Report Industry Investment Rating - Not provided in the report Core Viewpoints - The industrial silicon futures market has strengthened again recently due to potential supply-side disturbances. It is expected that the silicon price may remain at a high level in the short term, but there is a risk of a subsequent decline. The polysilicon price is also in a high-level consolidation, and the spot price increase faces pressure [1]. - The supply of industrial silicon is increasing steadily, while the demand is mixed. The polysilicon industry has a certain demand increment, but the organic silicon and silicon-aluminum alloy industries have different situations [1].

The organic silicon market has supply pressure, and silicon-aluminum alloy enterprises purchase on demand, with low inventory willingness [1]. - **Polysilicon Supply**: Polysilicon enterprises maintain a production reduction trend, but some may have new production capacity put into operation. It is expected that the output will increase slightly, with an estimated output of nearly 110,000 tons in July and about 130,000 tons in August [1]. - **Polysilicon Demand**: The trading volume in the polysilicon market has increased significantly, and the inventory has decreased significantly. However, the terminal demand pressure is large, and the component price increase faces resistance [1]. Investment Strategies - **Industrial Silicon**: Adopt interval operation, buy out-of-the-money put options, and consider participating in the 2511 and 2512 reverse arbitrage opportunities [1]. - **Polysilicon**: Before the implementation of supply-side reform policies, try to go long on dips with a light position [1]. Industry News - Hebei Kuntian New Energy Co., Ltd.'s silicon-carbon anode material production line (Phase I, 1,000 tons) has been officially put into operation and started small-scale supply to domestic and foreign leading customers.

1. Report Industry Investment Rating No relevant content provided. 2. Core Views of the Report Industrial Silicon - Supply - The low - electricity - price environment in Southwest China's wet season is ending, and the growth rate of furnace - starting in Xinjiang is also slower than expected. The overall supply pressure is expected to gradually ease [4]. - Demand - The demand from the organic silicon industry has slowed, while the demand from the recycled aluminum alloy remains stable. The demand from the polysilicon sector is expected to increase steadily in the next two months [4]. - Market Outlook - If the supply - side production rate enters a downward channel and the downstream polysilicon demand improves, the oversupply situation may ease, and the industry may reach a price bottom - reversal point [4]. Polysilicon - Supply - The production plan in September is expected to increase month - on - month, exacerbating the supply - side surplus pressure. The increasing number of daily warehouse receipts also exerts pressure on the futures market [10]. - Demand - The production rhythm of silicon wafers and battery cells continues to slow, and the demand for polysilicon is restricted by factors such as lagging terminal installation demand and inventory digestion pressure [10]. - Market Outlook - If major enterprises in the industry reach effective integration agreements, it will fundamentally improve the supply - demand pattern and form long - term support for the market. Currently, investors are advised to be cautious [10]. 3.
