Group 1: Report Industry Investment Rating - The mid - term outlook for the industry is "Oscillation", indicating that the expected price fluctuations are within plus or minus one standard deviation in the next 2 - 12 weeks [7][97] Group 2: Core Viewpoints of the Report - The short - term impact of military parade production restrictions has ended, and enterprises in the industrial chain are resuming production. Hot metal is expected to return to a high level of 240,000 tons per day, supporting the demand for furnace materials. The performance of peak - season demand and domestic and foreign macro - policies will further intensify the sector's fluctuations [7] - Future market focus will revolve around "downstream inventory replenishment", "peak - season demand", and "overseas interest rate cuts", and attention should be paid to the possibility of the sector rising under the resonance of these three factors [1] Group 3: Summary by Related Catalogs 1. Iron Element - Overseas mine shipments and arrivals at 45 ports increased month - on - month as expected. Due to the military parade production restrictions, hot metal production decreased significantly, but since September 4th, blast furnaces in Tangshan have resumed production intensively. It is expected that the impact on hot metal production reduction will be limited, and it is expected to return to a high level next week. The total iron ore inventory has increased slightly. If downstream inventory replenishment starts before the National Day, the fundamentals are supported, and the future price is expected to oscillate. For scrap steel, the fundamental contradictions are not prominent. The low profit of electric furnaces and tight resources are expected to keep the short - term price oscillating [2] 2. Carbon Element - After the military parade, steel mills will enter the peak - production season, and the short - term price is expected to remain oscillating under demand support. After the military parade, coal mines will gradually resume production but are unlikely to reach the previous high.

In the long - term, there is still significant downward pressure on the price, and attention should be paid to the reduction range of raw material costs. For silicon iron, the current cost still provides some support, but in the long - term, as the market supply - demand relationship becomes looser, the price center will tend to decline, and attention should be paid to the coal market dynamics and the adjustment of electricity costs in the main production areas [2] 4. Glass and Soda Ash - Glass has weak real - world demand, but there are expectations for the peak season and policies. After the mid - stream inventory reduction, there may still be a wave of oscillations. In the long - term, market - oriented capacity reduction is needed, and if the price returns to fundamental trading, it is expected to decline oscillatingly. Soda ash still has an oversupply situation. After the futures price decline, spot trading has increased slightly, and it is expected to run with wide - range oscillations in the future. In the long - term, the price center will decline to promote capacity reduction [3] 5. Individual Product Analysis - **Steel**: The fundamentals are weak, with both supply and demand decreasing and inventory accumulating rapidly. After the military parade, hot metal production may recover, and attention should be paid to the release of short - term inventory replenishment demand during the peak season, which may support the price [8] - **Iron Ore**: Supply and inventory are stable, and there is an expectation of demand recovery. The fundamentals are supported, and the future price is expected to oscillate [9] - **Scrap Steel**: The daily consumption has decreased slightly, and the price is expected to oscillate due to low electric - furnace profits and tight resources [10] - **Coke**: After the military parade, steel mills will enter the peak - production season, and the short - term price is expected to oscillate [11] - **Coking Coal**: After the military parade, coal mines will gradually resume production but are unlikely to reach the previous high. The arrival of the downstream demand peak season still supports the price [12] - **Glass**: Real - world demand is weak, but there are peak - season and policy expectations. After mid - stream inventory reduction, there may be oscillations. In the long - term, market - oriented capacity reduction is needed, and the price is expected to decline oscillatingly [12] - **Soda Ash**: The oversupply situation remains unchanged. After the futures price decline, spot trading has increased slightly, and it is expected to run with wide - range oscillations. In the long - term, the price center will decline to promote capacity reduction [15] - **Manganese Silicon**: The cost support is weak, and there is significant downward pressure on the price in the long - term. Attention should be paid to the reduction range of raw material costs [16] - **Silicon Iron**: The current cost provides some support, but in the long - term, the price center will tend to decline. Attention should be paid to the coal market dynamics and the adjustment of electricity costs in the main production areas [17]

