Report Investment Rating No information provided on the industry investment rating. Core Viewpoints - The fundamentals of soda ash show strong supply and weak demand. In the short term, it is expected to mainly fluctuate weakly [2]. - The main logic is that the supply of soda ash is at a high level, the terminal demand is declining, the inventory is at a high level in the same period, and the mismatch between supply and demand in the industry has not been effectively improved [5]. Summary by Directory 1. Soda Ash Futures Market - The closing price of the main contract decreased from 1311 yuan/ton to 1296 yuan/ton, a decline of 1.14%. The low - end price of heavy soda ash in Shahe remained unchanged at 1205 yuan/ton. The main basis increased from - 106 yuan/ton to - 91 yuan/ton, a change of - 14.15% [6]. 2. Soda Ash Spot Market - The low - end price of heavy soda ash in Hebei Shahe is 1205 yuan/ton, unchanged from the previous day [12]. - The profit of heavy soda ash in North China's ammonia - soda process is - 48.10 yuan/ton, and that in East China's co - production process is - 58 yuan/ton. The production profit of soda ash has rebounded from a historical low [15]. - The weekly industry operating rate of soda ash is 82.47%, showing a seasonal decline. The weekly output is 71.91 tons, including 38.32 tons of heavy soda ash, at a historical high [18][20]. - From 2023 to 2025, there have been significant expansions in soda ash production capacity, with planned new capacities of 640, 180, and 750 tons respectively. The actual new capacity in 2025 is 100 tons [22]. 3. Fundamental Analysis - Demand - The weekly sales - to - production ratio of soda ash is 97.80% [25]. - The daily melting volume of national float glass is 15.96 tons, and the operating rate is 75.49% and stable [28]. - The price of photovoltaic glass continues to fall. Under the influence of the "anti - involution" policy, the industry has cut production, and the daily melting volume in production continues to decline significantly [34]. 4. Fundamental Analysis - Inventory - The national soda ash inventory in factories is 186.75 tons, a decrease of 2.27% from the previous week, and the inventory is running above the five - year average [37]. 5. Fundamental Analysis - Supply - Demand Balance Sheet - The supply - demand balance sheet from 2017 to 2024E shows the changes in effective capacity, production, operating rate, import, export, net import, apparent supply, total demand, supply - demand difference, capacity growth rate, production growth rate, apparent supply growth rate, and total demand growth rate of soda ash [38]. 6. Influencing Factors - **Positive factors**: The peak summer maintenance period is approaching, and production will decline [3]. - **Negative factors**: Since 2023, the production capacity of soda ash has expanded significantly, and there are still large production plans this year. The production is at a historical high. The downstream photovoltaic glass of heavy soda ash has cut production, reducing the demand for soda ash. The positive sentiment of the "anti - involution" policy has faded [5].

1. Report Industry Investment Ratings - No specific industry investment ratings are provided in the report. 2. Core Views - The Jackson Hole Global Central Bank Annual Meeting saw the Fed Chair's dovish stance, increasing the certainty of a September rate cut, but short - term leveraged funds flowing in too quickly pose risks to the stock index, which may face a slight shock adjustment [3]. - The bond market lacks its own drivers, and its sentiment is significantly suppressed by the equity market. It is in a range - bound state, and the short - term 10 - year Treasury active bond yield around 1.8% may be a resistance level for the upward movement of interest rates [3]. - The dovish attitude of Fed officials continues to suppress the US dollar, and precious metals are strengthening and approaching the upper limit of the fluctuation range [3]. - The EC main contract of the container shipping index (European line) shows a weak trend [3]. - Steel prices are in a weak decline, and iron ore follows steel prices, with a trading range of 770 - 820 [3]. - Copper prices have weak short - term drivers and are in a narrow - range shock [3]. - The supply and demand pressure of PX is not large, but the short - term driver is limited; PTA is under short - term pressure in a weak market atmosphere, but the supply - demand expectation is tight [3]. - The inventory of bottle chips has decreased, and it follows the raw materials, with limited short - term processing fee upward space [3]. - The overseas supply outlook for sugar is relatively loose, and the short - selling position should be held [3]. - The issuance of sliding - scale tax quotas for cotton is lower than expected, and the 01 contract is short - term strong [3]. 