Dear Fellow ZF Shareholder:

I encourage you to take time to read the following manager's report and
commentary for The Zweig Fund for the quarter ended September 30, 2004. In it,
Dr. Martin Zweig, president of Zweig Consulting, sub-adviser to the Fund,
discusses market insights, and portfolio manager, Carlton Neel, reviews the
Fund's composition, including sector allocations and top holdings.

The Zweig Fund's net asset value increased 1.29% for the quarter ended
September 30, 2004, including the $0.020 distribution paid on July 26. During
the same period, the S&P 500 Index declined 1.88%, including dividends.

For the nine months ended September 30, 2004, the Fund's net asset value
increased 3.33%, including the latest distribution. During the same period, the
S&P 500 Index gained 1.50%, including dividends.

The Fund's new annualized 10% fixed cash distribution policy, which was
approved by the board of directors on August 10, went into effect with the
distribution for the quarter ended September 30. As announced, that
distribution was $0.144 payable on October 26, 2004 to holders of record on
October 8, 2004. Including this distribution, the Fund's total payout since
inception is now $18.145.

Finally, worth noting, the Fund's share price increased in the quarter,
serving to narrow the trading discount to 7.77% compared to its net asset value
of $5.79.

As always, we welcome your comments and feedback.

Sincerely,

/s/ Daniel T. Geraci

MARKET OVERVIEW AND OUTLOOK

After rallying in mid-August, all the major indexes finished lower for the
third quarter. The Dow Jones Industrial Average ("the Dow") ended the period
down 3.4%, its biggest quarterly decline since the first quarter of 2003. For
the year the Dow is off 3.6%. The S&P 500 Index slipped 2.3% (excluding
dividends) for the quarter but had a 0.24% gain for the year. Hardest hit was
the NASDAQ Composite Index, which dropped 7.4% for the quarter and was off 5.3%
for the year.

It could be that the biggest single factor responsible for the lackluster
performance was the skyrocketing price of oil which, as of October 26th was
about $54 a barrel, up about 65% for the year and at a 21-year high. That can
make for tough going for the market because it slows down the economy and
worsens the outlook for company profits. Also weighing in are the problems in
Iraq and the uncertainty about the presidential election.

Although some analysts may view these signs as the beginning of a bear
market, we are inclined to think it is a correction in a bull market. While we
believe the market will eventually rebound to its higher levels of earlier this
year or late last year, we are not as confident about the long, long run. But
we aren't worried about predictions and prefer to go with our indicators
instead. As they get better, we'll want to buy more. If they worsen, we'll sell
some.

As widely expected, the Federal Reserve raised its key short-term interest
rate by a quarter-point in September to 1.75%, its third advance in three
months. In its September 21 news release, the Federal Open Market Committee
said that the U.S. economy appears to have regained some traction after
moderating earlier this year and inflation expectations have eased in recent
months. The FOMC also saw upside and downside risks roughly equal for achieving
sustainable growth and price stability for the next

few months and said it anticipates raising rates at a "measured" pace.

Historically, in line with the old Wall Street adage "three steps and a
stumble," which refers to the impact of rate hikes on the stock market, stock
prices have reportedly declined after three successive interest rate hikes by
the Fed. But, if you were to look deeper into this claim, it doesn't work out
quite that easily. Generally, average returns in the market are somewhat flat
after the Fed hikes rates three times.* But nowadays, the Fed doesn't operate
the way it used to. Previously the Fed surprised the market when it cut or
raised rates. Now the Fed tends to telegraph moves. The latest rate hikes were
widely expected and were already factored into the marketplace. Probably a few
more boosts are anticipated as well.

We believe the economy is perhaps a little softer than what the Fed thinks,
in part because oil prices have really been spiking. As for inflationary
expectations, we are uncertain. Perhaps the Fed doesn't think that is the case,
but we believe inflation will edge higher in a year or so but it will not be a
huge move. However, if oil prices were to put a brake on the economy,
inflationary pressures might lessen. Even if oil prices continue to advance,
other prices might decline.

The question of inflation is a factor in how high the Fed will raise
interest rates. Some analysts say the Fed will pause at 2%, others see 2.5% to
3%. We think that the Fed itself may be unsure at this time. Because they don't
have a crystal ball, it is likely they will simply react to prevailing economic
conditions.

