Quote from links:
Neiderhoffer, Richard Dennis, Jessie Livermore and many other giants of trading may be brilliant minds but they all suffered devastating losses.
I don't think Niederhoffer's name deserves to be alongside great traders like Dennis and Livermore... Taleb's Fooled by Randomness is a good book that explains why people like him ultimately lose big. IMO, Niederhoffer does not know and respect the limits of statistical inference, his writings remind me of the arrogance of ivy educated semi-quants/quants who have great knowledge but no wisdom to save them from the bullet that ultimately catches them in the back of their head.
