 (a) Returns  represent past  performance  and do not guarantee  future results.
     Total returns and average annual returns reflect changes in share price and
     reinvestment of dividends and are net of expenses.  Investment  returns and
     the  principal  value of an  investment  will  fluctuate.  When  shares are
     redeemed,  they may be worth more or less than their original cost. The S&P
     500 Index and the Russell 1000 Growth  Index are  unmanaged  indicators  of
     stock market performance.  Dividends are considered reinvested. Performance
     for periods less than one year is not annualized.  Current  performance may
     be  lower  or  higher   than  the   performance   data   presented.   Visit
     www.gabelli.com   for  performance   information  as  of  the  most  recent
     month-end.  Investors should consider the investment objectives,  risks and
     charges and expenses of the Fund before investing.  The prospectus contains
     more complete  information  about this and other matters and should be read
     carefully before investing. The Class AAA Shares' net asset values are used
     to calculate  performance  for the periods prior to the issuance of Class A
     Shares,  Class B Shares and Class C Shares on December 31, 2003. The actual
     performance for the Class B and Class C Shares would have been lower due to
     the additional expenses associated with these classes of shares.
 (b) Performance is calculated  from  inception of Class AAA Shares on April 10,
     1987.
 (c) There is no data  available for the  Russell  1000  Growth  Index  prior to
     August 31, 1992.
 (d) Includes the effect of the maximum  5.75% sales charge at the  beginning of
     the period.
 (e) Includes the effect of the applicable  contingent  deferred sales charge at
     the end of the period shown for Class B and Class C Shares, respectively.

THE GABELLI GROWTH FUND
NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
- --------------------------------------------------------------------------------
1.  ORGANIZATION.  The Gabelli Growth Fund (the "Fund") was organized on October
24, 1986 as a Massachusetts business trust. The Fund is a diversified,  open-end
management  investment  company  registered under the Investment  Company Act of
1940,  as amended  (the "1940  Act").  The Fund's  primary  objective is capital
appreciation. The Fund commenced investment operations on April 10, 1987.

2. SIGNIFICANT  ACCOUNTING POLICIES.  The preparation of financial statements in
accordance  with  U.S.  generally  accepted   accounting   principles   requires
management to make estimates and  assumptions  that affect the reported  amounts
and  disclosures in the financial  statements.  Actual results could differ from
those estimates.  The following is a summary of significant  accounting policies
followed by the Fund in the preparation of its financial statements.

SECURITY  VALUATION.  Portfolio  securities  listed or  traded  on a  nationally
recognized securities exchange or traded in the U.S. over-the-counter market for
which market quotations are readily available are valued at the last quoted sale
price or a market's  official  closing  price as of the close of business on the
day the  securities  are being  valued.  If there  were no sales  that day,  the
security is valued at the  average of the  closing  bid and asked  prices or, if
there were no asked  prices  quoted on that day,  then the security is valued at
the closing bid price on that day. If no bid or asked  prices are quoted on such
day,  the  security is valued at the most  recently  available  price or, if the
Board of Trustees (the "Board") so determines, by such other method as the Board
shall  determine  in good faith,  to reflect its fair  market  value.  Portfolio
securities  traded on more than one national  securities  exchange or market are
valued according to the broadest and most  representative  market, as determined
by Gabelli Funds, LLC (the "Adviser").

Portfolio securities primarily traded on foreign markets are generally valued at
the preceding closing values of such securities on their respective exchanges or
if after the close,  market  conditions  change  significantly,  certain foreign
securities may be fair valued  pursuant to procedures  established by the Board.
Debt  instruments  that are not credit impaired with remaining  maturities of 60
days or less are valued at amortized cost, unless the Board determines such does
not reflect the securities'  fair value, in which case these  securities will be
valued at their fair value as determined by the Board. Debt instruments having a
maturity greater than 60 days for which market  quotations are readily available
are valued at the latest  average of the bid and asked prices.  If there were no
asked  prices  quoted on such day,  the security is valued using the closing bid
price.  Futures contracts are valued at the official closing settlement price of
the exchange or board of trade on which the applicable contract is traded.

