I have seen what is happening with SLW. You might be right, but on the other hand we will never feel sure that the bottom is in. So even if SLW were to go to $28 or lower, we would still think that it might go even lower than that. JPMorgan can also reduce its net short position and turn to a net long position in an increasing silver price trend. They might be net long by the time silver reaches $35.
By the way, AUMN is pretty strong today. The shorts must know that there is little time left before gold and silver will take the miners strongly up.
