1. Report Industry Investment Ratings No information about industry investment ratings is provided in the reports. 2. Core Views Urea - The current core driver of the futures market is the strong expectation of the substantial relaxation of export policies. China may resume urea exports to India, opening an incremental market window. The policy requires concentrated exports by the end of September, overlapping with the domestic autumn storage period and creating demand resonance. The short - term market is likely to fluctuate strongly, and future attention should be paid to the impact of enterprise maintenance on daily production, changes in rigid and reserve demand, and export port collection [1]. Polyester Industry Chain - **PX**: Domestic PX supply is expected to increase, and the supply - demand situation in August is expected to weaken marginally. However, due to the traditional peak demand season and new PTA device commissioning expectations, the medium - term supply - demand pressure is not significant. It is expected that PX prices will be supported at low levels, but the upward space is limited. It is recommended to treat PX11 as a short - term range of 6600 - 6900 and expand the PX - SC spread at low levels [4]. - **PTA**: In August, due to low processing margins, PTA device maintenance plans increased, and short - term basis was supported. However, with the commissioning of new devices, the medium - term supply - demand is expected to be weak, and the upward space for the basis is limited. In the short term, there is still some support, and it is recommended to treat TA as a short - term range of 4600 - 4800 and conduct reverse arbitrage on TA1 - 5 at high levels [4]. - **MEG**: Domestic coal - based MEG supply has increased, and overseas supply is expected to change. In August, the supply - demand is near balance, and it is expected to fluctuate with commodities. It is recommended that EG01 fluctuate in the range of 4300 - 4500 in the short term [4]. - **Short - fiber**: Both supply and demand have increased slightly. With the approaching of the peak demand season, there is some support for prices, but the cost - side drive is limited. It is recommended that PF10 fluctuate in the range of 6300 - 6500 in the short term, and the processing margin on the futures market fluctuate in the range of 800 - 1100 [4]. - **Bottle - chip**: During the peak consumption season in August, with device production cuts, the processing margin has support at the bottom. The absolute price still follows the cost - side. It is recommended that PR is similar to PTA in terms of unilateral trading, and the main - contract processing margin on the futures market is expected to fluctuate in the range of 350 - 500 yuan/ton, and go long on the processing margin at low levels in the short term [4]. Methanol - The current methanol market has a relatively high port inventory year - on - year, mainly due to a large amount of imports in August, and imports in September are still expected to exceed 1.4 million tons. The demand side is differentiated, with the traditional sector remaining weak, while MTO profits have improved. Attention should be paid to the start - up progress of a port MTO device at the end of August to early September. The 09 contract has accumulated a large amount of inventory, while the 01 contract is supported by the seasonal peak season and Iranian gas - restriction expectations [7][8]. Chlor - alkali Industry - **Caustic Soda**: The overall sentiment in the industrial product futures market has weakened. The caustic soda market rebounded previously and then fell back. The spot market trading is okay, and the spot price is generally stable. The demand has been good recently, but there is an expectation of increased supply in the future, and the increase in the number of warehouse receipts in the main production areas also has a negative impact. It is recommended to try short - selling [14]. - **PVC**: The supply side has new production capacity being put into operation, the domestic trade is weak, and the inventory pressure is increasing. The demand is difficult to improve, and the downstream industry is still in the off - season. It is recommended to be bearish [14]. Polyolefin - Static analysis shows that the supply and demand of PP/PE both increase, inventory is being depleted, and the basis is weak, with high warehouse receipts suppressing the market. Dynamically, PP has more unplanned maintenance and new device delays, and PE has increased maintenance from mid - August to early September, with supply decreasing and demand recovering. In terms of valuation, oil - end profits are good, MTO profits are restored, and PDH profits decline slightly. It is recommended that the unilateral market fluctuate in the short term and continue to hold the LP01 contract [19]. Pure Benzene - Styrene - **Pure Benzene**: In the third quarter, the supply - demand situation of pure benzene is expected to improve, and port inventory is expected to decline in August, providing some support for prices. However, the overall supply is still sufficient, and its own driving force is limited. It is expected to be relatively strongly supported in the short term but will be under pressure in the medium term. BZ2603 should follow the fluctuations of oil prices and styrene [21][22]. - **Styrene**: The short - term supply of styrene remains high, but with profit compression, some devices may be shut down for maintenance. Downstream 3S loads have increased, and export expectations have increased due to overseas device maintenance. The supply - demand situation is expected to improve, and port inventory is expected to continue to decline. It is expected that styrene prices will be supported at low levels, but the rebound is limited. It is recommended that EB09 fluctuate in the range of 7100 - 7400 in the short term and be treated as a short - selling opportunity on rebounds [22]. Crude Oil - Overnight oil prices were weak, mainly due to the expected increase in Russian supply from the proposed Russia - Ukraine summit by Trump and market concerns about oversupply. However, the gasoline crack spread has rebounded, and refinery processing volume is at a seasonal high, providing some support for oil prices. It is expected that oil prices will continue to fluctuate weakly in the short term. It is recommended to be bearish, expand the spread between October - November/December contracts at low levels, and wait for opportunities to expand the spread in the options market after volatility increases [24][26]. 3.

