Abstract:     
We document that stocks with the strongest prior 12-month returns experience a significant average market-adjusted return of 1.58 percent during the five trading days before their earnings announcements and a significant average market-adjusted return of 1.86 percent in the five trading days afterward. These returns remain significant even after accounting for transactions costs. We empirically test two possible explanations for these anomalous returns. The first is that unexpectedly positive news hits the market over the few days prior to these firms' earnings announcements, and that unexpectedly negative news comes out just afterwards. The second possibility is that stocks with sharp run-ups tend to attract individual investors' attention, and investment dollars, particularly before their earnings announcements. We do not find evidence for an information-based explanation; however, our analysis suggests the possibility that the trading decisions of individual investors are at least partly responsible for the return pattern we observe.
