Retailers reported dismal December same-store sales reports after one of the worst holiday seasons in decades, but some teen retailers managed to escape the gloom with positive results.
Overall, same-store sales fell 0.9%, according to Thomson Reuters, the second-worst showing since the company began collecting sales figures in 2000. Same-store sales, or sales in stores open at least one year, are considered a key gauge of a retailers performance because they measure sales at existing stores rather than newly opened ones.
Aeropostale (ARO - Get Report) was one of the best performers, as same-store sales rose 12%, ahead of the 4.2% decline analysts polled by Thomson Reuters expected. The company raised guidance and a Brean, Murray Carret & Co. analyst upgraded the stock to "Hold" from "Sell." Shares rose 71 cents to $20.44 for the day.
