THE PERFORMANCE OF THE FUND'S FOUR SHARE CLASSES VARIES BECAUSE EACH HAS
DIFFERENT EXPENSES. THE FUND'S TOTAL RETURN FIGURES ASSUME THE REINVESTMENT OF
ALL DISTRIBUTIONS, BUT DO NO REFLECT THE DEDUCTION OF ANY APPLICABLE SALES
CHARGES. SUCH COSTS WOULD LOWER PERFORMANCE. PAST PERFORMANCE IS NO GUARANTEE OF
FUTURE RESULTS. SEE PERFORMANCE SUMMARY FOR STANDARDIZED PERFORMANCE
INFORMATION.

MARKET CONDITIONS

Throughout the fiscal year ended July 31, 2003, economic conditions in the
United States and around the world remained weak, with GDP growth averaging
about 2 percent. During the first half of the fiscal year investor confidence
wavered due to concerns about corporate governance and the perceived lack of
balance-sheet integrity. During the second half, investor sentiment was
initially dampened by geopolitical tensions leading up to the war in Iraq.
Beginning in March, the market rallied sharply as investors began to discount a
rebound in the global economy due to accommodative fiscal and monetary policy.
Credit spreads tightened meaningfully.

As a result, the markets ended the first half of calendar year 2003 with gains,
the first time this has occurred since 1999. The best performing groups included
cyclical sectors such as technology and consumer cyclicals and beneficiaries of
looser financial conditions such as the electric power companies.

PERFORMANCE ANALYSIS

The Fund's underperformance is largely due to its generally conservative
construction. The Fund was held back by its continued focus on high quality
companies that were outpaced by more speculative companies during the period.
The Fund did benefit from its exposure to healthcare, particularly medical
devices and biotechnology, which are enjoying strong new product cycles. The
Fund also benefited from its exposure to wireless telecommunications providers,
as the leaders enjoyed gains in market share and margin improvement.

MORGAN STANLEY AGGRESSIVE EQUITY FUND
NOTES TO FINANCIAL STATEMENTS - JULY 31, 2003

1. ORGANIZATION AND ACCOUNTING POLICIES
Morgan Stanley Aggressive Equity 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
capital growth. The Fund seeks to achieve its objective by primarily investing
in equity securities of U.S. or foreign companies that offer the potential for
superior earnings growth. The Fund was organized as a Massachusetts business
trust on October 29, 1997 and commenced operations on February 24, 1999.

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 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 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 mean between the last reported bid
and asked price; (2) an equity portfolio security listed or traded on the Nasdaq
is valued at the Nasdaq Official Closing Price; if there were no sales that day,
the security is valued at the mean between the last reported bid and asked
price; (3) all other equity portfolio securities for which over-the-counter
market quotations are readily available are valued at the mean between the last
reported bid and asked 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; (4) for equity securities traded on foreign exchanges, the last reported
sale price or the latest bid price may be used if there were no sales on a
particular day; (5) futures are valued at the latest price published by the
commodities exchange on which they trade; (6) when market quotations are not
readily available or Morgan Stanley Investment Advisors Inc. (the "Investment
Manager") determines that the latest sale price, the bid price or the mean
between the last reported bid and asked price do not reflect 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
Fund's Trustees; (7) certain portfolio securities may be valued by an outside
pricing service approved by the Fund's Trustees; and (8) short-term debt
securities having a maturity date of 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.

                                       15
<Page>

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 and premiums are amortized over the life of the
respective securities. Interest income is accrued daily.

C. REPURCHASE AGREEMENTS -- Pursuant to an Exemptive Order issued by the
Securities and Exchange Commission, the Fund, along with other affiliated
entities managed by the Investment Manager, may transfer uninvested cash
balances into one or more joint repurchase agreement accounts. These balances
are invested in one or more repurchase agreements and are collateralized by
cash, U.S. Treasury or federal agency obligations. The Fund may also invest
directly with institutions in repurchase agreements. The Fund's custodian
receives the collateral, which is marked-to-market daily to determine that the
value of the collateral does not decrease below the repurchase price plus
accrued interest.

D. 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.

E. FOREIGN CURRENCY TRANSLATION AND FORWARD FOREIGN CURRENCY CONTRACTS -- The
books and records of the Fund are maintained in U.S. dollars as follows: (1) the
foreign currency market value of investment securities, other assets and
liabilities and forward foreign currency contracts ("forward contracts") are
translated at the exchange rates prevailing at the end of the period; and (2)
purchases, sales, income and expenses are translated at the exchange rates
prevailing on the respective dates of such transactions. The resultant exchange
gains and losses are recorded as realized and unrealized gain/loss on foreign
exchange transactions. Pursuant to U.S. Federal income tax regulations, certain
foreign exchange gains/losses included in realized and unrealized gain/loss are
included in or are a reduction of ordinary income for federal income tax
purposes. The Fund does not isolate that portion of the results of operations
arising as a result of changes in the foreign exchange rates from the changes in
the market prices of the securities. Forward contracts are valued daily at the
appropriate exchange rates. The resultant unrealized exchange gains and losses
are recorded as unrealized foreign currency gain or loss. The Fund records
realized gains or losses on delivery of the currency or at the time the forward
contract is extinguished (compensated) by entering into a closing transaction
prior to delivery.

F. FUTURES CONTRACTS -- A futures contract is an agreement between two parties
to buy and sell financial instruments or contracts based on financial indices 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. Such receipts or payments known as

                                       16
<Page>

variation margin are recorded by the Fund as unrealized gains and 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.

