Oct 11 (Reuters) - Wall Street rose for the third straight session on Friday, as investors expected top-level trade talks between the United States and China to result in a partial trade deal and delay planned U.S. tariff increases.
Shares of Apple Inc hit a record high and were the biggest boost to the S&P 500 and Nasdaq, while the technology sector was headed for its best day in five weeks.
President Donald Trump said the trade negotiations were going well, and he would meet Chinese Vice Premier Liu He later in the day. The top-level discussions enter their second day on Friday.
Analysts said equity markets have grown hungry for some sort of breakthrough in the latest round of negotiations.
"Over the last couple of months, we have seen firms taking a hit from the uncertainty around trade and markets will be looking for any clues to remove that uncertainty," said Scott Brown, chief economist at Raymond James in St. Petersburg, Florida.
"It is still going to be a one step forward, two steps backward tone with the talks, but there are hopes of a de-escalation."
