The three main U.S. indexes climbed to fresh record-highs for the fourth day in a row on Thursday, fueled by gains in technology stocks including Netflix, Microsoft and Amazon.com.
Nine of the 11 major S&P indexes were higher, led by the information technology sector. Tech stocks, which have powered much of the recent rally, have risen about 26 percent this year.
"Investors are planning years in the future and so I don`t think valuation (of tech stocks) really matters to the people who are buying them as a momentum sort of investing play," said Kim Forrest, senior equity research analyst at Fort Pitt Capital Group in Pittsburgh.
Data on Thursday pointed to underlying strength in the economy despite weather-related disruptions, with the trade deficit narrowing in August and jobless claims falling more than expected last week.
New orders for goods made in the United States rose in August and orders for core capital goods were stronger than the previous figures.
"We are continuing to get good economic news globally, specifically out of the U.S.," Forrest said. "It looks like the U.S. economy continues to expand and that is what is driving today."
Focus will now shift to the more comprehensive monthly jobs report, which is due on Friday.
Investors are also gearing up for the upcoming third-quarter corporate earnings season.
