1. Report Industry Investment Rating - Not provided in the document 2. Core Views of the Report - The PE market is in a supply - strong and demand - weak situation in the short term, and it is expected to maintain a low - level oscillation pattern. The supply pressure continues to increase, while the demand support is insufficient. In the medium - and short - term, a bearish view is taken, and in the long - term, the supply pressure of non - standard PE products may suppress LLDPE prices [1][6]. 3. Summary by Relevant Catalogs 3.1 Core Contradictions and Strategy Recommendations 3.1.1 Core Contradictions - Supply side: The pressure is continuously increasing. There are few subsequent device maintenance plans, and the start - up rate is expected to continue to rise. In the fourth quarter, new device startups are still concentrated, such as the upcoming startups of two sets of Guangxi Petrochemical's devices [1]. - Demand side: The support is insufficient. Although the agricultural film industry is in the traditional peak season, the overall start - up rate and order growth rate have slowed down. After mid - November, the growth space for demand will be limited, and other downstream industries of PE have insufficient new orders [1]. 3.1.2 Trading Strategy Recommendations - **Trend judgment**: Weak oscillation. The price range of L2601 is 6600 - 7000. The strategy is to short on rallies [10]. - **Basis, spread, and hedging arbitrage strategy recommendations**: No basis strategy; 1 - 5 reverse spread; short - term hedging arbitrage space is limited, and in the long - term, consider narrowing the L - P spread on the 05 contract [10]. 3.1.3 Industrial Customer Operation Recommendations - **Inventory management**: For enterprises with high finished - product inventory, they can short plastic futures to lock in profits and sell call options to reduce costs [11]. - **Procurement management**: For enterprises with low procurement inventory, they can buy plastic futures to lock in procurement costs and sell put options to reduce costs [11]. 3.2 This Week's Important Information and Next Week's Events to Watch 3.2.1 This Week's Important Information - **Positive information**: On Wednesday, affected by the news of gas restrictions on Iranian devices, the methanol futures market strengthened, and polyolefins briefly followed the upward trend [12]. 3.2.2 Next Week's Events to Watch - The start - up situation of two sets of Guangxi Petrochemical's devices [12]. 3.3 Disk Interpretation 3.3.1 Price - Volume and Capital Interpretation - **Unilateral trend and capital movement**: This week, the futures market oscillated downward. The open interest increased, and there were no obvious changes in the top five long and short positions on the order book. The net long positions of the top five profitable seats slightly increased [17]. - **Basis structure**: The spot situation in East China improved and prices stabilized, but the situations in North and South China were still weak. As of Friday, the basis in North China was - 32 yuan/ton (strengthened by 47 compared with last week), in East China was 138 yuan/ton (+107), and in South China was 248 yuan/ton (- 3) [20]. - **Spread structure**: The L1 - 5 spread shows a contango structure due to the relatively optimistic market expectation for the subsequent macro - situation and the limited start - up of LLDPE devices in the first half of next year [22]. 3.4 Valuation and Profit Analysis - With the continuous weakness of PE prices, the production profits of all production lines are compressed. Currently, the coal - based production line with the best profit is also in a loss state. Since PE devices are not very sensitive to profit conditions, short - term losses usually do not lead to unexpected shutdowns, so PE lacks strong cost - side support in a downward market [26]. 3.5 Supply - Demand and Inventory Deduction 3.5.1 Supply - Demand Balance Sheet Deduction - The supply - strong and demand - weak pattern of PE is difficult to change. On the supply side, although device maintenance has increased recently, the high inventory capacity and the upcoming start - up of multiple devices in the fourth quarter, as well as the expected increase in imports after October, will further increase the total supply of PE. On the demand side, although the production and sales of agricultural films are still good, the subsequent growth is limited, and the support from other downstream industries of PE will gradually weaken [31]. 3.5.2 Supply - Side and Its Deduction - The current PE start - up rate is 82.56% (+1.69%). Multiple devices such as Fushun Petrochemical and ExxonMobil restarted at the beginning of the month, and the device maintenance volume decreased. It is expected that the device maintenance volume will continue to decrease, and with the upcoming start - up of two sets of Guangxi Petrochemical's devices, the supply pressure of PE will remain high [38]. 3.5.3 Import - Export and Its Deduction - **Import**: The overseas market is in a loose pattern, and the continuous decline in PE prices has led to an influx of low - price goods into China. Therefore, PE imports are expected to increase in the fourth quarter [43]. - **Export**: Enterprises' enthusiasm for expanding export channels is high this year, and PE exports have increased even in the off - season, but the total volume is still small and has little impact on the PE supply - demand pattern [43]. 3.5.4 Demand - Side and Its Deduction - The current average start - up rate of PE downstream industries is 45.75% (- 0.52%). The agricultural film industry is still in the peak season, but the start - up rate and order growth rate have slowed down. As the year - end approaches, the growth space for demand is limited, and the willingness of downstream enterprises to stock up has weakened [48].

