Query: The Inefficient Stock Market, What Pays Off and Why

Ever since I finished my MBA in 1985, I have suspected that the stock market is volatile and inefficient. I have studied Markowitz, the CAPM, and other elegant mathemetical models of the market that indicate the market (ex. S&P 500) cannot be beaten. This book claims it can and I believe Haugen is really on to something big.I have been a non-financial scientific and technical analyst for a company doing business primarily with the defense department for over twenty years and found the analysis techniques presented in the book to be completely rational and apparently based on a very sound statistical approach.This is the most refreshing approach to reality investing I have yet read. I intend to read the other two books in the trilogy.If you want to break out of the Modern Portfolio Theory mold, read it.
