基本?驱动有限，政策预期仍有扰动

Report Industry Investment Rating - The overall mid - term outlook for the black building materials sector is "oscillation" [6]. Core Viewpoints of the Report - In October, the poor industry demand and the maintenance of high molten iron levels continue to lead the prices of black building materials sector varieties to oscillate. Considering the limited changes in fundamentals and the increasing domestic and foreign macro and policy expectations, attention should be paid to the subsequent internal and external policy disturbances [6]. Summary by Variety Steel - Logic: Cost is strong, and there are still positive signals from the policy end, leading to a slight increase in the futures market. The spot market transactions are average, with some post - holiday demand release. The blast furnace profit is average, and the molten iron output remains high. The electric furnace profit has slightly improved, and the production resumption enthusiasm of electric furnace steel mills has increased. The inventory of the five major steel products has accumulated significantly, and the inventory accumulation speed during the holiday is faster than in previous years, putting pressure on the fundamentals [7]. - Outlook: The rapid inventory accumulation of steel during the holiday has put pressure on the fundamentals. However, the molten iron output is at a relatively high level, there are continuous disturbances on the supply side of furnace materials, and the cost support is strong. The macro - environment is warm, and it is expected that the futures market will have strong support below in the short term [7]. Iron Ore - Logic: Overseas mine shipments have decreased slightly, and the arrival volume at 45 ports has increased, with overall stable supply. The average daily output of molten iron has slightly decreased, but it is still at a high level, providing rigid demand support. The steel mill inventory has decreased significantly during the holiday, and some steel mills have restocking plans after the holiday, leading to a significant recovery in spot transactions. The port inventory has increased slightly, and the overall inventory pressure is not prominent [8]. - Outlook: The demand for iron ore is supported at a high level, and the supply is generally stable. There are still macro - expectations disturbances before important meetings, but the general performance of the building materials peak season demand restricts the upward space of iron ore. It is expected that the short - term price will oscillate [8]. Scrap Steel - Logic: After the holiday, the arrival volume of scrap steel at steel mills is low, and the daily consumption has decreased. The price of finished products is under pressure, and the electric furnace profit is poor. The steel enterprises mainly consume inventory during the holiday, and the inventory has decreased slightly [9]. - Outlook: The supply and demand of scrap steel have both decreased, and the price has slightly declined on the first day after the holiday. The scrap steel's own fundamental driving force is insufficient, and it is expected that the short - term price will follow the finished products [9]. Coke - Logic: On the futures side, funds flowed out before the holiday, and the market rebounded after the holiday. On the spot side, the quotation has decreased. The loss of coke enterprises has slightly improved, but the high raw coal price restricts the overall start - up of coke enterprises, and the supply has slightly decreased. The blast furnace maintenance of steel mills has increased, and the molten iron output has slightly decreased but is still at a high level, providing rigid demand support. The steel mills have completed restocking and are purchasing on demand, and the upstream inventory is still at a low level [11]. - Outlook: In the short term after the holiday, the molten iron output will remain high, providing rigid demand support. The coking profit has slightly improved but still restricts the supply increase. The fundamentals are healthy in the short term. With the strengthening of macro - positive expectations, it is expected that the coke price will remain stable in the future [11]. Coking Coal - Logic: On the futures side, there were many positive news on the first day after the holiday, and the market sentiment was warm. On the spot side, the price remained unchanged. The supply of some domestic mines decreased during the holiday, and the import of Mongolian coal was restricted during the holiday but is expected to increase in the future. The demand for coking coal is still supported by the high - level coke production, and the upstream inventory is at a low level [11]. - Outlook: After the holiday, coal mine production will recover quickly, and the import of Mongolian coal is expected to reach a high level, with a strong expectation of supply increase. However, the supply increase will be restricted by factors such as "anti - involution" and safety supervision. The demand for coking coal is still supported by the high - level coke production in the short term. The macro - environment is warm, and it is expected that the price will oscillate in the future [12]. Glass - Logic: The national average price has increased slightly. The "anti - involution" expectation still has an impact, and the macro - environment is neutral to strong. The "Stability and Growth Plan for the Building Materials Industry" will optimize the supply of float glass in the long term. The demand is in the peak season, but the mid - stream inventory is large, and the downstream inventory is neutral, with limited restocking ability. There are concerns about supply disturbances in the Shahe area, and the inventory has accumulated significantly during the National Day. If the supply disturbance expectation does not materialize, the price may be under pressure again [12]. - Outlook: A large amount of inventory has accumulated during the National Day. After the holiday, manufacturers try to raise prices to boost restocking sentiment. If the post - holiday production and sales are good and the spot price increase is implemented, the futures market will have room for a certain rebound. Otherwise, the fundamentals may suppress the futures and spot prices again. 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 [13]. Soda Ash - Logic: The price of heavy soda ash has decreased. The "anti - involution" expectation still has an impact, and the macro - environment is neutral to strong. The production capacity has not been cleared, and there is long - term suppression. The output has decreased due to some manufacturers' sudden maintenance. The demand for heavy soda ash is expected to maintain rigid procurement, and the demand for light soda ash has increased. The market transaction was weak during the National Day, and the supply - demand fundamentals have not changed significantly. It is expected that the upstream inventory will increase this week, and the industry is still in the stage of capacity clearance at the bottom of the cycle, with the price expected to oscillate weakly [16]. - Outlook: The oversupply pattern has not changed. It is expected that the price will oscillate widely following macro - changes in the future. In the long - term, the price center will continue to decline to promote capacity reduction [16]. Manganese Silicon - Logic: After the holiday, the black sector was strong, but the manganese silicon futures market oscillated due to weak fundamentals. The spot market sentiment was cautious, and the price remained stable. The manganese ore market inquiry was cold, and the port inventory has accumulated during the holiday. The manganese silicon manufacturers' profit is poor, and there is a sentiment of price - pressing procurement. The steel mills' demand for manganese silicon is still resilient, but the market supply pressure is gradually increasing, and the future inventory clearance will be more difficult [17]. - Outlook: In the short term, the cost and peak - season demand support the price, but the market supply - demand expectation is pessimistic. After the peak season, the price center of manganese silicon still has downward space. Attention should be paid to the reduction range of raw material costs [17]. Ferrosilicon - Logic: The prices of black chain varieties were strong, but the ferrosilicon futures market was weak due to the reduction of the settlement electricity price in the main production areas in September. The spot market transaction atmosphere was average, and the manufacturers' quotations were gradually loosening. The ferrosilicon production remains at a high level, and the market supply pressure is gradually increasing. The demand from steel mills is still supported, but the demand for magnesium ingots is weak, suppressing the price [18]. - Outlook: In the short term, the peak - season demand and cost support the ferrosilicon price, but the market supply - demand relationship is becoming looser. After the peak season, the price still has downward pressure. Attention should be paid to the reduction of electricity costs in the main production areas [18].
