Dollar Tree (DLTR) has $1B in cash, something that Ed Butowsky says will keep the stock in a "growth mode" as it eyes expansion into old CVS Health (CVS) storefronts. He believes the tariff impact is hard to assess as even the discount retail companies themselves don't know how to give guidance. For Dollar General (DG) and Five Below (FIVE), he's less enamored with the business models versus Dollar Tree.