Report Industry Investment Rating - Not provided in the content Core Viewpoints - The current supply-demand pattern of PE is characterized by strong supply and weak demand, which is difficult to change. The supply pressure remains high due to high inventory capacity and the successive commissioning of multiple devices in the fourth quarter, while the demand support will gradually weaken at the end of the year [1][8][33]. - In the short - to medium - term, PE is expected to show a weak and volatile trend, and a bearish view is recommended. In the long - term, the supply pressure of LLDPE may ease next year, but the supply pressure of non - standard products may suppress its price [8]. - The macro environment has a significant impact on the PE market. The weakening of the macro atmosphere and the decline in crude oil prices have led to a general decline in chemical products, and attention should be paid to subsequent policy changes [1]. Summary by Directory Chapter 1: Core Contradictions and Strategy Recommendations 1.1 Core Contradictions - Supply - demand level: Supply pressure is high as the total output remains high despite a slight increase in recent maintenance volume, and new devices are to be commissioned. Demand support is weak as the incremental space for demand is limited at the end of the year, and downstream raw material inventory is high [1]. - Macro level: Crude oil prices have peaked and declined, and the result of the Sino - US trade negotiation is lower than market expectations, leading to a weakening of the macro atmosphere. The influence of macro emotions and cost fluctuations on the PE market has increased [1]. 1.2 Trading - type Strategy Recommendations - Trend judgment: Weak and volatile [10]. - Price range: L2601 is between 6800 - 7100 [10]. - Strategy suggestion: Short on rallies [10]. 1.3 Industrial Customer Operation Suggestions - Price range forecast for polyethylene: 6800 - 7200 [12]. - Hedging strategies: For inventory management, short plastic futures and sell call options; for procurement management, buy plastic futures and sell put options [12]. Chapter 2: This Week's Important Information and Next Week's Attention Events 2.1 This Week's Important Information - Bullish information: Not provided in the content. - Bearish information: The Sino - US meeting result is lower than market expectations, new devices are commissioned, and the restart of some devices increases supply [18]. 2.2 Next Week's Important Events to Follow - OPEC + meeting results on December crude oil production, the situation of the Russia - Ukraine conflict, and relevant policy suggestions after the Fourth Plenary Session [18]. Chapter 3: Disk Interpretation 3.1 Price - Volume and Capital Interpretation - Unilateral trend: The disk reached a peak on Tuesday and then declined this week [20]. - Capital movement: The open interest increased this week, with no significant changes in the top five long and short positions in the order book, a slight reduction in net short positions of the top five profitable seats, and a slight increase in net short positions of the main profitable seats [20]. - Basis structure: The spot price lacks support and follows the decline of the PE disk. As of Friday, the basis in North China was - 79 yuan/ton (weakened by 20 compared with last week), in East China was 31 yuan/ton (- 10), and in South China was 251 yuan/ton (+ 70) [22]. - Spread structure: The L1 - 5 spread shows a contango structure due to the relatively optimistic macro expectations and the limited commissioning of LLDPE devices in the first half of next year [24]. Chapter 4: Valuation and Profit Analysis 4.1 Industry Chain Upstream and Downstream Profit Tracking - The production profits of all production lines have been compressed, and the coal - based production line with the best profit is also in a loss state. PE devices are not sensitive to profit conditions, so there is a lack of strong cost support during the downward trend [28]. Chapter 5: Supply - Demand and Inventory Deduction 5.1 Supply - Demand Balance Sheet Deduction - The pattern of strong supply and weak demand of PE is difficult to change. Supply pressure is high due to high inventory capacity, new device commissioning, and expected increase in imports after October. Demand support will gradually weaken as the incremental space for demand is limited at the end of the year [33]. 5.2 Supply - side and Deduction - The current PE operating rate is 80.86% (- 0.59%). Although the maintenance loss has increased, new device commissioning will still lead to high supply pressure [36]. 5.3 Import - Export and Deduction - Import: Overseas supply - demand is weak, and low - price goods are flowing into China, resulting in an increase in imports in the fourth quarter [41]. - Export: Enterprises are more active in expanding export channels, but the overall export volume is small and has little impact on the supply - demand pattern [41]. 5.4 Demand - side and Deduction - The average downstream operating rate of PE is 45.75% (- 0.38%). The agricultural film is in the peak season with increasing operating rate and orders, while the packaging film has insufficient new orders and a declining operating rate [49].