Securities and assets for which market  quotations are not readily available are
valued  at their  fair  value  as  determined  in good  faith  under  procedures
established by and under the general  supervision  of the Board.  Fair valuation
methodologies  and procedures may include,  but are not limited to: analysis and
review of available  financial and non-financial  information about the company;
comparisons  to the  valuation  and changes in valuation of similar  securities,
including a comparison of foreign securities to the equivalent U.S. dollar value
ADR  securities at the close of the U.S.  exchange;  and evaluation of any other
information that could be indicative of the value of the security.

SECURITIES  TRANSACTIONS  AND INVESTMENT  INCOME.  Securities  transactions  are
accounted  for on the  trade  date  with  realized  gain or loss on  investments
determined  by using the  identified  cost method.  Interest  income  (including
amortization  of premium  and  accretion  of  discount)  is  recorded as earned.
Dividend income is recorded on the ex-dividend date.


                                        6



THE GABELLI GROWTH FUND
NOTES TO FINANCIAL STATEMENTS (CONTINUED) (UNAUDITED)
- --------------------------------------------------------------------------------
DIVIDENDS AND  DISTRIBUTIONS  TO  SHAREHOLDERS.  Dividends and  distributions to
shareholders are recorded on the ex-dividend  date. Income and long-term capital
gain  distributions  are  determined  in  accordance  with  Federal  income  tax
regulations,  which may differ from accounting  principles generally accepted in
the United States.  These differences are primarily due to differing  treatments
of income and gains on various  investment  securities held by the Fund,  timing
differences and differing characterization of distributions made by the Fund.

For the year ended  December 31, 2003,  reclassifications  were made to decrease
accumulated net investment loss by $10,245,651, with an offsetting adjustment to
additional paid-in capital. No distributions were made in 2003.

EXPENSES. Certain administrative expenses are common to, and allocated among the
Classes of Shares.  Such allocations are made on the basis of average net assets
or other criteria  directly  affecting the expenses as determined by the Adviser
pursuant to procedures established by the Board.

PROVISION  FOR  INCOME  TAXES.  The Fund  intends  to  continue  to qualify as a
regulated  investment company under Subchapter M of the Internal Revenue Code of
1986,  as  amended  (the  "Code").  It is the Fund's  policy to comply  with the
requirements  of the Code  applicable to regulated  investment  companies and to
distribute  substantially  all of its net investment  company taxable income and
net capital gains. Therefore, no provision for Federal income taxes is required.

As of December 31, 2003, the components of  accumulated  earnings/(losses)  on a
tax basis were as follows:

        Accumulated capital loss carryforward .......  $(1,162,162,476)
        Net unrealized appreciation .................       77,189,063
                                                       ---------------
        Total accumulated loss ......................  $(1,084,973,413)
                                                       ===============

The  difference  between  book basis and tax basis  unrealized  appreciation  is
attributable primarily to the tax deferral of losses on wash sales.

The Fund has a net capital loss  carryforward for Federal income tax purposes at
December 31, 2003 of $1,162,162,476. This capital loss carryforward is available
to reduce future distributions of net capital gains to shareholders. $68,961,980
of the loss  carryforward is available  through 2009;  $743,150,002 is available
through 2010; and $350,050,494 is available through 2011.

3.  INVESTMENT  ADVISORY  AGREEMENT.  The Fund has  entered  into an  investment
advisory  agreement (the "Advisory  Agreement")  with the Adviser which provides
that the Fund will pay the Adviser a fee,  computed  daily and paid monthly,  at
the annual rate of 1.00% of the value of the Fund's average daily net assets. In
accordance  with the  Advisory  Agreement,  the  Adviser  provides a  continuous
investment program for the Fund's portfolio,  oversees the administration of all
aspects of the Fund's  business  and  affairs and pays the  compensation  of all
Officers and Trustees of the Fund who are its affiliates.

4.  DISTRIBUTION  PLAN.  The Fund's Board has adopted a  distribution  plan (the
"Plan")  for each class of shares  pursuant  to Rule  12b-1  under the 1940 Act.
Gabelli & Company,  Inc.  ("Gabelli  & Company"), an  affiliate  of the Adviser,
serves as distributor  of the Fund. Under the Class AAA, A, B and C Share Plans,
payments are  authorized  to Gabelli & Company at annual rates of 0.25%,  0.25%,
1.00% and 1.00%, respectively, of the average daily net assets of those Classes,
the annual limitations under each Plan. Such payments are accrued daily and paid
monthly.

