1. Report Industry Investment Rating No information about the industry investment rating is provided in the reports. 2. Core Views Natural Rubber - Short - term开工 will remain high, but geopolitical factors still exist. With the post - holiday orders of domestic agents being sent out, the domestic shortage of some enterprises will be alleviated. Due to the high overseas raw material prices providing cost support and the geopolitical factors causing price fluctuations, the rubber price is expected to fluctuate within the range of 16,500 - 17,500 [1]. Urea - On March 10, the urea futures followed the chemical sector, opening low and moving high, and the spot market price was adjusted upwards. The fundamentals of urea have not changed much, with high - level production. There is still pressure on the supply side. There is still some demand for green - turning fertilizer in the agricultural sector, and industrial demand is recovering. In the short term, the urea price is relatively strong, but after the green - turning fertilizer season ends in the second half of the month, there may be a market downturn. The main contract should focus on whether it can break through the 1,860 - 1,900 range [4]. PVC and Caustic Soda - **Caustic Soda**: On March 10, the caustic soda futures hit the daily limit down during the session and then rose at the end. The spot market is still optimistic, and the caustic soda price has been slightly increased. The supply - side load is slowly recovering, and there is still pressure on inventory accumulation. The demand from the alumina industry is stable, and non - aluminum downstream demand is improving. Due to the Middle East conflict, the international supply chain risk has increased, and the export expectation has strengthened. However, the overall supply - demand situation is still weak, and attention should be paid to the actual delivery volume and price fluctuations [5]. - **PVC**: On March 10, the PVC futures price dropped significantly, and the low - price transactions in the spot market were good. The supply - demand situation has changed slightly. The ethylene - based production enterprises may reduce their loads in the long term, while the calcium carbide - based production enterprises have slightly increased their loads and costs. Domestic demand is normal, and foreign trade exports are waiting for new quotes. The PVC price may be passively pushed up, but it is also affected by the uncertainty of the cost - end transmission [5]. Glass and Soda Ash - **Soda Ash**: On March 10, the soda ash futures fell, and the spot price was driven up but the trading was light. The weekly production increased slightly, and the production line load fluctuated. The demand was average, and downstream enterprises replenished their inventories moderately. It is expected to continue to fluctuate and decline, and short - selling can be attempted at the current price [6]. - **Glass**: On March 10, the glass futures price dropped. The spot price was raised. The supply - side daily melting volume remained low, and a new production line was ignited. The demand from downstream deep - processing and low - e products was average, and the futures price decline reduced the purchasing intention of futures - spot merchants. The inventory of production enterprises still faced pressure, and it is expected to continue to accumulate this week. The cost increase from energy prices needs further observation. It is expected to fluctuate and decline, with a reference range of 1,000 - 1,150. It is recommended to wait and see [6]. Polyolefins - The Middle East geopolitical situation is the core driver. The short - term logic is dominated by cost - push and supply reduction, and the fundamentals are secondary. The market is in a "strong expectation, weak reality" game stage. The price fluctuates sharply following geopolitical news, and the high price lacks actual transaction support. After Trump's statement, the crude oil price fluctuated extremely, causing the domestic futures and spot prices to drop significantly, and the market is in a state of high volatility, low trading volume, and fragility [7]. Methanol - The methanol futures dropped significantly, and the spot was purchased on demand. The basis was relatively strong, and the overall transaction was okay. The domestic production device load remained at a relatively high level, but due to shipping interruptions, the market strongly expected a significant reduction in subsequent imports. The demand side remained weak, and the olefin开工 rate of the main downstream continued to decline. The current port inventory is still at a relatively high level in history, but the market expects the port to enter the de - stocking cycle. The current price trend is mainly driven by the supply interruption expectation and risk sentiment, and the subsequent trend depends on the actual progress of the geopolitical conflict [8]. LPG No specific view on the trend of LPG is provided in the report, only price, inventory, and开工 rate data are presented [10]. Pure Benzene and Styrene - **Pure Benzene**: Due to the geopolitical influence, the crude oil transportation is blocked, and the Asian refinery开工 rate is expected to be affected. Some refineries at home and abroad have adjusted their loads, and combined with some device maintenance plans, the pure benzene supply is expected to decline. The downstream styrene industry has maintained its profit and load