Abstract

For the past nine years the Globe and Mail (Canada's oldest national daily) newspaper has held an annual stock picking contest. In 2002, 2003, and then again in 2004, a finance professor won this contest. Motivated and inspired by the contest, this article shows that a rational player can increase the odds of winning an investment contest to a 50/50 chance by selecting a stock that (1) is highly volatile, and (2) negatively correlated with the other selections, or (3) exhibits a negative empirical beta. We conclude by arguing that picking stocks to win an investment game or contest is quite different from selecting securities for a personal investment portfolio.
