Despite the jitters that investors are experiencing as they await the same-store sales numbers that are due out Thursday, there remained some winners in the retail sector today. For the most part, department stores are expected to be the worst of the bunch in June, so it was no surprise Macy's ( M) lost 1.5% to fall to $10.89 in afternoon trading, Sears ( SHLD) fell 5% to $60.37, J.C. Penney ( JCP) shed 2% to hit $26.70 and Nordstrom ( JWN) sank 3% to $18.64. But Kohl's ( KSS) managed to buck the trend after being upgraded by an analyst at Goldman Sachs. Analyst Adrienne Shapira upgraded the department store to buy from neutral, citing Kohl's continued ability to outperform its rivals. Shares in the company rose 15 cents to $42.83. Kohl's wasn't the only retailer upgraded on Tuesday. Dick's Sporting Goods ( DKS) and Jones Apparel Group ( JNY), which operates Nine West and Anne Klein stores, among others, were also upgraded by Goldman Sachs to buy. As a result, shares of Dick's grew 2% to $17.09, while Jones Apparel saw a 4% boost to $9.89 in afternoon trading. Another winner of the day was PriceSmart ( PSMT), which posted a 1.4% increase in June same-store sales. Shares of the warehouse club jumped 4% to $17.08 in afternoon trading. But not everyone was so lucky. BJ's Wholesale Club ( BJ) traded down 2% to reach $31.50 in afternoon trading after Goldman Sacks cut the retailer to sell.
