Semiconductor companies experienced a significant surge on Monday, with sector stocks notably outperforming the broader market following the announcement of new restrictions by the Biden administration on China's access to essential chip components and AI technology. The Philadelphia Stock Exchange Semiconductor Index climbed 2.9%, marking its largest one-day percentage increase in roughly a month, while the Nasdaq 100 Index saw a more modest gain of 1.1%.
Notable movements in the sector included Intel (NASDAQ:INTC), which jumped 5% after the company announced the departure of CEO Pat Gelsinger. Other semiconductor and AI-related companies also saw their shares rise, with Taiwan Semiconductor Manufacturing Co (NYSE:TSM) up by 5.2%, ARM by 5%, Advanced Micro Devices (NASDAQ:AMD) by 3.5%, and Nvidia (NASDAQ:NVDA) by 0.8%. Companies specializing in semiconductor capital equipment also gained, with Lam Research (NASDAQ:LRCX) increasing by 6%, Applied Materials (NASDAQ:AMAT) by 4.6%, KLA Corp (NASDAQ:KLAC) by 3.1%.
The new US measures are aimed at impeding China's ability to develop advanced semiconductors and AI systems that could enhance its military capabilities. The Department of Commerce has implemented additional curbs on the sale of high-bandwidth memory and chipmaking gear, including equipment produced by US firms in foreign countries. Additionally, 140 Chinese entities were added to a blacklist for allegedly acting on behalf of Beijing, though their names were not immediately disclosed.
The rules, which have been under consideration for some time, are intended to slow China's progress in the semiconductor field. They include restrictions on the sale of two dozen types of manufacturing equipment and three software tools. These controls apply to both US and foreign companies, utilizing the foreign direct product rule to regulate goods made abroad with US technology. However, there are exemptions for countries capable of imposing similar controls, creating a pathway for allies like Japan and the Netherlands to enact comparable measures.
Secretary of Commerce Gina Raimondo commented on the initiative, emphasizing the administration's strategy to address China's military modernization through export controls. The new regulations also target high-bandwidth memory chips, crucial for AI applications, adding to existing restrictions on advanced logic chips.
Analysts have been monitoring the situation, with Lynx Equity Strategies noting the potential for the sector to reach a pivotal moment. The release of the full details of the BIS export controls is expected to clarify the impact on individual companies within the semiconductor industry. The initial response to the new restrictions could influence market trends, with some companies potentially benefiting while others may face increased risks.
