RE:RE:Copper at a 21-Week High...No one can see the future. But we can see the past and we can extrapolate. January 15, 2016 copper closed at $1.95 per pound. Friday, July 21, 2017 copper closed at $2.71 per pound - a 39% increase over 20 months. An increase of 10.7% over Friday's close would bring copper to $3.00 per pound. Why is this inconceivable?
