1. Report Industry Investment Rating No relevant content provided. 2. Core Views of the Report - PTA: The PTA futures rose and then fell yesterday, with a general negotiation atmosphere in the spot market and a slightly stronger spot basis. Some polyester factories restocked. The processing margin has remained low recently, some PTA plants are under maintenance, and the polyester load has rebounded. There is no pressure for PTA to accumulate inventory in August. However, the oil price is 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 the oil price and the changes in upstream and downstream plants [5]. - MEG: On Tuesday, the price center of ethylene glycol (MEG) rose steadily, and the market negotiation was fair. The polyester load rebounded to around 89.4% last week, and the load of looms and texturing machines also increased, with gradually strengthening demand support. During the recent price correction of MEG, polyester factories actively participated in price - fixing, and the port shipments will improve in the future. The inventory at ports is not expected to increase significantly from August to September. It is expected that the price center of MEG will be adjusted within a range in the short term. Attention should be paid to the rebound speed of the polyester load and the commodity trend [7]. 3.

1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - The supply - demand situation of industrial silicon and polysilicon is complex. For industrial silicon, there is an issue of supply exceeding demand, with the supply side having increased production last week, while demand has been continuously sluggish. For polysilicon, the supply side is also relatively strong, and the demand recovery is at a low level [6][8][9]. - The cost support of industrial silicon is expected to increase, and it is predicted to fluctuate in the range of 8165 - 8555 for the 2509 contract.
