1. Report Industry Investment Rating No information provided in the content. 2. Core Views of the Report Industrial Silicon - This week (2025.12.19 - 2025.12.26), the spot price of industrial silicon trended upward, with the benchmark spot price at 8800 yuan/ton on December 26, up 0.79% from December 19. The futures market's main contract fluctuated downward, but with a weekly increase of 2.19%. The current main - month contract's open interest is about 224,700 lots [9]. - Supply slightly increased as production in Yunnan and Sichuan decreased, while that in the Northwest increased, and Hunan stopped production entirely. However, due to weak downstream demand, this change had no significant market impact [9]. - Demand for industrial silicon decreased as the supply of polysilicon continued to shrink in December, the domestic silicone industry's production reduction advanced, and the output of aluminum rods slightly decreased. Exports in November 2025 were 54,900 tons, up 21.78% month - on - month and 3.72% year - on - year. From January to November, the total export was 661,500 tons, showing an increase compared to previous months [9]. - Costs were basically stable this week, and profits increased due to stable costs and rising market prices [9]. - Overall inventory trended upward [9]. - Looking ahead, with stable supply, weak downstream and terminal demand, and high inventory, the market is expected to decline further. Suggested strategies include shorting si2605 at high prices, with an expected operating range of 8000 - 9500 yuan/ton; buying put options; or using an arbitrage strategy of shorting industrial silicon and going long on polysilicon [9]. Polysilicon - This week (2025.12.19 - 2025.12.26), the spot price of polysilicon fluctuated within a range. The benchmark spot price on December 26 was 56,105 yuan/ton, up 0.21% from December 19. The futures market's main contract fluctuated upward, but with a weekly decrease of 2.14%. The current main - month contract's open interest is about 119,100 lots [11]. - Supply continued to shrink in December, with a small overall decline. Although some enterprises in the Southwest reduced production due to the dry season, there was an increase in the Northwest. The domestic polysilicon output in December is expected to be about 115,000 tons, and supply may continue to decline slightly next month [11]. - Overall demand contracted due to the off - season, and downstream procurement was sluggish due to production cuts and high inventory, making it difficult for industry demand to recover quickly. Short - term attention should be paid to inventory digestion and downstream production scheduling changes [11]. - Costs increased slightly this week, and profits decreased slightly [11]. - The current polysilicon industry inventory is high and difficult to reverse substantially. The overall reduction in supply was limited, and it did not fully match the decline in demand [11]. - Most polysilicon enterprises have raised new order quotes to 65,000 yuan/ton, reflecting their optimistic expectations and price - support intentions. The price difference between quotes and transactions is a game between cost support from production cuts and cautious procurement due to weak downstream demand. The establishment of the purchase and storage platform is seen as a potential positive factor, improving market sentiment and transaction atmosphere. Suggested strategies include going long on PS2605 at low prices, with an expected operating range of 55,000 - 70,000 yuan/ton; buying call options; or using an arbitrage strategy of shorting industrial silicon and going long on polysilicon [11]. 3.
