In the long run this correction is a good thing. It flushes all the week hands so the next run up will be that much stronger. Analyst are forecasting a $10 distribution next year putting the current yield at 13%. More new wells are be fracked every year and existing wells will need to be refracked after they peter out. There is no end in sight for sand demand.
Don't forget this is nothing more than an commodity. At first there's a shortage, price goes up, producers open new mines, eventually supply meets demand. rest is history. Question will demand keep outstripping supply.
