Morgan Stanley Dean Witter S&P 500 Index Fund Two World Trade Center,
Letter to the Shareholders August 31, 2000 New York, New York 10048
DEAR SHAREHOLDER:
After a series of interest-rate hikes this spring by the Federal Reserve Board,
the U.S. economy finally seems to be slowing to a lower but more sustainable
growth rate. As a result, many of the trends that were established in 1999 have
been reversed in 2000. Mid-cap companies, as represented by the S&P MidCap 400
Index, outperformed large-cap companies, as reflected by the Standard & Poor's
500 Stock Index (S&P 500), 23.04 percent to 4.10 percent, respectively, over
the first eight months of 2000. The technology sector, a favorite of the market
in 1999, has taken a back seat to more defensive sectors like utilities and
health care. Despite its modest return thus far in 2000, the S&P 500's recent
performance compares favorably to that of other widely followed benchmarks such
as the Nasdaq Composite Index and the Dow Jones Industrial Average.
PERFORMANCE
For the 12-month period ended August 31, 2000, Morgan Stanley Dean Witter S&P
500 Index Fund's Class B shares returned 14.69 percent compared to 16.31
percent for the S&P 500. During the same period, the Fund's Class A, C and D
shares posted total returns of 15.49 percent, 14.69 percent and 15.81 percent,
respectively. The performance of the Fund's four share classes varies because
each class has different expenses. The total return figures given assume the
reinvestment of all distributions but do not reflect the deduction of any
applicable sales charges. The accompanying chart compares the Fund's
performance to that of the S&P 500.
The Fund seeks to deliver investment performance that corresponds, before
expenses, to the total return of the S&P 500 by investing in stocks that make
up the S&P 500 in approximately the same weightings as they are represented in
the index. The fully invested, broadly diversified Fund also seeks to minimize
turnover to generate tax-efficient returns.

LOOKING AHEAD
As the fear of near-term interest-rate hikes subsides, market watchers now
wonder if earnings growth can meet the expectations that have been priced into
the market. Many of the large-cap blue-chip companies that have significant
overseas operations have recently come under pressure from the falling euro.
However, signs do not point to the U.S. economy slowing too much but rather
maintaining a healthier, more sustainable growth rate. Additionally, high
productivity and low labor costs are helping to buoy corporate earnings.
We appreciate your ongoing support of Morgan Stanley Dean Witter S&P 500 Index
Fund and look forward to continuing to serve your investment needs.
Very truly yours,
/s/ Charles A. Fiumefreddo /s/ Mitchell M. Merin

Past performance is not predictive of future returns. Investment return and
principal value will fluctuate. When you sell fund shares, they may be worth
more or less than their original cost. Performance for Class A, Class B, Class
C, and Class D shares will vary due to differences in sales charges and
expenses.

