How America’s underdogs are winning big

There’s a different kind of buzz in the US stock market this week, one that’s less about tech titans and more about the little guys. While headlines chase AI, rate cuts, and megacap volatility, a quiet rally has taken hold in small-cap stocks. The shift isn’t just about numbers, it’s a story of resilience, insider conviction, and sector rotation that’s shaping the market’s next act.
From sidelines to centre stage
Earlier this year, small-cap shares stumbled as investors piled into AI and big tech. But Q3 flipped the script. According to Royce Investment Partners, the Russell 2000 index shot up 12.4% in the third quarter, outpacing the 8% gain from larger stocks tracked by the Russell 1000. Micro-cap shares, those tiniest companies usually overlooked, surged 15.7%. “The highest returns went to the smallest stocks,” summarised Christopher Clark, a partner at Royce, noting the outsized performance when compared with Wall Street’s blue-chip darlings.
What’s behind this underdog rally? The answer is in the market’s evolution. Value stocks have bested growth stocks, while highly-leveraged and low-profit companies put high-grade competitors in the shade. In the words of Madison Investments strategist Ellen Worthington, “Sector rotation is alive and kicking. Small caps are running because investors want exposure to a more cyclical, high-beta part of the market”.
The market’s hunger for diversity is easy to spot. Across the Russell 2000, Materials, Industrials, and Communication Services powered the advance. Real Estate, Financials, and Consumer Staples lagged—mirroring wider movements seen during sector rotations. Worthington added, “When risk appetite improves, investors move out of safe havens and into areas where recovery can outperform expectations”.
Conviction and insider action
Insider activity, when senior management or directors buy their company’s shares, has surged. October saw a raft of executives acquire undervalued small-cap stocks, fuelling confidence that the rally is rooted in conviction, not mere speculation. At companies like Limbach Holdings and PCB Bancorp, insider buying supported the market’s faith, with discounts to fair value as high as 47.3%. “Insider buying signals belief in future growth,” said Andrew Holt at Beacon Pointe Advisors. “It’s a green light for outside investors looking for signs that value isn’t just on paper.”
The numbers back him up. While small-caps are up 10.4% year-to-date, large caps have eked out 14.6%. But dig deeper and the lowest-return-on-invested-capital companies outpaced their highest-quality peers by more than 500 basis points. In a market where earnings surprises and economic recovery look patchy, small caps have emerged as a portfolio’s shot at alpha.
Echoing this optimism, Wells Fargo’s latest commentary encourages investors to “pick stocks based on long-term return of capital trends, not just short-term headlines”. It’s advice perfectly suited to a market where the little guys are writing their own comeback story.
The US stock market isn’t just about Silicon Valley or monetary policy moves, it’s also about unsung winners. As sector rotation and insider conviction give small caps a voice, America’s smallest companies may well be setting the tempo for tomorrow’s market narrative.
