- Environmental, Social, and Governance (ESG) considerations are an increasingly important input in investors’ portfolio decisions. We discuss how these considerations may be incorporated in a portfolio and how they may affect risk and return outcomes.
- ESG is a broad term that many investors may define differently. Thus, we begin by outlining a framework designed to clarify how ESG may enter an investment process.
- We focus here on security selection, highlighting the distinction between using ESG signals to enhance the investment view of a security’s risk or return potential and incorporating explicit non-investment objectives into a portfolio.
- Finally, we leverage a recently developed ESG-efficient frontier framework to show how ESG integration and screening lend themselves to a quantitative investment process and to quantify their expected impact on performance in several practical applications.
