Macaulay Duration and Modified Duration
Macaulay Duration:
Represents the average time it takes for an investment to mature or be settled.
It is calculated by summing the durations of all coupon payments and principal repayments over the life of an investment.
Macaulay duration is useful for analyzing interest rate risk exposure in fixed-income securities.
Modified Duration:
Takes into account the time value of money by adjusting the durations of cash flows to their present values.
Modified duration reflects the effective duration of an investment after accounting for its time value.
It is used in conjunction with Macaulay duration to determine the effective interest rate for an investment.
Differences between Macaulay Duration and Modified Duration:
Calculation: Macaulay duration uses simple arithmetic calculations, while modified duration incorporates the time value of money.
Purpose: Macaulay duration provides a basic measure of the average maturity of an investment, while modified duration helps adjust for its time value impact.
Relevance: Both concepts are essential for understanding and managing interest rate risk in fixed-income securities
