Stock index futures were mixed before the opening bell on Tuesday, with Nasdaq futures plunging as investors reassessed AI valuations. Dow Jones Industrial Average futures rose 0.11%, while S&P 500 futures slipped 0.22% and Nasdaq 100 futures fell 1.14%. The AI rally faced renewed scrutiny after Samsung Electronics' upbeat guidance prompted investors to revisit the lofty valuations that have fueled the recent surge in technology stocks. U.S. Treasury yields moved higher across the curve, with the benchmark 10-year yield rising about 3 basis points to 4.51% and the 2-year yield climbing nearly 4 basis points to 4.15%. Top premarket gainers included Fiserv, up 7.53%, while decliners included Sandisk, down 3.13%.
