Report Industry Investment Rating - No information provided Core View of the Report - Due to the unchanged overall supply - demand pattern, plastics are expected to show a weak and volatile trend in the near term [1] Summary According to Relevant Catalogs Market Analysis - On November 18, the restart of maintenance devices such as Sinochem Quanzhou's HDPE led to the plastics operating rate rising to around 88%, which is at a neutral level. As of the week ending November 14, the PE downstream operating rate decreased by 0.36 percentage points to 44.49% week - on - week. The overall PE downstream operating rate is still at a relatively low level in the same period in recent years. Petrochemicals are de - stocking normally, and the current petrochemical inventory is at a neutral level in the same period in recent years. The crude oil price has limited increase due to the expected end of the US government shutdown and the adjustment of the global oil supply from shortage to surplus by OPEC. New production capacities have been put into operation, and the plastics operating rate has slightly increased. Although the agricultural film is in the peak season, its performance is not as expected, the downstream operating rate has declined, and the purchasing willingness of downstream enterprises is insufficient. Traders are cautious about the future market and are actively selling at reduced prices. There is no actual anti - involution policy in the plastics industry, which will affect the subsequent market [1] Futures and Spot Market Conditions - Futures: The plastics 2601 contract decreased by 0.95% with increased positions, closing at 6785 yuan/ton, below the 60 - day moving average. The trading volume increased by 6049 lots to 548344 lots [2] - Spot: Most PE spot markets declined, with price changes ranging from - 50 to + 0 yuan/ton.

The overall PE downstream operating rate is still at a relatively low level in the same period in recent years [4] - Inventory: On Tuesday, the petrochemical early - morning inventory decreased by 10,000 tons to 710,000 tons week - on - week, 25,000 tons higher than the same period last year.

Report Industry Investment Rating - Not provided Core View of the Report - The PVC market is experiencing a weak and volatile trend. Factors such as the decrease in PVC and downstream开工率, high inventory, upcoming implementation of anti - dumping duties in India, and the downturn in the real estate market contribute to this situation [1]. Summary by Relevant Catalogs Market Analysis - The calcium carbide price in the northwest region has increased by 25 yuan/ton. The PVC开工率 has decreased by 2.24 percentage points to 78.51%, still at a relatively high level in recent years. The downstream开工率 has slightly declined. The termination of India's BIS policy on PVC eases concerns about exports, but the upcoming anti - dumping duties make traders cautious. The export orders increased last week. The social inventory decreased slightly but remains high. The real estate market is still in adjustment, and the improvement needs time. The comprehensive profit of chlor - alkali is positive, and new production capacities are in operation. With the end of maintenance of some enterprises, high futures warehouse receipts, and other factors, PVC is expected to be weak and volatile [1]. Futures and Spot Market - The PVC2601 contract decreased by 1.46% to 4520 yuan/ton, with an increase in open interest by 107,079 lots to 1,462,620 lots [2]. - On November 18, the mainstream price of calcium carbide - based PVC in East China dropped to 4485 yuan/ton. The V2601 contract closed at 4608 yuan/ton, with a basis of - 35 yuan/ton, strengthening by 21 yuan/ton, and the basis is at a moderately low level [3]. Fundamental Tracking - On the supply side, some devices such as Tianjin LG and Henan Lianchuang are under maintenance. The PVC开工率 decreased by 2.24 percentage points to 78.51%. New production capacities like Wanhua Chemical (500,000 tons/year), Tianjin Bohua (400,000 tons/year), Qingdao Gulf (200,000 tons/year), Gansu Yaowang (300,000 tons/year), and Jiaxing Jiahua (300,000 tons/year) are in production at different loads [4]. - On the demand side, from January to October 2025, real estate investment, new construction, and completion areas decreased significantly year - on - year. The national real estate development investment was 735.63 billion yuan, down 14.7% year - on - year. The sales area of commercial housing was 719.82 million square meters, down 6.8% year - on - year. As of November 16, the weekly transaction area of commercial housing in 30 large - and medium - sized cities increased by 19.73% week - on - week but was still at the lowest level in recent years [5]. - In terms of inventory, as of the week of November 13, the PVC social inventory decreased by 1.27% to 1.0283 million tons, 23.76% higher than the same period last year, and the inventory is still high [6].

Report Industry Investment Rating - No industry investment rating is provided in the report. Core Viewpoints of the Report - Last week, the shutdown and maintenance of plants at Hengli Petrochemical, Zhenhai Refining & Chemical, and Zhongsha Petrochemical had a limited impact on the number of days. Zhenhai Refining & Chemical's Line 3 restarted, and the PE production and capacity utilization rate increased month-on-month. The downstream agricultural film operating rate remained stable, the packaging film operating rate decreased slightly, and the overall operating rate of PE downstream decreased slightly. Production enterprise inventories accumulated significantly, social inventories decreased slightly, and total inventories accumulated. The cost of oil-based production decreased slightly, the cost of coal-based production increased slightly, and the losses of both oil-based and coal-based processes deepened. [2] - This week, Zhongying Petrochemical's plant will be shut down for maintenance, and the plants of Zhenhai Refining & Chemical, Zhongsha Petrochemical, and Shanghai Petrochemical are expected to restart. PE production and capacity utilization rate are expected to change little month-on-month. In November, there is less new planned maintenance capacity for PE, and at the same time, two new plants of Guangxi Petrochemical continue to increase production, resulting in high supply pressure. [2] - The demand for northern greenhouse films is gradually declining, while the demand for southern greenhouse films still provides some support. Orders and operating rates for agricultural films are expected to fluctuate slightly; orders for packaging films are marginally weakening, and demand follow-up is limited. [2] - In terms of cost, OPEC's production increase will continue until the end of the year, and the situation of stronger supply than demand for crude oil is expected to continue. However, geopolitical tensions between the US and Venezuela may intensify, and there are both positive and negative factors affecting international oil prices. In the short term, L2601 is expected to show a volatile trend, with the range expected to be around 6750 - 6950.

Report Summary 1. Report Industry Investment Rating No information provided on the industry investment rating. 2. Core View of the Report The report indicates that the PVC market has significant domestic supply - demand contradictions. With high inventory pressure likely to persist, short - term V2601 is expected to fluctuate weakly in the range of 4500 - 4630 yuan/ton. The decrease in raw material prices has led to a decline in production costs, but due to weak spot prices, losses in both calcium carbide and ethylene methods have deepened. As the temperature drops, downstream demand in infrastructure and real estate is expected to weaken seasonally, and overseas demand remains uncertain [2]. 3.
