1. Report Industry Investment Ratings No information about industry investment ratings is provided in the reports. 2. Core Views of the Reports Tin - Short - term tin prices may show a weakening oscillation due to the Middle - East war situation suppressing market risk appetite. However, the medium - to - long - term bullish logic remains. If the conflict shows signs of ending, long positions can be established at low prices [1]. Nickel - The Indonesian export tax news has brought short - term sentiment boost, but the macro - economic outlook is uncertain. The raw material supply is tight, and the inventory digestion is insufficient. The nickel price is expected to run in a relatively strong range, with the main contract referring to 134,000 - 142,000 [2]. Stainless Steel - The cost logic of stainless steel is strong recently. The news and the tight raw material supply provide support. The steel mill production is increasing, and the demand is gradually recovering but the terminal acceptance is still weak. The price is expected to maintain a relatively strong oscillation, with the main contract referring to 14,200 - 14,800 [5]. Lithium Carbonate - The supply disturbance has boosted market sentiment. The fundamental reality has weakened marginally in the short - term but still has resilience. The price is expected to run in a relatively strong range, with the main contract referring to 160,000 - 172,000 [7]. Aluminum - The alumina market is in an over - capacity stage, and the price is expected to fluctuate around the cost line. The short - term main contract is expected to run in the range of 2,800 - 3,100 yuan/ton. The electrolytic aluminum price is supported by supply - side constraints. The domestic market is expected to enter the de - stocking cycle in April, and the core operating range of Shanghai aluminum this week is expected to be 24,000 - 26,000 yuan/ton [9]. Aluminum Alloy - The casting aluminum alloy price is driven by the cost of electrolytic aluminum. It may show a pattern of weak supply and demand in the second quarter, and the short - term price is expected to run in the range of 23,000 - 24,500 yuan/ton, following the fluctuation of electrolytic aluminum [11]. Copper - The copper price is in an adjustment phase. The supply - demand fundamentals have improved slightly, and the inventory pressure has weakened. But the price is still suppressed. In the long - term, the long - cycle logic of copper supply - demand contradiction remains unchanged, and there may be opportunities for long - term long positions. The main contract should pay attention to the pressure at 97,000 - 98,000 [13]. Zinc - Zinc is in a cycle of weak supply and demand. The contradiction lies between the mine and smelting ends. The smelting cost supports the zinc price. The downstream may replenish inventory in the peak season, and the export space may be opened. The zinc price is expected to have limited room for further decline, and opportunities for price rebound on the right - hand side can be arranged [15]. Industrial Silicon - Industrial silicon has cost support at the bottom and hedging and arbitrage pressure at the top. The supply is expected to increase seasonally in the second quarter, and the demand is expected to be stable. The price is expected to oscillate around 8,000 - 9,000 yuan/ton [16]. Polysilicon - Polysilicon is in a cycle of oversupply, and the price will continue to be under pressure. It is recommended to wait and see for the time being [17]. 3.

1. Report Industry Investment Ratings No investment ratings were provided in the reports. 2. Core Views Aluminum - The current oversupply situation in the aluminum market has not been substantially reversed. Short - term strategy is to maintain a bearish view on rallies. For long - term, the global supply growth elasticity is limited, and the long - term bullish logic remains valid. The short - term aluminum price will fluctuate widely with macro - sentiment and geopolitical news, with the Shanghai Aluminum main contract expected to trade between 23,000 - 25,000 yuan/ton [1]. Aluminum Alloy - The short - term raw material cost at a high level strongly supports the ADC12 price, but the demand follows slowly and the negative feedback effect of high prices is emerging. The market is expected to continue the high - level shock pattern, with the main contract reference range of 22,000 - 23,500 yuan/ton [2]. Copper - In the short - term, the copper price is in an adjustment phase. The supply - demand fundamentals have improved and the inventory pressure has weakened. The medium - to - long - term logic of copper supply - demand contradiction has not changed significantly. The short - term adjustment may provide an opportunity for long - term long positions, but the price is still suppressed before the market risk appetite recovers significantly. The main focus is on the pressure around 97,000 - 98,000 yuan/ton [3]. Zinc - In the context of supply improvement, high inventory, and limited macro - bullish factors, the zinc price is under short - term pressure. It is recommended to pay attention to the zinc ore TC, marginal changes in demand, and macro - indicators, with the main focus on the support around 22,000 - 22,500 yuan/ton [5]. Nickel - The news of Indonesia's export tax has a short - term positive impact on sentiment. The macro - expectation is volatile. The contradiction in the raw material end supports the price, but the insufficient digestion of actual inventory is a constraint. The disk is expected to run in a strong range, with the main contract reference range of 134,000 - 142,000 yuan/ton [7]. Stainless Steel - Recently, the cost logic of stainless steel is strong. The news fermentation and the tight raw material end in reality provide support. The steel mill production