Report Information - Report Name: Soda Ash, Glass Daily Report [1] - Date: November 7, 2025 [2] - Research Team: Energy and Chemical Research Team [4] Industry Investment Rating - No relevant information provided. Core Viewpoints - Soda ash supply remains high with a slight decline in开工率 and a marginal increase in inventory. The downstream market mainly replenishes inventory at low prices, and the supply - demand weakness in the glass market persists. In winter, there is insufficient driving force in the supply - demand aspect of soda ash, and the pattern of oversupply may continue. The soda ash futures market is expected to maintain a volatile trend [8]. - The glass market is at a high level of supply this year. After the festival, the factory inventory remains high, and the demand recovery is weak. Although the production limit in Shahe has been implemented, the actual situation is not as expected. With the arrival of the off - season, there is no new driving force in the market. The short - term bullish sentiment from the Shahe production halt has been digested. The glass futures market is expected to be volatile in the near term, and the downward trend may be difficult to reverse in the medium term without new market expectations [9]. Summary by Section I. Soda Ash, Glass Market Review and Operation Suggestions Soda Ash - On November 6, the main soda ash futures contract SA601 showed a volatile and slightly stronger trend, closing at 1,207 yuan/ton, up 10 yuan/ton or 0.83%, with a daily reduction of 31,271 lots [8]. - Fundamentally, enterprise production and sales tend to balance, and inventory fluctuates little. Weekly soda ash production decreased 1.41% to 74.69 tons, remaining at a high level. The soda ash production facilities operate stably, and individual maintenance has little impact [8]. - In early November, the shipment of Chinese soda ash enterprises decreased, with a total shipment of 73.39 tons, a 3.14% decrease. The production of float glass decreased slightly, and the production of photovoltaic glass remained basically unchanged with inventory accumulation, so the subsequent demand for heavy soda ash may further decline [8]. - The inventory of soda ash plants fluctuated slightly, rising to 171.42 tons, in the median range of the past six months [8]. Glass - Fundamentally, four coal - fired production lines in Shahe will be shut down in the short term. The photovoltaic glass market is in a weak balance, and the overall glass supply is at a high level this year [9]. - After the festival, the factory inventory remains high, and the inventory days have continuously increased. The real estate market has not shown a stable trend, the completion data is weak, and the recovery of float glass demand may not be sustainable [9]. II. Data Overview - The report provides multiple data charts, including the price trends of active soda ash and glass contracts, weekly soda ash production, soda ash enterprise inventory, the market price of heavy soda ash in Central China, and flat glass production [12][14][17]

1. Report Industry Investment Ratings - There is no information about industry investment ratings in the provided content. 2. Core Views of the Report - The glass market is in a situation where the supply - demand contradiction is large, with high inventory levels. Although there is some de - stocking, the long - term demand is not optimistic due to the approaching end of the consumption peak season and the sluggish real - estate industry. The price is expected to be in a weak and volatile state [1][2]. - The纯碱 market also has supply - demand contradictions. High inventory continues to suppress prices, and there is a pressure to reduce inventory throughout the year. The price is expected to be in a weak and volatile state [1][2]. - In the silicon - manganese market, the supply - side pressure has eased, but the inventory is still accumulating, and the price is expected to fluctuate with the black - goods sector in the long run [3][4]. - In the silicon - iron market, there is a pattern of high production, high inventory, and weak demand. The weak fundamental situation is difficult to reverse, and the price is expected to follow the sector in the short term [3][4]. 3. Summary by Related Catalogs Glass and Soda Ash Market Analysis - Glass: The glass futures market oscillated, and the spot price was stable with mainly rigid - demand purchases. This week, the float - glass enterprise operating rate was 75.92%, a 0.43% decrease from the previous week, and the factory inventory was 63.136 million heavy cases, a 4.03% decrease [1]. - Soda Ash: The soda - ash futures market oscillated upwards, and the downstream mainly replenished inventory at low prices. This week, the soda - ash output was 746,900 tons, a 1.41% decrease, and the inventory was 1.7142 million tons, a 0.72% increase [1]. Supply - Demand and Logic - Glass: The supply - demand contradiction is large.

Report Industry Investment Rating No relevant content provided. Core Viewpoints of the Report - The overall atmosphere in the commodity market was weak yesterday, with finished steel prices showing a weak and volatile trend. Although the steel demand has officially entered the off - season and there is a risk of inventory accumulation for hot - rolled coils, with the implementation of the Fed's easing expectations and positive signals from the China - US meeting, the market sentiment and capital environment are expected to improve, and the steel consumption end may gradually recover in the future [2]. - For iron ore, the supply is still at a high level in the same period, but the demand continues to weaken, and the inventory pressure remains. After the macro - events are realized, the fundamentals of iron ore are weak, and the price is expected to be weak and volatile in the short term. If the US liquidity problem is alleviated, the price may stabilize [5]. - Regarding manganese silicon and silicon iron, the fundamentals are not ideal, and they are likely to follow the trend of the black sector. The operability is relatively low [10]. - For industrial silicon, the supply pressure persists, and the demand support weakens. The price is likely to fluctuate with the commodity market in the short term, and attention should be paid to the option game near the expiration [13]. - For polysilicon, the supply - demand pattern may improve marginally, but the short - term inventory reduction is limited. The market has strong expectations for the industry meeting, and the price is highly volatile [16]. - For glass, the market expects an improvement in the supply structure, but the price increase is restricted by the low procurement enthusiasm of downstream factories. The sustainability of the market depends on spot transactions and inventory reduction [19]. - For soda ash, the industry operating rate remains high, the loss continues to expand, and the demand is mainly for rigid restocking. The price is expected to continue the weak and volatile pattern in the short term [21].

The sustainability of the market depends on spot transactions and inventory reduction [19]. - Soda ash: The industry operating rate remains high, the loss continues to expand, and the demand is mainly for rigid restocking. The price is expected to continue the weak and volatile pattern in the short term [21].

Group 1: Investment Ratings - There is no information about the industry investment ratings in the provided reports. Group 2: Core Views Rubber Industry - Dark - colored rubber has reached an inventory accumulation inflection point, market sentiment is weak, and rubber prices have further declined. If raw material supply is smooth during the peak production season in the main producing areas, there is room for further decline; if not, the rubber price is expected to fluctuate between 15,000 - 15,500 yuan/ton [1]. Glass and Soda Ash Industry - Soda ash prices are trending weakly, with over - supply prominent. The market is under pressure, and the overall demand will continue the previous rigid pattern. Operationally, it should be treated bearishly. For glass, although there is a demand expectation during the peak season in November, in the long - term, the industry needs capacity clearance, and short - term long opportunities can be captured when prices rebound from lows [3]. Industrial Silicon Industry - Industrial silicon spot prices are stable, while futures prices are oscillating downward. In November, there is still inventory accumulation pressure. The price is expected to oscillate at a low level, mainly in the range of 8,500 - 9,500 yuan/ton. When the price drops to around 8,500 yuan/ton, one can consider going long [4]. Polysilicon Industry - Polysilicon spot prices have fallen, and futures prices have dropped significantly. In November, the supply and demand are both weak, and there is still inventory accumulation pressure. The price is expected to oscillate in a high - level range. Different trading strategies are proposed for futures, options, and equities [5]. Log Industry - Log futures are oscillating weakly. The supply is increasing, but downstream orders are insufficient, and the market is under pressure. However, the price difference between domestic and foreign markets provides some support. The log futures are expected to continue to oscillate weakly [7].

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].
