1. Report Industry Investment Rating - Not provided in the given content 2. Core Views - The supply and demand of steel are both weakening, and steel prices are fluctuating. Glass and soda ash are experiencing range - bound oscillations due to pre - holiday cautious sentiment. For double silicon, the market is mainly in a wait - and - see mode as the Spring Festival approaches [1][3] - Glass market fundamentals have no obvious improvement. Although the expected production halt in Shahe eases supply pressure, pre - holiday demand is weak, and inventory is accumulating. Soda ash supply is abundant with new production projects advancing, and pre - holiday demand is seasonally low [1] - The fundamentals of silicon manganese have improved slightly with expected increase in iron - water production, but inventory pressure remains high. The fundamentals of silicon iron are controllable, and demand is expected to improve marginally as steel mills resume production, but overall over - capacity restricts price increases [3] 3. Summary by Related Catalogs Glass and Soda Ash Market Analysis - Glass contracts showed narrow - range fluctuations yesterday, with decreasing positions as the holiday nears. Spot prices are stable, but trading volume is low. This week, cold - repair of production lines increased, daily melting volume dropped, and inventory rose. Soda ash contracts also had narrow - range fluctuations, with low spot trading volume. This week, soda ash production increased slightly, heavy - ash inventory rose slightly, and light - ash inventory decreased [1] Supply - Demand and Logic - Glass fundamentals have no significant improvement. The expected production halt in Shahe eases supply pressure, but pre - holiday demand is weak, and inventory accumulation continues. Soda ash supply is in a loose pattern. With new production projects advancing, production remains high, and inventory is increasing. Pre - holiday demand drops seasonally, and the new production projects need to be monitored [1] Strategy - Glass: Range - bound fluctuations; Soda ash: Range - bound fluctuations; No strategies for inter - period and inter - variety trading [2] Double Silicon Market Analysis - Silicon manganese futures continued to fluctuate slightly, and the market was quiet with a strong holiday atmosphere. The price of 6517 silicon manganese is 5580 - 5680 yuan/ton in the northern market and 5700 - 5750 yuan/ton in the southern market. Silicon iron futures followed the overall black - metal market downwards, and the spot market was weak. Most of the market is in a wait - and - see mode. The price of 72 - grade silicon iron in the main production areas is 5250 - 5350 yuan/ton, and that of 75 - grade silicon iron is 5850 - 6000 yuan/ton [3] Supply - Demand and Logic - Silicon manganese fundamentals have improved slightly, and iron - water production is expected to increase, leading to marginal improvement in demand. However, inventory pressure is still high. The South African tariff policy may increase manganese ore costs. Silicon iron fundamentals are controllable. Enterprises are reducing production, and demand is expected to improve as steel mills resume production. But overall over - capacity restricts price increases, and inventory reduction and power - price policies need to be monitored [3] Strategy - Silicon manganese: Range - bound fluctuations; Silicon iron: Range - bound fluctuations [4]

1. Report Industry Investment Rating - Not provided in the given content 2. Core Viewpoints of the Report - The market sentiment is average, and steel prices are fluctuating weakly. The supply - demand contradictions in the glass and soda ash markets remain unresolved, leading to wide - range fluctuations. For double - silicon, the pre - holiday replenishment is nearing the end, causing significant declines in double - silicon futures [1][3] - Glass is expected to show an oscillatory trend, while soda ash is expected to oscillate weakly. Both silicon manganese and silicon iron are expected to show an oscillatory trend [2][4] 3. Summary by Related Catalogs Glass and Soda Ash Market Analysis - Glass: The main glass contract showed wide - range fluctuations yesterday, with the open interest steadily increasing as the market rebounded and high market activity. Spot prices fluctuated with the market, and downstream buyers mainly made purchases based on rigid demand [1] - Soda Ash: The main soda ash contract showed a weak - oscillatory trend yesterday, with obvious multi - short game. The short - position open interest increased, spot prices stabilized, and buyers mainly replenished stocks based on rigid demand [1] Supply - Demand and Logic - Glass: Glass production decreased slightly year - on - year due to cold - repair and production cuts, alleviating supply pressure and providing some support for prices. However, the downstream is still in the traditional off - season, and the inventory - replenishment sentiment is low, limiting the upside space for prices. The absolute glass price is currently low, and the tolerance for inventory during the Spring Festival is high. The fundamental contradictions