has increased significantly, and the demand is gradually recovering but the terminal acceptance is still weak. It is expected to maintain a strong shock in the short - term, with the main contract reference range of 14,200 - 14,800 yuan/ton [10]. Lithium Carbonate - The war expectation is volatile, and the macro - sentiment has weakened again. The fundamentals are resilient but the marginal driving force is weakening. The mine - end disturbance still has room for fermentation, and the bottom support is still strong. It is expected to maintain range - bound fluctuations in the short - term, with the main contract reference range of 150,000 - 160,000 yuan/ton [12]. Tin - The US - Iran conflict is at a stalemate, and the market risk - aversion sentiment has resurfaced, causing the tin price to fall. The medium - to - long - term bullish logic still exists. If there are signs of the conflict ending, long positions can be established on dips [14]. Industrial Silicon - Industrial silicon is facing the pressure of oversupply with expected production growth. The cost end strongly supports the bottom. It is expected to oscillate around 8,000 - 9,000 yuan/ton. It is necessary to pay attention to production control, environmental protection, and cost - end fluctuations [15]. Polysilicon - The polysilicon market is oversupplied, and the price is expected to continue to fall. The market sentiment tends to trade for market - clearing, and the price is expected to fall towards the lowest cash cost. It is recommended to wait and see for now [17]. 3.

1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - The polysilicon market is in a cycle of oversupply, and the surplus is expected to expand, leading to continuous downward pressure on prices [3]. - Multiple companies are rumored to have production increase plans. In the context of pessimistic demand expectations, increasing the operating rate may reduce unit costs but also open up the downward space for spot prices [3]. - Whether the price will fall to the lowest cash cost (below 30 yuan/kg) as in June last year remains to be seen. The current spot average price is approaching the unit cost, and low - price products and futures prices have fallen below the unit cost and are moving towards the cash cost [3]. - The market sentiment tends to trade for market - based clearance, and the price is expected to fall towards the lowest cash cost, leaving further downward space [3]. - The industry chain is moving towards losses again. Attention should be paid to whether any enterprises will be forced out during the process of the price falling towards the lowest cash cost, as well as the impact of improved component quality on raw material requirements [3]. - In terms of trading strategies, the market is currently inactive and in a price - downward cycle, so it is recommended to wait and see [3]. 3. Summary by Relevant Catalog 3.1. Periodic and Spot Price Trends - This week, polysilicon spot quotes continued to decline significantly. The average price of N - type re -投料 decreased by 5.43% to 43.5 yuan/kg, while the N - type granular silicon stabilized at 44 yuan/kg. There is a price inversion between N - type re -投料 rod silicon and granular silicon [11]. - According to statistics from Antaike, the transaction price range of polysilicon n - type re -投料 this week is 42,000 - 45,000 yuan/ton, with an average transaction price of 43,200 yuan/ton, a 4.42% decrease from the previous week. The transaction price range of n - type granular silicon is 43,000 - 45,000 yuan/ton, with an average transaction price remaining at 44,000 yuan/ton [11]. - Trading volume and activity have both declined compared to previous weeks. The market is quiet because some large orders in March were signed at the end of February and early March, and downstream enterprises are pessimistic about the future and cautious in purchasing [11]. - The futures market broke through the support level and fell. One reason is that the falling spot price under high - inventory conditions led to the decline of futures, and the other is that the production increase expectation under high - inventory and weak - demand conditions also caused the price to break through further. On Friday, the futures closed at 37,765 yuan/ton, a significant 10% drop [7]. 3.2. Supply - Demand Situation Analysis 3.2.1 Supply - The output in February decreased to between 77,000 - 85,000 tons. According to SMM, the output in February decreased by 23,800 tons to 77,000 tons. According to the Silicon Industry Association, the domestic polysilicon output in February was about 84,400 tons, a significant 17.3% decrease from the previous month [25]. - There are 10 domestic polysilicon enterprises in production, and the industry's average operating rate has dropped to 35.5%, a 6.5 - percentage - point decrease year - on - year. The weekly output of polysilicon remained flat at 19,000 tons [25]. - In March 2026, the output is expected to increase due to more production days and the resumption of production of some enterprises. The Silicon Industry Association predicts that the total output of polysilicon in March will be between 87,000 - 89,000 tons. Although the maintenance of leading enterprises restricts the supply, the small - scale resumption of previously reduced - production capacity offsets part of the overall supply contraction [25]. - Recently, multiple companies are rumored to have production increase plans, and it is expected that the output will further increase after April, putting downward pressure on prices [25]. 