"The Intelligent Investor" by Benjamin Graham
Brian Gongol

Value investing is the concept that one should buy investments (like shares of stock) only when the price to be paid is less than the intrinsic value of the asset. And it appears to be one of those "either you get it or you don't" propositions. If the proposition sounds dull, or the promise of high rewards from other, more-glamorous investments is just too tempting, then it's probably not worth reading "The Intelligent Investor." But if the concept sounds alluring -- like buying a dollar bill from someone for 50 cents -- then Benjamin Graham's book is like a bible.
