Selective Insurance Group, Inc. ( NASDAQ:SIGI ) is about to trade ex-dividend in the next four days. The ex-dividend date is usually set to be one business day before the record date, which is the cut-off date on which you must be present on the company's books as a shareholder in order to receive the dividend. The ex-dividend date is of consequence because whenever a stock is bought or sold, the trade takes at least one business day to settle. Accordingly, Selective Insurance Group investors that purchase the stock on or after the 15th of August will not receive the dividend, which will be paid on the 2nd of September.
