Group 1: Polysilicon Report Industry Investment Rating - Not mentioned Core View - The substantial support policies such as "anti - involution" in the polysilicon market have not been implemented in time, and the new energy - consumption national standard has limited impact on short - term supply and demand. The supply - side regulation effect is less than expected, and the industry's over - capacity pattern remains unchanged. The inventory of downstream component links is high, and prices are loosening. Future attention should be paid to national - level policies on capacity clearance and industry procurement, as well as the actual start - up rate and production reduction implementation of polysilicon enterprises, and the inventory digestion progress and new order demand of downstream photovoltaic component factories [1]. Summary by Directory - **Spot Price and Basis**: The average price of N - type polysilicon materials remained stable on September 22 compared with September 19, while the N - type material basis (average price) increased by 3420.00% [1]. - **Futures Price and Inter - month Spread**: The main contract price decreased by 3.24% from September 19 to September 22, and the spread between different months showed various changes [1]. - **Fundamental Data**: Weekly polysilicon production decreased by 0.64%, while monthly production increased by 23.31%. Monthly polysilicon import decreased by 9.63%, and net export increased by 94.25%. Weekly and monthly silicon wafer production increased [1]. - **Inventory Change**: Polysilicon inventory decreased by 6.85%, and silicon wafer inventory increased by 1.93% [1]. Group 2: Industrial Silicon Report Industry Investment Rating - Not mentioned Core View - From September to October, the supply of industrial silicon increases, and the supply - demand balance gradually becomes loose. The expected batch production reduction of silicon enterprises in Sichuan and Yunnan during the flat - dry season is at the end of October, and the supply surplus is more obvious in October and narrows in November. The cost increase during the flat - dry season in the southwest boosts market sentiment. In the short term, industrial silicon has insufficient upward driving force, and the price may turn to oscillation, with the main price fluctuation range between 8000 - 9500 yuan/ton. Attention should be paid to the production reduction rhythm of silicon material enterprises and industrial silicon enterprises in Sichuan and Yunnan in the fourth quarter [2]. Summary by Directory - **Spot Price and Main Contract Basis**: The prices of various types of industrial silicon increased on September 22 compared with September 19, and the basis also showed significant changes [2]. - **Inter - month Spread**: The spread between different months of industrial silicon futures contracts showed various changes [2]. - **Fundamental Data**: Monthly national and regional industrial silicon production increased, and the national and regional start - up rates also increased. The production of organic silicon DMC and polysilicon increased, while the production of recycled aluminum alloy decreased. Industrial silicon exports increased [2]. - **Inventory Change**: The factory - warehouse inventory in Xinjiang decreased, while that in Yunnan and Sichuan increased slightly. Social inventory and non - warehouse receipt inventory increased slightly, and contract inventory decreased slightly [2]. Group 3: Glass and Soda Ash Report Industry Investment Rating - Not mentioned Core View - **Soda Ash**: The soda ash futures market is weak. Although the manufacturer's inventory has decreased recently, the inventory has actually transferred to the middle and lower reaches, and the trade inventory continues to rise. The weekly production remains high, and there is still an over - supply situation compared with the current rigid demand. In the medium term, there is no significant increase in downstream capacity, so the demand for soda ash will continue the previous rigid - demand pattern. If there is no actual capacity exit or load reduction, the inventory will be further pressured. Attention can be paid to the implementation of policies and the load - regulation situation of alkali plants. It is advisable to short on rebounds [4]. - **Glass**: The glass futures market is weak. The spot market trading has become dull, and the inventory of some middle - stream areas remains high without obvious reduction. In the long - term, as the real - estate cycle is at the bottom, the industry needs capacity clearance to solve the over - supply problem. Attention can be