1. Report Industry Investment Rating - No relevant content provided 2. Core Views of the Report - For PTA, the supply has recently returned, and with some major suppliers selling goods, the spot market liquidity is fair. The market supply - demand outlook is weak, and the spot basis is gradually declining. PTA spot prices mainly fluctuate following the cost side. Attention should be paid to polyester upstream - downstream device changes and terminal demand [5]. - For MEG, the port inventory increased slightly this week, but it's unlikely to be persistent this month. Due to pre - holiday stocking, polyester factories still have demand for low - price restocking. In the short term, MEG supply - demand remains tight, and the basis has some support during the delivery period. However, with the progress of new device commissioning, the supply - demand will turn loose in the far - month, and the futures price is under pressure. Attention should be paid to device changes [7]. 3.
