Views and Suggestions - PX: Conduct month - spread positive arbitrage and short PXN at high levels. The supply - demand pattern of PX is tight due to the upcoming commissioning of Sanfangxiang's 3 million - ton PTA plant and the planned maintenance of South Korea's Hanwha's 1.2 million - ton PX plant in August. PXN is at a high valuation and shows a weakening trend [7]. - PTA: Perform month - spread reverse arbitrage operations. The basis has dropped significantly, factories are selling, and traders' positive arbitrage positions are being stopped out. Supply will be marginally looser from mid - July, and it is expected that PTA will continue to accumulate inventory with increasing supply and decreasing demand [7]. - MEG: Due to the strong coal price at the cost end, relevant coal - chemical products have rebounded. With a low valuation, conduct basis and month - spread positive arbitrage and avoid chasing short positions [7].
