Specialty retailer Tween Brands has trimmed its fourth-quarter earnings forecast because of weaker-than-predicted sales over the Christmas period.

Tween Brands previously expected profit of 95 cents to US$1 per share for the quarterly period but now expects it to total 85-88 cents a share.

It also expects same-store sales for the quarter to be lower than previously forecast, with a predicted increase of 3% to 4% compared to the mid-single digits anticipated earlier.

The downgrade sent stock down 12%.
