Report Investment Ratings - Glass: Neutral, Expected to Oscillate [2] - Soda Ash: Bearish, Expected to Oscillate with a Downward Bias [2] - Ferrosilicon Manganese: Neutral, Expected to Oscillate [5] - Ferrosilicon: Neutral, Expected to Oscillate [5] Core Views - Glass and soda ash markets face an oversupply situation, resulting in low - level oscillations. The glass market is pressured by high inventory and weak downstream expectations, while soda ash is affected by new production capacity and cautious downstream procurement [1]. - The ferrosilicon manganese and ferrosilicon markets are pessimistic. Their prices are suppressed by high inventory, but demand shows some resilience due to high - level hot metal production. Cost factors also play a role in price trends [3][4]. Market Analysis Glass and Soda Ash - Glass: Futures prices continued to decline, and spot trading was weak. The oversupply pattern remains unchanged, and high inventory strongly suppresses prices. Glass enterprises are reluctant to shut down production, and long - term losses are needed to clear excess capacity. Attention should be paid to production line changes and raw material prices [1]. - Soda Ash: Futures prices trended downward. Due to maintenance, daily production decreased slightly. Downstream procurement was cautious, and the market faced strong destocking pressure. The price will be under pressure until the oversupply situation is alleviated. Follow - up attention should be paid to production line maintenance and new production projects [1]. Ferrosilicon Manganese and Ferrosilicon - Ferrosilicon Manganese: Futures prices oscillated at a low level. The spot market was weak, and factory low - price sales willingness was low. Production was at a low level but rebounded slightly week - on - week. Demand showed resilience due to high - level hot metal production. High inventory of manufacturers and registered warrants suppressed prices, while raw material supply contraction supported costs. Attention should be paid to hot metal data and manganese ore supply [3]. - Ferrosilicon: Futures prices oscillated weakly at a low level. The spot market was weak, and downstream procurement was mainly for rigid demand. Production reached a record low due to enterprise losses. High - level hot metal maintained demand resilience, but destocking was difficult. Short - term prices were affected by costs. Attention should be paid to electricity price changes and industrial policies [4]. Strategy - Glass: Oscillate [2] - Soda Ash: Oscillate with a downward bias [2] - Ferrosilicon Manganese: Oscillate [5] - Ferrosilicon: Oscillate [5] - Inter - period Spread: No strategy [2] - Inter - commodity Spread: No strategy [2]
