Burt Flickinger and Arun Sundaram break down Dollar Tree (DLTR) earnings. Arun points out that traffic fell even worse than last quarter, but notes average ticket growth is boosting comp sales. He attributes this to Dollar Tree's multi-price point strategy, calling out concerns about the “sustainability of these results.” Burt notes major pressures on Dollar Tree’s customer base that are not “fully baked in,” and calls this the “high water mark” for the company.
