Pacific Crest analyst Evan Wilson downgraded Twitter to Sector Weight following the company's Q4 results citing a lack of confidence in its turnaround. Twitter management's five-point plan for 2016 is unlikely to attract new or lapsed users, Wilson tells investors in a post-earnings research note. The company has "set a new historical precedent in failing to inspire any improvement in investor sentiment with a new vision," the analyst contends. He sees potential downside risk to $11 per share. The stock is trading down 9% to $13.65 in the pre-market.
