Growth Fund Inc.
================================================================================

The Smith Barney Aggressive Growth Fund Inc. seeks capital appreciation through
investment primarily in common stocks of companies that the investment advisor
believes are experiencing, or have the potential to experience, growth in
earnings or cash flow that exceeds the average growth rate of companies whose
securities are included in the S&P 500 Index. They are often small- or
medium-sized companies that stand to benefit from new products or services,
technological developments or changes in management.

Dear Shareholder:

We are pleased to provide the semi-annual report for the Smith Barney Aggressive
Growth Fund for the six months ended February 28, 1997. In this report, we
summarize the period's prevailing economic and market conditions and outline our
portfolio strategy. A detailed summary of the Fund's performance and current
holdings can be found in the appropriate sections that follow in the report.

Fund Performance

For the period under review we are pleased to report that the Smith Barney
Aggressive Growth Fund's Class A shares had a total return of 21.48%. During the
period, the Fund outperformed the broadly based Russell 2000 Index* and the
Value Line Composite Index (Arithmetic),** major indices which we believe
represent a good measure of performance for the kinds of securities held in the
Fund. For example, the Russell 2000 advanced approximately 8% while the Value
Line Composite Index (Arithmetic) registered a gain of 15% during the reporting
period. In comparison, the Standard & Poor's 500 Composite Index (S&P 500),***
an index that is more representative of large-capitalization companies, advanced
22.52%. Keep in mind that these figures represent past performance and are not a
guarantee of future results.

During the past six months, the Aggressive Growth Fund's most significant gains
came from select technology companies, including Quantum Corporation, Micron
Technology and Intel Corporation (the Fund's largest holding as of February 28,
1997). Strong gains in brokerage firm stocks, specifically Merrill Lynch and
Lehman Brothers also contributed to the Fund's recent performance. In addition,
a notably strong recovery in managed health care stocks owned by the Aggressive
Growth Fund, such as United Healthcare and Aetna also helped boost its
performance.

Energy Ventures, an oil-field equipment supplier, also contributed to the Fund's
positive performance. Tyco International, a fast-growing producer of fire
protection and other industrial equipment and the Fund's second largest holding,
continued to report outstanding earnings and announced a series of acquisitions
to expand its business. In addition, even though we believe significant progress
has been made by many of the Aggressive Growth Fund's biotechnology company
holdings, their share prices rose only marginally during the reporting period.

Market Overview

Following the market lows reached during July 1996, the leadership that
eventually developed in the stock market was concentrated mostly in large,
multinational companies. As the past six months drew to a close, the decided
preference of many investors for large- capitalization companies rather than
smaller- and middle-capitalization ones intensified.

Interest rates, which rose above 7% early in the summer of 1996, helped
precipitate a sharp but brief decline in the market, with the S&P 500 dropping

**   The Value Line Composite Index is composed of the 1,700 stocks tracked by
     the Value Line Investment Survey.

***  The S&P 500 Index is a capitalization-weighted measure of 500 widely held
     common stocks.

nearly 10% and the Nasdaq Composite Index**** falling by roughly 20%. However,
long-term interest rates eased off to approximately 6.5% during the latter part
of 1996, and that enabled the major averages to reach all-time highs this
February.

Many investors during the past six months grew increasingly concerned about the
Federal Reserve Board's ("Fed") monetary policy which had been accommodative for
nearly two years. Although most U.S. government-sponsored indicators of
inflation have remained quite benign, the pace of economic growth has not
slowed, a factor that has raised fears at the Fed about a possible future pickup
in inflation. Moreover, Fed Chairman Alan Greenspan added another element of
uncertainty recently to the financial markets when he cited the high level of
stock prices as a factor that should be considered when setting monetary policy.
Interest rates increased toward the end of February 1997 under the possibility
of a shift in the Fed's monetary policy. (This shift did occur, in late March,
when the Fed raised short-term interest rates by 0.25%.)

Investment Strategy and Outlook

The Smith Barney Aggressive Growth 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 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 linear
fashion. Nevertheless, provided these young and innovative companies are able to
generate above-average earnings growth and sell at a reasonable multiple of
those earnings, they usually remain a Fund holding.

