Q2. Carol Stephens, CFA, manages a relatively small portfolio for one of her clients. Stephens feels that interest rates will change over the next year but is uncertain about the extent and direction. She is confident, however, that the yield curve will change in a nonparallel manner and that modified duration will not accurately measure her portfolio's yield-curve risk exposure. To help her evaluate the risk of her clients' portfolio, she has assembled the table of rate durations shown below.
