This paper examines the mechanism through which the incorporation of information into prices leads to cross-autocorrelations in stock returns. The lead-lag relation between large and small stocks increases with lagged spreads of large stocks. Further, order flows in large stocks significantly...

A change in executive leadership is a significant event in the life of a firm. This study investigates an important consequence of a CEO turnover: a change in equity volatility. We develop three hypotheses about how changes in CEO might affect stock price volatility, and test these hypotheses...

This paper identifies a specific set of agents as noise traders in U.S. equity markets, and examines their effects on returns. These agents, who speculate using the "head-and-shoulders" chart pattern, are shown to qualify as noise traders because (1) trading volume is exceptionally high when...

Focusing on capital asset returns governed by a factor structure, the Arbitrage Pricing Theory (APT) is a one-period model, in which preclusion of arbitrage over static portfolios of these assets leads to a linear relation between the expected return and its covariance with the factors. The APT,...

Building on recent developments in behavioral asset pricing, we develop a model in which an increase in the dispersion of investor beliefs under short-selling constraints predicts a "bubble," or a rise in a stock's price above its fundamental value. Our model predicts that managers respond to...
