Trader Radar - Friday Jan. 25th

Q: On Fast Money’s trader radar we look at the stock that was lighting up screens across Wall Street. As any farmer can tell you, this Peoria, Illinois based company has been moving the earth for them for over 100 years, literally. But they don't just make tractors anymore. Now it's the world’s largest maker of bulldozers, excavators, and mining equipment. And with the China construction boom in full swing ahead of the Olympics investors shouldn't have been surprised by the 11% jump in quarterly earnings Friday. Who is it?

A: Caterpillar is on the Fast Money trader radar. This stock traded double its average daily volume after blowout earnings.
