Modern Portfolio Theory, or Poker With Polly


[PHOTO OF RALPH WANGER APPEARS HERE]

About 30 years ago, the hottest academic gathering in finance was the Center for
Research in Security Prices (CRSP) semi-annual meeting at the University of
Chicago. The director of CRSP was our own Jim Lorie, who ran CRSP and also made
many valuable contributions to modern finance theory. The beginning of all this
effort was a simple question that an officer at Merrill Lynch asked Jim: "If you
had owned a typical stock portfolio for a long time, how much money would you
have made?" There was no answer available. The Dow-Jones averages existed, but
they were (and are) calculated in such an old-fashioned way that they are
mathematically worthless. A young professor, Larry Fisher, took on the job of
developing good data on stock prices, which sounded no sweat - just look up the
prices in the old Wall Street Journal in the university library. It was a whole
lot harder than that. After many years of painstaking work, Fisher's team
produced data that is now the standard source for most work in financial
research.

Low-ball poker is ordered by a reverse lexicographic sort.

     One of the most important theories to come out of the work at Chicago and
other universities was the Capital Asset Pricing Model (CAPM). After a long list
of unrealistic assumptions, CAPM suggested that owning a bit of everything,
called the Market Portfolio, had a better risk/reward profile than more
concentrated portfolios. If that were so, an unmanaged, broad portfolio would be
a valuable asset, and so the idea of the Index Fund was born.

     One of the young scholars present was Bill Fouse, who understood financial
mathematics not only in theory but also in the real world, for he organized the
evening poker games at the CRSP meetings. Experts in mathematical statistics
make interesting poker players. In one game, one of the few female members of
the group sat in. Polly was a beginner at poker, so when the dealer called a
game of "High-Low," she asked Bill Fouse what constituted the winning hand for
"Low." Bill thought for a few seconds, and replied, "Simple enough. It is
ordered by a reverse lexicographic sort."

     "Fine," agreed Polly. That was exactly the information she needed to win
three of the next five hands. Who says advanced mathematics isn't practical?

     Despite his own poker-playing prowess, Bill Fouse took a day job. In 1971,
he created a pioneering index fund at the Wells-Fargo Bank, and then went to the
Mellon Bank and started their index fund department, so he has as good a claim
as anyone to be named "Father of the Index Fund." In March 1998, he presented a
paper at the Investment Company Institute's annual meeting in Washington, DC.
What does the Father of the Index Fund say now?

     "Based on my analysis, I believe the S&P 500 is likely to underperform the
broader market in the foreseeable future.

     "...My assertion was, and is, that the lower-risk, higher-liquidity large-
cap stocks should promise less total return to investors than higher-risk,
illiquid small-cap stocks.

     "As of March 1998, I expect large stocks to soon cease outperforming the
average stock. As a result, for some adjustment period (the next five years or
so), actively managed portfolios may outperform the S&P 500 by 50 percent or
more - which spells more trouble for the already sputtering institutional large-
cap core-index fund business."/1/

     If Bill Fouse says that his index fund will underperform actively managed
small-cap funds over the next five years, I can but bow to his wisdom and
experience. Nobody can predict the future, but Bill's idea is a good theory.
Small stocks continued to underperform for the six months from his March speech
through September, but in the last few weeks small-cap stocks have turned
upward.

Acorn Launches Two New Funds

This quarter, we are pleased to announce two additions to the Acorn Family of
Funds, Acorn Twenty and Acorn Foreign Forty. These funds will invest primarily
in the stocks of mid-cap companies -- those with market capitalizations of $1
billion to $10 billion. In October, we mailed information about Acorn Twenty and
Acorn Foreign Forty to all current shareholders. The funds will begin trading on
November 23.

     We've received a lot of phone calls since announcing Acorn Twenty and Acorn
Foreign Forty. Many of you have asked us why we are launching two new funds in
the midst of extreme market volatility. Some of you wonder why we're starting
mid-cap funds when our expertise is in small-caps. The answer lies in our
experience, which has taught us to follow two rules: (1) stick to what you know
and (2) listen to your customers.

     First, we know how to pick stocks. Over the past 28 years, our extensive
research has uncovered great stocks of great companies, some of which were too
large for our existing small-cap portfolios. Our analysts' stock-picking process
works just as well with mid-caps as it does with small-caps. (Remember that many
of the stocks currently in Acorn Fund were small-cap when we bought them, but
have grown to mid-cap size.) Acorn Twenty and Acorn Foreign Forty will offer
investors access to a select group of larger companies that exhibit the exact
same characteristics as our small-cap picks -- stocks with strong growth
potential, solid fundamentals, and a reasonable price.

     As far as the market volatility goes... we think that we may be starting
new funds at a time when great bargains are available. We invest with a long-
term objective for all of the Acorn funds, and Acorn Twenty and Acorn Foreign
Forty are no exception.

     We're excited about the launch of these funds, and hope you share in our
enthusiasm. If you need another copy of the prospectus or have any questions
about the new funds, call a shareholder services representative toll-free at 
1-800-9-ACORN-9 (1-800-922-6769).

MEET THE TRUSTEES This quarter, we are pleased to introduce two of the most
senior members of the Acorn board of trustees: James H. Lorie and David C.
Kleinman.

     Jim Lorie is Vice Chairman of Acorn's board of trustees, and has served
Acorn shareholders since 1970. As noted on page 2, Mr. Lorie was the founder and
first director of the University of Chicago's Center for Research in Securities
Prices. He served as associate dean for U of C' s Graduate School of Business,
and was instrumental in developing a long-term plan for its success -- what came
to be called The Chicago Approach to Business Education. The approach was the
first serious alternative to Harvard's case study model, and it is now the
dominant approach to business education. The University of Chicago is now rated
as one of the top business schools in the world. Six members of the Acorn
investment team are Chicago MBA's. Today, Mr. Lorie is a professor emeritus.

     David Kleinman is also affiliated with the University of Chicago. He is
currently adjunct professor of strategic management at the Graduate School of
Business, and has taught finance, strategy and business policy. Mr. Kleinman has
participated as a trustee for the Acorn funds since 1972, and also serves on
several other corporate boards and is a private business consultant. His
experience includes work in the Finance Staff at the Ford Motor Company, where
he was responsible for oversight and management of the investment managers of
the Company's pension funds.

Acorn USA
    In a Nutshell

[PHOTO OF ROBERT A. MOHN APPEARS HERE]

Last quarter stocks got a good ol' whupping. Acorn USA dropped 19.3%, just less
than the Lipper Small-Cap Fund Average's 21.5% plunge. Year-to-date, the Lipper
average is down 16.5% while Acorn USA is down only 8.2%, a semi-heroic result in
small-cap land. Of course, it's also 8.2% less than you could have earned in a
piggybank.

     Fear finally dethroned Greed last quarter. Scary stories about credit
crunches, Asia's crumbling economy, and the beheading of hedge fund nobles
snapped investors out of their bull market trance. The herd deserted stocks and
stampeded into safer hiding places (like piggybanks).

     Our worst stocks were our heavy debtors. Debt adds risk, and risk was a
major turn-off. Magellan, Host Marriott, and RCN all have debt dependencies,
which gave their stocks the shakes. Each dropped 30-60%. Centennial Cellular and
Cable Michigan received takeover bids this year, but wilted along with the high-
yield bond market they need to tap to obtain takeout financing. High-yield bonds
aren't selling these days. Investors have turned into a bunch of teetotalers who
buy bonds from only the soberest of credits. For the moment, our takeover duo
doesn't qualify.

     Small stocks are sinking under a torrent of tax-loss selling. Mutual funds
desperately want to take tax losses by October 31 (the day most mutual funds
have to measure realized gains and losses for tax purposes). But tax deferral
just isn't worth what it used to be, given today's low capital gains tax rates
and low interest rates. Still, tax-motivated selling can make a lot of sense...
for the buyer. Taxophobes have a perverse instinct to sell stocks at the lowest
possible price in order to realize the greatest possible tax loss. We're taking
the other side of those trades, buying some of our favorite stocks at firesale
prices. Here's to a happy new (tax) year!

Dynamic Duo

Kronos and Micros are our tech twins. Both have dominant shares of budding
technology markets (and very Homeric names). Both take common business gadgets
(timeclocks for Kronos, cash registers for Micros) and stuff them with computer
chips and proprietary software to create "smarter" devices that link to their
customers' information management systems (manufacturers for Kronos,
restauranteurs for Micros). Both are ensconced in protected tech niches, growing
briskly, valued moderately and deserving of our top 12 list.

Acorn Fund
    In a Nutshell

[PHOTOS OF RALPH WANGER AND CHARLES P. McQUAID APPEARS HERE]

On August 17, Russia defaulted, triggering a worldwide market panic. Long Term
Capital Management, an over-leveraged hedge fund, failed, requiring a $3.5
billion bailout on September 23. Four days later, Japan Leasing Corporation
filed for bankruptcy, becoming Japan's biggest financial failure in 50 years.
Realizing the risk, investors cut off low-grade lending. Prices for "junk bonds"
and financial service companies plunged, and other stocks dropped in sympathy.

     Acorn Fund lost 19.5% in the quarter, not quite as bad as the Lipper Small-
Cap Funds Index (-21.4%) and the Russell 2000 (-20.2%). As shown on page 7,
large-caps fared better over the same period.

     A number of Acorn's stocks got nailed this quarter. Windmere, IFR Systems
and Metal Management all collapsed about 80% due to weak sales and the Asian
crisis. InfoUSA dropped 59% on an earnings shortfall and management turmoil.
Thermo Instruments and Thermo Electron cooled 58% and 56%, respectively, on a
drop in their Asian sales. Giga Information, Larscom, and Dunn Computer fell 60-
70% each. These were mostly small positions to start with (even smaller now), so
the total portfolio was down a lot less.

     Acorn's technology stocks held up relatively well. American Power
Conversion and Solectron beat EPS estimates, powering respective stock gains of
26% and 14%. Compuware gained another 15%.

     Financial panics, like emotional panics, are severe but usually short-
lived. By late October, the gloom lifted. The Fed reduced interest rates and
indicated that it will provide liquidity. Small-cap stocks have begun to
recover, and have become excellent values relative to large-caps. The corporate
world apparently agrees, resulting in takeovers of our stocks. Zeigler Coal,
Altron, Mecklermedia, Fred Meyer, and HBO & Company agreed to sell out.

We first bought Solectron in 1989, when its market cap was just $35 million.
This electronics outsourcing company had a superior track record, but had a
cheap stock because public competitors had erratic results. Since then, the
trend to outsourcing accelerated. Solectron bought a number of original
equipment manufacturing plants, accompanied with supply contracts. Solectron's
worldwide capabilities are a major advantage in serving multinational customers.
Since our first purchase, Solectron's sales are up 4000% and its stock is up
6400%.

The S&P 500 is a broad market-weighted average of U.S. blue-chip companies. The
Russell 2000 is formed by taking the 3,000 largest companies and then
eliminating the largest 1,000 leaving a market capitalization-weighted index of
2,000 small companies. The Lipper Small-Cap Funds Index measures the performance
of the 30 largest U.S. small-cap funds tracked by Lipper. The S&P MidCap 400 is
a market value-weighted index of 400 stocks that are in the next tier down from
the S&P 500. The Dow Jones Industrial Average includes 30 large companies. All
indexes are unmanaged and returns include reinvested dividends.

Acorn International
    In a Nutshell

[PHOTO OF LEAH JOY ZELL APPEARS HERE]

The Brazilians call August Mes do Cachorro Louco, or month of the crazy dog. We
have had an entire quarter of crazy dog behavior in world markets. As investors
around the globe turned away from risk, the prices of equities and all but the
highest quality credits crashed.

     The real world has not changed nearly so much as prices might suggest. The
problems of Asia and the parlous state of Russian finances were both well-known
in July. What changed was the psychology of financial markets. The large losses
on Russian government bonds caused investors in those markets to sell their
holdings elsewhere to pay off creditors. The subsequent wave of liquidations
triggered sharp markdowns on all types of financial assets and shook investor
confidence worldwide.

     The financial turmoil is now forcing policymakers from Tokyo to Brazil to
confront and deal with long-standing unresolved issues. Interest rates are
coming down globally. Both of these developments are good for equities long-
term. In the future, we will likely remember this volatility as positive.
Excesses were wrung out of the system and new initiatives adopted, leaving world
economies more resilient to crisis in their wake.

     The Acorn International portfolio is leaner and cleaner than it was a year
ago, having been repeatedly tested in a tough environment. Our relative
performance remains solid. We have plenty of cash to give us buying power in the
downdrafts. Valuations have improved dramatically and markets are rebounding.
With many quality company stocks on sale, we expect to do a lot of shopping
between now and year-end. What you should not expect is a large tax bill in
December, because we have made a concerted effort to avoid one.

With best wishes from our entire team,

What do scientists at the European Space Agency, air traffic controllers in
Australia, and toll booth operators in Hong Kong have in common? They all work
for Serco, a facilities management company that handles complex logistical tasks
on long-term contract for governments and blue-chip corporations worldwide. The
large demand for such services has driven company sales and profits in excess of
25% over the last five years. Serco has been in our portfolio since 1994, over
which time its share price has more than tripled.
