1. Report Industry Investment Ratings - No specific industry - wide investment ratings are provided in the report. 2. Core Views PTA - The PTA balance shows less - than - expected destocking month - on - month. It maintains a tight balance in September, with minor current supply - demand contradictions. Attention should be paid to the lower support [5][50]. PX - PX is in a tight - balance state for the polyester industry. There are few changes in maintenance, and the balance pressure is low. It should be operated with low - level oscillations, and its elasticity comes from PXN [6][72]. Ethylene Glycol - Ethylene glycol has a record - low port inventory, and it is difficult to accumulate inventory in the short term. The existing supply is high. With new device commissioning plans, the short - term outlook is cautiously bullish, and it should be treated as a low - buying opportunity during oscillations [7][107]. 3. Summaries by Related Catalogs Attention to the Peak Demand Season Expectation - Terminal orders have shown partial improvement, and the weaving operation rate has slightly increased. The operation rates of texturing, weaving, and dyeing are 79% (+7%), 68% (+5%), and 72% (+5%) respectively. Downstream raw material inventory is 10 - 20 days, and orders have slightly improved.

US Lotte and Malaysia's Petronas restarted [72][84] - As of August 11, the ethylene glycol port inventory in the main ports of East China is about 50 tons, a decrease of 4.7 tons month - on - month. The current inventory is at a low level. From August 18 - 24, the actual arrival was 6.1 tons, and the port reduced inventory. From August 25 - 31, the expected arrival is about 5.4 tons, and the port is expected to slightly reduce inventory in the short term. Polyester factories' ethylene glycol raw material inventory days are 12 days [96] - Ethylene glycol has a strong current situation but weak expectations. The near - end low inventory has little pressure to accumulate, the coal - based load is at a high level. It is expected that existing devices will restart and new ones will be put into production in the fourth quarter. There is support from anti - involution and coal. Pay attention to reverse - spread opportunities [101]

Report Summary 1. Investment Ratings - No specific industry - wide investment ratings are provided in the report. 2. Core Views - The current supply - demand situation of the main varieties in the market shows different characteristics. For the livestock and soft commodities sectors, the supply of pigs is strong and demand is weak in the short - term, while the sugar market is in a state of weak oscillation. In the energy - chemical sector, the oil price has a complex supply - demand relationship and is expected to be under pressure in the medium - term, and the PVC market has marginal improvement in fundamentals but lacks a strong upward drive [1][2][4][5]. 3. Summary by Variety Livestock and Soft Commodities Sector - **Pig**: The short - term supply pressure is large, and the demand is not significantly boosted. The supply - demand pattern of strong supply and weak demand remains unchanged. The pig price center is moving down, and the 07 and 09 contracts on the futures market are still bearish. It presents a volatile pattern with limited upside and a bottom for downside. It is recommended that the breeding side sell out - of - the - money put options or participate in the cumulative sales option products [1][2]. - **Sugar**: Both the short - term and medium - term trends are weakly oscillating. International factors such as Brazil's new - season sugar supply increase and India's production reduction co - exist. Domestically, the production increase expectation has been fulfilled, and there may be additional imports. It is recommended to wait and see [3][4]. Energy - Chemical Sector - **Crude Oil**: In the short - term, pay attention to the phased rebound, and in the medium - term, it will run under pressure. The supply side has certain supporting factors, and the demand side has some positive signals, but the inventory situation is complex. It is recommended to buy futures contracts and buy put options for protection [4][5]. - **PVC**: It shows a range - bound oscillation in the short - term, and lacks an upward drive in the medium - term. The cost has rebounded, supply has increased slightly, demand has some speculative factors, and inventory has decreased. It is recommended to sell out - of - the - money put options on PVC at an appropriate time [6][7].
