Dollar Stores : The dollar stores Dollar General ( NYSE: DG ) and Dollar Tree ( NASDAQ: DLTR ) both reported solid high-single-digit growth versus last year but there is a clear difference here as well. While the group is set up well for the economic environment Dollar Tree is struggling versus its competitor and provided a softer outlook for the second half of the year. The mitigating factor is that Dollar Tree is reinvesting in growth and profitability so it should do well over the long term. In the near term, Dollar General not only bought back shares and paid a dividend but it increased the buyback authorization while Dollar Tree did none of those things. Membership Outlets: Membership outlets came into the spotlight with Walmart's results and Sam's Club segment is what may set it apart from Target this year. Sam's Club led Walmart's growth and is underpinning the outlook with a roughly 10% increase in membership and membership at record highs.
