SK Hynix Shares Tumble Over 15% in Seoul After Record Nasdaq ADR Debut

South Korea’s second-largest chipmaker posted its biggest one-day percentage decline on record in domestic trading Monday after its American depositary receipts surged 13% in their first day on the Nasdaq, the largest U.S. listing by a foreign company. SK Hynix raised $26.5 billion through the sale of 17.79 million new ADRs priced at $149 each, with 10 ADRs representing one common share. The ADRs, initially trading under ticker SKHYV, closed Friday at $168.01 and transitioned to SKHY. The offering was more than seven times oversubscribed, drawing strong U.S. demand for exposure to the company’s high-bandwidth memory leadership in artificial intelligence applications. The Seoul-listed shares fell more than 15% on Monday, erasing earlier gains tied to the U.S. listing and reflecting profit-taking after a sharp run-up in 2026. The stock had climbed about 260% year-to-date entering the week. Trading volumes spiked as investors adjusted positions following the landmark cross-listing.