paid to the implementation of regional policies and the inventory - replenishment performance of the middle and lower reaches during the "Golden September and Silver October" period. In the short term, sentiment - driven factors may drive the spot market to improve, and the sustainability needs to be tracked [4]. Summary by Directory - **Glass - related Price and Spread**: The prices of glass in different regions remained stable, and the prices of glass futures contracts decreased slightly [4]. - **Soda - Ash - related Price and Spread**: The prices of soda ash in different regions remained stable, and the prices of soda ash futures contracts decreased [4]. - **Supply**: The soda ash start - up rate and weekly production decreased, the float - glass daily melting volume decreased slightly, and the photovoltaic daily melting volume remained unchanged [4]. - **Inventory**: The glass factory - warehouse inventory and soda - ash factory - warehouse inventory decreased, while the soda - ash delivery - warehouse inventory increased. The glass factory's soda - ash inventory days remained unchanged [4]. - **Real - estate Data**: The new construction area, construction area, completion area, and sales area of real - estate all showed different degrees of change [4]. Group 4: Rubber Report Industry Investment Rating - Not mentioned Core View - On the supply side, the expected increase in future supply weakens the raw - material price and cost support, but the typhoon weather has raised concerns about short - term supply release. The pre - festival inventory replenishment of downstream tire factories is basically completed, and the inventory - reduction rhythm of natural rubber spot inventory has slowed down. On the demand side, although some enterprises still face shortages, the overall shipment performance is less than expected, and some enterprises' inventory may increase. Affected by the typhoon weather, the short - term rubber price will fluctuate strongly, with the 01 contract price ranging from 15000 - 16500 yuan/ton. Future attention should be paid to the raw - material output during the peak season in the main production areas and the impact of the La Nina phenomenon on supply. If the raw - material supply is smooth, the price may decline further; otherwise, it will continue to operate within the range [5]. Summary by Directory - **Spot Price and Basis**: The price of some rubber varieties remained stable, while the basis and non - standard price difference changed [5]. - **Inter - month Spread**: The spread between different months of rubber futures contracts showed various changes [5]. - **Fundamental Data**: The production of rubber in Thailand, Indonesia, and China in July showed different trends. The start - up rate of semi - steel and all - steel tires increased slightly. The domestic tire production in August increased, while the tire export decreased. The import of natural rubber and synthetic rubber increased [5]. - **Inventory Change**: The bonded - area inventory and the上期所 factory - warehouse futures inventory of natural rubber decreased, and the inbound and outbound rates of dry rubber in the bonded and general - trade warehouses in Qingdao changed [5]. Group 5: Logs Report Industry Investment Rating - Not mentioned Core View - The log futures market oscillated. The spot price of the main standard delivery products remained unchanged, and the inventory decreased significantly. The demand (outbound volume) decreased, while the supply (expected arrival of New Zealand logs) increased. As the "Golden September and Silver October" traditional peak season approaches, attention should be paid to whether the outbound volume improves significantly after entering the seasonal peak season. The current daily outbound volume is about 60,000 cubic meters, but it has not exceeded 70,000 cubic meters. The price below 800 yuan/cubic meter has high "receiving value". In the current pattern of "weak reality and strong expectation", it is recommended to go long on dips [7]. Summary by Directory - **Futures and Spot Price**: The log futures price oscillated, and the spot price of main standard delivery products remained unchanged [7]. - **Cost: Import Cost Calculation**: The RMB - US dollar exchange rate and import theoretical cost changed slightly [7]. - **Port Shipment and Departure Ship Number**: The port shipment volume and departure ship number from New Zealand to China, Japan, and South Korea decreased [7]. - **Main Port Inventory and Daily Outbound Volume**: The national coniferous log inventory decreased, and the daily outbound volume decreased [7].

