1. Report Industry Investment Rating - No relevant content provided 2. Core Views of the Report - For PTA, the post - holiday spot market negotiation atmosphere is average, with spot basis fluctuating. Due to some PTA device maintenance and production reduction, along with the delay of new device commissioning, the PTA supply - demand outlook improves. It is expected that the short - term spot price will mainly fluctuate following the cost side. Attention should be paid to downstream production and sales and device changes [5]. - For MEG, the main port arrivals this week are still high, and it is expected that the port inventory will continue to rise early next week. In October, the MEG supply - demand pattern turns to inventory accumulation, with an overall accumulation of about 50,000 tons, and there is continuous inventory accumulation pressure in the far - month. The market sentiment is under significant pressure. It is expected that the MEG market will operate weakly in the short term, and attention should be paid to external factors and device changes [7]. 3.

Group 1: Investment Rating - No investment rating for the industry is provided in the report. Group 2: Core View - The polyolefin market saw a rally followed by a decline. From a fundamental perspective, the polyolefin spot market is still driven by supply and demand. Currently, PE inventory is being slowly digested, and PP inventory has also improved. After continuous declines, short - selling pressure has been released. With the stabilization of crude oil prices, it provides support for chemical products. The market also rebounded after continuous declines. In the short term, the recovery of terminal demand may support the market to oscillate and rebound. Future attention should be paid to the potential rebound after the market stabilizes and the situation of the Fed meeting this week [2].

Report Industry Investment Rating - The report gives a neutral rating for PX/PTA/PF/PR and suggests to focus on the Sheng Hong PX plant situation [5]. Core Viewpoints - On Thursday, oil prices dropped significantly as Brent fell below $67 per barrel again due to OPEC considering further lifting production restrictions. The impact of the latest OPEC news on the oil market is more emotional, and the short - term direction of oil prices is unclear considering uncertainties like Russia - Ukraine peace talks. Naphtha has been strong recently due to supply disruptions and expected demand recovery [1][2]. - In the PX market, after the restart of Idemitsu's maintenance plant in early September and the future restart of Fuhai Chuang, the PX load at home and abroad is expected to rise. The PX balance sheet has shifted from destocking to a loose balance, and the floating price of near - month PX has weakened, but PXN has support at the bottom due to low inventory and new PTA plant demand [2]. - In the PTA market, the actual maintenance volume of Hengli Huizhou's 5 million - ton PTA plant is less than expected and may restart ahead of schedule, narrowing the destocking range in September. The spot basis has weakened, and the demand recovery is limited with insufficient order connections [3]. - In the demand aspect, the polyester operating rate is 90.3% (up 0.3% month - on - month). There are signs of demand recovery, but this week's order connections are insufficient, and the weaving and texturing loads have declined. The polyester load is expected to continue to rise steadily in the short term [3]. - For PF, the spot production profit is 117 yuan/ton (unchanged month - on - month). The load has increased as some previously reduced - production plants have resumed, and the overall supply - demand situation has improved with inventory destocking, but there is obvious wait - and - see sentiment [3]. - For PR, the bottle - chip spot processing fee is 425 yuan/ton (up 17 yuan/ton month - on - month). The fundamentals have changed little, and the industry is expected to maintain a 20% production reduction target in September, with limited subsequent load increase and expected small fluctuations in processing fees [4].
