Report Industry Investment Rating No relevant content provided. Core View of the Report - After the holiday, industrial silicon and polysilicon showed a weak and volatile trend. For industrial silicon, the policy's impact on the market was limited, and the post - holiday inventory reduction pressure on silicon factories was significant. It is recommended to adopt a wait - and - see approach or conduct light - position short - term operations, and pay attention to the actual implementation of production - cut policies in the southwest region. For polysilicon, the market has fully priced in the policy expectations, and investors are advised to be vigilant against post - holiday correction risks, manage positions, and consider shorting at high prices [2].

1. Report Industry Investment Rating - Not provided in the content 2. Core Views of the Report - **Copper**: The Shanghai copper price increased with higher trading volume last night, and the main contract price broke through the high point in March this year, followed by intraday volatile adjustment. Since Freeport announced a copper mine production cut on September 24th, the copper price has shown a significant increase with higher trading volume, attracting rapid attention from capital and showing strong upward momentum. As China is about to enter the National Day and Mid - Autumn Festival holiday, attention should be paid to overseas market volatility risks [4]. - **Aluminum**: The Shanghai aluminum price fluctuated downward today, with a continuous decline in open interest. Last week, affected by the sharp rise in copper prices, the aluminum price stabilized and rebounded, but the overall rebound was weak. Before the domestic holiday, there were signs of inventory reduction in electrolytic aluminum, providing support for the aluminum price. With a loose macro - environment and a marginal improvement in the supply - demand balance during the peak industrial season, there was an obvious outflow of funds before the holiday. Attention should be paid to the industrial demand situation after the holiday [5]. - **Nickel**: The Shanghai nickel price fluctuated downward today, with a slight decline in open interest. The sector - wide effect of the non - ferrous metals sector driven by copper prices has faded, and the nickel price has dropped back to the level at the beginning of last week. At the industrial level, the long - term oversupply of nickel elements continues to suppress the nickel price. In the short term, the slowdown in the accumulation of nickel ore at ports and the reduction of nickel inventory on the Shanghai Futures Exchange provide support for the nickel price. Continuous attention should be paid to the technical support at the 121,000 yuan mark [6]. 3. Summary by Relevant Catalogs 3.1 Industry Dynamics - **Copper**: In September, the Manufacturing Purchasing Managers' Index (PMI) was 49.8%, up 0.4 percentage points from the previous month, indicating a continued improvement in the manufacturing industry's prosperity level.

The high copper price and the short price - fixing period for downstream customers near the contract roll - over jointly suppressed new orders [8]. - **Nickel**: On September 30th, the price of SMM1 electrolytic nickel was in the range of 121,000 - 123,900 yuan/ton, with an average price of 122,450 yuan/ton, a rise of 450 yuan/ton from the previous trading day.

Report Industry Investment Rating No relevant information provided. Core Views - **Copper**: The copper price fluctuated downward today, with the main contract price breaking below the 80,000 mark and the trading volume slightly decreasing. On the macro - level, the domestic market was weak, with both commodities and stock indices showing a downward trend. On the industrial level, the sharp decline in copper price and pre - holiday restocking demand are expected to increase industrial restocking willingness, which will support the copper price.
