Winners & Losers: Same-Store Sales

(Updated with ICSC data and stock.)

NEW YORK (TheStreet) -- While October same-store sales jumped 2.1%, in the strongest result for the metric since July 2008, there were still some unexpected winners and losers.

Out of the 28 companies tracked by TheStreet, 13 beat expectations while 12 missed forecasts.

Still, despite the big gain, retail shares were mixed, with the S&P Retail Index inching up just 1% to 385.56 in morning trading.

One of the biggest surprises was American Eagle Outfitter's(AEO) 5% same-store sales decline. Analysts were actually predicting a jump of 1.7%.

As a result, shares are plunging 12.8% to $15.57 in afternoon trading.

The teen retailer saw traffic slow toward the end of the month and offered fewer promotions than last year. Its men's category declined in the mid-single digit range, more than its women's category did.

American Eagle expects third-quarter earnings between 20 cents and 21 cents a share, slightly lower than the 22 cents Wall Street is forecasting.

Aeropostale(ARO) posted a 3% increase, significantly below analysts' forecast of a 13.8% surge.
