copper will only rise sharply if the trade war between the US  and China is over.  the expectation is that this trade war will certainly continue until the end of the year.  More and more economists are predicting a severe recession that is now showing its first symptoms and will become more powerful in 2020.  So when the trade war is over, copper prices can be depressed again by the upcoming recession.  I do hope that CF will sell its share in SC for the next economic recession, otherwise we can wait much longer.  In addition, I do not agree with you that the price of the CF share rises with a rising copper price.  CF has no copper mines in production.  We, as shareholders, only get added value in the event of the sale of one of the copper mines.
