AMEX:GDX VANECK VECTORS GOLD MINERS ETF
GDX was on fire recently and apparently this kind of vertical move is not sustainable. I marked the possible consolidating area in orange (it should and healthy). Because of the strong trend the pullback may or may not happen. Any pullback or continued breakout is a buying opportunity IMO, and chance is good it will challenge the red ($38 ~ $42) sooner or later.
