Building a portfolio of stocks is a little like assembling a baseball team. However, unlike a team of real baseball players, constructing a portfolio of stocks can mix low-priced single-A farm players with blue chip Hall of Fame players from the Majors. Billy Beane, the General Manager for the Oakland Athletics, was chronicled in Michael Lewis’ book, Moneyball. Beane creates an amazing proprietary system of building teams more cost-efficiently than his deep-pocketed counterparts by statistically identifying undervalued players with higher on-base and slugging percentages. According to Beane, traditional baseball scouts were overpaying for less relevant factors, such as speed (stolen bases) and hitting (batting percentage).
