Report Summary 1. Report Industry Investment Rating No relevant information provided. 2. Core Views - For PTA, with some near - end TA devices under maintenance,开工 decreasing, polyester load rising, inventory decreasing, basis strengthening slightly, and spot processing fees improving. PX domestic operation rate increases while some overseas devices reduce load. TA is expected to maintain high maintenance, downstream shows no obvious pressure, and with India's revocation of BIS certification, TA inventory accumulation slope is not high. There are opportunities for positive spread at low prices and expanding processing fees [2]. - For MEG, near - end domestic oil - based production increases load, coal - based production has some maintenance and load reduction, overall operation rate drops, overseas device restart is postponed, port inventory accumulates. In the future, inventory accumulation speed is expected to slow down, and there are short - term opportunities for selling put options, but the long - term pattern is expected to be weak [2]. - For polyester staple fiber, near - end device operation is stable, production and sales improve slightly, inventory is basically flat. In the future, demand remains stable, short - term inventory pressure is limited, but the pattern may weaken in the long - term, and attention should be paid to the situation of warehouse receipts [2]. - For natural rubber and 20 - grade rubber, the national explicit inventory is stable and at a relatively low level, Thai cup - lump rubber price is stable, and rainfall affects tapping. The strategy is to wait and see [5]. 3.

Report Industry Investment Rating No relevant information provided. Core Viewpoints - For PTA, the near - term TA partial device load reduction leads to a slight decline in start - up, while polyester load increases, inventory accumulates slightly, and the basis strengthens. PX domestic start - up recovers, and PXN expands. Considering the long - term low processing fees and improved terminal data, the processing fee center may gradually recover [2]. - For MEG, the near - term domestic oil - based restart and overseas device restart lead to a decline in port inventory at the beginning of the week, but the long - term pattern is bearish due to high inventory. However, there may be negative feedback on the supply side after the decline in coal - based benefits, and attention should be paid to coal - based cost support [3]. - For polyester staple fiber, the near - term restart of Fujian Shanli increases the start - up, but sales decline. The overall efficiency and start - up of the polyester yarn end have not improved significantly. With high exports and good spot efficiency, the overall inventory pressure is limited, and attention should be paid to the opportunity of expanding processing fees and warehouse receipts [3]. - For natural rubber and 20 - grade rubber, the national explicit inventory is stable at a relatively low level, and the Thai cup - rubber price is stable with rainfall affecting tapping. The strategy is to wait and see [6].
