Trader Radar - Wednesday January 14th

Q: On Fast Money’s trader radar we look at the stock that was lighting up screens across Wall Street. Founded in 1996 by a former University of Maryland football player, this company set out to create a sweat-free T-shirt for athletes. The company has since taken athletic apparel one step further, by eliminating pesky labels with its lockertag heat seals. But today the maker of athletic apparel couldn’t quite perform, and investors felt the heat as the stock plummeted on disappointing fourth-quarter earnings results. Who is it?

A: On the trader radar tonight we’re watching Under Armour ! The maker of athletic clothing was among the most active names on the NYSE today.
