Wall Street selloff deepens after Trump’s tariff escalation on China

U.S. stocks tumbled as former President Trump announced a sweeping 100% tariff on Chinese imports starting November 1, escalating trade tensions. Tech giants including Nvidia, Tesla, and Amazon each fell more than 2%, while semiconductor stocks slid 6.3%, marking the sector’s steepest drop since April. The S&P 500 and Nasdaq posted their worst single-day declines in months as investors fled risk assets amid renewed uncertainty about global supply chains and inflation pressures. (Reuters)
