US stocks rose on Monday, boosted by technology and industrial companies, after President Donald Trump said he would delay a planned hike in tariffs on Chinese imports and that he was "very, very close" on a trade deal. Trump said on Monday he was optimistic that a final trade deal could be reached with China and that he would hold a summit to sign any pact, but cautioned an agreement may still not happen.
The US president's move to push the deadline is the clearest sign yet that the two countries are closing in on a deal to end their prolonged trade spat, which has slowed global growth and disrupted markets.
"Extension of the deadline shows that everyone wants to work towards the same goal of reaching a settlement that will help both economies grow," said J.J. Kinahan, chief market strategist at TD Ameritrade in Chicago.
"Markets are taking that as a very positive sign that fears of a slowdown due to tariffs could hopefully be mitigated."
The S&P technology index rose 0.69 percent, with Apple Inc's 1.1 percent rise leading the gains.
Rise in chip companies, which have a big exposure to the Chinese market, helped the Philadelphia semiconductor index climb 1.20 percent.
The tariff-sensitive industrials sector was 0.82 percent higher, helped by Caterpillar Inc's 2.3 percent jump and Boeing Co 0.7 percent rise.
But the sector got the biggest boost from General Electric Co, which leaped 8.8 percent after announcing a sale of its biopharma business to Danaher Corp for $21.4 billion. Danaher shares were up 7.9 percent.
