XD is a symbol used in newspapers to indicate that a stock is trading ex-dividend or without a dividend.
If a stock is bought on or after the XD date, the dividend is paid to the seller. If a stock is bought prior to the XD date, the dividend is paid to the buyer. The XD date is four business days prior to the holder-of-record date. It is the date when the right to the dividend leaves the stock.
Joan bought shares of XYZ Corporation on December 7. The holder of record date is December 10. As a result, Joan will receive the dividend because she bought the stock less than 4 days before the XD date.
