind us, investors can
now focus their attention on market fundamentals. Although high energy prices
and terrorism concerns remain risk factors, we believe that the combination of
moderate economic growth and relatively low interest rates may help support
decent stock-price action going forward.

NOTES TO FINANCIAL STATEMENTS

NOTE 1 -- ORGANIZATION AND BUSINESS:

The MainStay Funds (the "Trust") was organized on January 9, 1986 as a
Massachusetts business trust. The Trust is registered under the Investment
Company Act of 1940, as amended (the "1940 Act"), as an open-end management
investment company and comprises twenty-two funds (collectively referred to as
the "Funds"). These financial statements and notes relate only to MainStay Mid
Cap Growth Fund (the "Fund"), a diversified fund.

The Fund currently offers three classes of shares. Distribution of Class A
shares, Class B shares and Class C shares commenced on January 2, 2001. 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 within one
year of purchase of Class C shares. Class A shares, Class B shares and Class C
shares bear the same voting (except for issues that relate solely to one class),
dividend, liquidation and other rights and conditions except that the Class B
shares and Class C shares are subject to higher distribution fee rates. Each
class of shares bears distribution and/or service fee payments under a
distribution plan pursuant to Rule 12b-1 under the 1940 Act.

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

NOTE 2 -- SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with generally accepted
accounting principles and follows the significant accounting policies described
below.

(A) SECURITIES VALUATION.  Equity securities are valued at the latest quoted
sales prices as of the close of 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. 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.
Securities for which market quotations are not readily available are valued by
methods deemed by the Board of Trustees to represent fair value. Reasons for
which securities may be valued in this manner include, but are not limited to,
trading for a security has been halted or suspended, a security has been
de-listed from a national exchange, or trading on a security's primary market is
temporarily closed at a time when under normal conditions it would be open. The
Fund did not hold securities at October 31, 2004, that were valued in such
manner.

(B) SECURITIES LENDING.  The Fund may lend its securities to broker-dealers and
financial institutions. The loans are collateralized by cash or securities at
least equal at all times to the market value of the securities loaned. The Fund
may bear the risk of delay in recovery of, or loss of rights in, the securities
loaned should the borrower of the securities experience financial difficulty.
The Fund receives compensation for lending its securities in the form of fees or
it retains a portion of interest on the investment of any cash received as
collateral. The Fund also continues to receive interest and dividends on the
securities loaned and any gain or loss in the market price of the securities
loaned that may occur during the term of the loan will be for the account of the
Fund. (See Note 7.)

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

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

(D) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are
recorded on the ex-dividend date. The Fund intends to declare and pay any
dividends quarterly and capital gain distributions, if any, annually. 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.

The following table discloses the current period reclassification between
accumulated net investment loss and

 18   MainStay Mid Cap Growth Fund


additional paid-in capital arising from permanent differences; net assets at
October 31, 2004, are not affected.

<Table>
<Caption>
 ACCUMULATED
NET INVESTMENT     ADDITIONAL
     LOSS        PAID-IN CAPITAL
              
  $1,012,631       $(1,012,631)
</Table>

The reclassification for the Fund is due to the fact that net operating losses
cannot be carried forward for federal income tax purposes.

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

(F) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred except where direct allocations of expenses can be made. Expenses
(other than expenses incurred under the distributions plans) are allocated to
separate classes of shares based upon their relative net asset value on the date
the expenses are incurred. The expenses borne by the Fund, including those of
related parties to the Fund, are shown in the Statement of Operations.

(G) USE OF ESTIMATES.  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.

NOTE 3 -- FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER AND SUBADVISOR.  New York Life Investment Management LLC ("NYLIM" or
the "Manager"), an indirect wholly-owned subsidiary of New York Life, serves as
the Fund's manager. The Manager provides offices, conducts clerical,
recordkeeping and bookkeeping services, and keeps the financial and accounting
records required for the Fund. The Manager also pays the salaries and expenses
of all personnel affiliated with the Fund and all the operational expenses that
are not the responsibility of the Fund. MacKay Shields LLC (the "Subadvisor"), a
registered investment advisor and indirect wholly-owned subsidiary of New York
Life, is responsible for the day-to-day portfolio management of the Fund.

Through July 31, 2004, the Trust, on behalf of the Fund, paid the Manager a
monthly fee for services performed and the facilities furnished at an annual
rate of 0.75% of the Fund's average daily net assets. Effective August 1, 2004,
the Trust pays the Manager an annual rate of 0.75% of the Fund's average daily
net assets on assets up to $500 million and 0.70% on assets over $500 million.
The Manager has voluntarily agreed to reimburse the expenses of the Fund to the
extent that operating expenses would exceed on an annualized basis 1.50%, 2.25%
and 2.25% of the average daily net assets of the Class A, Class B and Class C
shares, respectively. For the year ended October 31, 2004, the Manager earned
from the Fund $573,781 and reimbursed the Fund $147,001.

Pursuant to the terms of a Sub-Advisory Agreement between NYLIM and the
Subadvisor, the Manager pays the Subadvisor a monthly fee at an annual rate of
0.375% of the average daily net assets of the Fund. To the extent the Manager
has agreed to reimburse expenses of the Fund, the Subadvisor has voluntarily
agreed to do so proportionately.

(B) DISTRIBUTION AND SERVICE FEES.  The Trust, on behalf of the Fund, has a
Distribution Agreement with NYLIFE Distributors LLC (Distributor). The Fund,
with respect to each class of shares, has adopted distribution plans (the
"Plans") in accordance with the provisions of Rule 12b-1 under the 1940 Act.
Pursuant to the Class A Plan, the Distributor receives a monthly fee from the
Fund at an annual rate of 0.25% of the average daily net assets of the Fund's
Class A shares, which is an expense of the Class A shares of the Fund for
distribution or service activities as designated by the Distributor. Pursuant to
the Class B and Class C Plans, the Fund pays the Distributor a monthly fee,
which is an expense of the Class B and Class C shares of the Fund, at the annual
rate of 0.75% of the average daily net assets of the Fund's Class B and Class C
shares. The Distribution Plans provide that the Class B and Class C shares of
the Fund 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 Fund.

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

(C) SALES CHARGES.  The Fund was advised by the Distributor that the amount of
sales charges retained on sales of Class A shares was $26,560 for the year ended
October 31, 2004. The Fund was also advised that the Distributor retained
contingent deferred sales charges on redemptions of Class A, Class B and Class C
shares of $5, $36,031 and $1,750, respectively, for the year ended October 31,
2004.

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

(D) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT.  NYLIM
Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's
transfer, dividend disbursing and shareholder servicing agent. NYLIM Service has
entered into an agreement with Boston Financial Data Services ("BFDS") pursuant
to which BFDS will perform certain of the services for which NYLIM Service is
responsible. Transfer agent expenses for the year ended October 31, 2004,
amounted to $332,891.

(E) NON-INTERESTED TRUSTEES FEES.  Non-Interested Trustees are paid an annual
retainer fee of $45,000, $2,000 for each Board meeting, $1,000 for each
Committee meeting and $500 for each Valuation Subcommittee telephonic meeting
attended plus reimbursement for travel and out-of-pocket expenses. The Lead
Non-Interested Trustee is also paid an annual retainer fee of $20,000. The Audit
Committee Chairman receives an additional $2,000 for each meeting of the Audit
Committee attended and the Chairpersons of the Brokerage Committee, Operations
Committee and Performance Committee each receive an additional $1,000 for each
meeting of the Brokerage Committee, Operations Committee and Performance
Committee attended, respectively. In addition, each Non-Interested Trustee is
paid $1,000 for attending meetings of the Non-Interested Trustees held in
advance of or in connection with Board/Committee meetings. The Trust allocates
trustees fees in proportion to the net assets of the respective Funds. Thus the
Mid Cap Growth Fund only pays a portion of the fees identified above.

(F) CAPITAL.  At October 31, 2004, New York Life held shares of Class A with a
value of $22,725,000 which represents 49.2% of the Class A net assets and 26.6%
of the Fund's total net assets at year end.

(G) OTHER.  Fees for the cost of legal services, included in Professional fees
as shown on the Statement of Operations, provided to the Fund by the Office of
the General Counsel of NYLIM amounted to $2,446 for the year ended October 31,
2004.

The Fund pays the Manager a monthly fee for recordkeeping services provided
under the Accounting Agreement at the annual rate, 1/20 of 1% for the first $20
million of average monthly net assets, 1/30 of 1% of the next $80 million of
average monthly net assets and 1/100 of 1% of any amount in excess of $100
million of average monthly net assets. Fees for recordkeeping services provided
to the Fund by the Manager amounted to $28,835 for the year ended October 31,
2004.

NOTE 4 -- CUSTODIAN:

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

NOTE 5 -- FEDERAL INCOME TAX:

As of October 31, 2004, the components of accumulated gain on a tax basis were
as follows:

<Table>

                                          TOTAL

   $(10,441,183)        $17,221,042    $6,779,859
</Table>

The difference between book-basis and tax-basis unrealized appreciation is due
to wash sale deferrals.

At October 31, 2004, for federal income tax purposes, capital loss carryforwards
of $10,441,183 were available as shown in the table below, to the extent
provided by the regulations, to offset future realized gains 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.

accordance with Fund's securities lending procedures. Pursuant to Rule 2a-7,
securities purchased with collateral received are valued at amortized cost.

NOTE 8 -- LINE OF CREDIT:

The Fund and certain affiliated funds maintain a line of credit of $160,000,000
with a syndicate of banks in order to secure a source of funds for temporary
purposes to meet unanticipated or excessive shareholder redemption requests. The
funds pay a commitment fee, at an annual rate of .075% of the average commitment
amount, regardless of usage, to The Bank of New York, which acts as agent to the
syndicate. Such commitment fees are allocated among the funds based upon net
assets and other factors.

NOTE 10 -- OTHER MATTERS:

NYLIM and mutual funds that NYLIM advises have received requests for information
from various government authorities and regulatory bodies regarding market
timing, late trading, operations, fees, expenses, and other matters. NYLIM and
the funds it advises are cooperating fully in responding to these requests. As
reported in response to those requests for information, NYLIM was previously
party to agreements with certain registered representatives of broker-dealers
relating to the level of trading by clients or customers of those registered
representatives in shares of certain funds of the Trust. NYLIM is continuing to
review what effect, if any, transactions under these agreements may have had on
the funds, and will continue to apprise the Board of Trustees of such
information. NYLIM does not believe at this time that such trading had any
material effect on the funds' financial statements or their shareholders. To
date, substantially all of the costs associated with these and other regulatory
matters have been borne by NYLIM. Except as described below, neither NYLIM nor
the funds advised by it have any reason to believe that they have been targeted
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.
Discussions have been held with the SEC concerning a possible resolution of this
matter. These discussions are continuing, but there can be no assurance at this
time as to the outcome of these efforts.

NOTE 11 -- CHANGE IN INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM (UNAUDITED):

On March 8, 2004, KPMG LLP ("KPMG") was selected as the Trust's independent
auditor for the 2004 fiscal year. The selection of KPMG was recommended by the
Trust's Audit Committee, comprised of all Non-Interested Trustees, and was
approved by the Trust's Board of Trustees.

The predecessor independent auditor's report on the Trust's financial statements
for the period ended October 31, 2003 and year ended December 31, 2002 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 periods, and through the date of engagement of KPMG, there were no
disagreements between 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 periods.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Trustees and Shareholders of
The MainStay Funds:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of the MainStay Mid Cap Growth Fund (the "Fund"),
one of the funds constituting The MainStay Funds, as of October 31, 2004, and
the related statement of operations, statement of changes in net assets and the
financial highlights for the year then ended. These financial statements and
financial highlights are the responsibility of the Fund's management. Our
responsibility is to express an opinion on these financial statements and
financial highlights based on our audit. The statement of changes in net assets
for the period ended October 31, 2003 and the year ended December 31, 2002, and
the financial highlights for the periods presented through October 31, 2003,
were audited by other auditors, whose report dated December 18, 2003 expressed
an unqualified opinion thereon.

We conducted our audit in accordance with the Standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
also includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2004 by correspondence with the custodian and
brokers. As to securities purchased or sold but not yet received or delivered,
we performed other appropriate auditing procedures. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
MainStay Mid Cap Growth Fund of The MainStay Funds as of October 31, 2004, the
results of its operations, the changes in its net assets and its financial
highlights for the year then ended, in conformity with U.S. generally accepted
accounting principles.

 2   MainStay Money Market Fund


MESSAGE FROM
THE PRESIDENT

During the 12 months ended October 31, 2004, the U.S. stock market advanced, but
its pace and direction were by no means steady. Small- and mid-capitalization
stocks tended to outperform large-cap issues, and value stocks generally
outperformed growth stocks.

Economic activity, as measured by gross domestic product, increased from 4.2% in
the fourth quarter of 2003 to 4.5% in the first quarter of 2004. The pace of
economic growth slowed to 3.3% in the second quarter of 2004, and according to
preliminary estimates from the Bureau of Economic Analysis, gross domestic
product grew at a seasonally adjusted annual rate of 3.9% in the third quarter
of 2004.

Interest rates began the reporting period at a low 1.00%. In June 2004, the
Federal Open Market Committee responded to expanding output and improved labor
markets by raising the targeted federal funds rate by 25 basis points. Similar
moves in August and September brought the targeted federal funds rate to 1.75%.
In its September 2004 release, the Federal Open Market Committee affirmed its
belief that monetary policy remained accommodative.

Despite rising interest rates, bond markets generally advanced. High-yield bonds
and emerging-market debt were particularly strong. The U.S. dollar declined
relative to most other currencies, which helped U.S. exporters.

In pursuing its investment objective, each MainStay Fund consistently seeks to
apply a well-defined investment process in all market environments. We believe
that a consistent, disciplined investment approach can help investors make more
prudent and practical decisions regarding their investments.

In the report that follows, you'll find additional information about the market
forces, investment decisions, and individual securities that affected your
MainStay Fund during the 12 months ended October 31, 2004. We thank you for
investing with us, and we look forward to many years of continued service in
your behalf.

Sincerely,
/s/ GARY E. WENDLANDT
Gary E. Wendlandt

President

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. Class A, B, and C shares are sold with no initial sales charge or
contingent deferred sales charge (CDSC) and have no annual 12b-1 fees.
Performance figures reflect certain fee waivers and/or expense limitations,
without which total returns may have been lower. The fee waivers and/or expense
limitations are voluntary and may be discontinued at any time. From inception
(5/1/86) through 12/31/94 (for Class A, first offered 1/3/95) and 8/31/98 (for
Class C, first offered 9/1/98), performance of Class A and Class C shares
includes the historical performance of Class B shares.
1. 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 10/31/04, MainStay Money Market Fund had an effective 7-day yield of
   1.10% and a 7-day current yield of 1.10% for Class A, B, and C shares. These
   yields reflect certain expense limitations. Had these expense limitations not
   been in effect, the effective 7-day yield and the current 7-day yield would
   have been 0.69%. 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 data 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 Claude Athaide, Ph.D., CFA, and
Christopher Harms of MacKay Shields LLC

CAN YOU BRIEFLY DESCRIBE THE FUND'S INVESTMENT APPROACH?
The Fund invests in high-quality, short-term securities that are denominated in
U.S. dollars and mature in 13 months or less. The Fund's portfolio may include
obligations issued or guaranteed by the U.S. government or any of its agencies
or instrumentalities. The Fund may also invest in bank and bank holding company
obligations, such as CDs and bankers' acceptances. The Fund may own commercial
paper, unsecured loans to corporations, and corporate debt securities. We may
sell a security if changes in the economy, the financial situation of the
issuer, the condition and outlook of the issuer's industry, or other factors
lead us to believe that the security will not contribute to meeting the Fund's
investment objective.
WHAT WAS THE ECONOMIC ENVIRONMENT DURING THE REPORTING PERIOD?
The Commerce Department estimated that the U.S. economy grew at a 3.9%
annualized rate during the four quarters ended September 30, 2004. Personal
consumption grew at a 3.5% pace during this period, while business fixed
investment grew at a 9.8% rate. Following the recession in 2001, the first two
years of the economic recovery were characterized by lackluster employment
gains. During March, April, and May of 2004, however, U.S. payrolls expanded
strongly, adding a total of nearly 900,000 jobs. In the next few months,
employment growth moderated. The most recent employment report showed that
337,000 new jobs were created in October 2004, and figures for jobs created
during August and September were revised upward. In all, payrolls have increased
by more than two million during the 12 months ended October 31, 2004.
HOW DID THE EXPANDING ECONOMY AFFECT INTEREST RATES?
During the spring of 2004, markets were surprised by higher-than-expected
inflation. This, combined with an improving employment picture, caused interest
rates to move sharply higher. From late March through June 2004, two-year
Treasury-note yields rose from 1.46% to 2.93%. During the summer, yields
declined as job growth slowed and inflation concerns were reduced. On October
31, 2004, two-year Treasury notes yielded 2.56%. During the 12-month reporting
period, yields on the three-month Treasury bill rose from 0.95% to 1.9% while
three-month LIBOR(1) increased from 1.17% to 2.17%.
WHAT WAS THE FEDERAL RESERVE'S RESPONSE TO THE ECONOMY?
The Federal Open Market Committee raised the targeted federal funds rate in
June, August, and September of 2004--by 25 basis points each time. (A basis
point is 1/100th of one percent.) These three rates hikes brought the targeted
federal funds rate from 1.00% to 1.75%.
HOW DID THE FUND INVEST DURING THE REPORTING PERIOD?
The duration of the Fund was longer than that of the average money-market fund
during the Fund's fiscal year. In the second half of the reporting period, this
stance had a negative impact on performance as securities in the portfolio were
reinvested into higher-yielding instruments at a slower rate.
The Fund's portfolio contained securities issued by the U.S. Treasury and
government-sponsored agencies. The Fund also held securities issued by finance,
insurance, brokerage, and industrial companies, as well as banks and bank
holding companies. These were first-tier securities, or generally those money
market instruments in the highest-rated category.
WHAT DO YOU ANTICIPATE GOING FORWARD?
Consumer spending grew at 4.6% in the third quarter of 2004, while the personal
savings rate declined to 0.4%. We do not believe that these trends are
sustainable. Earlier in the year, consumers received substantial stimulus from
tax cuts and mortgage refinancings but we are unlikely to see additional support
from these sources. Strong employment growth will be necessary for consumer
spending to remain at these levels without further deterioration in the savings
balance. In our opinion, personal spending is unlikely to grow faster than wages
during the next few quarters.
Activity in the futures market suggests an 80% probability that after the
February 2005 meeting of the Federal Open Market Committee, the targeted federal
funds rate will reach 2.5%. Since we believe

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.

that the FOMC will be somewhat less aggressive, we will continue to purchase
securities maturing in February as long as they appear to offer attractive
opportunities.

NOTES TO FINANCIAL STATEMENTS

NOTE 1 -- ORGANIZATION AND BUSINESS:

The MainStay Funds (the "Trust") was organized on January 9, 1986 as a
Massachusetts business trust. The Trust is registered under the Investment
Company Act of 1940, as amended (the "1940 Act"), as an open-end management
investment company and comprises twenty-two funds (collectively referred to as
the "Funds"). These financial statements and notes relate only to MainStay Money
Market Fund (the "Fund"), a diversified fund.

The Fund currently offers three classes of shares. Class A shares, Class B
shares and Class C shares whose distribution commenced on January 3, 1995, May
1, 1986 and September 1, 1998, respectively. The shares bear the same voting
(except for issues that relate solely to one class), dividend, liquidation and
other rights and conditions.

The Fund's investment objective is to seek as high a level of current income as
is considered consistent with the preservation of capital and liquidity.

The Fund's principal investments include derivatives such as variable rate
master demand notes, "floating-rate notes" and mortgage-related and asset-backed
securities. If expectations about change in interest rates, or assessments of an
issuer's creditworthiness or market conditions are wrong, the use of derivatives
or other investments could result in a loss.

The Fund also invests in foreign securities which carry certain risks 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 and restrictions.

The ability of issuers of debt securities held by the Fund to meet their
obligations may be affected by economic and political developments in a specific
country, industry or region.

NOTE 2 -- SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with generally accepted
accounting principles and follows the significant accounting policies described
below.

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

(B) SECURITIES VALUATION.  Pursuant to Rule 2a-7 securities are valued at their
amortized cost. The amortized cost method involves valuing a security at its
cost on the date of purchase and thereafter assuming a constant amortization to
maturity of the difference between such cost and the value on maturity date.

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

(D) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are
recorded on the ex-dividend date. Dividends are declared daily and paid monthly
and capital gain distributions, if any, annually. Income dividends and capital
gain distributions are determined in accordance with federal income tax
regulations, which may differ from generally accepted accounting principles.

The following table discloses the current year reclassifications between
accumulated net realized gain and undistributed net investment income. Net
assets at October 31, 2004 were not affected.

            $(9,721)             $9,721
- ---------------------------------------
</Table>

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

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

(F) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred except where direct allocations of expenses can be made. Expenses are
allocated to separate classes of shares based upon their relative net asset
value on the date the expenses are incurred. The expenses borne by the Fund,
including those of related parties to the Fund, are shown in the Statement of
Operations.

(G) USE OF ESTIMATES.  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.

NOTE 3 -- FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER AND SUBADVISOR.  New York Life Investment Management LLC ("NYLIM" or
the "Manager"), an indirect wholly-owned subsidiary of New York Life Insurance
Company ("New York Life"), serves as the Fund's manager. The Manager provides
offices, conducts clerical, recordkeeping and bookkeeping services, and keeps
the financial and accounting records required for the Fund. The Manager also
pays the salaries and expenses of all personnel affiliated with the Fund and all
the operational expenses that are not the responsibility of the Fund. MacKay
Shields LLC (the "Subadvisor"), a registered investment adviser and indirect
wholly-owned subsidiary of New York Life, is responsible for the day-to-day
portfolio management of the Fund.

The Trust, on behalf of the Fund, paid the Manager a monthly fee for services
performed and the facilities furnished at an annual rate of the Fund's average
daily net assets of 0.50% up to $300 million, 0.45% on assets from $300 million
to $700 million, 0.40% on assets from $700 million to $1 billion and 0.35% on
assets in excess of $1 billion. The Manager has voluntarily agreed to assume the
expenses of the Fund to the extent that such expenses would exceed on an annual
basis 0.70% of the average daily net assets of the Fund. For the year ended
October 31, 2004 the Manager earned from the Fund $2,670,028 and reimbursed the
Fund $1,786,551.

Pursuant to the terms of a Sub-Advisory Agreement between NYLIM and MacKay
Shields, the Manager paid the Subadvisor a monthly fee at an annual rate of the
Fund's average daily net assets of 0.25% up to $300 million, 0.225% on assets
from $300 million to $700 million, 0.20% on assets from $700 million to $1
billion and 0.175% on assets in excess of $1 billion. To the extent the Manager
has agreed to reimburse expenses of the Fund, the Subadvisor has voluntarily
agreed to do so proportionately.

(B) CONTINGENT DEFERRED SALES CHARGE.  Although the Fund does not assess a
contingent deferred sales charge upon redemption of Class B or Class C shares of
the Fund, the applicable contingent deferred sales charge will be assessed when
shares are redeemed from the Fund if the shareholder previously exchanged his or
her investment into the Fund from another Fund in the Trust. The Fund was
advised that NYLIFE Distributors LLC (the "Distributor"), an indirect wholly
owned subsidiary of New York Life, received from shareholders the proceeds from
contingent deferred sales charges for the year ended October 31, 2004, in the
amount of $783,723.

(C) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT.  NYLIM
Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's
transfer, dividend disbursing and shareholder servicing agent. NYLIM Service has
entered into an agreement with Boston Financial Data Services ("BFDS") pursuant
to which BFDS will perform certain of the services for which NYLIM Service is
responsible. Transfer agent expenses for the year ended October 31, 2004
amounted to $2,528,884.

(D) NON-INTERESTED TRUSTEES FEES.  Non-Interested Trustees are paid an annual
retainer fee of $45,000, $2,000 for each Board meeting, $1,000 for each
Committee meeting and $500 for each Valuation Subcommittee telephonic meeting
attended plus reimbursement for travel and out-of-pocket expenses. The Lead
Non-Interested Trustee is also paid an annual retainer fee of $20,000. The Audit
Committee Chairman receives an additional $2,000 for each meeting of the Audit
Committee attended and the Chairpersons of the Brokerage Committee, Operations
Committee and Performance Committee each receive an additional $1,000 for each
meeting of the Brokerage Committee, Operations Committee and Performance
Committee attended, respectively. In addition, each Non-Interested Trustee is
paid $1,000 for attending meetings of the Non-Interested Trustees held in
advance of or in connection with Board/Committee meetings. The Trust allocates
trustees fees in proportion to the net assets of the respective Funds. Thus the
Money Market Fund only pays a portion of the fees identified above.

(E) OTHER.  Fees for the cost of legal services, included in Professional fees
as shown on the Statement of Operations, provided to the Fund by the Office of
the General Counsel of NYLIM amounted to $16,837 for the year ended October 31,
2004.

The Fund pays the Manager a monthly fee for recordkeeping services provided
under the Accounting Agreement at the annual rate of 1/20 of 1% for the first
$20 million of average monthly net assets, 1/30 of 1% of the next $80 million of
average monthly net assets and 1/100 of 1% of any amount in excess of $100
million of average monthly net assets. Fees for recordkeeping services provided
to the Fund by the Manager amounted to $82,668 for the year ended October 31,
2004.

NOTE 4 -- CUSTODIAN:

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

NOTE 7 -- OTHER MATTERS:

NYLIM and mutual funds that NYLIM advises have received requests for information
from various government authorities and regulatory bodies regarding market
timing, late trading, operations, fees, expenses, and other matters. NYLIM and
the funds it advises are cooperating fully in responding to these requests. As
reported in response to those requests for information, NYLIM was previously
party to agreements with certain registered representatives of broker-dealers
relating to the level of trading by clients or customers of those registered
representatives in shares of certain funds of the Trust. NYLIM is continuing to
review what effect, if any, transactions under these agreements may have had on
the funds, and will continue to apprise the Board of Trustees of such
information. NYLIM does not believe at this time that such trading had any
material effect on the funds' financial statements or their shareholders. To
date, substantially all of the costs associated with these and other regulatory
matters have been borne by NYLIM. Except as described below, neither NYLIM nor
the funds advised by it have any reason to believe that they have been targeted
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.
Discussions have been held with the SEC concerning a possible resolution of this
matter. These discussions are continuing, but there can be no assurance at this
time as to the outcome of these efforts.

NOTE 8 -- CHANGE IN INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM (UNAUDITED):

On March 8, 2004, KPMG LLP ("KPMG") was selected as the Trust's independent
auditor for the 2004 fiscal year. The selection of KPMG was recommended by the
Trust's Audit Committee, comprised of all Non-Interested Trustees, and was
approved by the Trust's Board of Trustees.

The predecessor independent auditor's reports on the Trust's financial
statements for the period ended October 31, 2003 and year ended December 31,
2002 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 periods, and through the date of engagement of KPMG, there
were no disagreements between 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 periods.

 18   MainStay Money Market Fund


REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Trustees and Shareholders of
The MainStay Funds:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of the MainStay Money Market Fund (the "Fund"),
one of the funds constituting The MainStay Funds, as of October 31, 2004, and
the related statement of operations, statement of changes in net assets and the
financial highlights for the year then ended. These financial statements and
financial highlights are the responsibility of the Fund's management. Our
responsibility is to express an opinion on these financial statements and
financial highlights based on our audit. The statement of changes in net assets
for the period ended October 31, 2003 and the year ended December 31, 2002, and
the financial highlights for the periods presented through October 31, 2003,
were audited by other auditors, whose report dated December 18, 2003 expressed
an unqualified opinion thereon.

We conducted our audit in accordance with the Standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
also includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2004 by correspondence with the custodian and
brokers. As to securities purchased or sold but not yet received or delivered,
we performed other appropriate auditing procedures. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
MainStay Money Market Fund of The MainStay Funds as of October 31, 2004, the
results of its operations, the changes in its net assets and its financial
highlights for the year then ended, in conformity with U.S. generally accepted
accounting principles.

MESSAGE FROM
THE PRESIDENT

During the 12 months ended October 31, 2004, the U.S. stock market advanced, but
its pace and direction were by no means steady. Small- and mid-capitalization
stocks tended to outperform large-cap issues, and value stocks generally
outperformed growth stocks.

Economic activity, as measured by gross domestic product, increased from 4.2% in
the fourth quarter of 2003 to 4.5% in the first quarter of 2004. The pace of
economic growth slowed to 3.3% in the second quar-ter of 2004, and according to
preliminary estimates
from the Bureau of Economic Analysis, gross domes-
tic product grew at a seasonally adjusted annual rate
of 3.9% in the third quarter of 2004.

Interest rates began the reporting period at a low 1.00%. In June 2004, the
Federal Open Market Committee responded to expanding output and improved labor
markets by raising the targeted federal funds rate by 25 basis points. Similar
moves in August and September brought the targeted federal funds rate to 1.75%.
In its September 2004 release, the Federal Open Market Committee affirmed its
belief that monetary policy remained accommodative.

Despite rising interest rates, bond markets generally advanced. High-yield bonds
and emerging-market debt were particularly strong. The U.S. dollar declined
relative to most other currencies, which helped U.S. exporters.

In pursuing its investment objective, each MainStay Fund consistently seeks to
apply a well-defined investment process in all market environments. We believe
that a consistent, disciplined investment approach can help investors make more
prudent and practical decisions regarding their investments.

In the report that follows, you'll find additional information about the market
forces, investment decisions, and individual securities that affected your
MainStay Fund during the 12 months ended October 31, 2004. We thank you for
investing with us, and we look forward to many years of continued service in
your behalf.

Sincerely,

/s/ GARY E. WENDLANDT

Gary E. Wendlandt

President

Performance tables and graphs do not reflect the deduction of taxes that a
shareholder would pay on distributions or Fund-share redemptions. Total returns
reflect change in share price, reinvestment of dividend and capital-gain
distributions, and maximum applicable sales charges explained in this paragraph.
The graphs assume an initial investment of $10,000 and reflect the deduction of
all sales charges that would have applied for the period of investment. Class A
shares are sold with a maximum initial sales charge of 4.5% and an annual 12b-1
fee of .25%. Class B shares are sold with no initial sales charge, are subject
to a contingent deferred sales charge (CDSC) of up to 5% if redeemed within the
first six years of purchase, and have an annual 12b-1 fee of 0.5%. 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 0.5%. From
inception (5/1/86) through 12/31/94 (for Class A, first offered 1/3/95) and
8/31/98 (for Class C, first offered 9/1/98), performance of Class A and C shares
includes the historical performance of Class B shares adjusted to reflect the
applicable sales charge (or CDSC) and fees and expenses for Class A and C
shares.

GRAPHS AND SHOULD BE CAREFULLY READ IN CONJUNCTION WITH THEM.

 4   MainStay Tax Free Bond Fund


1. The Lehman Brothers(R) Municipal Bond Index is an unmanaged index that
   includes approximately 15,000 municipal bonds that are rated Baa or better by
   Moody's and have a maturity of at least two years. Bonds subject to the
   Alternative Minimum Tax or with floating or zero coupons are excluded.
   Results assume reinvestment of all income and capital gains. An investment
   cannot be made directly into an index.
2. The Tax Free Bond Composite Index is an unmanaged index that is comprised of
   the Lehman Brothers(R) Municipal Bond Index and the Lehman Brothers(R)
   Municipal Insured Index weighted 50%/50%. The Lehman Brothers(R) Municipal
   Insured Index includes all the insured bonds in the Lehman Brothers(R)
   Municipal Bond Index with a maturity of at least one year and a rating of Baa
   or better by Moody's. Results assume that all income and capital gains are
   reinvested in the index or indices that produce them. The Tax Free Bond
   Composite Index is considered to be the Fund's broad-based securities-market
   index for comparison purposes. An investment cannot be made directly into an
   index or a composite.
3. Lipper Inc. is an independent fund performance monitor. Results are based on
   total returns with all dividend and capital-gain distributions reinvested.

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

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 data 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 John Fitzgerald and Laurie Walters of
MacKay Shields LLC

WHAT MAJOR FACTORS INFLUENCED THE BOND MARKET DURING THE 12 MONTHS ENDED OCTOBER
31, 2004?

The Federal Reserve maintained the targeted federal funds rate at an
accommodative 1.00% through the first half of the Fund's fiscal year, but for
much of that period, economic signals were mixed. With slack in the labor
markets, slack in manufacturing capacity, and little pricing power in most
industries, it initially appeared that there was little risk of the economy
overheating. In April 2004, however, uniformly firm economic releases challenged
that view. The risk of deflation appeared to be waning, while trend-level growth
appeared sustainable. The consensus was that the Federal Reserve's cautionary
stance would be relatively short-lived. Consistent with market expectations, the
Federal Open Market Committee tightened monetary policy at its June 30, 2004,
meeting by raising the targeted federal funds rate to 1.25%. Another
25-basis-point rate hike followed in August, and yet another in September. These
moves brought the targeted federal funds rate to 1.75% at the end of October
2004.

HOW DID THESE FACTORS AFFECT MUNICIPAL BONDS?

Yields on shorter-maturity municipal bonds rose in lockstep with the rise in the
targeted federal funds rate, while yields on longer-maturity municipal bonds had
mixed performance. Two-year municipal yields rose from 1.3% to 1.9% during the
reporting period, and five-year municipal yields increased from 2.4% to 2.6%.
Yields on 10-year municipal bonds fell from 3.7% to 3.4%, and 30-year municipal
yields dropped from 4.8% to 4.6%.

WHAT EFFECT DID SUPPLY AND DEMAND HAVE ON THE MUNICIPAL BOND MARKET?

Municipal bond issuance totaled $301 million for the first 10 months of 2004--8%
less than the same period a year ago. Issuers had largely exhausted refunding
opportunities during previous waves of issuance, and new-money issuance tapered
off as municipal budgets rebounded from record deficits. At the same time,
demand was fragmented. Many institutional accounts increased their holdings,
finding value in municipal bonds versus other asset classes. Retail investors,
however, appeared reluctant to add to their municipal-bond holdings at
relatively low absolute yield levels. As a result, municipal bonds lagged U.S.
Treasury performance. Still, yields on long-term municipals ended the period at
96% of the yield on long-term Treasury bonds, an attractive valuation from an
historical perspective.

CAN YOU BRIEFLY DESCRIBE THE FUND'S INVESTMENT APPROACH?

The Fund normally invests at least 80% of its net assets in U.S. tax-exempt
securities of any maturity that are, at the time of purchase, rated in one of
the top four categories (or in short-term tax-exempt securities rated in one of
the top three categories) by Moody's or S&P. Not more than 20% of the Fund's net
assets may be invested in unrated tax-exempt securities that we deem to be of
comparable quality. In implementing this strategy, we use a combined approach to
investing that analyzes economic trends and factors pertinent to particular
issuers and securities. We seek to anticipate changes in the general direction
of interest rates, the municipal market as a whole, and specific securities held
by the Fund. Based upon our analysis, we determine optimal duration strategy,
sector weightings, yield curve positioning, and security selection.

WHAT WAS THE FUND'S DURATION STRATEGY DURING THE REPORTING PERIOD?

Overall, the Fund's short-duration bias, held for much of the 12-month reporting
period, detracted from performance, as yields on long-term municipal bonds fell,
even though the Federal Reserve was moving to increase short-term interest
rates. For the first few months of the reporting period, we believed that the
Federal Reserve's accommodative policy would eventually spark job growth and
lead to higher interest rates. Instead, employment growth languished through
March 2004 and interest rates fell moderately. The Fund's short-duration bias
detracted during these months, but it helped when interest rates increased
during April and May. We lengthened the Fund's duration to a neutral position in
June, as 10-year municipal yields had risen to 4.25%, a 100 basis-point increase
from the March lows. We felt that the market was susceptible to retracing part
of this yield spike on any slowdown in economic growth. Yields subsequently did
reverse course, and we returned to a short-duration bias in August, as 10-year
municipal yields fell to 3.8% on inconclusive economic data. Ten-year municipal
yields continued to fall through the end of the 12-month reporting period. As a
result, our duration positioning hurt the Fund's relative results.

Funds that invest in bonds are subject to interest rate, credit, and inflation
risk and can lose principal value when interest rates rise. A portion of income
may be subject to state and local taxes or the alternative minimum tax. 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.

WHAT POSITIONING DECISIONS SIGNIFICANTLY AFFECTED THE FUND'S PERFORMANCE?

The Fund's overweighted position in tobacco settlement asset-backed securities
strengthened performance during the reporting period. Yield spreads in this
sector tightened in response to reduced litigation risk, investors' increased
appetite for higher-yielding credits, stabilized shipment trends, and moribund
issuance. The Fund's overweighted positions in the hospital and housing sectors
also added to the Fund's performance, as yield-starved investors gravitated
toward sectors that offered attractive yields relative to high-grade credits.

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

We reduced the Fund's exposure to tobacco settlement bonds from 5.3% to 1.0% of
net assets, bringing the Fund from an overweighted to an underweighted position
as credit spreads began to reflect several positive developments. Although
litigation uncertainties remain, a preliminary ruling in favor of the New York
attorney general in a lawsuit filed by Freedom Holdings increased the likelihood
that the Master Settlement Agreement will not be found to have violated
antitrust law. The amount of litigation risk priced into these securities was
reduced by the Illinois Supreme Court's decision to hear the Miles litigation
appeal and a U.S. Supreme Court ruling limiting punitive damages.

We also reduced the Fund's holdings in zero-coupon securities from a 3.8%
weighting to a 0.5% weighting in December 2003 and January 2004, when interest
rates were still declining and yield spreads were tighter. This move proved to
be highly beneficial for the Fund, as yield spreads later widened and liquidity
dried up when interest rates rose in April and May of 2004.

ARE STATE BUDGET DEFICITS STILL A CONCERN?

The improving economy has led to a sharp turnaround in state finances. According
to the National Conference of State Legislators, state budgets for the 2005
fiscal year, which began in July 2004, now collectively have a projected deficit
of $36 billion, a 54% decrease from the previous fiscal year. Although there is
still work to be done, service and payroll reductions and higher taxes have
helped. The National Conference of State Legislators reports that more than half
of the states are recording increased corporate income taxes, and the
Rockefeller Institute of Government reported an 8% increase in sales-tax
collections in the quarter ended September 30, 2004, compared with the same
period last year.

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

The U.S. economy continues to post solid numbers, both on the demand and supply
sides, although recent data has been decelerating from earlier high
post-recession levels. We expect the sum total of the economic data will lead
the Federal Open Market Committee to raise the targeted federal funds rate to 2%
by year-end 2004 and to 2.5% by March 2005. As we move toward 2005, we feel that
a pickup in economic growth is a reasonable assumption given low interest rates,
lower marginal tax rates, low inflation, firm consumer spending patterns, and
improved corporate confidence.

HOW WILL YOU POSITION THE FUND GOING FORWARD?

Given our view of the economy and interest rates, as well as the need for
increased Treasury issuance to fund the federal budget imbalance, we intend to
maintain the Fund's shorter-than-benchmark duration for the near term. We
currently favor callable premium bonds in the 15-year maturity range that offer
attractive yields relative to their risks and that are expected to outperform in
a rising rate environment. Of course, we will continue to monitor key economic
data over the next few months to determine whether our defensive Fund posture is
justified.

NOTES TO FINANCIAL STATEMENTS

NOTE 1 -- ORGANIZATION AND BUSINESS:

The MainStay Funds (the "Trust") was organized on January 9, 1986 as a
Massachusetts business trust. The Trust is registered under the Investment
Company Act of 1940, as amended (the "1940 Act"), as an open-end management
investment company and comprises twenty-two funds (collectively referred to as
the "Funds"). These financial statements and notes relate only to MainStay Tax
Free Bond Fund (the "Fund"), a diversified fund.

The Fund currently offers three classes of shares. Class A shares, whose
distribution commenced on January 3, 1995, 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 within one year of purchase of Class C
shares. Distribution of Class B shares and Class C shares commenced on May 1,
1986 and September 1, 1998, respectively. Class A shares, Class B shares and
Class C shares bear the same voting (except for issues that relate solely to one
class), dividend, liquidation and other rights and conditions except that the
Class B shares and Class C shares are subject to higher distribution fee rates.
Each class of shares bears distribution and/or service fee payments under a
distribution plan pursuant to Rule 12b-1 under the 1940 Act.

The Fund's investment objective is to provide a high level of current income
free from regular federal income tax, consistent with the preservation of
capital.

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

NOTE 2 -- SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with generally accepted
accounting principles and follows the significant accounting policies described
below.

(A) SECURITIES VALUATION.  Debt securities are valued at prices supplied by a
pricing agent selected by the Fund's Manager, whose prices reflect broker/dealer
supplied valuations and electronic data processing techniques, if those prices
are deemed by the Fund's Manager to be representative of market values, at the
regular close of business of the New York Stock Exchange. Futures contracts are
valued at the last posted settlement price on the market where such futures 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.
Securities for which market quotations are not readily available are valued by
methods deemed by the Board of Trustees to represent fair value. Reasons for
which securities may be valued in this manner include, but are not limited to,
trading for a security has been halted or suspended, a security has been
de-listed from a national exchange, or trading on a security's primary market is
temporarily closed at a time when under normal conditions it would be open. The
Fund did not hold securities at October 31, 2004, that were valued in such
manner.

(B) 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. During the period the futures contract is open, changes in the value of
the contract are recognized as unrealized gains or losses by "marking to market"
such contract on a daily basis to reflect the market value of the contract at
the end of each day's trading. The Fund agrees to receive from or pay to the
broker an amount of cash equal to the daily fluctuation in the value of the
contract. Such receipts or payments are known as "variation margin." When the
futures contract is closed, the Fund records a realized gain or loss equal to
the difference between the proceeds from (or cost of) the closing transaction
and the Fund's basis in the contract. The Fund may enter into contracts for the
future delivery of debt securities in order to attempt to protect against the
effects of adverse changes in interest rates, to lengthen or shorten the average
maturity or duration of the Fund's portfolio or to try to enhance the Fund's
returns.

The use of futures contracts involves, to varying degrees, elements of market
risk in excess of the amount recognized in the statement of assets and
liabilities. The contract or notional amounts and variation margin reflect the
extent of the Fund's involvement in open futures positions. Risks arise from the
possible imperfect correlation in movements in the price of futures contracts,
interest rates and the underlying hedged assets, and the possible inability of
counterparties to meet the terms of their contracts. However, the Fund's
activities in futures contracts are conducted through regulated exchanges which
minimize counterparty credit risks.

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

 20   MainStay Tax Free Bond Fund


(D) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are
recorded on the ex-dividend date. The Fund intends to declare and pay dividends
monthly and capital gain distributions, if any, annually. 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.

The following table discloses the current year reclassifications between
accumulated undistributed net investment income, accumulated realized loss and
additional paid-in-capital arising from permanent differences; net assets at
October 31, 2004 are not affected.

<Table>
<Caption>
  UNDISTRIBUTED    ACCUMULATED    ADDITIONAL
  NET INVESTMENT   NET REALIZED     PAID-IN
      INCOME           LOSS         CAPITAL
                            
      $1,496        $3,256,249    $(3,257,745)
</Table>

The reclassifications for the Fund are primarily due to a reclassification of
distributions and expiration of capital loss carryforward.

(E) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  The Fund records security
transactions on the trade date. Realized gains and losses on security
transactions are determined using the identified cost method. Interest income is
accrued as earned. Discounts and Premiums on securities purchased by the Fund
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.

The investment income and realized and unrealized gains and losses on
investments of the 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.

(F) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred except where direct allocations of expenses can be made. Expenses
(other than expenses incurred under the distribution plans) are allocated to
separate classes of shares based upon their relative net asset value on the date
the expenses are incurred. The expenses borne by the Fund, including those of
related parties to the Fund, are shown in the Statement of Operations.

(G) USE OF ESTIMATES.  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.

NOTE 3 -- FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER AND SUBADVISOR.  New York Life Investment Management LLC ("NYLIM" or
the "Manager"), an indirect wholly-owned subsidiary of New York Life Insurance
Company, serves as the Fund's manager. The Manager provides offices, conducts
clerical, recordkeeping and bookkeeping services, and keeps the financial and
accounting records required for the Fund. The Manager also pays the salaries and
expenses of all personnel affiliated with the Fund and all the operational
expenses that are not the responsibility of the Fund. MacKay Shields LLC (the
"Subadvisor"), a registered investment adviser and indirect wholly-owned
subsidiary of New York Life, is responsible for the day-to-day portfolio
management of the Fund.

Through July 31, 2004, the Trust, on behalf of the Fund, paid the Manager a
monthly fee for services performed and the facilities furnished at an annual
rate of 0.60% of the Fund's average daily net assets on assets up to $1 billion
and 0.55% on assets in excess of $1 billion. Effective as of August 1, 2004,
NYLIM has voluntarily agreed to waive its management fee by 0.15% of the Fund's
average daily net assets. In addition, effective December 1, 2004, NYLIM has
voluntarily agreed to reimburse the expenses of the Fund to the extent that
operating expenses would exceed on an annualized basis 0.89%, 1.14% and 1.14% of
the average daily net assets of the Class A, Class B and Class C shares,
respectively. For the year ended October 31, 2004, the Manager earned from the
Fund $1,944,180 and waived $115,751 of its management fee.

