This paper empirically shows that information acquisition affects stock returns by reducing firm-level information asymmetry. When firms disclose material information known by insiders, information acquisition reduces asymmetric information and lowers stock returns. The effect is stronger for both unexpectedly good and bad news than anticipated news and when investors have a lower cost of information processing. Using the Northeast Blackout of 2003 as a natural experiment, I explore an exogenous shock in information acquisition and show causally that information acquisition reduces information asymmetry in a difference-in-differences setting.
