I just got back from a weeklong vacation, during which time I read "A Mathematician Plays the Stock Market", by John Allen Paulos, cover to cover. It is brand new. It doesn't give specific techniques for trading, but definitely gives a lot of different things to think about. I enjoyed it more than Fooled by Randomness. Make sure to read the whole thing because there are some interesting conclusions near the end. Has anyone else read this book yet?
