1. Report Industry Investment Ratings No information regarding industry investment ratings is provided in the reports. 2. Core Views of the Reports Methanol Industry - The inland market will see a continuous increase in production. The marginal devices in the inland area are in a loss - making state. The market sentiment has improved due to some Iranian devices starting to shut down due to gas restrictions. The price and basis have both strengthened. It is expected to be volatile and slightly stronger in the short term [1]. Crude Oil Industry - Overnight oil prices rebounded due to the increasing expectation of the Fed's interest rate cut in December and the unsuccessful Russia - Ukraine negotiations. However, under the pressure of continuous production increase by OPEC+ and the record - high US crude oil production, the supply - demand pattern of crude oil remains weak. Brent crude oil is expected to fluctuate in the range of $60 - 66 per barrel in the short term [5]. Polyolefin Industry - For PP, there is a pattern of both supply and demand increasing. The supply has recovered due to fewer maintenance, and the inventory has decreased slightly. For PE, there is a situation of increasing supply and decreasing demand. Although the unplanned maintenance eases some supply pressure, the imported goods are abundant, and the demand is generally weak. The 01 contract is still under great pressure [8]. Glass and Soda Ash Industry - Soda ash has an overall surplus pattern. The weekly production has declined due to some devices reducing their loads, and the soda ash factories have reduced their inventory stage by stage. In the medium term, the demand for soda ash will continue the previous rigid - demand pattern. The supply - demand situation will be further pressured without actual capacity withdrawal or load reduction. Glass has a short - term positive performance driven by cold - repair benefits, but in the long term, it is still under pressure due to the weakening demand and the surplus pattern [9]. Styrene Industry - For pure benzene, the supply is generally loose, and the demand support is limited. The port inventory has increased significantly, and the supply - demand expectation is generally loose. The price may be adjusted due to the drag of oil prices in the short term. For styrene, the supply of goods is limited, and the demand support is expected to be limited. The rebound space is restricted [10]. Natural Rubber Industry - The supply cost is strongly supported, but the inventory is increasing seasonally, and the terminal demand support is insufficient. The downstream enterprise's operating rate is expected to decline further. The natural rubber market is expected to enter a range - bound consolidation [11]. PVC and Caustic Soda Industry - Caustic soda has certain supply - demand pressure, and the price is expected to be weak. PVC has a surplus supply - demand pattern, and the price is expected to continue the weak trend at the bottom [12]. Polyester Industry - PX has limited short - term drive but strong medium - term support. PTA's supply - demand expectation has been significantly repaired, but the rebound space is limited. Ethylene glycol is expected to fluctuate at a low level. Short - fiber's supply - demand is weak, and the processing fee is expected to be compressed. Bottle - chip's supply - demand is in a loose pattern, and the processing fee is expected to decline [13]. LPG Industry - The LPG price has declined, the inventory has increased, and the operating rates of upstream and downstream industries have changed. The overall market situation needs further attention [15]. 3.
