The Market Reaction to Stock Split Announcements: Earnings Information After All

We re-examine whether the abnormal returns around stock split announcements can be explained by an information hypothesis. Our evidence establishes a link between the abnormal returns and future earnings growth. Analysts revise earnings forecasts by 2.2-2.5% around split announcements, and this revision is significantly larger than that for matched firms. We further show that the earnings information in a split likely arises from the fact that splitting firms experience less mean reversion in their earnings growth relative to matched firms. Consistent with an earnings information hypothesis, the analyst revision and the abnormal returns are stronger for firms with more opaque information environments, and the cross-sectional variation in analyst revisions is related to the variation in abnormal returns.
