With recession fears, housing market worries and credit concerns, retailers have been facing tough times, especially during the holiday winter season of December and January when sales came with weak numbers. But on the heels of these disappointing results, retailers got a beam of hope as February's sales numbers showed a surprising increase.

Encouraging news for retailers showing a rebound in consumer spending during the past month came after world's largest retailer Wal-Mart Stores Inc. (NYSE: WMT) announced a rise of 2.6% for its February same-store sales. The company said that its same-store sales during the period were helped by strong gains from gas, food and flat-panel TVs. Analysts were expecting the retailer show an increase of 1.1% for its same-store sales, according to Thomson Financial.

Among other retailers that showed a rebound in February sales were Costco Wholesale Corp. (NASDAQ: COST) and Saks Inc. (NYSE: SKS), both of which reported stronger-than-expected gains. Apparel retailers Pacific Sunwear of California Inc. (NASDAQ: PSUN) also reported earnings results exceeding estimates of 6% sales growth last month.

For Limited Brands Inc. (NYSE: LTD), though, February didn't come with positive results. The company stated that higher energy and food prices put pressure on consumers who focused on necessities.
