Report Summary 1. Report Industry Investment Rating No relevant information provided. 2. Report Core Views - For PTA, with low processing fees leading to more additional maintenance, and polyester demand expected to stabilize and have upward flexibility, there is a chance to expand processing fees by buying at low prices [3]. - For MEG, the short - term inventory accumulation pressure is small, and the port inventory is expected to remain low. It is expected to fluctuate widely, and attention should be paid to the restart progress of satellite plants [15]. - For polyester staple fiber, as the downstream inventory is continuously reduced, the downstream start - up may continue to rise. Considering the low processing fees, there is an opportunity to expand processing fees by buying at low prices [15]. - For natural rubber and 20 - number rubber, the national explicit inventory remains stable with no seasonal decline, and the Thai cup - rubber price rebounds due to rainfall affecting tapping. The strategy is to wait and see [15]. 3.
