SOXX fell about 5% over the past week, its worst weekly performance in a month, reflecting mounting pressure on chipmakers amid questions about the sustainability of AI infrastructure spending. DRAM declined 7.4% in the week, its worst run in nearly three months.
Micron faced pressure on Monday after Chinese chipmaker ChangXin Memory Technologies (CXMT) announced progress in advanced DRAM technology.
The development has raised concerns about growing competition in a market dominated by established players such as Micron, SK Hynix and Samsung Electronics.
The move comes as U.S. semiconductor stocks face renewed pressure following a strong rally this year, with investors booking profits and reassessing the sustainability of AI infrastructure spending.
Last week, chip stocks tumbled after reports said OpenAI's annualized revenue was around $50 billion at the end of September, below the $68 billion to $70 billion figures previously circulated in the market.
The discrepancy raised concerns about whether the AI startup's revenue growth could justify the enormous investments in AI infrastructure, including data centers and advanced processors.
Nvidia, AMD, Broadcom and Micron were among the chipmakers caught in the selloff.
On Stocktwits, the retail sentiment was 'bullish' for MU and DRAM, 'bearish' for NVDA, SOXX and 'neutral' for AMD as of early Monday.
With semiconductor stocks facing pressure from multiple directions, investors will be watching for signs of stabilization as the third-quarter earnings season gathers pace. Results from ASML and Taiwan Semiconductor Manufacturing Co. (TSMC) this week would be catalysts for the broader sector.
