Group 1: Natural Rubber Industry Report Industry Investment Rating Not provided Core Viewpoints The fundamentals of natural rubber have changed little. The upstream cost side still provides support, while downstream players are resistant to high - priced raw materials. The reference range for the 01 contract is 15,000 - 16,500. Follow - up attention should be paid to the raw material output in the peak production season of the main producing areas and the possible impact of the La Nina phenomenon on supply. If the raw material supply is smooth, consider short - selling; if not, the rubber price is expected to remain high [1]. Summary by Relevant Catalogs - **Spot Prices and Basis**: On September 15, the price of Yunnan state - owned standard rubber (SCRWF) was 15,000 yuan/ton, up 0.33% from September 12. The full - latex basis decreased by 14.37%. The price of Thai standard mixed rubber increased by 1.34%. The price of cup rubber in the international market decreased by 0.67%, while the price of glue increased by 0.36%. Some domestic raw material prices remained unchanged [1]. - **Inter - month Spreads**: The 9 - 1 spread decreased by 4.46%, the 1 - 5 spread increased by 75.00%, and the 5 - 9 spread increased by 2.91% [1]. - **Fundamental Data**: In July, Thailand's production increased by 1.61%, Indonesia's by 12.09%, India's decreased by 2.17%, and China's decreased by 1.27%.

Group 2: Glass and Soda Ash Industry Report Industry Investment Rating Not provided Core Viewpoints - **Soda Ash**: The overall sentiment of the commodity market has improved, and soda ash has rebounded due to macro - sentiment. However, the fundamental oversupply problem still exists. In the medium - term, downstream demand will remain at the previous rigid - demand level. After the traditional summer maintenance season, with high supply, if there is no actual production capacity exit or load reduction, inventory will face further pressure. It is advisable to short on rebounds [3]. - **Glass**: The glass market has rebounded due to the improvement of the macro - atmosphere. Last week, the spot market had good transactions and inventory decreased. However, the inventory in the middle reaches has not been significantly reduced. In the long - term, the real - estate cycle is at the bottom, and the industry needs to clear excess capacity. Short - term: stay on the sidelines; medium - term: pay attention to the actual demand in the peak season [3]. Summary by Relevant Catalogs - **Glass - related Prices and Spreads**: The prices of glass in North China, East China, Central China, and South China remained unchanged.

The glass factory's soda ash inventory days remained unchanged [3]. - **Real - estate Data**: The year - on - year growth rate of new construction area increased by 0.09%, the construction area decreased by 2.43%, the completion area decreased by 0.03%, and the sales area decreased by 6.50% [3]. Group 3: Log Industry Report Industry Investment Rating Not provided Core Viewpoints The log market shows a pattern of "weak supply and demand, stable prices, and slightly decreasing inventory". The core contradiction lies in the game between weak demand and fluctuating supply. Prices are temporarily stable with cost support. Follow - up attention should be paid to the improvement of shipment volume in the seasonal peak season. Currently, the 09 contract has new registered warehouse receipts, and the spot market pressure has increased. It is recommended to go long on dips [4]. Summary by Relevant Catalogs - **Futures and Spot Prices**: On September 15, the log 2509 contract decreased by 0.39%, the log 2511 contract increased by 0.81%, and the log 2601 contract decreased by 1.15%.

Group 4: Industrial Silicon Industry Report Industry Investment Rating Not provided Core Viewpoints The cost of industrial silicon is expected to rise as raw material prices increase and the electricity price in the southwest region will go up during the dry season. Although the current output of industrial silicon has increased month - on - month, there are also news of capacity clearance. Considering the possible impact of the polysilicon enterprise self - discipline meeting next week and the increasing demand for downstream replenishment before the National Day, the price of industrial silicon may rise slightly. It is recommended to go long on dips, but also be aware of the inventory and warehouse - receipt pressure. The main price fluctuation range is expected to be 8,000 - 9,500 yuan/ton [5].

1. Report Industry Investment Rating No relevant content provided. 2. Report's Core View - The current oil price has been relatively undervalued, and its static fundamentals and dynamic forecasts remain favorable. It is a good opportunity for left - side layout. If the geopolitical premium re - emerges, the oil price will have more upside potential [3]. - For methanol, the valuation is still high, downstream demand is weak, and the price is under pressure. It is recommended to wait and see or short it within the sector when the price is high [5]. - For urea, although the current domestic demand is weak, the overall valuation is low, and the room for further decline is limited. It is advisable to go long at low prices and wait for potential positive factors [7]. - For rubber, a neutral approach is recommended for the short - term high - rising rubber price, with quick in - and - out operations. One can also consider a band - trading strategy of going long on RU2601 and shorting on RU2509 [11]. - For PVC, the supply is strong, demand is weak, and the valuation is high. The fundamentals are poor, and it is necessary to observe whether exports can reverse the domestic inventory build - up situation. The price may decline significantly after the anti - involution sentiment fades [11]. - For styrene, the BZN spread is expected to repair in the short term. After the high - level port inventory is reduced, the styrene price may oscillate upwards following the cost side [13][14]. - For polyethylene, the short - term price will be determined by the game between the cost side and the supply side. It is recommended to hold short positions [16]. - For polypropylene, the cost side will likely dominate the market, and the price is expected to follow the oil price and oscillate upwards [17]. - For PX, the load remains high, and it is expected to continue de - stocking. The valuation has support at the bottom but limited upside in the short term. One can consider going long following the oil price when the peak season arrives [19][20]. - For PTA, the supply is expected to continue building up inventory, and the processing fee has limited room for operation. One can consider going long following PX when the downstream performance improves in the peak season [21]. - For ethylene glycol, the fundamentals will turn from strong to weak, and the short - term valuation may decline [22]. 3.
