1. Report Industry Investment Ratings - Urea: ★☆☆ (One star, indicating a bullish/bearish bias, with a driving force for price increase/decrease, but limited operability in the market) [1] - Methanol: ★☆☆ [1] - Styrene: ☆☆☆ (White star, suggesting a relatively balanced short - term trend and poor market operability, with a wait - and - see approach) [1] - Polypropylene: ★☆☆ [1] - Plastic: ★★★ (Three stars, representing a clearer bullish/bearish trend and a relatively appropriate investment opportunity currently) [1] - PVC: ★☆☆ [1] - Caustic Soda: ★☆☆ [1] - PTA: ★☆☆ [1] - Ethylene Glycol: ★☆☆ [1] - Short - fiber: ★☆☆ [1] - Glass: ★☆☆ [1] - Soda Ash: ★☆☆ [1] - Bottle Chips: ★☆☆ [1] - Propylene: ★☆☆ [1] 2. Core Views - The overall chemical futures market is in a complex situation, with different products showing various trends and drivers. Some products are affected by supply - demand fundamentals, while others are influenced by policy, cost, and geopolitical factors. The market is generally in a state of shock, and different products have different investment opportunities and risks [2][3][5] 3. Summary by Relevant Catalogs 3.1 Olefins - Polyolefins - Both olefin and polyolefin futures contracts closed down in intraday trading. The supply of domestic olefins tightened due to individual plant shutdowns, but weak downstream demand restricted the buying pace. For polyethylene, inventory was smoothly reduced, but the overall downstream operating rate declined slightly, and demand support is expected to weaken. For polypropylene, although there is policy support, demand is weak as downstream factories have completed year - end orders, and the future demand has been pre - consumed [2] 3.2 Polyester - PX and PTA prices fluctuated in the morning and rose rapidly in the afternoon, mainly driven by sentiment due to a rumored unplanned maintenance of a PK plant in the second quarter. Before and after the Spring Festival, demand weakens, and there is limited upward driving force. In the second quarter, there are opportunities for PX processing margin to go long on dips and for positive spreads after the spread narrows, subject to downstream demand. For ethylene glycol, domestic new plants are put into production while overseas plants shut down, with expected supply increase at home and decrease abroad. There is a risk of inventory accumulation in the future, but the supply - demand situation may improve in the second quarter. Short - fiber is mainly driven by cost, and attention should be paid to downstream stocking rhythm around the Spring Festival. Bottle chips' processing margin has recovered, but long - term capacity pressure remains [3] 3.3 Pure Benzene - Styrene - The pure benzene futures market adjusted in shock, while the spot price continued to rise. Supply decreased due to refinery production cuts and reduced imports, and demand increased, leading to significant inventory reduction at East China ports. The short - term market is expected to be strong in shock. The styrene futures market consolidated in intraday trading. The current supply - demand balance is tight, with limited port arrivals and expected further inventory reduction. Domestic producers' sales are good, and exports provide some support [5] 3.4 Coal Chemical Industry - The methanol market continued to decline. Import arrivals decreased significantly, but demand decreased due to plant shutdowns and reduced loads, and the inventory reduction speed is expected to slow down. Although there is support from the expected significant reduction in imports in the first quarter, the short - term market is expected to be in a stalemate. Urea prices are weakly stable. Daily production has recovered, downstream demand has increased, and production enterprises are reducing inventory. In the short term, the market may decline slightly, but in the long term, it is likely to fluctuate strongly within a range [6] 3.5 Chlor - alkali Industry - PVC showed an intraday shock trend. The cost pressure of ethylene - based PVC decreased, while that of calcium carbide - based PVC increased. The operating rate of some enterprises decreased, and the export volume was affected by price changes. It is expected that the price center will rise, and the strategy is to go long on dips. Caustic soda continued to be weak, with high inventory pressure. Although the price of liquid chlorine is strong and the integrated profit is acceptable, the industry is generally in a loss, and the future production reduction needs to be continuously monitored [7] 3.6 Soda Ash - Glass - Soda ash is operating weakly. Although the weekly inventory has decreased slightly, the overall pressure is still large. Supply pressure is high in the long term, and downstream procurement sentiment is poor. The strategy is to go short on rebounds and wait and see when the price drops near the cost. Glass futures prices have declined. Affected by weather and approaching the holiday, inventory may accumulate. The industry is losing money, but there is a rumor of new production line ignition, and supply may increase slightly. In the long term, the industry needs to reduce capacity. When the futures price drops to around 1000 yuan, there may be a long - buying opportunity [8]

