SK Hynix shares plunge was the market story in Seoul on Tuesday, with the South Korean chipmaker dropping more than 10%, according to CNBC. The move matters for retail investors because it shows how quickly pressure in U.S. semiconductor stocks can spill into Asian companies tied to artificial intelligence spending.
Samsung Electronics, another major South Korean chip name, fell more than 8%, CNBC reported. The selling also hit several AI-linked companies in South Korea: Samsung SDI dropped more than 7%, LG Innotek slid nearly 14%, Seoul Semiconductor lost about 6% and LG Chem declined more than 4%.
The pressure was not limited to Korea. In Japan, CNBC reported that Tokyo Electron fell more than 9% and Advantest dropped more than 8%. SoftBank Group, often treated by investors as an AI-linked name because of its stake in Arm, fell nearly 5%. Kioxia, a Japanese computer memory maker, sank more than 15%.
Why did SK Hynix shares plunge?
CNBC linked the drop to continuing weakness across semiconductor stocks after a down session on Wall Street. The VanEck Semiconductor ETF, known by its ticker SMH, fell more than 2% on Monday after losses on Friday, CNBC reported.
Several U.S. chip stocks also moved lower. AMD dropped 5%, Teradyne fell 4% and Micron Technology lost about 2%, according to CNBC.
For investors, the mechanism is straightforward: when U.S. chip stocks sell off, Asian suppliers and equipment makers can come under pressure because they sit in the same AI supply chain. Expectations for AI data-center spending have become a key driver of sentiment across both markets.
Samsung Electronics and SK Hynix are among the world’s biggest suppliers of high-bandwidth memory chips, CNBC reported. High-bandwidth memory, or HBM, is memory used in AI servers, where large amounts of data need to move quickly during AI computing tasks.
That makes both companies sensitive to changes in investor expectations for spending by U.S. hyperscalers. Hyperscalers are large technology and cloud-computing companies that build and operate large data centers, and their AI server budgets can influence demand for advanced chips.
What the chip selloff signals for investors
The Tuesday moves show how closely the AI trade has tied together companies across regions. A weaker session in U.S. semiconductors was followed by sharp declines in South Korean and Japanese names exposed to chips, memory, equipment and AI infrastructure.
The selloff does not, by itself, say whether demand for AI chips has changed. CNBC’s report pointed to market pressure and shifting expectations, rather than a company-specific announcement from SK Hynix or Samsung. For investors watching the sector, the key takeaway is that AI-linked stocks in Asia may react not only to local news, but also to moves in U.S. chip shares and broader sentiment toward AI spending.