1. Report Industry Investment Rating No relevant content provided. 2. Core Views of the Report - In the short - term, polyolefins continued their downward trend this week, mainly driven by macro - sentiment and upstream cost fluctuations, with limited fundamental drivers. The market should focus on whether Sino - US trade frictions will escalate and if new stimulus policies will be introduced during the 20th Fourth Plenary Session. It is recommended to wait and see for unilateral trading [7]. - In the long - term, due to the large number of new PE installations planned to be put into production in the fourth quarter, the supply is expected to increase further. Without new demand - boosting policies, the supply - demand pressure of PE is difficult to resolve, and the weak pattern is expected to continue [8]. 3. Summary by Relevant Catalogs 3.1 Core Contradictions and Strategy Recommendations 3.1.1 Core Contradictions - Supply - demand aspect: The PE supply - demand pattern has not changed much. In October, the device maintenance volume decreased compared to September, and supply returned to a high level. Overseas PE supply - demand is weak, and import is expected to increase from October to November, intensifying supply pressure. Although it is the traditional peak season, demand recovery is slow, downstream orders are insufficient, and enterprises' willingness to replenish inventory is low. PE inventory, especially LLDPE inventory, is at a high level, and the upstream and mid - stream face great shipment pressure [2]. - Macro aspect: The continuous shutdown of the US government and market concerns about credit risks have increased risk - aversion sentiment in the financial market, putting downward pressure on crude oil. Sino - US trade policies are still uncertain, and if trade frictions escalate, it may lead to further price drops in crude oil and chemical products. The 20th Fourth Plenary Session next week is worth attention, and new stimulus policies may boost market sentiment [2]. 3.1.2 Trading Strategy Recommendations - Near - term trading logic: The market should focus on Sino - US trade frictions and new stimulus policies during the 20th Fourth Plenary Session. It is recommended to wait and see for unilateral trading [7]. - Long - term trading expectation: The supply - demand pressure of PE is difficult to resolve, and the weak pattern is expected to continue [8]. 3.1.3 Industrial Customer Operation Recommendations - Price range forecast for polyethylene: 6800 - 7200, with a current volatility of 8.43% and a historical percentile of 5.8% (3 - year) [13]. - Hedging strategy for inventory management: For enterprises with high finished - product inventory, they can short plastic futures to lock in profits and sell call options to reduce costs [13]. - Hedging strategy for procurement management: For enterprises with low procurement inventory, they can buy plastic futures to lock in procurement costs and sell put options to reduce costs [13]. 3.2 This Week's Important Information and Next Week's Attention Events 3.2.1 This Week's Important Information - Bullish information: The market's concern about the US imposing a 100% tariff on China was alleviated by Trump's signal. A 500,000 - ton LLDPE full - density device of Yulong stopped for 5 days due to a fault [15]. - Bearish information: The risk - aversion sentiment in the financial market led to a continuous decline in crude oil prices [16]. 3.2.2 Next Week's Important Events to Follow - The decline of the plastic market slowed down on Wednesday and Thursday, and the downstream's willingness to buy at the bottom increased, leading to a rapid increase in trading volume [17]. 3.3 Disk Interpretation 3.3.1 Price, Volume, and Fund Interpretation - Unilateral trend and fund movement: In the context of the continuous decline of crude oil, PE prices followed the downward trend. This week, the position increased slightly, and the market's bearish sentiment was strong [22]. - Basis structure: During the decline this week, the spot price weakened following the disk, and the basis strengthened passively [24]. - Spread structure: The spread structure has not changed much recently, and the L1 - 5 spread shows a contango structure [26]. 3.4 Valuation and Profit Analysis - As PE prices continued to be weak, the production profits of all production lines were compressed. The coal - based production line with the best profit is on the verge of losses. PE devices are not sensitive to profit, so short - term losses do not usually cause unexpected shutdowns, resulting in a lack of strong cost support during the price decline [28]. 3.5 Supply - Demand and Inventory Deduction 3.5.1 Supply - Demand Balance Sheet Deduction - With the restart of devices and the commissioning of new production capacity, supply pressure will gradually emerge. After October, imports are expected to increase, further increasing the total PE supply. Although it is the traditional peak season for PE downstream, demand growth is expected to be lower than supply. In October, inventory is expected to change from destocking to stocking rapidly, and the supply - strong and demand - weak pattern will suppress PE prices [34]. 3.5.2 Supply - Side and Deduction - The current PE operating rate is 81.76% (- 2.19%). This week, the device maintenance volume increased slightly. ExxonMobil's 500,000 - ton LDPE device is in the trial - run stage. Overall, the return of maintenance devices and the commissioning of new production capacity in the fourth quarter will lead to continuous high supply pressure [38]. 3.5.3 Import - Export and Deduction - Import: The overseas PE supply - demand pattern is loose, and the price difference between the US and China has dropped to a historical low. It is expected that PE imports will increase from late October to November [41]. - Export: Enterprises' enthusiasm for expanding export channels is high this year, and PE exports have increased even in the off - season, but the overall volume is still small and has little impact on the PE supply - demand pattern [41]. 3.5.4 Demand - Side and Deduction - The average operating rate of PE downstream industries is 42.17% (+ 0.56%). The agricultural film operating rate increased significantly, but the growth is slower than in previous years. Other downstream demand is flat, so the demand - side support for PE is limited [44].
