Report Industry Investment Rating No information provided. Core Viewpoints of the Report - The overall atmosphere in the commodity market was good yesterday, but the prices of finished steel products showed a weak and volatile trend. The demand for steel has officially entered the off - season, and there are still inventory risks for hot - rolled coils. Future attention should be paid to the pace of production cuts. With the implementation of the Fed's easing expectations and positive signals from the China - US meeting, the market sentiment and capital environment are expected to improve, and the consumption side of steel may gradually recover. In the short term, demand is still weak, but there may be an inflection point in the future [2]. - For iron ore, due to environmental protection restrictions and the decline in steel mill profits, the demand side continues to weaken, and the inventory pressure remains high. After the macro - events are realized, the fundamentals of iron ore are weak, and the price is expected to run weakly in the short term [5]. - Regarding manganese silicon and silicon iron, the fundamentals of manganese silicon are not ideal, and potential drivers may come from the manganese ore end. Silicon iron's supply - demand fundamentals have no obvious contradictions, and both are likely to follow the black - sector market [10]. - For industrial silicon, the supply - side pressure persists, and the demand support is weakening. It is expected to fluctuate in the short term. For polysilicon, the supply - demand pattern may improve marginally, but the short - term de - stocking range is limited [13][16]. - In the glass market, the short - term market may continue to fluctuate narrowly, and future attention should be paid to downstream orders and capacity changes. For soda ash, the price is expected to continue the weak and volatile pattern in the short term [19][21].

Report Industry Investment Rating No relevant information provided. Core Viewpoints - The overall sentiment in the commodity market is weak, leading to a decline in the industrial silicon and polysilicon futures markets. For industrial silicon, the current low valuation may present an opportunity for price increases if relevant policies are introduced. For polysilicon, the market is affected by anti - involution policies and weak reality, with limited upside potential and expected to remain in a wide - range oscillation [3][7]. Summary by Related Content Industrial Silicon Market Analysis - On November 4, 2025, the industrial silicon futures price dropped. The main contract 2601 opened at 9,130 yuan/ton and closed at 8,885 yuan/ton, a change of - 210 yuan/ton (- 2.31%) from the previous settlement. The position of the 2511 main contract was 242,153 lots at the close, and the total number of warehouse receipts was 45,823 lots, a decrease of 338 lots from the previous day [1]. - The spot price of industrial silicon remained stable. In November, the supply is expected to increase as some maintenance devices resume production, while demand shows no significant change, resulting in an oversupply situation. Although the cost of industrial silicon has been oscillating slightly upward recently, it can only provide short - term support for the price of DMC and cannot drive a substantial price rebound [1][2]. - In October 2025, China's industrial silicon production was 452,200 tons, a month - on - month increase of 31,400 tons (7.5%) and a year - on - year decrease of 17,600 tons (4%). From January to October 2025, the cumulative production of industrial silicon was 3.4699 million tons, a year - on - year decrease of 16.6% [1]. Strategy - The intraday correction was mainly affected by the overall commodity sentiment. Production cuts started in the southwest at the end of October, and the supply - demand pattern may improve. The industrial silicon futures market is currently oscillating based on the overall commodity sentiment and policy news. If relevant policies on capacity exit are introduced, there may be room for price increases. Short - term interval trading is recommended, and long positions can be taken at low prices for contracts during the dry season [3]. Polysilicon Market Analysis - On November 4, 2025, the main contract 2601 of polysilicon futures declined, opening at 56,000 yuan/ton and closing at 53,715 yuan/ton, a 3.91% decrease from the previous trading day. The position of the main contract was 128,876 lots (143,844 lots the previous day), and the trading volume was 274,348 lots [4]. - The spot price of polysilicon weakened slightly. The inventory of polysilicon manufacturers and silicon wafers increased. The latest statistics show that the polysilicon inventory was 261,000 tons, a month - on - month increase of 1.16%, and the silicon wafer inventory was 18.93GW, a month - on - month increase of 2.49%. The weekly production of polysilicon was 28,200 tons, a month - on - month decrease of 4.41%, and the silicon wafer production was 14.24GW, a month - on - month decrease of 3.32%. In October, the polysilicon production was about 133,500 tons, an increase from September, exceeding market expectations. In November, production in the southwest region will be significantly reduced, and production is expected to decline [4][5]. Strategy - The supply - demand fundamentals of polysilicon are average, with significant inventory pressure. Both supply and demand may decrease starting in November. The futures market is affected by anti - involution policies and weak market reality. Policy implementation and the downward transmission of spot prices need to be continuously monitored. It is expected that relevant policies will be introduced this year. Without significant improvement in consumer demand, the upside potential of the futures market is limited, and it is expected to remain in a wide - range oscillation. Short - term interval trading is recommended, and the 12 - contract is expected to oscillate between 50,000 and 57,000 yuan/ton [7].

Report Industry Investment Ratings - No industry investment ratings are provided in the reports. Core Views Industrial Silicon - Industrial silicon spot prices are stable, and futures prices fluctuate and rise after opening low. In November, the industrial silicon market still faces inventory accumulation pressure. Although supply may decline slightly and demand may remain stable, the increase in supply in the spot market may lead to inventory accumulation and put pressure on spot prices. However, there is cost - side support. It is expected to fluctuate at a low level, mainly in the range of 8500 - 9500 yuan/ton. Consider buying on dips when the price drops to around 8500 yuan/ton [1]. Polysilicon - Polysilicon spot prices are stable, and futures prices fluctuate and decline. Currently, futures are at a premium to the spot average. In November, supply pressure decreases, but demand also drops. The overall supply - demand is weak, and there is still inventory accumulation pressure. It is expected to fluctuate in a high - level range. Futures can be bought on dips near the lower edge of the range; options can sell put options around 50000 to earn premiums; the equity side can buy photovoltaic ETFs, new energy ETFs, or related stocks [2]. Glass and Soda Ash - Soda ash prices are weakly volatile, with low demand and obvious excess. The market is under pressure. In the medium - term, downstream demand will maintain the previous rigid - demand pattern. The supply - demand pattern is still bearish, and short - selling opportunities on rebounds can be considered. For glass, the news of production line shutdown in Shahe has a short - term emotional impact on the market, but in the long - term, there will be production line restarts, which will put pressure on supply. The deep - processing orders are seasonally weak, and the low - e开工率 is low. In November, there is still some peak - season demand expectation. Pay attention to the demand performance after price cuts. In the long - term, the glass industry needs capacity clearance. Short - term long - buying opportunities on rebounds can be grasped [4]. Logs - Log futures fluctuate. The main benchmark delivery product spot prices are unchanged. Last week, inventory increased slightly, and demand decreased slightly. The supply of arriving ships is increasing. The market is under pressure, but the price difference between domestic and foreign markets provides some support. Log futures are expected to maintain a weak - volatile trend [5]. Natural Rubber - In the short - term, cost - side supports rubber prices due to rainfall affecting rubber tapping. In the long - term, there is an expectation of increased supply. Demand is weak at the beginning of the month, and the replacement demand for all - steel tires in the north will further weaken. Dark - colored rubber has shown an inventory accumulation inflection point, and rubber prices may decline further.
