选项c感觉好像也是同样的意思呢?

NO.PZ2022071601000011

问题如下:

Why is ESG investing a concern for investors who are cautious of high tracking error?

选项:

A.The perception that exclusion resulting from ESG will distort the weight of sectors and countries in the portfolio in comparison to the benchmark

B.The understanding that exclusion results in fewer available securities to invest in and thus, a more limited investment universe

C.The belief that high-performing stocks may be excluded due to negative ESG characteristics, resulting in underperformance in comparison to the benchmark

D.The awareness that ESG investing requires a redefinition of active risk

解释:

对于非常关心tracking error很高的投资者来说,对ESG investing的担忧主要来源于,当去除了那些ESG因素不好的公司之后,那么去除之后的行业的比重相较于大盘来讲,就会有所偏移,就是A选项。

c选项我的理解是 一些财务表现好的个股由于esg表现不佳所以被排除在投资组合外,导致与benchmark有所偏差

嗨,爱思考的PZer你好:


这里提到组合和基准不一样,主要是为了简洁介绍什么是tracking error。

跟踪误差(tracking error)是指投资组合的回报与基准指数回报之间的差异程度。它用于衡量投资组合相对于基准的偏离情况。例如投资组合和基准中的投资标的都是一样的,但是投资权重不同,导致二者的收益率不同,经过对其收益差的标准差计算就会得到跟踪误差。

跟踪误差的公式如下,简单了解,不会考察:

嗨,努力学习的PZer你好:


C选项前半句的确表达了一些因为ESG而被排除的股票,但是tracking error主要表达的是组合和基准不一样,而不是组合比基准表现差。A选项是原文结论,表达准确。
