Impact Investing In Public Markets
One of the defining features of listed equities and publicly owned companies is that their shares trade on an exchange. When investors buy or sell shares through such secondary transactions – does their capital provide much additionality and encourage sustainable business practices? With the massive growth of passive investment strategies in public markets, most commonly in ETFs, is it possible to implement effective impact investing approaches is listed companies?
The answer is complex, however the explosion of ESG, sustainable and impact funds in public markets suggest investors are seeking a change in how their money is invested in this asset class
The growth of this segment of the market has been due to two main reasons, firstly increasing acceptance that social and environmental value creation is not in conflict with financial returns, and it even underpins and drive investment returns in a virtuous circle. Secondly, investors and their advisers are looking for ways to scale impact investing tools and techniques for use in the large public markets and thus allow for impact to be achieved across all asset classed in investment portfolios.
Most importantly to note, historic data shows that investing in a socially responsible way does not necessarily compromise performance:

SRI, ESG and Impact Investing
Constrained investing practices have been in existence for a long time, traditionally driven by religious or moral values. As the market has developed several acronyms have emerged to classify fund strategies. They are listed below ordered from least to greatest impact intention:
ESG investing – the inclusion of environmental, social and governance considerations to complement standard investment analysis. Examples are potential litigation, regulatory or reputational risks, which tend not appear in a fundamental analysis. It is important to note that the inclusion of ESG factors is simply an attempt to improve valuation accuracy, and thus does not preclude investments in certain industry sectors such as tobacco.
Socially responsible investing (SRI) – an active or index strategy which filters investments according to screening criteria set by the asset manager. The screening process can remove, underweight or overweight investments in a portfolio. An traditional example is a public equity fund whose portfolio tracks an index but drops companies with business activity in tobacco, gambling and arms.
Impact investing – builds on the prior two strategies by specifically focusing on companies intentionally creating and measuring impact. For this reason most impact investing public equity funds have a greatly reduced number of holdings (around 50) and typically a longer holding period. This reduced portfolio size helps make it possible for fund managers often seek management engagement to improve impact measurement and reporting practices.
Is it Possible to Create Impact by Investing in Listed Companies?
An occasionally mentioned impact investing criteria is additionality, the ability to demonstrate a measured impact would not have occurred without the investment being made. This criteria has led some to question the validity of impact investing in public markets, since the trading of public equity usually takes place in secondary markets and thus investment capital is not directed to the selected companies. However, investing in public markets provides liquidity, upwards pressure on stock prices, and can provide an opportunity for engagement and lobbying of management.

Listed, or public equity is an important asset class to mobilising capital for impact as it meets the needs of many institutional investors. The investment scale and risk profile of large pension funds for example is not suitable for investments in early-stage private equity. Thus providing these investors with impact investing opportunities is an important part of the puzzle to making use of global capital markets effectively, especially as institutional investors face increasing pressure to include impact in their mandates.
Aegon Asset Management also note that many asset managers are in fact active in fixed income (some more so than equities). Additionally some are active in impact investment without this necessarily leading to impact-themed funds or products.
Difficulties arise with terminology and classification in this segment – what does it take to label a listed equity investment as an impact investment? Different funds with different strategies each incorporate SRI, ESG and impact investing principles to different degrees and as of the time of writing the GIIN only lists 8 as meeting their criteria on their ImpactBase database.
Job Roles
Impact investing job roles in asset management follow the normal industry hierarchy seen at funds. Listed equity/debt fund managers will have teams of analysts, sometimes shared with other funds. Therefore positions on impact funds will be typically be senior roles – the fund manager or on the fund’s direct team. Public company analysis experience is key, as is experience and knowledge of impact management. Timing is key to align with the creation of a new fund, but it is also worth networking with ratings agencies and related organisations if impact in the public markets is your area of interest.
