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.

Report Title - Zinc Industry Weekly Report, dated March 27, 2026 [1] Report Industry Investment Rating - Not provided Core Viewpoints - **Likely Positive Factors**: Domestic consumption is gradually picking up, spot transactions are improving, social inventories are showing signs of reduction, and the market is gradually digesting negative news. LME zinc inventories remain at a low level, and low overseas inventories provide some support for zinc prices [3]. - **Likely Negative Factors**: Zinc social inventories continue to rise to a high level, and the high inventory pressure drags down the Shanghai zinc price. The zinc ingot futures inventory on the Shanghai Futures Exchange is at a high level and increased week-on-week this week. High inventories on the supply side still suppress zinc prices [3]. - **Trading Consultation Viewpoint**: The fundamentals of Shanghai zinc are weak, and the market is highly cautious.

Report Industry Investment Rating - Not provided in the content Core Viewpoints Tin - The short - term market sentiment is volatile, and it is recommended to be cautious. There is still a long - term bullish logic for tin prices, and short - term adjustments may provide opportunities for long - term long positions [3] Copper - In the short - term, due to multiple factors, copper prices are oscillating around 100,000 yuan/ton. In the long - term, the center of copper prices is expected to rise. Short - term adjustments may provide opportunities for long - term long positions [5] Zinc - The zinc fundamentals are generally good. The price downside space may be limited without significant recession risks at the macro level. However, if the downstream production resumption in the peak season fails to meet expectations, the domestic inventory pressure may suppress the upside space [7] Industrial Silicon - The cost increase may strongly support the bottom of industrial silicon prices. In March, supply and demand are expected to be strong. Attention should be paid to the production and sales recovery and cost fluctuations [9] Polysilicon - The polysilicon market is currently oversupplied, but the low - cost photovoltaic power may be beneficial to the long - term development of photovoltaic demand. It is recommended to wait and see for now [10] Aluminum - Alumina prices are expected to continue wide - range oscillations, and short - selling on rallies is recommended. Aluminum prices are expected to oscillate at high levels in the short - term, and the long - term bullish logic remains unchanged [11] Nickel - The overseas macro uncertainty increases, and the raw material end contradictions support the price. The demand has improved slightly, but high inventory restricts the price increase. The disk is expected to oscillate strongly [12] Stainless Steel - The overseas macro risk uncertainty increases, the raw material end is tight, and the cost supports the price. The supply and demand are in a continuous game, and the short - term is expected to oscillate and adjust [16] Lithium Carbonate - The macro risk persists, and the fundamentals maintain resilience but lack strong drivers. The disk is expected to oscillate widely around the macro expectations, and it is recommended to wait and see for now [19] Aluminum Alloy - The short - term market will continue to oscillate in the context of weak supply and demand. The key turning points of the market lie in the downstream production resumption rhythm, order recovery, and scrap aluminum circulation improvement [21] Summary by Directory Tin Price and Spread - The price of Yangtze River 1 tin is 394,000 yuan/ton, down 1,350 yuan or 0.34%.

Report Summary 1. Report Industry Investment Rating - Not provided in the content 2. Core View of the Report - It is expected that Shanghai zinc will undergo wide - range adjustments, and attention should be paid to the range of 24,000 - 25,000 yuan/ton. The upstream zinc mine imports are at a high level, but domestic zinc mines are in production reduction at the end of the year. Domestic smelters' competition for domestic ore procurement has intensified, processing fees at home and abroad have dropped significantly, and the profits of domestic smelters have shrunk, with production expected to continue to be restricted. The export window may close again. The downstream market is turning to the off - season, and overall demand is weak, with only some policy - supported areas like the automobile sector showing bright spots. The spot premium is at a low level, and domestic social inventory has slightly increased, while LME zinc inventory is stable. Technically, the position has decreased and the price has adjusted, with both long and short positions trading cautiously [3][4] 3. Summary by Relevant Catalogs 3.1.
