The role of newswires in screening and disseminating value-relevant information in periodic SEC reports

We examine the role of newswires in identifying and conveying market-moving information in periodic SEC reports to capital market participants. Using data on Dow Jones Newswires, we find that newswires are more likely to send alerts on firms not releasing preliminary earnings, having credit ratings, included in major market indices, with litigation exposure, or reporting losses. Reflective of the market's focus on certain key events, firms with a nonstandard audit opinion, in the process of delisting, reporting unusual accounting items, or raising equity capital also receive alerts. Moreover, not only do we find significant price and volume reactions to the alerts at the daily level, but also we document immediate intra-day market activity triggered by the alerts, whereas no similar reaction is found for SEC filings that trigger the alerts. Additional analysis suggests that the intra-day reaction is not driven by noise trading
