Are you looking for the next big thing in the stock market? There’s a chance it’s hiding among the small caps, because these smaller companies often remain overlooked by investors. One way to gain exposure to the entire segment of the market is to buy a small-cap ETF.

What is a small-cap ETF?

A small-cap ETF is an exchange-traded fund that invests in the market’s smallest companies through what are called small-capitalization, or small-cap, stocks. Small-cap ETFs give you an easy way to buy the small-cap “haystack” rather than search through it for the high performers.

Small-cap stocks may sound small, but they’re not usually that tiny. The total value of all their shares outstanding is typically between a few hundred million dollars and a few billion dollars. That’s small for the stock market, though, where market capitalization can hit around a trillion dollars.

Investors like small caps because they can offer higher potential returns than large-cap stocks, which are typically represented by the S&P 500 Index. However, because they’re smaller and have fewer financial resources, they’re often riskier and more volatile, too.

Because of these risks, investing in individual small stocks is better left to more advanced investors. But even newer investors can buy a basket of these companies through a small-cap ETF and take advantage of the potential higher returns in undiscovered small stocks.

Pros and cons of investing in small-cap ETFs

Investing in small-cap ETFs offers a lot of advantages, but it’s not without some drawbacks as well. Here are the most significant pros and cons of investing in small-cap ETFs:

Pros of small-cap ETFs

  • High-growth potential: Small-cap ETFs give you access to the potential for high growth that generally comes with these types of companies.
  • Diversified exposure: An ETF lets you buy a diversified portfolio of small caps, reducing your risk versus owning just a few stocks.
  • Low cost: Many ETFs charge low expense ratios for these benefits.
  • Less work: Unlike investing in individual stocks, where you’ll need to do a lot of work to analyze your stock, buying an ETF allows you to get in without the same work.
  • Easy to plug into a portfolio: Need some small-cap exposure in your portfolio? Just add a small-cap ETF and you have instant exposure.

Cons of small-cap ETFs

  • High performers grow out of the sector: The best small caps expand so fast that they grow out of their small-cap label, meaning funds often must sell them as the companies become more successful.
  • Narrow diversification: Because small-cap ETFs are focused on just one sector, they won’t protect against risks to small caps as a whole. So if investors shift away from small caps to large caps, for example, this kind of ETF won’t offset that risk.
  • Higher volatility: Small caps are riskier than large caps, so even a diversified investment such as a small-cap ETF can be more volatile, too.

Bottom line

Small-cap ETFs are an attractive way to invest in some of the market’s fastest-growing companies at low cost without the same risks of buying individual stocks. But like all investments in the stock market, they aren’t without risk and other drawbacks.
