Group 1: Report Industry Investment Ratings - Not provided in the given content Group 2: Core Views of the Report - Copper: With the S232 investigation pending, the US copper market may continue to attract copper from other regions, leading to a tight - balance situation with low inventories and potential squeezes for both SHFE and LME copper. After the investigation results are out, the market narrative may reverse [1] - Aluminum: Supply has a slight increase, and in July, demand is expected to weaken seasonally. The market is expected to be balanced in terms of supply and demand. The short - term fundamentals are okay, and attention should be paid to demand and low - inventory arbitrage opportunities [1] - Zinc: Zinc prices fluctuated upwards this week, mainly due to high macro - sentiment. The supply is expected to increase, and demand is weakening seasonally. The short - term strategy is to short zinc on rebounds and hold long - short spreads between domestic and overseas markets [2] - Nickel: The supply of pure nickel remains high, and demand is weak. The short - term fundamentals are average, and opportunities to shrink the nickel - stainless steel price ratio can be continuously monitored [6] - Stainless Steel: Supply has been reduced since late May, demand is mainly for rigid needs, and the overall fundamentals are weak, with prices expected to oscillate weakly in the short term [7] - Lead: Lead prices rebounded from a low level this week, which was due to speculation. The supply in July is expected to slightly decrease, and demand is weak. The price is expected to oscillate between 16,800 - 17,300 [8] - Tin: Tin prices fluctuated upwards this week, driven by commodity sentiment. The supply is disturbed, and demand is expected to decline. The market is expected to be in a state of weak supply and demand in the short term, and long - positions can be cautiously held [11] - Industrial Silicon: With significant production cuts by leading enterprises, the supply - demand balance has shifted to inventory reduction. The price is expected to oscillate strongly in the short term, and in the long - term, it will be mainly based on the cash - flow cost of leading enterprises [14] - Lithium Carbonate: Prices increased due to sentiment speculation this week. The supply is expected to be in surplus next week, putting pressure on prices. However, "anti - involution" policies may drive up sentiment [16] Group 3: Summary by Metals Copper - Market Concerns: There are concerns about the S232 investigation results, and the NYMEX - LME price spread has widened again [1] - Inventory Situation: By May, over 450,000 tons of electrolytic copper were attracted to the US, causing significant drops in LME and domestic inventories [1] - Price Movement: As LME inventory dropped below 100,000 tons and cancelled warrants soared, copper price volatility rebounded, and the LME cash - 3M spread widened [1] Aluminum - Supply and Demand: Supply increased slightly from January to May, and in July, demand is expected to weaken seasonally. The market is expected to be balanced [1] - Inventory Outlook: In July, supply and demand are expected to be balanced, and attention should be paid to long - term spreads and domestic - overseas reverse arbitrage opportunities in a low - inventory situation [1] Zinc - Price Trend: Zinc prices oscillated upwards this week due to high macro - sentiment [2] - Supply Side: Domestic TC increased by 200 yuan/ton, and imported TC rose by 10 dollars/dry ton.

Domestic inventory oscillates, and overseas consumption continues to drive down LME inventory [11] - Strategy: Long - positions can be cautiously held in the short term, and attention should be paid to short - selling opportunities after the maintenance period in the long - term [11] Industrial Silicon - Production Changes: Hoshine Silicon Industry in Xinjiang significantly reduced production, while production in Yunnan slightly increased, and Sichuan's production remained stable [14] - Supply - Demand Balance: Due to significant production cuts by leading enterprises, the supply - demand balance has shifted to inventory reduction, and prices are expected to oscillate strongly in the short term [14] - Long - Term Outlook: In the long - term, prices will be mainly based on the cash - flow cost of leading enterprises, and attention should be paid to cost reduction due to green - electricity subsidies and falling thermal - power prices [14] Lithium Carbonate - Price Movement: Prices increased due to sentiment speculation this week [16] - Supply and Demand: Supply is expected to be in surplus next week, with downstream demand remaining weak. Some smelters have cut production, and high - cost capacities are being cleared [16] - Price Outlook: The supply surplus will lead to inventory accumulation, putting pressure on prices, but "anti - involution" policies may drive up sentiment [16]
