                                               Overview (unaudited)

LETTER TO STOCKHOLDERS

PERFORMANCE

For the six months ended April 30, 2004, The Turkish Investment Fund, Inc. (the
"Fund") had a total return, based on net asset value per share, of 26.98%
compared to 13.98% for the U.S. dollar adjusted Morgan Stanley Capital
International (MSCI) Turkey Index (the "Index"). On April 30, 2004, the closing
price of the Fund's shares on the New York Stock Exchange was $10.93,
representing a 20.9% premium to the Fund's net asset value per share.

FACTORS AFFECTING PERFORMANCE

    - During the six months ending April 30, 2004, Turkish equities gained
      13.98% as the market performed well, given the improving economic and
      political environment.

    - Turkish equities, however, did not escape the period in review without
      renewed volatility. After a period of relative tranquility, volatility in
      Turkey spiked in April. Turkish equities posted their weakest performance
      since March 2003, declining 16.9% in April after gaining 125.3% in 2003
      and another 13.1% in the first three months of 2004.

    - The difficulties in April were based primarily on external factors though
      internal reasons exist as well. Externally, fears of future U.S. interest
      rate hikes and a China slowdown hurt all equity markets, while domestic
      sentiment weakened given the disappointment over the failed Cyprus
      reunification plan.

    - Investor confidence in the economic and political policies of the popular
      Ak political party, the continuing decline in inflation expectations, and
      the strengthening Turkish Lira have all helped to reduce real interest
      rates to their lowest level in three years.

    - The falling interest rate environment has helped to alleviate the domestic
      debt burden on the economy and lowering perceptions of risk for Turkish
      real assets, while fueling a resumption in credit growth, investment, and
      consumption.

    - The consensus expectation for Turkey's gross domestic product growth is
      above 5.5% for 2004, driven by declining real interest rates as well as a
      pick-up in private investment and consumption. The country may achieve
      single digit inflation for the first time in more than 30 years.

    - In terms of relative performance, both sector allocation and stock
      selection were positive contributors. Stock selection within financials,
      materials, and consumer discretionary sectors were particularly strong. On
      a sector allocation basis, our overweight position in consumer
      discretionary, telecommunication services, and industrials coupled with
      underweight positions in energy and financials contributed positively to
      relative performance. Stock selection within industrials and
      telecommunication services detracted slightly from relative returns.

MANAGEMENT STRATEGIES

    - The Fund continues to integrate top-down sector allocation and bottom-up
      stock selection with a growth bias utilizing a rigorous and fundamental
      research approach that considers dynamics, valuation, and sentiment.

    - Despite the strong performance of the Turkish equity market in 2003,
      earnings growth continues to outpace the rise in asset prices. We continue
      to focus on various sectors that will benefit from improving domestic
      demand, including financials, consumer discretionary, industrials, and
      telecommunications.


Sincerely,

/s/ Ronald E. Robison

NOTES TO FINANCIAL STATEMENTS

The Turkish Investment Fund, Inc. (the "Fund") was incorporated in Maryland on
September 27, 1988 and is registered as a non-diversified, closed-end management
investment company under the Investment Company Act of 1940, as amended. The
Fund's investment objective is long-term capital appreciation through
investments primarily in equity securities of Turkish corporations.

A.  ACCOUNTING POLICIES: The following significant accounting policies are in
conformity with accounting principles generally accepted in the United States.
Such policies are consistently followed by the Fund in the preparation of its
financial statements. Accounting principles generally accepted in the United
States may require management to make estimates and assumptions that affect the
reported amounts and disclosures in the financial statements. Actual results may
differ from those estimates.

1.  SECURITY VALUATION: Equity securities listed on a U.S. exchange are valued
    at the latest quoted sales price on the valuation date. Equity securities
    listed or traded on NASDAQ, for which market quotations are available, are
    valued at the NASDAQ Official Closing Price. Securities listed on a foreign
    exchange are valued at their closing price. Unlisted securities and listed
    securities not traded on the valuation date for which market quotations are
    readily available are valued at the mean between the current bid and asked
    prices obtained from reputable brokers. Debt securities purchased with
    remaining maturities of 60 days or less are valued at amortized cost, if it
    approximates value.

