Everything appears to be going right for Gap, Inc. (GPS) as it has become the darling retailer of Wall Street. Left for dead during the Great Recession, shares of this Zacks Rank #1 (Strong Buy) are at 10-year highs as monthly comps continue to come in stronger than expected.Gap is a famous American retailer with three main brands: Gap, Old Navy and Banana Republic. It also operates Athleta, the women's athletic and yoga retailer which is a big part of its strategy to expand into the lucrative athletic wear market. It has over 3100 company operated stores and 300 franchise stores. Each brand also has its own web site.Another Strong Month in JuneGap is one of the few retailers which still reports monthly sales results. On July 11, it reported June results which were better than the analysts had expected, with same store sales jumping 7% compared to flat sales the year before.Other retailers' results weren't as strong as many blamed the cooler than expected weather. Old Navy, its largest segment, led the quarter as sales rose 13% due to summer promotions and strength in flip flops and dresses. Gap also showed strength as its sales rose 5% due to strong sales in denim and shorts. Only Banana Republic struggled, as global sales fell 1% due to softness in the women's side of the business. Athleta is not yet big enough to be broken out separately.
