“September’s been the worst retail month in memory,” Jim Cramer said on Tuesday’s “Stop Trading!” segment on CNBC. Cramer does see one opportunity in the sector with Wal-Mart (WMT). He called WMT the “ultimate stock.” “There’s really no other retailer to own other than Wal-Mart. It’s just a gigantic, gigantic buy.” He says Ralph Lauren (RL), Nordstrom (JWN), GameStop (GME) and Philips-Van Heusen (PVH) are all vulnerable in retail. In the oil and gas sector, Cramer said he likes Chesapeake Energy (CHK) and Nabors (NBR). Chat and share ideas with the best small cap traders LIVE each day free at Stocknetworkonline.com
