That stock is out of control. From 294 to 720 in 2 years!? Those are some amazing gains, and begs the question, how much higher can it go? Do you feel it is an overvalued stock at this point? CMG dropped a bit and is currently at 703.89. The reason I posted this in the stock market education category is I am hoping someone with a little more knowledge can explain why some of the stocks explode like this. And how dangerous are they???
