The year 2013 was a great one for stocks, with the Dow Jones Industrial Average (^DJI 0.05%) returning 30% and the S&P 500 up 32%. But 2014 has had a slow start, and the indexes are down 1% and flat, respectively. So, which companies have been disappointing this year? 

Nike (NKE 0.01%) and Visa (V 1.48%) are the Dow's newest stocks, and they're lagging the index by a wide margin this year. Investors have sold off growth and are looking for better values, and their respective P/E ratios of 24 and 26 have scared investors this year. Goldman Sachs (GS 0.07%) has also underperformed, and it's now considering shutting down some of its proprietary trading to stave off regulatory scrutiny. 

Fool contributor Travis Hoium covers these underperformers, and what to expect throughout 2014, in the video below.
