"Crazy" Jim Cramer of CNBC's Mad Money says XM Satellite Radio (XMSR) and SIRIUS Satellite Radio (SIRI) are overvalued, and the satellite Radio industry as a whole has "peaked".

Citing market capitialization as too large, and pointing to XM's recent miss in subscriber number targets, Cramer says XMSR and SIRI only represent value now if they merge.

Cramer says on the short term, he would be long SIRI and short XMSR.

I'll agree on long SIRI and short XMSR but, I don't think mergers are where the butter for this bread lie, at least not yet. SIRI needs to capitalize and expound upon the recent gains it has made against XMSR in the market. SIRIUS has been on a rampage lately, and XM is facing some difficult and bumpy roads ahead in the form of lawsuits and legal battles.

If SIRIUS can launch useable and relevant video feeds soon, and well ahead of XM, they will have established a strong foothold in a market that didn't exist 3 years ago. History is written by the victorious, and I think SIRIUS will be writing the book on how Satellite Radio killed FM.
