Bloomberg and Rockefeller Asset Management Launch ESG Improvers Index


New York, January 11, 2021

  • New multi-factor index utilizes the Rockefeller ESG Improvers ScoreTM to provide differentiated ESG factor exposure, offering potential to outperform market-cap weighted indices.

Bloomberg and Rockefeller Asset Management today announced the launch of the Bloomberg Rockefeller U.S. All Cap Multi-Factor ESG Improvers Index, available through the Bloomberg Terminal. The index combines Bloomberg’s renowned risk model, data, and index capabilities with 40 years of ESG expertise from Rockefeller Asset Management. Unlike other ESG indices that emphasize screening around ESG leaders or laggards, this index ranks a company’s improvement in performance on material ESG issues relative to industry peers.

This multi-factor index combines the Rockefeller ESG Improvers ScoreTM, an uncorrelated and proprietary alpha enhancing factor, with quality and low volatility factors to pursue outperformance over traditional market-cap weighted indices with low tracking error and minimal sector or other factor deviations. Another distinctive aspect of the index is that it incorporates shareholder engagement techniques that help create shareholder value and catalyze positive change.

“We believe that investors will increasingly differentiate between ESG leaders and improvers – firms showing the greatest improvement in their ESG footprint,” said Casey Clark, Managing Director and Global Head of ESG Investments at Rockefeller Asset Management. “And that the latter offers a greater potential for generating uncorrelated alpha over the long-term.”

“Institutional investors are focusing now on underlying ESG factors and trends, so we are expanding our index offering to include ESG improvers,” said Alan Campbell, Head of Index Product Management at Bloomberg. “Together with Rockefeller we are providing investors with a product that captures high quality and low volatility companies that exhibit positive ESG momentum.”

“Given Bloomberg’s history as a multi-asset index provider, and our experience in the ESG space, we felt this was a natural partnership to bring ESG Improvers benchmarks to the market,” added Chip Montgomery, Managing Director and Head of Business Strategy & Corporate Development at Rockefeller Asset Management.

The index is administered by Bloomberg’s UK Financial Conduct Authority authorized benchmark administrator, Bloomberg Index Services Limited (BISL). BISL is responsible for calculation, governance and provision of the index.
