Wall Street endured another turbulent trading session on Tuesday as renewed volatility in artificial intelligence-related stocks weighed heavily on major market indexes, offsetting gains in other sectors and highlighting growing investor uncertainty over one of the market’s hottest industries.
The benchmark S&P 500 ended the day down 0.3%, extending its retreat from the record high it reached just one week ago. The index experienced dramatic swings throughout the session, climbing as much as 1% shortly after the opening bell before reversing sharply into a loss of more than 2% during midday trading. It later recovered part of those losses before the closing bell.
The Dow Jones Industrial Average managed to finish in positive territory, rising 86 points, or 0.2%, while the technology-heavy Nasdaq Composite declined 1% as weakness among major semiconductor and artificial intelligence companies dragged on the broader market.
The latest bout of selling was led by companies closely tied to the AI boom, many of which have enjoyed extraordinary gains over the past year but are now facing increased scrutiny over their lofty valuations.
Micron Technology exemplified the market’s volatile mood. Shares initially surged approximately 4% before reversing course and plunging nearly 10% during trading. By the end of the session, the stock closed down 1.4%.
The dramatic intraday reversal followed an equally unpredictable stretch for the memory-chip manufacturer. On Monday, Micron rallied nearly 10%, only days after suffering a decline of more than 13%. Even with those fluctuations, the company’s stock has roughly tripled in value since the beginning of the year.
Such rapid appreciation has fueled concerns among investors and analysts that enthusiasm surrounding artificial intelligence may have driven certain stocks to unsustainable levels. Following last week’s industry-wide selloff, market participants continue debating whether the sector is entering a prolonged correction or simply undergoing a healthy adjustment after months of exceptional gains.
Other prominent AI-related companies also came under pressure.
Marvell Technology fell 7.6% after surrendering early gains, while Advanced Micro Devices declined 3% after also reversing an initial rally. The weakness across chipmakers significantly influenced overall market performance despite strength elsewhere.
The ongoing excitement surrounding artificial intelligence remains evident, however, as several leading companies continue preparing to enter public markets.
OpenAI, the developer behind ChatGPT, announced Monday that it had confidentially filed paperwork with U.S. regulators as part of preparations for a potential initial public offering. Meanwhile, investors continue watching for a possible stock market debut by SpaceX, which could take place later this week.
Outside the technology sector, falling oil prices provided relief for many industries and helped limit broader market losses.
Nearly three-quarters of all companies listed in the S&P 500 finished higher, demonstrating that selling pressure remained concentrated in a relatively small group of high-profile technology names.
Brent crude oil prices dropped 3% to approximately $91.45 per barrel as hopes resurfaced that diplomatic negotiations between the United States and Iran could eventually lead to the reopening of the Strait of Hormuz, a critical global shipping route through which a significant portion of the world’s oil supply passes.
If reopened, tankers carrying crude from Persian Gulf producers would once again be able to move more freely to international markets, potentially easing pressure on global energy supplies and helping stabilize prices.
However, oil markets trimmed part of their losses after President Donald Trump accused Iran of shooting down an American military helicopter near the Strait of Hormuz and declared that the United States “must” respond to the incident, introducing fresh uncertainty into an already fragile geopolitical situation.
The conflict involving Iran has already had broad economic consequences. Elevated energy prices have accelerated inflationary pressures across the United States, increasing costs for consumers and businesses alike while contributing to higher borrowing costs worldwide.
As oil prices eased during Tuesday’s session, Treasury bond yields also edged lower, offering some relief to financial markets.
The yield on the benchmark 10-year U.S. Treasury note slipped to 4.52% from 4.56% the previous day. Even so, yields remain significantly above the 3.97% level recorded before the conflict involving Iran intensified, reflecting persistent concerns about inflation and government borrowing costs.
Investors are now turning their attention to a series of key inflation reports scheduled for release later this week.
The latest Consumer Price Index figures are expected on Wednesday, followed by wholesale inflation data on Thursday. The reports are likely to play an important role in shaping expectations for future monetary policy decisions by the Federal Reserve.
Many traders currently believe the central bank may still need to raise interest rates at least once before the end of the year, citing stubborn inflation and continued resilience in the U.S. labor market.
Higher interest rates can help slow inflation by reducing demand throughout the economy, but they also tend to increase borrowing costs for businesses and consumers, potentially slowing economic growth and putting pressure on stock valuations.
The impact is already being felt in housing markets, where average long-term mortgage rates have climbed to their highest levels in roughly nine months.
Higher financing costs could also affect one of the economy’s fastest-growing sectors by making it more expensive for companies to build the massive data centers needed to support artificial intelligence technologies and cloud computing infrastructure.
Despite the weakness in technology shares, several companies posted notable gains driven by industry-specific developments.
Airline stocks benefited from the decline in oil prices, as lower fuel costs generally improve profit margins for carriers. American Airlines rose 3.6%, while Delta Air Lines advanced 3.8%.
Food manufacturer J.M. Smucker delivered one of the strongest performances of the day, jumping 10.4% after reporting quarterly earnings that exceeded analysts’ expectations. The company, known for brands including Folgers coffee and Hostess snack products, credited higher prices for coffee and baked goods with helping boost profits.
Its results added to a growing list of American corporations reporting stronger-than-expected earnings, a trend that has supported the stock market’s record-setting performance throughout much of the year.
Meanwhile, biotechnology company Nuvalent surged 39.3% after pharmaceutical giant GSK agreed to acquire the company in a deal valued at approximately $10.6 billion. Shares of GSK traded in New York also moved higher, gaining 1.2%.
By the close of trading, the S&P 500 had fallen 19.08 points to finish at 7,386.65. The Dow Jones Industrial Average rose 86.10 points to 50,872.11, while the Nasdaq Composite dropped 250.84 points to end the session at 25,678.82.
Overseas markets presented a mixed picture.
European stock indexes finished modestly lower, while Asian markets experienced larger swings. South Korea’s Kospi index rallied 8.2%, recovering nearly all of the steep 8.3% decline recorded during the previous trading session.
The South Korean market’s sharp movements reflected the performance of major technology companies such as SK Hynix and Samsung Electronics, whose shares remain closely linked to global investor sentiment surrounding artificial intelligence and semiconductor demand.
Tuesday’s trading session underscored the increasingly volatile environment facing investors as optimism over artificial intelligence collides with concerns about elevated valuations, persistent inflation, geopolitical tensions and the prospect of tighter monetary policy, all of which continue to shape the direction of global financial markets.
