You're kidding right?
Look a little bit deeper? If you want to invest in a stock that will triple, Sirius is a good bet. It's health is much better than XM and XM has nothing to show that it's going to change. Sirius has more cash, less debt, and now all of the sports programming.
XM has missed the boat and GM was probably the only reason it performed as well as it did. Their values are pretty close to the same and currently Sirius has about half the subscribers that XM has, but that's quickly changing.
At $4 a share it's a good buy, IMO, for 3 years down the road.