at a relatively high level, and the short - term demand support is strong. The pure benzene supply - demand expectation has improved, but it will fluctuate with the crude oil price. It is recommended to wait and see on a single - side basis and shrink the spread between EB04 and BZ04 when it is high [12]. - **Styrene**: The styrene industry has good profits, and the supply in March will remain at a high level. The demand side is expected to gradually recover after the holiday, and the supply - demand in March is expected to slightly de - stock. It will also fluctuate with the crude oil price. The same strategy as for pure benzene is recommended [12]. Polyester Industry Chain - **PX**: Due to the continuous blockade of the Strait of Hormuz, some PX factories in Asia have issued force majeure, and the PX supply is gradually affected. After the holiday, some PTA devices have restarted or increased their loads due to improved processing fees, and the PX supply - demand situation is gradually improving. It is expected to fluctuate with the crude oil price. It is recommended to wait and see for now and go long at a low price after the market stabilizes [13]. - **PTA**: The PTA load has increased after the holiday, and the March device maintenance plan is less than expected. Although the supply - demand expectation has improved, there is still an inventory accumulation expectation. It will follow the cost - end fluctuation. It is recommended to wait and see on a single - side basis and pay attention to the oil price trend [13]. - **Ethylene Glycol**: In March, the domestic supply of ethylene glycol has significantly decreased due to the shutdown or load reduction of multiple coal - based and oil - based ethylene glycol devices. The closure of the Strait of Hormuz has affected the transportation of overseas sources, and the arrival volume of foreign ships will be low from mid - March. The polyester load will seasonally recover in March, and the de - stocking amplitude may increase. However, due to Trump's statement, the short - term price may decline. It is recommended to wait and see [13]. - **Short - fiber**: The short - fiber supply - demand pattern is still weak. It will follow the raw material price fluctuation and is affected by the cautious downstream procurement. It is recommended to have the same single - side strategy as PTA, and the PF disk processing fee will fluctuate between 800 - 1,100 [13]. - **Bottle - chip**: The domestic bottle - chip supply will gradually increase in March. The absolute price will follow the cost - end fluctuation, and the processing fee will fluctuate. It is recommended to have the same single - side strategy as PTA, and the PR main - contract disk processing fee is expected to fluctuate between 400 - 550 yuan/ton [13]. Crude Oil - WTI 04 - month contract closed at $83.45 per barrel, down 11.94%, and Brent 05 - month contract closed at $87.80 per barrel, down 11.28%. The G7 energy ministers did not reach an agreement on releasing strategic oil reserves. Due to the drone attack, ADNOC has closed its refinery. The US strategic oil reserve remains stable. It will take at least 4 - 6 weeks for the Gulf region to fully resume export functions, and Iran has not clearly stated to stop the blockade. It is expected that the oil price will continue to fluctuate significantly [14]. 3.

Report Industry Investment Ratings No information provided regarding industry investment ratings in the given reports. Core Views Methanol - Market is currently following a "weak reality" trading logic, with the core contradiction centered on high port inventories. The 01 contract faces challenges in inventory digestion, and the weak reality pattern may continue until the implementation of gas restrictions in Iran. The 05 contract is expected to see significant inventory reduction, and opportunities for MTO profit contraction in the 05 contract can be focused on later [3]. Polyester - PX supply is generally stable, but demand may be affected by potential PTA production cuts. The price rebound space is limited, and strategies include reducing long positions on rallies and short - selling above 6800, as well as attempting to narrow the PX - SC spread. - PTA is expected to have a slightly loose supply - demand situation with a small inventory build - up. The price rebound space is limited, and strategies include reducing long positions and short - selling on rallies, and treating TA1 - 5 as a rolling reverse spread. - Ethylene glycol is expected to face high inventory build - up in November - December, with significant upward pressure. Strategies include selling out - of - the - money call options on rallies and reverse - spreading EG1 - 5 on rallies. - Short - fiber supply is relatively high in the short term, but demand may weaken seasonally. The price rebound space is limited, and strategies are similar to PTA, with the focus on narrowing the processing margin on rallies. - Bottle - chip supply and demand remain in a loose pattern, and it is likely to enter a seasonal inventory build - up period. Strategies are similar to PTA, and the main contract processing margin is expected to fluctuate between 300 - 450 yuan/ton [6]. Polyolefins - PP supply increase is slowing down due to more unplanned maintenance, while PE supply is expected to increase as maintenance peaks. Demand has improved, but there is still significant pressure with increasing supply and decreasing demand.

