The Art of Short Selling, by Kathryn Staley, is by no means about short selling. If I had to sum it up in a few words, I would say the book is focused on hardcore fundamental analysis. It points all readers in the direction of discovering and analysing fundamental problems with a company. The book clearly states that one should never short a good company with temporary issues or just because a company seems overpriced.
There is no mention of technical analysis, trends or volume. The true method of short selling described is based on an extremely detailed fundamental analysis, which is why I immediately purchased the book. The book describes everything that enterprising investors should do.
