There is a notion that adopting a responsible investment approach will negatively impact financial returns.
But this is a “frustratingly persistent myth”, according to Kate Elliot, head of ethical, sustainable and impact research at Rathbone Greenbank Investments.
“There is now a significant body of research to support the view that taking environmental, social and governance factors into account in investment decisions does not have to result in lower returns. Indeed, several studies suggest the opposite and that a responsible investment approach may help to enhance long-term returns.”
Jamie Govan, senior ESG investment manager at Abrdn, cites a 2019 paper by the Morgan Stanley Institute for Sustainable Investing, which details research conducted on the performance of almost 11,000 mutual funds between 2004 and 2018. The analysis showed there was no financial trade-off in the returns of sustainable funds compared to traditional funds.
Subsequent analysis of more than 3,000 US mutual funds and exchange-traded funds, published by the institute in February, showed that sustainable equity funds outperformed their traditional peer funds by a median total return of 4.3 percentage points in 2020. During the same period, sustainable taxable bond funds also beat their non-ESG counterparts by a median total return of 0.9 percentage points.
Jack Turner, an investment manager at 7IM, raises the concept of portfolio theory being based on the premise that an investor moves further away from their optimal portfolio as they limit their investment universe.
“But the real world is a lot more complicated than that,” he adds. “Would shrinking your universe by avoiding companies that rely on fossil fuels harm returns if they are more heavily regulated in the future? How profitable will tobacco stocks be if people in the emerging markets cut back on smoking? The time horizons of your investment will have a big impact here.”
Referring to the view that investing responsibly leads to underperformance in contrast to ‘agnostic’ strategies as a misconception, Oliver Jones, investment analyst at PortfolioMetrix, says the belief largely stems from the performance of ethical funds throughout the noughties that primarily relied on negative screens to exclude ‘sin sectors’, such as tobacco or arms manufacturers, which performed well over the period.
He adds: “It is our belief that going forward there will be periods when responsible investment strategies outperform agnostic approaches, and periods in which they underperform. This is largely driven by what responsible strategies do and don’t invest in.”
Jones cites the Covid-related sell-off between March and April last year, when oil and gas companies, banks, traditional auto-manufacturers and airlines performed “horribly” due to the impact of the pandemic.
“Responsible investment strategies typically have far less, if any, exposure to these sectors and so were much less impacted by the underperformance of these sectors. Agnostic strategies, and particularly those focused on the more ‘value’ areas of the market, had higher exposures to these sectors, and so felt the full force of the market drawdown.
