X Factor: 5 Stocks Reaching Their Ex-Dividend Date on February 28

Nine stocks will reach their ex-dividend date next Thursday, which is significant for investors as the seller of the stock on that date, not the buyer, receives the most recent dividend.

A stock must be bought one day before the ex-dividend date to claim any dividends that have been announced but not yet paid. The company determines on the record date, which usually occurs two days after the ex-dividend date, which shareholders qualify for the dividend. Shareholders listed as holders of record after the record date then receive their dividend on the date of payment established by the company. Those purchasing right before the record date forfeit the dividend and normally get the stock for a reduced amount.

It may seem an anachronism in this era of high frequency trading, but the dividend rate rules are in force since it can still take up to three business days for transactions to be credited to and settled in an investor's account.
