When trading these things, it's best not to have too much capital into one, I like to spread out into a handful that I track, and of course the ETF.  These gold stocks are always prone to do a  financing after their stock has run up, I've seen this too many times in the past where you are in one of them with nice gains then BOOM, all off a sudden that stock does a financing because their stock ran up recently and your stock then gaps down 20% in the morning. 

anything just something to keep in mind, these stocks can be bad about that and as prices work higher some companies will take advantage of the move up in their stock to do this.  Generally it's with the smaller ones of course
