| Magical
Run or a Bunch of Hype?

Business Week is a respected bastion of the financial media.
Like much of the mainstream media, the magazine has a penchant
for publicizing trading successes. In its July 24th issue, BW
printed a 4-page analysis of "Inside Wall Street" columnist Gene
Marcial's stock picks for 1999. The article concluded that columnist
Marcial had a "very good '99" and called his stock-picking results
"impressive" and "sensational" for last year.
The article presented several pages of numbers supposedly showing
Marcial's weekly 1999 stock tips "trouncing" several indexes -
the Dow Jones Industrial Average (DJIA), Standard and Poors 500
Index (S&P 500) - and slightly trailing the Nasdaq Composite Index
(Nasdaq). Business Week measured the price performance of each
stock recommended in Marcial's column during 1999 and compared
price performance against the S&P 500, DJIA, Russell 2000 and
Nasdaq benchmarks. Price performance was measured against these
indexes one day after the column was printed as well as 1 month,
3 months and 6 months after publication of the stock tips.
Business Week eagerly reported that Marcial's picks were up an
average 8.8% the day after they appeared in print in 1999. This
compared to an average daily increase of only .5% in the S&P 500
index in 1999. Of course Marcial's picks jumped the day after
publication! Day traders hoping to make a quick buck bought his
popular picks and gave his recommendations a quick boost the day
after they were released to the public. Whenever a brokerage firm
releases a buy recommendation on a stock or Joe Kernan broadcasts
positive comments about a stock on CNBC, hype-reactions happen.
The short-term momentum traders react and "pump" the recommended
stock's price higher. Later (a few minutes, a few hours, a few
days), the day-traders "dump" the stock and long-term investors
or inexperienced day-traders who get sucked into this game lose
money - sometimes lots of money.
It's very interesting that this comment appears at the end of
each Marcial column: "Watch for Gene Marcial's 'Inside Wall Street'
column every Tuesday afternoon at www.businessweek.com/today.htm".
This is a clear signal and open invitation to day traders to pump
up his stock picks.
Let's take a closer look at Business Week's claim that stock-picker
Marcial "trounced" most indexes and slightly trailed the Nasdaq
index in 1999.
When comparing the price performance of a group of stocks to
a benchmark index, it's important to compare apples to apples
and oranges to oranges. In other words, when you take a look at
the 155 stocks that Gene Marcial recommended in 1999, it's important
to figure out the major types of stocks within the group of 155
and to select a benchmark index that makes sense in measuring
price performance.
For example, 85 (or 55%) of Marcial's 155 picks for 1999 trade
on the Nasdaq and American stock exchanges and are predominantly
small-cap tech stocks. The other 70 picks (45%) trade on the New
York Stock Exchange. Calculating an expected rate of return for
the Marcial picks for 1999 using the Nasdaq and the New York Stock
Exchange Composite Indexes (weighted 55% Nasdaq and 45% NYSE Composite),
these 155 stocks should have increased in price an average of
51%.
However, Business Week reports an increase of only 26% for Marcial's
1999 stock selections, a significant underperformance compared
to the 51% expected rate of return if the correct benchmark indexes
are taken into account.
Suddenly, Marcial's 1999 stock tips don't look so hot.
Something else to think about: nearly half these 1999 picks were
priced under $15 per share; 33% (one-third) were priced below
$10 per share. Low-priced stocks (especially shares priced under
$10) are often considered "penny stocks" and carry heavy risk
and are volatile (they move up and down in price a lot, creating
churning stomachs for long-term investors). "Beta" (a measure
of volatility for a stock's price, anything above the number 1.50
is considered super-volatile) was examined for Marcial's picks
showing 18% with Beta measurements above 1.50. Another 12% of
his picks have "N/A" listed in the Beta column, which often means
the Beta number is so astronomically high (it approaches infinity),
it isn't listed. In down-to-earth practical terms, this means
an investor can wake up thinking he owns a stock worth $15 and
after just one day of wild trading, the stock can shoot up (or
down) huge percentages of 50% or more, settling at $29 (or $1).
In rethinking the Business Week article, why would an investor
buy Marcial's stock tips? Hot stock tips usually burn the investor
over the long haul. Consider buying an index fund based on the
underlying benchmark index (such as the Nasdaq or NYSE composite
indexes) for good, long-term price performance without the heavy
burden of risk from over-hyped stock tips.
