Abstract

ESG investing’s popularity has continually increased in the past five years. ESG data is increasingly integrated into investment processes. However, the information contained in ESG-related news for corporates has not been entirely exploited by institutional and long-only investors. The objective of this paper is to identify the benefits of ESG news information for active and factor-based investors. Indeed, one of the issues with ESG is the low frequency of scores updates. For active management, we analyze ESG-sorted portfolios in investment universes filtered by ESG news volume. Metrics of ESG-related news are sourced from Truvalue Labs, a provider of Artificial Intelligence powered ESG insights and analytics. We find that the approach of a universe focused on ESG news of corporates has been efficient in the early 2010s on the lower ESG-ranked side of the universe, but also on the higher ESG rank. More recently, it has positively contributed to more dynamic approaches of ESG investing. Finally, increasing the sensitivity to the highly visible SDGs significantly improves the return of ESG long-short portfolios.

The Market Measure of Carbon Risk and its Impact on the Minimum Variance Portfolio

Like ESG investing, climate change is an important concern for asset managers and owners, and a new challenge for portfolio construction. Until now, investors have mainly measured carbon risk using fundamental approaches, such as with carbon intensity metrics. Nevertheless, it has not been proven that asset prices are directly impacted by these fundamental-based measures. In this paper, we focus on another approach, which consists in measuring the sensitivity of stock prices with respect to a carbon risk factor. In our opinion, carbon betas are market-based measures that are complementary to carbon intensities or fundamental-based measures when managing investment portfolios, because carbon betas may be viewed as an extension or forward-looking measure of the current carbon footprint. In particular, we show how this new metric can be used to build minimum variance strategies and how they impact their portfolio construction.
