2. The big stock mover on Wednesday was Twitter, which rose more than 7%, its best day since the summer, as the social media company held its first analyst day and made some bullish predictions about its future. Business Insider's Jay Yarow has the full report on comments made by Twitter CEO Dick Costolo regarding some of the company's future plans, but the big news out of its analyst day was this chart from Twitter CFO Anthony Noto. The chart shows Twitter's revenue growing to $14 billion in ten years, and while Noto said this is not a forecast, Jay noted that this is an unusual, and risky, chart and puts a big target on Twitter's back.