3. Summary by Related Catalogs Stock Index - The current basis rates of the main contracts of IF, IH, IC, and IM are 0.05%, 0.06%, - 0.36%, and - 0.67% respectively. The technology main line strongly pulled up, and the stock index reversed intraday. It is recommended to wait until after the earnings report disclosure in September to decide the next - round direction [3]. Treasury Bonds - The stock market is strong, and the bond market sentiment is weak again, in a range - bound state. The short - term 10 - year Treasury active bond yield around 1.8% may be a resistance level for the upward movement of interest rates, corresponding to support for the T2512 contract around 107.4 - 107.6. The short - term bond futures can be temporarily on the sidelines [3]. Precious Metals - Gold is in a shock - strengthening trend. Hold the bull spread strategy of buying gold option AIU2512C776 and selling AU2512C792; hold the long position of silver [3]. Container Shipping Index (European Line) - The EC main contract shows a weak trend. Short the 12 - contract on rallies [3]. Steel and Black Metals - Steel prices are in a weak decline, and it is recommended to wait and see. Iron ore follows steel prices, with a range of 770 - 820, and a strategy of long iron ore and short coking coal can be adopted.

1. Report Industry Investment Rating - The report provides a mid - term outlook for various black building materials, mostly rated as "oscillating". The specific ratings for each variety are as follows: - Steel: Oscillating [8] - Iron ore: Oscillating [9] - Scrap steel: Oscillating [10] - Coke: Oscillating [11] - Coking coal: Oscillating [12] - Glass: Oscillating [14] - Soda ash: Oscillating [18] - Manganese silicon: Oscillating [19] - Ferrosilicon: Oscillating [20] 2. Core Viewpoints of the Report - The policy's mention of stabilizing the growth of the steel industry had a limited positive impact, and the futures market showed a muted reaction. The overall black building materials market is expected to oscillate, with potential for a slight rebound if there are positive drivers. Attention should be paid to the demand performance in the coming weeks and the recovery of furnace material supply [1][2]. - The black building materials market's cost has some support, but the expected weak demand during the peak season restricts the upside potential. The market will continue to be affected by factors such as the implementation of policies and the performance of terminal demand [6]. 3. Summary by Variety 3.1 Steel - Core logic: The steel industry's growth - stabilizing plan has led to a slight increase in the futures price. Steel spot trading is average, with more low - price transactions. This week, some steel mills resumed production and increased output, resulting in an increase in rebar production and stable hot - rolled coil production. During the transition between the off - season and peak season, rebar's apparent demand has improved month - on - month but is still lower year - on - year, and inventory continues to accumulate. The demand for hot - rolled coils remains resilient, and inventory also accumulates under high production. The apparent demand for medium - thick plates and cold - rolled products has weakened, and inventory has increased. The supply and demand of the five major steel products have both increased, and inventory has continued to accumulate [8]. - Outlook: During the off - season to peak - season transition, steel inventory continues to accumulate, and the market is cautious about the peak - season demand. Supply and demand will be affected around the military parade, and the impact of blast furnace production restrictions may be reflected in next week's data. After the parade, pig iron production may remain at a high level, and the cost side still has some support. It is expected that the futures price will oscillate widely in the short term. Focus on steel mill production restrictions and terminal demand [8]. 3.2 Iron Ore - Core logic: Port trading volume decreased slightly. The spot market prices increased, and port trading volume decreased. Overseas mine shipments decreased month - on - month, and the arrival volume at 45 ports slightly declined, approaching last year's level. Total supply is relatively stable. Pig iron production decreased slightly, and there is an expectation of a decline in pig iron production as some steel mills in Hebei enter maintenance at the end of the month, but the impact is limited. After the parade, iron ore demand may return to a high level. This week, port inventory decreased, berthing increased, and factory inventory decreased, resulting in a slight decline in total inventory [3][8]. - Outlook: With high iron ore demand, stable supply and inventory, and limited negative fundamental drivers, the price is expected to oscillate in the future [9]. 3.3 Scrap Steel - Core logic: The arrival volume of scrap steel decreased month - on - month this week. Due to the pressure on finished products, the profit of electric arc furnaces is low, and the daily consumption of scrap steel in electric arc furnaces and blast furnaces has decreased. Factory inventory has slightly decreased, and the available inventory days are at a low level [10]. - Outlook: The fundamental contradictions of scrap steel are not prominent. Although the profit of electric arc furnaces is low due to the pressure on finished product prices, resources are still tight. It is expected that the price will oscillate in the short term [10]. 