C错在哪

NO.PZ2018110601000021

问题如下:

Which of the following statement regarding factor-based asset allocation is least appropriate?

选项:

A.

Factors are typically based on market premiums and anomalies

B.

A common way to construct factors is self-financing investment.

C.

Factors are typically different from the fundamental or structural factors used in multi-factor models.

解释:

C is correct

考点:factor-based asset allocation

解析:Fama-French三因素模型是典型的factor-based asset allocation,既包含market premium,又包含size和book-to-market两个基本面因子(fundamental factors/ anomalies)。构建这些因子的方法是self-financing investment,或者称作zero dollar investment,例如:Size factor return=Small-cap stock return−Large-cap stock return。

嗨,从没放弃的小努力你好:


C选项的表述是错误的,我按照正确的给你解释一遍,正确的说法应该是:

Factors are typically the same with the fundamental or structural factors used in multi-factor models

也就是说factor-based asset allocation中的风险因子与多因素模型中的factor是相同的,比如Fama-French三因素模型中的市场风险、size factor、value factor,都是factor-based asset allocation中的风险因子,比如factor-based asset allocation中的size factor就可以通过long小盘股short大盘股来实现。
