I think the miners will take whatever direction gold does. If gold is going up, so are the miners. Gold down, miners the same. Miners may look technically healthy but if gold starts to fall the miners follow pretty much without fail and they fall faster and harder. We don't have real markets populated by flesh and blood any more. It is all computer algorithms and when the order comes in to sell gold, the miners get sold off as well. With the premarket rubbish (GDXJ was down yesterday 1.2% on 50,000 shares traded) I would say the best thing to do would be make sure you have a solid trend in gold itself before considering a position in the miners. Just my opinion but I can't see any other way.
That is currently what I am doing anyway, I am watching for an upward turn in gold and once I have that I will take a closer look at the miners.
