Biaggio, I don't mind one bit that you posted those scans, that's why they are there after all.
I read (briefly) some of the comments here on Ben Graham's interview. What he is saying is partly true. In B.G.'s early years, finding FCC filings that show a company holds $xx in treasuries wouldn't have been disclosed nor would these assets have showed up in the price. In the interview, he was implying that most people would not be able to do as will as he did by just digging through the basic numbers within financial statements. He wasn't saying that the playing field is level. Also, as suggested by someone already, Graham was bored by investing and wasn't interested in it late in life.
General comments are almost always taken out of context and I am certain that this is the case with this particular question. If they would have continued in greater detail we would not be having this conversation. Moreover, does anyone need proof that systematically high returns are impossible to come by or otherwise the consequence of pure luck?
