From Bill Bonner’s Diary (USA) – Gold is up 20% so far in 2016. Over the same period, the MarketVectors Gold Miners ETF (GDX), which tracks the major players in the precious metals mining industry, is up 71%. And the gains have been even bigger for MarketVectors Junior Gold Miners ETF (GDXJ). This tracks a group of “junior” mining firms. These have a smaller market cap than the companies tracked by GDX and tend to have less proven gold in the ground. So far this year, GDXJ is up 81%.
