SEOUL — Shares of South Korean chipmaker SK Hynix closed down more than 15% on Monday, July 13, 2026, following its successful debut on the Nasdaq stock exchange at the end of last week. This decline comes just days after the company's shares rose approximately 13% on their first trading day in New York. The drop reflects growing concerns among investors that the memory chip industry's recent uptrend might have peaked. The KOSPI index also experienced a downturn amid these worries about the sector's outlook.
