Ann: US$300m Finance Facility and Management changes, page-413

I think what matters here is whether or not you are here for the long haul or a quick trade.
The fundamentals are good. The future looks promising.
If you are in for the long road, try to focus less on the day-to-day movements. As others have mentioned, it's a trader's game at the moment. Those looking to accumulate large numbers or only thrilled to see this type of price action.

I know it's hard. I myself have twitchy fingers from watching my holding go up and down thousands in two days. But I know I am here until production or some fundamental change that makes me pack up and leave (I don't expect the second option).

Whether you are in for the long or short road, it is a good idea to have goals. Or you will go crazy obsessing over details that might be irrelevant to the kind of holder you are.
Sometimes the market just does what it does, and sometimes there is no explanation.
