Report Industry Investment Rating - The rating for unilateral investment is neutral, suggesting short - term observation [2] Report's Core View - The asphalt fundamentals remain weak, and the market shows a weak oscillating trend. The weakening of rigid demand in northern provinces seasonally suppresses market sentiment, and there is insufficient upward drive in the market [1] Summary Based on Relevant Catalogs Market Analysis - On October 30, the closing price of the main asphalt futures contract BU2601 in the afternoon session was 3254 yuan/ton, down 13 yuan/ton or 0.4% from the previous settlement price. The open interest was 196,796 lots, up 770 lots from the previous day, and the trading volume was 160,811 lots, down 12,955 lots from the previous day [1] - The spot settlement prices of heavy - traffic asphalt from Zhuochuang Information are as follows: Northeast 3406 - 4750 yuan/ton; Shandong 3200 - 3620 yuan/ton; South China 3370 - 3580 yuan/ton; East China 3410 - 3500 yuan/ton. The spot price of asphalt in North China decreased, while that in South China increased slightly, and prices in other regions remained relatively stable [1] - After the successful conclusion of China - US trade negotiations, macro risks have weakened. However, due to the weakening fundamentals of crude oil prices, the cost - driving effect on asphalt is limited [1] Strategy - Unilateral: Neutral, with short - term observation as the main strategy - Cross - period: None - Cross - variety: None - Futures - spot: None - Options: None [2]

Report Summary 1) Report Industry Investment Rating - Unilateral: Cautiously bearish, mainly on short - term wait - and - see [2] - Inter - period: None [2] - Inter - variety: None [2] - Futures - spot: None [2] - Options: None [2] 2) Core View of the Report - The market has insufficient positive factors, and the market fluctuates at a low level. The asphalt futures and spot markets are affected by multiple factors, with a current pattern of weak supply and demand. The market lacks upward momentum, and it is necessary to wait for the implementation of major macro - events [1]. 3) Summary by Related Catalogs Market Analysis - On October 21, the closing price of the main BU2601 contract of asphalt futures in the afternoon session was 3,157 yuan/ton, up 13 yuan/ton or 0.41% from the previous settlement price. The open interest was 182,020 lots, a net increase of 14,315 lots, and the trading volume was 168,391 lots, a net increase of 8,384 lots [1]. - The spot settlement prices of heavy - traffic asphalt from Zhuochuang Information are as follows: 3,506 - 4,086 yuan/ton in the Northeast, 3,260 - 3,620 yuan/ton in Shandong, 3,340 - 3,550 yuan/ton in South China, and 3,410 - 3,500 yuan/ton in East China. The spot prices of asphalt in North China, Shandong, East China, and Sichuan - Chongqing continued to decline yesterday, slightly increased in South China, and remained relatively stable in other regions [1]. - Crude oil and asphalt futures maintained weak fluctuations, which was negative for the sentiment of the asphalt spot market. The current pattern of weak supply and demand in the asphalt market continues, but the sharp drop in oil prices boosts refinery profits, and the supply side has certain elasticity. At the same time, the overall rigid demand for asphalt is weak, the downstream purchasing sentiment is weak, and most market prices continue to decline. Currently, the market still lacks the impetus to rebound [1]. Figures - There are a series of figures in the report, including spot prices of heavy - traffic asphalt in different regions (Shandong, East China, South China, North China, Southwest, and Northwest), closing prices of asphalt futures indices, main contracts, and near - month contracts, trading volume and open interest of asphalt futures, weekly domestic asphalt production, asphalt production of independent refineries and in different regions (Shandong, East China, South China, North China), domestic asphalt consumption in different fields (road, waterproofing, coking, ship - fuel), and asphalt inventories in refineries and society [3].

