Oracle’s cloud margin miss pulls S&P 500 off winning streak

Oracle shares slid nearly 5% after the company reported weaker-than-expected cloud margins, breaking the S&P 500’s eight-day rally. The results triggered broader weakness in the tech sector, as investors reassessed profitability within cloud and AI-linked businesses. Rising semiconductor input costs and concerns over inflated AI valuations added pressure to market sentiment. The pullback reflects growing investor caution toward earnings resilience in a maturing technology cycle across U.S. markets.
