1. Report Industry Investment Rating - Not provided in the given content 2. Core View of the Report - The strengthening of tin prices on Tuesday afternoon may be related to smelter production cut expectations, but both macro and fundamental factors have limited impact. Macroscopically, the US retail sales data in July met expectations. Fundamentally, the repeated delay of the full resumption of production in Myanmar's tin mines has been providing obvious support for tin prices and may have a continuous impact. In the short term, tin prices may remain volatile, with a stable macro environment and room for speculation on supply - side topics [3] 3. Summary by Relevant Catalogs 3.1 Tin Price Volatility and Risk Management - The latest closing price of tin is 268,090 yuan/ton, the monthly price range forecast is 245,000 - 263,000 yuan/ton, the current volatility is 14.36%, and the current volatility's historical percentile is 26.1% [2] - For inventory management with high finished - product inventory and fear of price decline, it is recommended to sell 75% of the Shanghai Tin main futures contract at around 275,000 yuan/ton and sell 25% of the SN2510C275000 call option when the volatility is appropriate. For raw material management with low raw material inventory and fear of price increase, it is recommended to buy 50% of the Shanghai Tin main futures contract at around 230,000 yuan/ton and sell 25% of the SN2510P245000 put option when the volatility is appropriate [2] 3.2 Factors Affecting Tin Prices - **Likely Positive Factors**: Sino - US tariff policy easing, the semiconductor sector still being in an expansion cycle, and Myanmar's resumption of production falling short of expectations [4] - **Likely Negative Factors**: Repeated tariff policies, the inflow of Myanmar's tin ore into China, and the semiconductor sector's expansion slowing down and gradually moving from an expansion cycle to a contraction cycle [5] 3.3 Tin Futures and Spot Data - **Futures Data**: The latest prices of Shanghai Tin main, Shanghai Tin continuous one, and Shanghai Tin continuous three are 268,090 yuan/ton, 268,320 yuan/ton, and 268,290 yuan/ton respectively, with no daily change.

Group 1: Investment Rating - No investment rating for the industry is provided in the report [1] Group 2: Core View - The report believes that the 7.9 - magnitude earthquake in Myanmar on March 28, although the epicenter is some distance from the main tin - mining areas, is likely to delay the resumption of production in the tin mines.