3.4 Coke - Core logic: In the futures market, the implementation of the steel growth - stabilizing plan and the ongoing negotiation of the eighth round of price increases have led to an oscillating market. In the spot market, the price in Rizhao Port decreased. As the military parade approaches, the production of some coking enterprises is restricted, while others maintain normal production. Downstream steel mills have good profits and high production willingness, but due to the military parade, the production of some steel mills in North China will be restricted, and transportation is tightened, resulting in low inventory in local steel mills and common rush - order situations. Some coking enterprises have started to accumulate inventory, but overall, the upstream coking enterprise inventory is still at a low level [11]. - Outlook: As the military parade approaches, the production restrictions on coke are stronger than those on steel mills. In the short term, the coke market will remain tight. Although it is difficult for the eighth round of price increases to be implemented, the futures price will still be supported before the parade [11]. 3.5 Coking Coal - Core logic: In the futures market, due to the tightening of coal mine safety supervision before the military parade and the implementation of the steel growth - stabilizing plan, the market oscillates. In the spot market, the price of some coking coal decreased. On the supply side, the production of some coal mines is restricted due to accidents and other factors, and safety inspections are increasing. Some coal mines have voluntarily reduced production, resulting in a tightening of coal mine production before the parade. On the import side, the average daily customs clearance at the Ganqimaodu Port remains high, and the impact of the military parade is currently limited. On the demand side, the eighth round of coke price increases has started, with regional differences. Coking production in some areas is restricted, and the short - term rigid demand for coking coal has slightly decreased. Downstream enterprises are mainly purchasing on - demand, and spot trading is weak and stable. Some coal mines have started to accumulate inventory, but overall, the previous inventory reduction to a low level and a large number of pre - sold orders mean that there is no obvious inventory pressure for now [3][12]. - Outlook: Before the military parade, the coking coal market shows a pattern of weak supply and demand. Short - term fundamental contradictions are not prominent. Although it is difficult for the eighth round of coke price increases to be implemented, the futures price will still be supported before the parade [12]. 3.6 Glass - Core logic: The spot price is stable. The demand in the off - season has decreased, but the deep - processing orders have increased month - on - month, and the inventory days of raw glass have increased significantly to a high level this year. Downstream has limited ability to replenish inventory. As the traditional peak season approaches, some upstream manufacturers are promoting sales by raising prices, and downstream purchasing has stabilized overall. On the supply side, a new production line has been ignited recently, and there are still production lines to be ignited in Shahe. The daily melting volume is expected to increase steadily. As the delivery approaches, the spot price has decreased, and the delivery logic is becoming more dominant. The fundamentals are still weak, and the reverse - spread logic is still stable. It is expected that the futures and spot prices will oscillate widely in the short term [14]. - Outlook: The actual demand is weak, but the policy expectation is strong, and the raw material price is strong. After the delivery contradiction trading, the far - month contract still has a premium. In the long term, capacity reduction through marketization is still needed, and if the price returns to fundamental trading, it is expected to oscillate downward [16][17]. 3.7 Soda Ash - Core logic: The price of heavy soda ash delivered to Shahe decreased. The sentiment in the domestic commodity market is weakening, and as the delivery approaches, the fundamental logic returns, with a neutral macro - environment. On the supply side, the production capacity has not been cleared, and long - term pressure remains. In the short term, the production in Alxa is affected, but it is expected that both production capacity and output will increase in the future. On the demand side, heavy soda ash is expected to maintain rigid - demand purchasing. There are still some production lines that have not produced glass, and the daily melting volume of float glass is expected to be stable, while the daily melting volume of photovoltaic glass has bottomed out and rebounded. The demand for heavy soda ash is expected to increase steadily. The downstream purchasing of light soda ash has remained flat, but the overall downstream inventory - replenishment sentiment is weak, and there is resistance to high prices. As the shipping problem is resolved, the inventory in the middle reaches has accumulated, and the downstream willingness to receive goods is weak. The futures price may return to fundamental trading [18]. - Outlook: The oversupply situation has not changed. After the futures price decline, spot trading has increased slightly. It is expected that the price will oscillate widely in the future. In the long term, the price center will continue to decline to promote capacity reduction [18]. 