Report Industry Investment Rating No relevant content provided. Core Views - The steel market is currently focused on the Fourth Plenary Session. Steel prices may experience a slight rebound, but the weak fundamentals limit the upside potential, and a subsequent decline is likely. Short - term outlook is for a rebound, while the medium - to - long - term remains weak [3]. - The iron ore market is operating weakly under macro - sentiment and fundamental pressures. The supply is strong, and demand is weak. The price may be supported if there are positive policy signals [18]. - The coking coal market has strong bottom support due to tight resources and policy expectations, but the rebound space is limited by downstream contradictions. The price rebound depends on the downstream steel supply - demand balance [30]. - The ferroalloy market is under pressure due to weak downstream demand and high inventory. Without unexpected stimulus policies, prices will remain under pressure [48]. - The soda ash market has supply pressure in the long - term. Although exports are better than expected, high inventory restricts the price, with limited downside due to cost support [61]. - The glass market has weak demand and high inventory, and prices are suppressed. The implementation of the coal - to - gas project in Shahe and production line ignition plans need to be monitored [86].

1. Report Industry Investment Rating - The report gives a "neutral" rating to the black building materials industry, with the overall outlook being "sideways" [2][3] 2. Core Viewpoints of the Report - The fundamentals of the black building materials sector were generally stable yesterday, but steel and iron ore prices on the futures market continued to face pressure, dragging down coal and coke products. As the traditional off - season approaches, the actual demand for steel is unlikely to improve significantly. With the approaching of the blast furnace maintenance season for steel enterprises, there are still expectations of negative feedback in the industrial chain. However, in late October, the expectation of positive news from domestic and foreign macro - level meetings has increased, and short - term sector varieties are expected to remain volatile. Attention can be paid to the rebound opportunities under the background of policy introduction [2][3] 3. Summary by Category 3.1 Iron Element - Iron ore: The fundamentals of iron ore have slightly weakened at the margin, but the overall pressure is not prominent. With the still - existing macro - level expectation disturbances, a slight recovery in steel demand, and uncertainties in Sino - US trade relations, the short - term price of iron ore is expected to fluctuate within a range. - Scrap steel: The contradictions in the scrap steel market are not prominent. With the current pressure on finished steel prices and poor EAF profits, the short - term price of scrap steel is expected to follow the trend of finished steel [2] 3.2 Carbon Element - Coke: In the short term, the supply and demand of coke are tight. With the deterioration of coking profits, the second - round price increase has been initiated. However, steel mills' profits are also poor, and the game between coking plants and steel mills continues. Whether the price increase can be implemented remains to be seen. The price of coke is expected to fluctuate. - Coking coal: Under the background of "anti - involution" and over - production inspections, the release of supply - side production capacity is restricted. The demand side still has rigid demand support from short - term coke production. With low inventories upstream, the fundamentals are relatively healthy. The price of coking coal is expected to fluctuate [2] 3.3 Alloys - Manganese silicon: Cost, high steel production, and macro - policy expectations support the price of manganese silicon, but the market's supply - demand expectation is pessimistic, and the medium - to - long - term price center may still decline. - Ferrosilicon: Ferrosilicon is also supported by high finished steel production, policy expectations, and cost. However, the supply - demand relationship is becoming looser, and the price still faces downward pressure in the later stage [2] 3.4 Glass and Soda Ash - Glass: The spot sales of glass are weak. After the synchronous decline of the spot and futures markets, the short - term price fluctuates weakly. Currently, the middle - stream has not significantly reduced inventory, and there is little chance of a short - term rebound. In the long - term, market - based capacity reduction is still needed. If the market refocuses on fundamentals, the price may continue to decline. - Soda ash: The pattern of over - supply in the soda ash market remains unchanged. It is expected to fluctuate widely following macro - level changes in the future, and the long - term price center will still decline to promote capacity reduction [3] 3.5 Specific Product Analysis - Steel: The recovery of post - holiday demand is limited, and steel inventories are at a moderately high level. Fundamental contradictions still exist, and the upper limit of the futures price is suppressed. With important domestic meetings this week, attention should be paid to policy - related disturbances. The short - term futures price is expected to fluctuate at a low level [7] - Iron ore: The short - term price is expected to fluctuate due to marginal weakening of fundamentals, macro - level disturbances, and uncertainties in Sino - US trade relations [7] - Scrap steel: With its own fundamentals having no prominent contradictions, the short - term price is expected to follow the trend of finished steel due to pressure on finished steel prices and poor EAF profits [9] - Coke: In the short term, the supply and demand of coke remain tight. With the continuous deterioration of coking profits, the second - round price increase has been initiated, but it still needs time to be implemented. The price is expected to fluctuate [11] - Coking coal: With supply still restricted and good auction results, the price is expected to fluctuate [10][11] - Glass: The spot sales are weak, and the short - term price fluctuates weakly. There is little chance of a short - term rebound. In the long - term, it is expected to decline if the market focuses on fundamentals [12] - Soda ash: The over - supply pattern remains unchanged. It is expected to fluctuate widely following macro - level changes, and the long - term price center will decline [14] - Manganese silicon: Cost, high steel production, and macro - policy expectations support the price, but the market's supply - demand expectation is pessimistic, and the price center may decline [14][15] - Ferrosilicon: Although supported by high finished steel production, policy expectations, and cost, the supply - demand relationship is becoming looser, and the price still faces downward pressure [16] 3.6 Index Information - Comprehensive Index: The commodity index was 2239.21, up 0.35%; the commodity 20 index was 2544.06, up 0.41%; the industrial products index was 2185.29, up 0.06%; the PPI commodity index was 1323.60, up 0.10%. - Plate Index: The steel industry chain index on October 21, 2025, was 1968.47, with a daily decline of 0.39%, a 5 - day increase of 0.42%, a 1 - month decline of 2.87%, and a decline of 6.63% since the beginning of the year [102][103]

Report Industry Investment Ratings - No industry investment ratings are provided in the reports. Core Views Industrial Silicon - Industrial silicon spot prices are stable, while futures prices fluctuate and closed down 60 yuan/ton to 8,505 yuan/ton. September's export volume decreased by 8% month-on-month to 70,200 tons but remained year-on-year growth. In October, the supply of industrial silicon increased significantly, with a risk of inventory accumulation and price pressure. Although some enterprises in the southwest region reduced production, the impact on output was small, and the supply side still increased due to the increase in Xinjiang's output. Considering the potential increase in raw material costs such as coal prices and the rise in electricity prices in November, the future price center is expected to move up. Currently, the price is expected to fluctuate at a low level, mainly in the range of 8,000 - 9,000 yuan/ton. If the price of the 11 - contract falls to the low level of 8,000 - 8,300 yuan/ton, one can consider buying on dips [1]. Polysilicon - The spot price of polysilicon rose by 0.2 yuan/kg to 53 yuan/kg, and the futures price fluctuated and slightly rebounded by 375 yuan/ton to 50,715 yuan/ton, with futures at a discount. On the demand side, the output of silicon wafers increased significantly, and the demand for battery wafers was supported by overseas purchases driven by India's ALMM policy and the demand for high - efficiency wafers in domestic centralized projects. It is highly likely that the output will increase in October. Whether the demand can absorb the increased output during the fourth - quarter rush installation and the increase in export orders will have a significant impact on prices. Currently, the polysilicon market is relatively stable. One should pay attention to policy implementation, production control, and whether there is an increase in demand orders. In the future, the supply in the southwest region will decrease during the dry season, which will support prices, but one should guard against the risk of inventory accumulation due to lower - than - expected demand [2]. Glass and Soda Ash - Soda ash continues to weaken, with manufacturers' inventories and mid - stream delivery inventories increasing, highlighting the surplus. The weekly output is at a high level, and the surplus is obvious compared with the current rigid demand. Most of the inventory has been transferred to the mid - and downstream, and the trade inventory continues to rise. In the medium term, there is no expectation of a significant increase in downstream production capacity, so the overall demand for soda ash will continue the previous rigid - demand pattern. If there is no actual production capacity exit or load reduction, the supply - demand situation will be further pressured. One can track macro fluctuations and the load - control situation of soda ash plants. The overall supply - demand pattern is bearish, and the operation idea is to short on rebounds [4]. - Glass manufacturers' sales are average, and they continue to cut prices. Hubei's price is basically at par with the futures market. In recent days, the futures market has continued to weaken, trading on the logic of a non - prosperous peak season and fundamental surplus. In addition, the mid - stream inventory in some regions remains high without obvious destocking. In terms of industry supply - demand, although the deep - processing orders have improved seasonally, they are still weak, and the LOW - E开工率 remains low without obvious peak - season characteristics. In the long - term, the real - estate cycle is at the bottom, and the industry needs to clear production capacity to solve the surplus problem. Currently, the futures market has been trading on the non - prosperous peak - season logic. In the medium term, one should pay attention to the spot trading rhythm, high - frequency data changes, and macro - level drivers [4]. Natural Rubber - On the supply side, the prices of overseas raw materials have been firm recently, and the significant destocking of dark - colored rubber still provides cost support for rubber prices. However, there is a strong expectation that the weather in northeastern Thailand will improve, and the raw material prices are expected to weaken. One should pay attention to future weather conditions. On the demand side, after the "Double Festival" holiday, most of the enterprises that had maintenance have resumed normal production, but the overall market has not shown obvious improvement. To control inventory growth, some enterprises are still in a state of flexible production control. It is expected that the enterprise equipment will operate stably in the short term, adjusting production according to their own orders. In summary, the short - term macro - environment has improved, and the rubber price has rebounded due to the improvement in fundamentals. One should pay attention to the raw material output in the peak - production season of the main producing areas and macro - level changes. If the raw material supply is smooth, the rubber price may decline further; if not, the rubber price is expected to operate around 15,000 - 15,500 [5]. Logs - The log futures fluctuated yesterday, with the 2601 contract closing at 838 yuan/cubic meter, up 3.5 yuan from the previous day. The spot prices of the main benchmark delivery products remained unchanged, with the price of 3.9 - meter medium - A radiata pine in Shandong being 760 yuan/cubic meter and that in Jiangsu being 780 yuan/cubic meter. Last week, the inventory decreased. As of October 17, the total inventory of coniferous logs in the country was 2.92 million cubic meters, a decrease of 70,000 cubic meters from the previous week. On the demand side, the outbound volume increased. As of October 17, the daily average outbound volume of logs was 63,200 cubic meters, an increase of 5,900 cubic meters from the previous week. On the supply side, this week, 12 New Zealand log ships are expected to arrive at 13 Chinese ports, an increase of 0 from the previous week; the total arrival volume is about 438,000 cubic meters, an increase of 20,000 cubic meters from the previous week, a week - on - week increase of 5%. Currently, there is no obvious driving force in the supply - demand of logs. The 01 contract is relatively strong. The new round of overseas quotes has increased, and the subsequent port fees are expected to rise, providing strong cost support. During the seasonal peak season, there is some support below the futures price, and the 01 contract may be strong [6].
