Report Industry Investment Ratings - Urea: ★★★ - Methanol: ★★★ - Pure Benzene: ★★★ - Styrene: ★★★ - Polypropylene: ★★★ - Plastic: ★★★ - PVC: ★★☆ - Caustic Soda: ★★★ - PX: ★★★ - PTA: ★★★ - Ethylene Glycol: ★★★ - Short Fiber: ★★★ - Soda Ash: ★☆☆ - Bottle Chip: ★★★ - Propylene: ★★★ - Glass: ★★★ [1] Core Viewpoints - The olefins and polyolefins market shows mixed trends with different factors influencing prices. The polyester market is affected by supply - demand dynamics and cost factors. The coal - chemical market has supply and demand changes due to seasonal factors. The chlor - alkali market is facing supply and demand imbalances. The soda - ash and glass market is in a weak situation with different outlooks for the future [2][4][5][6][7] Summary by Directory Olefins - Polyolefins - Olefins futures: The intraday trend of the main contracts of olefins futures is first down then up. Production enterprise inventory pressure is controllable, but downstream product cost pressure rises, limiting the upward space of propylene prices. There is still market rigid demand support [2] - Polyolefins futures: The main contracts of polyolefins futures fluctuate narrowly. The demand of the polyethylene downstream agricultural film industry continues to follow up, but overall orders may decline slightly. The supply pressure of polypropylene increases, and the weak fundamentals drag down the market [2] Pure Benzene - Benzene: The price of benzene continues to be weak. Domestic supply increases, demand is weak, and the port inventory accumulates slightly. There is an expectation of supply - demand improvement in the third quarter, but the real - time demand is weak [3] - Styrene: The main contract of styrene futures closes down in a volatile manner. Crude oil and pure benzene cannot provide effective support. Demand is weak and stable, supply is high, and port inventory accumulates significantly [3] Polyester - PX: The price of PX fluctuates with support at the lower integer level. The supply - demand expectation improves, but the real - time improvement is limited, and it is in a range - bound oscillation [4] - PTA: It runs below 4800 yuan/ton. Terminal weaving orders increase, but the real - time improvement is limited, and it is in a range - bound oscillation [4] - Ethylene Glycol: It falls back after hitting resistance at the 4500 yuan/ton level. The domestic load continues to increase, and it is expected to maintain range - bound oscillation [4] - Short Fiber: The supply and demand are stable. The price mainly fluctuates with the cost. If the demand improvement is realized in the medium - term, it can be considered for long - position allocation [4] - Bottle Chip: The industry has over - capacity, and the processing margin runs at a low level [4] Coal - Chemical - Methanol: The intraday methanol market is first weak then strong. The supply of inland methanol increases, traditional downstream average start - up declines, and inventory accumulates. But there is an expectation of a stronger market due to downstream device economic repair and pre - holiday stocking [5] - Urea: The futures and spot prices of urea continue to oscillate at a low level. Daily production decreases slightly but is still high year - on - year. The inventory of production enterprises increases, and port inventory also increases. Attention should be paid to the market sentiment around the Indian tender opening [5] Chlor - Alkali - PVC: It weakens. The cost support is not obvious, supply pressure is high, downstream procurement is not active, and social inventory accumulates. The futures price may oscillate weakly [6] - Caustic Soda: It performs strongly. There is still an overhaul expectation in East China, and the inventory pressure is small. The price is relatively firm but may face supply pressure in the future and is expected to be in a wide - range oscillation [6] Soda - Ash and Glass - Soda Ash: It continues to decline. The supply is expected to increase, and the inventory in the industrial chain is high. In the long - term, it is in a supply - demand surplus situation, and short - selling at high rebounds is recommended [7] - Glass: The weak situation continues, and the futures price drops sharply. The spot price decline narrows, and the glass factory destocks. The real - time situation is weak, but at a low - valuation level, long - position at the coal cost level can be considered [7]
