• Socially responsible investing (SRI) is increasingly popular and prominent.
• Investing using an SRI strategy may not compromise risk-adjusted returns.
• Care must be taken to examine the credentials of SRI funds, rather than taking the label at face value.
Ethical investing is just one of the many monikers of an investment strategy that aims to look at more than just financial returns. It takes a ‘look under the bonnet’ of a company or fund to check its credentials as a contributor to positive change. ’Socially responsible investing’ (SRI) is no new kid on the block either; the increasingly popular approach has roots in centuries-old investment principles (cf. Jewish, Shari’a, Methodist and Quaker investments)1.
This heterogeneously-named investment strategy has been growing steadily since the turn of the century, as evidenced by the rising number of: UN Principles of Responsible Investing signatories2, funds incorporating ESG (environmental, social and corporate governance) principles3, value of products with ESG links4 and number of ESG indexes5. SRI is no fad, no (pure) ego-massaging exercise nor a get rich quick scheme. It’s a reflection of the changing currents of social conscience, a focus on quality (not just quantity) and ultimately a desire to ameliorate the world we live in, even if only for posterity.
At what cost?
Our pre-research preconception about SRI was that it must be more costly, in the same way that organic vegetables are more expensive than their pesticide-laced cousins. Being selective about the nature of investments would naturally have a corresponding impact on the cost of such products and/or their returns. We’re not alone in this thought process; concerns about investment performance represented nearly a fifth of the deterrent to investing in ESG funds (although we note that it caused less consternation than: a lack of viable options, a lack of qualified expertise and concerns about greenwashing)3.
We could reconcile this cost as the price of ‘responsible’ investments, although underperformance would provide a relative FI quandary. Plump for SRI, accept poorer returns yet take solace in the tan you develop basking in the sun at the top of the ethical high ground? Or attach the blinkers, select whichever strategy provides the best returns and gallop to the FI finishing line, knowing you may’ve trampled on Mother Earth a bit in the process? Fortunately, there’s an increasingly large body of research attempting to answer the pertinent question: does SRI underperform compared to an unhindered investing approach?
SRI vs. Conventional Investing – Fight!
Socially responsible companies appear to perform better financially. One paper did find ethical banking to be less profitable than conventional banking6, although another found companies with stronger ESG credentials perform better than their lower-scoring counterparts7. Companies with better sustainability credentials demonstrate comparatively better operational performance8, 9, less volatile stocks10 and exhibit less risk11. Prudent sustainability practice has a positive impact on investment performance8, and a literature review found positive correlations between a company’s sustainable activities and its financial results12.
Negative screening, i.e. excluding companies not deemed to have the appropriate level of SRI credential, is the largest ESG category worldwide4. One analysis of negative screening looked at indexes of the original ‘sin stocks’ (alcohol, gambling, tobacco, weapons, adult entertainment and nuclear power) and found that applying an ethical screen didn’t significantly impact on investment performance13. These results for the ‘Sextet of Sin’ were echoed in a later study14, however applying broader screening to exclude other ESG issues did result in portfolio underperformance compared to an unscreened portfolio.
How do SRI investments perform compared to their ‘conventional’ alternatives? There are some conflicting reports about whether an SRI approach is more likely to under- or over-perform, for both the UK and globally7, 15. One analysis found there were reduced returns when investing ethically16; another suggests that the higher fees which usually accompany SRI funds will impact on overall returns17.
A meta-analysis found that, comparing SRI to conventional investing, the occurrences of outperformance (40%) or similar performance (43%) were much higher than underperformance (17%)12. A 2020 Credit Suisse report concludes that there’s no strong of evidence of ESG fund/index under- or over-performance4. Multiple analyses support the idea that an SRI approach performs no better or worse than a conventional investment approach, and that risk-adjusted returns could be expected to be similar4, 7, 12, 15, 17-20.
Within recent memory there’s been the 2008 Global Financial Crisis (GFC) and the 2020 Covid-Crash; it’d be naive to think there’ll be anything other than plenty more downturns in the years ahead. How does SRI do in a downturn? Studies have found that Islamic indexes (i.e. investing according to Shari’a principles) outperformed conventional indexes during the GFC21 and that Islamic mutual funds even outperformed other SRI funds (2005-2015)22. SRI funds may also be more resilient during other tumultuous times23. Morningstar’s analysis of how ESG ETF’s performed in the Covid-Crash demonstrates that the majority weathered the downturn better than an equivalent non-ESG fund24.
