UBS analyst Michael Lasser said the Advance Auto Parts Q1 results were a reminder the company's turnaround is going to have bumps along the way. The analyst said the company's comp decline was not as bad as feared and said there was an acceleration in comps from Q4 to Q1 that shows its investments in its customer base, availability, and execution are resonating. He believes the company is laying the ground work for long-term improvement and the story remains attractive. Lasser maintained his Buy rating and lowered his price target to $170 from $160 on Advance Auto Parts shares.
