Stocks as well as oil prices rose earlier in the session after data showed China's exports and imports fell less than expected in December, allaying concerns about the health of the world's second-biggest economy. "It's becoming quite apparent that any strength is being used to trim or exit positions as opposed to taking on new positions in the market, at least in the last couple of days," said Ryan Larson, head of US equity trading at RBC Global Asset Management in Chicago. "The overall theme is that people continue to worry about the deterioration in China and, more specifically, the continued erosion in WTI," said Larson.

Express Scripts was down 6.4 percent at $80.09 after health insurer Anthem said it was renegotiating a contract with the pharmacy benefits manager.
