Report Summary 1. Report Industry Investment Rating No specific industry investment rating is provided in the report. 2. Core Views - Glass and Soda Ash: Market sentiment is cautious, and both glass and soda ash are expected to oscillate. Glass needs long - term losses for capacity clearance, and soda ash prices are restricted by potential float glass cold - repairs [1][2]. - Silicon Manganese and Silicon Ferrosilicon: Both are expected to show an oscillatory trend. Silicon manganese prices will follow the sector's fluctuations, and silicon ferrosilicon prices will be weakly correlated with the sector in the short - term due to high inventory [3][4][5]. 3. Summary by Related Categories Glass and Soda Ash - Glass Market Analysis: Futures oscillated downward with reduced positions. Spot prices were stable regionally, and downstream demand was mainly for immediate needs. Supply contraction was insufficient, and high inventory persisted. Attention should be paid to cold - repairs and macro policies [1]. - Soda Ash Market Analysis: Futures oscillated with varying performance among contracts. Light soda ash consumption was better than heavy soda ash, and downstream demand was for immediate needs. Supply - demand contradictions were slightly alleviated, but inventory remained high. Heavy soda ash demand may face challenges due to potential float glass cold - repairs [1]. - Strategies: Glass and soda ash are expected to oscillate, with no specific cross - period or cross - variety strategies provided [2]. Silicon Manganese and Silicon Ferrosilicon - Silicon Manganese Market Analysis: Based on steel consumption data, building material consumption was fair. Futures rebounded strongly with the black market. Spot prices were firm, but production and operating rates continued to decline due to losses. Inventory reached a new high, and port manganese ore inventory increased slightly, providing cost support. Prices will follow the sector's fluctuations, and attention should be paid to basis, manganese ore cost, and production changes [3]. - Silicon Ferrosilicon Market Analysis: Futures rebounded with the black market. Spot prices were weakly stable with average trading volume. High production and inventory persisted, demand weakened marginally, and although inventory decreased slightly due to reduced operating rates, high inventory will continue to suppress prices. Attention should be paid to cost factors and regional policies [3][4]. - Strategies: Both silicon manganese and silicon ferrosilicon are expected to oscillate [5].
