                                        AFTER-TAX RETURNS

                                        Flip through any financial magazine and
                                        you'll see fund advertisements touting
                                        impressive returns. What these numbers
                                        don't show is the effect taxes have on
                                        an investment. Mutual funds are subject
                                        to taxes that can greatly influence the
                                        actual return you get to keep. To help
                                        you better understand the tax impact,
                                        the Acorn Family of Funds is now
                                        including after-tax performance for each
                                        of our funds.

</TABLE>

(1) PRETAX RETURNS

This is the same average annual total return we've shown for years. These pretax
numbers assume that all distributions you receive from the fund are reinvested
into new shares. This number does not consider the impact of the tax you pay on
income dividends or short- and long-term capital gains.

As an owner of mutual fund shares, you can be taxed two ways: on the earnings a
fund distributes to you while you own its shares and on the profits you make
when you sell or exchange shares.

(2) AFTER-TAX RETURNS

To determine after-tax total returns on shares that are owned, distributions are
treated as taxed at the maximum tax rate in effect at the time they were paid
with the balance reinvested. These rates are currently 39.6% for income and
short-term capital gain distributions and 20% for long-term capital gain
distributions. We use the highest tax rates to demonstrate the worst-case tax
scenario.

(3) AFTER-TAX W/REDEMPTION

After-tax returns with redemptions reflect the additional tax impact of long-
term gains or losses realized when fund shares are sold. These returns are taxed
at the maximum rate in effect at the time of sale (currently 20%) and assume
that you bought your shares at the beginning of the period.

Note: State and local taxes are not considered in the calculations.

(4) DETERMINING TAX EFFICIENCY

The tax efficiency percentage is calculated by dividing the after-tax return by
the pretax return. The closer to 100%, the more tax efficient your investment
is. For the 1-year period, Acorn International scored a 97.54% tax-efficiency
rating meaning the after-tax return was 97.54% of the pretax return. There are
many factors that affect tax efficiency. A fund's turnover rate, accounting
methods, cash flow and the types of securities held, all influence how tax-
friendly an investment is.

(5) THE BENCHMARK

How do Acorn's funds compare to their peers? To address that question, we are
including Morningstar category average performance. The returns provided by
Morningstar, Inc. are calculated in the same way as the fund calculations. As
you can see, 2.43% of Acorn International's return was lost to federal income
tax for the 1-year while its peer group lost an average of 2.2%. Morningstar
does not calculate after-tax w/ redemption or life of fund data so we have
placed "NA" for "not available" in those spaces.

The actual after-tax returns you achieve depend on your tax situation and your
own decision to sell or hold fund shares.

PAST PERFORMANCE DOES NOT GUARANTEE FUTURE RESULTS. The investment return and
principal value of an investment in any Acorn fund will fluctuate so that fund
shares, when redeemed, may be worth more or less than their original cost.

            In the 1999 Annual Report we retraced the route of Marco Polo in the
1280s. For those shareholders who think we started too early in the last
millennium, we are now leaping forward to 1720 London, home of the infamous
South Sea Bubble. The South Sea Bubble was the first impressive stock market
fiddle. The markets at that time were primitive by today's standards but were
driven by several very modern features: political clout, media hype, and the
power of stock options.

         The South Sea Company was incorporated in 1711 by act of Parliament
with two purposes. One was to form a monopoly on English trade with Spanish
America. The second was an ingenious synthesis of finance, commerce and foreign
policy by which (pound)9 million of government debt was assigned by Parliament
to the Company. The citizens who had owned the government bonds got stock in the
South Sea Company and the interest on the bonds was paid by the treasury to the
Company. The interest provided both working capital for Spanish American trade
and free cash flow to pay dividends to Company shareholders. The swap was
compulsory but the bondholders were eager to do it because (a) the dividend on
the stock was about equal to the bond interest they had given up and (b) they
turned in the bonds for stock valued at 100, but the stock was selling at a lot
more than 100, so an enticing capital gain beckoned.

         Why did the government grant this monopoly? Because a large part of the
export trading profits would go to King George I. The company's political clout
was so great that King George signed on as Governor of the Company in 1715 (that
office today might be called Honorary Chairman of the Board).

