US semiconductor stocks face worst week since ‘liberation day’ rout
Financial Times reports the index is on track for its poorest weekly performance in over a year, as investor sentiment shifts against artificial intelligence investments.

US semiconductor stocks are on track for their worst weekly performance since last year’s market downturn, colloquially known as the ‘liberation day’ rout, according to a report by the Financial Times. The decline marks a significant reversal in the ‘AI trade’, reflecting a broader shift in investor sentiment regarding artificial intelligence investments.
The downturn comes against a backdrop of heightened geopolitical activity, including a recent summit in Beijing attended by US President Donald Trump, Chinese President Xi Jinping, and major US technology executives such as Elon Musk, Tim Cook, and Jensen Huang. Discussions at the summit centred on trade, artificial intelligence governance, and regional security, including the Strait of Hormuz.
While the immediate drop in the semiconductor index is linked to changing market confidence in AI, the sector has seen mixed signals recently. Nvidia shares had previously surged by more than 2% following the approval of a chip sale, while Cisco is undertaking restructuring efforts that include job cuts. These events highlight the volatility within the broader technology landscape.
Chinese President Xi Jinping used the summit to urge multilateral AI governance and collaboration with BRICS nations and other developing regions. This push for international cooperation in AI capacity-building occurs amidst intensifying global trade tensions and discussions on how to manage the technology’s global access.
The current market movement represents the first time since the ‘liberation day’ rout last year that the semiconductor index has faced such a severe weekly challenge. The convergence of geopolitical summits and shifting investment narratives continues to weigh on the sector, with the full magnitude of the weekly decline yet to be finalised.
