TO OUR SHAREHOLDERS
- -------------------------------------------------------------------------------

CGM Capital Development Fund's total return during the fourth quarter of 2004
was 9.6% compared to the unmanaged Standard and Poor's 500 Index which returned
9.2% over the same period. For the year just ended, CGM Capital Development Fund
returned 18.2% and the unmanaged S&P 500 Index returned 10.9%.

THE YEAR IN REVIEW AND ECONOMIC OUTLOOK
The economy continued to grow stronger in 2004. Quarterly growth in Gross
Domestic Product ranged between 3.0% and 4.0% each quarter in real terms and
corporate profits, capital spending and business productivity all reported
advances at year-end. New housing construction continued to be reasonably strong
throughout the year as mortgage rates remained attractive despite the Federal
Reserve Board's five quarter-point hikes in the Federal Funds rate in 2004. And,
though the recovery has spawned new jobs, the numbers were not enough to
substantially reduce the unemployment rate, which was 5.4% at year-end.

Perhaps most appealing about this particular moment in the recovery is the
absence of imbalances. We neither have a fully employed economy with inflation
nor are we in recession. The consumer is still in a spending mood, but
moderately so. Retail sales are up relative to year-earlier periods and the
Consumer Confidence Index bounced nicely from 92.6 in November to 102.3 at
year-end. In the midst of all this, the biggest surprise of 2004 has been the
trend of long-term interest rates--despite a business expansion, rising oil
prices and a weak US dollar, long-term interest rates have remained mostly
steady or a little down over the past year.

Up to this point, foreign countries have continued to buy dollar-denominated
assets despite their dwindling purchasing power. The question is how long will
this buying continue. Short term, a weaker dollar bolsters exports and corporate
profits, but over a longer horizon may prove to be inflationary and a precursor
to higher interest rates.

The equity market as measured by the Standard and Poor's 500 Index was largely
stagnant for the first nine months of the year. Signs of life appeared in the
fourth quarter when the S&P rose 9.2% lifting leading averages to reflect an
improved outlook for corporate profits. We believe the greatest market values
lie in the more cyclical areas of the economy and the greatest risks lie in the
declining dollar, higher oil prices and increasing interest rates.

PORTFOLIO STRATEGY
CGM Capital Development Fund remained fully invested throughout 2004 in
expectation of continued economic growth. Housing and building materials stocks,
the largest industry concentration at the beginning of the year, were eliminated
to make room for other opportunities. The Fund maintained a large concentration
of metal producing stocks during the year and increased the position of steel
producing and processing securities within this category as the year progressed.
The Fund started the year with a modest investment in energy and oil-related
securities which was increased to more than 28% of the portfolio at year end to
become the Fund's largest sector concentration.

The Fund's largest sector gains were in steel and related companies. Other
significant profit contributors were investments in Urban Outfitters, Inc., a
small specialty retailer, and GOL Linhas Aereas Inteligentas SA ADR, a small but
growing Brazilian airline. The Fund's largest losses during the year were in
John B. Sanfilippo & Son, Inc. (food processing) and AU Optronics Corporation
ADR (manufacturer of flat panel displays for televisions and computers). These
securities are no longer held in the portfolio.

On December 31, 2004, CGM Capital Development Fund's three largest industry
positions were in the steel and telephone industries and in independent oil
production. The Fund's three largest holdings were GOL Linhas Aereas
Inteligentas S.A. ADR, Commercial Metals Company and Mobile TeleSystems OJSC
ADR.

The performance data contained in the report represent past performance, which
is no guarantee of future results. The graph and table above do not reflect the
deduction of taxes a shareholder would pay on Fund distributions or the
redemption of Fund shares and assumes the reinvestment of all Fund
distributions. The investment return and the principal value of an investment in
the Fund will fluctuate so that investors' shares, when redeemed, may be worth
more or less than their original cost. Current performance may be lower or
higher than the performance data quoted.

FUND EXPENSES

As a shareholder of the Capital Development Fund, you incur two types of
costs: (1) transaction costs, which could include, among other charges, wire
fees and exchange fees for certain types of accounts and (2) ongoing costs,
including management fees and other Fund expenses. This Example is intended to
help you understand your ongoing costs (in dollars) of investing in the Fund
and to compare these costs with the ongoing costs of investing in other mutual
funds.

The Example is based on an investment of $1,000 invested at the beginning of
the period and held for the entire period July 1, 2004 to December 31, 2004.

