FX.co ★ US Futures Hold Mixed Momentum

US equity index futures were mixed on Tuesday, as renewed volatility in chipmakers contrasted with continued strength in more traditional sectors. S&P 500 futures edged lower, while Dow contracts rose by 150 points to a fresh record. In contrast, the Nasdaq 100 was dragged 1.5% lower by a sharp selloff in semiconductor stocks. Micron and SanDisk fell 6% in premarket trading, even as Samsung reported a 19-fold jump in quarterly profit. That surge largely reflected this year’s powerful sector-wide rally, and investors are increasingly questioning whether AI hyperscalers can sustain such elevated capital spending on infrastructure. In a similar vein, SpaceX slipped 1% ahead of its planned inclusion in the Nasdaq 100. By contrast, banks and pharmaceutical companies mostly advanced, extending their strong run despite persistent macroeconomic uncertainty. Treasury yields ticked higher after an attack on an LNG tanker in the Middle East dampened expectations for a further easing in energy-related inflation pressures.
