Report Industry Investment Rating No information provided. Core Viewpoints of the Report - The price of alumina will remain under pressure, but the support from the cost line is gradually emerging, and the room for further decline may be limited. In the short term, the alumina futures price may fluctuate at a low level. - The price of electrolytic aluminum has the characteristic of being "easy to rise and hard to fall" in the medium and long term. In November, whether the aluminum price can continue to rise depends on the sustainability of inventory reduction and the acceptance of high aluminum prices by downstream users. A strategy of buying on dips is recommended. - The price of ADC12 is expected to maintain a relatively strong oscillation in the short term, and attention should be paid to the raw material supply situation and the rhythm of demand recovery. [6] Summary by Relevant Catalogs 1. Market Outlook - Alumina: The short - term marginal supply of domestic bauxite is tightening, but there is supplementation from imported ores, and the supply is not significantly tight. The price of imported ores is slightly weak. The operating capacity of alumina is at a high level, but the release of new capacity still takes time. Some alumina enterprises in Shanxi, Henan, and Guizhou are close to the break - even point or in a loss state. Considering the possible impact of the heating season in November, attention should be paid to changes in the supply side. - Electrolytic aluminum: The expectation of loose liquidity will be the theme of the macro - market in November. The Fed cut interest rates in October, but a second rate cut in December is "far from a foregone conclusion". After the resolution of the US government shutdown, attention should be paid to US economic data for further guidance. The long - term nature of the competition and game between China and the US is a certainty, but the two sides have a "one - year truce", and concerns about Sino - US trade issues have significantly eased in the short term. The unexpected production cut of an Icelandic smelter highlights the structural problems such as the power bottleneck in the global electrolytic aluminum capacity release. The 45 - million - ton capacity ceiling in China limits the long - term supply elasticity. On the demand side, the loose liquidity environment brought by the Fed's interest - rate cut cycle provides medium - and long - term upward momentum for aluminum prices. - ADC12: The spot price of ADC12 has risen synchronously, with significant cost - side support. The continuous shortage of scrap aluminum supply has pushed up the procurement cost. The supply side is restricted by insufficient raw material circulation and regional policy uncertainty, and some enterprises are operating at a low load. The demand side maintains stable resilience and shows a mild recovery trend. The inventory continues to decline, and the cost rigidity support and the tight supply - demand balance jointly drive the price to strengthen, but high inventory and policy uncertainty still pose constraints. [6] 2. Market Review - In October, the futures prices of alumina and electrolytic aluminum showed a divergent trend. The alumina futures price generally showed a trend of bottom - building in oscillation, falling from a maximum of 2,913 yuan/ton to a minimum of 2,760 yuan/ton. The futures prices of electrolytic aluminum and cast aluminum alloy both increased, with the maximum price of electrolytic aluminum reaching 21,425 yuan/ton and that of cast aluminum alloy reaching 20,920 yuan/ton. [7][8] 3. Macroeconomic Aspects - Sino - US trade: In the short term, concerns about Sino - US trade issues have significantly eased. Although the US announced some trade - restrictive measures in October, through the Sino - US economic and trade consultations in Kuala Lumpur and the meeting between the leaders of the two countries, the two sides reached consensus on many issues, including the cancellation of some tariffs and the suspension of some export control measures for one year. - Industry development: The Fourth Plenary Session of the Central Committee and the "15th Five - Year Plan" proposal have boosted market confidence. The China Non - Ferrous Metals Industry Association called on enterprises to prevent "involution - type" vicious competition and ensure the safety of the industrial chain and supply chain. [12][13][18] 4. Fundamental Aspects - Alumina: The long - term oversupply situation of alumina remains unchanged. In September, China's alumina production was 774,600 tons, a slight month - on - month decrease of 1.7% and a year - on - year increase of 12.7%. The cumulative production from January to September was 6.6836 million tons, a cumulative year - on - year increase of 9.8%. The new capacity is expected to be concentratedly released in the first quarter of 2026. Attention should be paid to the risk of production cuts caused by the heating season, winter stockpiling, and weak spot prices. - Electrolytic aluminum: In September, the weighted average full cost of China's electrolytic aluminum industry was 15,918 yuan/ton, a month - on - month decrease of 193 yuan/ton. The theoretical profit of the industry rose to 4,849 yuan/ton, a month - on - month increase of 301 yuan/ton. The production in September was 381,000 tons, a year - on - year increase of 1.8%. The operating capacity and the proportion of molten aluminum in the industry both increased slightly. As of the end of September, the national electrolytic aluminum production capacity was about 4.584 million tons, and the operating capacity was about 4.406 million tons, both showing a slight increase. Overseas, the sudden production cut of an Icelandic smelter and the possible shutdown of an Australian smelter may cause market concerns about the unstable power supply of overseas aluminum. - Aluminum processing: The operating rates of aluminum processing enterprises are differentiated. The overall operation is stable, with an overall operating rate of 62.4%, a week - on - week decrease of 0.1%. Among them, the operating rate of aluminum profiles is 53.7%, a week - on - week increase of 0.2%; the operating rate of aluminum sheets and strips is 67.0%, a week - on - week decrease of 1.0%; the operating rate of aluminum foils is 71.9%, a week - on - week decrease of 0.4%. - Downstream demand: - Photovoltaic: The new installed capacity of photovoltaic is expected to continue to grow. From January to September 2025, the new installed capacity of photovoltaic was 240.27 GW, a year - on - year increase of 49.35%. In September, the new installed capacity was 9.66 GW, a month - on - month increase of 31.25%. - Real estate: The real estate market is restricted by structural factors, with weak overall investment and purchase demand. From January to September, the construction area, new construction area, and sales area of real estate all decreased year - on - year. - Automobile: The automobile industry continues to maintain high prosperity. In September, the production and sales of automobiles were 3.276 million and 3.226 million respectively, a month - on - month increase of 16.4% and 12.9% respectively, and a year - on - year increase of 17.1% and 14.9% respectively. The production and sales of new energy vehicles also increased significantly. - Home appliances: The home appliance market has entered a seasonal off - season. In September, the production of major home appliances such as air conditioners, refrigerators, washing machines, and color TVs showed different trends. In October, the domestic and export production schedules of household air conditioners decreased year - on - year. - Inventory: Both domestic and foreign exchange inventories are decreasing. The LME aluminum inventory continues to decline, and the SHFE aluminum inventory decreased slightly in the week of October 24. Since mid - October, the social inventory of aluminum ingots has started to decline. As of October 30, the main market electrolytic aluminum inventory in China was 605,000 tons, lower than the same period in 2024. - Recycled aluminum: The production of recycled aluminum remained stable from September to October. As of October 23, the operating rate of the recycled aluminum alloy industry was 58.6%, unchanged week - on - week. The shortage of scrap aluminum resources has led to a slight decline in the operating rate of recycled aluminum alloy last week. In September, the import of unforged aluminum alloy decreased by 13.2% year - on - year. As of October 31, the social inventory and factory inventory of recycled aluminum alloy both decreased week - on - week, indicating a turning point in inventory.
