There are many bears and many perma bears, but there are few valid methodologies to sell short. There are very few books on short selling. Essentially if you want to seriously develop a methodology for short selling you can look at the following three books.
How to Make Money Selling Stocks Short
Interestingly this book came in after the bear market was over. In earlier books William O'Neil was ambivalent towards shorting.
This is based on shorting growth stocks after they have peaked. All growth stock at some stage reach levels where it is difficult to sustain the high growth rates in sales or earnings, such stocks make good short sell candidates as they have run up a lot due to their earlier track record. However the tricky part is stocks top before the growth actually slows down. The book details various ways to short using chart patterns and moving averages.
The Art of Short Selling
This book by Kathryn F. Staley , is one of the best books on short selling. It takes a fundamental view of short selling and comprehensively covers the topic of short selling from valuation and forensic perspective. It details how fundamentals drive long term stock prices. Why stocks get overvalued and remain overvalued sometime for long periods. What kind of catalyst can signal good time to short. What to look for in fundamentals to uncover shorting opportunities.
Quality of Earnings
Earnings drive long term stock price. Companies use lot of tricks to dress up earnings. The best shorts are where there is some problem in companies earnings story. To detect such problems, one needs to understand earnings quality. This book is a bit technical but it is very good book on understanding what to look for in earnings quality.
These three books are some of the best resources if you are serious about developing a short selling strategy. Sold Short : Uncovering Deception in the Markets by Manuel Asensio is another book worth reading.
