Updated from 9:13 a.m. ESTThough a large number of retailers reported solid February same-store sales Thursday, many of the stocks showed little or nothing for it. Lynn Mander, a portfolio manager at Bryn Mawr Trust Wealth Management, thinks the monthly sales information was already priced in, and said the stocks could be correcting after a postholiday run-up. Typically, stock prices are higher going into spring after lagging during the holiday season when investors are usually concerned about how strong the holiday season will be, Mander said. A broad measure of the reaction, S&P's retail index, was lately off 1.74 points, or 0.4%, at 397.75. Of individual retailers, Wal-Mart ( WMT), the world's largest retailer by revenue, reported that same-store sales increased 6.2%, which was above its own estimate, and superior to a 2.6% increase in the same period last year. Net sales at increased 14% to $20.2 billion. Same-store sales at the company's Sam's Club division increased 7.5%, while total sales in the unit were up 10.4% to $2.7 billion. International division sales jumped 22.2% to $3.9 billion. Wal-Mart said it expects same-store sales in March to rise 4% to 6%. Shares of the company were lately up 24 cents, or 0.4%, at $60.60. Target ( TGT) also beat expectations with a 7.5% increase in same-store sales. Total sales in the period increased 13% to $3.31 billion. Of note, both Mervn's and Marshal Field's, divisions of Target, posted positive same-store sales; the units have largely been reporting negative results in the last three years. Mervyn's and Marshall Field's have "been a real cement block around Target's foot for quite a while," Mander said. Shares of Target were up 36 cents, or 0.8%, at $43.95. Rounding out the major discount stores, Costco ( COST) had reported on Wednesday that same-store sales increased 11%, while BJ's Wholesale Club ( BJ) had said that same-stores sales rose 7.9%. Shares of Costco were down 31 cents, or 0.8%, at $38, while BJ's shares were up just 5 cents, or 0.2%, at $25.46.
