Before Jim Rogers hit the road to write his bestselling books Investment Biker and Adventure Capitalist, he was one of the world’s most successful investors. He cofounded the Quantum Fund and made so much money that he never needed to work again. Yet despite his success, Rogers has never written a book of practical investment advice–until now.

In language that is both colorful and accessible, but Rogers explains why the world of commodity investing can be one of the simplest of all–and how commodities are the bases by which investors can value companies, markets, and whole economies. To be a truly great investor is to know something about commodities.
