Iron ore price, page-29371

I did some research last night I think the reason fmg is being marked down is its lower grade product which makes it the most vulnerable of the big producers to having its discount for low grade ore grow. The air pollution issues in China are a particular concern as fmg is the most vulnerable to these concerns since its lower grade ore gives the biggest dust load of the major producers relative to the quantity of steel produced.
Short term fmg is protected from this by high demand for iron ore. Longer term the high grade product from iron bridge helps protect it also. But right now I think that is why it is being shorted and the very high dividend yield is due to concern at that risk.