Some products face supply shortages, while others are affected by cost, demand, and policy factors [2][3][5] - There are risks such as demand shrinkage due to downstream profit pressure and supply - demand imbalance in the market, and at the same time, there are also potential investment opportunities in some products [2][5] Summary by Directory Olefins - Polyolefins - Propylene futures declined, with tight supply in the short term and limited support from the demand side due to high raw material costs. There is a risk of demand shrinkage [2] - Plastic and polypropylene futures were volatile. For polyethylene, inventory was smoothly reduced, but demand support is expected to weaken. For polypropylene, although there is policy support, demand has been pre - consumed, and the upward - driving force for supply - demand fundamentals is insufficient [2] Pure Benzene - Styrene - Pure benzene prices rose due to port de - stocking and refinery production cuts. The short - term market is expected to be volatile and strong [3] - Styrene futures rose. The market is in a tight - balance state, with expected port de - stocking, low enterprise inventory, and export support [3] Polyester - PX and PTA prices are expected to decline due to weak cost support and inventory accumulation. There may be investment opportunities in the second quarter, but it depends on downstream demand [5] - Ethylene glycol is affected by new domestic production and overseas shutdowns. There may be short - term improvement in the second quarter, but it is under long - term pressure [5] - Short - fiber enterprises have high loads and low inventory, but downstream orders are weak. The absolute price fluctuates with raw materials [5] - Bottle chip production has decreased, and the processing margin has improved, but there is still long - term capacity pressure [5] Coal Chemical Industry - Methanol prices continued to decline. Although there is port de - stocking, demand has decreased, and the market is expected to be volatile and stalemate. There is support from reduced imports in the first quarter [6] - Urea production has increased, and downstream demand has also risen. The short - term market may decline slightly, but it is likely to be strong within a range as agricultural demand starts [6] Chlor - alkali - PVC prices weakened. Production capacity utilization has declined, and cost has increased. It is expected to reduce production capacity this year, and the price center may rise [7] - Caustic soda is in a weak state, with high inventory pressure. The industry is generally in a loss, and the profit of chlor - alkali integration is expected to be compressed [7] Soda Ash - Glass - Soda ash prices fluctuated widely. Inventory pressure is still high, supply pressure is large, and downstream demand is weak. A high - short strategy is recommended [8] - Glass prices declined due to ignition plans. The industry is de - stocking, but there may be an increase in supply. The order situation is poor, and there may be seasonal inventory accumulation [8]

1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - The cost side of PX, PTA, and MEG has more disturbances, and polyester prices fluctuate following the cost. The game between the downward feedback from downstream and the expected improvement remains the focus of market contradictions. For PX, beware of the real - world situation dragging it down; for PTA, it is expected to decline; for MEG, it is expected to fluctuate after a rebound [2][155]. 3.

