Abstract:     
I introduce a method for gauging qualitative similarity in the information environments between firms based on linguistic commonality in their newswire text. I find that this new measure of qualitative similarity predicts future cross-firm return correlation even after accounting for the pair’s contemporaneous price comovement. I also provide support for an existing theory of information-driven comovement by demonstrating that the relation between contemporaneous qualitative similarity and future return correlation changes in response to market conditions and firm characteristics. I find that aggregate comovement increases when investors focus their information consumption on firms whose payoffs covary strongly with many other companies.
