There’s a powerful trend emerging in the investing world. Investors are building portfolios based on their morals and values. Dubbed “socially responsible investing”, or SRI, these investors align their investments with their values by avoiding companies with poor environmental, social or governance practices.

Like their counterparts, sustainable investors also want to earn a good financial return on their investment. They don’t want to sacrifice performance for social impact. And these days, they don’t have to. For the last several years, the returns on socially responsible investments have risen sharply – and many are beating the S&P 500

What’s driving the boom in Socially Responsible Investing?

Socially responsible investing (SRI) funds have been enjoying increasing popularity, largely due to the emergence of “impact investing” – a feel good concept that started in the U.K.

The difference between the two is that socially responsible investing avoids investments that are inconsistent with the values of the investors while impact investing actively pursues a specific positive impact.

For example, funds that don’t invest in companies that make alcohol, tobacco, gambling and weapons are considered socially responsible investments. A more targeted approach, impact investing addresses specific issues like sustainability, women’s rights, the environment and more.

Just how popular is SRI?

In 1995, there were only 55 mutual funds that engaged in SRI, with $12 billion in assets. Today there are nearly 500, with assets exceeding $500 billion.

What’s In It for Investors?

Socially responsible investing looks a lot different than it did just a decade ago. As SRI has evolved, the advantages for investors are numerous:

• SRI investors now have more investing options, with the number of funds growing rapidly. There is also increased diversification of the investments within the funds themselves, which results in less risk to the investor.

• Investors can now invest in socially responsible Exchange Traded Funds (ETF). There are funds of various market capitalizations and investors can choose from domestic, foreign and global funds.

• Investors can select a fund whose strategy and social responsibility agenda are similar to that of their own social and financial objectives.

Socially Responsible Investing Is Beating the Market

Socially responsible investing no longer means you have to sacrifice returns on your investment. The once meager returns of socially responsible investments have improved considerably, even beating the S&P 500. Consider the following:

• The Index which tracks the equity performance of socially responsible funds, Focus iShares MSCI USA ESG Select Social Index Fund (KLD), has out-performed the S&P since 1990, with an average annual total return of 10.46% compared with the S&P 500’s 9.93%.

• Benchmark performance of the MSCI KLD 400 Social Index, which includes firms meeting high Environmental, Social and Governance (ESG) standards, has outperformed the S&P 500 on an annualized basis by 45 basis points since its inception (10.14%, compared to 9.69% for the S&P 500; July 1990 – Dec. 2014).

• A 2015 report by Morgan Stanley, Sustainable Reality: Understanding the Performance of Sustainable Investment Strategies found that “investing in sustainability has usually met, and often exceeded, the performance of comparable traditional investments.”

Not all SRI funds beat the index, but it is remarkable how closely most of them track the market as a whole.

Here are some ways to add socially responsible investing to your portfolio. At the time of this writing, I do not own a position in any of the funds mentioned in this article.

Socially Responsible Investing: iShares MSCI KLD 400 Social ETF

For investors looking for an easy way to add socially responsible investing to their portfolio, the iShares MSCI KLD 400 Social (DSI) is worth a look.

DSI posted a 35.5% return in 2013 — beating the S&P 500. DSI posted a 12.2% return in 2014, under-performing the S&P 500 by less than 2 points.

The ETF’s underlying index tracks 99% of all the stocks in the United States and includes firms with a variety of market caps. The socially responsible ETF currently tracks 400 different firms and charges 0.50% in expenses. Technology and health care firms make up the bulk of DSI’s holdings.

Socially Responsible Investing: iShares MSCI USA ESG Select ETF

Investors wanting to eliminate the volatility of owning smaller firms from their portfolios should consider the iShares MSCI USA ESG Select ETF (KLD).

The $350 million ETF includes U.S. large-cap and some mid-cap stocks which have been screened for positive SRI characteristics. It currently includes almost a hundred different stocks — with top holdings in 3M (MMM), Microsoft (MSFT) and renewable energy utility NextEra Energy (NEE). Expenses for KLD are also 0.5%.

The socially responsible investing fund has consistently posted solid returns over the last several years. In 2013, KLD posted a 31% return, which was slightly less than the benchmark index, although KLD had beaten the index for the past 5 years. In 2014, KLD posted a total return of 13.5%.

Socially Responsible Investing: Huntington EcoLogical Strategy ETF

The often overlooked Huntington EcoLogical Strategy ETF (HECO) focuses on various firms making efforts on environmental issues and sustainability. It’s a well-diversified, moderate risk, capital appreciation fund. HECO focuses on “ecologically focused companies”, firms that have positioned their businesses to respond to increased environmental legislation, cultural shifts toward environmentally conscious consumption and capital investments in environmentally oriented projects.

HECO holds more than 50 different companies including Starbucks (SBUX) and Texas Instruments (TXN).

The returns have been strong. HECO returned nearly 30% in 2013 and narrowly outperformed the benchmark in 2014. Expenses for the ETF are slightly high at 0.95%.

Final Thoughts

You don’t have to give up performance to invest with your conscience and make a difference.

Serious investors interested in socially responsible investing no longer have to sacrifice investment returns for their morals. And the easiest way to add SRI to your portfolio is an Exchange Traded Fund such as the funds mentioned above.
