1. Report Industry Investment Ratings No relevant content provided. 2. Core Views of the Report Crude Oil - Overnight oil prices rose slightly, maintaining a range - bound trend. The market is influenced by macro - geopolitical factors and supply marginal increments. The US trade court's ruling on Trump's global tariff policy and potential sanctions on Russia, along with OPEC + supply policies, are key factors. Demand is constrained by global trade frictions. Short - term, oil prices are expected to remain volatile, and breakthroughs require clarity on OPEC + production decisions and EU - US tariff games. Mid - to long - term, a band - trading strategy is recommended, and short - term, there are opportunities to short on rebounds. Suggested price ranges are [59, 69] for WTI, [61, 71] for Brent, and [440, 500] for SC. Attention should be paid to INE spread rebound opportunities and options to buy volatility during range - bound periods [2]. PVC and Caustic Soda - Caustic Soda: In the short term, supply pressure is limited during the concentrated maintenance period. Demand from the alumina industry is expected to increase due to profit improvement and new production lines. However, non - aluminum demand pressure and cost decline pose risks. It is recommended to wait and see on single - side trades and attempt a 6 - 9 spread long position [7]. - PVC: Recently, PVC has been weak due to poor market sentiment. Fundamentally, long - term contradictions are prominent as real - estate demand remains sluggish, and exports face potential negative impacts. In the near term, supply pressure is limited during the maintenance period, and exports may remain positive due to BIS extension. PVC is expected to remain weak in the short term, and a mid - term short - selling strategy is recommended with resistance around 5100 for the 09 contract [7]. Polyolefins (PE and PP) - Spot prices continue to fall, but trading volume has improved. The overall market sentiment is pessimistic. For PE, maintenance will increase before early June, imports are low, and inventory is expected to decrease. For PP, supply pressure will increase after the maintenance peak in late May. Demand lacks sustainability after a round of restocking. It is recommended to short PP on rallies and expect the LP spread to widen [12]. Styrene - After the styrene delivery, short - covering cooled down, and the basis declined. The weak commodity market and inventory increases of pure benzene and styrene at the docks put downward pressure on the pure benzene market. The new - cycle port inventory of styrene has started to accumulate, increasing the pressure on high - price supplies. In the medium term, the low - profit situation of 3S products provides limited support for styrene, and Sino - US tariff disputes will negatively affect terminal demand. However, the overnight crude oil rebound may impact the chemical market. It is recommended to wait and see in the short term and be bearish on styrene in the medium term [18]. Urea - The market is currently weak due to increased inventory pressure during the demand lull. If export - reserved inventory cannot be quickly digested, it will further intensify spot pressure. Urea exports are a potential turning point, depending on Middle East and South American procurement demand and export policies. If orders exceed expectations, inventory pressure may be relieved; otherwise, the market will remain loose [26]. Polyester Industry Chain - PX: Supply is increasing as some domestic and foreign devices resume production. Downstream PTA load is rising, and the short - term supply - demand situation is still good. Spot supplies are tight, and foreign buyers are supporting prices. PX is expected to oscillate between 6500 - 6800 in the short term, with strong support at the lower end. A 9 - 1 spread short position can be attempted, and the PX - SC spread can be narrowed [29]. - PTA: In late May, PTA devices restarted, and the supply - demand situation is weakening due to strong polyester factory减产 sentiment. Cost support is limited, but low processing fees provide some support. PTA is expected to oscillate between 4600 - 4800 in the short term, with strong support at the lower end. A 9 - 1 spread short position is recommended [29]. - Ethylene Glycol: Despite polyester减产 expectations, supply is expected to contract due to domestic and overseas device maintenance. Port inventory is decreasing, and de - stocking may accelerate in June. It is recommended to wait and see on single - side trades and attempt a 9 - 1 spread long position [29]. - Short - fiber: Processing fees are under pressure, and some factories plan to reduce production. Raw material PTA supply - demand is weakening. Short - fiber processing fees may recover, and the absolute price will follow raw materials. Attention should be paid to factory production cuts. The strategy is similar to PTA for single - side trades, and processing fees can be widened at low levels [29]. - Bottle - grade PET: Supply is expected to increase, but demand from the downstream soft - drink industry will rise during the peak consumption season. The short - term supply - demand contradiction is not significant. The absolute price will follow raw materials, and attention should be paid to device operation under low processing fees. The strategy is similar to PTA for single - side trades, and processing fees are expected to range between 350 - 550 yuan/ton, with opportunities to widen at the lower end [29]. Methanol - Fundamentally, inland methanol has a downward valuation pressure. After the spring maintenance, production has increased, and downstream profits are differentiated. The port has entered a inventory - accumulation period, with May imports expected to reach 110 million tons. Iranian supply increments and positive import profits strengthen arrival expectations. MTO low - operation restricts demand, and the 09 contract is under pressure. It is recommended to short the MA09 contract on rallies, as the mid - to long - term supply - demand contradiction remains unresolved, and the rebound space is limited under inventory - accumulation expectations [38][40]. 3.

