NEW YORK, Feb 12 (Reuters) - U.S. stocks ended sharply higher on Thursday, with a rally in technology stocks leading the Nasdaq to a 15-year high, while a ceasefire agreement between Russia and Ukraine also eased tensions.
The day's gains were broad, with eight of the 10 primary S&P 500 sectors rising, and the S&P information technology sector rose 1.6 percent in its third straight daily advance. Cisco Systems climbed 9.4 percent to $29.46 in the network equipment maker's biggest one-day jump since May 2013 after earnings and revenue beat expectations.
TripAdvisor Inc soared 22.5 percent to $82.40 a day after revenue topped forecasts. Fellow online travel company Expedia jumped 14.5 percent to $89.57. Earlier, Expedia agreed to buy Orbitz Worldwide for about $1.33 billion.
With 76 percent of the S&P 500 having reported, about 71.4 percent of companies have topped earnings expectations, according to Thomson Reuters data, while 56.8 percent have topped on revenue. That compares to the long-term average of 63 percent for earnings and 61 percent for revenue. Continuación...
