Dear Shareholders,
                                                               December 11, 2003

THE YEAR IN REVIEW

      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  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 in
2003,  as it was in 2002.  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%, just below its peak of
6.4%.

      By the end of our fiscal  year,  the  public  mood had  shifted.  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.  The S&P 500 rose 19%,  while the
Nasdaq Composite was up a staggering 45%. Interest rates and inflation  remained
low,  though  interest rates did increase as the economy picked up. The yield on
the US Treasury 10-year note was pushed up to 4.30% at October 31, up from 3.89%
a year earlier.

PORTFOLIO MATTERS

Alger LargeCap Growth Institutional Portfolio

      The Alger  LargeCap  Growth  Institutional  Portfolio  increased by 23.10%
during the 12 months ended October 31, 2003, while the Russell 1000 Growth Index
increased by 21.81%.  Reasons we outperformed:  first, a solid  overweighting of
the  technology  sector,  at more than 28% of the  portfolio,  was key,  as this
sector led




                                                                             -2-

the market  recovery,  with strong returns from Intel,  Veritas,  and Cisco; and
second,  a similar  overweighting  in  consumer  stocks  where  both  retail and
internet  stocks like Best Buy and eBay performed  well. In both sectors,  stock
selection was a strong positive contributor. Our stocks outperformed the Russell
1000 Growth Index in every sector except for telecommunication services. We were
market  weighted in health care stocks,  at just over 26% of the portfolio,  and
performed in line with the sector  here.  We were hurt by Tenet  Healthcare  and
HCA,  but  these  were  offset by strong  performers  such as Boston  Scientific
Corporation.  A  notable  misjudgment  was  General  Dynamics,  which we sold in
frustration at or near the low for the year.

Alger Small Cap Institutional Portfolio

      The Alger Small Cap  Institutional  Portfolio  grew  37.65%  during the 12
months ended October 31, 2003,  while the Russell 2000 Growth Index grew 46.53%.
Our  information  technology  holdings,  representing  an  average of 27% of the
portfolio, did quite well, but underperformed the Russell 2000 Growth Index. Our
industrial stocks were slightly above market weight,  and performance was mixed.
Our holdings in for-profit education stocks were strong, but our performance was
hurt  by  our  holdings  in  capital  goods  stocks.   Actuant  Corporation,   a
manufacturer of high-end  hydraulic  equipment and tools,  suffered losses as it
faced a  cautious  customer  base,  and was  forced to trim its  workforce.  Our
holdings  in  the  health  care  sector  represented  an  average  of 20% of the
portfolio,  and  underperformed  the Russell 2000 Growth Index.  Performance was
helped  by  companies  such as  Pharmaceutical  Resources,  a  manufacturer  and
distributor  of generic  drugs,  but was hurt by holdings in several health care
equipment  makers  such  as  Steris.   Our  holdings  in  the  financial  sector
outperformed the Russell 2000 Growth Index, with strong returns from stocks such
as Doral Financial Corp., a bank that specializes in mortgages, and has a strong
presence in Puerto Rico where the housing market is rapidly expanding.

Alger MidCap Growth Institutional Portfolio

      The Alger MidCap Growth  Institutional  Portfolio increased 37.36% for the
12 months  ended  October  31,  2003,  while the  Russell  MidCap  Growth  Index
increased  39.31%.  Things  we got  right:  in the  consumer  sector,  where the
portfolio had over 23% of its assets, we sharply outperformed the Russell MidCap
Growth Index, with total returns of just over 79%. This was due to our early and
significant  positions in NetFlix,  an innovative  provider of DVDs by mail, and
other exciting growth companies like XM Satellite Radio,  Leapfrog  Enterprises,
Tractor  Supply,  Amazon and Urban  Outfitters.  The  portfolio  was hurt by our
holdings in energy stocks, which as a sector  significantly  trailed the returns
of the rest of the  market;  we reduced  our  exposure  to this  sector over the
course  of the year.  An  average  of 27% of the  portfolio  was in  information
technology  stocks,  which  contributed to favorable




                                                                             -3-

returns for the portfolio. Corporate spending on IT has shown steady improvement
throughout  the year.  One big loser was BISYS Group,  a provider of outsourcing
and back-office services for financial institutions,  which hurt our performance
in this sector.