1. Report Industry Investment Rating No relevant content provided. 2. Core Views of the Report - The current fundamental market of crude oil is healthy. With low inventories in Cushing, combined with hurricane expectations and Russia - related events, crude oil has upward momentum. However, the seasonal demand weakness in mid - August will limit its upside. A short - term target price of $70.4/barrel for WTI is given, suggesting short - term long positions on dips and stop - profit, and left - side ambush for Russian geopolitical expectations in September and the hurricane supply - disruption season when oil prices slump sharply [2]. - For methanol, coal prices are rising, increasing methanol costs, but coal - to - methanol profits are still at a high level year - on - year. Domestic and overseas production capacity is increasing, leading to high supply pressure. Traditional demand has low profits, and olefin demand is weak. It is recommended to wait and see as the current situation is weak but may improve in the peak season [4]. - Regarding urea, domestic production has started to increase, and although enterprise profits are low, they are expected to bottom out. Supply is relatively loose. Domestic agricultural demand is ending, and overall demand is average. The price range is narrowing, and it is advisable to focus on long - position opportunities on dips [6]. - For rubber, it is expected to oscillate in the short term. A neutral approach is recommended, and partial closing of the long RU2601 and short RU2509 position is suggested [10]. - For PVC, the overall situation is supply - strong and demand - weak with high valuations. The cost of calcium carbide has declined, and the fundamentals are poor. It is recommended to wait and see [10]. - In the case of styrene, the market macro - sentiment is good, and there is still cost support. The BZN spread has room for upward repair, and port inventories are decreasing. The price may follow the cost to oscillate upward [12][13]. - For polyethylene, the market is expecting favorable policies from the Chinese Ministry of Finance in the third quarter, and there is cost support. But inventory pressure and seasonal factors exist. It is recommended to hold short positions [15]. - For polypropylene, Shandong refinery profits have stopped falling and rebounded, and the cost may dominate the market. It is expected to follow crude oil to oscillate stronger [16]. - For PX, the load is high, and downstream PTA has many short - term maintenance. However, due to new PTA installations, PX is expected to continue inventory reduction. There is support for valuation, but the upside is limited in the short term. It is recommended to follow crude oil to go long on dips [18][19]. - For PTA, supply may continue to increase inventory, and the processing fee has limited room. Demand is slightly improving, and it is recommended to follow PX to go long on dips when the peak - season demand improves [20]. - For ethylene glycol, the supply load is decreasing, and downstream load is increasing. Port inventories are decreasing, but the industry is expected to enter an inventory - accumulation cycle. Valuation is relatively high, and there is downward pressure on short - term valuation [21]. 3.

Report Industry Investment Rating No relevant information provided. Core Viewpoints - Although the geopolitical premium has completely dissipated and the macro environment is bearish, current oil prices are relatively undervalued. The static fundamentals and dynamic forecasts remain favorable, presenting a good opportunity for left - hand side layout.

Industry Investment Rating - No information provided Core Viewpoints - PX has a weak unilateral trend, with the main contract shifting positions. The 1 - 5 month - spread is in a reverse arbitrage. Although weekend sales volume boosts the overall price of the industrial chain, it doesn't change the medium - term weak trend. PXN has short - term support starting from late August [7]. - PTA has a weak unilateral trend. Hold the mid - term position of long MEG and short PTA. Under low processing fees, pay attention to the support of unplanned production cuts on PTA processing fees, and conduct 1 - 5 reverse arbitrage. PTA supply decreases while demand increases, but high坯布 inventory and weak crude oil prices affect its performance [8]. - MEG has a weak and oscillating unilateral trend. Hold the mid - term position of long MEG and short PTA. Keep the 9 - 1 spread in the range of - 50 to 0 and pay attention to 1 - 5 reverse arbitrage. This week, both supply and demand of ethylene glycol increase, but the near - end driving force for the industrial chain is weak [9].

