Now that you have made it through the introduction, this book becomes more specific with its tests of the relative strength investment system and several trading systems. Each of the following chapters explains the concept of the study starting with what backtesting and methods I use, followed by the results and graphs of the studies themselves. In the investment section, the results include the best lookback period for relative price strength, the rank or ratio for portfolio addition or deletion, the minimum volume and price for an initial trade, and the percent stop that produces the best results in tests with data unknown to the study. I then cover derived relative strength system rules and modify them with a market-timing system to reduce the effects of a market decline. The final results are practical, robust stock picking investment systems and technical trading systems that should not tax the abilities of the individual investor and can be applied to any size portfolio.
