In an early indication of shutdown-related trouble for October, ICSC-Goldman's same-store sales tally fell a sharp 0.7 percent in the October 12 week with the year-on-year rate falling to plus 1.0 percent which is the lowest rate of the recovery. The 4-week average for the year-on-year rate, at plus 1.6 percent, is also at a recovery low. The report cites the government shutdown as a key factor that is weakening sales across components. Redbook, which reported slowing sales in the prior week, will be posted at 8:55 a.m. ET.
