(Reuters) - Facebook's 9.4 percent jump after blockbuster results and gains in chipmakers powered technology stocks on Thursday, with easing U.S. bond yields helping the sentiment on Wall Street.
The S&P technology index rose 2.2 percent, the biggest gainer among the 11 major S&P sectors, and was on track to break its six-day losing streak. Only six stocks in the 69-member index were in the red.
The gains come after U.S. equities were pressured by a rise in the 10-year Treasury yield to 3 percent on Tuesday, a level it last hit in 2014, stoking fears about rising inflation and corporate costs.
"The rising yields are having an impact and there are some concerns that we're in an environment where we're seeing a peak in terms of earnings growth," said Emily Roland, head of capital markets research at John Hancock Investments in Boston."
"But some of these factors are overshadowing the fact we have sturdy fundamental backdrop, both earnings and economic."
Facebook (NASDAQ:FB) reported a strong 63 percent rise in profit and an increase in users, with no sign that business was hurt by a scandal over the mishandling of personal data.
Amazon (NASDAQ:AMZN) which is set to report after the closing bell on Thursday, was up 3 percent.
Of the 227 S&P 500 companies that have reported first-quarter earnings so far, 79.7 percent topped profit estimates, according to Thomson Reuters data. Analysts now expect earnings growth of 23.1 percent, compared with 18.6 percent at the start of the season.
"We're seeing interest rates go up ... but what we're seeing today is fundamentals winning the argument," said Kevin Miller, chief executive officer of E-Valuator Funds in Bloomington, Minnesota.
Supporting the equities, the 10-year yield dropped below the 3 percent mark. [US/]
