Wall Street's main indexes were on track for their fourth week of gains on Friday, led by technology and industrial stocks, amid hopes that a bitter trade war between the United States and China would finally come to an end.
Also helping sentiment was the latest data showing US manufacturing output increased by the most in 10 months in December, which could allay fears of a sharp slowdown in factory activity.
The trade optimism was carried over from late Thursday session following a report that U.S. Treasury Secretary Steven Mnuchin was considering lifting some or all tariffs imposed on Chinese imports. The Treasury denied Mnuchin had made any such recommendation.
Trade-sensitive industrials stocks rose 0.85 per cent while the Philadelphia SE semiconductor index climbed 0.55 per cent. A 0.6 per cent rise in technology sector was the biggest boost to S&P 500.
The benchmark index, which closed above its 50-day moving average for the first time since Dec. 3, is now about 11 per cent away from its Sept. 20 record close after having rallied from a 20-month low on Christmas Eve.
"Usually these 'rumors' aren't necessarily untrue, they just aren't true yet, which generally means there is some progress going on but they just don't want to tell anyone yet," said Randy Frederick, vice president of trading and derivatives for Charles Schwab in Austin.
"Whenever you see a major broad market index cross through these moving averages then it tends to result in a small upturn."
