NEW YORK: Wall Street stocks were mostly lower at the end of a choppy session Tuesday, digesting solid results from US banks and a pullback in Asian markets prompted by worries over the AI investment boom.

While JPMorgan Chase missed analyst estimates, the US banking giant joined three other large US banks in reporting year-on-year profit increases that pointed to continued health in the US consumer.

JPMorgan Chief Financial Officer Jeremy Barnum described US consumer spending as "sort of robust," adding that the consumer credit picture remains "quite resilient" despite persistent inflationary trends.

The strong bank earnings gave some support to Wall Street indices, although investors remained cautious ahead of Wednesday's consumer price index data, a key input to upcoming Federal Reserve decisions.
