that don't work

Pick
A Method
If you've ever gone to the library
and browsed the business section, then you've noticed how many
people have written books on investing. It's a popular topic
to write about. It's apparent that many investors, after having
experienced some level of success, have felt compelled to write
a book about their methods. Among the authors are mutual fund
managers, wall street analysts, day traders, long term investors,
stock brokers, newsletter writers, professors, and investment
journal editors.
The authors tout
all kinds of methods and formulas that have worked for them
- buying stocks with low price/earnings ratios, buying stocks
with high price and earnings momentum, small stocks, big stocks,
medium size stocks, low price stocks, technology stocks, insider
trading, technical analysis (chart reading), and fundamental
analysis (analyzing company balance sheets and profit &
loss statements) - just to name a few.
Probably a few
of these methods have some merit, but over the long term, most
of these methods fall apart as soon as they are well known by
the general public. In fact, if a particular method has worked
for some time and a book is written about it, chances are that
it will soon cease to be profitable as more and more people
try to buy and sell the same stocks at the same time.
The
Rise And Fall Of Market Gurus
Throughout history, there
have been many people who have had such good luck with their
particular method of investing that they have come to be known
as “market gurus”. Market gurus come and go with regularity.
It all begins with a market professional who has a streak of
winning market calls over a period of years. Eventually, he
or she becomes a prominent media figure who is widely renowned
as a market guru - one who's every word hits the news wires
like a lightning bolt, sometimes even capable of moving the
markets single-handedly. Eventually, most of these market gurus
run into a string of bad market calls and slowly fade away into
anonymity. Others crash and burn after a spectacular doomsday
prediction proves to be false. Now this isn’t to say that none
of the market gurus deserve their title, but the question is,
how can you know which of these market experts are truly gifted,
and which are just lucky.
How
Many Monkeys Does It Take To Beat The Market?
Consider what you would expect from
a purely statistical viewpoint. Let's define a "market
guru" as someone who has beaten the S&P 500 stock index
for 5 years in a row. If we were to start off with 1000 monkeys
who picked stocks by throwing darts at the stock listings in
the business section of any local paper, how many of the monkeys
could be classified as "market gurus" after 5 years.
Well, let's assume that in any given year, about 50% of the
monkeys perform better than the S&P 500 stock index. This
is more or less reasonable since the S&P 500 stock index
is supposed to be representative of the average stock. After
the first year, that leaves 500 monkeys who are candidates for
the market guru club. As the table below indicates, if you continue
on through the fifth year, you're left with 32 monkeys who have
been consistent market beaters.

| 3 |
125 |
| 4 |
63 |
| 5 |
32 |
But,
would you invest your money with one of these 32 monkeys? Of
course not! Consider a historical fact - studies have shown
that, on average, investing your money with a mutual fund that
has been a great performer in the past is no more profitable
than investing in a mutual fund that has only had average performance
in the past. Why is this? It’s simply the same statistical phenomenon
that was applied to the monkeys above. Some fund managers got
lucky!
Now
don't misunderstand the point being made here. Market analysts
and mutual fund managers are certainly smarter than monkeys.
But perhaps their intelligence is working against them. Consider
another historical fact - on average, only about 15% of mutual
fund managers are able to beat the S&P 500 stock index in
any given year. Think about this - 5 out of 6 of these managers
could not buy and sell stocks for their mutual fund portfolios
that could beat a basket of average stocks. What's more, according
to The Hulbert Financial Digest, which monitors the performance
of investment advisory newsletters, as of January 1999, only
4.4% of the investment newsletters have beaten the S&P 500
over the last 5 years. That means that 19 out of 20 of these
investment advisors could not pick stocks that performed better
than average!
How
can this be? These are the professionals. This is their full
time job. They watch the market each day as news unfolds. They
are continually talking to the management of companies that
they are investing in. They know the insiders. Why can't they
beat the market? Well, for one thing, the news they listen to
is a lagging indicator. How else can you explain the fact that
stock prices often begin to move before news breaks. And once
the news breaks, the stock price moves so fast that the average
investor has no chance to act on it.
How
To Beat The Professionals
Ask yourself this question. How
can you hope to do better than the professionals? What resources
do you have that the experts don't? They have the news even
before the average investor does. The answer is that in
order to beat the market you must use methods better than those
used by the experts! The methods that you must use should not
be dependent on late breaking news stories. They should not
be based on advice from the experts or on advice from the managements
of publicly traded companies. To be a successful investor, the
method you use must be able to see the hidden causes and effects
that will make people feel compelled to buy stocks - before
they buy them. This is exactly what our neural network
computer programs are designed to do.
