Four myths about socially responsible investments debunked. Getty Images By Eleanor Laise, Senior Editor June 28, 2019From Kiplinger's Retirement Report Sticking to your principles feels good. But could it also be good for your portfolio?SEE ALSO: 8 Great Vanguard ETFs for a Low-Cost Core That’s the question raised by “sustainable” funds, an umbrella term for a diverse group of mutual funds and exchange-traded funds that generally incorporate environmental, social and corporate governance (ESG) criteria in their investment processes. Typically, that doesn’t mean simply avoiding “sin” stocks such as alcohol, tobacco and firearms companies. The majority of these funds take a more active approach. They may seek out companies that have a strong track record on pollution, product safety and human rights; buy bonds that fund renewable energy projects; or actively engage with portfolio companies on board diversity or other governance issues. Fund companies and investors are seeing the virtues—and potential profits—of values-based investing. There were 351 sustainable U.S. mutual funds and ETFs at the end of last year, according to investment-research firm Morningstar, up nearly 50% from 2017. And for the third consecutive year, sustainable funds took in record net new money in 2018, Morningstar found, even as the overall U.S. fund industry suffered its worst year since 2008. Sponsored Content While sustainable investing is often portrayed as a millennial phenomenon, baby boomers are also flocking to these funds as they increasingly look for opportunities to align their portfolios with their values. A 2018 survey by American Century Investments found that 44% of boomers are drawn to investments designed to have a positive social impact. But sustainable funds are not always easy to navigate. As demand for ESG investments has grown, for example, so too has the number of research firms that rate companies on ESG criteria. Different funds may rely on different ratings when selecting portfolio holdings. Although sustainable funds were long focused on certain market segments, such as U.S. large-cap stocks, they now cover every major asset class, making it possible for investors to build a complete, diversified portfolio of these funds. Their investment strategies have also evolved, in many cases shifting from a focus on excluding certain industries to including sustainability leaders in each industry. Instead of simply avoiding energy companies, for example, they might focus on those that invest heavily in green technology, says Shana Sissel, senior portfolio manager at CLS Investments. “That actually encourages companies to move away from bad habits,” she says, and “to take more and more positive, impactful steps for the broader good.” Advertisement Investors clinging to outdated perceptions of sustainable funds may be missing opportunities in this fast-growing segment of the fund world. Here’s a look at sustainable-fund fact and fiction. Myth 1: These are niche products for Greenpeace-activist types. Many sustainable funds are broadly diversified portfolios meant to serve as core holdings—and in fact, you may already hold one and not even realize it. In the past couple of years, a growing number of fund firms have been adding ESG criteria into the investment processes of existing, plain-vanilla funds. When this happens, “the disclosures tend to be fairly limited,” says Henry Shilling, founder and director of research at Sustainable Research and Analysis, in New York City. For example, a fund may simply amend its prospectus to note that it’s integrating ESG factors into its investment decision-making, he says, “and some investors may not be aware of the fact.” Myth 2: Sustainable investing means sacrificing returns. “That’s a holdover perception” from a time when these funds’ primary strategy was excluding “sin” stocks or whole industries from their portfolios, Shilling says. Anything that narrows the potential investment universe, the theory went, could be a drag on returns. But each year from 2015 to 2018, a majority of sustainable funds have landed in the top half of their respective categories, according to Morningstar. In 2018, the stock market’s first down year since the financial crisis, that figure was 63%. “This is not a donation—this is an investment,” says Brie Williams, head of practice management at State Street Global Advisors. “Performance is paramount.” Advertisement Most of these funds have short track records, however, and there’s no guarantee they’ll outperform over the long haul. But there is reason to believe that ESG issues can affect a company’s bottom line. Good environmental practices, for example, could help companies avoid costly accidents, while treating employees properly could help attract and retain high-quality workers. What’s more, companies that effectively manage ESG issues tend to be higher quality, lower-volatility holdings that may hold up relatively well when markets go haywire, according to Morningstar. Myth 3: Sustainable funds are expensive. Sure, some sustainable funds are more expensive than their average category peers. That’s in keeping with many investors’ thinking that a sustainable strategy adds an extra level of screening and research that will raise fund fees. But the price war that has driven some index-fund fees down to zero is also taking shape among sustainable ETFs. Vanguard and DWS Investments, for example, have recently launched sustainable ETFs charging just 0.12% and 0.10%, respectively. ESG ETFs are likely to get even cheaper from here, says Elisabeth Kashner, director of ETF research and analytics at FactSet. Myth 4: If you’ve seen one principles-based fund, you’ve seen them all. These funds aren’t easily pigeonholed, in part because “we have a great diversity of values,” Kashner says. The principles-based funds she tracks, for example, include the Point Bridge GOP Stock Tracker ETF (symbol MAGA), which holds companies whose employees and political action committees support Republican candidates, as well as Impact Shares YWCA Women’s Empowerment ETF (WOMN), which holds companies that support gender equality. Advertisement There are also plenty of diverse opinions when it comes to rating companies on ESG factors. Shilling estimates that as many as 125 firms globally now offer such ratings, and a company that scores highly in one rating system may fare poorly in another.

Read fund annual and semiannual reports and manager commentary, Shilling suggests, to find out if the strategies in the prospectus are reflected in the actual investment decision-making.
