The prediction of post-earnings announcement drift using a measure of market underreaction
Prof. Steve C. Lim
Associate Professor, M.J. Neeley School of Business
Texas Christian University, USA

In this paper we develop a theory-based empirical measure of underreaction to earnings announcements that results from an asymmetric usage of earnings information. In our model, the squared correlation coefficient between order imbalance and earnings surprise ( 2r ) is the empirical measure of underreaction that one can use to predict the size of the post-earnings announcement drift (PEAD). Specifically, we show that 2 r × = k PEAD , where is the information content of earnings. The predictive power of 2r is higher than that of firm attributes prior studies have identified to explainPEAD, including the bid-ask spread, opinion divergence, firm size, analyst following, and institutional ownership. A trading strategy based on 2r generates the Pastor-Stambaugh four-factor alpha of 8.25%.
