Chip stocks experienced a significant decline in premarket trading on Monday, with South Korean memory maker SK Hynix leading the way. Investors were seen taking profits amidst concerns of an overextended and crowded trade. Additionally, worries over a report indicating that SK Hynix’s operating profit for the current quarter may fall short of consensus estimates added to the negative sentiment.
SK Hynix’s stock plummeted by 15% in Asia, setting the stage for a sharp decline in US-traded shares following their strong debut on Friday. Other major players in the industry such as Samsung Electronics, Micron, Sandisk, and Western Digital also saw their stocks drop by more than 5% on Monday morning. Moreover, chip stocks like Intel, AMD, Broadcom, and Arm Holdings declined by approximately 2% alongside the broader sector.
This decline marked a stark reversal from SK Hynix’s successful US debut, where its American depositary shares surged 13% above the $149 offering price. The company managed to raise a staggering $26.5 billion in the offering, making it the largest US IPO ever by a foreign entity.
The semiconductor industry has been volatile in recent months, reaching its peak in late June amid concerns that hyperscale cloud providers might need to take on more debt to support the increasing demand for AI infrastructure. Any signs of a slowdown in AI investment could potentially trigger a widespread sell-off in memory stocks.
Semiconductor stocks have played a crucial role in driving earnings growth this year, bolstering the overall stock market as AI inference workloads require substantial amounts of memory and other components to handle complex queries and power AI agents.
