投资经理在绿色股票与棕色股票中施展才能有多容易?

How easy is it for investment managers to deploy their talent in green and brown stocks?

David Ardia, Keven Bluteau, Thien Duy Tran

AI总结:

本文基于标普500公司2014-2020年数据,利用同行绩效比率分析绿色与棕色股票的alpha异质性,发现约20%股票能脱颖而出,但绿色股票异质性下降使投资经理更难施展才能。

摘要:

我们利用 Ardia 和 Boudt (2018) 的同行绩效比率,探讨绿色股票和棕色股票领域中已实现的 alpha 绩效异质性。以 2014-2020 年标普 500 指数公司为研究对象,并按公司的温室气体排放水平定义同行组,我们发现平均约有 20% 的股票在未来表现上与其同行区分开来。在棕色股票中,这一机会集的时间变化要大得多。此外,绩效异质性随时间推移而下降,尤其是绿色股票,这意味着投资经理在选择低温室气体强度股票时,现在更难施展其技能。

英文摘要:

We explore the realized alpha-performance heterogeneity in green and brown stocks' universes using the peer performance ratios of Ardia and Boudt (2018). Focusing on S&P 500 index firms over 2014-2020 and defining peer groups in terms of firms' greenhouse gas emission levels, we find that, on average, about 20% of the stocks differentiate themselves from their peers in terms of future performance. We see a much higher time-variation in this opportunity set within brown stocks. Furthermore, the performance heterogeneity has decreased over time, especially for green stocks, implying that it is now more difficult for investment managers to deploy their skills when choosing among low-GHG intensity stocks.