3.2.2 Demand - The prices of silicon wafers and battery cells continued to decline, reflecting both cost reduction and weak long - term demand [27]. - The weekly output of silicon wafers decreased by 0.2GW to 11.78GW, and the inventory decreased by 0.7GW to 27.65GW [38]. - The output of battery cells in February decreased by about 10% to 37.09GW, slightly higher than expected, and the production plan for March is about 46.36GW [43]. - The output of components in January reached 35GW, in February it was 29.3GW, and the production plan for March has rebounded to 41.39GW [47]. - The domestic installed capacity in December was about 40.5GW. The installed capacity in the first quarter was still sluggish, but the export is expected to pick up in the first quarter [53]. 3.3. Cost - Profit Analysis - The falling polysilicon price has led to a rapid decline in profits. Although the price increase in the third quarter of last year repaired the profits, the downstream demand has been continuously weak, and there is no obvious sign of recovery in the first quarter of 2026. The recent price decline and demand drop have made the overall profit outlook still not optimistic [62]. - Daquan Energy's February investor interaction record released on March 4 shows that in the fourth quarter of 2025, the unit cash cost of polysilicon decreased to 33.95 yuan/kg, and the unit cost decreased to 43.46 yuan/kg. In 2025, the company achieved an operating income of 4.83 billion yuan, with a net profit attributable to the parent company of - 1.13 billion yuan, and the loss amplitude narrowed significantly year - on - year. The company's production and sales rate reached 103%, and the inventory was maintained at a reasonable level, with continuous optimization of asset operation efficiency [62]. - Referring to Daquan Energy, Tongwei and GCL have relatively more cost advantages, opening up the expectation space for the futures market [62]. 3.4. Import - Export - In January and February 2026, the imports of polysilicon were 1,047 tons and 1,222 tons respectively, and the exports were 1,838 tons and 2,215 tons respectively. It has been a net exporter since the beginning of the year [65]. - From January to February 2026, the export volume of silicon wafers increased, the import volume decreased, and the net export was 6,736 tons [73]. - From January to February 2026, the export volume of battery cells decreased month - on - month but increased year - on - year, with a 20% year - on - year increase in February. The exports of components decreased [77]. 3.5. Inventory and Warehouse Receipt Changes - The weekly inventory decreased by 13,000 tons to 344,000 tons. The warehouse receipts decreased by 880 lots to 9,810 lots, equivalent to 29,430 tons [88].

1. Report Industry Investment Ratings No information about the report industry investment ratings is provided in the content. 2. Core Views of the Report Zinc - Overseas monetary policy tightening expectations put pressure on market risk appetite, and spot trading improvement is limited. Zinc prices oscillated and adjusted. The shortage of zinc ore supports prices, but the high zinc prices suppress demand. The overall fundamentals are good, and the downside space of zinc prices may be limited. Pay attention to the changes in zinc ore TC and refined zinc inventory [2]. Copper - The expectation of copper storage at home and abroad is strengthened, and copper prices stabilized and rebounded. The short - term supply of copper ore is tight, and the demand has recovered. The medium - and long - term logic remains unchanged, and the bottom center of copper prices is expected to rise gradually. In the short term, with the narrowing of CL premium, copper prices may return to fundamental pricing [5]. Tin - The short - term tin prices are easily affected by market sentiment and may fluctuate sharply. In the medium and long term, although the supply side is gradually recovering, considering the low elasticity of supply and the long - term narrative of the AI arms race, a low - buying strategy for tin prices is recommended [7]. Aluminum - Alumina prices are expected to continue to fluctuate widely around the industry cost line. Aluminum prices have experienced an emotional surge, but they have deviated from fundamental support. It is recommended to gradually make long positions after the price stabilizes and the volatility decreases [9]. Nickel - Recent macro - sentiment and ore - end expectations affect the overall fluctuation rhythm of nickel prices. Nickel prices are expected to adjust in a wide range. Pay attention to the range of 130,000 - 140,000 [11]. Stainless Steel - Stainless steel mainly follows the macro - sentiment. The cost support still exists, but the supply contraction due to steel mill production cuts, the weak demand boost in the off - season, and inventory digestion are still insufficient. It is expected to adjust weakly in the short term [13]. Industrial Silicon - Industrial silicon prices are expected to oscillate, with the main price fluctuation range between 8,200 - 9,200 yuan/ton. Pay attention to the changes in production and demand [15]. Polysilicon - Production enterprises have a strong willingness to support prices. Polysilicon prices are expected to stabilize and oscillate. Pay attention to the post - Spring Festival production reduction and downstream demand recovery [17]. Aluminum Alloy - The ADC12 price of aluminum alloy is expected to continue to oscillate in the high - level range. Pay attention to the actual circulation of scrap aluminum, the change of import window, and the final strength and rhythm of downstream inventory preparation before the Spring Festival [18]. Lithium Carbonate - The trading logic of lithium carbonate has switched, and the macro impact is greater. The price center has a certain constraint on the downward adjustment space. It is expected to adjust in a wide range in the short term [19]. 3. Summaries According to Relevant Catalogs Zinc - **Price and Spread**: SMM 0 zinc ingot price increased by 0.32% to 25,050 yuan/ton.

