S&P 500 hits record highs on AI rebound

The S&P 500 hit another record on Thursday, May 14, 2026, as investors kept buying AI-linked technology stocks even after a hotter U.S. producer inflation reading pushed Treasury yields higher. The benchmark index rose 0.78% to 7,502.04, while the Nasdaq Composite gained 0.88% to 26,635.22, according to market coverage published on May 14. Cisco Systems helped lead the move after its earnings and AI-related commentary, and semiconductor shares extended a rebound that had already lifted stocks a day earlier. U.S. producer prices, meanwhile, rose 1.4% in April from the prior month and 6.0% from a year earlier, the biggest annual gain since December 2022, according to the Bureau of Labor Statistics. ### Which stocks did most of the lifting? Cisco Systems jumped after reporting results and outlining a bigger AI opportunity, and that helped push major indexes higher on May 14. Market coverage from The Motley Fool said Cisco’s earnings-fueled rally helped propel benchmarks to fresh highs, while Bloomberg reported that the company’s gains came after a better-than-anticipated sales forecast and plans to focus more heavily on AI. (fool.com) Nvidia and other semiconductor shares had already helped drive the prior session’s record finish. CNBC reported that on May 13 Nvidia rose more than 2%, Micron Technology gained more than 4%, and the VanEck Semiconductor ETF advanced 2% as traders rotated back into the chip trade. Reuters reported that six of the “Magnificent Seven” AI-related megacaps rose between 1.4% and 3.9% that day. (fool.com) ### Why were record highs notable after the inflation data? The Bureau of Labor Statistics said on May 13 that the producer price index for final demand rose 1.4% in April, after increases of 0.7% in March and 0.6% in February. The annual increase reached 6.0%, and the core measure excluding foods, energy and trade services rose 0.6% on the month and 4.4% on the year. (cnbc.com) Those figures mattered because they strengthened the case for the Federal Reserve to keep policy restrictive. Reuters said on May 13 that hotter-than-expected inflation data increased the probability that the Fed would hold to restrictive monetary policy for the foreseeable future. CNBC reported that traders’ enthusiasm for technology outweighed inflation fears even as other sectors tied more closely to the economy lagged. (bls.gov) ### What did Treasury yields have to do with the move? U.S. Treasury data showed the 10-year yield at 4.18% on May 13, up from 4.15% on May 12, according to the Treasury Department’s daily par yield curve table. That move reflected the same repricing in rates that followed the inflation data. (usnews.com) Charles Schwab said on May 14 that major indexes had mostly shaken off the 6.0% annual gain in producer prices even as long-term yields remained elevated. Schwab also noted that index strength masked weaker breadth beneath the surface, with money continuing to flow into chips and AI-related shares. CNBC similarly reported that roughly two-thirds of S&P 500 components were lower during the May 13 session even as the index finished at a record. (home.treasury.gov) ### Was this a broad rally or a narrow one? The May 13 advance was narrow by several measures. CNBC said about two-thirds of S&P 500 stocks fell that day even though the index rose 0.58% to a record 7,444.25, showing how heavily the benchmark depended on technology leaders. Ross Mayfield, an investment strategist at Baird, told CNBC that investors saw chip demand as structural enough that cyclical macro pressures had not changed the story. (schwab.com) Ryan Detrick, chief market strategist at Carson Group, told Reuters that “in the face of continued hot inflation data, technology remains resilient.” Those comments described a market in which a small group of AI-linked companies continued to dominate index performance. (cnbc.com) ### What comes next for investors watching this trade? The Federal Reserve’s next policy meeting is scheduled for June 16-17, and CME says its FedWatch tool tracks the probabilities of rate changes implied by 30-day fed funds futures. That gives investors a public gauge for how inflation data and Treasury yields are feeding into expectations for the next Fed decision. (cnbc.com) Treasury yields, chip-stock earnings and incoming inflation data remain the next concrete signposts. The producer-price report was released on May 13, and the market’s reaction on May 14 showed that investors were still willing to pay up for AI-linked growth even as rate expectations stayed firm.
