FUND HIGHLIGHT
================================================================================

The Smith Barney Aggressive Growth Fund remains committed to generating
above-average returns for our shareholders. One important by-product of our
long-term, low-turnover investing approach is the potential to achieve superior
after-tax returns for our investors. We are strong believers in the philosophy
behind the expression, "it's not what you make, but what you keep that counts."

Market Overview

Although the stock market finished higher than it began during the reporting
period, greater levels of volatility characterized the period under review. In
the past several years, investors have displayed a decided preference for the
shares of large-capitalization companies. However, a brief period of
outperformance for small- and mid-capitalization stocks versus
large-capitalization stocks occurred from May into September. (Market
capitalization is the market value of a company's outstanding shares of common
stock determined by the number of shares outstanding multiplied by the share
price.)

While the U.S. economy continued to perform almost flawlessly and was marked by
low rates of inflation, strong economic growth and robust corporate profits,
events in Asia began to cast an ominous pall over worldwide stock markets as the
summer drew to a close. Dramatic declines in many Asian currencies contributed
to sharp declines in their respective stock markets, fueling an overall decrease
in wealth and contraction of Asian economic activity. The Asian "contagion" had
a domino effect on other world stock markets with the pervasive fear that
companies that sell a portion of their goods to Asia would experience a slowdown
in their own businesses.

For the first time since 1990, the U.S. stock market, as represented by the S&P
500 Index, sustained a greater than 10% correction culminating in a 7% one day
drop in October. (The S&P 500 Index is a

capitalization-weighted measure of 500 widely held common stocks.) This was the
fourth such significant decline experienced by smaller company stocks since
1994. Following the stock market lows in late October, the divergence in
performance between large- and small-company stocks returned as investors again
gravitated toward large-company stocks even though their earnings in many cases
were more vulnerable to the fallout from Asia than many pure domestic small-cap
companies.

One positive ramification for the U.S. from the crisis in Asian has been a
decline in interest rates, inflation and import prices. In addition, the Federal
Reserve Board's ("Fed") monetary policy and its previous bias toward tightening
has shifted to neutral as some Fed members have expressed concerns that the U.S.
economy could be negatively impacted by the situation in Asia.

Investment Strategy

The Fund's strategy continues to be to invest in young, innovative companies in
dynamic industries that we believe have the potential to generate above-average
growth in earnings and/or cash flow over a three-to-five year period. Ideally,
this growth should come smoothly, immediately and predictably. However,
investing in these kinds of young and innovative companies often means growth
does not necessarily proceed in a straightline. Nevertheless, if these
relatively new and dynamic companies are able to generate above-average earnings
growth and sell at a reasonable multiple of those earnings, they usually remain
a Fund holding.

Traditionally, our holdings reinvest significant sums of capital back into their
businesses, with research and development spending often a meaningful percentage
of revenues. In addition, we also tend to favor companies that keep their
product lines fresh. While investment spending may at times hold back the
near-term earnings of these types of companies, we believe it is a necessary
strategy to drive their long-term growth rates. Moreover, we prefer to own
companies whose management teams are given incentive through the performance of
their stock. When the stock underperforms, we want management to be as concerned
as we are. In addition, while large stock holdings by management do not
guarantee rising stock prices, we believe it does increase the likelihood that
management will take remedial steps to improve the price of the stock if they
have a big ownership stake.

Market Outlook

Three important factors continue to positively affect the U.S. stock market:

     o    Low interest rates

     o    Continued positive inflows into mutual funds

     o    Intense merger and stock buyback activity

For the first time in a generation, Washington, D.C. is forecasting a budget
surplus. Years of uninterrupted economic growth leading to a low rate of
unemployment (contributing to smaller government transfer payments) is one
factor leading to the improved budgetary condition. Another factor is the
significant increase in capital gains generated by the high level of the stock
market and cash merger activity. The decline in the maximum rate on long-term
capital gains from 28% to 20% last summer has made some investors less reluctant
to sell their holdings given the more favorable tax treatments. Moreover, we
believe that stock buybacks and merger activity are even more important factors
behind the market's incredible climb than the publicized inflow of large sums of
money into mutual funds.

The Fund remains committed to generating above-average returns for our
shareholders. One important by-product of our long-term, low-turnover investing
approach is the potential to achieve superior after-tax returns for our
investors. We are strong believers in the philosophy behind the expression,
"it's not what you make, but what you keep that counts."

