July 7, 2026, 12:29 AM EDT. SK Hynix slid 6.7% in Asian trading July 7, days before its U.S. listing on July 10. The stock, which had jumped after the June 30 IPO announcement, has dropped from 2.749 million Korean won to 2.05 million-a 25% plunge-on concerns about macroeconomic headwinds, possible IPO dilution, and short-lived sentiment. Investors grew cautious as tech giants put money into AI data centers with few clear payoffs now, while big planned spending from Samsung and SK Hynix and talk of oversupply weighed. SK Hynix cut the reference IPO price, adding to the pressure. The company is set for inclusion in the Philadelphia Semiconductor Index, which could draw passive fund buyers and help the stock, but some see more downside if those inflows don't come through.