have not been effectively resolved [1] - Soda Ash: The current production of soda ash is high, and with the advancement of new projects, the supply - side pressure is increasing. Downstream consumption shows a seasonal decline as cold - repair increases. The total inventory of domestic soda ash manufacturers remains at a high level, and the de - stocking process is slow, resulting in significant supply - demand contradictions [1] Strategy - Glass: Oscillatory [2] - Soda Ash: Weakly oscillatory [2] Double - Silicon (Silicon Manganese and Silicon Iron) Market Analysis - Silicon Manganese: As the Chinese New Year approaches, raw - material replenishment is nearing the end, and the silicon manganese futures dropped significantly yesterday. The silicon manganese market is oscillating, with strong market wait - and - see sentiment at the beginning of the week. The mainstream steel procurement has not yet started. The price of 6517 silicon manganese in the northern market is 5580 - 5680 yuan/ton, and in the southern market is 5720 - 5770 yuan/ton [3] - Silicon Iron: The silicon iron futures followed the overall downward trend of the black - metal market yesterday. The silicon iron market is operating weakly, with strong cautious wait - and - see sentiment. The ex - factory price of 72 - grade silicon iron natural lumps in the main production areas is 5250 - 5350 yuan/ton, and the price of 75 - grade silicon iron is 5850 - 6000 yuan/ton [3] Supply - Demand and Logic - Silicon Manganese: The fundamentals of silicon manganese have improved, and there is an expectation of an increase in hot - metal production in the future, leading to a marginal improvement in silicon manganese demand. However, the inventory pressure is still large, and the supply - demand pattern remains relatively loose. The recent tariff policy in South Africa may increase the cost of manganese ore, so attention should be paid to the cost support of manganese ore and inventory changes [3] - Silicon Iron: The fundamental contradictions of silicon iron are controllable, and enterprises are actively reducing production loads. Considering the resumption of production by steel mills, the demand for silicon iron is expected to improve marginally. The overall over - capacity of silicon iron suppresses the price increase. Continuous attention should be paid to the de - stocking situation of silicon iron and the electricity - price policy in the production areas [3] Strategy - Silicon Manganese: Oscillatory [4] - Silicon Iron: Oscillatory [4]

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]

1. Report Industry Investment Ratings No information provided in the reports regarding industry investment ratings. 2. Core Views of the Reports Steel Industry - Steel prices are expected to maintain a volatile trend. The upward potential depends on coking coal supply - side policies and market sentiment. It is recommended to hold the long position of the spread between hot - rolled coil and rebar and look for short - term long opportunities for hot - rolled coil at the 3250 level [1]. Iron Ore Industry - Before the Spring Festival, iron ore demand is weak. High inventory and high - level supply during the off - season continue to put pressure on prices. It is expected that the price will fluctuate weakly in the short term, and short - selling can be attempted, but be vigilant about macro and market sentiment disturbances [3]. Coke and Coking Coal Industry - For coke, the price increase has been implemented, which drives the market to rebound. However, the lag in the implementation time of price increases by mainstream coke enterprises dampens the expectation of future price increases. After the Spring Festival, there is still an expectation of supply loosening. It is recommended to view it as a unilateral volatility with a reference range of 1600 - 1800, and the arbitrage strategy is to go long on coking coal and short on coke. - For coking coal, the market has a re - evaluation of its value, but the domestic supply - demand is generally balanced. It is also recommended to view it as a unilateral volatility with a reference range of 1050 - 1250, and the arbitrage strategy is to go long on coking coal and short on coke [6]. Ferrosilicon and Ferromanganese Industry - For ferrosilicon, the short - term supply - demand contradiction is limited, the fundamentals are relatively healthy, and there is cost support. It is expected that the price will fluctuate widely in the range of 5500 - 5800, taking into account macro - sentiment fluctuations. - For ferromanganese, it is in a situation of weak supply and demand. After the Spring Festival, there is still an expectation of production resumption, and the fundamentals lack strength. It is expected that the price will fluctuate widely in the range of 5600 - 6000, paying attention to macro - sentiment fluctuations [7]. 3. Summary According to Relevant Catalogs Steel Industry Prices and Spreads - Rebar and hot - rolled coil prices: Rebar spot prices in different regions (East China, North China, South China) and futures contract prices (05, 10, 01) have different changes.

