Wall Street ends higher but indexes post weekly losses

A sharp rally in crude oil and energy shares lifted U.S. stocks on Friday, but indexes registered losses for the week. U.S. crude oil settled more than 6 percent higher after data showed lower U.S. stockpiles, driving gains of 2 percent in the S&P energy index . Investor focus should shift next week from oil and the Fed to quarterly reports, said Peter Kenny, senior market strategist at Global Markets Advisory Group, in Berkeley Heights, New Jersey.