ACTUAL RETURN AND EXPENSES

The first line of the table below provides information about actual account
values and actual expenses. You may use the information in this line, together
with the amount you invested, to estimate the expenses that you paid over the
period. Simply divide your account value by $1,000 (for example, an $8,600
account value divided by $1,000 = 8.6), then multiply the result by the number
in the first line under the heading entitled "Expenses Paid During Period" to
estimate the expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Fund's actual expense
ratio and an assumed rate of return of 5% per year before expenses, which is
not the Fund's actual return. The hypothetical account values and expenses may
not be used to estimate the actual ending account balance or expenses you paid
for the period. You may use this information to compare the ongoing costs of
investing in the Fund and other funds. To do so, compare this 5% hypothetical
example with the 5% hypothetical examples that appear in the shareholder
reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs. Therefore, the
second line of the table is useful in comparing ongoing costs only, and will
not help you determine the relative total costs of owning different funds. In
addition, if these transactional costs were included, your costs would have
been higher.

NOTES TO FINANCIAL STATEMENTS -- DECEMBER 31, 2004

1.  The Fund is organized as a Massachusetts business trust under the laws of
Massachusetts pursuant to an Agreement and Declaration of Trust. The Fund is
registered under the Investment Company Act of 1940 as a diversified, open-end
management investment company. Along with three other funds in a separate
Trust, there are four CGM Funds. The Fund's objective is long-term capital
appreciation. The Fund seeks to attain its objective by investing in the
equity securities of a relatively small but diverse group of companies and
industries.

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 accordance with accounting principles
generally accepted in the United States of America 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.

A.  SECURITY VALUATION -- Equity securities are valued on the basis of
    valuations furnished by a pricing service, authorized by the Board of
    Trustees. The pricing service provides the last reported sale price for
    securities listed on a national securities exchange or, in the case of the
    NASDAQ national market system, the NASDAQ official closing price. For
    securities with no sale reported and in the case of over-the-counter
    securities not so listed, the last reported bid price is used.  Short-term
    investments having a maturity of sixty days or less are stated at
    amortized cost, which approximates value. Other assets and securities
    which are not readily marketable will be valued in good faith at fair
    value using methods determined by the Board of Trustees.

B.  SECURITY TRANSACTIONS AND RELATED INVESTMENT INCOME -- Security
    transactions are accounted for on the trade date (date the order to buy or
    sell is executed) and dividend income is recorded on the ex-dividend date
    net of applicable foreign taxes. Interest income is recorded on the
    accrual basis. Net gain or loss on securities sold is determined on the
    identified cost basis.

C.  FEDERAL INCOME TAXES -- It is the Fund's policy to comply with the
    requirements of the Internal Revenue Code applicable to regulated
    investment companies, and to distribute to its shareholders all of its
    taxable income and net realized capital gains, within the prescribed time
    period. Accordingly, no provision for federal income tax has been made. At
    December 31, 2004, there were capital loss carryovers available to offset
    future realized gains of $1,538,498 expiring in year 2010. During the year
    2004 the Fund utilized $108,749,336 of capital loss carryovers.

D.  DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS -- Dividends and distributions
    are recorded by the Fund on the ex-dividend date. The classification of
    income and capital gains distributions is determined in accordance with
    income tax regulations. Distributions from net investment income and
    short-term capital gains are treated as ordinary income for income tax
    purposes. Permanent book and tax differences relating to shareholder
    distributions may result in reclassifications to paid-in capital or
    accumulated realized gain/loss. These differences are primarily related to
    net investment loss write off and foreign exchange gains/losses.
    Undistributed net investment income or accumulated net investment loss may
    include temporary book and tax differences such as tax deferral of losses
    on wash sales, which will reverse in a subsequent period. Any taxable
    income or gain remaining at fiscal year end is distributed in the
    following year.

E.  FOREIGN CURRENCY TRANSLATION -- All assets and liabilities initially
    expressed in terms of foreign currencies are translated into U.S. dollars.
    Transactions affecting statement of operations accounts and net realized
    gain/(loss) on investments are translated at the rates prevailing at the
    dates of the transactions. The Fund does not isolate that portion of the
    results of operations resulting from changes in foreign exchange rates on
    investments from the fluctuations arising from changes in market prices of
    securities held. Such fluctuations are included with the net realized and
    unrealized gain or loss from investments. Reported net realized foreign
    exchange gains or losses arise from sales of foreign currency, currency
    gains or losses realized between the trade and settlement dates on
    securities transactions and the difference between the amounts of
    dividends, interest, and foreign withholding taxes recorded on the Fund's
    books and the U.S. dollar equivalent of the amounts actually received or
    paid. Net unrealized foreign exchange gains or losses arise from changes
    in the value of assets and liabilities other than investments in
    securities at the end of the period, resulting from changes in the
    exchange rate.

2.  INVESTMENT RISK -- There are certain additional risks involved in
investing in foreign securities that are not inherent in investments in
domestic securities. These risks may involve adverse political and economic
developments and the possible imposition of currency exchange blockages or
other foreign governmental laws or restrictions. In addition, the securities
of some foreign companies and securities markets are less liquid and at times
more volatile than securities of comparable U.S. companies and U.S. securities
markets.

3.  PURCHASES AND SALES OF SECURITIES -- For the period ended December 31,
2004, purchases and sales of securities other than United States government
obligations and short-term investments aggregated $954,892,244 and
$986,481,989, respectively. There were no purchases or sales of United States
government obligations.

4.  A.  MANAGEMENT FEES -- During the period ended December 31, 2004, the Fund
        incurred management fees of $3,623,397 paid or payable to the Fund's
        investment adviser, Capital Growth Management Limited Partnership
        (CGM), certain officers and directors of which are also officers and
        trustees of the Fund. The management agreement provides for a fee at
        the annual rate of 1.00% on the first $500 million of the Fund's
        average daily net assets, 0.95% of the next $500 million and 0.80% of
        such assets in excess of $1 billion.

    B.  OTHER EXPENSES -- CGM performs certain administrative, accounting,
        compliance and other services for the Fund. The expenses of those
        services, which are paid to CGM by the Fund, include the following:
        (i) expenses for personnel performing bookkeeping, accounting, and
        financial reporting functions and clerical functions relating to the
        Fund; (ii) expenses for services required in connection with the
        preparation of registration statements and prospectuses, shareholder
        reports and notices, proxy solicitation material furnished to
        shareholders of the Fund or regulatory authorities and reports and
        questionnaires for SEC compliance; (iii) registration, filing and
        other fees in connection with requirements of regulatory authorities;
        and (iv) compliance in connection with the Sarbanes Oxley Act of 2002.
        The Accounting and Administration expense of $58,618, for the period
        ended December 31, 2004, is shown separately in the financial
        statements.

    C.  TRUSTEES FEES AND EXPENSES -- The Fund does not pay any compensation
        directly to its officers or to any trustees who are directors,
        officers or employees of CGM, or any affiliate of CGM (other than
        registered investment companies). For the period ended December 31,
        2004, each disinterested trustee was compensated by the CGM Funds with
        an annual fee of $50,000 plus travel expenses for each meeting
        attended. The trustees are responsible for the audit committee
        functions of the Funds and have designated a chairman to oversee these
        functions who receives an additional $30,000 annually. Of these
        amounts, each fund is responsible for $7,000 per trustee annually,

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Trustees and Shareholders of CGM Capital Development Fund:

In our opinion, the accompanying statement of assets and liabilities, including
the schedule of investments, and the related statements of operations and of
changes in net assets and the financial highlights presents fairly, in all
material respects, the financial position of CGM Capital Development Fund (the
"Fund") at December 31, 2004, the results of its operations, the changes in its
net assets and the financial highlights for the periods indicated, in conformity
with accounting principles generally accepted in the United States of America.
These financial statements and financial highlights (hereafter referred to as
"financial statements") are the responsibility of the Fund's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these financial statements in accordance
with the standards of the Public Company Accounting Oversight Board (United
States). Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits, which included confirmation of securities at December 31, 2004 by
correspondence with the custodian and brokers, provide a reasonable basis for
our opinion.

The Fund is supervised by the board of trustees (the "Board") of the Trust. The Board is responsible for the general oversight of
the Fund, including general supervision and review of the Fund's investment activities. The Board, in turn, elects the officers who

Investment Company Act of 1940. Each trustee and officer of the Trust noted as an interested person is interested by virtue of that
individual's position with Capital Growth Management Limited Partnership ("CGM"), the Fund's investment adviser, as described in
the table below. Each trustee serves during the continued lifetime of the Trust or until he earlier dies, resigns or is removed, or
if sooner, until the election and qualification of his successor. Each officer serves until his or her successor is elected or
qualified or until the officer sooner dies, resigns, or is removed or becomes disqualified.

The trustees and officers of the Trust, their ages, their principal occupations during the past five years, the number of CGM Funds
they oversee, and other directorships they hold are set forth below. Unless otherwise noted below, the address of each interested
trustee and officer is One International Place, Boston, Massachusetts 02110. Correspondence intended for the trustees who are not