3.8 Manganese Silicon - Core logic: The futures price of manganese silicon first declined weakly and then oscillated upward. In the spot market, a new round of steel procurement has started, and the market is waiting and watching. The spot price adjustment is small. The October manganese ore price quote is flat month - on - month. Recently, port trading has been sluggish, but miners are reluctant to reduce prices, and port ore prices have not fluctuated much. On the demand side, steel mills' profits are good, and finished product production is still at a high level. As the military parade approaches, steel production will decline slightly, but in September, as the peak season begins and after the parade, finished product production is expected to increase. On the supply side, manganese silicon production has reached a high level this year, and market supply pressure is gradually accumulating [19]. - Outlook: The current market inventory pressure is temporarily controllable. Due to cost support, the short - term decline in manganese silicon prices is limited. However, as the market supply - demand relationship becomes looser, there is still downward pressure on prices in the long term. Pay attention to the reduction in raw material costs [19]. 3.9 Ferrosilicon - Core logic: The futures price of ferrosilicon continued to decline. In the spot market, trading was weak, but manufacturers were reluctant to sell at low prices, and the spot price adjustment was small. On the supply side, manufacturers' resumption of production has accelerated recently, and ferrosilicon production has gradually reached a high level. On the demand side, steel production has remained stable at a high level, and the steel - making demand for ferrosilicon still has some resilience. As the military parade approaches, steel production will decline, but in the peak season, finished product production will gradually increase. In the metal magnesium market, supply pressure has increased, while demand is still weak, and the magnesium ingot price is under pressure [20]. - Outlook: The current market inventory pressure is not large. Due to cost support, the short - term downward adjustment space for ferrosilicon prices is limited. However, the future market supply - demand outlook is pessimistic, and in the long term, the price center will tend to decline. Pay attention to the dynamics of the coal market and the adjustment of electricity costs in major production areas [20].

Group 1: Report Industry Investment Ratings - No industry investment ratings are provided in the reports. Group 2: Core Views Rubber Industry - New rubber listing is slow, overseas ship arrivals are few, inventory may continue to decline, fundamentals remain strong, and there is still upward potential. The 01 contract range is expected to be between 15,000 - 16,500. Pay attention to the raw material supply during the peak production period in the main producing areas. If the raw material supply is smooth, consider short - selling at high prices [1]. Industrial Silicon Industry - The cost of industrial silicon is rising, and there are news of capacity clearance. In August, supply and demand both increased, maintaining a tight balance. In the long - term, if some capacity is cleared, supply pressure will decrease. It is recommended to buy on dips, but be aware of the pressure from inventory and warehouse receipts [2]. Polysilicon Industry - In August, polysilicon supply and demand both increased, but the supply growth rate was higher, still facing inventory accumulation pressure. Future warehouse receipts are expected to increase. The price will mainly fluctuate at a high level, with the lower limit of the price range rising to 47,000 yuan/ton and the upper limit between 58,000 - 60,000 yuan/ton. It is recommended to buy on dips, and consider short - selling by buying put options at high prices when volatility is low [4]. Log Industry - The current main contract is the 2511 contract, and the market value fluctuates around the delivery cost and receiving value. The fundamentals are expected to improve marginally. The demand remains firm, and the inventory continues to decline. It is recommended to consider buying the 2601 contract on dips [5]. Glass and Soda Ash Industry - **Soda Ash**: The market is in a weak and volatile state. There is no growth expectation for demand, and the inventory may be further pressured. It is recommended to hold short positions [6]. - **Glass**: The market is also in a weak and volatile state. The market has a negative feedback loop, with the near - term 09 contract facing weak reality and the far - term 01 contract facing weak expectations. High - level short positions can be closed for profit and wait for new driving factors [6].

