Sirius ( SIRI) is going to $5 a share when the XM Satellite ( XMSR) merger gets approved, Jim Cramer said Monday on CNBC's Stop Trading! segment. Cramer said he believes the deal will get approved this year in spite of the fact that the all-stock agreement "has been topic one for Congress" for months. Sirius traded recently at $3.60. Cramer also said Crocs ( CROX) is up 4% because of a huge short squeeze, though he still likes the stock in the long term.
