March 15 (Reuters) - Wall Street's main indexes hit session highs on Friday, in broad based gains led by technology stocks, as sentiment was lifted by an upbeat note in trade talks between the United States and China.
China's state-run news agency said Washington and Beijing were making further substantive progress on trade talks. The report came as a relief after news that a summit to seal a deal between the two sides will not happen at March-end.
Chipmakers, which get a large portion of their revenue from China, rose, with the Philadelphia SE chip index up 2.87 percent, while the broader technology sector rose 1.61 percent.
Broadcom Inc jumped nearly 8.9 percent and was the biggest boost to the S&P and Nasdaq, after the company's quarterly profit beat analysts' estimates.
"Chipmakers are greatly linked to China, so when we have positive news out of semiconductor space it is a reaffirmation that the fundamentals of tech are still strong," said Jeff Kravetz, regional investment strategist at U.S. Bank Wealth Management in Phoenix.
"We know that trade is a work in progress, but it looks like we're getting closer to an initial trade agreement and that is helping markets."
