But on the brighter side for retailers, last-minute shoppers may not have yet started their shopping last month. According to a recent ICSC and UBS survey, only 6% of consumers have completed their holiday shopping. ICSC predicts a December sales increase of 3.5% to 4%.

Department stores were the only sector that, with a 2% jump, performed better than its year-to-date average, which has been 1.8%. J.C. Penney led with a 12% rise, followed by Neiman Marcus' 8.4% jump. May Department Stores posted the largest decrease, falling 7.9%.

Apparel chains were mixed. American Eagle Outfitters continued its hot streak with a 24.3% gain, and United Retail Group also had a strong month, with an 11% jump. But Ann Taylor fell 8.3%, Limited Brands fell 5% and Gap Inc. dropped 4%.
