Glad to see 'When Genius Failed' (Lowenstein) here. I felt like it was the perfect sequel to 'Liar's Poker', Michael Lewis' first book on his life as a bond trader at Salomon Brothers in the 1980's. I feel like these two books are valuable, even essential, background for studying finance as practiced by Wall Street.
Reminisces of a stock operator
When genius failed
Unconventional success
And generally just read financial news and follow markets until you develop a sense for spotting BS.
