Wall St. rises as earnings jitters recede and oil rebounds

(Reuters) - U.S. stocks rose on Wednesday, fueled by gains in the energy sector and speculation that upcoming first-quarter earnings reports might not be quite as bad as previously thought.

All 10 major S&P 500 sectors rose, with the energy index <.SPNY> up 1.89 percent. U.S. crude jumped more than 4 percent after a lower-than-expected build of crude stockpiles in the United States.

Investors have feared that the March-quarter earnings season, just getting under way, would be hurt by low oil prices, a strong dollar and extreme weather in the eastern United States. First-quarter profits for S&P 500 companies are seen dropping 2.6 percent, according to Thomson Reuters data.

But of the 36 companies in the S&P 500 that have reported so far, 81 percent beat expectations, better than the 63 percent of companies exceeding expectations in a typical quarter.

"Management has done a good job guiding market expectations to an appropriate level, and now they're stepping over a lowered bar," said Alan Gayle, senior investment strategist and director of asset allocation at RidgeWorth Investments in Atlanta, Georgia. "Fundamentals in the equity market remain good."
