The Stock Investor Pro program currently contains two screens based on William O’Neil’s CAN SLIM approach. The first screen, listed as *O’Neil (CANSLIM) in SI Pro, is based on William O’Neil’s investing methodology outlined in the second edition of his book, “How to Make Money in Stocks.” The second screen, called *O’Neil (CANSLIM Revised), was updated to reflect the third edition of the book. Though both screens have enjoyed strong price performance over our backtesting period, AAII’s original O’Neil CAN SLIM really took off and has been one of our top-performing screens from 1998 through 2012. Recently, however, the screen has produced very few passing companies, making it increasingly difficult to utilize this screen in a balanced investing strategy.
