Query: A Mathematician Becomes Emotional

I had hoped this book would show how mathematics can be applied to the stock market, but this it does not! Instead, the reader comes away with the insight that also mathematicians can become emotional and therefore commit the usual mistakes in investing activities. Big deal! The chapter on technical analysis was a disaster. I am far from convinced that any technical analysis can make profits consistenly, but I know enough about different methods to realize that the author has little knowledge about the subject.I rate it two stars because of the humour and self-critique it entails. Here, the author shares his shortcomings with the reader, and we can all smile in recognition of our own follies.After all, the author does confess that he wrote the book to make some money to cover his losses in the stock market.
