This study examines the value of audit quality in the capital markets setting. We argue that higher quality auditors are associated with lower post-earnings announcement drift (PEAD). Results show that clients of brand name auditors exhibit lower PEAD than small auditors, but only weak auditor industry specialist effects are identified. PEAD also differs for clients of individual Big 6/5 auditors, with clients of the smaller Arthur Andersen and Deloittes exhibiting greater PEAD, consistent with the DeAngelo (1981) size hypothesis. Finally, PWC exhibits higher PEAD in 1998, suggesting market uncertainty about quality implications of audit market structural change.
