CNBC "Halftime Report" trader Jon Najarian purchased shares of Harley-Davidson on Friday after spotting unusual options activity.

The company is the only major U.S.-based motorcycle manufacturer with $6 billion in annual sales.

In other moves, trader Joe Terranova trimmed his positions in Facebook, Range Resources, EOG Resources and Concho Resources from his model portfolio to take some profits. Terranova also sold his entire position in Palo Alto Networks.
