Chipotle's (CMG 0.38%)stock hit a wall this week when rising-star value investor David Einhorn outlined his bearish stance on the company and announced he would short the shares. Shares of the fast-casual restaurant chain dipped more than 10% following Einhorn's remarks on Tuesday. Over the past three months, shares have tumbled more than 25%, a surprising pullback for a stock that's been on a tear since the beginning of 2009.

Einhorn's key remarks touched on rising input costs that plague the entire restaurant industry, as well as the results of a survey showing that customers were surprisingly receptive to Yum! Brands'(YUM 0.51%) revamped menu at its Taco Bell restaurants. In the following video, Isaac and Blake offer their take on the call and discuss reasons for optimism about Chipotle's management and skepticism about Einhorn's singular thesis on the company.
