Fellow Shareholders:                                               JULY 23, 1998

A YEAR-TO-DATE REVIEW
For the first half of this year, the market has been divided into three distinct
periods. Each period has exemplified a real economic and stock market theme. The
first began on January 2, the first day of trading, when the Dow closed slightly
below 8000. It lasted exactly one month, ending on January 30. During this time,
the Dow was essentially  flat,  point-to-point.  However,  it did drop as low as
7600 mid-month. The primary theory of the market throughout this period was that
the Asian economic crisis would slow the American economy,  leading to depressed
earnings.

The second  period began on February 2nd when it became  apparent that events in
Asia were not hurting the American  economy.  Moreover,  the Federal Reserve had
retreated to a position of neutrality.  This period  extended  through April 21,
during which time the Dow traded up in a fairly uniform manner with an intra-day
high above 9250. During this stretch, the market came to believe that Asia would
not  affect  the  American  economy  nor  would  the Fed  intervene  by  raising
short-term rates.

The third period began with a WALL STREET JOURNAL  article  suggesting  that the
economy  was so strong that the Fed would have to raise rates at the May Federal
Open-Market Committee meeting to guard against a jump in inflation.  Most of the
economic data certainly did suggest that the economy was growing at a rapid pace
and there  would have been an obvious  case for higher  rates had there been any
signs of rising  inflation.  However,  inflation  continued to drop. At the same
time,  the  situation  in Asia was  deteriorating  to an  alarming  degree.  The
outbreak of rioting in Indonesia  and labor unrest in Korea caused  investors to
worry that political and social unrest could  jeopardize  the already  difficult
task of restoring  economic and  financial  stability.  Meanwhile,  the Japanese
economy had slipped back into a recession. The Japanese yen continued to fall as
investors lost  confidence in the Japanese  government's  ability to redress the
problems  underlying  the economy's  malaise.  The weakening  Japanese  economy,
together with the drop in the yen, was seen as accelerating  the entire region's
financial and economic  decline.  To make matters even more  alarming,  Russia's
financial difficulties intensified. Worries mounted that the financial crisis in
Asia was spreading and threatening to swamp other  countries.  The impact of the
Asian downturn on the U.S. economy became more visible as the U.S. trade deficit
widened and more and more American  companies  began to warn that their earnings
would fall far short of expectations.

Needless to say, these two theories -- an unstoppable  economy versus an economy
being dragged down by trouble overseas -- were somewhat mutually  exclusive.  It
is not too surprising that the market became quite rattled and began to trade in
a flat  range  with a high of 9200 and a low of  approximately  8600.  Stocks of
companies producing goods and services for the domestic economy fared well since
their earnings met or exceeded  expectations and,  therefore,  gained favor with
investors.  Investors  deserted  companies  whose  exposure  to Asia or to basic
commodities cut into earnings.  Thus, careful stock selection made a significant
difference and contributed to the strong performance of the Portfolios.

LOOKING AHEAD
Since the  situation  in Asia is likely to  remain  highly  uncertain,  investor
sentiment,  we believe,  will oscillate  between guarded  optimism and pessimism
and, as a result, the financial markets both here and abroad will continue to be
highly  volatile.   We  expect  economic   conditions  in  the  U.S.  to  remain
constructive,  but the rate of growth should slow in response to the weakness in
the manufacturing  sector.  Investors will continue to favor companies which are
able to produce solid earnings gains in a challenging economic  environment.  We
believe that high quality  growth  companies  with the ability to generate  high
levels of earnings should continue to perform well.

                                 Respectfully submitted,

                                 /s/David D. Alger

THE ALGER AMERICAN FUND
NOTES TO FINANCIAL STATEMENTS (UNAUDITED)

JUNE 30, 1998
================================================================================
NOTE 1--GENERAL:

The Alger  American  Fund (the  "Fund") is a  diversified,  open-end  registered
investment company organized as an unincorporated  business trust under the laws
of the  Commonwealth  of  Massachusetts.  The Fund operates as a series  company
currently issuing six series of shares of beneficial  interest:  American Growth
Portfolio,  American Small Capitalization Portfolio,  American Income and Growth
Portfolio,  American  Balanced  Portfolio,  American MidCap Growth Portfolio and
American  Leveraged  AllCap  Portfolio  (collectively  the  "Portfolios").   The
American Growth Portfolio,  American Small  Capitalization  Portfolio,  American
MidCap Growth Portfolio and American Leveraged AllCap Portfolio invest primarily
in equity  securities and each has an investment  objective of long-term capital
appreciation.  The American  Income and Growth  Portfolio's  primary  investment
objective is to provide a high level of dividend  income by investing  primarily
in  dividend-paying   equity  securities;   capital  appreciation  is  a  second
objective.  The American 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.  Shares of the  Portfolios are
available and are being marketed  exclusively  as a pooled  funding  vehicle for
qualified retirement plans and for life insurance companies writing all types of
variable annuity contracts and variable life insurance policies.

NOTE 2--SIGNIFICANT ACCOUNTING POLICIES:

(a) INVESTMENT  VALUATION:  Investments of the Portfolios are valued on each day
the New  York  Stock  Exchange  ("NYSE")  is open as of the  close  of the  NYSE
(normally 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 the 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
according to procedures  established  by the Board of Trustees to determine fair
value in good faith.

Securities  having a  remaining  maturity  of sixty  days or less are  valued at
amortized cost which approximates market value.

(b) SECURITY  TRANSACTIONS  AND INVESTMENT  INCOME:  Security  transactions  are
recorded on a trade date basis.  Resulting  receivables and payables are carried
at amounts which approximate fair value. Realized gains and losses from security
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.

(c) REPURCHASE AGREEMENTS:  The Portfolios enter into repurchase agreements with
approved  institutions,   primarily  U.S.  Government  securities  dealers.  The
repurchase agreements are collateralized by U.S. Government securities which are
verified by the investment manager as being either received and held in physical
possession  by the  custodian  or as having been  received by such  custodian in
book-entry form through the Federal Reserve  book-entry  system.  The investment
manager  monitors  the  value  of the  collateral  at the  time  the  repurchase
agreement is entered into and 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,  including an affiliate of the custodian,  provided that
the market value of 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 investment  manager ensures that the loan is  collateralized by
cash, letters of credit or U.S. Government securities that are maintained at all
times in an amount equal to at least 100 percent of the current  market value of
the loaned  securities.  At June 30, 1998,  the value of  securities  loaned and
collateral received thereon were as follows:

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

the Fund on the ex-dividend date.

Dividends from net investment income are declared and paid annually.


                                                                              25

expenses,  of the American  Growth  Portfolio  exceed 1.50%;  the American Small
Capitalization  Portfolio exceed 1.50%; the American Income and Growth Portfolio

Growth Portfolio exceed 1.50% and the American Leveraged AllCap Portfolio exceed
