问题如下:

Which of the following statements about ESG indices is most accurate? ESG scores used for weightings tilts:

选项:

A.must be data-based only. B.must be ratings-based only. C.can be either data-based or ratings-based.

解释:

C is correct because "these ETFs follow the underlying index or basket construction in a rules-based fashion. These can be thematic, namely investing only in certain sectors, or tilt weightings based on ESG scores, as described earlier. These scores maybe be data-based (for example, carbon emissions) or ratings-based (for example, on a provider’s ratings), or a mix of the two. There continue to be debates as to how well these ETFs capture potential ESG factors."

A is incorrect because "these ETFs follow the underlying index or basket construction in a rules-based fashion. These can be thematic, namely investing only in certain sectors, or tilt weightings based on ESG scores, as described earlier. These scores maybe be data-based (for example, carbon emissions) or ratings-based (for example, on a provider’s ratings), or a mix of the two. There continue to be debates as to how well these ETFs capture potential ESG factors."

B is incorrect because "these ETFs follow the underlying index or basket construction in a rules-based fashion. These can be thematic, namely investing only in certain sectors, or tilt weightings based on ESG scores, as described earlier. These scores maybe be data-based (for example, carbon emissions) or ratings-based (for example, on a provider’s ratings), or a mix of the two.

嗨,努力学习的PZer你好:



"Rule-based" 是一个金融术语,用来描述投资策略或投资产品的构建方式。在上下文中,它指的是基于一定的规则或规定来构建投资组合或指数的方式,而不是依赖主观判断或人工干预。

在这个问题中,涉及到ESG(环境、社会和治理)指数和ETF(交易所交易基金),这些指数和ETF通常是按照一套事先规定好的规则或方法构建的。例如,ETF可以根据某个ESG指数来构建,这个ESG指数的构建方法是按照一定的规则来进行的,这些规则可以包括根据ESG分数来调整权重或根据特定的主题来构建投资组合。这些规则是事先制定的,而不是依赖个人主观判断。

因此,选项C是正确的,因为ESG指数和ETF的权重调整通常可以基于ESG分数,这些分数可以是基于数据的(例如碳排放数据)或基于评级的(例如某个评级提供者的评级),或者两者的混合。这些分数的使用是基于规则的,而不是基于主观的评估。

虽然现在很辛苦,但努力过的感觉真的很好,加油!
