.Self-flagellating nonsense by someone who understands math, but not markets. (He bought WCOM @ 36 and then averaged down on the position, throwing good money after bad, for 3 more years!) In other words, a confessional by yet another clueless academic enamored of the MPT/Behavioral Finance crowd, but who lacks the market savvy or just plain common sense to make proper use of those theories (which address institutional-level concerns, but say little of relevance to individual investors.)Far better books are:Nassim Taleb, Fooled by Randomness: the Hidden Role of Chance in the Markets and in Life.Justin Mamis, The Nature of Risk: Stock Market Survival & the Meaning of Life
