Different Kinds of Suckers In the Market - "Reminiscences of a Stock Operator"

This is a rather interesting part where he describes different players in the market most of who are "suckers." Although, I think this really applies more to traders than long-term investors. Enjoy.

"I made up my mind to be wise and play carefully, conservatively. Everybody knew that the way to do that was to take profits and buy back your stocks on reactions. And that is precisely what I did, or rather what I tried to do; for I often took profits and waited for a reaction that never came. And I saw my stock go kiting up ten points more and I sitting there with my four-point profit safe in my conservative pocket. They say you never grow poor taking profits. No, you don't. But neither do you grow rich taking a four-point profit in a bull market.

About the time I discovered what a small percentage of what I should have made I was getting I discovered something else, and that is that suckers differ among themselves according to the degree of experience. The tyro knows nothing, and everybody, including himself, knows it. But the next, or second, grade thinks he knows a great deal and makes others feel that way too. He is the experienced sucker, who has studied not the market itself but a few remarks about the market made by a still higher grade of suckers. The second-grade sucker knows how to keep from losing his money in some of the ways that get the raw beginner. It is this semisucker rather than the 100 per cent article who is the real all-the-year-round support of the commission houses. He lasts about three and a half years on an average, as compared with a single season of from three to thirty weeks, which is the usual Wall Street life of a first offender. It is naturally the semisucker who is always quoting the famous trading aphorisms and the various rules of the game. He knows all the don'ts that ever fell from the oracular lips of the old stagers excepting the principal one, which is: Don't be a sucker!

This semisucker is the type that thinks he has cut his wisdom teeth because he loves to buy on declines. He waits for them. He measures his bargains by the number of points it has sold off from the top. In big bull markets the plain unadulterated sucker, utterly ignorant of rules and precedents, buys blindly because he hopes blindly. He makes most of the money until one of the healthy reactions takes it away from him at one fell swoop. But the Careful Mike sucker does what I did when I thought I was playing the game intelligently according to the intelligence of others."