Group 1 - The main contract for polysilicon futures experienced fluctuations, reaching a peak of 43,250.0 yuan, and closed at 42,945.0 yuan with a rise of 1.50% [1] - Various institutions have differing views on the future of polysilicon prices, with some expecting a potential correction while others maintain a bullish outlook [2] - The supply side of polysilicon shows an overall increase in production, but some companies are undergoing maintenance, leading to a mixed impact on capacity [2][3] Group 2 - The current macroeconomic environment shows a positive CPI and a weakening PPI, which may influence market expectations [2] - The demand side is under pressure due to reduced production schedules in downstream solar component manufacturing, despite recent price recoveries [2] - The operating rate for polysilicon in June was reported at 35.47%, with a year-on-year production decrease of 38% but a month-on-month increase of 3% [3]

1. Report Industry Investment Ratings No relevant information provided in the reports. 2. Core Views of the Reports Glass and Soda Ash - Yesterday, the soda ash futures market sentiment weakened, with the 09 contract dropping about 30 points. Although the overall market sentiment had improved earlier, the supply - demand pattern of soda ash remains in surplus, with continuous inventory accumulation. It is recommended to watch for opportunities to short on rebounds [1]. - The glass futures market sentiment declined yesterday, while the spot market remained strong. Currently, it is the off - season, and the industry needs capacity clearance. It is advisable to wait and see for now [1]. Logs - Yesterday, the log futures market fluctuated slightly stronger. The market is in a situation of weak supply and demand due to the off - season for demand and seasonal reduction in supply from New Zealand. The 09 contract is expected to fluctuate weakly, and attention should be paid to market sentiment and policy expectations [2]. Industrial Silicon - The spot price of industrial silicon increased by 150 - 200 yuan/ton, and the futures price rose by 90 yuan/ton. The supply is expected to increase. In the short - term, the price will fluctuate strongly, but attention should be paid to the risk of price decline due to the increase in warehouse receipts [3]. Polysilicon - The polysilicon spot price stabilized, and the futures price increased. There is still room for the futures price to catch up with the spot price. The market has a wait - and - see attitude, and there are both positive and negative factors. Attention should be paid to the risk of price decline [4]. Natural Rubber - The natural rubber price rebounded due to macro - sentiment, but the fundamental situation is still weak. It is recommended to short at the price range of 14,000 - 14,500 yuan/ton, and pay attention to raw material supply and US tariff changes [5]. 3.

1. Report Industry Investment Ratings No information about industry investment ratings is provided in the reports. 2. Core Views Natural Rubber - The fundamentals are expected to weaken. Hold short positions above 14,000 and monitor raw material supply in various producing areas and US tariff changes [1]. Polysilicon - Polysilicon is facing inventory accumulation pressure due to oversupply. Although prices are rising under policy expectations, downstream demand remains weak. It is beneficial for polysilicon - industrial silicon arbitrage and buying stocks of photovoltaic industry chain enterprises, but beware of the impact of high - cost transfer on weak demand [3]. Industrial Silicon - The spot price of industrial silicon is stable, and the futures price fluctuates. In the short term, the price is expected to fluctuate strongly supported by production cuts, but in the long term, over - supply pressure may increase. Pay attention to the impact of polysilicon production changes on demand and policy effects [4]. Glass and Soda Ash - Soda ash is in an obvious oversupply situation. Wait for the opportunity to short after the market sentiment fades. Glass has a short - term rebound, but the demand is weak. Wait for more cold - repair actions to bring a real turnaround and currently suggest waiting and seeing [6]. Logs - The log market is entering a period of weak supply and demand. The 09 contract is expected to fluctuate weakly [8]. 3.

1. Report Industry Investment Ratings No relevant content provided. 2. Core Views of the Reports Natural Rubber - In the context of expected supply increase and weak demand, the subsequent rubber price is expected to remain weak. Hold the short position at 14,000 and monitor the raw material supply in each production area and macro - event disturbances [2]. Industrial Silicon - In June, industrial silicon still faces a weak fundamental situation of oversupply, and the price remains under pressure. Recently, the rebound in coal prices brings an expectation of rising raw material prices, which supports the price, and the price may fluctuate at a low level [4]. Polysilicon - The fundamentals have not significantly improved, and the atmosphere at the Shanghai PV exhibition is bearish. However, due to the low price, hold short positions cautiously and pay attention to the pressure level around 35,000 yuan/ton. If the polysilicon production increases, it is beneficial for the arbitrage of buying industrial silicon and shorting polysilicon [5]. Glass and Soda Ash - For soda ash, the excess pattern is obvious, and there will be further profit - reduction. After the photovoltaic rush - installation, the growth of photovoltaic capacity has slowed down, and the overall demand has not increased significantly. After the maintenance, inventory accumulation may accelerate. - For glass, it still faces over - supply pressure in the future, and the industry needs capacity clearance. The 09 contract fluctuates around 1000 points, and a short - term bearish strategy can be considered [6]. 3.
