Report Investment Rating - Glass: Oscillating with an upward bias [2] - Soda Ash: Oscillating with an upward bias [2] - Silicomanganese: Oscillating with an upward bias [4] - Ferrosilicon: Oscillating with an upward bias [4] Core Viewpoints - The raw material cost has pushed up steel prices strongly, and the prices of glass, soda ash, and double silicon have shown an upward trend [1][3] - The supply - demand contradictions of glass and soda ash are different, and attention should be paid to production line changes and new project progress [1] - The fundamentals of silicomanganese and ferrosilicon have different characteristics, and factors such as cost and demand need to be concerned [3] Market Analysis Glass and Soda Ash - Glass: The glass futures and spot prices rose significantly. Although some production lines have been cold - repaired, the production reduction is insufficient compared to the decline in rigid demand. The purchase of futures - spot traders may relieve inventory pressure, and the market expects a peak season after the Spring Festival [1] - Soda Ash: The futures and spot prices of soda ash rose. The rigid demand from downstream is limited, but the enthusiasm of futures - spot traders and traders has increased. The supply has decreased, and the inventory has increased month - on - month. Attention should be paid to the changes in float glass production lines and new soda ash projects [1] Double Silicon - Silicomanganese: Affected by the overall rise of the black series, the silicomanganese futures rose. The South African government plans to impose tariffs on unprocessed manganese ore, which may increase the cost. The current fundamentals are not good, with high production and large inventory growth. After the New Year's Day, the resumption of steel mills may repair the rigid demand, and the low port inventory of manganese ore provides support [3] - Ferrosilicon: The ferrosilicon market is running strongly. Traders are active in purchasing during the January steel tenders, and the sales are good. The fundamentals' contradictions have been significantly alleviated, the factory inventory has decreased, and the rigid demand is expected to improve after the resumption of steel mills. The implementation of differential electricity prices in Shaanxi may increase the cost [3] Strategy - Glass: Oscillating with an upward bias [2] - Soda Ash: Oscillating with an upward bias [2] - Silicomanganese: Oscillating with an upward bias [4] - Ferrosilicon: Oscillating with an upward bias [4] - Inter - period: None [2] - Inter - variety: None [2]
