The volatility in the stock is related to high volume trading and reflects the current battle ground of the lower earnings comp expectations over the next 3 quarters vs looking forward coupled with conditions of the current sector macroeconomics. If you can figure out the new price ranges it will become a  great profit generator.

However, as time expires I believe the stock will have a bullish bias as it is kind of difficult to screw up a 4% Cu open pit copper mine.
