Key Takeaways:
Small-cap stocks are outperforming their mega-cap peers at the fastest rate in decades, signaling a broadening of the AI-driven rally.
The Russell 2000 surged 22% in the first half of 2026, its best start to a year since 1991, as investors rotated from expensive chip stocks into smaller companies. The small-cap index beat the Nasdaq Composite by about 9 percentage points, the widest outperformance in that period since 2006.
"Investors are stepping back and asking where the next leg of alpha might come from," said Joshua Schachter, chief investment officer at Easterly Snow. "The market was missing a lot of interesting ideas with great valuations."
At one point last week, the Russell 2000 notched four straight record closes. The S&P 500 rose 9.6% in the first six months, while the Dow Jones Industrial Average gained 8.9%, its best first half since 2021. The Nasdaq Composite climbed more than 12%.
The rotation comes as cooling inflation and a softening labor market reduce the odds of a Federal Reserve rate hike, benefiting smaller companies that rely more on domestic revenue and floating-rate debt. Analysts project 54% earnings growth for Russell 2000 companies in 2026, more than double the rate expected for the Russell 1000.
The rally marks a departure from a market that for years has been dominated by trillion-dollar AI giants. While chip stocks such as Intel and Micron Technology powered the Nasdaq's first-half gain, the Philadelphia Semiconductor Index sank 6.3% on Wednesday and 5.4% on Thursday as traders questioned whether the AI frenzy could sustain its pace. Schachter has taken profits in semiconductor and AI names, rotating proceeds into healthcare, industrials and consumer-discretionary stocks. "They're great companies," he said of the chip makers. "But the stocks are just so expensive."
Small-Cap Earnings Boom Takes Shape
The earnings outlook for small-caps is a key driver of the rotation. Francis Gannon, a managing director at Royce Investment Partners, said the projected 54% earnings growth for Russell 2000 companies "is pretty strong, and it's just beginning. We have a bit of a run coming."
Among the biggest gainers in the S&P Small Cap 600 index last quarter: buy now, pay later platform Sezzle and restaurant chain Cracker Barrel. Semiconductor company MaxLinear surged more than 600%, while chip maker Vishay Intertechnology and AI-infrastructure business Penguin Solutions each more than doubled.
Still, the Russell 2000 contains chip stocks including Sandisk and Dell Technologies, meaning the index remains exposed to shifts in AI sentiment. "Some sectors are doing better than others," said Philip Blancato, chief market strategist at Osaic. "It really is a small portion of the index that drove these returns."
The combined market value of all companies in the S&P Small Cap 600 is $1.83 trillion, roughly the size of Broadcom. The index also faces a structural challenge: its annual rebalancing recently graduated some top-performing members to the large-cap Russell 1000.
Inflationary pressures have eased following the US-Iran peace deal, which lowered oil costs. Thursday's jobs report showed a cooling labor market, stirring hopes the Fed will hold off on raising rates. The 10-year Treasury yield stood at 4.457%, while Brent crude traded near $72.92 a barrel and gold held around $3,978.70 an ounce.
"Even a sliver of those investments rotating into smaller shares would make a big difference," said Keith Lerner, chief investment officer at Truist Advisory Services. "A little bit of good news has gone a long way for small-caps."
