**CFA Practice Question**

Cindy Bolan has an 11.00%, 9.00 bond that is selling for a price of $140.3830 and is currently yielding 5.30%. The table below shows how the price will vary given a one basis point change in market interest rates with a modified duration of 6.28. In this instance, what is the Price Value of a Basis Point (PVBP)?

A. $0.0882

B. $0.0705

C. $0.1146

**Explanation:**The formula for the Price Value of a Basis Point (PVBP) is equal to:

modified duration * (.0001) * 100 * price = 0.0628% * the initial price of 140.3830

Another approach is to use PV

_{-}and PV

_{+}: PVBP = (140.4712 - 140.2949)/2 = 0.0882

I took the New Price with one Basis Point Increase - the New Price with one Basis Point Decrease and divided this by 2 and got the same answer. Was this also a way to find the answer, or just luck? |
