Economists Dr. Copper and Dr. Zinc are bullish

An article in today's FT galvanized my attention. Zinc has hit a 3-year high of $2,415/ton and a production deficit is expected this year. Since zinc is widely-used in construction (galvanized rebar) and manufacturing, maybe this portents a stronger global economy. (If so, Zn may deserve a PhD. in economics, honoris causa.)

Meanwhile, Dr. Copper, which still pretty cheap at $2.964/lb, is approaching the $3/lb level and has been rising for four months.

Of course, investment in new Cu and Zn production has been weak for several years. Perhaps prices reflect supply weakness mostly.

Should we be more positive about the global economic outlook?
