US Macroscope: Decomposing recent Russell 2000 outperformance and the second-half outlook for small caps

Goldman Sachs US Macroscope

Why have small-caps performed so well this year?

The Russell 2000 has returned 23% in the first half of 2026, outperforming the S&P

500 by 12 percentage points YTD. This represents one of the strongest semiannual

periods of small-cap outperformance during the last 30 years. During the past 12

months, the 18 percentage point excess return of the Russell 2000 vs. the S&P 500 ranks

in the 95th percentile since 1995. However, this recent strength reverses only a small

portion of the cumulative Russell 2000 underperformance of the past 15 years, during

which the S&P 500 has generated nearly twice its total return (680% vs. 375%).

Going forward, Russell 2000 index outperformance will likely fade in the second half

of the year, but the small-cap universe should remain exceptionally fertile ground

for alpha generation. Coming into 2026, the combination of an accelerating economy

and easing Fed created an ideal backdrop for small-caps. Those macro dynamics appear

less favorable in the back half of the year. In addition, the AI trade has been a major
