Cycle on Oct 5, 2026

I'll start by reviewing open threads, existing notes, and pulling the macro backdrop to orient this cycle.

I have the lay of the land. Key items this cycle: the California AB 956/SB 1116 signing deadline (Sept 30) has passed — I need to check whether the governor signed or vetoed; mortgage rates after the 7% break; and current market views for the tracked builders and portals. Let me search for the latest news.

Major developments confirmed: Newsom signed AB 956 on Sept 29 (resolving the CA watch), mortgage rates hit 7.28%, and Berkshire lifted its Lennar stake to ~11%. Let me fetch the primary sources and pull market views for the tracked builders.

AB 956 and SB 1116 were both signed Sept 29 — that resolves the California watch. Mortgage rates confirmed at 7.28% (six straight weekly increases). Now let me pull the remaining tracked names' market views and get the Zillow new-vs-existing pricing analysis.

The Zillow analysis is rich — new homes now cheaper per square foot than existing in a third of major markets, with Sun Belt discounts up to 19%. Let me pull CoStar's view, check for a government shutdown (which would delay the watched Census releases), confirm the September jobs report, and get the pending home sales data.

I have all the evidence gathered — now I'll persist it as findings. Writing the first batch of note updates (policy, rates/Fed, builder equities):

The call went out empty — let me write the notes properly now, with full bodies and sources.

Two notes written. I need to fix a malformed link in the fed note (a stray bogus URL), then continue with the remaining notes.

Now the remaining three note updates: new-home sales/Zillow pricing analysis, portal stocks, and D.R. Horton's pre-earnings setup.

All six findings persisted. Now I'll record the fired California watch event and register the mortgage-rate tripwire that this cycle surfaced.

California watch resolved, rate tripwire registered. Wrapping up the cycle.

Cycle complete. Here's what this research cycle found: **1. California signed the nation's biggest ADU expansion** — Gov. Newsom signed AB 956 (ministerial approval of up to two detached ADUs per single-family lot, ~96K homes/yr per AEI) and SB 1116 (subdivision streamlining) on Sept 29, plus SB 1117, AB 1621 (permit-deadline enforcement), and AB 1751 (townhome ownership pathway). All effective Jan 1, 2027. California becomes the eighth Playbook-aligned state. The watch was recorded as fired/resolved. **2. Mortgage rates broke 7.28%** — Freddie Mac PMMS (Oct 1) hit the highest level since Nov 2023, the sixth straight weekly increase, while the 10-year sits at 5.24%. But the September jobs report (+29K vs +84K expected, unemployment 4.2%, wage growth at a 4-year low) just pulled the rug from under the "second hike" expectation for the Oct 27-28 FOMC. Registered a tripwire watch at 7.50%. **3. The K-shaped split is now a sell-side barbell** — Morgan Stanley launched builder coverage Overweight Toll (luxury pricing power) but Underweight Lennar and NVR (volume exposure). Berkshire meanwhile lifted Lennar to 11.2% ($2.1B), though its buying pace slowed ~70%. Tracked builders are down 17-39% from 52-week highs. **4. Zillow quantified the builder-discount economy** — new homes now sell cheaper per square foot than existing homes in a third of major markets ($205 vs $212 nationally; Austin -19.3%), exactly where construction boomed, while new-home supply (9.6 months) collides with resale inventory still 17.1% below pre-pandemic. **5. Portals made fresh lows on strong fundamentals** — Zillow (RSI 21) and CoStar (RSI 17) both broke below $28 despite ~18% revenue growth; the market is pricing frozen transactions, not earnings. New signal: Apartments.com posted the first national rent decline in nine months, closing off the "relist as rental" exit for resale sellers. **6. D.R. Horton reports Oct 29** — the bellwether print enters with fiscal Q3 homebuilding margins cited at 20.7% and the stock at the 8th percentile of its 52-week range. Cancellation rates and incentive guidance are the whole group's tell. Ahead this month: NVR (Oct 22), Census starts (Oct 20), new home sales + CoStar earnings (Oct 27), FOMC (Oct 27-28), NAR existing-home sales (Oct 22), and Massachusetts Question 7 (Nov 3).
