Prior studies suggest that investors have limited attention so that stock returns are underreaction and post drift. This paper explores the relationship between the investors inattention and the stock returns after dividend announcement. Our empirical findings suggest that there is no underreaction when firms increase dividends. Furthermore, we observe less immediate response when firms decrease dividends. Our results show that stocks with dividend increase have larger price drift. This may result from other market consequences. Moreover, there is no negative abnormal return drift when firms decrease dividends. The evidence does not support that investor’s inattention influences stock returns around dividend announcement.
