1. Investment Ratings No investment ratings for the industries are provided in the reports. 2. Core Views Methanol - The price may continue to fluctuate under the game of supply and demand. Focus on the stability of overseas device operation, the customs - clearance efficiency of sanctioned vessels, and actual arrival performance. Pay attention to the port destocking rhythm and the implementation effect of overseas gas - limiting expectations [1]. Polyolefins (LLDPE & PP) - The inventory pressure after the holiday is still significant. The supply pressure is prominent in the medium - and long - term, and the demand lacks highlights. The upside space of the 01 contract is limited [5]. Caustic Soda - There is demand support in the medium - and long - term, but it is weak in the short term. It was previously recommended to be bearish, and now the short positions can be temporarily closed as the market stabilizes [8]. PVC - The short - term disk may continue to be under pressure. Although the supply pressure has slightly eased and exports have recovered, the demand in the peak season is weak. Pay attention to cost support and downstream demand performance [8]. PX - The supply and demand are expected to be weak in the fourth quarter. It will mainly fluctuate at a low level in the short term. It is recommended to wait and see and look for short - selling opportunities on rebounds, and mainly conduct reverse spreads on the monthly spread [9]. PTA - The short - term drive is limited, and it will mainly fluctuate at a low level. It is recommended to wait and see TA, pay attention to the support around 4500, and conduct rolling reverse spreads on TA1 - 5 [9]. Ethylene Glycol - It is expected to accumulate inventory in October, and the supply - demand structure is weak in the far - month. It is recommended to short EG01 on rallies, hold the seller of the out - of - the - money call option EG2601 - C - 4350, and conduct reverse spreads on EG1 - 5 [9]. Short Fibers - The absolute price is still under pressure in the short term, but it is relatively strong compared to raw materials due to low inventory. It is recommended to have the same strategy as PTA for the unilateral position, and widen the processing margin at a low level [9]. Bottle Chips - It is likely to enter the seasonal inventory accumulation channel. PR follows the cost end, and the processing margin improves in the short term. It is recommended to have the same strategy as PTA for the unilateral position, and the main contract processing margin is expected to fluctuate between 350 - 500 yuan/ton [9]. Pure Benzene - The overall supply and demand in October are expected to be loose, and the price drive is weak. BZ2603 follows the fluctuations of styrene and oil prices [10]. Styrene - The supply - demand is expected to be loose, and the price is still under pressure in the short term. EB11 should be treated as a short - selling opportunity on rebounds [10]. 3.

Report Summary 1. Investment Ratings The report does not provide any industry investment ratings. 2. Core Views - **Chlor - Alkali Industry**: The caustic soda market has a high supply, and there is a possibility of price cuts. PVC is expected to stop falling and stabilize in the peak season from September to October, but the supply - demand contradiction is still difficult to ease [2]. - **Crude Oil Industry**: The current oil market shows a game between weak macro - expectations and tight spot fundamentals. It is likely to operate in a short - term range. It is recommended to focus on unilateral segment operations [24]. - **Methanol Industry**: The port inventory has decreased. The supply in the inland is at a relatively high level, and the demand is weak. The overall valuation is neutral, and the futures price fluctuates between high inventory and overseas gas - restriction expectations [29]. - **Urea Industry**: The urea futures market shows a weak and volatile pattern, mainly due to the deepening contradiction between high supply and weak demand. Although the cost provides some support, it is difficult to reverse the market downturn [37]. - **Polyolefin Industry**: PP production has decreased recently, and the inventory has declined. PE maintenance has reached a high point, and the upstream and mid - stream inventory has decreased. The pressure of inventory accumulation for 01 contracts is relatively large, which limits the upward space [43]. - **Polyester Industry**: PX supply increases, and the fourth - quarter supply - demand is expected to be weak. PTA supply is expected to shrink, and the short - term basis is supported. Ethylene glycol supply - demand is gradually weakening. Short - fiber support is strong in the short - term, and bottle - chip supply - demand is still loose [46]. - **Styrene Industry**: The supply of pure benzene is loose, and the demand support is limited.

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.

Report Industry Investment Rating - Not provided in the content Core Views - For pure benzene, domestic attention is on the commissioning progress of Yulong Cracking Unit 2. There will be concentrated new capacity additions from August to September. Domestic existing unit operations are still stable, while the rhythm of imports has slowed down. Downstream pick - up has reached its peak and declined but remains at a decent level, leading to a decline in port inventory. Downstream operations of pure benzene are recovering from the bottom, but overall operations are still low, and short - term maintenance of styrene has dragged down the rigid demand for pure benzene [3]. - For styrene, downstream pick - up during the peak season remains at a relatively high level, and port inventory is waiting to be further reduced. Currently, the absolute level of port inventory is still high. There will be short - term maintenance in the first and middle of September, leading to a decline in operations, and port inventory has started to decline. However, operations may recover in the second half of September. Among styrene's downstream products, the operations of ABS and PS have slightly declined, EPS operations are decent, and ABS has a large inventory pressure [3]. Summary by Directory 1.
