Copper Short. Copper has been operating in a relatively narrow trading zone since mid-January. Looking at the history of the period and the copper graph, it could happen that the copper bounces off the upper resistance and then falls back to the level of the support line. As far as the fundamentals are concerned, at first glance, much of the price movements in the markets reflects a “desire” for the recovery of global economies. However, a closer look shows that some markets directly related to the health of the economy do not have the drive and strength for more significant growth. Copper is exactly one of them.
