Socially responsible investing an expensive taste: James Saft

[August 03, 2017] By James Saft

(Reuters) - Other benefits like peace and a livable planet notwithstanding, the financial cost of socially responsible investing appears to be high.

Socially responsible investing (SRI) has been one of the few boom areas of active management. Funds managed to SRI mandates soared to $8.1 trillion in 2016 from just $1.4 trillion in 2012, according to the Forum for Sustainable and Responsible Investment.

Rather than simply gunning for the highest return, SRI seeks good returns but screens companies for other factors like environmental and social impact. Though the range of SRI screening criteria varies, they generally include a company’s impact on the environment, the communities in which it operates and its corporate governance.

The academic findings on the success of SRI judged by traditional investing criteria have been mixed. A 2009 study found that 'sin stocks' like alcohol, weapons and tobacco deliver about 2.5 percent of extra or 'abnormal' return a year compared to the general market. Other studies, however, have shown mixed results on the effect in practice of SRI, with some showing worse overall results and some better.

A new study from the University of Rome and the University of Groningen looks at the impact of a preference or 'taste' for SRI holdings and finds it to be both large and negative.

“With respect to the taste effect, investors seem to pay a price in terms of lower returns due to their preference for SRI. The premium related to the responsibility score, the price of taste, is negative, significant and stable across all model specifications,” Rocco Ciciretti, Ambrogio Dalò and Lammertjan Dam write in a paper released in June.

Studying 1,000 global firms between 2005 and 2014, the study found evidence that a preference for SRI led to an underperformance of a huge 4.8 percentage points annually.

The authors argue that the trend towards SRI can be explained in one of two ways: SRI assets have better risk characteristics; or, investors have a taste for them for other reasons.

The risk aspect was well illustrated last week when tobacco stocks fell sharply on news that the FDA may seek to limit addictive nicotine in cigarettes. (It must be said that tobacco companies, risks aside or perhaps because of the risks, have massively outperformed the broad market for decade after decade.)

The new study attempts to control for the risk characteristics which might attract or repel SRI investors in order to get a cleaner view of the impact that a preference for these stocks has on returns. This is done, in part, by identifying which firms score best on a range of factors from corporate governance to community involvement to environmental stewardship.

MIXED RESULTS, MIXED MOTIVATIONS

Adjusting those firms for risk, the study then looked at portfolios comprised of companies scored on SRI criteria on an ascending basis and found that as pro-social behavior in companies rises, stock market outcomes decline. The same results, more or less, were found on an individual company basis, as opposed to portfolios of companies.

None of this is a 'pure' view of the impact of SRI, however, in part because the criteria used to screen companies on their SRI performance have different objectives. Corporate governance, for instance, is generally about protecting the rights and interests of shareholders from the depredations of insiders. Environmental criteria, on the other hand, put a value on climate and other considerations, effectively putting the interests of other stakeholders above those of shareholders. It may well also be that the period studied, which included both the great financial crisis and its monetary-policy-fueled aftermath, is not a fair sample.

To be sure, the findings don't argue, per se, against the practice of socially responsible investing, which investors may believe produces excellent results on an 'all-in' basis taking into account its impact on more than simply financial grounds. It is also true that the decision to opt for SRI investments is a lot more simple for an individual making the call on her own behalf than it would be for pension fund trustee acting for others.

There are also complex arguments to be made about the efficiency of the use of capital markets, as opposed to outright regulation, as a means of encouraging the desired behavior by corporations.

Instead, the upshot may be that SRI is like a cake; you can have it or you can eat it, but not both.
