NEW YORK, May 26, 2026, 16:05 EDT
Dow drops as S&P 500, Nasdaq climb on AI chip gains The Dow Jones Industrial Average closed down 173.90 points, or 0.34%, at 50,405.80 on Tuesday. Blue chips lagged behind after AI-linked chip stocks drove higher moves in the S&P 500 and Nasdaq. The S&P 500 added 0.57% and the Nasdaq Composite climbed 1.05%, Reuters reported.
The split became a focus as trading picked up again after the Memorial Day break, with the Dow coming off a record close in the previous session. The New York Stock Exchange says May 25 is a full holiday in 2026, with regular hours set to end at 4 p.m. Eastern. The Dow finished Friday at 50,579.70, its highest close.
The Dow is price-weighted, so swings in higher-priced names impact the index more than the same move in a cheaper stock. On Tuesday, that set the Dow apart from the S&P 500 and Nasdaq, which saw clearer gains as chip stocks jumped.
Micron showed the move. The memory-chip maker hit a $1 trillion market cap for the first time, briefly, after UBS bumped its price target on the stock to $1,625 from $535. The Philadelphia semiconductor index climbed about 5% to a new high. Qualcomm rose after a report on a possible chip agreement with ByteDance. Marvell was higher too, with AI-related names still driving growth stocks.
Tech rallies this year are “reminiscent of the boom at the end of the 1990s,” Chris Zaccarelli, chief investment officer at Northlight Asset Management, said. He said lessons from the tech bust after that boom could help some investors sidestep another round, though the market is still ready to pay up for AI exposure. Reuters
Micron’s run brought fresh attention to memory chips in the AI push, not just graphics processors. These chips handle data storage and movement in AI servers, and Art Hogan, chief market strategist at B. Riley Wealth, said “Micron sits at the center of it” as demand for data centers keeps growing. While Nvidia, Samsung and SK Hynix are still major competitors in the supply chain, Micron led the trade on Tuesday. Reuters
The Dow didn’t get the same boost. UnitedHealth and Chevron pulled on the index earlier, with other healthcare stocks adding pressure. The Dow lagged even as chip stocks ran and market breadth improved.
Oil moved lower as geopolitics stayed in focus. U.S. crude dropped 2.81% to close at $93.89. Brent finished at $99.58 after U.S. launched strikes on Iranian targets, with the market still watching talks over a possible U.S.-Iran agreement. “The market’s not really sure what should happen,” said Sam Stovall, chief investment strategist at CFRA Research. That summed up the day’s mixed signals. Reuters
Bonds helped stocks out a bit. The 10-year U.S. Treasury yield dropped to around 4.5%, with the two-year also down. When yields pull back, stocks can look better, though traders said the move showed some caution as well as relief.
Consumer confidence fell in May as new data came in soft. The Conference Board’s Consumer Confidence Index dropped to 93.1, down from 93.8 after revision. Households cited worries about prices due to the Middle East conflict. Dana M. Peterson, chief economist at The Conference Board, said the “inflationary impacts of the war in the Middle East intensified.” The Conference Board
This isn’t a straightforward breakout. If Iran talks fall apart or energy prices push higher, inflation concerns could resurface fast, dragging on rate-cut bets and adding more strain for consumers and tech stocks with high valuations. “Americans were still ‘trying to stretch every dollar,’” said Heather Long, chief economist at Navy Federal Credit Union. The stock rally hasn’t translated to household comfort. Reuters
The next thing to watch is if the rally spreads out from semis. Investors want more signs in tech earnings, with Marvell and Dell up next after Micron’s jump changed the mood for the AI hardware group. The Dow faces a simpler test: whether old-economy names can get moving, or if the index stays trailing a market where chips keep leading.
