1. Report Industry Investment Rating - No relevant content provided 2. Core Viewpoints of the Report - For industrial silicon, the supply and demand sides are weak, with costs such as electricity prices and coal coke remaining stable. Prices are expected to consolidate and await new drivers. In November, the production of polysilicon is scheduled to decline, and the demand for industrial silicon will be less supported.

1. Report Industry Investment Rating There is no information provided regarding the report industry investment rating in the given content. 2. Core Views of the Report - **Carbonate Lithium**: The post - holiday restocking enthusiasm of downstream enterprises exceeded expectations, but considering the seasonal changes in terminal demand, the demand growth rate may decline in the fourth quarter. The short - term price increase lacks sustainability. It is recommended to take a bearish approach on rallies, and upstream and downstream enterprises should choose the right time for hedging. The support for the main contract is 68,000 - 70,000, and the resistance is 80,000 - 82,000 [4][5]. - **Industrial Silicon**: With the approaching dry season, power costs are rising, and there may be large - scale shutdowns in the southwest region. The supply remains high, while the demand is weak. The inventory is accumulating, and the price is under pressure. However, due to cost support, the price is expected to fluctuate within a range. The support for the main contract is 8,400 - 8,500, and the resistance is 9,400 - 9,500 [5][6]. - **Polysilicon**: High profits drive high production enthusiasm, and the output is expected to increase in October. But the terminal demand is weak, and downstream production cuts are progressing, leading to inventory accumulation. With the expected implementation of policies, the market may fluctuate, and it is recommended to look for opportunities to short on rebounds. The support for the main contract is 49,000 - 50,000, and the resistance is 54,000 - 55,000 [8]. 3. Summary by Directory 3.1 First Part: Spot Prices 3.1.1 Plate Strategy Recommendation - **Carbonate Lithium 11**: The market is characterized by strong supply and demand but a weakening atmosphere.

Report Summary 1. Industry Investment Rating No industry investment rating is provided in the report. 2. Core Viewpoints - This week, industrial silicon prices rose by 1.66%, while polysilicon prices fell by 3.71%. The industrial silicon futures market showed an upward trend due to increased expectations of production cuts during the dry season, while polysilicon prices declined as the market sentiment subsided [4]. - Looking ahead, in the industrial silicon market, supply will see a combination of production cuts in the southwest and increased production in the northwest next week. Demand from polysilicon is highly uncertain, while that from organosilicon and aluminum alloy remains relatively stable. Cost provides support for prices, but high inventory restricts upward price movement. In the polysilicon market, supply will face rising production costs as the dry season approaches in the southwest, and demand remains weak overall, although emerging markets offer some buffer. Policy rumors have boosted market confidence, but the details and implementation time are unclear [4]. - It is recommended that the main contract of industrial silicon oscillates within the range of 8400 - 8600 yuan, with a stop - loss range of 8200 - 8800 yuan. The main contract of polysilicon will oscillate in the short term, within the range of 48000 - 53000 yuan, with a stop - loss range of 46000 - 55000 yuan [4]. 3. Summary by Directory 3.1 Weekly Highlights - **Market Review**: Industrial silicon prices increased by 1.66% this week, and polysilicon prices decreased by 3.71%. The industrial silicon futures market trended upward due to dry - season production cut expectations, while polysilicon prices declined as market sentiment faded [4]. - **Market Outlook**: - **Industrial Silicon**: Supply will see production cuts in Sichuan and Yunnan during the dry - season transition, while Xinjiang will increase production. Demand from organosilicon has some support, but polysilicon demand may weaken, and aluminum alloy demand is stable but has limited price - pulling power [4]. - **Polysilicon**: Supply will face rising costs in the southwest during the dry season, and demand is weak in the photovoltaic industry. Although emerging markets offer some support, European high inventory and uncertain policies add to market uncertainty [4]. - **Operation Suggestions**: The main contract of industrial silicon should be traded within the range of 8400 - 8600 yuan, with a stop - loss range of 8200 - 8800 yuan. The main contract of polysilicon should be traded within the range of 48000 - 53000 yuan, with a stop - loss range of 46000 - 55000 yuan [4]. 3.2 Futures and Spot Market - **Industrial Silicon**: The futures price increased this week, while the spot price remained flat, and the basis decreased.

1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - Industrial silicon supply shows a pattern of "increasing in the north and decreasing in the south". The supply pressure remains as the weekly production slightly increases. The demand support may weaken, and the cost provides some downside support.
