A look at deep diversification in small-cap value investing. Royce & Associates, the small-cap specialist founded by Chuck Royce, reported a $10.13B U.S. equity book for the quarter ended March 31, 2026 (Form 13F-HR, accession 0000906304-26-000094, filed 2026-05-12). It is one of the most diversified portfolios in all of 13F data: the largest single position, infrastructure-products maker Arcosa (ACA), is just 1.36% of the book, and the ten largest holdings together make up under 10%. The remaining 90% is spread across hundreds of small-cap names. That structure is the strategy. Royce has specialized in small-cap value investing for decades, and small-cap investing demands breadth — individual small companies are riskier and less liquid, so spreading across many of them is how a manager controls risk while hunting for undervalued gems. The book reads like a tour of overlooked industrial and specialty names: Quaker Chemical (KWR), JBT Marel (JBTM), ESCO Technologies (ESE), ESAB, and UFP Industries (UFPI) — the kind of profitable, under-followed small-caps that rarely appear in megacap-dominated filings. Diversification as a small-cap discipline With the top ten under 10% of the book and no position above 1.4%, Royce's portfolio is the opposite of a concentrated, high-conviction book. MKS Instruments (MKSI), SEI Investments (SEIC), and a long tail of small industrials, specialty chemicals, and niche manufacturers fill out the holdings. This breadth is essential in small-caps. Because any single small company can stumble or prove illiquid, a small-cap value manager spreads capital widely so that the portfolio's return comes from the aggregate, not from a handful of names. It is the same diversification logic taken to an extreme that fits the asset class. A window into small-cap value Royce's holdings are a useful map of where a dedicated small-cap value manager is finding opportunity — heavily in industrials, specialty chemicals, and niche manufacturing, the unglamorous corners of the market where undervalued small companies tend to cluster. Because the book is so diversified and turns over modestly, no single position drives it. The signal in a Royce 13F is structural — the small-cap, deep-diversification approach — more than any individual holding. What it means for 13F readers Royce is the clearest example in large-cap 13F data of a hyper-diversified small-cap value book. It is a reminder that not every large filer is a concentrated bettor — some win through breadth and discipline in an asset class that rewards it. Read it for the small-cap value map it provides, not for individual stock picks. Track the firm's quarter-over-quarter holdings on the Royce & Associates filer page. FAQ What is Royce & Associates?
