31, 2007 was $0.144, payable on April 26, 2007 to shareholders of record on

                           MARKET REVIEW AND OUTLOOK

   With a roller-coaster market climbing and falling at a dizzying pace, the
first quarter of 2007 was not one for the faint-hearted. In late February, the
Dow Jones Industrial Average/SM/ (the "Dow") plummeted 3.3%, or 415.3
points -- the biggest one-day drop since March 2003. The sharp decline
represented a one-day panic, based on fears of the possible consequences of the
bursting of the sub prime mortgage loan bubble. By fits and starts, the Dow
clawed its way back to close the quarter down only 0.9%, or 108.80 points, at
12,354.35. This marked the first quarterly decline for the Dow since 2005.

   The other major markets showed little change for the quarter, with the
NASDAQ Composite Index ending up 0.3%, or 6.3 points, at 2,421.64, and the S&P
500 Index gaining 0.2% (not including reinvested dividends) or 2.56 points, to
close at 1,431.

   Conforming to expectations, the Federal Reserve ("the Fed") left its
short-term interest rate at 5.25%, unchanged for six meetings in a row after
boosting it 17 consecutive times since 2004. However, for the first time since
it began to raise rates nearly three years ago, the Fed omitted a reference to
"additional firming" or higher rates. In a statement, the Fed said the economy
seems likely to expand at a moderate pace over coming quarters, despite recent
mixed indicators and the ongoing adjustments in the housing sector.

   The Fed noted that while recent readings on core inflation have been
elevated, inflationary pressures seem likely to moderate over time. However, it
expressed concern about the risk that these pressures may fail to moderate,
adding, "Future policy adjustments will depend on the evolution of the outlook
for both inflation




and economic growth." Responding to the Fed's comments, the markets initially
surged ahead. Following these comments, however, the Fed became slightly more
hawkish, warning about the need to protect against inflation. In our view,
there might be enough of a slowdown in the fall to stimulate a cut in the
short-term interest rate.

   Wall Street is keeping a wary eye on the weakening of the housing market,
where sub prime mortgage loans made during the peak of the boom are leading to
a record number of homes being foreclosed. The Mortgage Brokers Association
reported that about 0.54% of all home loans entered foreclosure in the fourth
quarter, the highest ever in the 37-year history of the survey. Confirming the
softness in the housing market, the Commerce Department reported that new
building permits dropped 2.5% in February, the twelfth decline in the last 13
months.

   It is obvious that there is weakness in the housing market and that spells
potential trouble for homebuilding stocks and some vendors. It might also knock
a point or two off the gross domestic product (GDP). If it leads to an interest
rate cut by the Fed, that would actually help the stock market. Consequently,
while the housing situation is not good for homebuilders, we see it as somewhat
positive for the stock market as a whole.

   Including sub prime mortgages, total debt in the U.S. has soared to $44
trillion or 331% of GDP, about twice the level of 30 years ago, according to
Ned Davis Research. It has not been nearly as high since the depression, when
it rose above 250%. We don't consider the mountain of debt a particular
concern. It has been high for years relative to the GDP. The economy just rolls
along with more debt than it had in the past. A lot of the debt comes from
credit cards, which did not exist years ago. That debt just reverts to a slower
method of payment. The debt that bothers us results from people refinancing
their homes and spending the money recklessly, a sure sign of trouble ahead.

   Reflecting the slumping housing market and other signs of a cooling economy,
the Commerce Department reduced its previous forecast for GDP growth in the
fourth quarter from 3.5% to 2.2%. Although slightly above the 2% figure for the
third quarter, it was the third consecutive quarter of lethargic growth.
Commenting on these figures, Fed chairman Ben S. Bernanke said it bolstered the
Fed's view that the economy was on a path to mildly slower growth as well as a
slight decline in inflationary pressures. The Fed forecast that the economy
will expand by 2.5% to 3% this year against 3% last year. It expects employment
to remain below 5%. These figures seem reasonable to us.

   A further indication of a lagging economy was an early April report from the
Institute of Supply Management that its index of manufacturing activity dipped
to 50.9 in March from 52.3 in February. While a number above 50 represents
expansion, there was little in the report pointing to a significant recovery in
the near future.

   There was also little to cheer about in the Commerce Department's report
that demand for durable goods gained 2.5% in February. This is weaker than the
3.5% forecast and followed a whopping 9.3% drop in January, which sparked the
huge late-February market drop.

   Two reports from the Conference Board, an industry research group, also were
not particularly encouraging. The agency reported that its consumer confidence
index slipped to 107.2 in March, from the revised 111.2 in February. The March
reading was the lowest since November 2006, when it fell to 105.3. Earlier, the
board reported that its composite index of leading indicators, which projects
economic changes in the next six to nine months, declined 0.5% in February


                                      2




from a revised 0.3% dip in January. The February drop was the greatest since
February 2006.

