老师,这道题D为什么错了?

NO.PZ2022072902000008

问题如下:

Which of the following is an active quantitative approach to embed ESG within a portfolio?

选项:

A.Weighting ESG as an idiosyncratic factor in a multi-factor stock selection algorithm. B.Consideration of ESG scoring and relevant metrics in security-specific investment decisions. C.Minimising tracking error against benchmark indices. D.Solving the mean-variance optimisation problem to arrive at the best sectors for assetallocation.

解释:

复杂的定量方法ESG作为专有因子直接嵌入算法模型中从而推动投资组合股票选择

D是MVO的方法,也是ESG作为一个因子纳入进来了啊,那为什么不选啊?谢谢

嗨,努力学习的PZer你好:


D选项错误的原因是,题目是问在一个投资组合中结合ESG的方法。但D选项“解决均值-方差优化问题,以找到资产配置的最佳行业”虽然是一个量化投资策略的关键组成部分,但它本身并不直接涉及将ESG因素嵌入投资组合的过程。均值-方差优化是投资组合管理中的一个经典方法,用于通过最小化风险的同时最大化预期回报来选择资产配置。这一过程主要关注的是资产的预期回报和风险(方差),而不是直接考虑ESG因素。因此,D选项不是最佳选项。

----------------------------------------------
虽然现在很辛苦,但努力过的感觉真的很好,加油!
