Group 1: Report Investment Ratings and Strategies - Glass investment strategy: Weak and oscillating [2] - Soda ash investment strategy: Weak and oscillating [2] - Silicomanganese investment strategy: Oscillating [4] - Ferrosilicon investment strategy: Oscillating [4] Group 2: Core Views - Market sentiment is weak, and steel prices are oscillating downward; glass and soda ash markets are weak and oscillating due to cautious downstream procurement; the dual - silicon market is weak due to unmet peak - season demand [1][3] Group 3: Market Analysis Glass - Yesterday, the glass futures market opened lower and oscillated weakly. Downstream procurement is cautious, mainly for rigid demand. Supply is generally stable, consumption is affected by speculative demand and downstream inventory replenishment, inventory has decreased but overall change is limited, and fundamentals suppress prices. Attention should be paid to macro - policy changes and peak - season demand [1] Soda Ash - Yesterday, the soda ash futures market opened lower and oscillated weakly. Downstream procurement is mainly for rigid - demand replenishment. There are still supply - demand contradictions, and attention should be paid to whether speculative demand weakens. The futures premium suppresses prices, and attention should be paid to new - capacity投产 progress and inventory changes [1] Silicomanganese - Yesterday, the coking coal futures tumbled, and the silicomanganese futures followed suit. The main contract closed at 5,820 yuan/ton, down 46 yuan/ton from the previous day.节前 market transactions were sluggish. This week, production continued to decline, hot - metal production increased slightly, downstream demand remained resilient, and alloy - enterprise inventory increased significantly. In the long run, supply - demand is relatively loose. Considering the futures discount to the spot, prices are expected to oscillate and follow the sector's fluctuations. Attention should be paid to regional policies and cost - support changes [3] Ferrosilicon - Yesterday, the main ferrosilicon futures contract closed at 5,610 yuan/ton, down 70 yuan/ton from the previous day. The market sentiment was average, and the trading atmosphere needed to be strengthened. This week, production and operating rates rebounded slightly, demand increased slightly with hot - metal production, factory inventory decreased month - on - month, and inventory was at a medium level compared to the same period. Currently, there are few supply - demand contradictions, and prices are expected to follow the sector's fluctuations. Attention should be paid to changes in coal and electricity prices at the cost end and regional policies [3] Group 4: Figures - The report includes figures such as Shanghai rebar and hot - rolled coil spot price trends, futures contract closing - price trends, basis trends, cost and profit trends of various products, and spot price trends of raw materials like iron ore, coke, and coking coal [5]

1. Report Industry Investment Rating - The report gives an overall "oscillating" outlook for the black building materials industry, indicating that the prices of sector varieties are expected to remain oscillating in the short - term [5]. 2. Core Viewpoints - Although the pre - holiday restocking logic has ended, the high iron - water production still supports the demand for furnace materials, which in turn supports the steel price at the cost end. As the fourth quarter approaches, the market's expectations for the upcoming important meetings are increasing, so it is expected that the negative feedback in the industrial chain is difficult to form. The prices of sector varieties are expected to remain oscillating before the holiday [1][5]. 3. Summary by Related Catalogs 3.1 Iron Element - **Iron Ore**: The demand for iron ore is at a high level, and the shipments from overseas mines are stable. However, the arrival rhythm is affected by typhoons. Considering the end of pre - holiday restocking demand and the need to further verify the peak - season demand for building materials, the upside space is limited, and the price is expected to oscillate in the short - term [1]. - **Scrap Steel**: The supply and demand of scrap steel both increase, but the steel mills' restocking is nearly over, and the pressure on finished - product prices leads to a contraction in electric - furnace profits. It is expected that the price will oscillate following the finished products in the short - term [1]. 3.2 Carbon Element - **Coke**: Although the steel mills' restocking is over, the rigid demand is strong under the high - iron - water background. The demand for coke is still supported, and the raw - coal price provides strong support. There are still expectations for price increases in the market, and the futures price is expected to oscillate in the short - term [2]. - **Coking Coal**: During the holiday, the coal mine production is expected to decline slightly, and the import of Mongolian coal is suspended, so the overall supply pressure is not large. After the coke price increase is implemented and the profit pressure is relieved, the production can still remain at a high level. The fundamentals of coking coal are strongly supported, and the price is expected to remain oscillating [2]. 3.3 Alloys - **Manganese Silicon**: In the short - term, the high production cost and the peak - season demand expectation support the price of manganese silicon. However, the market's supply - demand expectation is pessimistic, and there is still downward space for the price center after the peak season [2]. - **Silicon Iron**: The short - term peak - season expectation and the firm cost support the price of silicon iron. But the market's supply - demand relationship tends to be loose, and there is still downward pressure on the price after the peak season [2]. 