Closes: SPX 7,507.65 (+0.9%) · NDX 29,022 (+1.5%) · DJI 52,258 (+0.8%)
Day narrative: Semiconductors hijacked the tape from the opening bell — memory stocks posted their strongest single-day run in weeks as SK Hynix's +14% Asian session lit the fuse and U.S. chip names never looked back. Software and cyber got rotated out hard, with Morgan Stanley dropping a double-downgrade on Adobe and Salesforce that set the tone for the losing side.
Sectors: Best Technology (XLK +2.8%, SMH ~+4%) · Worst Healthcare (Danaher −10.9% dominated the drag on weak bioprocessing outlook)
Movers:
• MU +12.2% to $970.82 — SK Hynix's Korean overnight blowout fed directly into U.S. memory names; Micron extended gains from last month's record earnings report
• AMD +8.0% — Broadest AI accelerator proxy outside NVDA; rode the chip tide as HBM demand reads stay strong
• ARM +6.1% to $279.76 — Design royalties are levered to every chip win in the sector; TSM's 2nm expansion added a tailwind
• TSLA +3.5% to $379.77 — AI/robotics reframe doing the work ahead of Wednesday's Q2 report; 480k record deliveries are already priced in, now it's margin time
• ADBE −3.0% to $227.77 — Morgan Stanley flipped to Underweight; same note hit CRM, and the whole enterprise software complex felt it
• CRWD −3.9% to $192.21 — No company-specific catalyst; just a brutal session to be a software name when chips are ripping 8–12%
After-hours / Earnings:
• No watchlist names reporting tonight. The AH tape is quiet — markets are holding breath ahead of Wednesday's triple-header: Tesla Q2 AH, Alphabet Q2 AH, and IBM's formal Q2 call all drop after the July 22 bell.

Macro:
• Trump announced 50% tariffs on Canadian goods, 30-day notice; oil imports exempted — trade desks flagging this as credible
• US-Iran tensions escalate: airstrikes + Houthi Red Sea threats push Brent past $91/barrel (+2.3%), WTI ~$85
• Gold ~$4,074 (+1.6%), Silver +4.5% to five-week high; both benefiting from geopolitical safe-haven bid
• Bitcoin $66,380 (+1.7%)
• IPO watch — Anthropic investor roadshow meetings ongoing ($965B valuation, S-1 filed June 1, October listing possible); OpenAI (~$920B) weighing 2027 IPO delay after watching SpaceX's SPCX debut (June 12)
Tomorrow: Triple earnings threat — Tesla Q2 AH (480k record deliveries set; margin compression is the real question), Alphabet Q2 AH (AI capex-vs-monetization crossfire; 21% revenue growth expected), IBM formal Q2 call (post-July-14 shock warning; down 28% YTD). Also watching Canadian tariff fallout, crude trajectory on Iran news, and any Fed speaker color.
