1. Report Industry Investment Rating - No relevant content provided 2. Core Viewpoints of the Report - For PTA, the short - term processing margin remains low, some PTA devices are under maintenance, and polyester load is rising, so there is no pressure for inventory accumulation in August. However, oil prices are under pressure, and the cost side lacks support. It is expected that the PTA spot price will fluctuate in the short term, and the spot basis will fluctuate within a range. Attention should be paid to the impact of the US - Russia talks on oil prices and changes in upstream and downstream devices [5]. - For MEG, last week, the polyester load rebounded to around 89.4%, and the load of looms and texturing machines also increased, so the demand support is gradually strengthening. During the recent price correction of MEG, polyester factories actively participated in pricing, and the port shipments will improve. The port inventory is not expected to rise significantly from August to September. It is expected that the MEG price will adjust within a range in the short term, and attention should be paid to the rebound speed of polyester load and commodity trends [6]. - The short - term commodity market is greatly affected by the macro - level. Attention should be paid to the cost side, and the upper resistance level should be monitored for the market rebound [9]. 3.

1. Report Industry Investment Rating No information provided in the content. 2. Core Views of the Report - PTA: The PTA futures fluctuated and declined yesterday, with the spot market negotiation atmosphere being average and the spot basis stabilizing. The recent macro - atmosphere has cooled down, commodities have corrected, the cost - side support is insufficient, and the downstream terminal demand is weak in the off - season. Although there have been many changes in PTA devices recently, the spot market liquidity is relatively abundant, and there is a lack of upward driving force for PTA. However, as the basis weakens, the buying sentiment of traders has slightly recovered, and the downward space is limited. Also, the PTA processing margin was once compressed below 200 this week, and attention should be paid to whether there are new variables in PTA devices under continuous low processing fees [5]. - MEG: On Thursday, the price center of ethylene glycol fluctuated downward, and the basis weakened. It is expected that the visible inventory of ethylene glycol may show a phased increase this week. In August, the fundamentals of ethylene glycol are mainly in a loose balance. The restart of Zhejiang Petrochemical Phase II 1 is moderately postponed to around the middle of the month, and the increase in domestic output is delayed. It is expected that ethylene glycol will be mainly adjusted in a wide range in the short term. Currently, the port inventory is low, and attention should be paid to the cost - side and device changes [7]. 3.
