Buy Reliance Steel ( RS) off the big deal between U.S. Steel ( X) and Lone Star ( LSS) deal, Jim Cramer said Thursday on CNBC's "Stop Trading!" segment. Cramer said Reliance, up 3% Thursday afternoon, is "the cheapest that's left" among the consolidation-crazed steel names. Of the U.S. Steel plan to acquire Lone Star, Cramer said, "What a deal." Cramer likes GlobalSantaFe ( GSF), saying a "monster seller" in the stock is giving investors an opportunity to "take advantage of the weakness" that has the stock down fractionally Thursday. Cramer believes Norway's SeaDrill could end up buying or merging with GlobalSantaFe. Cramer likes Tata Motors ( TTM), the Indian auto play, and is taking a look at Frozen Food Express ( FFEX) and RadioShack ( RSH) on Bob Olstein's advice.
