Day narrative: A split tape with a clear personality — crude cratered on Strait of Hormuz diplomacy, which gutted energy and dragged the Dow red while the AI complex powered the Nasdaq Composite to a second straight record close at 27,244.28. Breadth was better than the headline flat S&P suggested, with the Russell 2000 up 0.79%.
Sectors: Best Technology/Semis (+1%+) · Worst Energy (XLE -2%, WTI -5%)
Movers:
• MU +4.85% — memory melt-up continues above $1,000; Goldman raised its target into the Sept 30 print on HBM demand
• MDB +5.0% — second big day running as Atlas growth and a 308% free-cash-flow jump keep the AI-database bid alive; investor day next Tuesday
• ADBE -4.5% — the AI-disruption discount won't quit; stock's now down roughly a third on the year ahead of a December CEO handoff
• ASML +2.14% / TSM +1.54% — semicap and foundry caught the same updraft as the memory trade
• VKTX +25% — obesity data showed 22% weight loss, the day's biggest single-name pop outside tech
• Majors ex-oil: Exxon and Chevron each off about 3% as crude slid
After-hours / Earnings:
• IONQ +6.0% AH at $43.20 — quantum names catching a late bid on the SDT partnership and raised FY26 guidance of $450–460M

Macro:
• Richmond Fed's Barkin said inflation shocks "aren't proving to be short-lived" and left the door open to more hikes beyond last week's September 16 move
• Iran signaled openness to reopening the Strait of Hormuz within seven days; Trump indicated any U.S.-Iran deal lands after the November midterms — crude bounced off the lows as that timeline stayed fuzzy
• Internals still soft under the surface: only about 31% of S&P 500 members are above their 50-day, and nine of eleven sectors are lower on the month
• AI IPO watch: Anthropic reportedly pushing its listing to November at a valuation investors peg near $2T; OpenAI has punted to 2027 while discussing a round near $1.2T. Neither is public — headlines only
Tomorrow: Light data docket — the week is thin on releases and thick on Fed speakers, with roughly ten central-bank appearances across the week and about a dozen small-cap earnings Wednesday. The real marker is Micron's fiscal Q4 on September 30, with consensus near $31.30 EPS on $50.62B revenue. Watch crude at the open for the Hormuz follow-through.
