Take a look at some of Wednesday's midday movers:
bluebird bio – The biotech IPO surged more than 50 percent above its $17 offering price. The company works on gene therapy for "sever genetic and orphan diseases."
Men's Warehouse – Founder and Executive Chairman George Zimmer was terminated by the company's board of directors. Men's Warehouse was scheduled to hold its shareholder meeting Wednesday, but the event has been delayed so the company can put together a new slate of directors. Men's Warehouse has not commented on the reason for its move, while Zimmer said in a statement that "the Board has inappropriately chosen to silence my concerns (about the direction of the company) through termination as an executive officer."
