Abstract

Purpose – The purpose of this paper is to investigate the extent of directors breaching the reporting requirements of the Australian Stock Exchange (ASX) and the Corporations Act in Australia. Further, it seeks to assess whether directors in Australia achieve abnormal returns from trades in their own companies.

Design/methodology/approach – Using an event study approach on an Australian sample, abnormal returns for a range of situations were estimated.

Findings – A total of 13 (seven) per cent of own‐company directors trades do not meet the ASX (Corporations Act) requirement of reporting within five (14) business days. Directors do achieve abnormal returns through trading in shares of their own companies. Ignoring transaction costs, outsiders can achieve abnormal returns by imitating directors' trades. Analysis of returns to directors after they trade but before they announce the trade to the market shows that directors are making small but statistically significant returns that are not available to the market. Analysis of returns to directors subsequent to the ASX reporting requirement up to the day the trade is reported shows that directors are making small but statistically significant returns that should be available to the market.

Research limitations/implications – Future research should investigate the linkages between late reporting by directors and disadvantages to outside shareholders and the implementation of internal policies implemented to mitigate insider trading.

Practical implications – Market participants should remain vigilant regarding the potential for late/non‐reporting of directors' trades.

Originality/value – Uncovering breaches of reporting regulations are particularly important given that directors tend to purchase (sell) shares when the price is low (high), thereby achieving abnormal returns.

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