   On a more optimistic note, the Commerce Department reported that personal
income and consumer spending each gained 0.6% in February. Despite a decline in
new housing, non-residential state and local projects increased construction
spending that month by 0.3% -- and in early April, the Labor Department
reported that 180,000 new non-farm jobs were created in March, with the
unemployment rate dipping to a four-month low of 4.4%.

   Every report was greeted with intense speculation about how it would affect
the Fed's decision on interest rates, and the markets reacted accordingly. As
we see it, the economy is all right, aside from the cooling of the housing
market. We like the current market and believe it will be relatively stable
this year.

   Despite the volatile stock market and the sobering economic reports, mergers
and acquisitions hit a new record high. The volume of U.S. deals soared 32% in
the first quarter from a year ago, to $439 billion, according to Thomson
Financial. Worldwide, the first quarter surged 27% to $1.1 trillion. The
expansion in mergers and acquisitions is one reason we like this market.

   There is a tremendous amount of money out there and acquisitions have been
rampant. Some recent deals have hit records, with prices of up to $40 billion.
While we previously mentioned the large amount of debt, that does not apply to
corporations, where debt is down and cash is up. As we have pointed out in
previous reports, companies loaded with cash have several alternatives: One,
they can invest in plant and equipment, which they have been slow to do, and
that would be bullish. Two, they can increase their dividends, which is
bullish. Three, they can buy back their stock, which is bullish. Four, they can
buy another company, which is bullish -- or five, they can hold their cash,
making themselves a takeover target, which is also bullish. While at some point
these takeovers can go over the top, we don't think we have hit that point yet.

   Reflecting heavy share buybacks and the buyout bids, the supply of stock has
been shrinking, which is another market plus. The Fed reported that a net $548
billion of stock was removed from the market last year. This marked a record
high, topping the previous peak of $295 billion in 2005. In 2006, the companies
in the S&P 500 alone bought back $432 billion of their own shares.

   There was also no sign of a slowdown in initial public offerings (IPOs). The
first quarter of 2007 saw 48 IPOs with a value totaling $9.8 billion, slightly
above the $9.7 billion in the first three months of last year, according to
Dealogic. While the IPOs do take some money out of the market, we are not
seeing the high level of low-quality offerings that occurred in the 1990s. We
are not at a critical stage in this area yet.

   Following a record of 14 consecutive quarters of double-digit increases,
analysts expect the companies in the S&P 500 to show a gain of only 3.3% in
operating earnings for the first quarter of 2007, according to Thomson
Financial. Earlier, analysts had forecast an 8.7% rise for the quarter. The
3.3% figure would be the smallest quarterly increase since 2002. Thomson's own
projection for the quarter is 6.7% growth, more than double the predictions.

   It does seem that earnings are trending lower. That goes along with the
slowing economy. However, some studies indicate that the market has actually
had mixed results when earnings are declining. While these figures are not
necessarily bullish, they are not necessarily bearish, either.

   Indicating the market's turbulence, margin debt and short selling each
reached new heights


                                      3




during the fourth quarter of 2006. After climbing 24.2% last year, margin debt
on the New York Stock Exchange set successive records in January and February,
gaining 7.4% for the first two months of 2007. Meanwhile, short selling for the
month ended March 15 rose 9.5% from mid-February to a record high. Margin debt
tends to rise during a bull market and we have had a bull market for several
years. While there is some risk in high levels of margin debt, we don't believe
the current figure indicates a problem. As for short selling, that is extremely
bullish. It means that most people are pessimistic about the market and that is
usually a plus. Also, it means that the short shares have to be bought back at
some point, which boosts underlying demand.

   At the end of the first quarter, companies in the S&P 500 were trading at
15.2 times operating earnings, according to Datastream. This figure is in line
with the long-term average. It compares with 18.2 times earnings both at the
year end and on March 31, 2006. These valuations look about normal to us. We
don't think the market is cheap, but we don't believe it is expensive, either.

   Market advisors at the end of the quarter were less optimistic than at the
start of the year, but bulls were still nearly double the number of bears.
Investors Intelligence reported 48.4% bulls and 27.5% bears on March 31. This
compares with 56.5% bulls and 19.6% bears at the year end and 46.7% bulls and
28.2% bears on March 31, 2006. As with valuations, these figures look neutral
to us. We normally have more bulls than bears. These numbers are not bullish,
and we do not believe they point to an overheated market.

