Chipotle shares fall after downgrade to sell
Mizuho downgrades Chipotle shares to underperform, encouraging clients to curb exposure until it’s clear chief executive Brian Niccol can replicate the success he had at Taco Bell. “After an 80 percent run since Niccol's appointment as CEO, we believe the stock currently prices in an aggressive recovery," analyst Jeremy Scott writes. Chipotle shares remain up more than 60 percent so far this year.
