The Truthiness of ESG Criticism


Joachim Klement, CFA, is the creator most just lately of Geo-Economics: The Interaction between Geopolitics, Economics, and Investments from the CFA Institute Analysis Basis.


There are two often-repeated critiques of environmental, social, and governance (ESG) investing that I actually can’t stand. They’ve the standard of truthiness about them and are what teachers typically name “as if” arguments. For my youthful readers, the time period truthiness was coined by Stephen Colbert throughout his days internet hosting The Colbert Report on Comedy Central. Wikipedia defines it as follows:

Truthiness is the idea or assertion {that a} explicit assertion is true primarily based on the instinct or perceptions of some particular person or people, with out regard to proof, logic, mental examination, or info.

One truthiness-infused argument in investing is that the rise of index funds and exchange-traded funds (ETFs) makes markets much less environment friendly and causes inventory market bubbles. This could be true if index traders accounted for the overwhelming majority of property underneath administration (AUM). However at this time, index funds handle lower than 30% of all property. The index-funds-create-bubbles declare merely ignores this reality or assumes that the lively traders who account for the remaining 70% can’t kind an unbiased opinion and blindly observe benchmark indices, which isn’t flattering both.

In ESG investing, a equally truthy critique holds that portfolios managed with ESG overlays have to underperform their typical friends. Why? As a result of such overlays are “optimization with further constraints.” So ESG investing means excluding oil and fuel or equally ESG-challenged corporations from the portfolio. Thus, trendy portfolio principle dictates that the environment friendly frontier can’t result in the identical return as one that features these shares.

There are two issues with this rivalry. First, it assumes that ESG investing is identical as excluding sure corporations or sectors from a portfolio. That is how many individuals nonetheless method ESG investing and it’s, fairly frankly, the worst option to do it. Not solely do exclusionary screens not work, they’re counterproductive.

Fortunately, severe ESG traders moved on from exclusions a very long time in the past. The following iteration of ESG was the best-in-class method. ESG portfolios invested in all sectors however solely within the corporations with the bottom ESG threat in every sector.

Each ESG index follows this course. To make sure, best-in-class investing has its personal issues, so I’m not endorsing it. However this single modification refutes the notion that ESG investing can’t presumably have the identical risk-return trade-off as typical investing. The efficiency of the MSCI World Index and the MSCI World ESG Index demonstrates this.


MSCI AC World vs. MSCI AC World ESG Leaders

Supply: MSCI

The 2 indices are nearly an identical. Technically, the ESG index has an annualized return of 5.35% since its 2007 inception in comparison with 5.32% for the traditional index. The identical train with regional and nation indices yields the identical outcomes. The efficiency of ESG indices has roughly mirrored that of typical indices during the last decade or extra.

That, by the way in which, shouldn’t come as a shock. The most effective-in-class method mimics typical methods as intently as attainable. Which is precisely what most ESG indices have been set as much as do.

Most lively fund managers don’t outperform typical market indices and since ESG indices have nearly the identical efficiency as typical indices, this additionally means that almost all of lively fund managers don’t outperform ESG indices both.

Which brings me to the second flawed critique of ESG investing. That ESG investing has to underperform its typical counterpart as a result of it’s optimization with further restrictions is a theoretical argument: It might be true in a really perfect world nevertheless it isn’t true in any respect in apply. Fashionable portfolio principle assumes that we are able to forecast future returns, volatilities, and correlations between property with excessive precision. However in actuality, each forecast has estimation errors. The current presidential election in the US demonstrates this. Those that have been shocked by the closeness of the end result both don’t perceive estimation errors or haven’t paid consideration.



The identical is true for portfolio optimization. I’ve written about estimation uncertainty and the way it ruins our funding course of in the actual world right here, right here, right here, right here, right here, right here, right here, right here, and right here. I ought to suppose that the lesson would have sunk in by now, nevertheless it clearly has not.

In the long run, the uncertainties round our forecasts are a lot larger than any constraints that trendy ESG investing might placed on our portfolios. To contend that absolutely built-in ESG investing is constrained optimization is itself an argument constrained by truthiness. And that’s the phrase.
