Since bull market correction low Dec 23 2016, GLD+ 12% CDX+ 20% GDXJ+ 13%. I rarely buy ETFs, because you can’t trust they will do what they are supposed to do, long term. Short term ok. For example I doubt GDX is supposed to out perform GDXJ like the chart shows.
Play here. Add your favorites to the mix. Use year end 2015 and year end 2016 for reference lows.
