Dear Monetta Shareholder:                                July 26, 2004

The stock market continued its seesaw action during the second quarter, as
leading economic indicators remained range-bound all year.  Although the growth
in the economy has shown signs of improvement it has been difficult to make
money in the equity markets.  For example, even though earnings are exceeding
estimates by a large amount, stocks refuse to budge.  Even a low interest rate
environment with moderate inflationary pressures has not helped the stock
market.  The markets appear to be in a consolidation phase, digesting the gains
of last year while feeling anxiety about the U.S. presidential election and the
situation in Iraq.

The biggest near-term risk to the financial markets appears to be the degree of
emerging inflation and the extent that it could impact corporate earnings in
2005.  The market appears to be signaling concerns over the sustainability of
current economic growth.  For example, although new hiring activity has picked
up, it has not been robust enough to materially impact the unemployment rate.
Also, wage growth has remained subdued in spite of significant fiscal stimulus
to propel consumer spending and corporate earnings.

The market is basically suffering from a loss of momentum.  Investors are not
sure which sectors to invest in as no group other that Energy has demonstrated
leadership characteristics.  If the economy slows down investors will likely
move into the health care and consumer staples groups.  Conversely, if we see
continued economic strength in the second half of 2004, economically sensitive
groups such as technology and consumer discretionary should perform well.

We believe that excess capacity and improved productivity will minimize
inflation from becoming a serious problem.  As the economic recovery matures
into a solid expansion phase the bull market could get another powerful leg up,
especially with an added boost from some unexpected sources i.e., China, U.S.
dollar strength, oil prices etc.

In terms of the fixed income market the Federal Reserve formally acknowledged
the economic recovery when they raised the federal funds rate up 0.25% to
1.25%.  The question now becomes how quickly the Fed will raise rates to keep
inflation in check.  Based on the delicate nature of this recovery we do not
expect a significant increase in interest rates.

COMMENTARY

The Monetta Fund posted a return of negative 5.76% in the first half of 2004,
compared to the Russell 3000 Growth Index and S&P 500 Index returns of 5.68%
and 3.44%, respectively.   After beating the S&P 500 Index returns in both 2002
and 2003,  (-15.2% vs. -22.09% and 2.81% vs. 0.25%, respectively), we are
disappointed to be behind thus far in 2004.

After a strong performance in 2003, the market continued to move upward in
early 2004.  Our strategy was to stay in the more volatile stocks that had
performed well and had been demonstrating strong fundamentals in terms of
earnings and revenue growth.  Unfortunately, after a strong start in January
many of these stocks began to perform poorly.  Initially, we felt that this was
a healthy pullback after strong performance in 2003.   It became evident last
quarter, however, that investors were leaving economically sensitive groups and
rotating into more defensive groups.

In response to what the market is telling us we have recently moved into a more
defensive posture.  We are currently overweighted in the energy group, and are
underweighted in the technology and consumer discretionary groups.  At this
point we are attempting to determine whether this is a temporary rotation into
defensive groups, or if we are entering an economic slowdown.

The Monetta Fund had a number of stocks that have performed well thus far in
2004. Specifically, Peabody Energy and Valero Energy Corp. posted strong gains,
and represented 2.4% and 0.5% of net assets, respectively, on June 30, 2004.
Peabody Energy is a coal producer and Valero Energy is an oil refiner.  Our
weakest sector this year has been the home building stocks.  As reported in our
2003 report, home building stocks were our best performers in 2003.  Despite
strong fundamentals, investors are currently leaving the group due to concerns
over higher interest rates.  We have reduced our home building stocks, due to
their lack of performance.

We are concerned about the conflicting signals that we are getting about the
economy.  It is difficult to ascertain whether we are entering an economic
slowdown, or if the economy is just resting for a pickup later in the year.
This will have a major impact on how we position the portfolio to best take
advantage of the economic situation.

Notes To Financial Statements                                    June 30, 2004

1.     SIGNIFICANT ACCOUNTING POLICIES:

Monetta Fund, Inc. (Monetta Fund) is an open-end diversified management
investment company registered under the Investment Company Act of 1940, as
amended. The objective of the Monetta Fund is capital appreciation by investing
primarily in equity securities believed to have growth potential. The Fund
generally invests in companies with a market capitalization of under $3
billion. Effective January 1, 2003, the market capitalization restriction was
removed. The Fund invests primarily in growth companies of all market
capitalization ranges.

The following is a summary of significant accounting policies followed by the
Fund in the preparation of its financial statements in accordance with
generally accepted accounting principles:

(a)    Securities Valuation
Investments are stated at market value based on the last reported sale price on
national securities exchanges, or the NASDAQ Market, on the last business day
of the period. Listed securities and securities traded on the over-the-counter
markets that did not trade on the last business day are valued at the mean
between the quoted bid and asked prices. Short-term securities are stated at
amortized cost, which is substantially equivalent to market value.

(b)    Use of Estimates
The preparation of financial statements, in conformity with accounting
principles generally accepted in the United States of America, requires the
Fund's management to make estimates and assumptions that affect reported
amounts of assets and liabilities and disclosures of contingent assets and
liabilities at the date of the financial statements and the results of
operations during the reporting period. Actual results could differ from those
estimates.

(c)    General
Security transactions are accounted for on a trade date basis. Daily realized
gains and losses from security transactions are reported on the first-in,
first-out cost basis. Interest income is recorded daily on the accrual basis
and dividend income on the ex-dividend date.

(d)    Federal 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. Accordingly, no
provision for federal income taxes is required.  It is the Board's intent not
to distribute any realized gains until the capital loss carry forwards have
been offset or expired.

The Fund intends to utilize provisions of the federal income tax laws which
allow them to carry a realized loss forward for eight years following the year
of the loss and offset such losses against any future realized capital gains.
At December 31, 2003, the losses amounted to $23,646,739, which will expire
between December 31, 2009 and December 31, 2011.

Net realized gains or losses differ for financial reporting and tax purposes as
a result of losses from wash sales, post October 31 losses which are not
recognized for tax purposes until the first day of the following fiscal year,
and gains and losses from real estate investment trusts.


<PAGE 10>


Notes To Financial Statements                                   June 30, 2004

(e)    Distribution of Income and Gains
Distributions to shareholders are recorded by the Fund on the ex-dividend date.
Due to inherent differences in the characterization of short-term capital gains
under accounting principles generally accepted in the United States of America
and for federal income tax purposes, the amount of distributable net investment
income for book and federal income tax purposes may differ.

For federal income tax purposes, a net operating loss recognized in the current
year cannot be used to offset future year's net investment income. For the year
ended December 31, 2003, the Monetta Fund had net operating losses of $356,241
for tax purposes which were reclassified from accumulated undistributed net
investment income to capital.

The Fund had no distributions for the year ended December 31, 2003.

2. RELATED PARTIES:
Robert S. Bacarella is an officer and director of the Fund and also an officer,
director and majority shareholder of the investment adviser, Monetta Financial
Services, Inc. (Adviser). For the six months period ended June 30, 2004,
renumerations required to be paid to all interested directors have been
absorbed by the Adviser. Fees paid to outside Directors have been absorbed by
the Fund.

The Fund pays an investment advisory fee to the Adviser based on the Fund's
individual net assets, payable monthly at the following annual rate:

       First $300 million in     Next $200 million in       Net assets over
           net assets               net assets                $500 million

             0.95%                      0.90%                      0.85%



From this fee the Adviser pays for all necessary office facilities, equipment
and personnel for managing the assets of the fund. In addition, the Adviser
pays for all expenses in determining the daily price computations, placement of
securities orders and related bookkeeping.
