Tight supply is expected to strengthen copper prices into a long-term bull market? Against the backdrop of rising inflation expectations and rising global commodity prices, the performance of domestic listed companies in the copper industry rose across the board in the first quarter of this year. Statistics from Star Mine of the Financial Associated Press show that the 12 listed companies in the copper industry in which A shares have issued quarterly reports have all increased significantly, with an average net profit increase of 288% compared with the same period last year. Industry analysts generally believe that in the short term, under the background that it is difficult to increase the supply of international copper mines disturbed by the epidemic and the rapid growth of copper demand driven by the new energy industry, the rise of copper prices has been strongly supported.
