Key Takeaways
Small- and mid-cap stocks have historically outperformed following periods of relative weakness, and recent performance may signal the early stages of a leadership shift.
Multiple tailwinds are aligning for the asset class, including attractive valuations, improving earnings growth, low investor positioning, and supportive domestic economic trends.
Opportunity is expanding, but selectivity remains critical, as wide performance dispersion across companies creates a compelling environment for active managers.
While U.S. large-cap equities have been the primary beneficiaries of the Magnificent 7 earnings boom and the AI-driven data center investment cycle over the past decade, we believe the backdrop over the coming years is increasingly favorable for U.S. small- and mid-cap stocks.
While large-cap dominance can appear persistent, history suggests that periods of leadership eventually rotate. Over the past century, following major small-cap market troughs, small caps have historically outperformed large caps by more than 14% annualized over the subsequent five years:
Recent performance may indicate that the cycle is beginning to shift. From June 30, 2025 through June 30, 2026, the Russell 2000 Total Return Index returned 40.78%, compared with 22.33% for the S&P 500 Total Return Index.
Going forward, there are several tailwinds that should benefit US small and mid cap companies vis a vis US large

incentives contained within the One Big Beautiful Bill (OBBB), may provide an incremental boost to domestic economic activity. Because small- and mid-cap companies generally derive a larger share of their revenues from the U.S., they may benefit disproportionately from these trends.
companies, which often face higher compliance costs as a percentage of revenues.
concentrated among larger companies. We believe improving financing conditions and strategic demand could
broaden acquisition activity across the small- and mid-cap universe over time.
Looking ahead, we believe one of the most compelling opportunities within the U.S. small- and mid-cap universe is the adoption of artificial intelligence to improve productivity, operating efficiency, and profitability:
One argument for investing in the U.S. small- and mid-cap universe to capitalize on AI adoption is to contrast it with investing in today's AI winners. Continuing to invest in AI providers and infrastructure companies effectively represents a relatively concentrated bet that the substantial capital spending programs of a handful of large technology companies will continue to support the current investment cycle. By contrast, investing in AI adopters allows investors to evaluate thousands of companies' efforts to deploy AI and identify the businesses best positioned to improve operating performance and shareholder value. While enthusiasm for the AI data center infrastructure buildout remains widespread, investors have increasingly begun to question some of the financing arrangements and interdependencies emerging among NVIDIA and the hyper-scalers supporting these projects. We believe the next phase of the AI investment cycle is likely to involve a much broader set of participants, with significantly greater dispersion in companyspecific outcomes, creating a larger opportunity set for active stock selection.
Another argument for investing in U.S. small & mid caps for AI adoption winners is seen by comparing the efficiencies that AI can drive across the market cap spectrum. While larger companies may realize greater absolute dollar savings from AI initiatives, smaller companies may experience greater percentage improvements in profitability due to their higher operating cost structures. The median Russell 2500 company has 29.8% SG&A expenses vs. 10.2% for the median Magnificent 7 company: a 5% reduction in SG&A would drive a larger earnings improvement for small/mid caps:
