I looked again at the XGD canadian gold co etf, and its chart movements in terms of ups and downs, and cash flows ~ it is very similar to SGR in timing, so SGR isn't that odd. I agree with your post and hope you feel like sticking with em beyond May, albeit paying attention to trading your position a little. The charts do seem to confirm SGR is, in terms of volatility, somewhere between a junior speculative investment, and a large producer, so we shouldn't be taken too much by surprise.