Report Industry Investment Ratings No specific industry investment ratings are provided in the report. Core Viewpoints of the Report The report analyzes the market conditions of various asset classes including macro - finance, stocks, precious metals, black metals, non - ferrous metals, energy chemicals, and agricultural products. It points out that short - term macro upward drivers are marginally strengthening, with focus on domestic incremental stimulus policies, loose expectations, Sino - US trade negotiation progress, and implementation of domestic incremental policies. Different asset classes are expected to have different short - term trends, mainly presenting震荡 (oscillation) or震荡偏强 (oscillation with a slightly upward trend) patterns [2][3]. Summaries by Relevant Catalogs Macro Finance - Overseas: The second - quarter GDP had a year - on - year growth rate of 3.3%, higher than the expected 3.1%. After the New York Fed President Williams hinted at a possible rate cut, market expectations for a Fed rate cut next month increased, the US dollar index was weak, and global risk appetite increased. - Domestic: China's economic data in July slowed down and was below expectations. The Ministry of Commerce will introduce policies to expand service consumption in September. With the extension of the Sino - US tariff truce for 90 days and increased US easing expectations, short - term external risks decreased, and domestic risk appetite increased. - Asset Performance: Stocks are expected to be short - term oscillatory and slightly stronger, with short - term cautious long positions; treasury bonds are expected to be high - level oscillatory in the short term, with cautious observation; commodities: black metals, non - ferrous metals, and energy chemicals are short - term oscillatory, with cautious observation; precious metals are high - level and slightly stronger oscillatory in the short term, with cautious long positions [2]. Stocks - The domestic stock market fell significantly due to the drag of sectors such as clothing and home textiles, biomedicine, and liquor. - The short - term macro upward driver is marginally strengthening, with focus on Sino - US trade negotiation progress and implementation of domestic incremental policies. Short - term cautious observation is recommended [3]. Precious Metals - Gold and silver prices rose on Thursday. The Fed's independence concerns and the weakening US dollar supported the upward movement of precious metals. - The number of initial jobless claims in the US decreased, and the second - quarter GDP was stronger than expected. The market is focused on the PCE data to be released on Friday. Gold has strong short - term support, but be wary of the Fed's changing attitude [3][4]. Black Metals Steel - Steel futures and spot prices rebounded slightly on Thursday, and trading volume increased slightly. The expectation of steel production cuts in the next two years has increased. - The fundamentals remain weak, with an increase in the inventory of five major steel products and a decline in the apparent consumption of some products. Supply is mixed, with an increase in rebar production and a slight decrease in hot - rolled coil production. There is a possibility of further production restrictions in the north in early September, and the steel market may continue to rebound [5]. Iron Ore - Iron ore futures and spot prices rebounded significantly on Thursday. Steel mills' profits are high, but due to production restrictions in the north in the next week, steel mills' procurement is cautious. - Global iron ore shipments and arrivals decreased this week. Port inventories decreased slightly on Monday. Iron ore prices are expected to be range - bound in the short term [5]. Silicon Manganese/Silicon Iron - Silicon iron prices were flat, and silicon manganese prices rebounded slightly on Thursday. The demand for ferroalloys is okay as the production of five major steel products continues to increase. - The production of silicon manganese in Inner Mongolia is stable, with some minor production fluctuations. There are new production capacity plans in the future, and the daily output may be affected by 500 - 800 tons. The prices of ferroalloys are expected to be range - bound in the short term [6][7]. Soda Ash - The soda ash main contract oscillated on Thursday. Supply increased due to the return of previous maintenance, and there is supply pressure with new capacity coming online. - Demand remained stable week - on - week, but overall demand support is weak. Profits decreased week - on - week. Soda ash is expected to be range - bound in the short term [7]. Glass - The glass main contract oscillated on Thursday. Supply remained stable, and demand is difficult to improve significantly. - Profits decreased as glass prices fell. With the support of real - estate news, glass is expected to be range - bound in the short term [7]. Non - Ferrous Metals and New Energy Copper - Due to concerns about US tariffs