During the reporting period, we added to our positions in Amgen (biotechnology
company), Netscape (internet software company), Excel Technology (commercial
laser

technologies company), and EVI (oil field service equipment company). We sold
Computervision and Technologies Modelling Associates, two technology companies,
following their acceptances of takeover offers.

We also sold our positions in Gulfmark Offshore (energy company), Synaptic
Pharmaceuticals (biotechnology company), Dennison International (hydraulics
manufacturing company) and Metra Biosystems (biotechnology company). We tendered
our Tele-Communications Inc. stock receiving shares in TCI Ventures for about
1/3 of our shares. Following a couple of years of underperformance, when
investors shunned the stocks of cable television operators, the group has now
reached all-time highs. Strong growth in cash flows, exciting new revenue
streams and a business unencumbered by worries over Asia turned the shares from
"value" investments into strong growth stocks once again.

While overall corporate earnings may come under some pressure because of weak
business conditions in Asia, those companies that are able to report favorable
relative earnings will likely see their P/E ratios rise in an environment of low
inflation and low interest rates. (The P/E ratio, or price-to-earnings ratio, is
a common method used by investors to determine a stock's relative value. The P/E
ratio compares a stock's price to its earnings per share.) We believe that the
Fund is well positioned to benefit from these expected conditions.

In closing, thank you for your confidence in our investment approach. We look
forward to helping you pursue your financial goals in the year ahead.


Sincerely,


/s/ Heath B. McLendon               /s/ Richard A. Freeman

(1)  Assumes reinvestment of all dividends and capital gain distributions, if
     any, at net asset value and does not reflect deduction of the applicable
     sales charges with respect to Class A shares or the applicable contingent
     deferred sales charges ("CDSC") with respect to Class B and Class C shares.
(2)  Assumes reinvestment of all dividends and capital gain distributions, if
     any, at net asset value. In addition, Class A shares reflect the deduction
     of the maximum initial sales charge of 5.00% and Class B shares reflect the
     deduction of a 5.00% CDSC, which applies if shares are redeemed within one
     year from initial purchase. Thereafter, the CDSC declines by 1.00% per year
     until no CDSC is incurred. Class C shares reflect the deduction of a 1.00%
     CDSC which applies if shares are redeemed within the first year of
     purchase.
*    Inception dates for Class A, B, C, Y and Z shares are October 24, 1983,
     November 6, 1992, May 13, 1993, October 12, 1995 and November 6, 1992,
     respectively.
+    Total return is not annualized, as it may not be representative of the
     total return for the year.
++   Performance for Class Y shares is for the period from January 31, 1996
     through August 31, 1996 since all Class Y shares redeemed during November
     1995 and new shares in Class Y were not purchased until January 31, 1996.

+    Hypothetical illustration of $10,000 invested in Class A shares on February
     29, 1988, assuming deduction of the maximum 5.00% sales charge at the time
     of investment and reinvestment of dividends and capital gains, if any, at
     net asset value through February 28, 1998. The Value Line Composite Index
     is composed of approximately 1,700 stocks. The Geometric Index is a
     geometric average of the daily price percentage change in each stock
     covering both large and small capitalized companies. The Arithmetic Index
     is an arithmetic average of the daily price percentage change in each stock
     covering both large and small capitalized companies. Russell 2500 Growth
     Index measures the performance of those Russell 2500 companies with higher
     price-to-book ratios and higher forecasted growth values. The indexes are
     unmanaged and are not subject to the same management and trading expenses
     as a mutual fund. The performance of the Fund's other classes may be
     greater or less than the Class A shares' performance indicated on this
     chart, depending on whether greater or lesser sales charges and fees were
     incurred by shareholders investing in the other classes.

     All figures represent past performance and are not a guarantee of future
     results. Investment returns and principal value will fluctuate, and
     redemption values may be more or less than the original cost. No adjustment
     has been made for shareholder tax liability on dividends or capital gains.

++   It is the opinion of management that the Russell 2500 Growth Index more
     accurately reflects the current composition of the Smith Barney Aggressive
     Growth Fund Inc. than the Value Line Composite Index. In future reporting,
     the Russell 2500 Growth Index will be used as a basis of comparison of
     total return performance rather than the Value Line Composite Index.

