Weitz 13F (2026 Q1): Omaha Quality-Value, Anchored by Berkshire

Omaha value, with Berkshire at the center

Wallace Weitz built Weitz Investment Management in Omaha into one of the more respected names in American value investing, close enough to Berkshire Hathaway's home that Weitz himself is sometimes described in the same value tradition. It is fitting, then, that the firm's largest holding in its 2026Q1 13F is Berkshire Hathaway itself, at 9.33% of reported value. The filing shows about $1.43 billion across 49 positions, a focused, quality-tilted value book that favors durable, well-capitalized businesses over speculative growth.

Below Berkshire, the portfolio reads like a curated list of high-quality compounders: Alphabet at 6.54%, Danaher at 6.32%, Visa at 5.60%, Mastercard at 5.13%, Aon, Microsoft, Meta, Thermo Fisher, and Vulcan Materials. This is value investing of the quality persuasion, owning excellent businesses bought at sensible prices, rather than deep-discount bargain hunting.

A focused book with a steady hand

With 49 positions and the top five accounting for roughly a third of value, Weitz runs a focused portfolio that expresses real conviction without the extreme concentration of a single dominant bet. The structure, a meaningful Berkshire anchor followed by a cluster of payments, life-science tools, and technology franchises, reflects a manager comfortable owning quality across sectors and holding it through cycles. Most of the top names were held essentially flat this quarter, with the notable exception of a 16% increase in the Microsoft position, the clearest active addition in an otherwise steady book.

Reading the gradual asset decline

Reported value fell about 15% on the quarter and has eased from roughly $1.9 billion two years ago to $1.43 billion now, a gradual downward drift. For a firm whose book stayed largely stable position by position, a decline of that shape is most consistent with steady net outflows plus market movement rather than any wholesale repositioning, the assets are slowly shrinking while the strategy stays put. As always, that makes the composition and the marginal moves more informative than the headline total: the book remains a quality-value core anchored by Berkshire, and the one decisive action was adding to Microsoft.

What a quality-value filing offers

Weitz's 13F is a useful read for investors who want value investing without deep-value discomfort. The holdings are recognizable, financially strong businesses, the kind that rarely look statistically cheap but compound reliably, and the Berkshire anchor signals a manager who respects durable capital allocation. The takeaway from this quarter is continuity: a focused quality-value book held steady, a gradual asset decline driven by flows rather than conviction, and a single clear vote of confidence in Microsoft. For idea generation, it is a window into where a long-tenured value manager is comfortable owning quality at today's prices.
