U.S. markets ended Wednesday's session mixed as traders digested mixed data on the economic front. Albert Fried Managing Director Ben Willis says there was confusion in the markets and traders are sitting on the sidelines waiting for Friday's January jobs report. Willis says one bright spot were shares in pharmaceutical stocks. Willis says the VIX, which is a widely tracked measure of market sentiment, suggest there is more volatility ahead. 'More volatility,' Willis says, means the market is in 'correction mode.' TheStreet's Ruben Ramirez reports from the NYSE.
