Report Investment Rating - No investment rating provided in the report Core Viewpoints - The terminal downstream demand for polyolefins has entered the traditional off - season, with limited market demand, general restocking enthusiasm, mainly rigid - demand procurement, and a cold market trading atmosphere. The supply side continues to increase, and the supply - demand contradiction has not been significantly improved. Currently, the number of PE inventory maintenance devices has increased, alleviating the PE supply side. The previously shut - down PP devices have gradually restarted, and the upstream production inventory of polyolefins has been depleted. It is expected that the future supply will increase. The downstream demand is in the off - season, the agricultural film operating rate is at a low level, the packaging film operating rate fluctuates slightly, and the operating rates of industries such as plastic weaving and BOPP have increased slightly [2] - For the trading strategy, it is recommended to be cautiously bearish on plastics for single - side trading, and there is no strategy for inter - period trading [3] Summary by Directory 1.

1. Report Industry Investment Rating No relevant information provided. 2. Core Views Polyester Industry - PX: Short - term prices are supported due to planned outages, delayed PTA maintenance, and restart of previous maintenance devices. Suggest short - term focus around 6600, and consider PX9 - 10 positive spreads and PX - SC positive spreads [18]. - PTA: Weekly supply - demand weakens, downstream polyester losses increase, and terminal demand is in a wait - and - see state. Short - term is under pressure. Suggest short - term focus on support around 4600 and TA9 - 1 short - selling on rallies [18]. - Ethylene Glycol (MEG): Expected to de - stock from May to June, but the upside is limited by polyester factory production cuts. Suggest unilateral wait - and - see and EG9 - 1 positive spreads on dips [18]. - Short - fiber: Processing fees may be repaired, but short - term absolute prices are dragged down by oil price drops. Suggest PF unilateral trading similar to PTA and expanding PF processing fees at low levels [18]. - Bottle chips: Supply has an incremental expectation, but short - term supply - demand contradiction is not prominent. Suggest PR unilateral trading similar to PTA and focus on expanding processing fees at the lower end of the 350 - 550 yuan/ton range [18]. Urea Industry - The inventory pressure of domestic urea factories is becoming more obvious, and the market may continue to oscillate and bottom. The downward space of the futures market depends on cost support. Future attention should be paid to inventory inflection points, export port collection trends, and coal price fluctuations [28]. Polyolefin Industry - PE: Overall trading is weak, but supply before early June is reduced due to maintenance and imports are low. Demand improves due to tariff cuts, and inventory is expected to decrease. - PP: Supply pressure increases after late May, but there is short - term demand support. Suggest unilateral short - selling on rallies and LP spreads expansion [31]. Crude Oil Industry - OPEC+ is discussing further production increases in July, and industry members are over - producing. US commercial crude inventories are accumulating, and gasoline and distillate demand is weak. Short - term oil prices will oscillate widely. Suggest a band - trading strategy, with WTI in the [59, 69] range, Brent in the [61, 71] range, and SC in the [450, 510] range. Consider buying volatility in the options market [75]. Styrene Industry - Crude oil price drops drag down the aromatics series. Styrene's recent rebound is weakening. Downstream 3S has high inventory, and raw material pure benzene supply - demand is not improving. Suggest a medium - term bearish view and focus on EB - BZ spread widening opportunities [81]. Methanol Industry - The inland methanol valuation has a downward pressure, production recovers after spring maintenance, and the port starts to accumulate inventory. The 09 contract is under pressure. Suggest short - selling MA09 on rallies [84]. Chlor - alkali Industry - Caustic soda: Short - term supply pressure is limited, demand from alumina is expected to increase, and spot prices are supported. However, non - aluminum demand pressure and cost reduction pose risks. Suggest unilateral wait - and - see. - PVC: The recent rebound is due to macro - stimulus, export support, and supply - demand balance. But in the long - term, there is an over - supply pressure due to the real estate situation. Suggest a medium - term short - selling strategy with a resistance level around 5100 for the 09 contract [89][91]. 3.

