Investor Attention and Stock Returns

Author: Jian Chen, Guohao Tang, Jiaquan Yao, Guofu Zhou

We find that investor attention proxies proposed in the literature collectively have a common component that has significant power in predicting stock market risk premium, both in-sample and out-of-sample. This common component is well extracted by using partial least squares, scaled principal component analysis, and principal component analysis approaches. Moreover, this component can deliver sizable economic gains for mean-variance investors in asset allocation. The predictive power of investor attention for the aggregate stock market primarily stems from the reversal of temporary price pressure and from the stronger forecasting ability for high-variance stocks.
