The Vanguard ESG U.S. Stock ETF tracks an index of U.S. stocks that are screened based on environmental, social, and governance (ESG) criteria. ESG funds are an increasingly popular segment of the ETF marketplace, offering values-driven investors a diverse portfolio of U.S. stocks without compromising their conscience. Vanguard’s is one of dozens, if not hundreds, of similar funds that have debuted in recent years. ESGV invests in hundreds of U.S. companies, including small-, medium-, and large-cap equities, but eschews the so-called sin stocks such as adult entertainment, alcohol, tobacco, and gambling. ESGV also excludes weapons makers, fossil fuel companies, and nuclear power. Not surprisingly, the elimination of fossil fuels giants means ESGV has a bit more of a tilt toward tech stocks than an S&P 500 fund, and has less of its portfolio in energy stocks. For investors looking to align their portfolio with their values, ESGV is a good low-cost option for U.S. equity exposure, though rivals also offer competitively priced options.