Meanwhile, there certainly has been inflation in the federal budget deficit.
The Congressional Budget Office estimated the figure at $422 billion on
September 30, the end of the U.S. Government's fiscal year. It was a drop of
$56 billion from its earlier estimate, but still a record high in dollar terms.
That's not necessarily a problem. We recently ran a study and found that,
historically, the market actually does best when there is a deficit and worse
when there is a surplus.* A surplus is more apt to occur during a business
boom. That's when rates tend to rise and the Fed starts to hike. Eventually,
the market gets extended beyond the fundamentals and a bear market follows.

From our analysis, deficits usually return when there is a recession and a
slower economy reduces tax revenues. We are still trying to climb out of the
recession, which lasted from March 2001 to November 2001. Market consensus is
that we are not in it anymore but it's been a slow recovery. Part of the
deficit is attributable to the tax cuts passed to stimulate the economy, which
generally is bullish for the market. There has also been, of course, the
increased military spending. All in all, we don't have any special concern
about the deficit as long as the economy continues in good shape.

Another deficit in the news is the U.S. trade deficit. The difference
between our exports and imports jumped to $54 billion in August, the highest
gap since hitting a record high of $55 billion in June 2004.* When the trade
deficit gets very large, it tends to put downward pressure on the dollar. The
dollar has been very weak against the Euro, the British pound and the Japanese
yen.* If the dollar weakens further, foreigners would tend to buy more of our
cheaper goods, and we would tend to buy fewer more expensive foreign goods,
thus helping to narrow the deficit. This might be a self-correcting mechanism
of sorts.

While the U.S. economy grew at a slower pace in the second quarter, the drop
was not as steep as previously reported. The Commerce Department said that the
nation's gross domestic product rose at a 3.3% seasonally adjusted rate, faster
than the 2.8% gain earlier estimated. Growth in the previous four quarters
exceeded 4%. In this regard the market got a brief boost when Anthony M.
Santomero, president of the Federal Reserve Bank of Philadelphia (and,
incidentally, a former member of our board of directors), said he expected the
economy to grow by 3.5% to 4%

through 2005. We hope he is right; however, even growth in the 3% range is
pretty decent at this stage of an economic recovery. And, in our view, it would
not be a big worry if the economy dips to 2% as some analysts are predicting
over the next quarter or two. If the economy slows enough and bond yields come
down, it would likely stimulate the housing market. Although we believe that
the economy will not be as strong as it was a year or two ago, it should hold
up pretty well.

As is normal coming out of a recession, the rate of productivity in the
nation's factories declined to a 2.5% annual rate in the second quarter from
3.7% in the first quarter, according to the Labor Department. It was the
slowest growth pace since the fourth quarter of 2002. Our analysis shows that
productivity is always high at the very beginning of a recovery and then slows
down as hiring grows. We have seen increases in employment in recent months but
at a lower rate than in previous recoveries. On the whole, we believe the
current numbers are pretty satisfactory.

Mergers and acquisitions in the U.S. rose 18% to $154 billion in the third
quarter from $131 billion in the year earlier, according to Thomson Financial.
This growth is considered normal a couple of years into a bull market, and
therefore, we don't think that the numbers are excessive yet. We are not seeing
wild takeovers at crazy prices, which would concern us.

We also don't think we are seeing excesses in initial public offerings,
although the rate this year is the highest since the record set in 2000. IPOs
totaled 70 in the third quarter, raising $13.25 billion, according to Thomson
Financial. This compares with 62 that raised $10.1 billion in the second
quarter and 21 that raised $3.8 billion in the third quarter of last year. As
with mergers, it is easier to bring out IPOs during a bull market. We view it
as a warning signal when too many new issues are doubling on the first day and
companies are coming out without earnings or with ridiculous price/earnings
ratios. We don't think we are there yet.

American corporations are increasing their cash holdings at the fastest rate
in 30 years. For the 12-month period ending in March, non-financial companies
carried cash equal to nearly 24% of outstanding debt, according to Moody's
Investment Service. It was the highest cash ratio since 1969. In another
measurement, the total of cash and liquid investments equaled 146% of capital
spending, topping the previous peak in 1962.

Except for some industries such as the airlines, we believe corporate
balance sheets are in pretty good shape on average. Because the recession was
tough, companies have hesitated to spend on capital equipment. Also, they
overspent a lot on technology in the late 1990s and in 2000 and may not be
inclined to spend more.

