Ex-dividend dates signal when company shares cease to trade with their current dividend payouts. There is a small intermission period before companies announce new dividends. Usually, a company's ex-dividend date falls one business day before its record date. Investors should keep this in mind when purchasing stocks because buying them on or after ex-dividend dates does not qualify them to receive the declared payment. Newly declared dividends go to shareholders who have owned that stock before the ex-dividend date. Typically, companies will announce and implement new dividend yields on a quarterly basis.

Companies use dividend yields in different strategic ways. Some companies may opt to not give yields altogether to reinvest in themselves. Other companies may opt to increase or decrease their yield amounts to control how their shares circulate throughout the stock market.
