The jury is still out on whether the 8 million purchase at 16:10:00 on Friday June 17th was related to the Van Eck Fund adjusting to the change in the GDXJ Index, or a significant hedge fund short cover. Since there was a similar pattern of trading by "Shitty-Corp" in GPR, another Index-adjusted position, to the tune of 3.85 million shares at the exact same time (16:10:00), it probably is a pre-arranged position buying cross by Van Eck.

Personally, I hope it is related to the Index adjustment because it just adds another concern for the naked-short hedge fund(s) and the culprit's short position remains intact, vulnerable to the upcoming fireworks!
