Something worth considering is that most SOP production is not in the US, so as the USD continues to weaken against all currencies this will hit the profitability of most producers. High cost ones may cut back supply or stop. The Mannheim Process is expensive, they'll get hit. Supply cuts with constant demand will drive the price up. This is all speculation of course, but you have to take a wider view when it comes to commodities, not just focus on one company and one currency. Just part of the commodity investing game. As long as KLL has a nice margin between it and the Mannheim Process producers, it'll do fine.
