It was unsustainable because of a number of factors from both the production and demand sides, trying to meet an expected rise in end user demand that did not eventuate. The whole market was unbalanced. It was a learning curve for me, and taught me a bit more on how to research and look more closely at market forces. I bought in initially in early 2011 for the same reasons I still hold, but failed to pick up the reasons for the fall post purchase. The fundamental reasons I bought are still valid and are starting to eventuate, but have taken much longer than I had anticipated. The upside is I now have nice low average due to low price purchases and anticipate a much higher return. Looking forward to the next 12 months or so as I think by the end of next year I will have a huge smile on my dial, and it will be perfect timing for me.
