Your post is full of all kinds of misinformation. PSN didn't have a cloud of doubt. It not only met quarterly expectations, it handily exceeded them for several years. Analysts gave it very high projections. When those exceptionally high projections were not met the price dropped dramatically. PSN gave decent projections on what the new expectations should be. By then it had cratered. Wall Street sells first then asks questions later.
As far as all the shale oil sweet spots being tapped already, what a load of cr*p. You don't have a clue.
