1. Report Industry Investment Ratings No relevant content provided. 2. Report Core Views Crude Oil - International oil prices rose, mainly driven by macro and supply - side factors boosting market risk appetite. In the short - term, the upward trend of the market is due to supply expectation adjustments and macro - geopolitical impacts on market sentiment. In the long - term, the balance sheet may continue to loosen. It is recommended to wait for short - selling opportunities on rallies. The expected price ranges are [59, 69] for WTI, [61, 71] for Brent, and [440, 500] for SC. Options can consider buying straddle structures [2]. Methanol - The methanol market is facing significant inventory accumulation pressure. The 09 contract is mainly priced based on the oversupply situation in the inland area. The market will continue to force production cuts. The price will continue to decline in an oscillatory manner, with short - term resistance around 2270 and a medium - term target of 2050 - 2100 [5]. Styrene - Although OPEC+ has a strong production increase expectation, geopolitical risks and seasonal factors support oil prices in the short - term. The supply of pure benzene is expected to be high in June, and the cost support for styrene is weak. With the improvement of styrene industry profits, supply is expected to increase while demand is weak, so styrene prices are under pressure. It is advisable to take a short - selling approach [9]. Polyolefins - In the plastics market, the supply of PE may see inventory reduction in early June due to increased maintenance and less imports, while the supply pressure of PP will increase as maintenance ends. The demand lacks sustainability. It is recommended to short - sell PP on rallies and consider expanding the LP spread [13]. Caustic Soda and PVC - For caustic soda, the supply - side contradiction is limited in June, and some enterprises want to support prices. The demand from the alumina industry provides strong support for the spot price. It is advisable to consider expanding the spread between the near - month and 09 contracts. For PVC, the long - term supply - demand contradiction is prominent, and the short - term supply pressure will increase. It is recommended to short - sell PVC on rallies, with an expected price range of 4500 - 5000 [38]. Urea - The core contradiction of urea lies in the continuous impact of high supply and weak demand. The supply is abundant, and the demand is in the off - season. After the Dragon Boat Festival, if agricultural fertilizer procurement fails to start effectively and the export volume is low, the price may decline [41]. Polyester Industry Chain - PX: Supply is increasing, and demand may weaken. It is expected to oscillate in the range of 6500 - 6900, and consider reverse spreads for PX9 - 1 and narrowing the PX - SC spread. - PTA: Supply - demand is marginally weakening, but short - term support is strong. It is expected to oscillate in the range of 4600 - 4900, and consider reverse spreads for TA9 - 1. - MEG: The supply - demand structure in June is good, with inventory reduction expectations. Consider buying EG09 around 4200 and positive spreads for EG9 - 1. - Short - fiber: The driving force is weaker than the raw material end. The strategy is similar to PTA for single - side trading, and expand the processing fee at a low level. - Bottle - chip: The supply - demand is expected to improve in June, and consider expanding the processing fee at the lower end of the 350 - 600 yuan/ton range [44]. 3.
