Abstract The study investigates the effects of regulation on information disclosure on the Vietnamese stock exchange. Using event study methodology, we examine the reaction of the sectors in Vietnam following the announcements of the regulation. We find evidence showing the market anticipation of the regulation in which most sectors experience negative reactions two and five days before the first announcement on the information disclosure regulation. However, our results indicate that the sectoral reactions are positive on the announcement date and the sectors continue to react in the same direction two and five days after the event day. In addition, we observe that most sectoral reaction is mainly driven by certain firms.
