                           MARKET REVIEW AND OUTLOOK

   The stock market's performance in the second quarter was nothing to write
home about. The Dow Jones Industrial Average finished off 1.6%. The S&P 500(R)
Index scratched out a mere 1.4% gain while the NASDAQ Composite Index rose
3.1%. All three major markets closed lower for the first half. The Dow was down
3.8%, falling back to its level at the close of 2003. The S&P dipped 0.8% and
the NASDAQ slumped 5.1%.

   As widely expected, the Federal Reserve (the "Fed") raised its short-term
benchmark interest rate by a quarter-point to 3.25%, the ninth consecutive
increase by that amount in a year. Although the chief of the Dallas Fed
previously said that we are in the "eighth inning" of the current tightening
cycle, Fed chairman Alan Greenspan took us into extra innings, with no
indication as to when this particular game will be over.

   We believe that many investors were disappointed when the Fed repeated its
previous assertions that it expects to continue to increase rates at a
"measured pace" and the market closed down sharply after that announcement. In
its economic outlook, the Fed said that, despite




higher energy prices, expansion remains firm and labor conditions continue to
improve gradually. It added that pressures on inflation have stayed elevated
but longer-term expectations remain well contained.

   In our opinion, one problem with the Fed is that it seems to wait too long
and then goes too far. It may do the same this time around. We believe it
should not have driven rates down to 1% at a time when the economy was
improving. Now it may do the reverse by raising rates too high as the economy
is slowing.

   Some analysts point to last year's market surge after the presidential
election and predicted a similar response this year if the Fed stops raising
interest rates. To us, that is not a reasonable assumption. When an election is
over, you know who won and the market can rally. But, we believe that Greenspan
will never ring a bell and announce that he has finished raising rates because
he wants to stay flexible. In our view, he'll leave himself enough of an
opening to do what he thinks is necessary.

   We agree with Greenspan on one issue: his view of the housing boom.
Greenspan said that a nationwide bubble is unlikely but saw signs of "froth" in
some areas, with speculation a possible growing factor. Sales of new homes rose
21% in May and home prices climbed 51% in the five years ended March 31,
according to the Office of Federal Housing Enterprise Oversight.

   To put the situation in perspective, a 51% rise over five years comes out to
about 8.6% a year. Assets gaining 8.6% a year don't seem like a bubble to us.
When the stock market was soaring 25% a year for five years and the NASDAQ was
doing a lot more, people were denying there was a bubble. With housing, we are
getting a fraction of those gains and analysts are talking about a bubble that
may burst.

   As Greenspan suggested, there are certain pockets where there is excessive
speculation in housing. For example, in the city of Miami alone, 62,000 condo
units are either being built or planned. In the previous decade, there were
only about 7,000 condos built in all of Miami. Heavy growth is also taking
place in certain areas of California, New York and Nevada. On balance, the
housing boom is very localized, with a lot of the country not seeing
overspeculation.

   With mortgage rates linked to the 10-year Treasury bond yield, housing has
become very contra-cyclical to most of the rest of the economy. We feel that if
the economy softens and bond yields decline, the housing market will stay
strong; but if the economy strengthens and bond yields rise, the housing market
will weaken. So we are not too concerned about a housing bubble hurting the
stock market.

   We are also not losing much sleep over the trade imbalance. While U.S.
imports and exports set records in April (the last month for which figures are
available), the trade deficit widened 6.3% to $57 billion from $53.6 billion in
March, according to the Commerce Department. Year to date through April, the
gap was 22% higher than for the same period in 2004 and is on track to surpass
last year's record $618 billion.

   Many people seem to worry about the trade deficit unnecessarily. Foreigners
want to give us dollars and are willing to take our dollars in return for goods
that are less expensive. We believe that it really does help the American
consumer to import goods that are cheaper. We may have fewer jobs because of
this, but that is sometimes a trade-off. We are not saying it is good to lose
jobs, but we think protectionism would be worse. We believe the U.S. should try
to be more efficient and produce things better than the rest of the world.

