Giving that fact that the comodity prices have been rising quite a lot recently, CMG might miss the earning estimates this quarter and I wouldn't be surprised if they warn. If they do, we can easily see a 15% drop in the stock. It's way too overpriced!!!
The commodity price rise you speak of, has already been factored into Chipotle's stock price. The large institutions look to be accumulating shares going into another robust earnings report. Just sit back and enjoy the ride. Go Long, Stay Strong!
