Manager Overview

MARKET OVERVIEW

The six-month period ended February 29, 2004 was a strong one for most equity
markets. After uncertainty leading up to the war in Iraq in February and March
2003, stock markets embarked on a sustained rise that remained intact through
the beginning of 2004.

The economy also showed general signs of improvement. The problems associated
with the collapse of the late 1990s "bubble" -- namely, too much debt and too
much capacity in certain industries -- appear to have been overcome. U.S.
businesses began to increase their level of capital spending after a severe
contraction in 2001 and 2002. So far, the acceleration in growth has not ignited
any pickup in inflation. New federal tax legislation also provided a significant
near-term tax cut for customers, businesses and investors while key interest
rates continued to hover near record lows. These factors, among others,
contributed to a very broad based stock market rally.

Performance Review

Within this environment, the fund performed as follows. For the six months ended
February 29, 2004, the fund returned 13.58%. The fund underperformed its
unmanaged benchmark, the S&P 500 Index, /i/ which returned 14.59% for the same
period. The fund also underperformed its Lipper multi-cap value funds category
average, which returned 16.65% for the same period. /1/ The fund's cash position
during a time in which the S&P 500 Index advanced, its underweighting of the
telecommunications services sector, and lack of exposure to the utilities
industry contributed to its underperformance relative to the S&P 500 Index.


                              PERFORMANCE SNAPSHOT
                             AS OF FEBRUARY 29, 2004

guarantee of future results and current performance may be higher or lower than
the performance shown above. Principal value and investment returns will
fluctuate and investors' shares, when redeemed, may be worth more or less than

distributions at net asset value and the deduction of all fund expenses. Returns
have not been adjusted to include deduction of taxes that a shareholder would
pay on fund distributions.

All index performance reflects no deduction for fees, expenses or taxes. The S&P
500 Index is a market capitalization-weighted index of 500 widely held common
stocks. Please note that an investor cannot invest directly in an index.


1 Lipper, Inc. is a major independent mutual-fund tracking organization. Returns

Information About Your Fund

In recent months several issues in the mutual fund industry have come under the
scrutiny of federal and state regulators. The fund's Adviser and some of its
affiliates have received requests for information from various government
regulators regarding market timing, late trading, fees and other mutual fund
issues in connection with various investigations. The regulators appear to be
examining, among other things, the fund's response to market timing and
shareholder exchange activity, including compliance with prospectus disclosure
related to these subjects. The fund has been informed that the Adviser and its
affiliates are responding to those information requests, but are not in a
position to predict the outcome of these requests and investigations.

As always, thank you for your confidence in our stewardship of your assets. We
look forward to helping you continue to meet your financial goals.

Sincerely,

/s/ George J. Williamson

The information provided is not intended to be a forecast of future events, a
guarantee of future results or investment advice. Views expressed may differ
from those of the firm as a whole.

Portfolio holdings and breakdowns are as of February 29, 2004 and are subject to
change. Please refer to pages 4 through 7 for a list and percentage breakdown of
the fund's holdings.

RISKS: Investments in small- and medium-capitalization companies may involve a
higher degree of risk and volatility than investments in larger, more
established companies. The fund may invest in high yield and foreign securities,
including those in emerging markets, which involve risks beyond those inherent
in higher-rated and domestic investments. High yield bonds involve greater
credit and liquidity risks than investment grade bonds. Investing in foreign
securities is subject to certain risks not associated with domestic investing,
such as currency fluctuations and changes in political and economic conditions.
These risks are magnified in emerging or developing markets. The fund may use
derivatives, such as options and futures, which can be illiquid, may
disproportionately increase losses, and have a potentially large impact on fund
performance.

All index performance reflects no deduction for fees, expenses or taxes. Please
note that an investor cannot invest directly in an index.

Notes to Financial Statements (unaudited)


1.  SIGNIFICANT ACCOUNTING POLICIES

Salomon Brothers Opportunity Fund Inc ("Fund") is registered as a
non-diversified, open-end management investment company under the Investment
Company Act of 1940, as amended. The Fund's primary objective is to achieve
above average long-term capital appreciation. Current income is a secondary
objective. The following is a summary of significant accounting policies
consistently followed by the Fund in the preparation of its financial
statements. The policies are in conformity with accounting principles generally
accepted in the United States of America ("GAAP"). The preparation of financial
statements in accordance with GAAP requires management to make estimates of
certain reported amounts in the financial statements. Actual amounts could
differ from those estimates.

    (A) SECURITIES VALUATION. Portfolio securities listed or traded on national
securities exchanges or reported on the NASDAQ National Market System for which
market quotations are available are valued at the official closing price. If
there is no official closing price, the securities are valued at the last sale
price or, if there have been no sales that day, at the mean of the current bid
and asked prices which represents the current value of the security.
Over-the-counter securities are valued at the mean of the current bid and asked
prices. If no quotations are readily available (as may be the case for
securities of limited marketability), or if "restricted" securities are being
valued, such portfolio securities and other assets are valued at fair value
determined pursuant to procedures established by the Board of Directors.
Securities that are primarily traded on foreign exchanges generally are valued
at the preceding closing values of such securities on their respective
exchanges, except that when an occurrence subsequent to the time a value was so
established is likely to have changed such value, then the fair value of those
securities may be determined by consideration of other factors by or under the
direction of the Board of Directors or its delegates. In valuing assets, prices
denominated in foreign currencies are converted to U.S. dollar equivalents at
the current exchange rate. Securities may be valued by independent pricing
services which use prices provided by market-makers or estimates of market
values obtained from yield data relating to instruments or securities with
similar characteristics. Short-term securities with less than 60 days remaining
to maturity when acquired by the Fund are valued at amortized cost, which
approximates market value.

    (B) FEDERAL INCOME TAXES. The Fund has complied and intends to continue to
comply with the provisions of the Internal Revenue Code of 1986, as amended,
applicable to regulated investment companies, and to distribute substantially
all of its taxable income and capital gains, if any, to its shareholders.
Therefore, no Federal income tax or excise tax provision is required.

    (C) DIVIDENDS AND DISTRIBUTIONS. The Fund declares and pays dividends from
net investment income and distributions from net realized gains, if any,
annually. Dividends and distributions to shareholders are recorded on the
ex-dividend date. The amount of dividends and distributions from net investment
income and net realized gains are determined in accordance with Federal income
tax regulations, which may differ from GAAP. Permanent book/tax differences are
reclassified within the capital accounts based on their Federal income tax basis
treatment; temporary differences do not require reclassifications. Dividends and
distributions which exceed net investment income and net realized gains for
financial reporting purposes but not for tax purposes are reported as dividends
in

                                                                         PAGE 11

excess of net investment income and distributions in excess of net realized
capital gains. To the extent they exceed net investment income and net realized
capital gains for tax purposes, they are reported as tax return of capital.

    (D) YEAR END TAX RECLASSIFICATIONS. The character of income and gains to be
distributed are determined in accordance with income tax regulations which may
differ from GAAP.

    (E) OTHER. Securities transactions are recorded as of the trade date.
Dividend income and dividends payable are recorded on the ex-dividend date.
Interest income is recognized when earned. Noncash dividend income is recorded
based on market or fair value of property received. Gains or losses on sales of
securities are calculated for financial accounting and Federal income tax
purposes on the identified cost basis.

