1. Report Industry Investment Rating - The report does not explicitly mention an overall industry investment rating. However, it provides individual outlooks for different commodities in the black building materials sector, mostly indicating a "震荡" (sideways) trend, suggesting a neutral stance for the short - term investment in general [2][10][13]. 2. Core Viewpoints - The fundamentals of the black building materials sector are generally stable. Without macro and policy boosts, the sector's prices are oscillating weakly. The glass with supply - side disturbances showed relatively strong price performance this week. The reduction in hot metal in the industry chain is due to seasonal characteristics and production - limiting measures, having limited negative impact on furnace material demand. When macro and policy levels release positive signals, it will support the prices of sector commodities [1][2]. 3. Summary by Commodity Iron Element - **Iron Ore**: There is an expectation of inventory accumulation, but the decline in ore prices is limited. With macro and policy uncertainties, short - term prices are expected to oscillate. The fundamentals of scrap steel have no prominent contradictions, and its price is expected to follow that of finished products as the latter is under short - term pressure [2]. - **Scrap Steel**: The fundamentals have no significant contradictions. With short - term pressure on finished product prices, scrap steel prices are expected to follow finished products [2][9]. Carbon Element - **Coke**: After three rounds of price increases, the profit pressure on steel mills is high, so the expectation of a fourth - round increase is low. Given strong cost support, the price is expected to oscillate [2]. - **Coking Coal**: Supply is hard to improve. With continuous procurement from the middle and lower reaches, coal mine inventories have reached multi - year lows. The short - term fundamentals are healthy, and the price is expected to oscillate [2][12]. Alloys - **Manganese Silicon**: Short - term cost stability and high steel production support its price, but the market has a pessimistic supply - demand outlook, and the driving force for price increases is insufficient [2]. - **Silicon Ferrosilicon**: High steel production and rising costs support its price, but the loose supply - demand relationship restricts the upside [2][15]. Glass and Soda Ash - **Glass**: Supply is expected to be disturbed in the short - term, facing a downward risk. With medium and downstream inventories at a moderately high level, if production and sales remain weak, the price will return to a weak oscillation. In the long - term, market - based capacity reduction is needed, and the price may continue to decline [3][13]. - **Soda Ash**: The supply surplus situation is intensifying. Cost supports the price bottom, and the price will oscillate in the short - term. In the long - term, the price center will decline to promote capacity reduction [3][13]. Steel - The fundamentals have limited support, and the futures market is running weakly. Spot market transactions are generally weak, and speculative sentiment is poor. Although steel mill profits have improved marginally, hot metal production has decreased from a high level due to environmental protection and seasonal maintenance. The output of five major steel products has increased, and demand has continued to recover. Steel inventories have continued to decline, but the year - on - year high inventory level remains unchanged. With the approaching end of the peak season, the demand outlook is still cautious, and the futures market is expected to face pressure after the cooling of macro sentiment [8]. Others - **Base Difference Seasonal Charts**: Include steel, iron ore, coking coal, coke, silicon ferrosilicon, silicon manganese, glass, and soda ash base differences [20][23][25]. - **Profit Seasonal Charts**: The report mentions profit seasonal charts but does not provide specific content [62]. - **Steel Daily Transactions**: The report mentions steel daily transactions but does not provide detailed content [82]. - **Commodity Index**: On November 4, 2025, the comprehensive index was 2229.67, down 0.92%; the commodity 20 index was 2521.83, down 0.98%; the industrial product index was 2213.57, down 1.07%. The steel industry chain index on November 4, 2025, was 1997.33, with a daily decline of 1.24%, a 5 - day decline of 3.03%, a 1 - month increase of 0.37%, and a year - to - date decline of 5.26% [98][100].

