Yield
Definition
The income an investment produces relative to its price or value, usually expressed as an annual percentage. Different yield measures use different calculations; yield is not the same as total return.

Why does a bond’s yield rise when its price falls?
A bond’s stated coupon stays fixed. If a bond pays $40 a year, its current yield is 4% at a $1,000 price and about 4.44% at $900. Yield to maturity also accounts for the price paid relative to the amount repaid at maturity.
