1. Report Industry Investment Rating No information provided in the content. 2. Core Viewpoints of the Report - Copper prices may fluctuate strongly in the short - term, with the Fed's interest - rate cut expectations and anti - involution policy expectations providing support, while the expected increase in supply after the implementation of US copper tariffs poses an upper - bound pressure [1]. - Aluminum prices may fluctuate, supported by the relatively low domestic aluminum ingot inventory and the resilience of external demand, but pressured by weak downstream consumption and volatile trade situations [3]. - Lead prices are expected to show a weak and volatile trend due to the narrowing supply and high downstream inventory levels [4]. - Zinc prices are difficult to fall in the short - term despite the long - term oversupply situation, supported by the low LME warehouse receipts [6]. - Tin prices are expected to decline as the supply is expected to recover significantly in the fourth quarter while the demand remains weak [7]. - Nickel prices may have a callback pressure as the short - term improvement in downstream demand is limited, despite a small rebound [9]. - Carbonate lithium prices are affected by the news of mine shutdowns, with frequent emotional fluctuations in the market. Traders are advised to be cautious [11]. - Alumina is expected to maintain an oversupply pattern, and it is recommended to short at high prices [14]. - Stainless steel prices are expected to show a strong and volatile trend due to the tight market supply [16]. - Cast aluminum alloy prices have limited upward space due to the off - season of downstream demand and the large basis between futures and spot prices, despite cost support [18]. 3.