1. Investment Rating No investment rating for the industry is provided in the report. 2. Core Views - **Polyester Industry Chain**: PX supply is expected to increase in August due to new device production and restart of some PX maintenance devices. The supply - demand situation is expected to weaken, and PX is expected to fluctuate weakly in the short term. PTA supply - demand is expected to improve, but the medium - term outlook is weak. Ethylene glycol supply is turning loose, with a small inventory build - up expected. Short - fiber, bottle - chip, and other products also face different supply - demand situations and price trends [2]. - **Pure Benzene - Styrene Industry**: The supply - demand of pure benzene is expected to improve in the third quarter, but the overall supply is sufficient, and it is expected to fluctuate weakly in the short term. The supply - demand of styrene is expected to be weak, with high port inventory, and it is expected to fluctuate weakly [7]. - **Urea Industry**: The main driving force for the rebound of the urea market is the surge in overseas export demand and the expected increase in domestic industrial demand. The secondary driving force is the possible marginal tightening of supply due to local maintenance. The short - term market is still in the shock range, and attention should be paid to multiple factors such as port collection volume and overseas prices [12]. - **Methanol Industry**: The domestic methanol production is at a high level, the port inventory is slightly increasing, the basis is weakening, and the downstream demand is weak. It is recommended to buy at low prices for the 01 contract [17]. - **Chlor - Alkali Industry**: The caustic soda market is in the off - season, with an expected increase in supply, and the overall outlook is neutral to weak. The PVC market is under pressure, with increasing inventory and weak demand, and the price is expected to continue to decline [27]. - **Crude Oil Industry**: The overnight oil price declined due to OPEC+ production increase, which is expected to increase global supply and suppress oil prices in the medium - long term. If there is no greater geopolitical shock, the supply - demand logic will continue to dominate the oil price trend [56]. - **Polyolefin Industry**: In August, the inventory pressure of PP and PE increases, and the demand is at a low level. However, there are potential restocking conditions in the seasonal peak season, and the overall valuation is moderately high with few fundamental contradictions [53]. 3. Summary by Directory Polyester Industry Chain - **Price and Spread**: On August 5, most polyester product prices and spreads declined. For example, POY150/48 price dropped by 20 yuan/ton, and its cash flow decreased by 74.7% [2]. - **Supply - Demand Analysis**: PX supply is expected to increase, and the supply - demand is expected to weaken. PTA supply - demand is expected to improve in August, but the medium - term outlook is weak. Ethylene glycol supply is turning loose [2]. - **Strategy**: For PX, close short positions for PX09 and pay attention to the support around 6650. For PTA, close short positions for TA and conduct TA9 - 1 rolling reverse arbitrage [2].

Polyolefin Industry - **Price and Spread**: On August 5, the prices of polyolefin futures and spot products increased to varying degrees, and the spreads between different contracts also changed [53]. - **Supply - Demand Analysis**: In August, the inventory pressure of PP and PE increases, and the demand is at a low level, but there are potential restocking conditions in the seasonal peak season [53]. - **Strategy**: Close short positions at 7200 - 7300 for the previous single - side short positions, and continue to hold the LP01 position [53].

Group 1: Report Industry Investment Rating - No information provided Group 2: Report Core Views - For PTA, it maintains a state of inventory accumulation but the absolute inventory level is not high. With low spot processing fees persisting and considering the limited inventory pressure of filament and the continuous inventory reduction of bottle - grade chips, polyester operation is expected to stabilize and has upward potential. Opportunities to expand processing fees on dips can be considered [2]. - For MEG, short - term inventory accumulation pressure is low, and port inventory is expected to remain at a low level. The situation is good and the profit is not low. However, there is an inventory accumulation expectation in the far - term due to overseas plant restarts and further increase in coal - based operation load. It should be viewed with wide - range fluctuations, and attention should be paid to the restart progress of satellite plants [5]. - For polyester staple fiber, as the finished - product inventory of polyester yarn is reduced, downstream operation may increase. Although the supply of staple fiber itself may also increase, considering the low - level processing fees on the futures market, opportunities to expand processing fees on dips can be considered [5]. - For natural rubber and 20 - grade rubber, the national explicit inventory remains stable at a non - high level but shows no seasonal reduction. The price of Thai cup rubber rebounds due to rainfall affecting tapping. The strategy is to wait and see [5]. Group 3: Summary by Related Catalogs PTA - **Device Changes**: Yisheng New Materials increased the load of its 7.2 - million - ton plant, and Taihua restarted its 1.5 - million - ton plant [2]. - **Data Changes**: From July 29 to August 4, crude oil decreased by 0.9, TA basis decreased by 8, and PTA processing fee decreased by 9, etc. [2].
