Here we go, perfect example just like the GG case. In fact you can go through most of the big mining stocks and the small ones too and see this pattern of high volume selling in order to push the price back down. If these were stocks that the street wants to have go up, they would have moved another 5% higher. This should have been a 10% up day for many of these stocks but it was capped at the biggest option strike nearby. In this case there are 8,000 calls at 55.00.
