The Benefits and Risks of Leveraging

Preferred Income Strategies Fund, Inc. utilizes leveraging through borrowings or
issuance of short-term debt securities or shares of Preferred Stock. The concept
of leveraging is based on the premise that the cost of assets to be obtained
from leverage will be based on short-term interest or dividend rates, which
normally will be lower than the income earned by the Fund on its longer-term
portfolio investments. To the extent that the total assets of the Fund
(including the assets obtained from leverage) are invested in higher-yielding
portfolio investments, the Fund's Common Stock shareholders are the
beneficiaries of the incremental yield.

Leverage creates risks for holders of Common Stock including the likelihood of
greater net asset value and market price volatility. In addition, there is the
risk that fluctuations in interest rates on borrowings (or in the dividend rates
on any Preferred Stock, if the Fund were to issue Preferred Stock) may reduce
the Common Stock's yield and negatively impact its net asset value and market
price. If the income derived from securities purchased with assets received from
leverage exceeds the cost of leverage, the Fund's net income will be greater
than if leverage had not been used. Conversely, if the income from the
securities purchased is not sufficient to cover the cost of leverage, the Fund's
net income will be less than if leverage had not been used, and therefore the
amount available for distribution to Common Stock shareholders will be reduced.

A Letter From the President

Dear Shareholder

Index returns during the most recent six-month reporting period indicate that
fixed income markets continued to reward those investors who were willing to
accept greater risk. The high yield market, as measured by the Credit Suisse
First Boston High Yield Index, provided a return of +6.33% for the six months
ended April 30, 2004. By comparison, the Merrill Lynch U.S. Corporate Master
Index and the Merrill Lynch AAA U.S. Treasuries/Agencies 1 - 10 Year Index
returned +1.89% and +.67%, respectively, for the same period.

Throughout the period, short-term interest rates remained at historic lows and
kept the short end of the yield curve relatively flat, making it increasingly
difficult to find attractive income opportunities. As of April month-end, the
Federal Reserve Board maintained its accommodative policy stance, although a
better-than-expected employment report for the month of March prompted
speculation that an interest rate increase could come sooner than many had
expected. On April 2, 2004, the good news on the employment front -- previously
the one dim spot in an otherwise bright economic picture -- helped prompt the
yield on the 10-year Treasury note to spike nearly 25 basis points (.25%), from
3.91% to 4.15%. Market watchers continue to monitor economic data and Federal
Reserve Board language for indications of interest rate direction. If economic
growth maintains its recent pace and employment figures continue to improve,
many believe it is just a matter of time before interest rates move upward.

Equity markets, in the meantime, gleaned support from the improving economic
environment and provided attractive returns. For the six-month period ended
April 30, 2004, the Standard & Poor's 500 Index returned +6.27%. Significant
fiscal and monetary stimulus in 2003, including low interest rates and tax cuts,
has opened the door to consumer spending, capital spending, increases in exports
and long-awaited job growth. As expected, these developments have led the way to
improvements in corporate earnings -- a positive for stock markets.

The events and efforts of the past year leave us with a much stronger economy
today. Of course, markets will always fluctuate, and there are many
uncertainties -- not the least of which are geopolitical in nature -- which can
translate into negative market movements. Keeping this in mind, however, we
encourage you to revisit your portfolio and your asset allocation strategy to
ensure you are well positioned to take advantage of the opportunities that lie
ahead. Importantly, your financial advisor can help you develop a strategy most
suitable for your circumstances through all types of market and economic cycles.

We thank you for trusting Merrill Lynch Investment Managers with your investment
assets, and we look forward to serving you in the months and years ahead.

                                        Sincerely,


                                        /s/ Terry K. Glenn

A Discussion With Your Fund's Portfolio Managers

      The Fund recorded a positive return and outperformed its benchmark in a
period characterized by generally rising interest rates.

How did the Fund perform during the period in light of the existing market
conditions?

For the six-month period ended April 30, 2004, the Common Stock of Preferred
Income Strategies Fund, Inc. had net annualized yields of 9.50% and 10.39%,
based on a period-end per share net asset value of $23.91 and a per share market
price of $21.85, respectively, and $1.132 per share income dividends. For the
same period, the total investment return on the Fund's Common Stock was +2.53%,
based on a change in per share net asset value from $24.53 to $23.91, and
assuming reinvestment of $1.127 per share ordinary income dividends and $.094
per share capital gains distributions. For the same period, the unmanaged
Merrill Lynch Preferred Stock Fixed Rate Index returned -.03%.

