Report Industry Investment Ratings - No industry investment ratings were provided in the reports. Core Views Natural Rubber - The natural rubber market is expected to enter a seasonal inventory accumulation cycle, with short - term price range - bound. If raw material supply is smooth, there is further downward potential; if not, prices are expected to range between 15,000 - 15,500 [1]. Glass and Soda Ash - For soda ash, the long - term supply - demand pattern is bearish, and short - term rebounds should be treated as opportunities to go short. For glass, short - term long opportunities can be seized on dips, but the industry still needs capacity clearance to solve the over - supply problem [3]. Methanol - The methanol market is trading on the "weak reality" logic, with the core contradiction being high port inventories. Before Iranian gas restrictions, the weak reality will continue to be priced in [6]. Polyester Industry Chain - PX supply is stable, but November's supply - demand is expected to be loose. PTA is expected to be in a tight - balance in the short - term but loose in the medium - term. Ethylene glycol is under pressure due to expected high inventory accumulation. Short - fiber and bottle - chip markets also face supply - demand challenges [8]. Polyolefins - Polypropylene and polyethylene both show increasing supply and demand, but the market still faces pressure from new capacity and supply increases [11]. PVC and Caustic Soda - Caustic soda prices are expected to be weak in the short - term due to increased supply and weak demand. PVC is in an over - supply situation, and prices are expected to continue to be weak [13]. Pure Benzene and Styrene - Pure benzene supply is expected to be loose, and price drivers are weak. Styrene supply - demand may be in a tight - balance, but cost support is insufficient [14].

Report Industry Investment Ratings No relevant content provided. Core Views Polyolefins - The supply of PE is increasing steadily, with significant profit improvement, continuous increase in the operating rate, and limited planned maintenance. Overseas inventory clearance at the end of the year also brings impacts, highlighting long - term supply pressure. PP's valuation has been significantly repaired due to the sharp decline in propane and crude oil. Although there are more recent overhauls in PP, the new device commissioning pressure in October is large, and the demand side lacks bright performance. The supply - demand structure of polyolefins is loose, and the upside space of the 01 contract is limited. Overall, the macro - environment is pessimistic, and the prices of PP and PE face pressure [2]. Methanol - At the port, due to sanctions, some warehouses do not accept sanctioned vessels, increasing the willingness to hold spot goods. Coupled with supply - side disturbances, the port basis has strengthened significantly. Overseas production has declined, and some devices have stopped. In late October, attention should be paid to the expected supply reduction caused by overseas gas restrictions. Inland supply has a certain bottom - support for prices due to a relatively healthy inventory structure. The demand side is weak. Overall, the price may continue to fluctuate under the supply - demand game, and attention should be paid to the port de - stocking rhythm and the implementation effect of overseas gas - restriction expectations [4]. Benzene - Styrene - For pure benzene, although there are device overhauls, there are also new production capacity commissioning expectations, and the domestic supply is expected to remain at a relatively high level. The downstream demand support is limited, and the inventory in East China ports may continue to decline. The price drive is weak in October. For styrene, under the double pressure of inventory and industry profit, some devices are under overhaul, but new devices are about to be commissioned, and the overall supply will remain high. The demand side support is also limited, and the price drive is weak. In the short - term, the price is still under pressure [6]. Polyester Industry Chain - For PX, the supply has shrunk compared to expectations due to unexpected overhauls or load reductions of some devices, while the demand has increased. However, overall, the supply - demand is still weak, and the price is in a weak oscillation. For PTA, the spot basis continues to weaken, but the downward space is limited. The absolute price is also in a weak oscillation. For short - fiber, the price is supported in the short - term, but the cost - side support is weak. For bottle - chips, it is likely to enter a seasonal inventory accumulation period, and it follows the cost - side fluctuations. For ethylene glycol, the domestic supply is abundant, and it is expected to accumulate inventory in October, with the upper price limit under pressure [7]. PVC and Caustic Soda - For caustic soda, the demand support from the aluminum industry is weak in the short - term, but there may be long - term demand support. The supply is increasing in the short - term, and the price is weak. For PVC, the supply - demand pressure is large, the fundamental contradiction is difficult to resolve, and the price is weak. The cost - side provides bottom support, and short - term short positions can stop profit [8].
