Wall Street enjoyed its strongest session in a month on Tuesday, led by financial and technology stocks after encouraging U.S. factory and construction data suggested the world's biggest economy was regaining momentum.
The S&P 500 closed 2.39 percent higher, leaving the index down 3 percent in 2016 after partly recovering in recent weeks from a steep selloff in January. A rally in Apple shares helped give the Nasdaq Composite its strongest day since August.
While manufacturing activity contracted in February, steadying new orders growth and improving inventories offered signs of stability.
Construction spending in January surged to the highest since 2007, while strong auto sales also boosted sentiment.
The data strengthened expectations the U.S. economy is gaining steam after slowing in the fourth quarter.
"What was the spin since last August? That the Chinese slowdown is going to affect the rest of the world," said Donald Selkin, chief market strategist at National Securities in New York. "Now we're seeing there's virtually no chance we're going to have a recession."
Swings in the price of oil have been tightly linked to stock prices in recent months, and on Tuesday they continued their recovery from recent lows, with U.S. crude CLc1 up 2 percent.

Utilities .SPLRCU, seen as a safe haven in times of trouble, fell 0.49 percent.
