问题如下:
Calculate the expected return that an equal-weighted investment in the three securities could provide.
选项:
解释:
Risk free interest rate (nominal) (%)+Premiums(%)=Expected annual fixed-income return (%)
Estimate of the expected return of an equal-weighted investment in the three securities: (1% + 2% + 3.2%)/3 = 2.1%.
解析:首先,我们先计算出每种债券各自的收益。
1-year government bond没有任何风险溢价,所以它的收益率就是1%
相比较于1-year government bond,10-year government bond存在期限溢价,因此它的收益是:1%+1%=2%
相比较于1-year government bond,10-year corporate bond存在期限溢价,信用溢价以及流动性溢价,因此它的收益是1% +1% + 0.75% + 0.55%=3.3%
又因为这三类债券投资权重相等,所以直接求算数平均就可以求得投资的回报,即
(1% + 2% + 3.2%)/3 = 2.1%.
老师,此处给的Rf=1%是名义的还是实际的?题中说incorporate 2.6%的inflation,是说合并了通胀之后的rf是1%,意思是说实际利率是负的,合并了2.6%的通胀后名义利率是1%,是这样理解吗?
另外,这种计算里是不是rf都要用名义的,如果题中给的是实际利率的话,要加通胀,是这样吗?
