Shares of major semiconductor companies fall sharply as a broader chip-sector sell-off spreads to Wall Street. Reports describe steep declines in AI-linked semiconductor stocks, with multiple companies in the segment dropping as much as around 12% at points during the session. The move weighs on major U.S. indexes, including the Nasdaq, which falls more than 2% amid the technology-led downturn. The articles attribute the pressure to a deepening global rout in semiconductor equities, where investor sentiment turns risk-off and selling accelerates across the sector. The sell-off includes both memory and chip-related names, with investors reacting to weakness that affects the wider semiconductor complex rather than a single company. Overall, the coverage characterizes the market move as part of a continuing decline in chip stocks and related technology exposure, resulting in lower trading levels for large-cap semiconductor companies and a broader drag on Wall Street benchmarks.
