South Korean chip giants plunge as AI data‑center regulation fears spark massive foreign sell‑off
On Nov. 6, Samsung Electronics and SK Hynix shares fell 16.13% and 20.17% respectively, driving the KOSPI down 8.78% to 4,911.28 and triggering a Level‑1 circuit breaker. The sell‑off was fueled by foreign investors net‑selling about 7.6 trillion won in the two stocks over the week, pushing foreign ownership to 45.95% for Samsung (its lowest in 17 years) and 48.27% for SK Hynix (its lowest in five years). Analysts linked the rout to concerns that U.S. mid‑term election outcomes could tighten regulation of AI data‑center construction, reducing memory‑chip demand.
Why it matters
The foreign‑investor outflow and steep price drops lowered the KOSPI index and heightened volatility, as the two stocks together account for roughly 42% of KOSPI market capitalisation (the company’s note says). The ownership lows also signal reduced foreign support for South Korea’s semiconductor sector, which could constrain future price recovery.
