For Abercrombie and Fitch ( ANF), the losing streak continues. The apparel retailer on Thursday announced that sales at stores open more than a year declined a whopping 13% in November. The performance marked Abercrombie's 8th straight month of slumping same-store sales and the 18th in the last 19 months. A late Thanksgiving was the retailer's explanation, although the company's refusal to discount heavily was a more likely cause. The consensus among Wall Street analysts was that Abercrombie's comparable store sales would decline 8.8% in November, noted Emme Kozloff, an analyst with Bernstein. "That's an order of magnitude higher than I expected," Kozloff said of the 13% number. Bernstein does not have any investment banking relationships with Abercrombie. Like other retailers who struggled in November, Abercrombie blamed the slump in part on Thanksgiving coming later than normal this year. That got the holiday shopping season off to a late start, with fewer post-Thanksgiving shopping days falling in November. "This change in the calendar should benefit December somewhat," said Seth Johnson, the company's chief operating officer, in a conference call. But he added, "It's difficult to predict what impact the calendar shift will have on our overall holiday business." Other apparel retailers also experienced tough times in November. Ann Taylor Stores, for instance, posted a same-store sales decline of 10.3% compared with November 2001. Comparable-store sales also fell at Bebe Stores ( BEBE) and American Eagle Outfitters ( AEOS) by 15% and 4.9%, respectively. But the story wasn't all negative for apparel retailers. Apparel specialty stores tracked by Instinet Research posted same-store sales gains of 1.1% in November compared with the same time last year, the firm said in its Redbook same-store sales report. Among the banner performers were Gap ( GPS), Chico's and Pacific Sunwear, which increased their same-store sales 9%, 11.3% and 11.7%, respectively. But not all of Abercrombie's problems had to do with the late Thanksgiving.
