price fall

BKN made over 37% of its sales to the iron ore sector in the 2011-12 financial year. The percentage rises if you add coal. Both iron ore and coal mining companies are taking big price hits right now, so their spending on BKN products is likely to fall too.
For relevant data in the company presentation on its latest results. So the price fall is understandable. It is now a very risky stock along with all contractors exposed to the iron ore and coal sectors . The Annual Meeting speeches will be important for forward guidance. I am not hopeful. They will have to cut capex.
