Dunelm Group plc ( LON:DNLM ) is about to trade ex-dividend in the next three days. The ex-dividend date is one business day before the record date, which is the cut-off date for shareholders to be present on the company's books to be eligible for a dividend payment. The ex-dividend date is important because any transaction on a stock needs to have been settled before the record date in order to be eligible for a dividend. Meaning, you will need to purchase Dunelm Group's shares before the 10th of November to receive the dividend, which will be paid on the 5th of December.
