Wall Street stocks posted modest gains on Monday as investors watched developments in U.S.-Iran peace negotiations and cheered the unveiling of a new computer chip that promises to bring artificial intelligence to personal computing.
Tech shares rose 2.5%, boosting the Nasdaq and the S&P 500 to the latest in a series of record closing highs, while the blue-chip Dow closed nominally higher, its gains limited by weakness in all but two of the 11 major S&P 500 sectors.
U.S. President Donald Trump said talks with Iran continue. Earlier, Iran's news agency announced Tehran was halting indirect negotiations with Washington after a new round of strikes threatened to derail diplomatic efforts to end the war, now in its fourth month.
The intensification of hostilities sent crude prices jumping, along with worries over the extent to which a protracted war could accelerate inflation.
"We don't really know where things stand," said Thomas Martin, senior portfolio manager at GLOBALT in Atlanta. "The market seems to think that something's going to get done at some point, but we don't have very good information to go on, like what the Iranians really want and what Trump is willing to settle for."
Stocks added to their gains after Trump said no Israeli troops would go into Beirut, citing a call with Israeli Prime Minister Benjamin Netanyahu.
