Report Industry Investment Ratings - Propylene, plastic: ☆☆☆ [1] - Pure benzene, styrene: ☆☆☆ [1] - PX, PTA: ☆☆☆ [1] - Ethylene glycol, short - fiber: ☆☆☆ [1] - Bottle chips, methanol: ☆☆☆ [1] - Urea, PVC: ☆☆☆ [1] - Caustic soda, soda ash: ☆☆☆ [1] - Glass: ☆☆☆ [1] Core Views - The overall chemical market shows a complex situation with different products having different supply - demand relationships, price trends, and influencing factors. Some products are facing supply pressure and weak demand, while others have certain support from demand but also face future uncertainties [2][3][5] Summary by Category Olefins - Polyolefins - Olefin futures' main contracts fluctuated narrowly. Supply is controllable as restarting devices are not in place, and downstream demand provides some price support [2] - Polyolefin futures' main contracts also fluctuated narrowly. Polyethylene maintenance decreased with increased domestic production, and downstream has pre - holiday stocking demand but faces post - holiday de - stocking pressure. Polypropylene prices are under pressure due to multiple factors such as demand differentiation, supply pressure, and high inventory [2] Pure Benzene - Styrene - Pure benzene oscillated downward. Although the current fundamental situation is okay with port inventory decreasing and spot price being relatively firm, high import volume and expected demand decline drag the market [3] - Styrene futures' main contracts fluctuated narrowly. Cost - end oil price provides support, but high inventory suppresses the price [3] Polyester - PX's strong expectation weakened, and PTA's profitability is still poor. Although the pre - holiday stocking in the polyester yarn industry has reduced inventory pressure, post - holiday demand is expected to weaken, and the supply - demand situation remains under pressure [5] - Ethylene glycol's domestic operation decreased slightly, and port inventory is low. However, new device trials and weakening demand may lead to a weak supply - demand situation in the fourth quarter [5] - Short - fiber's new capacity is limited, and inventory decreased. The pre - holiday stocking has fulfilled the positive expectation. Bottle chips showed a short - term strong trend due to typhoon - affected device shutdown, but long - term over - capacity is a pressure [5] Coal Chemical Industry - Methanol's main contract oscillated. Port inventory is expected to increase after the holiday, and the market is expected to be weak [6] - Urea prices increased slightly, but downstream follow - up is cautious. The domestic supply - demand situation is loose, and attention should be paid to policy adjustments [6] Chlor - Alkali - PVC oscillated weakly with high supply and high inventory. Domestic downstream pre - holiday stocking intention is low, and foreign demand is weak [7] - Caustic soda's futures price oscillated under the weak situation. Although there is an expectation of downstream stocking before alumina production, the current supply is high [7] Soda Ash - Glass - Soda ash weakened. The industry is de - stocking, and the downstream pre - holiday stocking is nearly over. The long - term supply is in excess [8] - Glass prices fell from a high level. Some manufacturers plan to increase prices, and attention should be paid to downstream restocking sentiment [8]
