This book is much technical than The Intelligent Investor and it was written before The Intelligent Investor, thus it was very difficult for me to read this one. But the latest (sixth) edition is really good. I have started reading the third edition and I had to abandon it after reading 70% of the book becuase many of the topics were outdated and there were no comments to modern times. So if you want to read this book, get the latest edition; don't be me and don't waste your time :P
