1. Report Industry Investment Rating There is no information provided regarding the report's industry investment rating. 2. Core Views of the Report - **Precious Metals**: In the medium - to long - term, central bank gold purchases and growing investment demand will push up the price of precious metals. In the short - term, due to the unclear prospect of a December interest rate cut, the prices will likely continue to fluctuate and adjust, with a possible narrowing of the fluctuation range [3]. - **Copper**: The intraday procurement and sales sentiment has increased, and the spot price has risen while the premium has weakened. The copper price faces pressure at 86,500 - 86,600. Given the weak impact of the unemployment data on the December interest rate cut expectation and the dollar index remaining above 100, the copper price will likely fluctuate around 86,000 [17]. - **Aluminum**: Shanghai aluminum will maintain a moderately strong long - term trend. In the short - term, weak fundamentals and a lower probability of a December interest rate cut have led to profit - taking by previous funds. It will likely consolidate with an overall higher price center. Alumina has seen price - increasing orders due to environmental restrictions and short - covering, but it is still in an oversupply situation. Cast aluminum alloy has strong follow - up characteristics to Shanghai aluminum and strong downside support [37][38]. - **Zinc**: The expectation of an interest rate cut has cooled. In terms of fundamentals, the smelting end is competing for ore, resulting in a significant decline in November TC. The smelting end's willingness to reduce or halt production has increased in November. If demand remains stable, there is a possibility of inventory reduction. Currently, there are large differences between bulls and bears, and the bottom space can be observed at the end of the month [59]. - **Nickel and Stainless Steel**: The price of ferronickel has continued to decline, breaking below 900 and still falling due to weak downstream demand. Under the situation of a significant collapse in costs, the downside space for nickel and stainless steel is greater than the upside space. Stainless steel spot has high shipment pressure, and downstream purchasing willingness is low. Attention should be paid to the demand trend and Indonesian policy support expectations [75]. - **Tin**: Fundamentally, there is some resumption of production in Yunnan, but due to the lower - than - expected resumption of production in Wa State, the import of concentrate has sharply decreased, and supply is weaker than demand. In the short - term, it is difficult to solve the raw material problem on the supply side, and Shanghai tin will maintain a high - level shock, with support expected around 276,000 yuan [88]. - **Lithium Carbonate**: This week, lithium carbonate production and inventory showed the characteristic of "increasing production and reducing inventory", but the inventory reduction process has significantly slowed down. High prices have weakened downstream enterprises' willingness to replenish inventory, suppressing price increases. Technically, the futures price faces a key pressure level of 100,000 yuan, with limited short - term upward momentum and significant callback risks [104]. - **Silicon Industry Chain**: For industrial silicon, considering supply - demand and technical factors, the price has strong downside support and limited downward space. For polysilicon, policy - driven short - term stimulation coexists with a weak fundamental situation, and the price increase is limited due to insufficient demand support [115]. 3. Summaries by Relevant Catalogs Precious Metals - **Price Outlook**: Medium - to long - term upward trend; short - term fluctuation and adjustment with possible range narrowing [3]. - **Price Data**: Various price charts of SHFE and COMEX gold and silver, including price trends, spreads, and relationships with other factors such as the US dollar index and US Treasury real interest rates are presented [4][9][12].
