Shares of Chipotle Mexican Grill (NYSE: CMG) hit a 52-week (and all-time) high recently. Let's look at how it got here and whether clear skies are ahead.

How it got here
This longtime Rule Breaker keeps marching higher, rain or shine. Shares almost never pull back in any meaningful way, but if they ever did, fellow Fool Alyce Lomax would pounce all over it in a heartbeat, since it's on her watchlist (add it to yours, too, by clicking here).

A couple months ago, the burrito roller put up a strong fourth quarter to close out its full-year 2011. Chipotle opened 67 new restaurants in the quarter, bringing its total to 1,230. European expansion is just now beginning, with last year seeing the first two locations in the region.

The company's focus on "Food With Integrity" has led to incredibly strong brand loyalty, which helps it pass on rising commodity costs to regular diners who are willing to pay up to chow down. There are plenty of regulars, too, with comparable store sales growth accelerating over the years.

Chipotle got here simply because its business is rock-solid and just keeps on growing.

Chipotle's lofty valuation looks rather justified, considering its far-superior profit growth over the past five years. In addition, one major reason why Yum!'s return on equity is so much higher is because it's working with a smaller equity base and utilizes more leverage than Chipotle. Yum! has a debt-to-equity ratio of 3.6 compared to Chipotle's 0.36 -- 10 times more leverage.

The company looks much better than Jack in the Box, owner of direct competitor Qdoba Mexican Grill, and boasts much higher quality food than Yum!'s Taco Bell Mexican eatery.

What's next
Chipotle has a lot going for it, so long as you can stomach its premium valuations along with its burrito bowls. Considering the boundless international growth opportunities and incredible business momentum it has, I think Chipotle is cleared for take-off.