    All other securities and investments for which market values are not readily
    available, including restricted securities, and those securities for which
    it is inappropriate to determine prices in accordance with the
    aforementioned procedures, are valued at fair value as determined in good
    faith under procedures adopted by the Board of Directors, although the
    actual calculations may be done by others. Factors considered in making this
    determination may include, but are not limited to, information obtained by
    contacting the issuer, analysts, or the appropriate stock exchange (for
    exchange-traded securities), analysis of the issuer's financial statements
    or other available documents and, if necessary, available information
    concerning other securities in similar circumstances.

    Most foreign markets close before the New York Stock Exchange (NYSE).
    Occasionally, developments that could affect 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 these
    developments are expected to materially affect the value of the securities,
    the valuations may be adjusted to reflect the estimated fair value as of the
    close of the NYSE, as determined in good faith under procedures established
    by the Board of Directors.

2.  REPURCHASE AGREEMENTS: The Fund may enter into repurchase agreements under
    which the Fund lends excess cash and takes possession of securities with an
    agreement that the counterparty will repurchase such securities. In
    connection with transactions in repurchase agreements, a bank as custodian
    for the Fund takes possession of the underlying securities (collateral),
    with a market value at least equal to the amount of the repurchase
    transaction, including principal and accrued interest. To the extent that
    any repurchase transaction exceeds one business day, the value of the
    collateral is marked-to-market on a daily basis to determine the adequacy of
    the collateral. In the event of default on the obligation to repurchase, the
    Fund has the right to liquidate the collateral and apply the proceeds in
    satisfaction of the obligation. In the event of default or bankruptcy by the
    counterparty to the agreement, realization and/or retention of the
    collateral or proceeds may be subject to legal proceedings.

    The Fund, along with other affiliated investment companies, may utilize a
    joint trading account for the purpose of entering into one or more
    repurchase agreements.

3.  FOREIGN CURRENCY TRANSLATION: The books and records of the Fund are
    maintained in U.S. dollars. Amounts denominated in Turkish lira are
    translated into U.S. dollars at the mean of the bid and asked prices of such
    currency against U.S. dollars last quoted by a major bank as follows:

    -- investments, other assets and liabilities at the prevailing rate of
    exchange on the valuation date;

    --investment transactions and investment income at the prevailing rate of
    exchange on the dates of such transactions.

    Although the net assets of the Fund are presented at the foreign exchange
    rate and market values at the close of the period, the Fund does not isolate
    that portion of the results of operations arising as a result of changes in
    the foreign exchange rate from the fluctuations arising from changes in the
    market prices of the securities held at period end. Similarly, the Fund does
    not isolate the effect of changes in the foreign exchange rate from the
    fluctuations arising from

NOTES TO FINANCIAL STATEMENTS (CONT'D)

    changes in the market prices of securities sold during the period.
    Accordingly, realized and unrealized foreign currency gains (losses) due to
    securities transactions are included in the reported net realized and
    unrealized gains (losses) on investment transactions and balances.

    Net realized gains (losses) on foreign currency transactions represent net
    foreign exchange gains (losses) from sales and maturities of foreign
    currency exchange contracts, disposition of foreign currency, currency gains
    or losses realized between the trade and settlement dates on securities
    transactions, and the difference between the amount of investment income and
    foreign withholding taxes recorded on the Fund's books, and the U.S. dollar
    equivalent amounts actually received or paid. Net unrealized currency gains
    (losses) from valuing foreign currency denominated assets and liabilities at
    period end exchange rates are reflected as a component of unrealized
    appreciation (depreciation) on investments and foreign currency translations
    in the Statement of Net Assets. The change in net unrealized currency gains
    (losses) on foreign currency translations for the period is reflected in the
    Statement of Operations.

    A significant portion of the Fund's net assets consists of equity securities
    denominated in Turkish lira. Changes in currency exchange rates will affect
    the value of and investment income from securities. Turkish securities are
    often subject to greater price volatility, limited capitalization and
    liquidity, and higher rates of inflation than securities of companies based
    in the United States. In addition, Turkish securities may be subject to
    substantial governmental involvement in the economy and greater social,
    economic and political uncertainty.

