UPDATE: Longbow Upgrades Chipotle, Optimistic On SSS & Price Increase

In a report published Wednesday, Longbow Research analyst Alton Stump upgraded Chipotle Mexican Grill (NYSE: CMG) from Neutral to Buy and set a $641.00 price target.Stump noted the acceleration in Chipotle's same-store traffic over the past four quarters year-over-year. Same-store traffic also grew over the last two quarters on a two-year stacked basis.Alton Stump commented, “This feat was particularly remarkable amidst a challenging industry demand environment along with harsh weather conditions during late 2013/early 2014. While various competitive threats pop up occasionally for CMG, the company's superior performance versus its peers is showing no signs of slowing down.”Longbow added that the four to five percent price increase will have little to no impact on store traffic.
