1. Report Industry Investment Rating - PX: Trend is strong [1][5][6] - PTA: Cost support is strong [1][6] - MEG: Demand is weak, and unilateral price continues to decline, with a weak mid - term trend [1][5][6] 2. Core Viewpoints of the Report - PX: The unilateral price trend is strong, squeezing downstream profits. Despite the planned polyester factory production cuts, the expectation of tight PX supply cannot be falsified in the short - term, and the short - term trend is strong. Attention should be paid to long PX and short PF/PR/BZ/EB positions, as well as the 5 - 9 positive spread arbitrage [5][6] - PTA: With strong cost support, the unilateral trend is upward. It is recommended to hold long PTA and short PF/PR/MEG/BZ/EB positions and positive spread arbitrage. The tight PX supply provides cost support and continues to squeeze downstream profits. The short - term trend remains strong [6] - MEG: It is in a unilateral volatile market, and the mid - term trend is still weak. Polyester production cuts are negative for ethylene glycol demand, increasing the inventory accumulation. Attention should be paid to whether unplanned production cuts and overhauls can be implemented. The short - term trend is weak, and a short - position allocation is maintained [6] 3.
