$GDXJ has shown signs of accumulation since Q3 2014. See Excess Demand/Supply signals. It appears $GDXJ is getting ready to outperform $GDX Gold Miners etf (see chart shown below). $GC Gold futures also have shown accumulation. I am planning to leg in to the Juniors. To reduce risk I prefer to invest long in the Gold Miner etf's.
Just an interesting study using arcs and Fib retracements. Using BRK for an overall proxy for our markets to gain insights as to if we may be nearing a generational top. This chart suggests to me that we may be closer to some sort of top than we are to the beginning of a new secular bull market as some have suggested.