Morgan Stanley Dean Witter S&P 500 Index Fund
Notes to Financial Statements August 31, 2000
1. ORGANIZATION AND ACCOUNTING POLICIES
Morgan Stanley Dean Witter S&P 500 Index Fund (the "Fund") is registered under
the Investment Company Act of 1940, as amended (the "Act"), as a diversified,
open-end management investment company. The Fund's investment objective is to
provide investment results that, before expenses, correspond to the total
return of the Standard & Poor's 500 Composite Stock Price Index (the "S&P 500
Index"). The Fund seeks to achieve its objective by investing at least 80% of
its total assets in common stocks included in the S&P 500 Index in
approximately the same weighting as the Index. The Fund was organized as a
Massachusetts business trust on June 18, 1997 and commenced operations on
September 26, 1997.
The Fund offers Class A shares, Class B shares, Class C shares and Class D
shares. The four classes are substantially the same except that most Class A
shares are subject to a sales charge imposed at the time of purchase and some
Class A shares, and most Class B shares and Class C shares are subject to a
contingent deferred sales charge imposed on shares redeemed within one year,
six years and one year, respectively. Class D shares are not subject to a sales
charge. Additionally, Class A shares, Class B shares and Class C shares incur
distribution expenses.
The preparation of financial statements in accordance with generally accepted
accounting principles requires management to make estimates and assumptions
that affect the reported amounts and disclosures. Actual results could differ
from those estimates.
The following is a summary of significant accounting policies:
A. VALUATION OF INVESTMENTS - (1) an equity portfolio security listed or traded
on the New York or American stock exchange, NASDAQ, or other exchange is valued
at its latest sale price, prior to the time when assets are valued; if there
were no sales that day, the security is valued at the latest bid price (in
cases where a security is traded on more than one exchange, the security is
valued on the exchange designated as the primary market pursuant to procedures
adopted by the Trustees); (2) all other portfolio securities for which
over-the-counter market quotations are readily available are valued at the
latest available bid price; (3) when market quotations are not readily
available, including circumstances under which it is determined by Morgan
Stanley Dean Witter Advisors Inc. (the "Investment Manager") that sale or bid
prices are not reflective of a security's market value, portfolio securities
are valued at their fair value as determined in good faith under procedures
established by and under the general supervision of the Trustees (valuation of
debt securities for which market quotations are not readily available may be
based upon current market prices of securities which are comparable in coupon,
rating and maturity or an appropriate matrix utilizing similar factors); and
(4) short-term debt securities having a maturity date of
16
<PAGE>
Morgan Stanley Dean Witter S&P 500 Index Fund
Notes to Financial Statements August 31, 2000, continued
more than sixty days at time of purchase are valued on a mark-to-market basis
until sixty days prior to maturity and thereafter at amortized cost based on
their value on the 61st day. Short-term debt securities having a maturity date
of sixty days or less at the time of purchase are valued at amortized cost.
B. ACCOUNTING FOR INVESTMENTS - Security transactions are accounted for on the
trade date (date the order to buy or sell is executed). Realized gains and
losses on security transactions are determined by the identified cost method.
Dividend income and other distributions are recorded on the ex-dividend date.
Discounts are accreted over the life of the respective securities. Interest
income is accrued daily.
C. MULTIPLE CLASS ALLOCATIONS - Investment income, expenses (other than
distribution fees), and realized and unrealized gains and losses are allocated
to each class of shares based upon the relative net asset value on the date
such items are recognized. Distribution fees are charged directly to the
respective class.
D. FUTURES CONTRACTS - A futures contract is an agreement between two parties
to buy and sell financial instruments at a set price on a future date. Upon
entering into such a contract, the Fund is required to pledge to the broker
cash, U.S. Government securities or other liquid portfolio securities equal to
the minimum initial margin requirements of the applicable futures exchange.
Pursuant to the contract, 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
which is known as variation margin. Such receipts or payments are recorded by
the Fund as unrealized gains or losses. Upon closing of the contract, the Fund
realizes a gain or loss equal to the difference between the value of the
contract at the time it was opened and the value at the time it was closed.
E. FEDERAL INCOME TAX STATUS - It is the Fund's policy to comply with the
requirements of the Internal Revenue Code applicable to regulated investment
companies and to distribute all of its taxable income to its shareholders.
Accordingly, no federal income tax provision is required.
F. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS - The Fund records dividends and
distributions to its shareholders on the ex-dividend date. The amount of
dividends and distributions from net investment income and net realized capital
gains 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. Dividends and
distributions which exceed net investment income and net realized capital gains
for tax purposes are reported as distributions of paid-in-capital.

Morgan Stanley Dean Witter S&P 500 Index Fund
Notes to Financial Statements August 31, 2000, continued
G. ORGANIZATIONAL EXPENSES - The Investment Manager incurred the organizational
expenses of the Fund in the amount of approximately $68,000 which have been
reimbursed by the Fund for the full amount thereof. Such expenses have been
deferred and are being amortized on the straight-line method over a period not
to exceed five years from the commencement of operations.
2. INVESTMENT MANAGEMENT AGREEMENT
Pursuant to an Investment Management Agreement, the Fund pays the Investment
Manager a management fee, accrued daily and payable monthly, by applying the
following annual rates to the net assets of the Fund determined as of the close
of each business day: 0.40% of the portion of daily net assets not exceeding
$1.5 billion; 0.375% to the portion of daily net assets exceeding $1.5 billion
but not exceeding $3 billion; and 0.35% of the portion of daily net assets in
excess of $3 billion.
The Investment Manager has agreed to assume all operating expenses (except for
Plan of Distribution fees) and to waive the compensation provided for in its
Investment Management Agreement to the extent that such expenses and
compensation on an annualized basis exceed 0.50% of the daily net assets of the
Fund.
3. PLAN OF DISTRIBUTION
Shares of the Fund are distributed by Morgan Stanley Dean Witter Distributors
Inc. (the "Distributor"), an affiliate of the Investment Manager. The Fund has
adopted a Plan of Distribution (the "Plan") pursuant to Rule 12b-1 under the
Act. The Plan provides that the Fund will pay the Distributor a fee which is
accrued daily and paid monthly at the following annual rates: (i) Class A - up
to 0.25% of the average daily net assets of Class A; (ii) Class B - 1.0% of the
average daily net assets of Class B; and (iii) Class C - up to 1.0% of the
average daily net assets of Class C.
In the case of Class B shares, provided that the Plan continues in effect, any
cumulative expenses incurred by the Distributor but not yet recovered may be
recovered through the payment of future distribution fees from the Fund
pursuant to the Plan and contingent deferred sales charges paid by investors
upon redemption of Class B shares. Although there is no legal obligation for
the Fund to pay expenses incurred in excess of payments made to the Distributor
under the Plan and the proceeds of contingent deferred sales charges paid by
investors upon redemption of shares, if for any reason the Plan is terminated,
the Trustees will consider at that time the manner in which to treat such
expenses. The Distributor has advised the Fund that such excess amounts totaled
$53,054,813 at August 31, 2000.
In the case of Class A shares and Class C shares, expenses incurred pursuant to
the Plan in any calendar year in excess of 0.25% or 1.0% of the average daily
net assets of Class A or Class C, respectively, will
18

