- SK Hynix — Cratering — Semiconductor sector selloff, foreign profit-taking
- LG Electronics — Down 10%+ — Jensen Huang hype priced in; now reversing as global tech names correct
Overseas Market Linkage Points
U.S. Semiconductor Giants Tank—NVIDIA and Broadcom Lead the Way
The American chip firms that ignited the global AI boom are now in full correction, erasing ~2 trillion won in market cap in a single day. Domestic memory chip leaders follow suit, driving the KOSPI more than 5% lower.
Strong U.S. Jobs Data → Dollar Strength → Won Weakness Worsens
The Labor Department's robust employment figures lifted the dollar modestly, underpinning the won-dollar breach toward 1,550—compounded by risk-off sentiment tied to global inflation concerns.
