Aeropostale (ARO) sees excellent growth in Q2 -- could it last?

Aeropostale (NYSE: ARO), a retailer whose colleagues include Abercrombie & Fitch (NYSE: ANF), Pacific Sunwear of California (NASDAQ: PSUN) and Gap (NYSE: GPS), issued its Q2 report on Thursday. The stock didn't do much after the numbers were made public despite reporting a very nice 21% increase in sales during Q2, and a whopping 63% jump in earnings per diluted share to 31 cents. Why such a blasé reaction? Well, the retailer was only able to match the expectations of Wall Street analysts, so that might offer some justification for the lack of a decisive bid.

I felt the same way after reading Aeropostale's earnings release as I did after perusing the stats behind GameStop's (NYSE: GME) recent quarter, thinking the company deserved at least a little excitement, especially when one considers that last year at this time, the mall chain saw a 4% contraction in same-store sales. Of course, there is one understandable difference between the GameStop situation and the Aeropostale scenario. GameStop's stock wasn't trading near a 52-week high, and Aeropostale's shares are. So, perhaps the market is perceiving that a lot of the good news is already priced in.

Aeropostale has done well this year. Its stock is up over 28%. Should that concern potential investors? Perhaps. After all, this is a mall retailer based on fashion and investors must consider that Aeropostale's current hot streak could cool. If that happens, the stock might end up retreating back to the lower end of its 52-week range. While there are any signs that such a retreat will happen, I only want to throw into the discussion the concept of fickleness among the youth.

If you really like Aeropostale and want to buy its stock, it might not be so bad to wait for a better price, in my opinion, to allow at least a little margin for error.
