ESG Style Analysis for Equity Portfolios
Summary
The document asks whether Sharpe-style portfolio style analysis can explain equity fund performance using indices grouped by high, medium, and low ESG characteristics. It identifies suitable data as the central practical challenge and points to ESG scoring workflows as one way to assemble and apply those inputs.
The described workflow uses ESG data for a chosen universe, combines it with an investor's own research, and compares portfolio scores across holdings or scenarios. It also mentions identifying green bond issuers and examining which companies reduce a portfolio's ESG score. These are examples of data and analysis tasks, rather than a defined style-analysis model.
The discussion provides no performance results, detailed methodology for constructing ESG indices, or evidence that the proposed approach explains returns. Data access and the choice and quality of ESG measures remain important limitations; the response's examples depend on access to proprietary financial data tools.
Key ideas
- Style analysis could relate equity fund performance to indices sorted by ESG level.
- Access to appropriate ESG data is a key implementation challenge.
- An ESG scoring workflow can combine external scores with an investor's own research.
- Portfolio and scenario analysis can reveal holdings that lower an ESG score.
- The document does not specify an index construction method or report empirical results.

# ESG Style Analysis # ESG Style Analysis Hi all and thank you in advance. Do you think that implementing a style analysis on ESG equity portfolios is feasible? When I mean style analysis I refer to the seminal paper of Sharpe (1992) but I this case explain the performance of funds through indices that relate to high/medium/low ESG. Does anyone know if such indicators exist and if not has anyone been through the quantification of ESG factors? Thank you. ## Answer by David Duarte (score 1, accepted) https://quant.stackexchange.com/a/51210 I think it is feasible. You can check out this paper: A Blueprint for Integrating ESG into Equity Portfolios One of the main challenges is finding the appropriate data to perform your analysis. If you have access to a Bloomberg terminal, you can look at some of the recent webinar material (Seeing Green Spotlight Webinar) on ESG analysis that Bloomberg is using to promote it's `BQNT` (Jupyter environment inside the Bloomberg terminal) and `BQL` (new query language to extract Bloomberg information) tools. Part 1 - ESG Scoring App Workflows - Access the new ESG data available in BQL for your target universe - Use the BQuant app template to quickly build your own ESG scoring app Part 2 - Integrating Your Research into ESG Scoring Models - Use Bloomberg's custom data editor (CDE) to upload your research - Combine your research and BQuant's ESG score in a single scoring app Part 3 - Finding ESG Bonds - Create an interactive app with ESG scores for a bond universe - Identify companies that have issued green bonds Part 4 - Improving Your Portfolio's ESG Score - Visualize the largest detractors to your portfolio's ESG score - Construct scenarios to determine the ESG impact of specific companies