1. Report Industry Investment Rating No investment rating information is provided in the report. 2. Core Views - **LLDPE & PP**: The overall trading was weak on Monday, and market sentiment deteriorated. For plastics, maintenance increased and some production shifted before early June, with low imports. Demand improved in the short - term due to tariff cuts, and there was an expectation of inventory reduction. For PP, the maintenance peak was in late May, and subsequent supply pressure would increase. Demand had short - term benefits but mid - term concerns. The static fundamentals were okay. For single - side trading, it was advisable to go short on rallies, and the LP spread was expected to widen [4]. - **PVC & Caustic Soda**: For caustic soda, in the short - term, supply pressure was limited during the concentrated maintenance period. Demand was supported by the potential resumption of some alumina production and new production lines. The purchase price of mainstream Shandong factories increased, and the futures price might rise further, but there were risks. It was recommended to stay on the sidelines, and aggressive investors could try positive spreads cautiously. For PVC, the short - term rebound was supported by macro - stimulation, export, and supply - demand factors, but there was an over - supply pressure in the long - term. It was expected to fluctuate in the short - term, with a resistance level of around 5100 for the 09 contract [26]. - **Polyester Industry Chain**: For PX, short - term supply was tight, and demand was supported, but the upside was limited. PX09 was expected to fluctuate in the range of 6600 - 7000, and PX9 - 1 was in a short - term positive spread situation. For PTA, the supply - demand situation was expected to weaken. TA09 was expected to fluctuate in the range of 4600 - 5000, and TA9 - 1 was short - term positive spread and medium - term negative spread. For MEG, there was an expectation of inventory reduction, and short - term support was strong. It was advisable to sell put options on EG2509 - P - 4300 and go for positive spreads on EG9 - 1. For short - fiber, the absolute price was expected to adjust, and attention could be paid to the opportunity to widen the processing margin. For bottle - chips, the absolute price followed the raw materials, and attention could be paid to the opportunity to widen the processing margin at the lower end of the range [30]. - **Crude Oil**: Oil prices were oscillating, and the future logic would shift from macro to fundamental factors. If OPEC's actual production increase was as expected, the market would be under pressure; otherwise, the pressure would be relieved. There was still a short - term geopolitical premium. Oil prices were likely to fluctuate within a certain range. The recommended trading strategy was a band - trading approach, with the WTI range at [59, 69], Brent at [61, 71], and SC at [450, 510]. It was advisable to buy volatility in options trading [34]. - **Methanol**: The port inventory showed an inflection point, and the expected increase in imports would lead to inventory accumulation and a weaker basis. The 09 contract was expected to decline in the short - term, and it was advisable to add positions at 2350, targeting 2050 - 2100. It was also advisable to reduce short - positions on the 69 reverse spread [37]. - **Styrene**: Styrene rebounded strongly. Tariff cuts improved demand expectations, and the inventory was at a low level. However, there were risks, including high inventory in the 3S products and weak pure - benzene supply - demand. It was expected to fluctuate in the short - term and be bearish in the medium - term. Attention could be paid to the resistance level of 7800 - 7900 for the near - month contract, and the opportunity for the EB - BZ spread to widen [42]. 3.

Report Industry Investment Rating No relevant information provided. Report's Core View PVC and Caustic Soda - In the short term, the supply pressure of caustic soda is limited during the concentrated maintenance period, and the demand from the alumina sector has improved. Supported by fundamental supply - demand and positive macro - drivers, the spot price of caustic soda tends to be strong. However, attention should be paid to the price acceptance of non - aluminum sectors and the valuation of caustic soda. It is recommended to wait and see in the short term [7]. - For PVC, in the short term, the supply - demand contradiction is limited due to concentrated maintenance and limited inventory pressure. There is an expectation of rush - exporting PVC products. But in the medium and long term, there is an obvious over - supply pressure. It is recommended to wait and see, with a short - term rebound and a medium - term short - selling approach [7]. Polyester Industry Chain - For PX, in the short term, the supply is tight and the demand is supported, but the upward pressure on crude oil and the possible production cut of downstream products may put pressure on PX. It is recommended to treat it as a high - level shock, exit the PX09 - 1 positive spread, and pay attention to the reverse spread opportunity [12]. - For PTA, the short - term supply - demand is tight, but there is an expectation of weakening. It is recommended to treat it as a high - level shock, exit the TA09 - 1 positive spread at a high level, and pay attention to the reverse spread opportunity [12]. - For ethylene glycol, it is expected to reduce inventory in May, and it is recommended to take profit on the short - put option EG2509 - P - 4250 seller and conduct a long spread on EG9 - 1 [12]. - For short - fiber, the short - term inventory pressure is not large, but the processing fee is compressed. It is recommended to take the same strategy as PTA for single - side trading and expand the processing fee at a low level [12]. - For bottle - chips, the short - term supply - demand contradiction is not prominent, and the price follows the raw materials. It is recommended to pay attention to the opportunity of expanding the processing fee at the lower edge of the 350 - 550 yuan/ton range [12]. Styrene The short - term rebound of styrene is supported by low inventory and improved demand expectations. However, the high - production and high - inventory problems of 3S products and the poor supply - demand of pure benzene may limit the rebound height. It is recommended to pay attention to the resistance above 7800 - 7900 in the near - month [18]. Methanol The inland valuation of methanol has a downward pressure, the port starts the inventory - accumulation period, and the 09 contract is under pressure. It is recommended to short - sell the MA09 contract at a high level [22]. Crude Oil The overnight oil price continued to decline due to the progress of the US - Iran nuclear agreement negotiation. The short - term market will be mainly in a wide - range shock. It is recommended to wait and see in the short term and capture volatility - amplification opportunities in the option market [26]. PE and PP The spot sentiment of PE and PP has weakened. The supply pressure will gradually decrease in May, but the cost - end rebound compresses the profit. Attention should be paid to the restocking and exporting of plastic products [29]. Urea The core logic of the rise in urea futures is the boost of the clear export policy. The short - term supply - demand is expected to be tight, but the actual increase depends on the policy implementation and export orders. The short - term disk will be in a wide - range consolidation [90].

