The best-performing managers are more strongly similar than the poorest-performing managers, who have low correlation with momentum. Investment performance of momentum strategies at the industry level is competitive, or between the top 10% and top 25% of funds in each period. The source and the persistence of these patterns compared to optimal asset allocation are cause for speculation.TOPICS: Portfolio construction, exchanges/markets/clearinghouses, mutual fund performance
