I give Shipman the credit for tackling the history of several investment booms and smoothly explaining the phsycology and human factor behind hype. However, I don't see the book relevant when it comes learning about investing in commodities. I wish it explained more how to study the fundamental of each one instead of including an elementary schoolbook paragraph. If you have an investment background and know a bit about commodities, this is not for you. I would have rated the book higher had it been relevant to commodities as it claimed it was.
