Millennials have led the way in investing in companies that make an effort to protect the environment and society. Known as “impact investing,” this approach has spread beyond the millennial generation to baby boomers and older investors.

Impact investing is not a new concept, but the trend has become so popular that many mutual funds are specializing in principle-based investing. This is often measured by attention to ESG – or environment, social and governance – criteria. The idea is to find investments that help people and the planet, and that have a reasonable wage spread between executives and employees.

We've selected five mutual funds that specialize in impact investing based on their commitment to ESG screening and their ability to produce positive year-to-date returns. All figures are current as of Oct. 1, 2018.

1. Parnassus Endeavor Investor (PARWX)

The focus of this fund is on companies that have good work environments for employees. The purpose of this focus is to both support employee well-being and find companies that are superior competitors because of better employee retention.

Parnassus Endeavor Investor tends to look for companies it believes are undervalued and seeks to realize capital appreciation by investing in these companies. PARWX avoids firms that are involved in alcohol, gambling, tobacco or other “vice” industries, as well as fossil fuel companies.

Parnassus uses advanced techniques for ESG screening to establish its universe of companies to choose from, then narrows its selection to 30 or 40 companies with strong fundamentals. The fund has an average yield of 14.0% over a five-year period.

  • YTD Return:   5.11%
  • Expense Ratio (net): 0.92%
  • Morningstar Rating  ★★★★★
  • Morningstar Risk Rating     Above Average
  • Net Assets:     $5.19 billion
  • Yield:   1.90%

2. TIAA-CREF Social Choice Bond Retail (TSBRX)

This fund seeks income and capital appreciation at the same time. Approximately 80% of the fund’s assets are in bonds of companies that meet ESG standards. Note that the fund invests in municipal bonds and U.S. government bonds in addition to corporate bonds. It may also buy mortgage-backed securities.

TSBRX has a target of 10% of its assets in socially and environmentally positive companies. It may invest in affordable housing, community development, sustainable energy or natural resources.

The other 90% of the portfolio may not pass the ESG test, so this fund is for those who can accept some focus on impact investing while seeking returns from more traditional companies.

  • Expense Ratio (net): 0.65%
  • Morningstar Rating  ★★★★
  • Morningstar Risk Rating     Average

Walden is willing to invest in any size company but tends to have large corporations in its portfolio. Money managers screen companies according to ESG guidelines.

That said, the company does own McDonald’s and Conoco Phillips, as well as Nike, three companies that present problems for some impact investors. The fund will not invest in weapons, nuclear plants, or alcohol or tobacco companies.

The Bottom Line

Mutual funds are moving quickly to create products for impact investors. But as you can see from the descriptions of the funds on this list, you must carefully weigh what each one considers to be socially responsible investing. Some of the funds put a small percentage of assets into impact investing, while others dedicate a complete portfolio of responsible companies.
