On the Stability of the Cross-Section of Expec

Author: Avanidhar Subrahmanyam

Abstract: In this paper,we shed further light on cross-sectional perdictors of stock return performance.Specifically,we explore whether the cross-section of expected stock returns is robust within stock groups sorted by past monthly return. We find that the book market and momentum effects are remarkably robust to sorting on past returns.However share turnover is negarively related to future returns for stocks with abonrmally low stock price performance in the recent past, but postively related to returns for well-performing stocks.This casts doubt on the use of turnover as liquidity proxy,but is consistent with turnover being a proxy for momentum trading which prshes prices in the direction of past price movements.Our results are bobust to both NYSE/AMEX and Nasdaq stocks,and also robust to stratifying the sample bu time period.
