The stock market suffered a sharp technology-led retreat Friday, as investors rotated away from artificial intelligence shares and reassessed the cost of funding the industry’s rapid expansion. The Nasdaq Composite fell 2.2%, while the S&P 500 declined 1.2%. The Dow Jones Industrial Average proved more resilient, dropping 268 points, or 0.5%.
The declines put major indexes on track for a difficult week. The S&P 500 was down about 2% for the week, while the Nasdaq had fallen more than 4%, placing the technology-heavy index on pace for its worst weekly performance since June. By contrast, the Dow remained modestly higher for the period.
Stock Market Slide Intensifies as AI Trade Loses Momentum
Chipmakers were among the biggest pressure points. The VanEck Semiconductor ETF fell 1% Friday and was down roughly 8% for the week, its steepest weekly decline since July. Micron Technology, Advanced Micro Devices and Sandisk were among the companies weighing on the sector.
Investors have grown increasingly concerned about competition from China, the possibility of future chip oversupply and the enormous amount of capital being borrowed to build artificial intelligence infrastructure. Those worries have made formerly popular AI-linked shares particularly vulnerable to profit-taking.
CoreWeave, a major provider of cloud computing services for AI companies, dropped about 10% Friday. The decline pushed its weekly losses above 23%. The company’s total debt has risen beyond $51 billion, increasing concerns about refinancing costs if interest rates stay higher for longer.
“The question is: Is this a systemic issue?” said Michael Rosen, chief investment officer at Angeles. He acknowledged that rising debt issuance deserves close attention, while adding that the broader market is not yet near levels of excessive leverage.
Powerful Rotation Favors Energy and Defensive Shares
The sell-off was not evenly distributed across the entire stock market. Communication services and information technology led the S&P 500 lower, falling 2.7% and 2.4%, respectively. Consumer discretionary shares also declined 1.5%.
Energy stocks moved in the opposite direction. Five of the 11 S&P 500 sectors were higher, led by energy with a 2.1% gain and utilities with a 1.2% advance. Chevron helped limit the Dow’s losses as crude prices surged.
West Texas Intermediate crude futures climbed nearly 3% to $100.78 a barrel, while Brent crude rose about 3.3% to $109.37. The move came amid escalating tensions involving Iran and the Strait of Hormuz, as well as continued attacks connected to the Russia-Ukraine conflict.
Inflation and Fed Policy Add Critical Uncertainty
Higher energy prices are adding to inflation concerns at a difficult moment for policymakers. Wholesale inflation recorded its largest increase since 2022 this week, while consumer prices remained well above the Federal Reserve’s 2% target.
Federal Reserve Chairman Kevin Warsh spoke at an International Monetary Fund event in Bangkok but did not signal whether officials would raise interest rates before the end of the year. Traders interpreted his remarks as a sign that policymakers may leave rates unchanged at the October 27–28 meeting.
According to the CME Group’s FedWatch tool, markets were pricing in an 85% probability that the central bank would maintain its overnight interest rate. Treasury yields edged lower Friday, although Wells Fargo Investment Institute warned investors against rushing into longer-duration bonds.
“Currently, we do not believe we have reached the peak in interest rates for this cycle, so caution is warranted,” said Darrell Cronk, president of Wells Fargo Investment Institute and chief investment officer of Wealth & Investment Management.
Investors Search for Safer Opportunities
Some investors are looking beyond semiconductor leaders for value. Workday gained more than 2% during the broader technology sell-off after recovering from a steep first-quarter decline. Manish Gupta of First Eagle Investments said the software company’s business had improved even as its valuation remained attractive compared with similar private-market companies.
Other individual stocks also made notable moves. Moog rose more than 4% after Morgan Stanley upgraded the shares and raised its price target. Fox Factory dropped 9% after its chief executive stepped down and the company reduced its full-year revenue outlook. Travelers fell 4% despite reporting earnings above analyst expectations.
Overseas markets reflected the same uncertainty. South Korea’s Kospi gained 2% Friday but still recorded a 14.5% weekly decline, its worst performance since 2008. Samsung Electronics and SK Hynix were hit particularly hard during the week as investors questioned the durability of the global AI investment cycle.
For now, traders are watching several forces at once: corporate debt, oil prices, inflation data, Federal Reserve guidance and the sustainability of AI-related valuations. The combination could keep volatility elevated across technology shares and the broader stock market in the sessions ahead.