For example, Tyco International, one of the Fund's original holdings, has been
in the portfolio since 1983 even though its market capitalization has grown from
$400 million when purchased to more than $9 billion currently. In fact, Tyco's
growth rate in earnings per share is as rapid today as it was thirteen years ago
when it met the original investment parameters of the Fund. As a general rule,
we focus on companies with sales and earnings that are not overly dependent on
movements in the general economy but rather on the generation of new products.

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 prefer 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 its 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.

In a volatile and sometimes emotionally driven market, we also believe it is
critically important to own stocks of companies with earnings that have the
potential to at least meet the expectations of investors. With the
price-to-earnings ratio on the S&P 500 at a historically high level, we believe
that the risk/reward ratio is now far more attractive for many secondary growth
stocks that are owned by the Aggressive Growth Fund. (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.) Moreover, we favor companies that sell for P/E multiples less than
one times their expected earnings growth rate rather than pay the "stretched"
levels of many large-capitalization companies.

We remain particularly optimistic today about select biotechnology stocks and
managed health care providers. In our view, an increasing number of
biotechnology companies will successfully make the transition from companies in
their developmental stage to profit-generating enterprises in 1997. In

addition, we believe the pricing environment for select health maintenance
organizations is much improved this year and investor expectations for earnings
growth in this sector are too cautious. Unless long-term interest rates decline
in 1997, we do not expect the P/E ratio or the market to expand, and therefore
performance for most stocks will be driven primarily by earnings growth.

In closing, thank you for your investment in the Smith Barney Aggressive Growth
Fund and your continued confidence in our investment management approach. We
look forward to communicating with you at the end of the Aggressive Growth
Fund's fiscal year.

Sincerely,

  An Interview with Portfolio Manager
  Richard A. Freeman
================================================================================

A Disciplined Approach 
To Growth Investing


Richard Freeman is a Managing Director of Smith Barney and has been the
portfolio manager of the Aggressive Growth Fund since it began in October 1983.
In addition, Mr. Freeman also manages growth portfolios for high net worth
individuals and institutional accounts. He began his investment career as an
aerospace and electrical equipment analyst with Drexel Burnham Lambert and later
with Chemical Bank. He then became a portfolio manager in 1983 when the Smith
Barney Aggressive Growth Fund was launched. He holds a BS in accounting from
Brooklyn College and an M.B.A. from New York University. Peter Bourbeau, a Smith
Barney Vice President, joined the discussion to talk about the team's approach
to investment management and research.

Richard and Peter, how would you describe the Fund's investment strategy?

Richard: The Smith Barney Aggressive Growth Fund has maintained a consistent
investment strategy since its inception and is managed much more like a
traditional "buy and hold" growth fund. This explains the very low turnover in
the portfolio and our long-term investment horizon.

As disciplined, "bottom up" investors, we try to identify the stocks of
companies with outstanding growth potential that can grow their earnings
rapidly. We generally do not consider the impact of broad economic trends or try
to make economic forecasts. In addition, while the Fund continues to be well
diversified across different industries and market sectors, we typically
maintain approximately 60 positions in the Fund. This enables us to monitor each
company's specific situation carefully and better evaluate its long-term growth
prospects and earnings potential.

Peter: We maintain an ongoing dialogue with the managers of many companies and
former company officials in different industries. This kind of active, hands-on
research gives us insight as to how these corporations are run and often enables
us to anticipate major changes that may positively affect an industry or
company.

At the end of the reporting period, the Smith Barney Aggressive Growth Fund
continued to emphasize health care and technology stocks. Have the health care
and technology industries always been a major focus of the Fund?

Richard: No. One of the key elements of our investment philosophy is that we
want to own great companies no matter what industry they are in. For example, in
the mid-1980s, more than one-third of the Aggressive Growth Fund's assets was
invested in consumer stocks in the retailing and broadcasting industries. At
that time we believed that the risk/reward ratio for these select consumer
stocks was extremely attractive.

Peter: We continue to evaluate opportunities for the Smith Barney Aggressive
Growth Fund on a stock-by-stock basis. It just so happens that the stocks of
companies in expanding industries such as biotechnology and health care have in
recent years met the Fund's investment criteria.


Richard: I have been following the stock market closely since the mid-1960s and
have seen the passage of numerous market cycles. In my view, a well-designed
growth fund should own companies that will be top performers over five or ten
years rather than winners for just one or two quarters. The Smith Barney
Aggressive Growth Fund tries to own companies that should be able to expand
their business regardless of the condition of the economy or the direction of
interest rates. In addition, the Fund looks for companies that can develop new
product lines that will make some of their existing products obsolete.