2.  MANAGEMENT FEE AND OTHER TRANSACTIONS

The Fund retains Salomon Brothers Asset Management Inc ("SBAM"), an indirect
wholly-owned subsidiary of Citigroup Inc. ("Citigroup"), to act as investment
manager of the Fund, subject to the supervision by the Board of Directors of the
Fund. The management fee is payable monthly at an annual rate of 0.75% of the
Fund's average daily net assets. Prior to October 1, 2003 the Fund paid SBAM a
management fee at an annual rate of 1.00% of the Fund's average daily net
assets. SBAM has delegated certain administrative responsibilities to Smith
Barney Fund Management LLC ("SBFM"), another indirect wholly-owned subsidiary of
Citigroup, pursuant to a Sub-Administration Agreement between SBAM and SBFM.
SBFM has also entered into an agreement with State Street Bank &Trust ("SSB&T")
for the performance of certain Fund administrative functions. SBAM pays SBFM a
fee calculated daily and paid monthly, at an annual rate of 0.05% of the Fund's
average daily net assets and SBFM pays SSB&T out of this fee.

Citigroup Global Markets Inc., another indirect wholly-owned subsidiary of
Citigroup and an affiliate of SBAM, acts as the Fund's distributor.

Certain officers and/or directors of the Fund are also officers and/or directors
of SBAM.

The Fund has a concentration of several shareholders who may be a related party,
holding a significant percentage of shares outstanding. Investment activities of
these shareholders could have a material impact on the Fund.

4.  LENDING OF PORTFOLIO SECURITIES

The Fund has an agreement with its custodian whereby the custodian may lend
securities owned by the Fund to brokers, dealers and other financial
organizations, and receives a lenders fee. Fees earned by the Fund on securities
lending are recorded in interest income. Loans of securities by the Fund are
collateralized by cash, U.S. government securities or high quality money market
instruments that are maintained at all times in an amount at least equal to the
current market value of the loaned securities, plus a margin which may vary
depending on the type of securities loaned. The Fund maintains exposure for the
risk of any losses in the investment of amounts received as collateral.

At February 29, 2004, the Fund did not have any securities on loan.

Income earned by the Fund from securities lending for the six months ended
February 29, 2004 was $1,870.

7. ADDITIONAL INFORMATION

The Fund has received the following information from Citigroup Asset Management
("CAM"), the Citigroup business unit which includes the Fund's Investment
Manager and other investment advisory companies, all of which are indirect,
wholly-owned subsidiaries of Citigroup. CAM is reviewing its entry, through an
affiliate, into the transfer agent business in the period 1997-1999. As CAM
currently understands the facts, at the time CAM decided to enter the transfer
agent business, CAM sub-contracted for a period of five years certain of the
transfer agency services to a third party and also concluded a revenue guarantee
agreement with this sub-contractor providing that the sub-contractor would
guarantee certain benefits to CAM or its affiliates (the "Revenue Guarantee
Agreement"). In connection with the subsequent purchase of the sub-contractor's
business by an affiliate of the current sub-transfer agent (PFPC Inc.) used by
CAM on many of the funds it manages, this Revenue Guarantee Agreement was
amended eliminating those benefits in exchange for arrangements that included a
one-time payment from the sub-contractor.

The Boards of CAM-managed funds (the "Boards") were not informed of the Revenue
Guarantee Agreement with the sub-contractor at the time the Boards considered
and approved the transfer agent arrangements. Nor were the Boards informed of
the subsequent amendment to the Revenue Guarantee Agreement when that occurred.

CAM has begun to take corrective actions. CAM will pay to the applicable funds
approximately $17 million (plus interest) that CAM and its affiliates received
from the Revenue Guarantee Agreement and its amendment. CAM also plans an
independent review to verify that the transfer agency fees charged by CAM were
fairly priced as compared to competitive alternatives. CAM is instituting new
procedures and making changes designed to ensure no similar arrangements are
entered into in the future.

CAM has briefed the SEC, the New York State Attorney General and other
regulators with respect to this matter, as well as the U.S. Attorney who is
investigating the matter. CAM is cooperating with governmental authorities on
this matter, the ultimate outcome of which is not yet determinable.

The Fund's transfer agent is PFPC Inc., which is not affiliated with CAM.