Report Industry Investment Ratings - No investment ratings provided in the reports Core Views Methanol - The methanol market is currently trading on the "weak reality" logic, with the core contradiction being high port inventories. The inventory issue for the 01 contract cannot be resolved, and the weak reality will continue to be priced in until the Iranian gas restriction [3]. Polyolefins (LLDPE & PP) - PP supply recovery has slowed due to unplanned maintenance, while PE supply is expected to increase as maintenance nears its peak. Demand has improved, but there is still pressure as supply is expected to increase while demand may decrease. The 01 contract faces inventory pressure, while the 05 contract may present long - term low - buying opportunities, and the month - spread is biased towards reverse arbitrage [8]. Chlor - alkali (Caustic Soda & PVC) - In November, the caustic soda market faces supply - demand pressure, with prices expected to be weak and stable. PVC's supply - demand imbalance remains unimproved, with prices likely to continue weak and volatile, and a strategy of short - selling on rebounds is recommended [9]. Pure Benzene - Styrene - Pure benzene supply is expected to be loose in November, with weak price drivers. Short - term trading of BZ2603 should focus on short - selling on rallies following oil prices. Styrene supply may slightly decrease, and demand is expected to change little. The supply - demand situation is currently loose, and prices are expected to have limited drivers. EB12 should be short - sold on rebounds [10]. Polyester Industry Chain - PX supply is stable, but its price rebound is limited. PTA supply - demand is slightly loose, and its price rebound is under pressure. Ethylene glycol is expected to accumulate inventory, and its price faces upward pressure. Short - fiber prices are gradually under pressure, and bottle - chip supply - demand remains loose [11].

1. Report Industry Investment Ratings No investment ratings are provided in the reports. 2. Core Views of the Reports Methanol Industry - The expected peak of inland maintenance is in early August, with current production at a high level year - on - year. There was a slight inventory build - up at ports this week, and the basis weakened. Imports in August are still high, downstream demand is weak due to low profits, and MTO profits have weakened again. The 09 contract has a strong expectation of inventory build - up. In the short term, the proportion of fundamental trading has decreased due to a strong macro - environment. The MTO09 profit is low and the driving force is towards expansion, so it is advisable to expand the spread on dips [1]. Polyolefin Industry - In August, PP maintenance will decrease, and the supply pressure of PE will increase. With new device commissions, the inventory build - up pressure in August will rise. In July, the downstream开工率 of PP/PE was at a low level, and social inventory has accumulated, but downstream raw material stocks have been digested to a low level, with potential restocking conditions. The overall valuation is moderately high, and the fundamental contradictions are not significant. The strategy is to be bearish on PP unilaterally (7200 - 7300) and continue to hold the LP01 position [4]. Crude Oil Industry - Overnight oil prices rose, mainly due to the market's re - pricing of geopolitical risks. Previously, the market was in a pessimistic mood due to the narrative of "weak demand + OPEC+ production increase". Trump's reduction of the cease - fire deadline for Russia and the threat of "100% secondary tariffs" have increased market concerns about geopolitical risks. Geopolitical risks mainly affect the marginal change in supply, and the market needs to re - evaluate the probability of a 3 - million - barrel - per - day supply interruption of Russian oil. In the macro aspect, the energy deal after the US - EU tariff negotiation has strengthened the implementation of sanctions against Russia and increased cross - regional trade costs. Although the demand side is suppressed by the global tariff shadow, the short - term market focus is on the impact of geopolitical risks on the supply side. It is recommended to adopt a short - term band trading strategy, with resistance levels of [67, 68] for WTI, [69, 70] for Brent, and [512, 515] for SC. Options can be used to capture opportunities from increased volatility [7]. Polyester Industry - **PX**: Short - term supply is stable, driven by domestic macro - sentiment, terminal restocking at low levels is obvious, and the inventory pressure of polyester factories has been alleviated. However, in August, PTA device maintenance will increase, and terminal demand has not improved significantly. The medium - term expectation of crude oil is still weak, and PX's own driving force is limited. It is expected that short - term PX trends will be dominated by macro - sentiment. The strategy is to be cautiously bearish on PX09 around 7000 and expand the PX - SC spread at low levels [11]. - **PTA**: Current PTA load is around 80%. In August, PTA device maintenance will increase under low processing fees. Terminal restocking at low levels due to domestic macro - sentiment has alleviated the inventory pressure of polyester factories, and PTA supply - demand has improved compared to expectations. However, the medium - term supply - demand expectation is still weak. It is expected that short - term PTA trends will be dominated by macro - sentiment. The strategy is to be bearish on TA above 4900, carry out a rolling reverse spread trade on TA9 - 1, and expand the PTA processing fee at low levels [11]. - **Ethylene Glycol**: In August, supply - demand is near balance. With the restart of multiple coal - based ethylene glycol devices from late July to early August and the planned restart of Zhejiang Petrochemical in early