<PAGE>
 
Richard, what would you be doing today if you weren't a portfolio manager?


Richard: In truth, I've never wanted to be anything else but a portfolio
manager. On my thirteenth birthday, I remember I was given ten shares of an
Alaskan mining company called AJ Industries. I recall tracking my holding
closely and every time the `AJ' symbol came across the ticker I got a very big
thrill. In fact, the stock market has been my hobby since that time and my
vocation since I was twenty-two years old. However, if there were 48 hours in a
day, in addition to being a portfolio manager I would also want to be the
general manager of a major league baseball team. Of course, my office would
overlook the diamond, giving me the best seat in the house.


Discussion of Top Five Holdings

Portfolio Manager Richard Freeman recently discussed the Fund's top five
holdings as of February 28, 1997 and why he believes they represent compelling
long-term investment opportunities.

Intel Corp. is the world's largest manufacturer of current and next generation
semiconductor chips used primarily in personal computers. With more than $20
billion in revenues, $5 billion in cash, a majority market share and strong
earnings growth, we see Intel as a premier way to participate in the domestic
and global technology explosion currently underway. In our opinion, increasingly
complex software, video conferencing and the rising use of the Internet should
be strong future drivers of personal computer demand.

Tyco International Ltd. is a global leader in fire protection equipment, flow
control products and disposable medical supplies. In addition to having strong
management, the company augments its growth by making acquisitions that help
drive earnings. Another positive for Tyco is the fact that a large amount of its
management's compensation is tied to the performance of its business units and
future earnings growth.

Quantum Corp. is a leading supplier of computer storage devices including disk
and tape drives used in work-stations, servers and desk-top personal computers.
Quantum is enjoying a significant increase in profitability while exhibiting
continued good revenue growth. As significant consolidation has occurred in the
disk drive industry during the past several years, we believe this trend should
lead to more rational pricing and better profitability for the remaining
vendors. Currently, Quantum's stock sells at a discount to the company's
revenues, which is often a good benchmark of value for a technology company.

United Healthcare Corp. is the largest publicly traded pure health maintenance
organization in the U.S. With strong enrollment growth, $3 billion in cash and a
relatively untapped commercial market, United Healthcare remains the undisputed
leader in the industry. In our view, health maintenance organizations stand to
benefit from the proposed privatization of Medicare and Medicaid. In addition,
we favor United Healthcare because management, which pioneered the HMO concept,
is heavily incentivized with stock pegged to earnings-per-share growth.

Amgen Inc. is the world's largest and most profitable biotechnology company. It
has annual sales of more than $2 billion and net income margins of more than
30%. Neupogen and Epogen, white and red blood cell simulators respectively,
comprise 85% of the company's revenue. In addition, Amgen has formed strategic
alliances with leading universities and other biotechnology firms to complement
as well as advance its current internal research efforts.

(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 charge 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 February 28, 1997 since all Class Y shares redeemed during
     November, 1995.

* Hypothetical illustration of $10,000 invested in Class A shares on February
28, 1987, 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, 1997. 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. 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.

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 the 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; (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. At August 31, 1996, 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, a
portion of undistributed net investment income amounting to $989 has been
reclassified to paid-in capital. Net investment income, net realized gains and
net assets were not affected by this change; (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; and (j) 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

Smith Barney Mutual Funds Management Inc. ("SBMFM"), a subsidiary of Smith
Barney Holdings Inc. ("SBH"), acts as investment adviser to the Fund. The Fund
pays SBMFM 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.


SBMFM 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 SBH, acts as distributor of Fund
shares and primary broker for its portfolio agency transactions. For the six
months ended February 28, 1997, SB received sales charges of approximately
$137,000 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,

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 Portfolio requires continual
maintenance of the market value of the collateral in amounts at least equal to
the repurchase price.

5.   Capital Shares

At February 28, 1997, the Fund had 100 million shares of capital stock
authorized with a par value of $0.01 per share. The Fund has the ability to
issue multiple classes of shares. Each share of a class represents an identical
interest and has the same rights, except that each class bears certain expenses,
including those specifically related to the distribution of its shares.

At February 28, 1997, total paid-in capital amounted to the following for each
class:
