Downstream procurement is cautious, mainly for rigid demand. Supply is generally stable, consumption is affected by speculative demand and downstream inventory replenishment, inventory has decreased but overall change is limited, and fundamentals suppress prices. Attention should be paid to macro - policy changes and peak - season demand [1] Soda Ash - Yesterday, the soda ash futures market opened lower and oscillated weakly. Downstream procurement is mainly for rigid - demand replenishment. There are still supply - demand contradictions, and attention should be paid to whether speculative demand weakens. The futures premium suppresses prices, and attention should be paid to new - capacity投产 progress and inventory changes [1] Silicomanganese - Yesterday, the coking coal futures tumbled, and the silicomanganese futures followed suit. The main contract closed at 5,820 yuan/ton, down 46 yuan/ton from the previous day.节前 market transactions were sluggish. This week, production continued to decline, hot - metal production increased slightly, downstream demand remained resilient, and alloy - enterprise inventory increased significantly. In the long run, supply - demand is relatively loose. Considering the futures discount to the spot, prices are expected to oscillate and follow the sector's fluctuations. Attention should be paid to regional policies and cost - support changes [3] Ferrosilicon - Yesterday, the main ferrosilicon futures contract closed at 5,610 yuan/ton, down 70 yuan/ton from the previous day. The market sentiment was average, and the trading atmosphere needed to be strengthened. This week, production and operating rates rebounded slightly, demand increased slightly with hot - metal production, factory inventory decreased month - on - month, and inventory was at a medium level compared to the same period. Currently, there are few supply - demand contradictions, and prices are expected to follow the sector's fluctuations. Attention should be paid to changes in coal and electricity prices at the cost end and regional policies [3] Group 4: Figures - The report includes figures such as Shanghai rebar and hot - rolled coil spot price trends, futures contract closing - price trends, basis trends, cost and profit trends of various products, and spot price trends of raw materials like iron ore, coke, and coking coal [5]

Group 1: Report Industry Investment Ratings - No specific industry investment ratings are provided in the report. Group 2: Core Views - The expectation of interest rate cuts has been realized, and steel inventories continue to accumulate. The glass and soda ash markets show factory inventory destocking and significant downward movement in the futures market. The double - silicon market features firm spot prices and strong alloy performance [1][3]. Group 3: Market Analysis and Strategy for Glass and Soda Ash Glass - **Market Analysis**: Yesterday, glass futures fluctuated downward. Downstream procurement was cautious, mainly for immediate needs. With the recent price increase, glass production and sales improved month - on - month. This week, the operating rate of float glass enterprises was 76.01%, unchanged from the previous period, and factory inventory was 60.908 million heavy boxes, a 1.1% month - on - month decrease. There is still a supply - demand contradiction in the glass market, and the short - term premium in the futures market suppresses price increases [1]. - **Strategy**: The price trend is expected to be oscillating and weakening [2]. Soda Ash - **Market Analysis**: Yesterday, soda ash futures also fluctuated downward. Downstream demand was mainly for rigid restocking. This week, the operating rate was 85.53%, a 2.02% month - on - month decrease, production was 745,700 tons, a 2.02% month - on - month decrease, and inventory was 1.7556 million tons, a 2.33% month - on - month decrease. The supply - demand imbalance will continue with new production capacity coming online in the fourth quarter, and the current premium in the futures market further suppresses price increases [1]. - **Strategy**: The price trend is expected to be oscillating and weakening [2]. Group 4: Market Analysis and Strategy for Double - Silicon (Manganese Silicon and Ferrosilicon) Manganese Silicon - **Market Analysis**: Yesterday, manganese silicon showed an oscillating and strengthening trend. The manganese ore market maintained a price - supporting sentiment. The final price of the mainstream steel tender was 6,000 yuan/ton, with the price in the northern market at 5,680 - 5,730 yuan/ton and in the southern market at 5,700 - 5,750 yuan/ton. Production and sales slightly increased, but enterprise inventory rose due to continuous production growth. In the long term, the supply - demand pattern tends to be loose [3]. - **Strategy**: The price is expected to oscillate [4]. Ferrosilicon - **Market Analysis**: Yesterday, ferrosilicon futures continued to oscillate and strengthen. The market sentiment was average, with the price of 72 - grade ferrosilicon natural lumps in the main production areas at 5,300 - 5,400 yuan/ton and 75 - grade ferrosilicon at 6,000 - 6,050 yuan/ton.

The industry has an obvious supply surplus, and profits are constrained without industrial policies [3]. - **Strategy**: The price is expected to oscillate [4].

