Report Overview 1. Report Industry Investment Rating No investment rating information is provided in the reports. 2. Report Core Views - **Polyolefins**: PE's current maintenance has reached a peak, and the start - up is gradually recovering. The inventory of the upper and middle reaches has decreased this week. Future attention should be paid to the supply rhythm and import offers. The pre - holiday CP settlement price has decreased, and the profit of PDH units has recovered. Attention should be paid to the return of PP units. In terms of demand, there are no bright spots, and there is significant inventory pressure after the holiday. Coupled with new capacity investment, the pressure of inventory accumulation in 01 is large, which limits the upside space [2]. - **Methanol**: The current market's core trading logic revolves around "high inventory + high imports". The port arrival volume remains consistently high, the inventory accumulation is significant, and the trading atmosphere has weakened, resulting in a downward price trend. The domestic supply is at a high level year - on - year. Although the number of unplanned maintenance units has increased recently, some units are expected to resume production in early October. The inventory pattern in the inland area is relatively healthy, providing some support for prices. The demand is weak due to the traditional off - season of downstream industries. In terms of valuation, the overall is in a neutral state. The current futures market is in a game situation, and future focus should be on the emergence of the inventory inflection point [5]. - **Polyester Industry Chain** - **PX**: The domestic PX load remains at a high level. The PTA processing fee is continuously low, new PTA device production is delayed, and multiple PTA units have maintenance plans. The PX supply - demand is expected to be weak in the fourth quarter, and there is an expectation of PXN compression. In the short term, PX has weak self - driving force, and the oil price support is limited. It is expected to fluctuate at a low level [8]. - **PTA**: The PTA supply is expected to shrink. The short - term downstream start - up remains at a relatively high level, and the PTA basis has been repaired, but the rebound space is limited under the weak expectation. In the short term, PTA has limited self - driving force, and the oil price support is limited. It is expected to fluctuate at a low level [8]. - **Ethylene Glycol**: After the National Day holiday, the port inventory has increased significantly. The domestic supply remains at a high level, and the supply - demand is gradually weakening. Therefore, the price of ethylene glycol is under pressure [8]. - **Short Fibers**: The short - fiber supply - demand pattern is weak. The supply remains at a high level, and the inventory pressure after the holiday is not significant. It is expected that the short - term support for short fibers is stronger than that of raw materials, but the driving force is limited, and the price will mainly follow the raw materials [8]. - **Bottle Chips**: In October, there is no news of further production cuts for bottle chips. The demand in the fourth quarter is in the traditional off - season. The demand side has limited support for bottle chips. It is expected that bottle chips will enter the seasonal inventory accumulation period, and the price will mainly follow the cost side [8]. - **Pure Benzene - Styrene**: The supply of pure benzene is expected to remain at a high level, and the demand growth has great uncertainty, with limited support. The supply - demand of pure benzene is expected to be loose, and the price driving force is weak. The supply of styrene is expected to increase, and the demand side support may be limited. The supply - demand of styrene is expected to be loose, and the price is under pressure after the holiday [9]. - **PVC - Caustic Soda** - **Caustic Soda**: The short - term demand for caustic soda lacks support and tends to be weak, and it can be treated bearishly in the short term. However, there is demand support in the medium and long term, and attention should be paid to the downstream restocking rhythm [10]. - **PVC**: The supply - demand contradiction of PVC is difficult to resolve. The supply is in an over - supply pattern, and the demand in the peak season is not strong. The cost side provides bottom support. It is expected that the downside space of PVC is limited during the peak season, and attention should be paid to the downstream demand performance [10]. 3. Summary by Directory Polyolefins - **Price Changes**: From September 30th to October 9th, the closing prices of L2601, L2509, PP2601, and PP2509 decreased, with declines of - 1.06%, - 0.86%, - 1.56%, and - 1.06% respectively.
