1. Report Industry Investment Rating - No relevant content provided 2. Core Viewpoints of the Report - Today, affected by macro - factors, chemical products generally declined. PE has a contradiction between weak reality and strong expectation, with its spot performance being weak recently but fundamentals expected to be better. If the current demand growth rate is maintained, the PE supply - demand structure is expected to be in a tight - balance state. The month - spread has changed from back to contango, and pressure on L09 is expected to be relieved when the PE spot shows positive feedback [3] - There are both positive and negative factors for PE. Positive factors include some full - density device conversions and potential import reduction from Iran due to conflicts. Negative factors are the planned commissioning of multiple HDPE devices in the middle of the year and weak spot prices [4][5] 3. Summary by Relevant Catalogs 3.1 Price Prediction and Volatility - The monthly price range prediction for polyethylene is 7100 - 7400, with a current 20 - day rolling volatility of 12.32% and a historical percentile of 21.7% over 3 years [2] 3.2 Hedging Strategies 3.2.1 Inventory Management - When inventory is high and there are concerns about price drops, for inventory management, it is recommended to short L2509 plastic futures with a 25% hedging ratio at an entry range of 7250 - 7300 to prevent inventory depreciation.

Group 1: Report Information - Report Name: Iron Alloy Industry Risk Management Daily Report [1] - Date: July 15, 2025 [1] - Analysts: Zhou Fuhan (Z0020173), Chen Mintao (F03118345) [1] - Investment Consulting Business Qualification: CSRC License [2011] No. 1290 [1] Group 2: Price Forecast and Hedging Price Forecast - Silicon Iron Price Range (Monthly): 5300 - 6000, Current Volatility: 20.20%, Current Volatility Historical Percentile (3 years): 54.1% [2] - Silicon Manganese Price Range (Monthly): 5300 - 6000, Current Volatility: 13.67%, Current Volatility Historical Percentile (3 years): 18.9% [2] Hedging - Inventory Management: For high finished - product inventory, short SF2509 and SM2509 futures with a 15% hedging ratio, recommended entry range: SF 6200 - 6250, SM 6400 - 6500 [2] - Procurement Management: For low procurement inventory, buy SF2509 and SM2509 futures with a 25% hedging ratio, recommended entry range: SF 5100 - 5200, SM 5300 - 5400 [2] Group 3: Core Contradiction and Market Trend - Last week, driven by anti - involution sentiment, ferroalloys maintained a slow upward trend. With profit recovery, the operating rate increased, and production was above the seasonal level. Production slightly increased, but downstream demand didn't change significantly. Silicon iron showed a stockpiling trend, and the de - stocking speed of silicon manganese slowed down. Considering factors such as the reduction of manganese ore quotes in August, the resumption of Australian ore shipments, and the negative feedback expectation of the black market in the off - season, ferroalloys are expected to remain weak. After the market recovery, there is a high possibility of increased production due to profit repair, and supply pressure may gradually increase. Silicon iron is under pressure at 5600 - 5700, and silicon manganese at 5800 - 5900. However, the overall price center of the black sector has moved up, and coal prices are strengthening, so the downside space of ferroalloys is limited. Ferroalloys may maintain a volatile trend [3] Group 4: Bullish Factors Silicon Iron - Inner Mongolia production area profit: - 261.5 yuan/ton (+70); Ningxia production area profit: - 98 yuan/ton (+50). With profit repair, there is a possibility of increased production. The weekly operating rate of silicon iron producers is 31.2%, a week - on - week decrease of 0.75%, and the weekly output is 9.87 tons, a week - on - week decrease of 1.5% [3] Silicon Manganese - The government's strict control policy on high - energy - consuming industries may lead to industrial structure adjustment and upgrading in the silicon manganese industry. The profit in the northern region is - 57.9 yuan/ton (+100.58), and in the southern region is - 393.26 yuan/ton (+96.32). The enterprise inventory is 22.08 tons, a week - on - week decrease of 0.67%; the warehouse receipts are 42.52 tons, a week - on - week decrease of 4.1%; the total inventory is 64.6 tons, a week - on - week decrease of 2.96% [5] Group 5: Bearish Factors Silicon Iron - This week, the enterprise inventory is 7.02 tons, a week - on - week increase of 4.78%. The warehouse receipt inventory is higher than the historical level after re - registration following the June cancellation rule. The expected decline in hot metal production weakens the support for ferroalloys [6] Silicon Manganese - In the long term, the sluggish real estate market and the decline of the black sector make the market skeptical about the growth of steel terminal demand, resulting in relatively weak demand for silicon manganese. The weekly operating rate of silicon manganese producers is 40.55%, a week - on - week increase of 0.21%, and the weekly output is 18.23 tons, a week - on - week increase of 1.22% [7] Group 6: Daily Data Silicon Iron - On July 14, 2025, the basis in Ningxia is 66, the 01 - 05 spread is - 60, the 05 - 09 spread is 134, the 09 - 01 spread is - 74. The spot prices in different regions and the prices of related raw materials and warehouse receipts are also provided [8] Silicon Manganese - On July 14, 2025, the basis in Inner Mongolia is 168, the 01 - 05 spread is - 34, the 05 - 09 spread is 74, the 09 - 01 spread is - 40, the double - silicon spread is - 298. The spot prices in different regions, the prices of manganese ore and other raw materials, and warehouse receipts are also provided [9][10] Group 7: Seasonal Charts - The report provides seasonal charts of silicon iron market price, basis, futures spreads, and total inventory, as well as silicon manganese market price, basis, futures spreads, and inventory [11][12][13][14][15][16][17][19][20][21][22][23][24][25][26][27][28][29][30][31]