The Fund may use derivatives to achieve its investment objectives. The Fund may
engage in transactions in futures contracts on foreign currencies, stock
indices, as well as in options, swaps and structured notes. Consistent with the
Fund's investment objectives and policies, the Fund may use derivatives for
non-hedging as well as hedging purposes.

Following is a description of derivative instruments that the Fund has utilized
and their associated risks:

4.  FOREIGN CURRENCY EXCHANGE CONTRACTS: The Fund may enter into foreign
    currency exchange contracts generally to attempt to protect securities and
    related receivables and payables against changes in future foreign exchange
    rates and, in certain situations, to gain exposure to a foreign currency. A
    foreign currency exchange contract is an agreement between two parties to
    buy or sell currency at a set price on a future date. The market value of
    the contract will fluctuate with changes in currency exchange rates. The
    contract is marked-to-market daily and the change in market value is
    recorded by the Fund as unrealized gain or loss. The Fund records realized
    gains or losses when the contract is closed 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. Risk may arise upon entering into these contracts from
    the potential inability of counterparties to meet the terms of their
    contracts and is generally limited to the amount of unrealized gain on the
    contracts, if any, at the date of default. Risks may also arise from
    unanticipated movements in the value of a foreign currency relative to the
    U.S. dollar.

5.  OTHER: Security transactions are accounted for on the date the securities
    are purchased or sold. Realized gains and losses on the sale of investment
    securities are determined on the specific identified cost basis. Interest
    income is recognized on the accrual basis. Dividend income is recorded on
    the ex-dividend date (except certain dividends which may be recorded as soon
    as the Fund is informed of such dividends) net of applicable withholding
    taxes.

B.  ADVISERS: Morgan Stanley Investment Management Inc. and Morgan Stanley
Investment Management Limited (the "Advisers") provide investment advisory
services to the Fund under the terms of an Investment Advisory Agreement (the
"Agreement"). Under the Agreement, advisory fees are computed weekly and payable
monthly at an annual rate of 0.95% of the Fund's first $50 million of average
weekly net assets, 0.75% of the next $50 million of average weekly net assets
and 0.55% of average weekly net assets in excess of $100 million.

C.  ADMINISTRATOR: JPMorgan Chase Bank, through its corporate affiliate J.P.
Morgan Investor Services Co. (the "Administrator"), provides administrative
services to the Fund under an Administration Agreement. The Administrator is
paid a fee computed weekly and payable monthly at an annual rate of 0.02435% of

and distributions to stockholders are recorded on the ex-dividend date.

The Fund may be subject to taxes imposed by countries in which it invests. Such
taxes are generally based on income and/or capital gains earned or repatriated.
Taxes are accrued and applied to net investment income, net realized gains and
net unrealized appreciation as such income and/or gains are earned.

The tax character of distributions paid may differ from the character of
distributions shown on the Statements of Changes in Net Assets due to short-term
capital gains being treated as ordinary income for tax purposes. The tax
character of distributions paid during 2003 and 2002 was as follows:

<Table>
<Caption>
    2003 DISTRIBUTIONS     2002 DISTRIBUTIONS
        PAID FROM:             PAID FROM:
          (000)                  (000)
- -----------------------    -------------------
              LONG-TERM              LONG-TERM
   ORDINARY     CAPITAL    ORDINARY    CAPITAL
     INCOME       GAIN       INCOME      GAIN

      $  --        $ --       $ 26        $ --
</Table>

The amount and character of income and capital gain distributions to be paid by
the Fund are determined in accordance with Federal income tax regulations, which
may differ from accounting principles generally accepted in the United States.
The book/ tax differences are considered either temporary or permanent in
nature.

Temporary differences are attributable to differing book and tax treatments for
the timing of the recognition of gains and losses on certain investment
transactions and the timing of the deductibility of certain expenses.

Permanent book and tax basis differences may result in reclassifications among
undistributed (distributions in excess of) net investment income (or accumulated
net investment loss), accumulated net realized gain (loss) and paid-in capital.

At October 31, 2003, the components of distributable earnings on a tax basis
were as follows:

<Table>

       UNDISTRIBUTED              UNDISTRIBUTED

</Table>

At April 30, 2004, the U.S. Federal income tax cost basis of investments
(excluding foreign currency if applicable) was $41,853,000 and, accordingly, net
unrealized appreciation for U.S. Federal income tax purposes was $7,003,000, of
which $7,900,000 related to appreciated securities and $897,000 related to
depreciated securities.

