Ex-Dividend Date
When a company declares a dividend, it sets several key dates. The ex-dividend date (often shortened to "ex-date") is the most market-relevant. To qualify for the upcoming payment, a buyer must purchase shares before this date — owning them on the ex-date itself is too late. Settlement conventions mean that a standard stock trade typically takes two business days to fully process, so the ex-date effectively functions as a two-day-before-payment-record deadline in practice. Check upcoming ex-dates in the economic calendar.
On the ex-dividend date, the share price usually drops by approximately the dividend amount at the market open. This is a mechanical adjustment, not a sign of trouble. Suppose a stock closes at $50 the day before its ex-date and the dividend is $1.00 per share. Historically, markets have opened that stock near $49 the following morning — the price reflects that new buyers are no longer entitled to that $1.00 payment.
Readers sometimes confuse the ex-dividend date with the payment date, which is when the cash actually arrives in shareholder accounts — often weeks later. There is also a record date, which the company uses to confirm its list of eligible shareholders. The ex-date is set one business day before the record date, but for most traders the ex-date is the operationally significant one. See dividend yield for how payouts relate to price.
