Honestly I think this book is a little dated. The information is still useful, however there are easier ways to learn it. This book isn't written as clearly as it could be and sometimes felt dry. That being said, Graham still has profound insights about the market, and you can tell how much experience he has. In particular, Graham makes the observation that although rules and regulations change, the market looks the same. This is EXTREMELY telling of human psychology. In other word, people stay the same. People today have the same (Potential) biases as they had 100, 200, 1000 years ago. I'm still thinking about the significance of this thought but I know it is profound.
