老师,这句话不是代表分散效果不好吗

* 问题详情,请 查看题干

NO.PZ201710200200000103

问题如下:

3. Raye believes the previous adviser’s specification for debt is incorrect given that, for purposes of asset allocation, asset classes should be:

选项:

A.

diversifying.

B.

mutually exclusive.

C.

relatively homogeneous.

解释:


C is correct.

In order to effectively specify asset classes for the purpose of asset allocation, assets within an asset class should be relatively homogeneous and have similar attributes. The previous adviser’s specification of the debt asset class includes global investment-grade corporate bonds and real estate. This definition results in a nonhomogeneous asset class.

考点:asset class的分类标准

解析:正文部分对于债券的分类分为global investment-grade corporate bonds以及real estate,显然房地产与债券的性质差别较大,所以不应该划分到同一资产类型中。违反的是homogeneous,因为homogeneous要求同一资产类型中的资产性质相似。

嗨,从没放弃的小努力你好:


老师,这句话不是代表分散效果不好吗


Raye is concerned that the asset allocation approach followed by the Laws' previous financial adviser resulted in an overlap in risk factors among asset classes for the portfolio.


Raye担心,Laws前任财务顾问所遵循的资产配置方法导致投资组合中不同资产类别的风险因子overlap。


其实这是下一道题的信息


5. To address his concern regarding the previous adviser’s asset allocation approach, Raye should assess the Laws’ portfolio using:

选项:

A.

a homogeneous and mutually exclusive asset class–based risk analysis.

B.

a multifactor risk model to control systematic risk factors in asset allocation.

C.

an asset class–based asset allocation approach to construct a diversified portfolio.


overlap风险因子是之前基金经理的不足,现在想要改进,那么应该用什么方法。


之前的基金经理是投资不同的asset class,不同的asset class可能有相同的风险因子,导致分散程度不够,如果想要解决这个问题,可以使用factor-based approach,基于不同的风险因子来投资,这样就避免了在某个风险因子上投的过于集中的问题。


而本题问的是equity和derivatives这两个asset class的分类存在什么问题。


mutually exclusive要求asset class互相不能有重叠、交叉。比如老师上课讲的例子,哺乳动物和灵长类动物,这两个分类就有重合,不是mutually exclusive的。


equity这个大类针对的asset class是US equities。


derivative这个大类针对的asset class是large capitalization foreign equities。


一个是美国的,一个是国外的,所以没有重叠。


要注意区分说的是风险因子overlap还是资产分类 overlap哦