Pursuant to the terms of a Sub-Advisory Agreement between NYLIM and MacKay
Shields, the Manager paid the Subadvisor a monthly fee at an annual rate of
0.30% of the average daily net assets of the Fund. To the extent the Manager has
agreed to reimburse expenses of the Fund, the Subadvisor has voluntarily agreed
to do so proportionately.

(B) DISTRIBUTION AND SERVICE FEES.  The Trust, on behalf of the Fund, has a
Distribution Agreement with NYLIFE Distributors LLC (the "Distributor"). The
Fund, with respect to each class of shares, has adopted distribution plans (the
"Plans") in accordance with the provisions of Rule 12b-1 under the 1940 Act.
Pursuant to the Class A Plan, the Distributor receives a monthly fee from the
Fund at an annual rate of 0.25% of the average daily net assets

                                                    www.mainstayfunds.com     21

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

of the Fund's Class A shares, which is an expense of the Class A shares of the
Fund for distribution or service activities as designated by the Distributor.
Pursuant to the Class B and Class C Plans, the Fund pays the Distributor a
monthly fee, which is an expense of the Class B and Class C shares of the Fund,
at the annual rate of 0.25% of the average daily net assets of the Fund's Class
B and Class C shares. The distribution plans provide that the Class B and Class
C shares of the Fund 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 Fund.

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

(C) SALES CHARGES.  The Fund was advised by the Distributor that the amount of
sales charges retained on sales of Class A shares was $13,056 for the year ended
October 31, 2004. The Fund was also advised that the Distributor retained
contingent deferred sales charges on redemptions of Class A, Class B and Class C
shares of $468, $103,635 and $3,255, respectively, for the year ended October
31, 2004.

(D) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT.  NYLIM
Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's
transfer, dividend disbursing and shareholder servicing agent. NYLIM Service has
entered into an agreement with Boston Financial Data Services ("BFDS") pursuant
to which BFDS will perform certain of the services for which NYLIM Service is
responsible. Transfer agent expense for the year ended October 31, 2004 amounted
to $313,032.

(E) NON-INTERESTED TRUSTEES FEES.  Non-Interested Trustees are paid an annual
retainer fee of $45,000, $2,000 for each Board meeting, $1,000 for each
Committee meeting and $500 for each Valuation Subcommittee telephonic meeting
attended plus reimbursement for travel and out-of-pocket expenses. The Lead
Non-Interested Trustee is also paid an annual retainer fee of $20,000. The Audit
Committee Chairman receives an additional $2,000 for each meeting of the Audit
Committee attended and the Chairpersons of the Brokerage Committee, Operations
Committee and Performance Committee each receive an additional $1,000 for each
meeting of the Brokerage Committee, Operations Committee and Performance
Committee attended, respectively. In addition, each Non-Interested Trustee is
paid $1,000 for attending meetings of the Non-Interested Trustees held in
advance of or in connection with Board/Committee meetings. The Trust allocates
trustees fees in proportion to the net assets of the respective Funds. Thus the
Tax Free Bond Fund only pays a portion of the fees identified above.

(F) OTHER.  Fees for the cost of legal services, included in Professional Fees
as shown on the Statement of Operations, provided to the Fund by the Office of
the General Counsel of NYLIM amounted to $9,481 for the year ended October 31,
2004.

The Fund pays the Manager a monthly fee for recordkeeping services provided
under the Accounting Agreement at the annual rate of 1/20 of 1% for the first
$20 million of average monthly net assets, 1/30 of 1% of the next $80 million of
average monthly net assets and 1/100 of 1% of any amount in excess of $100
million of average monthly net assets. Fees for recordkeeping services provided
to the Fund by the Manager amounted to $59,078 for the year ended October 31,
2004.

NOTE 4 -- CUSTODIAN:

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

NOTE 5 -- FEDERAL INCOME TAX:

The Fund has maintained its year end of December 31 for federal income tax
purposes.

At October 31, 2004, the components of accumulated loss on a tax basis were as
follows:

    $250,739      $(36,085,014)  $23,154,735    $(12,679,540)
</Table>

At October 31, 2004, for federal income tax purposes, capital loss carryforwards
of $36,085,014 were available, as shown in the table below, to the extent
provided by the regulations, to offset future realized gains 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 7 -- LINE OF CREDIT:

The Fund and certain affiliated funds maintain a line of credit of $160,000,000
with a syndicate of banks in order to secure a source of funds for temporary

amount, regardless of usage, to The Bank of New York, which acts as agent to the
syndicate. Such commitment fees are allocated among the funds based upon net
assets and other factors. Interest on any revolving credit loan is charged based
upon the Federal Funds Advances rate. There were no borrowings on the line of
credit during the year ended October 31, 2004.

NOTE 9 -- OTHER MATTERS:

NYLIM and mutual funds that NYLIM advises have received requests for information
from various government authorities and regulatory bodies regarding market
timing, late trading, operations, fees, expenses, and other matters. NYLIM and
the funds it advises are cooperating fully in responding to these requests. As
reported in response to those requests for information, NYLIM was previously
party to agreements with certain registered representatives of broker-dealers
relating to the level of trading by clients or customers of those registered
representatives in shares of certain funds of the Trust. NYLIM is continuing to
review what effect, if any, transactions under these agreements may have had on
the funds, and will continue to apprise the Board of Trustees of such
information. NYLIM does not believe at this time that such trading had any
material effect on the funds' financial statements or their shareholders. To
date, substantially all of the costs associated with these and other regulatory
matters have been borne by NYLIM. Except as described below, neither NYLIM nor
the funds advised by it have any reason to believe that they have been targeted
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.
Discussions have been held with the SEC concerning a possible resolution of this
matter. These discussions are continuing, but there can be no assurance at this
time as to the outcome of these efforts.

NOTE 10 -- CHANGE IN INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM (UNAUDITED):

On March 8, 2004, KPMG LLP ("KPMG") was selected as the Trust's independent
auditor for the 2004 fiscal year. The selection of KPMG was recommended by the
Trust's Audit Committee, comprised of all Non-Interested Trustees, and was
approved by the Trust's Board of Trustees.

The predecessor independent auditor's report on the Trust's financial statements
for the period ended October 31, 2003 and year ended December 31, 2002 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 periods, and through the date of engagement of KPMG, there were no
disagreements between 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 periods.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Trustees and Shareholders of
The MainStay Funds:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of the MainStay Tax Free Bond Fund (the "Fund"),
one of the funds constituting The MainStay Funds, as of October 31, 2004, and
the related statement of operations, statement of changes in net assets and the
financial highlights for the year then ended. These financial statements and
financial highlights are the responsibility of the Fund's management. Our
responsibility is to express an opinion on these financial statements and
financial highlights based on our audit. The statement of changes in net assets
for the period ended October 31, 2003 and the year ended December 31, 2002, and
the financial highlights for the periods presented through October 31, 2003,
were audited by other auditors, whose report dated December 18, 2003 expressed
an unqualified opinion thereon.

We conducted our audit in accordance with the Standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
also includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2004 by correspondence with the custodian and
brokers. As to securities purchased or sold but not yet received or delivered,
we performed other appropriate auditing procedures. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
MainStay Tax Free Bond Fund of The MainStay Funds as of October 31, 2004, the
results of its operations, the changes in its net assets and its financial
highlights for the year then ended, in conformity with U.S. generally accepted
accounting principles.

MESSAGE FROM
THE PRESIDENT

During the 12 months ended October 31, 2004, the U.S. stock market advanced, but
its pace and direction were by no means steady. Small- and mid-capitalization
stocks tended to outperform large-cap issues, and value stocks generally
outperformed growth stocks.

Economic activity, as measured by gross domestic product, increased from 4.2% in
the fourth quarter of 2003 to 4.5% in the first quarter of 2004. The pace of
economic growth slowed to 3.3% in the second quarter of 2004, and according to
preliminary estimates from the Bureau of Economic Analysis, gross domestic
product grew at a seasonally adjusted annual rate of 3.9% in the third quarter
of 2004.

Interest rates began the reporting period at a low 1.00%. In June 2004, the
Federal Open Market Committee responded to expanding output and improved labor
markets by raising the targeted federal funds rate by 25 basis points. Similar
moves in August and September brought the targeted federal funds rate to 1.75%.
In its September 2004 release, the Federal Open Market Committee affirmed its
belief that monetary policy remained accommodative.

Despite rising interest rates, bond markets generally advanced. High-yield bonds
and emerging-market debt were particularly strong. The U.S. dollar declined
relative to most other currencies, which helped U.S. exporters.

In pursuing its investment objective, each MainStay Fund consistently seeks to
apply a well-defined investment process in all market environments. We believe
that a consistent, disciplined investment approach can help investors make more
prudent and practical decisions regarding their investments.

In the report that follows, you'll find additional information about the market
forces, investment decisions, and individual securities that affected your
MainStay Fund during the 12 months ended October 31, 2004. We thank you for
investing with us, and we look forward to many years of continued service in
your behalf.

Sincerely,

- -s- GARY E. WENDLANDT

Gary E. Wendlandt

President

Performance tables and graphs do not reflect the deduction of taxes that a
shareholder would pay on distributions or Fund-share redemptions. Total returns
reflect change in share price, reinvestment of dividend and capital-gain
distributions, and maximum applicable sales charges explained in this paragraph.
The graphs assume an initial investment of $10,000 and reflect the deduction of
all sales charges that would have applied for the period of investment. Class A
shares are sold with a maximum initial sales charge of 5.5% and an annual 12b-1
fee of .25%. Class B shares are sold with no initial sales charge, are subject
to a contingent deferred sales charge (CDSC) of up to 5% if redeemed within the
first six years of purchase, and have an annual 12b-1 fee of 1.00%. Class C
shares are sold with no initial sales charge, are subject to a CDSC of 1% if
redeemed within one year of purchase, and have an annual 12b-1 fee of 1.00%.
Class I shares are sold with no initial sales charge or CDSC, have no annual
12b-1 fee, and are generally available to corporate and institutional investors
with a minimum initial investment of $5 million. From inception (12/19/97)
through 12/31/94 (for Class A, first offered 1/3/95), 8/31/98 (for Class C,
first offered 9/1/98), and 12/31/03 (for Class I, R1, and R2, first offered
1/2/04), performance of Class A, C, I, R1, and R2 shares includes the historical
performance of Class B shares adjusted to reflect the applicable sales charge
(or CDSC) and fees and expenses for Class A, C, I, R1, and R2 shares.

1. The Total Return Growth Composite Index is comprised of the Russell 1000(R)
   Growth Index and the Lehman Brothers(R) Aggregate Bond Index weighted
   60%/40%, respectively. The Russell 1000(R) Growth Index is an unmanaged index
   that measures the performance of those Russell 1000(R) companies with higher
   price-to-book ratios and higher forecasted growth values. The Russell 1000(R)
   Index is an unmanaged index that measures the performance of the 1,000
   largest U.S. companies based on total market capitalization. The Lehman
   Brothers(R) Aggregate Bond Index includes fixed-rate debt issues rated
   investment grade or higher by Moody's, S&P, or Fitch. All issues must have at
   least one year left to maturity and have an outstanding par value of at least
   $100 million. The Index is comprised of the Lehman Brothers(R)
   Government/Corporate, the Mortgage-Back Securities, and the Asset-Backed
   Securities Indices. Results assume that all income and capital gains are
   reinvested in the index that produced them. An investment cannot be made
   directly into an index.
2. The Total Return Core Composite Index is comprised of the Russell 1000(R)
   Index and the Lehman Brothers(R) Aggregate Bond Index weighted 60%/40%,
   respectively. The Russell 1000(R) Index is an unmanaged index that measures
   the performance of the 1,000 largest U.S. companies based on total market
   capitalization. See footnote 1 for more information about the Lehman
   Brothers(R) Aggregate Bond Index. Results assume that all income and capital
   gains are reinvested in the index that produced them. The Total Return Core
   Composite Index is considered to be the Fund's broad-based securities-market
   index for comparison purposes. An investment cannot be made directly into an
   index.
3. "S&P 500(R)" is a trademark of The McGraw-Hill Companies, Inc. The S&P 500(R)
   is an unmanaged index and is widely regarded as the standard for measuring
   large-cap U.S. stock-market performance. Results assume reinvestment of all
   income and capital gains. An investment cannot be made directly into an
   index.

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

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 data 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 Rudolph C. Carryl, Gary Goodenough,
Christopher Harms, Richard A. Rosen, and Edmund C. Spelman of MacKay Shields LLC

CAN YOU BRIEFLY DESCRIBE THE FUND'S INVESTMENT APPROACH?

The Fund invests a minimum of 30% of its assets in U.S. equity securities and a
minimum of 30% in U.S. debt securities. In implementing this investment
strategy, about half of the equity portion of the Fund's portfolio is invested
in growth-oriented stocks and about half in stocks that the Fund believes to be
undervalued. The bond portion of the Fund's portfolio may purchase high-yield
bonds and other debt securities rated below investment grade that we believe may
provide capital appreciation in addition to income. Both the stock and bond
portions of the Fund's portfolio may take a flexible approach by investing in a
variety of securities, industries, and issuers.

HOW HAS THE FUND'S PORTFOLIO-MANAGEMENT MANDATE CHANGED?

As of January 1, 2004, Richard A. Rosen joined the Fund's portfolio-management
team. From January through April 2004, the equity portion of the Fund's
portfolio gradually shifted to include both growth and value stocks. As outlined
in the prospectus supplement dated May 17, 2004, the Fund's ability to invest in
high-yield securities has been enhanced.

WHAT FACTORS AFFECTED THE STOCK MARKET DURING THE 12 MONTHS ENDED OCTOBER 31,
2004?

Arguably the biggest factor was the 78% rise in the price of crude oil, since it
stoked inflation fears and could put a damper on consumer spending. Middle
Eastern tensions, news from Iraq, and concerns about another domestic terrorist
attack all had an impact on the markets. Equities finished the reporting period
on a strong note as the national elections approached, energy prices eased
somewhat, and investors appeared to view valuations more positively.

WHICH SECTORS WERE STRONG PERFORMERS FOR THE EQUITY PORTION OF THE PORTFOLIO?

The equity portion of the portfolio includes growth and value components. The
value component was added to the Fund's portfolio beginning in January 2004. In
the growth component, overweighted positions in energy and industrials and good
stock selection in these sectors helped performance. Security selection in the
consumer staples and consumer discretionary sectors and an underweighted
position in the information technology sector detracted from performance. In the
value component of the Fund's portfolio, mediocre individual-stock performance
in the materials, financials, and health care sectors offset positive
contributions from holdings in energy and information technology.

WHICH INDIVIDUAL STOCKS WERE STRONG PERFORMERS?

Among growth stocks, Symantec, UnitedHealth Group, Danaher, Illinois Tool Works,
and Harley-Davidson all made substantial positive contributions to performance.
In the value component of the equity portion of the portfolio, we saw strong
performance from Burlington Northern Santa Fe, Boeing, and Coopers Industries,
and we reduced these positions as they approached our price targets. CVS
advanced on strong sales trends and the acquisition of Eckerd stores in Texas
and Florida. In the energy sector, we saw strong results from ConocoPhillips,
Transocean, Kerr-McGee, and Diamond Offshore Drilling. We reduced the Fund's
positions in Kerr-McGee and Diamond Offshore Drilling as they approached our
price targets. Other value-oriented stocks that did well in the Fund included
Computer Sciences, Motorola, and Sprint.

WHICH STOCKS PROVIDED POOR PERFORMANCE?

On the growth side, VERITAS Software, New York Community Bancorp, Intel, Applied
Materials, and Texas Instruments all detracted from performance. On the value
side, Marsh & McLennan, St. Paul Travelers, Merck, Pfizer, HCA, and Bowater all
hurt performance. Truck manufacturer Navistar International also took a toll on
performance.

WERE THERE SIGNIFICANT PURCHASES IN THE EQUITY PORTION OF THE PORTFOLIO?

On the growth side, we purchased Harmon International in October for the
company's improving sales and earnings growth and market penetration. Other
significant purchases included L-3 Communications Holdings, NIKE, Best Buy, and
Capital One Financial. All of these stocks had a positive impact on the Fund's
performance for the portion of the reporting period they were held in the Fund.
The entire value component of the equity portion of the portfolio was initiated
during the reporting period.

High-yield securities ("junk bonds") are generally considered speculative
because they present a greater risk of loss than higher-quality debt securities
and may be subject to greater price volatility. The Fund may invest in
derivatives, which may increase the Fund's net asset value and may result in a
loss to the Fund. Funds that invest in bonds are subject to credit, inflation,
and interest-rate risk and can lose principal value when interest rates rise.

WHICH EQUITY POSITIONS DID YOU SELL OR REDUCE DURING THE REPORTING PERIOD?

In the growth component, we began selling Marsh & McLennan in December of 2003
because of slowing growth and losses in the company's Putnam mutual fund unit.
When the New York attorney general began an investigation of the company, the
sale proved timely. We sold the Fund's position in New York Community Bancorp in
October. Other growth-oriented stock sales included Clear Channel
Communications, Coca-Cola, Forrest Laboratories, and Fifth Third Bancorp. In the
value component, we reduced several positions that showed weak performance,
including Marsh & McLennan, Pfizer, HCA, and Navistar International. Other
holdings--such as Burlington Northern Santa Fe, Boeing, Cooper Industries,
ConocoPhillips, Diamond Offshore Drilling, and Kerr-McGee--were reduced as they
advanced and approached our price targets.

HOW WAS THE EQUITY PORTION OF THE PORTFOLIO POSITIONED AS OF OCTOBER 31, 2004?

At the end of October, the growth-equity component of the Fund's portfolio was
overweighted relative to the Russell 1000(R) Growth Index(1) in the consumer
discretionary, energy, industrials, and materials sectors. The growth component
was underweighted relative to the Russell 1000(R) Growth Index in consumer
staples, financials, health care, and information technology, and it held no
positions in the telecommunications services or utilities sectors. At the end of
the reporting period, the value-equity component of the Fund's portfolio was
overweighted in the consumer staples, energy, health care, and materials
sectors, and underweighted in the consumer discretionary, financials, and
utilities sectors.

WHAT MAJOR FACTORS AFFECTED THE BOND MARKET DURING THE 12 MONTHS ENDED OCTOBER
31, 2004?

From November 2003 through early April 2004, the Federal Reserve's accommodative
1.00% target for the federal funds rate kept the market relatively benign.
Positive economic reports in April, however, suggested that the Federal Open
Market Committee might move to tighten the money supply. In line with
expectations, the Federal Open Market Committee raised the targeted federal
funds rate by 25 basis points on each of three occasions--in June, August, and
September. This raised the targeted federal funds rate to 1.75%. During the
reporting period, inflation remained subdued, despite high oil prices. Default
rates declined, which helped attract investors to higher-yielding instruments.
Several foreign central banks purchased large blocks of U.S. Treasuries in an
effort to keep their currencies from rising aggressively against the dollar.

HOW DID THE BOND PORTION OF THE FUND'S PORTFOLIO PERFORM DURING THE REPORTING
PERIOD?

Quite well. The bond portion of the portfolio outperformed the Lehman
Brothers(R) Aggregate Bond Index(2) (the bond component of the Fund's composite
benchmarks) by a substantial margin. Much of the strong performance came from
asset allocation. As of October 31, 2004, the bond portion of the Fund held 5%
of its assets in Treasuries, 13% in agency debentures, 26% in investment-grade
corporates, 14% in high-yield corporates, 33% in residential mortgage-backed
securities, 3% in commercial mortgage-backed securities, 4% in asset-backed
securities, and 2% in money-market instruments. Relative to the Lehman
Brothers(R) Aggregate Bond Index, the Fund was heavily overweighted in
high-yield corporates and heavily underweighted in Treasuries.

HOW HAVE YOU POSITIONED THE BOND PORTION OF THE FUND?

The portfolio is positioned to reflect our forward-looking views. We are seeking
the yield advantages of moderate- and lower-quality corporate bonds relative to
Treasuries and agency securities. Within residential mortgage-backed securities,
we favor lower-coupon securities and 15-year loan terms for their less-volatile
cash flow profiles. Among asset-backed securities, we prefer
non-mortgage-related collateral such as auto loans, credit-card receivables, and
electric-utility tariffs. We are cautious about agency debentures in light of
their small yield advantages and potential vulnerability to additional
regulation. During the reporting period, we took profits on 3% of the Fund's
high-yield position and rotated the proceeds into higher-quality commercial
mortgage-backed securities and corporate bonds.

HOW DID YOU POSITION THE BOND PORTION OF THE FUND'S PORTFOLIO IN TERMS OF
DURATION?

For much of the reporting period, the bond portion of the Fund's duration was
slightly shorter than that of the Lehman Brothers(R) Aggregate Bond Index. This
seemed reasonable since interest rates were expected to rise, but it worked
against the Fund when foreign central banks began purchasing large blocks of

   Index.

   Aggregate Bond Index.

U.S. Treasuries to protect their local economies against unfavorable currency
movements.

DID THE RESHAPING OF THE YIELD CURVE AFFECT THE PERFORMANCE OF THE BOND PORTION
OF THE FUND'S PORTFOLIO?

Not significantly. Although the yield curve flattened slightly over the course
of the reporting period, we maintained a relatively neutral yield-curve posture,
so the reshaping had a minimal impact.

WHICH BOND SECTORS PROVIDED THE GREATEST CONTRIBUTIONS TO THE FUND'S RETURN?

The bond portion of the Fund's portfolio was able to harvest strong excess
returns from prudent risk-taking and savvy issue selection in triple-B rated
corporates, high-yield corporates, and emerging-market credits. During the
period, the Fund's positions in credit-related product contributed the majority
of the excess return in the bond portion of the portfolio. The balance of the
excess return came from mortgage-backed and asset-backed securities, which
showed strong performance while Treasury yields remained range bound.

WHAT DO YOU SEE GOING FORWARD?

With the uncertainty of the presidential election now behind us, we expect
investors to refocus their attention on company and market fundamentals, which
on balance remain fairly strong. Although high energy prices and the threat of
terrorism remain risk factors, we believe that the combination of a low
interest-rate environment, moderate economic growth, and strengthening
employment should help to drive stocks higher in the coming year. From a bond
perspective, we expect that the Federal Open Market Committee will continue to
raise the targeted federal funds rate well into the coming year and that
additional Treasury issuance will be needed to fund the federal budget
imbalance. We may maintain a short-of-neutral duration in the bond portion of
the Fund's portfolio. If our outlook changes, it would likely be reflected in
our duration positioning. We will likely maintain a generous exposure to
corporate bonds and securitized product as long as we see robust demand for
products that offer yield advantages relative to Treasuries.

NOTES TO FINANCIAL STATEMENTS

NOTE 1 -- ORGANIZATION AND BUSINESS:

The MainStay Funds (the "Trust") was organized on January 9, 1986 as a
Massachusetts business trust. The Trust is registered under the Investment
Company Act of 1940, as amended (the "1940 Act"), as an open-end management
investment company and comprises twenty-two funds (collectively referred to as
the "Funds"). These financial statements and notes relate only to MainStay Total
Return Fund (the "Fund"), a diversified fund.

The Fund currently offers four classes of shares. Class A shares, whose
distribution commenced on January 3, 1995, 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 within one year of purchase of Class C
shares. Distribution of Class B shares and Class C shares commenced on December
29, 1987 and September 1, 1998, respectively. Class I shares are not subject to
sales charge. Distribution of Class I shares commenced on January 2, 2004. Class
A shares, Class B shares, Class C shares and Class I shares bear the same voting
(except for issues that relate solely to one class), dividend, liquidation and
other rights and conditions. Each class of shares, other than Class I shares,
bears distribution and/or service fee payments under a distribution plan
pursuant to Rule 12b-1 under the 1940 Act. Class I shares are not subject to a
distribution or service fee.

The Fund's investment objective is to realize current income consistent with
reasonable opportunity for future growth of capital and income.

The Fund also invests in foreign securities which carry certain risks in
addition to the usual risks inherent in domestic instruments. These risks
include those resulting from currency fluctuations, future adverse political and
economic developments and possible imposition of currency exchange blockages or
other foreign governmental laws or restrictions. The ability of issuers of debt
securities held by the Fund to meet their obligations may be affected by
economic and political developments in a specific industry or region.

NOTE 2 -- SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with generally accepted
accounting principles and follows the significant accounting policies described
below.

(A) SECURITIES VALUATION.  Equity securities are valued at the latest quoted
sales prices as of the close of 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
selected by the Fund's Manager, whose prices reflect broker/dealer supplied
valuations and electronic data processing techniques if those prices are deemed
by the Fund's Manager to be representative of market values at the regular close
of business of the New York Stock Exchange. 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. Securities for which market quotations are not
readily available are valued by methods deemed by the Board of Trustees to
represent fair value. Reasons for which securities may be valued in this manner
include, but are not limited to, trading for a security has been halted or
suspended, a security has been de-listed from a national exchange, or trading on
a security's primary market is temporarily closed at a time when under normal
conditions it would be open. The Fund did not hold securities at October 31,
2004, that were valued in such manner.

(B) MORTGAGE DOLLAR ROLLS.  The fund enters into mortgage dollar roll ("MDR")
transactions for which it sells mortgage-backed securities ("MBS") from its
portfolio to a counterparty from whom it simultaneously agrees to buy a similar
security on a delayed delivery basis. The MDR transactions of the Fund are
classified as purchase and sale transactions. The securities sold in connection
with the MDRs are removed from the portfolio and a realized gain or loss is
recognized. The securities the Fund has agreed to acquire are included at market
value in the portfolio of investments and liabilities for such purchase
commitments are included as payables for investments purchased. 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.

(C) SECURITIES LENDING.  The 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

 28   MainStay Total Return Fund


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.

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

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

(E) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are
recorded on the ex-dividend date. The Fund intends to declare and pay dividends
quarterly and capital gain distributions, if any, annually. 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.

The following table discloses the current year reclassification between
accumulated undistributed net investment income and accumulated net realized
gain on investments arising from permanent differences; net assets at October
31, 2004, are not affected.

<Table>
<Caption>
  ACCUMULATED UNDISTRIBUTED   ACCUMULATED NET REALIZED
    NET INVESTMENT INCOME       GAIN ON INVESTMENTS
                           
          $107,269                   $(107,269)
</Table>

The reclassifications for the Fund are primarily due to foreign currency gain,
premium amortization adjustments and paydown gain (loss).

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

(G) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred except where direct allocations of expenses can be made. Expenses
(other than expenses incurred under the distribution plans) are allocated to
separate classes of shares based upon their relative net asset value on the date
the expenses are incurred. The expenses borne by the Fund, including those of
related parties to the Fund, are shown in the Statement of Operations.

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

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

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

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

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

(I) 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.

NOTE 3 -- FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER AND SUBADVISOR.  New York Life Investment Management LLC ("NYLIM" or
the "Manager"), an indirect wholly-owned subsidiary of New York Life Insurance
Company ("New York Life"), serves as the Fund's manager. The Manager provides
offices, conducts clerical, recordkeeping and bookkeeping services, and keeps
the financial and accounting records required for the Fund. The Manager also
pays the salaries and expenses of

                                                    www.mainstayfunds.com     29

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

all personnel affiliated with the Fund and all the operational expenses that are
not the responsibility of the Fund. MacKay Shields LLC (the "Subadvisor"), a
registered investment advisor and indirect wholly-owned subsidiary of New York
Life, is responsible for the day-to-day portfolio management of the Fund.

The Trust, on behalf of the Fund, pays the Manager a monthly fee for services
performed and the facilities furnished at an annual rate of 0.64% of the Fund's
average daily net assets on assets up to $500 million and 0.60% annually on
assets in excess of $500 million. Effective December 1, 2004, NYLIM has
voluntarily agreed to reimburse the expenses of the Fund to the extent that
operating expenses would exceed on an annualized basis 1.19%, 1.94% and 1.94% of
the average daily net assets of the Class A, Class B and Class C shares,
respectively and an equivalent reduction in the management fee for Class I. For
the year ended October 31, 2004, the Manager earned from the Fund $5,802,586.

Pursuant to the terms of a Sub-Advisory Agreement between NYLIM and MacKay
Shields, the Manager paid the Subadvisor a monthly fee at an annual rate of
0.32% of the average daily net assets of the Fund on assets up to $500 million
and 0.30% on assets in excess of $500 million. To the extent the Manager has
agreed to reimburse expenses of the Fund, the Subadvisor has voluntarily agreed
to do so proportionately.

(B) DISTRIBUTION AND SERVICE FEES.  The Trust, on behalf of the Fund, has a
Distribution Agreement with NYLIFE Distributors LLC (the "Distributor"), an
indirect wholly-owned subsidiary of New York Life. The Fund, with respect to
each class of shares other than Class I shares, has adopted distribution plans
(the "Plans") in accordance with the provisions of Rule 12b-1 under the 1940
Act. Pursuant to the Class A Plan, the Distributor receives a monthly fee from
the Fund at an annual rate of 0.25% of the average daily net assets of the
Fund's Class A shares, which is an expense of the Class A shares of the Fund for
distribution or service activities as designated by the Distributor. Pursuant to
the Class B and Class C Plans, the Fund pays the Distributor a monthly fee,
which is an expense of the Class B and Class C shares of the Fund, at the annual
rate of 0.75% of the average daily net assets of the Fund's Class B and Class C
shares. The distribution plans provide that the Class B and Class C shares of
the Fund 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 Fund. Class I
shares are not subject to a distribution or service fee.

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

(C) SALES CHARGES.  The Fund was advised by the Distributor that the amount of
sales charges retained on sales of Class A shares was $33,824 for the year ended
October 31, 2004. The Fund was also advised that the Distributor retained
contingent deferred sales charges on redemptions of Class A, Class B and Class C
shares of $7,776, $330,990 and $1,101, respectively, for the year ended October
31, 2004.


(D) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT.  NYLIM
Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's
transfer, dividend disbursing and shareholder servicing agent. NYLIM Service has
entered into an agreement with Boston Financial Data Services ("BFDS") pursuant
to which BFDS will perform certain of the services for which NYLIM Service is
responsible. Transfer agent expenses for the year ended October 31, 2004,
amounted to $3,220,030.

(E) NON-INTERESTED TRUSTEES FEES.  Non-Interested Trustees are paid an annual
retainer fee of $45,000, $2,000 for each Board meeting, $1,000 for each
Committee meeting and $500 for each Valuation Subcommittee telephonic meeting
attended plus reimbursement for travel and out-of-pocket expenses. The Lead
Non-Interested Trustee is also paid an annual retainer fee of $20,000. The Audit
Committee Chairman receives an additional $2,000 for each meeting of the Audit
Committee attended and the Chairpersons of the Brokerage Committee, Operations
Committee and Performance Committee each receive an additional $1,000 for each
meeting of the Brokerage Committee, Operations Committee and Performance
Committee attended, respectively. In addition, each Non-Interested Trustee is
paid $1,000 for attending meetings of the Non-Interested Trustees held in
advance of or in connection with Board/Committee meetings. The Trust allocates
trustees fees in proportion to the net assets of the respective Funds. Thus the
Total Return Fund only pays a portion of the fees identified above.

(F) OTHER.  Fees for the cost of legal services, included in Professional fees
as shown on the Statement of Operations, provided to the Fund by the Office of
the General Counsel of NYLIM amounted to $27,471 for the year ended October 31,
2004.

The Fund pays the Manager a monthly fee for recordkeeping services provided
under the Accounting Agreement at the annual rate of 1/20 of 1% for the first
$20 million of average monthly net assets, 1/30 of 1% of the next $80 million of
average monthly net assets and 1/100 of 1% of any amount in excess of $100
million of average monthly net assets. Fees for recordkeeping services provided
to the Fund by the Manager amounted to $120,043 for the year ended October 31,
2004.

NOTE 4 -- CUSTODIAN:

State Street Bank and Trust Company is custodian of cash and securities of the
Fund. Custodial fees are charged to the Funds based on the market value of
securities in the

 30   MainStay Total Return Fund


Fund and the number of certain cash transactions incurred by the Fund.

NOTE 5 -- RESTRICTED SECURITIES:

A restricted security is a security which has been purchased through a private
offering and cannot be resold to the general public without prior registration
under the Securities Act of 1933 (the "1933 Act"). The Fund does not have the
right to demand that such securities be registered. Disposal of these securities
may involve time-consuming negotiations and expense, and prompt sale at an
acceptable price may be difficult.

Restricted securities held at October 31, 2004:

NOTE 11 -- OTHER MATTERS:

NYLIM and mutual funds that NYLIM advises have received requests for information
from various government authorities and regulatory bodies regarding market
timing, late trading, operations, fees, expenses, and other matters. NYLIM and
the funds it advises are cooperating fully in responding to these requests. As
reported in response to those requests for information, NYLIM was previously
party to agreements with certain registered representatives of broker-dealers
relating to the level of trading by clients or customers of those registered
representatives in shares of certain funds of the Trust. NYLIM is continuing to
review what effect, if any, transactions under these agreements may have had on
the funds, and will continue to apprise the Board of Trustees of such
information. NYLIM does not believe at this time that such trading had any
material effect on the funds' financial statements or their shareholders. To
date, substantially all of the costs associated with these and other regulatory
matters have been borne by NYLIM. Except as described below, neither NYLIM nor
the funds advised by it have any reason to believe that they have been targeted
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.
Discussions have been held with the SEC concerning a possible resolution of this
matter. These discussions are continuing, but there can be no assurance at this
time as to the outcome of these efforts.

NOTE 12 -- CHANGE IN INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM (UNAUDITED):

On March 8, 2004, KPMG LLP ("KPMG") was selected as the Trust's independent
auditor for the 2004 fiscal year. The selection of KPMG was recommended by the
Trust's Audit Committee, comprised of all Non-Interested Trustees, and was
approved by the Trust's Board of Trustees.

The predecessor independent auditor's reports on the Trust's financial
statements for the period ended October 31,2003 and year ended December 31, 2002
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 periods, and through, the date of engagement of KPMG, there
were no disagreements between 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 periods.

 32   MainStay Total Return Fund


REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Trustees and Shareholders of
The MainStay Funds:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of the MainStay Total Return Fund (the "Fund"),
one of the funds constituting The MainStay Funds, as of October 31, 2004, and
the related statement of operations, statement of changes in net assets and the
financial highlights for the year or period then ended. These financial
statements and financial highlights are the responsibility of the Fund's
management. Our responsibility is to express an opinion on these financial
statements and financial highlights based on our audit. The statement of changes
in net assets for the period ended October 31, 2003 and the year ended December
31, 2002, and the financial highlights for the periods presented through October
31, 2003, were audited by other auditors, whose report dated December 18, 2003
expressed an unqualified opinion thereon.

We conducted our audit in accordance with the Standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
also includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2004 by correspondence with the custodian and
brokers. As to securities purchased or sold but not yet received or delivered,
we performed other appropriate auditing procedures. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
MainStay Total Return Fund of The MainStay Funds as of October 31, 2004, the
results of its operations, the changes in its net assets and its financial
highlights for the year or period then ended, in conformity with U.S. generally
accepted accounting principles.

                    Annual Report

                    October 31, 2004


MESSAGE FROM
THE PRESIDENT

During the 12 months ended October 31, 2004, the U.S. stock market advanced, but
its pace and direction were by no means steady. Small- and mid-capitalization
stocks tended to outperform large-cap issues, and value stocks generally
outperformed growth stocks.

Economic activity, as measured by gross domestic product, increased from 4.2% in
the fourth quarter of 2003 to 4.5% in the first quarter of 2004. The pace of
economic growth slowed to 3.3% in the second quarter of 2004, and according to
preliminary estimates from the Bureau of Economic Analysis, gross domestic
product grew at a seasonally adjusted annual rate of 3.9% in the third quarter
of 2004.

Interest rates began the reporting period at a low 1.00%. In June 2004, the
Federal Open Market Committee responded to expanding output and improved labor
markets by raising the targeted federal funds rate by 25 basis points. Similar
moves in August and September brought the targeted federal funds rate to 1.75%.
In its September 2004 release, the Federal Open Market Committee affirmed its
belief that monetary policy remained accommodative.

Despite rising interest rates, bond markets generally advanced. High-yield bonds
and emerging-market debt were particularly strong. The U.S. dollar declined
relative to most other currencies, which helped U.S. exporters.

In pursuing its investment objective, each MainStay Fund consistently seeks to
apply a well-defined investment process in all market environments. We believe
that a consistent, disciplined investment approach can help investors make more
prudent and practical decisions regarding their investments.

In the report that follows, you'll find additional information about the market
forces, investment decisions, and individual securities that affected your
MainStay Fund during the 12 months ended October 31, 2004. We thank you for
investing with us, and we look forward to many years of continued service in
your behalf.

Sincerely,

/s/ GARY E. WENDLANDT
Gary E. Wendlandt
President

Performance tables and graphs do not reflect the deduction of taxes that a
shareholder would pay on distributions or Fund-share redemptions. Total returns
reflect change in share price, reinvestment of dividend and capital-gain
distributions, and maximum applicable sales charges explained in this paragraph.
The graphs assume an initial investment of $10,000 and reflect the deduction of
all sales charges that would have applied for the period of investment. Class A
shares are sold with a maximum initial sales charge of 5.5% and an annual 12b-1
fee of .25%. Class B shares are sold with no initial sales charge, are subject
to a contingent deferred sales charge (CDSC) of up to 5% if redeemed within the
first six years of purchase, and have an annual 12b-1 fee of 1.00%. Class C
shares are sold with no initial sales charge, are subject to a CDSC of 1% if
redeemed within one year of purchase, and have an annual 12b-1 fee of 1.00%.
Class I shares are sold with no initial sales charge or CDSC, have no annual
12b-1 fee, and are generally available to corporate and institutional investors
with a minimum initial investment of $5 million. Class R1 shares are sold with
no initial sales charge or CDSC and have no annual 12b-1 fee. Class R2 shares
are sold with no initial sales charge or CDSC and have an annual 12b-1 fee of
..25%. Class R1 and Class R2 shares are available only through
corporate-sponsored retirement programs, which include certain minimum program
requirements. From inception (5/1/86) through 12/31/94 (for Class A, first
offered 1/3/95), 8/31/98 (Class C, first offered 9/1/98), and 12/31/03 (Class I,
R1, and R2, first offered 1/2/04), performance of Class A, C, I, R1, and R2
shares includes the historical performance of Class B shares adjusted to reflect
the applicable sales charge (or CDSC) and fees and expenses for Class A, C, I,
R1, and R2 shares.

   performance of those Russell 1000(R) companies with lower price-to-book
   ratios and lower forecasted growth values. The Russell 1000(R) Index 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. The Russell 1000(R) Value Index is

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 data 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 Richard A. Rosen of MacKay Shields LLC

WHAT MAJOR FACTORS INFLUENCED THE STOCK MARKET DURING THE 12 MONTHS ENDED
OCTOBER 31, 2004?

An improving economy and strong growth in corporate profits drove stock prices
higher during the 12-month period. Despite three Federal Open Market Committee
increases in the targeted federal funds rate, the interest-rate and inflation
outlook remained relatively benign through most of the reporting period. In the
spring and summer of 2004, the equity markets' upward trend reversed and then
paused when investors became concerned about higher energy prices and the
unsteady pace of job growth. The ongoing risks associated with election-year
politics and geopolitical uncertainty also remained unsettling factors. Even so,
equities finished the 12-month period on a strong note, as the national
elections approached, energy prices eased somewhat, and investors appeared to
take a more positive view of stock valuations.

CAN YOU BRIEFLY DESCRIBE THE FUND'S INVESTMENT APPROACH?

The Fund normally invests at least 65% of its total assets in equity securities
and is not managed primarily to produce current income. In implementing this
strategy, the Fund normally invests in common stocks that we believe to be
"undervalued," or selling below their value, when purchased. The stocks in which
the Fund invests typically pay dividends, but the Fund may invest in
non-dividend-paying stocks if they meet the "undervalued" criterion. Normally,
the Fund invests in stocks that are listed on a national securities exchange or
are traded in the over-the-counter market. When assessing whether a stock is
undervalued, we compare the stock's market price to the company's cash flow and
interest coverage ratios, the company's book value, the estimated value of the
company's assets, the company's growth rates, and its future earnings. We may
sell stocks if we no longer believe they will contribute to meeting the
investment objective of the Fund.

WHICH SECTORS HAD THE GREATEST IMPACT ON THE FUND'S PERFORMANCE DURING THE
ANNUAL PERIOD?

Information technology and energy were the Fund's top-performing sectors
relative to the Russell 1000(R) Value Index.(1) These positive contributions,
however, were offset by mediocre individual stock performance in the financials
and health care sectors.

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

CVS rose 24% during the reporting period,(2) as sales trends in the company's
pharmacy business continued on a solid course and the company's purchase of
Eckerd stores in Texas and Florida met with investor approval.

Rising oil and gas prices helped the shares of many of the Fund's energy sector
holdings, including integrated producers ConocoPhillips (+51%), Chevron-
Texaco (+48%), and ExxonMobil (+38%). We reduced the Fund's positions in each of
these stocks by the end of the reporting period, as they approached our price
targets. Throughout the period, we also tilted the Fund's energy exposure away
from producers, which were generating high levels of free cash flow, and toward
oil services and exploration companies that we believed were likely to benefit
from increased spending. These holdings also performed well during the reporting
period, led by Transocean (+84%) and Kerr-McGee (+48%).

Holdings in the information technology and telecommunications services sectors
also contributed positively to performance. Information technology services
company Computer Sciences (+25%) benefited from strengthening trends in bookings
and increased cash-flow generation. Motorola (+29%) benefited as profitability
markedly improved in its mobile handset unit and its other business segments. We
reduced the Fund's positions in these stocks when they each neared our price
targets during the reporting period. Wireless and wireline telecommunication
services company Sprint was another strong performer, gaining 23% from the
Fund's initial purchase in June 2004 through the end of the reporting period.

HOW DID THE FUND'S FINANCIAL STOCKS FARE DURING THE REPORTING PERIOD?

The shares of most insurance companies were hurt during the reporting period by
an investigation led by the New York attorney general into insurance brokerage
practices. Among the hardest-hit companies was Marsh & McLennan, a specific
target of the New York's attorney general. From the time we

   purchases and sales, the performance of Fund holdings may differ from that of

purchased the stock in January 2004 through the end of the reporting period, the
share price was down 42%. We sold a portion of the Fund's Marsh & McLennan
position at levels well above the period-end closing price. We sold the
remainder of the position near the price at which the stock closed on October
29, 2004. Insurance provider AIG also felt the impact of the attorney general's
investigation, although AIG's shares were up 4% from the time we initiated a
position in December 2003 through the end of the Fund's fiscal year. We reduced
the Fund's position in AIG near the end of the reporting period. Despite
industry volatility, several of the Fund's other insurance-related holdings
posted strong 12-month results. The price of Allstate shares rose 25%, and the
price of Prudential Financial shares advanced 22%.

The industrials sector generally improved with the economy. Burlington Northern
Santa Fe (+47%), Boeing (+32%), and Cooper Industries (+24%) were among the
Fund's stronger holdings. As these stocks approached our price targets, we
reduced all three positions.

WHICH STOCKS DETRACTED FROM THE FUND'S RESULTS?

Several pharmaceutical holdings were weak, including Merck (-27%) which fell
when its popular drug Vioxx was recalled. We reduced the Fund's position in
Merck at levels above the period-end closing price, but we continued to hold a
position in this stock, as we believed the shares to be near the bottom of their
historical valuation range. Shares of pharmaceutical competitor Pfizer (-7%)
fell from our August 2004 purchase price through the end of the period, and we
reduced the Fund's position in this stock as well.

Navistar (-15%), a truck manufacturer, was an exception to the positive trend in
the industrials sector. After posting strong gains in 2003, Navistar saw its
share price decline throughout much of the reporting period. Fortunately, we
reduced the Fund's position at levels above the end-of-period closing price.

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

As of October 31, 2004, the Fund had overweighted positions relative to the
Russell 1000(R) Value Index in consumer staples, energy, health care,
industrials, materials, and information technology. As of the same date, the
Fund was underweighted relative to the Index in consumer discretionary,
financials, and utilities.

WHAT DO YOU ANTICIPATE GOING FORWARD?

We intend to continue to emphasize stocks with better-than-market visibility for
earnings and cash-flow generation, as well as stocks with well-below-market
valuations. At the end of the period, we were finding many stocks with these
characteristics in the energy, consumer staples, and information technology
sectors, but were finding few similar opportunities in the utilities and
consumer discretionary sectors.

We expect energy prices to remain at relatively high levels, which may spur
increased exploration and production activity and benefit oil-drilling
companies. We have also added to the Fund's holdings in the information
technology and consumer staples sectors, as cash-flow generation prospects have
improved for many of these companies. Many health care stocks have struggled in
2004 because of political and company-specific concerns. Since we see an
emerging theme in this sector, we may add to the Fund's health care holdings as
opportunities arise.

We intend to remain underweighted in areas of the market that depend on consumer
spending, based on questions about where incremental increases might be
generated. We have focused our concerns on the consumer discretionary sector and
some financial institutions. Despite a strong showing in 2004, utilities appear
to offer little value going forward, and we intend to maintain the Fund's
underweighted position in this sector. We remain confident in our disciplined
classic value strategy and will continue to seek opportunities among undervalued
stocks with improving fundamental characteristics.

NOTES TO FINANCIAL STATEMENTS

NOTE 1 -- ORGANIZATION AND BUSINESS:

The MainStay Funds (the "Trust") was organized on January 9, 1986 as a
Massachusetts business trust. The Trust is registered under the Investment
Company Act of 1940, as amended (the "1940 Act"), as an open-end management
investment company and comprises twenty-two funds (collectively referred to as
the "Funds"). These financial statements and notes relate only to MainStay Value
Fund (the "Fund"), a diversified fund.

