Abstract

We investigate media influence on stock returns that are revised by sell-side analysts. Our main findings are twofold. First, post-announcement returns depend on whether the stock is covered by the media. Media-covered stocks demonstrate weaker post-announcement returns than their non-media-covered counterparts. Second, for media-covered event samples, we create a sentiment proxy using a unique news word count method and investigate whether pre-event sentiment affects post-event returns. Our results indicate that pre-event sentiment dictates short-run investor behavior and affects the post-announcement return in a significant manner.
