Semiconductor stocks were again under pressure, this time after SanDisk cut its revenue outlook. Its shares tumbled 18.4 percent to $66.20 and an index of chipmaker shares fell 1.4 percent. The index fell as much as 3.5 percent earlier.
The S&P 500 is still less than 3 percent below its record high hit three weeks ago. The index rallied last week as concern ebbed about an overheating dollar.
Consulting company Accenture's quarterly net revenue rose 5 percent, helped by growth in its outsourcing business as North American companies look to cut costs. Its shares rose 6.8 percent to $94.17.
Red Hat rallied 10.1 percent to $75.36 after it forecast a profit for the first quarter that matched analysts' estimates despite warning about a strong dollar hurting its revenue.
"Earnings, particularly from U.S.-based companies, continue to be very strong," said Doug Foreman, chief investment officer at Kayne Anderson Rudnick in Los Angeles.

Energy stocks on the S&P 500 ended down 0.2 percent despite a rally in crude prices following Saudi Arabia's air strikes in Yemen.
