问题如下：
If a fixed-income investment manager is concerned about the dispersion of the change in the nominal yield for a change in the real yield, which hedging method is effective when he carries out fixed-income hedging?
选项：
A.Regression hedge.
B.DV01 hedge.
C.convexity hedge.
D.Principal hedge.
解释：
A is correct.
考点：Empirical Approaches To Risk Metrics And Hedging
解析：DV01 hedge 假设了债券和假定的对冲工具的收益率上升和下降相同的基点数； 因此，对于DV01 hedge，交易者无法顾及名义利率与实际利率之间的变化差异。
is concerned about是说 worry about吗？那他很worry about real yield 和 nominal rate不一致，，不就应该，，别用这个方法选D吗。。。
我竟然俩月前问过这道题。。但有问题的地方不一样，，，是我现在sa了吗九敏九敏！！
