Small-Cap ETF Outpaces S&P 500 in 2026: Should You Buy?

A small-cap ETF is beating the S&P 500 so far in 2026, but whether it belongs in your portfolio depends on your goals.

A small-cap exchange-traded fund is turning heads on Wall Street in 2026, delivering returns that have outpaced the benchmark S&P 500 index — a feat that has investors questioning whether the rally has more room to run or whether the window is closing fast.

Small-cap stocks have historically offered higher growth potential than their large-cap counterparts, but they also carry elevated risk and volatility.
