1. Report Industry Investment Rating No relevant content provided in the reports. 2. Core Views of the Reports Polyester Industry Chain - PX: The supply increment is obvious due to short - process losses and postponed maintenance of some domestic PX plants. The supply - demand outlook in the fourth quarter is weak, and PXN is expected to compress. Suggest to treat PX11's rebound with a short - bias and focus on the support around 6500 [2]. - PTA: Supply is expected to shrink due to low processing fees and postponed new plant commissioning. However, demand growth is limited, and the basis is weakly volatile. Suggest to treat TA's rebound with a short - bias and focus on the support around 4500; conduct a rolling reverse spread on TA1 - 5 [2]. - Ethylene Glycol (MEG): Supply - demand is gradually weakening. It will enter the inventory accumulation phase in the fourth quarter. Suggest to sell call options EG2601 - C - 4400 at high prices and conduct a reverse spread on EG1 - 5 [2]. - Short - fiber: The short - term supply - demand pattern is weak. It has support at low levels but weak rebound drivers. The strategy is the same as PTA, and the processing fee on the disk fluctuates between 800 - 1000 [2]. - Bottle chips: The supply - demand is loose. PR follows the cost side. Suggest that the strategy for PR is the same as PTA, and the processing fee on the main disk is expected to fluctuate between 350 - 500 yuan/ton [2]. Chlor - alkali Industry - Caustic Soda: The market in Shandong may see price cuts in the short - term. It can be shorted in the short - term [29]. - PVC: The market is weakly volatile.

Report Industry Investment Ratings No information provided in the reports regarding industry investment ratings. Core Views Chlor - Alkali Industry - Last week, the caustic soda futures stopped falling and rebounded on Friday. Next week, the supply is expected to increase, and the operating rate of sample manufacturers will rise. The alumina price has been falling, squeezing the profit of domestic alumina enterprises and weakening the support for the spot price. In Shandong, due to the approaching National Day holiday, there may be a price cut in the short - term. [2] - Last week, PVC futures rebounded with the support of a warming macro - environment, but the supply - demand contradiction is still difficult to resolve. Next week, the output is expected to increase as many enterprises finish maintenance. The downstream product operating rate has limited improvement, and the procurement enthusiasm is average. It is expected that PVC will stop falling and stabilize from September to October. [2] Urea Industry - The urea futures are in a weak downward trend. The supply is increasing rapidly, and it is expected to reach 210,000 tons in October. The demand is weak, with a short window for autumn fertilizer procurement, high finished - product inventory of compound fertilizers, and slow follow - up of export orders. Without variables such as increased exports or early shutdown of gas - based plants, the spot price may continue to decline, and the futures will continue to fall significantly only if the spot price breaks below 1,550 yuan/ton. [8] Pure Benzene - Styrene Industry - The weekly supply - demand of pure benzene is weak. In September, the supply may remain high as some plants restart or postpone maintenance. The demand is weak as most downstream products are in the red, some secondary - downstream inventories are high, and styrene plants plan to reduce production in September - October. The price driving force is weak. [10] - The situation of styrene is similar to that of pure benzene. The supply - demand is expected to be loose in September, and the price driving force is weak. [10] Polyester Industry Chain - For PX, the supply has increased significantly due to delayed maintenance of some domestic plants, while the demand is weak as PTA processing fees are low, new PTA plants postpone commissioning, and many PTA plants plan to have maintenance. The PXN may be compressed in the fourth quarter, and the price driving force is weak. [14] - For PTA, the supply is expected to shrink, but the demand increase is limited, and the basis is not strongly supported. In the medium - term, the supply - demand is expected to be weak, and the price follows the raw material. [14] - For ethylene glycol, the short - term supply - demand is turning weak. Although the inventory is expected to decrease in September, the terminal market is weak. In the long - term, the supply - demand is expected to be weak in the fourth quarter due to new plant commissioning and seasonal demand decline. [14] - For short - fiber, the short - term supply - demand pattern is weak. The supply is high, and the demand is limited during the peak season. The price is supported at the low level but lacks upward driving force. [14] - For bottle - grade polyester chips, the supply - demand is still loose. Although the price and processing fees are supported by pre - holiday replenishment, the processing fee has limited upward space. [14][15] Polyolefin Industry - PP production has decreased recently due to losses in PDH and external - propylene procurement routes, leading to more unplanned maintenance and inventory decline. PE maintenance has reached a peak, and the operating rate is rising. The inventory of the upstream and mid - stream has decreased this week, and there are more import offers from North America. The 01 contract has a large inventory accumulation pressure, limiting the upward space. [20] Methanol Industry - The methanol market is trading high - inventory and fast loading in Iran. The coastal inventory has reached a record high, the market sentiment has worsened, and the price and basis have weakened slightly. The domestic supply is at a high level year - on - year, and although there is some unplanned maintenance recently, some plants are expected to resume production in mid - September, and the inventory pattern in the inland is relatively healthy. The demand is weak due to the traditional off - season. The port is still receiving a large amount of goods, with significant inventory accumulation and weak trading. The overall valuation is neutral. The futures are oscillating between high - inventory reality, weak basis, and overseas gas - restriction expectations in the future. [45] Crude Oil Industry - Last week, oil prices were weakly oscillating. The geopolitical premium has declined, and the market has refocused on the weak supply - demand fundamentals. The meeting between Chinese and US leaders has eased concerns about secondary sanctions on China for purchasing Russian oil, reducing the geopolitical risk support for oil prices. The expectation of future supply surplus, combined with the refinery maintenance season and the unexpected increase in US distillate inventory, has put pressure on oil prices. In the short - term, oil prices are under pressure.
