Group 5: Supply - Side Analysis - Bauxite: Supply disturbances have暂缓, but there is still room for fermentation. High inventory and demand growth, along with decreased shipments from Guinea, are in a game. The price of imported bauxite is expected to be strong and volatile in the short term [24][26]. - Alumina: Supply - side开工 decreased slightly, and inventory continued to increase. The market is in an overall oversupply situation [27][29]. - Electrolytic Aluminum: Supply - side开工 maintained a high level. Due to high profits, electrolytic aluminum enterprises have a strong willingness to start, with an annual 2025开工 rate above 95%. However, the available primary aluminum in the market is limited, and the overall inventory is at a low level [30][34]. Group 6: Demand - Side Analysis - Automobile: In July, automobile production and sales were 2.591 million and 2.593 million respectively, a month - on - month decrease of 7.3% and 10.7%, and a year - on - year increase of 13.3% and 14.7%. From January to July, production and sales were 18.235 million and 18.269 million respectively, a year - on - year increase of 12.7% and 12%. In July, new energy vehicle production and sales were 1.243 million and 1.262 million respectively, a year - on - year increase of 26.3% and 27.4%. From January to July, production and sales were 8.232 million and 8.22 million respectively, a year - on - year increase of 39.2% and 38.5% [41]. - Real Estate: From January to July, the new housing construction area was 352.06 million square meters, a year - on - year decrease of 19.4%. The new residential construction area was 258.81 million square meters, a decrease of 18.3%. The housing completion area was 250.34 million square meters, a year - on - year decrease of 16.5%. The residential completion area was 180.67 million square meters, a decrease of 17.3% [43]. - Power Generation: As of the end of July, the cumulative installed power generation capacity was 3.67 billion kilowatts, a year - on - year increase of 18.2%. The installed wind power capacity was 570 million kilowatts, a year - on - year increase of 22.1%. From January to July, the new installed photovoltaic capacity was 223.25GW, and in July it was 11.64GW, a month - on - month decrease of 18.9% and a year - on - year decrease of 44.7% [45]. Group 7: Strategy Recommendations Alumina and Electrolytic Aluminum - Short - term: Alumina will run weakly and volatilely. For SHFE aluminum, it is advisable to buy on dips, focusing on the fulfillment of the peak - season demand expectation [46][47]. - Medium - to - long - term: Entering the downstream consumption peak season, pay attention to downstream order transactions. If consumption recovers, SHFE aluminum has upward momentum [48]. Polysilicon - Short - term: Frequent news disturbances lead to wide - range price fluctuations. Be vigilant about market sentiment changes, and do not over - position [49][50]. - Medium - to - long - term: The actual downstream demand improvement is limited, and the industry inventory remains high [51].
