Chipotle's (NYSE:CMG) stock price has been under pressure lately. Hedge fund manager David Einhorn contends not only that Yum! Brands' (NYSE:YUM) new Taco Bell menu poses a threat, but also that the burrito king is overvalued. Indeed, the company has underperformed the likes of Wendy's (NASDAQ:WEN), McDonald's (NYSE:MCD), and Whole Foods (NASDAQ:WFM) while carrying a higher valuation.

Chipotle's growth prospects may be brightening, however. The company's sole ShopHouse location has done well enough that management is opening two more of the Asian restaurants.
