1. Report Industry Investment Rating - Not provided in the document 2. Core View of the Report - This week, the confidence of long - position holders in natural rubber was frustrated, and the market is expected to be mainly in a volatile state before the holiday. Overseas raw material prices continued to decline slightly, weakening cost support. Although downstream enterprises stocked up before the holiday and inventory continued to decline, after the market's upward movement was blocked, long - position sentiment declined, and bearish sentiment increased, driving rubber prices to decline in a volatile manner [92]. 3.

Report Title - PX & PTA & MEG Strategy Report for September 2025 [1] Report Industry Investment Rating - Not provided in the given content Core Viewpoints - PX supply is expected to reach a high level in September, with short - process MX being abundant and new MX production adding to PX output. However, downstream TA maintenance is increasing, and with the continuous compression of TA processing fees, TA devices may have further maintenance. Thus, PX fundamentals are weak, and it may show a weak and volatile trend without significant crude oil fluctuations [150]. - For PTA, although the polyester operating load is rising and the fundamentals are improving, the price performance is weak, and the TA processing fee is still compressed below 200 yuan/ton. The "Golden September and Silver October" demand is facing challenges, with increasing external tariff risks. The TA price is expected to have support and show an overall volatile trend [150]. - MEG's operating load has climbed to a high level. In September, there are both maintenance and restart of devices. The port inventory is low, and the spot liquidity is tight. With supply contraction and demand increase, the port inventory is expected to remain low, and the short - term price may be volatile and strong [150]. Summary by Relevant Catalogs 1.

1. Report Industry Investment Rating There is no information provided regarding the report's industry investment rating. 2. Core Viewpoints of the Report - PX fundamentals maintain a weak balance, with obvious resilience in terminal demand. In the short - term, PX prices follow the cost of crude oil. In the future, during the peak seasons of "Golden September and Silver October", there is significant potential for demand and production to increase [139]. - For PTA, with large - scale device maintenance plans in August and new device production, the monthly output is expected to change little. Downstream demand provides resilient support. If oil prices are further pressured, TA prices will follow suit. Attention should be paid to demand recovery, tariff implementation progress, and significant oil price fluctuations [139]. - Regarding MEG, the supply is recovering well, and there is still room for domestic production to increase. The downstream demand provides resilient support. The inventory inflection point may arrive, and supply - demand will shift to inventory accumulation. Short - term prices are expected to be weakly adjusted, and subsequent attention should be paid to changes in coal and oil prices [139]. 3.

1. Report Industry Investment Rating - Not provided in the content 2. Core Viewpoints of the Report - The price of raw materials in the production areas is prone to rise and difficult to fall, with strong cost support. The downstream demand is average, and the acceptance of high prices is limited, resulting in light overall trading. The conflict between Thailand and Cambodia has a potential impact on the supply of natural rubber. Coupled with the continuous fermentation of anti - involution, the market sentiment was bullish last week. However, considering the impact of regulatory control measures on leading varieties and the overall market sentiment, it is expected that rubber may follow the overall market atmosphere and may have a narrow - range correction [76]. 3.
