第一句话中CDOs do not provide much diversification benefit compared with corporate bonds如何理解?

NO.PZ2019103001000089

问题如下:

Wang, a junior credit strategist, made the following statements about the structured financial instruments.

Statement 1: Because the collateral for a CDO is usually corporate loans or bonds, CDOs do not provide much diversification benefit compared with corporate bonds, and they do not offer unique exposure to a sector or market factor.

Statement 2: Because of this dual protection for creditors, covered bonds usually carry lower credit risks and offer lower yields

Statement 3: The correlation of expected defaults on the collateral of a CDO affects the relative value between the senior and subordinated tranches of the CDO.

选项:

A.

Statement 1 is correct and statement 2 is wrong

B.

Statement 2 is correct and statement 3 is wrong

C.

Statement 1 is correct and statement 3 is correct.

解释:

答案:C is correct

解析:Strucured financial instruments的概念考查

解析:三个Statement都正确,为原版书原句。考试对这部分的要求是了解即可。

CDO就是由许多公司债券组成的资产池,底层资产是一堆债券,有可能是各种行业、企业发行债券的混合,分散化效果是不是比公司债好?

CDO就是由许多公司债券组成的资产池,底层资产是一堆债券,有可能是各种行业、企业发行债券的混合,分散化效果比公司债好,那么题干中CDOs do not provide much diversification benefit compared with corporate bonds说的是CDO分散化不如公司债,为什么是对的呢?

嗨,努力学习的PZer你好:


分散效果是看资产之间的相关性的,也就是ρ,因为CDO底层资产都是企业债券,而且基本都是HYB,相关性较强,风险跟单一企业债很相似,比如,容易受同一种宏观经济环境变化的影响,因此diversification效果较差,题目说的是not provide more diversification benefit compared with corporate bonds是对的,同学也可以从long CDO就exposure to default correlations这个角度考虑,他们容易同时违约,因此,根本没有diversification效果,这个结论要记住。