1. Report Industry Investment Ratings - Glass: Oscillating weakly [2] - Soda Ash: Oscillating weakly [2] - Ferrosilicon Manganese: Oscillating [4] - Ferrosilicon: Oscillating [4] 2. Core Views of the Report - Glass demand remains weak with high inventory and insufficient production cuts, leading to a weak price trend; soda ash supply is high and demand may weaken further with new capacity coming online, so the price is under pressure [1] - The supply - demand surplus in the ferrosilicon manganese and ferrosilicon industries is obvious, and losses are needed to suppress production release, with prices expected to follow the sector's fluctuations [3] 3. Summary by Directory Glass and Soda Ash - **Market Analysis**: Glass futures oscillated, and downstream procurement was cautious; soda ash futures had a narrow - range oscillation, and downstream demand was mainly for replenishing inventory [1] - **Supply - Demand and Logic**: Glass demand is weak, high inventory pressure persists, and production cuts are insufficient; soda ash supply is high, and demand may weaken further as new capacity is put into operation [1] - **Strategy**: Glass and soda ash are both expected to oscillate weakly [2] Ferrosilicon Manganese and Ferrosilicon - **Market Analysis**: Ferrosilicon manganese futures fell 0.21% to 5732 yuan/ton, and the spot price was 5650 - 5730 yuan/ton; ferrosilicon futures fell 0.14% to 5520 yuan/ton, and the spot price was slightly reduced [3] - **Supply - Demand and Logic**: Both ferrosilicon manganese and ferrosilicon have increased production and sales and reduced inventories, but the supply - demand surplus is still obvious, and losses are needed to suppress production release [3] - **Strategy**: Both ferrosilicon manganese and ferrosilicon are expected to oscillate [4]

1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - The prices of coking coal and coke are fluctuating as the price increase has not been implemented yet; glass and soda ash prices are oscillating within a narrow range due to supply disturbances; ferrosilicon and silicomanganese prices are also fluctuating with the intertwining of long - short games [1][3] - Glass is expected to be weak and oscillating, and soda ash is also expected to be weak and oscillating; silicomanganese and ferrosilicon are expected to oscillate [2][4] 3. Summary by Related Catalogs Glass and Soda Ash Market Analysis - Glass: The glass futures market oscillated within a narrow range. The spot market was mainly for rigid - demand procurement, and the speculative sentiment weakened. This week, the开工 rate of float glass enterprises was 75.34%, unchanged from the previous week, and the manufacturer's inventory was 63.606 million heavy boxes, a 0.28% increase from the previous week [1] - Soda Ash: The soda ash futures market oscillated weakly. The downstream spot market was mainly for rigid - demand replenishment. This week, the capacity utilization rate of soda ash was 88.48%, a 1.15% increase from the previous week; the output was 771,400 tons, a 1.32% increase from the previous week; and the inventory was 1.9108 million tons, a 0.9% increase from the previous week [1] Supply - Demand and Logic - Glass: The supply - demand contradiction of glass is still large. With the previous price increase, the glass output increased significantly, and the pressure to reduce high inventory is great. The premium of the futures market has been quickly repaired. In the later stage, attention should be paid to the impact of macro - policies on the supply and demand sides of glass [1] - Soda Ash: With the implementation of new production capacity in the later stage and the lack of expectation of a significant increase in soda ash consumption, the supply - demand imbalance of soda ash will continue to intensify. Therefore, it is still necessary to restrict the release of production capacity and output through losses. In the later stage, attention should be paid to the impact of changes in the supply side such as the progress of new production capacity commissioning [1] Strategy - Glass: Weak and oscillating [2] - Soda Ash: Weak and oscillating [2] Silicomanganese and Ferrosilicon Market Analysis - Silicomanganese: The long - short game sentiment in the silicomanganese futures market continued, and the market oscillated within a narrow range. The spot market quotation did not change significantly. The price of silicomanganese 6517 in the northern market was 5,700 - 5,750 yuan/ton, and in the southern market was about 5,750 - 5,800 yuan/ton [3] - Ferrosilicon: The ferrosilicon futures market oscillated within a narrow range, with a 0.28% increase. In the spot market, the market sentiment was average, and the spot price was slightly adjusted. The ex - factory price of 72 - grade ferrosilicon natural lump in the main production area was 5,300 - 5,400 yuan/ton, and the price of 75 - grade ferrosilicon was 5,800 - 5,950 yuan/ton [3] Supply - Demand and Logic - Silicomanganese: The output of silicomanganese increased month - on - month, and the inventory continued to decline, being at the median level in the same period in recent years. With the slight increase in the manganese ore quotation, the cost of silicomanganese increased. The market still shows an oversupply situation, and it is necessary to suppress the output release through a certain degree of losses. In the later stage, attention should be paid to the cost support and shipping situation of manganese ore [3] - Ferrosilicon: With the profit repair, the output of ferrosilicon increased rapidly, the demand decreased slightly week - on - week, and the inventory continued to decline. In the long run, the ferrosilicon production capacity is relatively loose. In the later stage, attention should be paid to the cost support and the impact of industrial policies on the black sector [3] Strategy - Silicomanganese: Oscillating [4] - Ferrosilicon: Oscillating [4]

