The quarter's moves show a measured rotation: trimming Costco and Home Depot while adding 57% more Amazon. A long tail of names, a quality core that does the work Chilton Investment Company, the firm founded by Richard Chilton, has long pursued a high-quality growth approach: own well-run, financially strong businesses with durable franchises and let them compound. Its 2026Q1 13F lists about $4.26 billion across roughly 280 positions, but the breadth of that list is misleading. The top ten holdings account for more than half the reported value, and they share an unmistakable family resemblance, dominant, cash-generative companies with pricing power. The long tail of small positions matters far less than the concentrated quality core at the top. That core is led by Microsoft at 8.27%, Costco at 7.87%, Sherwin-Williams at 7.40%, Republic Services at 6.43%, and Mastercard at 4.76%, followed by Home Depot, Amphenol, Amazon, Cintas, and IBM. It is a roster of compounders, software, warehouse retail, paint, waste collection, payments, drawn from the kind of stable, high-return businesses that quality investors prize for their predictability. Concentration hiding inside a broad list It is worth pausing on the structure, because a 280-name filing can look like an index fund at first glance. It is not. With the top ten above 50% of value and clear weighting toward a handful of franchises, Chilton is expressing real conviction at the top while using the long tail for smaller, more opportunistic positions. When you read a filing like this, the right move is to focus on where the weight actually sits rather than being distracted by the sheer number of tickers. Trimming retail, leaning into Amazon Reported value fell about 11% from the prior quarter, and the share-count moves show a manager actively reshaping the quality core rather than simply riding the market. On the sell side, Chilton trimmed two consumer-facing names: Costco by 15% of shares and Home Depot by 18%, with a smaller cut to Republic Services. On the buy side, the standout was Amazon, lifted by 57% of shares, alongside a 12% add to Cintas. The pattern reads as a rotation within the quality universe, taking profits in richly valued traditional retail and reinvesting toward Amazon's broader platform and Cintas's durable business-services franchise. None of this disturbs the top of the book's character; Microsoft, Sherwin-Williams, Mastercard, Amphenol, and IBM were all held essentially flat. The activity is a tilt, not an overhaul, exactly what you would expect from a quality-growth manager fine-tuning rather than chasing. How to read a quality manager with a long tail The lesson from a filing like Chilton's is to weight what is weighted. A broad position count can mask a genuinely concentrated, high-conviction portfolio, and the meaningful signal lives in the top holdings and the share-count changes among them. This quarter, that signal is a measured rotation, out of expensive retail, into Amazon and business services, on top of an otherwise steady core of compounders. The asset decline reflects that trimming plus ordinary market movement rather than any abandonment of the strategy.

Chilton, founded by Richard Chilton, pursues a high-quality growth approach, owning well-run, financially strong businesses with durable franchises and letting them compound. Its 13F shows a broad list of names anchored by a concentrated core of quality compounders. ### How concentrated is Chilton's portfolio despite 280 names? Quite concentrated at the top. The roughly 280 positions total about $4.26 billion, but the ten largest holdings account for more than half of reported value, so the long tail matters far less than the quality core. ### What are Chilton's largest holdings in 2026 Q1? The top positions were Microsoft (8.27%), Costco (7.87%), Sherwin-Williams (7.40%), Republic Services (6.43%), and Mastercard (4.76%), followed by Home Depot, Amphenol, Amazon, Cintas, and IBM. ### What did Chilton buy and sell in 2026 Q1? It trimmed Costco by 15% of shares and Home Depot by 18%, with a smaller cut to Republic Services, while adding 57% more Amazon and 12% more Cintas, a rotation within its quality universe. ### Why did Chilton's reported value fall about 11%? The decline reflects the share-count trimming of names like Costco and Home Depot combined with ordinary market movement, rather than any wholesale change in strategy, since the top core was largely held flat. ### How should I read a 13F with hundreds of positions? Weight what is weighted. Focus on the top holdings and the share-count changes among them, because a broad position count can mask a concentrated, high-conviction core, and the long tail of small positions carries much less signal. --- Source: 13F Insight — https://13finsight.com/research/chilton-investment-13f-2026-q1 Author: Marcus Chen — https://13finsight.com/authors/marcus-chen Last updated: 2026-05-24T08:28:14.718Z
