The aggressive shorts have always been able to derail a rally and actually push the price lower forcing panic sells by some CPRK stock holders/flippers.
This time....it may be they are caught in between a rock and a hard place. We will know in a couple of hours.
My guess is the short volume is still in the 40% range.
EDIT: Significant break up at end of day with over 20% of volume could push the short action below 30% because they capitulate.
