The aim of this study is to measure the impact of the disclosure of the dividend policy on the share prices for the listed companies in Dubai Financial Market as an event, which sends signals on the status of the company and its future prospects, hence leading to change their stock prices. In order to achieve this objective, we used the event study methodology as we are dealing with an applied study, which is looking for the relationship between stock prices and financial events. We take five days before and after the event for a limited sample of 22 companies announce dividends during 2011.
