I am not quite sure who is supposed to read this book. I am about to finish my M.Sc (Industrial management and engineering) and almost everything (98%) in this book was known to me.Regarding all the errors, I stopped marking them at about the 20th page. It is really terrible how there can be so many factual errors in one book (by far the worst book I have seen at least). E.g. the part on CAPM where it says that beta must be a nonnegative number.Please do not buy this book, at least not until the second edition has come out!
