嗨,努力学习的PZer你好:
“这里的upward shift都是指的平行移动吧?”
不一定,我们在Reading 19学过,A sufficient, but not necessary condition For immunization is parallel shift,如下图;
也就是说,发生平行移动时,Immunization一定成功;
但是,Immunization成功时,不一定是平行移动,有可能一些非平行移动,Immunization也有可能成功。
Immunization能成功的原因就是:收益率曲线变化时,Price effect与Coupon reinvestment effect互相Cancel.
因为本题Strategy 2是已经构建好的Immunization策略,所以当曲线变化时,最有可能实现Price effect与Coupon reinvestment effect互相Cancel,Immunization成功,就对应A选项。
因为一些非平行移动,Immunization也能成功,所以本题的Upward shift可以是泛指收益率曲线移动,不一定是平行。

A is correct. An upwarshift in the yielcurve reces the bons value but increases the reinvestment rate, with these two effects offsetting one another. The price effeanthe coupon reinvestment effecancel eaother in the case of an upwarshift in the yielcurve for immunizeliability. 老师,我想问一个关于表述方面的理解\"upwarshift in yielcurve \" 是指收益率曲线平行移动吗?见过很多种表述,比如shift, parallel shift, unparallel shift, upwarshift, wnwarshift...parallel shift, unparallel shift当然可以直接判断平行移动还是非平行移动那如果是shift, upwarshift, wnwarshift这些呢?如何从表述中判断是平行移动还是非平行移动?
