Intra‐Industry Information Transfers and the Post‐Earnings Announcement Drift

This study examines the role of intra-industry information transfers in the analyst forecast-based post-earnings announcement drift. I find that subsequent same-industry-peer earnings announcements influence a firm's post-earnings announcement drift if these subsequent announcements confirm the firm's initial earnings surprise and the firm's industry exhibits ex ante positive (common effect) intra-industry information transfers. The results suggest that underreaction to industry-specific information contributes to analyst forecast-based post-earnings announcement drift.