August, and the plan of some EO - EG co - production devices to switch from EO to EG due to weak downstream demand, domestic supply has become looser. Overseas, multiple Saudi ethylene glycol devices have restarted, and import expectations for August have been revised upwards. Terminal orders are weak in the traditional off - season. Overall, supply - demand has become looser, but it is greatly affected by the macro - environment in the short term. The strategy is to wait and see on EGO9 unilaterally and conduct a 9 - 1 reverse spread trade [11]. - **Short Fiber**: The supply - demand of short fiber has weakened marginally. Although prices rebounded last week due to domestic macro - sentiment, downstream purchasing power is weak, and the willingness to chase prices is low. The processing fee has been significantly compressed. The short - term supply - demand expectation is still weak, and the absolute price fluctuates with raw materials. The strategy is the same as for TA unilaterally, and the PF processing fee on the disk will fluctuate in the range of 800 - 1100, with limited upward and downward driving forces [11]. - **Bottle Chips**: Currently, it is the peak season for soft - drink consumption. Some bottle - chip devices are maintaining production cuts, and the processing fee has recovered compared to before the cuts. However, demand follow - up is average, the soft - drink开工率 is down year - on - year, and the supply of bottle chips is still at a historical high, so the inventory reduction is not as expected, limiting the upward space of the processing fee. The absolute price still follows the cost side. The strategy is the same as for PTA unilaterally, and the main - contract processing fee on the disk is expected to fluctuate in the range of 350 - 600 yuan/ton. Pay attention to the opportunity to expand the spread at the lower limit of the range [11]. Pure Benzene - Styrene Industry - **Pure Benzene**: There is an expectation of restarting previously shut - down devices, and the price transmission of downstream products other than styrene is not smooth. Coupled with a relatively high absolute level of port inventory, its own driving force is limited. Recently, the domestic commodity market has been greatly affected by anti - involution sentiment, and the fundamental logic has weakened. Short - term pure benzene trends will fluctuate with the overall market sentiment. The main - contract BZ2603 has limited self - driving force and will follow the trends of oil prices and styrene unilaterally [15]. - **Styrene**: In the short term, styrene开工率 is at a high level. Downstream EPS/PS factories are reducing production due to compressed industry profits and are cautious in raw material procurement. The supply - demand expectation of styrene is weak, and port inventory continues to increase. Recently, the styrene basis has weakened significantly. As the domestic commodity market sentiment cools down, the fundamental logic weakens. Short - term styrene trends will fluctuate with the overall market sentiment, but the rebound space is limited due to the weak supply - demand expectation. The strategy is to conduct a rolling bearish operation on EB09 [15]. Urea Industry - The urea disk has significantly declined, mainly due to the contradiction between shrinking demand and relatively loose supply. The summer top - dressing season is coming to an end, agricultural demand is gradually shrinking, compound fertilizer factories only purchase opportunistically due to inactive demand, and industrial rigid - demand procurement cannot offset the decline in agricultural demand, resulting in weak overall demand support. Although the urea enterprise开工率 is below 200,000 tons per day, the daily output is still 16,700 tons higher than the same period last year, with sufficient supply, further exacerbating the supply - demand imbalance. In addition, the sharp decline in the black - goods sector and the resonance of market sentiment have also put pressure on the urea disk. In the short term, the market is hard to improve. It is necessary to pay attention to the progress of autumn fertilizer start - up and the resumption of production of previously shut - down devices [41]. PVC - Caustic Soda Industry - **Caustic Soda**: The overall market sentiment has declined, and the caustic soda disk has fallen, but the decline is relatively small compared to other varieties, remaining relatively firm. The spot market is temporarily stable, with a certain willingness to support prices. Fundamentally, the supply in the East China region is relatively abundant, non - aluminum demand has not improved significantly, and the downstream off - season continues. It is expected that the caustic soda price will be stable this week. Many downstream enterprises resist high prices, and inventory has increased with the increase in supply. In the short term, macro - disturbances are intense, and trading risks have increased. The disk shows signs of rising and then falling. It is recommended to be cautious and avoid risks [48]. - **PVC**: The market sentiment declined significantly yesterday. The main PVC contract fell by 2.68%. Many industrial products that were strongly pulled up by policy sentiment in the previous period hit the daily limit today, and PVC was also affected by the overall market sentiment and fell significantly. However, some previously shut - down devices have resumed production, and it is expected that the supply will increase this week. On the demand side, the domestic downstream product开工率 remains low, with no signs of improvement. The delay in the announcement of India's anti - dumping tax has provided time for exports, and export expectations are good. Overall, the supply exceeds demand in terms of fundamentals. With the decline in market sentiment, it is advisable to consider shorting on rallies [48]. 3.
