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]

Group 1 - Recent recovery in glass spot transaction volume, with some domestic regions achieving daily sales rates exceeding 200%, leading to a balanced inventory situation [1] - The production cost for coal-based glass production lines is approximately 1050 RMB/ton, while those using petroleum coke are around 1100 RMB/ton, indicating limited downside potential for current futures prices [1] - The current inventory structure shows a decline in market transaction activity, with downstream sectors focusing on inventory digestion, resulting in low purchasing demand [1] Group 2 - As of now, there are 286 float glass production lines in the country, with 221 in operation and a daily melting capacity of 157,405 tons, reflecting an industry capacity utilization rate of 80.50% [2] - The supply of glass has significantly decreased compared to the same period last year, placing current market supply at a near five-year low, while total demand has also declined [2] - The current glass spot prices have fallen below the production costs of most production lines, indicating potential for futures price rebound, although sustainability of such rebound remains weak [2]

Group 1: Report Industry Investment Rating - There is no information about the report industry investment rating in the given content. Group 2: Report's Core View - For soda ash, supply pressure remains high despite a decline in the industry's operating rate due to some enterprises' maintenance plans, as new capacity from companies like Yuanxing Energy may be released at any time. Demand from the glass industry is weak, with float glass affected by the sluggish real - estate sector and the photovoltaic industry facing over - capacity issues. Other downstream industries have limited demand. It is recommended to short the soda ash main contract on rallies [2]. - For glass, some production lines are resuming production, and there are plans for more ignitions, increasing supply pressure. Demand is weak due to the poor real - estate situation and the traditional off - season. However, prices may have a technical rebound near the cost line of some low - cost production lines. It is recommended to go long on the glass main contract on dips [2].
