Pay attention to the destocking rhythm [6]. - The supply of alumina continues to increase, resulting in a surplus situation. Although the cost support is relatively strong and the further decline of the futures price is limited, the surplus pattern is difficult to change, and there is currently little upward momentum [7][8]. - Aluminum alloy is in the consumption off - season, with its price following the aluminum price. The tight supply of scrap aluminum and primary aluminum supports the price, and cross - variety arbitrage opportunities may be affected by the activity of aluminum alloy [9].