1. Report Industry Investment Ratings No industry investment ratings are provided in the reports. 2. Core Views Urea - Despite high daily production, short - term maintenance led to a decline in daily output. The new export policy allows the release of supportive export orders from May to June, and the upcoming summer top - dressing season in May - June is expected to boost agricultural demand. Market price increases are likely to be cautious, and the futures market is expected to fluctuate at a high level in the near term [3]. Crude Oil - Oil prices continued to rise, driven by the progress of China - US trade negotiations and geopolitical uncertainties. In the short term, the market risk appetite has increased, but no strong trend has been formed yet, and the sustainability of the macro - drive needs to be observed. The monthly - line fluctuation ranges are adjusted to [57, 67] for WTI, [60, 70] for Brent, and [450, 510] for SC [7]. Styrene - Crude oil is expected to be weak in the medium term, putting pressure on chemical products. Pure benzene supply has decreased recently, but overall supply pressure remains due to imports. Styrene downstream demand is weak, and supply is expected to increase. It is recommended to maintain a short - selling strategy for styrene, with the upper resistance for the near - term contract at 7300 [13]. PE and PP - For LLDPE, although imports are expected to decline significantly from May to June and supply pressure will gradually decrease, inventory pressure is still large under the situation of weak supply and demand, and there is a long - term downward risk. For PP, supply pressure eases slightly during the second - quarter maintenance season, but production is still high, demand is weakening, and there is also a long - term downward risk [17]. Caustic Soda - In the medium - to - long term, the demand for caustic soda from alumina is insufficient, and new production capacity is being added, so the supply - demand outlook is weak. In the short term, caustic soda is in the maintenance phase, and the price has been supported. It is recommended to maintain a short - selling strategy, with the near - term resistance at 2550 [26]. PVC - The supply - demand surplus of PVC is prominent. Domestic demand is weak, and exports are mainly based on price - for - volume. The long - term surplus problem is difficult to solve, and the price is expected to remain weak. It is recommended to short on rallies, but there is a risk of price rebound during the maintenance period [26]. Methanol - The inland valuation has a downward pressure. After the spring maintenance, production has recovered, and downstream profits are differentiated. The port has entered a stock - building period, and the MTO low - operation rate suppresses demand. It is recommended to short the MA09 contract on rallies [35][38]. Polyester Industry Chain - PX: Tight supply and short - term strong demand support its price, but the rebound space is limited. PX09 is expected to fluctuate strongly in the short term, and PX9 - 1 is in a short - term positive spread situation [40]. - PTA: The supply - demand pattern remains tight in the short term, and the price is expected to be relatively strong compared to oil prices, but the rebound is suppressed. TA09 is expected to fluctuate strongly in the short term, and TA9 - 1 is in a short - term positive spread and medium - term reverse spread situation [40]. - MEG: Domestic supply is expected to increase in May, but short - term de - stocking is expected due to high polyester load and reduced imports. EG09 is expected to be strong in the short term [40]. - Short - fiber: Inventory pressure is low in the short term, but the driving force is weaker than that of raw materials. The processing fee is under pressure, and the absolute price fluctuates with raw materials [40]. - Bottle - chip: Supply and demand are both strong in the short term, and the absolute price fluctuates with raw materials. The processing fee is supported, and the main - contract processing fee is expected to fluctuate between 350 - 550 yuan/ton [40]. 3.

1. Report Industry Investment Rating No relevant content provided. 2. Core Views of the Report - In the short term, OPEC's production increase has been fulfilled as scheduled. It is recommended that investors gradually take profits on dips, and it is not advisable to chase short positions excessively in the short term. In the current situation of low static inventory, going long on the positive spread on dips is still a good position [1]. - The domestic methanol supply is expected to continue to rise, imports will gradually increase, and traditional demand will gradually weaken. The supply - demand pattern will gradually weaken, and prices still face downward pressure. It is recommended to focus on short - selling on rallies for single - sided trading, and pay attention to reverse spreads for the 9 - 1 spread [3]. - For urea, it is expected that there will be some support at the bottom, and prices will tend to be strong. Traders with long positions at low levels can continue to hold, while those not in the market should wait for the market sentiment to cool down before considering long positions. The inter - month spread should focus on positive spreads on dips [5]. - Rubber prices have returned to range - bound trading. It is recommended to adopt a neutral approach and conduct short - term operations. Pay attention to the band - trading opportunity of going long on RU2601 and short on RU2509 [8][11]. - For styrene, pay attention to the opportunity of short - selling on rebounds [13]. - PVC is expected to fluctuate weakly in the short term due to the weak supply - demand situation [15]. - Polyethylene prices are expected to remain volatile in the short and medium term, while polypropylene prices are expected to fluctuate with a downward bias in May [17][18]. - PX and PTA are in the maintenance season, with short - term valuation support, but the upside of absolute prices is limited by weak crude oil. For ethylene glycol, the focus is on whether the inventory reduction expectation can be realized [20][21][22]. 3.
