Korea Took Back Part of the Break
U.S. markets were closed on July 3 for the observed Independence Day holiday, leaving Asia and Europe to set the tone for the global technology chain. Korea produced the strongest answer: KOSPI rose 5.8%, SK hynix 10.9%, and Samsung Electronics 8.2%. One session earlier, they had fallen 7.9%, 14.6%, and 9.1%, respectively (sources: KRX and Yahoo Finance Korea, July 2-3, 2026 closes).
That is a large rebound, but not yet a trend reversal. SK hynix remained below its July 1 close across the two sessions, and KOSPI recovered only part of the previous day’s damage. The tighter description is that Korea delivered the strongest mean reversion after the sharpest liquidation.
European semiconductors confirmed the direction. ASML rose 3.6%, ASM International 4.1%, and BESI 4.2%. Nikkei 225 gained 1.5%, but Tokyo Electron advanced only 0.4% (sources: Euronext, Deutsche Börse, JPX, and Yahoo Finance Europe / Japan, July 3 close). Repair spread into European equipment, while Japan’s equipment response remained restrained.
Taiwan Did Not Turn With It
Taiwan stayed split. TSMC fell 0.8%, Global Unichip 5.4%, and Alchip 5.0%, while Nan Ya PCB gained 3.5% (source: TWSE, July 3 close). Korean memory and European equipment bounced, but Taiwan’s high-beta design-service names continued to unwind. This was not a clean global semiconductor recovery.
A-shares were also subdued: CSI 300 and CSI 500 each rose about 0.6%, while CSI 1000 was roughly flat (source: China Securities Index Co., July 3 close). The overseas rebound did not translate directly into a domestic growth rally.
The Other Side
The constructive reading is that Korea’s two memory leaders surged and European equipment joined in, making July 2 look like an overshoot. The cautious reading is that the world’s most important price-setting market was closed, while Taiwan’s high-beta names remained weak. Cross-market confirmation was still missing.
The useful signal from July 3 was not that semiconductors were “back,” but the order of repair: Korea first, Europe next, Japan modestly, Taiwan still divided, and A-shares unmoved. The next U.S. session would test whether local mean reversion could become a shared global direction.
