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.
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.
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.
