AI Stocks Lead Markets Higher as Cooling Inflation Eases Rate Fears
U.S. stocks finished higher today, with the Nasdaq leading gains as investors returned to AI and technology shares. The S&P 500 rose 0.58%, the Nasdaq climbed 0.91%, the Russell 2000 gained 0.57%, and the Dow Jones Industrial Average edged up 0.05%.
Technology and AI-related stocks once again drove much of the market’s upside. Semiconductor and memory names rebounded strongly after Wednesday’s pause, while software stocks also rallied sharply following strong earnings and upbeat AI commentary from Snowflake. Microsoft was another standout after reports suggested the company is preparing to unveil new AI coding models at its Build conference next week, reinforcing optimism around the next phase of enterprise AI adoption.
Markets also continued responding positively to developments surrounding the U.S.-Iran situation. Reports suggested negotiators had reached a preliminary 60-day ceasefire framework agreement, though President Trump has not yet formally approved the deal. Investors nevertheless interpreted the headlines as another sign that tensions may gradually ease. Oil prices remained relatively contained, Treasury yields moved lower again, and volatility indicators continued falling.
Economic data was mixed but generally supportive for markets. Core PCE inflation — the Federal Reserve’s preferred inflation measure — came in slightly cooler than expected at 0.2% month-over-month, helping calm some inflation concerns. Treasury yields declined again, with the 30-year yield falling for a sixth straight session and moving back below 5%.
However, the broader economic picture still showed signs of slowing beneath the surface. Personal income unexpectedly came in flat, GDP growth for the first quarter was revised lower to 1.6%, and new home sales missed expectations. Initial jobless claims also ticked slightly higher. While inflation pressures may be easing somewhat, growth data continues to soften.
Corporate earnings remained a major driver of stock moves. Snowflake surged more than 36% after delivering strong product revenue growth and highlighting accelerating AI demand. Dollar Tree, Kohl’s, Best Buy, and Agilent also posted strong gains after earnings reports that exceeded expectations. Marvell rose after raising its long-term AI-related revenue outlook, though some investors felt expectations had already become extremely high after the stock’s massive rally this year.
On the downside, semiconductor supplier Photronics plunged after disappointing earnings and weaker guidance, while Synopsys fell despite beating estimates, reflecting just how elevated expectations have become in many AI-related stocks.
Here’s Our Take
Today’s market action reinforced two themes that continue to dominate investor sentiment: AI optimism and easing geopolitical fears. The AI trade remains incredibly powerful. Investors continue rewarding companies tied to semiconductors, cloud computing, enterprise software, and AI infrastructure spending. Even after a massive run higher, the market still appears willing to buy dips in the sector as earnings and guidance continue validating the long-term growth story.
At the same time, falling Treasury yields and hopes for a U.S.-Iran agreement are helping remove some of the biggest macro overhangs that pressured markets earlier this month. Lower oil prices and cooling inflation expectations are giving investors confidence that the Fed may not need to become even more aggressive from here.
However, there are still important risks beneath the surface. Today’s economic data showed signs of slowing growth, weaker income trends, softer housing activity, and still-sticky inflation. Valuations in many AI-linked stocks are also becoming increasingly stretched, and market breadth remains relatively narrow despite the broader indexes hitting new highs. For now, momentum remains firmly bullish. But markets are still walking a fine line between optimism around AI-driven earnings growth and concerns that the economy may be gradually slowing underneath the surface.
