Berkshire Hathaway keeps adding to its bet on beaten-down homebuilder Lennar, lifting its holding to 11.2% this week — but the pace of its accumulation has cooled sharply, according to an SEC filing disclosed late Wednesday.

The filing shows Berkshire bought $53.6 million of Lennar's Class A shares plus $329,000 of the super-voting Class B shares across Monday, Tuesday and Wednesday. The total position now stands at 26.6 million shares, worth roughly $2.1 billion at Friday's closing prices.

What stands out is the deceleration. From September 17 through 25, Berkshire spent almost $349 million picking up Lennar shares, buying on six out of seven sessions — roughly $58 million a day on average. So far this week, the daily clip has held under $18 million through Wednesday. And because no fresh filing had appeared by Friday night, Berkshire appears to have sat out Thursday, which would pull the four-day average down to about $13.5 million. Whether Friday saw any activity stays unknown until Monday's filing deadline.

Why it matters

Berkshire's Lennar buildup is one of the year's quieter big-money stories, and the slowing pace is the first sign it may be getting more price-sensitive. The accumulation has been relentless: starting from 7.2 million shares when 2025 closed, rising to 10.3 million after the first quarter, then 13.4 million after the second — a 5.4% holding worth roughly $1.2 billion — and now 26.6 million, roughly double the share count since June.

Crossing the 10% ownership line in mid-September changed the game: Berkshire now has to disclose additional purchases within two business days instead of reporting quarterly, which is why we can track the slowdown in near real time.

The backdrop is ugly. The Mortgage Bankers Association puts the average 30-year fixed rate at 7.30% after six straight weekly increases — the highest since late 2023 — and house-price pressures are squeezing buyers on both sides. Morgan Stanley opened coverage on Lennar Thursday with an underweight view and a $65 price objective, nearly 19% below the $79.81 close. The shares slipped 2.8% that day.

What to watch

  • Monday's SEC filing deadline: it will reveal whether Berkshire bought anything on Friday and confirm the week's true daily average.
  • The $65 Morgan Stanley target: Lennar sits about 19% above it at $79.81; more sell-side coverage could test that gap.
  • Mortgage-rate direction: six consecutive weekly increases have pushed rates to 7.30%; any reversal would relieve homebuilders fast.
  • Berkshire's broader housing push: this stake-building follows the $6.8 billion Taylor Morrison acquisition closed in July, so housing is a deliberate theme.

MarketRadar take

The accumulation timeline tells the real story. Berkshire has nearly doubled its Lennar share count since the end of June, buying into weakness as the stock slid toward its 52-week low. At roughly $79.81, Lennar trades more than 40% below its 52-week high of $133.76 and only about 5% above the $75.7 year low — classic Berkshire territory: a large, cash-generating business at a depressed price. But the slowdown in daily buying suggests the bid is becoming more selective, not unlimited.

Context matters for sizing: the $2.1 billion Lennar position is barely 0.6% of Berkshire's $365.5 billion cash pile, so Berkshire could easily accelerate again. Until the Fed's hawkish stance reverses and mortgage rates roll over from 7.30%, though, Lennar's fundamentals face the headwind Morgan Stanley just priced in. Our read is neutral — one of history's best long-term buyers keeps accumulating, but the near-term tape belongs to the bears.
