Deutsche Bank analyst Karen Short recommends using the post-earnings pullback in shares of Starbucks as a buying opportunity. The selloff is related to more modest international same-store-sales and lower than consensus Q2 guidance, but expectations were very high, Short tells investors in a post-earnings research note. Starbucks continues to generate best-in-class same-store-sales across the Americas, the analyst contends. She reiterates a Buy rating on the stock with a $70 price target. Shares of the coffee giant are down $1.79 to $57.24 in pre-market trading.
