Report Investment Ratings - No investment ratings are provided in the reports. Core Views Polyolefin (LLDPE & PP) - Supply: PP supply recovery is slowing due to unplanned maintenance, while PE supply is expected to increase as maintenance peaks. Attention should be paid to the potential impact of expanded international sanctions on domestic refinery loads [2]. - Demand: The demand side is warming up, with downstream开工 rising, especially in the agricultural film sector. Both LLDPE and PP inventories are decreasing [2]. - Strategy: The 01 contract still faces inventory pressure, while the 05 contract has less new capacity. Long - term low - buying opportunities for the 05 contract can be considered, and the impact of sanctions on refinery loads should be continuously monitored [2]. Methanol - Market Situation: The port methanol market is under significant pressure due to high inventories and weak demand. The inland market has deeper price drops as some external procurement stops. Overseas, multiple plants have shut down, and many MTO plants have reduced their loads due to profit issues [5]. - Market Logic: The market is trading on the "weak reality vs. strong expectation" logic, with the core contradiction being the game between high port inventories and potential supply reduction (overseas plant shutdowns/geopolitical factors) [5]. - Strategy: In the short - term, prices may continue to fluctuate. Attention should be paid to the port destocking rhythm and the implementation of overseas gas restrictions [5]. Chlor - alkali (PVC & Caustic Soda) - Price and Spread: There are various price changes in PVC and caustic soda products, including futures and spot prices, as well as spreads between different contracts [8]. - Supply and Demand: Caustic soda industry开工 is stable, while PVC开工 has decreased slightly. Downstream开工 of both products has some positive changes, and PVC inventories are increasing [8]. Pure Benzene - Styrene - Price and Spread: Prices of upstream raw materials such as crude oil, naphtha, and pure benzene have declined, while some spreads have changed. Styrene prices have also decreased, and its cash flow has improved to some extent [9][10]. - Inventory and开工: Both pure benzene and styrene inventories in Jiangsu ports have decreased, and there are changes in the开工 rates of related industries [12][13]. Polyester Industry Chain - PX: Supply is expected to contract due to unplanned maintenance or load reduction of some PX plants. Demand is supported by new PTA plants and improved terminal orders. However, the short - term rebound space of PX is limited due to weak oil price support [14]. - PTA: The spot basis is weak due to increased supply from load recovery and new capacity. The futures market is relatively firm but limited by the lack of substantial policies and weak cost - side expectations [14]. - Ethylene Glycol (MEG): Upward momentum is weakened by factors such as port conditions, plant restarts, and weak cost. The supply structure in the far - month is still weak [14]. - Short - fiber: Supply remains high, and demand has improved, leading to inventory reduction. However, the rebound space is limited due to weak downstream chasing willingness and compressed processing fees [14]. - Polyester Bottle - chip: Demand is weak in the off - season, and it is likely to enter a seasonal inventory accumulation period. The processing fee is expected to decline [14].
