What Dividends Represent and What Drives Yield
A dividend is a direct distribution of cash from the company to its shareholders, typically paid quarterly from retained earnings or free cash flow. Dividend yield expresses the annual dividend as a percentage of the current share price. A $2 annual dividend on a $40 stock yields 5%. Critically, yield is not set by management -- it is the result of the dividend amount and the market price. When a stock falls 40% but the dividend is maintained, the yield doubles automatically. This mechanical relationship is the source of the yield trap: high yields often emerge from price declines that the market correctly anticipates will be followed by a dividend cut, not from genuine income opportunity.
Payout ratio -- dividends as a percentage of earnings -- is the first sustainability screen. A 30% payout ratio on durable earnings is extremely safe; the company retains 70 cents of every dollar earned to reinvest or for balance-sheet flexibility. A 90% payout ratio leaves almost no buffer for earnings variability. But payout ratio has its own distortion: companies with volatile earnings (cyclicals, resource companies) can look high-payout in a down year and low-payout in a boom year. The more reliable sustainability metric is the FCF payout ratio -- dividends as a percentage of free cash flow rather than accounting earnings, which strips out non-cash items and capital expenditure timing effects.
Dividend Yield = Annual Dividend Per Share / Current Share Price
Earnings Payout Ratio = Annual Dividend / Diluted EPS
FCF Payout Ratio = Annual Dividend / Free Cash Flow Per Share