   Speaking of deficits, the Federal government's budget deficit declined
dramatically in May. Reflecting a surge in tax receipts, the May deficit was
$35.29 billion, down from $62.46 billion in the like month a year ago, and the
smallest gap for May since the $27.9 billion in 2001. It is good that the
deficit is narrowing. We have


                                      2




always felt that the economy would benefit from lower taxes and that eventually
the deficit would disappear. While it is counterintuitive, our research has
shown that the stock market does better when there is a federal deficit than
when there is a surplus.

   Continuing to show unexpected strength, the dollar climbed 7% against the
euro and 3.5% against the yen in the second quarter. It was the second straight
quarter of increases and represented the dollar's best showing in over four
years. For the first half of the year, the dollar rose 12% against the euro,
the highest figure since the euro was launched in 1999. We have tested the
dollar against stock market trends but haven't found any consistent
relationship.

   An interesting question to ask is: "Why would the dollar rally when the
trade and budget deficits and housing inflation are so terrible?" We believe
that much of the rest of the world is eager to buy these dollars and hold them.
The U.S. still tends to be a safe haven and foreigners seem to like investing
here, possibly because they feel secure buying our bonds, real estate or stocks.

   The second quarter saw a decline in initial public offerings. Forty-seven
deals were completed, compared to 58 in the like period a year ago, according
to Thomson Financial. The second quarter deals totaled $8.15 billion against
last year's $9.5 billion. These figures seem to indicate that we're not at the
hysteria level we saw in the late 90s when the volume of new issues pointed to
an extremely overheated market. We feel that the current amount of offerings is
reasonable.

   While IPOs were lower, mergers and acquisitions made a strong showing. The
amounts spent on deals spurted 73% in the second quarter against the like
period last year and increased 20% from this year's first quarter, according to
Thomson Financial.

   This level of activity tends to be bullish. It doesn't surprise us because
we believe that corporations are loaded with cash. The debt-equity ratios of
non-financial corporations are way down. The amount of cash held by
corporations relative to their assets is at its highest level for at least the
last 25 years for which we have data. So there seems to be plenty of money
around, and we feel that many companies are ripe for takeover or may seek to
become buyers themselves. We think this situation will continue and is a plus
for the stock market.

   The New York Stock Exchange reported that margin debt at its member firms
fell 2.7% from the end of the first quarter through May. After dropping sharply
after April's big market decline, margin debt rose in May as stock prices
recovered but not enough to offset April's large drop. We believe that this is
a figure to watch. Just like the new issues market, it can get excessive when
there is too much speculation. When margin debt rises quickly, it can be a
warning sign, but we don't think it has done that here.

   American investors seem to be chasing the hottest markets. In May, Americans
invested $5.178 billion in mutual funds that invest primarily in domestic
stocks, more than double the $2.260 billion in April, according to the
Investment Company Institute. However Americans poured much more money into
world stock funds during these two months, with $6.011 billion invested in May
and $6.372 billion in April.

   We don't think it is a great idea for people to chase what is hot.
Historically, foreigners tend to be wrong when they plunge into our markets,
and U.S. investors tend to do just as bad in foreign markets. So these numbers
may not be a great sign for foreign markets where there may be too much
exuberance. As far as our domestic markets are concerned, these mutual fund
numbers appear positive.

   We also like the figures on stock buybacks by companies in the S&P 500
Index. These buybacks were a major factor in building company holdings of cash
and cash- equivalent securities in


                                      3




the first quarter, according to Thomson Financial. Their holdings grew 10.1% to
a record $766 billion. Buybacks showed the biggest gain as a share of total
cash, climbing to 8% in the first quarter against 3.1% in the like 2004 period.
The stock buyback total nearly tripled to $61 billion. As indicated earlier,
this excessive cash can be put to good use. Some companies will continue to use
it for buying their own stock, buying other companies or paying out higher
dividends. We feel that all of the above are bullish for the market.

