1. Report Industry Investment Ratings - Glass: Oscillating [2] - Soda Ash: Oscillating weakly [2] - Ferrosilicon Manganese: Oscillating [4] - Ferrosilicon: Oscillating [4] 2. Core Views - The glass and soda ash markets are oscillating weakly with inventory accumulation and weak spot sales. The double - silicon market has insufficient supply - demand contradictions and is oscillating [1][3]. 3. Summary by Related Catalogs Glass - Market Analysis: Yesterday, the glass futures oscillated weakly, and the spot market price remained stable with mediocre sales. This week, the inventory of float glass manufacturers was 53.064 million heavy cases, a 0.95% increase from the previous week [1]. - Supply - Demand and Logic: There are disturbances on the supply side, and production is expected to decrease. Rising coal prices have pushed up costs, and the inventory pressure on glass factories is not high, leading to a price rebound. However, the supply - demand is still loose, and the industry faces pressure without significant demand improvement. Attention should be paid to cold repairs of production lines and industrial policies [1]. - Strategy: Oscillating [2] Soda Ash - Market Analysis: Yesterday, the soda ash futures oscillated weakly, and the market was cautious. Downstream enterprises mainly made rigid - demand purchases. This week, the soda ash inventory was 1.5811 million tons, a 1.33% increase from the previous week [1]. - Supply - Demand and Logic: The supply - demand contradiction is relatively limited. After some alkali plants completed maintenance, supply increased. Considering new projects and the expected increase in cold repairs of float glass, the production profit of soda ash enterprises needs to be suppressed. Attention should be paid to changes in float glass production lines and new soda ash projects [1]. - Strategy: Oscillating weakly [2] Ferrosilicon Manganese - Market Analysis: Yesterday, the ferrosilicon manganese futures oscillated. The spot market sentiment fluctuated with the futures, with strong wait - and - see sentiment. The price in the northern market was 5,590 - 5,700 yuan/ton, and in the southern market, it was 5,720 - 5,770 yuan/ton [3]. - Supply - Demand and Logic: The fundamentals have improved, and there is an expected increase in hot metal production, leading to marginal improvement in demand. However, the inventory pressure is still large, and the supply - demand pattern is loose. The South African tariff policy may increase manganese ore costs, and attention should be paid to cost support and inventory changes [3]. - Strategy: Oscillating [4] Ferrosilicon - Market Analysis: Yesterday, the ferrosilicon futures oscillated. The spot price was stable, and the trading atmosphere improved slightly, mainly for rigid demand. The price of 72 - grade ferrosilicon in the main production area was 5,250 - 5,350 yuan/ton, and that of 75 - grade was 5,850 - 6,000 yuan/ton [3]. - Supply - Demand and Logic: The supply - demand contradiction is controllable. Enterprises have actively reduced production loads. With the resumption of steel mills, demand is expected to improve marginally. However, the overall over - capacity suppresses the price increase. Attention should be paid to inventory reduction and power price policies in production areas [3]. - Strategy: Oscillating [4]
