Report Industry Investment Ratings No information provided regarding industry investment ratings in the given reports. Core Views Methanol - Market is currently following a "weak reality" trading logic, with the core contradiction centered on high port inventories. The 01 contract faces challenges in inventory digestion, and the weak reality pattern may continue until the implementation of gas restrictions in Iran. The 05 contract is expected to see significant inventory reduction, and opportunities for MTO profit contraction in the 05 contract can be focused on later [3]. Polyester - PX supply is generally stable, but demand may be affected by potential PTA production cuts. The price rebound space is limited, and strategies include reducing long positions on rallies and short - selling above 6800, as well as attempting to narrow the PX - SC spread. - PTA is expected to have a slightly loose supply - demand situation with a small inventory build - up. The price rebound space is limited, and strategies include reducing long positions and short - selling on rallies, and treating TA1 - 5 as a rolling reverse spread. - Ethylene glycol is expected to face high inventory build - up in November - December, with significant upward pressure. Strategies include selling out - of - the - money call options on rallies and reverse - spreading EG1 - 5 on rallies. - Short - fiber supply is relatively high in the short term, but demand may weaken seasonally. The price rebound space is limited, and strategies are similar to PTA, with the focus on narrowing the processing margin on rallies. - Bottle - chip supply and demand remain in a loose pattern, and it is likely to enter a seasonal inventory build - up period. Strategies are similar to PTA, and the main contract processing margin is expected to fluctuate between 300 - 450 yuan/ton [6]. Polyolefins - PP supply increase is slowing down due to more unplanned maintenance, while PE supply is expected to increase as maintenance peaks. Demand has improved, but there is still significant pressure with increasing supply and decreasing demand. The 01 contract has inventory pressure, while the 05 contract may have long - term low - buying opportunities, and the monthly spread is suitable for reverse - spreading [8]. PVC and Caustic Soda - Caustic soda supply is expected to increase in November, with weak demand support. The price is expected to be weak and stable, and the overall trend is bearish. - PVC supply - demand remains in an oversupply situation, with continuous supply pressure from new capacity and weak demand in the traditional off - season. The price is expected to continue to oscillate weakly at the bottom, and the trading strategy is to short on rebounds [11]. Pure Benzene and Styrene - Pure benzene supply is expected to be loose in November, with limited demand support and increasing port inventories. The price driving force is weak, but attention should be paid to device changes due to low valuation. - Styrene supply may slightly decrease in November, with overall stable demand. The cost support is weakening, and the price driving force is limited. The strategy is to be bearish on EB12 price rebounds [12].

Report Industry Investment Ratings No relevant information provided. Core Views PVC and Caustic Soda - Caustic soda: Supply is at a high level, with weak demand support in the short - term due to shrinking industry profits in downstream alumina. However, there may be demand support in the medium - to long - term as the procurement cycle approaches and alumina has more planned production in Q1 next year [1]. - PVC: Supply returns to a high level as some maintenance enterprises resume production. Domestic downstream demand remains weak, and cost provides bottom - line support. The market is expected to be lackluster during the peak season [1]. Polyester Industry - PX: Supply is generally stable, and demand support has strengthened. It is in a situation of high short - term supply and demand but with a weak overall outlook. Cost support is limited, and the rebound space is restricted [2]. - PTA: Spot basis is weak, and the rebound is expected to face pressure due to factors such as the resumption of some device loads and the decline in oil prices [2]. - MEG: Port inventory decreases, but the upward driving force weakens. The far - month supply - demand structure is weak, and there is significant upward pressure [2]. - Short - fiber: Supply remains high, and demand has improved slightly, but the overall supply - demand drive is limited. The price rebound is expected to face pressure, but it has relatively stronger support at low inventory levels [2]. - Bottle - chips: Entering the seasonal inventory accumulation period, it mainly follows cost fluctuations, and the processing fee fluctuates [2]. Pure Benzene and Styrene - Pure benzene: Domestic supply is loose, and demand support is limited. The overall supply - demand expectation is still loose, and price drive is limited. It follows oil prices and styrene fluctuations [5]. - Styrene: Under inventory and profit pressure, supply pressure still exists, and demand support is limited. The supply - demand pattern remains weak, and the rebound is expected to face pressure [5]. Methanol - The port market is under pressure due to high inventory and weak demand. The inland market has price inversion problems. The MTO load decreases, and demand support is insufficient. The price is expected to decline in the short - term, and attention should be paid to port de - stocking and overseas gas - limiting expectations [8]. Polyolefins - PP: Supply recovery slows down due to more unplanned maintenance. PE: Supply is expected to increase as maintenance peaks. Demand has warmed up, and inventory is decreasing. The 01 contract has inventory pressure, while the 05 contract may have long - term low - buying opportunities [10].
