Greenfields exploration is just that - it's high risk with the possibility of high rewards. But this stock was grossly overpromoted and the information upon which an investor had to rely was woefully inadequate. The main documentation that many investors appeared to be relying on for information was an analysis by the same company that did the CR!
The list of PRA's sins is long and the selling off of a sh!tload of options in the last couple of weeks smells strongly.
If holders of this stock decide to go for the class action, I wish them the best of luck.
