Sustainability and ESG Indices: A Booming Ecosystem and New Investing and Trading Opportunities

We see those big numbers in the press, almost daily it seems. About ESG assets under management (AUM) reaching US$40 trillion, expected to hit US$53 trillion by 2025. Or about quarterly ESG fund flows nearing US$100 billion, and the seismic shift in ESG AUM to passively-managed funds.

Recent growth in SRI (sustainable and responsible investing) and ESG (Environmental, Social, and Governance) assets and investment products would not be possible without the growing ecosystem of index providers, and the SRI/ESG indices and benchmarks that they create.

The ongoing boom in SRI/ESG indexing, which shows no signs of slowing, creates new opportunies for investors – and I do not mean investing in indexed mutual funds or ETFs. Too obvious, and too retail. I am referring to emergent opportunities associated with SRI/ESG index arbitrage.

Index rebalancing/reconstitution events often create windows of abnormal returns for constituents being re-weighted, added, or dropped. That much is obvious, and the effects of broad market index changes are well-known. For SRI/ESG indices, this is uncharted territory with huge potential.

This Smartkarma Original looks at the evolving SRI/ESG indexing landscape, and more importantly the emergent investing (e.g., stocks of listed indexers) and trading (e.g., arbitraging index changes) strategies arising from this global boom in SRI/ESG indices... from an Original perspective.

WHAT'S ORIGINAL?

Typically, discussions about SRI/ESG indices focus on their performance and in the context of that age-old "ESG-Alpha" debate – i.e., whether incorporating ESG factors into the investment process is worth the effort. To be clear, that is an important debate to have (and win). However, this report takes a different angle on SRI/ESG indices by focusing on investing and trading and strategies that capitalise on the boom in SRI/ESG indices. Theory (and a little speculation) backed by analysis.
