Wall Street closed lower on Monday, dragged down by tech and industrial stocks. Artificial intelligence (AI) stocks tumbled globally as leading AI CEOs warned rapid development poses risks. Investors grew nervous as the benchmark 10-year Treasury yield topped 5% before the Fed meeting. All of the three benchmark indexes ended in the red.
How Did the Benchmarks Perform?
The Dow Jones Industrial Average (DJI) fell 152.09 points, or 0.3%, to close at 52,421.2. Twenty components of the 30-stock index ended in positive territory, while 10 ended in negative.
The tech-heavy Nasdaq Composite slid 146.63 points, or 0.6%, to close at 26,186.41.
The S&P 500 lost 37 points, or 0.5%, to close at 7,619.98. Eight of the 11 broad sectors of the benchmark index closed in the red. The Technology Select Sector SPDR (XLK), the Industrials Select Sector SPDR (XLI) and the Utilities Select Sector SPDR (XLU) declined 1.7%, 1.4% and 1.3%, respectively, while the Communication Services Select Sector SPDR (XLC) advanced 2.8%.
The fear gauge CBOE Volatility Index (VIX) jumped 8% to 17.1. A total of 15.3 billion shares were traded on Monday, higher than the last 20-session average of 14.8 billion. Advancers outnumbered decliners by a 1.3-to-1 ratio on the S&P 500.
AI Stocks Tumble on Warnings of Rapid Development Risks
AI stocks tumbled globally on Monday, after leaders of Anthropic, OpenAI and xAI cautioned about risks associated with the rapid development of AI technology. The warnings fueled concerns that the industry’s breakneck pace could create technological, regulatory and economic challenges, prompting investors to reassess lofty valuations across AI-related companies.
The selloff extended across major AI-linked stocks, reflecting growing sensitivity toward companies whose valuations have surged on expectations of sustained AI spending and adoption. The cautious comments from prominent industry executives added to broader market uncertainty and raised questions about whether the pace of AI development can be maintained without increasing risks.
Treasury yields climbed sharply on Sept. 14 as investors braced for a potentially hawkish Fed decision. The 10-year yield briefly breached 5%, reaching 5.01%, its highest level since October 2023, before retreating. The 2-year yield rose to around 4.65%, while the 30-year yield hovered around 5.34%.
Oil Prices Rise as Middle East Attacks Threaten Global Supplies
Oil prices settled about 1% higher on Monday as escalating Middle East tensions intensified concerns over global energy supplies. Brent crude futures gained $1.07, or 1%, to settle at $105.68 per barrel, while WTI crude rose $1.34, or 1.3%, to $101.39.
Supply concerns deepened after Yemen’s Iran-backed Houthis attacked Saudi Arabia and Gulf Arab states postponed planned talks with Tehran. Separately, an attack on Saudi Arabia’s east-west oil pipeline disrupted a key export route bypassing the Strait of Hormuz. The outage could threaten as much as 4% of global oil supply, heightening fears of further price pressures.
