The Market Vectors Gold Miners ETF (NYSE:GDX) is trading higher today by 0.37 to $50.67. This popular gold mining ETF has made a strong higher since late July. Yesterday the GDX bounced sharply higher as fear hit the major market indexes. The GDX will have intra-day resistance around the $51.00 area. Should the GDX trade above that resistance point then the $51.50 area would be the next important resistance level.