1. Report Industry Investment Ratings - Glass: Oscillating weakly [2] - Soda Ash: Oscillating weakly [2] - Ferrosilicon Manganese: Oscillating [4] - Ferrosilicon: Oscillating [4] 2. Core Views of the Report - Glass demand remains weak with high inventory and insufficient production cuts, leading to a weak price trend; soda ash supply is high and demand may weaken further with new capacity coming online, so the price is under pressure [1] - The supply - demand surplus in the ferrosilicon manganese and ferrosilicon industries is obvious, and losses are needed to suppress production release, with prices expected to follow the sector's fluctuations [3] 3. Summary by Directory Glass and Soda Ash - **Market Analysis**: Glass futures oscillated, and downstream procurement was cautious; soda ash futures had a narrow - range oscillation, and downstream demand was mainly for replenishing inventory [1] - **Supply - Demand and Logic**: Glass demand is weak, high inventory pressure persists, and production cuts are insufficient; soda ash supply is high, and demand may weaken further as new capacity is put into operation [1] - **Strategy**: Glass and soda ash are both expected to oscillate weakly [2] Ferrosilicon Manganese and Ferrosilicon - **Market Analysis**: Ferrosilicon manganese futures fell 0.21% to 5732 yuan/ton, and the spot price was 5650 - 5730 yuan/ton; ferrosilicon futures fell 0.14% to 5520 yuan/ton, and the spot price was slightly reduced [3] - **Supply - Demand and Logic**: Both ferrosilicon manganese and ferrosilicon have increased production and sales and reduced inventories, but the supply - demand surplus is still obvious, and losses are needed to suppress production release [3] - **Strategy**: Both ferrosilicon manganese and ferrosilicon are expected to oscillate [4]

Report Industry Investment Rating - The mid - term outlook for the entire black building materials sector is "oscillating" [5]. - For individual varieties, the mid - term outlooks for steel, iron ore, scrap steel, coke, coking coal, glass, soda ash, manganese silicon, and ferrosilicon are all "oscillating" [7][8][9][11][12][13][15][16][17]. Core Viewpoints of the Report - The impact of the military parade on the sector is gradually diminishing. As coal - coking and steel enterprises resume production, the demand for furnace materials is increasing, especially for iron ore. However, the overall upward movement of the sector's prices depends on the start of the replenishment logic under continuous demand improvement. The increasing expectation of a US interest rate cut may further boost the sector sentimentally [1]. - Overall, the terminal demand during the peak season needs to improve for the sector to rise again. Attention should also be paid to the boosting effect of strengthened policy expectations [5]. Summary by Related Catalogs 1. Overall Situation of the Black Building Materials Sector - The intraday futures prices of the sector rose and then fell, and the night - session continued the oscillating and pressured trend, mainly due to the impact of the military parade on the supply - demand side of the industrial chain. After the parade, some enterprises resumed production, increasing the demand for furnace materials, especially for iron ore. The overall upward movement of the sector's prices requires the start of the replenishment logic under continuous demand improvement. The increasing expectation of a US interest rate cut may further boost the sector [1]. 2. Analysis of Different Elements and Products Iron Element - Overseas mine shipments and arrivals at 45 ports increased month - on - month, in line with expectations. The small - sample hot metal production decreased slightly, and steel enterprises are expected to resume production. This week, iron ore ports reduced inventory, the number of ships at berth increased, factory inventories decreased, and the total inventory decreased slightly. The fundamentals support the price, and it is expected to oscillate in the future. The fundamentals of scrap steel have no prominent contradictions. The low profit of electric furnaces due to pressured finished - product prices and the tight supply lead to an expected short - term price oscillation [2]. Carbon Element - After the military parade, steel mills will enter the peak production season, and the demand will support the short - term price to remain oscillating. After the parade, coal mines will gradually resume production but are unlikely to reach the previous high. The upcoming peak demand season for downstream products still supports the coking coal price [2]. Alloys - Manganese ore and coke prices are weak, and the cost support for manganese silicon is insufficient. The market supply - demand expectation is pessimistic, and there is still significant downward pressure on the price in the medium - to - long - term. Attention should be paid to the reduction range of raw material costs. The current cost of ferrosilicon has some support, but the supply - demand relationship will become looser in the future, and the price center will tend to decline in the medium - to - long - term. Attention should be paid to the dynamics of the coal market and the adjustment of electricity costs in the main production areas [2]. Glass - The current demand for glass is weak, but there are expectations for the peak season and policies. After the mid - stream reduces inventory, there may be another round of oscillations. In the long - term, market - oriented capacity reduction is needed, and if the price returns to fundamental trading, it is expected to decline while oscillating [2][12]. Soda Ash - The supply surplus pattern of soda ash remains unchanged. After the futures price declines, spot - futures trading volume increases slightly. It is expected to oscillate widely in the future. In the long - term, the price center will decline to promote capacity reduction [2][15]. 