1.   Significant Accounting Policies

The Smith Barney Aggressive Growth Fund Inc. ("Fund"), a Maryland corporation is
registered under the Investment Company Act of 1940, as amended, as a
diversified, open-end management investment company.

The significant accounting policies consistently followed by the Fund are: (a)
security transactions are accounted for on trade date; (b) securities traded on
national securities markets are valued at the closing prices on such markets;
securities for which no sales price was reported and U.S. government and agency
obligations are valued at the bid price. Investments in securities for which
market quotations are not available are valued at fair value as determined in
good faith by the Board of Directors; (c) securities maturing within 60 days are
valued at cost plus accreted discount, or minus amortized premium, which
approximates value; (d) dividend income is recorded on the ex-dividend date and
interest income is recorded on an accrual basis; (e) gains or losses on the sale
of securities are calculated by using the specific identification method; (f)
direct expenses are charged to each class; investment advisory fees and general
Fund expenses are allocated on the basis of relative net assets by class; (g)
dividends and distributions to shareholders are recorded on the ex-dividend
date; (h) the character of income and gains to be distributed are determined in
accordance with income tax regulations which may differ from generally accepted
accounting principles; (i) the Fund intends to comply with the applicable
provisions of the Internal Revenue Code of 1986, as amended, pertaining to
regulated investment companies and to make distributions of taxable income
sufficient to relieve it from substantially all Federal income and excise taxes;
(j) the character of income and gains to be distributed are determined in
accordance with income tax regulations which may differ from generally accepted
accounting principles. At August 31, 1997, reclassifications were made to the
Fund's capital accounts to reflect permanent book/tax differences and income and
gains available for distributions under income tax regulations. Accordingly, an
accumulated net investment loss of $6,945,780 and $20,005 of accumulated net
realized gains were reclassified to paid-in capital. Net investment income, net
realized gains and net assets were not affected by this adjustment; and (k)
estimates and assumptions are required to be made regarding assets, liabilities
and changes in net assets resulting from operations when financial statements
are prepared. Changes in the economic environment, financial markets and any
other parameters used in determining these estimates could cause actual results
to differ.

2.   Investment Advisory Agreement, Administration Agreement and Other
     Transactions

Mutual Management Corp. ("MMC"), formerly known as Smith Barney Mutual Funds
Management Inc., a subsidiary of Salomon Smith Barney Holdings Inc. ("SSBH"),
acts as investment adviser to the Fund. The Fund pays MMC an advisory fee
calculated at an annual rate of 0.60% of the average daily net assets. This fee
is calculated daily and paid monthly.

MMC also acts as the Fund's administrator for which the Fund pays a fee
calculated at an annual rate of 0.20% of the average daily net assets. This fee
is calculated daily and paid monthly.

Smith Barney Inc. ("SB"), another subsidiary of SSBH, acts as distributor of
Fund shares and primary broker for its portfolio agency transactions. For the
six months ended February 28, 1998, SB received sales charges of approximately
$372,000 on sales of the Fund's Class A shares.

There is a contingent deferred sales charge ("CDSC") of 5.00% on Class B shares,
which applies if redemption occurs less than one year from initial purchase and
declines thereafter by 1.00% per year until no

CDSC is incurred. Class C shares have a 1.00% CDSC, which applies if redemption

================================================================================

Pursuant to a Distribution Plan the Fund pays a service fee with respect to its
Class A, B and C shares calculated at the annual rate of 0.25% of the average
daily net assets of each respective class. The Fund also pays a distribution fee
with respect to Class B and C shares calculated at the annual rate of 0.75% of
the average daily net assets of each class, respectively. For the six months
ended February 28, 1998, total Distribution Plan fees were as follows:

4.   Repurchase Agreements

The Fund purchases (and its custodian takes possession of) U.S. government
securities from banks and securities dealers subject to agreements to resell the
securities to the sellers at a future date (generally, the next business day),
at an agreed-upon higher repurchase price. The Fund requires continual
maintenance of the market value of the collateral in amounts at least equal to
the repurchase price.

5.   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. Fees earned by the Fund on securities lending are recorded as
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 custodian establishes and maintains the collateral in a
segregated account. The Fund maintains exposure for the risk of any losses in
the investment of amounts received as collateral. 

At February 28, 1998, the Fund loaned common stocks having a value of
approximately $126,137,626 and holds the following collateral for loaned
securities:
