Leon S. Robertson, Ph.D. -- Books and backgrpund information:

This page provides links to Leon Robertson's publications and free downloads of the 4th edition of Injury Epidemiology and computer programs for stock analyses. The Foreword of Leon Robertson's book on the stock market: "There are dozens of books on the stock market. So why write another? Because I have found that most popular stock-trading rules of thumb and systems touted in books, magazines and websites are unreliable when tested scientifically. The tales of their effectiveness are myths. If you are investing based on the recommendations of one or more of the myth makers, you are at risk of underperformance at best and big losses at worst. Chapters 1-9 deal with the myths and how they were exposed. To optimize returns, investors need to know how to evaluate trading systems by comparing average annual percentages return (APR). In this book, readers learn how to calibrate buy and sell limits for trading to optimize APR. Using free Internet downloads of decades of equity prices, the limits are developed using half of a series of prices and then are tested for their reliability using the other half of the series. Using these methods, I have discovered a new stock trading system that doubles investment returns on relatively safe exchange traded funds (ETFs). Anyone who can operate a hand calculator can profit from use of the system. Readers who are a bit more computer savvy learn to test their own ideas based on scientific methods using free software downloaded from the Internet. Chapters 10-12 reveal the new trading system and how to use free computer programs to develop your own." To use the new systems, the data must be updated and the programs run to see which equities are a buy.
