(Update adds same-store sales chart, ICSC data and stock prices.)It was a mess of a month (or, should we say, a miss of a month) for retailers, with at least a dozen of the retailers reporting June same-store sales on Thursday missing expectations. Overall June same-store sales tumbled 5.1%, according to the International Council of Shopping Centers. The group expected a decline of 4.5%. Wet weather through most of the month contributed to the soggy results, but on the whole it appears that June reiterated what we already know: consumers are still not spending.
