"Dr Copper"

Copper rallied 225 points from Dec 26 2009 to 7 Jan 2010,pretty well "squaring"
a one year cycle at a ratio of 0.618 (365x0.618=225) and has broken a well established trendline.Copper is regarded as the most economically sensitive commodity,and has been attributed a PhD in economics for its forecasting ability,hence the name sometimes attributed to it !A trend change could therefore be signalling slower growth ahead.
