Do rights matter? An intraday analysis of rights issues in Australia

Abstract

AbstractWe examine intraday abnormal returns associated with rights issue announcements in the Australian equity market over the period January 2000 to December 2022. Consistent with prior studies, we find significant abnormal returns ranging from −2.9% to −2.7% on the event day. We provide the first evidence on intraday price reactions pertaining to rights issues in Australia. Within 15 min of an announcement, we find significant abnormal trade returns of −1.2%. However, market participants are unable to profit by trading on these announcements due to transaction costs. Our results imply that the information content is fully impounded within 90 min.
