Samsung, SK Hynix shares slide 7%+ on Nasdaq opening jitters as chipmakers bear brunt of tech selloff
Samsung Electronics fell 7% and SK Hynix dropped 9% in early Thursday trading after a broader U.S. semiconductor selloff spilled into Asian markets overnight. Their South Korean peer SK Square, the largest shareholder of SK Hynix, sank over 10%. The decline wiped billions in market value as investors dumped chip stocks, with Micron diving 10% on Wall Street despite a 260% year-to-date gain; Broadcom and Nvidia each fell 1-2%.
SK Hynix is days away from its Nasdaq listing on July 10 via American Depositary Receipts under ticker SKHY, a $29.4 billion offering that would be the largest ADR flotation on record, surpassing Alibaba's $21.8 billion debut in 2014. The company holds about 60% of the global HBM (high-bandwidth memory) market and has been a primary beneficiary of AI infrastructure buildout, with Q1 2026 revenue up 60% quarter-on-quarter and operating margins reaching 72%.
The selloff reflects profit-taking and investor concerns about valuation consolidation as memory chipmakers face headwinds: HBM contract prices face downward pressure in 2026, Samsung is closing its gap in HBM4 production, and any slowdown in AI capex would directly impact memory demand. SK Hynix and Samsung trades at forward P/E multiples of 8-9x compared to 20+ for most mega-cap tech peers, signaling unfinished revaluation work for US-listed memory suppliers.
