Abstract

This paper empirically shows that information acquisition affects stock returns by reducing firm-level information asymmetry. When firms disclose material information that was known by insiders, demand for information reduces the asymmetric information faced by uninformed investors and lowers the stock returns persistently. The effect is much stronger for both unexpectedly good and bad news than for anticipated news, consistent with the information asymmetry reduction channel. Moreover, demand for information has stronger effects when investors are geographically close to firm headquarters or have prior experience in collecting firm-specific information, suggesting that the cost of information processing affects information asymmetry. Furthermore, I explore an exogenous variation in information acquisition using the Northeast Blackout of 2003 as a natural experiment, and identify its causal effect on information asymmetry in a difference-in-differences setting.
