Group 1: Report Industry Investment Ratings - Not provided in the content Group 2: Core Views of the Report - Various commodities in the energy - chemical sector show different trends. For example, PX is in a tight - balance supply - demand situation with positive spreads; PTA has a slightly upward - trending price with limited downside; MEG is weakly oscillating; rubber and paper pulp are oscillating; synthetic rubber has short - term support; asphalt is strengthened by geopolitical events; LLDPE is short - term weak and medium - term oscillating; PP has long - term pressure; etc. [2][10][11] Group 3: Summaries by Commodity PX, PTA, MEG - PX: 11 - 01 positive spread, 1 - 5 negative spread. Long PX and short EB. Buy on dips before mid - September. Supply will marginally increase in September, but PX supply - demand remains in a tight - balance due to upcoming PTA new production [5][10]. - PTA: Unilateral price is slightly upward - trending with limited downside. Partially stop profiting from long PTA and short MEG. Polyester sales are weak, but there is still demand for procurement and restocking [10]. - MEG: Unilateral price is weakly oscillating. Reduce short positions. Partially stop profiting from long PTA and short MEG. Hold 1 - 5 negative spread. Supply is expected to increase after October, while demand is weak [11]. Rubber - Rubber is oscillating. Most tire listed companies' revenues increased in H1 2025, but profits declined. In Q3, raw material prices rose, and tire companies' profits were squeezed. Domestic demand is weak, and inventory reduction is slow [12][16][17]. Synthetic Rubber - Synthetic rubber is short - term oscillating with support. The upper limit is pressured by high supply and inventory, and the lower limit is supported by anti - involution policies. It mainly fluctuates with macro - sentiment this week [18][20]. Asphalt - Asphalt is strengthened by geopolitical events. The US - Venezuela situation is tense. This week's domestic asphalt production decreased, and both factory and social inventories decreased [21][31][35]. LLDPE - LLDPE is short - term weak and medium - term oscillating. PE demand is improving due to the approaching peak season for the agricultural film industry. Recently, commodity sentiment has declined, and futures are weak. Supply remains stable in September, and inventory pressure is not significant [36][37]. PP - PP is short - term oscillating and long - term pressured. Short - term demand has improved, but the cost side is weak. Supply pressure will increase as maintenance devices resume production and new capacity comes online [40][41]. Caustic Soda - Caustic soda is widely oscillating. The main obstacle to price increase is export. Domestic demand is stable, and non - aluminum demand may improve in the peak season. The key lies in the production start - up rhythm in Guangxi [44][46]. Pulp - Pulp is oscillating. The pulp market showed a mild recovery yesterday. The supply - demand pattern has not changed significantly, and port inventory is high. Attention should be paid to port inventory reduction and downstream price increases [50][53]. Glass - Glass original sheet prices are stable. The short - term supply - demand situation has little change, and the mid - and downstream maintain a rigid procurement rhythm [55][56]. Methanol - Methanol is short - term rebounding and medium - term oscillating. The short - term is supported by the September 3rd parade event. The mid - term will return to the fundamental trading logic. Port inventory is high, but the price downside is limited [58][61][62]. Urea - Urea is short - term rebounding and medium - term pressured. It may be strengthened by macro - sentiment in the short term, but it is under pressure due to high inventory and high premium in the medium term [64][65][66]. Styrene - Styrene is medium - term bearish. After the end of anti - involution speculation, the long - short contradiction is accumulating. The industry still has high expectations for the peak season, but the medium - term fundamentals are weak [67][68]. Soda Ash - Soda ash spot market has little change. The domestic market is weakening, with a decline in comprehensive production and sluggish downstream demand [69][71]. LPG, Propylene - LPG: Macro risks are increasing, and crude oil costs are rising. The short - term trend is affected by factors such as CP paper prices and device maintenance [74][79]. - Propylene: Spot prices are supported, but there is a risk of decline. Attention should be paid to factors such as the spread with futures and device maintenance [74]. PVC - PVC is under pressure. The supply is expected to increase, demand is weak, and inventory is accumulating. The "alkali - chlorine compensation" model reduces the motivation for production reduction [82]. Fuel Oil, Low - Sulfur Fuel Oil - Fuel Oil: It turned down at night and may continue to be weaker than low - sulfur fuel oil in the short term [84]. - Low - Sulfur Fuel Oil: Fluctuations intensify, and the spread between high - and low - sulfur spot prices in the overseas market has risen significantly [84]. Container Shipping Index (European Line) - The container shipping index (European line) is widely oscillating. Freight rates show different trends, and the supply of shipping capacity also has corresponding changes [86].
