The Nasdaq Composite suffered a sharp decline Friday as investors stepped away from artificial intelligence and semiconductor stocks, while rising oil prices and persistent inflation added to pressure on riskier assets. The tech-heavy index fell 2.14% to close at 26,140.03, ending the week more than 4% lower.
Friday’s retreat marked the Nasdaq Composite’s worst weekly performance since June. The index also finished below its 50-day moving average, a closely watched technical level that can signal weakening momentum. The S&P 500 declined 1.09% to 7,659.44, while the Dow Jones Industrial Average fell 175.28 points, or 0.34%, to 52,002.41.
Nasdaq Composite Sell-Off Accelerates as AI Stocks Slide
Technology shares led the market lower as investors questioned whether the huge spending required to build artificial intelligence infrastructure can generate sufficient returns. Concerns about increasing competition from China and a possible future oversupply of chips added to the selling pressure.
The VanEck Semiconductor ETF, known by its ticker SMH, dropped 3% Friday and lost approximately 10% for the week. That was its biggest weekly decline since April 2025. Micron Technology, Advanced Micro Devices and Sandisk were among the chipmakers facing renewed selling.
Investors also focused on the growing debt used to finance data centers and AI computing capacity. CoreWeave, one of the so-called neocloud companies, fell nearly 12% Friday. Its weekly decline reached about 25% as traders reacted to concerns about its debt load, which has risen above $51 billion.
Michael Rosen, chief investment officer at Angeles, said investors should continue watching increased debt issuance but argued that the situation was not yet a systemic crisis. His comments reflected the broader debate over whether the AI pullback represents a temporary rotation or the beginning of a deeper reassessment of technology valuations.
Oil Prices and Inflation Create a Dangerous Market Mix
Energy stocks provided one of the few bright spots. West Texas Intermediate crude futures climbed 3.51% to settle at $101.41 per barrel, while Brent crude increased 3.72% to $109.86. Rising tensions involving the United States and Iran, along with continuing conflict between Russia and Ukraine, contributed to the advance.
Chevron and other energy companies gained as higher crude prices supported the sector. Energy stocks rose 2.1% among the 11 S&P 500 sectors, while utilities advanced 1.2%. By contrast, communication services fell 2.7% and information technology declined 2.4%.
Higher oil prices are creating a difficult backdrop for investors because they can lift transportation, production and household costs. Wholesale inflation recorded its largest increase since 2022 this week, while consumer inflation remained well above the Federal Reserve’s 2% target.
The combination of firm inflation and expensive energy could limit the Federal Reserve’s flexibility. Traders interpreted comments from Fed Chairman Kevin Warsh at an International Monetary Fund event in Bangkok as suggesting that policymakers may leave interest rates unchanged at their October meeting. CME Group data showed an 82% probability of no rate change at the October 27–28 gathering.
Market Fear Gauge Jumps as Traders Turn Defensive
The Cboe Volatility Index, or VIX, rose above 22 during the sell-off. The index last closed above 20 in July, and readings above that level generally indicate heightened investor anxiety.
Market breadth was weaker than the headline indexes suggested, although the decline was not universal. About 280 S&P 500 companies finished lower, compared with 222 gainers. The performance showed a clear rotation away from high-growth technology and toward defensive areas such as energy and utilities.
- Nasdaq Composite: Down 2.14% Friday and more than 4% for the week.
- S&P 500: Fell 1.09% to 7,659.44.
- Dow Jones: Declined 0.34% but gained 0.7% for the week.
- SMH semiconductor ETF: Dropped 3% Friday and 10% weekly.
- WTI crude: Settled at $101.41 per barrel.
What Investors Are Watching Next
Investors will be looking for signs that technology stocks can stabilize after the steep weekly losses. Earnings reports, corporate borrowing activity, chip demand and upcoming inflation data could determine whether the sell-off broadens or begins to fade.
The Nasdaq Composite remains highly sensitive to interest rates because many of its companies are valued on expected future growth. If bond yields rise or inflation remains stubborn, investors may continue favoring profitable companies, defensive sectors and businesses with stronger balance sheets.
For now, the market’s message is clear: enthusiasm for AI remains powerful, but investors are demanding more evidence that spending, debt and valuations are sustainable.