   Stock market advisors became more optimistic as the market rallied recently.
A recent survey by Investors Intelligence of advisors found 55.1% bullish and
only 19.1% bearish. The bullish figure is the highest since March of this year,
while the bearish total is the lowest since July of 2004. We don't think these
figures are excessive yet. We believe it would have to go to a much greater
extreme to indicate a market top.

   S&P 500-listed companies are now trading at about 19.6 times earnings over
the past 12 months. Historically, the rate has been about 15 times earnings. At
these figures, we don't believe the market is excessively valued, but we don't
think it is cheap either.

   The same mixed picture holds true for the economy in general. It has
definitely slowed but we don't think we are headed into a recession nor do we
see a boom. Actually, it looks fairly good to us because it is not strong
enough to make inflation a worry -- but it is not weak either.

   At this writing, virtually all of our indicators are smack in the neutral
range. When this happens, the market has generally risen at a reasonable rate.
Historically, it has gone up about 10% a year. We might cut a few points off
that number because we had above normal gains in the 1980s and 90s. So with
that in mind, perhaps we'll adjust the projected gain to 7% or 8%. We'll take
it.

   Overall, we think the market is okay. It has six months to consolidate the
gains it made in the fourth quarter of 2004. Our current investment posture is
moderately bullish and we are about 80% invested in common stocks.

              Sincerely,

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

                             PORTFOLIO COMPOSITION

   Our leading stock market sectors on June 30, 2005, included financials,
health care, consumer staples, information technology, and industrials.
Although there were changes in allocation amounts, all of these sectors were
listed in our previous quarterly report. During the second quarter, we added to
our positions in information technology and consumer discretionary and trimmed
our holdings in industrials and telecommunication services.

   As of June 30, 2005, our top individual positions included Allstate,
Burlington Resources, Continental Airlines, Costco Wholesale Corp.,
Halliburton, Home Depot, NASDAQ 100 Trust, UnitedHealthgroup, Valero Energy,
and Wells Fargo. During the quarter, we added to our positions in Costco, Home
Depot, NASDAQ 100 Trust, and Valero. There was no change in the number of
shares held in Allstate and Wells Fargo.

   Although our holdings were unchanged in Georgia Pacific, Goldman Sachs,
Kimberly Clark, and Morgan Stanley, these companies are no longer in our list
of top positions. Also out of this listing are Merck, where we reduced our
holdings, and United Defense, where we sold out.

              Sincerely,

                         NOTES TO FINANCIAL STATEMENTS

                                 June 30, 2005
                                  (Unaudited)

NOTE 1 -- ORGANIZATION

   The Zweig Fund, Inc. (the "Fund") is a closed-end, diversified management
investment company registered under the Investment Company Act of 1940 (the
"Act"). The Fund was incorporated under the laws of the State of Maryland on
June 30, 1986. The Fund's objective is to increase capital primarily with
investment in equity securities, consistent with capital preservation and
reduction of risk.

NOTE 2 -- SIGNIFICANT ACCOUNTING POLICIES

   The following is a summary of significant accounting policies consistently
followed by the Fund in the preparation of its financial statements. The
preparation of financial statements in conformity with accounting principals
generally accepted in the United States of America requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities, contingent assets and liabilities at the date of the financial
statements and the reported amount of increases and decreases in net assets
from operations during the reporting period. 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.

                                      16





  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. Income Taxes:

   It is the policy of the Fund to comply with the requirements of the Internal
Revenue Code and to distribute substantially all of its taxable income to its
shareholders. Therefore, no provision for federal income taxes or excise taxes
has been made.

   The Fund may be subject to foreign taxes on income, gains on investments or
currency repatriation, a portion of which may be recoverable. The Fund will
accrue such taxes and recoveries as applicable based upon current
interpretations of the tax rules and regulations that exist in the markets in
which they invest.