Report Industry Investment Rating No relevant content provided. Core Viewpoints - Short - term supply of coking coal and coke is limited, making their prices prone to rise and hard to fall; the macro sentiment for glass and soda ash is positive, with soda ash prices rising significantly; steel prices are continuously rebounding, and ferroalloys are oscillating and consolidating [1][3] - Glass prices are expected to oscillate, and soda ash prices are also expected to oscillate; silicon manganese and silicon iron prices are expected to maintain an oscillating trend [2][5] Summary by Related Catalogs Glass and Soda Ash Market Analysis - Glass: The glass futures market showed a strong and oscillating trend yesterday. In the spot market, downstream procurement sentiment was cautious, with demand mainly for immediate needs [1] - Soda Ash: The soda ash futures market rose significantly yesterday. In the spot market, downstream transactions were stable, with a wait - and - see attitude [1] Supply - Demand and Logic - Glass: As market sentiment subsided, glass pricing returned to its fundamental logic. Currently, glass supply has not been effectively cleared, speculative demand has weakened, supply - demand remains relatively loose, and spot prices have declined. The previous premium in the futures market provided good opportunities for spot - futures arbitrage, and the rapid increase in registered glass warehouse receipts suppressed the price of the 09 contract. Attention should be paid to the impact of macro - policies on glass supply and demand [1] - Soda Ash: The market is again worried that stricter environmental inspections in Qinghai will affect local soda ash production capacity elimination. Since Qinghai has a large proportion of soda ash production capacity, if affected, it will improve the supply - demand imbalance to some extent. Currently, soda ash production is continuously increasing with further growth expected, while consumption may weaken further, and inventory growth pressure is high. Therefore, soda ash prices are easily stimulated by news in the short term, but long - term supply - demand contradictions will still suppress prices [1] Strategy - Glass: Oscillating [2] - Soda Ash: Oscillating [2] Silicon Manganese and Silicon Iron Market Analysis - Silicon Manganese: As steel prices continued to rebound, the silicon manganese futures market oscillated. In the spot market, the final pricing of mainstream steel procurement is still under negotiation. The price of 6517 silicon manganese in the northern market is 5800 - 5900 yuan/ton, and in the southern market, it is 5820 - 5920 yuan/ton [3] - Silicon Iron: The silicon iron futures market oscillated and consolidated yesterday. In the spot market, the market is waiting for HBIS's pricing. The ex - factory price of 72 - grade silicon iron natural lumps in the main production areas is 5400 - 5500 yuan/ton, and the price of 75 - grade silicon iron is 5750 - 5900 yuan/ton [3] Supply - Demand and Logic - Silicon Manganese: As market sentiment stabilized, the futures market returned to the fundamentals of the commodity. Currently, silicon manganese production and demand have slightly increased, and manufacturers' inventory has decreased month - on - month, being at a medium level compared to the same period. The quotation of manganese ore to China has slightly increased, causing the cost of silicon manganese to rise slightly, which supports the spot price. The 09 contract still has a certain discount, which also supports the futures price. However, considering the continuous increase in manganese ore port inventory, the cost support is weak, and the silicon manganese industry has an obvious supply surplus. A certain degree of loss is needed to suppress production release. It is expected that silicon manganese prices will continue to oscillate. Attention should be paid to manganese ore cost support, silicon manganese inventory, and manganese ore shipments in the future [3] - Silicon Iron: Currently, silicon iron production has rapidly increased, demand has slightly increased, and manufacturers' inventory has increased month - on - month, being at a relatively high level compared to the same period. The increase in chemical coke prices has driven up the cost of silicon iron, which supports the spot price. However, considering that the futures market is slightly at a premium, and the silicon iron industry has an obvious supply surplus, a certain degree of loss is needed to suppress production release. It is expected that silicon iron prices will continue to oscillate. Attention should be paid to cost support and the impact of industrial policies on the black sector in the future [4] Strategy - Silicon Manganese: Oscillating [5] - Silicon Iron: Oscillating [5]
