1. Report Industry Investment Rating - The investment view of PVC is "oscillation", indicating that in the short - term, PVC has no obvious driving factors and is expected to mainly fluctuate [3]. 2. Core View of the Report - The macro - sentiment has subsided, and the PVC futures price is oscillating at the bottom. The supply of PVC remains high, demand is weak, cost support is insufficient, and the fundamentals are weak both in reality and expectation [6]. 3. Summary by Related Catalogs 3.1 Main Views and Strategy Overview - **Supply**: It has a bearish drive. The domestic PVC spot market has been slightly adjusted this week, with the supply - demand pattern remaining oversupplied. The PVC supply has slightly increased due to maintenance, and the market demand remains dull. The capacity utilization rate of PVC production enterprises is 78.26%, with the maintenance loss volume decreasing [3]. - **Demand**: It also has a bearish drive. Although downstream demand has slightly improved, the downstream operating rate is still at a low level.

Report Summary 1. Report Industry Investment Rating - Not provided in the content 2. Core View of the Report - The LLDPE market is in a volatile situation. The price of raw material crude oil has declined, and PE follows the cost change. The downstream agricultural film and packaging film industries have strong rigid - demand support, leading to inventory reduction. There is no strong short - term driving force for continuous decline. The supply - side has some new situations, and medium - term supply - demand pressure needs attention [2]. 3. Summary by Relevant Catalogs 3.1 Fundamental Tracking - **Futures Data**: The closing price of L2601 yesterday was 6899, with a daily decline of 0.99%. The trading volume was 342,532, and the position change was 15,690. The 01 - contract basis was - 79 (compared to - 98 the previous day), and the 01 - 05 contract spread was - 75 (compared to - 62 the previous day) [1]. - **Spot Price**: The spot prices in North China, East China, and South China were 6820 yuan/ton, 6960 yuan/ton, and 7110 yuan/ton respectively yesterday, showing a slight decline compared to the previous day [1]. 3.2 Spot News - This week, the domestic PE market price fluctuated narrowly. The upstream crude oil price dropped slightly, and there was no unexpected positive news from the Sino - US negotiation. The overall maintenance loss increased this week, and the domestic supply pressure was slightly relieved. On the demand side, the demand for greenhouse films and mulch films showed signs of peaking and falling, and the overall transaction volume was limited [1]. 3.3 Market Condition Analysis - The raw material price decline causes PE to follow the cost change. The downstream rigid demand supports inventory reduction. The short - term continuous decline is not strongly driven, and the market is in a volatile state. The supply - side has some new device situations, and the short - term contradiction is not significant. In the medium - term, attention should be paid to the supply - demand pressure caused by high - capacity and weakening demand [2]. 3.4 Trend Intensity - The LLDPE trend intensity is 0, indicating a neutral trend [2].

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].
