The latest COT confirms short covering by the cartel. Last week alone they covered 3,780 contracts, or 6% of their total short positions. Total open interest in silver declined by 387 to 100,165 contracts. Apparently people are giving up on the (more broken than usual) paper markets. I don't really blame them, either. AGQ/SLV have become completely untradeable.
As has been pointed out many times now, this is putting a great deal of stress on the spot market, as well.
