Abstract

We investigate the impact of legal insider trading announcements on stock returns in Vietnam. Vietnamese insiders must announce their trading intentions in advance as well as after the actual trade, which contrasts with the vast majority of countries where only post-trade announcement is mandatory. This regulatory setting allows to put to test the predictions from the theoretical models of advance disclosures (Huddart et al., 2004, Lenkey, 2014). Consistent with the theoretical literature, we find that the abnormal returns are large and significant after the pre-trade announcement, showing that the market takes into consideration the information content of the insiders' intention to trade. In addition, no significant stock price effect is found after the announcement of the actual trade occurrence or cancellation. We argue in favor of the implementation of advance disclosure policies since they help mitigate the returns obtained by insiders, better share the profits with outsiders and contribute to a better information dissemination.
