1. Report Industry Investment Rating No relevant content provided. 2. Core Views of the Report - Nickel: Under the fundamental logic, it fluctuates in a narrow range, and the long - term logic is under pressure. However, there are frequent events in Indonesia, so be vigilant against the risk of news - driven stimulation [4]. - Stainless steel: The pressure at the real - end still needs to be continuously alleviated, and the steel price fluctuates [5]. - Industrial silicon: Pay attention to the resumption rhythm of upstream factories [34]. - Polysilicon: There will be more event disturbances next week. The main idea is to go long on dips [35]. - Lithium carbonate: Supply is weak while demand is strong, and the price is strengthening [56]. 3. Summaries According to Related Catalogs Nickel - Fundamentals: The marginal operation of the fundamentals is relatively stable. The global refined nickel's visible inventory shows a gentle increase, dragging down the upper limit of nickel prices. The long - term low - cost supply increment may change the cost curve pattern. In the short - term and the second half of the year, the nickel price valuation may be at the window boundary of the ferronickel conversion path. The inventory at the ferronickel link has slightly decreased, slightly boosting the upper limit of the nickel price, but the amplitude is limited. The overall decline of the ore price is relatively mild, and the support has weakened slightly, but it is still difficult for the price to fall sharply. The hype of nickel ore contradictions may decrease, limiting the elasticity of nickel prices [4]. - Market News Impact: Indonesia may crack down on illegal mining, change the RKAB approval cycle, and re - evaluate the nickel ore HPM formula. These events increase the risk of short - selling at low levels and add uncertainty to the nickel price [4]. - Inventory Changes: China's refined nickel social inventory increased by 1,963 tons to 41,286 tons. LME nickel inventory decreased by 570 tons to 211,662 tons [6][7]. Stainless Steel - Fundamentals: The pressure at the real - end still needs to be continuously alleviated. The long - side logic focuses on the decline of inventory at a high level, the reduction of factory inventory pressure in July, and the potential reduction in supply due to policy tightening. The short - side logic comes from the actual supply - demand situation, where the alleviation of pressure needs to be continuous, and the supply elasticity may limit the upside [5]. - Inventory and Production: Social inventory has declined slightly for five consecutive weeks, and the factory inventory pressure in July has decreased. The stainless steel production in August is 3.25 million tons, with a marginal increase. The production in Indonesia in August is 420,000 tons [5]. Industrial Silicon - Price Trend: The industrial silicon futures fluctuated this week, and the spot price increased. The futures price first rose, then fell, and then rose again, influenced by other varieties and macro - sentiment. The spot prices in Xinjiang and Inner Mongolia increased [30]. - Supply - Demand Fundamentals: On the supply side, the weekly industry inventory decreased slightly. Factories in the southwest and northwest regions had some resumptions, but the rhythm was slow. On the demand side, the short - term demand of downstream industries increased marginally, with the polysilicon and organic silicon sectors supporting consumption [31][32]. - Market Outlook: Pay attention to the resumption rhythm of upstream factories. Before a large - scale resumption, the futures price may follow the coking coal futures, but the long - term fundamental direction is bearish. It is recommended to short at high levels and take profits at low levels [34]. Polysilicon - Price Trend: The polysilicon futures fluctuated widely this week, showing a relatively strong trend overall. The spot market had some transactions, but the price did not show obvious improvement [30]. - Supply - Demand Fundamentals: The short - term weekly production remained at a high level, and the upstream inventory increased. The demand from the silicon wafer side improved, and the production in August increased slightly compared with July [32][33]. - Market Outlook: There will be more event disturbances next week. The main idea is to go long on dips. The spot market's signing is approaching the end, and the terminal demand may decrease in September. It is recommended to take profit on the PS2511 - PS2512 inter - period positive spread and maintain the inter - period reverse spread idea [35]. Lithium Carbonate - Price Trend: The lithium carbonate futures price increased significantly, and the spot price also rose. The SMM basis and the spread between contracts changed accordingly [54]. - Supply - Demand Fundamentals: On the supply side, production in Jiangxi and Qinghai was affected, and there were concerns about future production. On the demand side, the downstream production demand in August improved significantly. The social inventory decreased slightly, and the number of futures warrants increased [55]. - Market Outlook: Due to supply disturbances, the lithium price is expected to remain strong for about a month. If the downstream demand in September strengthens, the price will continue to be strong. The futures main contract price is expected to range from 85,000 to 95,000 yuan/ton [56][57].
