Nasdaq-100 futures dropped over 1.5% to near 28,120, marking a third consecutive lower session and hitting their lowest level since July. The selling pressure is largely driven by concerns over artificial intelligence spending and cautious future earnings guidance from major tech companies, prompting market participants to question tech valuations. Meanwhile, the broader market showed dispersion as E-mini Dow futures posted gains amidst a sector rotation, while E-mini S&P 500 futures fell 0.5%.
