I bought shares of American Eagle Outfitters (NYSE: AEO) back in June because I admired the apparel retailer’s standout comps growth in a low-growth industry, the surging sales of its Aerie lingerie and activewear brand, along with its e-commerce strength, rising margins, and low valuations. The stock slipped after its second quarter earnings beat didn’t dazzle investors, but I added more shares on that dip.