         The boom-bust stock move that went down in history as the South Sea
Bubble did not begin until the end of 1719, with the stock at 123, little
improved from its initial price of 100 in 1711. At that time, a second
government debt swap was proposed, this time for (pound)31 million, a prodigious
sum at that time. To induce the treasury to authorize the swap, the Company
agreed to drop the interest rate on the bonds. The interest rate would go down
from 6% to 4% after seven years, and the Company also agreed to make an
immediate payment to the treasury of (pound)7 million. Great plan, but in order
to convince bondholders to swap for stock, the Company had to show that the
dividend on the stock would be similar to the yield on the bonds. Since the
interest the Company would collect on their bond portfolio was going to drop
from 6% to 4% in a few years, the scheme was cash flow negative if the
bondholders swapped for stock at 100. If they could be persuaded to turn in
their bonds for stock valued at 300, they would be accepting a bad enough deal
that the rest of the shareholders would come out okay. The key to the scheme was
to keep the stock at a high price and rising enough to sucker the bondholders to
turn in safe government debt in return for the chance to make a quick killing in
the stock. How could they do it?

         Step one was public relations. Newspapers and pamphlets were recent
innovations in 1720, but the new technology attracted great authors including
Addison, Steele, Defoe, and Swift. The newspapers generally helped boost the
stock price, although the press could put out anti-Company blasts as well.

         Another tool was the use of "stock options" to influence politicians
and the aristocracy. In the March 20, 2000, Wall Street Journal, there was a
story about dot.com companies dealing options to actors who made commercials for
them, Whoopi Goldberg and William Shatner being two.


And Now A Word From The Duchess

         A company called World Online International copied the use of a Duchess
to hype stock. The company, a highly speculative Internet Service Provider from
Amsterdam, hired Sarah "Fergie" Ferguson, Duchess of York. On March 17, 2000,
World Online had an IPO at 43, underwritten by ABN Amro Rothschild, the leading
Dutch investment banker, and Goldman Sachs, the leading everywhere-else bank. As
the stock swooned after the IPO from 43 to 17 (April 14) in less than a month,
some investors who had only skimmed the prospectus at the time of the issue were
bemused to discover that the founder had sold two-thirds of her stock in a
private sale back in December./1/

The South Sea Company had already thought of that in 1720. The Company made
deals with numerous Dukes and Earls, 138 Members of Parliament, and most
helpfully, the Duchess of Kendal, mistress of King George. Whether Whoopi or the
Duchess would appreciate the comparison, they each acted as useful spokespersons
for the corporate sponsor.

         The "stock option" program was not quite as formal as it is in our
world. One of the problems that always plagued the South Sea Company was the
transfer agency bottleneck, as vigorous trading in the stock had to be processed
by a roomful of clerks scratching in big ledgers with quill pens. This method
was quite unable to keep up with trading volume./2/ The "option grants" were
entries by John Knight, cashier of the Company, in his private ledger known as
the Green Book. He simply wrote down the name of the recipient and the exercise
price of the stock, set to be somewhat above the market price at the time of the
grant. When the stock went above the exercise price, Knight delivered cash to
the lucky option holder. Since the winner had not put up any money or taken any
risk, this was a popular program. Of course, after the Bubble burst, the
Parliamentary Commission set up to investigate these events decided that the
payments received were no more than bribes.

         Lest we think of 1720 as an unsophisticated period, remember that the
gentlemen we see portrayed bewigged and stiffly-posed in portraits of the time
included Voltaire writing in France, Bach churning out cantatas in Leipzig, and
the smartest person ever, Isaac Newton, doing science in England. Newton was
asked for his opinion on the South Sea Company and replied, "I can calculate the
motions of the heavenly bodies, but not the madness of the people." Newton sold
out his South Sea stock on April 20, 1720, making a 100% profit of (pound)7,000,
a fortune at the time. Unfortunately, the world's smartest man then went right
back in, lost (pound)20,000, and could never bear to hear the South Sea Company
referred to for the rest of his life. This may have been the source of the Wall
Street proverb, "Never confuse brains with a bull market."

         How did the stock do? In December 1719, it started at 123. By early
April 1720, it was over 300, and at the end of April a public offering was done
at 400. In April, Parliament passed the South Sea Bill authorizing the Company
to exchange stock for government bonds, and also passed the Bubble Act. This
ruling was not intended to deflate "irrational exuberance" in South Sea stock;
to the contrary, the Bubble Act was designed to help the South Sea financing by
outlawing other companies from doing IPOs.

