    Okay folks, here's a look at the stocks that you are trading and the ones that are paying off--and the one's that aren't. The info is from Thursday's close. Some of the "usual suspects" are still on the lists but COMS seems to be a new player in the most active. PALM is one of the most active, but as you can see--not paying off that well. ARXT is making investors happy. Widely helds are pretty much what they have been lately. And FYI: Contest registrations to date: 415,962.