For a description of the Fund's total investment return based on a change in the
per share market value of the Fund's Common Stock (as measured by the trading
price of the Fund's shares on the New York Stock Exchange), and assuming
reinvestment of dividends, please refer to the Financial Highlights section
included in this report. As a closed-end fund, the Fund's shares may trade in
the secondary market at a premium or discount to the Fund's net asset value. As
a result, total investment returns based on changes in the market value of the
Fund's Common Stock can vary significantly from total investment returns based
on changes in the Fund's net asset value.

Long-term interest rates declined somewhat early in the period, then rose
significantly in April. Throughout the period, we positioned the Fund with a
duration that was relatively short versus that of its benchmark, the Merrill
Lynch Preferred Stock Fixed Rate Index. This strategy proved successful as the
10-year U.S. Treasury note declined 1.36% between October 31, 2003 and April 30,
2004, while its yield increased from 4.30% to 4.50%. The unmanaged Merrill Lynch
U.S. Corporate Master Index and the Merrill Lynch U.S. Treasury/Agency Master
Index returned +1.89% and +.80%, respectively, for the same period.

Our use of hedge strategies also enhanced Fund performance. Hedges were used in
an effort to reduce the risk of loss associated with rising interest rates.
Among the hedges we implemented during the period were interest rate swaps, U.S.
Treasury futures and options on Treasury futures. During the period, we swapped
some fixed rate securities for variable rate issues. When interest rates
increase, the value of a variable rate security does not fall as much as that of
a fixed rate issue because its interest payments would adjust periodically to
keep pace with rising interest rates. Therefore, these swaps had a positive
effect on the Fund's return as interest rates moved higher late in the period.
Conversely, a fixed rate security would generally outperform a variable rate
obligation in a declining interest rate environment.

Our holdings in institutional preferred issues and underweights in $25 par
retail preferred and agency preferred securities also had a positive effect on
the Fund's comparative performance.

What is the Fund's investment objective?

The Fund's primary objective is to provide shareholders with current income. The
secondary objective is to seek capital appreciation. To these ends, we invest
primarily in a diversified portfolio of preferred securities, including
convertible preferred securities that may be converted into common stock or
other securities of the same or a different issuer. At least 80% of the Fund's
total assets are invested in securities rated in the investment grade rating
categories of the established bond rating services. Unrated securities held in
the portfolio would be those that we consider to be of comparable credit
quality.

What changes were made to the portfolio during the period?

As interest rates moved higher, we reduced the portfolio's duration -- which
already was shorter than that of its benchmark -- by two years. We trimmed the
Fund's exposure to


4       PREFERRED INCOME STRATEGIES FUND, INC.        APRIL 30, 2004


insurance, utilities and U.S. agencies, and added to its holdings in the banking
sector. The insurance sector had outperformed the overall preferred securities
market for some time, so we took profits on some of our holdings. We increased
the Fund's position in banking because we believed it was the highest quality
sector within the market.

Additionally, late in the period we reduced our holdings in preferred securities
that trade on the New York Stock Exchange and reinvested the proceeds in
preferred securities that trade in the over-the-counter market. Exchange traded
preferred securities are more vulnerable to extended rises in interest rates and
the reduction in exposure was a positive contribution to performance as interest
rates rose.

How would you characterize the Fund's position at the close of the period?

We have positioned the Fund with a short duration relative to its benchmark
index, as we believe long-term interest rates will continue to rise. The
portfolio also has extensive positive convexity. That is, as interest rates move
up, the portfolio's duration will fall, and vice versa. We believe the Fund's
duration will decrease further as interest rates continue to rise.

The portfolio is well diversified among issuers, and we intend to maintain the
diversification of our holdings across issuers and sectors. We also will
consider options to increase the Fund's yield and hedges to extend its duration
relative to the benchmark.

At April 30, 2004, the Fund was approximately 36% leveraged. (For a more
complete explanation of the benefits and risks of leveraging, see page 2 of this
report to shareholders.) Also at period-end, the portfolio carried an average
credit rating of Baa1 from Moody's, down slightly from an A3 rating at the
beginning of the period. Approximately 85.1% of the Fund's assets was invested
in securities rated Baa1 or higher at April 30, 2004.

Notes to Financial Statements

1. Significant Accounting Policies:

Preferred Income Strategies Fund, Inc. (the "Fund") is registered under the
Investment Company Act of 1940, as amended, as a diversified, closed-end
management investment company. The Fund's financial statements are prepared in
conformity with accounting principles generally accepted in the United States of
America, which may require the use of management accruals and estimates. Actual
results may differ from these estimates. These unaudited financial statements
reflect all adjustments, which are, in the opinion of management, necessary to a
fair statement of the results for the interim period presented. All such
adjustments are of a normal, recurring nature. The Fund's Common Stock is listed
on the New York Stock Exchange ("NYSE") under the symbol PSY. The following is a
summary of significant accounting policies followed by the Fund.

