Report on the Rubber Industry 1. Investment Rating No investment rating provided in the report. 2. Core View The report anticipates that rubber prices will oscillate weakly in the short term, with the 01 contract trading in the range of 15,000 - 16,500. The supply side is affected by the rainy season and typhoons in the producing areas, and the expected increase in raw material output in the future suppresses the raw material prices. The cost support has weakened, and the pre - holiday inventory replenishment of downstream tire factories is basically completed, so the natural rubber inventory is unlikely to see a significant reduction. On the demand side, although some enterprises are short of goods, the overall sales performance is below expectations, and some enterprises may control production flexibly. As the holiday approaches, the risk - aversion sentiment of funds increases, and the macro - sentiment of commodities weakens [1]. 3. Summary by Directory Spot Price and Basis - The price of Yunnan state - owned standard rubber (SCRWF) in Shanghai decreased by 100 yuan to 14,700 yuan, a decline of 0.68%. The basis of whole - milk rubber decreased by 65 to - 835. - The price of Thai - standard mixed rubber decreased by 250 yuan to 14,750 yuan, a decline of 1.67%.

The 1 - 5 spread decreased by 10 to 5, a decline of 66.67%. The 5 - 9 spread increased by 25 to - 20, an increase of 55.56% [1]. Production and Consumption Data - In July, Thailand's production was 421,600 tons, an increase of 6,700 tons or 1.61% compared with the previous month. Indonesia's production was 197,500 tons, an increase of 21,300 tons or 12.09%. India's production was 45,000 tons, a decrease of 1,000 tons or 2.17%. China's production was 101,300 tons, a decrease of 1,300 tons [1]. - The weekly operating rate of semi - steel tires for automobiles was 73.66%, an increase of 0.20 percentage points.

Report on the Glass and Soda Ash Industry 1. Investment Rating No investment rating provided in the report. 2. Core View - **Soda Ash**: The fundamental problem of over - supply still exists. Although the manufacturers' inventory has decreased recently, the inventory has actually been transferred to the middle and lower reaches, and the trade inventory continues to rise. The weekly production remains high, and the over - supply still exists compared with the current rigid demand. In the medium term, there is no expectation of a significant increase in downstream production capacity, so the demand for soda ash will continue the previous rigid - demand pattern. If there is no actual production capacity withdrawal or load reduction, the inventory will be further pressured. It is recommended to short on rallies [3]. - **Glass**: The spot market has good transactions, and the inventory has decreased this week. However, the inventory of some middle - stream enterprises in some regions remains high. The deep - processing orders have improved seasonally but are still weak, and the operating rate of low - emissivity (Low - E) glass is continuously low. In the long - term, the real - estate cycle is at the bottom, and the completion volume is shrinking. The industry needs to clear production capacity to solve the over - supply problem. It is necessary to track the implementation of regional policies and the inventory - replenishment performance of the middle and lower reaches during the "Golden September and Silver October" [3]. 3. Summary by Directory Price and Spread - **Glass**: The price of glass 2505 increased by 15 yuan to 1343 yuan, an increase of 1.13%.

The year - on - year growth rate of sales area was - 6.55%, a decrease of 6.50 percentage points [3]. Report on the Log Industry 1. Investment Rating No investment rating provided in the report. 2. Core View As the "Golden September and Silver October" traditional peak season approaches, it is necessary to observe whether the shipment volume improves significantly. The current average daily shipment volume is still below 70,000 cubic meters. The price below 800 yuan per cubic meter has a high "receiving value". In the current pattern of "weak reality and strong expectation", it is recommended to go long on dips [4]. 3. Summary by Directory Futures and Spot Prices - The price of log 2511 increased by 3.5 yuan to 805 yuan per cubic meter, an increase of 0.44%. The price of log 2601 increased by 2 yuan to 818.5 yuan per cubic meter, an increase of 0.24%. The price of log 2603 increased by 1 yuan to 825 yuan per cubic meter, an increase of 0.12%. The price of log 2605 remained unchanged at 828 yuan per cubic meter [4]. - The 11 - 01 spread decreased by 15 to - 15. The 11 - 03 spread increased by 2.5 to - 20. The 11 - contract basis decreased by 3.5 to - 55. The 01 - contract basis decreased by 66.5 to - 68.5 [4].

Report on the Industrial Silicon Industry 1. Investment Rating No investment rating provided in the report. 2. Core View From a fundamental perspective, from September to October, as the supply of industrial silicon increases, the balance will gradually become looser. The expectation of large - scale production cuts in Sichuan and Yunnan silicon enterprises during the flat - and - low - water period is at the end of October, so the expected surplus in October is more obvious and will narrow again in November. At the same time, the increase in production costs in the southwest during the flat - and - low - water period raises the average industry cost, giving positive sentiment to the market. It is expected that the industrial silicon price will continue to lack upward driving force in the short term and may turn to oscillation, with the main price fluctuation range between 8,000 - 9,500 yuan per ton. It is necessary to pay attention to the production - cut rhythm of silicon - material enterprises and Sichuan and Yunnan industrial silicon enterprises in the fourth quarter [5]. 3.

Report on the Polysilicon Industry 1. Investment Rating No investment rating provided in the report. 2. Core View This week, the industry self - discipline meeting was held again to discuss the self - discipline process. Some leading enterprises have production - cut plans in the future. The increase in downstream prices, the meeting, and the low inventory of some enterprises (the inventory distribution among enterprises is uneven) provide support for the price increase of polysilicon enterprises. Currently, low - price resources in the polysilicon market are scarce and are being snapped up, while high - price resources still face some resistance from downstream. It is expected that the polysilicon market will continue to oscillate in the short term [6]. 3.
