Any discussion of Graham & Dodd's "Security Analysis" sure brings up memories from long ago. In the late 60's I was a young engineer with a little extra money to invest. Only I didn't know a thing about investing ... nada, zilch. So, I took a night class in investing at a nearby Jr College. Our textbook was the 4th edition of "Security Analysis" by Graham and Dodd.
The best part of the class, as I now only dimly remember, was not the book, but the instructor. He was patient, gave good explanations, and made the class interesting. Frankly, I remember the book as rather dry. I suspect, if I were to take it again today, it would likely be a lot more interesting. Never-the-less, I would not recommend the book for a beginner, at least not without a good instructor.
IMO, the best book written by Ben Graham is "The Intelligent Investor". It may be the best book on investing ever written, and this is not just my opinion, Warren Buffet agrees with me :-). BTW, if anyone decides to read "The Intelligent Investor", my recommendation is to obtain an older edition, i.e., any edition except the latest revised edition which is annotated by Jason Zweig. IMO, Zweig is a devotee of Modern Portfolio Theory and tends to annotate (reinterpret) Graham's book in modern terms (MPT & efficient markets). IMO, Graham must be rolling over in his grave.
