Report Summary 1. Investment Rating No investment rating for the industry is provided in the report. 2. Core Views - The pessimistic sentiment in the black commodities market is receding, leading to a bottom - up rebound. The glass and soda ash markets show a divergence between futures and spot prices due to cautious downstream procurement. The double - silicon market has a stabilized sentiment with alloy prices oscillating [1][3]. - Glass has a severe supply - demand contradiction with high inventory and lack of substantial production cuts. Soda ash faces continuous supply - demand surplus pressure and strong de - stocking pressure [1]. - For silicon manganese, low production due to profit issues and high inventory suppress prices, while manganese ore cost provides support. Silicon iron production is at a low level, but demand has some resilience, and short - term prices are affected by costs [3]. 3. Summary by Related Catalogs Glass and Soda Ash - **Market Analysis** - Glass: Futures rebounded significantly yesterday, but spot trading was weak with mainly rigid demand procurement and low speculative sentiment. Soda ash: Futures rose sharply following black commodities, while downstream procurement was cautious with mainly rigid demand replenishment [1]. - **Supply - Demand and Logic** - Glass: The supply - demand contradiction is severe, high inventory suppresses prices, and there is no substantial production cut. Long - term losses are needed to clear excess capacity, and later changes in production lines and raw material prices should be monitored. Soda ash: With new production projects coming online, the supply - demand surplus persists, and there is strong de - stocking pressure. Prices will be under pressure until the surplus situation eases, and attention should be paid to intermittent production line maintenance and new production [1]. - **Strategy** - Glass: Oscillating. Soda ash: Oscillating. No cross - period or cross - variety strategies are recommended [2]. Double - Silicon (Silicon Manganese and Silicon Iron) - **Market Analysis** - Silicon Manganese: Futures oscillated and rebounded with black commodities yesterday. The spot market was stable, and factories were reluctant to sell at low prices. The price in the northern and southern markets was 5400 - 5500 yuan/ton. Silicon Iron: Futures oscillated. The cash - inclusive ex - factory price of 72 - grade silicon iron in the main production areas was 5150 - 5200 yuan/ton, and the price of 75 - grade silicon iron was 5750 - 5850 yuan/ton [3]. - **Supply - Demand and Logic** - Silicon Manganese: Production is at a low level due to industry profits, iron - water production has slightly declined but remains high, and demand has some resilience. High factory inventory and registered warehouse receipts suppress prices, while low - level manganese ore port inventory has slightly increased, and falling manganese ore prices support alloy costs. Attention should be paid to the manganese ore supply side. Silicon Iron: Production has dropped to the lowest level in recent years due to enterprise losses, high iron - water maintains demand resilience, factory inventory de - stocking is weakening, downstream inventory is low, and short - term prices are affected by costs. Attention should be paid to electricity price changes and industrial policies [3]. - **Strategy** - Silicon Manganese: Oscillating. Silicon Iron: Oscillating [4].

1. Market Analysis Glass and Soda Ash - Glass futures rebounded from a low level and showed a strong performance throughout the day, while the spot market was generally sluggish with some price cuts and slower shipments. The downstream mainly made rigid - demand purchases at low prices, and there was no large - scale speculative restocking. Due to poor real - estate completion data, the market is pessimistic about glass consumption. With low production, weak consumption, high inventory, and short - term restocking unable to change the weak situation, attention should be paid to glass production line changes and real - estate data [1]. - Soda ash futures showed a weak and volatile trend with lower trading sentiment. The domestic soda ash price was weakly stable with flexible transaction prices. Enterprise production increased, especially for heavy soda ash, and inventory slightly decreased, but downstream demand was mainly rigid. With new production projects coming on stream, high supply pressure has reappeared, and attention should be paid to intermittent maintenance and new production of soda ash production lines [1]. Silicomanganese and Ferrosilicon - For silicomanganese, tariff fluctuations and poor off - season consumption expectations led to a collective decline in the black sector, with a 0.87% drop in silicomanganese futures. The spot market was weak, with prices in the north and south at 5550 - 5650 yuan/ton. Affected by industry profits, production is at a low level, although it has slightly rebounded week - on - week. With high pig iron production currently providing demand support but a strong expectation of a peak in pig iron production, high inventories of manufacturers and registered warrants are suppressing prices. Low - level and slightly rising manganese ore port inventory, along with falling manganese ore prices dragging down shipments, support alloy costs, and attention should be paid to the manganese ore supply side [3]. - Ferrosilicon futures followed the black sector and slightly declined. The spot market was weak with cautious operations. The ex - factory price of 72 - grade ferrosilicon in the main production areas was 5300 - 5400 yuan/ton, and 75 - grade was 5900 - 5950 yuan/ton. With enterprises in losses, production has dropped to a near - historical low. High pig iron production maintains demand, but inventory reduction is weakening, downstream inventory is low, and production capacity is relatively abundant. Short - term prices are dragged down by costs, and attention should be paid to electricity price changes and industrial policies affecting the black sector [4]. 2. Strategy - Glass is expected to be in a volatile state, while soda ash is expected to be volatile and weak. There are no strategies for inter - delivery or inter - commodity trading [2]. - Both silicomanganese and ferrosilicon are expected to be in a volatile state [4].
