        Market Leader Trust performed during the semiannual period. We will
        provide an overview of the market conditions, and discuss some of the
        factors that affected performance during the reporting period. In
        addition, this report includes the Fund's financial statements and a
        list of Fund investments.



        This material must be preceded or accompanied by a prospectus for the
        fund being offered. Market forecasts provided in this report may not
        necessarily come to pass. There is no assurance that the Fund will
        achieve its investment objective. The Fund is subject to market risk,
        which is the possibility that market values of securities owned by the
        Fund will decline and, therefore, the value of the Fund's shares may be
        less than what you paid for them. Accordingly, you can lose money
        investing in this Fund.

Past performance is no guarantee of future results and current performance may
be lower or higher than the figures shown. For more up-to-date information,
including month-end performance figures, please visit morganstanley.com or speak
with your financial Advisor. Investment returns and principal value will
fluctuate and fund shares, when redeemed, may be more or less than their
original cost.

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 not reflect the deduction of any applicable sales
charges. Such costs would lower performance. See Performance Summary for
standardized performance information.


MARKET CONDITIONS

The six-month period ended February 29, 2004 demonstrated trends that built on
the economic resurgence of early 2003 towards economic growth, solid earnings
reports and positive equity performance. U.S. Gross Domestic Product grew by
more than eight percent in the third quarter of 2003 and four percent in the
fourth, while corporate earnings forecasts grew increasingly positive. Large-cap
companies lagged smaller ones as investors sought cheap companies with
turnaround potential. This preference led to higher-beta, more aggressive stocks
leading the rally. Information technology, energy and small-cap health care
stocks returned the strongest results. Consumer discretionary and utilities
lagged their sector peers due to their more-stable nature, though all returned
positive results. Precious metals stocks strengthened as a hedge against
currency instability as the U.S. dollar weakened.

Investor sentiment changed as 2003 came to a close. Investors reduced risk
exposure on fears of an interest rate hike by the Federal Reserve by shifting
assets to defensive sectors and others that had been lagging. For example,
telecommunications had lagged the 2003 rally but was a sector leader for the
month of January 2004 amid speculation of merger activity. The U.S. dollar also
gained during January. The dollar's appreciation had the effect of reversing
some of the previous year's gains in the precious metals sector.


PERFORMANCE ANALYSIS

Morgan Stanley Market Leader Trust underperformed the S&P 500 Index and
underperformed the Lipper Large-Cap Core Funds Index for the six-month period
ended February 29, 2004. Relative to the S&P 500 Index, the Fund's
underperformance was attributable to both sector allocation and stock selection
decisions. The two greatest detractors were stock selection in consumer
discretionary stocks and an overweighted position in the information technology
sector. The Fund's consumer discretionary holdings were hurt by underperforming
media stocks such as Liberty Media and Viacom, which we continue to believe are
poised for strong performance as the economy and advertising recovers,
particularly since 2004 has both a Presidential election and the Olympics. Our
underweighted position relative to the S&P 500 Index in Altria as well as our
investments in discount retailers Dollar Tree and Kohl's, which suffered from
heavy competition, also hurt performance. After a strong run for most of 2003,
technology stocks have more recently underperformed the overall market. As a
result, the Fund's above-market exposure to information technology stocks was
also a drag on






performance. Another relative detractor was the Fund's utilities underweight.
Utilities rallied in the closing months of the period amid ongoing high energy
prices.

Several of the Fund's positions contributed to relative performance, however.
Health care was our strongest performing sector, led by Pfizer, which gave
strong earnings forecasts. The Fund's stock selection in basic materials also
aided performance, as copper mining company Phelps-Dodge and aluminum mining
company Alcoa rallied on increased manufacturing activity and high demand for
materials from China.

INVESTMENT STRATEGY

The Fund will normally invest at least 65% of its assets in common stocks and
other equity securities of companies that the Fund's "Investment Manager,"
Morgan Stanley Investment Advisors Inc., believes are established market leaders
in growing industries and are positioned to generate strong earnings and free
cash flow growth. The Investment Manager considers companies to be "market
leaders" if they are nationally-known and have established a strong reputation
for quality management, products and services in the United States and/or
globally. These companies generally will have market capitalizations in excess
of $1 billion and will be listed in the United States on a national stock
exchange. The Fund's other equity investments in market leaders may include
preferred stocks, debt or preferred stocks convertible into common stocks and
depositary receipts. Up to 10% of the Fund's net assets may be invested in
foreign securities that are not listed in the United States on a national
securities exchange. In addition, the Fund may invest up to 20% of its net
assets in lower rated convertible securities (commonly known as "junk bonds").

MORGAN STANLEY MARKET LEADER TRUST
NOTES TO FINANCIAL STATEMENTS | February 29, 2004 (unaudited)

1. ORGANIZATION AND ACCOUNTING POLICIES

Morgan Stanley Market Leader Trust (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
long-term growth of capital. The Fund seeks to achieve its investment objective
by investing at least 65% of its assets in equity securities issued by companies
that are established leaders in their respective fields in growing industries in
domestic and foreign markets. The Fund was organized as a Massachusetts business
trust on November 4, 1996 and commenced operations on April 28, 1997. On July
28, 1997, the Fund converted to a multiple class share structure.

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 Stock Exchange ("NYSE") 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 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 . Occasionally, developments affecting the
closing prices of securities and other assets may occur between the times at
which valuations of such securities are determined (that is, close of the
foreign market on which the securities trade) and the close of business on the
NYSE. If developments occur during such periods that are expected to materially
affect the value of such securities, such valuations may be adjusted to reflect
the estimated fair value of such securities as of the close of the NYSE, as
determined in good faith by the Fund's Trustees or by the Investment Manager
using a pricing service and/or procedures approved by the Trustees of the Fund;
(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







MORGAN STANLEY MARKET LEADER TRUST
NOTES TO FINANCIAL STATEMENTS | February 29, 2004 (unaudited) continued

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 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. 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
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.

F. 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

NOTES TO FINANCIAL STATEMENTS | February 29, 2004 (unaudited) continued

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.

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 the Investment
Manager a management fee, accrued daily and payable monthly, by applying the
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 $1 billion
and 0.725% to the portion of daily net assets in excess of $1 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
$10,064,390 at February 29, 2004.

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.








MORGAN STANLEY MARKET LEADER TRUST
NOTES TO FINANCIAL STATEMENTS | February 29, 2004 (unaudited) continued

For the year ended February 29, 2004, the distribution fee was accrued for Class
A shares and Class C shares at the annual rate of 0.23% and 0.90%, respectively.

The Distributor has informed the Fund that for the six months ended February 29,
2004, it received contingent deferred sales charges from certain redemptions of
the Fund's Class B shares and Class C shares of $253,443 and $1,172,
respectively and received $10,872 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 six months ended February 29, 2004 aggregated
$394,651,978 and $433,925,731, respectively. Included in the aforementioned
transactions are purchases and sales of $13,513,434 and $2,228,636,
respectively, for portfolio transactions with other Morgan Stanley funds,
including a realized gain of $502,099.

For the six months ended February 29, 2004, the Fund incurred brokerage
commissions of $15,371 with Morgan Stanley & Co., Inc., an affiliate of the
Investment Manager and Distributor, for portfolio transactions executed on
behalf of the Fund.

Morgan Stanley Trust, an affiliate of the Investment Manager and Distributor, is
the Fund's transfer agent. At February 29, 2004, the Fund had transfer agent
fees and expenses payable of approximately $224,300.


5. SHARES OF BENEFICIAL INTEREST

Transactions in shares of beneficial interest were as follows:

6. 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 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 August 31, 2003, the Fund had a net capital loss carryover of $167,503,738
of which $1,989,440 will expire on August 31, 2009, $50,201,996 will expire on
August 31, 2010 and $115,312,302 will expire on August 31, 2011 to offset future
capital gains to the extent provided by regulations.

At August 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 of the Fund's next taxable) and capital loss deferrals on wash sales.


7. 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 amounts 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 arise upon entering into these
contracts from the potential inability of the counterparties to meet the terms
of their contracts.


8. LEGAL MATTERS

The Investment Manager, certain affiliates of the Investment Manager, certain
officers of such affiliates and certain investment companies advised by the
Investment Manager or its affiliates, including the Fund, are named as
defendants in a number of similar class action complaints which were recently
consolidated. This consolidated action also names as defendants certain
individual Trustees and Directors of the Morgan Stanley funds. The consolidated
amended complaint generally alleges that defendants, including the Fund,
violated their statutory disclosure obligations and fiduciary duties by failing
properly to disclose (i) that the Investment Manager and certain affiliates of
the Investment Manager allegedly offered economic incentives






MORGAN STANLEY MARKET LEADER TRUST
NOTES TO FINANCIAL STATEMENTS | February 29,2004 (unaudited) continued

to brokers and others to recommend the funds advised by the Investment Manager
or its affiliates to investors rather than funds managed by other companies, and
(ii) that the funds advised by the Investment Manager or its affiliates,
including the Fund, allegedly paid excessive commissions to brokers in return
for their efforts to recommend these funds to investors. The complaint seeks,
among other things, unspecified compensatory damages, recessionary damages, fees
and costs. The defendants intend to move to dismiss the action and otherwise
vigorously to defend it. While the Fund believes that it has meritorious
defenses, the ultimate outcome of this matter is not presently determinable at
this early stage of the litigation, and no provision has been made in the Fund's
financial statements for the effect, if any, of this matter.


9. SUBSEQUENT EVENT - FUND MERGER

("Growth") based on the respective valuations as of the close of business on
