                                     [LOGO]





Dear Shareholders,

                                                                   June 16, 2003


      Slow, steady economic growth; reliable consumers;  tentative corporations;
and war. That is the short answer to the question:  what happened during the six
months  ended  April  30?  The last two  months of 2002 saw the  equity  markets
recover  from their lows of October  9,  though a  significant  portion of those
gains were in  technology  stocks  and were then given up in the first  weeks of
2003 because the fundamentals had not yet improved.

      However,  throughout this period,  the economy remained in a steady growth
pattern.  It was not a dramatic period.  Consumer spending accounted for most of
the economic  growth.  Consumers were aided by historically  low interest rates,
already  well below 4% on the 10-year note by April and  continually  decreasing
thereafter.  Low rates led to another  wave of mortgage  refinancing,  which put
more money in people's pockets.  That refinancing boom,  combined with increased
federal spending, tax cuts, and a Federal Reserve that has kept short-term rates
very low, buoyed consumer  spending during a time of weak employment,  tentative
companies, and tumultuous international affairs.

      A cold and snowy February of 2003 combined with rising tension and concern
about Iraq dampened  economic  activity  across the board.  Consumers pared back
purchases on certain  items,  and  companies  were loathe to  undertake  capital
expenditures  ahead of the war. As a result,  the economy grew at an annual rate
of less than 2% for the first quarter of 2003. However,  when it became clear in
early March that war was inevitable,  the markets rallied. It is often said that
the  markets  hate  uncertainty.  The rally that began in March was  certainly a
testament to that notion.  The markets  seesawed during the uncertain first days
of the war, but then resumed their upward  movement as Saddam  Hussein's  regime
crumbled.  The result was that from November 1, 2002 through April 30, 2003, the
Dow rose 2.1%, the S&P 500 was up 4.5%, and the NASDAQ gained 10.1%.

      Now,  for the first time in over two years,  Wall Street has begun to look
to the future.  Companies that can show healthy balance sheets and an ability to
improve  productivity  and expand their  businesses  are becoming  attractive to
investors.  That is as it  should  be,  but it has not been the case for quite a
while.  The markets and the country in general are  beginning to emerge from two
years  that  included a  recession,  terrorism,  war,  and  corporate  scandals.
Sentiment has slowly been shifting away from fear and toward guarded hope.  That
shift should lead to support for higher levels for the equity markets. That does
not mean a return to  irrational  exuberance,  but it does mean a more  balanced
market where good companies and good stock picking are rewarded.

      Respectfully submitted,

      /s/ Dan C. Chung

NOTES TO FINANCIAL STATEMENTS (UNAUDITED)


NOTE 1--GENERAL:

      The Alger Institutional Fund (the "Fund"),  which was The Alger Retirement
Fund prior to March 1, 2002, is a diversified,  open-end  registered  investment
company  organized  as a business  trust under the laws of the  Commonwealth  of
Massachusetts.  The Fund operates as a series  company and currently  issues six
Portfolios of shares of beneficial interest  --LargeCap Growth Portfolio,  Small
Cap Portfolio, MidCap Growth Portfolio, Capital Appreciation Portfolio, Balanced
Portfolio and Socially Responsible Growth Portfolio (the "Portfolios"). Prior to
March 1, 2002,  the LargeCap  Growth  Portfolio  was the Growth  Portfolio.  The
LargeCap Growth Portfolio, Small Cap Portfolio, MidCap Growth Portfolio, Capital
Appreciation Portfolio and Socially Responsible Growth Portfolio normally invest
primarily in equity securities and each has an investment objective of long-term
capital appreciation. The Balanced Portfolio's investment objectives are current
income and  long-term  capital  appreciation  which it seeks to achieve  through
investing in equity and fixed income securities.

      Each  Portfolio  offers  Class I and Class R shares.  Class R shares  were
first offered  January 27, 2003.  Each class has identical  rights to assets and
earnings  except that only Class R shares have a plan of  distribution  and bear
the related expenses.

NOTE 2--SIGNIFICANT ACCOUNTING POLICIES:

(a) INVESTMENT  VALUATION:  Investments of the Portfolios are valued on each day
the New York  Stock  Exchange  (the  "NYSE") is open as of the close of the NYSE
(currently  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 Trustees.

      Short-term  securities  having a remaining  maturity of sixty days or less
are valued at amortized cost which approximates  market value.  Shares of mutual
funds are  valued at the net asset  value of the  underlying  mutual  fund.

(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  identified  cost basis.  Dividend  income is
recognized  on the  ex-dividend  date and interest  income is  recognized on the
accrual basis.

      Premiums  and  discounts on debt  securities  purchased  are  amortized or
accreted over the lives of the respective securities.

NOTES TO FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED)


(c) REPURCHASE AGREEMENTS:  The Portfolios enter into repurchase agreements with
approved  institutions.  The repurchase  agreements are  collateralized  by U.S.
Government securities, which are either received and held in physical possession
by the custo dian or received by such  custodian in book-entry  form through the
Federal  Reserve  book-entry  system.  The collateral is valued on a daily basis
during the term of the  agreement to ensure that its value equals or exceeds the
agreed-upon  repurchase  price  to  be  repaid  to  the  Portfolio.   Additional
collateral is obtained when necessary.

(d) LENDING OF PORTFOLIO  SECURITIES:  The Portfolios  lend their  securities to
financial institutions,  provided that the market value of the securities loaned
will not at any time  exceed  one  third of the  Portfolio's  total  assets,  as
defined.  The Portfolios earn fees on the securities loaned,  which are included
in interest  income in the  accompanying  Statements of Operations.  In order to
protect  against the risk of failure by the  borrower  to return the  securities
loaned  or  any  delay  in  the  delivery  of  such  securities,   the  loan  is
collateralized by cash, letters of credit or U.S. Government securities that are
maintained  in an amount  equal to at least 100  percent of the  current  market
value of the loaned  securities.  The market value of the loaned  securities  is
determined  at  the  close  of  business  of the  Portfolios  and  any  required
additional  collateral is delivered to the  Portfolios on the next business day.
At April 30,  2003,  the value of  securities  loaned  and  collateral  received
thereon were as follows:

                                                  VALUE OF
                                                 SECURITIES         VALUE OF
                                                   LOANED          COLLATERAL
                                                 -----------       -----------

Socially Responsible
  Growth Portfolio ............................           --                --

(e) DIVIDENDS TO SHAREHOLDERS: Dividends payable to shareholders are recorded on
the  ex-dividend  date.  With  respect  to all  Portfolios,  dividends  from net
investment income and distributions from net realized gains,  offset by any loss
carry  forward,  are declared and paid annually after the end of the fiscal year
in which earned.

      Each class is treated  separately in determining  the amounts of dividends
of net investment income and capital gains payable to holders of its shares.

      The  characterization  of  distributions  to  shareholders  for  financial
reporting  purposes is determined in accordance  with federal  income tax rules.
Therefore,  the  source  of the  Portfolios'  distributions  may be shown in the
accompanying financial statements as either from, or in excess of net invest-

ment 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,  2002,  the  LargeCap  Growth  Portfolio,  the  Small Cap
Portfolio,  the MidCap Growth Portfolio, the Capital Appreciation Portfolio, the
Balanced Portfolio and the Socially  Responsible  Growth Portfolio  reclassified
$448,891, $1,387,729, $2,987,425, $1,714,108, $10,570 and $11,800, respectively,
from  undistributed  net  investment  income   (accumulated  loss)  and  $4,303,
$359,645,  $20,841,  $14,329,  $0 and $0,  respectively,  from undistributed net
realized gain (accumulated  loss) to paid-in capital.  Reclassifications  result
primarily  from the  difference in tax treatment of net  operating  losses.  The
reclassifications  had no impact on the net asset values of the  Portfolios  and
are designed to present the Portfolios' capital accounts on a tax basis.

(f)  FEDERAL  INCOME  TAXES:  It is each  Portfolio's  policy to comply with the
requirements  of the Internal  Revenue Code  applicable to regulated  investment
companies and to distribute all of its investment  company taxable income to its
shareholders.  Provided a Portfolio maintains such compliance, no federal income
tax provision is required.  Each  Portfolio is treated as a separate  entity for
the purpose of determining such compliance. At October 31, 2002, the net capital
loss  carryforwards of the LargeCap Growth  Portfolio,  the Small Cap Portfolio,
the MidCap Growth Portfolio,  the Capital Appreciation  Portfolio,  the Balanced
Portfolio and the Socially  Responsible  Growth  Portfolio  which may be used to
offset future net realized gains were approximately  $41,746,316,  $100,928,226,
$71,200,401, $139,093,169, $42,439 and $44,393, respectively, and expire in 2008
and 2010.

(g) ALLOCATION METHODS: The Fund accounts separately for the assets, liabilities
and  operations  of  each  Portfolio.  Expenses  directly  attributable  to each
Portfolio  are  charged  to that  Portfolio's  operations;  expenses  which  are
applicable  to all  Portfolios  are  allocated  among them based on net  assets.
Income,  realized  and  unrealized  gains  and  losses,  and  expenses  of  each
Portfolio,  are allocated  among the  Portfolio's  classes based on relative net
assets,  with the exception of distribution  fees,  which are only applicable to
Class R shares.

(h) 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 3--INVESTMENT MANAGEMENT FEES AND OTHER TRANSACTIONS WITH AFFILIATES:

(a) INVESTMENT MANAGEMENT FEES: Fees incurred by each Portfolio, pursuant to the
provisions of its Investment  Management  Agreement with Fred Alger  Management,
