We find that an investor can earn abnormal profits in the long-run using Forbes Platinum list of the 400 best big companies. Our trading strategy is based on results of an event study. When using the four-factor model of Carhart (1997), our results show that buying and holding the ten lowest ranked companies in a portfolio for 36 months post-publication would generate on average positive and statistically significant abnormal return of 22.74%. Consistent with the overreaction hypothesis of De Bondt and Thaler (1985), we find low ranked companies outperform high ranked companies in the long run.
