NEW YORK: The S&P 500 and Nasdaq stock indexes fell from record highs on Monday as uncertainty about progress in U.S.-China trade talks again rose to the fore following comments by President Donald Trump, while a jump in Boeing shares helped the Dow Jones Industrial Average eke out a slim gain.

Investor hopes of a "phase one" trade deal have been a key factor supporting stocks recently, but Trump said on Saturday that the United States would only make a trade deal if it was the "right deal" for America, adding that the talks had moved more slowly than he would have liked.
