The Little Book of Bull Moves in Bear Markets: How to Keep Your Portfolio Up When the Market is Down (Little Books. Big Profits) by Peter Schiff, president of Euro Pacific Capital, is a very bearish book.
After predicting the recent market drop, Schiff now makes a very strong case for a very long bear market lasting years, with high inflation, continuing collapse of real estate, and rising commodity prices thrown in. He gives advice on what you can do to prepare for this onslaught of bad news. His recommendations include gold and stocks of strong foreign companies. He also recommends trying to get debt free, especially the variable rate credit cards and mortgages. One of the most interesting chapters is 'A Decade of Frugality'.
If you want a book that pulls no punches about the upcoming economic catastrophe, along with related advice, you should get Schiff's book The Little Book of Bull Moves in Bear Markets.