1. Report Industry Investment Rating No relevant content provided. 2. Core Views of the Report - Mid - term: The report believes that it is highly likely for asphalt valuation to decline in the second half of the year. The current operation rate of independent refineries is at a low level, with limited room for further decline. The return of major refinery production capacity and the seasonal off - peak valuation period will restrict the upward space of asphalt valuation (asphalt/crude oil), and the weak shock of crude oil at the cost end will also limit the upward space of asphalt's single - side price [16]. - Short - term: The weakness of asphalt has been gradually realized, and the supply - demand contradiction is relatively small in the short term. It is recommended to wait and see [17]. 3. Summary by Directory 3.1 Monthly Evaluation and Strategy Recommendation - **Market Review**: The report presents the recent trend chart of the asphalt main contract, and analyzes the influence of supply - demand and cost factors on the price [13][14]. - **Mid - term Impact Factor Assessment**: - **Supply**: Import is expected to remain low. Major refineries are expected to resume a certain operating rate, which will restrict the upward movement of asphalt valuation. However, for the valuation to decline, local refineries need to significantly recover, and they are expected to remain relatively sluggish in the short - to - medium term [16]. - **Demand**: The demand - side operation rate has improved slightly compared with previous years, but the overall asphalt shipment volume is lower than expected. The infrastructure peak season has passed, and the overall demand is expected to be flat [16]. - **Cost**: The upward space of oil prices in the second half of the year is limited. With the gradual increase in production by OPEC, the wide - range shock center of oil prices is expected to move down slightly. Shale oil will play a bottom - supporting role, and it is difficult to have a continuous trend market [16]. - **Short - term Factor Assessment**: - **Supply**: The operating rate of heavy - traffic asphalt has started to decline, and imports are expected to remain low due to geopolitical factors in peripheral heavy - oil countries [17]. - **Demand**: The operation rates of all demand - side segments remain weak, and the weakness of waterproofing membranes exceeds expectations [17]. - **Inventory**: The overall inventory shows a phenomenon of weak destocking, and social inventory fails to meet the destocking expectation. The domestic total inventory accumulates more than expected [17]. - **Cost**: The crude oil cost is expected to stop falling and stabilize, as the current oil price has entered the break - even price of some shale oil production areas in the United States. The oil price is suppressed by political expectations but supported by fundamentals [17]. 3.2 Spot and Futures Market - **Spot Price**: The report shows the price trends of heavy - traffic asphalt in Shandong, Northeast, North China, and East China regions [20][23][24][26]. - **Basis Trend**: It presents the basis trends of asphalt in Shandong and East China regions [31]. - **Term Structure**: It shows the term structure of asphalt and the price differences between different contracts [34][35]. 3.3 Supply Side - **Capacity Utilization and Profit**: It shows the capacity utilization rate of heavy - traffic asphalt and the production profit of asphalt in Shandong [41]. - **Import**: It presents the import volume, import profit, and cumulative import volume from different countries of asphalt, as well as the import volume of diluted asphalt [48][50][55]. - **Valuation Ratio**: It shows the valuation ratios of fuel oil/asphalt and asphalt/Brent [59]. - **Refinery Profit**: It shows the refining profits of major refineries and Shandong local refineries, as well as the operation rate and production profit of petroleum coke [61][64][65]. 3.4 Inventory - **Domestic Inventory**: It shows the inventory trends of domestic factories, social inventory, total domestic inventory, and diluted asphalt port inventory [69]. - **Warehouse Receipts**: It shows the quantity of asphalt warehouse receipts and the virtual - to - real ratio of the asphalt main contract [73]. 3.5 Demand Side - **Enterprise Shipment Volume**: It shows the asphalt shipment volumes of Chinese, Shandong, East China, and North China sample enterprises [81]. - **Downstream Operation Rate**: It shows the operation rates of rubber shoe materials, road - modified asphalt, and waterproofing membranes [90]. - **Highway Investment**: It shows the cumulative value of highway construction investment in China's transportation fixed - asset investment, the monthly year - on - year and monthly value of public fiscal expenditure on transportation [97]. - **Road - related Machinery**: It shows the monthly sales volumes of road rollers and excavators, the monthly operating hours of excavators, and the cumulative value of highway construction investment in China's transportation fixed - asset investment [108]. - **Related Consumption**: It shows the completion amount of fixed - asset investment and the cumulative issuance amount of special local government bonds [114]. 3.6 Related Indicators - **Position, Trading Volume, and Price Volatility**: It shows the trading volume, position, and 20 - day historical volatility of asphalt futures [120]. 3.7 Industrial Chain Structure Diagram - **Crude Oil Industrial Chain**: It briefly describes the exploration and extraction links of the crude oil industrial chain [129]. - **Asphalt Industrial Chain**: It classifies asphalt from the perspectives of production process and usage, and points out its main applications [133].
