According to foreign news, on January 9, Norwegian Hydro CEO Svein Richard Brandtzaeg told reporters on Wednesday that the company plans to restore its Brazilian alumina plant Alunorte to full production in "weeks or months." In 2019, the supply of overseas alumina increased, and the cost center of electrolytic aluminum moved further down. The Sino-US economic and trade measures have been concluded. The information revealed by the parties indicates that the Sino-US negotiations are getting better. The short-term non-ferrous sector will continue to rebound. At the cost end, the alumina price will stabilize in the short term, and the cost of electrolytic aluminum will remain stable in the short term. The weak consumption of aluminum downstream is a foregone conclusion; in terms of inventory, it is currently in the off-season of consumption, and the accumulated warehouse is expected to continue. The aluminum price is long-term, and the overall operation idea still suggests short selling, and the short-term rebound will provide short-selling opportunities.