G. FEDERAL INCOME TAX POLICY -- It is the Fund's policy to comply with the
requirements of the Internal Revenue Code applicable to regulated investment
companies and to distribute substantially all of its taxable income to its
shareholders. Accordingly, no federal income tax provision is required.

H. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS -- Dividends and distributions to
shareholders are recorded on the ex-dividend date.

I. USE OF ESTIMATES -- 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.

2. INVESTMENT MANAGEMENT AGREEMENT
Pursuant to an Investment Management Agreement, the Fund pays 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: 0.75% to
the portion of daily net assets not exceeding $2 billion; and 0.725% to the
portion of daily net assets exceeding $2 billion.

3. PLAN OF DISTRIBUTION
Shares of the Fund are distributed by Morgan Stanley 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
$27,086,041 at July 31, 2003.

                                       17

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 not be reimbursed by the
Fund through payments in any subsequent year, except that expenses representing
a gross sales credit to Morgan Stanley Financial Advisors or other selected
broker-dealer representatives may be reimbursed in the subsequent calendar year.
For the year ended July 31, 2003, the distribution fee was accrued for Class A
shares and Class C shares at the annual rate of 0.25% and 1.0%, respectively.

The Distributor has informed the Fund that for the year ended July 31, 2003, it
received contingent deferred sales charges from certain redemptions of the
Fund's Class A shares, Class B shares and Class C shares of $15, $1,158,423 and
$3,429, respectively and received $29,595 in front-end sales charges from sales
of the Fund's Class A shares. The respective shareholders pay such charges which
are not an expense of the Fund.

4. SECURITY TRANSACTIONS AND TRANSACTIONS WITH AFFILIATES
The cost of purchases and proceeds from sales of portfolio securities, excluding
short-term investments, for the year ended July 31, 2003 aggregated
$1,179,775,039 and $1,313,388,673, respectively. Included in the aforementioned

$30,853,734, respectively and purchases and sales with other Morgan Stanley
Funds $876,557 and $1,274,714, respectively including a net realized loss of
$116,999.

For the year ended July 31, 2003, the Fund incurred brokerage commissions of
$304,240 with Morgan Stanley & Co., Inc., an affiliate of the Investment Manager
and Distributor, for portfolio transactions executed on behalf of the Fund. At
July 31, 2003, the Fund's receivable for investments sold included unsettled
trades with Morgan Stanley & Co., Inc. of $3,806,499.

Morgan Stanley Trust, an affiliate of the Investment Manager and Distributor, is
the Fund's transfer agent. At July 31, 2003, the Fund had transfer agent fees
and expenses payable of approximately $12,300.

5. FEDERAL INCOME TAX STATUS

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

                                       18
<Page>

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.

As of July 31, 2003, the tax-basis components of accumulated losses were as
follows:

<Table>
                                              
Net accumulated earnings                                     --

Post-October losses                                 (21,746,710)
Net unrealized appreciation                          37,129,138
                                                 --------------

Total accumulated losses                         $ (471,700,162)
                                                 ==============
</Table>

*As of July 31, 2003, the Fund had a net capital loss carryforward of
$487,082,590 of which $366,027,253 will expire on July 31, 2010 and $121,055,337
will expire on July 31, 2011 to offset future capital gains to the extent
provided by regulations.

As of July 31, 2003, the Fund had temporary book/tax differences primarily
attributable to post-October losses (capital losses incurred after October 31
within the taxable year which are deemed to arise on the first business day of
the Fund's next taxable year) and capital loss deferrals on wash sales and
permanent book/tax differences primarily attributable to a net operating loss.
To reflect reclassifications arising from the permanent differences,
paid-in-capital was charged $4,980,373, accumulated net investment loss was
credited $4,980,174 and accumulated net realized loss was credited $199.

6. PURPOSES OF AND RISKS RELATING TO CERTAIN FINANCIAL INSTRUMENTS
The Fund may enter into forward contracts to facilitate settlement of foreign
currency denominated portfolio transactions or to manage foreign currency
exposure associated with foreign currency denominated securities.

To hedge against adverse interest rate, foreign currency and market risks, the
Fund may purchase and sell interest rate, currency and index futures ("futures
contracts").

Forward contracts and 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 foreign exchange rates
underlying the forward contracts. Risks may also rise upon entering into these
contracts from the potential inability of the counterparties to meet the terms
of their contracts.

At July 31, 2003, the Fund had outstanding forward and futures contracts.

MORGAN STANLEY AGGRESSIVE EQUITY FUND
INDEPENDENT AUDITORS' REPORT


To the Shareholders and Board of Trustees of
Morgan Stanley Aggressive Equity Fund:

We have audited the accompanying statement of assets and liabilities of Morgan
Stanley Aggressive Equity Fund (the "Fund"), including the portfolio of
investments, as of July 31, 2003, and the related statements of operations for
the year then ended and changes in net assets for each of the two years in the
period then ended, and the financial highlights for each of the periods
presented. 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
audits.

We conducted our audits 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 and financial highlights 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 July 31, 2003, 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 audits provide 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 Aggressive Equity Fund as of July 31, 2003, the results of its
operations for the year then ended, the changes in its net assets for each of
the two years in the period then ended, and the financial highlights for each of
the periods presented, in conformity with accounting principles generally
accepted in the United States of America.

Item 3.  Audit Committee Financial Expert.

The Fund's Board of Trustees has determined that it has two "audit committee
financial experts" serving on its audit committee, each of whom are
"independent" Trustees: Dr. Manuel H. Johnson and Joseph J. Kearns. Under
applicable securities laws, a person who is determined to be an audit committee

in the absence of such designation or identification.
