A rewarding read, basically explaining the relations between markets. The basic ideas of the book are:
1. If dollar goes down, commodity price will go up as a buffer for inflation, which drives up interest rate, lowers bond price, and lowers stock price. It's not that simple but that's the basic relationship.
2. Commodity index can be used to predict stock market movements (using the CRB Index/bond prices ratio) and reduce portfolio risk due to low correlation with bond and stock prices.
However, it's an old book, most of the cases involve the 1982-90 prices, and I would be very interested to study how this kind of intermarket correlation perform beyond that time frame.
