The Russell 2000 has risen 43% since late May, outpacing the S&P 500. The AI capex cycle is pulling smaller suppliers along. Q2 earnings in July will test whether the rotation has legs.
Small-cap stocks have outpaced their larger peers since late May. The Russell 2000 is up 43% against a 30% gain for the S&P 500. The gap has widened in recent weeks as investors rotate out of megacap tech names that dominated the first half of the year. The rotation out of tech has accelerated, with the Nasdaq shedding ground (read more: Nasdaq Sheds 1.15% as Tech Rotation Fades).
The shift reflects a growing view that artificial intelligence benefits may extend beyond the largest cloud and semiconductor companies. The argument goes that the AI capex cycle – the hundreds of billions committed by megacap tech firms to data centers and infrastructure – flows through supply chains that include smaller manufacturers and logistics providers. A single contract for a specialized component or cooling system can have an outsized impact on a company with a market cap under $5 billion. For a megacap supplier, the same deal barely moves the needle.
Valuation also supports the rotation. The S&P 500's concentration in its top seven stocks has pushed their average price-to-earnings multiple above 30 times forward earnings. The Russell 2000 trades at roughly 18 times, leaving more room for multiple expansion if earnings materialize. Fund managers surveyed by Bank of America in June cited small-cap value as their most underweighted segment. That positioning can fuel rapid inflows when sentiment turns.
The rotation carries real risks. Small caps carry higher leverage and less pricing power than large caps. That makes them more sensitive to an economic slowdown. The Russell 2000 includes many unprofitable companies that depend on cheap financing. The Federal Reserve has signaled no rate cuts before December at the earliest. A recession would hit small-cap earnings harder than the S&P 500's more diversified profit base.
The next test comes in July, when second-quarter earnings reports will show whether the revenue uptick is real or just inventory restocking. If small-cap earnings confirm the trend, the rotation has room to run. If they disappoint, the Russell 2000's recent gains could prove fragile.
