Trader Radar - Thursday Aug. 21st

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 began in the 1800s as a printing company however now it’s best known for its shops with in-house cafes and access to Wi-Fi. If you’re looking for a happy ending look elsewhere; the stock was a horror story today, after the company gave a weak sales forecast. 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.