         The stock ran higher in May and peaked in early July above 900./3/ This
was a dramatic move over a seven-month period, but rather less than the rise of
many tech stocks between October 1999 and March 2000.

         What popped the Bubble? The news from France was a factor. A brilliant
Scot, John Law, forced to flee British soil because he had killed a man in a
duel over a woman, ended up in Paris. He started a French scheme quite similar
to the South Sea Company called the Mississippi Company, to trade with the
French-controlled but empty land that is now much of the United States. Also
funded by an equity-for-government-debt swap program, the Mississippi Company's
first foray to America founded the city of New Orleans but did not get further
upriver. Law's scheme collapsed in May 1720.

         Another grisly bit of bearish news reached London at that time - the
outbreak of bubonic plague in Marseilles. This epidemic closed ports for
quarantine, halting foreign trade.

         Whatever the trigger, by midsummer 1720 the Bubble had burst and the
South Sea stock plunged, although not to zero. It was still 200 in October 1720
and 160 in December. In fact, the Company lingered on for over a century before
being dissolved in 1854.

         The aftermath of the South Sea Company collapse was typically sour.
Parliament set up a committee to investigate and punish. The South Sea officials
and directors who had assets, and many did, returned the money - they were
simply sent to the Tower of London until they volunteered to make restitution.
John Knight, the man with the Green Book containing the list of Members of
Parliament and ministers option-bribed by the company, fled to Brabant in
Belgium where he was jailed. The information that he had would have been so
damaging to so many in England that the ministers finally decided to have the
Brabant authorities orchestrate an "escape" for Mr. Knight, who then lived in
France until he bribed his way back into England in 1742.

         The consequences of the South Sea Bubble were important but subtle.
There was no depression. Some people gained and others lost by speculation, but
the effect

Acorn Fund
         >In a Nutshell

[Photo here] [Photo here]

Acorn Fund was flat in the first quarter, up 0.4%. All our domestic funds
suffered the same plight: Our lower weighting in technology vs. our benchmark
indexes (see Page 1 for performance data) hurt relative performance. We are
highly selective in the tech arena. One of our favorite investment themes is to
invest downstream from technology in software, services, media, telecom and
biotech companies that are benefiting from tech but that aren't pure technology
or Internet plays. We believe these companies often offer excellent growth at
reasonable prices.

         Biotech stocks performed well in the quarter. Corvas International
delivered a 148% profit, Inhale Therapeutics inflated 75%, and Myriad Genetics
discovered a 30% gain. Acorn Twenty portfolio manager and health care analyst
John Park prescribed these companies to Acorn a few years ago when they were
cheap.

         As we all know, gasoline prices skyrocketed in the first quarter. While
this was bad for drivers, it was good for the oil and gas industry. Our energy
analyst Jason Selch hit pay dirt as Acorn pumped profits from higher energy
prices. Electric and gas distribution and trading company Dynegy surged and was
Acorn's largest dollar winner in the quarter. U.S. gas and oil producers Devon
and Equitable Resources also were up substantially.

         Bad news was punished severely. For example, Young Broadcasting won a
bidding war for a San Francisco TV station but promptly lost that station's
network affiliation, resulting in a cancellation of more than 60% of Young's
stock price. Carnival's bookings were slightly below target, causing its stock
to fall nearly 50%. Kronos and Sykes missed earnings estimates. While both
companies remain nicely profitable, their stocks halved.

         We sold half of our position in Japan's Softbank, an Internet service
provider and investment company. We prefer to hold our positions longer than
just 12-months but this stellar performer ran up so quickly that we cheerfully
took some of our profits off the table.

                                    Content
                                 Remains King

As part of our enduring "downstream from technology" theme, we look closely at
intellectual content stocks. For example, when cable television companies faced
risk from satellite broadcasters, we bought programmers such as Liberty Media,
successfully predicting that its content would benefit from additional
distribution. We extended our content preference into print media, and benefited
as Petersen and CMP Media were acquired. Our most recent success in content is
PRIMEDIA, which owns 170 focused consumer publications (ranging from Fly
Fisherman to Seventeen), 70 trade magazines (including Beef and Telephony) and
thousands of hours of educational videos (shown in schools and workplaces).
Under a new management team, the company is rapidly leveraging its content onto
the Internet. PRIMEDIA stock jumped 94% in the quarter and was Acorn's second
largest dollar winner.



