Small-cap exchange-traded funds (ETFs) are designed to invest in a basket of stocks with relatively small market capitalizations. A small-cap company is generally one whose market value is somewhere between $300 million and $2 billion. However, small-cap ETFs are not necessarily restricted to that range, as evidenced by some of the holdings of the ETFs outlined below. Because of their size, small-cap stocks have strong, albeit often volatile, growth potential. A small-cap ETF can reduce the volatility associated with individual stocks while offering investors greater diversification.

Key Takeaways

  • The small-cap sector significantly outperformed the broader market over the past year.
  • The ETFs with the best 1-year trailing total return are CNBS, XSVM, and RFV.
  • The top holdings of these ETFs are class A shares of Silver Spike Acquisition Corp., class A shares of GameStop Corp., and Telephone and Data Systems Inc., respectively.
