It really seems to be flying around wildly relative to the price of gold. Certainly not another shelf offering. Could be some funny pair trade going on. Alternatively, could be some recent (or not so recent) buyers who are bailing because of the shelf offering. I do think that there might be a growing irritation that the shelf offerings are non-accretive and unappreciated when they show up.
And speaking of odd, silver has covered a $2 range today. Six Flag behavior.
