1. Report Industry Investment Ratings No information is provided in the documents regarding industry investment ratings. 2. Core Views Glass and Soda Ash - The glass and soda ash futures markets continued to weaken yesterday. The soda ash market has an oversupply problem, and the inventory has transferred to the mid - downstream. There is no significant increase in downstream demand in the medium term. It is recommended to hold short positions. The glass spot market trading has become dull, and the industry needs capacity clearance to solve the oversupply problem. Track policies and the inventory - building performance of mid - downstream enterprises during the "Golden September and Silver October" [1]. Natural Rubber - Future supply increase expectations have weakened raw material prices, and the cost support has changed from strong to weak. The downstream tire factory's pre - holiday inventory replenishment is basically completed, and the de - stocking rhythm of natural rubber spot inventory has slowed down. Some enterprises may control production flexibly. Pay attention to the impact of typhoon weather on domestic production areas, and the 01 contract range is 15,000 - 16,500. Follow the raw material output in the main production areas during the peak season [3]. Logs - The log futures market fluctuated and closed flat. The inventory has decreased significantly, the demand has declined, and the supply is expected to increase. The market is in a volatile pattern. As the "Golden September and Silver October" approaches, pay attention to whether the shipment volume improves significantly during the seasonal peak season. It is recommended to go long at low prices [5]. Polysilicon - The polysilicon market continued to decline. Substantial support policies have not been implemented, and the industry's over - capacity pattern remains unchanged. The downstream component inventory is high, and prices are loosening. Follow national policies, the actual production start - up rate of polysilicon enterprises, and the inventory digestion progress of downstream photovoltaic component factories [6]. Industrial Silicon - From September to October, the supply of industrial silicon is increasing, and the market balance is gradually turning to looseness. The expected supply surplus is more obvious in October and narrows in November. The cost increase in the dry season in the southwest has boosted market sentiment. In the short term, the upward driving force of industrial silicon is insufficient, and the price may fluctuate between 8,000 - 9,500 yuan/ton. Pay attention to the production reduction rhythm of silicon material enterprises and industrial silicon enterprises in Sichuan and Yunnan in the fourth quarter [7]. 3.

1. Report Industry Investment Ratings No investment ratings are provided in the reports. 2. Core Views Glass and Soda Ash - Macro - warming and coking coal accident news drove the soda ash futures to rebound. Fundamentally, weekly production rebounded significantly, and the inventory continued to build up. With current weekly production, demand was significantly in excess. Recently, spot sales were weak. In the medium - term, after the second - quarter PV glass installation rush, PV glass capacity growth slowed, float glass capacity remained flat, and there was still pressure on supply - demand in the future, with potential for further cold - repair. Overall, there was no growth expectation for soda ash demand. Without actual capacity exit or load reduction, inventory would face more pressure. Track policy implementation and soda ash plant load adjustment [1]. Natural Rubber - Persistent rainy weather in internal and external production areas disrupted upstream supply, keeping raw material prices high. The de - stocking rate of spot inventory in Qingdao slowed, and with the incremental release of alternative plantings in Yunnan, China's social inventory increased, intensifying market bearish sentiment. In terms of demand, although agents' purchase volume might slightly increase at the end of the month to meet monthly targets, downstream buyers mainly continued regular restocking. Adverse external factors might slow down trading in the Beijing - Tianjin - Hebei region and potentially halt some mining and engineering operations, negatively affecting replacement demand. Affected by the Fed's dovish stance, market sentiment improved, driving up rubber prices, but prices were expected to fluctuate within a range. The reference range for the 01 contract was 15,000 - 16,500. Monitor raw material supply during the peak production season in major producing areas and consider short - selling if supply is smooth [3]. Polysilicon - In August, polysilicon supply and demand both increased, but the supply growth rate was higher, still facing inventory build - up pressure. Due to the previous sharp price increase above the full - cost level and the addition of two new delivery brands on the Guangzhou Futures Exchange, future warehouse receipts were expected to increase. Currently, the price would 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. Consider buying on dips. When the price is high, buy put options during low - volatility periods to short. Technically, the futures price might choose a direction to break out in a converging triangle, and consider buying straddle options when volatility is low. Pay attention to position control and risk management [5]. Industrial Silicon - From the cost side, raw material prices started to rise, and electricity prices in the southwest region would gradually increase during the dry season, raising the cost center of industrial silicon. Although industrial silicon production increased month - on - month, there were also news of capacity clearance, with small furnaces potentially shutting down. In August, supply and demand both increased, maintaining a tight balance. If some capacity is cleared in the long - term, supply pressure will ease. Strategically, consider buying on dips. However, note that as production increases, inventory and warehouse receipt pressure are emerging. The main price fluctuation range might be 8,000 - 9,500 yuan/ton, and hold long positions established at the previous low of 8,000 - 8,500 [6]. 3.