3. Analysis of Individual Varieties Steel - The spot market trading volume of steel is generally weak. Affected by the military parade, steel production and demand both decreased, and inventory continued to accumulate. The market is cautious about the peak - season demand. After the parade, the hot metal production may return to a high level, and attention should be paid to the replenishment demand during the peak season, which may support the futures price [7]. Iron Ore - The overseas mine shipments and arrivals at 45 ports increased month - on - month, in line with expectations. The small - sample hot metal production decreased slightly, and steel enterprises are expected to resume production. The port inventory decreased, the number of ships at berth increased, factory inventories decreased, and the total inventory decreased slightly. The fundamentals support the price, and it is expected to oscillate in the future [7]. Scrap Steel - The supply of scrap steel decreased this week. Due to the pressured finished - product prices, the electric - furnace profit is low, and the daily consumption of scrap steel in both electric furnaces and blast furnaces decreased. The factory inventory decreased slightly, and the inventory - available days are at a low level. The fundamentals have no prominent contradictions, and the price is expected to oscillate in the short - term [9]. Coke - The expectation of the eighth round of price increases has basically failed, and the market sentiment is bearish. After the parade, steel mills will enter the peak production season, and the demand will support the short - term price to remain oscillating [9][11]. Coking Coal - After the military parade, coal mines will gradually resume production but are unlikely to reach the previous high. The upcoming peak demand season for downstream products still supports the coking coal price. Attention should be paid to regulatory policies, coal mine resumption, and Mongolian coal imports [11][12]. Glass - The demand for glass is weak, but there are expectations for the peak season and policies. After the mid - stream reduces inventory, there may be another round of oscillations. In the long - term, market - oriented capacity reduction is needed, and if the price returns to fundamental trading, it is expected to decline while oscillating [12]. Soda Ash - The supply surplus pattern of soda ash remains unchanged. After the futures price declines, spot - futures trading volume increases slightly. It is expected to oscillate widely in the future. In the long - term, the price center will decline to promote capacity reduction [13][15]. Manganese Silicon - The prices of manganese ore and coke are weak, and the cost support for manganese silicon is insufficient. The market supply - demand expectation is pessimistic, and there is still significant downward pressure on the price in the medium - to - long - term. Attention should be paid to the reduction range of raw material costs [16]. Ferrosilicon - The current cost of ferrosilicon has some support, but the supply - demand relationship will become looser in the future, and the price center will tend to decline in the medium - to - long - term. Attention should be paid to the dynamics of the coal market and the adjustment of electricity costs in the main production areas [17].

1. Report Industry Investment Rating No relevant information provided. 2. Core View of the Report - The overall atmosphere in the commodity market is weak, with the prices of finished steel products showing a weak and volatile trend. The demand for finished products is clearly weak, the profits of steel mills are gradually shrinking, and the weak characteristics of the futures market are becoming more prominent. If the demand cannot be effectively improved in the future, the prices may continue to decline. The raw material end is more resilient than the finished products, and attention should be paid to the potential impact of safety inspections and environmental protection restrictions. It is recommended to continuously track the progress of terminal demand recovery and the support of the cost end for the prices of finished products [3]. - The price of iron ore is expected to be weak and volatile in the short term. The recent increase in overseas mine shipments may bring pressure, and the strong raw material prices continue to affect the profits of steel mills. The fundamentals of finished products are relatively weak, and the futures market shows that raw materials are stronger than finished products. The impact of production restrictions on iron water production in Tangshan steel mills needs to be observed [6]. - The prices of ferrosilicon and manganese silicon continue to be weak. The over - supply pattern of manganese silicon remains unchanged, and its price is expected to remain weak until mid - October. There is no obvious contradiction in the supply - demand fundamentals of ferrosilicon, and attention should be paid to changes in downstream terminal demand and relevant policies. Hedging funds are advised to seize hedging opportunities [9][11]. - The price of industrial silicon is expected to be weak and volatile in the short term, with the supply pressure from resuming production greater than the demand support. The price of polysilicon continues to be in a pattern of "weak reality, strong expectation", with high volatility and possible upward exploration if favorable news is released [14][15]. - The price of glass is expected to be weakly volatile in the short term, and its long - term trend depends on policy support and demand improvement. The price of soda ash is expected to be volatile in the short term, and its price center may gradually rise in the long term, but the upward space is limited due to the contradiction between supply and demand [17][18]. 3.