3.4 Glass - The current demand for glass is weak, but there are peak - season and policy expectations. After the middle - stream inventory reduction, there may still be a wave of oscillations. In the long - term, market - oriented capacity reduction is still needed, and if the price returns to fundamental trading, it is expected to oscillate downward [2]. 3.5 Soda Ash - The supply - surplus pattern of soda ash has not changed. It is expected to follow macro - changes and operate with wide - range oscillations. In the long - term, the price center will still decline to promote capacity reduction [2]. 3.6 Specific Product Analysis - **Steel**: The spot market trading of steel is generally weak. The restocking before the holiday is coming to an end, and the speculative intention is weak. The inventory of the five major steel products has started to decline before the holiday, but the inventory level is still higher than the same period last year. The market is still cautious about the peak - season demand and worried about the post - holiday inventory pressure. The short - term futures price is expected to be under pressure, but the downward space is limited due to the upcoming important meetings and cost support [7]. - **Iron Ore**: The shipments from overseas mines have recovered slightly, and the arrival volume at 45 ports has declined slightly. The spot market quotation has fallen, and the port trading has recovered, but the pre - holiday trading is generally weak. The price is expected to oscillate in the short - term [7][8]. - **Scrap Steel**: The supply and demand of scrap steel both increase, but the steel mills' restocking is nearly over, and the electric - furnace profit has shrunk. It is expected to follow the finished products' price in the short - term [9]. - **Coke**: The futures price is running weakly due to the increasing risk - aversion sentiment of funds. The supply is slightly decreasing, and the demand is still supported by high iron - water production. Some steel mills have accepted the price increase, and the futures price is expected to oscillate in the short - term [11]. - **Coking Coal**: The futures price is running weakly due to the increasing risk - aversion sentiment of funds. The supply pressure is not large during the holiday, and the fundamentals are strongly supported. The price is expected to remain oscillating [11][12]. - **Glass**: The demand is weak in reality, but there are peak - season and policy expectations. After the middle - stream inventory reduction, there may be oscillations. In the long - term, it needs market - oriented capacity reduction and is expected to oscillate downward [12]. - **Soda Ash**: The supply - surplus pattern remains unchanged. It is expected to follow macro - changes and oscillate widely. In the long - term, the price center will decline to promote capacity reduction [15]. - **Manganese Silicon**: The downstream restocking demand is nearly over, and the futures price is under pressure. The short - term cost and demand expectations support the price, but there is downward space after the peak season [16][17]. - **Silicon Iron**: The market is pessimistic about the post - holiday demand. The futures price is running weakly. The short - term demand expectation and cost support the price, but there is downward pressure after the peak season [18].

Industry Investment Rating - Not provided in the report 4. Core Viewpoints - Soda ash industry: The short - term contradiction has been alleviated, but the fundamental driving force is still insufficient. The supply is still in surplus, and the oversupply situation has not been effectively improved. The disk price is expected to oscillate weakly, mainly driven by macro - market sentiment [8] - Glass industry: The fundamentals are in a weak balance. The disk price is driven by macro - market sentiment and will gradually return to the fundamental logic, and may oscillate weakly in the short term [10] 5. Summary by Directory 5.1 Soda Ash and Glass Market Review and Operation Suggestions 5.1.1 Soda Ash - **Market Data**: On September 29, the price of the main soda ash futures SA601 contract oscillated downward. The closing price was 1,273 yuan/ton, down 23 yuan/ton, a decline of 1.76%, and the daily position decreased by 51,954 lots [7] - **Fundamentals**: Supply is at a high level, with weekly production rising to 776,900 tons, the highest this year, a 4.19% month - on - month increase. There is no maintenance news, and production is expected to further increase. Demand is good, with total shipments reaching 881,000 tons, a 11.86% month - on - month increase. Downstream, the daily melting volume of float glass is stable at 160,200 tons, and that of photovoltaic glass is 88,700 tons, with a potential production increase in the future. The factory inventory has decreased to 1.6515 million tons [8] 5.1.2 Glass - **Market Data**: The prices of FG601 and FG603 contracts decreased on September 29. FG601 closed at 1,228 yuan/ton, down 29 yuan/ton, a 2.30% decline; FG603 closed at 1,286 yuan/ton, down 28 yuan/ton, a 2.13% decline [7] - **Fundamentals**: The production of float and photovoltaic glass is stable. The market was previously driven by the "anti - involution" sentiment, but without relevant policies, the sentiment cooled down. In mid - September, the "anti - involution" sentiment reignited, and the spot price increased slightly. The Ministry of Industry and Information Technology issued a notice to support the glass price [9][10] 5.2 Data Overview - The report provides multiple data charts, including the price trends of active soda ash and glass contracts, soda ash weekly production, enterprise inventory, central China heavy soda market price, and flat glass production, with data sources from Wind and iFind [14][15][18]

