XM subscriber costs were WAY higher than expected. SIRI will announce tomorrow their Q4 and their own acquisition costs.
This stock is going to JUMP. In the near term, expect 20 - 30% run up. In the long term, expect it to catch and pass XMSR in share price and market cap. They are beating XM and polls are showing that most people NOW equate Sirius with satellite, rather than XM. XM's subscriber acquisition costs are going to CONTINUE to go up, while Sirius will be accelerating growth by leaps and bounds.
It's down today in sympathy with XM. This is where you beat the sheep on the street!
