The Nasdaq Composite (NASDAQINDEX:^IXIC) fell 1.40% to 25,520, the S&P 500 (SNPINDEX:^GSPC) lost 1.02% to 7,457, and the Dow Jones Industrial Average (DJINDICES:^DJI) slipped 0.77% to 52,146, extending a tech-led sell-off as a worsening semiconductor rout outweighed strong insurance sector earnings.
