Report Summary 1. Report Industry Investment Rating No relevant information provided. 2. Core Viewpoints - Strategy suggestion: The short - term price of the br2601 contract is expected to fluctuate between 10,000 - 10,600 [7]. - Market review: This week, the price of cis - butadiene rubber in the Shandong market dropped sharply and then rebounded slightly, with the spot price ranging from 9,750 - 10,900 yuan/ton. Sinopec and most sales companies of PetroChina lowered the ex - factory price of high - cis cis - butadiene rubber by 800 yuan/ton in total. The price of raw material butadiene dropped more than expected due to the dual negative impacts of the expected increase in domestic supply and the continuous decline in foreign market negotiation prices, leading to a significant increase in market bearish sentiment [8]. - Market outlook: Most previously shut - down cis - butadiene rubber plants have restarted, and domestic production has recovered. Recently, the supply of raw material butadiene is sufficient and the negotiation price has been falling, continuously dragging down the cost side. Downstream buyers are bargaining, causing the negotiation price of private resources to drop significantly. Some production enterprises' inventory and sample trading enterprises' inventory have decreased. Next week, some plants will restart, and supply is expected to increase slightly. However, due to the expected increase in future domestic supply of the raw material, the cost side of cis - butadiene remains weak, and the situation of downstream terminal buyers firmly bargaining is difficult to change. The inventory of production enterprises and trading enterprises may increase slightly. In terms of demand, the production scheduling of domestic tire maintenance enterprises has returned to the normal level this week, driving a slight increase in overall capacity utilization. Most other enterprises' equipment is operating stably. Next week, most enterprises will maintain stable production to meet order demands. It is heard that an individual enterprise has a maintenance plan in the middle of the month, which may drag down the overall capacity utilization [8]. 3. Summary by Directory 3.1.

Report Summary 1) Report Industry Investment Rating No investment rating information is provided in the report. 2) Core Views - **Rapeseed Meal**: The rapeseed meal market is in a situation of weak supply and demand. Near - month imports of Canadian rapeseed and rapeseed meal are restricted, and oil mills' rapeseed stocks are depleted with widespread shutdowns, resulting in less supply pressure. However, the demand for rapeseed meal is weakening due to the decline in aquaculture demand as the temperature drops and the ample supply and good substitution advantage of soybean meal. Recently, influenced by trade optimism, the prices of rapeseed meal and soybean meal have rebounded from lows and strengthened in the short - term. Attention should be paid to whether there will be a breakthrough in China - Canada trade policies [2]. - **Rapeseed Oil**: The supply of imported rapeseed is structurally tightened in the near - month. Oil mills' rapeseed stocks are exhausted, and shutdowns are common, so rapeseed oil will continue to be in a de - stocking mode, which supports its price. But the supply of soybean oil is abundant and has a good substitution advantage, so the demand for rapeseed oil is mainly for rigid needs. After a continuous decline, the rapeseed oil futures price has recovered from the low recently, and short - term observation is recommended [2]. 3) Summary by Relevant Catalogs Futures Market - **Prices**: The futures closing price of rapeseed oil (active contract) was 9,564 yuan/ton, up 157 yuan; that of rapeseed meal was 2,549 yuan/ton, up 12 yuan.

From October 24th to 30th, the downstream PE operating rate decreased by 0.4% week-on-week, with the agricultural film operating rate up 2.4% and the packaging film operating rate down 1.3%.

L2601 rebounded after a decline, closing at 6,805 yuan/ton. In November, there will be less new maintenance capacity for PE, and two new units of Guangxi Petrochemical are about to be put into operation, resulting in high supply pressure. Affected by the restart of 400,000 tons of Lianyungang Petrochemical and 450,000 tons of Baolai units this week, PE production increased week-on-week. The downstream greenhouse film is in the peak season, and the operating rate of agricultural film is expected to remain high; the orders for packaging film are being delivered successively, and the operating rate is expected to gradually weaken. The inventory of producers and social inventory will continue to decline, and the inventory pressure is not significant. The accumulation of API and EIA inventories in the US, combined with the strengthening of the US dollar, has led to a recent weak and volatile international oil price. In the short term, L2601 is expected to fluctuate weakly in the range of 6,740 - 6,850 [2].

Group 1: Report Overview - The report is a PVC industry daily report dated November 6, 2025 [2] Group 2: Core Viewpoints - The PVC futures contract V2601 fell and then rebounded, closing at 4,630 yuan/ton.
