SEOULShares of South Korean chipmaker SK Hynix closed down more than 15% on Monday, July 13th, 2026, following its successful debut on the Nasdaq stock exchange at the end of last week. This decline came just days after the company's shares rose about 13% on their first trading day in New York.

The drop in SK Hynix shares coincided with a broader tumble in the KOSPI index, driven by concerns that the memory chip industry's recent uptrend might have reached its peak. Market participants are showing increased caution amid uncertainty about the sector's future growth prospects.

The developments highlight volatility in the semiconductor market shortly after SK Hynix's entry into the Nasdaq, underscoring investor apprehension despite the initial positive reception.
