Copper

For a long time, copper is best indicator of economic activity.  It is still the best metal for electricity transmission and used in electrical appliances and home wiring.

Nothing seems to be changing yet suddenly copper is in demand with possible shortage soon!  Is this a marketing fake news or is something is happening in China which escalated the demand for it?

While I have sold a lot of mining stocks (mostly educated speculative ones), I did retain those that are producing or going to produce soon.  SFR is still in positive territory while AVB is advancing crazily.  Then there are the giants like BHP and RIO.
