Event studies, introduced by Fama et al. (1969), produce useful evidence on how stock prices respond to information. We conducted an event study analysis for the Romanian companies listed on Bucharest Stock Exchange with respect to dividend announcements by using a simple market model. After defining positive, negative and normal events we concluded that the cumulative abnormal returns computed for a 41 day window do not provide relevant evidence that the market is efficient.
