Portfolio Tilting and SFDR market implied rating sustainability score (SMIS)
We develop a SFDR market-based sustainability score (SMIS) that incorporates the presence of certain assets in ethical funds. This approach leverages the collective judgment of asset managers by assigning high sustainability scores to companies that are overrepresented in the portfolios of SFDR Article 9 funds (dark green funds) compared to funds that are less sustainability-focused. This method allows the integration of sustainability scores, typically based on self-reported data and indicators collected by data providers, with the actual investment decisions of fund managers. Such market-based information is particularly valuable when the quality of sustainability reporting is low, as is often the case with smaller companies. We examine the financial and sustainability variables that can explain SMIS score using a quantile regression approach and evaluate the out-of-sample performance of portfolio tilting strategies based on SMIS pre-selection versus ESG ratings.
