氧化铝周报：宏观情绪改善，期价止跌震荡-20251025

1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - The price of alumina futures stopped falling and fluctuated due to the easing of Sino - US relations and the expectation of the Fed's loose monetary policy. The spot price continued to decline under the pressure of continuous inventory accumulation. Although the alumina smelting capacity surplus pattern is difficult to change in the short term, the expectation of the Fed's loose monetary policy and the approaching of the current price to most manufacturers' cost - lines may lead to an increase in production cut expectations. It is recommended to wait and see in the short term. The reference operating range of the domestic main contract AO2601 is 2700 - 3000 yuan/ton, and attention should be paid to supply - side policies, Guinea's ore policies, and the Fed's monetary policy [11][12][13]. 3.