Report Industry Investment Ratings - No industry investment ratings are provided in the reports. Core Views Industrial Silicon - Industrial silicon spot prices are stable, and futures prices fluctuate and rise after opening low. In November, the industrial silicon market still faces inventory accumulation pressure. Although supply may decline slightly and demand may remain stable, the increase in supply in the spot market may lead to inventory accumulation and put pressure on spot prices. However, there is cost - side support. It is expected to fluctuate at a low level, mainly in the range of 8500 - 9500 yuan/ton. Consider buying on dips when the price drops to around 8500 yuan/ton [1]. Polysilicon - Polysilicon spot prices are stable, and futures prices fluctuate and decline. Currently, futures are at a premium to the spot average. In November, supply pressure decreases, but demand also drops. The overall supply - demand is weak, and there is still inventory accumulation pressure. It is expected to fluctuate in a high - level range. Futures can be bought on dips near the lower edge of the range; options can sell put options around 50000 to earn premiums; the equity side can buy photovoltaic ETFs, new energy ETFs, or related stocks [2]. Glass and Soda Ash - Soda ash prices are weakly volatile, with low demand and obvious excess. The market is under pressure. In the medium - term, downstream demand will maintain the previous rigid - demand pattern. The supply - demand pattern is still bearish, and short - selling opportunities on rebounds can be considered. For glass, the news of production line shutdown in Shahe has a short - term emotional impact on the market, but in the long - term, there will be production line restarts, which will put pressure on supply. The deep - processing orders are seasonally weak, and the low - e开工率 is low. In November, there is still some peak - season demand expectation. Pay attention to the demand performance after price cuts. In the long - term, the glass industry needs capacity clearance. Short - term long - buying opportunities on rebounds can be grasped [4]. Logs - Log futures fluctuate. The main benchmark delivery product spot prices are unchanged. Last week, inventory increased slightly, and demand decreased slightly. The supply of arriving ships is increasing. The market is under pressure, but the price difference between domestic and foreign markets provides some support. Log futures are expected to maintain a weak - volatile trend [5]. Natural Rubber - In the short - term, cost - side supports rubber prices due to rainfall affecting rubber tapping. In the long - term, there is an expectation of increased supply. Demand is weak at the beginning of the month, and the replacement demand for all - steel tires in the north will further weaken. Dark - colored rubber has shown an inventory accumulation inflection point, and rubber prices may decline further. If raw material supply is smooth, there is room for further decline; if not, the price may run around 15000 - 15500 [7].

1. Report Industry Investment Ratings No information about industry investment ratings is provided in the reports. 2. Core Views Industrial Silicon - Industrial silicon spot prices are stable, and futures prices rebounded after opening low. In November, the market still faces inventory accumulation pressure. Prices are expected to fluctuate at a low level, mainly in the range of 8,500 - 9,500 yuan/ton. Consider buying on dips when prices fall to around 8,500 yuan/ton. Pay attention to the digestion of warehouse receipts after the centralized cancellation of November contracts [1]. Polysilicon - Polysilicon spot prices are stable, and futures prices are oscillating downward. In November, the supply pressure decreases, but the demand also declines. The market is expected to oscillate in a high - level range. Futures can be bought on dips when prices return to the lower end of the range. Options can sell put options around 50,000 to earn premiums. For the equity side, buy photovoltaic ETFs, new energy ETFs, or related stocks. Also, pay attention to the digestion of warehouse receipts after the centralized cancellation of November contracts [2]. Glass and Soda Ash - Soda ash prices are weakly oscillating, with low demand and obvious oversupply. The market is bearish in the long - term. Consider short - selling on rebounds. For glass, there is a short - term emotional impact on the market, and mid - to long - term supply pressure remains. In November, there is still a demand expectation during the peak season. Pay attention to the demand performance after price cuts. Look for short - term long opportunities on rebounds [4]. Logs - Log futures prices are oscillating weakly. Although the supply of arrivals is increasing, downstream orders are insufficient, and the market is under pressure. However, the inverted price between domestic and foreign markets provides cost support. The futures market is expected to continue to oscillate weakly [5]. Natural Rubber - In the short term, the cost side strongly supports rubber prices due to rainfall affecting rubber tapping. In the long term, there is an expectation of increased supply. Demand is weakening, and dark - colored rubber has shown an inflection point in inventory accumulation. If raw material supply increases smoothly, rubber prices may decline further, with a possible range of 15,000 - 15,500 yuan/ton [7]. 3.
