Dollar Duration - CFAI shows 2 formulae
Vol 4
Reading 28 (Page 30)
Dollar duration = Duration * Portfolio Value * 0.01
Reading 30 (Pg 119) When discussing the hedge ratio…
“The product of the duration and the price is the dollar duration”
My inclination is to go with the first formula, because DD is supposed to be for a specific yield change. Or is it the fact that given the nature of the hedge ratio, the 0.01 cancels out on both the numerator and denominator? Any clarification would be much appreciated.
Thanks! |
