ITEM 1.  REPORT(S) TO STOCKHOLDERS.

Dear Shareholders,

      The fiscal year ended October 31, 2003, was dramatic, both
economically and politically. It began shortly after the Dow hit a five
year low and ended with a robust recovery.

      At the beginning of 2003, the markets had been down three years in a
row, something that hadn't happened since 1939-1941. Overshadowed by
national security concerns, the markets remained essentially stagnant into
the spring. The looming American-led invasion of Iraq dominated the
headlines and the attention of the American public. In spite of encouraging
economic data, both Wall Street and Main Street were preoccupied with war.
On March 19th, the United States invaded Iraq. The markets then fluctuated
with the perceived progress of the military campaign. Later in the spring,
as the U.S. military achieved success, at least relative to very
pessimistic media opinion, the markets recovered dramatically.

      Throughout 2003, the U.S. economy grew steadily, aided by the Federal
Reserve, by tax policy, and by improving corporate outlooks. On June 25,
2003, the Fed cut the Fed Funds Rate to 1.00%, a 40 year low. The yield on
the 10-year note reached a low of 3.11% on June 13, before climbing back
above 4.00% in July.

      The combination of low interest rates, tax cuts, increased federal
spending and the mortgage refinancing boom boosted the economy
significantly. Fueled by a spike in consumer spending and high
productivity, third quarter GDP growth soared to 8.2%, the highest rate
since 1984. Productivity growth also was exceptional throughout 2003. The
one soft spot was the job market. Historically, there has always been a lag
time between economic recovery and job creation. For the month of October,
the unemployment rate was at 6.0%, below its peak of 6.4%, but still
indicative of less-than-stellar job creation.

      By the end of our fiscal year, both the economy and the markets
experienced remarkable growth, and investors seemed to have gained a level
of rational confidence that was absent from both the bull market of the
late 1990s and the bear market of 2000 through 2002. The Dow rose 17% in
the 12 months ended October 31, 2003, and the S&P 500 rose 19%.

      For the year, fixed-income lagged equities. Within fixed-income, low
yields on Treasuries meant that corporate bonds were relatively more
attractive, and low-quality corporate bonds outperformed during much of the
2nd and 3rd quarters of 2003. Overall, it was better to be concentrated in
lower rated corporate credit, which Castle Convertible Fund was. The Lehman
Brothers Government/Credit Bond Index rose 6.18% in the 12-months ended
October 31, 2003. Over the same period, the Fund was up 12.99%.

      As we head into 2004, we believe the coming year is likely to be
shaped by an economy expanding between 3.5% and 4% annually. We anticipate
that the markets will reflect that. Investors have maintained high
expectations for future earnings. They are optimistic, but cautious, as are
we. Having survived the bubble and the bust, we, like you, would prefer not
to see a repeat of either.

                                       Respectfully submitted,

                                       /s/ Dan C. Chung

CASTLE CONVERTIBLE FUND, INC.
NOTES TO FINANCIAL STATEMENTS

NOTE 1-Summary of Significant Accounting Policies:

      Castle Convertible Fund, Inc. (the "Fund") is registered under the
Investment Company Act of 1940, as a diversified, closed-end management
investment company. The Fund's investment adviser is Fred Alger Management,
Inc. (the "Adviser").

      The following is a summary of significant accounting policies
consistently followed by the Fund in the preparation of its financial
statements.

(a) Investment Valuation-Investments in securities are valued at 4:00 p.m.
Eastern time. Listed and unlisted securities for which such information is
regularly reported are valued at the last reported sales price or, in the
absence of reported sales, at the mean between the bid and asked price or,
in the absence of a recent bid or asked price, the equivalent as obtained
from one or more of the major market makers for the securities to be
valued. Securities for which market quotations are not readily available
are valued at fair value, as determined in good faith pursuant to
procedures established by the Board of Directors. Short-term investments
are valued at amortized cost which approximates market value.

(b) Securities Transactions and Investment Income-Securities transactions
are recorded on a trade date basis. Realized gains and losses from
securities transactions are recorded on the basis of the first-in, first-
out method. Dividend income is recognized on the ex-dividend date and
interest income is recognized on the accrual basis.

      Effective November 1, 2001, premiums and discounts on debt securities
purchased are amortized or accreted over the lives of the respective
securities. This change in accounting policy which has been applied
retroactively had no material effect on the accompanying financial
statements.

(c) Dividends to Shareholders-Dividends payable to shareholders are
recorded by the Fund on the ex-dividend date. Dividends from net investment
income are declared and paid quarterly. Distributions from net
realized gains are declared and paid annually after the end of the fiscal
year in which earned.

      The characterization of distributions to shareholders for financial
reporting purposes is determined in accordance with federal income tax
rules. Therefore, the source of the Fund's distributions may be shown in
the accompanying financial statements as either from, or in excess of net
investment income, net realized gain on investment transactions or paid-in
capital, depending on the type of book/tax differences that may exist.

      At October 31, 2003, the Fund reclassified $488,723 to undistributed
net investment income (accumulated loss) and $205,583 from undistributed
net realized gain (accumulated loss) to paid-in capital. Reclassifications
result primarily from the difference in tax treatment of certain debt
instruments. The reclassification had no impact on the net asset value of
the Fund and is designed to present the Fund's capital accounts on a tax
basis.

(d) 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 all of its taxable income, including
net realized capital gains, to its shareholders. Therefore, no federal
income tax provision is required. At October 31, 2003, the net capital loss
carryforward of the Fund which may be used to offset future net realized
gains was approximately $3,678,369, and expires 2009 through 2011.

(e) Other-These financial statements have been prepared using estimates and
assumptions that affect the reported amounts therein. Actual results may
differ from those estimates.

NOTE 2-Investment Advisory Fees and Other Transactions with Affiliates:

(a) Investment Advisory Fees-Fees incurred by the Fund, pursuant to the
provisions of an Investment Advisory Contract (the "Contract") with the
Adviser, are payable monthly and computed at an annual rate of .75% based
on the Fund's average weekly net asset value.

CASTLE CONVERTIBLE FUND, INC.
NOTES TO FINANCIAL STATEMENTS (Continued)

NOTE 2-Investment Advisory Fees and Other Transactions with Affiliates
 (continued):

      The Contract further provides that if in any fiscal year the
aggregate expenses of the Fund (excluding interest, brokerage commissions,
taxes and extraordinary expenses) should exceed 1.5% of the first $30
million of average net assets and 1.0% of the average net assets of the
Fund over $30 million, the Adviser will reimburse the Fund for such excess
expenses. For the year ended October 31, 2003, no reimbursement was
required pursuant to the Contract. For the year ended October 31, 2003, the
total investment advisory fee charged to the Fund amounted to $391,086, and
the Adviser received $18,000 for bookkeeping services supplied to the Fund
at cost.

(b) Transfer Agent Fees-Alger Shareholder Services, Inc. ("Alger
Services"), an affiliate of the Adviser, serves as transfer agent for the
Fund. During the year ended October 31, 2003, the Fund incurred fees of
approximately $2,000 for services provided by Alger Services and reimbursed
Alger Services approximately $1,000 for transfer agent related expenses
paid by Alger Services on behalf of the Fund.

(c) Directors' Fees-Certain directors and officers of the Fund are
directors and officers of the Adviser and Alger Services. The Fund pays
each director who is not affiliated with the Adviser or its affiliates an
annual fee of $8,000, payable quarterly, which is reduced proportionately
by any meetings not attended during the quarter.

(d) Other Transactions With Affiliates-At October 31, 2003, the Adviser and
its affiliates owned 451,484 shares of the Fund.

NOTE 3-Securities Transactions:

      During the year ended October 31, 2003, purchases and sales of
investment securities, excluding short-term securities, aggregated
$80,442,004 and $76,194,877, respectively.

NOTE 4-Components of Net Assets:

      At October 31, 2003, the Fund's net assets consisted of:



<s>                                    <c>
Paid-in capital                        $53,735,071
Undistributed net investment income        971,255
Undistributed net realized gain
 (accumulated loss)                     (3,716,564)
Net unrealized appreciation              4,054,873
                                       -----------
NET ASSETS                             $55,044,635
                                       ===========


NOTE 5-Distributions to Shareholders:

      Distributions paid from ordinary income during the year ended October
31, 2003, and the year ended October 31, 2002, were $1,945,322 and
$2,526,683, respectively.

      As of October 31, 2003, the components of distributable earnings on a
tax basis were as follows:



<s>                              <c>
Undistributed ordinary income    $  837,229
Undistributed long-term gain
 accumulated (loss)                       -
Capital loss carrryforward        3,678,369
Unrealized appreciation
 (depreciation)                   4,150,833


      The difference between book basis and tax-basis undistributed long-
term gain is attributable primarily to the tax deferral of losses on wash
sales.

NOTE 6-Regulatory Matters:

      The Office of the New York Attorney General, the Massachusetts
Securities Division of the Office of the Secretary of the Commonwealth, and
the United States Securities and Exchange Commission ("SEC") have contacted
Alger Management in connection with their investigation of practices in the
mutual fund industry identified as "market timing" and "late trading" of
mutual fund shares. Alger Management does not believe that the foregoing
investigations will materially affect its ability to perform its management
contracts with any of the funds that it manages.

                       Report of Independent Auditors

To the Shareholders and Board of Directors of
 Castle Convertible Fund, Inc.:

      We have audited the accompanying statement of assets and liabilities
of Castle Convertible Fund, Inc., including the schedule of investments, as
of October 31, 2003, and the related statement of operations for the year
then ended, and the statement of changes in net assets and the financial
highlights for each of the two years then ended. These financial statements
and financial highlights are the responsibility of the Fund's management.
Our responsibility is to express an opinion on these financial statements
and financial highlights based on our audits. The financial highlights for
the three years ended October 31, 2001 were audited by other auditors,
whose report, dated November 30, 2001, expressed an unqualified opinion on
those financial highlights.

      We conducted our audits in accordance with auditing standards
generally accepted in the United States. Those standards require that we
plan and perform the audit to obtain reasonable assurance about whether the
financial statements and financial highlights are free of material
misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. Our
procedures included confirmation of investments in securities as of October
31, 2003, by correspondence with the custodian and brokers. An audit also
includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

      In our opinion, the financial statements and financial highlights
referred to above, and audited by us, present fairly, in all material
respects, the financial position of Castle Convertible Fund, Inc. at
October 31, 2003, the results of its operations for the year then ended,
and the changes in its net assets and the financial highlights for each of
the two years then ended, in conformity with accounting principles
generally accepted in the United States.
