Market Insider | What's Shaking | Stocks to Watch

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."


Tetra Tech – Tech tech company tumbled after it slashed third-quarter earnings guidance to a loss of 30 cents a share to 50 cents a share from a gain of 32 cents a share from 42 cents a share, citing sharply higher restructuring costs.

Vivus – Vivus shares jumped after the company's erectile dysfunction (ED) drug Stendra was found to be effective in less than 15 minutes, according to a new study, compared to other drugs in the multi-billion dollar category that took 1 to 2 hours to take effect.
