Piper Jaffray analyst George Tong names Xerox a 2016 top pick in business services. The company's transformation from a document technology provider to an outsourcing services leader provides "a powerful catalyst for the shares," Tong tells investors in a research note. Further, Xerox's strategic portfolio review along with Carl Icahn's involvement can unlock significant value for the company, the analyst contends. He sees potential upside of over 40% over the next 18 months and reiterates an Overweight rating on Xerox with a $15 price target. The stock closed yesterday up 41c to $10.71.
