U.S. Markets

  • TSMC's flawless print detonated the AI chain anyway: capex guidance raised to $60–64B spooked the sector, Nasdaq -1.5%
  • Memory's third leg down: Micron -5.7% below $1T cap, SanDisk -12.6%, WDC -9.2%; China's CXMT IPO prices for a 7/27 listing
  • Alphabet -4.4% on Bloomberg's Gemini 3.5 Pro delay scoop; the neocloud unwind sent Nebius -13.9%, -36% in a month
  • Trump's primetime address alleged China stole 220M voter files; day five of US-Iran strikes with a naval blockade on Iranian ports

Score6/10Stop executed Closed at $853, through the $880 stop — position closedThree-day slide ~-17%; market cap back below $1TFresh negatives CXMT's $8.55B IPO prices (lists 7/27) + the TSMC capex shockWSB mentions 841 — #1 for a third straight dayYTD gain (pre-pullback) +243%

Technicals — Closed at $853.20 through both the $880 stop and the 50-day ($930) on just 1.06x volume — day three came without a volume spike, which reads as orderly distribution, not a panic low. The 7-day RSI at 30.8 nears oversold; next support is the $800 round number and May shelf, with the 20-day far above at $1,033.

Fundamentals — The fundamentals didn't change — the other side of the trade did. HBM 2026 capacity is sold out with orders booked into 2027, but CXMT (the world's #4 DRAM maker at 7.7% share) just priced China's largest-ever semiconductor IPO at RMB 57.9B for a 7/27 listing — the China-capacity story graduated from rumor to prospectus. A single unverified report adds possible tighter US HBM export rules.

News — TSMC's capex raise to $60–64B triggered a sector-wide valuation scare with the SOX down ~4%. Morningstar warns AI names could give back 20–30% while BofA counter-raised SanDisk to a $2,500 target — the bull-bear split has never been this wide, and Buffett's 'everybody is gambling' line still tops the tape.

Neutral Sidelines

This long settles around -8% to -9% since the 7/2 baseline; the stop's value showed itself today — without $880 the conversation would be about -17%. Until CXMT lists and the HBM-export rumor resolves, memory is priced by sentiment, not earnings.

Entry Flat after the stop; a low-volume hammer at $800 with a 7-day-RSI divergence is the first reassessment point — no chasing below a reclaimed 50-day ($930)Stop —Target —

Neutral

HBM pricing power and pre-sold 2027 visibility remain best-in-class, and post-washout it stays a core watch — but CXMT's IPO-funded expansion forces a rethink of long-run non-HBM pricing assumptions.

  • CXMT's funded expansion eroding DRAM pricing
  • Direct hit if HBM export curbs materialize
  • Sustained volatility while the profit overhang clears

Score6/10Stop executed Closed at $500.94, through the $518 stop — position closedGap vs NVDA -6.8% rolling 5-day vs NVIDIA's +1.4% (same data source)Location Closed right on the 50-day ($496)Consensus target $539 (+7.6%)RSI(14) 46.9

Technicals — Closed at $500.94 through the $518 stop, parking exactly on the 50-day at $496 — the last near support; failure there opens the $460 gap-fill. Volume was flat at 1.04x, and the weekly scissors versus NVIDIA (+0.33%) widened to eight points.

Fundamentals — No company-specific negative — which is precisely the problem: under the TSMC capex shock the market re-ranked the AI chain by pricing power, and AMD's share-for-margin MI playbook with hyperscalers gets treated as pure beta in a risk-off. With consensus at $539, just 7.6% above, the crowding was already spent.

News — Down 5.3% in the TSMC-capex panic alongside memory's third leg (Intel -4.4%, Marvell -8.7%, extending losses on capex fears a day after Erste's valuation downgrade). Its next self-defense comes at early-August earnings — until then, the signal ledger owes it no direction.

This long settles near -9% since the 7/7 entry. Relative strength drove the exit: within a sector you hold only the strongest, and right now that isn't AMD.

Entry Flat and watching: a low-volume hold at the 50-day ($496) plus a narrowing NVIDIA scissors is the reassessment trigger; a break targets the $460 gapStop —Target —

Neutral

The MI roadmap and server-CPU share story are intact and the valuation reasonable; reassess after the AI unwind passes and August earnings confirm data-center guidance.

  • MI margins capped by hyperscaler bargaining
  • NVIDIA's deepening lock-in squeezing the niche
  • If AI capex truly slows, second-source suppliers bleed first
