US STOCKS - S&P 500 Ends Lower, Weighed Down by Nvidia Dip

WALL STREET - Aug 26 (Reuters) - The S&P 500 finished lower on Monday, with AI heavyweight Nvidia dipping ahead of its quarterly report this week, while investors awaited inflation data for clues about the path of interest-rate cuts by the Federal Reserve.

The tech-heavy Nasdaq also declined, but the Dow Jones Industrial Average was supported by gains in Caterpillar and American Express and finished just slightly up.

Nvidia dropped ahead of its report on Wednesday in what is set to be the U.S. stock market's most closely watched event of the week.
