QQQ falls 2.05% and trails SPY amid inflation, Iran and AI investment headlines

QQQ opened 0.89% lower and finished down 2.05%, while SPY opened 0.73% lower and finished down 1.36%. QQQ trailed SPY by 0.68 percentage points. Both weakened through regular trading, reached their lows shortly after the close and recovered part of the decline after hours. Jobless claims were close to estimates, while Federal Reserve commentary kept inflation risk in view. Iran-related diplomacy and military reports remained prominent, and Meta outlined a $10 billion AI data center investment.
