If you’re wondering when the miners are going to take off, this week’s chart offers a sodden dose of reality. Notice first that GDXJ is currently trading about where it was in 2013. Lows a few years later near $15 followed the cliff dive from 2011’s exhilarating precipice at 180. Who could have imagined that, 10 years later, mining shares would still be scuddling lazily along, tormenting investors more or less in proportion to the limit of their patience?  Yes, this ETF could take flight at any time, like a bat from hell. And it will — just not on our time. If there is anything to console us in the meantime, it is the ease with which this vehicle’s gratuitous swings can be traded. Now, for instance, you can stay short down to 38.32, or do covered writes until then, and then reverse your position when the target is reached. That would be 2.60 below the so-far retracement low off May’s 47.25 peak. Don’t sweat the details.
