US stock indices were mixed on Tuesday as the rebound in Treasury yields offset the extended rally for AI companies.
The S&P 500 and the Dow swung lower, while the tech-heavy Nasdaq 100 rose 0.5% to a record high.
Borrowing costs rebounded in afternoon traded as US President Trump delivered escalatory remarks against Iran in his UN speech, and dimmed hopes of a diplomatic effort to restore fuel exports from the Middle East.
Credit-sensitive banks led the losses, with JPMorgan, Wells Fargo , and Morgan Stanley dropping 4% each.
In turn, another strong session on the AI trade lifted software developers and AI infrastructure companies.
The latest catalyst was the strong reception for Meta's Muse AI agent.
Meta shares were 13% higher in the last two sessions, while Micron gained 3%.
On top of that, Sandisk rose on an upgrade from Rosenblatt.
