1. Report Industry Investment Ratings No investment ratings are provided in the reports. 2. Core Views of the Reports Polyester Industry - PX: Short - term supply is stable, affected by macro - sentiment and terminal restocking, but downstream PTA maintenance and weak terminal demand limit its drive. Follow macro - sentiment and oil prices, be cautious and bearish on PX09, and expand PX - SC spread at low levels [2]. - PTA: Load is around 80%, 8 - month maintenance increases, and short - term drive is limited. Be bearish on TA above 4900, conduct TA9 - 1 rolling reverse arbitrage, and expand PTA processing margin at low levels [2]. - Ethylene Glycol: Supply turns loose in August, but affected by macro factors. EG99 is on the sidelines, and 9 - 1 reverse arbitrage is the main strategy [2]. - Short - fiber: Short - term supply - demand is weak, follow raw materials. Unilateral strategy is the same as TA, and PF processing margin fluctuates between 800 - 1100 [2]. - Bottle - chip: Supply is high, demand is average, and processing margin has limited upside. PR is the same as PTA, and pay attention to expanding the processing margin at the lower end of the 350 - 600 range [2]. Crude Oil Industry - Overnight oil prices rose due to geopolitical uncertainties and better - than - expected demand data. Short - term trading focuses on geopolitical risks, and the market fluctuates along the upper edge of the range. Use short - term band strategies, and capture volatility opportunities in options [7]. Pure Benzene - Styrene Industry - Pure Benzene: Third - quarter supply - demand improves slightly, but new device production limits de - stocking. Follow market sentiment, and BZ2603 follows oil prices and styrene [13]. - Styrene: Supply - demand is weak, port inventory increases, and basis weakens. EB09 is rolling bearish [13]. Methanol Industry - Supply is high, port inventory may increase in August, downstream demand is weak, and MTO profit is low. Expand MTO09 profit at low levels [29]. Polyolefin Industry - In August, supply pressure increases for PP and PE, demand has potential restocking conditions, and overall valuation is moderately high. PP is bearish unilaterally (7200 - 7300), and hold LP01 [32]. Urea Industry - The disk rebounds slightly, but the core contradiction remains. Supply is high, export policies limit demand, and inventory pressure increases. Pay attention to autumn fertilizer progress and device restart [34]. Chlor - Alkali Industry - Caustic Soda: The disk is strong, and the spot is stable. Supply increases and inventory may rise. The price is expected to be stable, and pay attention to risk avoidance [37][40]. - PVC: The disk sentiment recovers. Supply may increase, domestic demand is weak, and export expectations are good. The supply exceeds demand, and be cautious in the short - term [37][40] 3.

1. Report Industry Investment Ratings No industry investment ratings are provided in the reports. 2. Core Views Polyolefin Industry - The valuation shows that the marginal profit is gradually recovering, and the supply and demand of PP and PE are simultaneously contracting, with inventory accumulation. The demand side continues to be in a weak state. There is a risk of capacity withdrawal for devices with a production history of over 20 years. Strategy-wise, there is an opportunity for PP to fluctuate on the short - side, and PE can be bought within a certain range [2]. Crude Oil Industry - Overnight oil prices rose due to the repair of market demand expectations after the alleviation of macro - tense emotions. However, the OPEC+ production increase plan and Sino - US trade uncertainties pose upward resistance. It is recommended to adopt a short - term band strategy [5]. Pure Benzene and Styrene Industry - Pure benzene's previous maintenance devices are gradually restarting, and its downstream price transmission is not smooth. The short - term trend of pure benzene fluctuates with the overall market sentiment. Styrene's supply - demand expectation is weak, but it is supported in the short - term by the domestic anti - involution sentiment, with limited upside [44]. Methanol Industry - Inland methanol prices fluctuate slightly. The supply side has high maintenance losses in July but there is a restart expectation. The demand side is restricted by the traditional off - season. The port side is expected to accumulate inventory from July to August. In the short - term, the cost is lifted by coal, and the 09 contract's fluctuation range moves up. It is advisable to buy the 01 contract at low prices [47]. Chlor - alkali Industry - For caustic soda, the short - term macro - disturbance is intense, and it is recommended to close previous long positions and wait and see. For PVC, the short - term trading logic is mainly dominated by macro - emotions, and it is recommended to wait and see [52]. Polyester Industry Chain - PX is expected to fluctuate strongly in the short - term. PTA may fluctuate strongly in the short - term. Ethylene glycol is expected to run strongly in the short - term. Short - fiber has no obvious short - term driver. Bottle - chip supply - demand has an improvement expectation [71]. Urea Industry - The urea futures market is in a range - bound pattern. The supply is sufficient, and the demand is weak, resulting in a supply - exceeding - demand situation. The future price breakthrough depends on the substantial warming of the demand side [78]. 3.
