Foreign investors have offloaded a net 5.33 trillion won (approximately $3.5 billion) of SK Hynix shares over the past week, extending a broader 12-day selling streak. The massive institutional sell-off represents a profit-taking wave following a historic KOSPI rally driven by the artificial intelligence boom. Meanwhile, financial regulators have clamped down on promotional events ahead of the May 27 listing of Korea's first 2x single-stock leveraged ETFs tracking SK Hynix, warning of severe volatility risks. Despite the heavy institutional selling, SK Hynix's stock remained stable, closing at 1,941,000 won.
