Stocks End the Week Lower as the AI Selloff Deepens and Rising Oil Prices Add to Market Uncertainty
Stocks ended the week lower today, with the S&P 500 declining 1.01%, the Nasdaq falling 1.40%, the Dow dropping 0.77%, and the Russell 2000 slipping 0.42%. All four major indexes also finished the week in negative territory.
Technology and AI-related stocks remained the main source of weakness. Semiconductor shares continued their sharp pullback, with the group now more than 20% below its June peak. Meta, Alphabet, Tesla, and other large technology companies also declined, while banks, airlines, homebuilders, retailers, and media companies came under pressure. Energy, insurance, healthcare, railroads, and grocery stocks held up better than the broader market.
The recent decline in semiconductor and AI infrastructure stocks still appears to be driven partly by investors taking profits from one of the market’s most crowded trades. However, concerns are also growing around the enormous amount of spending required to build AI infrastructure, increased competition from Chinese and open-source models, expanding chip and memory production, and whether future earnings can justify current valuations.
Higher oil prices added another challenge. Crude oil rose 4.5% on Friday and recorded its strongest weekly gain since April as tensions between the United States and Iran remained elevated. Reports that the United States may support additional military action raised concerns about further disruption to shipping and energy supplies. Markets still expect diplomacy to eventually prevail, but neither side currently appears eager to compromise.
Corporate earnings were mixed. Netflix declined after reporting slower North American revenue growth and offering a softer outlook for the current quarter. Intuitive Surgical fell despite beating earnings expectations because U.S. procedure growth slowed. Travelers delivered strong results as catastrophe losses declined, while Alcoa’s results were affected by weaker aluminum prices late in the quarter.
Economic data was somewhat more encouraging. Consumer sentiment improved more than expected in July, helped by lower gasoline prices earlier in the month, while short-term inflation expectations declined. Housing starts also rose sharply, although the increase was concentrated in multifamily construction, while single-family homebuilding remained weak. Industrial production was positive but slightly below expectations.
Here’s Our Take
Today’s decline reflected a broader move away from risk rather than the healthier sector rotation seen earlier in the week. The sharp pullback in semiconductor stocks is meaningful, but it does not necessarily indicate that the long-term AI investment story has broken down. Strong results and spending plans from companies such as Taiwan Semiconductor and ASML continue to show that demand for advanced computing infrastructure remains substantial.
The more immediate concern is that expectations and investor positioning became too aggressive. Even companies with strong fundamentals can experience sizable declines when valuations are elevated and too many investors are positioned in the same trade. Continued volatility in AI-related stocks should therefore not be surprising.
The broader economic picture remains relatively stable. Inflation data improved this week, consumers are feeling somewhat better, and the labor market and overall economy continue to expand. However, rising oil prices could complicate that progress if geopolitical tensions persist and begin pushing gasoline, transportation, and other costs higher again.
With the Federal Reserve likely to leave interest rates unchanged later this month, attention will now shift more heavily toward corporate earnings. Investors will be looking for evidence that strong AI spending, resilient consumer demand, and healthy profit growth can continue to support the market despite elevated valuations and geopolitical uncertainty.
