SK Hynix shares sank 5.4% to ₩1,746,000 on Tuesday, prolonging a steep two-day drop that followed the company’s high-profile Nasdaq ADR debut on July 10. The decline took place amid volatile intraday trading: the stock rallied almost 5% earlier in the session before quickly reversing course.
Two principal factors are driving the selloff.
Analyst downgrades and a dimmer Q2 outlook. Several brokerages - Korea Investment Securities, Mirae Asset Securities, and Hyundai Motor Securities - trimmed their operating profit forecasts for SK Hynix’s second quarter. Each cited the same headwinds: average selling prices for high-bandwidth memory are coming in lower than analysts had expected, and DRAM bit growth has softened. Collectively, those trends increase the risk that the quarter will miss consensus expectations.
Valuation tension created by the ADR listing. The company’s Nasdaq ADR debut, which raised $26.5 billion, has produced a pronounced valuation gap between the U.S.-listed ADR and the Seoul-listed shares. That difference in valuation - now more than 20% according to market commentary - has encouraged domestic investors to sell the local listing and rotate into the ADR. The record-setting U.S. listing has effectively created a new benchmark against which the Korean stock is being measured, adding structural selling pressure to the domestic share.
Macro and market conditions have provided little offset to these company-specific dynamics. The KOSPI opened lower, remaining under pressure after an unusually turbulent session in which a circuit breaker was triggered - the seventh such halt this year - when the index plunged nearly 9%. Geopolitical developments also heightened risk perceptions: reports of U.S. military strikes on Iran and Iran’s announcement of a closure of the Strait of Hormuz unsettled Korean markets over the weekend.
International equity moves reinforced negative sentiment. Overnight in the U.S., the Nasdaq fell 1.6% and the S&P 500 declined 0.8%, contributing additional downward pressure on global semiconductor names.
Market data referenced in-session:
- US500: down 0.79%
- IXIC (Nasdaq): down 1.55%
- KS11 (KOSPI): down 1.95%
- 000660 (SK Hynix Seoul listing): down 6.07%
- SKHY (SK Hynix ADR): down 9.32%
Overall, the decline in Seoul-listed SK Hynix shares reflects a mix of near-term operational concern tied to memory pricing and bit growth, structural valuation shifts following a landmark ADR deal, and an unsettled broader market backdrop influenced by geopolitical events.
