The Rebound Finally Gained Breadth
The local repair from the prior session began to spread across markets on July 9. QQQ rose 1.7%, SMH 2.5%, AMD 6.9%, and Micron 4.5%. Nvidia fell 0.7%, but SPY still gained 0.9%, while VIX dropped 6.3% to around 15.8 (sources: Yahoo Finance and Cboe, July 9, 2026 close).
European semiconductors moved even more uniformly. ASML rose 4.8%, ASM International 4.2%, BESI 5.6%, Infineon 4.3%, and STMicroelectronics 7.2% (sources: Euronext and Deutsche Börse, July 9 close). Equipment and chip companies that had fallen together on July 7 now rebounded together two sessions later.
A-shares amplified that breadth. CSI 300 rose 2.5%, CSI 500 3.1%, and CSI 1000 2.2%. Naura Technology, Dongshan Precision, Yoke Technology, and GigaDevice each gained roughly 10%, while HGTECH rose 7.8% and Shengyi Technology 8.2% (sources: China Securities Index Co., Shanghai Stock Exchange, and Shenzhen Stock Exchange, July 9 close). This was no longer an isolated pulse in one or two memory names. Equipment, materials, PCBs, and memory all participated.
TSMC Left a Gap
Taiwan did not fully confirm the expansion. TSMC fell 2.0% and Global Unichip 1.4%, while Alchip rose 3.6%, Unimicron 1.4%, and Nan Ya PCB 10.0% (source: TWSE, July 9 close). High-beta segments bounced, but the central manufacturing anchor weakened.
Korea followed only modestly. KOSPI rose 0.6%, SK hynix 5.3%, and Samsung Electronics just 0.2% (source: KRX, July 9 close). Memory repaired, but the index and its largest name did not provide equally strong confirmation.
The Other Side
The constructive reading is that the U.S., Europe, and A-shares strengthened together while VIX declined. The rebound had spread from individual names into multiple markets and layers of the supply chain. The cautious reading is that TSMC and Samsung Electronics did not confirm with similar strength. Better high-beta breadth is not the same as a re-rating of the demand anchors.
July 9 was better because participation widened, not simply because prices rose more. The counter-signal was equally clear: if TSMC and Samsung continue to lag, the move remains an elasticity repair rather than a fully synchronized AI chain.
