Thematic exchange-traded funds, or ETFs, allow you to invest in a number of the hottest trends and industries—from blockchain to cloud computing, and clean energy to cybersecurity. Thematic ETFs are an easy way to play a trend rather than trying to pick a winner, allowing you to ride the wave that’s carrying the whole sector.
What Is a Thematic ETF?
A thematic ETF is a fund that offers the opportunity to invest based on a particular theme, such as climate change or artificial intelligence. The ETF then holds companies that should benefit from that trend.How a Thematic ETF Works
While ETFs first began as a cheap way to invest in the Standard & Poor’s 500 Index, they’re now a way to buy slices of any “exposure” you want. Looking for a specific country, industry or investing style? It’s a good bet there’s an ETF doing what you’re looking for. For example, new thematic ETFs get you a slice of red-hot industries.Thematic ETFs allow investors who don’t want to do all the analytical work on individual companies to simply buy the industry or trend. So if you see the potential in cloud computing, you can buy the ETF and get a diversified cross-section of the industry at low expense and hassle.
Most ETFs work by replicating a specific weighted index of stocks, and thematic ETFs are often no different. They’ll buy whatever stock is in the index and weight it accordingly in the portfolio. By buying one share of the ETF you’re buying a stake in all the companies in the fund, gaining quick exposure to the theme and a narrow diversification across the companies there.
Thematic ETFs are somewhat more expensive than some of the most popular index ETFs such as those based on the S&P 500. Fees on those popular funds can run less than 0.1 percent per year. In other words, you’ll pay $10 for every $10,000 you have invested in the fund.
While thematic ETF fees may be pricier than these cheap funds, they’re largely in line with the average expense ratio. Typically they’ll charge somewhere between 0.5 and 0.75 percent, meaning you’ll ultimately spend between $50 and $75 each year for every $10,000 invested.
If there’s a downside, the fund could be seriously hurt if something hits the sector or investors decide they don’t like it, and a thematic ETF’s narrow diversification won’t help reduce this risk.

Pros and Cons of Thematic Investing
Thematic ETFs are popular for a number of reasons, but they also have some drawbacks. Here are some of the most important pros and cons of this approach.Pros of Thematic Investing
- Flexibility —Thematic ETFs offer investors a way to invest in a targeted “slice” of the market quickly and then sell it just as easily if they think the opportunity has run its course.
- Diversification —Thematic ETFs may offer narrow diversification (all companies in a given industry) or broader diversification (companies across industries), but either way they put your eggs in more than one basket, reducing your risk.
- Ease —Rather than needing to research and buy multiple stocks, you can know less about the individual companies and get in and out of the market with one transaction.
- Low cost —You’ll pay a fee to the fund company running the ETF, but it’s often not so expensive for the diversification and expertise offered by the manager.
Cons of Thematic Investing
- Higher risk than more diversified funds —A thematic ETF may be exposed to certain risks—such as declining multiples on growth stocks or specific sector risks—that make them riskier than more broadly diversified funds such as an S&P 500 index fund.
- Volatility —Higher risk can translate into higher volatility, both on the upside and downside, especially for narrowly diversified funds.
- May need to more actively manage —If you’re trying to use thematic ETFs to play a hot trend, you may want to actively manage them more so than you would for a typical broadly diversified index fund such as the S&P 500, where passive investing is a better approach.