5.  PORTFOLIO  SECURITIES.  Purchases and sales of securities for the six months
ended June 30, 2004, other than short term securities,  aggregated  $236,114,492
and $499,113,927, respectively.

NOTES TO FINANCIAL STATEMENTS (CONTINUED) (UNAUDITED)
- --------------------------------------------------------------------------------
6.  TRANSACTIONS  WITH  AFFILIATES.  During the six months  ended June 30, 2004,
Gabelli & Company received $131 from investors  representing  commissions (sales
charges and underwriting fees) on sales and redemptions of Fund shares.

The cost of  calculating  the Fund's net asset value per share is a Fund expense
pursuant to the Advisory  Agreement.  During the six months ended June 30, 2004,
the Fund reimbursed the Adviser $17,400 in connection with the cost of computing
the Fund's net asset value which is  included in  miscellaneous  expenses in the
Statement of Operations.

7. LINE OF CREDIT.  The Fund has access to an unsecured  line of credit of up to
$25,000,000  from the  custodian for temporary  borrowing  purposes.  Borrowings
under this  arrangement  bear  interest at 0.75% above the Federal Funds rate on
outstanding  balances.  During the six months  ended June 30, 2004 there were no
borrowings from the line of credit.

8. SHARES OF  BENEFICIAL  INTEREST.  The Fund  offers four  classes of shares --
Class AAA Shares,  Class A Shares,  Class B Shares and Class C Shares. Class AAA
Shares are offered through selected broker/dealers without a sales charge. Class
A Shares  are  subject to a maximum  front-end  sales  charge of 5.75%.  Class B
Shares are subject to a contingent  deferred sales charge (CDSC) upon redemption
within six years of purchase and  automatically  convert to Class A Shares after
eight  years  of the  original  purchase.  The  applicable  CDSC is  equal  to a
declining  percentage of the lesser of the net asset value per share at the date
of original  purchase or at the date of redemption,  based on the length of time
held.  Class C Shares are subject to a 1% CDSC for two years after purchase (one
year beginning May 1, 2004).

Transactions in shares of beneficial interest were as follows:

          shares  of the Fund,  including  the  number  of shares  owned and the
          length of time of ownership;

     o    The name of the candidate,  the candidate's resume or a listing of his
          or her  qualifications  to be a Trustees of the Fund and the  person's
          consent  to be named  as a  Trustees  if  selected  by the  Nominating
          Committee and nominated by the Board of Trustees; and

     o    If  requested  by the  Nominating  Committee,  a completed  and signed
          directors questionnaire.

The shareholder  recommendation and information  described above must be sent to
the Fund's Secretary c/o Gabelli Funds, LLC, James E. McKee and must be received
by the  Secretary  no less than 120 days  prior to the  anniversary  date of the
Fund's most recent annual meeting of  shareholders  or, if the meeting has moved
by more than 30 days, a reasonable amount of time before the meeting.

The Nominating Committee believes that the minimum qualifications for serving as
a  Trustees  of the Fund are that the  individual  demonstrate,  by  significant
accomplishment in his or her field, an ability to make a meaningful contribution
to the Board of Trustees'  oversight of the business and affairs of the Fund and
have an impeccable  record and reputation for honest and ethical conduct in both
his or her professional  and personal  activities.  In addition,  the Nominating
Committee  examines  a  candidate's   specific   experiences  and  skills,  time
availability in light of other commitments,  potential conflicts of interest and
independence  from management and the Fund. The Nominating  Committee also seeks
to have  the  Board  of  Trustees  represent  a  diversity  of  backgrounds  and
experience.

         90 days of the filing date of the report that  includes the  disclosure
         required by this paragraph, based on their evaluation of these controls
         and  procedures  required by Rule  30a-3(b)  under the 1940 Act (17 CFR

         240.15d-15(b)).


     (b) There  were  no  changes  in the  registrant's  internal  control  over
         financial reporting (as defined in Rule 30a-3(d) under the 1940 Act (17
         CFR  270.30a-3(d))  that occurred during the  registrant's  last fiscal
         half-year (the  registrant's  second fiscal half-year in the case of an
