Analyst day on Oct 6 is the next catalyst. - MU: hold - Down 3.4% Monday on the OpenAI pause, despite Baird lifting its target to $1,520 and JPMorgan expecting a beat. FQ4 results Wed Sep 30 after close; options imply about an 8.5% move. - NFLX: hold - Down 1.4% Monday with no new company news. Recent downgrades over YouTube share remain the overhang; Q3 results Oct 20. - NVDA: hold - Up 2.6% Monday after a $150B buyback increase (total $235B through FY2028), the largest ever.

Mortgage rates around 7% keep volumes under pressure. - STRIPE: hold - No new round or tender reported; last mark is the February tender at $159B. - TSM: add - Down 0.9% Monday, holding up better than other chip names.

Previous closes match the Sep 25 figures supplied. Macro: S&P -0.55%, Nasdaq -0.8% midmorning on US-Iran tensions, Brent near $107 and higher Treasury yields. The China-may-allow-Nvidia-chips story for BABA was skipped because it is already in known_urls. No new Stripe round or tender found (last is Feb 2026 at $159B). OpenAI DevDay is still listed for Sep 29; no source says it was postponed despite the pause. Meta's 4% drop comes with the enterprise launch but has no clear single cause (the OpenAI pause, a New Mexico privacy verdict and AI subsidy scrutiny are also in the news). | US figures are intraday as of ~10:38am ET Sep 28. The SOX level differs by source (investing.com shows ~12,398, -2.14%; a search snippet gave a stale figure), so quote only the % move. Bloom's -8.6% Monday has no identified cause (the class-action lead-plaintiff deadline was Sep 28, and chips and AI power sold off broadly). SKHY -5.4%, ALAB -3.2% and TER -2.0% on the sector move, but their theses are unchanged, so those entries were not returned. AVGO, ASML, GEV and SE are roughly flat, with no new company news. No material BYD, Spotify or Cursor news since Friday: BYD traded at HK$77.70 on Monday, and Spotify set Q3 results for Oct 22 (not opened, so not listed). Keyence and Toyota: no company news; Nikkei -0.7%. China: Shanghai -1.7%; industrial profits growing but slowing. The WebSearch budget was exhausted mid-run, so watchlist checks relied on stockanalysis and Yahoo pages. The Axios Iran article returned 403; the Iran facts are sourced from the Yahoo live blog. | Silicon Data (opened Sep 29 00:40 AEST): H100 $2.70, H200 $3.33, B200 $5.87, A100 $1.57 all unchanged vs Sep 28; only B300 moved ($6.80 -> $6.78) and H100-hyperscaler +0.1%. No new CoreWeave/neocloud financing found since the Sep 24 convert close. DRAM spot inched up (DDR5 $57.83). Verified unchanged: OpenAI DevDay Sep 29 keynote 10:00 PT; RBA Sep 29 14:30 AEST (92-94% odds of +25bp to 4.60%); Micron Sep 30 14:30 MT (16:30 ET); US jobs Oct 2 08:30 ET (BLS); TSLA deliveries Oct 2 expected pre-market, consensus 454k (Visible Alpha), range 435-480k; CME H100/B200 futures still 'Oct 5, pending regulatory review' - no approval notice found.
