Tech has been the best performing sector this year, despite recent bouts of volatility on rising valuation concerns. The tech index rose 0.34 percent.
"While valuations overall and for the tech sector isn`t cheap, some of the most powerful earnings growth has come from large-cap technology names," said Bill Northey, chief investment officer at U.S. Bank Wealth Management.
Investors have been counting on earnings to support high valuations for equities. The S&P 500 is trading at about 18 times earnings estimates for the next 12 months, above its long-term average of 15 times.
S&P 500 earnings are expected on average to have grown 10.8 percent in the second quarter, according to Thomson Reuters I/B/E/S.
"We are two-thirds through the earnings season and estimates are going only higher, including for the full year, which is helping support the fundamentals-driven market." said Northey.
