1. Report Industry Investment Rating No relevant content provided. 2. Core View of the Report - The upward trend of the chlor - alkali industry is limited due to insufficient fundamental drivers [1]. - For PVC, the short - term market is dominated by macro - sentiment, and it may shift to fundamental logic later. The fundamentals have not improved significantly, with high upstream production and new production expectations in July - August, leading to large supply - side pressure. The demand is weak, and the cost side lacks support. There is pressure to compress chlor - alkali profits [4]. - For caustic soda, the macro - atmosphere related to the renovation of old facilities has weakened, and the market is oscillating weakly. The supply pressure is large, the demand has both rigid support and off - season weakness, and the inventory pressure is increasing [4]. 3.

1. Investment Ratings No investment ratings for the industries are provided in the reports. 2. Core Views Polyester Industry - PX: Short - term supply is stable, but 8 - month downstream PTA device maintenance increases and terminal demand lacks improvement. Its trend follows macro - sentiment and oil prices. PX09 is treated with caution and short - bias, and the PX - SC spread is expanded at low levels [2]. - PTA: Current load is around 80%, but 8 - month device maintenance increases. Supply - demand improves in the short - term but weakens in the medium - term. The absolute price follows the cost and market sentiment. TA is short - biased above 4900, TA9 - 1 is in a rolling reverse spread operation, and the PTA disk processing fee is expanded at low levels [2]. - Ethylene Glycol: Supply turns loose in August, and demand is weak in the traditional off - season. It is greatly affected by the macro in the short - term. EGO9 is on the sidelines, and 9 - 1 is in a reverse spread operation [2]. - Short - fiber: Supply - demand is weak in the short - term, and the absolute price follows the raw materials. The operation strategy is the same as TA, and the PF disk processing fee fluctuates between 800 - 1100 [2]. - Bottle - chip: Supply is high, demand follows up generally, and the processing fee increase is limited. The absolute price follows the cost. PR is the same as PTA, and the PR main disk processing fee is expected to fluctuate between 350 - 600 yuan/ton [2]. Urea Industry The core contradiction of the urea fundamentals is unresolved, and the market is in a shock pattern. It is recommended to use a band - trading idea, and the release of export demand needs to be tracked [10]. Crude Oil Industry Overnight oil prices rose, driven by macro and geopolitical factors. In the short - term, the upward momentum of prices depends on the continuation of geopolitical tensions. It is recommended to use a band - trading idea, with short - term long - bias [55]. PVC and Caustic Soda Industry - Caustic Soda: The disk is volatile and relatively resistant to decline. Spot prices are stable for now, and it is expected that the liquid caustic soda price will be stable this week. Attention should be paid to risk avoidance [43]. - PVC: The disk is volatile and relatively resistant to decline. Spot prices are rising, and export expectations are good. However, the overall supply exceeds demand, and short - term caution is recommended [43]. Pure Benzene and Styrene Industry - Pure Benzene: Supply - demand improves slightly in the first quarter, but the destocking amplitude is limited. It follows the overall market sentiment in the short - term, and the main contract BZ2603 follows the oil price and styrene [46]. - Styrene: Supply - demand is expected to be weak, and the basis is weakening. The price is under pressure, and EB09 is in a rolling short - bias operation [46]. LLDPE and PP Industry In August, the supply pressure of PP and PE increases, and there is potential restocking demand. The overall valuation is moderately high, and the fundamental contradiction is not significant. PP is short - biased (7200 - 7300), and LP01 is held [50]. Methanol Industry Inland maintenance will peak in early August, production is high, ports are slightly accumulating inventory, and the basis is weakening. In August, imports are still high, and downstream demand is weak. The MTO09 profit can be expanded at low levels [58]. 3.

1. Investment Ratings - No investment ratings for the industries are provided in the reports. 2. Core Views Polyester Industry - Short - term PX supply is stable, but downstream PTA device maintenance increases in August and terminal demand lacks improvement, so PX trends follow macro - sentiment and oil prices. Strategies include being cautiously bearish on PX09 around 7000 and expanding the PX - SC spread at low levels [2]. - PTA load is around 80%, and its supply - demand in August is better than expected but still weak in the future. It is recommended to be bearish on TA above 4900, conduct TA9 - 1 rolling reverse arbitrage, and expand the PTA disk processing fee at low levels [2]. - In August, ethylene glycol supply - demand is near balance, with supply turning loose and demand weak. Strategies are to wait and see on EG99 unilaterally and conduct 9 - 1 reverse arbitrage [2]. - Short - term short - fiber supply - demand is weak, and its price follows raw materials. The PF disk processing fee fluctuates between 800 - 1100 [2]. - Bottle - chip processing fee has recovered, but demand is average, and supply is high. The absolute price follows the cost end. PR is the same as PTA unilaterally, and the main - contract disk processing fee is expected to fluctuate between 350 - 600 yuan/ton [2]. Crude Oil Industry - Overnight oil prices rose due to geopolitical uncertainties. Short - term trading focuses on geopolitical risks, and the disk fluctuates along the upper margin of the range. It is recommended to use short - term band strategies, with resistance levels for WTI at [69, 70], Brent at [72, 73], and SC at [525, 535]. Options can capture opportunities from increased volatility [7]. Pure Benzene - Styrene Industry - In the third quarter, pure benzene supply - demand improves slightly, but new device production limits inventory reduction. Its price follows market sentiment. The main - contract BZ2603 follows oil prices and styrene unilaterally [10]. - Styrene supply - demand is expected to be weak, and port inventory increases. Its price is under pressure, and EBO9 should be operated with a rolling bearish strategy [10]. Methanol Industry - Inland methanol maintenance is expected to peak in early August, with high production, port inventory accumulation, and weak downstream demand. It is recommended to expand the MTO09 profit at low levels [30][31]. Polyolefin Industry - In August, PP maintenance decreases, and PE supply pressure increases. Demand is low in July, but there is potential for restocking. Strategies include being bearish on PP unilaterally (7200 - 7300) and holding LP01 [33]. Urea Industry - The urea disk rebounds slightly, but the core contradiction remains. Supply is high, and export policies restrict demand, leading to inventory accumulation. Attention should be paid to the start of autumn fertilizers and the resumption of previously - shut - down devices [40]. Chlor - alkali Industry - The caustic soda disk is strong, and the spot price is stable. Supply increases, and inventory may rise. It is recommended to be cautious due to macro - disturbances [46]. - The PVC disk sentiment recovers slightly. Supply is expected to increase, and domestic demand is weak, but export expectations are good. It is recommended to be cautious in the short term [46]. 3. Summaries by Catalog Polyester Industry - **Prices and Cash Flows**: On July 29, most polyester product prices and cash flows changed slightly. For example, POY150/48 price was 6720 yuan/ton, up 0.1% from the previous day [2]. - **开工率**: Asian PX, Chinese PX, and PTA开工率 decreased slightly, while MEG综合开工率 and coal - made MEG开工率 increased [2].