Morgan Stanley Dean Witter S&P 500 Index Fund
Notes to Financial Statements August 31, 2000, continued
not be reimbursed by the Fund through payments in any subsequent year, except
that expenses representing a gross sales credit to Morgan Stanley Dean Witter
Financial Advisors or other selected broker-dealer representatives may be
reimbursed in the subsequent calendar year. For the year ended August 31, 2000,
the distribution fee was accrued for Class A shares and Class C shares at the

7. PURPOSES OF AND RISKS RELATING TO CERTAIN FINANCIAL INSTRUMENTS
The Fund may purchase and sell stock index futures ("futures contracts") for
the following reasons: to simulate full investment in the S&P 500 Index while
retaining a cash balance for fund management purposes; to facilitate trading;
to reduce transaction costs; or to seek higher investment returns when a
futures contract is priced more attractively than stocks comprising the S&P 500
Index.
These futures contracts involve elements of market risk in excess of the amount
reflected in the Statement of Assets and Liabilities. The Fund bears the risk
of an unfavorable change in the value of the underlying securities.
At August 31, 2000, the Fund had outstanding futures contracts.

Report of Independent Accountants
TO THE SHAREHOLDERS AND BOARD OF TRUSTEES OF
MORGAN STANLEY DEAN WITTER S&P 500 INDEX FUND:
We have audited the accompanying statement of assets and liabilities of Morgan
Stanley Dean Witter S&P 500 Index Fund (the "Fund"), including the portfolio of
investments, as of August 31, 2000, and the related statements of operations
and 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 year ended August 31,
1999 and the financial highlights for each of the respective stated periods
ended August 31, 1999 were audited by other independent accountants whose
report, dated October 11, 1999, expressed an unqualified opinion on that
statement and financial highlights.
We conducted our audit in accordance with auditing standards generally accepted
in the United States of America. Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit 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
August 31, 2000, by correspondence with the custodian and brokers. 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
Morgan Stanley Dean Witter S&P 500 Index Fund as of August 31, 2000, the
results of its operations, the changes in its net assets, and the financial
highlights for the year then ended, in conformity with accounting principles
generally accepted in the United States of America.

Change in Independent Accountants
On July 1, 2000 PricewaterhouseCoopers LLP resigned as independent accountants
of the Fund.
The reports of PricewaterhouseCoopers LLP on the financial statements of the
Fund for the past two fiscal years contained no adverse opinion or disclaimer
of opinion and were not qualified or modified as to uncertainty, audit scope or
accounting principle.
In connection with its audits for the two most recent fiscal years and through
July 1, 2000, there have been no disagreements with PricewaterhouseCoopers LLP
on any matter of accounting principles or practices, financial statement
disclosure, or auditing scope or procedure, which disagreements if not resolved
to the satisfaction of PricewaterhouseCoopers LLP would have caused them to
make reference thereto in their report on the financial statements for such
years.
The Fund, with the approval of its Board of Trustees and its Audit Committee,
engaged Deloitte & Touche LLP as its new independent accountants as of July 1,
2000.