In the medium - to - long - term, although the supply side is gradually recovering, considering the low elasticity of the supply end and the long - term narrative of the AI arms race, a low - buying strategy for tin prices is recommended [2]. Copper - In the short term, if the CL premium reverses, COMEX copper inventory may flow back to non - US regions, alleviating supply pressure there; if it remains narrow, copper prices may fluctuate in a wide range with limited upward potential, and if it widens, copper prices may maintain a relatively strong trend. In the medium - to - long - term, the price bottom is expected to rise gradually under the constraint of capital expenditure on the supply side, but current prices are suppressing downstream demand, and price fluctuations may intensify [3]. Zinc - The weakening of the US dollar index supports zinc prices. The shortage of zinc ore at the mine end supports prices, and the supply pressure of refined zinc is easing. The demand side has shown a significant recovery in the processing industry's operating rate after the price correction, and the terminal orders are stable. The global zinc ingot inventory pressure is limited. Short - term prices have limited downside space, and it is recommended to focus on the changes in zinc ore TC and refined zinc inventory, with the main contract supported at around 25,000 - 25,500 yuan/ton [5]. Industrial Silicon - The spot price of industrial silicon is stable, and the futures price has risen following commodities like coking coal. In January, both supply and demand have weakened slightly, with a slight inventory build - up. It is necessary to pay attention to the production reduction situation of industrial silicon. The price is expected to fluctuate in the range of 8,200 - 9,200 yuan/ton, with the upper limit pressured by the opening of the arbitrage window and the lower limit supported by costs [7]. Polysilicon - The polysilicon spot price is stable, but downstream components and battery cells are still reducing production despite price increases and increased exports due to weak domestic demand and the approaching Spring Festival. The demand for polysilicon is low, and the price is under pressure. In February, there is still pressure to reduce production. It is recommended to wait and see, focusing on the production reduction process and downstream demand recovery [8]. Aluminum - The alumina market is affected by the overall risk - preference recovery in the commodity market and supply - contraction expectations, but the high - inventory pressure in the domestic spot market still suppresses prices. It is expected to continue to fluctuate widely around the industry's cash - cost line. The aluminum market has shown a high - level breakthrough, but the domestic fundamentals are under pressure. In the medium - to - long - term, aluminum prices are expected to be strong and difficult to fall, but there is a risk of a high - level correction in the short term [9]. Aluminum Alloy - The casting aluminum alloy market has followed the rise in aluminum prices but lacks financial attributes and has poor downstream acceptance. The cost is the main driving factor, and the fundamentals show a typical seasonal supply - and - demand weakness. It is expected that the ADC12 price will continue to oscillate in the high - level range of 22,500 - 24,500 yuan/ton in the short term [11]. Nickel - The nickel market is supported by the strong performance of the non - ferrous sector and the smelters' hoarding mentality due to the expected tight supply of raw materials. In the short term, the price is expected to oscillate strongly in the range of 145,000 - 155,000 yuan/ton [12]. Stainless Steel - The stainless - steel market is driven by the strong commodity sentiment and the improvement in fundamentals due to steel - mill production cuts. In the short term, it is expected to adjust in a strong - oscillation pattern, with the main contract in the range of 14,200 - 15,200 yuan/ton. It is necessary to pay attention to the news from the ore end and the dynamics of steel mills [14]. Lithium Carbonate - The lithium carbonate futures market has shown a weak adjustment. Although the fundamentals show certain inventory - reduction resilience during the off - season, which supports prices, there may be a short - term decline adjustment. It is recommended to operate cautiously in the range of 155,000 - 170,000 yuan/ton [17]. 3.

