Basic formula
A simple trailing dividend yield divides recent dividend payments by the latest share price. Data providers may use different periods or assumptions.
Trailing vs forward yield
Trailing yield looks backward. Forward yield uses expected future payouts. DividendTen labels the method used on each data page.
Common limitation
A high yield can reflect a falling share price, a special dividend, or an unstable payout. DividendTen therefore avoids recommendation language.
