A stock I own just went ex-dividend, what is that mean?
Ex-dividend doesn’t mean extra dividend. If you’ve owned the stock during the period the dividend was declared and five days prior to the ex-dividend date, then you are entitled to payment of the dividend. The fifth day prior to the ex date is called the record date. Any name listed on the record date as an owner of the stock is entitled to that dividend. If you purchase the stock during the five days between the record date and ex date, you don’t receive the dividend. Ex-dividend merely means without dividend.
