We 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.

We investigate whether imputation tax credits are capitalised into Australian stock prices by utilising discounted cash-flow valuation models and examining the relation between earnings yields and imputation credit yields. While imputation credits are valuable to many investors, the evidence that they are reflected in share prices is at best mixed and largely unconvincing. Our results reveal that imputation credits fail to lower realised returns casting doubts over whether imputation credits are priced from the perspective of longer-term buy-and-hold investors. If so, such investors can expect to fully benefit from their imputation credits, and imputation effects may not impact on the cost of capital. [ABSTRACT FROM AUTHOR]

This study examines the impact of company responses to trading-induced queries made by the Australian Securities Exchange over the period January 2007-December 2008, inclusive. We utilise event study methodology and a matched sample approach to assess the impact of trading query announcements. We use multivariate analysis to investigate any cross-sectional determinants affecting abnormal returns and volume, and find significant positive shareholder wealth and volume effects associated with query announcements. Further, the unexplained abnormal returns observed prior to the announcement of the trading query persist post-announcement. Subsequent analysis reveals the industry effect reported in the literature loses significance after accounting for sample selection bias. [ABSTRACT FROM AUTHOR]
