Trader Radar - Thursday March 19th

Q: On Fast Money’s trader radar we look at the stock that was lighting up screens across Wall Street. This New York based company dates back to a small book business from the owners' home in the 1800s. These days it’s known for its in-house cafes and access to WiFi. Today this bookseller was a best seller as the stock surged on fourth-quarter numbers. Who is it?

A: On the trader radar tonight we’re watching Barnes & Noble! The nation’s largest bookseller was among the most active names on the NYSE today.
