问一道题:NO.PZ2019103001000073

问题如下:

Petit develops investment recommendations for a currency-hedged portfolio of US and European corporate bonds. She expects US interest rates to decline relative to European interest rates. Furthermore, the spread curve for US corporate bonds indicates that the average spread of five-year BB bonds exceeds the average spread of two-year BB bonds by +90 bps. Petit expects the difference between average credit spreads for these two sectors to narrow to +50 bps.

Based on Petit’s expectations for US and European corporate bonds, which of the following positions relative to the portfolio’s benchmark should she recommend?

选项:

US Bonds
European Bonds
US Two-Year BB
US Five-Year BB
A.
Overweight
Underweight
Overweight
Underweight
B.
Overweight
Underweight
Underweight
Overweight
C.
Underweight
Overweight
Underweight
Overweight

解释:

B is correct.

Petit should recommend markets in which yields are expected to decline relative to other markets. As a result, Petit should recommend overweighting US bonds relative to European bonds and overweighting US five-year BB bonds relative to US two-year BB bonds.

为什么5年的spread高于2年的还要overweight?

嗨,从没放弃的小努力你好:


“为什么5年的spread高于2年的还要overweight?”


这道题的题干,表达的不是5年的Spread高于2年的Spread这个意思。



这块对应的题干信息如下:

the spread curve for US corporate bonds indicates that the average spread of five-year BB bonds exceeds the average spread of two-year BB bonds by +90 bps

首先它是分析Spread curve;Spread curve反映的是Spread与期限之间的关系。如下图:

一般的Spread curve长的如下图所示,也就是向上倾斜,原因是长期债券“夜长梦多”,有更大的Spread。


the spread curve for US corporate bonds indicates that the average spread of five-year BB bonds exceeds the average spread of two-year BB bonds by +90 bps

然后他说,5年期债券的Spread,超过2年期债券Spread为90bps,也就是:

5-year spread 减去 2-year spread = 90 bps;

题干有告诉预测:Petit expects the difference between average credit spreads for these two sectors to narrow to +50 bps.

Petit这个人预测,这个差距会降低到50bps(the difference between average credit spreads),也就是:

5-year spread 减去 2-year spread = 50 bps;

所以是5-year spread相对下降、2-year spread相对上升,这样才会造成Difference从90bps下降到50bps。

所以我们Overweight spread相对下降的债券以获取Capital gain,Underweight spread相对上升的债券,以避免过多的Capital loss。

谢谢,很棒的解答,应该加在原题的答案中的

spread curve 与 yield curve 有什么关系?



Yield curve反映的是债券的收益率;Spread curve反映的是债券的Spread,区别就在这里。

债券的Yield = Benchmark yield + spread;

所以Yield curve,反映的是债券收益率的期限关系;

而Spread curve是把基准利率剥离掉,只反映Spread的期限关系。

同理,如果我们知道基准利率的Yield curve,也知道某公司、某级别债券的Spread curve,那两者叠加起来,就可以知道该公司债该级别债券的Yield curve。
