Greenhaven Q1 2026: Wachenheim's 46% Homebuilder Bet

Most institutional 13F filers spread their capital across hundreds of names. Greenhaven Associates does the opposite. Edgar Wachenheim III's firm reported $6.07 billion across just 27 positions for the first quarter of 2026 — and more than four-fifths of that capital sits in its ten largest holdings. This is not a diversified book that happens to be tilted; it is a high-conviction wager on a handful of theses, run by one of the more durable contrarian value investors of the last four decades. Two ideas dominate everything: General Motors at the very top, and an enormous, deliberate bet on American homebuilders.

The top of the portfolio makes the concentration immediate. General Motors is the single largest position at 15.37% of assets ($933.2 million), narrowly ahead of Lennar at 15.21% ($923.3 million). Behind them sit Toll Brothers (12.69%), PulteGroup (10.65%), and D.R. Horton (7.84%). Add the four homebuilders together and they account for roughly 46% of the entire fund — and with smaller builder lines like Meritage and Taylor Morrison included, the housing sleeve approaches half the book.

The homebuilder thesis, in one portfolio

Greenhaven's housing concentration is not a cyclical trade timed to a rate cut. Wachenheim's argument is structural: over the past decade, homebuilders quietly transformed from capital-intensive, asset-heavy businesses that owned their land into asset-light operators that control land through options. That shift freed up enormous cash flow, which the builders have funneled into debt reduction and aggressive share repurchases. The market, in this view, still prices the group through the lens of its boom-and-bust past — assigning cyclical multiples to what have become steadier, cash-generative compounders.

The position sizing tells you where Greenhaven's conviction is strongest. Lennar was the one core builder the firm added to in the quarter, lifting its share count about 5% even as the stock lagged peers — Lennar's fiscal Q1 2026 revenue fell 13.3% year over year and missed estimates, the kind of stumble that creates the entry point a contrarian wants. Toll Brothers, by contrast, was held roughly flat after a quarter in which it beat estimates, raised full-year guidance, and lifted its dividend. PulteGroup and D.R. Horton were also left untouched. The pattern is classic Wachenheim: add to the lagging name with the better risk/reward, sit tight on the winners.

For readers tracking the individual names, the builder cluster spans Lennar, Toll Brothers, PulteGroup, and D.R. Horton — four of the five largest publicly traded U.S. homebuilders, owned together as a single thematic position rather than a hedge against one another.

Concentration that would make most managers uncomfortable

The math of Greenhaven's book is the story. The top five holdings command 61.7% of assets; the top ten reach 84.2%. That leaves the remaining 17 positions to split barely 15% of the fund between them. For a portfolio of this size, that is an extraordinary level of concentration — closer to a private holding company than a typical diversified equity fund.

What keeps that concentration from being reckless is the nature of the names. These are not speculative growth stories; they are large, liquid, cash-generative businesses trading at value multiples — General Motors, the homebuilders, plus industrial and distribution names like Oshkosh at 6.14%, Arrow Electronics at 4.48%, and Avnet at 3.98%. The one notable add outside housing was Baxter, where Greenhaven increased its share count about 34% to a 3.96% weight, alongside an energy-services position in Schlumberger. The book reads as a collection of out-of-favor, financially sound businesses — exactly the hunting ground a Graham-and-Dodd contrarian works.

Flows: trimming the top, pruning the tail

Quarter over quarter, Greenhaven's reported assets eased from $6.17 billion to $6.07 billion, a 1.6% decline, while the position count fell from 30 to 27. The firm exited four names — including Teleflex, Citigroup, and Robert Half — and opened a single new position in DNOW, a small energy-equipment distributor. The most consequential move at the top was the 17% reduction in General Motors shares: still the largest holding, but trimmed, suggesting Greenhaven took some profits or rebalanced after GM's run rather than abandoning the thesis.

Stepping back, the AUM trajectory shows a fund that has drifted down from a 2024 peak above $10 billion to the current $6 billion range — a function of position concentration meeting volatile underlying names like the builders, GM, and energy, rather than wholesale redemptions. With 27 positions and an 84% top-ten weight, Greenhaven's reported value will always swing with a small number of stocks. That is the cost, and the point, of running this kind of book.

What it signals

Greenhaven's Q1 2026 filing is a clean read on a specific, unfashionable conviction: that the homebuilders' asset-light reinvention is underappreciated, and that a cluster of cyclical-looking value names can be owned as long-duration compounders. The firm is voting with nearly half its capital. For investors using 13F data to find where genuinely active, discretionary money is concentrated — as opposed to index weight — a 27-stock book with 46% in one sector is about as undiluted a signal as the filings produce. The names to watch are the builders: if Wachenheim is right that the market is mispricing a structural change as a cyclical one, this is the portfolio positioned to capture it.