1. Report Industry Investment Ratings - No industry investment ratings are provided in the reports. 2. Core Views Glass and Soda Ash - In the context of macro - warming and driven by news of coking coal accidents, the soda ash futures market rebounded. Fundamentally, weekly production increased significantly, but the demand was obviously in excess under the current weekly production. In the medium - term, after the second - quarter rush for photovoltaic installation, the growth of photovoltaic glass capacity slowed down, and the float glass capacity remained flat. There is still pressure on supply and demand in the future, and there may be further cold - repair expectations. Without actual capacity withdrawal or load reduction, the inventory will be further pressured. Attention should be paid to the implementation of policies and the load - regulation of soda ash plants [1]. Natural Rubber - Due to continuous rainy weather in both domestic and foreign production areas, upstream supply fell short of expectations, and raw material prices remained high. The de - stocking rate of spot inventory in Qingdao slowed down, and with the incremental release of alternative plantings in Yunnan, China's social inventory increased, intensifying the market's bearish sentiment. In terms of demand, although agents may slightly increase their purchases to meet monthly tasks at the end of the month, downstream demand mainly continues with regular replenishment. Affected by external factors, trading in the Beijing - Tianjin - Hebei region may slow down, and mining and engineering operations in some other regions may be suspended, which is negative for the replacement demand. Overall, affected by the dovish stance of the Federal Reserve, market sentiment improved, driving up rubber prices, but rubber prices are expected to fluctuate within a range. The reference range for the 01 contract is 15,000 - 16,500. Follow - up attention should be paid to the raw material supply during the peak production season in the main production areas, and short positions can be considered if the raw material supply goes smoothly [3]. Polysilicon - In August, both supply and demand of polysilicon increased, but the supply growth rate was relatively large, and there was still pressure on inventory accumulation. Due to the previous sharp rise in prices above the full - cost level and the addition of two new delivery brands by the Guangzhou Futures Exchange, it is expected that the number of warehouse receipts will further increase. Currently, attention can be paid to the constraints of energy consumption and green - electricity ratio in promoting the orderly exit of backward production capacity. 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 possibly between 58,000 - 60,000 yuan/ton. It is recommended to try long positions on dips. When the price is high, put options can be bought during low - volatility periods to try short positions. Technically, the futures price may choose a direction to break through in a converging triangle, and straddle options can be bought when the volatility is low. Investors are advised to pay attention to position control and risk management in advance [5]. Industrial Silicon - From the cost perspective, raw material prices started to rise, and the electricity price in the southwest region will gradually increase during the dry season, causing the cost center of industrial silicon to rise. Although the production of industrial silicon increased month - on - month recently, there were also news of production - capacity clearance, and small furnaces may be shut down. In terms of supply and demand, both supply and demand increased in August, maintaining a tight balance. If some production capacity is cleared in the long - term, the supply pressure will be reduced. It is recommended to try long positions on dips. However, it should be noted that as production increases, inventory and warehouse - receipt pressure are emerging. The main price fluctuation range is expected to be between 8,000 - 9,500 yuan/ton, and long positions established at the previous low level of 8,000 - 8,500 yuan/ton should be held [6]. Logs - No overall core view is explicitly stated in the log report, but data on price, supply, inventory, and demand are presented. 3.
