Stock-market dispatch — 2026-09-15

Headless run (Tue). Research output, not advice — brain never trades. Marks are 2026-09-14 closes, Monday's cash session. The FOMC started today; the statement is tomorrow. Supabase upsert + push are performed by the wrapper, not this run.

Top of mind

The Federal Open Market Committee began its two-day meeting this morning. Kevin Warsh's statement, the SEP, and the press conference are still Wednesday, September 16, at 2:00 and 2:30 p.m. Eastern. Futures that jumped after Friday's CPI still sit around eighty-seven to ninety-three percent for a quarter-point hike, to 3.75–4.00 percent. A meeting's first day is not a reaction function. Schwab's last disclosed scenario still assumed a December hike. Conversion remains the words Warsh has to issue tomorrow. Do not graduate. warsh-higher-for-longer-to-brokerage-nii-rerate

Monday was a risk-off session in the names this book already owns as research: Micron fell 5.3 percent, Intel 5.6 percent, Constellation 7.1 percent, Vertiv 7.7 percent. ServiceNow was the exception, up 7.4 percent, with no new primary on the seat-SaaS chain. That is tape, not a re-rate. agentic-ai-seat-erosion-to-saas-rerate

Apple's Siri AI public beta is now live. The copy still describes usage limits and a future Apple fee — an Apple meter, not a disclosed payment from a frontier lab for default placement. Stay hypothesis. Do not graduate. apple-ai-aggregator-toll-to-services-rerate

FERC has still not ruled on the PJM backstop. The WuXi answer is still September 18. Intel still has no named outside 18A high-volume order. Elon restated Terafab as an Austin R&D line for Tesla and SpaceX, equipment on order, useful by the end of next year not at scale. That is crawl-walk-run, not a named wafer start. SemiAnalysis's Vera Rubin AgentX note (~67× TCO versus GB300; ~2× profit per gigawatt) does not merge AgentX versus Jalapeño. The AI-infrastructure cluster is already overweight, so today's new-chain budget did not add another name there — the twenty-fifth weekday in a row.

Strongest-conviction buys

Ranked shortlist (4c). Prices = 2026-09-14 closes, twelvedata. Monday session.

Undervalued candidates (today)

New chains to investigate (hypothesis-stage)

  • Aging US housing stock (median home now 42 years) → repair and remodel spend → Home Depot's Pro mix and exclusive house brands (industry estimates 15–25% of sales). Distinct from the homebuilders (new construction) and from grocery private label. Conversion bar: a Census or ACS age-of-stock print plus HD's disclosed Pro mix. Do not chase on a podcast. HD / LOW. aging-housing-stock-to-home-depot-repair-spend
  • HEL (hel-layered-iamd-to-lockheed-helios-mp-dopants) remains the open defense hypothesis from a prior Friday. Conversion bar unchanged: Helios revenue mix or a ytterbium offtake.
  • ⚠ Still no hypothesis page for the healthcare CDMO contradiction — twenty-third weekday. A still-silent docket is not a 2026 price series. Human call, not a silent downgrade. OMB BCOC list 2026-12-18. Next docket gate: September 18.

New theses (now active)

  • None. Zero graduations. 1 new company (home-depot), 1 new person (gwynne-shotwell), 1 new hypothesis. 0 new mechanisms (Terafab and Rubin were attach-only).

Updated theses (existing active)

Contradicted / weakened

  • None closed.
  • ⚠ UNRESOLVED CONTRADICTION, twenty-third weekday — Western CDMO pricing power vs a −15% realized mAb fill-finish series. Silence on the docket is not a price series. No conviction or status changed unilaterally — human call. biosecure-cdmo-scarcity-to-western-cdmo-pricing-power
  • ⚠ CUDA Step 2 is still an unmerged pair (AgentX vs Jalapeño InferenceX). The Rubin 67× note does not merge them. Conviction held.
  • 4e: 20 live positions, 3 flags < −10% — TJX −21.2% (low), PWR −15.7% (medium, healed), INTC −10.6% (medium, healed). 0 automatic calibrations. Digest as-of is still 2026-08-27. Best live: DNN +15.0%, MP +14.2%, STVN +11.5%. Worst cluster: energy-oil −7.3% — ⚠ twenty-fourth consecutive week the label mismatch is noted without being fixed: live rows CCJ/CF/NTR, not the refiners sitting 3–4 percent off the highs.

Open questions worth a human's eye

What I looked at

  • Run status: headless; steps 0.5–7 in-turn. Price fetch paced 8/min — 239 priced, 237 on 09-14 closes (SSNLF printed 09-11; CRNX 09-02). 0 rate errors (no 429s). ⚠ Skipped: ASE, BESI (plan-tier — twenty-sixth day; ASX / BESIY filled). GNKG, HXSCL, GEIS, ENT not re-fetched. Errors: 0992.HK / 6324.T / SMICY / YPSN.SW / NULL 404; CTRA 403. THS / BANB.SW / CDMO / CTLT not in the pull.
  • Breadth (2a): ai-infrastructure 44% ⚠ over (21 chains / 20 tickers, 66 live signals, 8 clusters) → net-new steered to thin verticals. Delivered: buckets #10 consumer, #11 transport, plus dated gates. Zero net-new ai-infrastructure chains, twenty-fifth consecutive weekday.
  • Research passes: 1 (event-day gates: FOMC day 1 / statement tomorrow / 18A / FERC / CDMO / truckload / grocery PL).
  • Ingestion veins (0.5–0.8): Podcast 2 transcribed (Acquired Home Depot; All-In Elon/Gwynne). Earnings 8× 8-K 99.1 HTTP 404 again (logged, continued; twenty-sixth day). Feeds: Fabricated Knowledge 08-13 still paywalled (twenty-fourth consecutive); Apricitas silent since 2026-05-03. Conferences: VLSI PDF 404; ISSCC 0; Hot Chips / IEDM already skipped.
  • Sources: 5 promoted + 5 ingested (stock-market; 3 also AI thread) → 1 new hypothesis, 1 new company, 1 new person, 0 new mechanisms, 0 graduations, 0 calibrations.
  • prospect-chains (2b): auto-drafted aging-housing-stock-to-home-depot-repair-spend (thin #10). HEL already drafted. CDMO contradiction still has no hypothesis page (twenty-third weekday, human call). Terafab / Rubin / robot-brain attach to existing spines — not novel. Cap honored. Did not establish-chain into AI-infra.
  • Valuation snapshots refreshed: 15 mechanism Close tables (plus 18A mark) to 09-14 closes.
  • Weekly ledger (4d): skipped (written Friday). Hypothetical inception re-mark still deferred (twenty-second week).
  • Signal feed (7): full active/armed set re-marked to 09-14 closes; as_of carried (still-no / attach-only / tape do not re-date TMO / CEG / MU / NVDA / NOW / WERN / MP / VLO / AAPL / SCHW / CAT). Feed committed; Supabase skipped by wrapper design.
