Are you sure your numbers are right? I'm talking closing prices, in the two year chart. I use closing prices when I want a longer term view /perspective. Intraday highs and lows don't count chief :)
My figures are below:
Date, Open, High, Low, Close, Volume
1-Feb-08 10.73 11.04 10.73 11.02 6,284,230
25-Feb-08 10.38 11.16 10.32 10.50 7,372,463
Have you thought about buying some Copper related puts?
