Report Industry Investment Ratings - Copper: The rating is not clearly interpretable from the Chinese - like symbols provided. Analysis indicates potential resistance at integer levels [1]. - Aluminum: The rating is not clearly interpretable. It is expected to be in short - term oscillation with resistance at the 21,000 yuan area [2]. - Alumina: The rating is not clearly interpretable. It is in a weak oscillation, testing the 3000 - yuan support level [2]. - Casting Aluminum Alloy: The rating is not clearly interpretable. It follows the movement of Shanghai Aluminum [2]. - Zinc: The rating is not clearly interpretable. There is a mid - line idea of short - selling on rebounds [3]. - Lead: The rating is not clearly interpretable. In the short - term, it is seen as oscillating [5]. - Nickel and Stainless Steel: The rating is not clearly interpretable. Technically, nickel has a rebound intention, but the fundamental is weak, suggesting looking for short positions [6]. - Tin: The rating is not clearly interpretable. It is recommended to hold previous long positions and wait for profit realization, with caution when chasing up above 275,000 yuan [7]. - Lithium Carbonate: The rating is not clearly interpretable. It is in a relatively strong oscillation [8]. - Industrial Silicon: The rating is not clearly interpretable. There is a risk in going long, with the current focus on the 8300 - yuan/ton support level [9]. - Polysilicon: The rating is not clearly interpretable. It is expected to maintain an oscillating trend [10]. Core View The report analyzes the market conditions of various non - ferrous metals. It takes into account factors such as inventory changes, supply - demand relationships, and policy expectations. Different metals show different trends, including oscillation, potential rebounds, or weakening trends. For example, some metals have clear resistance or support levels, and the market sentiment and trading volume also vary among different metals [1][2][3][5][6][7][8][9][10]. Summary by Metal Copper - On Friday, Shanghai copper increased its positions, and the afternoon session expanded the rebound amplitude. The spot copper price was 79,390 yuan, and the Shanghai copper premium widened to 250 yuan. Attention was paid to the US monthly PCE indicator at night, and the resistance at integer levels was strong [1]. Aluminum, Alumina, and Aluminum Alloy - Shanghai aluminum had a narrow - range fluctuation, with spot discounts remaining in various regions. Downstream开工seasonally increased, and inventory was likely to be low this year. However, the inventory accumulation point was not clear, and it was expected to oscillate in the short - term, with resistance at the 21,000 - yuan area. Casting aluminum alloy followed Shanghai aluminum, with the Baotai spot price at 20,300 yuan. The supply of scrap aluminum was tight, and the expected tax policy adjustment increased enterprise costs, with the potential for the cross - variety price difference between spot and Shanghai aluminum to narrow further. Alumina's operating capacity was at a historical high, with increasing industry inventory and Shanghai Futures Exchange warehouse receipts. Supply surplus was emerging, and the spot index in various regions was declining. It was in a weak oscillation, testing the 3000 - yuan support level, and short - term long positions could be considered if the futures discount widened [2]. Zinc - SMM zinc social inventory rose to 144,500 tons, and LME zinc inventory was as low as 58,000 tons, with the cancelled warrant ratio at 25%. The domestic downstream consumption was in the off - season, and there were concerns about pre - consumption. In September, attention was paid to whether the consumption would be weak during the peak season. The increase in the mine end was being realized, and there was still room to short - sell mine profits on the futures market. The mid - line idea of short - selling on rebounds remained unchanged [3]. Lead - LME lead had high inventory, suppressing the lead price. Factors such as pre - consumption, tariff impact, and lithium substitution for lead led to insufficient expected demand growth and lack of rebound momentum. Due to smelter production cuts and transportation restrictions, SMM lead social inventory decreased to 67,100 tons. The raw material shortage situation remained unchanged, and the cost provided support. The downward adjustment space was limited, and in the short - term, the directional signal was weak, with continuous capital outflows. The consumption expectation was difficult to improve fundamentally, and in September, attention was paid to the implementation of smelter maintenance [5]. Nickel and Stainless Steel - Shanghai nickel rebounded, but the market trading was dull. Traders had a strong intention to support prices, and the premium range of mainstream electrolytic nickel remained at - 100 - 300 yuan/ton this week. Affected by the decline in the futures price, the downstream procurement volume increased this week. Pure nickel inventory decreased by 1000 tons to 41,000 tons, nickel - iron inventory remained at 33,000 tons for nearly a month and a half, and stainless - steel inventory remained unchanged at 934,000 tons, but the overall level was still high. Attention was paid to the end of the de - stocking. Technically, nickel had a rebound intention, but the fundamental was weak, and short positions were to be sought [6]. Tin - Shanghai tin increased its positions and rose sharply. Tin announced maintenance as expected. Overseas A1 semiconductor investment remained prosperous, with low LME tin inventory and high premiums. The domestic spot tin price was raised to 272,900 yuan, with a real - time discount of 350 yuan to the delivery month. Attention was paid to social inventory. Caution was needed when chasing up above 275,000 yuan, and attention was paid to capital changes. The tin price might test 280,000 - 282,000 yuan. Previous long positions were to be held, waiting for profit realization [7]. Lithium Carbonate - The lithium carbonate futures price adjusted downward, and market trading declined. Some miners sold goods when the futures price rose, and there were sporadic auctions. After the futures price dived, there was phased reluctance to sell. Downstream continuously adjusted their psychological price levels, and the replenishment behavior was generally cautious. The total market inventory slightly decreased by 700 tons to 142,000 tons, smelter inventory decreased by 3000 tons to 47,000 tons, downstream inventory increased by nearly 3000 tons to 52,000 tons. After the price dropped rapidly, downstream took the opportunity to buy goods, and trader inventory decreased by 1000 tons to 43,000 tons. The speculation sentiment in the mid - stream decreased, and the transfer of goods was mainly from the upstream to the downstream. The latest Australian ore quotation was 925 US dollars, and the ore - end quotation slightly adjusted downward, matching the lithium price fluctuation. The mid - stream production decreased by 5% week - on - week. During the adjustment of the lithium carbonate futures price, the market focus was on the expectation of the 930 deadline after downstream shutdowns, which was difficult to verify in the short - term, and the fundamental had limited guidance on the price. Overall, it was in a relatively strong oscillation, and risk control was needed [8]. Industrial Silicon - The industrial silicon futures price was approaching the lower limit of the oscillation range. In terms of fundamentals, both supply and demand increased in August, and the restarted production capacity in Xinjiang released output. In September, due to industry self - discipline, the production schedule of polysilicon was expected to decline significantly, and the large - scale production cuts in Sichuan and Yunnan might be postponed until after the dry season in September. It was expected that the supply - demand contradiction of industrial silicon would intensify this month, and the spot price had been continuously adjusting downward recently. The futures market was currently focusing on the 8300 - yuan/ton support level. Next week, the policy expectation of polysilicon might ferment, but the fundamental support was weak, and the risk of going long was to be vigilant [9]. Polysilicon - The polysilicon futures closed up in an oscillating manner at around 49,500 yuan/ton. The weekly inventory data of polysilicon decreased rapidly, and downstream trading volume increased, mainly due to industry self - discipline. The production schedule of polysilicon in September was expected to decline significantly. Next week, the "anti - involution" policy expectation might ferment again, but before more details were disclosed, it was expected to maintain an oscillating trend [10].
