Loop Capital analyst Laura Champine says TJX kicked off its fiscal 2019 "on a high note" this morning with a "well-received" Q1 report. The company guided fiscal 2019 earnings per share to a slightly tighter range of $4.75 to $4.83, just above the analyst's estimate of $4.84. With consensus already at $4.84 and likely to move higher post-earnings, upside to guidance is already baked into the stock, Champine tells investors in a research note. Further, she expects margin pressures, including labor and transportation expenses, to become an "increasing drag on earnings power" as the year progresses. The analyst keeps a Hold rating on TJX with an $84 price target.