  D. Dividends and Distributions to Shareholders:

   Distributions are declared and recorded by the Fund on the ex-dividend date.
Income and capital gain distributions are determined in accordance with income
tax regulations which may differ from accounting principles generally accepted
in the United States of America. These differences may include the treatment of
non-taxable dividends, market premium and discount, non-deductible expenses,
expiring capital loss carryovers, foreign currency gain or loss, operating
losses and losses deferred due to wash sales. Permanent book and tax basis
differences relating to shareholder distributions will result in
reclassifications to capital paid in on shares of beneficial interest.

   The Fund has $174,545,775 of capital loss carryovers, $10,860,573 expiring
in 2009, $136,883,040 expiring in 2010 and $26,802,162 expiring in 2011 which
may be used to offset future capital gains. The Fund may not realize the
benefit of these losses to the extent it does not realize gains on investments
prior to the expiration of the capital loss carryovers. In addition, under
certain conditions, the Fund may lose the benefit of these losses to the extent
that distributions to shareholders exceed required distribution amounts as
defined under the Internal Revenue Code. Shareholders may also pay additional
taxes on these excess distributions.

  E. 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. The gain or loss resulting from a change in currency exchange
rates between the trade and settlement date of a portfolio transaction is
treated as a gain or loss on foreign currency. Likewise, the gain or loss
resulting from a change in currency exchange rates between the date income is
accrued and paid, is treated as a gain or loss on foreign currency. The Fund
does not isolate that portion of the results of operations arising from changes
in exchange rates and that portion arising from changes in the market prices of
securities.

                                      17





  F. 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 Statement of Assets and Liabilities. Risks arise from possible movements in
foreign exchange rates or if the 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. The contract is marked-to-market daily and the change in
market value is recorded by the Fund as unrealized gain or loss. When the
contract is closed or offset with the same counterparty, the Fund records a
realized gain or loss equal to the change in the value of the contract when it
was opened and the value at the time it was closed or offset.

  G. Foreign Security Country Determination:

   A combination of the following criteria is used to assign the countries of
risk listed in the schedule of investments and securities sold short: 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.

  H. 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.

   The Fund will realize a gain or loss upon the expiration or closing of the
option transaction. Gains and losses on written options are reported separately
in the Statement of Operations. When a written option is exercised, the
proceeds on sales or amounts paid are adjusted by the amount of premium
received. Options written are reported as a liability in the Statement of
Assets and Liabilities and subsequently marked-to-market to reflect the current
value of the option. The risk associated with written options is that the
change in value of options contracts may not correspond to the change in value
of the hedged instruments. In addition, losses may arise from changes in the
value of the underlying instruments, or if a liquid secondary market does not
exist for the contracts.

   The Fund may purchase options, which are included in the Fund's Schedule of
Investments and Securities Sold Short and subsequently marked-to-market to
reflect the current value of the option.

   When a purchased option is exercised, the cost of the security is adjusted
by the amount of premium paid. The risk associated with purchased options is
limited to the premium paid.

   Transactions in written options for the period ended June 30, 2005 were as
follows:

  I. 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, and any realized loss increased, by the amount
of transaction costs. On ex-dividend date, dividends on short sales are
recorded as an expense to the Fund. At June 30, 2005, the value of securities
sold short amounted to $19,619,700 against which collateral of $40,213,930 was
held. The collateral includes the deposits with the 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.

  J. 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 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.

Fund.

   d) Payment by Affiliate: The Adviser made a voluntary payment on August 25,
2005 in the amount of $131,874 to fully offset the net gains and losses

NOTE 5 -- CAPITAL STOCK AND REINVESTMENT PLAN

   At June 30, 2005, the Fund had one class of common stock, par value $.10 per
share, of which 100,000,000 shares are authorized and 73,233,013 shares are
outstanding.