Report Summary 1. Report Industry Investment Rating No relevant information provided. 2. Core Views - **Industrial Silicon**: In the second half of the year, the industrial silicon industry is in a cycle of accelerating the elimination of backward production capacity and entering the de - stocking process. The supply pressure will be continuously released with the implementation of production plans in Southwest China during the wet season. The downstream demand support is expected to strengthen, but inventory remains at a historical high. Overall, the price will show a wide - range oscillation. It is recommended to pay attention to the opportunity of placing long orders for industrial silicon at low prices [4]. - **Polysilicon**: In the second half of the year, the polysilicon market is in a stage where fundamental logic and "anti - involution" logic alternate. Fundamentally, the expected reduction in electricity prices and increased profits may boost production capacity. However, demand growth is limited, and high inventory pressure persists. If effective industry integration or coordinated production reduction measures are implemented, it may reverse the current situation. It is recommended to focus on the positive spread opportunity between PS2509 - PS2511 [7]. 3.

Group 1: Report Industry Investment Rating - Not provided in the content Group 2: Core Views of the Report - The supply - demand structure of asphalt shows a weakening trend, with weekly production increasing by 28% year - on - year and demand growing by 10% year - on - year. The inventory structure shows factory inventory accumulation and social inventory depletion, and speculative demand is weakening. The basis in Shandong and East China has weakened due to increased operating rates, while the crack spread remains high. Currently, the supply increase exceeds expectations slightly, and the demand is still in the off - season due to rainfall. The overall fundamentals have weakened month - on - month. In the medium to long term, demand is expected to pick up as construction conditions improve in August, and the peak season is still worth looking forward to. Short - term attention should be paid to the cargo flow situation and the details and authenticity of the fuel oil consumption refund policy in Shandong [2] - There are both positive and negative factors for asphalt. Positive factors include low factory inventory pressure, seasonal peak demand, low operating rates and the expectation of catch - up construction in the South. Negative factors include the resumption of production in some refineries after maintenance, short - term demand drag from the plum rain season in the South, and weakening basis [3][6] Group 3: Summary by Relevant Catalogs 1.

Core Views of the Report Industrial Silicon - In the second half of the year, the industrial silicon industry will be in a cycle of accelerating the clearance of backward production capacity and entering the de - stocking process. The supply pressure will be released with the implementation of production plans in Southwest China during the wet season. The downstream demand is expected to strengthen, with the photovoltaic industry potentially boosting demand, while organic silicon and aluminum alloy enterprises maintaining stable demand. The price will show a wide - range fluctuation. Suggestions include looking for opportunities to go long on industrial silicon at low prices, SI2509 - SI2511 positive spread trading, and going long on industrial silicon while shorting polysilicon [4]. - Positive factors are the "anti - involution" policy, limited downward space for costs, and better - than - expected demand. Negative factors are the release of production capacity in Southwest China during the wet season and potential weakening of demand due to industrial integration in the polysilicon industry [5][6]. Polysilicon - In the second half of the year, the polysilicon market is in a stage where fundamental and "anti - involution" logics alternate. Fundamentally, lower electricity prices and higher profits may increase production capacity. However, demand growth is limited, and high inventory persists. If industry integration is effective, it may drive prices up. The suggestion is to focus on PS2508 - PS2511 positive spread trading [8]. - Positive factors are potential industry integration and increased external demand from the US. Negative factors are inventory accumulation if integration fails [9][10]. 3.

Core Views - **Industrial Silicon**: In the second half of the year, the industrial silicon industry is in a cycle of accelerating the clearance of backward production capacity and will enter the de - stocking process. The supply pressure will be released with the implementation of production plans in the southwest during the wet season, while the downstream demand is expected to strengthen. The price will show a wide - range oscillation. Strategies include focusing on SI2509 - SI2511 positive spread opportunities and the chance of going long on near - month industrial silicon and shorting far - month polysilicon [4]. - **Polysilicon**: In the second half of the year, the polysilicon market is in a stage where fundamental logic and "anti - involution" logic alternate. Fundamentally, lower production costs may lead to increased production capacity, while demand growth is limited, and inventory pressure remains high. If industry integration is effective, it may drive up prices. The recommended strategy is to focus on PS2508 - PS2511 positive spread opportunities [8]. 3.
