Investing
or Betting?
At some time you have heard
investing being equated with gambling. While even the best
gamblers count on a certain amount of sure things, they know
there are always uncontrollable factors that ultimately
determine the outcome. Investing has its own set of crap shots,
particularly when investing for the short-term.
In the short run, the direction
and pace of economic activity often proves to be unpredictable.
Few, if any, investors or economists forecast the great speedup
in economic growth during the past decade, or the recession that
might be developing now.
Why this uncertainty? Basically
it is because so many variables influence swings in business
activity, and their relative impacts differ from one economic
period to the next. In contrast to the unpredictability of
short-term economic moves, the long-term outlook for business
activity is quite certain: gross domestic product will grow. So
no problem is forever.
The short-term pattern of
corporate profits is even more uncertain because of: changing
economic conditions (boom, recession, or something in between);
varying rates of overall inflation and swings in specific costs
(like energy, whose huge price increases are squeezing many
companies' earnings now); and competitive factors (such as the
worldwide overcapacity in the auto and personal computer
industries that has pushed down selling prices and profit
margins sharply, as demand for those products has slackened in a
slowing economy). One fact about individual companies'
performance is that there are good, bad, and indifferent
businesses, and firms in various industries usually perform
well, poorly, or so-so because of the basic characteristics of
their industries.
Forecasting earnings per share is
a crucial part of company analysis and even in these days of
"managed" earnings, that is hard to do accurately when
business conditions change, as they often do. In all but a few
very stable businesses, the conditions affecting profits can
shift from one quarter to the next, and one year to the next.
Investors did not see this when
the U.S. economy was experiencing unusually consistent, strong
growth. Forecasting near-term earnings was easy then, but as
less favorable business conditions have developed, predicting
quarterly earnings has returned to its normal degree of
difficulty and there have been lots of negative surprises. Most
of these have caused red faces for analysts and sharp stock
price declines. As with the general economy, many variables
influence short-term earnings and it is often impossible to
forecast the impact of all of them properly.
In another area of forecasting,
it has proven virtually impossible to pick the ultimate winners
in new businesses, especially in the fast-moving, high-risk
sectors. Most frequently, in fact, the early leaders have fallen
by the wayside.
Although economic forces are much
more powerful than political forces in our self-correcting free
market system, political factors can be influential at times.
But they are usually quite unpredictable.
It really is uncertain what
future political forces will influence the economy in the U.S.
or most other countries. Fortunately, in the U.S. most political
actions affect just a handful of individual industries, usually
through regulatory action (restrictions on drilling for oil and
gas, California's attempted deregulation of electric utilities,
prospective drug benefits for Medicare participants, etc.).
These can be important for a while for the affected industries,
but not significant for the overall corporate scene.
One area where government
(supposedly a non-political sector of government) plays an
important role is management of monetary policy by the Federal
Reserve Board. Changes in interest rates and the availability of
credit can have a major short-term impact on the economy and the
financial markets. Often the Fed's moves can be predicted
accurately, but there have been notable exceptions that
surprised investors.
Over the long run (measured in
decades), the stock market is usually very predictable. As has
been demonstrated many times, the long-term trend of stock
prices (both the overall market and most individual stocks) is
upward, in close parallel with the growth of earnings per share.
That is as certain as anything about equity investing, for the
simple reason that most companies' earnings do grow and the more
money a business earns, the more it is worth.
But in the short term, stock
prices are totally unpredictable, because shifts in investor
moods come quickly and they're very powerful, often carrying
stock prices to extremes. This is why focusing on valuation of
stocks is so crucial. Valuation measures investors' moods and
can thus tell us where a stock is located on the psychological
spectrum. That, in turn, indicates what the risk/reward
potential of the stock is -- but not where it is going tomorrow,
or next week, or even next year.
The real gamble of investing is
that random, totally unexpected event that pops out of the blue
and has, temporarily, a big impact on the stock market or a
sector of the market. Examples include the surge of inflation
from 3% to 13% in the 1970s (accompanied by similar increases in
interest rates), the spurt of interest rates to an unbelievable
10% in October 1987 (when inflation was only 3.5%), the Iraqi
invasion of Kuwait in 1990, the Asian financial collapse in
1996, the jump in energy prices, and now add the random
terrorist incident.
By definition, such events are
unpredictable, but because we know they will occur occasionally,
we should be prepared for them by prudent portfolio
construction. We should also recognize that these shocks will
not be fatal to the sensible investor; they just have to be
waited out.
When one looks at all the factors
influencing investment performance, it is clear that a great
many are unpredictable. But, in most cases, these relate to the
short term, while the predictable forces are generally long-term
in nature. And they have the greatest influence on ultimate
investment success. Many investors, especially inexperienced
ones, worry a lot about "confusing outlooks" and,
therefore, expend far too much energy in fruitless attempts to
forecast the unknown. Once we can admit what we do not know and
understand, we admit hat uncertainty is part of investing, we
can then focus our attention on what we do know. This will not
always provide the right answer, but it will increase our odds
of success, and it will avoid the anxiety that occurs when
forecasts of the unknown prove wrong.
