US markets decline as a broad sell-off in technology stocks triggers renewed volatility and heightens concerns that valuations tied to artificial intelligence expectations may be overstretched. Multiple outlets describe the move as a “wake-up call” for Wall Street following a prolonged run-up in riskier assets. The drop spreads beyond US tech, with reports noting that global stocks are also pulled lower.
In the US, the S&P 500 falls about 1.4%, and market commentary highlights that the index is coming off a streak of gains—11 weekly advances in the last 12—driven largely by technology. The Nasdaq and other technology-heavy segments are reported to be under pressure alongside major US tech firms, contributing to a sharper risk-off shift. The sell-off is attributed in part to worries about “frothy” valuations, suggesting investors are reassessing how much of the recent rally can be justified by current expectations for AI-related growth. Overall, the coverage frames the move as a new bout of uncertainty after a nearly three-month period in which equities and related risk indicators rose.
