US stock market today: S&P 500, Nasdaq futures edge higher as tech stocks rebound; Brent crude slips below $75

US stock futures edged higher on Wednesday, with S&P 500 futures up 0.2% and Nasdaq 100 futures climbing 0.5%, as tech stocks attempted a rebound after a two-day sell-off in semiconductors that wiped billions in market value. The Nasdaq 100 has fallen 3.3% and the S&P 500 declined 1.4% over the past two sessions on concerns over whether massive AI-related capex by hyperscalers will deliver adequate returns. Meanwhile, Brent crude fell 3.11% to $74.63 a barrel, down 18% so far this month, supported by easing US-Iran tensions, and the dollar index hovered around 101.4.