1. Report Industry Investment Ratings No information provided in the reports. 2. Core Views of the Reports Steel Industry - The steel industry shows low and stable production, declining apparent demand, seasonal inventory accumulation with a lower - than - year - on - year rate. Rebar continues to accumulate inventory while hot - rolled coils maintain de - stocking. Steel prices fluctuate with market sentiment, staying in a range. The spread between hot - rolled coils and rebar widens, and the basis of rebar weakens while that of hot - rolled coils strengthens. In February, due to the Spring Festival off - season, supply and demand are weak. Steel prices are expected to continue seasonal inventory accumulation, with de - stocking pressure after the festival. The price is constrained by weak domestic demand on the upside and supported by macro sentiment and supply - side policies on the downside. Rebar is expected to fluctuate between 3050 - 3250 yuan, and hot - rolled coils between 3200 - 3350 yuan [1]. Iron Ore Industry - Iron ore is in a situation of strong supply and weak demand. With high inventory, stagnant resumption of iron - making production, and the fulfillment of steel mills' restocking, iron ore prices are under pressure. Supply shows a marginal decrease in the shipping center but is still at a relatively high level compared to historical periods. Demand sees a slight decline in iron - making production and a drop in steel mills' profitability. Terminal demand for steel exports weakens, and the manufacturing industry faces an off - season. Before the Spring Festival, it is difficult to resume iron - making production, and negative feedback is also hard to observe. Port inventory continues to accumulate, and steel mills' inventory increases significantly. Before the Spring Festival, the price is expected to be under pressure, and one can try short - selling around 800 yuan, but beware of macro and market sentiment disturbances [3]. Coke and Coking Coal Industry - Coke futures showed a trend of rising first and then falling in January. The fourth - round price cut of coke was implemented on January 1st, followed by price increases from major coke producers. The first - round price increase was officially accepted by steel mills on January 28th and executed on the 30th. The supply side has lagging price adjustments of coke compared to coking coal, resulting in pressure on coking profits and a slight decline in production. The demand side has a slight resumption of production by steel mills after New Year's Day, with low - level iron - making production and a rebound in steel prices. In terms of inventory, coke - making plants and steel mills accumulate inventory, while ports reduce inventory. The overall inventory is slightly increased at a medium level, and the supply - demand situation of coke improves. Before the Spring Festival, the market is expected to be volatile and slightly strong, with a reference range of 1650 - 1850 yuan. - Coking coal futures also showed a trend of rising first and then falling. Spot prices in Shanxi showed signs of decline, and Mongolian coal prices fluctuated with futures. The supply side has an increase in daily coal output from mines and faster de - stocking. Imported coal has a high - level inventory at ports, and the customs clearance of Mongolian coal has rebounded rapidly after New Year's Day. The demand side has limited growth in demand for downstream restocking before the Spring Festival due to low - level iron - making production, declining coking profits, and reduced production. In terms of inventory, coke - making plants, steel mills, and ports accumulate inventory, while mines, coal - washing plants, and ports reduce inventory. The overall inventory is slightly increased at a medium level. The market is expected to be volatile and slightly strong before the Spring Festival, with a reference range of 1050 - 1250 yuan. An arbitrage strategy of going long on coking coal and short on coke is recommended, but beware of the supply - demand situation turning loose after the festival [5]. Ferrosilicon and Ferromanganese Industry - For ferrosilicon, supply shows a slight decline, with stable production recently and an increase in the operating rate of manufacturers. The absolute weekly production is at a historically low level. Inner Mongolia's production rises steadily, Ningxia's production is stable, and southern regions may see a contraction in production due to potential electricity price hikes. Steel - making demand is expected to have stable iron - making production before the Spring Festival. The contradiction in the finished - product market is relatively limited, and the resumption of iron - making production can suppress inventory contradictions. However, the resumption space is limited by off - season demand, and negative feedback is hard to observe. The inventory in factories is still high, mainly