1. Report Industry Investment Rating No information provided in the documents. 2. Core Views of the Report - PTA: The start - up of PTA devices has rebounded slightly, polyester load has increased, inventory has continued to decline, basis has weakened month - on - month, and spot processing fees have declined. PX domestic start - up is stable, overseas devices are restarted, PXN has weakened month - on - month. Although TA inventory continues to decline, its structure and efficiency are still weakening. Considering the lack of unexpected performance in polyester and subsequent new production, there is an expectation of inventory accumulation in the far - month. However, the processing fee has reached a very low level, and PX supply is gradually recovering. One can pay attention to the opportunity of expanding the processing fee at low prices [1]. - MEG: Recently, domestic oil - based production has increased the load, coal - based start - up has slightly declined, the overall load has decreased, overseas maintenance has increased. At the beginning of the week, port inventory continued to decline, and the arrival of goods within the week has rebounded. Downstream inventory levels have decreased, and the basis has strengthened month - on - month. There is an expectation of inventory accumulation in the far - month due to the return of maintenance and the commissioning of new devices. The pattern is not bad, and the profit level is also considerable. It is expected to fluctuate in a relatively wide range. One should pay attention to the restart progress of Satellite and Xinrun [8]. - Polyester Staple Fiber: Recently, the start - up of Xin凤鸣, Times Hollow, and Zhongtai has increased, and the start - up rate has reached 93.9%. Sales have weakened month - on - month, and inventory has remained stable month - on - month. On the demand side, the start - up of the polyester yarn end has slightly increased, raw material inventory has rebounded, and finished product inventory has continued to accumulate, with weak efficiency. In the future, the start - up rate of the polyester yarn end may slow down after the accumulation of finished product inventory. It is expected that the start - up will remain high under the good spot efficiency of staple fiber, and the processing fee is expected to fluctuate [8]. - Natural Rubber: The national explicit inventory remains stable at an absolute level, and the price of Thai cup rubber remains stable. The strategy is to wait and see [8]. 3.
