Trader Radar - Thursday Apr. 10th

Q: On Fast Money’s trader radar we look at the stock that was lighting up screens across Wall Street. Britney Spears once crooned about the age where you're not a girl but not yet a woman. And this retail company’s two chains cater to this exact demographic. But just as unpredictable as the girls they serve, this stock had a huge mood swing today, falling more then 18% on first quarter guidance. Who is it?

A: On the Trader Radar tonight we’re watching Tween Brands . Shares of this retailer traded more then five times its average daily volume today.