   At this writing, our sentiment indicators are very positive. That sell-off
in late winter really shook up investors, and a fair amount of pessimism
prevails. Our monetary indicators are neutral, but have backed up a bit
recently. The interest rate picture is relatively neutral, but the tape itself
is pretty positive. The breadth of the market has been very good, with a lot of
stocks hitting new highs. With all the aforementioned cash companies are
holding onto, the market appears to be in pretty good shape. Consequently, our
investment posture is bullish, and we are about 90% invested.

              Sincerely,

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

                       NOTES TO SCHEDULES OF INVESTMENTS

NOTE 1 -- SIGNIFICANT ACCOUNTING POLICIES

   The following is a summary of significant accounting policies consistently
followed by the Zweig Fund, Inc. (the "Fund") in the preparation of the
Schedule of Investments. The preparation of the Schedules of Investments in
conformity with accounting principles generally accepted in the United States
of America requires management to make estimates and assumptions that affect
the reported amounts of assets and liabilities, and disclosure of contingent
assets and liabilities at the date of the Schedules of Investments. 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 utilizes information with respect to
recent sales, market transactions in comparable securities, quotations from
dealers, and various relationships between securities in determining value.

   As required, some securities and other assets may be valued at fair value as
determined in good faith by or under the direction of the Directors.

   Certain foreign common stocks may be fair valued in cases where closing
prices are not readily available or are deemed not reflective of readily
available market prices. For example, significant events (such as movement in
the U.S. securities market, or other regional and local developments) may occur
between the time that foreign markets close (where the security is principally
traded) and the time that the Fund calculates its net asset value (generally,
the close of the NYSE) that may impact the value of securities traded in these
foreign markets. In these cases, information from an external vendor may be
utilized to adjust closing market prices of certain foreign common stocks to
reflect their fair value. Because the frequency of significant events is not
predictable, fair valuation of certain foreign common stocks may occur on a
frequent basis.

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

   In September 2006, Statement of Financial Accounting Standards No. 157,
"Fair Value Measurements" ("SFAS 157"), was issued and is effective for fiscal
years beginning after November 15, 2007. SFAS 157 defines fair value,
establishes a framework for measuring fair value and expands disclosures about

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. Foreign Security Country Determination:

   A combination of the following criteria is used to assign the countries of
risk listed in the Schedule 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.

E. Security Lending:

   The Fund may loan securities to qualified brokers through an agreement with
State Street Bank and Trust (the "Custodian"). Under the terms of the
agreement, the Fund receives collateral with a market value not less than 102%
for domestic securities and 105% for foreign securities of the market value of
loaned securities. Collateral may consist of cash, securities issued or
guaranteed by the U.S. Government or its agencies and the sovereign debt of
foreign countries. Cash collateral is invested in a short-term money market
fund. Dividends earned on the collateral and premiums paid by the borrower are
recorded as income by the Fund net of fees and rebates charged by the Custodian
for its services in connection with this securities lending program. Lending
portfolio securities involves a risk of delay in the recovery of the loaned
securities or in the foreclosure on collateral.

NOTE 2 -- CREDIT RISK AND ASSET CONCENTRATIONS

   In countries with limited or developing markets, investments may present
greater risks than in more developed markets and the prices of such investments
may be volatile. The consequences of political, social or economic changes in
these markets may have disruptive effects on the market prices of these
investments and the income they generate, as well as the Fund's ability to
repatriate such amounts.

   The Fund may invest a high percentage of its assets in specific sectors of
the market in its pursuit of a greater investment return. Fluctuations in these
sectors of concentration may have a greater impact on the Fund, positive or
negative, than if the Fund did not concentrate its investments in such sectors.

NOTE 3 -- INDEMNIFICATIONS

   Under the Fund's organizational documents, its directors and officers are
indemnified against certain liabilities arising out of the performance of their
duties to the Fund. In addition, the Fund enters

                                      13




into contracts that contain a variety of indemnifications. The Fund's maximum
exposure under these arrangements is unknown. However, the Fund has not had
prior claims or losses pursuant to these contracts and expects the risk of loss
to be remote.

NOTE 4 -- SUBSEQUENT EVENT

   On May 10, 2007, the Fund announced that its Board of Directors approved the
filing of a registration statement with the Securities and Exchange Commission
relating to the offering of additional shares of its Common Stock in connection
with a contemplated Rights Offering. The Fund will determine and announce the
definitive terms of the Rights Offering at a later date. The preliminary
registration statement relating to these rights was filed with the Securities
and Exchange Commission on May 14, 2007. These securities may not be sold, nor
may offers to buy be accepted prior to the time the registration statement
becomes effective. This communication shall not constitute an offer to sell or
the solicitation of an offer to buy nor shall there be any sale of these
securities in any State in which such offer, solicitation or sale would be
unlawful prior to registration or qualification under the securities laws of
any such State, or an exemption there from.
