Do individual investors’ stock recommendations in online communities contain investment value?

Abstract

This paper investigates the investment value of individual investors’ stock recommendations within online communities. We find that aggregated recommendations contain no explicit investment value and that following these recommendations may have a negative impact on investment performance. Our results suggest that recommendations are mostly based on simple heuristics and concentrate on a small number of stocks. When restricting the set of recommendations to those made by the most experienced or successful recommenders, results marginally improve but still preclude profitable investment strategies. Experienced and successful recommenders seem more likely to avoid the most expensive pitfalls rather than actually exhibit superior investment performance.
