Report Industry Investment Ratings No relevant content provided. Core Views Crude Oil - Overnight oil prices rose due to macro - factors such as a weaker US dollar and optimistic sentiment from US - China trade negotiations. OPEC + production increased in May, but less than planned. The market is in a strong - side shock trend, suggesting a short - term long - bias approach. Resistance levels are given for WTI, Brent, and SC. Options can use a straddle structure [2]. Polyester Industry - PX: Supply has increased, but short - term downside is limited due to downstream demand and geopolitical factors. Strategies include short - term observation, 9 - 1 short - spread, and narrowing the PX - SC spread. - PTA: Supply - demand is weakening, but there is support at low levels. Strategies are to focus on the 4600 support and use a short - on - rebound approach, and 9 - 1 short - spread. - Ethylene Glycol: Supply is expected to remain low in June, with good supply - demand structure but limited upside due to weak demand. It is expected to trade in a range, and look for 9 - 1 long - spread opportunities. - Short - fiber: Processing fee recovery is limited, and absolute price follows raw materials. Strategies are similar to PTA and expanding the processing fee at low levels. - Bottle - chip: Supply - demand is expected to improve in June, and the processing fee is supported. Strategies are similar to PTA and expanding the processing fee at the lower end of the 350 - 600 yuan/ton range [6]. Chlor - alkali Industry - Caustic Soda: Recent decline is due to cost reduction. Supply has increased overall, but decreased in Shandong. Demand is supported by alumina. Inventory is accumulating in East China. Hold the 7 - 9 long - spread before price cuts or large - scale warehouse - receipt outflows. - PVC: Short - term is in a shock trend, but long - term supply - demand contradiction is prominent. Supply pressure will increase in June, and demand is weak. Adopt a short - selling strategy [11][16]. Styrene Industry - Short - term styrene may fluctuate, and mid - term pay attention to the bearish opportunity from raw material resonance. Downstream 3S profits have improved, and port inventory has decreased slightly, but supply may increase after plant restart [19][22].

Supply and demand are balanced in June, with limited up - and - down drivers. - PP: New capacity will be put into operation in June - July, and demand is in the off - season. There is a large inventory - accumulation pressure. Adopt a short - selling strategy at high prices [26][27]. Urea Industry - High supply is not matched by demand. Agricultural demand has slightly improved but lacks activity, and industrial demand is weakened by the decline in compound fertilizer production. Future trends depend on export policy and market sentiment. [33] Methanol Industry - Supply is abundant with high domestic production and expected high imports. Demand has increased in MTO but with poor downstream profits. Price should be traded in the 2200 - 2350 range, and pay attention to the transition from implicit to explicit inventory accumulation [35].
