Weekly Wrap: Is AI Mean Reversion Taking Shape?

U.S. stocks traded through a notable rotation during the week, as weakness in AI and mega-cap technology names contrasted with improving performance beneath the surface.
The Nasdaq-100 (NDX) is down nearly 1% this week as of Thursday's close, while the Dow Jones Industrial Average ($DJI), Dow Transports ($DJT) and Russell 2000 (RUT) moved higher. WTI crude remained near the psychologically important $100 level as Middle East tensions continued to preserve an energy-risk premium. The S&P 500 (SPX) also pulled back but remains relatively close to record territory. The divergence could suggest the market is becoming more balanced rather than entering a broad risk-off phase.
Sector performance supported that message. Consumer staples, utilities, healthcare, and financials were the strongest groups over the past week through Thursday, while communication services and technology were the weakest. Staples benefited from defensive positioning, while utilities gained as Treasury yields retreated. Financials also performed well as investors rotated toward value and away from AI trades. Communication services and technology lagged as semiconductor stocks and other high-multiple growth names came under pressure.
Market Breadth Expands
Even during Thursday’s heavy selling in technology, the majority of U.S. stocks advanced. The equal-weighted portions of the market held up considerably better than the capitalization-weighted indexes, suggesting investors could be recycling capital rather than abandoning equities altogether. Apple (AAPL), meanwhile, traded near lifetime highs during the week, standing out from the broader weakness in AI-heavy mega-cap technology. See The Big 3: NVDA, AAPL, MSFT | Trading 360
The Bond Market Adds to the Rotation
After last month’s panic over higher rates, the 10-year Treasury yield moved back below 5% as investors returned to longer-duration government bonds. Earlier this year, enormous demand for capital tied to government borrowing and the AI infrastructure buildout helped pressure Treasuries as investors crowded into equities. This week, some of those flows reversed as money moved out of high-flying AI names and back toward bonds. Importantly, the VIX remained below 20 despite the apparent technology selloff, suggesting the market has not shifted into a pronounced hedging or panic regime.

A Big Week for Tech Earnings
Earnings also illustrated the widening gap between strong underlying AI demand and increasingly demanding investor expectations. Meta Platforms (META) reported strong revenue growth, but investors focused on negative free cash flow and aggressive AI infrastructure spending. Tesla (TSLA) generated positive free cash flow but reduced its annual capital-spending outlook, raising questions about the pace of future investment in autonomy, robotics, and AI.
Lam Research (LRCX), a global supplier of wafer-fabrication equipment and services, fell sharply after its quarterly earnings report despite otherwise solid demand tied to advanced semiconductor and memory production. The stock dropped 11% Thursday after management flagged near-term supply constraints and projected a decline in China’s revenue contribution in the coming quarter.

Overall, the week looked less like a broad market breakdown and more like a normalization of leadership. Improving breadth, lower Treasury yields and subdued volatility suggest the broader market can still be resilient even as its most crowded technology trades undergo a significant reset.
