Dividend yield is a company's annual dividend per share divided by its current share price, shown as a percentage. It tells you the income return you would receive at today's price, separate from any change in the share price itself.
Because price sits in the denominator, the yield moves opposite to the share price. A falling share price pushes the yield up, which is why an unusually high yield can be a red flag rather than a gift — the market may be pricing in a coming dividend cut.
A healthy yield is one the company can comfortably afford to keep paying from its profits. Yield is best read alongside whether the dividend is growing, stable, or stretched, not chased on its headline number alone.
Worked example
A stock paying $2 a year in dividends and trading at $40 has a dividend yield of 5%.
