By 04:00 ET, QQQ was down 1.88% and SPY 0.73% after both opened lower, leaving SPY ahead by 1.15 percentage points. The U.S. 10-year Treasury yield reached its highest since early 2025, July housing starts and pending home sales missed estimates, and Trump said no talks with Iran were scheduled. Overnight, Trump paused planned 50% tariffs on Canada for three days and the Financial Times reported that China eased limits on Nvidia H200 chips.
