H&M, whose biggest rival is Zara owner Inditex (ITX.MC), said September sales would be down 10% year-on-year measured in local currencies.
That compares with Inditex reporting sales between Aug. 1 and Sept. 11 that were up 14%.
Operating profit in the Swedish group's third quarter jumped to 4.74 billion crowns ($431 million) from a year-earlier 902 million.
The year-ago figure included a one-off cost of 2.1 billion crowns for the group's exit from Russia, which also accounted for four percentage points of the 10% September sales decline.
H&M announced a share buyback programme starting on Wednesday, planning to buy back up to 3 billion crowns of stock by March 31 next year.
