The Wall Street Journal reports that Bernstein analyst, Alexia Howard, upgraded the stock of WhiteWave, which sells Silk brand soy and almond milks, Horizon organic dairy products and Earthbound Farm packaged salads, to 'outperform' on Friday to a price target of $56 per share, or more than 20% over its closing price on Thursday. Since the company reported earnings in early August, the company's stock has pulled back by 10%, but, it remains up by 30% for the year, and has more than doubled in value since its listing in 2012. Although the company's climbing stock price could turn away some bidders, Ms. Howard notes that White Wave's highly sought-after product mix and double digit sales growth figures could still attract a number of interested parties.
