With the 10-year government borrowing rate at a 19-year high, mortgage costs are punishing buyers and homebuilder stocks like Lennar have slumped — that's the bear case everyone can see. But Buffett is famous for buying solid businesses exactly when sentiment is worst, and Berkshire has nearly doubled its Lennar stake since July. When the world's most patient value investor is adding while everyone else flees, the downside is likely more priced in than the upside. A staged long entry lets you average into capitulation and ride any yield stabilization, which would be a double catalyst for housing stocks.

With the 10-year government borrowing rate at a 19-year high, mortgage costs are punishing buyers and homebuilder stocks like Lennar have slumped — that's the bear case everyone can see. But Buffett is famous for buying solid businesses exactly when sentiment is worst, and Berkshire has nearly doubled its Lennar stake since July. When the world's most patient value investor is adding while everyone else flees, the downside is likely more priced in than the upside. A staged long entry lets you average into capitulation and ride any yield stabilization, which would be a double catalyst for housing stocks.

Verdict: Wait — Buffett's Lennar bet is real, but the entry isn't live yet
The verdict: wait — this is a watch-list setup, not a live signal. The single strongest point for the idea is the smart-money signal itself: filings as of June 30, 2026 show net open-market insider/filer buying of roughly $348.8 million in Lennar, with Berkshire per CNBC adding to a stake it has nearly doubled since July. The strongest point against is that the thesis's centerpiece is also its weakest fundamental — Lennar's Q2 (ended May 31, 2026) net margin is just 3.8% and free cash flow is negative $303.2 million after two straight negative quarters, while the 10-year yield per CNBC sits near a two-decade high. The trade mechanics reinforce patience: the entry needs daily RSI (14) at or below 30, and none of the three names is close (LEN 55.4, DHI 54.7, PHM 49.1), with no robust parameter setup established because the optimization data was incomplete. What would flip it: a Lennar report around late December 2026 showing positive free cash flow — or a further Berkshire increase disclosed in the mid-November 2026 ownership snapshot — would strengthen the case even before a technical trigger. Meanwhile, PulteGroup's offsetting signals (net insider selling of about $1.3 million, free cash flow swinging to negative $12.9 million) argue for skepticism on that leg specifically.
Trade now
Nothing in this setup is live today — this is a wait-for-oversold plan, not an active signal. The idea goes long DHI, LEN, or PHM only when the daily 14-day RSI reaches 30 or below. Right now none of the three is close: DHI sits at 54.7 with the stock at $141.51, LEN at 55.4 at $82.15, and PHM at 49.1 at $119.85. That is roughly 25 RSI points of cooling needed on LEN, the thesis's centerpiece name, before the trigger comes into range. One honest caveat: the entry rule set also includes an overlapping condition requiring RSI to be above 30 on the same bar, which the research author has flagged as likely too tight and awaiting a re-run — so treat the exact trigger level as provisional until that work is done. The risk mechanics are simple and fixed. Every position carries a stop at a 2.4% loss from entry and a profit target at 4.9% — an effective reward-to-risk of roughly 2 to 1 — with position sizes capped at 25% of capital per name and sized off fixed risk. Because the stop and target are percentage-based, your actual price levels depend on where the entry prints: a LEN entry at $82.15, for example, would put the stop near $80.15 and the target near $86.15. The idea argues a staged long entry lets you average into capitulation while Berkshire is adding to Lennar — but the rules say patience here, not anticipation. What waiting means concretely: set alerts on the daily RSI for all three tickers at 30, and do not pre-position. Note also that no robust parameter setup was established for this strategy — the parameter search could not be completed because market data for DHI and PHM was incomplete — so the published thresholds are the baseline, not an optimized set.
Buffett Is Buying the Dip — and the Cash Flows Back Him Up
The idea's core claim — that smart money is buying homebuilders while everyone else flees — gets direct support from the 13F-style ownership data. For the reporting period ended June 30, 2026, Lennar shows a net open-market insider/filer buying direction of roughly $348.8 million, per the CNBC report on Berkshire adding to a stake it has nearly doubled since July. That is the single most decision-useful fact in the file: the world's most patient value investor is adding size into a slump, which is exactly the behavioral signature the thesis says marks a priced-in bottom. The fundamentals are also turning, not deteriorating. D.R. Horton's Q3 (ended June 30, 2026) showed revenue up 22.1% quarter-over-quarter to $9.23B, net income up 39.7% to $904.9M, and free cash flow swinging from negative $449.7M in Q2 to positive $397.3M. Gross margin ticked up 0.72 points to 23.3%, and net margin climbed to 9.8%. PulteGroup posted a similar pattern in its Q2 (ended June 30, 2026): revenue up 16.9% to $3.98B, net income up 36.0% to $472.0M, net margin up to 11.9%. Even Lennar — the weakest of the three — grew revenue 20.0% sequentially to $7.94B and improved net margin to 3.8%. Cash generation remains elite relative to peers. In the latest full-year snapshots, D.R. Horton's $2.43B of free cash flow sits in the 99.8th percentile of 577 Consumer Discretionary peers, Lennar's $1.67B is in the 99.5th percentile, and PulteGroup's $739.8M is in the 97.3rd percentile of its Real Estate peer group. These are not distressed builders; they are cash machines whose stocks have been repriced by rates, per the CNBC piece on the 10-year yield hitting a nearly two-decade high. Shareholder returns back the quality argument too. All three raised dividends through the slump: D.R. Horton lifted its annual payout 12.5% to $1.35 per share for 2026, PulteGroup 18.2% to $0.78, and Lennar holds at $2.00 with a stable $0.50 quarterly. Management is also shrinking the float — D.R. Horton cut shares outstanding 1.48% in a single quarter to 280.7M, continuing a multi-year buyback run from over 316M shares in 2009. A staged long entry, as the idea proposes, is a rational way to average into that setup if yields stabilize. One honest scope note: the entry rules were evaluated on real daily bars but never triggered in the last nine months across 186 bars — this is a watch-list setup, not an active signal. That doesn't undermine the thesis; it means the oversold-reversal condition simply hasn't printed yet.
The Rates Wall That Berkshire Can't Buy Away