concentrated in Ningxia, but the warehouse - receipt level is relatively low. The cost of alloy manufacturers' coal - mine replenishment is rising. The overall non - steel demand is marginally weakening. In the short term, the supply - demand contradiction of ferrosilicon is limited, and the fundamentals are relatively healthy. The cost side also provides support. The price is expected to fluctuate widely, and attention should be paid to macro - sentiment fluctuations [6]. - For ferromanganese, supply has a slight increase in production, basically remaining stable from the previous period. Most production areas' output is flat compared to last week, with a slight increase in Ningxia's output. Inner Mongolia's settlement electricity price in January is expected to rise, and attention should be paid to the change in settlement electricity prices in other production areas. Before the Spring Festival, the production of ferromanganese is expected to be stable. Steel - making demand is expected to have stable iron - making production before the Spring Festival. The contradiction in the finished - product market is relatively limited, and the resumption of iron - making production can suppress inventory contradictions. However, the resumption space is limited by off - season demand, and negative feedback is hard to observe. Hebei Iron and Steel Group's next - month procurement volume is reduced compared to last month, and attention should be paid to the pricing. The non - steel demand is weakening, and the price is falling. The cost of manganese ore is expected to rise, but the increase is limited. In the short term, the high inventory still suppresses the price, and the fundamentals lack impetus. The price of ferromanganese is expected to fluctuate widely, with a reference range of 5600 - 6000 yuan, and attention should be paid to macro - sentiment fluctuations [6]. 3.

1. Report Industry Investment Ratings - No industry investment ratings are provided in the given reports. 2. Core Views Steel - Steel prices maintain a sideways trend, with rebar slightly stronger than hot - rolled coils, and the spread between coils and rebar has converged to 160 yuan per ton. The steel industry has weak supply and demand. Rebar demand declines seasonally, with a large supply - demand gap and obvious inventory accumulation; hot - rolled coil demand declines slightly and inventory continues to be depleted. The market sentiment has improved in the second half, and steel is expected to fluctuate towards the upper limit of the range. The 5 - month contract of rebar is expected to fluctuate between 3050 - 3250 yuan, and hot - rolled coils between 3200 - 3350 yuan [1]. Iron Ore - Iron ore is facing a pattern of weak supply and demand. With the possible easing of the negotiation deadlock, lower - than - expected hot - metal production resumption, and the gradual realization of steel - mill restocking, prices are under pressure. Be cautious of macro - level fluctuations [3]. Coke - The coke futures showed a trend of first falling and then rising last week. The spot market is currently stable. Supply - side price adjustments lag behind coking coal, and coking profits are under pressure. Demand - side steel - mill production has resumed slightly after the New Year's Day. Inventory has increased slightly. After the fourth round of spot price cuts, some coke enterprises are resisting price cuts and starting to raise prices, which is expected to be implemented. The market is expected to be loose again, and prices are expected to fluctuate within the range of 1600 - 1800 yuan [5]. Coking Coal - Coking coal futures also showed a trend of first falling and then rising last week. The spot auction prices in Shanxi mostly increased, and the Mongolian coal quotation followed the futures down. The supply side has resumed production, and the demand side has low - level hot - metal production and weakening coking profits. The overall inventory has increased slightly. Before the Spring Festival, the spot is strong due to restocking demand, but the futures have over - anticipated the rise. After the festival, the market is expected to be loose, and prices are expected to fluctuate within the range of 1000 - 1200 yuan [5]. Ferrosilicon - Ferrosilicon is in a pattern of weak supply and demand. Supply is stable, and production is at a historically low level. The non - steel demand is weakening. The overall inventory is moderately high. The cost is affected by the manganese ore restocking. In the short term, the price is expected to fluctuate widely within the range of 5500 - 5900 yuan [6]. Silicomanganese - Silicomanganese supply is relatively stable with a low absolute value. The demand is affected by the slow resumption of hot - metal production. The manganese ore supply and port inventory have an impact on the cost. The price is expected to fluctuate widely within the range of 5600 - 6000 yuan [6]. 3.

Group 1: Overall Market Situation - The fundamentals of steel are under continued pressure, and steel prices are fluctuating [1] Group 2: Glass and Soda Ash Market Analysis - Glass futures fluctuated and rose yesterday, while the spot market quotes remained stable, with dull production and sales by manufacturers and a cold trading atmosphere in the spot and futures markets This week, the inventory of float glass manufacturers was 53.216 million heavy boxes, a 0.38% increase from the previous week [2] - Soda ash futures also fluctuated and rose yesterday, with limited rigid demand procurement from downstream. This week, the soda ash inventory was 1.5212 million tons, a 1.49% decrease from the previous week [2] Supply - Demand and Logic - The supply - demand contradiction in the glass market is still significant. Although some production lines have been gradually cold - repaired, the production reduction is still insufficient compared to the decline in rigid demand. With the procurement by spot - futures traders, the inventory pressure is expected to ease, and the market anticipates a peak season after the Spring Festival. Attention should be paid to the progress of glass cold - repair [2] - The supply - demand contradiction in the soda ash market is relatively limited. Some soda ash plants have completed maintenance, and supply has increased. Considering the upcoming new production projects in the future and the expected increase in cold - repair of float glass production lines, it is necessary to suppress the production profit of soda ash enterprises to avoid supply - demand imbalance. In the short term, the speculative demand for soda ash has increased under the influence of macro - sentiment. Attention should be paid to the changes in float glass production lines and the progress of new soda ash production projects [2] Strategy - The glass market is expected to be in a state of fluctuation, while the soda ash market is expected to fluctuate weakly [3] Group 3: Silicon Manganese and Silicon Ferrosilicon Market Analysis - The main contract of silicon manganese opened lower and moved higher yesterday, with trading volume increasing as the market fluctuated at a high level. The cost support for the alloy is acceptable. The price of 6517 silicon manganese in the northern market is 5,570 - 5,680 yuan/ton, and in the southern market is 5,700 - 5,750 yuan/ton [4] - The silicon ferrosilicon futures fluctuated strongly yesterday, and the market adjusted slightly, with strong cautious waiting - and - seeing sentiment. The ex - factory price of 72 - grade natural block silicon ferrosilicon in the main production areas is 5,200 - 5,250 yuan/ton, and the price of 75 - grade silicon ferrosilicon is 5,800 - 5,850 yuan/ton [4] Supply - Demand and Logic - The fundamentals of silicon manganese have improved, but the inventory pressure is still large, and there are new production capacities coming on - stream, so the supply - demand is still relatively loose. There is an expectation of an increase in pig iron production in the future, and combined with the expectation of steel mills' inventory replenishment before the Spring Festival, the demand for silicon manganese is expected to improve. The recent tariff policy changes in South Africa may increase the cost of manganese ore. Attention should be paid to the cost support of manganese ore and production changes [4] - The fundamental contradictions of silicon ferrosilicon are controllable, and enterprises have actively reduced production loads. Considering the resumption of production by steel mills and winter - storage inventory replenishment, the demand for silicon ferrosilicon is expected to improve. The differential electricity price policy implemented in Shaanxi in the second half of the year has affected market sentiment, but considering the expected further decline in domestic electricity prices this year and the overall over - capacity of silicon ferrosilicon, the price increase is limited. Attention should be paid to the inventory reduction of silicon ferrosilicon and the electricity price policies in production areas [4] Strategy - Both the silicon manganese and silicon ferrosilicon markets are expected to be in a state of fluctuation [5]

1. Report Industry Investment Ratings - No investment ratings are provided in the reports. 2. Core Views of the Reports Steel Industry - The steel market shows weak supply and demand. The seasonal decline in rebar demand is significant, while the decline in hot - rolled coil demand is relatively small. The recent cost reduction may lead to a downward shift in the steel price center. The reference range for the May rebar contract is 3050 - 3250 yuan, and for hot - rolled coils, it is 3200 - 3350 yuan. Consider closing long positions on the steel - to - ore ratio when it rises, and continue to hold long positions on the hot - rolled coil to rebar spread [1].

