Report Industry Investment Rating - The report does not explicitly mention the industry investment rating. Core Viewpoints - The trends of p-xylene (PX), purified terephthalic acid (PTA), and monoethylene glycol (MEG) continue to be strong due to ongoing geopolitical impacts [1]. - PX: The unilateral trend is strong, and the price center may continue to rise. Reduce the 5 - 9 month spread, hold the basis positive spread, and go long on PX and short on polyester staple fiber (PF). The cost support for PX remains strong, and both domestic supply and imports are expected to decline significantly [8]. - PTA: Go long on PX and short on PTA. The unilateral trend is strong. Reduce the 5 - 9 month spread and hold the basis positive spread. Affected by geopolitical conflicts, the cost - end of crude oil and PX is expected to rise. PTA is in general supply - demand balance, and inventory reduction will start from April [9]. - MEG: The unilateral trend is strong. Continue to hold the MEG5 - 9 positive spread. The domestic load of ethylene glycol has significantly declined, and the import volume is expected to decrease [9][10].

The Asian p - xylene price continued to rise on March 6 due to the escalation of the Middle - East conflict [2][3]. - Supply and Demand: The PX operating rate in Asia has slightly declined to 83% but remains at a high level. The downstream PTA supply is generally loose. The PX operating rate in China on March 5 was 84%, lower than 89% on February 27 [5][8].
