Yield
Annual income (interest or dividends) divided by current price, expressed as a percentage.
In depth
For bonds: yield depends on coupon rate, current price, time to maturity. "Yield to maturity" (YTM) is the total return if held to maturity, including reinvested coupons. For stocks: dividend yield = annual dividend ÷ current price. Bond and stock yields move with interest rates and risk perceptions.
