Tech sector surges 5.4% as AI stocks lead Monday rally

The U.S. Information Technology Index surged 5.44% on Monday, its biggest single-day gain in recent months, as artificial intelligence stocks powered a broad tech rally.

The S&P 500 information technology sector surged 5.44% to 460.94 on Monday, driven by a broad rally in artificial intelligence-linked stocks.

"Confidence in the strength of the rally has been shaken by Tuesday's reversal, and it is now a case of 'once bitten, twice shy,'" Chris Beauchamp, chief market analyst at IG, said of the subsequent pullback.

The AI Winners Index jumped 5.65% to 448.13, while the AI Software Pioneers Index rose 2.19% to 110.89. The North American Tech Software Sector ETF gained 2.20% to close at $92.68. The rally came as investors piled into technology names ahead of key inflation data due later in the week.

The move marked a sharp contrast with the broader market's performance later in the week. The Dow Jones Industrial Average fell 954 points, or 1.9%, to 49,919 on Wednesday after the May consumer price index showed annual inflation accelerated to 4.2%, the fastest pace in more than three years. The S&P 500 dropped 1.6% to 7,267, while the Nasdaq Composite slid 2% to 25,170.

The inflation reading, driven in part by rising energy costs as tensions escalated in the Middle East, prompted traders to reassess expectations for Federal Reserve policy. Some investors began pricing in the possibility of another rate hike later this year, according to fed funds futures data.

Tech Leads as AI Momentum Accelerates

The Monday rally was concentrated in AI-related names, with the AI Winners Index outperforming the broader tech sector by 21 basis points. The move extended a trend that has seen the AI Winners Index gain more than 11% year-to-date, according to the OpenVC 500 Index tracked by NYSE.

The rally coincided with several positive catalysts for the AI sector. OpenAI filed confidentially for an initial public offering, the company announced Monday, adding to momentum after rival Anthropic also filed to go public. OpenAI, valued at $852 billion post-money, reported roughly 900 million weekly active users.

Cross-Asset Context

The tech rally unfolded against a backdrop of elevated oil prices, with West Texas Intermediate crude trading near $90 per barrel as tensions between the United States and Iran over the Strait of Hormuz continued. The U.S. 10-year Treasury yield moved higher as traders priced in a higher-for-longer rate environment, while the U.S. dollar index strengthened.

The rotation into technology came as investors weighed the implications of sticky inflation against strong corporate earnings. The S&P 500's information technology sector has been the top-performing sector year-to-date, outpacing communication services and consumer discretionary.