Coking Coal Industry - The coking coal market shows a pattern of increasing supply and demand. Before the Spring Festival, the spot market is strong due to restocking demand, but the futures market has over - anticipated the price increase. After the Spring Festival, the market supply and demand are expected to be loose, and the price is expected to fluctuate within the range of 1000 - 1200 yuan [7]. Ferrosilicon Industry - The short - term supply - demand contradiction of ferrosilicon is limited, lacking upward drivers at the industrial level. The price is expected to fluctuate slightly within the range of 5300 - 5800 yuan, with short - term attention to macro and policy factors [8]. Ferromanganese Industry - Ferromanganese is in a situation of weak supply and demand. The price is expected to fluctuate within the range of 5800 - 6000 yuan, with short - term attention to macro and policy factors [8]. 3.

1. Report Industry Investment Ratings No investment ratings are provided in the reports. 2. Core Views of the Reports Steel Industry - The steel industry shows a pattern of weak supply and demand. Before the Spring Festival, domestic demand is weak, and prices have fully factored in the weak demand. The decline in production and the accumulation of raw materials have led to a weakening of raw material prices, and the recent cost reduction may cause the steel price center to shift downwards. The reference range for the May contract of rebar is 3050 - 3250 yuan/ton, and for hot - rolled coils, it is 3200 - 3350 yuan/ton. It is recommended to hold long positions in the steel - to - iron ore ratio and long positions in the hot - rolled coil to rebar price spread [1]. Iron Ore Industry - The iron ore market faces a situation of weak supply and demand. The price is constrained by high inventory on the upside and supported by the expectation of steel mill restocking on the downside. In the short term, attention should be paid to the resumption of iron - making production, macro - level narratives, and the rhythm of steel mill restocking. In the long term, negotiation situations need to be monitored. It is expected that the iron ore price will fluctuate widely, with a recommended trading range of 770 - 830 [3]. Coke and Coking Coal Industry - For coke, after the fourth round of spot price cuts, some coke enterprises are resisting further price cuts and are considering production cuts to maintain prices. The mainstream coke enterprises have initiated a price increase, which is expected to be implemented. The futures price of coke has fallen in advance, and the spot price decline depends on the decline of coking coal. It is recommended to be bearish on the futures price and consider an arbitrage strategy of long coking coal and short coke. - For coking coal, although there is a demand for spot restocking before the Spring Festival, the futures price has already factored in the increase. After the Spring Festival, the market supply and demand are expected to be loose. It is also recommended to be bearish on the futures price and consider an arbitrage strategy of long coking coal and short coke [5]. Ferrosilicon and Ferromanganese Industry - Ferrosilicon: In the short term, the supply - demand contradiction is limited, and there is a lack of upward momentum at the industrial level. It is expected that the price will fluctuate widely, with a reference range of 5300 - 5800 yuan/ton. Attention should be paid to macro - level and policy - related narratives. - Ferromanganese: It is in a situation of weak supply and demand. High inventory suppresses the price in the short term, but manganese ore provides support. It is expected that the price will fluctuate widely, with a reference range of 5600 - 6000 yuan/ton [6]. 3.