and the expected tightening of the Japanese central bank's monetary policy, and the weakening of domestic demand, the strong copper price is difficult to sustain [9]. Aluminum - Aluminum prices fell slightly on Thursday, and inventories continued to increase. The medium - term upward space for aluminum prices is limited, and it is expected to be oscillatory in the short term [9]. Aluminum Alloy - The supply of scrap aluminum is tight, the cost of recycled aluminum plants is rising, and demand is weak. The price is expected to be oscillatory and slightly stronger in the short term, but the upward space is limited [9]. Tin - The supply - side开工率 (operating rate) increased, and the mine supply is expected to be loose. The demand side is weak, but the price decline has stimulated downstream replenishment. Tin prices are expected to be oscillatory in the short term, with support from smelter maintenance and peak - season expectations, but restricted by high tariffs,复产 expectations (restoration of production expectations), and weak demand [10]. Lithium Carbonate - The lithium carbonate main contract fell on Thursday. After the previous sentiment subsided, it is expected to be widely oscillatory, with short - term short positions and long - term long positions [11]. Industrial Silicon - The industrial silicon main contract fell on Thursday. With the oscillation of black metals and polysilicon, industrial silicon is expected to be weakly oscillatory [11]. Polysilicon - The polysilicon main contract fell on Thursday. The production in August is approaching 130,000 tons, and the number of warehouse receipts is increasing. It is facing a game between strong expectations and weak reality. It is recommended to short on rebounds [12]. Energy and Chemicals Crude Oil - The possibility of more Russian oil supply entering the market in the short term has decreased, and oil prices rose slightly on Thursday. However, the market has limited risk premium digestion, and short - term oil prices are expected to be weakly oscillatory [14]. Asphalt - Due to limited oil price changes, the asphalt main price remained almost unchanged. The spot market has slightly improved, but inventory removal is limited. Asphalt is expected to be weakly oscillatory in the short term [14]. PX - After the price increase due to Zhejiang Petrochemical's maintenance, PX supply is tight, and it is expected to be oscillatory in the short term, waiting for changes in PTA devices [14].

It is expected to be oscillatory in the short term, with attention to the downstream recovery space [15]. Ethylene Glycol - Ethylene glycol prices continued to decline, and port inventories decreased slightly. It is expected to be narrowly oscillatory in the short term, with support from downstream start - up recovery, but supply pressure is still large [16]. Short - Fiber - Short - fiber prices fell slightly due to sector resonance. Terminal orders have increased seasonally, and it is recommended to short on highs in the medium term [16]. Methanol - The restart of inland devices and concentrated arrivals have pressured prices, but there is some support from the reflux window and the planned restart of MTO devices. Methanol is expected to be oscillatory [16]. PP - The supply - side pressure is increasing, and demand is showing signs of recovery. The 09 contract is expected to be weakly oscillatory, and attention should be paid to the peak - season inventory situation of the 01 contract [16]. LLDPE - The supply - side pressure remains, and demand is showing a turning point. The 09 contract is expected to be weakly oscillatory, and attention should be paid to demand and inventory situation of the 01 contract [17]. Agricultural Products US Soybeans - The CBOT soybean price was supported by the continuous improvement of US new - season soybean exports. The export sales of the current market year decreased, while the next - year exports increased significantly. Pakistan is expected to sign a purchase agreement [19]. Soybean Meal and Rapeseed Meal - The pressure of continuous inventory accumulation of domestic oil mills' soybeans and soybean meal has eased, but the near - month/spot risk has not subsided. Rapeseed meal has an upward fluctuation basis due to low inventory and few long - term purchases [19]. Oils - Rapeseed oil port inventories are decreasing, and the supply of soybean oil is expected to strengthen. Palm oil is in the production - increasing cycle, and the market is expected to be oscillatory [20]. Corn - The national corn price is running weakly, but the futures price has entered a relatively low - valuation range, and the possibility of breaking through last year's range is small [20]. Hogs - Group farms continued to reduce weight in August, and the pig price did not rebound as expected at the end of August. The theoretical slaughter volume will increase in September, but there is no need to be overly pessimistic. Some local areas have started purchasing and storage [20][21].

