Report Investment Ratings - Urea: ★★★ [1] - Methanol: ★★★ [1] - Pure Benzene: ★★★ [1] - Styrene: ★★★ [1] - Propylene: ★★★ [1] - Plastics: ★★★ [1] - PVC: ★★★ [1] - Caustic Soda: ★★★ [1] - PX: ★★★ [1] - PTA: ★★★ [1] - Ethylene Glycol: ★★★ [1] - Short Fibre: ★★★ [1] - Glass: ★★★ [1] - Soda Ash: ★★★ [1] - Bottle Chips: ★★★ [1] Core Views - The olefin - polyolefin market shows mixed trends. Propylene prices are boosted by improved supply - demand, while polyolefin has different supply - demand situations for polyethylene and polypropylene [2]. - The pure benzene - styrene market has different outlooks for different periods. There is a seasonal improvement expectation in Q3 for pure benzene, and benzene - styrene has stable supply and limited downstream boost [3]. - The polyester market has various factors affecting different products. PX has positive valuation, ethylene glycol is multi - factor intertwined, short - fibre has positive demand expectations, and bottle chips face long - term over - capacity pressure [5]. - The coal - chemical market has different performances for methanol and urea. Methanol has weak reality but strong expectation, and urea is affected by market sentiment and export news [6]. - The chlor - alkali market shows different trends for PVC and caustic soda. PVC is expected to be weak, and caustic soda is strong in the short - term but limited in long - term increase [7]. - The soda ash - glass market is weak. Soda ash has an over - supply situation, and glass has cost support but weak demand [8]. Summary by Categories Olefin - Polyolefin - Propylene futures rose, with positive supply - demand factors such as downstream restocking and supply - side changes [2]. - Polyolefin futures had a mixed performance. Polyethylene has supply pressure and slow demand, while polypropylene has short - term supply support and slow demand recovery [2]. Pure Benzene - Styrene - Pure benzene has a seasonal improvement expectation in Q3 but may face pressure in Q4. It is recommended for monthly - spread band trading [3]. - Styrene has cost support, stable supply, and limited downstream boost, maintaining a consolidation pattern [3]. Polyester - PX has positive valuation due to improved demand expectations. PTA is affected by device news with limited impact [5]. - Ethylene glycol has a mixed situation with increased supply and stable demand, and needs to focus on policy and demand recovery [5]. - Short - fibre has positive demand expectations in the peak season and is recommended for long - term allocation. Bottle chips face long - term over - capacity pressure [5]. Coal - Chemical - Methanol has weak current conditions but strong expectations, with port inventory issues and changes in supply and demand [6]. - Urea is affected by market sentiment and export news, with a loose short - term supply - demand situation [6]. Chlor - Alkali - PVC is expected to be weak due to high supply, low demand, and increased export pressure [7]. - Caustic soda is strong in the short - term due to demand for restocking but has long - term supply pressure [7]. Soda Ash - Glass - Soda ash has an over - supply situation with high inventory at all levels, and its price is under pressure [8]. - Glass has cost support but weak demand, with a slowdown in inventory accumulation [8].
