This paper studies the relation between aggregate stock returns and contemporaneous and future cross-sectional earnings dispersion. We hypothesize that increases in expected earnings dispersion signal increases in uncertainty and increases in unemployment, thereby causing expected returns to...

While aggregate earnings should affect aggregate stock returns, standard portfolio theory predicts that the cross-sectional dispersion in firm-level earnings per se would not affect aggregate stock returns. Nonetheless, this paper documents that cross-sectional earnings dispersion is positively...

While aggregate earnings should affect aggregate stock returns, standard portfolio theory predicts that the cross-sectional dispersion in firm-level earnings would not affect aggregate stock returns. Nonetheless, this paper demonstrates a surprisingly robust relation between cross-sectional...