We think it is a positive that balance sheets are this solid. A skeptic
might say that there are not enough business opportunities for companies to
expand and therefore they are holding onto cash. That might be true to some
extent. However, we feel that the conservative stance by corporations is a
plus. If they start throwing their cash around indiscriminately, that might be
the time to worry in our view. That hasn't happened yet.

While corporations are awash with cash, consumers, whose spending accounts
for two thirds of the gross domestic product (GDP), are falling heavier into
debt, according to the Federal Reserve. Household borrowings totaled $9.7
trillion at the end of the second quarter compared with the nation's GDP of
$11.6 trillion in the same period.

We do not find these figures encouraging. No matter how you measure consumer
leverage, it is way up there, especially relevant to the GDP. It is harder and
harder for consumers to borrow more money because they often are over
leveraged. In our opinion, that is an important reason why the recovery from
the recession has been slower than normal.

The NASDAQ Stock Market reported that short selling on its exchange grew
1.8% for the month through September 15. The New York Stock Exchange also
reported an increase of 1%. These changes were relatively flat, but the volume
on the exchanges near the end of the summer went down. As a result, the short
interest ratio -- the short interest divided by the average daily
volume -- went up on both exchanges. The NASDAQ is particularly high, and, in
fact, hit a record.

We measured the short interest ratio on NASDAQ relative to a longer term
trend to find out how far above or below the trend we are. It turns out we are
far above the trend.* The market has tended to outperform the norm by about
double when the short interest ratio has been this high. Of course it doesn't
always work, but we feel this indicator is in pretty good shape.

So far this year about 430 companies have announced stock buyback programs
totaling about $87 billion, according to Thomson Financial. Meanwhile, insiders
bought $171 million of their own company's shares in August, the heaviest month
in two years. However, they sold nearly $3 billion worth of their company
holdings. As we see them, the buybacks are bullish, and the insider selling is
bearish. As mentioned earlier, companies have extra cash and it does help the
market when they buy their own stock. But insiders have been very heavy on the
sell side for quite some time. They are not always right, of course, but it is
discomforting to us to see so much insider selling.

The pace of earnings growth is decelerating. Profits for the companies in
the S&P 500 Index are estimated to have climbed 14.2% for the third quarter,
off sharply from the 25.3% gain estimated for the second quarter, according to
Thomson First Call. According to our analysis it marks the first time earnings
growth has been below 20% since the second quarter of 2003. Earnings growth
next year is forecast at about 10%, about half of the 19% expected this year.

Again, we believe we are in that stage of the business recovery where it
gets harder and harder to have outsized earnings gains. Gains are easiest early
in the recovery because you are comparing current earnings against very
depressed earnings. But now current earnings are being compared against
improving earnings from a year back. Despite this, however, a 10% gain in
earnings isn't too bad in our opinion.

Despite lower taxes on dividends, dividend yields on the S&P 500 Index came
to 1.6% at the close of the second quarter. It seems that dividend yields are
rather low and the price/earnings ratios are on the high side. We are concerned
about the valuations in the market and do not believe that the market is cheap.

At this writing, our position is slightly more than neutral. The tape action
has been pretty positive. We try to give some weight to the old adage, "don't
fight the tape." Our monetary indicators are about neutral. While it is true
that the Fed has been hiking short rates, the bond markets have been relatively
okay. Our sentiment indicators are also about neutral. Meanwhile, the economy
has been holding up. Because the tape action has been reasonably positive, we
give the bulls a small edge here. With a moderately bullish posture, we in the
vicinity of 75% invested right now.

Conforming to the Fund's goal of seeking reasonable returns while minimizing
risk, our average market exposure for the third quarter was 71% in equities and
16% in bonds. Our average exposure for the first nine months was 71% in
equities and 19% in bonds.

discretionary sectors, both of which appeared in our June 30 report.

Our top individual holdings as of September 30, 2004 included NASDAQ 100
Trust, Dow Chemical, Occidental Petroleum, Sanofi-Synthelabo, PACCAR, Angiotech
Pharmaceuticals, Alcoa, Kerr-McGee, Norfolk Southern and Valero.

NASDAQ 100 Trust and Valero are new positions. During the quarter we added
to our holdings of Dow Chemical and Angiotech. Although Occidental, Sanofi, and
Norfolk Southern are new to this listing, there were no changes in the shares
owned for these companies.

No longer in our top holdings are Georgia Pacific, Deere and Honda, where we
trimmed our positions. Although we added to our positions in Pfizer and there
were no changes to our holdings in Kimberley Clark, Ann Taylor, and Waste
Management, these four companies also are no longer among our top holdings.

