Book excerpt: Consistent with prior studies, this study shows that extremely negative and extremely positive earnings surprises in the fourth quarter have lower levels of persistence than those in the first through third fiscal quarters. Furthermore, extremely negative earnings surprises in the fourth fiscal quarter have lower levels of persistence than extremely positive earnings surprises in that quarter.Similar to the patterns of persistence, the post-earnings-announcement drift in prices is declining through the four quarters of the fiscal year, with the smallest drift occurring after the announcement of the fourth fiscal quarter. The drift after the fourth quarter is virtually nonexistent for extremely negative earnings surprises and smaller than extremely positive surprises, in line with the differential persistence of these surprises. The combined evidence in the study is consistent with investors who under-react to extreme earnings surprises because they seek further information. When the new information confirms the initial surprise, prices move in the same direction, creating a drift. The results of the study are robust to earnings surprises based on time-series properties of earnings or analyst forecasts.
