The post-earnings-announcement drift is a longstanding anomaly that conflicts with market efficiency. This study documents that the post-earnings-announcement drift occurs mainly in highly illiquid stocks. A trading strategy that goes long high-earnings-surprise stocks and short...

This paper studies the effects of predictability on the earnings-returns relation for individual firms and for the aggregate. We demonstrate that prices better anticipate earnings growth at the aggregate level than at the firm level, which implies that random-walk models are inappropriate for...

This paper studies whether illiquidity affects the predictability of fundamental valuation variables. Firm-level, cross-sectional analyses show that returns of illiquid stocks contain less information about their firm's future earnings growth compared to those of more liquid stocks. A natural...