(a) Valuation of investments -- Equity securities that are held by the Fund that
are traded on stock exchanges or the Nasdaq National Market are valued at the
last sale price or official close price on the exchange, as of the close of
business on the day the securities are being valued or, lacking any sales, at
the last available bid price for long positions, and at the last available ask
price for short positions. In cases where equity securities are traded on more
than one exchange, the securities are valued on the exchange designated as the
primary market by or under the authority of the Board of Directors of the Fund.
Long positions traded in the over-the-counter ("OTC") market, Nasdaq Small Cap
or Bulletin Board are valued at the last available bid price or yield equivalent
obtained from one or more dealers or pricing services approved by the Board of
Directors of the Fund. Short positions traded in the OTC market are valued at
the last available ask price. Portfolio securities that are traded both in the
OTC market and on a stock exchange are valued according to the broadest and most
representative market.

Options written are valued at the last sale price in the case of exchange-traded
options or, in the case of options traded in the OTC market, the last ask price.
Options purchased are valued at their last sale price in the case of
exchange-traded options or, in the case of options traded in the OTC market, the
last bid price. Swap agreements are valued daily based upon quotations from
market makers. Financial futures contracts and options thereon, which are traded
on exchanges, are valued at their last sale price as of the close of such
exchanges. Obligations with remaining maturities of 60 days or less are valued
at amortized cost unless the Investment Adviser believes that this method no
longer produces fair valuations.

Repurchase agreements are valued at cost plus accrued interest. The Fund employs
pricing services to provide certain securities prices for the Fund. Securities
and assets for which market quotations are not readily available are valued at
fair value as determined in good faith by or under the direction of the Board of
Directors of the Fund, including valuations furnished by the pricing services
retained by the Fund, which may use a matrix system for valuations. The
procedures of a pricing service and its valuations are reviewed by the officers
of the Fund under the general supervision of the Fund's Board of Directors. Such
valuations and procedures will be reviewed periodically by the Board of
Directors of the Fund.

Generally, trading in foreign securities, as well as U.S. government securities
and money market instruments, is substantially completed each day at various
times prior to the close of business on the NYSE. The values of such securities
used in computing the net asset value of the Fund's shares are determined as of
such times. Foreign currency exchange rates also are generally determined prior
to the close of business on the NYSE. Occasionally, events affecting the values
of such securities and such exchange rates may occur between the times at which
they are determined and the close of business on the NYSE that may not be
reflected in the computation of the Fund's net asset value. If events (for
example, a company announcement, market volatility or a natural disaster) occur
during such periods that are expected to materially affect the value of such
securities, those securities may be valued at their fair value as determined in
good faith by the Fund's Board of Directors or by the Investment Adviser using a
pricing service and/or procedures approved by the Fund's Board of Directors.

(b) Derivative financial instruments -- The Fund may engage in various portfolio
investment strategies both to increase the return of the Fund and to hedge, or
protect, its exposure to interest rate movements and movements in the securities
markets. Losses may arise due to changes in the value of the contract or if the
counterparty does not perform under the contract.

o     Options -- The Fund may write and purchase call and put options. When the
      Fund writes an option, an amount equal to the premium received by the Fund
      is reflected as an asset and an equivalent liability. The amount of the
      liability is subsequently marked to market to reflect the


        PREFERRED INCOME STRATEGIES FUND, INC.        APRIL 30, 2004          17

Notes to Financial Statements (continued)

      current market value of the option written. When a security is purchased
      or sold through an exercise of an option, the related premium paid (or
      received) is added to (or deducted from) the basis of the security
      acquired or deducted from (or added to) the proceeds of the security sold.
      When an option expires (or the Fund enters into a closing transaction),
      the Fund realizes a gain or loss on the option to the extent of the
      premiums received or paid (or gain or loss to the extent the cost of the
      closing transaction exceeds the premium paid or received).

