Chipotle falls on comments

Greenlight Capital hedge fund manager and noted short-seller David Einhorn expressed concerns about Chipotle Mexican Grill's (CMG) prospects. At a conference he said he expects the upscale eatery to see more competition from a "resurgent" Yum Brands (YUM)-owned Taco Bell, due to its new upscale menu. Chipotle shares fell 4.2% to 302.96. Yum shares fell 1.4% to 66.45.