Report Industry Investment Ratings No information about industry investment ratings is provided in the reports. Core Views Tin - Short - term tin prices are highly volatile due to market sentiment, so cautious participation is advised. In the medium - to - long - term, the supply side is gradually recovering, but considering the low elasticity of the supply side and the long - term narrative of the AI arms race, a low - buying strategy for tin prices is recommended [2]. Industrial Silicon - The spot price of industrial silicon is stable, and the futures price fluctuates, rising after a decline. The production in January and February is expected to decrease. The demand side is likely to decline slightly in January. The price of industrial silicon is expected to fluctuate, with the main price range between 8200 - 9200 yuan/ton. Attention should be paid to the changes in production on the demand side [3]. Polysilicon - The average spot price of polysilicon and the price of silicon wafers have declined. The demand expectation has improved, and component production may increase slightly, which is conducive to inventory digestion. However, polysilicon and silicon wafer prices are under pressure due to high inventory. The monthly average production in the first quarter is expected to drop to about 80,000 tons. The price may be supported at the 48,000 yuan/ton level, and even at 45,000 yuan/ton considering full - cost support [4]. Copper - Market speculative sentiment has eased, and copper prices fluctuated. Geopolitical factors affect market expectations of copper tariffs. The global visible inventory has reached a high level in recent years, and the return of COMEX copper inventory may ease the supply pressure in non - US regions. In the short term, copper prices may return to fundamental pricing, and in the long term, the price bottom center is expected to gradually rise. Attention should be paid to the CL premium and LME inventory changes, with support at 97500 - 98500 [5]. Zinc - Market speculative sentiment has eased, and zinc prices adjusted. The shortage of zinc ore supports prices, and the import window for zinc ore has opened. The supply pressure of refined zinc has been relieved. High zinc prices have suppressed demand, and the downstream operating rate has weakened. Zinc prices are expected to fluctuate in the short term, with support around 23,800. Attention should be paid to zinc ore TC and refined zinc inventory changes [9]. Aluminum - The alumina market showed a weak and volatile trend, with an oversupply situation. Alumina prices are expected to fluctuate widely around the industry's cash - cost line, with the main contract reference range of 2600 - 2900 yuan/ton. The aluminum market is in a high - level volatile pattern. Although macro and policy expectations are positive, the fundamentals are under pressure, with supply increasing and demand being suppressed. Aluminum prices are expected to remain volatile at a high level in the short term, with the main contract reference range of 23000 - 25000 yuan/ton [12]. Nickel - The nickel futures market was volatile. Macro factors and the situation of Indonesian nickel ore quotas affect the market. The overall spot transaction of refined nickel is average. The prices of nickel ore and nickel iron have increased. The demand for stainless steel in the off - season is weak, and the market cost is relatively limited. The inventory pressure has increased. The nickel price is expected to fluctuate widely, with the main contract reference range of 138000 - 148000 [13]. Aluminum Alloy - Cast aluminum alloy prices fluctuated at a high level, with cost being the main driving factor. The supply of scrap aluminum is still tight, and the fundamentals show a situation of weak supply and demand in the off - season. The social inventory has decreased slightly. The ADC12 price is expected to continue the high - level volatile pattern in the short term, with the main contract reference range of 22000 - 23500 yuan/ton [15]. Stainless Steel - Stainless steel prices showed a narrow - range fluctuation and then a late - session rally. Macro factors and raw material supply expectations affect the market. The raw material prices are expected to rise, the supply is relatively loose, and the demand is weak. The social inventory is decreasing, but the demand in the off - season is still insufficient. Stainless steel prices are expected to be strongly volatile in the short term, with the main contract reference range of 14200 - 15000 [16]. Lithium Carbonate - Lithium carbonate futures prices rose sharply. News about lithium concentrate auctions and mine supply fluctuations affected the market sentiment. The production is slightly increasing, and the supply is expected to decline during the pre - holiday maintenance period. The downstream demand shows certain resilience. Social inventory decreased last week. Lithium carbonate prices are expected to be strongly volatile in the short term, but chasing the rise requires attention to volatility and liquidity risks [20].

1. Report Industry Investment Ratings No information provided in the reports regarding industry investment ratings. 2. Core Views Tin - Short - term price is highly volatile due to market sentiment. After a sharp decline on Friday night, it's advisable to be cautious in the short - term. Consider a low - buying strategy after the sentiment stabilizes [1]. Copper - In the long - term, the price bottom center is expected to rise due to capital expenditure constraints on the supply side. In the short - term, the price is strong because of global inventory structural imbalance and supply concerns. However, real terminal demand is weak. With the cooling of speculative sentiment and easing of tariff expectations, the price may return to fundamental pricing.