Report Industry Investment Ratings No information regarding report industry investment ratings is provided in the content. Core Views of the Report Chlor - Alkali Industry - **Caustic Soda**: Short - term supply pressure is limited during the concentrated maintenance period. Demand from the alumina industry is expected to increase. However, there are risks from non - aluminum demand pressure and rising valuations after cost reduction. It is recommended to wait and see on the single - side and try positive spreads for the 6 - 9 contracts [7]. - **PVC**: The recent rebound is due to macro - stimulus, export support, and supply - demand factors. But in the long - term, there is an obvious oversupply pressure, and potential negative factors exist. It is suggested to wait and see in the short - term and maintain a short - selling idea in the medium - term, with a resistance level of around 5100 for the 09 contract [7]. Crude Oil Industry - International oil prices are in a volatile trend, lacking strong drivers. The market is mainly affected by macro and supply factors. Short - term prices will continue to fluctuate, and the implied volatility is rising. In the medium - to - long - term, a trading - band strategy is recommended, and short - selling opportunities on rebounds can be observed. Attention should also be paid to the INE spread rebound opportunities and options' volatility - trading opportunities [12]. Styrene Industry - The recent rebound of styrene is due to tariff relief and low - inventory support. But high - price spot shows signs of weakness, and there are problems in the downstream and raw - material supply. It is expected to have more downward space, and the strategy is to short - sell at a high price around 7800 for the near - month contracts and pay attention to the widening opportunity of the EB - BZ spread [23]. Polyester Industry - **PX**: Supply is increasing, and the supply - demand situation is marginally weakening. It is relatively resistant to decline in the short - term. The strategy is to pay attention to the support at 6500 - 6600 and try a reverse spread for the 9 - 1 contracts [27]. - **PTA**: Supply - demand is marginally weakening, and the basis has declined. It is also relatively resistant to decline. The strategy is to pay attention to the support at 4600 and take a reverse - spread approach for the 9 - 1 contracts [27]. - **Ethylene Glycol (MEG)**: Supply is expected to contract, and inventory is decreasing. The strategy is to wait and see on the single - side and try a positive spread for the 9 - 1 contracts at a low price [27]. - **Short - fiber**: The processing fee may be repaired. The strategy is the same as PTA for the single - side, and the processing fee should be expanded at a low level [27]. - **Polyester Bottle - chip**: Supply and demand are both increasing, and the processing fee is low. The strategy is the same as PTA for the single - side, and the processing fee should be expanded at the lower limit of the 350 - 550 yuan/ton range [27]. Polyolefin Industry - For LLDPE and PP, the supply of LLDPE is expected to decrease in inventory before early June, while the supply pressure of PP will increase after late May. Demand lacks sustainability. The strategy is to short - sell PP at a high price and pay attention to the expansion of the LP spread [31]. Methanol Industry - The port inventory is at a turning point, and the supply is increasing while the demand is in the off - season. The 09 contract's supply - demand situation is more relaxed. The strategy is to short - sell around 2300 - 2350 with a target of around 2100, and the MTO spread should be operated within 0 - 500 [34]. Urea Industry - The supply is at a high level, while the demand is under pressure from the decline of compound - fertilizer plants and stagnant agricultural fertilization. The short - term market is likely to move in a range after the decline [38].
