Edwards Lifesciences (EW -9.2%) is the S&P 500's worst performer after missing on Q4 revenues and issuing a weak Q1 outlook. Wells Fargo cuts shares to Market Perform from Outperform, mostly due to near-term uncertainty around EW's Sapien catheter-delivered heart valve, especially non-U.S. sales. Wells' price target range is cut to $81-83 from $91-93.
