Report Summary 1. Report Industry Investment Rating No information provided in the given content. 2. Report's Core Views - PTA: Near - end TA maintenance is over, and the start - up rate has increased. Polyester load has slightly risen, inventory is stable, the basis is weak, and spot processing fees are at a low level. PX domestic start - up has increased, and overseas plants have restarted. In the future, TA de - stocking will slow down, and long - term inventory accumulation is expected. However, processing fees are extremely low and have lasted for a long time. With the gradual return of PX supply, attention should be paid to the opportunity to expand processing fees under potential additional maintenance [1]. - MEG: Near - end domestic oil - based EG is stable, coal - based start - up has slightly increased, and overall load has recovered. Overseas, there are both maintenance and restarts. Port inventory has slightly accumulated. Downstream stocking levels have increased, the basis has weakened, and the benefit ratio has shrunk. New EG devices are put into operation earlier than expected, and valuations are significantly compressed. In the future, ports may start to gradually accumulate inventory, but the current inventory is not high, and valuations may be slowly compressed. Attention should be paid to the cost support of coal - based production [6]. - Polyester Staple Fiber: Near - end plants such as Sanfangxiang and Yizheng have increased their loads, and the start - up rate has reached 94.4%. Production and sales have improved, and inventory has slightly decreased. On the demand side, the start - up rate of the polyester yarn end is stable, raw material stocking has decreased, and finished product inventory has decreased. In the future, the rate of increasing the load at the polyester yarn end may slow down. The start - up rate of staple fiber is expected to remain high due to good spot benefits, and inventory pressure is limited. Processing fees are expected to fluctuate [6]. - Natural Rubber: National explicit inventory is stable, and the price of Thai cup lump rubber is stable. Rainfall has affected rubber tapping [6]. 3.