1. Report Industry Investment Ratings - There is no information about industry investment ratings in the provided reports. 2. Core Views Natural Rubber - Affected by the dovish stance of the Federal Reserve, market sentiment is positive, driving up rubber prices. However, the trading atmosphere in the spot market has cooled, and tire factories are cautious about purchasing high - priced raw materials, limiting the upside of rubber prices. It is expected that rubber prices will mainly fluctuate within a range, with the 01 contract's range referring to 15,000 - 16,500. Follow the raw material supply situation during the peak production season in the main producing areas, and consider short - selling at high levels if the raw material supply is smooth [1]. Polysilicon - In August, the supply and demand of polysilicon both increased, but the supply growth rate was larger, still facing inventory accumulation pressure. The price will mainly fluctuate at a high level, with the lower limit of the price fluctuation range rising to 47,000 yuan/ton and the upper limit likely to be between 58,000 - 60,000 yuan/ton. It is recommended to try long positions on dips. When the price is high, consider buying put options to short when the volatility is low [3]. Industrial Silicon - From the cost side, raw material prices are rising, and the electricity price in the southwest region will gradually increase during the dry season, raising the cost center of industrial silicon. Although the current output of industrial silicon has increased month - on - month, there are also news of capacity clearance, and small furnaces may be shut down. In August, supply and demand both increased, maintaining a tight balance. If some capacity is cleared in the long - term, the supply pressure will weaken. It is recommended to try long positions on dips, and the main price fluctuation range may be between 8,000 - 9,500 yuan/ton [4]. Logs - The current main contract has switched to the 2511 contract, and the disk valuation fluctuates around the delivery cost and the receiving value range. There is an expectation of marginal improvement in the follow - up fundamentals. The demand is currently firm, maintaining at the level of 60,000 cubic meters. The inventory continues to decline due to less unloading at ports and strong outbound volume. It is expected that the overall shipment in September will be the same as that in August. The new warehouse receipts being registered may suppress the disk. It is recommended to go long on dips [6]. Glass and Soda Ash - **Soda Ash**: The impact of the coking coal event is gradually weakening, and the futures market continues to weaken. The weekly output has rebounded significantly, and the inventory is in a continuous pattern. The current weekly output corresponds to an obvious excess of demand. In the medium - term, after the photovoltaic rush installation in the second quarter, the growth of photovoltaic glass capacity has slowed down, and the float glass capacity has remained flat. There is still pressure on supply and demand in the future, and there may be further cold - repair expectations. Therefore, there is no growth expectation for the overall demand of soda ash. It is recommended to hold short positions [7]. - **Glass**: The impact of the coking coal event is gradually weakening, and the futures market continues to weaken. The middle - stream continuous shipment suppresses the spot price, and manufacturers are forced to cut prices. The market negative feedback continues. The near - month 09 contract has a weak reality, and the far - month 01 contract has a weak expectation. The deep - processing orders are weak, and the low - e glass production rate is continuously low. There is a certain pressure on the rigid demand side of glass. In the long - run, at the bottom of the real estate cycle, the completion volume is shrinking, and the industry needs capacity clearance to solve the over - supply dilemma. High - level short positions established earlier can be closed for profit, waiting for new logical drivers [7]. 3.

