S&P 500: Equities under pressure from AI and energy shocks – Deutsche Bank

A 1.21% decline hit the S&P 500. Deutsche Bank’s Early Morning Reid reports a broad retreat from risk in US equities, with the index and NASDAQ suffering their steepest falls in months. AI-related shares and higher oil prices weighed on sentiment. Sharp losses in semiconductor and AI-exposed stocks contrasted with gains in defensive sectors. As US yields fell, a rise in the equal-weighted S&P 500 underscored rotation out of mega-cap growth stocks.

US stocks retreat as AI concerns return

"As all that was happening, yesterday also brought a fresh wave of concern around AI-driven growth, reversing some of the optimism from earlier in the week. So it was a rough session for several of the most affected names, and the Philly semiconductor index (-6.72%) had its worst day since June, whilst CoreWeave’s share price (-10.06%) fell to its lowest since May 2025."

"Put together, this all helped drive the broader indices lower, with the S&P 500 (-1.21%) posting its worst daily performance since July, whilst the NASDAQ (-2.60%) had its biggest decline since June."

"However, note that the main defensive sectors rallied strongly, with consumer staples (+3.11%) and utilities (+1.98%) leading the way as two thirds of S&P 500 constituents moved higher, helped by the fall in yields."

"This also marked the biggest outperformance of the equal-weighted S&P 500 (+0.77%) over the market cap index since July 2024."
