NO.PZ201812020100000205 问题如下 BaseonExhibit 2, the totexpectereturn of the funs globbonportfoliois closest to: A.0.90%. B.1.66%. C.3.76%. Bis correct. The totexpectereturn is calculatefollows:Totalexpectereturn = Rolling yiel+/–E(Change in pribaseon investor’s benchmark yielview) +/–E(Change in prie to investor’s view of cret sprea +/–E(Currengains or losses)whereRolling yiel= Coupon income + Rollwn return. 怎么看出题目中的Expecteaverage benchmark yielto-maturity change0.15%不是Prichange，而是δYiel不能直接使用，还需要用公式计算一遍δPrice。

NO.PZ201812020100000205 2.20%. 3.76%. B is corre. The totexpectereturn is calculateas: Totexpectereturn = Rolling yiel+ E(Change in pribaseon investor’s yielanyielspreview) – E(Cret losses) + E(Currengains or losses) Rolling yiel= Yielincome + Rollwn return 新考纲中没有cret loss这一项
NO.PZ201812020100000205 计算change in pribaseon yielanyielsprea直接用5.19*0.15%不行吗，为什么要考虑convexity变化？