1. Report Industry Investment Rating - The overall mid - term outlook for the black building materials industry is "oscillation" [5]. - Specific varieties: iron ore, coke, coking coal, glass, soda ash, manganese silicon, and ferrosilicon are all rated as "oscillation" [6][7][10][11][13][15][16][17] 2. Core Viewpoints of the Report - The black price is in a weak oscillation. Although the demand is weakly expected in the peak season, the cost supply is disturbed, and there is a driving force for a rebound, but the upward space is limited. The follow - up should focus on policy implementation and terminal demand performance [5]. - After the decline of the glass futures and spot market sentiment, the supply is expected to be stable, and the short - term is expected to oscillate widely. The long - term price center will decline [13][14]. - The supply - surplus pattern of soda ash remains unchanged. The short - term is expected to oscillate widely, and the long - term price center will decline to promote capacity reduction [15]. 3. Summary by Related Catalogs 3.1 Iron Element (Iron Ore) - Supply: Overseas mine shipments decreased month - on - month, and the arrival volume at 45 ports slightly declined, close to the same period last year, with relatively stable total supply [2]. - Demand: The small - sample hot metal production decreased slightly, and the daily consumption of imported sinter decreased significantly. There is an expectation of a decline in hot metal production, but the impact is limited. After the parade, iron ore demand may return to a high level [2]. - Inventory: The iron ore port inventory decreased this week, and the total inventory slightly declined [2]. - Outlook: The fundamentals have limited negative driving forces, and the price is expected to oscillate [2][7]. 3.2 Carbon Element (Coking Coal and Coke) Coking Coal - Supply: Production in some mines is restricted, and coal mine safety inspections are increasing. Although the average daily customs clearance at the Ganqimao Port remains high, overall, coal mine production has tightened before the parade [2]. - Demand: The eighth round of coke price increase is restarted, and the demand for coking coal has slightly declined in the short term. Downstream purchases on demand, and some coal mines have inventory accumulation, but there is no obvious inventory pressure [2]. - Outlook: Before the parade, the coking coal market shows a pattern of weak supply and demand. Although it is difficult for the eighth round of coke price increase to be implemented, the futures market is still supported [11].

1. Report Industry Investment Rating - No information provided in the report regarding the industry investment rating. 2. Core Viewpoints of the Report - The overall atmosphere in the commodity market cooled yesterday, and the prices of finished steel products declined slightly. The weak demand pattern of finished steel is obvious, the profits of steel mills are gradually shrinking, and the weak characteristics of the market are becoming more prominent. If the subsequent demand cannot be effectively improved, the prices still face the risk of continuous decline. The raw material side is relatively more resilient than the finished steel products. It is recommended to continuously track the progress of terminal demand recovery and the support of the cost side for the prices of finished steel products [3]. - The supply of iron ore is in the traditional shipping off - season of overseas mines, and the pressure is not significant. The profitability of steel mills continues to decline, and the firm raw material prices have a certain impact on steel mill profits. The short - term increase in hot metal may be limited. The overall supply - demand contradiction of iron ore is not prominent for the time being, and the price is expected to fluctuate in the short term [6]. - The prices of ferroalloys have dropped rapidly, and the market is affected by emotions. In the short term, it is not recommended for speculative funds to participate excessively, while hedging funds can seize hedging opportunities according to their own situations. In the long run, prices will move closer to the fundamentals [10]. - The price of industrial silicon is expected to fluctuate, and the short - term operating range is 8300 - 9300 yuan/ton. The price of polysilicon may be adjusted in the short term, with support levels at 47000 and 44000 yuan/ton [15][16]. - Glass is expected to fluctuate weakly in the short term, and its valuation should not be overly underestimated. In the long term, it follows macro - sentiment fluctuations. The price of soda ash is expected to fluctuate in the short term, and the price center is expected to gradually rise in the long term, but the upward space is limited [18][19]. 3.