Report's Core View - In the chemical industry, different products present diverse market conditions. Some products have positive short - term trends but face long - term supply - demand imbalances, while others are affected by factors such as weather, downstream demand, and production capacity changes [2][3][5]. Summary by Related Catalogs Olefins - Polyolefins - Propylene futures rose slightly. Supply is increasing, but lower prices led to better low - price sales. Polyolefins futures also rose slightly. Polyethylene has inventory pressure, and polypropylene's supply is still ample despite some improvement in the packaging sector [2]. Pure Benzene - Styrene - Pure benzene futures rebounded slightly. Its weekly production decreased, and port inventory declined, but high import expectations and poor downstream profits weakened the outlook. Styrene futures rose slightly but remained below the 5 - day moving average, with sufficient supply and weak demand [3]. Polyester - PX's strong supply - demand expectations weakened, but an oil price rebound drove up PX and PTA prices. PTA's profitability is poor. Ethylene glycol prices fell, with weak expectations. Short - fiber new capacity is limited, and demand is improving. Bottle - chip production was affected by typhoons, but long - term over - capacity is a concern [5]. Coal Chemical Industry - Methanol stopped falling. Port unloading was slow, and MTO plant operations increased, leading to port de - stocking. However, high port inventory limited price increases. Urea prices rose, but supply still exceeded demand, and the export window is closing [6]. Chlor - Alkali - PVC's supply - demand is loose, with high inventory. It may show a weak and volatile trend. Caustic soda has a weak current situation but strong future expectations, and the 2510 - 2601 spread may widen [7]. Soda Ash - Glass - Soda ash rose with glass. Soda ash production is expected to increase, and long - term supply is excessive. Glass prices rose due to industry meetings and planned price hikes. In the short - term, it may be strong, but long - term trends depend on capacity reduction [8].

1. Report Industry Investment Rating - No relevant content found. 2. Core Views of the Report PTA - Yesterday, PTA futures fluctuated and declined. The spot market negotiation atmosphere was average, and the spot basis was weak with differentiation. Polyester factories' bids increased. The mainstream spot basis today is at 01 - 51. The PTA device maintenance effect was less than expected, the spot market liquidity was okay, the spot basis weakened, and the price fluctuated following the cost side. Although the processing margin improved slightly from the low point, it remained at a relatively low level. Attention should be paid to the maintenance situation of Hengli Huizhou's device and subsequent upstream and downstream device changes [5]. - The spot price is 4700, the 01 - contract basis is - 32, and the futures price is at a premium, which is neutral. The PTA factory inventory is 3.81 days, a 0.1 - day increase compared to the previous period, which is bearish. The 20 - day moving average is downward, and the closing price is below the 20 - day moving average, which is bearish [6]. MEG - On Wednesday, the price of ethylene glycol (MEG) was consolidating at a low level, and the market negotiation was okay. The intraday MEG futures were weakly consolidating. The spot negotiation was traded at a premium of 86 - 92 yuan/ton to the 01 contract. Some contract merchants and suppliers participated in restocking, and the spot basis moderately strengthened at the end of the session. In terms of US dollars, the overseas MEG price was consolidating at a low level. The early - morning negotiation price for near - term shipments was around 524 - 525 US dollars/ton, and the afternoon negotiation price dropped to around 520 - 522 US dollars/ton. The 9 - end - of - September shipments were traded at around 519 - 523 US dollars/ton, and some financing merchants participated in inquiries [7]. - The spot price is 4434, the 01 - contract basis is 103, and the futures price is at a discount, which is bullish. The total inventory in East China is 40.63 tons, a 9.42 - ton decrease compared to the previous period, which is bullish. The 20 - day moving average is downward, and the closing price is below the 20 - day moving average, which is bearish. The arrival volume in early September is still moderately low, and there is still some room for a moderate decline in ports in the short term. In terms of demand, it is expected that the average load in September can reach 91.5%. The rigid demand support is gradually improving. Recently, the commodity market has corrected, and the MEG futures have been under pressure. It is expected that the price of MEG will mainly consolidate within a range in the short term, with strong support at the bottom. Subsequent attention should be paid to device changes and polyester load changes [7][8]. Influencing Factors - Bullish factors: In August, some PTA devices were scheduled for maintenance, improving supply - demand expectations. As the traditional "Golden September and Silver October" peak season approaches, the market has shown some expectations for demand recovery. Yisheng Hainan's 2 million - ton device stopped for maintenance, and Hengli Huizhou's 2.5 million - ton device had an unscheduled shutdown [11]. - Bearish factors: The profit margins of all links in the industrial chain continue to be under pressure, and the overall operating atmosphere remains cautious [10]. Current Main Logic and Risk Points - The short - term commodity market is greatly affected by the macro - level. Attention should be paid to the cost side. For the futures price rebound, attention should be paid to the upper resistance level [10]. 3. Summary by Relevant Catalogs 1. Previous Day's Review - No relevant content found. 2.

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.
