Can anyone explain the recent huge jump in high grade copper??

Hi,

I found the following:
"declining ore grades in mines, infrastructure problems and postponing planned mine projects due to problems with project financing,”

One approach to trading is to look at fundamental issues, for a commodity this involves building an in depth understanding of supply and demand issues. Another approach is to use technical analysis. At its most extreme technical analysis would suggest that all fundamental issues are reflected in price action, and that the study of price action alone is sufficient for making trading decisions. If you subscribe to that view, then while you might have a view on what is causing the price action (from a general interest perspective) you dont actually need to know to make trading decisions.
