Apple (AAPL.O) was the biggest positive for the S&P 500 and Nasdaq. It rose 1.6 percent to $98.53 after reports that its music streaming service hit the 10 million-subscriber mark in six months.

Stocks turned up late in the session, and the CBOE Volatility Index .VIX - Wall Street's fear gauge - finished down 10 percent.
"The market is very stretched to the downside. Being oversold doesn't mean it's over, but nonetheless these things only go so far before you get at least some kind of relief rally," said Frank Gretz, market analyst and technician for Wellington Shields & Co. in New York.
The S&P energy sector .SPNY dropped 2.1 percent following another sharp drop in oil prices, while the health sector .SPXHC declined 1.2 percent. Among materials stocks, Freeport-McMoRan (FCX.N) tumbled 20.3 percent to $4.31.
