There are many persons who, although knowing a great deal about the
stock market, do not realize that the reason why they cannot “beat” it,
is that they know too little about themselves. There are others who
know their limitations well enough to let this monster problem alone.
As it is important that one should learn to swim before plunging into
deep water, so it is well to know some of the dangers of the stock
market before delving into it.
It is not the purpose of this book to dissuade anyone from buying and
selling securities, but merely to point out some of the stumbling
blocks and handicapping influences that speculators, and even
investors, are sure to encounter.
