MINNEAPOLIS (Stockpickr) -- Congratulations to those who sold short Aeropostale (ARO) in advance of the company's disappointing earnings report. In that report, the company announced the resignation of its CEO amid a quarter whose results failed to meet expectations.In addition, guidance for the future was weaker than expected. Shares dropped precipitously, closing down more than 12% the next trading day. The news pretty much confirmed my expectation that the company was lagging fellow teen retailers Zumiez ( ZUMZ) and Hot Topic ( HOTT). My second pick for the week was Trina Solar ( TSL). There the expectation was for a big pop of the stock on the heels of an upside earnings surprise. Well, we got the upside earnings surprise, but the market reaction was not what was expected. >>Also: Cramer's Retail Stocking Stuffers In fact, traders long the stock would have been wise to sell with a small loss as the trade went from bad to worse throughout the day. It is hard to explain the harsh reaction Trina's news, especially with oil prices moving higher last week. Chalk it up to the whims of the market. That happens from time to time, and the best protection is to exit a trade when it goes against you. If you are playing along at home, make your bets and be ready to cash out or cash in accordingly. This week we have an interesting selection of companies releasing earnings. Last week I mentioned Smith & Wesson ( SWHC). The company moved its earnings release to the forthcoming week. I would trade the stock expecting a disappointing report. Here are three other names to trade next week: Casey's General Stores ( CASY - Get Report) Casey's General Stores operates gas stations and convenience stores across the country. The stock has been on fire this year, gaining some 30% in value. Will the trend continue with this week's earnings report? Convenience store sales at higher profit margins have been propelling earnings growth during the recession. Consumers looking for convenience agree to pay a bit more in order to avoid extra trips to the grocery store. >>Also: Top-Rated Food and Staples Stocks
