- SK Hynix shares declined over 8% in Seoul, while SKHY tumbled 9% on the Nasdaq exchange
- Samsung experienced a decline exceeding 7% as semiconductor stocks faced widespread selling pressure
- The KOSPI index in South Korea plummeted 6% to 6,460.6, temporarily activating circuit breakers

Shares of SK Hynix tumbled more than 8% during Wednesday’s trading session in Seoul, while its American depositary receipts listed as SKHY declined 9% on the Nasdaq. Samsung’s stock fell over 7% in parallel trading.
This decline occurred as part of an extensive rotation out of artificial intelligence-focused semiconductor equities. Micron Technology and Western Digital both experienced 7% losses, while SanDisk plummeted 9% during the previous trading session.
The South Korean KOSPI benchmark index tumbled 6% to reach 6,460.6, momentarily activating automatic circuit breakers that paused trading activity during the session.
Market headwinds originated from Tuesday’s U.S. trading, where equities declined alongside a spike in crude oil prices. Ongoing tensions between the United States and Iran continued escalating, driving energy costs upward.
Rising oil prices contributed to an increase in government bond yields. Elevated Treasury yields effectively raise discount rates for investors, complicating the valuation case for expensive growth-oriented equities.
Florian Ielpo from Lombard Odier Investment Managers explained the dynamic clearly: “The investment hurdle rate is rising again. This time through a combination of oil, fiscal supply and long-end term premium rather than a renewed acceleration in short-rate expectations.”
The Double-Edged Sword of AI Exposure
SK Hynix and Samsung have emerged as major winners from artificial intelligence-fueled demand for advanced high-bandwidth memory semiconductors. However, this concentrated exposure now makes them vulnerable when market participants shift away from AI-themed investments.
Market rotations in this sector tend to be swift and severe. Given their central positioning in the AI memory chip narrative, these companies face disproportionate selling pressure when sentiment shifts.
Company Unveils $29 Billion Stock Repurchase Program
In an independent corporate announcement released Wednesday, SK Hynix disclosed plans to repurchase and eliminate 40 trillion won in treasury shares, equivalent to approximately $28.61 billion.
The semiconductor manufacturer also pledged to distribute a minimum of 50% of its free cash flow produced during the 2025-2027 period back to its shareholders.
Additional specifics regarding the timing and execution methodology will be disclosed when the company reports its third-quarter financial results.
Notwithstanding Wednesday’s sharp decline, Wall Street equity analysts maintain a Strong Buy consensus rating on SKHY stock. The consensus price target stands at $245.50, suggesting potential appreciation of approximately 58% from present trading levels.
The iShares MSCI South Korea ETF declined 8.13% during Wednesday’s session, while the Roundhill Memory ETF, which includes SK Hynix as a major portfolio component, fell 8.76%.
