It is not always easy to understand the very complex structure of a financial market. Albert Einstein once said that one should present things as simply as possible - but not any simpler.

Can index investors expect to achieve index returns in the long run? Does technical analysis of securities make sense? Should insiders be excluded from the market? Why is a good financial analyst at a disadvantage compared to a bad one? Why do stock market books usually assume that everyone can perform better than everyone else? And what does the dog have to do with it? The book concludes with eight concrete and very practical pieces of advice. They do not claim to be better than the others.
