JPMorgan analyst Christopher Horvers views the 10% post-earnings pullback yesterday in shares of AutoZone as "way overdone." He recommends using the selloff as a buying opportunity. The analyst lowered his price target for the shares to $900 from $920 and keeps an Overweight rating on the name. Horvers says that at the end of the day, his fiscal 2019 forecast declined 1.6% as a result of incremental investments of tax benefits, partly offset by more share repurchases given the stock decline. Further, the analyst believes AutoZone comped flat in the first half of Q2 and up 4%-5% in the back half.
