S&P 500 Futures Trade Flat as Global Tech Selloff and Costly Oil Weigh

S&P 500 futures traded flat Tuesday while Dow futures rose 0.2% and Nasdaq futures slipped 0.3%, as renewed skepticism over artificial intelligence investments halted a recent technology rally. Global markets retreated following elevated crude oil prices exceeding $110 a barrel and heavy losses across regional chipmakers. South Korea's Kospi dropped 3.7% to its lowest level since April 7, while major European chip shares, including Technoprobe and Siltronic, declined over 4%. Broader European equity indices also slumped more than 1% amid rising bond yields and political unrest in France.
