What is Duration?

Duration is a measure of a bond or a bond fund's price sensitivity to changes in interest rates. Duration is defined as the weighted average term to maturity of a security's cash flows, where the weights are the present value of each cash flow as a percentage to the security's price. The greater a bond or fund's duration, the greater its price volatility in response to changes in interest rates.
