Macaulay Duration
Macaulay duration is a measure of the weighted average time to receive the cash flows from a bond, expressed in years. It serves as a primary indicator of an asset sensitivity to interest rate changes.
The weights are determined by the present value of each cash flow relative to the total price of the bond. A longer Macaulay duration indicates that a larger portion of the bond value is tied to cash flows further in the future, making the price more sensitive to interest rate fluctuations.
This metric is a foundational tool in fixed-income analysis and portfolio management. It helps investors understand the timing of their returns and the inherent risk of their holdings.
While it provides a good estimate for price changes in response to small rate shifts, it does not account for the convexity of the price-yield relationship. Therefore, it is typically used in conjunction with other metrics to provide a comprehensive view of interest rate risk.
It is a standard measure that allows for the comparison of bonds with different maturities and coupon structures.
