Small Caps Rout S&P 500: Time to Buy VTWO?
💡 Key Takeaway
Small cap stocks are outperforming large caps for the first time in years, with the Russell 2000 up over 20% in early 2026, and the trend may continue due to AI tailwinds and undervaluation.
Small Caps Surge Past S&P 500
Small-cap stocks have dramatically underperformed the S&P 500 over the past decade, with the large-cap index returning 323% versus the Russell 2000's roughly 200%. But in the first half of 2026, the tide has turned. The Russell 2000 surged more than 20% — its best first-half performance since 1991 — and is now beating the S&P 500 by the widest margin since 2003.
Two main drivers are behind this shift. First, small caps were historically undervalued relative to large caps at the start of 2026, trading at about 18 times forward earnings compared to the S&P 500's 26 times. Second, the AI boom is finally trickling down to smaller companies. Suppliers, chipmakers, and other 'picks and shovels' AI plays are seeing earnings estimates rise sharply — from 23% growth to 38% for 2026.
The last time the valuation gap was this wide, in 1999, small caps outperformed for over a decade. While history doesn't repeat exactly, the current setup suggests the outperformance could persist.
Why This Small Cap Rally Matters for Investors
For years, investors who focused solely on large caps, especially the Magnificent Seven, enjoyed outsized returns. But the tide is turning. Small caps now offer a compelling value proposition, trading at a significant discount to large caps. The earnings growth fueled by AI infrastructure spending is broad-based and sustainable.
If this trend continues, investors heavily concentrated in large caps could miss out. The Russell 2000's earnings momentum and relative cheapness suggest there's still room to run. Moreover, the AI tailwind is expanding beyond mega-caps, benefiting smaller companies that provide critical components and services.
For retail investors, this is a reminder to diversify. Small cap exposure could provide a buffer if large cap valuations compress. The outperformance may last years, as it did after the 1999 valuation gap.
