Millennials have been leading the way in insisting on investments 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: environment, social and governance. The idea is to find investments that help people and the planet, and that have a reasonable wage spread between executives and employees. (See also: Impact Investing Funds: What are the Risks?)

We have selected five mutual funds that specialize in impact investing. The funds were chosen based on their commitment to ESG screening, and their ability to produce positive year-to-date returns. All figures are current as of April 11, 2017.

1. Parnassus Endeavor Investor (PARWX)

The focus here is on finding companies that have good work environments for employees. The purpose of this focus is twofold: 1) to support employee well-being, and 2) to 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. It also eliminates 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:   4.12%
  • Expense Ratio (net): 0.95%
  • Morningstar Rating  ★★★★★
  • Morningstar Risk Rating     ★★★★
  • Net Assets:     $3.87 billion
  • Yield:   0.92%

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.

  • YTD Return:   1.24%
  • Expense Ratio (net): 0.68%
  • Morningstar Rating  ★★★★★
  • Morningstar Risk Rating     ★★★★
  • Net Assets:     $1.12 billion
  • Yield:   2.18%

3. Vanguard FTSE Social Index Inv (VFTSX)

This fund eliminates alcohol and tobacco companies, as well as nuclear power companies and firms that sell to the military. Stock screeners demand workplace diversity, with a minimum of one woman on the board of directors and no human rights violations.

Out of some 400 stocks, the top three holdings are Apple, Alphabet, and Microsoft. There is strong representation of health care and technology. The fund has beaten the S&P 500 by nearly 1% per year on average.

  • YTD Return:   7.08%
  • Expense Ratio (net): 0.22%
  • Morningstar Rating  ★★★
  • Morningstar Risk Rating     ★★★★
  • Net Assets:     $2.89 billion
  • Yield:   1.55%

4. Walden Equity (WSEFX)

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, alcohol or tobacco concerns.


Returns have beaten the S&P 500 consistently for five years. It keeps at least 80% of its assets in equity securities and focuses on large-cap companies. 

  • YTD Return:   4.89%
  • Expense Ratio (net): 1.00%
  • Morningstar Rating  ★★★★
  • Morningstar Risk Rating     ★★
  • Net Assets:     $184.08 million
  • Yield:   0.88%

5. Domini Impact Equity Investor (DSEFX)

This fund has the highest expense ratio on our list. It invests in mid-cap and large-cap companies, and may invest in companies outside of the United States. The fund also invests in futures and options.

Domini has established its own social and environmental criteria for measuring companies. In addition to ESG screening, the fund looks for companies that are involved in their communities, support employee well-being, and show concern for ecosystems.


The fund has created its index of companies to choose from, and has successfully kept up with the returns of the S&P 500.

  • YTD Return:   5.12%
  • Expense Ratio (net): 1.14%
  • Morningstar Rating  ★★
  • Morningstar Risk Rating     ★★★★

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 our 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 are dedicated to a complete portfolio of responsible companies.