Report Industry Investment Rating No information provided regarding the report industry investment rating. Core Viewpoints of the Report - The overall atmosphere in the commodity market was fair, but prices continued to fluctuate weakly. The Politburo meeting determined the date of the Fourth Plenary Session, and the National Development and Reform Commission is actively promoting a new policy - based financial instrument worth 500 billion yuan, which boosted market sentiment. In the black - series market, trading volume declined slightly near the holiday, and the market remained cautious about holiday - period demand. Although there was a slight rebound in exports this week, the market remained in a weak oscillation. The demand for both hot - rolled coils and rebar was weak, showing prominent characteristics of a non - booming peak season. With the approach of the Fourth Plenary Session, the futures market will maintain a weakly oscillating pattern, and steel prices still face a risk of decline. Attention should be paid to the policy trends of the Fourth Plenary Session [2]. - For iron ore, short - term hot - metal production is expected to remain strong. After the end of steel mills' restocking, demand contradictions will mainly be reflected in the downstream. If the situation of finished products weakens after the holiday, ore prices may adjust downward. It is necessary to focus on downstream demand and inventory conditions after the holiday [5]. - For manganese silicon and ferrosilicon, in the current demand and supply environment, the market may first experience a downward adjustment to release bearish sentiment, and then prices may rise following the expectations of the "Fourth Plenary Session". Manganese silicon may follow the black - series market, and its price may be driven by potential disruptions in the manganese ore market. Ferrosilicon is also likely to follow the black - series market, with relatively low trading value [9][10]. - For industrial silicon, it is expected to oscillate in the short term. After the holiday, attention should be paid to whether there are improvements in the supply - demand structure. If production cuts occur in Southwest China during the dry season and downstream demand remains stable, the high - level inventory may decrease, and the valuation of far - month contracts may increase [14]. - For polysilicon, the current futures price has fallen below the spot price. There has been no progress in capacity integration and downstream price - passing, and the market lacks upward momentum. There is still pressure on the fundamentals, and attention should be paid to the maintenance of leading enterprises [16]. - For glass, the futures market showed wide - range oscillations. Terminal demand remained weak, and downstream purchasing was cautious. Some regions saw inventory reduction, while others faced inventory accumulation. It is advisable to take a slightly bullish view in the short term and focus on subsequent policy trends [19]. - For soda ash, the domestic market remained stable with minor oscillations. Production was generally stable, and demand was tepid. It is expected that the market will continue to oscillate in the short term with limited price fluctuations [21]. Summary by Category Steel (Rebar and Hot - Rolled Coils) Market Information - Rebar: The closing price of the main contract was 3097 yuan/ton, down 17 yuan/ton (- 0.54%) from the previous trading day. The registered warehouse receipts decreased by 2412 tons to 270238 tons, and the main - contract open interest decreased by 49906 lots to 1.926639 million lots. The Tianjin and Shanghai spot prices decreased by 0 and 20 yuan/ton respectively [1]. - Hot - rolled coils: The closing price of the main contract was 3289 yuan/ton, down 24 yuan/ton (- 0.72%) from the previous trading day. The registered warehouse receipts remained unchanged at 28314 tons, and the main - contract open interest decreased by 6738 lots to 1.38447 million lots. The Le Cong and Shanghai spot prices decreased by 30 and 20 yuan/ton respectively [1]. Strategy Viewpoints - Near the holiday, trading volume declined slightly, and the market was cautious about holiday - period demand. Rebar production was basically the same as last week, pre - holiday apparent demand increased, and inventory pressure was marginally relieved. Hot - rolled coil production declined, apparent demand was moderate, and inventory slightly accumulated. Overall, demand for both was weak, and the market was in a weakly oscillating pattern. Steel prices still faced a risk of decline, and attention should be paid to the policy trends of the Fourth Plenary Session [2]. Iron Ore Market Information - The main contract (I2601) closed at 784.00 yuan/ton, down 0.76% (- 6.00 yuan), with an open - interest change of - 34937 lots to 474000 lots. The weighted open interest was 784200 lots. The spot price of PB fines at Qingdao Port was 779 yuan/wet ton, with a basis of 43.93 yuan/ton and a basis ratio of 5.31% [4]. Strategy Viewpoints - Supply: Overseas iron - ore shipments remained stable at a high level. Australian shipments increased slightly, Brazilian shipments decreased slightly, and shipments from non - mainstream countries increased slightly. The near - term arrival volume decreased. - Demand: The average daily hot - metal production was 242.36 tons, up 1.34 tons. Steel