NOTES TO SCHEDULE OF INVESTMENTS AND SECURITIES SOLD SHORT

September 30, 2004
(Unaudited)

NOTE 1 -- SIGNIFICANT ACCOUNTING POLICIES

The following is a summary of significant accounting policies consistently
followed by the Fund in the preparation of its Schedules of Investments and
Securities Sold Short. The preparation of Schedules of Investments and
Securities Sold Short requires management to make estimates and assumptions
that affect the reported amounts of assets and liabilities. Actual results
could differ from those estimates.

A. Security Valuation

Equity securities are valued at the official closing price (typically last
sale) on the exchange on which the securities are primarily traded, or if no
closing price is available, at the last bid price.

Debt securities are valued on the basis of broker quotations or valuations
provided by a pricing service, which, in determining value, utilizes
information with respect to recent sales, market transactions in comparable
securities, quotations from dealers, and various relationships between
securities.

Securities for which market quotations are not readily available (of which
there were none at September 30, 2004) and other assets, if any, are valued at
fair value as determined under procedures approved by the Board of Directors of
the Fund.

Short-term investments having a remaining maturity of 60 days or less are
valued at amortized cost, which approximates market.

B. Security Transactions and Related Income

Security transactions are recorded on the trade date. Dividend income is
recorded on the ex-dividend date, or in the case of certain foreign securities,
as soon as the Fund is notified. Interest income is recorded on the accrual
basis. The Fund amortizes premiums and accretes discounts using the effective
interest method.

Realized gains and losses are determined on the identified cost basis.

C. Foreign Currency Translation

Foreign securities and other assets and liabilities are valued using the
foreign currency exchange rate effective at the end of the reporting period.
Cost of investments is translated at the currency exchange rate effective at
the trade date.

D. Forward Currency Contracts

The Fund may enter into forward currency contracts in conjunction with the
planned purchase or sale of foreign denominated securities in order to hedge
the U.S. dollar cost or proceeds. Forward currency contracts involve, to
varying degrees, elements of market risk in excess of the amount recognized

in the Schedules of Investments and Securities Sold Short. Risks arise from the
possible movements in foreign exchange rates or if a counterparty does not
perform under the contract.

A forward currency contract involves an obligation to purchase or sell a
specific currency at a future date, which may be any number of days from the
date of the contract agreed upon by the parties, at a price set at the time of
the contract. These contracts are traded directly between currency traders and
their customers.

E. Foreign Security Country Determination

A combination of the following criteria is used to assign the countries of
risk listed in the Schedules of Investments: country of incorporation, actual
building address, primary exchange on which the security is traded and country
in which the greatest percentage of company revenue is generated.

F. Options

The Fund may write covered options or purchase options contracts for the
purpose of hedging against changes in the market value of the underlying
securities or foreign currencies. As of September 30, 2004, the Fund has no
written options outstanding.

Purchased options are included in the Fund's Schedule of Investments and
Securities Sold Short and are marked to market to reflect the current value of
the options. When a purchased option is exercised, the cost of the security is
adjusted by the amount of the premium paid. The risk associated with purchased
options is limited to the premium paid.

G. Short Sales

A short sale is a transaction in which the Fund sells a security it does not
own in anticipation of a decline in market price. To sell a security short, the
Fund must borrow the security. The Fund's obligation to replace the security
borrowed and sold short will be fully collateralized at all times by the
proceeds from the short sale retained by the broker and by cash and securities
deposited in a segregated account with the Fund's custodian. If the price of
the security sold short increases between the time of the short sale and the
time the Fund replaces the borrowed security, the Fund will realize a loss, and
if the price declines during the period, the Fund will realize a gain. Any
realized gain will be decreased by, and any realized loss increased by, the
amount of transaction costs. Dividends on short sales are recorded as an
expense to the Fund on ex-dividend date. At September 30, 2004 the value of
securities sold short amounted to $14,026,900 against which collateral of
$58,786,104 was held. The collateral includes the deposits with broker for
securities held short and the value of the segregated investments held long, as
shown in the Schedule of Investments and Securities Sold Short. Short selling
used in the management of the Fund may accelerate the velocity of potential
losses if the prices of securities sold short appreciate quickly. Stocks
purchased may decline in value at the same time stocks sold short may
appreciate in value, thereby increasing potential losses.
