One doesn't have to cheat in order to win.

There is gobs of public info out there and it is my sense that not all of that info gets to the market instantaneously nor efficiently (flying in the face of some of the tenants of the efficient market hypothesis ).

Firn has rightly recommended Benjamin Graham's book the Intelligent Investor as worth a read. I second his recommendation...Mr. Market sometimes drops by with some craaazzzyyy pricing on stocks...enough value that one can later sell those same stocks and cover one's beer and pretzels expenses for the year.
