Report Summary 1. Industry Investment Rating - No industry investment rating information is provided in the report. 2. Core Viewpoints - For PTA, commodity sentiment has improved, domestic PTA production capacity supply has contracted, port inventory has declined, and a large number of warehouse receipts are being canceled. The spread between PX and naphtha has expanded to around $250, and the profit margins of alkyl transfer and TDP are not optimistic. The spread between PX and MX remains at around $90. In July, bottle chips and staple fibers are about to enter the maintenance cycle. The port inventory in the market has decreased, and polyester replenishment has improved under the weakening basis. The basis of PTA has rebounded from 0 to 30. The maintenance of mainstream PTA factories has significantly boosted the market [2]. - For ethylene glycol, coal prices have rebounded, ethylene glycol prices have increased, and macro - sentiment has improved significantly. Overseas ethylene glycol plants, especially those in Saudi Arabia, have continuously postponed maintenance, which may have a significant impact on the future market. The future arrival volume of ethylene glycol has decreased. Polyester production and sales have weakened, and polyester has entered the maintenance cycle. Due to the rapid increase in polyester prices, the downstream weaving profit has shrunk, and the terminal load has significantly declined, which has a certain negative impact on the market [2]. 3.