At October 31, 2003, the Fund had a capital loss carryforward for U.S. Federal
income tax purposes of approximately $34,359,000 available to offset future
capital gains of which $9,207,000 will expire on October 31, 2009 and
$25,152,000 will expire on October 31, 2010.

To the extent that capital loss carryovers are used to offset any future capital
gains realized during the carryover period as provided by U.S. Federal income
tax regulations, no capital gains tax liability will be incurred by a portfolio
for gains realized and not distributed. To the extent that capital gains are
offset, such gains will not be distributed to the stockholders.

F.  CONTRACTUAL OBLIGATIONS: The Fund enters into contracts that contain a
    variety of indemnifications. The Fund's maximum exposure under these
    arrangements is unknown. However, the Fund has not had prior claims or
    losses pursuant to these contracts and expects the risk of loss to be
    remote.

G.  OTHER: During the six months ended April 30, 2004, the Fund made purchases
    and sales totaling $35,699,000 and $38,931,000, respectively, of investment
    securities other than long-term U.S. Government securities and short-term
    investments. There were no purchases or sales of long-term U.S. Government
    securities.

During the six months ended April 30, 2004, the Fund incurred $2,000 of
brokerage commissions with Morgan Stanley & Co., Incorporated, an affiliate of
the Advisers.

On September 15, 1998, the Fund commenced a share repurchase program for
purposes of enhancing stockholder value and reducing the discount at which the
Fund's shares trade from their net asset value. For the six months ended April
30, 2004, the Fund did not repurchase shares. From the inception of the program
through April 30, 2004, the Fund has repurchased 1,427,394 of its shares at an
average discount of 17.25% from net asset value per share. The Fund expects to
continue to repurchase its outstanding shares at such time and in such amounts
as it believes will further the accomplishment of the foregoing objectives,
subject to review by the Board of Directors.

DIVIDEND REINVESTMENT AND CASH PURCHASE PLAN

    Pursuant to the Dividend Reinvestment and Cash Purchase Plan (the "Plan"),
each stockholder will be deemed to have elected, unless American Stock Transfer
& Trust Company (the "Plan Agent") is otherwise instructed by the stockholder in
writing, to have all distributions automatically reinvested in Fund shares.
Participants in the Plan have the option of making additional voluntary cash
payments to the Plan Agent, annually, in any amount from $100 to $3,000, for
investment in Fund shares.

    Dividend and capital gain distributions will be reinvested on the
reinvestment date in full and fractional shares. If the market price per share
equals or exceeds net asset value per share on the reinvestment date, the Fund
will issue shares to participants at net asset value. If net asset value is less
than 95% of the market price on the reinvestment date, shares will be issued at
95% of the market price. If net asset value exceeds the market price on the
reinvestment date, participants will receive shares valued at market price. The
Fund may purchase shares of its Common Stock in the open market in connection
with dividend reinvestment requirements at the discretion of the Board of
Directors. Should the Fund declare a dividend or capital gain distribution
payable only in cash, the Plan Agent will purchase Fund shares for participants
in the open market as agent for the participants.

    The Plan Agent's fees for the reinvestment of dividends and distributions
will be paid by the Fund. However, each participant's account will be charged a
pro rata share of brokerage commissions incurred on any open market purchases
effected on such participant's behalf. A participant will also pay brokerage
commissions incurred on purchases made by voluntary cash payments. Although
stockholders in the Plan may receive no cash distributions, participation in the
Plan will not relieve participants of any income tax which may be payable on
such dividends or distributions.

    In the case of stockholders, such as banks, brokers or nominees, that hold
shares for others who are the beneficial owners, the Plan Agent will administer
the Plan on the basis of the number of shares certified from time to time by the
stockholder as representing the total amount registered in the stockholder's
name and held for the account of beneficial owners who are participating in the
Plan.

    Stockholders who do not wish to have distributions automatically reinvested
should notify the Plan Agent in writing. There is no penalty for
non-participation or withdrawal from the Plan, and stockholders who have
previously withdrawn from the Plan may rejoin at any time. Requests for
additional information or any correspondence concerning the Plan should be
directed to the Plan Agent at:
