Report Summary 1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints - In September, the resumption of alumina production will increase, and warehouse receipts will gradually accumulate, further strengthening the expectation of oversupply. Due to the rainy season in Guinea and the domestic parade period, there are strong disturbance factors on the ore side. Alumina should be mainly shorted on rallies, but chasing the decline is not recommended. - Before the "Golden September" peak season, the stocking speed of downstream sectors has started quickly. There is a possibility of exceeding expectations in the demand for electrolytic aluminum during the peak - season cycle, and the profits of the aluminum industry will continue to shift from the upstream to the downstream. Driven by the Fed's interest - rate cut in September and the domestic peak season, electrolytic aluminum has strong upward momentum. - Due to the peak - season mismatch of aluminum alloy, there is room for the spread of far - month contracts to continue to repair. Opportunities such as the widening of the AL2510 - AO2510 spread and the narrowing of the AL2511 - AD2511 spread can be tracked. Attention should be paid to the pace of the US interest - rate cut and the confirmation or falsification of strong demand. [3] 3.
