S&P 500 Hits Record High as Tech Surge Masks Broad Market Weakness

CNBC reported Wednesday that the S&P 500 record high masked deep divisions in the market, with technology stocks powering the index upward even as roughly two-thirds of its members finished the session in the red.

Tech and Chips Steal the Show

The S&P 500 gained 0.7% to reach a fresh intraday all-time high. The Nasdaq climbed 1.4%, while the Dow Jones Industrial Average dropped 86 points, or 0.2%, weighed down by concerns over persistent inflation.

Nvidia shares advanced more than 2%, while Micron Technology added over 3%. The VanEck Semiconductor ETF rose 2% on the day. Apple crossed the $300 per share threshold for the first time, touching an intraday peak of $300.49.

Baird investment strategist Ross Mayfield told CNBC that demand for chip stocks has taken on a momentum of its own. Investors appear to view the structural growth story behind artificial intelligence as largely immune to the broader macroeconomic headwinds, he said.

Inflation Data Clouds the Outlook

The session unfolded against a difficult inflationary backdrop. The April producer price index jumped 1.4%, the largest single-month increase since March 2022. Economists polled by Dow Jones had forecast a 0.5% rise. Annual wholesale inflation came in at 6%, above the 4.9% consensus and the highest reading since late 2022.

Higher energy prices tied to the ongoing conflict in Iran weighed on consumer-facing and cyclically sensitive sectors. Shares of Home Depot and JPMorgan were among the notable decliners.

Background: A Market Riding Two Competing Narratives

Semiconductor and AI-related stocks have led the broader market recovery in recent weeks, fueling back-to-back index records. But Tuesday’s hotter consumer inflation print had already knocked both the S&P 500 and Nasdaq briefly off their highs.

The latest policy backdrop adds complexity. Nvidia CEO Jensen Huang accompanied President Donald Trump on his visit to China, where Trump met with President Xi Jinping. Mayfield said the trip raised investor hopes that Nvidia could eventually resume chip sales to Chinese markets, though he characterized expectations for concrete progress as still modest.

Momentum May Be Running Out of Road

Despite the headline record, Mayfield struck a cautious note. He warned that AI-trade investors could eventually reassess their positions if the wider economic environment deteriorates further. The promise of a swift end to inflationary pressures tied to the Iran conflict has not materialized, he noted, and profit-taking could follow.

Twenty-seven S&P 500 members hit new 52-week highs Wednesday, including Apple and Cisco. Yet 44 stocks touched new 52-week lows on the same day, underscoring how narrow the rally has become.
