1. Report Industry Investment Rating - Not provided in the given content 2. Core Viewpoints - For PTA, in the short - term, it is recommended to wait and see; in the medium - to - long - term, it is recommended to hold long positions. The raw material PX reduction is slowing down, but further production cuts are likely due to logistics blockade. The downstream polyester's load - increasing slows down and may cut production, but the overall is expected to maintain de - stocking [3]. - For MEG, due to concerns about the stability of Saudi Arabian device operation and possible increase in export/trans - shipment trade, the arrival volume is expected to decline rapidly under continuous Middle - East logistics blockade. The short - term de - stocking speed will accelerate, and the far - month balance sheet has high uncertainty, so it is recommended to wait and see [10]. - For polyester staple fiber, with raw materials strengthening, the terminal is more hesitant. The raw - to - recycled price difference strengthens, and the recycled substitution effect is obvious. Although the processing fee is acceptable, the future production may be limited by raw material supply. The current valuation is relatively neutral under the weak supply - demand situation [10]. - For natural rubber and 20 - grade rubber, the main strategy is to wait and see [10]. 3.
