Recession fears have put the S&P 500 on track for the worst start to January in history. The Dow closed down 59 points and the NASDAQ lost 6 points. The team at CNBC's "Fast Money" try to help investors understand the movements in the market and Brian Schaeffer visits the show to give insight into Apple.Karen Finerman mentioned she bought back a lot of short positions Friday on names like Lehman Brothers Holdings ( LEH) and Simon Properties ( SPG). Pete Najarian advised investors and traders to take profits on short positions that have worked. He disclosed that he took 50% of his put options trades off the table, but he does still see problems ahead for the market. Guy Adami explained how some of the defensive names were sold off Friday and that leads him to believe we are closer to the end of the selling than we were a few days ago.