mills' profitability declined further. - Inventory: Port inventory increased, and steel mills' imported - ore inventory increased significantly. Before the National Day, steel mills' restocking was almost over. - In the short term, hot - metal production is expected to remain strong. After restocking ends, demand contradictions will mainly be in the downstream. If finished - product conditions weaken after the holiday, ore prices may adjust downward. It is recommended to operate with light positions before the holiday and focus on downstream demand and inventory after the holiday [5]. Manganese Silicon and Ferrosilicon Market Information - Manganese silicon: The main contract (SM601) closed down 0.48% at 5820 yuan/ton. The Tianjin spot price was 5800 yuan/ton, with a basis of 170 yuan/ton. - Ferrosilicon: The main contract (SF511) closed down 0.88% at 5610 yuan/ton. The Tianjin spot price was 5800 yuan/ton, with a basis of 190 yuan/ton [8]. Strategy Viewpoints - The black - series market may first experience a downward adjustment to release bearish sentiment and then rise following the expectations of the "Fourth Plenary Session". Manganese silicon's fundamentals are not ideal, but low manganese - ore port inventory and relatively strong prices may drive its price if the black - series market strengthens. Ferrosilicon is likely to follow the black - series market, with relatively low trading value [9][10]. Industrial Silicon Market Information - The main contract (SI2511) closed at 8610 yuan/ton, down 3.91% (- 350 yuan). The weighted open - interest decreased by 39748 lots to 442464 lots. The spot prices of 553 and 421 in East China remained unchanged, with bases of 690 and 290 yuan/ton respectively [12]. Strategy Viewpoints - Before the holiday, some funds left the market, weakening the futures price. If production cuts occur in Southwest China during the dry season and downstream demand remains stable, the high - level inventory may decrease, and the valuation of far - month contracts may increase. It is expected to oscillate in the short term, and attention should be paid to supply - demand improvements after the holiday [13][14]. Polysilicon Market Information - The main contract (PS2511) closed at 51280 yuan/ton, down 0.36% (- 185 yuan). The weighted open - interest decreased by 10968 lots to 229306 lots. The average spot prices of N - type granular silicon, N - type dense material, and N - type re - feed material remained unchanged, with a basis of 1270 yuan/ton [15]. Strategy Viewpoints - The futures price has fallen below the spot price. There has been no progress in capacity integration and downstream price - passing, lacking upward momentum. There is still pressure on the fundamentals, and attention should be paid to the maintenance of leading enterprises [16].

It is advisable to take a slightly bullish view in the short term and focus on policy trends [19]. - Soda ash: The domestic market remained stable with minor oscillations. Production was generally stable, and demand was tepid. It is expected to continue oscillating in the short term with limited price fluctuations [21].

Industry Investment Rating - The investment rating for the construction materials industry is "Outperform the Market" and is maintained [1] Core Insights - The Ministry of Industry and Information Technology, along with five other departments, has released a "Stabilization Growth Work Plan for the Construction Materials Industry (2025-2026)", which includes five key initiatives aimed at enhancing industry management, promoting technological innovation, expanding effective investment, stimulating consumer demand, and deepening international cooperation [4] - The plan emphasizes strict control over the production capacity of cement and glass, prohibiting new capacity for cement clinker and flat glass, and requiring capacity replacement plans for new and renovated projects [4] - The cement industry is entering its peak season, with demand showing signs of recovery, although growth remains limited. In August 2025, cement production was 148 million tons, a year-on-year decrease of 6.2% [10][5] - The glass industry is experiencing a continuous decline in demand due to real estate impacts, but recent policy catalysts have led to price increases and inventory replenishment in the midstream sector [15][5] Summary by Sections Cement - The cement market is gradually entering the peak season, with overall demand recovering slowly. The construction sector's demand has not fully materialized due to weather disruptions and the pace of demand release [10] - The industry is expected to see a continuous decline in production capacity under the restriction policies, leading to a significant increase in capacity utilization [5] Glass - The glass industry is facing a sustained downward trend in demand due to real estate influences. However, recent policy changes have led to price increases and midstream inventory replenishment [15][5] - The majority of companies in the float glass sector have met environmental requirements, suggesting that the anti-involution policy will not lead to a blanket capacity clearance but will raise environmental standards and costs [5] Fiberglass - The fiberglass sector is experiencing a boom driven by demand from the AI industry, with low dielectric products seeing a significant increase in both volume and price [5] Consumer Building Materials - The profitability of the consumer building materials sector has reached a bottom, with no further downward price pressure. The sector is seeing a strong demand for price increases and profitability improvements, particularly in waterproofing, coatings, and gypsum board [6]