A drive towards sustainability may improve future investment returns given that data suggests the rising global temperatures will have a deleterious effect on world GDP25, 26. Overall, the evidence we reviewed would suggest that an SRI strategy would historically not have significantly compromised risk-adjusted investment returns.
Many investors will choose to invest passively in low-cost, global equity, index-tracking funds as the mainstay of their portfolio. The ever-popular Vanguard have recently launched two new ESG funds: the ESG Developed world all-cap and the ESG Emerging markets all-cap. With fees of 0.20% and 0.25% respectively, both track the corresponding FTSE All Cap ex. Controversies/Non-Renewable Energy/Vice Products/Weapons Index. How do they stack up compared to their non-SRI equivalents?
The closest comparison to the new ESG Developed world fund is the FTSE Developed World ETF. It’s cheaper (0.12%), an ETF and does not contain small-cap companies. There are also some minor differences between the two when it comes to the geographical and sector weightings. Interestingly, Morningstar’s assessment of the sustainability of the two funds is near identical. It’s a similar story with the Emerging Market non-SRI equivalents; the Emerging Market index fund (0.23%) and FTSE Emerging Markets ETF (0.22%).
Blackrock’s iShares funds represent another cadre of popular investment choices. Their MSCI World SRI ETF and MSCI World ESG-enhanced ETF are both SRI options. Although their OCF is the same as an iShares’ non-SRI equivalent (0.20%), their sustainability ratings are far superior. Their performance appears to be slightly better too (see graph above).
We’ve chosen to highlight only a few of the plethora of available SRI investment products. The expanding breadth and availability of such vehicles mean that it’s increasingly possible to replicate the low-cost, globally diverse, passive portfolios of which many FI(RE) proponents are so fond.
Fifty Shades of Green
What about the holdings within these funds? The top 5 in any of the aforementioned SRI funds are a combination of: Apple, Microsoft, Amazon, Facebook, Alphabet, P&G, Roche, Home Depot and NVIDIA. The associated links demonstrate that none of these companies are exactly squeaky-clean when it comes to ethics, be it Roche pricing the less wealthy out of new drugs or the ever-controversial Facebook being booted from S&P’s ESG Index.
We’re not suggesting that SRI should involve only investing in companies that have never been involved in any sort of controversy, you’d be left with a shamefully small pool of choices! As fellow blogger FIREvLondon highlights, there are “dubious activities” in all spheres of industry – companies aren’t ‘green’ or ‘not green’, responsible or irresponsible, ethical or unethical; it’s a spectrum. What this does demonstrate is that just because a fund has SRI, ESG, Green or some other synonym shoehorned into its name, it doesn’t automatically make it so. It’s important to do your due diligence when it comes to choosing an appropriate SRI fund, rather than buying one that merely pays lip service to the idea.
It’s not all sunshine and lollipops when it comes to SRI; there are still various issues afflicting the strategy. Perhaps foremost, the lack of a standardised definition and inconsistent terminology is confusing for both institutional and retail investors. This opacity creates difficulty in understanding the comparability of SRI vehicles, especially given a lack of governance and poorly correlated ratings systems4. The scene is set for nefarious salespeople to slap SRI labels (and higher fees) onto products, in a bid to appeal to the values of the sustainability-conscious investor. Despite the evidence above, it’s also important to remember that the comparable performance of SRI funds in recent (<10yr) history might reflect other economic or geopolitical factors, rather than their ‘SRI-ness’ per se.
Time to Make a Change?
The winds of change are gusting. SRI is on the rise and, in time, may become the new minimum requirement for investments as the public conscience pushes inexorably in a sustainable direction. The broadening choice of socially responsible investments are increasingly compatible with a variety of portfolios/strategies and the arguments against them are dwindling. For those wishing to FI(RE) and keep the planet in good enough knick to enjoy that early retirement, SRI may be the perfect way to go.
