After years of watching mega-cap tech stocks hog the spotlight, small-cap companies are finally getting their turn. And unlike the brief head fakes investors have endured before, this rally might actually have legs.
The iShares Russell 2000 ETF (IWM) has been pushing to fresh record highs this month, outperforming its large-cap cousins in a reversal that feels almost unfamiliar after such prolonged narrow market leadership. According to a Thursday strategy note from 22V Research, the macro and fundamental case supporting U.S. small caps "remains intact," driven by structural forces rather than fleeting sentiment shifts.
Productivity: The Unsung Hero of the Rally
Here's the setup: strong productivity is allowing the economy to grow above trend without sparking inflation. That's a Goldilocks scenario that lets the Federal Reserve keep financial conditions loose, which naturally favors riskier assets like small caps over defensive plays.
"Strong productivity allows for above-trend growth without causing inflation," wrote Dennis DeBusschere, president and chief market strategist at 22V Research. "That allows the Fed to keep financial conditions easy and favors risk-on versus risk-off exposure."
This environment means the Fed can stay patient, with markets zeroing in on labor market data and services inflation as the primary policy wildcards. Even geopolitical noise—including recent tariff headlines—has increasingly been treated as buying opportunities rather than reasons to de-risk, according to 22V.
Why This Time Could Be Different
"The broadening-out of returns can last more than a month or two without being offset by tighter financial conditions," the firm noted.
On the fundamentals front, small-cap earnings revisions are now outpacing both their historical averages and the revisions seen in mid- and large-cap stocks. That's not what you'd expect if the economy were heading toward a late-cycle slowdown. Better yet, small caps started the year with beaten-down valuations after experiencing "significant multiple contraction" in 2025, even while their fundamental growth outpaced larger peers.
Regional Banks Are Quietly Telling a Recession-Free Story
Financials, especially regional banks, have been key contributors to small-cap strength. Bill Hebel, 22V's banks analyst, says the fundamentals remain solid and valuations attractive.
"Regional Bank fundamentals have been solid this quarter and relative valuations are attractive," Hebel said. He noted that the market's rationale for paying premiums for larger balance sheets, capital markets exposure, and card businesses has weakened considerably.
Perhaps most telling: "There has been a notable absence of conversations about credit health in earnings so far," Hebel added. When credit concerns aren't dominating bank earnings calls, it's a pretty good sign recession fears are overblown.
AI Might Be the Next Catalyst
Artificial intelligence could represent the next revaluation catalyst for small caps, especially as adoption extends beyond software into physical products.
Jordi Visser, 22V's AI specialist, believes 2026 could mark an inflection point. "The integration of AI into physical products is the major investment theme of 2026," Visser said, highlighting power providers, semiconductors, capital goods, and tech hardware as prime beneficiaries.
While small caps have traditionally lagged their larger counterparts in AI adoption, management teams are now increasingly discussing specific AI use cases on earnings calls. "The re-rating is still in its early innings," Visser said, suggesting that AI adoption could help small caps narrow the margin gaps that have favored large caps in recent years.