   Registered shareholders may elect to have all distributions paid by check
mailed directly to the shareholder by EquiServe as dividend paying agent.
Pursuant to the Automatic Reinvestment and Cash Purchase Plan (the "Plan"),
shareholders not making such election will have all such amounts automatically
reinvested by EquiServe, as the Plan agent, in whole or fractional shares of
the Fund, as the case may be. During the six-months ended June 30, 2005, and
the year ended December 31, 2004, there were no shares issued pursuant to the
Plan.

NOTE 6 -- 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,

                                      20




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.

(1)Shares were sold at a 5% discount from the average market price.
(2)Closing Price -- New York Stock Exchange.
(3)Total investment return is calculated assuming a purchase of common stock on
   the opening of the first business day and a sale on the closing of the last
   business day of each period reported. Dividends and distributions, if any,
   are assumed for the purchase of this calculation, to be reinvested at prices
   obtained under the Fund's Automatic Reinvestment and Cash Purchase Plan.
   Generally, total investment return based on net asset value will be higher
   than total investment return based on market value in periods where there is
   an increase in the discount or a decrease in the premium of the market value
   to the net assets from the beginning to the end of such years. Conversely,
   total investment return based on net asset value will be lower than total
   investment return based on market value in periods where there is a decrease
   in the discount or an increase in the premium of the market value to the net
   asset value from the beginning to the end of such periods.

(6)Not annualized.
(7)The net realized and unrealized gains (losses) includes a voluntary payment
   made by the Adviser to fully offset the net gains and losses associated with
   a violation of investment restrictions. If this payment was not included,
   the per share impact would be less than $0.01.

At a Board of Trustees meeting held May 16, 2005, the Trustees approved a Policy
for the Consideration of Trustee Nominees as follows:

                                  PHOENIX FUNDS

                Policy for the Consideration of Trustee Nominees

        The following Policy for the Consideration of Trustee Nominees (the
"Policy") shall be followed by the Governance and Nominating Committee (the
"Committee") of the Phoenix Funds (the "Trust") in filling vacancies on the
Board of Trustees or when Trustees are to be nominated for election by
shareholders.

Minimum Nominee Qualifications

1.      With respect to nominations for Trustees who are not interested persons
        of the Trust as defined by Section 2(a)(19) of the Investment Company
        Act of 1940 (the "1940 Act") ("Disinterested Trustees"), nominees shall
        be independent of the Trust's investment advisers and other principal
        service providers. The Committee shall also consider the effect of any
        relationship beyond those delineated in the 1940 Act that might impair
        independence, such as business, financial or family relationships with
        the investment adviser or its affiliates.

2.      Disinterested Trustee nominees must qualify for service on the Trust's
        Audit Committees.

3.      With respect to all Trustees, nominees must qualify under all applicable
        laws and regulations.

4.      The proposed nominee may not be within five years of the Trust's
        retirement age for Trustees.

5.      The Committees may also consider such other factors as they may
        determine to be relevant.

Other Qualifications

1.      With respect to all proposed nominees, the Committee shall consider
        whether the proposed nominee serves on boards of or is otherwise
        affiliated with competing financial service organizations or their
        related fund complexes or companies in which the Trust may invest.

2.      The Committee shall consider whether the proposed nominee is able to and
        intends to commit the time necessary for the performance of Trustee
        duties.




3.      The Committee shall consider the integrity and character of the proposed
        nominee, and the proposed nominee's compatibility with the current
        Trustees.

4.      The Committee may require an interview with the proposed nominee.

Nominees Recommended by Shareholders

1.      The Committee shall consider nominations for openings on the Board of
        Trustees from shareholders who have individually held for at least one
        full year five percent of the shares of a series of the Trust.

2.      The Committee shall give candidates recommended by shareholders the same
        consideration as any other candidate.

3.      Shareholder recommendations should be sent to the attention of the
        Committee in care of the Trust's Secretary and should include
        biographical information, including business experience for the past ten
        years and a description of the qualifications of the proposed nominee,
        along with a statement from the proposed nominee that he or she is
        willing to serve and meets the requirements to be a Disinterested
        Trustee, if applicable.

Process for Identifying and Evaluating Trustee Nominees
