问题如下：

Calculate the expected return that an equal-weighted investment in the three securities could provide.

选项：

解释：

答案

Estimate of the expected return of an equal-weighted investment in the three securities: (3.8% + 4.8% + 6.1%)/3 = 4.9%.

中文解析：

三种证券等加权投资的预期收益估计:(3.8% + 4.8% + 6.1%)/3 = 4.9%。

1-year government bond expected return=3.8%

10-year government bond expected return=3.8%+1%=4.8%

10-year BBB corporate bond expected return=3.8%+1%+0.75%+0.55%=6.1%

the expected return that an equal-weighted investment in the three securities could provide=(3.8+4.8+6.1)%/3=4.9%

嗨，爱思考的PZer你好：

the expected return that an equal-weighted investment in the three securities could provide=(3.8+4.8+6.1)%/3=4.9%

Hello，亲爱的同学~

这么写大致是可以的，但不是特别的推荐。

确实有一种说法是，计算题，只要最后的结果对，就给全分。但是，这种说法，只是考生之间流传的说法，并未得到协会的证实。

因此我们的建议是，把计算题的步骤写全。

同学最好把：

-year government bond expected return=3.8%

10-year government bond expected return=3.8%+1%=4.8%

10-year BBB corporate bond expected return=3.8%+1%+0.75%+0.55%=6.1%

这个计算过程也写出来哈。这样就万无一失了。
