Ch.-14, Effective Duration (pg 20)
The effective duration is a measure of the rate of change in value of A with i. It means it measures the change in present value of payments with respect to change in interest rate. But at the bottom of pg23 it is written that 'Both the volatility/effective duration and DMT provide a measure of AVERAGE LIFE of an investment'. Yes, I agree DMT measures the average life but how Volatility provide a measure of average life?
Please anyone clarify
Thanks
