ICSC and Goldman Sachs Weekly Chain Store Sales Index: Weekly retail sales slipped by 1.3% for the week ending May 17

NEW YORK, 2014-5-23 — /EPR Retail News/ — Mother Nature once again kept the chill on retail sales as rain and snow left consumers soggy and constrained their ability to shop this past week. As a result weekly retail sales slipped by 1.3% for the week ending May 17, according to the International Council of Shopping Centers (ICSC) and Goldman Sachs Weekly Chain Store Sales Index. On a year-over-year basis sales remained positive but slowed to 2.4% for the week.

“This past week’s slippage was mainly due to Mother Nature as a very slow moving storm left heavy snow in the Rockies and flooding in the East,” said Michael Niemira, ICSC vice president of research and chief economist. “Weather Trends International (WTI) reported that ‘It was the coldest second week of a retail May in four years and the wettest in more than 23 years.’ But despite the weather, business at more retail segments were positive than negative relative to the same week in the prior year—which is an encouraging sign,” Niemira added.

For May, ICSC research forecasts that monthly comparable-store sales will increase by 3.0% to 3.5%. Please note that next week’s report will be released on Wednesday, May 28, 2014.

The Weekly Chain Store Sales Snapshot is produced by the International Council of Shopping Centers and Goldman Sachs. This index measures U.S. nominal same-store or comparable-store sales excluding restaurant and vehicle demand. The weekly index is constructed as a sales-weighted geometric average growth rate to preserve long-term consistency and is statistically benchmarked to a broad-based monthly retail industry sales aggregate that currently represents a sampling of leading retail chain stores, which also is compiled by ICSC. A representative sample of those major retailers has been used as a control group to extrapolate the weekly sales index. As such, the weekly index statistically represents industry sales and is not just a sum of sales for a handful of retailers. The standard period used for the index is Sunday through Saturday, even though some retailers use a different weekly accounting period. The weekly sales index is presented on an adjusted basis to account for normal seasonality and to counter other data anomalies. Weekly seasonal adjustment is at best difficult for chain store sales given that retailers can and often do shift promotions to counter typical shifts in the calendar. Nonetheless, the approach to weekly seasonal adjustment used follows from the Piser Method, which was popular in the early 1930s and became the standard for weekly adjustment.
