(Updates from 10:16 a.m. ET with closing information.) NEW YORK ( TheStreet) -- Here's what Jim Cramer had to say on CNBC's "Squawk On The Street" Wednesday: Cramer said he's bullish on Radian Group ( RDN) and he wants investors to be in this housing-related stock. Not so with Guidewire ( GWRE) as the cloud computing market has been, well, cloudy, of late. RDN ended Thursday flat but GWRE was up 16.6%. He was also downbeat on First Solar ( FSLR), a stock with "no silver lining." FSLR droped 13.8%. Is there a turn at hand for RadioShack ( RSH)? Cramer said he'll believe that when he sees it. He is more of a believer in Allscripts Healthcare Solutions ( MDRX) because the medical records area continues to be all the rage. RSH was up 7.2% Thursday, with MDRX rising 3.6%. Finally, Cramer said that he'll be interviewing an official of Linn Energy ( LINE) on "Mad Money" tonight and he wants to see if the company is having the same problems as MarkWest Energy ( MWE), which is seeing weakness in natural gas liquids. "We'll get the true answer tonight," he concluded. MWE ended the trading day up 1%.
