(ICSC data and stock prices added.)NEW YORK ( TheStreet) -- Across the board, August was awash in red, with 21 out of the 28 retailers reporting same-store sales results on Thursday in negative territory. The International Council of Shopping Centers said total same-store sales slipped 2% for the month. But in each sector there were some clear winners and losers. Here's how TheStreet breaks it down. TEEN RETAILERS: Loser: Abercrombie & Fitch ( ANF) once again missed the mark, with August same-store sales plunging 29%, lower than the 23.9% tumble analyst expected. While the teen retailer significantly improved its merchandise selection for back-to-school and lowered some of its prices, shoppers are still hesitant to spend, and instead are trading down to wallet-friendly players like Aeropostale ( ARO). Shares of Abercrombie sank 4% to $30.82 in morning trading. Winner: Aeropostale once again was one of the biggest winners, jumping 9% during the month, more than the 7.1% forecast. Aeropostale raised its third-quarter outlook on better-than-expected results. The teen retailer now forecasts earnings in the range of 78 cents to 80 cents a share, up from a prior guidance of 76 cents to 78 cents a share. The news sent shares climing 6% to $40.96 in morning trading.
DISCOUNTERS: Winner: Off-pricers have been able to use the recession in their favor. Ross Stores ( ROST) reported a 6% incline in August, far better than the 4.3% jump Wall Street expected. Looking ahead the company forecast same-store sales gains of 6% to 7% for September and 5% to 6% for October. Loser: While BJ's Wholesale ( BJ) managed to beat Wall Street's forecast, falling 6%, less than the 8% decline expected, the company is still struggling due to lower prices at the pump. These declines outweighed gains in food, air conditioners, candy, cigarettes, computer equipment and housewares. SPECIALTY RETAILERS: Winner: Gap ( GPS) is making a comeback. Granted, it still saw a 3% decline in same-store sales during the month, but it beat the 7% drop expected by analysts. The specialty retailer has been slowly making its way back into the game with the re-launch of its 1969 denim line, beefed up marketing and refocusing its Old Navy brand. Gap shares rose nearly 7% to $21.01. Loser: Children's Place ( PLCE) struggled in August, with same-store sales slipping 8%, a much larger decline than the 3.3% fall expected. As a result, shares of the company were down about 3% to $27.66 in morning trading. -- Reported by Jeanine Poggi in New York Follow TheStreet.com on Twitter and become a fan on Facebook.