Alger Capital Appreciation Institutional Portfolio

      The Alger Capital Appreciation Institutional Portfolio increased by 23.30%
for the 12 months ended  October 31,  2003,  while the Russell 3000 Growth Index
increased  by  23.34%.  More  than  27% of the  portfolio  holdings  were in the
information  technology   sector,   which   experienced   superior  returns  and
outperformed the Russell 3000 Growth Index. Stocks such as Yahoo! Inc., a global
internet  business and consumer  services  company,  and National  Semiconductor
Corporation,  a maker of analog  microchips,  experienced triple digit gains. We
were above market  weight in health care stocks,  at 31% of the  portfolio,  and
outperformed  the  Russell  3000  Growth  Index.  While the  performance  of our
holdings in this sector was mixed, strong performance from stocks such as Zimmer
Holdings and Boston Scientific Corp. boosted our overall returns.  The portfolio
suffered from our holdings in the consumer  staples  sector,  but we trimmed our
positions in this sector over the course of the year and therefore  were able to
reduce the overall impact on the portfolio's performance.

Alger Balanced Institutional Portfolio

      The Alger Balanced Institutional  Portfolio increased by 11.09%, while the
Russell  1000  Growth  Index   increased  by  21.81%  and  the  Lehman  Brothers
Government/Credit   Bond  Index  rose  6.18%.   Information   technology  stocks
represented  approximately  29% of the portfolio,  and  outperformed the Russell
1000  Growth  Index.  Our  performance  in this  sector was  boosted by superior
returns  from Intel  Corporation,  Yahoo!  Inc.,  and Cisco  Systems,  Inc.  Our
holdings  in the  consumer  discretionary  sector were above  market  weight and
out-performed the Russell 1000 Growth Index.  Internet and retailing stocks like
eBay and Best Buy were large  contributors  to our  overall  returns.  The fixed
income portion of the portfolio  benefited from its above market weight position
in corporate bonds and its underweight position in Treasuries.  Corporate credit
outperformed  Treasuries as the economy improved,  as corporations  reduced debt
levels, and as interest rates rose in response to increased economic activity.

Alger Socially Responsible Growth Institutional Portfolio

      The Alger Socially Responsible Growth Institutional Portfolio increased by
21.44% for the 12 months ended  October 31, 2003,  while the Russell 3000 Growth
Index increased by 23.34%.  More than 27% of the portfolio  holdings were in the
information   technology   sector,   which  experienced   superior  returns  and
outperformed the Russell 3000 Growth Index. Stocks such as Yahoo! Inc., a global
inter-





                                                                             -4-

net  business  and  consumer  services  company,   and  National   Semiconductor
Corporation,  a maker of analog  microchips,  experienced triple digit gains. We
were above services.  We were market weighted in the health care stocks, at just
over 26% of the  portfolio,  and performed in line with the sector here. We were
hurt by Tenet  Healthcare  and HCA,  but these were offset by strong  performers
such as  Boston  Scientific  Corporation.  A  notable  misjudgment  was  General
Dynamics, which we sold in frustration at or near the low for the year.

LOOKING AHEAD

      As we head into 2004, we believe that the economy will continue to grow at
a strong pace.  Trillions  of dollars sit in money market and savings  accounts,
and as the economy  continues to grow  steadily,  we believe that investors will
look to put those dollars to more productive use in the equity markets. We think
that as investors search for better returns on their capital, high quality, high
growth companies should do well. Fundamentally,  these tend to be companies with
management teams that not only led their  organizations  through the downturn of
the last three  years,  but looked  forward  while doing so. They  continued  to
invest in their products and services,  and they should reap the benefits if the
economy accelerates in 2004.

      True,  many people are  unsettled by the  situation  in Iraq,  the federal
deficit,  and most  importantly,  the job market.  But consumer  demand  remains
strong and business  spending  continues to increase.  The result should be wage
increases or job creation,  or both. We expect that  consumers  will continue to
hold up the economy as they have always done. Home mortgage refinancing activity
has begun to slow, but federal  spending and tax cuts should continue to provide
economic  liquidity  well  into  2004.  And  as  a  general  rule,  Wall  Street
consistently  underestimates  the  ability  of  consumers  to find  new  ways to
maintain spending, so we are not convinced about the recent predictions that the
consumer may be tapped out.

      Other signs are also encouraging. Mergers and acquisitions are a necessary
component  of a healthy  economy.  At a  minimum,  M&A  activity  is a sign that
business leaders are optimistic  enough about future prospects in their industry
that they feel  confident to take risks.  October 2003 was the biggest month for
M&A deals since July 2001,  and we expect  that M&A  activity  will  continue to
increase in the coming fiscal year.

      In short,  we believe  the year ahead is likely to be shaped by an economy
expanding between 3.5% and 4% annually and by rational  exuberance in the equity
markets.  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.





                                                                             -5-

      We hope that we have  served you well this  year.  We know that the issues
surrounding   trading  activities  in  the  mutual  fund  industry  have  raised
questions,  and we are doing  everything  we can to address  your  concerns  and
justify  your  confidence  in  us.  You  have  entrusted  us to  find  the  best
investments, and we hope that we will continue to earn that trust. We strive for
the utmost rigor and integrity in our investment process,  and going forward, we
are  committed  to making sure that every  aspect of our company is run with the
same integrity.

   investment  made in the  Alger  Capital  Appreciation  Institutional  Class I
   shares and the Russell 3000 Growth Index on November 8, 1993,  the  inception
   date of the Alger Capital Appreciation  Institutional Class I shares. Figures
   for the  Alger  Capital  Appreciation  Institutional  Class I shares  and the
   Russell  3000 Growth  Index (an  unmanaged  index of common  stocks)  include
   reinvestment  of dividends.  Performance  for the Alger Capital  Appreciation
   Institutional  Class R shares may vary from the  results  shown  above due to
   differences in expenses the class bears.

THE ALGER INSTITUTIONAL FUND
NOTES TO FINANCIAL STATEMENTS

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 an
unlimited  number of shares of beneficial  interest in six  portfolios--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.





                                                                            -43-
THE ALGER INSTITUTIONAL FUND
NOTES TO FINANCIAL STATEMENTS (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 custodian 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 October 31, 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-





                                                                            -44-

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,  2003,  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
$261,009, $710,692, $2,845,362,  $810,731, $388 and $19,332, respectively,  from
undistributed net investment income (accumulated loss) and $0, $0, $0, $0,  $392
and $19,332,  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, 2003, 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  $46,816,979,  $94,026,601,
$27,943,965,  $133,629,281, $8,862 and $0, respectively, and expire 2008 through
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,

THE ALGER INSTITUTIONAL FUND
NOTES TO FINANCIAL STATEMENTS (CONTINUED)

NOTE 8--REGULATORY MATTERS:

      The  Office of the New York  State  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.  In response to these  inquiries,  Alger Management and its counsel have
been investigating  certain shareholder trading practices,  both in the Fund and
in other  mutual  funds that it manages  (the  "Funds").  Alger  Management  has
assured the board that if it is determined  that improper  trading  practices in
the Fund  detrimentally  affected its  performance,  Alger  Management will make
restitution.  At the present  time,  Alger  Management is unable to estimate the
impact, if any, that the outcome of these  investigations may have on the Fund's
results of operations or financial conditions.

      On October 16,  2003,  the SEC  commenced  and settled a civil  proceeding
against a former  vice  chairman  of Alger  Management's  immediate  parent,  in
connection with alleged market timing arrangements with certain investors in the
Fund.  That  settlement  specifically  provided:  "The findings  herein are made
pursuant to [the former vice chairman's settlement] Offer and are not binding on
any other  person or entity  in this or any  other  proceeding."  Neither  Alger
Management nor any of the Funds was a party to this proceeding.

      On October, 31, 2003, Peter D. DeMayo, as Custodian for James Liam DeMayo,
identifying  himself as a shareholder of Spectra Fund,  filed a purported  class
action lawsuit against the Fund,  Spectra Fund,  various portfolios of the Fund,
Alger Management,  and the former vice chairman (the "fund  defendants"),  Veras
Management  Partners,  LLP et al., in the United States  District  Court for the
Southern  District of New York, and served the complaint in the lawsuit on Alger
Management  and the fund  defendants  on  November  10,  2003.  The suit,  based
primarily upon the SEC settlement  with a former vice chairman,  alleges,  among
other things,  that the fund defendants made false and misleading  statements in
their  prospectuses  in violation of Section 11 of the  Securities  Act of 1933,
that other defendants  violated the "control person" provisions of Section 15 of
the  Securities  Act and Section 20(a) of the  Securities  Exchange Act of 1934,
that  all  defendants  committed  fraud in  violation  of  Section  10(b) of the
Securities  Exchange Act and Rule 10b-5  thereunder,  and that Alger  Management
breached a fiduciary  duty to  plaintiffs.  The suit seeks,  among other things,
compensatory  damages,  recovery of advisory fees paid to Alger Management,  and
payment of the plaintiff's counsel and expert fees.

      Other  related  class  actions have been  commenced  making  substantially
similar  allegations  on behalf of the same  putative  class.  All these related
class  actions will be  consolidated  in accordance  with the  provisions of the
Private Securities Litigation Reform Act.





                                                                            -51-
THE ALGER INSTITUTIONAL FUND
NOTES TO FINANCIAL STATEMENTS (CONTINUED)

      On November 25,  2003,  plaintiff,  Michael  Bernstein,  as custodian  for
Judith  Bernstein,  commenced  an action  derivatively  on behalf of "the  Alger
Funds" against Alger Management,  a former vice chairman of its parent and Veras
Management Partners,  LLP in the U.S. District Court for the Eastern District of
New York. In this  shareholder  derivative  action,  plaintiff  seeks to recover
monies on behalf of "the Alger Funds" for the  purportedly  wrongful  conduct of
defendants,  including  an alleged  violation  of  Section 36 of the  Investment
Company  Act by Alger  Management  and the former vice  chairman  and an alleged
breach of fiduciary duty by Alger Management and the former vice chairman.

      Alger  Management  does not  believe  that  the  foregoing  lawsuits  will
materially  affect its ability to perform its  management  contracts with any of
the funds that it manages,  and the management of the Fund believes that it will
not be materially adversely affected by the pending lawsuits.





                                                                            -52-

                         REPORT OF INDEPENDENT AUDITORS

To the Shareholders and Board of Trustees of
  The Alger Institutional Fund:

      We have audited the  accompanying  statements  of assets and  liabilities,
including  the  schedules  of  investments,  of  The  Alger  Institutional  Fund
(comprising the LargeCap Growth Institutional,  Small Cap Institutional,  MidCap
Growth Institutional, Capital Appreciation Institutional, Balanced Institutional
and Socially  Responsible  Growth  Institutional  Portfolios)  as of October 31,
2003, and the related  statements of operations for the year then ended, and the
statements 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 each of the respective  portfolios  constituting The Alger
Institutional  Fund at October 31, 2003, the results of their operations for the
year  then  ended,  and the  changes  in  their  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.
