Small Caps Aren't Dead — They're Misunderstood

Small-cap stocks have provided a return pattern quite different from large-cap stocks. Typically, small caps either race ahead of larger companies or else fall behind. They’re rarely in synch.

People explain the long-term outperformance in many different ways:

  • Smaller firms have more risk

  • Smaller firms are more illiquid

  • Investors have more confidence in, or knowledge about, larger firms, driving their prices up and returns down

  • Smaller firms are less closely followed by analysts and the market for them is less efficient

However, the cyclicality or lack of synchrony between large- and small-cap stocks makes it hard to exploit this premium. While the Fama-French small cap index outperformed the S&P 500 by a healthy 1.04% per year compounded from July 1926-June 2025, resulting in 2-1/2 times as much (see Exhibit 1) ending wealth over nearly a century, this outperformance has been so inconsistent that small-cap investors can experience very long periods of drawdown relative to large-cap benchmarks.
