🔔 AI Stocks Close — Tuesday, June 23, 2026 at 4:00 PM

Closes: SPX 7,365.46 (-1.44%) · NDX ~-2.2% (Nasdaq Composite 25,587.04, -2.21%) · DJI 51,665.49 (-0.09%)
Day narrative: A risk-off, chip-led rout — memory and semis got hammered as Asia melted down overnight and traders priced in a more hawkish Fed, while money rotated into software, mega-cap tech ex-chips, and defensives. The Dow held flat; the Nasdaq took the damage.

Sectors: Best Consumer Staples (+1.8%) · Worst Semiconductors (PHLX/SOX -7.9%, tech sector -3.7%)

Movers:
• MU -10.25% — memory highflier crushed ahead of tomorrow's earnings; SK Hynix/Samsung tumbled 12%+ overnight
• ARM -8.41% — caught in the global semi unwind
• AMD ~-6% to -9% — part of the chip-equipment/AI-spend reckoning
• NVDA -4.1% — day two of the slide as AI-capex sustainability worries deepened
• SanDisk/Marvell ~-8% to -11% — memory and networking names swept up
• WMT/JNJ +2% — defensives bid as rotation hit

After-hours / Earnings:
• Quiet after-hours — no major watchlist earnings tonight. The marquee event is teed up for tomorrow (MU). SMH closed down 6.5% at $625.62.

Watchlist:
• MU $1,102.66 (-10.25% day)
• NVDA $202.51 (-4.1% day)
• ARM (-8.41% day)
• AMD (~-6% to -9% day)
• AVGO ~$393 (lower with the group)
• MSFT (higher — rotation winner)
• AMZN (firm — rotation winner)
• GOOGL (-1% day)
• META (mixed, outperformed chips)
• AAPL (relative outperformer)
• TSLA (modestly lower)
• PLTR (volatile, off recent highs)
• SMCI (lower with semis)
• ORCL (held up better than chips)
• TSM (lower with the global chip rout)
• ASML (lower — chip-equipment pressure)
• SOUN / IONQ / BBAI (small-cap AI, lower with risk-off tape)
• CRM / ADBE / SNOW / MDB / NET / CRWD (software relatively firmer as rotation favored software)
• IBM (resilient)
(Note: only the bolded SPX/Dow levels and the chip movers above are verified closing figures; several mega-cap and software names lacked a confirmable exact close, so directional reads are given rather than fabricated prices.)
Watch item — not yet public: No fresh Anthropic or OpenAI IPO/funding headlines crossed today.

Macro: Hawkish Fed repricing the day's theme — nine of 18 policymakers now see at least one more hike this year; traders increasingly betting on a second hike by December. South Korea's KOSPI cratered 9.99% (steepest in 3+ months), triggering an exchange trading halt; BofA rate-hike note added fuel.
Tomorrow: Micron (MU) reports fiscal Q3 after Wednesday's close — Street near $19.72–$20.57 EPS on ~$34.5–35B revenue, with the 81% gross-margin guide and HBM4 allocations the key tells; options imply a ~17% one-day move. PCE inflation gauge due Thursday.