      Written and purchased options are non-income producing investments.

o     Financial futures contracts -- The Fund may purchase or sell financial
      futures contracts and options on such futures contracts. Futures contracts
      are contracts for delayed delivery of securities at a specific future date
      and at a specific price or yield. Upon entering into a contract, the Fund
      deposits and maintains as collateral such initial margin as required by
      the exchange on which the transaction is effected. 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 value of the contract. Such
      receipts or payments are known as variation margin and are recorded by the
      Fund as unrealized gains or losses. When the contract is closed, the Fund
      records a realized 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.

o     Swaps -- The Fund may enter into swap agreements, which are
      over-the-counter contracts in which the Fund and a counterparty agree to
      make periodic net payments on a specified notional amount. The net
      payments can be made for a set period of time or may be triggered by a
      predetermined credit event. The net periodic payments may be based on a
      fixed or variable interest rate; the change in market value of a specified
      security, basket of securities, or index; or the return generated by a
      security.

(c) Income taxes -- 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.
Therefore, no Federal income tax provision is required.

(d) Security transactions and investment income -- Security transactions are
recorded on the dates the transactions are entered into (the trade dates).
Realized gains and losses on security transactions are determined on the
identified cost basis. Dividend income is recorded on the ex-dividend dates.
Interest income is recognized on the accrual basis. The Fund amortizes all
premiums and discounts on debt securities.

(e) Offering expenses -- Direct expenses relating to the public offering of the
Fund's Common Stock were charged to capital at the time of issuance of the
shares.

(f) Dividends and distributions -- Dividends from net investment income are
declared and paid monthly. Distributions of capital gains are recorded on the
ex-dividend dates.

2. Investment Advisory Agreement and Transactions with Affiliates:

The Fund has entered into an Investment Advisory Agreement with Fund Asset
Management, L.P. ("FAM"). The general partner of FAM is Princeton Services, Inc.
("PSI"), an indirect, wholly-owned subsidiary of Merrill Lynch & Co., Inc. ("ML
& Co."), which is the limited partner.

FAM is responsible for the management of the Fund's portfolio and provides the
necessary personnel, facilities, equipment and certain other services necessary
to the operations of the Fund. For such services, the Fund pays a monthly fee at
an annual rate of .60% of the Fund's average weekly net assets including
proceeds from the issuance of Preferred Stock, plus the proceeds of any
outstanding borrowings used for leverage.

For the six months ended April 30, 2004, the Fund reimbursed FAM $31,150 for
certain accounting services.

Certain officers and/or directors of the Fund are officers and/or directors of
FAM, PSI, and/or ML & Co.

4. Stock Transactions:

The Fund is authorized to issue 200,000,000 shares of stock, including Preferred
Stock, par value $.10 per share, all of which were initially classified as
Common Stock. The Board of Directors is authorized, however, to reclassify any
unissued shares of stock without approval of holders of Common Stock.

Common Stock

Shares issued and outstanding during the six months ended April 30, 2004
remained constant and during the period March 28, 2003 to October 31, 2003
increased by 40,550,000 from shares sold and 38,881 from reinvestments.

Preferred Stock

Auction Market Preferred Stock are redeemable shares of Preferred Stock of the
Fund, with a par value of $.10 per share and liquidation preference of $25,000
per share, plus accrued and unpaid dividends, that entitle their holders to
receive cash dividends at an annual rate that may vary for the successive
dividend periods. The yields in effect at April 30, 2004 were as follows: Series
M7, 1.08%; Series T7, 1.08%; Series W7, 1.08%; Series TH7, 1.10%; Series F7,
1.09%; Series W28, 1.08% and Series TH28, 1.07%.

Shares issued and outstanding during the six months ended April 30, 2004
remained constant and during the period May 16, 2003 to October 31, 2003
increased by 22,000 from issuance of Preferred Stock.

The Fund pays commissions to certain broker-dealers at the end of each auction
at an annual rate ranging from .25% to .375%, calculated on the proceeds of each
auction. For the six months ended April 30, 2004, Merrill Lynch, Pierce, Fenner
& Smith Incorporated, an affiliate of FAM, earned $286,886 as commissions.

5. Subsequent Event:

Preferred Income Strategies Fund, Inc. seeks to provide shareholders with
current income. The secondary objective of the Fund is to seek to provide
shareholders with capital appreciation. The Fund seeks to achieve its objectives
by investing primarily in a portfolio of preferred securities, including
convertible preferred securities that may be converted into common stock or
other securities of the same or a different issuer.

This report, including the financial information herein, is transmitted to
shareholders of Preferred Income Strategies Fund, Inc. for their information. It
is not a prospectus. The Fund leverages its Common Stock to provide Common Stock
shareholders with a potentially higher rate of return. Leverage creates risk for
Common Stock shareholders, including the likelihood of greater volatility of net
asset value and market price of Common Stock shares, and the risk that
fluctuations in short-term interest rates may reduce the Common Stock's yield.
Past performance results shown in this report should not be considered a
representation of future performance. Statements and other information herein
are as dated and are subject to change.