The Fund currently offers six classes of shares, Class A shares, Class B shares,
Class C shares, Class I shares, Class R1 shares and Class R2 shares. Class A
shares, whose distribution commenced on January 3, 1995, 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 within one year of purchase
of Class C shares. Class I, Class R1 and Class R2 shares are not subject to
sales charge. Distribution of Class B shares and Class C shares commenced on May
1, 1986 and September 1, 1998, respectively.

Distribution of Class I shares, Class R1 shares and Class R2 shares commenced on
January 2, 2004. The six classes of shares bear the same voting (except for
issues that relate solely to one class), dividend, liquidation and other rights
and conditions except that Class B shares and Class C shares are subject to
higher distribution fee rates than Class A shares and Class R2 shares under a
distribution plan pursuant to Rule 12b-1 under the 1940 Act. Class I shares and
Class R1 shares are not subject to a distribution or service fee. Class R1 and
Class R2 shares are authorized to pay to New York Life Investment Management
LLC, its affiliates, or independent third-party service providers, as
compensation for services rendered to shareholders of Class R1 or Class R2
shares, a shareholder service fee.

The Fund's investment objective is to realize maximum long-term total return
from a combination of capital growth and income.

NOTE 2 -- SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with generally accepted
accounting principles and follows the significant accounting policies described
below.

(A) SECURITIES VALUATION.  Equity securities are valued at the latest quoted
sales prices as of the close of 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. Options contracts are valued at the last posted settlement price on the
market where any such options 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. Securities for which market
quotations are not readily available are valued by methods deemed by the Board
of Trustees to represent fair value. Reasons for which securities may be valued
in this manner include, but are not limited to, trading for a security has been
halted or suspended, a security has been de-listed from a national exchange, or
trading on a security's primary market is temporarily closed at a time when
under normal conditions it would be open. The Fund did not hold securities at
October 31, 2004, that were valued in such manner.

(B) SECURITIES LENDING.  The 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.)

(C) PURCHASED AND WRITTEN OPTIONS.  The Fund may write covered call and put
options on its 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, the Fund forgoes in exchange for the premium 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, the
Fund, in exchange for the premium, accepts the risk of a decline in the market
value of the underlying security or foreign currency below the exercise price. A
call option may be covered by the call writer's owning the underlying security
throughout the option period. A call option may

 16   MainStay Value Fund


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.

The Fund may purchase call and put options on its portfolio securities. The Fund
may purchase call options to protect against an increase in the price of the
security it anticipates purchasing. The Fund may purchase put options on its
securities to protect against a decline in the value of the security or to close
out covered written put positions. The Fund may also purchase options to seek to
enhance returns. Risks may arise from an imperfect correlation between the
change in market value of the securities held by the Fund and the prices of
options relating to the securities 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.

(D) FEDERAL INCOME TAXES.  The Fund's policy is to comply with the requirements
of the Internal Revenue Code applicable to regulated investment companies and to
distribute all of its taxable income to the shareholders of the Fund within the
allowable time limits. Therefore, no federal income or excise tax provision is
required. Investment income received by the Fund from foreign sources may be
subject to foreign income taxes. These foreign income taxes are withheld at the
source.

(E) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are
recorded on the ex-dividend date. The Fund intends to declare and pay any
dividends quarterly and capital gain distributions, if any, annually. 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.

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

(G) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred except where direct allocations of expenses can be made. Expenses
(other than expenses incurred under the distribution plans) are allocated to
separate classes of shares based upon their relative net asset value on the date
the expenses are incurred. The expenses borne by the Fund, including those of
related parties to the Fund, are shown in the Statement of Operations.

(H) 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.

NOTE 3 -- FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER AND SUBADVISOR.  New York Life Investment Management LLC ("NYLIM" or
the "Manager"), an indirect wholly-owned subsidiary of New York Life Insurance
Company ("New York Life"), serves as the Fund's manager. The Manager provides
offices, conducts clerical, recordkeeping and bookkeeping services, and keeps
the financial and accounting records required for the Fund. The Manager also
pays the salaries and expenses of all personnel affiliated with the Fund and all
the operational expenses that are not the responsibility of the Fund. MacKay
Shields LLC (the "Subadvisor"), a registered investment advisor and indirect
wholly-owned subsidiary of New York Life, is responsible for the day-to-day
portfolio management of the Fund.

The Trust, on behalf of the Fund, paid the Manager a monthly fee for services
performed and the facilities furnished at an annual rate of 0.72% of the Fund's
average daily net assets on assets up to $200 million, 0.65% on assets from $200
million to $500 million and 0.50% on assets in excess of $500 million. Effective
December 1, 2004, NYLIM has voluntarily agreed to reimburse the expenses of the
Fund to the extent that operating expenses would exceed on an annualized basis
1.22%, 1.97% and 1.97% of the average daily net assets of the Class A, Class B
and Class C shares, respectively, and an equivalent reduction in the management
fee for Class I, Class R1 and Class R2 shares. For the year ended October 31,
2004, the Manager earned from the Fund $4,420,269.

Pursuant to the terms of a Sub-Advisory Agreement between NYLIM and MacKay
Shields, the Manager pays the Subadvisor a monthly fee at an annual rate of
0.36% of the Fund's average daily net assets up to $200 million, 0.325% on
assets from $200 million to $500 million and 0.25% on assets in excess of $500
million. To the extent the Manager has agreed to reimburse expenses of the

                                                    www.mainstayfunds.com     17

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

Fund, the Subadvisor has voluntarily agreed to do so proportionately.

(B) DISTRIBUTION AND SERVICE FEES.  The Trust, on behalf of the Fund, has a
Distribution Agreement with NYLIFE Distributors LLC (the "Distributor"), an
indirect wholly-owned subsidiary of New York Life. The Fund, with respect to
Class A, Class B, Class C and Class R2 shares, has adopted distribution plans
(the "Plans") in accordance with the provisions of Rule 12b-1 under the 1940
Act. Pursuant to the Class A and Class R2 Plan, the Distributor receives a
monthly fee from the Fund at an annual rate of 0.25% of the average daily net
assets of the Fund's Class A and Class R2 shares, which is an expense of the
Class A and Class R2 shares of the Fund for distribution or service activities
as designated by the Distributor. Pursuant to the Class B and Class C Plans, the
Fund pays the Distributor a monthly fee, which is an expense of the Class B and
Class C shares of the Fund, at the annual rate of 0.75% of the average daily net
assets of the Fund's Class B and Class C shares. The Distribution Plans provide
that the Class B and Class C shares of the Fund 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 Fund. Class I shares are not subject to a distribution or
service fee.

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

The Fund has adopted a shareholder services plan with respect to Class R1 and
Class R2 shares. Under the terms of this plan, Class R1 and Class R2 shares are
authorized to pay to NYLIM, its affiliates, or independent third-party
providers, as compensation for services rendered, a shareholder services fee at
the rate of 0.10% of the average daily net assets of the Fund's Class R1 and R2
shares.

(C) SALES CHARGES.  The Fund was advised by the Distributor that the amount of
sales charges retained on sales of Class A shares was $39,067 for the year ended
October 31, 2004. The Fund was also advised that the Distributor retained
contingent deferred sales charges on redemptions of Class A, Class B and Class C
shares of $11,896, $249,437 and $1,243, respectively, for the year ended October
31, 2004.

(D) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT.  NYLIM
Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's
transfer, dividend disbursing and shareholder servicing agent. NYLIM Service has
entered into an agreement with Boston Financial Data Services ("BFDS") pursuant
to which BFDS will perform certain of the services for which NYLIM Service is
responsible. Transfer agent expenses for the year ended October 31, 2004,
amounted to $2,392,111.

(E) NON-INTERESTED TRUSTEES.  Non-Interested Trustees are paid an annual
retainer fee of $45,000, $2,000 for each Board meeting, $1,000 for each
Committee meeting and $500 for each Valuation Subcommittee telephonic meeting
attended plus reimbursement for travel and out-of-pocket expenses. The Lead
Non-Interested Trustee is also paid an annual retainer fee of $20,000. The Audit
Committee Chairman receives an additional $2,000 for each meeting of the Audit
Committee attended and the Chairpersons of the Brokerage Committee, Operations
Committee and Performance Committee each receive an additional $1,000 for each
meeting of the Brokerage Committee, Operations Committee and Performance
Committee attended, respectively. In addition, each Non-Interested Trustee is
paid $1,000 for attending meetings of the Non-Interested Trustees held in
advance of or in connection with Board/Committee meetings. The Trust allocates
trustees fees in proportion to the net assets of the respective Funds. Thus the
Value Fund only pays a portion of the fees identified above.

(F) OTHER.  Fees for the cost of legal services, included in Professional fees
as shown on the Statement of Operations, provided to the Fund by the Office of
the General Counsel of NYLIM amounted to $21,193 for the year ended October 31,
2004.

The Fund pays the Manager a monthly fee for recordkeeping services provided
under the Accounting Agreement at the annual rate of 1/20 of 1% for the first
$20 million of average monthly net assets, 1/30 of 1% of the next $80 million of
average monthly net assets and 1/100 of 1% of any amount in excess of $100
million of average monthly net assets. Fees for recordkeeping services provided
to the Fund by the Manager amounted to $97,270 for the year ended October 31,
2004.

NOTE 4 -- CUSTODIAN:

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

NOTE 5 -- FEDERAL INCOME TAX:

As of October 31, 2004, the components of accumulated gain on a tax basis were
as follows:

<Table>
<Caption>
ORDINARY   ACCUMULATED CAPITAL    UNREALIZED    TOTAL ACCUMULATED
 INCOME     AND OTHER LOSSES     APPRECIATION         GAIN
                                       

$737,736     $(38,153,526)       $69,112,153       $31,696,363
</Table>

The difference between book-basis and tax-basis unrealized appreciation is
primarily due to wash sale deferrals.

At October 31, 2004, for federal income tax purposes, capital loss carryforwards
of $38,153,526 were available as shown in the table below, to the extent
provided by the regulations to offset future realized gains of the Fund

 18   MainStay Value 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.

amount, regardless of usage, to The Bank of New York, which acts as agent to the
syndicate. Such commitment fees are allocated among the funds based upon net
assets and other factors. Interest on any revolving credit loan is charged based

NOTE 10 -- OTHER MATTERS:

NYLIM and mutual funds that NYLIM advises have received requests for information
from various government authorities and regulatory bodies regarding market
timing, late trading, operations, fees, expenses, and other matters. NYLIM and
the funds it advises are cooperating fully in responding to these requests. As
reported in response to those requests for information, NYLIM was previously
party to agreements with certain registered representatives of broker-dealers
relating to the level of trading by clients or customers of those registered
representatives in shares of certain funds of the Trust. NYLIM is continuing to
review what effect, if any, transactions under these agreements may have had on
the funds, and will continue to apprise the Board of Trustees of such
information. NYLIM does not believe at this time that such trading had any
material effect on the funds' financial statements or their shareholders. To
date, substantially all of the costs associated with these and other regulatory
matters have been borne by NYLIM. Except as described below, neither NYLIM nor
the funds advised by it have any reason to believe that they have been targeted
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.
Discussions have been held with the SEC concerning a possible resolution of this
matter. These discussions are continuing, but there can be no assurance at this
time as to the outcome of these efforts.

NOTE 11 -- CHANGE IN INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM (UNAUDITED):

On March 8, 2004, KPMG LLP ("KPMG") was selected as the Trust's independent
auditor for the 2004 fiscal year. The selection of KPMG was recommended by the
Trust's Audit Committee, comprised of all Non-Interested Trustees, and was
approved by the Trust's Board of Trustees.

The predecessor independent auditor's reports on the Trust's financial
statements for the period ended October 31, 2003 and year ended December 31,
2002 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 periods, and through the date of engagement of KPMG, there
were no disagreements between 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 periods.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Trustees and Shareholders of
The MainStay Funds:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of the MainStay Value Fund (the "Fund"), one of
the funds constituting The MainStay Funds, as of October 31, 2004, and the
related statement of operations, statement of changes in net assets and the
financial highlights for the year or period then ended. These financial
statements and financial highlights are the responsibility of the Fund's
management. Our responsibility is to express an opinion on these financial
statements and financial highlights based on our audit. The statement of changes
in net assets for the period ended October 31, 2003 and the year ended December
31, 2002, and the financial highlights for the periods presented through October
31, 2003, were audited by other auditors, whose report dated December 18, 2003
expressed an unqualified opinion thereon.

We conducted our audit in accordance with the Standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
also includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2004 by correspondence with the custodian and
brokers. As to securities purchased or sold but not yet received or delivered,
we performed other appropriate auditing procedures. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
MainStay Value Fund of The MainStay Funds as of October 31, 2004, the results of
its operations, the changes in its net assets and its financial highlights for
the year or period then ended, in conformity with U.S. generally accepted
accounting principles.

                    Annual Report

                    October 31, 2004


MESSAGE FROM
THE PRESIDENT

During the 12 months ended October 31, 2004, the U.S. stock market advanced, but
its pace and direction were by no means steady. Small- and mid-capitalization
stocks tended to outperform large-cap issues, and value stocks generally
outperformed growth stocks.

Economic activity, as measured by gross domestic product, increased from 4.2% in
the fourth quarter of 2003 to 4.5% in the first quarter of 2004. The pace of
economic growth slowed to 3.3% in the second quar-
ter of 2004, and according to preliminary estimates from the Bureau of Economic
Analysis, gross domestic product grew at a seasonally adjusted annual rate of
3.9% in the third quarter of 2004.

Interest rates began the reporting period at a low 1.00%. In June 2004, the
Federal Open Market Committee responded to expanding output and improved labor
markets by raising the targeted federal funds rate by 25 basis points. Similar
moves in August and September brought the targeted federal funds rate to 1.75%.
In its September 2004 release, the Federal Open Market Committee affirmed its
belief that monetary policy remained accommodative.

Despite rising interest rates, bond markets generally advanced. High-yield bonds
and emerging-market debt were particularly strong. The U.S. dollar declined
relative to most other currencies, which helped U.S. exporters.

In pursuing its investment objective, each MainStay Fund consistently seeks to
apply a well-defined investment process in all market environments. We believe
that a consistent, disciplined investment approach can help investors make more
prudent and practical decisions regarding their investments.

In the report that follows, you'll find additional information about the market
forces, investment decisions, and individual securities that affected your
MainStay Fund during the 12 months ended October 31, 2004. We thank you for
investing with us, and we look forward to many years of continued service in
your behalf.
Sincerely,
/s/ GARY E. WENDLANDT

Gary E. Wendlandt

President

Performance tables and graphs do not reflect the deduction of taxes that a
shareholder would pay on distributions or Fund-share redemptions. Total returns
reflect change in share price, reinvestment of dividend and capital-gain
distributions, and maximum applicable sales charges explained in this paragraph.
The graphs assume an initial investment of $10,000 and reflect the deduction of
all sales charges that would have applied for the period of investment. Class A
shares are sold with a maximum initial sales charge of 4.5% and an annual 12b-1
fee of .25%. Class B shares are sold with no initial sales charge, are subject
to a contingent deferred sales charge (CDSC) of up to 5% if redeemed within the
first six years of purchase, and have an annual 12b-1 fee of 1.00%. Class C
shares are sold with no initial sales charge, are subject to a CDSC of 1% if
redeemed within one year of purchase, and have an annual 12b-1 fee of 1.00%.
Class I shares are sold with no initial sales charge or CDSC, have no annual
12b-1 fee, and are generally available to corporate and institutional investors
with a minimum initial investment of $5 million. From inception (2/28/97)
through 8/31/98, performance for Class C shares (first offered 9/1/98), includes
the historical performance of Class B shares adjusted to reflect the applicable
CDSC for Class C shares. From inception (2/28/97) through 12/31/03, performance
for Class I shares (first offered 1/2/04) includes the historical performance of
Class A shares adjusted to reflect the applicable fees and expenses for Class I
shares.

1. The Fund compares itself to a Three-Index Composite that assumes equal
   investments in the Lehman Brothers(R) Aggregate Bond Index, the Credit Suisse
   First Boston(TM) High Yield Index, and the Citigroup Non-U.S. Dollar World
   Government Bond Index. All indices are unmanaged. The indices measure the
   performance of securities in the U.S. government and domestic
   investment-grade bond sector, the U.S. high-yield bond sector, and the
   international bond sector, respectively. Results assume that all income and
   capital gains are reinvested in the index or indices that produce them. The
   Fund's Three-Index Composite is considered to be the Fund's broad-based
   securities-market index for comparison purposes. An investment cannot be made
   directly into an index or this composite.
2. The Lehman Brothers(R) Aggregate Bond Index is an unmanaged index that
   includes the following other unmanaged Lehman Brothers(R) Indices: the
   Government Index, the Corporate Index, the Mortgage-Backed Securities Index
   and the Asset-Backed Securities Index. To qualify for inclusion in the Lehman
   Brothers(R) Aggregate Bond Index, securities must be U.S. dollar denominated
   and investment grade and have a fixed-rate coupon, a remaining maturity of at
   least one year, and a par amount outstanding of at least $150 million.
   Results assume reinvestment of all income and capital-gains. An investment
   cannot be made directly into an index.
3. Lipper Inc. is an independent fund performance monitor. Results are based on
   total returns with all dividend and capital-gain distributions reinvested.

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

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 data 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 Donald E. Morgan and Joseph Portera of
MacKay Shields LLC

CAN YOU BRIEFLY DESCRIBE THE FUND'S INVESTMENT APPROACH?

The Fund normally invests at least 65% of its total assets in a diversified
portfolio of domestic and foreign debt or debt-related securities issued by
government and corporate issuers. The securities may be denominated in U.S. or
foreign currencies and may have fixed, variable, floating, or inverse-floating
rates of interest. The Fund invests in various bond market sectors (U.S.
government--including mortgage-related and asset-backed--securities, foreign
government, U.S. corporate and foreign corporate, including high-yield
securities in each of the sectors). Allocations across market sectors are based
on current and projected economic and market conditions. In implementing this
strategy, we seek to identify investment opportunities based on the financial
condition and competitiveness of individual companies. In making allocation and
sector decisions, we may rely on fundamental economic cycle analysis. We may
also consider credit quality and interest-rate trends. Investments may include
bonds of established economies and emerging markets.

HOW DID YOU POSITION THE FUND DURING THE 12 MONTHS ENDED OCTOBER 31, 2004?

We tend to take a long-term view of asset allocation and try to avoid shifting
in and out of the broader sectors. During the reporting period, we maintained a
static weighting of 33% in high-grade securities, 39% in high-yield bonds, and
28% in international debt.

HOW DID THE FUND PERFORM RELATIVE TO ITS BENCHMARK AND PEERS?

Despite the massive rally in high-yield securities, we elected to maintain only
a modestly overweighted position in high-yield bonds, since the benchmark
equally weights the three principal sectors in which the Fund invests. During
the reporting period, the Fund underperformed its peers for reasons that were
difficult to pinpoint in light of the market's many undercurrents. The average
peer fund may have held more high-yield debt or may have had broader exposure to
foreign currencies or emerging-market dollar debt. Our prudent
currency-management strategy gave the Fund at most a 12% exposure to foreign
exchange fluctuations. During the reporting period, however, the U.S. dollar
weakened, and more than half of the Citigroup(R) Non-U.S. Dollar Bond Index's(1)
12.2% return in U.S. dollars was attributable to currency movements.

HIGH-GRADE DOMESTIC BONDS

WHAT ECONOMIC FACTORS INFLUENCED THE HIGH-GRADE BOND MARKET DURING THE 12 MONTHS
ENDED OCTOBER 31, 2004?

The Federal Reserve maintained the targeted federal funds rate at an
accommodative 1.00% through the first half of the Fund's fiscal year, and from
November 2003 through March 2004, economic data was mixed. In April 2004,
however, uniformly firm economic releases challenged the assumption that there
was little risk of the economy overheating. Many investors began to believe the
Federal Reserve's cautionary stance would be relatively short-lived. Consistent
with market expectations, the Federal Open Market Committee tightened monetary
policy at its June 30, 2004, meeting by raising the targeted federal funds rate
to 1.25%. Another 25-basis-point rate hike followed in August, and yet another
in September. These moves brought the targeted federal funds rate to 1.75% at
the end of October 2004.

HOW DID THESE FACTORS AFFECT TREASURY YIELDS?

During the 12-month reporting period, the U.S. Treasury yield curve pivoted
around the five-year maturity benchmark. Two-year Treasury yields rose from 1.8%
to 2.6%; five-year yields were basically unchanged at 3.25%; 10-year yields fell
from 4.3% to 4.0%; and 30-year yields declined from 5.1% to 4.8%. The narrowing
of the yield spread between the two-year and 30-year maturities (commonly known
as a flattening of the yield curve) was prompted by Federal Reserve tightening,
lower inflation expectations, and large block purchases of U.S. Treasury
securities by foreign governments.

Funds that invest in bonds are subject to interest rate, credit, and inflation
risk and can lose principal when interest rates rise. 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. High-yield securities ("junk bonds") are
generally considered speculative because they present a greater risk of loss
than higher-quality debt securities and may be subject to greater price
volatility. 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.

   World Government Bond Index.

 6   MainStay Diversified Income Fund


HOW DID YOU POSITION THE HIGH-GRADE PORTION OF THE FUND'S PORTFOLIO AMONG THE
VARIOUS BOND SECTORS?

The Fund's high-grade position in credit-related securities contributed
positively to the Fund's performance. High-grade positions in mortgage-backed
and asset-backed securities, which tend to perform well when U.S. Treasuries are
range bound, also had a positive impact. As of October 31, 2004, the high-grade
portion of the Fund's portfolio was diversified across U.S. Treasuries, agency
debentures, investment-grade corporates, residential mortgage-backed securities,
commercial mortgage-backed securities, and asset-backed securities.

HOW DID YIELD-CURVE AND DURATION POSITIONING AFFECT PERFORMANCE IN THE
HIGH-GRADE PORTION OF THE FUND'S PORTFOLIO?

We maintained a neutral yield-curve posture during the 12-month reporting
period, so the flattening of the yield curve had minimal impact on the Fund's
performance. Our duration positioning, however, detracted from relative
performance. We maintained a modestly shorter-than-benchmark duration for much
of the reporting period, as intermediate- and long-term Treasury yields rallied.
We had decided to shorten the Fund's duration early in the Fund's fiscal year,
anticipating that the unusually low average yield of the U.S. Treasury sector
was unsustainable. What we failed to appreciate was the sizeable impact of a
weaker U.S. dollar on interest rates. Specifically, foreign central banks bought
large blocks of U.S. Treasuries to stall the appreciation of their currencies
against the weaker U.S. dollar.

HIGH-YIELD BONDS

HOW DID YOU POSITION THE HIGH-YIELD PORTION OF THE FUND'S PORTFOLIO DURING THE
12-MONTH REPORTING PERIOD?

As the high-yield bond market continued to climb, the Fund continued to benefit
from our careful bottom-up security selection. Over the 12 months ended October
31, 2004, we reduced exposure to high-yield securities in the utilities,
wireless communications, telecommunications, information technology, and
food/tobacco sectors. We increased high-yield weightings among companies in
services and chemicals. At the end of October 2004, the high-yield portion of
the Fund's portfolio was overweighted relative to the Credit Suisse First
Boston(TM) High Yield Index(2) in broadcasting, cable/wireless, and airlines. At
the same time, the Fund was underweighted relative to the Index in gaming,
manufacturing, and food & drugs. As issuers sought to refinance while interest
rates were still low, several of the Fund's high-yield holdings tendered.

WHAT WERE SOME OF THE FUND'S STRONG HIGH-YIELD HOLDINGS DURING THE REPORTING
PERIOD?

The Fund's metal-related bonds--such as AK Steel, Algoma Steel, and Allegheny
Ludlum--were among the top performers for the last 12 months as commodity prices
strengthened and North American manufacturing activity increased. Cable
companies, including FrontierVision and UGC Europe, were also strong high-yield
performers for the reporting period. In December 2003, UnitedGlobalCom acquired
all shares of the recently reorganized UGC Europe. These companies were among
several cable providers that reported good earnings over the annual period. The
performance of these companies led to upbeat expectations for the industry as a
whole.

WERE THERE OTHER AREAS OF STRENGTH IN THE HIGH-YIELD PORTION OF THE FUND'S
PORTFOLIO?

Several of the Fund's wireless companies performed well over the 12-month
reporting period. US Unwired, Alamosa, Nextel International, and Mobifon each
outperformed related securities in the CSFB High Yield Index. The Fund's
holdings in Nextel International consisted of equity received as the result of a
restructuring at the beginning of 2003.

WERE THERE ANY HIGH-YIELD HOLDINGS THAT DIDN'T MEET YOUR EXPECTATIONS?

The Fund's high-yield investments in the airline industry had disappointing
performance, as airline costs rose with the rising price of oil. Concerns about
a possible bankruptcy at Delta Airlines affected our position in the company.
Delta sought a resolution with the pilots' union that didn't arrive until the
end of October 2004. Delta Airlines and Northwest Airlines were among the Fund's
poorest high-yield performers during the reporting period. Other high-yield
holdings that produced disappointing results were securities issued by utilities
company Calpine, restaurant company Family Restaurants, and cutting-and
welding-products company Thermadyne Holdings.

INTERNATIONAL BONDS

WHAT MAJOR FACTORS INFLUENCED THE INTERNATIONAL BOND MARKETS DURING THE 12
MONTHS ENDED OCTOBER 31, 2004?

In the early part of the reporting period, geopolitical risks buoyed government
bond markets. Few investors believed that the global economy was growing fast
enough to warrant higher interest rates soon. With improving economic data from
the United States, Japan, and China, however, rising rates became inevitable.
Indeed, for most of the period, the United Kingdom and Australian monetary
authorities were aggressively raising short-term interest rates.

HOW DID VARIOUS INTERNATIONAL-BOND MARKETS PERFORM?

Among developed international markets, the best performer was Norway, which
returned more than 8% in local currency terms for the 12-month reporting period.
The U.K., Canada, Australia, and Sweden each had 12-month returns better than 7%
in local currency terms. The worst performer was Japan, which was up only 1.5%
in local currency terms for the reporting period.

WHAT EFFECT DID CURRENCY POSITIONING HAVE ON THE INTERNATIONAL-BOND PORTION OF
THE FUND'S PORTFOLIO DURING THE REPORTING PERIOD?

Currency positioning was a major detractor from performance in the international
bond portion of the Fund's portfolio. During the reporting period, nearly every
major foreign currency rallied relative to the U.S. dollar. Unfortunately
defensive currency management and fundamental analysis led us to underweight
foreign currency in the portfolio, specifically but not solely in the Japanese
yen.

WHAT INFLUENCE DID COUNTRY ALLOCATION HAVE ON FUND PERFORMANCE?

Over the period, we made significant asset shifts among international-bond
markets, based primarily on interest-rate and currency-movement expectations. We
reduced exposure to Canadian dollar bonds. We redeployed some of those assets
into U.K. bonds and increased duration within the U.K. market significantly. We
also increased the Fund's exposure in core European bonds. Within the
Scandinavian markets, we increased exposure in Danish krone denominated bonds
and established a position in Norway, seeking to benefit from advances in the
oil sector. We believed that the Norwegian krone would likely outperform the
euro as oil prices continued to rise--and it did. Shifting the portfolio's
duration risk away from Canada and into markets that we believed would
outperform in a rising U.S. interest-rate environment proved effective, making a
positive contribution to the Fund's results. We also increased the Fund's
exposure to Japan during the reporting period. With Japanese short-term rates
close to zero, however, we focused on investments in corporate and emerging
names rather than on government bonds.

HOW DID EMERGING-MARKET DEBT PERFORM?

The Fund's holdings in emerging-market debt performed well over the 12-month
reporting period, despite higher U.S. interest rates. There was a sell-off in
the emerging-market sector during the second quarter of 2004, but
emerging-market debt subsequently recovered and posted impressive returns, as
yield spreads to U.S. Treasuries narrowed. We maintained about 12% of the Fund's
international-bond assets in emerging-market debt.

WHAT IS YOUR OUTLOOK FOR FUND?

Going forward, it appears that investors still have sufficient appetite for risk
to favor high-yielding assets. The Federal Reserve will no doubt continue to
raise the targeted federal funds rate slowly. As a result, we see value in
non-U.S. dollar denominated debt in markets where we believe interest-rate
tightening is unlikely. Continental Europe and the U.K. offer the best potential
to outperform U.S. Treasuries. We will continue to actively manage within each
subsector as well as the Fund's overall asset allocation as we seek to maximize
returns and minimize risks--especially credit and currency risks in the
higher-yielding portions of the Fund's portfolio.

NOTES TO FINANCIAL STATEMENTS

NOTE 1 -- ORGANIZATION AND BUSINESS:

The MainStay Funds (the "Trust") was organized on January 9, 1986 as a
Massachusetts business trust. The Trust is registered under the Investment
Company Act of 1940, as amended (the "1940 Act"), as an open-end management
investment company and comprises twenty-two funds (collectively referred to as
the "Funds"). These financial statements and notes relate only to MainStay
Diversified Income Fund (the "Fund"), a diversified fund.

The Fund currently offers four classes of shares. Distribution of Class A shares
and Class B shares commenced on February 28, 1997. Class C shares and Class I
shares were initially offered on September 1, 1998 and January 2, 2004,
respectively. 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 within one year of purchase of Class C shares. Class I shares are
not subject to sales charge. Class A shares, Class B shares, Class C shares and
Class I shares bear the same voting (except for issues that relate solely to one
class), dividend, liquidation and other rights and conditions. Each class of
shares other than Class I shares bears distribution and/or service fee payments
under a distribution plan pursuant to Rule 12b-1 under the 1940 Act. Class I
shares are not subject to a distribution or service fee.

The Fund's objective is to provide current income and competitive overall return
by investing primarily in domestic and foreign debt securities.

The Fund also invests in high yield securities (sometimes called "junk bonds"),
which are generally considered speculative because they present a greater risk
of loss, including default, than higher quality debt securities. These
securities pay a premium -- a high interest rate or yield -- because of the
increased risk of loss. These securities can also be subject to a greater price
volatility.

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

Effective January 1, 2004, the Fund changed its name to MainStay Diversified
Income Fund from MainStay Strategic Income Fund.

NOTE 2 -- SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with generally accepted
accounting principles and follows the significant accounting policies described
below.

(A) SECURITIES VALUATION.  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 New York Stock Exchange
(generally 4:00 p.m. Eastern time.) Equity securities are valued at the latest
quoted sales prices as of the close of trading on the Exchange 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. Options contracts are valued at the last sale
price on the market where such options are principally traded. Foreign currency
forward contracts are valued at their fair market values determined on the basis
of the mean between the last current bid and asked prices based on dealer or
exchange quotations. 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. Securities for which market quotations are not
readily available are valued by methods deemed by the Board of Trustees to
represent fair value. Reasons for which securities may be valued in this manner
include, but are not limited to, trading for a security has been halted or
suspended, a security has been de-listed from a national exchange, or trading on
a security's primary market is temporarily closed at a time when under normal
conditions it would be open. The total value of securities that were valued in
such manner amounted to $162,313 at October 31, 2004.

Certain events may occur between the time that foreign markets close, on which
securities held by the Fund principally trade, and the time at which the Fund's
NAV is calculated. These events may include, but are not limited to, situations
relating to a single issue in a market sector, significant fluctuations in U.S.
or foreign markets, natural disasters, armed conflicts, governmental actions or
other developments not tied directly to the securities markets. Should the
Manager or Subadvisor conclude that such events may have affected the accuracy
of the last price reported on the local foreign market, the Manager or
Subadvisor may, pursuant to procedures adopted by the Fund, adjust the value of
the local price to reflect the impact on the price of such securities as a
result of such events.

(B) FOREIGN CURRENCY FORWARD CONTRACTS.  A foreign currency forward contract is
an agreement to buy or sell currencies of different countries on a specified
future date at a specified rate. During the period the forward contract is open,
changes in the value of the contract are recognized as unrealized gains or
losses by "marking to

 30   MainStay Diversified Income Fund


market" such contract on a daily basis to reflect the market value of the
contract at the end of each day's trading. When the forward contract is closed,
the Fund records a realized gain or loss equal to the difference between the
proceeds from (or cost of) the closing transaction and the Fund's basis in the
contract. The Fund may enter into foreign currency forward contracts primarily
to hedge its foreign currency denominated investments and receivables and
payables against adverse movements in future foreign exchange rates or to try to
enhance the Fund's returns.

The use of foreign currency forward contracts involves, to varying degrees,
elements of market risk in excess of the amount recognized in the Statement of
Assets and Liabilities. The contract amount reflects the extent of the Fund's
involvement in these financial instruments. Risks arise from the possible
movements in the foreign exchange rates underlying these instruments. The
unrealized appreciation on forward contracts reflects the Fund's exposure at
period end to credit loss in the event of a counterparty's failure to perform
its obligations.

(C) PURCHASED AND WRITTEN OPTIONS.  The Fund may write covered call and put
options on its 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 cancelled in closing purchase
transactions are added to the proceeds or netted against the amount paid on the
transaction to determine the realized gain or loss. By writing a covered call
option, a Fund foregoes in exchange for the premium 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.

The Fund may purchase call and put options on its portfolio securities or
foreign currencies. The Fund may purchase call options to protect against an
increase in the price of the security or foreign currency it anticipates
purchasing. The Fund may purchase put options on its securities or foreign
currencies to protect against a decline in the value of the security or foreign
currency or to close out covered written put positions. The Fund may also
purchase options to seek to enhance returns. Risks may arise from an imperfect
correlation between the change in market value of the securities or foreign
currencies held by the Fund and the prices of options relating to the securities
or foreign currencies purchased or sold by the Fund and from the possible lack
of a liquid secondary market for an option. The maximum exposure to loss for any
purchased option is limited to the premium initially paid for the option.

(D) LOAN ASSIGNMENTS, PARTICIPATIONS AND COMMITMENTS.  The Fund invests in loan
assignments and loan participations. Loan assignments and participations are
agreements to make money available (a "commitment") to a borrower in a specified
amount, at a specified rate and within a specified time. Such loan assignments
and participations are typically senior, secured and collateralized in nature.
The Fund records an investment when the borrower withdraws money and records
interest as earned. These loans pay interest at rates which are periodically
reset by reference to a base lending rate plus a spread. These base lending
rates are generally the prime rate offered by a designated U.S. bank or London
InterBank Offered Rate (LIBOR).

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

The Fund assumes the credit risk of the Borrower, the Selling Participant and
any other persons interpositioned between the Fund and the Borrower
("Intermediate Participants"). In the event that the Borrower, Selling
Participant or Intermediate Participants becomes insolvent or enters into
bankruptcy, the Fund may incur certain costs and delays in realizing payment, or
may suffer a loss of principal and/or interest.

Unfunded commitments represent the remaining obligation of the Fund to the
Borrower. At any point in time, up to the maturity date of the issue, the
Borrower may demand the unfunded portion. These unfunded amounts are recorded in
memorandum accounts. (See Note 7).

(E) SECURITIES LENDING.  The 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 9).

(F) MORTGAGE DOLLAR ROLLS.  The Fund enters into mortgage dollar roll ("MDR")
transactions in which it sells mortgage-backed securities ("MBS") from its
portfolio to a counterparty from whom it simultaneously agrees to buy a similar
security on a delayed delivery basis. The MDR

                                                    www.mainstayfunds.com     31

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

transactions of the Fund are classified as purchase and sale transactions. The
securities sold in connection with the MDRs are removed from the portfolio and a
realized gain or loss is recognized. The securities the Fund has agreed to
acquire are included at market value in the portfolio of investments and
liabilities for such purchase commitments are included as payables for
investments purchased. 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.

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

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

(H) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are
recorded on the ex-dividend date. The Fund intends to declare and pay dividends
monthly and capital gain distributions, if any, annually. 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.

The following table discloses the current year reclassifications between
accumulated distributions in excess of net investment income, accumulated net
realized loss on investments, and additional paid-in capital arising from
permanent differences; net assets at October 31, 2004, are not effected.

<Table>

   $(578,931)         $577,366         $1,565
- --------------------------------------------------
</Table>

The reclassifications for the Fund are primarily due to premium amortization
adjustments, real estate investment trusts gain (loss), paydown and foreign
currency gain (loss).

(I) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  The Fund records security
transactions on the trade date. Realized gains and losses on security
transactions are determined using the identified cost method. Dividend income is
recognized on the ex-dividend date and interest income is accrued as earned.
Discounts and premiums on securities, other than short-term securities,
purchased for the Fund 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. Income from payment-in-kind securities is recorded
daily based on the effective interest method of accrual.

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

(J) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred except where direct allocations of expenses can be made. Expenses
(other than expenses incurred under the distribution plans) are allocated to
separate classes of shares based upon their relative net asset value on the date
the expenses are incurred. The expenses borne by the Fund, including those of
related parties to the Fund, are shown in the Statement of Operations.

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

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

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

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

Net realized gain (loss) on foreign currency transactions represents net gains
and losses on foreign currency forward contracts, net currency gains and losses
realized as a result of differences between the amounts of securities sale
proceeds or purchase cost, dividends, interest and withholding taxes as recorded
on the Fund's books, and the U.S. dollar equivalent amount actually received or
paid. Net currency gains or losses from valuing such foreign

 32   MainStay Diversified Income Fund


currency denominated assets and liabilities, other than investments, at year end
exchange rates are reflected in unrealized foreign exchange gains or losses.

(L) 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.

NOTE 3 -- FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER AND SUBADVISOR.  New York Life Investment Management LLC ("NYLIM" or
the "Manager"), an indirect wholly-owned subsidiary of New York Life Insurance
Company ("New York Life"), serves as the Fund's manager. The Manager provides
offices, conducts clerical, recordkeeping and bookkeeping services, and keeps
the financial and accounting records required for the Fund. The Manager also
pays the salaries and expenses of all personnel affiliated with the Fund and all
the operational expenses that are not the responsibility of the Fund. MacKay
Shields LLC (the "Subadvisor"), a registered investment advisor and indirect
wholly-owned subsidiary of New York Life, is responsible for the day-to-day
portfolio management of the Fund.

Through July 31, 2004, the Trust, on behalf of the Fund, paid the Manager a
monthly fee for services performed and the facilities furnished at an annual
rate of 0.60% of the Fund's average daily net assets. Effective August 1, 2004,
the Trust pays the Manager an annual rate of 0.60% of the Fund's average daily
net assets on assets up to $500 million and 0.55% on assets over $500 million.
In addition, effective December 1, 2004, NYLIM has voluntarily agreed to
reimburse the expenses of the Fund to the extent that operating expenses would
exceed on an annualized basis 1.35%, 2.10% and 2.10% of the average daily net
assets of the Class A, Class B and Class C shares, respectively. NYLIM has also
voluntarily agreed to an equivalent reduction in the management fee for Class I
shares. For the year ended October 31, 2004 the Manager earned from the Fund
$764,456.

Pursuant to the terms of a Sub-Advisory Agreement between NYLIM and MacKay
Shields, the Manager pays the Subadvisor a monthly fee at an annual rate of
0.30% of the average daily net assets of the Fund.

(B) DISTRIBUTION AND SERVICE FEES.  The Trust, on behalf of the Fund, has a
Distribution Agreement with NYLIFE Distributors LLC (the "Distributor"), an
indirect wholly-owned subsidiary of New York Life. The Fund, with respect to
each class of shares, has adopted distribution plans (the "Plans") in accordance
with the provisions of Rule 12b-1 under the 1940 Act. Pursuant to the Class A
Plan, the Distributor receives a monthly fee from the Fund at an annual rate of
0.25% of the average daily net assets of the Fund's Class A shares, which is an
expense of the Class A shares of the Fund for distribution or service activities
as designated by the Distributor. Pursuant to the Class B and Class C Plans, the
Fund pays the Distributor a monthly fee, which is an expense of the Class B and
Class C shares of the Fund, at the annual rate of 0.75% of the average daily net
assets of the Fund's Class B and Class C shares. The Distribution Plans provide
that the Class B and Class C shares of the Fund 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 Fund. Class I shares are not subject to a distribution or
service fee.

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

(C) SALES CHARGES.  The Fund was advised by the Distributor that the amount of
sales charges retained on sales of Class A shares was $32,274 for the year ended
October 31, 2004. The Fund was also advised that the Distributor retained
contingent deferred sales charges on redemption of Class A, Class B and Class C
shares of $16,002, $96,166 and $4,628, respectively, for the year ended October
31, 2004.

(D) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT.  NYLIM
Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's
transfer, dividend disbursing and shareholder servicing agent. NYLIM Service has
entered into an agreement with Boston Financial Data Services ("BFDS") pursuant
to which BFDS will perform certain of the services for which NYLIM Service is
responsible. Transfer agent expenses for the year ended October 31, 2004,
amounted to $366,301.

(E) NON-INTERESTED TRUSTEES.  Non-Interested Trustees are paid an annual
retainer fee of $45,000, $2,000 for each Board meeting, $1,000 for each
Committee meeting and $500 for each Valuation Subcommittee telephonic meeting
attended plus reimbursement for travel and out-of-pocket expenses. The Lead
Non-Interested Trustee is also paid an annual retainer fee of $20,000. The Audit
Committee Chairman receives an additional $2,000 for each meeting of the Audit
Committee attended and the Chairpersons of the Brokerage Committee, Operations
Committee and Performance Committee each receive an additional $1,000 for each
meeting of the Brokerage Committee, Operations Committee and Performance
Committee attended, respectively. In addition, each Non-Interested Trustee is
paid $1,000 for attending meetings of the Non-Interested Trustees held in
advance of or in connection with Board/Committee meetings. The Trust allocates
trustees fees in proportion to the net assets of the

                                                    www.mainstayfunds.com     33

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

respective Funds. Thus the Diversified Income Fund only pays a portion of the
fees identified above.

(F) CAPITAL.  At October 31, 2004, NYLIFE Distributors held shares of Class B
with a value of $7,490,203 which represents 9.6% of Class B net assets and 5.8%
of the total Fund's net assets at year end.

(G) OTHER.  Fees for the cost of legal services, included in Professional fees
as shown on the Statement of Operations, provided to the Fund by the Office of
the General Counsel of NYLIM amounted to $3,844 for the year ended October 31,
2004.

The Fund pays the Manager a monthly fee for recordkeeping services provided
under the Accounting Agreement at the annual rate of 1/20 of 1% for the first
$20 million of average monthly net assets, 1/30 of 1% of the next $80 million of
average monthly net assets and 1/100 of 1% of any amount in excess of $100
million of average monthly net assets. Fees for recordkeeping services provided
to the Fund by the Manager amounted to $39,408 for the year ended October 31,
2004.

NOTE 4 -- CUSTODIAN:

The Bank of New York is custodian of cash and securities of the Fund. Custodial
fees are charged the Fund based on the market value of securities in the Fund
and the number of certain cash transactions incurred by the Fund.

NOTE 5 -- RESTRICTED SECURITIES:
RESTRICTED SECURITIES.  A restricted security is a security which has been
purchased through a private offering and cannot be resold to the general public
without prior registration under the Securities Act of 1933 (the "1933 Act").
The Fund does not have the right to demand that such securities be registered.
Disposal of these securities may involve time-consuming negotiations and
expense, and prompt sale at an acceptable price may be difficult.

Restricted securities held at October 31, 2004:

NOTE 6 -- FEDERAL INCOME TAX:

At October 31, 2004, for federal income tax purposes, capital loss carryforwards
of $4,552,109 were available as shown in the table below, to the extent provided
by the regulations to offset future realized gains 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.

primarily due to wash sale deferrals, premium amortization adjustments and bond
reorganizations.

NOTE 12 -- OTHER MATTERS:

NYLIM and mutual funds that NYLIM advises have received requests for information
from various government authorities and regulatory bodies regarding market
timing, late trading, operations, fees, expenses, and other matters. NYLIM and
the funds it advises are cooperating fully in responding to these requests. As
reported in response to those requests for information, NYLIM was previously
party to agreements with certain registered representatives of broker-dealers
relating to the level of trading by clients or customers of those registered
representatives in shares of certain funds of the Trust. NYLIM is continuing to
review what effect, if any, transactions under these agreements may have had on
the funds, and will continue to apprise the Board of Trustees of such
information. NYLIM does not believe at this time that such trading had any
material effect on the funds' financial statements or their shareholders. To
date, substantially all of the costs associated with these and other regulatory
matters have been borne by NYLIM. Except as described below, neither NYLIM nor
the funds advised by it have any reason to believe that they have been targeted
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

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

the related guarantee disclosure to Fund shareholders. Discussions have been
held with the SEC concerning a possible resolution of this matter. These
discussions are continuing, but there can be no assurance at this time as to the
outcome of these efforts.

NOTE 13 -- CHANGE IN INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM (UNAUDITED):

On March 8, 2004, KPMG LLP ("KPMG") was selected as the Trust's independent
auditor for the 2004 fiscal year. The selection of KPMG was recommended by the
Trust's Audit Committee, comprised of all Non-Interested Trustees, and was
approved by the Trust's Board of Trustees.

The predecessor independent auditor's reports on the Trust's financial
statements for the period ended October 31, 2003 and year ended December 31,
2002 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 periods, and through the date of engagement of KPMG, there
were no disagreements between 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 periods.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Trustees and Shareholders of
The MainStay Funds:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of the MainStay Diversified Income Fund (the
"Fund"), one of the funds constituting The MainStay Funds, as of October 31,
2004, and the related statement of operations, statement of changes in net
assets and the financial highlights for the year or period then ended. These
financial statements and financial highlights are the responsibility of the
Fund's management. Our responsibility is to express an opinion on these
financial statements and financial highlights based on our audit. The statement
of changes in net assets for the period ended October 31, 2003 and the year
ended December 31, 2002, and the financial highlights for the periods presented
through October 31, 2003, were audited by other auditors, whose report dated
December 18, 2003 expressed an unqualified opinion thereon.

We conducted our audit in accordance with the Standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
also includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2004 by correspondence with the custodian and
brokers. As to securities purchased or sold but not yet received or delivered,
we performed other appropriate auditing procedures. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
MainStay Diversified Income Fund of The MainStay Funds as of October 31, 2004,
the results of its operations, the changes in its net assets and its financial
highlights for the year or period then ended, in conformity with U.S. generally
accepted accounting principles.

 2   MainStay Strategic Value Fund


MESSAGE FROM
THE PRESIDENT

During the 12 months ended October 31, 2004, the U.S. stock market advanced, but
its pace and direction were by no means steady. Small- and mid-capitalization
stocks tended to outperform large-cap issues, and value stocks generally
outperformed growth stocks.

Economic activity, as measured by gross domestic product, increased from 4.2% in
the fourth quarter of 2003 to 4.5% in the first quarter of 2004. The pace of
economic growth slowed to 3.3% in the second quarter of 2004, and according to
preliminary estimates from the Bureau of Economic Analysis, gross domestic
product grew at a seasonally adjusted annual rate of 3.9% in the third quarter
of 2004.

Interest rates began the reporting period at a low 1.00%. In June 2004, the
Federal Open Market Committee responded to expanding output and improved labor
markets by raising the targeted federal funds rate by 25 basis points. Similar
moves in August and September brought the targeted federal funds rate to 1.75%.
In its September 2004 release, the Federal Open Market Committee affirmed its
belief that monetary policy remained accommodative.

Despite rising interest rates, bond markets generally advanced. High-yield bonds
and emerging-market debt were particularly strong. The U.S. dollar declined
relative to most other currencies, which helped U.S. exporters.

In pursuing its investment objective, each MainStay Fund consistently seeks to
apply a well-defined investment process in all market environments. We believe
that a consistent, disciplined investment approach can help investors make more
prudent and practical decisions regarding their investments.

In the report that follows, you'll find additional information about the market
forces, investment decisions, and individual securities that affected your
MainStay Fund during the 12 months ended October 31, 2004. We thank you for
investing with us, and we look forward to many years of continued service in
your behalf.

Sincerely,

/s/ GARY E. WENDLANDT

Gary E. Wendlandt
President

 4   MainStay Strategic Value Fund


1. The Fund compares itself to a Strategic Value Composite Index that is
   comprised of the Russell 1000(R) Value Index, the Credit Suisse First
   Boston(TM) Convertible Securities Index, and the Credit Suisse First
   Boston(TM) High Yield Index weighted 60%/20%/20%, respectively. The Russell
   1000(R) Value Index is an unmanaged index that measures the performance of
   those Russell 1000(R) companies with lower price-to-book ratios and lower
   forecasted growth values. The Russell 1000(R) Index is an unmanaged index
   that measures the performance of the 1,000 largest U.S. companies based on
   total market capitalization. The Credit Suisse First Boston(TM) Convertible
   Securities Index is an unmanaged index that generally includes 250 to 300
   issues. Convertibles must have a minimum issue size of $50 million; bonds and
   preferreds must be rated B- or better by S&P; and preferreds must have a
   minimum of 500,000 shares outstanding. The Credit Suisse First Boston(TM)
   High Yield Index is an unmanaged market-weighted index that includes publicly
   traded bonds rated below BBB by S&P and below Baa by Moody's. Results assume
   that all income and capital gains are reinvested in the index or indices that
   produce them. The Strategic Value Composite Index is considered to be the
   Fund's broad-based securities-market index for comparison purposes. An
   investment cannot be made directly into an index or this composite.
2. "S&P 500(R)" is a trademark of The McGraw-Hill Companies, Inc. The S&P 500(R)
   is an unmanaged index and is widely regarded as the standard for measuring
   large-cap U.S. stock-market performance. Results assume reinvestment of all
   income and capital gains. An investment cannot be made directly into an
   index.
3. Lipper Inc. is an independent fund performance monitor. Results are based on
   total returns with all dividend and capital-gain distributions reinvested.

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

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 data 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 Donald E. Morgan, Edward Silverstein, and Mark T. Spellman
of MacKay Shields LLC

CAN YOU BRIEFLY DESCRIBE THE FUND'S INVESTMENT APPROACH?

The Fund normally invests in foreign and domestic securities in three asset
classes. Between 30% and 75% of net assets are normally invested in common
stocks that we believe are undervalued, that typically pay dividends, and that
are listed on a national securities exchange or are traded on the over-the-
counter market. The Fund may invest in non-dividend-paying stocks if they meet
the "undervalued" criterion. At least 25% of the Fund's net assets will be
invested in fixed-income securities. The Fund invests 10% to 40% in corporate
debt securities that are ordinarily in the lower rating categories--rated Baa to
B by Moody's or BBB to B by Standard & Poor's(1), or judged to be of comparable
creditworthiness by our portfolio management team. The Fund invests 10% to 40%
in convertible securities in any rating category or unrated. Up to 20% of net
assets may be invested in securities that are rated CCC or below by S&P, at a
comparable level by Moody's,(2) or judged by our portfolio management team to be
of comparable quality.

EQUITIES

WHAT FACTORS AFFECTED THE STOCK MARKET DURING THE 12 MONTHS ENDED OCTOBER 31,
2004?

An improving economy, strong growth in corporate profits, and a relatively
benign interest-rate and inflation outlook helped the market advance. During the
reporting period, there were concerns about higher energy prices, the unsteady
pace of job growth, geopolitical tensions, and election-year politics. The
12-month period ended on a strong note, as the elections approached, energy
prices eased, and stock valuations appeared more attractive to investors.

WHICH VALUE-ORIENTED STOCKS SHOWED STRONG PERFORMANCE DURING THE REPORTING
PERIOD?

Oil and gas driller Transocean (+84%)(3) advanced as pricing and orders
strengthened. Refiners Premcor (+65%) and Valero Energy (+53%) added value as
gasoline inventories continued to shrink and refining margins continued to
improve. We trimmed the position in Premcor and sold Valero Energy as these
stocks approached our price targets.



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.
High-yield securities ("junk bonds") are generally considered speculative
because they present a greater risk of loss than higher-quality debt securities
and may be subject to greater price volatility. Funds that invest in bonds are
subject to interest rate, credit, and inflation risk and can result is loss of
principal when interest rates rise.
1. Bonds rated Baa by Moody's Investors Service are considered by Moody's to be
   medium-grade obligations (i.e., obligations that Moody's believes are neither
   highly protected nor poorly secured). It is Moody's opinion that interest
   payments and principal security appear adequate for the present, but that
   certain protective elements may be lacking or may be characteristically
   unreliable over any great length of time. Moody's believes that such bonds
   lack outstanding investment characteristics and that they in fact have
   speculative characteristics as well. Bonds rated B by Moody's Investors
   Service are deemed by Moody's to generally lack characteristics of the
   desirable investment. According to Moody's, assurance of interest and
   principal payments or of maintenance of other terms of the contract over any
   long period of time may be small. 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. Debt rated B by Standard &
   Poor's is deemed by Standard & Poor's to be more vulnerable to nonpayment
   than obligations rated BB, but it is the opinion of Standard & Poor's that
   the obligor currently has the capacity to meet its financial commitment on
   the obligation. Standard & Poor's believes that adverse business, financial,
   or economic conditions will likely impair the obligor's capacity or
   willingness to meet its financial commitment on the obligation. 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.
2. Debt rated CCC by Standard & Poor's is deemed by Standard & Poor's to be
   currently vulnerable to nonpayment and is dependent upon favorable business,
   financial, and economic conditions for the obligor. It is the opinion of
   Standard & Poor's that in the event of adverse business, financial, or
   economic conditions, the obligor is not likely to have the capacity to meet
   its financial commitment on the obligation. The roughly equivalent rating by
   Moody's is Caa. Bonds rated Caa by Moody's Investors Service are deemed by
   Moody's to be of poor standing. Such issues may be in default or, according
   to Moody's, elements of danger with respect to principal or interest may be
   present. 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.
3. Performance percentages reflect the price performance of the securities
   mentioned for the 12-months ended October 31, 2004, or for the portion of the
   reporting period the securities 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.

ChevronTexaco (+48%) also benefited from higher energy prices. Computer Sciences
(+25%) benefited from government and corporate spending on IT services.

WHICH STOCKS DETRACTED FROM PERFORMANCE IN THE EQUITY PORTION OF THE FUND'S
PORTFOLIO?

Anticipating difficulties at Merck, we reduced the Fund's position in the stock.
Despite the Vioxx recall, we continue to hold Merck shares and are evaluating
our long-term view of the company's prospects. Mortgage insurer Radian Group
hurt the Fund's performance for the year. The shares dropped 17% by February
when we sold the entire position on concerns about the credit quality of the
company's insurance portfolio. Automotive-parts manufacturer TRW Automotive
(-34%) proved to be a premature purchase. We bought the shares for the Fund on
the company's February IPO, but the price fell on concerns about declining
automotive production. We used the opportunity to add to the position.
Papermaker Bowater (-8%) declined as the paper market's recovery proved more
elusive than we had hoped. Near the end of October, the recovery become more
evident. The Fund continues to hold the shares. Insurance broker Marsh &
McLennan was rocked by an investigation by the New York attorney general, and we
decided to sell the Fund's position. The shares were initially purchased in
March and were sold in October, but not before dropping 41%.

HIGH-YIELD BONDS

WHAT KEY TRENDS AFFECTED THE HIGH-YIELD BOND MARKET DURING THE 12 MONTHS ENDED
OCTOBER 31, 2004?

The high-yield bond market advanced as default rates continued to decline from
their peak in 2002. An ongoing economic recovery helped attract new money into
the asset class during the reporting period. The supply of new issuance,
however, failed to keep up with demand. Significant refinancing activity at
lower interest rates tightened yield spreads between high-yield bonds and
comparable investment-grade debt. Interest rate hikes by the Federal Open Market
Committee in June, August, and September of 2004--each of which raised the
targeted federal funds rate by 25 basis points--were widely anticipated by
investors.

HOW DID THE HIGH-YIELD PORTION OF THE FUND'S PORTFOLIO INVEST DURING THE
REPORTING PERIOD?

We found only limited buying opportunities, and we had some concerns regarding
the quality of newly issued securities. The market's refinancing activity led to
higher-than-normal tenders from bond issuers, which increased the Fund's cash
position.

WHAT WERE SOME STRONG PERFORMERS IN THE HIGH-YIELD PORTION OF THE FUND'S
PORTFOLIO DURING THE REPORTING PERIOD?

Some metal-related high-yield bonds--such as AK Steel, Algoma Steel, and
Allegheny Ludlum--were strong performers for the last 12 months, since metals
prices remained solid as North American manufacturing activity increased. Cable
companies, including FrontierVision and UGC Europe, also gained ground during
the reporting period. In December 2003, UnitedGlobalCom acquired all shares of
the recently reorganized UGC Europe. Other cable providers also reported good
earnings over the reporting period.

Several high-yield wireless companies performed well. US Unwired, Alamosa,
Nextel International, and Mobifon each outperformed related securities in the
Credit Suisse First Boston(TM) High Yield Index(4) (the high-yield portion of
the Strategic Value Composite Index). The Fund's holdings in Nextel
International consisted of equity received as the result of a restructuring at
the beginning of 2003.

WERE THERE ANY HIGH-YIELD HOLDINGS THAT DIDN'T MEET YOUR EXPECTATIONS?

High-yield investments in the airline industry had disappointing performance, as
airline costs rose with the rising price of oil. Concerns about a possible
bankruptcy at Delta Airlines affected our position in the company. Delta sought
a resolution with the pilots' union that didn't arrive until the end of October
2004. Delta Airlines and Northwest Airlines were among the Fund's poorest
performers during the reporting period. Other high-yield holdings that produced
disappointing results were securities issued by utilities company Calpine,
restaurant company Family Restaurants, and machinery company Thermadyne
Holdings.

DID YOU MAKE ANY SIGNIFICANT HIGH-YIELD PURCHASES OR SALES DURING THE REPORTING
PERIOD?

The high-yield portion of the Fund's portfolio lost UGC Europe bonds and took on
UnitedGlobalCom debt as part of a corporate action. Other significant additions
to the Fund's portfolio included issues of El Paso Production Holdings, Ono
Finance, Goodyear Tire & Rubber, and Rainbow National Services. We eliminated
Fund holdings in Pacific G&E, Mil-

licom International, and Alamosa PCS Holding. We also sold the Nextel
International holdings the Fund had received during the company's restructuring.

CONVERTIBLE SECURITIES

WHAT MAJOR FACTORS INFLUENCED THE MARKET FOR CONVERTIBLE BONDS DURING THE
12-MONTH REPORTING PERIOD?

For the 12 months ended October 31, 2004, both stocks and bonds rose, pushing
the Credit Suisse First Boston(TM) Convertible Securities Index(5) 7.51% higher.
During the same period, convertible bond spreads relative to Treasuries
contracted 213 basis points, which helped the performance of convertible bonds.

HOW DID THE CONVERTIBLE PORTION OF THE FUND'S PORTFOLIO FARE DURING THE
REPORTING PERIOD?

The risk/reward profile we seek did not match the strongest performers during
the reporting period, which caused the convertible portion of the Fund's
portfolio to underperform the convertible portion of the benchmark. We sought to
reduce the impact of rising interest rates on the Fund's convertible holdings by
focusing on securities that were more sensitive to stock movements than to
interest rates. We also sought to reduce interest-rate sensitivity with bonds
that have relatively short-term maturities, floating interest-rate structures,
put features, or a combination of these characteristics.

HOW DID YOUR INDUSTRY OUTLOOK AFFECT PERFORMANCE IN THE CONVERTIBLE PORTION OF
THE FUND'S PORTFOLIO?

During the reporting period, we significantly overweighted the convertible
portion of the Fund's portfolio in energy-related names, particularly oil
services and equipment companies. This positioning enhanced the Fund's
performance. Our unfavorable outlook for information technology led us to
underweight the sector. Unfortunately, a market weighting in semiconductor
companies hurt performance. An underweighted position in strong-performing
Internet companies, such as Yahoo!, also detracted from performance. We sold
nearly all of the airline holdings in the convertible portion of the Fund's
portfolio on concerns about high fuel prices, overcapacity, high labor costs,
and low barriers to entry.

WHICH SECURITIES IN THE CONVERTIBLE PORTION OF THE FUND'S PORTFOLIO WERE STRONG
PERFORMERS DURING THE REPORTING PERIOD?

The convertible portion of the Fund owned convertible bonds in Halliburton. The
securities significantly outperformed the market, as the company's oil services
and equipment business revenues and profits exceeded analysts' expectations.
Tyco International benefited from a new management team, improved profitability,
significant free cash flow, and a program to retire debt and decrease interest
expense. Devon Energy was a beneficiary of higher energy prices. Transocean
found customers willing to pay higher day rates to lease the company's
equipment. Fisher Scientific shares rose when the company increased its earnings
forecast after several acquisitions during the year. Smurfit-Stone Container, a
box manufacturer, saw its shares advance when demand increased and the declining
dollar gave the company an advantage over foreign competitors. Mandalay Resorts'
convertibles and common stock performed well when the company's newest hotel
property, THE HOTEL, opened with high occupancy rates. The share price of
Mandalay Resorts climbed even more when the company accepted a takeover offer
from MGM Mirage.

WHICH SECURITIES IN THE CONVERTIBLE PORTION OF THE FUND'S PORTFOLIO DETRACTED
FROM PERFORMANCE DURING THE REPORTING PERIOD?

Teva Pharmaceuticals was weak, despite successive earnings reports that handily
beat analysts' expectations. The company was hurt by new competition and concern
about price erosion and disappointing earnings among competitors. Calpine's
shares and convertible bonds declined significantly as the company's
electric-power business was hurt by mild summer weather. Cypress Semiconductor's
shares fell when slowing sales and rising inventories of commodity
semiconductors led to earnings disappointments. Delta Airlines and Alaska Air
were both hurt by the rise in fuel costs and by airline-industry overcapacity
that has forced carriers to lower prices to attract passengers.

WHAT IS YOUR OUTLOOK GOING FORWARD?

We see upside potential in some basic materials and industrial-oriented stocks.
We see less potential in areas of the stock market that depend on consumer
spending. The energy sector may have staying power, based on the price of oil
and foreseeable geopolitical developments. In the high-yield portion of the
portfolio, a stronger economy should help reduce default rates and strengthen
overall market performance. We believe that the Federal Open Market Committee
will continue to raise interest rates into 2005. We will continue to seek
convertible opportunities that we believe offer attractive upside potential with
limited downside risk.

At a meeting on September 21, 2004, the Board of Trustees of The MainStay Funds
(the "Trust") approved an Agreement and Plan of Reorganization whereby all of
the assets and liabilities of the Fund will be transferred to the MainStay

Balanced Fund (the "Reorganization"). Under this Agreement, the Fund would be
completely liquidated after the Reorganization. A meeting of shareholders of the
Fund has been scheduled for January 18, 2005 in order to vote on the proposed
Reorganization. Should shareholders approve a Reorganization, it is scheduled to
be effective on or about the close of business on January 21, 2005.

NOTES TO FINANCIAL STATEMENTS

NOTE 1 -- ORGANIZATION AND BUSINESS:

The MainStay Funds (the "Trust") was organized on January 9, 1986 as a
Massachusetts business trust. The Trust is registered under the Investment
Company Act of 1940, as amended (the "1940 Act"), as an open-end management
investment company and comprises twenty-two funds (collectively referred to as
the "Funds"). These financial statements and notes relate only to MainStay
Strategic Value Fund (the "Fund"), a diversified fund.

The Fund currently offers three classes of shares. Distribution of Class A
shares and Class B shares commenced on October 22, 1997. Class C shares were
initially offered on September 1, 1998. 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 within one year of purchase
of Class C shares. Class A shares, Class B shares and Class C shares bear the
same voting (except for issues that relate solely to one class), dividend,
liquidation and other rights and conditions except that the Class B shares and
Class C shares are subject to higher distribution fee rates. Each class of
shares bears distribution and/or service fee payments under a distribution plan
pursuant to Rule 12b-1 under the 1940 Act.

The Fund's investment objective is to seek maximum long-term total return from a
combination of common stocks, convertible securities and high yield securities.

The Fund invests in high yield securities (sometimes called "junk bonds"), which
are generally considered speculative because they present a greater risk of
loss, including default, than higher quality debt securities. These securities
pay a premium -- a high interest rate or yield -- because of the increased risk
of loss. These securities can also be subject to greater price volatility.

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

NOTE 2 -- SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with generally accepted
accounting principles and follows the significant accounting policies described
below.

(A) SECURITIES VALUATION.  Equity securities are valued at the latest quoted
sales prices as of the close of 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 those prices
are deemed by the Fund's Manager to be representative of market values at the
regular close of business of the Exchange. 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. Securities for which market quotations are not
readily available are valued by methods deemed by the Board of Trustees to
represent fair value. Reasons for which securities may be valued in this manner
include, but are not limited to, trading for a security has been halted or
suspended, a security has been de-listed from a national exchange, or trading on
a security's primary market is temporarily closed at a time when under normal
conditions it would be open. At October 31, 2004, the Fund held securities with
a value of $28,348 that were valued in such manner. Options contracts are valued
at the last posted settlement price on the market where any such options or
futures are principally traded.

Certain events may occur between the time that foreign markets close, on which
securities held by the Fund principally trade, and the time at which the Fund's
NAV is calculated. Should the Manager or Subadvisor conclude that such events
may have effected the accuracy of the last price reported on the local foreign
market, the Manager or Subadvisor may, pursuant to procedures adopted by the
Fund, adjust the value of the local price to reflect the impact on the price of
such securities as a result of such events.

(B) FOREIGN CURRENCY FORWARD CONTRACTS.  A foreign currency forward contract is
an agreement to buy or sell currencies of different countries on a specified
future date at a specified rate. During the period the forward contract is open,
changes in the value of the contract are recognized as unrealized gains or
losses by "marking to market" such contract on a daily basis to reflect the
market value of the contract at the end of each day's trading.

 28   MainStay Strategic Value Fund


When the forward contract is closed, the Fund records a realized gain or loss
equal to the difference between the proceeds from (or cost of) the closing
transaction and the Fund's basis in the contract. The Fund enters into foreign
currency forward contracts primarily to hedge its foreign currency denominated
investments and receivables and payables against adverse movements in future
foreign exchange rates or to try to enhance the Fund's returns.

The use of foreign currency forward contracts involves, to varying degrees,
elements of market risk in excess of the amount recognized in the Statement of
Assets and Liabilities. The contract amount reflects the extent of the Fund's
involvement in these financial instruments. Risks arise from the possible
movements in the foreign exchange rates underlying these instruments. The
unrealized appreciation on forward contracts reflects the Fund's exposure at
period end to credit loss in the event of a counterparty's failure to perform
its obligations.

(C) LOAN ASSIGNMENTS, PARTICIPATIONS AND COMMITMENTS.  The Fund invests in loan
assignments and loan participations. Loan assignments and participations are
agreements to make money available (a "commitment") to a borrower in a specified
amount, at a specified rate and within a specified time. Such loan assignments
and participations are typically senior, secured and collateralized in nature.
The Fund records an investment when the borrower withdraws money and records
interest as earned. These loans pay interest at rates which are periodically
reset by reference to a base lending rate plus a spread. These base lending
rates are generally the prime rate offered by a designated U.S. bank or London
InterBank Offered Rate (LIBOR).

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

The Fund assumes the credit risk of the Borrower, the Selling Participant and
any other persons interpositioned between the Fund and the Borrower
("Intermediate Participants"). In the event that the Borrower, Selling
Participant or Intermediate Participants becomes insolvent or enters into
bankruptcy, the Fund may incur certain costs and delays in realizing payment, or
may suffer a loss of principal and/or interest.

Unfunded commitments represent the remaining obligation of the Fund to the
Borrower. At any point in time, up to the maturity date of the issue, the
Borrower may demand the unfunded portion. These unfunded amounts are recorded in
memorandum accounts. (See Note 7.)

(D) PURCHASED AND WRITTEN OPTIONS.  The Fund may write covered call and put
options on its 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 cancelled in closing purchase
transactions are added to the proceeds or netted against the amount paid on the
transaction to determine the realized gain or loss. By writing a covered call
option, the Fund foregoes in exchange for the premium 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, the Fund, in exchange for the premium, accepts the risk of a decline in
the market value of the underlying security or foreign currency below the
exercise price. A call option may be covered by the call writer's owning the
underlying security throughout the option period. A call option may also be
covered by the call writer's maintaining liquid assets valued at greater than
the exercise price of the call written, in a segregated account with its
custodian.

The Fund may purchase call and put options on its portfolio securities. The Fund
may purchase call options to protect against an increase in the price of the
security it anticipates purchasing or to seek to enhance returns. The Fund may
purchase put options on its securities to protect against a decline in the value
of the security or to close out covered written put positions. Risks may arise
from an imperfect correlation between the change in market value of the
securities held by the Fund and the prices of options relating to the securities
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.

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

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

(F) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are
recorded on the ex-dividend date. The Fund intends to declare and pay dividends
quarterly and capital gain distributions, if any, annually. 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.

                                                    www.mainstayfunds.com     29

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

The following table discloses the current year reclassification between
accumulated undistributed net investment income, accumulated net realized loss
on investments, and additional paid-in capital arising from permanent
differences; net assets at October 31, 2004, are not affected.

    $28,201       $(27,678)      $(523)
- ----------------------------------------------
</Table>

The reclassifications for the Fund are primarily due to premium amortization
adjustments, foreign currency gain (loss), and paydown gain (loss).

(G) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  The Fund records security
transactions on the trade date. Realized gains and losses on security
transactions are determined using the identified cost method. Dividend income is
recognized on the ex-dividend date and interest income is accrued as earned.
Discounts and premiums on securities, other than short-term securities purchased
for the Fund 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. Income from payment-in-kind securities is recorded daily based on
the effective interest method of accrual.

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

(H) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred except where direct allocations of expenses can be made. Expenses
(other than expenses incurred under the distribution plans) are allocated to
separate classes of shares based upon their relative net asset value on the date
the expenses are incurred. The expenses borne by the Fund, including those of
related parties to the Fund, are shown in the Statement of Operations.

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

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

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

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

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

(J) 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.

NOTE 3 -- FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER AND SUBADVISOR.  New York Life Investment Management LLC ("NYLIM" or
the "Manager"), an indirect wholly-owned subsidiary of New York Life Insurance
Company ("New York Life"), serves as the Fund's Manager. The Manager provides
offices, conducts clerical, recordkeeping and bookkeeping services, and keeps
the financial and accounting records required for the Fund. The Manager also
pays the salaries and expenses of all personnel affiliated with the Fund and all
the operational expenses that are not the responsibility of the Fund. MacKay
Shields LLC (the "Subadvisor"), a registered investment advisor and indirect
wholly-owned subsidiary of New York Life, is responsible for the day-to-day
portfolio management of the Fund.

Through July 31, 2004, the Trust, on behalf of the Fund, paid the Manager a
monthly fee for services performed and the facilities furnished at an annual
rate of 0.75% of the Fund's average daily net assets. The Manager had
voluntarily agreed to reimburse the expenses of the Fund to the extent that
operating expenses would exceed on an annualized basis 1.70%, 2.45% and 2.45% of
the average

 30   MainStay Strategic Value Fund


daily net assets of the Class A, Class B and Class C shares, respectively.
Effective August 1, 2004, the Trust pays the Manager an annual rate of 0.75% of
the Fund's average daily net assets on assets up to $500 million and 0.70% on
assets over $500 million. In addition, effective December 1, 2004, NYLIM has
voluntarily agreed to reimburse the expenses of the Fund to the extent that
operating expenses would exceed on an annualized basis 1.40%, 2.15% and 2.15% of
the average daily net assets of the Class A, Class B and Class C shares,
respectively. For the year ended October 31, 2004, the Manager earned from the
Fund $370,612 and reimbursed the Fund $144,698.

Pursuant to the terms of a Sub-Advisory Agreement between NYLIM and MacKay
Shields, the Manager paid the Subadvisor a monthly fee at an annual rate of
0.375% of the average daily net assets of the Fund. To the extent the Manager
has agreed to reimburse expenses of the Fund, the Subadvisor has voluntarily
agreed to do so proportionately.

(B) DISTRIBUTION AND SERVICE FEES.  The Trust, on behalf of the Fund, has a
Distribution Agreement with NYLIFE Distributors LLC (the "Distributor"), an
indirect wholly-owned subsidiary of New York Life. The Fund, with respect to
each class of shares, has adopted distribution plans (the "Plans") in accordance
with the provisions of Rule 12b-1 under the 1940 Act. Pursuant to the Class A
Plan, the Distributor receives a monthly fee from the Fund at an annual rate of
0.25% of the average daily net assets of the Fund's Class A shares, which is an
expense of the Class A shares of the Fund for distribution or service activities
as designated by the Distributor. Pursuant to the Class B and Class C Plans, the
Fund pays the Distributor a monthly fee, which is an expense of the Class B and
Class C shares of the Fund, at the annual rate of 0.75% of the average daily net
assets of the Fund's Class B and Class C shares. The distribution plans provide
that the Class B and Class C shares of the Fund 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 Fund.

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

(C) SALES CHARGES.  The Fund was advised by the Distributor that the amount of
sales charges retained on sales of Class A shares was $11,973 for the year ended
October 31, 2004. The Fund was also advised that the Distributor retained

2004.

A restricted security is a security which has been purchased through a private
offering and cannot be resold to the general public without prior registration
under the Securities Act of 1933. The Fund does not have the right to demand
that such securities be registered. Disposal of these securities may involve
time-consuming negotiations and expense, and prompt sale at an acceptable price
may be difficult.

As of October 31, 2004, the components of accumulated gain on a tax basis were
as follows:

     UNDISTRIBUTED    ACCUMULATED                      TOTAL
        ORDINARY      CAPITAL AND     UNREALIZED    ACCUMULATED

- ---------------------------------------------------------------
</Table>

The difference between book-basis and tax-basis unrealized appreciation is
primarily due to wash sale deferrals, premium amortization adjustments and bond
reorganizations.

At October 31, 2004, for federal income tax purposes, capital loss carryforwards
of $2,004,747 were available as shown in the table below, to the extent provided
by the regulations to offset future realized gains of the Fund through the years
indicated. To the extent that these loss

 32   MainStay Strategic Value Fund


carryforwards are used to offset future capital gains, it is probable that the
capital gains so offset will not be distributed to shareholders.

NOTE 9 -- LINE OF CREDIT:
The Fund and certain affiliated funds maintain a line of credit of $160,000,000
with a syndicate of banks in order to secure a source of funds for temporary
purposes to meet unanticipated or excessive shareholder redemption requests. The
funds pay a commitment fee, at an annual rate of .075% of the average commitment
amount, regardless of usage, to The Bank of New York, which acts as agent to the
syndicate. Such commitment fees are allocated among the funds based upon net
assets and other factors. Interest on any revolving credit loan is charged based
upon the Federal Funds Advances rate. There were no borrowings on the line of
credit during the year ended October 31, 2004.

The Board of Trustees of the Trust has called a Special Meeting of Shareholders
("Special Meeting") of the Fund, scheduled to be held on January 18, 2005. At
the Special Meeting, shareholders will vote on a proposed reorganization of the

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

NOTE 12 -- OTHER MATTERS:

NYLIM and mutual funds that NYLIM advises have received requests for information
from various government authorities and regulatory bodies regarding market
timing, late trading, operations, fees, expenses, and other matters. NYLIM and
the funds it advises are cooperating fully in responding to these requests. As
reported in response to those requests for information, NYLIM was previously
party to agreements with certain registered representatives of broker-dealers
relating to the level of trading by clients or customers of those registered
representatives in shares of certain funds of the Trust. NYLIM is continuing to
review what effect, if any, transactions under these agreements may have had on
the funds, and will continue to apprise the Board of Trustees of such
information. NYLIM does not believe at this time that such trading had any
material effect on the funds' financial statements or their shareholders. To
date, substantially all of the costs associated with these and other regulatory
matters have been borne by NYLIM. Except as described below, neither NYLIM nor
the funds advised by it have any reason to believe that they have been targeted
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.
Discussions have been held with the SEC concerning a possible resolution of this
matter. These discussions are continuing, but there can be no assurance at this
time as to the outcome of these efforts.

NOTE 13 -- CHANGE IN INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM (UNAUDITED):

On March 8, 2004, KPMG LLP ("KPMG") was selected as the Trust's independent
auditor for the 2004 fiscal year. The selection of KPMG was recommended by the
Trust's Audit Committee, comprised of all Non-Interested Trustees, and was
approved by the Trust's Board of Trustees.

The predecessor independent auditor's reports on the Trust's financial
statements for the period ended October 31, 2003 and year ended December 31,
2002 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 periods, and through the date of engagement of KPMG, there
were no disagreements between 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 periods.

 34   MainStay Strategic Value Fund


REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Trustees and Shareholders of
The MainStay Funds:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of the MainStay Strategic Value Fund (the "Fund"),
one of the funds constituting The MainStay Funds, as of October 31, 2004, and
the related statement of operations, statement of changes in net assets and the
financial highlights for the year then ended. These financial statements and
financial highlights are the responsibility of the Fund's management. Our
responsibility is to express an opinion on these financial statements and
financial highlights based on our audit. The statement of changes in net assets
for the period ended October 31, 2003 and the year ended December 31, 2002, and
the financial highlights for the periods presented through October 31, 2003,
were audited by other auditors, whose report dated December 18, 2003 expressed
an unqualified opinion thereon.

We conducted our audit in accordance with the Standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
also includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2004 by correspondence with the custodian and
brokers. As to securities purchased or sold but not yet received or delivered,
we performed other appropriate auditing procedures. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
MainStay Strategic Value Fund of The MainStay Funds as of October 31, 2004, the
results of its operations, the changes in its net assets and its financial
highlights for the year then ended, in conformity with U.S. generally accepted
accounting principles.

MESSAGE FROM
THE PRESIDENT

During the 12 months ended October 31, 2004, the U.S. stock market advanced, but
its pace and direction were by no means steady. Small- and mid-capitalization
stocks tended to outperform large-cap issues, and value stocks generally
outperformed growth stocks.

Economic activity, as measured by gross domestic product, increased from 4.2% in
the fourth quarter of 2003 to 4.5% in the first quarter of 2004. The pace of
economic growth slowed to 3.3% in the second quarter of 2004, and according to
preliminary estimates from the Bureau of Economic Analysis, gross domestic
product grew at a seasonally adjusted annual rate of 3.9% in the third quarter
of 2004.

Interest rates began the reporting period at a low 1.00%. In June 2004, the
Federal Open Market Committee responded to expanding output and improved labor
markets by raising the targeted federal funds rate by 25 basis points. Similar
moves in August and September brought the targeted federal funds rate to 1.75%.
In its September 2004 release, the Federal Open Market Committee affirmed its
belief that monetary policy remained accommodative.

Despite rising interest rates, bond markets generally advanced. High-yield bonds
and emerging-market debt were particularly strong. The U.S. dollar declined
relative to most other currencies, which helped U.S. exporters.

In pursuing its investment objective, each MainStay Fund consistently seeks to
apply a well-defined investment process in all market environments. We believe
that a consistent, disciplined investment approach can help investors make more
prudent and practical decisions regarding their investments.

In the report that follows, you'll find additional information about the market
forces, investment decisions, and individual securities that affected your
MainStay Fund during the 12 months ended October 31, 2004. We thank you for
investing with us, and we look forward to many years of continued service in
your behalf.

Sincerely,

/s/ GARY E. WENDLANDT

Gary E. Wendlandt
President

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

Questions answered by portfolio manager Howard F. Ward of Gabelli Asset
Management Company

CAN YOU DESCRIBE THE FUND'S INVESTMENT STRATEGY?

The Fund normally invests at least 80% of its total assets in common stocks and
other securities issued by U.S. blue-chip companies. We define blue-chip firms
as those possessing leading market characteristics and certain financial
characteristics. These companies generally have market capitalizations of at
least $2 billion and revenues greater than $500 million. In implementing this
strategy, we look for companies that we believe have superior earnings-
per-share growth prospects and above-average or expanding market shares, profit
margins, and returns on equity.

WHAT MAJOR FACTORS INFLUENCED THE STOCK MARKET DURING THE 12 MONTHS ENDED
OCTOBER 31, 2004?

When the reporting period began, the economy appeared to be on sound footing.
Many of the positive fundamentals that contributed to calendar year 2003's rise
in prices remained solidly in place. With the stock market rising, investor
demand for equities was strong, and on December 11, 2003, the Dow Jones
Industrial Average(1) closed above 10,000 for the first time in nearly 20
months. Toward the end of January 2004, the Dow Jones Industrial Average and the
Nasdaq(R) Composite Index(2) both reached levels not seen since before September
11, 2001. The chief factor boosting the stock market's rise was the dramatic
improvement in corporate profits.

In February 2004, however, the stock market began to stagnate as investor
confidence began to wane. Despite continued economic growth and strength in
corporate profits that remained throughout the first half of 2004, the stock
market had a difficult time gaining traction. At various times, investors
appeared preoccupied with any number of issues--from economic uncertainty and
inflationary pressures to interest-rate prospects and terrorism concerns. The
stock market subsequently moved modestly lower during the third quarter of 2004.
One could argue that the market held up relatively well in the face of
persistent concerns, including continued hostilities in Iraq and sharply rising
oil prices. Near the end of October 2004, the market rallied, as oil prices
moderated somewhat and third-quarter corporate profits trended higher.

WHICH STOCKS WERE AMONG THE FUND'S STRONG PERFORMERS FOR THE REPORTING PERIOD?

Among the stocks held throughout the entire fiscal year, the five best
performers were QUALCOMM (+75.2%),(3) eBay (+74.6%), Symantec (+70.9%),
Starbucks (+67.3%), and Occidental Petroleum (+58.3%). Digital wireless leader
QUALCOMM rose steadily throughout the period on solid fundamental performance.
While most wireless chipset makers experienced mixed results during the Fund's
fiscal year, QUALCOMM surpassed earnings expectations during the fourth quarter
2003 and in the first and second quarters of 2004. In addition, earnings grew
over 50% during the company's fiscal year, which ended September 2004.

WHICH STOCKS DETRACTED FROM THE FUND'S PERFORMANCE?

The five worst-performing stocks were Veritas Software (-39.4%), Tiffany
(-38.2%), Charles Schwab (-32.5%), Intel (-32.4%), and Applied Materials
(-31.0%). Shares of storage software vendor VERITAS suffered first in January
2004 and then again in July 2004. Both declines followed announcements that
sales would be below analysts' projections. The Fund's position in VERITAS was
relatively small (0.4% at period end), and in both instances, we felt that the
stock's decline was not justified.

WERE THERE ANY SIGNIFICANT PURCHASES DURING THE REPORTING PERIOD?

We added a number of new holdings to the portfolio during the 12-month period.
Our aim was to find companies with strong growth prospects selling at reasonable
valuations as we sought to add depth and diversity to the Fund. New investments
during the first quarter of 2004, albeit relatively small, were Panera Bread,
RARE Hospitality International, and CheckFree. We also made initial investments
in Burlington Resources and British Petroleum during that period. Later in the
Fund's fiscal year, we added Suncor Energy, which extracts oil from Canadian oil
sands; Newmont Mining, a leading gold producer; Alcoa, a leading aluminum
producer; and Caterpillar,

a mining- and construction-equipment manufacturer. We also added farm-equipment
manufacturer Deere, biotech companies Genzyme and Genentech, and Internet
retailer Amazon.com.

WHICH POSITIONS DID THE FUND SELL OR REDUCE DURING THE REPORTING PERIOD?

Early in 2004, we began to trim various technology positions on strength, and we
sold the Fund's holding in W.M. Wrigley to fund new purchases. We also began to
trim the Fund's holding in Marsh & McLennan. The company was well-publicized
because of problems at its Putnam unit. We eventually eliminated the position
entirely during the second quarter of 2004, on concerns about mounting
investigations. We also eliminated holdings in Mellon and Omnicom in March 2004
and Nokia in May 2004. Nokia had disappointing earnings in both the fourth
quarter of 2003 and the first quarter of 2004. In the third quarter of 2004, we
reduced the Fund's exposure to several information technology companies,
including Symantec, QUALCOMM, Microchip Technology, Applied Materials, and
Xilinx.

HOW DID THE FUND CHANGE ITS SECTOR WEIGHTINGS?

During the 12-month reporting period, we reduced the Fund's exposure to the
consumer discretionary, financials and information technology sectors. Over the
same period, we increased exposure to the consumer staples, energy, health care,
and industrials sectors.

The reduction in the consumer discretionary sector came from our decision to
trim once-large positions in several leading media companies. In financial
services, we eliminated two significant holdings for company-specific reasons
and began to trim other holdings when it became apparent that we were entering a
rising interest-rate environment. In the information technology sector, we began
selling into strength early in 2004, after a very strong showing in many of the
Fund's information technology holdings during 2003. We continued to use the
information technology sector as a source of funds throughout the year, as
consistently high oil prices contributed to a moderation of economic growth that
we believed was likely to continue into 2005.

In consumer staples, we added to some of the Fund's existing holdings during the
summer of 2004, after they had sold off a bit. Amid growing fears about rising
oil prices, the geopolitical situation, and slowing economic growth, we felt
that investors would begin to favor the predictable earnings streams of consumer
staples companies. The Fund's exposure in the energy sector increased both from
additional investments and from significant capital appreciation as oil prices
surged. In the health care sector, we added several positions in the health care
equipment & services industry group, along with new holdings in biotechnology.
In the industrials sector, we purchased a number of new stocks and added to some
existing positions.

WHAT DO YOU ANTICIPATE GOING FORWARD?

During the second- and third-quarter 2004 earnings seasons, many companies
reported that rising labor and energy costs were making it difficult to attain
their margin goals. While overall earnings and revenues were robust, we wonder
whether we will see further margin pressure in the coming quarters. In
particular, we believe that oil prices could substantially influence economic
activity, earnings, and the stock market.

Since the economy appears (in the words of Federal Reserve Chairman Greenspan)
to have "regained some traction," we anticipate additional rate hikes at least
until the targeted federal funds rate is equal to the inflation rate, which
seems to be running between 2% and 3%.

We believe that it is currently more difficult than usual to place confidence in
economic or stock-market forecasts. There are simply too many important
unknowns, including oil prices, Iraq, China's growth rate, and Federal Reserve
policy. At this point, the primary drivers of stock prices--earnings, interest
rates, and inflation expectations--appear relatively benign. But other factors,
such as oil prices, may exert greater influence in the short-run. It's our
belief, however, that corporate earnings will ultimately drive the equity
markets.

NOTES TO FINANCIAL STATEMENTS

NOTE 1 -- ORGANIZATION AND BUSINESS:

The MainStay Funds (the "Trust") was organized on January 9, 1986 as a
Massachusetts business trust. The Trust is registered under the Investment
Company Act of 1940, as amended (the "1940 Act"), as an open-end management
investment company and is comprised of twenty-two funds (collectively referred
to as the "Funds"). These financial statements and notes relate only to MainStay
Blue Chip Growth Fund (the "Fund"), a diversified fund.

The Fund currently offers three classes of shares. Distribution of Class A
shares and Class B shares commenced on June 1, 1998. Class C shares were
initially offered on September 1, 1998. 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 within one year of purchase
of Class C shares. Class A shares, Class B shares and Class C shares bear the
same voting (except for issues that relate solely to one class), dividend,
liquidation and other rights and conditions except that the Class B shares and
Class C shares are subject to higher distribution fee rates. Each class of
shares bears distribution and/or service fee payments under a distribution plan
pursuant to Rule 12b-1 under the 1940 Act.

The Fund's investment objective is to seek capital appreciation by investing
primarily in securities of large-capitalization companies. Current income is a
secondary investment objective.

NOTE 2 -- SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with generally accepted
accounting principles and follows the significant accounting policies described
below.

(A) SECURITIES VALUATION.  Equity securities are valued at the latest quoted
sales prices as of the close of 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. 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.
Securities for which market quotations are not readily available are valued by
methods deemed by the Board of Trustees to represent fair value. Reasons for
which securities may be valued in this manner include, but are not limited to,
trading for a security has been halted or suspended, a security has been
de-listed from a national exchange, or trading on a security's primary market is
temporarily closed at a time when under normal conditions it would be open. The
Fund did not hold securities at October 31, 2004, that were valued in such
manner.

(B) 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.

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

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

(D) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are
recorded on the ex-dividend date. The Fund intends to declare and pay any
dividends quarterly and capital gains distributions, if any, annually. 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.

The following table discloses the current year reclassification between
accumulated net investment loss and additional paid-in-capital arising from
permanent differences; net assets at October 31, 2004, are not affected.

<Table>
<Caption>
  ACCUMULATED NET     ADDITIONAL
  INVESTMENT LOSS   PAID-IN CAPITAL
                 

    $4,577,338       $(4,577,338)
</Table>

 18   MainStay Blue Chip Growth Fund


The reclassification for the Fund is due to the fact that net operating losses
cannot be carried forward for federal income tax purposes.

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

Investment income and realized and unrealized gains and losses on investments of
the 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.

(F) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred except where direct allocations of expenses can be made. Expenses
(other than expenses incurred under the distribution plans) are allocated to
separate classes of shares based upon their relative net asset value on the date
the expenses are incurred. The expenses borne by the Fund, including those of
related parties to the Fund, are shown in the Statement of Operations.

(G) USE OF ESTIMATES.  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.

NOTE 3 -- FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER AND SUBADVISOR.  New York Life Investment Management LLC ("NYLIM" or
the "Manager"), an indirect wholly-owned subsidiary of New York Life Insurance
Company ("New York Life"), serves as the Fund's manager. The Manager provides
offices, conducts clerical, record-keeping and bookkeeping services, and keeps
the financial and accounting records required for the Fund. The Manager also
pays the salaries and expenses of all personnel affiliated with the Fund and all
the operational expenses that are not the responsibility of the Fund. Gabelli
Asset Management Company (the "Subadvisor") is responsible for the day-to-day
portfolio management of the Fund.

Through July 31, 2004, the Trust, on behalf of the Fund, paid the Manager a
monthly fee for services performed and the facilities furnished at an annual
rate of 1.00% of the Fund's average daily net assets. Effective August 1, 2004,
the Trust pays the Manager an annual rate of 1.00% of the Fund's average daily
net assets on assets up to $500 million and 0.95% on assets over $500 million.
Also effective August 1, 2004, NYLIM had voluntarily agreed to waive its
management fee by 0.20% of the Fund's average net assets. In addition, effective
December 1, 2004, NYLIM has voluntarily agreed to reimburse the expenses of the
Fund to the extent that operating expenses would exceed on an annualized basis
1.50%, 2.25% and 2.25% of the average daily net assets of the Class A, Class B
and Class C shares, respectively. For the year ended October 31, 2004, the
Manager earned from the Fund $2,685,493 and waived $126,090 of its fee.

Pursuant to the terms of a Sub-Advisory Agreement between NYLIM and the
Subadvisor, the Manager paid the Subadvisor a monthly fee at an annual rate of
0.50% of the average daily net assets of the Fund.

(B) DISTRIBUTION AND SERVICE FEES.  The Trust, on behalf of the Fund, has a
Distribution Agreement with NYLIFE Distributors LLC (the "Distributor"). The
Fund, with respect to each class of shares, has adopted distribution plans (the
"Plans") in accordance with the provisions of Rule 12b-1 under the 1940 Act.
Pursuant to the Class A Plan, the Distributor receives a monthly fee from the
Fund at an annual rate of 0.25% of the average daily net assets of the Fund's
Class A shares, which is an expense of the Class A shares of the Fund for
distribution or service activities as designated by the Distributor. Pursuant to
the Class B and Class C Plans, the Fund pays the Distributor a monthly fee,
which is an expense of the Class B and Class C shares of the Fund, at the annual
rate of 0.75% of the average daily net assets of the Fund's Class B and Class C
shares. The Distribution Plans provide that the Class B and Class C shares of
the Fund 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 Fund.

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

(C) SALES CHARGES.  The Fund was advised by the Distributor that the amount of
sales charges retained on sales of Class A shares was $30,054 for the year ended
October 31, 2004. The Fund was also advised that the Distributor retained
contingent deferred sales charges on redemptions of Class A, Class B and Class C
shares of $2,766, $289,913 and $1,004, respectively, for the year ended October
31, 2004.

(D) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT.  NYLIM
Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's
transfer, dividend disbursing and shareholder servicing agent. NYLIM Service has
entered into an agreement with Boston Financial Data Services ("BFDS") pursuant
to which BFDS will perform certain of the services for which NYLIM Service is
responsible. Transfer agent expenses for the year ended October 31, 2004,
amounted to $1,701,966.

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

(E) NON-INTERESTED TRUSTEES FEES.  Non-Interested Trustees are paid an annual
retainer fee of $45,000, $2,000 for each Board meeting, $1,000 for each
Committee meeting and $500 for each Valuation Subcommittee telephonic meeting
attended plus reimbursement for travel and out-of-pocket expenses. The Lead
Non-Interested Trustee is also paid an annual retainer fee of $20,000. The Audit
Committee Chairman receives an additional $2,000 for each meeting of the Audit
Committee attended and the Chairpersons of the Brokerage Committee, Operations
Committee and Performance Committee each receive an additional $1,000 for each
meeting of the Brokerage Committee, Operations Committee and Performance
Committee attended, respectively. In addition, each Non-Interested Trustee is
paid $1,000 for attending meetings of the Non-Interested Trustees held in
advance of or in connection with Board/Committee meetings. The Trust allocates
trustees fees in proportion to the net assets of the respective Funds. Thus the
Blue Chip Growth Fund only pays a portion of the fees identified above.

(F) OTHER.  Fees for the cost of legal services, included in Professional fees
as shown on the Statement of Operations, provided to the Fund by the Office of
the General Counsel of NYLIM amounted to $7,876 for the year ended October 31,
2004.

The Fund pays the Manager a monthly fee for recordkeeping services provided
under the Accounting Agreement at the annual rate of 1/20 of 1% for the first
$20 million of average monthly net assets, 1/30 of 1% of the next $80 million of
average monthly net assets and 1/100 of 1% of any amount in excess of $100
million of average monthly net assets. Fees for recordkeeping services provided
to the Fund by the Manager amounted to $53,521 for the year ended October 31,
2004.

NOTE 4 -- CUSTODIAN:

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

NOTE 5 -- FEDERAL INCOME TAX:

As of October 31, 2004, the components of accumulated loss on a tax basis were
as follows:

<Table>
<Caption>
  ACCUMULATED CAPITAL    UNREALIZED    TOTAL ACCUMULATED
   AND OTHER LOSSES     APPRECIATION         LOSS
                                 
    $(184,497,356)       $9,621,295     $(174,876,061)
</Table>

The difference between book-basis and tax-basis unrealized appreciation is
primarily due to wash sale deferrals.

At October 31, 2004, for federal income tax purposes, capital loss carryforwards
of $184,497,356 were available as shown in the table below, to the extent
provided by the regulations to offset future realized gains 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 6 -- PURCHASES AND SALES OF SECURITIES (IN 000'S):

During the year ended October 31, 2004, purchases and sales of securities, other
than securities subject to repurchase transactions and short-term securities,
were $83,818 and $113,507, respectively.

NOTE 7 -- LINE OF CREDIT:

The Fund and certain affiliated funds maintain a line of credit of $160,000,000
with a syndicate of banks in order to secure a source of funds for temporary
purposes to meet unanticipated or excessive shareholder redemption requests. The
funds pay a commitment fee, at an annual rate of .075% of the average commitment
amount, regardless of usage, to The Bank of New York, which acts as agent to the
syndicate. Such commitment fees are allocated among the funds based upon net
assets and other factors. Interest on any revolving credit loan is charged based
upon the Federal Funds Advances rate. There were no borrowings on the line of
credit during the year ended October 31, 2004.

NOTE 9 -- OTHER MATTERS:

NYLIM and mutual funds that NYLIM advises have received requests for information
from various government authorities and regulatory bodies regarding market
timing, late trading, operations, fees, expenses, and other matters. NYLIM and
the funds it advises are cooperating fully in responding to these requests. As
reported in response to those requests for information, NYLIM was previously
party to agreements with certain registered representatives of broker-dealers
relating to the level of trading by clients or customers of those registered
representatives in shares of certain funds of the Trust. NYLIM is continuing to
review what effect, if any, transactions under these agreements may have had on
the funds, and will continue to apprise the Board of Trustees of such
information. NYLIM does not believe at this time that such trading had any
material effect on the funds' financial statements or their shareholders. To
date, substantially all of the costs associated with these and other regulatory
matters have been borne by NYLIM. Except as described below, neither NYLIM nor
the funds advised by it have any reason to believe that they have been targeted
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.
Discussions have been held with the SEC concerning a possible resolution of this
matter. These discussions are continuing, but there can be no assurance at this
time as to the outcome of these efforts.

NOTE 10 -- CHANGE IN INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM (UNAUDITED):

On March 8, 2004, KPMG LLP ("KPMG") was selected as the Trust's independent
auditor for the 2004 fiscal year. The selection of KPMG was recommended by the
Trust's Audit Committee, comprised of all Non-Interested Trustees, and was
approved by the Trust's Board of Trustees.

The predecessor independent auditor's reports on the Trust's financial
statements for the period ended October 31, 2003 and year ended December 31,
2002 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 periods, and through the date of engagement of KPMG, there
were no disagreements between 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 periods.

                                                    www.mainstayfunds.com     21


REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Trustees and Shareholders of
The MainStay Funds:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of the MainStay Blue Chip Growth Fund (the
"Fund"), one of the funds constituting The MainStay Funds, as of October 31,
2004, and the related statement of operations, statement of changes in net
assets and the financial highlights for the year then ended. These financial
statements and financial highlights are the responsibility of the Fund's
management. Our responsibility is to express an opinion on these financial
statements and financial highlights based on our audit. The statement of changes
in net assets for the period ended October 31, 2003 and the year ended December
31, 2002, and the financial highlights for the periods presented through October
31, 2003, were audited by other auditors, whose report dated December 18, 2003
expressed an unqualified opinion thereon.

We conducted our audit in accordance with the Standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
also includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2004 by correspondence with the custodian and
brokers. As to securities purchased or sold but not yet received or delivered,
we performed other appropriate auditing procedures. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
MainStay Blue Chip Growth Fund of The MainStay Funds as of October 31, 2004, the
results of its operations, the changes in its net assets and its financial
highlights for the year then ended, in conformity with U.S. generally accepted
accounting principles.

 2   MainStay Mid Cap Value Fund


MESSAGE FROM
THE PRESIDENT

During the 12 months ended October 31, 2004, the U.S. stock market advanced, but
its pace and direction were by no means steady. Small- and mid-capitalization
stocks tended to outperform large-cap issues, and value stocks generally
outperformed growth stocks.

Economic activity, as measured by gross domestic product, increased from 4.2% in
the fourth quarter of 2003 to 4.5% in the first quarter of 2004. The pace of
economic growth slowed to 3.3% in the second quarter of 2004, and according to
preliminary estimates from the Bureau of Economic Analysis, gross domestic
product grew at a seasonally adjusted annual rate of 3.9% in the third quarter
of 2004.

Interest rates began the reporting period at a low 1.00%. In June 2004, the
Federal Open Market Committee responded to expanding output and improved labor
markets by raising the targeted federal funds rate by 25 basis points. Similar
moves in August and September brought the targeted federal funds rate to 1.75%.
In its September 2004 release, the Federal Open Market Committee affirmed its
belief that monetary policy remained accommodative.

Despite rising interest rates, bond markets generally advanced. High-yield bonds
and emerging-market debt were particularly strong. The U.S. dollar declined
relative to most other currencies, which helped U.S. exporters.

In pursuing its investment objective, each MainStay Fund consistently seeks to
apply a well-defined investment process in all market environments. We believe
that a consistent, disciplined investment approach can help investors make more
prudent and practical decisions regarding their investments.

In the report that follows, you'll find additional information about the market
forces, investment decisions, and individual securities that affected your
MainStay Fund during the 12 months ended October 31, 2004. We thank you for
investing with us, and we look forward to many years of continued service in
your behalf.

Sincerely,

/s/ GARY E. WENDLANDT

Gary E. Wendlandt
President

Performance tables and graphs do not reflect the deduction of taxes that a
shareholder would pay on distributions or Fund-share redemptions. Total returns
reflect change in share price, reinvestment of dividend and capital-gain
distributions, and maximum applicable sales charges explained in this paragraph.
The graphs assume an initial investment of $10,000 and reflect the deduction of
all sales charges that would have applied for the period of investment. Class A
shares are sold with a maximum initial sales charge of 5.5% and an annual 12b-1
fee of .25%. Class B shares are sold with no initial sales charge, are subject
to a contingent deferred sales charge (CDSC) of up to 5% if redeemed within the
first six years of purchase, and have an annual 12b-1 fee of 1.00%. Class C
shares are sold with no initial sales charge, are subject to a CDSC of 1% if
redeemed within one year of purchase, and have an annual 12b-1 fee of 1.00%.
Class I shares are sold with no initial sales charge or CDSC, have no annual
12b-1 fee, and are generally available to corporate and institutional investors
with a minimum initial investment of $5 million. Class R1 shares are sold with
no initial sales charge or CDSC and have no annual 12b-1 fee. Class R2 shares
are sold with no initial sales charge or CDSC and have an annual 12b-1 fee of
..25%. Class R1 and R2 shares are available only through corporate-sponsored
retirement programs, which include certain minimum program requirements.
Performance figures reflect certain fee waivers and/or expense limitations,
without which total returns may have been lower. The fee waivers and/or expense
limitations are voluntary and may be discontinued at any time. From inception
(6/1/98) through 8/31/98, performance for Class C shares (first offered 9/1/98)
includes the historical performance of Class B shares adjusted to reflect the
applicable CDSC for Class C shares. From inception (6/1/98) through 12/31/03,
performance for Class I, R1, and R2 shares (first offered 1/2/04) includes the
historical performance of Class A shares adjusted to reflect the applicable fees
and expenses for Class I, R1, and R2 shares.

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

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 data 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 Michael C. Sheridan and Richard A.
Rosen of MacKay Shields LLC

CAN YOU BRIEFLY DESCRIBE THE FUND'S INVESTMENT APPROACH?

The Fund normally invests at least 80% of its assets in common and preferred
stock of companies with market capitalizations that at the time of investment
are similar to those of companies in the Russell Midcap(R) Value Index.(1) In
implementing this strategy, we seek to identify investment opportunities based
on the financial condition and competitiveness of individual companies. In
particular, we look for firms that we deem to be undervalued based on a number
of factors, including relative valuation, ability to grow dividends, and
corporate management.

WHAT MAJOR FACTORS INFLUENCED THE STOCK MARKET DURING THE 12 MONTHS ENDED
OCTOBER 31, 2004?

Accommodative worldwide monetary policies and generally low interest rates led
to rapid global economic growth. Demand for raw materials was particularly
strong from emerging Asian countries, including China and India. Sharply rising
prices for energy and commodities helped energy and basic materials stocks
generate strong performance. Industrial stocks also benefited from strong global
growth. Despite economic expansion, interest rates generally remained quite low,
allowing interest-rate-sensitive sectors, such as financials and utilities, to
provide solid gains.

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

The Fund's overweighted position in the energy sector enhanced results during
the 12 months ended October 31, 2004. Our decision to underweight the health
care sector also helped the Fund's performance. Strong stock selection in the
information technology and telecommunications services sectors also had a
beneficial impact. On the other hand, the Fund's underweighted position in
utilities, coupled with poor stock selection in the consumer discretionary,
industrials, and materials sectors detracted from the Fund's results.

DID THE FUND CHANGE ANY OF ITS WEIGHTINGS?

When the reporting period began, the Fund held an overweighted position in the
energy sector. In late 2003, we became even more convinced that the sector's
fundamentals would continue to improve amid strong demand and global production
constraints. For these reasons, we further increased the Fund's exposure in the
energy sector in January 2004.

Early in the reporting period, the Fund's investments in exploration and
production companies and in refiners generated strong results. As the reporting
period progressed, the Fund's exploration and production holdings approached
what we believed to be fair valuations, and we reduced the Fund's exposure to
these companies. We used the proceeds to gradually increase the portfolio's
exposure to lagging offshore drilling companies that we felt were poised to
benefit from higher spending trends.

WHAT WERE SOME OF THE FUND'S SUCCESS STORIES?

Transocean, the world's largest offshore drilling company, appreciated 83.7%(2)
during the reporting period. Utilization of the company's high-specification
drillships and semisubmersible rigs reached nearly full capacity, and
Transocean's day rates increased dramatically. Another strong performer was
Cummins (+51.2%). This diesel-engine producer benefited from the robust increase
in demand for commercial trucks. We recently reduced the Fund's position, as we
felt the stock was approaching fair value. Kerr-McGee (+48.0%), an oil and
natural gas exploration and production company and a chemical producer, also
enhanced the Fund's results. The stock rose as Kerr-McGee generated strong
earnings and cash flows, which were driven by the dramatic rise in oil and gas
prices.

WHICH STOCKS DETRACTED FROM THE FUND'S RESULTS DURING THE REPORTING PERIOD?

On the heels of previous successes, Navistar International (-14.5%) was a
disappointment during the reporting period. The company did not fully capitalize
on the strong upturn in commercial-vehicle demand. Manufacturing inefficiencies
produced by a far-reaching and aggressive restructuring program were partly to
blame. Golf-equipment manufacturer

Mid-capitalization companies are generally less established and their stocks may
be more volatile and less liquid than the securities of large companies.

   holdings may differ from the performance of the securities or sectors

Callaway Golf (-34.6%) suffered from aggressive competition from its
well-financed competitors Titleist (owned by Fortune Brands) and Taylor Made
(owned by Adidas). The Callaway Golf position has been removed from the
portfolio.

Another stock that detracted from results was Bowater (-8.0%), a manufacturer of
coated paper and newsprint. Bowater's stock declined as advertising and
help-wanted pages in newspapers remained depressed. Newsprint is a highly
consolidated industry that may be on the cusp of an upturn in light of
encouraging new-job creation and pricing increases. We believe that a weaker
U.S. dollar may also help Bowater's product lines, and the Fund continues to
hold the stock in its portfolio.

WERE THERE ANY SIGNIFICANT PURCHASES DURING THE REPORTING PERIOD?

As previously discussed, we increased the Fund's holdings in offshore drillers.
Specific holdings added to the portfolio during the reporting period included
Transocean, Diamond Offshore, Rowan Companies, Ensco International, and Pride
International.

WHAT STOCKS WERE ELIMINATED DURING THE PERIOD?

Valero Energy (+103.2%) is the largest independent refiner in North America.
While the company benefited from strong earnings and record refining margins,
the position was eliminated from the portfolio as it reached our price
objective.

Payless Shoesource, a leading shoe retailer, suffered from poor same-store sales
comparisons, as higher energy costs left consumers with less discretionary
income. The company also suffered from bloated inventories, which led to price
markdowns. These factors prompted us to sell the stock. We also eliminated the
Fund's position in food and drug retailer Safeway (-13.5%), as the company
suffered from strike-related costs and sales shortfalls. We used the proceeds
from the Safeway sale to purchase shares of its peer Kroger, a company that we
felt was better positioned as a grocery retailer.

WHAT IS YOUR OUTLOOK GOING FORWARD?

We currently perceive the market as providing both excellent opportunities and
high levels of risk. We believe the Fund is appropriately positioned for these
dynamics. We continue to see opportunities in the energy sector in general, and
offshore drillers in particular. Basic materials producers are just starting to
enjoy a positive mix of increasing demand, high factory operating rates, low
inventories, and price increases. We feel that a weaker U.S. dollar should
disproportionately benefit U.S.-based producers whose securities are held by the
Fund. In the industrials sector, we anticipate increased demand for commercial
vehicles and transport volumes. Should this occur, several Fund holdings could
benefit.

At the same time, we have sought to underweight risk-laden areas of the market
and carefully choose stocks in these sectors. In the financials sector, for
example, we are concerned about high bank valuations, little apparent new-loan
demand, and potential for credit deterioration. Based on our assessment of
long-term valuations, real estate investment trusts (REITs) and utilities both
appear overvalued. Consumer cyclicals appear overvalued, with some areas trading
at very high or even record valuations. We believe that all of these areas look
extremely vulnerable to higher interest rates, a weaker dollar, and continued
high energy prices. For these reasons, the Fund has underweighted all of these
areas, which together comprise a substantial portion of the Russell MidCap(R)

Value Index.

NOTES TO FINANCIAL STATEMENTS

NOTE 1 -- ORGANIZATION AND BUSINESS:

The MainStay Funds (the "Trust") was organized on January 9, 1986 as a
Massachusetts business trust. The Trust is registered under the Investment
Company Act of 1940, as amended (the "1940 Act"), as an open-end management
investment company and comprises twenty-two funds (collectively referred to as
the "Funds"). These financial statements and notes relate only to MainStay Mid
Cap Value Fund (the "Fund"), a diversified fund.

The Fund currently offers six classes of shares, Class A shares, Class B shares,
Class C shares, Class I shares, Class R1 shares and Class R2 shares.
Distribution of Class A shares and Class B shares commenced on June 1, 1998.
Class C shares were initially offered on September 1, 1998. Distribution of
Class I shares, Class R1 shares and Class R2 shares commenced on January 2,
2004. 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 within one year of purchase of Class C shares. Class I shares, Class R1
shares and Class R2 shares are not subject to sales charge. The six classes bear
the same voting (except for issues that relate solely to one class), dividend,
liquidation and other rights and conditions except that Class B shares and Class
C shares are subject to higher distribution fee rates than Class A shares and
Class R2 shares under a distribution plan pursuant to Rule 12b-1 under the 1940
Act. Class I shares and Class R1 shares are not subject to a distribution or
service fee. Class R1 and Class R2 shares are authorized to pay to New York Life
Investment Management LLC, its affiliates, or independent third-party service
providers, as compensation for services rendered to shareholders of Class R1 or
Class R2 shares, a shareholder service fee.

The Fund's investment objective is to realize maximum long-term total return
from a combination of capital appreciation and income.

Effective January 1, 2004, the Fund changed its name to MainStay Mid Cap Value
Fund from MainStay Equity Income Fund.

NOTE 2 -- SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with generally accepted
accounting principles and follows the significant accounting policies described
below.

(A) SECURITIES VALUATION.  Equity securities are valued at the latest quoted
sales prices as of the close of 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
selected by the Fund's Manager, whose prices reflect broker/dealer supplied
valuations and electronic data processing techniques if those prices are deemed
by the Fund's Manager to be representative of market values at the regular close
of business of the New York Stock Exchange. 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. Securities for which market quotations are not
readily available are valued by methods deemed by the Board of Trustees to
represent fair value. Reasons for which securities may be valued in this manner
include, but are not limited to, trading for a security has been halted or
suspended, a security has been de-listed from a national exchange, or trading on
a security's primary market is temporarily closed at a time when under normal
conditions it would be open. The Fund did not hold securities at October 31,
2004, that were valued in such manner.

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

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

(C) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are
recorded on the ex-dividend date. The Fund intends to declare and pay any
dividends quarterly and capital gain distributions, if any, annually. 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.

The following table discloses the current year reclassifications between
accumulated net investment loss, accumulated net realized gain and additional
paid-in-capital arising

 16   MainStay Mid Cap Value Fund


from permanent differences; net assets at October 31, 2004, are not affected.

<Table>

  ACCUMULATED      ACCUMULATED

      LOSS             GAIN        PAID-IN CAPITAL
                            
    $760,694         $330,209        $(1,090,903)
</Table>

The reclassifications for the Fund are primarily due to a reclassification of
real estate investment trust distributions and net operating losses.

(D) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  The Fund records security
transactions on the trade date. Realized gains and losses on security
transactions are determined using the identified cost method. Dividend income is
recognized on the ex-dividend date and interest income is accrued as earned.
Discounts and premiums on securities, other than short-term securities,
purchased for the Fund are accreted and amortized, respectively to interest
income, 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
the Fund are allocated to separate classes of shares based upon their relative
net assets on the date the income is earned or realized and unrealized gains and
losses are incurred.

(E) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred except where direct allocations of expenses can be made. Expenses
(other than expenses incurred under the distribution plans) are allocated to
separate classes of shares based upon their relative net asset value on the date
the expenses are incurred. The expenses borne by the Fund, including those of
related parties to the Fund, are shown in the Statement of Operations.

(F) USE OF ESTIMATES.  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.

NOTE 3 -- FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER AND SUBADVISOR.  New York Life Investment Management LLC ("NYLIM" or
the "Manager"), an indirect wholly-owned subsidiary of New York Life Insurance
Company ("New York Life"), serves as the Fund's manager. The Manager provides
offices, conducts clerical, recordkeeping and bookkeeping services, and keeps
the financial and accounting records required for the Fund. The Manager also
pays the salaries and expenses of all personnel affiliated with the Fund and all
the operational expenses that are not the responsibility of the Fund. MacKay
Shields LLC (the "Subadvisor"), a registered investment advisor and indirect
wholly-owned subsidiary of New York Life, is responsible for the day-to-day
portfolio management of the Fund.

Through July 31, 2004, the Trust, on behalf of the Fund, paid the Manager a
monthly fee for services performed and the facilities furnished at an annual
rate of 0.70% of the Fund's average daily net assets. The Manager had
voluntarily agreed to reimburse the expenses of the Fund to the extent that
operating expenses would exceed on an annualized basis 1.65%, 2.40% and 2.40% of
the average daily net assets of the Class A, Class B and Class C shares,
respectively. NYLIM had agreed to an equivalent reduction in the management fee
for Class I, Class R1 and Class R2 shares. Effective August 1, 2004, the Trust
pays the Manager an annual rate of 0.70% of the Fund's average daily net assets
on assets up to $500 million and 0.65% on assets over $500 million. In addition,
effective December 1, 2004, NYLIM has voluntarily agreed to reimburse the
expenses of the Fund to the extent that operating expenses would exceed on an
annualized basis 1.35%, 2.10% and 2.10% of the average daily net assets of the
Class A, Class B and Class C shares, respectively and an equivalent reduction in
the management fee for Class I, Class R1 and Class R2 shares. For the year ended
October 31, 2004, the Manager earned from the Fund $2,285,484. It was not
necessary for the Manager to reimburse the Fund for expenses for the year ended
October 31, 2004.

Pursuant to the terms of a Sub-Advisory Agreement between NYLIM and the
Subadvisor, the Manager paid the Subadvisor a monthly fee at an annual rate of
0.35% of the average daily net assets of the Fund.

(B) DISTRIBUTION AND SERVICE FEES.  The Trust, on behalf of the Fund, has a
Distribution Agreement with NYLIFE Distributors LLC (the "Distributor"), an
indirect wholly-owned subsidiary of New York Life. The Fund, with respect to
Class A, Class B, Class C and Class R2 shares, has adopted distribution plans
(the "Plans") in accordance with the provisions of Rule 12b-1 under the 1940
Act. Pursuant to the Class A and Class R2 Plan, the Distributor receives a
monthly fee from the Fund at an annual rate of 0.25% of the average daily net
assets of the Fund's Class A and Class R2 shares, which is an expense of the
Class A and Class R2 shares of the Fund for distribution or service activities
as designated by the Distributor. Pursuant to the Class B and Class C Plans, the
Fund pays the Distributor a monthly fee, which is an expense of the Class B and
Class C shares of the Fund, at the annual rate of 0.75% of the average daily net
assets of the Fund's Class B and Class C shares. The Distribution Plans provide
that the Class B and Class C shares of the Fund also incur a service

                                                    www.mainstayfunds.com     17

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

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 Fund. Class I shares and Class R1 shares are
not subject to a distribution or service fee.

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

The Fund has adopted a shareholder services plan with respect to Class R1 and R2
shares. Under the terms of this plan, Class R1 and Class R2 shares are
authorized to pay to NYLIM, its affiliates, or independent third-party
providers, as compensation for services rendered, a shareholder service fee at
the rate of 0.10% of the average daily net assets of the Fund's Class R1 and R2
shares.

(C) SALES CHARGES.  The Fund was advised by the Distributor that the amount of
sales charges retained on sales of Class A shares was $60,940 for the year ended
October 31, 2004. The Fund was also advised that the Distributor retained
contingent deferred sales charges on redemptions of Class A, Class B and Class C
shares of $5,351, $236,730 and $5,869, respectively, for the year ended October
31, 2004.

(D) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT.  NYLIM
Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's
transfer, dividend disbursing and shareholder servicing agent. NYLIM Service has
entered into an agreement with Boston Financial Data Services ("BFDS") pursuant
to which BFDS will perform certain of the services for which NYLIM Service is
responsible. Transfer agent expenses for the year ended October 31, 2004,
amounted to $1,195,902.

(E) NON-INTERESTED TRUSTEES FEES.  Non-Interested Trustees are paid an annual
retainer fee of $45,000, $2,000 for each Board meeting, $1,000 for each
Committee meeting and $500 for each Valuation Subcommittee telephonic meeting
attended plus reimbursement for travel and out-of-pocket expenses. The Lead
Non-Interested Trustee is also paid an annual retainer fee of $20,000. The Audit
Committee Chairman receives an additional $2,000 for each meeting of the Audit
Committee attended and the Chairpersons of the Brokerage Committee, Operations
Committee and Performance Committee each receive an additional $1,000 for each
meeting of the Brokerage Committee, Operations Committee and Performance
Committee attended, respectively. In addition, each Non-Interested Trustee is
paid $1,000 for attending meetings of the Non-Interested Trustees held in
advance of or in connection with Board/Committee meetings. The Trust allocates
trustees fees in proportion to the net assets of the respective Funds. Thus the
Mid Cap Value Fund only pays a portion of the fees identified above.

(F) OTHER.  Fees for the cost of legal services, included in Professional fees
as shown on the Statement of Operations, provided to the Fund by the Office of
the General Counsel of NYLIM amounted to $10,258 for the year ended October 31,
2004.

The Fund pays the Manager a monthly fee for recordkeeping services provided
under the Accounting Agreement at the annual rate of 1/20 of 1% for the first
$20 million of average monthly net assets, 1/30 of 1% of the next $80 million of
average monthly net assets and 1/100 of 1% of any amount in excess of $100
million of average monthly net assets. Fees for recordkeeping services provided
to the Fund by the Manager amounted to $59,317 for the year ended October 31,
2004.

NOTE 4 -- CUSTODIAN:

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

NOTE 5 -- FEDERAL INCOME TAX:

As of October 31, 2004, the components of accumulated gain on a tax basis were
as follows:

<Table>
<Caption>
     ACCUMULATED          UNREALIZED     TOTAL ACCUMULATED
    REALIZED GAIN        APPRECIATION          GAIN
                                  
      $5,477,932         $46,804,725        $52,282,657
</Table>

The differences between book-basis and tax-basis unrealized appreciation is
primarily due to wash sale deferrals and real estate investment trust
distributions.

The Fund utilized $9,192,455 of capital loss carryforwards during the year ended
October 31, 2004.

The tax character of distributions paid during the year ended October 31, 2004,
the ten months ended October 31, 2003 and the year ended December 31, 2002,
shown in the Statement of Changes in Net Assets, are as follows:

syndicate. Such commitment fees are allocated among the funds based upon net
assets and other factors. Interest on any revolving credit loan is charged based

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

NOTE 9 -- OTHER MATTERS:

NYLIM and mutual funds that NYLIM advises have received requests for information
from various government authorities and regulatory bodies regarding market
timing, late trading, operations, fees, expenses, and other matters. NYLIM and
the funds it advises are cooperating fully in responding to these requests. As
reported in response to those requests for information, NYLIM was previously
party to agreements with certain registered representatives of broker-dealers
relating to the level of trading by clients or customers of those registered
representatives in shares of certain funds of the Trust. NYLIM is continuing to
review what effect, if any, transactions under these agreements may have had on
the funds, and will continue to apprise the Board of Trustees of such
information. NYLIM does not believe at this time that such trading had any
material effect on the funds' financial statements or their shareholders. To
date, substantially all of the costs associated with these and other regulatory
matters have been borne by NYLIM. Except as described below, neither NYLIM nor
the funds advised by it have any reason to believe that they have been targeted
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.
Discussions have been held with the SEC concerning a possible resolution of this
matter. These discussions are continuing, but there can be no assurance at this
time as to the outcome of these efforts.

NOTE 10 -- CHANGE IN INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM (UNAUDITED):

On March 8, 2004, KPMG LLP ("KPMG") was selected as the Trust's independent
auditor for the 2004 fiscal year. The selection of KPMG was recommended by the
Trust's Audit Committee, comprised of all Non-Interested Trustees, and was
approved by the Trust's Board of Trustees.

The predecessor independent auditor's reports on the Trust's financial
statements for the period ended October 31, 2003, and year ended December 31,
2002 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 periods, and through the date of engagement of KPMG, there
were no disagreements between 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 periods.

 20   MainStay Mid Cap Value Fund


REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Trustees and Shareholders of
The MainStay Funds:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of the MainStay Mid Cap Value Fund (the "Fund"),
one of the funds constituting The MainStay Funds, as of October 31, 2004, and
the related statement of operations, statement of changes in net assets and the
financial highlights for the year or period then ended. These financial
statements and financial highlights are the responsibility of the Fund's
management. Our responsibility is to express an opinion on these financial
statements and financial highlights based on our audit. The statement of changes
in net assets for the period ended October 31, 2003 and the year ended December
31, 2002, and the financial highlights for the periods presented through October
31, 2003, were audited by other auditors, whose report dated December 18, 2003
expressed an unqualified opinion thereon.

We conducted our audit in accordance with the Standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
also includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2004 by correspondence with the custodian and
brokers. As to securities purchased or sold but not yet received or delivered,
we performed other appropriate auditing procedures. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
MainStay Mid Cap Value Fund of The MainStay Funds as of October 31, 2004, the
results of its operations, the changes in its net assets and its financial
highlights for the year or period then ended, in conformity with U.S. generally
accepted accounting principles.

 2   MainStay Global High Income Fund


MESSAGE FROM
THE PRESIDENT

During the 12 months ended October 31, 2004, the U.S. stock market advanced, but
its pace and direction were by no means steady. Small- and mid-capitalization
stocks tended to outperform large-cap issues, and value stocks generally
outperformed growth stocks.

Economic activity, as measured by gross domestic product, increased from 4.2% in
the fourth quarter of 2003 to 4.5% in the first quarter of 2004. The pace of
economic growth slowed to 3.3% in the second quarter of 2004, and according to
preliminary estimates from the Bureau of Economic Analysis, gross domestic
product grew at a seasonally adjusted annual rate of 3.9% in the third quarter
of 2004.

Interest rates began the reporting period at a low 1.00%. In June 2004, the
Federal Open Market Committee responded to expanding output and improved labor
markets by raising the targeted federal funds rate by 25 basis points. Similar
moves in August and September brought the targeted federal funds rate to 1.75%.
In its September 2004 release, the Federal Open Market Committee affirmed its
belief that monetary policy remained accommodative.

Despite rising interest rates, bond markets generally advanced. High-yield bonds
and emerging-market debt were particularly strong. The U.S. dollar declined
relative to most other currencies, which helped U.S. exporters.

In pursuing its investment objective, each MainStay Fund consistently seeks to
apply a well-defined investment process in all market environments. We believe
that a consistent, disciplined investment approach can help investors make more
prudent and practical decisions regarding their investments.

In the report that follows, you'll find additional information about the market
forces, investment decisions, and individual securities that affected your
MainStay Fund during the 12 months ended October 31, 2004. We thank you for
investing with us, and we look forward to many years of continued service in
your behalf.
Sincerely,
/s/ GARY E. WENDLANDT

Gary E. Wendlandt

President

Performance tables and graphs do not reflect the deduction of taxes that a
shareholder would pay on distributions or Fund-share redemptions. Total returns
reflect change in share price, reinvestment of dividend and capital-gain
distributions, and maximum applicable sales charges explained in this paragraph.
The graphs assume an initial investment of $10,000 and reflect the deduction of
all sales charges that would have applied for the period of investment. Class A
shares are sold with a maxi-mum 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%.
Performance figures reflect certain fee waivers and/or expense limitations,
without which total returns may have been lower. The fee waivers and/or expense
limitations are voluntary and may be discontinued at any time. From inception

 4   MainStay Global High Income Fund


1. The J.P. Morgan EMBI Global Diversified Index is an unmanaged, uniquely
   weighted version of The J.P. Morgan Emerging Markets Bond Index--the
   EMBI--which, in turn, is an unmanaged, market-capitalization weighted,
   total-return index tracking the traded market for U.S. dollar denominated
   Brady bonds. The EMBI Global Diversified Index limits the weights of those
   index countries with larger total debt obligations by only including
   specified portions of these countries' eligible current face amounts of
   outstanding debt. Results assume reinvestment of all income and capital
   gains. The EMBI Global Diversified Index is considered to be the Fund's
   broad-based securities-market index for comparison purposes. An investment
   cannot be made directly into an index or a composite.

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

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY GLOBAL HIGH INCOME FUND

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 data 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 Gary Goodenough, Joseph Portera, and
Jeffrey M. Saxon of MacKay Shields LLC

CAN YOU BRIEFLY DESCRIBE THE FUND'S INVESTMENT APPROACH?

The Fund normally invests at least 65% of its assets in high-yield securities,
including debt issued by governments, their agencies and authorities, and
corporations that are located in at least three different countries. The Fund
principally invests in emerging markets but may also invest in established
economies. In implementing this strategy, we seek to identify investment
opportunities with an approach that includes country selection, local currency
evaluation, and individual security analysis based on such factors as financial
condition and competitiveness. We may consider a country's political stability,
currency exchange rates, interest rates, inflation, relative economic growth,
and governmental policies.

WHAT FACTORS INFLUENCED EMERGING-MARKET DEBT DURING THE 12-MONTH REPORTING
PERIOD?

During the reporting period, emerging-market debt provided strong performance.
We attribute these results to improving credit trends that have been in place
for several years. The market is anticipating that early next year, Argentina
will resolve its debt default. Demand has remained strong as relatively low
interest rates have drawn investors to higher-yielding securities.

WHAT ISSUES AFFECTED THE MANAGEMENT OF THE FUND DURING THE 12-MONTH PERIOD?

Improving credit fundamentals and default resolution in several countries were
key positives for the market, and these factors drove most of our investment
decisions during the reporting period. At the beginning of the Fund's fiscal
year, the prospect that U.S. interest rates might rise adversely affected the
Fund, since most of the securities we hold are in U.S. dollars. In addition,
rising U.S. interest rates generally have a negative impact on countries that
depend on external demand, which is the case for most emerging-market economies.
On the other hand, stronger-than-expected growth in Asia was beneficial for
commodity exporters. Higher oil prices were also positive for issuers such as
Venezuela. Corporate bonds in emerging markets also made a comeback. The
improvements were dominated by oil companies and other commodity providers but
also included other types of companies.

HOW DID YOU POSITION THE FUND'S PORTFOLIO IN THIS ENVIRONMENT?

Our focus on identifying issuers with free cash flow led us to increase the
Fund's exposure in telecommunications, utilities, and consumer-oriented
companies. We believe that our emphasis on seeking value and prudently managing
risk was what allowed the Fund to outperform the market during the reporting
period.

The Fund held overweighted positions in oil- and commodity-rich countries, such
as Russia, Venezuela, Algeria, Nigeria, and Ecuador. The high price of oil
helped to substantially improve the balance sheets of these countries during the
reporting period. For example, Russia has seen its foreign-currency reserves
rise to nearly $100 billion dollars, nearly equal to the total amount of
Russia's external outstanding debt.

WERE THERE ANY COUNTRY-SPECIFIC FACTORS THAT WERE NOTEWORTHY?

Emerging debt markets are often affected by politics. Ecuador's political
problems were overshadowed by higher oil prices, which helped the country's
bonds. The nation's bonds also benefited from strategic cabinet adjustments the
president made to balance the Congress and retain power.

Venezuela's referendum to remove its president added to uncertainty, but in the
end it had little impact on bond prices. The Fund had been overweighted in
Venezuelan debt for most of the period, but we have since taken profits, and the
Fund is now closer to neutral relative to the J.P. Morgan EMBI Global
Diversified Index.(1) Russia and Ecuador remain significantly overweighted in
the Fund. We continue to look for opportunities to add to the Fund's Russian
exposure as we expect that Russian government bonds will receive a rating
upgrade within the next six months.

Brazil and Turkey were comparatively risky and volatile markets during the
reporting period. Follow-

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.
High-yield securities ("junk bonds") are generally considered speculative
because they present a greater risk of loss than higher-quality debt securities
and may be subject to greater price volatility. The Fund may invest in
derivatives, which may increase the volatility of the Fund's net asset value and
may result in a loss to the Fund. Funds that invest in bonds are subject to
credit, inflation, and interest-rate risk and can lose principal value when
interest rates rise.

ing the Turkish general election at the end of 2002, many wondered whether the
new conservative government would be able to pursue European Union membership
and whether the European Union would welcome a conservative Muslim government.
When discussions got underway, there appeared to be room for negotiation.
Turkish debt rallied on the positive news. Brazilian debt sold off dramatically
during the second quarter of 2004, as rising Brazilian and U.S. interest rates
had a negative impact on performance. Despite this setback, Brazil's securities
advanced on evidence that interest rates would rise at a measured pace and that
the country's fiscal situation was improving.

HAVE YOU FOUND ANY OPPORTUNITIES IN THE ARGENTINE MARKET?

Long-term investors in the Fund may recall that we avoided the Argentine default
back in 2001. Indeed, with the exception of oil giant Repsol YPF, the Fund has
avoided the Argentine market. Early in 2004, we carefully analyzed the country's
fundamentals and determined that the yields being offered presented a compelling
opportunity. We first added Argentine Bodens--debt that had already been
restructured and was up-to-date on its interest and principal payments. Later in
the year, as we sensed that a deal was likely on external debt, we added
defaulted debt to the portfolio.

WHAT TYPES OF CORPORATE BONDS DID THE PORTFOLIO HOLD?

During the reporting period, we increased the Fund's exposure to corporate
bonds. Since these bonds are typically perceived as having more risk than
government debt, they usually provide a higher yield and may offer solid
opportunities for emerging-market-debt investors. Our credit research helped us
uncover select securities in the oil, steel, utilities, beverages, and telecom
industries. In particular, we believe we've identified a number of well-managed
companies that are benefiting from strong global and domestic demand, prudent
balance-sheet management, and favorable pricing. These factors helped the Fund's
corporate bonds outperform their sovereign (or government) counterparts over the
12 months ended October 31, 2004.

WERE THERE ANY HOLDINGS THAT DETRACTED FROM RESULTS?

Given our global mandate, we occasionally look for opportunities in developed
markets. During the reporting period, the Fund added bonds issued by
Ireland-based crystal and ceramics maker Waterford Wedgwood. We believed that,
as a manufacturer of luxury brands, the company had strong underlying value.
What's more, its bonds were yielding approximately 600 basis points over
comparable Treasury debt. (A basis point is 1/100th of one percent.)
Unfortunately, the company began to weaken early in 2004, leading us to question
management's business plan. We sold the Fund's holdings toward the end of the
reporting period, which resulted in a small loss for the Fund.

WHERE WILL YOU PLACE YOUR FOCUS IN THE COMING MONTHS?

Looking into 2005, we remain optimistic. While we can't predict where commodity
prices will go from here, we remain confident that demand--especially from
Asia--will support prices for the medium term. We expect U.S. interest rates to
move higher, since we believe that the Federal Reserve will maintain its
tightening bias until at least the second quarter of 2005. We feel that
political uncertainty will remain a factor. How President Bush handles fiscal
policy in his second term may affect the shape of the U.S. yield curve, but not
the overall direction of interest rates.

Technically, we believe that emerging markets will continue to benefit from
investors' search for higher-yielding investments. Credit fundamentals remain
positive as well, with Argentina coming out of default and Russian government
debt likely to be upgraded. On the corporate front, we are also optimistic and
expect more credit upgrades than downgrades. It's our belief that the increasing
depth of local-market issuance will help support debt tied to the U.S. dollar,
since countries such as Mexico may have less of a need to issue foreign-currency
debt for deficit funding. As always, we will continue to pursue our investment
discipline, and we appreciate the support of the Fund's shareholders.

NOTES TO FINANCIAL STATEMENTS

NOTE 1 -- ORGANIZATION AND BUSINESS:

The MainStay Funds (the "Trust") was organized on January 9, 1986 as a
Massachusetts business trust. The Trust is registered under the Investment
Company Act of 1940, as amended (the "1940 Act"), as an open-end management
investment company and comprises twenty-two funds (collectively referred to as
the "Funds"). These financial statements and notes relate only to MainStay
Global High Income Fund (the "Fund").

The Fund currently offers three classes of shares. Distribution of Class A
shares and Class B shares commenced on June 1, 1998. Class C shares were
initially offered on September 1, 1998. 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 within one year of purchase
of Class C shares. Class A shares, Class B shares and Class C shares bear the
same voting (except for issues that relate solely to one class), dividend,
liquidation and other rights and conditions except that the Class B shares and
Class C shares are subject to higher distribution fee rates. Each class of
shares bears distribution and/or service fee payments under a distribution plan
pursuant to Rule 12b-1 under the 1940 Act.

The Fund's investment objective is to seek to provide maximum current income by
investing primarily in high yield debt securities of non-U.S. issuers. Capital
appreciation is a secondary objective. MainStay Global High Income Fund is
"non-diversified," which means that it may invest a greater percentage of its
assets than diversified funds in a particular issuer. This may make it more
susceptible than diversified funds to risks associated with an individual
issuer, and to single economic, political or regulatory occurrences.

The Fund principally invests in high yield securities (sometimes called "junk
bonds"), which are generally considered speculative because they present a
greater risk of loss, including default, than higher quality debt securities.
These securities pay a premium--a high interest rate or yield--because of the
increased risk of loss. These securities can also be subject to greater price
volatility.

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

Effective January 1, 2004, the Fund changed its name to MainStay Global High
Income Fund from MainStay Global High Yield Fund.

NOTE 2 -- SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with generally accepted
accounting principles and follows the significant accounting policies described
below.

(A) SECURITIES VALUATION.  Debt securities are valued at prices supplied by a
pricing agent selected by the Fund's Manager, whose prices reflect broker/dealer
supplied valuations and electronic data processing techniques if those prices
are deemed by the Fund's Manager to be representative of market values at the
regular close of business of the New York Stock Exchange. 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. Securities for which market
quotations are not readily available are valued by methods deemed by the Board
of Trustees to represent fair value. Reasons for which securities may be valued
in this manner include, but are not limited to, trading for a security has been
halted or suspended, a security has been de-listed from a national exchange, or
trading on a security's primary market is temporarily closed at a time when
under normal conditions it would be open. The Fund did not hold securities at
October 31, 2004, that were valued in such manner. Foreign currency forward
contracts are valued at their fair market values determined on the basis of the
mean between the last current bid and asked prices based on dealer or exchange
quotations.

Certain events may occur between the time that foreign markets close, on which
securities held by the Fund principally trade, and the time at which the Fund's
NAV is calculated. These events may include, but are not limited to, situations
relating to a single issue in a market sector, significant fluctuations in U.S.
or foreign markets, natural disasters, armed conflicts, governmental actions or
other developments not tied directly to the securities markets. Should the
Manager or Subadvisor conclude that such events may have affected the accuracy
of the last price reported on the local foreign market, the Manager or
Subadvisor may, pursuant to procedures adopted by the Fund, adjust the value of
the local price to reflect the impact on the price of such securities as a
result of such events.

 20   MainStay Global High Income Fund


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

The use of foreign currency forward contracts involves, to varying degrees,
elements of market risk in excess of the amount recognized in the Statement of
Assets and Liabilities. The contract amount reflects the extent of the Fund's
involvement in these financial instruments. Risks arise from the possible
movements in the foreign exchange rates underlying these instruments. The
unrealized appreciation on forward contracts reflects the Fund's exposure at
year end to credit loss in the event of a counterparty's failure to perform its
obligations.

(C) SECURITIES LENDING.  The Fund may lend its securities to broker-dealers and
financial institutions. The loans are collateralized by cash or securities at
least equal at all times to the market value of the securities loaned. The Fund
may bear the risk of delay in recovery of, or loss of rights in, the securities
loaned should the borrower of the securities experience financial difficulty.
The Fund receives compensation for lending its securities in the form of fees or
it retains a portion of interest on the investment of any cash received as
collateral. The Fund also continues to receive interest and dividends on the
securities loaned and any gain or loss in the market price of the securities
loaned that may occur during the term of the loan will be for the account of the
Fund. (See Note 7.)

(D) LOAN PARTICIPATIONS AND COMMITMENTS.  The Fund invests in loan
participations. Loan participations are agreements to make money available (a
"commitment") to a borrower in a specified amount, at a specified rate and
within a specified time. Such loan participations are typically senior, secured
and collateralized in nature. The Fund records an investment when the borrower
withdraws money and records interest as earned. These loans pay interest at
rates which are periodically reset by reference to a base lending rate plus a
spread. These base lending rates are generally the prime rate offered by a
designated U.S. bank or London InterBank Offered Rate (LIBOR).

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

The Fund assumes the credit risk of the Borrower, the Selling Participant and
any other persons interpositioned between the Fund and the Borrower
("Intermediate Participants"). In the event that the Borrower, Selling
Participant or Intermediate Participants becomes insolvent or enters into
bankruptcy, the Fund may incur certain costs and delays in realizing payment, or
may suffer a loss of principal and/or interest.

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

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

(F) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are
recorded on the ex-dividend date. The Fund intends to declare and pay dividends
monthly and capital gain distributions, if any, annually. 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.

The following table discloses the current year reclassifications between
undistributed net investment income and accumulated net realized gain on
investments arising from permanent differences; net assets at October 31, 2004,
are not affected.

          $12,613        $(12,613)
</Table>

The reclassifications for the Fund are primarily due to premium amortization
adjustments, foreign currency gain (loss), and taxable over distributions of
dividends.

(G) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  The Fund records security
transactions on the trade date. Realized gains and losses on security
transactions are determined using the identified cost method. Interest income is
accrued as earned. Discounts and

                                                    www.mainstayfunds.com     21

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

premiums on securities, other than short-term securities, purchased for the Fund
are accreted and amortized, respectively, on the constant yield method over the
life of the respective securities, or, if applicable, 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
the 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.

(H) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred except where direct allocations of expenses can be made. Expenses
(other than expenses incurred under the distribution plans) are allocated to
separate classes of shares based upon their relative net asset value on the date
the expenses are incurred. The expenses borne by the Fund, including those of
related parties to the Fund, are shown in the Statement of Operations.

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

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

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

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

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

(J) 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.

Certain amounts have been reclassified to conform to current year presentation.
Such reclassifications had no effect on the Fund's net income or capital.

NOTE 3 -- FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER AND SUBADVISOR.  New York Life Investment Management LLC ("NYLIM" or
the "Manager"), an indirect wholly-owned subsidiary of New York Life Insurance
Company ("New York Life"), serves as the Fund's Manager. The Manager provides
offices, conducts clerical, recordkeeping and bookkeeping services, and keeps
the financial and accounting records required for the Fund. The Manager also
pays the salaries and expenses of all personnel affiliated with the Fund and all
the operational expenses that are not the responsibility of the Fund. MacKay
Shields LLC (the "Subadvisor"), a registered investment advisor and indirect
wholly-owned subsidiary of New York Life, is responsible for the day-to-day
portfolio management of the Fund.

Prior to July 31, 2004, the Trust, on behalf of the Fund, paid the Manager a
monthly fee for services performed and the facilities furnished at an annual
rate of 0.70% of the Fund's average daily net assets. The Manager had
voluntarily agreed to reimburse the expenses of the Fund to the extent that
operating expenses would exceed on an annualized basis 1.70%, 2.45% and 2.45% of
the average daily net assets of the Class A, Class B and Class C shares,
respectively. Effective August 1, 2004, the Trust pays the Manager an annual
rate of 0.70% of the Fund's average daily net assets on assets up to $500
million and 0.65% on assets over $500 million. In addition, effective December
1, 2004, NYLIM has voluntarily agreed to reimburse the expenses of the Fund to
the extent that operating expenses would exceed on an annualized basis 1.51%,
2.26% and 2.26% of the average daily net assets of the Class A, Class B and
Class C shares, respectively. For the year ended October 31, 2004, the Manager
earned from the Fund $578,715. It was not necessary for the Manager to reimburse
the Fund for expenses for the year ended October 31, 2004.

Pursuant to the terms of a Sub-Advisory Agreement between NYLIM and MacKay
Shields, the Manager paid the Subadvisor a monthly fee at an annual rate of
0.35% of the average daily net assets of the Fund. To the extent that the
Manager has agreed to voluntarily reduce its fee, the Subadvisor has voluntarily
agreed to do so proportionately.

(B) DISTRIBUTION AND SERVICE FEES.  The Trust, on behalf of the Fund, has a
Distribution Agreement with NYLIFE Distributors LLC (the "Distributor"), an
indirect wholly-owned subsidiary of New York Life. The Fund, with respect to
each class of shares, has adopted distribution

 22   MainStay Global High Income Fund


plans (the "Plans") in accordance with the provisions of Rule 12b-1 under the
1940 Act. Pursuant to the Class A Plan, the Distributor receives a monthly fee
from the Fund at an annual rate of 0.25% of the average daily net assets of the
Fund's Class A shares, which is an expense of the Class A shares of the Fund for
distribution or service activities as designated by the Distributor. Pursuant to
the Class B and Class C Plans, the Fund pays the Distributor a monthly fee,
which is an expense of the Class B and Class C shares of the Fund, at the annual
rate of 0.75% of the average daily net assets of the Fund's Class B and Class C
shares. The distribution plans provide that the Class B and Class C shares of
the Fund 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 Fund.

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

(C) SALES CHARGES.  The Fund was advised by the Distributor that the amount of
sales charges retained on sales of Class A shares was $26,409 for the year ended
October 31, 2004. The Fund was also advised that the Distributor retained
contingent deferred sales charges on redemptions of Class A, Class B and Class C
shares of $258, $55,986 and $7,167 respectively, for the year ended October 31,
2004.

Service Company LLC ("NYLIM Service"), an affiliate of New York Life Investment
Management LLC, is the Fund's transfer, dividend disbursing and shareholder
servicing agent. NYLIM Service has entered into an agreement with Boston

the services for which NYLIM Service is responsible. Transfer agent expenses for
the year ended October 31, 2004 amounted to $249,442.

(E) NON-INTERESTED TRUSTEES.  Non-Interested Trustees are paid an annual
retainer fee of $45,000, $2,000 for each Board meeting, $1,000 for each

$20 million of average monthly net assets, 1/30 of 1% of the next $80 million of
average monthly net assets and 1/100 of 1% of any amount in excess of $100
million of average monthly net assets. Fees for recordkeeping services provided
to the Fund by the Manager amounted to $30,899 for the year ended October 31,
2004.

NOTE 4 -- CUSTODIAN:

NOTE 5 -- RESTRICTED SECURITIES:

A restricted security is a security which has been purchased through a private
offering and cannot be resold to the general public without prior registration
under the Securities Act of 1933 (the "1933 Act"). The Fund does not have the
right to demand that such securities be registered. Disposal of these securities
may involve time-consuming negotiations and expense, and prompt sale at an
acceptable price may be difficult.

NOTE 11 -- OTHER MATTERS:

NYLIM and mutual funds that NYLIM advises have received requests for information
from various government authorities and regulatory bodies regarding market
timing, late trading, operations, fees, expenses, and other matters. NYLIM and
the funds it advises are cooperating fully in responding to these requests. As
reported in response to those requests for information, NYLIM was previously
party to agreements with certain registered representatives of broker-dealers
relating to the level of trading by clients or customers of those registered
representatives in shares of certain funds of the Trust. NYLIM is continuing to
review what effect, if any, transactions under these agreements may have had on
the funds, and will continue to apprise the Board of Trustees of such
information. NYLIM does not believe at this time that such trading had any
material effect on the funds' financial statements or their shareholders. To
date, substantially all of the costs associated with these and other regulatory
matters have been borne by NYLIM. Except as described below, neither NYLIM nor
the funds advised by it have any reason to believe that they have been targeted
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.
Discussions have been held with the SEC concerning a possible resolution of this
matter. These discussions are continuing, but there can be no assurance at this
time as to the outcome of these efforts.

NOTE 12 -- CHANGE IN INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM (UNAUDITED):

On March 8, 2004, KPMG LLP ("KPMG") was selected as the Trust's independent
auditor for the 2004 fiscal year. The selection of KPMG was recommended by the
Trust's Audit Committee, comprised of all Non-Interested Trustees, and was
approved by the Trust's Board of Trustees.

The predecessor independent auditor's reports on the Trust's financial
statements for the period ended October 31, 2003 and year ended December 31,
2002 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 periods, and through the date of engagement of KPMG, there
were no disagreements between 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 periods.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Trustees and Shareholders of
The MainStay Funds:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of the MainStay Global High Income Fund (the
"Fund"), one of the funds constituting The MainStay Funds, as of October 31,
2004, and the related statement of operations, statement of changes in net
assets and the financial highlights for the year then ended. These financial
statements and financial highlights are the responsibility of the Fund's
management. Our responsibility is to express an opinion on these financial
statements and financial highlights based on our audit. The statement of changes
in net assets for the period ended October 31, 2003 and the year ended December
31, 2002, and the financial highlights for the periods presented through October
31, 2003, were audited by other auditors, whose report dated December 18, 2003
expressed an unqualified opinion thereon.

We conducted our audit in accordance with the Standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
also includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2004 by correspondence with the custodian and
brokers. As to securities purchased or sold but not yet received or delivered,
we performed other appropriate auditing procedures. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
MainStay Global High Income Fund of The MainStay Funds as of October 31, 2004,
the results of its operations, the changes in its net assets and its financial
highlights for the year then ended, in conformity with U.S. generally accepted
accounting principles.

 2   MainStay Common Stock Fund


MESSAGE FROM
THE PRESIDENT

During the 12 months ended October 31, 2004, the U.S. stock market advanced, but
its pace and direction were by no means steady. Small- and mid-capitalization
stocks tended to outperform large-cap issues, and value stocks generally
outperformed growth stocks.

Economic activity, as measured by gross domestic product, increased from 4.2% in
the fourth quarter of 2003 to 4.5% in the first quarter of 2004. The pace of
economic growth slowed to 3.3% in the second quar-
ter of 2004, and according to preliminary estimates from the Bureau of Economic
Analysis, gross domestic product grew at a seasonally adjusted annual rate of
3.9% in the third quarter of 2004.

Interest rates began the reporting period at a low 1.00%. In June 2004, the
Federal Open Market Committee responded to expanding output and improved labor
markets by raising the targeted federal funds rate by 25 basis points. Similar
moves in August and September brought the targeted federal funds rate to 1.75%.
In its September 2004 release, the Federal Open Market Committee affirmed its
belief that monetary policy remained accommodative.

Despite rising interest rates, bond markets generally advanced. High-yield bonds
and emerging-market debt were particularly strong. The U.S. dollar declined
relative to most other currencies, which helped U.S. exporters.

In pursuing its investment objective, each MainStay Fund consistently seeks to
apply a well-defined investment process in all market environments. We believe
that a consistent, disciplined investment approach can help investors make more
prudent and practical decisions regarding their investments.

In the report that follows, you'll find additional information about the market
forces, investment decisions, and individual securities that affected your
MainStay Fund during the 12 months ended October 31, 2004. We thank you for
investing with us, and we look forward to many years of continued service in
your behalf.
Sincerely,

/s/ GARY E. WENDLANDT

Gary E. Wendlandt

President

Performance tables and graphs do not reflect the deduction of taxes that a
shareholder would pay on distributions or Fund-share redemptions. Total returns
reflect change in share price, reinvestment of dividend and capital-gain
distributions, and maximum applicable sales charges explained in this paragraph.
The graphs assume an initial investment of $10,000 and reflect the deduction of
all sales charges that would have applied for the period of investment. Class A
shares are sold with a maximum initial sales charge of 5.5% and an annual 12b-1
fee of .25%. Class B shares are sold with no initial sales charge, are subject
to a contingent deferred sales charge (CDSC) of up to 5% if redeemed within the
first six years of purchase, and have an annual 12b-1 fee of 1.00%. Class C
shares are sold with no initial sales charge, are subject to a CDSC of 1% if
redeemed within one year of purchase, and have an annual 12b-1 fee of 1.00%.
Performance figures reflect certain fee waivers and/or expense limitations,
without which total returns may have been lower. The fee waivers and/or expense
limitations are voluntary and may be discontinued at any time. From inception

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

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 data 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

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

The Fund underwent several changes during the reporting period. The Fund changed
its name from MainStay Growth Opportunities Fund to MainStay Common Stock Fund
as of January 1, 2004. Then, on March 1, 2004, a new portfolio manager was
assigned to the Fund. The former portfolio management team used a fundamental
stock-picking investment strategy and invested in approximately 100 stocks. As
the new portfolio manager, we use a quantitative factor-based model,
supplemented by bottom-up stock selection. The Fund now invests in approximately
500 stocks. The Fund continues to be measured against the S&P 500(R) Index.(1)
There was no change to the Fund's investment objective of seeking long-term
growth of capital, with income as a secondary consideration.

CAN YOU DESCRIBE THE FUND'S NEW INVESTMENT APPROACH IN MORE DETAIL?

The Fund normally invests at least 80% of its assets in common stocks of
well-established, well-managed U.S. companies that appear to have better-than-
average potential for capital appreciation and that have large- to mid-cap
market capitalizations. We seek to identify companies that are considered to
represent good value based on historical investment standards, including
price/book value ratios and price/earnings ratios. We manage the Fund with a
core orientation, including growth and value equities, determined by market
conditions. In employing our bottom-up approach, we assess stocks based on their
individual strengths, rather than focusing on the underlying sectors or
industries of those stocks or on general economic trends. We may sell a stock
if--based on economic conditions, changes in the issuer's financial condition,
changes in the issuer's industry, or other considerations--we do not believe
that the security will help the Fund meet its investment objective.

WHICH SECTORS MADE THE BIGGEST CONTRIBUTIONS TO THE FUND'S PERFORMANCE DURING
THE 12 MONTHS ENDED OCTOBER 31, 2004?

The health care, materials, and energy sectors made the largest positive
contributions to the Fund's performance.

WHICH SECURITIES WERE STRONG PERFORMERS IN THE HEALTH CARE SECTOR?

The Fund's overweighted position in Boston Scientific proved beneficial, as the
company's earnings continued to surge despite the summer recall of some of its
Taxus drug-coated stents. Indeed, the medical-device company more than doubled
its profits in the third calendar quarter of 2004, beating Wall Street's
expectations. Taxus, a recently approved coronary stent, is coated with special
drugs designed to reduce the risk that arteries will reclose after angioplasty.
The device is expected to challenge Johnson & Johnson's market share in the
drug-coated stent market.

The Fund's overweighted position in managed-care provider Aetna also
strengthened performance, as the company's earnings rose in the first, second,
and third quarters of 2004. Each quarter's results reflected higher revenues,
based on increased fees, premiums, and medical-plan membership, as well as
reduced costs and greater efficiencies. Aetna's third-quarter results were
further buoyed by a one-time tax refund related to discontinued unprofitable
operations.

The Fund's overweighted position in Guidant helped the Fund's 12-month
performance, as the company's share price rose following positive test results
for its experimental drug-coated arterial stent that may rival those currently
available from Boston Scientific and Johnson & Johnson. The company also stands
to benefit from new Medicare coverage of implantable cardiac defibrillators.
These devices currently account for half of the company's business.

WHICH SECURITIES HELPED PERFORMANCE IN THE MATERIALS SECTOR?

The Fund's overweighted position in Phelps Dodge, the world's second-largest
copper producer, provided favorable results. The company posted solid third-
quarter 2004 earnings as a result of strong demand from China, limited copper
supply, and lower costs for copper production. A similarly overweighted position
in Eastman Chemical also contributed positively to the Fund's return, as the
company handily beat analysts' expectations in the third calendar quarter.

WHAT ABOUT ENERGY STOCKS?

The Fund's overweighted positions in oil companies ConocoPhillips, Devon Energy,
and Valero helped relative results. These stocks surged over the 12-month
period, as oil prices reached unprecedented levels. ConocoPhillips also
benefited from its

                                                     www.mainstayfunds.com     7


successful bid on a stake in Russia's largest oil company, Lukoil. This
investment should boost ConocoPhillips' exposure to the higher-growth and
higher-returning Russian and Iraqi oil markets. Indeed, the company reported a
54% increase in third-quarter 2004 profits, as income from its exploration and
production operations advanced against a backdrop of higher crude oil prices.
Valero, the nation's largest independent oil refiner, experienced stellar
results based on both strong demand and widening spreads between sweet and sour
crude oil prices.

WHICH SECTORS DETRACTED FROM THE FUND'S PERFORMANCE DURING THE REPORTING PERIOD?

The positive contributions we've already discussed were not enough to offset the
negative results from holdings in the information technology and consumer
staples sectors.

WHICH INFORMATION TECHNOLOGY SECTOR HOLDINGS HURT THE FUND'S RELATIVE
PERFORMANCE?

The Fund's overweighted position in Texas Instruments detracted from
performance. The company's share price continued to decline into the third
quarter of 2004. The stock suffered when Texas Instruments warned that sales
could fall below original forecasts if customers trim inventory levels to
reflect slower growth rates for end products. The Fund's underweighted position
in Yahoo! also hurt relative performance, since the Internet powerhouse's stock
price advanced on strong profit growth. Yahoo!'s third-quarter 2004 profits
nearly quadrupled compared to the same period last year. A $191 million pre-tax
gain from selling part of the company's stake in rival Internet search engine
Google helped, but even without this gain, the company would have nearly doubled
its earnings for the quarter.

WHICH CONSUMER STAPLES STOCKS DETRACTED FROM THE FUND'S PERFORMANCE?

The Fund's underweighted position in tobacco concern Altria hurt relative
performance, as the company's valuation increased almost 10% for the year.(2)
Altria experienced a solid first quarter 2004 based on rising domestic and
international sales of its tobacco brand leader, Marlboro. Philip Morris
represents about three-fifths of Altria's revenues. The company then experienced
modestly higher results in the second quarter as the U.S. dollar weakened and
tax rates declined. Altria's third-quarter earnings rose approximately 6%,
primarily as a result of a higher profit contribution from overseas beer brewer
SABMiller, where Altria holds a 36% minority interest.

Finally, an overweighted position in Avon detracted from the Fund's 12-month
performance. The company's stock tumbled on sluggish domestic sales, especially
in color cosmetics, children's apparel, and toys.

WHAT DO YOU ANTICIPATE GOING FORWARD?

The recent Bush presidential victory served as a short-term catalyst for a surge
in the equity markets. It remains to be seen, however, whether the direction of
oil prices, the pace of interest rate hikes, the rate of inflation, the relative
weakness of the U.S. dollar, the burgeoning current account deficit, and the
potential effects of these dynamics on corporate earnings will quell some of the
market's anxieties or exacerbate them.

We continue to believe that large-cap equities may offer solid investment
opportunities, even in highly volatile and unpredictable markets. Our
disciplined, quantitative model-based investment approach will continue to seek
promising stocks of established companies that we believe represent good value
and appear to have better-than-average potential for capital appreciation
without regard to market psychology or other subjective factors.

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

NOTES TO FINANCIAL STATEMENTS

NOTE 1 -- ORGANIZATION AND BUSINESS:

The MainStay Funds (the "Trust") was organized on January 9, 1986 as a
Massachusetts business trust. The Trust is registered under the Investment
Company Act of 1940, as amended (the "1940 Act"), as an open-end management
investment company and is comprised of twenty-two funds (collectively referred
to as the "Funds"). These financial statements and notes relate only to MainStay
Common Stock Fund (the "Fund"), a diversified fund.

The Fund currently offers three classes of shares. Beginning December 28, 2004,
the Fund will also offer Class I shares. Distribution of Class A shares and
Class B shares commenced on June 1, 1998. Class C shares were initially offered
on September 1, 1998. 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 within one year of purchase of Class C
shares. Class A shares, Class B shares and Class C shares bear the same voting
(except for issues that relate solely to one class), dividend, liquidation and
other rights and conditions except that the Class B shares and Class C shares
are subject to higher distribution fee rates. Each class of shares bears
distribution and/or service fee payments under a distribution plan pursuant to
Rule 12b-1 under the 1940 Act.

The Fund's investment objective is to seek long-term growth of capital, with
income as a secondary consideration.

Effective January 1, 2004, the Fund changed its name to MainStay Common Stock
Fund from MainStay Growth Opportunities Fund.

NOTE 2 -- SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with generally accepted
accounting principles and follows the significant accounting policies described
below.
(A) SECURITIES VALUATION.  Equity securities are valued at the latest quoted
sales prices as of the close of 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. 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.
Securities for which market quotations are not readily available are valued by
methods deemed by the Board of Trustees to represent fair value. Reasons for
which securities may be valued in this manner include, but are not limited to,
trading for a security has been halted or suspended, a security has been
de-listed from a national exchange, or trading on a security's primary market is
temporarily closed at a time when under normal conditions it would be open. The
Fund did not hold securities at October 31, 2004, that were valued in such
manner.

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

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

(C) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are
recorded on the ex-dividend date. The Fund intends to declare and pay any
dividends quarterly and capital gain distributions, if any, annually. 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.

The following table discloses the current period reclassification between
accumulated net investment loss, accumulated net realized loss on investments
and additional paid-in capital arising from permanent differences; net assets at
October 31, 2004, are not affected.

<Table>
<Caption>
   ACCUMULATED        ACCUMULATED
  NET INVESTMENT   NET REALIZED LOSS     ADDITIONAL
       LOSS         ON INVESTMENTS     PAID-IN-CAPITAL
                                 

     $482,199           $45,141          $(527,340)
  ----------------------------------------------------
</Table>

The reclassifications for the Fund is primarily due to the fact that net
operating losses cannot be carried forward for federal income tax purposes and
real estate investment trusts investments.

(D) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  The Fund records security
transactions on the

 22   MainStay Common Stock Fund


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

(E) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred except where direct allocations of expenses can be made. Expenses
(other than expenses incurred under the distribution plans) are allocated to
separate classes of shares based upon their relative net asset value on the date
the expenses are incurred. The expenses borne by the Fund, including those of
related parties to the Fund, are shown in the Statement of Operations.

(F) USE OF ESTIMATES.  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.

NOTE 3 -- FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER.  New York Life Investment Management LLC ("NYLIM" or the
"Manager"), an indirect wholly-owned subsidiary of New York Life, serves as the
Fund's Manager. The Manager provides offices, conducts clerical, recordkeeping
and bookkeeping services, and keeps the financial and accounting records
required for the Fund. The Manager also pays the salaries and expenses of all
personnel affiliated with the Fund and all the operational expenses that are not
the responsibility of the Fund. The Fund is advised by the Manager directly,
without a Subadvisor.

Through July 31, 2004, the Trust, on behalf of the Fund, paid the Manager a
monthly fee for services performed and the facilities furnished at an annual
rate of 0.70% of the Fund's average daily net assets. The Manager had
voluntarily agreed to reimburse the expenses of the Fund to the extent that
operating expenses would exceed on an annualized basis 1.65%, 2.40% and 2.40% of
the average daily net assets of the Class A, Class B and Class C shares,
respectively. Effective August 1, 2004, the Trust pays the Manager an annual
rate of 0.70% of the Fund's average daily net assets on assets up to $500
million and 0.65% on assets over $500 million. In addition, effective December
1, 2004, NYLIM has voluntarily agreed to reimburse the expenses of the Fund to
the extent that operating expenses would exceed on an annualized basis 1.38%,
2.13% and 2.13% of the average daily net assets of the Class A, Class B and
Class C shares, respectively. For the year ended October 31, 2004, the Manager
earned from the Fund $655,095 and reimbursed the Fund for $110,333.

(B) DISTRIBUTION AND SERVICE FEES.  The Trust, on behalf of the Fund, has a
Distribution Agreement with NYLIFE Distributors LLC ("the Distributor"), an
indirect wholly-owned subsidiary of New York Life. The Fund, with respect to
each class of shares, has adopted distribution plans (the "Plans") in accordance
with the provisions of Rule 12b-1 under the 1940 Act. Pursuant to the Class A
Plan, the Distributor receives a monthly fee from the Fund at an annual rate of
0.25% of the average daily net assets of the Fund's Class A shares, which is an
expense of the Class A shares of the Fund for distribution or service activities
as designated by the Distributor. Pursuant to the Class B and Class C Plans, the
Fund pays the Distributor a monthly fee, which is an expense of the Class B and
Class C shares of the Fund, at the annual rate of 0.75% of the average daily net
assets of the Fund's Class B and Class C shares. The Distribution Plans provide
that the Class B and Class C shares of the Fund 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 Fund.

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

(C) SALES CHARGES.  The Fund was advised by the Distributor that the amount of
sales charges retained on sales of Class A shares was $8,993 for the year ended
October 31, 2004. The Fund was also advised that the Distributor retained
contingent deferred sales charges on redemptions of Class A, Class B and Class C
shares of $336, $63,300 and $396, respectively, for the year ended October 31,
2004.

(D) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT.  NYLIM
Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's
transfer, dividend disbursing and shareholder servicing agent. NYLIM Service has
entered into an agreement with Boston Financial Data Services ("BFDS") pursuant
to which BFDS will perform certain of the services for which NYLIM Service is
responsible. Transfer agent expenses for the year ended October 31, 2004,
amounted to $522,874.

(E) NON-INTERESTED TRUSTEES FEES.  Non-Interested Trustees are paid an annual
retainer fee of $45,000, $2,000 for each Board meeting, $1,000 for each
Committee meeting and $500 for each Valuation Subcommittee telephonic meeting
attended plus reimbursement for travel and out-of-pocket expenses. The Lead
Non-Interested Trustee is also paid an annual retainer fee of $20,000. The Audit

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

Committee Chairman receives an additional $2,000 for each meeting of the Audit
Committee attended and the Chairpersons of the Brokerage Committee, Operations
Committee and Performance Committee each receive an additional $1,000 for each
meeting of the Brokerage Committee, Operations Committee and Performance
Committee attended, respectively. In addition, each Non-Interested Trustee is
paid $1,000 for attending meetings of the Non-Interested Trustees held in
advance of or in connection with Board/Committee meetings. The Trust allocates
trustees fees in proportion to the net assets of the respective Funds. Thus the
Common Stock Fund only pays a portion of the fees identified above.

(F) CAPITAL.  At October 31, 2004, New York Life held shares of Class A with a
value of $11,060,591. This represents 31.6% of the Class A net assets and 12.1%
of the Fund's total net assets at year end.

(G) OTHER.  Fees for the cost of legal services, included in Professional fees,
as shown on the Statement of Operations, provided to the Fund by the Office of
the General Counsel of NYLIM amounted to $2,797 for the year ended October 31,
2004.

The Fund pays the Manager a monthly fee for recordkeeping services provided
under the Accounting Agreement at the annual rate of 1/20 of 1% for the first
$20 million of average monthly net assets, 1/30 of 1% of the next $80 million of
average monthly net assets and 1/100 of 1% of any amount in excess of $100
million of average monthly net assets. Fees for recordkeeping services provided
to the Fund by the Manager amounted to $34,528 for the year ended October 31,
2004.

NOTE 4 -- CUSTODIAN:

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

NOTE 5 -- FEDERAL INCOME TAX:

As of October 31, 2004, the components of accumulated loss on a tax basis were
as follows:

<Table>
<Caption>
  ACCUMULATED CAPITAL    UNREALIZED    TOTAL ACCUMULATED
   AND OTHER LOSSES     APPRECIATION         LOSS
                                 
     $(19,609,695)       $2,147,593      $ (17,462,102)
  ------------------------------------------------------
</Table>

The difference between book-basis and tax-basis unrealized appreciation is
primarily due to wash sale deferrals.

At October 31, 2004, for federal income tax purposes, capital loss carryforwards
of $19,609,695 were available as shown in the table below, to the extent
provided by the regulations, to offset future realized gains 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 6 -- PURCHASES AND SALES OF SECURITIES (IN 000'S):

During the year ended October 31, 2004, purchases and sales of securities, other
than short-term securities, were $127,199 and $134,494, respectively.

NOTE 7 -- LINE OF CREDIT:

The Fund and certain affiliated funds maintain a line of credit of $160,000,000
with a syndicate of banks in order to secure a source of funds for temporary
purposes to meet unanticipated or excessive shareholder redemption requests. The
funds pay a commitment fee, at an annual rate of .075% of the average commitment
amount, regardless of usage, to The Bank of New York, which acts as agent to the
syndicate. Such commitment fees are allocated among the funds based upon net
assets and other factors. Interest on any revolving credit loan is charged based
upon the Federal Funds Advances rate. There were no borrowings on the line of
credit during the year ended October 31, 2004.

NOTE 9 -- OTHER MATTERS:

NYLIM and mutual funds that NYLIM advises have received requests for information
from various government authorities and regulatory bodies regarding market
timing, late trading, operations, fees, expenses, and other matters. NYLIM and
the funds it advises are cooperating fully in responding to these requests. As
reported in response to those requests for information, NYLIM was previously
party to agreements with certain registered representatives of broker-dealers
relating to the level of trading by clients or customers of those registered
representatives in shares of certain funds of the Trust. NYLIM is continuing to
review what effect, if any, transactions under these agreements may have had on
the funds, and will continue to apprise the Board of Trustees of such
information. NYLIM does not believe at this time that such trading had any
material effect on the funds' financial statements or their shareholders. To
date, substantially all of the costs associated with these and other regulatory
matters have been borne by NYLIM. Except as described below, neither NYLIM nor
the funds advised by it have any reason to believe that they have been targeted
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.
Discussions have been held with the SEC concerning a possible resolution of this
matter. These discussions are continuing, but there can be no assurance at this
time as to the outcome of these efforts.

NOTE 10 -- CHANGE IN INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM (UNAUDITED):

On March 8, 2004, KPMG LLP ("KPMG") was selected as the Trust's independent
auditor for the 2004 fiscal year. The selection of KPMG was recommended by the
Trust's Audit Committee, comprised of all Non-Interested Trustees, and was
approved by the Trust's Board of Trustees.

The predecessor independent auditor's reports on the Trust's financial
statements for the period ended October 31, 2003 and year ended December 31,
2002 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 periods, and through the date of engagement of KPMG, there
were no disagreements between 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 periods.

                                                    www.mainstayfunds.com     25


REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Trustees and Shareholders of
The MainStay Funds:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of the MainStay Common Stock Fund (the "Fund"),
one of the funds constituting The MainStay Funds, as of October 31, 2004, and
the related statement of operations, statement of changes in net assets and the
financial highlights for the year then ended. These financial statements and
financial highlights are the responsibility of the Fund's management. Our
responsibility is to express an opinion on these financial statements and
financial highlights based on our audit. The statement of changes in net assets
for the period ended October 31, 2003 and the year ended December 31, 2002, and
the financial highlights for the periods presented through October 31, 2003,
were audited by other auditors, whose report dated December 18, 2003 expressed
an unqualified opinion thereon.

We conducted our audit in accordance with the Standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
also includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2004 by correspondence with the custodian and
brokers. As to securities purchased or sold but not yet received or delivered,
we performed other appropriate auditing procedures. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
MainStay Common Stock Fund of The MainStay Funds as of October 31, 2004, the
results of its operations, the changes in its net assets and its financial
highlights for the year then ended, in conformity with U.S. generally accepted
accounting principles.

                    Annual Report

                    October 31, 2004


MESSAGE FROM
THE PRESIDENT

During the 12 months ended October 31, 2004, the U.S. stock market advanced, but
its pace and direction were by no means steady. Small- and mid-capitalization
stocks tended to outperform large-cap issues, and value stocks generally
outperformed growth stocks.

Economic activity, as measured by gross domestic product, increased from 4.2% in
the fourth quarter of 2003 to 4.5% in the first quarter of 2004. The pace of
economic growth slowed to 3.3% in the second quar-
ter of 2004, and according to preliminary estimates from the Bureau of Economic
Analysis, gross domestic product grew at a seasonally adjusted annual rate of
3.9% in the third quarter of 2004.

Interest rates began the reporting period at a low 1.00%. In June 2004, the
Federal Open Market Committee responded to expanding output and improved labor
markets by raising the targeted federal funds rate by 25 basis points. Similar
moves in August and September brought the targeted federal funds rate to 1.75%.
In its September 2004 release, the Federal Open Market Committee affirmed its
belief that monetary policy remained accommodative.

Despite rising interest rates, bond markets generally advanced. High-yield bonds
and emerging-market debt were particularly strong. The U.S. dollar declined
relative to most other currencies, which helped U.S. exporters.

In pursuing its investment objective, each MainStay Fund consistently seeks to
apply a well-defined investment process in all market environments. We believe
that a consistent, disciplined investment approach can help investors make more
prudent and practical decisions regarding their investments.

In the report that follows, you'll find additional information about the market
forces, investment decisions, and individual securities that affected your
MainStay Fund during the 12 months ended October 31, 2004. We thank you for
investing with us, and we look forward to many years of continued service in
your behalf.

Sincerely,
/s/ GARY E. WENDLANDT

Gary E. Wendlandt

President

Performance tables and graphs do not reflect the deduction of taxes that a
shareholder would pay on distributions or Fund-share redemptions. Total returns
reflect change in share price, reinvestment of dividend and capital-gain
distributions, and maximum applicable sales charges explained in this paragraph.
The graphs assume an initial investment of $10,000 and reflect the deduction of
all sales charges that would have applied for the period of investment. Class A
shares are sold with a maximum initial sales charge of 5.5% and an annual 12b-1
fee of .25%. Class B shares are sold with no initial sales charge, are subject
to a contingent deferred sales charge (CDSC) of up to 5% if redeemed within the
first six years of purchase, and have an annual 12b-1 fee of 1.00%. Class C
shares are sold with no initial sales charge, are subject to a CDSC of 1% if
redeemed within one year of purchase, and have an annual 12b-1 fee of 1.00%.
Performance figures reflect certain fee waivers and/or expense limitations,
without which total returns may have been lower. The fee waivers and/or expense
limitations are voluntary and may be discontinued at any time. From inception
(6/1/98) through 8/31/98, performance for Class C shares (first offered 9/1/98)
includes the historical performance of Class B shares adjusted to reflect the
applicable CDSC for Class C shares.

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

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 data column of the table
is useful in comparing ongoing costs only and will not help you determine the

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

Questions answered by portfolio manager Joel Heymsfeld of Mercury Advisors

CAN YOU BRIEFLY DESCRIBE THE FUND'S INVESTMENT APPROACH?

The Fund invests primarily in common stocks and other securities with equity
characteristics, such as convertible debt, convertible preferred securities,
preferred stocks, and warrants and rights. The Fund may also invest in foreign
securities. In implementing this strategy, we follow a research-intensive,
value-oriented approach that focuses on securities that are deemed to be
undervalued and that appear to have favorable earnings growth prospects,
above-average return on equity and dividend yield, and solid financial
condition. Various qualitative factors may also be considered. Securities may be
sold when economic, financial, industry, or company factors suggest that the
securities will no longer contribute to meeting the Fund's investment objective.

WHAT MAJOR FACTORS INFLUENCED THE STOCK MARKET DURING THE 12 MONTHS ENDED
OCTOBER 31, 2004?

Continuing strength in the U.S. economy helped the stock market trend upward
from November 2003 through February 2004. After that, the market failed to make
additional net progress through the end of October. Strength in overall
corporate earnings remained a positive influence on share prices. Rising oil
prices, on the other hand, had a dampening effect on economic activity and also
raised concerns about a resurgence of inflation. Energy-related stocks were
market leaders, as the upward trend in oil prices helped keep energy-company
earnings above expectations.

Uncertainties over the outcome of the U.S. presidential election in November had
a negative impact on the stock market. This was particularly true for health
care stocks, which suffered from growing concern that the sector would be
vulnerable to a change in administration.

WHICH SECTORS HAD THE GREATEST IMPACT ON THE FUND'S PERFORMANCE DURING THE
12-MONTH REPORTING PERIOD?

Consumer discretionary, consumer staples, industrials, and financials were the
Fund's top-performing sectors relative to the Russell 1000(R) Value Index.(1) On
an absolute basis, the energy sector produced the highest return during the
12-month period. The Fund's positions in the health care sector took the
greatest toll on relative performance. An underweighted position in the utility
sector relative to the Russell 1000(R) Value Index also had a negative impact on
the Fund's results.

WHICH OF THE FUND'S HOLDINGS SHOWED STRONG PERFORMANCE DURING THE REPORTING
PERIOD?

Positions in the energy sector performed well, including ConocoPhillips
(+51%),(2) ChevronTexaco (+48%), and ExxonMobil (+38%). Retail holdings such as
J.C. Penney (+48%) and Limited Brands (+44%) also provided outstanding results.
Other strong performers included Archer-Daniels-Midland (+37%), Boeing (+32%),
Burlington Northern Santa Fe (+46%), and Xerox (+41%).

WHICH STOCKS UNDERPERFORMED?

Several health care holdings were weak, including Merck (-27%) and Bristol-Myers
Squibb (-18%). Other positions that detracted from performance included General
Motors (-19%) and Hewlett-Packard (-15%).

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

New positions for the Fund during the 12-month period included General Motors,
Viacom, Fannie Mae, and Lehman Brothers. General Motors had dramatically
improved its cost-control management, product quality, and product offerings.
Viacom offered one of the best balance sheets among media companies, and the
company was planning to use cash from its Blockbuster spin-off to repurchase a
substantial number of shares. We bought shares of Fannie Mae on expectations of
low double-digit earnings growth, expanding home ownership, and attractive
valuations. We were encouraged by a settlement between Fannie Mae and a
regulatory agency that was critical of the company's accounting practices.
Lehman Brothers is strengthening its position in investment banking and asset
management. We believe these improvements should augment the company's
already-strong positions the fixed-income markets and in trading.

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.

   Index.
2. Percentages reflect total returns of Fund holdings in the securities
   mentioned, including purchases and sales, for the 12 months ended 10/31/04,
   or for the portion of the reporting period such securities were held in the
   Fund, if shorter.

 6   MainStay Research Value Fund


During the reporting period, we sold the Fund's positions in Mattel, SBC
Communications, Burlington Northern Santa Fe, and Beckman Coulter. We sold
Mattel when weak demographics and a lack of purchasing power reinforced our
pessimistic outlook for the toy industry. We eliminated SBC Communications to
reduce the Fund's exposure to the telecommunications industry. We sold
Burlington Northern Santa Fe after its shares rose to a point where they
appeared to be fully valued relative to the company's earnings prospects. We
sold Beckman Coulter for similar reasons. We felt that after substantially
outperforming other health care holdings during the last several years, the
stock offered limited upside potential.

HOW DO THE FUND'S WEIGHTINGS DIFFER FROM THOSE OF THE S&P 500(R) INDEX?

Throughout the 12-month period, the Fund continued to maintain a meaningfully
underweighted position in the information technology sector, with a target of 9%
of assets relative to 17% for the S&P 500(R) Index.(3) The Fund's most
significantly overweighted sector during the reporting period was energy, with a
target weight of 9% versus 6% for the Index. The Fund reduced its exposure to
utilities and telecommunication services to positions that were nearly neutral
to the Index. With purchases of Fannie Mae and Lehman Brothers, the Fund moved
to a modestly overweighted position in the financials sector. The Fund was also
modestly overweighted relative to the S&P 500(R) in health care.

WHAT DO YOU ANTICIPATE GOING FORWARD?

We are increasingly optimistic about the U.S. equity market's prospects in the
coming months. The reelection of President Bush has effectively eliminated
election-year uncertainty, which we believe may have a favorable impact on share
prices. U.S. stocks may also benefit from evidence that inflation has remained
subdued and that economic growth may continue at a reasonable pace through 2005.
On balance, our longer-term view is also positive, as we continue to look for
average total investment returns for U.S. equities in the mid-to-high
single-digit range. We will continue to adhere to a disciplined, investment
approach guided by intensive fundamental research as we seek to identify
attractively valued companies for the Fund's portfolio.

MainStay Research Value Fund's portfolio manager changed effective May 17, 2004.
The Fund is still managed by Mercury Advisors, but its management team is now
led by Joel Heymsfeld.

At a meeting on September 21, 2004, the Board of Trustees of The MainStay Funds
(the "Trust") approved an Agreement and Plan of Reorganization whereby all of
the assets and liabilities of the Fund will be transferred to the MainStay Value
Fund (a series of the Trust) in exchange for shares of the MainStay Value Fund
(the "Reorganization"). Under this Agreement, the Fund would be completely
liquidated after the Reorganization. A meeting of shareholders of the Fund has
been scheduled for January 18, 2005 in order to vote on the proposed
Reorganization. Should shareholders approve a Reorganization, it is scheduled to
be effective on or about the close of business on January 21, 2005.

NOTES TO FINANCIAL STATEMENTS

NOTE 1 -- ORGANIZATION AND BUSINESS:

The MainStay Funds (the "Trust") was organized on January 9, 1986 as a
Massachusetts business trust. The Trust is registered under the Investment
Company Act of 1940, as amended (the "1940 Act"), as an open-end management
investment company and comprises twenty-two funds (collectively referred to as
the "Funds"). These financial statements and notes relate only to MainStay
Research Value Fund (the "Fund"), a diversified fund.

The Fund currently offers three classes of shares. Distribution of Class A
shares and Class B shares commenced on June 1, 1998. Class C shares were
initially offered on September 1, 1998. 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 within one year of purchase
of Class C shares. Class A shares, Class B shares and Class C shares bear the
same voting (except for issues that relate solely to one class), dividend,
liquidation and other rights and conditions except that the Class B shares and
Class C shares are subject to higher distribution fee rates. Each class of
shares bears distribution and/or service fee payments under a distribution plan
pursuant to Rule 12b-1 under the 1940 Act.

The Fund's investment objective is to seek long-term capital appreciation by
investing primarily in securities of large-capitalization companies.

NOTE 2 -- SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with generally accepted
accounting principles and follows the significant accounting policies described
below.

(A) SECURITIES VALUATION.  Equity securities are valued at the latest quoted
sales prices as of the close of 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. 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.
Securities for which market quotations are not readily available are valued by
methods deemed by the Board of Trustees to represent fair value. Reasons for
which securities may be valued in this manner include, but are not limited to,
trading for a security has been halted or suspended, a security has been
de-listed from a national exchange, or trading on a security's primary market is
temporarily closed at a time when under normal conditions it would be open. The
Fund did not hold securities at October 31, 2004, that were valued in such
manner.

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

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

(C) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are
recorded on the ex-dividend date. The Fund intends to declare and pay any
dividends quarterly and capital gain distributions, if any, annually. 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 Fund records security
transactions on the trade date. Realized gains and losses on security
transactions are determined using the identified cost method. Dividend income is
recognized on the ex-dividend date and interest income is accrued as earned.
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
the Fund are allocated to separate classes of shares based upon their relative
net assets on the date the income is earned or realized and unrealized gains and
losses are incurred.

(E) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred except where direct allocations of expenses can be made. Expenses
(other than expenses incurred under the distribution plan) are allocated to
separate classes of shares based upon their relative net asset value on the date
the expenses are incurred. The expenses borne by the Fund,

 14   MainStay Research Value Fund


including those of related parties to the Fund, are shown in the 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.

NOTE 3 -- FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER AND SUBADVISOR.  New York Life Investment Management LLC ("NYLIM" or
the "Manager"), an indirect wholly-owned subsidiary of New York Life Insurance
Company ("New York Life"), serves as the Fund's manager. The Manager provides
offices, conducts clerical, recordkeeping and bookkeeping services, and keeps
the financial and accounting records required for the Fund. The Manager also
pays the salaries and expenses of all personnel affiliated with the Fund and all
the operational expenses that are not the responsibility of the Fund. Fund Asset
Management, L.P., d/b/a Mercury Advisors ("Mercury" or the "Subadvisor") is
responsible for the day-to-day portfolio management of the Fund.

Through July 31, 2004, the Trust, on behalf of the Fund, paid the Manager a
monthly fee for services performed and the facilities furnished at an annual
rate of 0.85% of the Fund's average daily net assets. The Manager had
voluntarily agreed to reimburse the expenses of the Fund to the extent that
operating expenses would exceed on an annualized basis 1.70%, 2.45% and 2.45% of
the average daily net assets of the Class A, Class B and Class C shares,
respectively. Effective August 1, 2004, the Trust pays the Manager an annual
rate of 0.85% of the Fund's average daily net assets on assets up to $500
million and 0.80% on assets over $500 million. Also effective August 1, 2004,
NYLIM had voluntarily agreed to waive its management fee by 0.05% of the Fund's
average daily net assets. In addition, effective December 1, 2004, NYLIM has
voluntarily agreed to reimburse the expenses of the Fund to the extent that
operating expenses would exceed on an annualized basis 1.37%, 2.12% and 2.12% of
the average daily net assets of the Class A, Class B and Class C shares,
respectively. For the year ended October 31, 2004, the Manager earned from the
Fund $554,845, waived $7,998 and reimbursed the Fund $24,241. The fees waived
and reimbursed by the Manager total $32,239.

Pursuant to the terms of a Sub-Advisory Agreement between NYLIM and the
Subadvisor, the Manager paid the Subadvisor a monthly fee at an annual rate of
0.425% on assets up to $250 million, 0.3825% on assets from $250 million to $500
million and 0.34% on assets in excess of $500 million.

(B) DISTRIBUTION AND SERVICE FEES.  The Trust, on behalf of the Fund, has a
Distribution Agreement with NYLIFE Distributors LLC (the "Distributor"), an
indirect wholly-owned subsidiary of New York Life. The Fund, with respect to
each class of shares, has adopted distribution plans (the "Plans") in accordance
with the provisions of Rule 12b-1 under the 1940 Act. Pursuant to the Class A
Plan, the Distributor receives a monthly fee from the Fund at an annual rate of
0.25% of the average daily net assets of the Fund's Class A shares, which is an
expense of the Class A shares of the Fund for distribution or service activities
as designated by the Distributor. Pursuant to the Class B and Class C Plans, the
Fund pays the Distributor a monthly fee, which is an expense of the Class B and
Class C shares of the Fund, at the annual rate of 0.75% of the average daily net
assets of the Fund's Class B and Class C shares. The Distribution Plans provide
that the Class B and Class C shares of the Fund 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 Fund.

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

(C) SALES CHARGES.  The Fund was advised by the Distributor that the amount of
sales charges retained on sales of Class A shares was $4,934 for the year ended
October 31, 2004. The Fund was also advised that the Distributor retained
contingent deferred sales charges on redemption of Class A, Class B and Class C
shares of $640, $35,602 and $6,446, respectively, for the year ended October 31,
2004.

(D) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT.  NYLIM
Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's
transfer, dividend disbursing and shareholder servicing agent. NYLIM Service has
entered into an agreement with Boston Financial Data Services ("BFDS") pursuant
to which BFDS will perform certain of the services for which NYLIM Service is
responsible. Transfer agent expenses for the year ended October 31, 2004
amounted to $255,785.

(E) NON-INTERESTED TRUSTEES FEES.  Non-Interested Trustees are paid an annual
retainer fee of $45,000, $2,000 for each Board meeting, $1,000 for each
Committee meeting and $500 for each Valuation Subcommittee telephonic meeting
attended plus reimbursement for travel and out-of-pocket expenses. The Lead
Non-Interested Trustee is also paid an annual retainer fee of $20,000. The Audit
Committee Chairman receives an additional $2,000 for each meeting of the Audit
Committee attended and the Chairpersons of the Brokerage Committee, Operations
Committee and Performance Committee each receive an additional $1,000 for each
meeting of the Brokerage Committee, Operations Committee and Performance Com-

mittee attended, respectively. In addition, each Non-Interested Trustee is paid
$1,000 for attending meetings of the Non-Interested Trustees held in advance of
or in connection with Board/Committee meetings. The Trust allocates trustees
fees in proportion to the net assets of the respective Funds. Thus the Research
Value Fund only pays a portion of the fees identified above.

(F) CAPITAL.  At October 31, 2004, New York Life held shares of Class A with a
value of $11,412,216. This represents 45.9% of the net assets for Class A and
18.2% of the Fund's total net assets at year end.

(G) OTHER.  Fees for the cost of legal services, included in Professional fees
as shown on the Statement of Operations, provided to the Fund by the Office of
the General Counsel of NYLIM amounted to $1,938 for the year ended October 31,
2004.

The Fund pays the Manager a monthly fee for recordkeeping services provided
under the Accounting Agreement at the annual rate of 1/20 of 1% for the first
$20 million of average monthly net assets, 1/30 of 1% of the next $80 million of
average monthly net assets and 1/100 of 1% of any amount in excess of $100
million of average monthly net assets. Fees for recordkeeping services provided
to the Fund by the Manager amounted to $25,092 for the year ended October 31,
2004.

NOTE 4 -- CUSTODIAN:

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

NOTE 5 -- FEDERAL INCOME TAX:

As of October 31, 2004, the components of accumulated loss on a tax basis were
as follows:

<Table>
<Caption>
UNDISTRIBUTED   ACCUMULATED                      TOTAL
  ORDINARY      CAPITAL AND     UNREALIZED    ACCUMULATED

  $212,097      $(10,413,757)   $8,746,466    $(1,455,194)
</Table>

The difference between book-basis and tax-basis unrealized appreciation is due
to wash sale deferrals.

At October 31, 2004, for federal income tax purposes, capital loss carryforwards
of $10,413,757 were available, as shown in the table below, to offset future
realized gains of the 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.

The Fund utilized $5,280,224 of capital loss carryforward during the year ended
October 31, 2004.

The tax character of distributions paid during the year ended October 31, 2004,
the ten months ended October 31, 2003 and the year ended December 31, 2002,
shown in the Statement of Changes in Net Assets, was as follows:

NOTE 6 -- PURCHASES AND SALES OF SECURITIES (IN 000'S):

During the year ended October 31, 2004, purchases and sales of securities, other
than short-term securities, were $14,283 and $21,812, respectively.

NOTE 7 -- LINE OF CREDIT:

The Fund and certain affiliated funds maintain a line of credit of $160,000,000
with a syndicate of banks in order to secure a source of funds for temporary
purposes to meet unanticipated or excessive shareholder redemption requests. The
funds pay a commitment fee, at an annual rate of .075% of the average commitment
amount, regardless of usage, to The Bank of New York, which acts as agent to the
syndicate. Such commitment fees are allocated among the funds based upon net
assets and other factors. Interest on any revolving credit loan is charged based
upon the Federal Funds Advances rate. There were no borrowings on the line of
credit during the year ended October 31, 2004.

NOTE 9 -- SPECIAL MEETING OF SHAREHOLDERS:

The Board of Trustees of the Trust has called a Special Meeting of Shareholders
("Special Meeting") of the Fund, scheduled to be held on January 18, 2005. At
the Special Meeting, shareholders will vote on a proposed reorganization of the
Fund into the MainStay Value Fund, also a series of the Trust.

NOTE 10 -- OTHER MATTERS:

NYLIM and mutual funds that NYLIM advises have received requests for information
from various government authorities and regulatory bodies regarding market
timing, late trading, operations, fees, expenses, and other matters. NYLIM and
the funds it advises are cooperating fully in responding to these requests. As
reported in response to those requests for information, NYLIM was previously
party to agreements with certain registered representatives of broker-dealers
relating to the level of trading by clients or customers of those registered
representatives in shares of certain funds of the Trust. NYLIM is continuing to
review what effect, if any, transactions under these agreements may have had on
the funds, and will continue to apprise the Board of Trustees of such
information. NYLIM does not believe at this time that such trading had any
material effect on the funds' financial statements or their shareholders. To
date, substantially all of the costs associated with these and other regulatory
matters have been borne by NYLIM. Except as described below, neither NYLIM nor
the funds advised by it have any reason to believe that they have been targeted
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.
Discussions have been held with the SEC concerning a possible resolution of this
matter. These discussions are continuing, but there can be no assurance at this
time as to the outcome of these efforts.

NOTE 11 -- CHANGE IN INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM (UNAUDITED):

On March 8, 2004, KPMG LLP ("KPMG") was selected as the Trust's independent
auditor for the 2004 fiscal year. The selection of KPMG was recommended by the
Trust's Audit Committee, comprised of all Non-Interested Trustees, and was
approved by the Trust's Board of Trustees.

The predecessor independent auditor's reports on the Trust's financial
statements for the period ended October 31, 2003 and year ended December 31,
2002 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 periods, and through the date of engagement of KPMG, there
were no disagreements between 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 periods.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Trustees and Shareholders of
The MainStay Funds:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of the MainStay Research Value Fund (the "Fund"),
one of the funds constituting The MainStay Funds, as of October 31, 2004, and
the related statement of operations, statement of changes in net assets and the
financial highlights for the year then ended. These financial statements and
financial highlights are the responsibility of the Fund's management. Our
responsibility is to express an opinion on these financial statements and
financial highlights based on our audit. The statement of changes in net assets
for the period ended October 31, 2003 and the year ended December 31, 2002, and
the financial highlights for the periods presented through October 31, 2003,
were audited by other auditors, whose report dated December 18, 2003 expressed
an unqualified opinion thereon.

We conducted our audit in accordance with the Standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
also includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2004 by correspondence with the custodian and
brokers. As to securities purchased or sold but not yet received or delivered,
we performed other appropriate auditing procedures. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
MainStay Research Value Fund of The MainStay Funds as of October 31, 2004, the
results of its operations, the changes in its net assets and its financial
highlights for the year then ended, in conformity with U.S. generally accepted
accounting principles.

 2   MainStay Small Cap Growth Fund


MESSAGE FROM
THE PRESIDENT

During the 12 months ended October 31, 2004, the U.S. stock market advanced, but
its pace and direction were by no means steady. Small- and mid-capitalization
stocks tended to outperform large-cap issues, and value stocks generally
outperformed growth stocks.

Economic activity, as measured by gross domestic product, increased from 4.2% in
the fourth quarter of 2003 to 4.5% in the first quarter of 2004. The pace of
economic growth slowed to 3.3% in the second quar-
ter of 2004, and according to preliminary estimates from the Bureau of Economic
Analysis, gross domestic product grew at a seasonally adjusted annual rate of
3.9% in the third quarter of 2004.

Interest rates began the reporting period at a low 1.00%. In June 2004, the
Federal Open Market Committee responded to expanding output and improved labor
markets by raising the targeted federal funds rate by 25 basis points. Similar
moves in August and September brought the targeted federal funds rate to 1.75%.
In its September 2004 release, the Federal Open Market Committee affirmed its
belief that monetary policy remained accommodative.

Despite rising interest rates, bond markets generally advanced. High-yield bonds
and emerging-market debt were particularly strong. The U.S. dollar declined
relative to most other currencies, which helped U.S. exporters.

In pursuing its investment objective, each MainStay Fund consistently seeks to
apply a well-defined investment process in all market environments. We believe
that a consistent, disciplined investment approach can help investors make more
prudent and practical decisions regarding their investments.

In the report that follows, you'll find additional information about the market
forces, investment decisions, and individual securities that affected your
MainStay Fund during the 12 months ended October 31, 2004. We thank you for
investing with us, and we look forward to many years of continued service in
your behalf.
Sincerely,
/s/ GARY E. WENDLANDT
Gary E. Wendlandt

President

Performance tables and graphs do not reflect the deduction of taxes that a
shareholder would pay on distributions or Fund-share redemptions. Total returns
reflect change in share price, reinvestment of dividend and capital-gain
distributions, and maximum applicable sales charges explained in this paragraph.
The graphs assume an initial investment of $10,000 and reflect the deduction of
all sales charges that would have applied for the period of investment. Class A
shares are sold with a maximum initial sales charge of 5.5% and an annual 12b-1
fee of .25%. Class B shares are sold with no initial sales charge, are subject
to a contingent deferred sales charge (CDSC) of up to 5% if redeemed within the
first six years of purchase, and have an annual 12b-1 fee of 1.00%. Class C
shares are sold with no initial sales charge, are subject to a CDSC of 1% if
redeemed within one year of purchase, and have an annual 12b-1 fee of 1.00%.
From inception (6/1/98) through 8/31/98, performance for Class C shares (first
offered 9/1/98) includes the historical performance of Class B shares adjusted
to reflect the applicable CDSC for Class C shares.

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

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 data 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 Rudolph C. Carryl and Edmund C. Spelman
of MacKay Shields LLC

WHAT MAJOR FACTORS INFLUENCED THE STOCK MARKET DURING THE 12 MONTHS ENDED
OCTOBER 31, 2004?

The equity markets managed to register a healthy gain for the 12-month reporting
period, despite concerns over Federal Reserve interest-rate hikes, sharply
higher oil prices, an ongoing war in Iraq, and uncertainty surrounding the
outcome of the U.S. presidential election. Much of the market's advance took
place toward the end of the reporting period, when investors began to refocus on
those market fundamentals (such as earnings growth) that appeared to be
favorable.

CAN YOU BRIEFLY DESCRIBE THE FUND'S INVESTMENT APPROACH?

The Fund normally invests at least 80% of its assets in companies with market
capitalizations at the time of investment comparable to those of companies in
the Russell 2000(R) Index.(1) We select investments according to the economic
environment, and the attractiveness of particular markets, and the financial
condition and competitiveness of individual companies. In implementing this
strategy, we look for securities of companies with above-average revenue and
earnings per share growth, potential for positive earnings surprises, and strong
management. Ideally, the companies will have high levels of ownership by
insiders. We may also invest in companies that we believe are attractive because
of special factors, such as new management, new products, changes in consumer
demand, or changes in the economy. We may sell a stock if its fundamentals
deteriorate, if its valuation is deemed too high in relation to its growth rate
or its peer group, or if we no longer believe the security will help the Fund
meet its investment objective.

WHICH SECTORS HAD THE GREATEST IMPACT ON THE FUND'S PERFORMANCE DURING THE
12-MONTH REPORTING PERIOD?

During the year ended October 31, 2004, effective stock selection in consumer
staples, industrials, and information technology helped the Fund's performance
relative to the Russell 2000(R) Growth Index.(2) An underweighted position in
energy, however, detracted from the Fund's relative results, as the energy
sector rallied sharply with the rising price of oil. The Fund's underweighted
position in materials also detracted from performance.

WHAT WERE SOME OF THE FUND'S STOCK-SPECIFIC SUCCESS STORIES?

For the 12 months ended October 31, 2004, the greatest positive contributors to
the Fund's performance were FLIR Systems, Station Casinos, OSI Pharmaceuticals,
Cytyc, and VCA Antech. FLIR's earnings rose steadily on strong government and
commercial demand for the company's thermal imaging and infrared camera systems.
Station Casinos benefited from healthy demand from local Las Vegas citizens as
well as from expansion of the company's management contracts at Native American
casinos in California. The stock price of OSI Pharmaceuticals rose sharply
following positive clinical trial data, which showed that the company's lead
drug, Tarceva, was effective in treating lung cancer. Cytyc's stock price
benefited from continued growth in the company's core ThinPrep Pap smear
product. Cytyc's growth prospects were also enhanced by the introduction of a
new diagnostic imaging product and the acquisition of a new women's health
product known as NovaSure. VCA Antech experienced positive growth in its two
core businesses, veterinary labs and animal hospitals, while strategic
acquisitions continued to add to the company's corporate earnings.

WHAT WERE SOME EXAMPLES OF STOCKS THAT DETRACTED FROM RESULTS?

Taro Pharmaceuticals Industries, Wireless Facilities, Odyssey Healthcare, Select
Comfort, and Hot Topic were the largest detractors from the Fund's 12-month
performance. Taro Pharmaceuticals swung from profitability to an unexpected loss
in the second calendar quarter of 2004 as a result of excess inventory and a
sharp decline in sales. Taro Pharmaceuticals Industries also spent heavily to
promote an acquired product that generated revenues which were much weaker than
the company had anticipated. Wireless Facilities experienced disappointing
demand for its outsourcing services for wireless telecommunications service
providers and equipment manufacturers. The company also disclosed accounting
irregularities, which resulted in a restatement of earnings. Odyssey
Healthcare's stock price fell because of an SEC investigation. Odyssey also saw
earnings decline at its hospice operations because of higher-than-expected
pharmaceutical and labor costs and adverse Medicare-reimbursement developments.
Select Comfort was hurt by negative publicity related to mold

Stocks of small companies may be subject to higher price volatility,
significantly lower trading volumes, and greater spreads between bid and ask
prices than stocks of larger companies. Small companies may be more vulnerable
to adverse business or market developments than mid- or large-capitalization
companies.

problems in the company's airbed mattresses. Hot Topic, an alternative teen
retailer, experienced disappointing sales growth mainly because of sluggish
demand for the company's less-traditional style of apparel and accessories. We
sold each of these Fund holdings during the reporting period.

WERE THERE ANY SIGNIFICANT NEW HOLDINGS OR SALES DURING THE PERIOD?

With energy prices at record-high levels, we established Fund positions in Cal
Dive, International Grey Wolf, and Atwood Oceanics. In the materials sector, we
purchased shares of Arch Coal. In the industrials sector, we added Terex, a
manufacturer of equipment for construction and surface mining, and Actuant, a
manufacturer of recreational-vehicle components and other tools and supplies. We
added casino operator Penn National Gaming to the portfolio's consumer
discretionary holdings. In health care, we added managed care company Sierra
Health Services.

In addition to selling the Fund's primary detractors, we eliminated NetScreen
Technologies, AdvancePCS, Mid Atlantic Medical Services, and Documentum from the
Fund's portfolio. Each of these companies was acquired during the reporting
period. We also sold the Fund's holdings in DVD retailer NetFlix and in
semiconductor equipment manufacturers MKS Instruments, Brooks Automation, and
August Technology. Each of these sales reflected our belief that the issuer's
business prospects were deteriorating.

DID THE FUND CHANGE ITS INDUSTRY GROUP WEIGHTINGS DURING THE FISCAL YEAR?

We significantly reduced the Fund's weighting in the information technology
sector from 34.6% to 18.6%

of the portfolio's net assets. This key decision--particularly our reduction in
exposure to semiconductor stocks--had a positive effect on the Fund's 12-month
performance. The Fund also benefited by establishing a position in the materials
sector. We took the Fund's exposure to materials from 0% to 3.6% of net assets.
We also increased the Fund's weighting in health care from 16.5% to 20.0% of net
assets. We increased the Fund's weighting in the strongly performing energy
sector from 2.4% to 7.1% of net assets during the Fund's fiscal year.
Unfortunately, the Fund's underweighted position early in the reporting period
hurt relative performance.

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

At the end of October 2004, the Fund held over-weighted positions relative to
the Russell 2000(R) Growth Index in the consumer discretionary and energy
sectors and underweighted positions in consumer staples, industrials, and
information technology. At the end of the reporting period, the Fund had no
holdings in the telecommunications services or utilities sectors.

WHAT DO YOU ANTICIPATE GOING FORWARD?

With the uncertainty of the presidential election now behind us, investors can
now focus their attention on market fundamentals. Although high energy prices
and terrorism concerns remain risk factors, we believe that the combination of
moderate economic growth and relatively low interest rates may help support
decent stock-price action going forward. We intend to continue to focus on
stocks of companies with strong growth prospects.

NOTES TO FINANCIAL STATEMENTS

NOTE 1 -- ORGANIZATION AND BUSINESS:

The MainStay Funds (the "Trust") was organized on January 9, 1986 as a
Massachusetts business trust. The Trust is registered under the Investment
Company Act of 1940, as amended (the "1940 Act"), as an open-end management
investment company and comprises twenty-two funds (collectively referred to as
the "Funds"). These financial statements and notes relate only to MainStay Small
Cap Growth Fund (the "Fund"), a diversified fund.

The Fund currently offers three classes of shares. Distribution of Class A
shares and Class B shares commenced on June 1, 1998. Class C shares were
initially offered on September 1, 1998. 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 within one year of purchase
of Class C shares. Class A shares, Class B shares and Class C shares bear the
same voting (except for issues that relate solely to one class), dividend,
liquidation and other rights and conditions except that the Class B shares and
Class C shares are subject to higher distribution fee rates. Each class of
shares bears distribution and/or service fee payments under a distribution plan
pursuant to Rule 12b-1 under the 1940 Act.

The Fund's investment objective is to seek long-term capital appreciation by
investing primarily in securities of small-cap companies.

Small-capitalization companies may be more volatile in price and have
significantly lower trading volumes than companies with larger capitalizations.
They may be more vulnerable to adverse business or market developments than
large-capitalization companies.

NOTE 2 -- SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with generally accepted
accounting principles and follows the significant accounting policies described
below.

(A) SECURITIES VALUATION.  Equity securities are valued at the latest quoted
sales prices as of the close of 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. 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.
Securities for which market quotations are not readily available are valued by
methods deemed by the Board of Trustees to represent fair value. Reasons for
which securities may be valued in this manner include, but are not limited to,
trading for a security has been halted or suspended, a security has been
de-listed from a national exchange, or trading on a security's primary market is
temporarily closed at a time when under normal conditions it would be open. The
Fund did not hold securities at October 31, 2004, that were valued in such
manner.

(B) SECURITIES LENDING.  The Fund may lend its securities to broker-dealer 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.

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

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

(D) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are
recorded on the ex-dividend date. The Fund intends to declare and pay any
dividends quarterly and capital gain distributions, if any, annually. 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.

The following table discloses the current period reclassification between
accumulated net investment loss and

 18   MainStay Small Cap Growth Fund


additional paid-in-capital arising from permanent differences; net assets at
October 31, 2004, are not affected.

<Table>
<Caption>
  ACCUMULATED NET     ADDITIONAL
  INVESTMENT LOSS   PAID-IN CAPITAL
                 
    $5,687,301        $(5,687,301)
</Table>

The reclassification for the Fund is due to the fact that net operating losses
cannot be carried forward for federal income tax purposes.

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

(F) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred except where direct allocations of expenses can be made. Expenses
(other than expenses incurred under the distribution plans) are allocated to
separate classes of shares based upon their relative net asset value on the date
the expenses are incurred. The expenses borne by the Fund, including those of
related parties to the Fund, are shown in the Statement of Operations.

(G) USE OF ESTIMATES.  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.

NOTE 3 -- FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER AND SUBADVISOR.  New York Life Investment Management LLC ("NYLIM" or
the "Manager"), an indirect wholly-owned subsidiary of New York Life Insurance
Company ("New York Life"), serves as the Fund's manager. The Manager provides
offices, conducts clerical, recordkeeping and bookkeeping services, and keeps
the financial and accounting records required for the Fund. The Manager also
pays the salaries and expenses of all personnel affiliated with the Fund and all
the operational expenses that are not the responsibility of the Fund. MacKay
Shields LLC (the "Subadvisor"), a registered investment advisor and indirect
wholly-owned subsidiary of New York Life, is responsible for the day-to-day
portfolio management of the Fund.

The Trust, on behalf of the Fund, pays the Manager a monthly fee for services
performed and the facilities furnished at an annual rate of 1.00% of the Fund's
average daily net assets up to $1.0 billion and 0.95% on assets in excess of
$1.0 billion. Effective as of August 1, 2004, NYLIM has voluntarily agreed to
waive its management fee by 0.15% of the Fund's average net assets. In addition,
effective December 1, 2004, NYLIM has voluntarily agreed to reimburse the
expenses of the Fund to the extent that operating expenses would exceed on an
annualized basis 1.70%, 2.45% and 2.45% of the average daily net assets of the
Class A, Class B and Class C shares, respectively. For the year ended October
31, 2004, the Manager earned from the Fund $2,615,279 and waived $91,982 of its
fee.

Pursuant to the terms of a Sub-Advisory Agreement between NYLIM and MacKay
Shields, the Manager paid the Subadvisor a monthly fee at an annual rate of
0.50% of the average daily net assets of the Fund. To the extent that the
Manager has agreed to voluntarily reduce its fee, the Subadvisor has voluntarily
agreed to do so proportionately.

(B) DISTRIBUTION AND SERVICE FEES.  The Trust, on behalf of the Fund, has a
Distribution Agreement with NYLIFE Distributors LLC (the "Distributor"), an
indirect wholly-owned subsidiary of New York Life. The Fund, with respect to
each class of shares, has adopted distribution plans (the "Plans") in accordance
with the provisions of Rule 12b-1 under the 1940 Act. Pursuant to the Class A
Plan, the Distributor receives a monthly fee from the Fund at an annual rate of
0.25% of the average daily net assets of the Fund's Class A shares, which is an
expense of the Class A shares of the Fund for distribution or service activities
as designated by the Distributor. Pursuant to the Class B and Class C Plans, the
Fund pays the Distributor a monthly fee, which is an expense of the Class B and
Class C shares of the Fund, at the annual rate of 0.75% of the average daily net
assets of the Fund's Class B and Class C shares. The Distribution Plans provide
that the Class B and Class C shares of the Fund 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 Fund.

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

(C) SALES CHARGES.  The Fund was advised by the Distributor that the amount of
sales charges retained on sales of Class A shares was $30,966 for the year ended
October 31, 2004. The Fund was also advised that the Distributor retained
contingent deferred sales charges on redemptions of Class A, Class B and Class C
shares of $2,899, $229,242 and $1,011, respectively, for the year ended October
31, 2004.

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

(D) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT.  NYLIM
Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's
transfer, dividend disbursing and shareholder servicing agent. NYLIM Service has
entered into an agreement with Boston Financial Data Services ("BFDS") pursuant
to which BFDS will perform certain of the services for which NYLIM Service is
responsible. Transfer agent expenses for the year ended October 31, 2004
amounted to $1,491,345.

(E) NON-INTERESTED TRUSTEES FEES.  Non-Interested Trustees are paid an annual
retainer fee of $45,000, $2,000 for each Board meeting, $1,000 for each
Committee meeting and $500 for each Valuation Subcommittee telephonic meeting
attended plus reimbursement for travel and out-of-pocket expenses. The Lead
Non-Interested Trustee is also paid an annual retainer fee of $20,000. The Audit
Committee Chairman receives an additional $2,000 for each meeting of the Audit
Committee attended and the Chairpersons of the Brokerage Committee, Operations
Committee and Performance Committee each receive an additional $1,000 for each
meeting of the Brokerage Committee, Operations Committee and Performance
Committee attended, respectively. In addition, each Non-Interested Trustee is
paid $1,000 for attending meetings of the Non-Interested Trustees held in
advance of or in connection with Board/Committee meetings. The Trust allocates
trustees fees in proportion to the net assets of the respective Funds. Thus the
Small Cap Growth Fund only pays a portion of the fees identified above.

(F) OTHER.  Fees for the cost of legal services, included in Professional fees
as shown on the Statement of Operations, provided to the Fund by the Office of
the General Counsel of NYLIM amounted to $7,862 for the year ended October 31,
2004.

The Fund pays the Manager a monthly fee for recordkeeping services provided
under the Accounting Agreement at the annual rate of 1/20 of 1% for the first
$20 million of average monthly net assets, 1/30 of 1% of the next $80 million of
average monthly net assets and 1/100 of 1% of any amount in excess of $100
million of average monthly net assets. Fees for recordkeeping services provided
to the Fund by the Manager amounted to $52,820 for the year ended October 31,
2004.

NOTE 4 -- CUSTODIAN:

The Bank of New York is custodian of cash and securities of the Fund. Custodial
fees are charged the Fund based on the market value of securities in the Fund
and the number of certain cash transactions incurred by the Fund.

NOTE 5 -- FEDERAL INCOME TAX:

As of October 31, 2004, the components of accumulated loss on a tax basis were
as follows:

<Table>
<Caption>
                                           TOTAL
  ACCUMULATED CAPITAL    UNREALIZED     ACCUMULATED
   AND OTHER LOSSES     APPRECIATION       LOSS
                                 

    $(179,173,011)      $50,899,093    $(128,273,918)
</Table>

The difference between book-basis and tax-basis unrealized appreciation is due
to wash sale deferrals.

At October 31, 2004, for federal income tax purposes, capital loss carryforwards
of $179,173,011 were available, as shown in the table below, to the extent
provided by regulations to offset future realized gains of the Fund through the
years indicated. To the extent that these carryforwards are used to offset
future capital gains, it is probable that the capital gains so offset will not
be distributed to shareholders.

October 31, 2004.

NOTE 6 -- PURCHASES AND SALES OF SECURITIES (IN 000'S):

During the year ended October 31, 2004, purchases and sales of securities, other
than short-term securities, were $193,175 and $199,282, respectively.

NOTE 7 -- PORTFOLIO SECURITIES LOANED:

As of October 31, 2004, the Fund had securities on loan with an aggregate market
value of $34,994,792. The Fund received $36,141,121 in cash as collateral for
securities on loan which was used to purchase highly liquid short-term
investments in accordance with the Fund's securities lending procedures.
Pursuant to Rule 2a-7, securities purchased with collateral received are valued
at amortized cost.

NOTE 8 -- LINE OF CREDIT:

The Fund and certain affiliated funds maintain a line of credit of $160,000,000
with a syndicate of banks in order to secure a source of funds for temporary
purposes to meet unanticipated or excessive shareholder redemption requests. The
funds pay a commitment fee, at an annual rate of .075% of the average commitment
amount, regardless of usage, to The Bank of New York, which acts as

 20   MainStay Small Cap Growth Fund


agent to the syndicate. Such commitment fees are allocated among the funds based
upon net assets and other factors. Interest on any revolving credit loan is
charged based upon the Federal Funds Advances rate. There were no borrowings on
the line of credit during the year ended October 31, 2004.

NOTE 10 -- OTHER MATTERS:

NYLIM and mutual funds that NYLIM advises have received requests for information
from various government authorities and regulatory bodies regarding market
timing, late trading, operations, fees, expenses, and other matters. NYLIM and
the funds it advises are cooperating fully in responding to these requests. As
reported in response to those requests for information, NYLIM was previously
party to agreements with certain registered representatives of broker-dealers
relating to the level of trading by clients or customers of those registered
representatives in shares of certain funds of the Trust. NYLIM is continuing to
review what effect, if any, transactions under these agreements may have had on
the funds, and will continue to apprise the Board of Trustees of such
information. NYLIM does not believe at this time that such trading had any
material effect on the funds' financial statements or their shareholders. To
date, substantially all of the costs associated with these and other regulatory
matters have been borne by NYLIM. Except as described below, neither NYLIM nor
the funds advised by it have any reason to believe that they have been targeted
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.
Discussions have been held with the SEC concerning a possible resolution of this
matter. These discussions are continuing, but there can be no assurance at this
time as to the outcome of these efforts.

NOTE 11 -- CHANGE IN INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM (UNAUDITED):

On March 8, 2004, KPMG LLP ("KPMG") was selected as the Trust's independent
auditor for the 2004 fiscal year. The selection of KPMG was recommended by the
Trust's Audit Committee, comprised of all Non-Interested Trustees, and was
approved by the Trust's Board of Trustees.

The predecessor independent auditor's reports on the Trust's financial
statements for the period ended October 31, 2003 and year ended December 31,
2002 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 periods, and through the date of engagement of KPMG, there
were no disagreements between 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 periods.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Trustees and Shareholders of
The MainStay Funds:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of the MainStay Small Cap Growth Fund (the
"Fund"), one of the funds constituting The MainStay Funds, as of October 31,
2004, and the related statement of operations, statement of changes in net
assets and the financial highlights for the year then ended. These financial
statements and financial highlights are the responsibility of the Fund's
management. Our responsibility is to express an opinion on these financial
statements and financial highlights based on our audit. The statement of changes
in net assets for the period ended October 31, 2003 and the year ended December
31, 2002, and the financial highlights for the periods presented through October
31, 2003, were audited by other auditors, whose report dated December 18, 2003
expressed an unqualified opinion thereon.

We conducted our audit in accordance with the Standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
also includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2004 by correspondence with the custodian and
brokers. As to securities purchased or sold but not yet received or delivered,
we performed other appropriate auditing procedures. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
MainStay Small Cap Growth Fund of The MainStay Funds as of October 31, 2004, the
results of its operations, the changes in its net assets and its financial
highlights for the year then ended, in conformity with U.S. generally accepted
accounting principles.

                    Annual Report

                    October 31, 2004


MESSAGE FROM
THE PRESIDENT

During the 12 months ended October 31, 2004, the U.S. stock market advanced, but
its pace and direction were by no means steady. Small- and mid-capitalization
stocks tended to outperform large-cap issues, and value stocks generally
outperformed growth stocks.

Economic activity, as measured by gross domestic product, increased from 4.2% in
the fourth quarter of 2003 to 4.5% in the first quarter of 2004. The pace of
economic growth slowed to 3.3% in the second quar-
ter of 2004, and according to preliminary estimates from the Bureau of Economic
Analysis, gross domestic product grew at a seasonally adjusted annual rate of
3.9% in the third quarter of 2004.

Interest rates began the reporting period at a low 1.00%. In June 2004, the
Federal Open Market Committee responded to expanding output and improved labor
markets by raising the targeted federal funds rate by 25 basis points. Similar
moves in August and September brought the targeted federal funds rate to 1.75%.
In its September 2004 release, the Federal Open Market Committee affirmed its
belief that monetary policy remained accommodative.

Despite rising interest rates, bond markets generally advanced. High-yield bonds
and emerging-market debt were particularly strong. The U.S. dollar declined
relative to most other currencies, which helped U.S. exporters.

In pursuing its investment objective, each MainStay Fund consistently seeks to
apply a well-defined investment process in all market environments. We believe
that a consistent, disciplined investment approach can help investors make more
prudent and practical decisions regarding their investments.

In the report that follows, you'll find additional information about the market
forces, investment decisions, and individual securities that affected your
MainStay Fund during the 12 months ended October 31, 2004. We thank you for
investing with us, and we look forward to many years of continued service in
your behalf.

Performance tables and graphs do not reflect the deduction of taxes that a
shareholder would pay on distributions or Fund-share redemptions. Total returns
reflect change in share price, reinvestment of dividend and capital-gain
distributions, and maximum applicable sales charges explained in this paragraph.
The graphs assume an initial investment of $10,000 and reflect the deduction of
all sales charges that would have applied for the period of investment. Class A
shares are sold with a maximum initial sales charge of 5.5% and an annual 12b-1
fee of .25%. Class B shares are sold with no initial sales charge, are subject
to a contingent deferred sales charge (CDSC) of up to 5% if redeemed within the
first six years of purchase, and have an annual 12b-1 fee of 1.00%. Class C
shares are sold with no initial sales charge, are subject to a CDSC of 1% if
redeemed within one year of purchase, and have an annual 12b-1 fee of 1.00%.
Performance figures reflect certain fee waivers and/or expense limitations,
without which total returns may have been lower. The fee waivers and/or expense
limitations are voluntary and may be discontinued at any time. From inception
(6/1/98) through 8/31/98, performance for Class C shares (first offered 9/1/98)
includes the historical performance of Class B shares adjusted to reflect the
applicable CDSC for Class C shares.

1. The Russell 2000(R) Value Index is an unmanaged index that measures the
   performance of those Russell 2000(R) companies with lower price-to-book
   ratios and lower forecasted growth values. The Russell 2000(R) Index is an
   unmanaged index that measures the performance of the 2,000 smallest companies
   in the Russell 3000(R) Index which, in turn, is an unmanaged index that
   measures the performance of the 3,000 largest U.S. companies based on total
   market capitalization. Results assume the reinvestment of all income and
   capital gains. The Russell 2000(R) Value Index is considered to be the Fund's
   broad-based securities-market index for comparison purposes. An investment
   cannot be made directly into an index.
2. Lipper Inc. is an independent fund performance monitor. Results are based on
   total returns with all dividend and capital-gain distributions reinvested.

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

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 data 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 Caroline Evascu of MacKay Shields LLC

CAN YOU EXPLAIN HOW THE FUND'S PORTFOLIO MANAGEMENT CHANGED DURING THE REPORTING
PERIOD?

At a special meeting held on June 16, 2004, the shareholders of MainStay Small
Cap Value Fund approved a new subadvisory agreement between the Fund's
investment manager, New York Life Investment Management LLC, and MacKay Shields
LLC to appoint MacKay Shields as the new subadvisor to the Fund effective June
30, 2004, replacing Dalton, Greiner, Hartman, Maher & Co. Another change during
the reporting period was that as of July 6, 2004, the Fund was no longer closed
to new investors.

The Fund's principal investment strategy did not change. The Fund continues
normally to invest at least 80% of its assets in companies with market
capitalizations at the time of investment comparable to companies in the Russell
2000(R) Value Index.(1) Under its new management, however, the Fund's investment
process did change.

CAN YOU BRIEFLY DESCRIBE THE FUND'S INVESTMENT APPROACH?

At MacKay Shields, we use an investment-selection process that focuses on stocks
that meet three criteria: inexpensive valuations, free cash flow, and multiple
appreciation drivers, or catalysts. We look for stocks that are inexpensive
relative to the Russell benchmark, their peer group, or historical valuations.
We take a long-term approach to investing and rely primarily on our proprietary
fundamental research. The portfolio is constructed using a bottom-up stock-
selection process. Stocks will be sold either when they meet our price objective
or when we believe there is a negative change in the fundamental performance of
the issuer.

Since this has been the Fund's investment approach since June 30, 2004, the
remainder of our discussion will address the four-month period from June 30
through October 31, 2004.

HOW DID THE RUSSELL 2000(R) VALUE INDEX PERFORM FROM JUNE 30 THROUGH OCTOBER 31,
2004?

The Russell 2000(R) Value Index returned 1.71% for the period from June 30
through October 31, 2004. Only three sectors posted meaningful positive
returns--energy, financials, and materials. Financials remained the largest
sector weighting in the Index.

WHAT FACTORS MOST SIGNIFICANTLY AFFECTED FUND PERFORMANCE DURING THE PERIOD?

The Fund's overweighted position and strong security selection in the energy
sector boosted the Fund's results relative to the benchmark. Our stock selection
in information technology also helped, although the Fund's overweighted exposure
to this under-performing sector detracted. An underweighted position in the
strongly performing financials sector and security selection in the industrials
and consumer discretionary sectors also hurt the Fund's relative performance.

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

Too, Inc., a lifestyle apparel and personal-care products retailer, posted
record third-quarter sales. The record sales--in combination with the
announcement of a share repurchase program to enhance shareholder value--made
Too the best-performing stock in the Fund's portfolio during the reporting
period. Pharmaceutical Product Development provides global
research-and-development services on a contract or consulting basis for the
pharmaceutical and biotechnology industries. The company's shares recorded a
double-digit percentage increase when third-quarter earnings beat Wall Street
expectations. Offshore Logistics provides helicopter transportation services to
the offshore oil and gas industry. The company's shares appreciated on strong
second-quarter results and anticipation of increased exploration and development
activity, which would directly benefit the company's revenue stream.

WHICH STOCKS UNDERPERFORMED?

In industrials, Integrated Electrical Services, Quality Distribution, and Mesa
Airlines provided disappointing performance, despite strong sector fundamentals.
Integrated Electrical Services provides data communication services, which
include the installation of wiring for computer networks and fiber optic
telecommunications systems. Quality Distribution transports a broad range of
chemical products and also provides transportation management, transloading,
tank cleaning, dry-bulk handling, and other logistical services. The company's
weakness was primarily due to missed second-quarter 2004 earnings-per-share
projections. Mesa Airlines underperformed amid general weakness in the airline

Stocks of small companies may be subject to higher price volatility,
significantly lower trading volumes, and greater spreads between bid and ask
prices than stocks of larger companies. Small companies may be more vulnerable
to adverse business or market developments than mid- or large-capitalization
companies.

industry. When U.S. Airways reentered Chapter 11, many investors feared that
others might follow and that Delta Airlines might be among them.

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

When we took over management of the Fund's portfolio, we elected to sell several
securities that did not meet our investment philosophy. The sales took place
during the Fund's transition period from the end of June through the end of
October. As a result of these sales and the Fund's subsequent purchases, the
Fund's turnover rate exceeded 100%.

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

As of October 31, 2004, the Fund held overweighted positions in the information
technology, health care, and consumer discretionary sectors, based on bottom-up
security selection driven by attractive valuations. The Fund held underweighted
positions in financials, utilities, and materials. These sectors have largely
outperformed over the last several years, and most stocks in these areas were
trading at the high end of their historical ranges.

WHAT DO YOU ANTICIPATE GOING FORWARD?

We are optimistic about our efforts to move the Fund toward attractive value
opportunities that, in our opinion, should outperform over the long term. We
will continue to emphasize stocks with better-than-market visibility based on
earnings and cash-flow generation. We remain confident in our disciplined
classic value strategy, which seeks to invest in fundamentally strong companies
selling at unusually attractive valuations.

NOTES TO FINANCIAL STATEMENTS

NOTE 1 -- ORGANIZATION AND BUSINESS:

The MainStay Funds (the "Trust") was organized on January 9, 1986 as a
Massachusetts business trust. The Trust is registered under the Investment
Company Act of 1940, as amended (the "1940 Act"), as an open-end management
investment company and comprises twenty-two funds (collectively referred to as
the "Funds"). These financial statements and notes relate only to MainStay Small
Cap Value Fund (the "Fund"), a diversified fund. The Board of Trustees of the
Trust had approved the closure of the Fund to new investors, effective December
1, 2001. The Fund was re-opened to investors on July 6, 2004, after the
appointment of the new Subadvisor, MacKay Shields LLC.

The Fund currently offers three classes of shares. Beginning January 31, 2005,
the Fund will also offer Class I shares. Distribution of Class A shares and
Class B shares commenced on June 1, 1998. Class C shares were initially offered
on September 1, 1998. 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 within one year of purchase of Class C
shares. Class A shares, Class B shares and Class C shares bear the same voting
(except for issues that relate solely to one class), dividend, liquidation and
other rights and conditions except that the Class B shares and Class C shares
are subject to higher distribution fee rates. Each class of shares bears
distribution and/or service fee payments under a distribution plan pursuant to
Rule 12b-1 under the 1940 Act.

The Fund's investment objective is to seek long-term capital appreciation by
investing primarily in securities of small-cap companies.

Small-capitalization companies may be more volatile in price and have
significantly lower trading volumes than companies with larger capitalizations.
They may be more vulnerable to adverse business or market developments than
large-capitalization companies.

NOTE 2 -- SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with generally accepted
accounting principles and follows the significant accounting policies described
below.

(A) SECURITIES VALUATION.  Equity securities are valued at the latest quoted
sales prices as of the close of 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. 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.
Securities for which market quotations are not readily available are valued by
methods deemed by the Board of Trustees to represent fair value. Reasons for
which securities may be valued in this manner include, but are not limited to,
trading for a security has been halted or suspended, a security has been
de-listed from a national exchange, or trading on a security's primary market is
temporarily closed at a time when under normal conditions it would be open. The
Fund did not hold securities at October 31, 2004, that were valued in such
manner.

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

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

(C) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are
recorded on the ex-dividend date. The Fund intends to declare and pay any
dividends quarterly and capital gain distributions, if any, annually. 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.

The following table discloses the current period reclassification between
accumulated net investment loss, accumulated undistributed net realized gain on
investments and additional paid-in capital arising from permanent differences;
net assets at October 31, 2004, are not affected.

</Table>

 16   MainStay Small Cap Value Fund


The reclassification for the Fund is primarily attributable to net operating
losses that offset undistributed net short-term securities gains for federal
income tax purposes, real estate investment trusts and distributions paid in
connection with the redemption of Fund shares.

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

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

(E) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred except where direct allocations of expenses can be made. Expenses
(other than expenses incurred under the distribution plans) are allocated to
separate classes of shares based upon their relative net asset value on the date
the expenses are incurred. The expenses borne by the Fund, including those of
related parties to the Fund, are shown in the Statement of Operations.

(F) USE OF ESTIMATES.  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.

NOTE 3 -- FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER AND SUBADVISOR.  New York Life Investment Management LLC ("NYLIM" or
the "Manager"), an indirect wholly-owned subsidiary of New York Life Insurance
Company ("New York Life"), serves as the Fund's manager. The Manager provides
offices, conducts clerical, recordkeeping and bookkeeping services, and keeps
the financial and accounting records required for the Fund. The Manager also
pays the salaries and expenses of all personnel affiliated with the Fund and all
the operational expenses that are not the responsibility of the Fund. Dalton,
Greiner, Hartman, Maher & Co. was responsible for the day-to-day portfolio
management of the Fund through June 29, 2004. Effective June 30, 2004, pursuant
to shareholder approval, NYLIM appointed MacKay Shields LLC ("MacKay") as the
new Subadvisor (the "Subadvisor") to the Fund at a meeting held on June 16,
2004. (See page 21.)

Prior to July 1, 2004, the Trust, on behalf of the Fund, paid the Manager a
monthly fee for services performed and the facilities furnished at an annual
rate of 1.00% of the Fund's average daily net assets on assets up to $1.0
billion and 0.95% on assets over $1.0 billion. Effective July 1, 2004, the Trust
pays the Manager an annual rate of 0.85% of the Fund's average daily net assets
on assets up to $1.0 billion and 0.80% on assets over $1.0 billion. Also
effective July 1, 2004, for a two-year period, NYLIM has voluntarily agreed to
waive that portion of its fee in excess of 0.60% of the Fund's average daily net
assets. The Manager has also voluntarily agreed to reimburse the expenses of the
Fund to the extent that operating expenses would exceed on an annualized basis
1.90%, 2.65% and 2.65% of the average daily net assets of the Class A, Class B
and Class C shares, respectively. For the year ended October 31, 2004, the
Manager earned from the Fund $1,200,499 and waived $108,819 of its fee.

Pursuant to the terms of a Sub-Advisory Agreement between NYLIM and the
Subadvisor, the Manager paid the Subadvisor a monthly fee of one-half of the
management fee, net of management fee waivers, expense limitations and
reimbursements. To the extent that the Manager has agreed to reimburse Fund
expenses, MacKay has voluntarily agreed to do so proportionately.

(B) DISTRIBUTION AND SERVICE FEES.  The Trust, on behalf of the Fund, has a
Distribution Agreement with NYLIFE Distributors LLC ("the Distributor"), an
indirect wholly-owned subsidiary of New York Life. The Fund, with respect to
each class of shares, has adopted distribution plans (the "Plans") in accordance
with the provisions of Rule 12b-1 under the 1940 Act. Pursuant to the Class A
Plan, the Distributor receives a monthly fee from the Fund at an annual rate of
0.25% of the average daily net assets of the Fund's Class A shares, which is an
expense of the Class A shares of the Fund for distribution or service activities
as designated by the Distributor. Pursuant to the Class B and Class C Plans, the
Fund pays the Distributor a monthly fee, which is an expense of the Class B and
Class C shares of the Fund, at the annual rate of 0.75% of the average daily net
assets of the Fund's Class B and Class C shares. The Distribution Plans provide
that the Class B and Class C shares of the Fund 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 Fund.

