Dear Shareholder:

  The net asset value of the Zweig Fund, Inc. decreased 16.4% during the three
months ended September 30, 2001, including the $0.22 distribution paid on July
26, 2001. During the same period, the S&P 500 Index declined 14.7%, including
dividends. The Fund's exposure during the third quarter averaged approximately
97%.

  For the nine months ended September 30, 2001, the Fund's net asset value
declined 24.3%, including $0.71 in distributions. During this span, the S&P
500 Index fell 20.4%, including dividends. Our average exposure for this
period was 96%.

  The third quarter was a difficult one for the equity markets. The Dow Jones
Industrial Average dropped 15.8%, its worst showing since the last quarter of
1987. The Nasdaq composite declined 31%, and the S&P 500 Index, as noted
above, was down nearly 15%./1/ According to Lipper Inc., 99% of equity mutual
funds finished the quarter in the red, and the average diversified mutual fund
dipped 16.2%.

  In line with our indicators, which have served us so well in the past, we
were bullish during the quarter for the following reasons.
--------
/1/The Dow Jones Industrial Average and the S&P 500 Index measure broad stock
  market total-return performance. The Nasdaq composite measures technology-
  oriented stock total-return performance. All of the indices are unmanaged
  and not available for direct investment.
                                                               November 1, 2001

Historically, going back to 1913, there have been roughly 11.9 cumulative
years when we were in a similar mode--three or more Federal Reserve interest
rate cuts and a growing money supply--and the average annual return for the
S&P 500 during that period was 32.8%. The average rate of return for the
remaining 76 years was in the vicinity of 2.2%.

  That is basically why we were bullish. Other indicators pointed in the same
direction. What went wrong--and that was before the terrorist attacks on
September 11--is that I underestimated the impact of the bursting of the
technology bubble on the market and the economy. I thought the Fed actions
would induce capital expenditures in other areas sooner and stimulate consumer
spending. The housing market, for example, did show improvement. However,
conditions unexpectedly worsened in August and the events of September 11 only
exacerbated the market's weakness.


                             DISTRIBUTION DECLARED

  On September 20, 2001, the Fund announced a distribution of $0.18 payable on
October 26, 2001, to stockholders of record as of October 10, 2001. Including
this distribution, our total payout since the Fund's inception is now $16.73.


                                MARKET OUTLOOK

  The World Trade Center attack is perhaps the equivalent of a 1000-year
flood. It presents an entirely new and different set of largely unpredictable
eventualities. However, what happened to the market after the sneak attack on
Pearl Harbor on December 7, 1941, might provide a clue. At the time of the
attack, the market was already down roughly 10% from its previous high. On
news of the attack, the Dow fell 8.8% over a two-week period before recovering
in early


January. By November 1942, less than a year later, the Dow had rallied back to
its pre-attack level.

  As far as the post-September 11 stock market is concerned, I think there
will be at least five and perhaps six areas of economic stimulus that will be
very important. They are:

  One, we will see some tax cuts. I am not sure how Congress will work out the
specifics, but there is some bipartisanship and we'll get something.

  Two, there will be more government spending. President Bush is requesting an
economic stimulus package of $75 billion on top of $40 billion in emergency
spending and $15 billion to the airlines. And, we expect there will be more of
that.

  Three, we have lower oil prices, partly because of the attack. The effect is
almost like a tax cut.

  Four, the Fed has cut rates two more times since the attack, and it is
flooding the economy with liquidity. This may be temporary, but it should
help.

  Five, the insurance companies will pay out at least $40 billion. That is not
just for the World Trade Center. It includes life and other property insurance
that will go back to rebuilding the economy.

  Then, there is a sixth stimulus that has nothing to do with the terrorist
attack. It is the huge inventory drop, which I was paying a lot of attention
to prior to September 11. Capacity utilization is also way down, but at some
point, inventory gets so thin that it has to be rebuilt.

  These are all positives for the economy. As for negatives, we may see one
for housing, depending on the direction of prices. Also, consumer confidence
is pretty poor. Consumer confidence is also low at the end of a recession.
That did not bother me before the attack, but there's an additional fear
factor here. If consumers are reluctant to spend--and I am not making a
prediction--there could be some problems.

  I don't know whether or when people will go back to living normally, but
there will be increased spending. But will it be enough to give us a vigorous
recovery? My guess is probably not. However, I think we will come off the
lows.

  There is an enormous shock effect right now. Whatever the gross national
product is for the third and fourth quarters, I believe we will see a positive
first quarter in 2002, but I don't look for it to be huge.

  Prior to the attack, consumers were concerned about the weakening economy.
S&P 500 earnings were down about 22% for the quarter, and the unemployment
rate was up 1% this year to 4.9%. However, the S&P has returned 15.8% in
previous periods when earnings were down versus only 3.8% when earnings were
up 10% or better. In addition, in the nine previous cases when unemployment
rose 1% as it has this year, the S&P was higher a year later in every case by
an average of 24.9%. History shows that once economic weakness is this
widespread and the Fed is cutting rates, stocks soon bottom and head sharply
higher.

  My indicators are bullish. Our monetary model is supported by nine Fed cuts,
T-bills yields down over 50%, long bond yields off over 20%, and a
dramatically steeper yield curve. Our sentiment model is extremely bullish as
well because of the widespread pessimism. The puts/calls ratio, investor
sentiment surveys, and cash levels show that investors have raised cash in
fear of lower stock prices. In previous instances when investors have shown
this level of pessimism, the market has returned over 32% a year.

  In view of the above considerations, we remain bullish and as of this
writing, are about 97% invested.

                                       2



                             PORTFOLIO COMPOSITION

  Our leading industry groups as of September 30 included health care,
financial services, technology, telecommunications, oil and oil services, and
retailing. These groups all appeared on our June 30 listing. During the
quarter, we increased our position in health care, a category that held up
well in a difficult market. Our holdings were trimmed in oil and oil services,
a group that underperformed. Technology lost exposure because of market
weakness.

  Some of our largest individual holdings include Pfizer, Microsoft, General
Electric, Citigroup, Wal-Mart, Johnson & Johnson, Tyco, SBC Communications,
Verizon, and Eli Lilly.

  Eli Lilly is new to our portfolio. Johnson & Johnson, SBC Communications,
and Verizon showed relatively good performance during the quarter. Among the
top holdings listed in our previous quarterly report, we have reduced our
stake in AOL Time Warner, and IBM and Intel underperformed.

             Sincerely,
             /s/ Martin E. Zweig, Ph.D.