Because of recent market volatility, short-term performance of the Fund or its
portfolio holdings may be different than stated as of 3/31/00.

Acorn International
     >In a Nutshell


[Photos here]

Acorn International rose 12.1% in the first quarter of the year, well ahead of
all its benchmarks and peer groups. Returns came from stock selection more than
country allocation. Our four best holdings, defined by contribution to return
over the quarter, were Li & Fung, Editoriale L'Espresso, Baltimore Plc., and
Amdocs, domiciled in Hong Kong, Italy, the UK and Israel, respectively. The
names that hurt performance the most this quarter were Star Cruises of
Singapore, Jafco and Trans Cosmos of Japan, Autogrill of Italy, and Atos of
France. These have all been successful holdings in the past, which gave back a
portion of their previous gains in profit taking.

     If country allocation does not explain the winners and losers this quarter,
can we look to sector exposure as a better predictor of performance? There is an
important change in the international investment environment. Companies are
compared increasingly to their peers across markets, as opposed to dissimilar
companies within their home market. What three of our top performers in the
quarter have in common is that they all rose on enthusiasm for technology, while
the two Japanese names that fell both reflected disillusionment with Internet-
related investments.

There is an important change in the international investment environment.
Companies are compared increasingly to their peers across markets, as opposed to
dissimiliar companies within their home market.

     We have to admit that we are not exactly sure what constitutes a technology
stock in today's world. A lot of pure "dot.com" companies are really old-
fashioned businesses distinguished only by the fact that they use the Internet
to distribute their goods or services. Some newly listed stocks have innovative
business models, but not much else in the way of operations. Other traditional
companies source a growing portion of their sales from end markets that did not
exist five years ago. Investors tend to paste hasty labels on groups and trade
them indiscriminately together, making their stock prices go up and down a lot
in a short period. Over the long term, however, fundamentals win out, and the
businesses that build value in the real economy, whatever they are called, do
the same for shareholders.

     Our philosophy at Acorn International is to buy quality companies with
solid fundamentals, strong market positions, and proven management. We focus on
small- to mid-sized companies, because they have the potential to grow for a
long time. We are neither market timers nor heavy traders. We do trim hot stocks
when the party gets too wild (which happened this past quarter), and add to them
after the crowds have left and prices return to sober levels (which we have
started to do this quarter). But the most important task we face is deciding
what to own in the first place. In that respect, we have a high degree of
conviction that the core companies in the portfolio will be the winners in
retrospect five years from now.

     From Audio
          to Stereo

The craze for media stocks over the last six months passed Audiofina by. Because
the ownership structure was complicated and the shares hard to buy, few
brokerage firms followed the company and management never appeared before
investors. What attracted us to this obscure Belgian holding company, however,
was its 50% ownership in a valuable TV and radio network. That obscurity ended
early in April when Pearson and Bertelsmann, two European media giants, agreed
to merge their TV and radio assets into Audiofina, making it the broadcast media
powerhouse of Europe with 22 channels, 18 radio stations, and over 120 million
viewers across 11 countries. When the stock lists in London later this year, we
believe its brand name, RTL, is poised to become a household name.

Because of recent market volatility, short-term performance of the Fund or its
portfolio holdings may be different than stated as of 3/31/00.

Acorn USA
     >In a Nutshell

[Photo here]

Acorn USA slipped -1.2% in the first quarter lagging the Russell 2000 Index's
7.1% return. As with our other domestic funds, we trailed the index due to our
lower weighting in technology stocks. We do own technology stocks but we steered
clear of tech names that were selling based on hot stock stories rather than
real earnings.

         Acorn USA's top two money-making stocks were Dynegy, an electricity and
gas marketing revolutionary that nearly doubled in price, and Gadzooks, a
popular teen clothing retailer. Of our technology names, MSI, a
telecommunication-based Internet service provider, was a winner. More reasonably
priced offshoot Internet plays like PRIMEDIA, a specialty magazine publisher and
web site developer; Aztec, an e-business consulting company; and Advanced
Lighting, a manufacturer of lighting products and fiber optics coatings, were up
between 75% and 230%.

