Short selling for the long term : how a combination of short and long positions leads to investing success

"This book describes the methods used by Joseph Parnes, President of Technomart, to obtain consistent returns in the stock market. Most investors fail to exceed the returns represented by the Standard and Poor's Stock Index, but Parnes often does using his investment philosophy. This book outlines his method of stock assessment, providing an understandable formula. If the formula tells a reader to buy a stock, then, as explained, there is a significant chance that stock will go up. If the formula tells a reader to short a stock, then the book shows how there is a significant chance that the stock will go down."
