AutoZone (AZO) is back in focus after the company lifted its share repurchase authorization to US$35.25b and reported third quarter earnings and net sales that topped estimates, supported by domestic commercial momentum.

At a share price of US$3,128.70, AutoZone has seen short term momentum pick up with a 1 month share price return of 3.34%. However, the share price is still down 5.30% year to date and the 1 year total shareholder return is down 13.32%, while the 5 year total shareholder return of 101.92% points to stronger long term compounding.
