US semiconductor stocks experienced continued selling pressure in Wednesday's pre-market trading session, with major memory companies posting declines despite a broader technology rebound. According to latest reports, Micron Technology shares fell around 0.8%, while SanDisk declined 1% and SK Hynix slipped 0.9% in pre-market trading. The weakness comes despite South Korea's KOSPI gaining 0.97% during Wednesday's session, highlighting the specific concerns affecting memory stocks rather than broader market sentiment.
The primary driver behind Wednesday's decline is rising competition in the NAND market, particularly from China's Yangtze Memory Technologies (YMTC). As reported by multiple sources, YMTC aims to become the largest NAND producer by 2027, raising significant concerns about supply and pricing dynamics in the memory market. This competitive threat is weighing heavily on memory stock valuations, even as the broader technology sector shows resilience. The potential for increased supply from YMTC could pressure current pricing and market share for established players like Micron, SanDisk, and SK Hynix.
The immediate trigger for Monday's weakness came from Samsung Electronics, which experienced significant pressure after its record shareholder-return plan failed to meet investor expectations. According to reports from Essential Business Intelligence, Samsung expects to return between 90 trillion won and 110 trillion won to shareholders in 2026. However, investors had been looking for clearer commitments on immediate share buybacks and share cancellations, leading to disappointment that triggered the broader sell-off in semiconductor stocks, particularly memory companies that have benefited substantially from the artificial intelligence boom.
Investors are also awaiting Nvidia's fiscal second-quarter results for fresh signals on artificial intelligence demand and memory spending. As noted by multiple reports, these earnings will provide crucial insights into the strength of AI-related demand and corporate spending on data-centre infrastructure. The market is particularly watching Nvidia's revenue outlook, AI accelerator demand and commentary on data-centre spending for potential stabilization of the broader semiconductor trade. The upcoming results are expected to provide important signals on whether the current weakness in memory stocks reflects temporary positioning concerns or fundamental shifts in AI-driven demand patterns.
