Retailers are announcing September U.S. same-store sales figures Thursday morning, and research firm Retail Metrics has noted a modest year-over-year gain of 0.7% for the month.

Retail Metrics had projected that overall sales would be down 0.2% year over year for the month. In August, retail same-store sales slipped 0.6%.

The number of retailers reporting same-store sales has declined significantly over the past several years, but the reported numbers do provide a kind of interim report on quarterly performance at the country’s retail stores.

A late Labor Day weekend and some last-minute back-to-school shopping helped to offset the negative effects of unseasonably warm weather and small wage gains in the month.

Here are results from the stores we track:

Buckle Inc. (NYSE: BKE) reported that same-store sales for September fell 6.7% compared with the same month a year ago. The Retail Metrics estimate called for sales to drop 2.57%. Net sales for all stores fell 5.6% and totaled $97.4 million for the month.

Buckle’s shares traded down 4.8% Thursday morning to $36.45, after closing Wednesday at $38.28, in a 52-week range of $36.01 to $56.13.

Stein Mart Inc. (NASDAQ: SMRT) reported a 2.8% decrease in same-store sales for September, well above the 0.7% decline estimated by Retail Metrics. Total sales for the month came in at $117.3 million, down 1.8% from a year ago. The company noted that September sales were negatively affected by unseasonably warm weather, one less week of post-Labor Day fall fashion selling and a shift of promotional events.