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

(C) SALES CHARGES.  The Fund was advised by the Distributor that the amount of
sales charges retained on sales of Class A shares was $12,923 for the year ended
October 31, 2004. The Fund was also advised that the Distributor retained
contingent deferred sales charges on

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

redemptions of Class A, Class B and Class C shares of $874, $58,769 and $199,
respectively, for the year ended October 31, 2004.

(D) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT.  NYLIM
Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's
transfer, dividend disbursing and shareholder servicing agent. NYLIM Service has
entered into an agreement with Boston Financial Data Services ("BFDS") pursuant
to which BFDS will perform certain of the services for which NYLIM Service is
responsible. Transfer agent expenses for the year ended October 31, 2004,
amounted to $501,279.

(E) NON-INTERESTED TRUSTEES FEES.  Non-Interested Trustees are paid an annual
retainer fee of $45,000, $2,000 for each Board meeting, $1,000 for each
Committee meeting and $500 for each Valuation Subcommittee telephonic meeting
attended plus reimbursement for travel and out-of-pocket expenses. The Lead
Non-Interested Trustee is also paid an annual retainer fee of $20,000. The Audit
Committee Chairman receives an additional $2,000 for each meeting of the Audit
Committee attended and the Chairpersons of the Brokerage Committee, Operations
Committee and Performance Committee each receive an additional $1,000 for each
meeting of the Brokerage Committee, Operations Committee and Performance
Committee attended, respectively. In addition, each Non-Interested Trustee is
paid $1,000 for attending meetings of the Non-Interested Trustees held in
advance of or in connection with Board/Committee meetings. The Trust allocates
trustees fees in proportion to the net assets of the respective Funds. Thus the
Small Cap Value Fund only pays a portion of the fees identified above.

(F) OTHER.  Fees for the cost of legal services, included in Professional fees
as shown on the Statement of Operations, provided to the Fund by the Office of
the General Counsel of NYLIM amounted to $3,882 for the year ended October 31,
2004.

The Fund pays the Manager a monthly fee for recordkeeping services provided
under the Accounting Agreement at the annual rate of 1/20 of 1% for the first
$20 million of average monthly net assets, 1/30 of 1% of the next $80 million of
average monthly net assets and 1/100 of 1% of any amount in excess of $100
million of average monthly net assets. Fees for recordkeeping services provided
to the Fund by the Manager amounted to $39,329 for the year ended October 31,
2004.

NOTE 4 -- CUSTODIAN:

The Bank of New York is custodian of cash and securities of the Fund. Custodial
fees are charged the Fund based on the market value of securities in the Fund
and the number of certain cash transactions incurred by the Fund.

NOTE 5 -- FEDERAL INCOME TAX:

syndicate. Such commitment fees are allocated among the funds based upon net
assets and other factors. Interest on any revolving credit loan is charged based
upon the Federal Funds Advances rate. There were no borrowings on the line of
credit during the year ended October 31, 2004.

NOTE 9 -- OTHER MATTERS:

NYLIM and mutual funds that NYLIM advises have received requests for information
from various government authorities and regulatory bodies regarding market
timing, late trading, operations, fees, expenses, and other matters. NYLIM and
the funds it advises are cooperating fully in responding to these requests. As
reported in response to those requests for information, NYLIM was previously
party to agreements with certain registered representatives of broker-dealers
relating to the level of trading by clients or customers of those registered
representatives in shares of certain funds of the Trust. NYLIM is continuing to
review what effect, if any, transactions under these agreements may have had on
the funds, and will continue to apprise the Board of Trustees of such
information. NYLIM does not believe at this time that such trading had any
material effect on the funds' financial statements or their shareholders. To
date, substantially all of the costs associated with these and other regulatory
matters have been borne by NYLIM. Except as described below, neither NYLIM nor
the funds advised by it have any reason to believe that they have been targeted
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.
Discussions have been held with the SEC concerning a possible resolution of this
matter. These discussions are continuing, but there can be no assurance at this
time as to the outcome of these efforts.

NOTE 10 -- CHANGE IN INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM (UNAUDITED):

On March 8, 2004, KPMG LLP ("KPMG") was selected as the Trust's independent
auditor for the 2004 fiscal year. The selection of KPMG was recommended by the
Trust's Audit Committee, comprised of all Non-Interested Trustees, and was
approved by the Trust's Board of Trustees.

The predecessor independent auditor's reports on the Trust's financial
statements for the period ended October 31, 2003 and year ended December 31,
2002 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 periods, and through the date of engagement of KPMG, there
were no disagreements between 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 periods.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Trustees and Shareholders of
The MainStay Funds:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of the MainStay Small Cap Value Fund (the "Fund"),
one of the funds constituting The MainStay Funds, as of October 31, 2004, and
the related statement of operations, statement of changes in net assets and the
financial highlights for the year then ended. These financial statements and
financial highlights are the responsibility of the Fund's management. Our
responsibility is to express an opinion on these financial statements and
financial highlights based on our audit. The statement of changes in net assets
for the period ended October 31, 2003 and the year ended December 31, 2002, and
the financial highlights for the periods presented through October 31, 2003,
were audited by other auditors, whose report dated December 18, 2003 expressed
an unqualified opinion thereon.

We conducted our audit in accordance with the Standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
also includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2004 by correspondence with the custodian and
brokers. As to securities purchased or sold but not yet received or delivered,
we performed other appropriate auditing procedures. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
MainStay Small Cap Value Fund of The MainStay Funds as of October 31, 2004, the
results of its operations, the changes in its net assets and its financial
highlights for the year then ended, in conformity with U.S. generally accepted
accounting principles.

SPECIAL MEETING OF SHAREHOLDERS (UNAUDITED)

At a special meeting held on June 16, 2004, the shareholders of MainStay Small
Cap Value Fund (the "Fund") approved a New Subadvisory Agreement between the
Fund's investment manager, New York Life Investment Management LLC ("NYLIM") and
MacKay Shields LLC ("MacKay Shields") to appoint MacKay Shields as the new
subadvisor to the Fund (the "New Subadvisory Agreement") effective on or about
June 25, 2004. Dalton, Greiner, Hartman, Maher & Co. ("Dalton Greiner") had been
providing advisory services to the Fund since May 31, 1998, most recently
pursuant to an Interim Sub-Advisory Agreement between NYLIM and Dalton Greiner
(the "Interim Agreement") dated February 6, 2004, as previously approved by the
Board. The terms of the New Subadvisory Agreement are substantially similar to
those of the Interim Agreement except for the fees payable to MacKay Shields.

In connection with the approval of the New Subadvisory Agreement, NYLIM has
agreed to the following terms: (1) contractually reduce the Fund's overall
management fee from 1.00% to 0.85% of the Fund's average daily net assets, (2)
voluntarily waive that portion of the Fund's management fee in excess of 0.60%
of the Fund's average daily net assets for a period of two years following the
effective date of the New Subadvisory Agreement and (3) voluntarily reimburse
the Fund from its management fee to the extent the Fund's total operating
expenses exceed 1.90% of average daily net assets for Class A shares and 2.65%
of average daily net assets for Class B and Class C shares. This expense
reimbursement may be discontinued at any time without notice.

Under the New Subadvisory Agreement, MacKay Shields will receive one-half of the
management fee payable to NYLIM with respect to the Fund, net of management fee
waivers, expense limitations and reimbursements.

MESSAGE FROM
THE PRESIDENT

During the 12 months ended October 31, 2004, the U.S. stock market advanced, but
its pace and direction were by no means steady. Small- and mid-capitalization
stocks tended to outperform large-cap issues, and value stocks generally
outperformed growth stocks.

Economic activity, as measured by gross domestic product, increased from 4.2% in
the fourth quarter of 2003 to 4.5% in the first quarter of 2004. The pace of
economic growth slowed to 3.3% in the second quarter of 2004, and according to
preliminary estimates from the Bureau of Economic Analysis, gross domestic
product grew at a seasonally adjusted annual rate of 3.9% in the third quarter
of 2004.

Interest rates began the reporting period at a low 1.00%. In June 2004, the
Federal Open Market Committee responded to expanding output and improved labor
markets by raising the targeted federal funds rate by 25 basis points. Similar
moves in August and September brought the targeted federal funds rate to 1.75%.
In its September 2004 release, the Federal Open Market Committee affirmed its
belief that monetary policy remained accommodative.

Despite rising interest rates, bond markets generally advanced. High-yield bonds
and emerging-market debt were particularly strong. The U.S. dollar declined
relative to most other currencies, which helped U.S. exporters.

In pursuing its investment objective, each MainStay Fund consistently seeks to
apply a well-defined investment process in all market environments. We believe
that a consistent, disciplined investment approach can help investors make more
prudent and practical decisions regarding their investments.

In the report that follows, you'll find additional information about the market
forces, investment decisions, and individual securities that affected your
MainStay Fund during the 12 months ended October 31, 2004. We thank you for
investing with us, and we look forward to many years of continued service in
your behalf.

Sincerely,

/s/ GARY E. WENDLANDT

Gary E. Wendlandt
President

Performance tables and graphs do not reflect the deduction of taxes that a
shareholder would pay on distributions or Fund-share redemptions. Total returns
reflect change in share price, reinvestment of dividend and capital-gain
distributions, and maximum applicable sales charges explained in this paragraph.
The graphs assume an initial investment of $10,000 and reflect the deduction of
all sales charges that would have applied for the period of investment. Class A
shares are sold with a maximum initial sales charge of 5.5% and an annual 12b-1
fee of .25%. Class B shares are sold with no initial sales charge, are subject
to a contingent deferred sales charge (CDSC) of up to 5% if redeemed within the
first six years of purchase, and have an annual 12b-1 fee of 1.00%. Class C
shares are sold with no initial sales charge are subject to a CDSC of 1% if
redeemed within one year of purchase, and have an annual 12b-1 fee of 1.00%.
Class I shares are sold with no initial sales charge or CDSC, have no annual
12b-1 fee, and are generally available to corporate and institutional investors
with a minimum initial investment of $5 million. Class R1 shares are sold with
no initial sales charge or CDSC, and have no annual 12b-1 fee.
Class R2 shares are sold with no initial sales charge or CDSC, and have an
annual 12b-1 fee of .25%. Class R1 and R2 shares are available only through
corporate-sponsored retirement programs, which include certain minimum program
requirements. 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. On
6/9/99, MAP-Equity Fund was reorganized as MainStay MAP Fund Class I shares.
From inception (1/21/71) through 6/8/99, performance for MainStay MAP Fund Class
I shares (first offered 6/9/99) includes the performance of MAP-Equity Fund.
Prior to the reorganization, shares of MAP-Equity Fund were subject to a maximum
4.75% sales charge. From inception (6/9/99) through 12/31/03, performance for
Class R1 and R2 shares (first offered 1/2/04) includes the historical
performance of Class A shares adjusted to reflect the applicable fees and
expenses for Class R1 and R2 shares.

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

Questions answered by portfolio managers Roger Lob, Christopher Mullarkey, and
Michael J. Mullarkey of Markston International, LLC, and by portfolio managers
Mark G. DeFranco and Brian M. Gillott of Jennison Associates LLC

CAN YOU DESCRIBE THE FUND'S INVESTMENT APPROACH?

The Fund normally invests at least 65% of its total assets in equity-type
securities, including common stocks, as well as securities convertible into, or
exchangeable for, common stocks. The Fund employs two subadvisors, Markston
International and Jennison Associates, with complementary investment processes
and styles. In pursuing the Fund's investment objective, each subadvisor seeks
to identify securities that are out of favor but have a catalyst that the
subadvisor believes will lead to improved performance.

WHAT MAJOR FACTORS INFLUENCED THE STOCK MARKET DURING THE 12-MONTH REPORTING
PERIOD ENDED OCTOBER 31, 2004?

Markston International:
The most significant factors that influenced the equity markets were the
continuing war in Iraq, the sharp rise in energy costs, the anticipated outcome
of the Presidential election, and rising interest rates. In addition, investors
were concerned about the growing budget deficit, the rising trade deficit, and
the continued decline of the U.S. dollar.

Jennison Associates:
During the reporting period, mixed economic data left the equity markets
unsettled. Earlier in the Fund's fiscal year, we saw solid growth and a dramatic
rebound in corporate earnings that led to strong equity returns. While high
energy costs and reduced mortgage refinancing kept consumer spending at moderate
levels, corporate spending was quite robust, led by outlays for information
technology. More recently, corporate earnings growth has slowed and the stock
market has been relatively flat. As the period progressed, investors' concerns
included increased geopolitical uncertainty, the impact of high energy prices on
corporate profits, the pace of economic activity, and inflation.

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

Markston International:
Effective stock selection helped the portion of the Fund that we manage to
nearly double the performance of the S&P 500(R) Index.(1) In the beginning of
the reporting period, significant exposure to strong performers among oil, gas,
coal, and utility stocks enhanced results. The Fund was correctly positioned for
an increase in energy prices, which provided us an opportunity to selectively
pare back the Fund's exposure to this area of the market. After capturing
profits on a select group of energy stocks, we spent a significant amount of
time during the second quarter of 2004 finding new and interesting investment
candidates. We believe this helped our portion of the Fund produce positive
results throughout the reporting period, even while other indices were providing
negative returns. When the equity markets rebounded in late July and early
August of 2004, our portion of the Fund's portfolio was well positioned to
benefit from the broad-based rally. We also feel that our decision to
selectively take profits in energy investments and to broaden and diversify
holdings in the financials sector helped position our portion of the Fund
against an inevitable moderation in energy prices.

Jennison Associates:
Our portion of the Fund's portfolio outperformed the S&P 500(R) Index during the
reporting period. On a relative basis, our holdings in materials, energy,
information technology, and health care made the most significant positive
contributions to results. Relative performance was weaker among our holdings in
the consumer discretionary sector, particularly in the media industry, and in
the financials, telecommunication services, and industrials sectors. The last
months of 2003 were difficult for many bottom-up stock pickers, as the rally
tended to be fairly concentrated. We were, however, able to find quite a few
strong performers for the portfolio. In the second and third quarters of 2004,
the Federal Open Market Committee raised the targeted federal funds rate three
times. We believe our portion of the portfolio was well positioned for this
market environment, as materials and energy together constituted

Mid-capitalization companies are generally less established and their stocks may
be more volatile and less liquid than the securities of larger companies. Stocks
of small companies may be subject to higher price volatility, significantly
lower trading volumes, and greater spreads between bid and ask prices than
stocks of larger companies. Small companies may be more vulnerable to adverse
business or market developments than mid- or large-capitalization companies.
Funds that invest in bonds are subject to credit, inflation, and interest-rate
risk and can lose principal value when interest rates rise.

more than 25% of our portion of the Fund's portfolio. We feel that the earnings
growth of our holdings has been significantly enhanced by higher pricing power.

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

Markston International:
Harris Corporation, a manufacturer of communication software and equipment,
enhanced results, as the company benefited from increasing sales to the U.S.
government. The company's new chief executive officer has been cutting costs,
which has helped earnings grow. Monsanto, the world's leading supplier of
genetically modified seeds, saw its stock appreciate when the company managed to
collect royalties from its Brazilian customers. Exposure to Yahoo!, a global
Internet portal, also helped returns in our portion of the Fund's portfolio. The
company experienced solid revenue growth during the reporting period.

Jennison Associates:
Software holding McAfee was a strong performer, as the company completed the
sale of its Sniffer enterprise division. The company also benefited from
better-than-expected growth in both the volume and pricing of its consumer
products. We have pared back on this position to capture some profits as
McAfee's stock price has appreciated. In basic materials, Arch Coal and CONSOL
Energy performed well, because of favorable supply/demand trends for coal and
relatively high natural-gas prices. Our position in Schlumberger also enhanced
results. The company provides advanced techniques for drilling in remote
locations and in difficult geologies. Schlumberger reported better-than-expected
earnings in 2004, as the search for new resources intensified.

WHAT STOCKS UNDERPERFORMED DURING THE REPORTING PERIOD?

Markston International:
Our position in Vitesse Semiconductor, a manufacturer of communications and
storage semiconductors, detracted from results. The stock underperformed when
the recovery in the company's main markets was less robust than expected. Our
exposure to Chiron, a diversified biotechnology and vaccine supplier, hurt
results when the firm's U.K.-based flu vaccine plant, which was expected to
supply the U.S. for the 2004/2005 winter season, was found not to be sterile. We
expect Chiron to return to the U.S. market in the 2005/2006 period. Although we
sold slightly more than a third of our position in Sanmina-SCI at a gain for the
reporting period, the remainder of the position detracted from results when the
stock was hurt by competitive conditions in the electronic manufacturing
services subindustry.

Jennison Associates:
Media stocks in our portion of the Fund's portfolio hurt performance, owing to
concerns about the pace of the advertising recovery. While we thought that
strong advertising sales growth reported in the first quarter of 2004 would
continue throughout the year, this did not occur. As a result, the Fund's
holdings in Westwood One and Interpublic Group detracted from results. Insurance
stocks St. Paul Travelers and American International Group also hurt
performance. St. Paul Travelers, which was created when St. Paul acquired
Travelers Property & Casualty, fell as investors' opinion of management
weakened. Problems were compounded when New York Attorney General Eliot Spitzer
announced an investigation into the insurance industry's practices. In our
opinion, however, the Spitzer investigations may have little direct impact on
St. Paul Travelers. American International Group fell with the overall decline
in the insurance industry. When it became evident that rising interest rates had
hurt the company's third-quarter-2004 results, we eliminated the position.

WERE THERE ANY SIGNIFICANT PURCHASES DURING THE REPORTING PERIOD?

Markston International:
We added American Express, a global provider of financial and travel services,
to our portion of the Fund's portfolio. We believe the company can materially
benefit from Visa's antitrust problems. Boston Scientific, a leading medical
device maker, is another stock we added to the Fund. Many of the company's
products hold number-one or number-two positions in their markets. For the last
two years, we have been watching the market for drug-eluting stents develop. We
purchased Boston Scientific after its stock declined because of manufacturing
issues and related safety concerns. Once we determined that the problems might
have only a short-term impact, we made the stock a significant new holding in
our portion of the Fund's portfolio. Another purchase made during the reporting
period was Citigroup, a global financial institution. With a lower
price-to-earnings ratio and a higher dividend yield than the S&P 500(R) Index,
we believe Citigroup's stock represents good value.

 8   MainStay MAP Fund


Jennison Associates:
We continue to build the portfolio one stock at a time, using a bottom-up,
research-intensive process. During the reporting period, we significantly added
to the Fund's position in Harmony Gold Mining and initiated positions in
Aluminum Corp. of China (Chalco), Alcoa, and Cooper Cameron. Harmony Gold Mining
rallied as the price of gold rose. We initiated a position in Chalco as the fear
of a "hard landing" correction in the Chinese economy resulted in a decline of
over 40% in the company's share price. We believe a rally in the alumina (a raw
material of aluminum) market, coupled with the current positive supply/demand
fundamentals for alumina, should benefit both Chalco and Alcoa. We initiated a
position in Cooper Cameron in April 2004 and have added to the position a number
of times. We believe that Cooper Cameron--a leading manufacturer of oil and gas
pressure control equipment, including equipment used in offshore and subsea
applications--should benefit from future contract awards by major oil companies.

WHAT STOCKS DID YOUR PORTION OF THE FUND'S PORTFOLIO SELL DURING THE REPORTING
PERIOD?

Markston International:
We sold our position in Hartford Financial Services Group, a provider of
financial and insurance products, in light of uncertainties surrounding the
investigation into insurance-industry pricing practices. The Fund's holdings in
Anadarko Petroleum and Unocal were reduced as the stocks of these oil and gas
exploration and production companies appreciated significantly. We eliminated
the Fund's position in Aetna, a major heath care provider, after the stock
reached our price target.

Jennison Associates:
On the basis of our stringent risk/reward criteria, we eliminated the Fund's
positions in Fisher Scientific International, PeopleSoft, Weatherford
International, and Amerada Hess. In each of these cases, the sales had a
positive effect on the Fund's performance. Fisher Scientific International, a
dominant player in the distribution of products to the scientific research and
clinical testing markets, reported several strong quarters of financial results.
We expect continued growth in the company's base business as pharmaceutical
spending increases. Nevertheless, we eliminated the position and captured
profits when the stock met our price target. PeopleSoft stock performed well
when Oracle received approval to acquire the company. We eliminated the Fund's
position when we felt that the stock had reached its fair market value.

DID THE FUND CHANGE ITS INDUSTRY GROUP WEIGHTINGS?

Markston International:
During the 12 months ended October 31, 2004, we significantly increased the
Fund's exposure to stocks in the financials and utilities sectors. In our
portion of the Fund's portfolio, we also modestly increased exposure to the
consumer discretionary sector. During the reporting period, we reduced our
allocations to the health care and information technology sectors.

Jennison Associates:
Any changes in the Fund's weightings are a consequence of our bottom-up
stock-selection process and do not reflect a "sector bet" on the part of our
management team. During the reporting period, the risk/reward discipline that
guides our portion of the Fund's portfolio led us to take profits in many strong
performers. Based on our bottom-up stock selection, we increased the Fund's
weighting in financials and basic materials, particularly in metals & mining and
in select chemical companies, and trimmed the Fund's weighting in consumer
discretionary and energy stocks. As oil prices rallied throughout the year, we
significantly reduced the Fund's exposure to the energy sector. More
specifically, we captured profits from certain energy holdings and reinvested
them in other energy stocks that we felt offered more attractive reward/risk
profiles.

WHAT DO YOU ANTICIPATE GOING FORWARD?

Markston International:
We continue to adhere to a strict bottom-up stock-selection approach, focusing
on securities that we believe offer reward potential that outweighs inherent
risk. In general, we are always looking for stocks that appear inexpensive. In
this context, we look for a catalyst that could cause a stock to appreciate.
While we do not rule out the possibility of unexpected volatility in interest
rates, the dollar, or energy prices over the next six to 12 months, we will
continue to search for securities that we feel can outperform the overall
market.

Jennison Associates:
Many of our new ideas are driven by company-specific catalysts that we believe
have been generally overlooked by the market. We are also closely monitoring
whether or not the Chinese government will continue to be successful in
engineering a "soft landing" for the country's economy, since this may affect
global demand for many commodities. A shift in demand would affect the
fundamentals of several commodity companies held by the Fund. We have

                                                     www.mainstayfunds.com     9


been focused on the basic materials sector for some time now, which has had a
positive impact on performance. We continue to find good supply/ demand
fundamentals among many companies in this diverse sector, but we are mindful of
the inherent cyclicality of these businesses and are selectively taking profits.
We continue to believe this will be a stock-picker's market. We intend to remain
disciplined in our style and philosophy as we seek to uncover new opportunities.

NOTES TO FINANCIAL STATEMENTS

NOTE 1 -- ORGANIZATION AND BUSINESS:

The MainStay Funds (the "Trust") was organized on January 9, 1986 as a
Massachusetts business trust. The Trust is registered under the Investment
Company Act of 1940, as amended (the "1940 Act"), as an open-end management
investment company and comprises twenty-two funds (collectively referred to as
the "Funds"). These financial statements and notes relate only to MainStay MAP
Fund (formerly MainStay MAP Equity Fund, the "Fund"), a diversified fund.

MainStay MAP Fund commenced operations in 1971 as the Mutual Benefit Fund. It
was renamed MAP-Equity Fund on May 1, 1995. Pursuant to an Agreement and Plan of
Reorganization approved by MAP-Equity shareholders on June 3, 1999, the
MAP-Equity Fund was reorganized as the MainStay MAP Equity Fund. As of June 10,
2002 the MainStay MAP Equity Fund was renamed the MainStay MAP Fund. The
financial statements of the MainStay MAP Fund reflect the historical financial
results of the MAP-Equity Fund prior to the reorganization.

The Fund currently offers six classes of shares, Class A shares, Class B shares,
Class C shares, Class I shares, Class R1 shares and Class R2 shares.
Distribution of Class A shares, Class B shares, Class C shares and Class I
shares commenced on June 9, 1999. Distribution of Class R1 shares and Class R2
shares commenced on January 2, 2004. 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 within one year of purchase
of Class C shares. Class I shares, Class R1 shares and Class R2 shares are not
subject to sales charge. The six classes of shares bear the same voting (except
for issues that relate solely to one class), dividend, liquidation and other
rights and conditions except that Class B shares and Class C shares are subject
to higher distribution fee rates than Class A shares and Class R2 shares under a
distribution plan pursuant to Rule 12b-1 under the 1940 Act. Class I shares and
Class R1 shares are not subject to a distribution or service fee. Class R1 and
Class R2 shares are authorized to pay to New York Life Investment Management
LLC, it affiliates, or independent third-party service providers, as
compensation for services rendered to shareholders of Class R1 or Class R2
shares, a shareholder service fee.

The Fund's investment objective is to seek long-term appreciation of capital.
The Fund also seeks to earn income, but this is a secondary objective.

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

NOTE 2 -- SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with generally accepted
accounting principles and follows the significant accounting policies described
below.

(A) SECURITIES VALUATION.  Equity securities are valued at the latest quoted
sales prices as of the close of 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
selected by the Fund's Manager, whose prices reflect broker/dealer supplied
valuations and electronic data processing techniques, if those prices are deemed
by the Fund's Manager to be representative of market values at the regular close
of business of the Exchange. 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. Securities for which market quotations are not
readily available are valued by methods deemed by the Board of Trustees to
represent fair value. Reasons for which securities may be valued in this manner
include, but are not limited to, trading for a security has been halted or
suspended, a security has been de-listed from a national exchange, or trading on
a security's primary market is temporarily closed at a time when under normal
conditions it would be open. The Fund did not hold securities at October 31,
2004, that were valued in such manner.

Certain events may occur between the time that foreign markets close, on which
securities held by the Fund principally trade, and the time at which the Fund's
NAV is calculated. Should the Manager or Subadvisor conclude that such events
may have effected the accuracy of the last price reported on the local foreign
market, the Manager or Subadvisor may, pursuant to procedures adopted by the
Fund, 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.  The Fund's policy is to comply with the requirements
of the Internal Revenue

 22   MainStay MAP Fund


Code applicable to regulated investment companies and to distribute all of its
taxable income to the shareholders of the Fund within the allowable time limits.
Therefore, no federal income or excise tax provision is required.

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

(C) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are
recorded on the ex-dividend date. The Fund intends to declare and pay any
dividends quarterly and capital gain distributions, if any, annually. 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.

The following table discloses the current period reclassification between
accumulated net investment loss, accumulated net realized gain on investments
and additional paid-in capital arising from permanent differences; net assets at
October 31, 2004, are not affected.

<Table>
<Caption>
  ACCUMULATED   ACCUMULATED
      NET       NET REALIZED    ADDITIONAL
  INVESTMENT      GAIN ON        PAID-IN
     LOSS       INVESTMENTS      CAPITAL
                         
  $2,524,420      $111,806     $(2,636,226)
</Table>

The reclassification for the Fund is primarily due to the fact that net
operating losses cannot be carried forward for federal income tax purposes,
foreign currency gain (loss), real estate investment trusts investments and
distributions paid in connection with the redemption of Fund shares.

(D) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  The Fund records security
transactions on the trade date. Realized gains and losses on security
transactions are determined using the identified cost method. Dividend income is
recognized on the ex-dividend date and interest income is accrued as earned.
Discounts and premiums on securities, other than short-term securities,
purchased for the Fund 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 call date. Discounts and
premiums on short-term securities are accreted and amortized, respectively, on
the straight line method. Income from payment-in-kind securities is recorded
daily based on the effective interest method of accrual.

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

(E) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred except where direct allocations of expenses can be made. Expenses
(other than expenses incurred under the distribution plans) are allocated to
separate classes of shares based upon their relative net asset value on the date
the expenses are incurred. The expenses borne by the Fund, including those of
related parties to the Fund, are shown in the Statement of Operations.

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

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

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

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

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

(G) 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.

NOTE 3 -- FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER AND SUBADVISOR.  New York Life Investment Management LLC ("NYLIM" or
the "Manager"), an indirect wholly-owned subsidiary of New York Life Insurance
Company ("New York Life"), serves as the Fund's manager. The Manager provides
offices, conducts

                                                    www.mainstayfunds.com     23

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

clerical, recordkeeping and bookkeeping services, and keeps the financial and
accounting records required for the Fund. The Manager also pays the salaries and
expenses of all personnel affiliated with the Fund and all the operational
expenses that are not the responsibility of the Fund. Markston International LLC
and Jennison Associates LLC (the "Subadvisors") will manage its allocated
portion of the Fund's assets subject to the oversight of NYLIM. Each Subadvisor
is responsible for the day-to-day portfolio management of the Fund.

The Trust, on behalf of the Fund, paid the Manager a monthly fee for services
performed and the facilities furnished at an annual rate of 0.75% of the Fund's
average daily net assets up to $1.0 billion and 0.70% on assets over $1.0
billion. The Manager has voluntarily agreed to reimburse the expenses of the
Fund to the extent that operating expenses would exceed on an annualized basis
1.35%, 2.10% and 2.10% of the average daily net assets of the Class A, Class B
and Class C shares, respectively and an equivalent amount for Class I, Class R1
and Class R2 shares. For the year ended October 31, 2004 earned from the Fund
$6,468,735 and reimbursed the Fund $258,449.

Pursuant to the terms of Sub-Advisory Agreements between the Manager and the
Subadvisors, the Manager pays the Subadvisors a monthly fee at an annual rate of
the Fund's average daily net assets of 0.45% on assets up to $250 million, 0.40%
on assets from $250 million to $500 million and 0.35% on assets in excess of
$500 million.

(B) DISTRIBUTION, SERVICE AND SHAREHOLDER SERVICE FEES.  The Trust, on behalf of
the Fund, has a Distribution Agreement with NYLIFE Distributors LLC ("the
Distributor"), an indirect wholly-owned subsidiary of New York Life. The Fund,
with respect to Class A, Class B, Class C and Class R2 shares, has adopted
distribution plans (the "Plans") in accordance with the provisions of Rule 12b-1
under the 1940 Act. Pursuant to the Class A and Class R2 Plans, the Distributor
receives a monthly fee from the Fund at an annual rate of 0.25% of the average
daily net assets of the Fund's Class A and Class R2 shares, which is an expense
of the Class A and Class R2 shares of the Fund for distribution or service
activities as designated by the Distributor. Pursuant to the Class B and Class C
Plans, the Fund pays the Distributor a monthly fee, which is an expense of the
Class B and Class C shares of the Fund, at the annual rate of 0.75% of the
average daily net assets of the Fund's Class B and Class C shares. The
Distribution Plans provide that the Class B and Class C shares of the Fund 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 Fund. Class I shares and Class R1
shares are not subject to a distribution or service fee.

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

The Fund has adopted a shareholder services plan with respect to Class R1 and R2
shares. Under the terms of this plan, Class R1 and Class R2 shares are
authorized to pay to NYLIM, its affiliates, or independent third-party
providers, as compensation for services rendered, a shareholder service fee at
the rate of 0.10% of the average daily net assets of the Fund's Class R1 and R2
shares.

(C) SALES CHARGES.  The Fund was advised by the Distributor that the amount of
sales charges retained on sales of Class A Fund shares was $198,745 for the year
ended October 31, 2004. The Fund was also advised that the Distributor retained
contingent deferred sales charges on redemption of Class A, Class B and Class C
shares of $16,327, $392,114 and $27,307, respectively, for the year ended
October 31, 2004.

(D) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT.  NYLIM
Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's
transfer, dividend disbursing and shareholder servicing agent. NYLIM Service has
entered into an agreement with Boston Financial Data Services ("BFDS") pursuant
to which BFDS will perform certain of the services for which NYLIM Service is
responsible. Transfer agent expenses for the year ended October 31, 2004
amounted to $2,313,877.

(E) NON-INTERESTED TRUSTEES FEES.  Non-Interested Trustees are paid an annual
retainer fee of $45,000, $2,000 for each Board meeting, $1,000 for each
Committee meeting and $500 for each Valuation Subcommittee telephonic meeting
attended plus reimbursement for travel and out-of-pocket expenses. The Lead
Non-Interested Trustee is also paid an annual retainer fee of $20,000. The Audit
Committee Chairman receives an additional $2,000 for each meeting of the Audit
Committee attended and the Chairpersons of the Brokerage Committee, Operations
Committee and Performance Committee each receive an additional $1,000 for each
meeting of the Brokerage Committee, Operations Committee and Performance
Committee attended, respectively. In addition, each Non-Interested Trustee is
paid $1,000 for attending meetings of the Non-Interested Trustees held in
advance of or in connection with Board/Committee meetings. The Trust allocates
trustees fees in proportion to the net assets of the respective Funds. Thus the
MAP Fund only pays a portion of the fees identified above.

(F) OTHER.  Fees for the cost of legal services, included in Professional fees
as shown on the Statement of Operations, provided to the Fund by the Office of
the General Counsel of NYLIM amounted to $27,419 for the year ended October 31,
2004.

The Fund pays the Manager a monthly fee for recordkeeping services provided
under the Accounting Agreement at the annual rate of 1/20 of 1% for the first
$20 million of average monthly net assets, 1/30 of 1% of the next $80 million of
average monthly net assets and 1/100 of 1%

 24   MainStay MAP Fund


of any amount in excess of $100 million of average monthly net assets. Fees for
recordkeeping services provided to the Fund by the Manager amounted to $112,916
for the year ended October 31, 2004.

NOTE 4 -- CUSTODIAN:
The Bank of New York is custodian of cash and securities of the Fund. Custodial
fees are charged to the Fund based on the market value of securities in the Fund
and the number of certain cash transactions incurred by the Fund.

NOTE 5 -- FEDERAL INCOME TAX:
As of October 31, 2004, the components of accumulated gain on a tax basis were
as follows:

<Table>
<Caption>
   ACCUMULATED                        TOTAL
     CAPITAL        UNREALIZED     ACCUMULATED

   $42,033,440     $112,729,864    $154,763,304
</Table>

The difference between book-basis and tax-basis unrealized appreciation is
primarily due to wash sale deferrals and real estate investment trust
distributions.

The Fund utilized $42,290,239 of capital loss carryforward during the year ended
October 31, 2004.

The tax character of distributions paid during the year ended October 31, 2004,
the ten months ended October 31, 2003 and the year ended December 31, 2002,
shown in the Statement of Changes in Net Assets, was as follows:

The Fund and certain affiliated funds maintain a line of credit of $160,000,000
with a syndicate of banks in order to secure a source of funds for temporary
purposes to meet unanticipated or excessive shareholder redemption requests. The

amount, regardless of usage, to The Bank of New York, which acts as agent to the
syndicate. Such commitment fees are allocated among the funds based upon net
assets and other factors. Interest on any revolving credit loan is charged based

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

NOTE 9 -- OTHER MATTERS:

NYLIM and mutual funds that NYLIM advises have received requests for information
from various government authorities and regulatory bodies regarding market
timing, late trading, operations, fees, expenses, and other matters. NYLIM and
the funds it advises are cooperating fully in responding to these requests. As
reported in response to those requests for information, NYLIM was previously
party to agreements with certain registered representatives of broker-dealers
relating to the level of trading by clients or customers of those registered
representatives in shares of certain funds of the Trust. NYLIM is continuing to
review what effect, if any, transactions under these agreements may have had on
the funds, and will continue to apprise the Board of Trustees of such
information. NYLIM does not believe at this time that such trading had any
material effect on the funds' financial statements or their shareholders. To
date, substantially all of the costs associated with these and other regulatory
matters have been borne by NYLIM. Except as described below, neither NYLIM nor
the funds advised by it have any reason to believe that they have been targeted
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.
Discussions have been held with the SEC concerning a possible resolution of this
matter. These discussions are continuing, but there can be no assurance at this
time as to the outcome of these efforts.

NOTE 10 -- CHANGE IN INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM (UNAUDITED):

On March 8, 2004, KPMG LLP ("KPMG") was selected as the Trust's independent
auditor for the 2004 fiscal year. The selection of KPMG was recommended by the
Trust's Audit Committee, comprised of all Non-Interested Trustees, and was
approved by the Trust's Board of Trustees.

The predecessor independent auditor's reports on the Trust's financial
statements for the period ended October 31, 2003 and year ended December 31,
2002 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 periods, and through the date of engagement of KPMG, there
were no disagreements between 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 periods.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Trustees and Shareholders of
The MainStay Funds:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of the MainStay MAP Fund (the "Fund"), one of the
funds constituting The MainStay Funds, as of October 31, 2004, and the related
statement of operations, statement of changes in net assets and the financial
highlights for the year or period then ended. These financial statements and
financial highlights are the responsibility of the Fund's management. Our
responsibility is to express an opinion on these financial statements and
financial highlights based on our audit. The statement of changes in net assets
for the period ended October 31, 2003 and the year ended December 31, 2002, and
the financial highlights for the periods presented through October 31, 2003,
were audited by other auditors, whose report dated December 18, 2003 expressed
an unqualified opinion thereon.

We conducted our audit in accordance with the Standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
also includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2004 by correspondence with the custodian and
brokers. As to securities purchased or sold but not yet received or delivered,
we performed other appropriate auditing procedures. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
MainStay MAP Fund of The MainStay Funds as of October 31, 2004, the results of
its operations, the changes in its net assets and its financial highlights for
the year or period then ended, in conformity with U.S. generally accepted
accounting principles.

ITEM 2. CODE OF ETHICS.

      As of the end of the period covered by this report, the Registrant has
adopted a code of ethics (the "Code") that applies to the Registrant's principal
executive office ("PEO") and principal financial officer ("PFO"). There were no
amendments to the Code during the period covered by the report. The Registrant
did not grant any waivers, including implicit waivers, from any provisions of
the Code to the PEO or PFO during the period covered by this report.

ITEM 3. AUDIT COMMITTEE FINANCIAL EXPERT.

The Board of Trustees has determined that its Audit Committee does not currently
have any member that qualifies as an "audit committee financial expert" as
defined under rules adopted by the Securities and Exchange Commission. In
accordance the authority granted under the Registrant's Audit Committee Charter,
the Audit Committee has retained a third party consultant to provide the
Committee and the Registrant with the financial expertise, knowledge and skills
similar to those of an audit committee financial expert.

ITEM 4. PRINCIPAL ACCOUNTANT FEES AND SERVICES.

(a) Audit Fees

The aggregate fees billed for the fiscal year ended October 31, 2004 for
professional services rendered by KPMG LLP ("KPMG") for the audit of the
Registrant's annual financial statements or services that are normally provided
by KPMG in connection with statutory and regulatory filings or engagements for
that fiscal year were $820,000. The aggregate fees billed for the fiscal period
ended October 31, 2003 for professional services rendered by
PricewaterhouseCoopers LLP ("PWC") for the audit of the Registrant's annual
financial statements or services that were normally provided by the PWC in
connection with statutory and regulatory filings or engagements for that fiscal
years were $782,662.

(b) Audit Related Fees

       The aggregate fees billed for the fiscal year ended October 31, 2004 for
assurance and related services by KPMG that are reasonably related to the
performance of the audit of the Registrant's financial statements and are not
reported under paragraph (a) of this Item were $7,500. The aggregate fees billed
for the fiscal year ended October 31, 2004 for assurance and related services by
PWC that are reasonably related to the performance of the audit of the
Registrant's financial statements and are not reported under paragraph (a) of
this Item were $8,000. The aggregate fees billed for the fiscal period ended
October 31, 2003 for assurance and related services by PWC that are reasonably
related to the performance of the audit of the Registrant's financial statements
and are not reported under paragraph (a) of this Item were $6,000.

(c) Tax Fees

The aggregate fees billed: (i) during the fiscal year ended October 31, 2004 for
professional services rendered by KPMG for tax compliance, tax advice, and tax
planning were $116,000 and (ii) during the fiscal period ended October 31, 2003
for professional services rendered by PWC for tax compliance, tax advice, and
tax planning were $151,300. These services primarily included preparation of



federal, state and local income tax returns. Additionally, services included the
preparation of excise tax returns and excise tax distribution requirements.

(d) All Other Fees

The aggregate fees billed: (i) during the fiscal year ended October 31, 2004 for
products and services provided by KPMG, other than the services reported in
paragraphs (a) through (c) of this Item were $0 and (ii) during the fiscal
period ended October 31, 2003 for products and services provided by PWC, other
than the services reported in paragraphs (a) through (c) of this Item were $0.

(e) Pre-Approval Policies and Procedures

(1) The Registrant's Audit Committee has adopted pre-approval policies and
procedures (the "Procedures") to govern the Committee's pre-approval of (i) all
audit services and permissible non-audit services to be provided to the
Registrant by its independent accountant, and (ii) all permissible non-audit
services to be provided by such independent accountant to the Registrant's
investment adviser and to any entity controlling, controlled by or under common
control with the investment adviser that provides ongoing services to the
Registrant (collectively, the "Service Affiliates") if the services directly
relate to the Registrant's operations and financial reporting. In accordance
with the Procedures, the Audit Committee is responsible for the engagement of
the independent accountant to certify the Registrant's financial statements for
each fiscal year. With respect to the pre-approval of non-audit services
provided to the Registrant and its Service Affiliates, the Procedures provide
that the Audit Committee may annually pre-approve a list of the types of
services that may be provided to the Registrant or its Service Affiliates, or
the Audit Committee may pre-approve such services on a project-by-project basis
as they arise. Unless a type of service has received general pre-approval, it
will require specific pre-approval by the Audit Committee if it is to be
provided by the independent accountant. The Procedures also permit the Audit
Committee to delegate authority to one or more of its members to pre-approve any
proposed non-audit services that have not been previously pre-approved by the
Audit Committee, subject to the ratification by the full Audit Committee no
later than its next scheduled meeting. To date, the Audit Committee has not
delegated such authority.

(2) With respect to the services described in paragraphs (b) through (d) of this
Item 4, no amount was approved by the Audit Committee pursuant to paragraph
(c)(7)(i)(C) of Rule 2-01 of Regulation S-X.

(f) There were no hours expended on KPMG's engagement to audit the Registrant's
financial statements for the most recent fiscal year attributable to work
performed by persons other than KPMG's full-time, permanent employees.

(g) All non-audit fees billed by (i) KPMG for services rendered to the
Registrant for the fiscal year ended October 31, 2004 and (ii) PWC for services
rendered to the Registrant for the fiscal period ended October 31, 2003 are
disclosed in 4(b)-(d) above.

The aggregate non-audit fees billed by (i) KPMG for the year ended October 31,
2004 for services rendered to the Registrant's investment adviser (not including
any sub-adviser whose role is primarily portfolio management and is
subcontracted with or overseen by another investment adviser), and any entity
controlling, controlled by, or under common control with the adviser that
provides ongoing services to the Registrant were approximately $0 and
(ii) PWC for the fiscal period ended October 31,



2003 for services rendered to the Registrant's investment adviser (not including
any sub-adviser whose role is primarily portfolio management and is
subcontracted with or overseen by another investment adviser), and any entity
controlling, controlled by, or under common control with the adviser that
provides ongoing services to the Registrant were approximately $0.

(h) The Registrant's Audit Committee has determined that the non-audit services
rendered by (i) KPMG for the fiscal year ended October 31, 2004 and (ii) PWC for
the fiscal period ended October 31, 2003 to the Registrant's investment adviser
and any entity controlling, controlled by, or under common control with the
Registrant's investment adviser that provides ongoing services to the Registrant
that were not required to be pre-approved by the Audit Committee because they
did not relate directly to the operations and financial reporting of the
registrant were compatible with maintaining the respective independence of KPMG
and PWC during the relevant time periods.

      Not applicable.

ITEM 6. SCHEDULE OF INVESTMENTS

ITEM 9. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.

      At a meeting held on December 10-11, 2004, the Nominating Committee of the
Registrant adopted policies for considering Board Member candidates. The
Committee may consider nominations from shareholders of the Registrant. Each
eligible shareholder or shareholder group may submit no more than one candidate

the Registrant's Secretary.

      A shareholder's submission to the Secretary of the Registrant must

the vote; (ii) shared power to vote or direct the vote; (iii) sole power to

dispose or direct the disposition of such shares. In addition the certification
shall provide that the shares have been held continuously for at least two years
as of the date of the nomination; (c) the candidate's contact information and
the number of applicable Registrant shares owned by the candidate; (d) all
information regarding the candidate that would be required to be disclosed in
solicitations of proxies for elections of trustees required by Regulation 14A
under the Securities Exchange Act of 1934, as amended; and (e) a notarized
letter executed by the candidate, stating his or her intention to serve as a



candidate and be named in the Registrant's proxy statement, if so designated by
the Nominating Committee and the Registrant's Board.

      It shall be in the Nominating Committee's sole discretion whether to seek
corrections of a deficient submission or to exclude a candidate from
consideration.

ITEM 10. CONTROLS AND PROCEDURES.

(a)   Based on an evaluation of the Disclosure Controls and Procedures (as
defined in Rule 30a-3(c) under the Investment Company Act of 1940, the
"Disclosure Controls") as of a date within 90 days prior to the filing date (the
"Filing Date") of this Form N-CSR (the "Report"), the Registrant's principal
executive officer and principal financial officer have concluded that the
Disclosure Controls are reasonably designed to ensure that information required
to be disclosed by the Registrant in the Report is recorded, processed,
summarized and reported by the Filing Date, including ensuring that information
required to be disclosed in the Report is accumulated and communicated to the
Registrant's management, including the Registrant's principal executive officer
and principal financial officer, as appropriate to allow timely decisions
regarding required disclosure.

(b)   There were no changes in the Registrant's internal control over financial
reporting (as defined in Rule 30a-3(d) under the Investment Company Act of 1940
that occurred during the second fiscal quarter of the period covered by this
report that has materially affected, or is reasonably likely to materially
affect, the Registrant's internal control over financial reporting.