         Despite some nice wins in the Fund, two significant portfolio holdings
disappointed last quarter. Sykes (help desk call centers for personal computer
users) dropped on revenue concerns that we believe will be temporary. Galileo
(telecommunication semiconductors) missed our revenue expectations. It was sold.

         Recent stock market cycles have become quite violent. We think a
sensible response is to build a portfolio of dynamic companies with strong,
multi-year growth prospects trading at good prices.

          Gadzooks
           Is "In"

Gadzooks is a teenage clothing retailer. Its stock plunged in 1998 when
teenagers suddenly deemed its duds uncool. Our retailing analyst, Ben Andrews,
smelled potential as the company reinvented its product line, but held off
buying until he was convinced the old, unpopular clothing lines were purged from
inventory and replaced with cool new brand-name stuff. Last March, nine months
after the stock's mini-crash, the Fund started buying shares, right at the cusp
of a sales surge and a tripling of the stock price. A year ago, Gadzooks bombed
out; today, as kids say, it's "da bomb."

This graph compares the results of $10,000 invested in Acorn USA on September 4,
1996 (the date Fund shares were first offered to the public), with all dividends
and capital gains reinvested, to the Russell 2000 Index. The Russell 2000 is
formed by taking the 3,000 largest U.S. companies and then eliminating the
largest 1,000, leaving a market capitalization-weighted index of 2,000 small
companies. The index is unmanaged and returns include reinvested dividends.

         PAST PERFORMANCE DOES NOT GUARANTEE FUTURE RESULTS. THE INVESTMENT

Acorn Foreign Forty
    >In a Nutshell

[Photos here]

Acorn Foreign Forty had a strong first quarter, up more than 15%. Fund
performance was well ahead of its benchmark indexes, which were down slightly
over the three months (see Page 1 for performance data). Our competitors, as
measured by Lipper, were also flat, up less than 1%.

         Strong stocks came from the media group. M6 Metropole TV, the French
television broadcaster we highlighted in last quarter's report, rose another
38%. We also saw larger gains in Italian publishers SEAT and L'Espresso. Cartoon
programmer Fox Kids Europe, and Luxembourg-based TV broadcaster Audiofina, were
strong in the quarter. Two of our big winners outside the media area were
telecommunication software companies: Amdocs in Israel and Comptel in Finland.

         There was no clear pattern to our losers, although both Peninsular &
Oriental and Star Cruises fell after U.S. cruise line Carnival bookings
increased less than analysts had hoped. We feel the cruise industry's truly
global approach makes it a good growth industry and that the recent rough waters
will soon calm.

         Acorn Foreign Forty, as well as the other Acorn funds, follows a buy
and hold investment strategy but sometimes circumstances make us vary from this
approach. For example, Softbank was expected to do well over a three- to
five-year period but it rose so quickly - increasing 20 fold in roughly 12
months - that we elected to take our profits and say sayonara to this stellar
performer. The proceeds from this sale were used to invest in technology stocks
trading at lower prices.

Acorn Foreign Forty had a strong first quarter, up more than 15%. Fund
performance was well ahead of its benchmark indexes ...

         Italians just say no
                to "pay as you go"

"Pay as you go" pension systems work well - provided you have more workers
paying in than retirees taking money out. In the U.S., we recognized more than a
decade ago that a critical imbalance would arise in our Social Security system
when baby boomers switched from "paying in" to "taking out." As a result,
Americans have been supplementing their social security by funding IRAs, 401(k)s
and other investment vehicles. While the process is well underway in the U.S.,
Italy is just getting started. The state "pay as you go" system was the only
game in town because private pensions were illegal until recently. With a green
light for pension investing, Italians are now pouring money into mutual funds.
Banca Fideuram, the leading Italian fund distributor and one of our top ten
holdings, is a beneficiary of this seismic change.

Acorn Twenty
         >In a Nutshell


[PHOTO HERE]


Acorn Twenty finished the quarter up 2.3%, behind the S&P 400's 12.7% gain and
in-line with the S&P 500's 2.3% return. Midcap growth stocks, particularly in
technology, had a very strong quarter and their contribution to the S&P 400
explains much of its outperformance. Investor enthusiasm for technology stocks
sailed to high valuation levels in the first quarter leaving value-oriented
stocks standing on the dock. We do hold technology names, but not as many as the
index. When many of these high-flying tech stocks dropped in April, however, our
Fund benefited from Acorn's more diversified investment approach.

     We had two stocks return more than 50% during the quarter. Dynegy rose
following its merger with electric utility Illinova. American Power Conversion,
dominant in the market for computer power systems, also saw strong gains. Other
winners: McLeod (telecommunication service provider) and Tektronix (analytical
instruments), now the fund's largest position, were up more than 40% for the
quarter.

     Insurance stocks continued to be weak. Progressive and UICI were both off
more than 20%. Comparing insurance stocks with other companies in our universe,
we decided to move out of that sector and redeploy funds into other ideas.

     Effective March 31, 2000, Mark Yost resigned from Wanger Asset Management
and no longer co-manages Acorn Twenty. Mark decided to start his own money
management firm. Looking forward, we remain excited about Acorn Twenty's future
as our team continues to look for great businesses selling at reasonable prices.


Investor enthusiasm for technology stocks sailed to high valuation levels in the
first quarter leaving value-oriented stocks standing on the dock.

     TEK: Selling the "bad"
             to increase value

Tektronix (TEK) manufactures test and measurement equipment used by Lucent,
Motorola, Rambus and others to design and test fiber optic systems, cell phones,
and memory chips. We analyzed TEK last year and concluded it was an attractively
valued, fast-growing, technology company. At that time, TEK's core business was
masked by its subsidiaries. In September, TEK began to sell off some of its
"bad" businesses to increase the value of its more profitable, core business. We
believe fiscal May 2000 earnings per share (eps) will include losses and low
profits from these sold businesses and we estimate eps to be between $1.20 and
$1.25. Now, unburdened by its divested businesses, TEK may earn between $2.20
and $2.25 in fiscal 2001. By looking beyond reported estimates, we purchased the
stock in October at a reasonable price. It has increased more than 40% since
then.

This graph compares the results of $10,000 invested in Acorn Twenty on November
23, 1998 (the date Fund shares were first offered to the public), with all
dividends and capital gains reinvested, to the S&P MidCap 400. 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 Index is unmanaged and returns include reinvested
dividends.

     PAST PERFORMANCE DOES NOT GUARANTEE FUTURE RESULTS. THE INVESTMENT RETURN
AND PRINCIPAL VALUE OF AN INVESTMENT IN THE FUND WILL FLUCTUATE SO THAT FUND
SHARES, WHEN REDEEMED, MAY BE WORTH MORE OR LESS THAN THEIR ORIGINAL COST.

   on balance was neutral. Stockbrokers, pejoratively called "stock-jobbers",
   were considered dishonest, foreign and an unpleasantly novel element in
   English society. Not surprisingly, the collapse of 1720 made their reputation
   even worse.

         Venture capital dried up after the fall due to distrust of any
   speculative venture, as well as IPOs being illegal thanks to the Bubble Act.
   The lack of new capital may have set back the onset of the Industrial
   Revolution by a few years, but factories and railroads showed up eventually.
   Great Britain continued on its path to top-nation status for the next 150
   years. Sir Isaac Newton's scientific fame was not diminished by his South Sea
   loss.

   Downwind From Technology

         High-tech companies of the early 1700s included the British East India
   Company, which had a trade monopoly with India, and a similarly named Dutch
   company trading exclusively in present-day Indonesia. These companies
   capitalized on a technological advantage of the time: naval superiority.
   Using this technology, the founders of the South Sea Company figured they
   could also profit from the overseas trading boom by incorporating a company
   to trade with Spanish America. Unfortunately, their business plan was
   seriously flawed. No one at the South Sea Company knew anything about America
   or trading, and Spanish authorities had no intention of letting Englishmen in
   on their trade monopoly. Only a few shiploads of English merchandise were
   sent to America and these items lost money. A stronger effort was made in the
   slave trade, with 45 shiploads of Africans carried between 1716 and 1718.
   This horrid scheme failed for a more horrid reason - too many slaves died in
   transit./4/

/1/ Wall Street Journal, April 14, 2000. None of our funds bought any of the
    stock at any time.

/2/ This method was also enormously difficult to unravel after the fall.

/3/ Most trading of the time was conducted in a coffeehouse that often saw a
    difference in stock price from one end of the room to the other. Because of
    this, it is difficult to nail down what the South Sea Company stock's high
    mark was but it is believed to have never traded above 1,000.
