Chipotle shares are muy caliente.
The burrito chain's stock surged nearly 13% in after-hours trading Thursday following fourth-quarter results showing the company's strong growth continuing.
Chipotle ( posted $844 million in sales, up 21% versus a year prior, and $80 million in earnings. The company is expanding aggressively, opening 56 new restaurants in the fourth quarter, and now has nearly 1,600 locations. )
Chipotle was spun off from McDonald's ( in 2006, and shares have been on a tear ever since, rising over 60% in the past year alone. )
McDonald's meanwhile may be losing its luster. Its stock has been in the doldrums as it's struggled to match new menu offerings from competitors like Burger King ( and )Wendy's (. )
There are still some Chipotle skeptics out there -- hedge fund moguls David Einhorn and Jeffrey Gundlach have made cases against the stock in the past year and a half.
