复产补库支撑，双焦震荡上行

Report Industry Investment Ratings - Glass: Oscillatory [2] - Soda Ash: Oscillatory with a Weakening Tendency [2] - Silicomanganese: Oscillatory [4] - Ferrosilicon: Oscillatory [4] Core Views - The resumption of production and restocking support the upward oscillation of coking coal and coke; the speculative demand for glass and soda ash increases, leading to oscillatory movements [1] - Market sentiment for ferrosilicon and silicomanganese has improved, with alloy prices rising slightly [3] Market Analysis Glass and Soda Ash - Glass: The main contract oscillated yesterday, with the spot price slightly adjusted by some manufacturers. The supply - demand contradiction has eased due to production line cold - repairs and increased consumer and speculative demand. The progress of cold - repairs and the sustainability of speculative demand should be monitored [1] - Soda Ash: The main contract oscillated and ended up rising. Short - term inventory reduction eases supply pressure, but long - term supply pressure remains due to increasing production capacity and limited demand from cold - repaired float glass production lines. Speculative demand provides short - term price support [1] Silicomanganese and Ferrosilicon - Silicomanganese: Geopolitical instability and coal news have boosted market sentiment, driving up alloy futures prices. The fundamentals have improved, but inventory pressure is still high. Demand is expected to improve with steel mill复产 and winter storage. Manganese ore prices support the silicomanganese price [3] - Ferrosilicon: Market sentiment has improved, and the futures perform well. The spot market is stable with strong cautious sentiment. Fundamentals are controllable, but inventory has increased due to slowed downstream procurement. Demand is expected to improve with steel mill复产 and winter storage. The impact of differential electricity price policies is limited [3] Strategy - Glass: Oscillatory [2] - Soda Ash: Oscillatory with a weakening tendency [2] - Silicomanganese: Oscillatory [4] - Ferrosilicon: Oscillatory [4] - Inter - period: None [2] - Inter - variety: None [2]
