Thanks in large part to the natural gas boom, CRR is up over 328% off of the 2009 lows.
However, how long it can maintain its status as a high-flier is another matter entirely.
In fact, I expect that CARBO's entire business model is about to come under attack, which is why now is a good time to sell.
CARBO is one of the world's biggest suppliers of proppant. It's one of the key ingredients in the shale oil and gas boom that is turning places like Williston, ND, into boomtowns.
