Too Many Cooks Spoil the Profits: Why Investment Clubs Dont Work
Abstract (Via Berkeley)
We report our analysis, using account data from a large discount brokerage firm, of the common stock investment performance of 166 investment clubs from February 1991 through January 1997. The average club tilted its common stock investment toward high-beta, small-cap growth stocks and turned over 65 percent of its portfolio annually. The average club lagged the performance of a broad-based market index and the performance of individual investors. Moreover, 60 percent of the clubs underperformed the index.
Introduction (Via Berkeley)
Investment clubs serve many useful functions: They encourage savings. They educate their members about financial markets. They foster friendships and social ties. They entertain. Unfortunately, their investments do not beat the market.
