1. Report Industry Investment Ratings No information about industry investment ratings is provided in the reports. 2. Core Views Lithium Carbonate - The recent market sentiment is stable, and the market is mainly in a state of shock. However, there is a lack of actual positive news, and the short - term fundamentals still face pressure. In June, due to the boost in processing output and the increase in lithium extraction from some spodumene, the balance may be in surplus. The short - term market is expected to operate in a weak range, but the profit - to - risk ratio of short - selling is weakening, and the main contract is expected to operate between 56,000 - 62,000 yuan [1]. Nickel - Recently, the macro situation is temporarily stable, but the sentiment in the spot market is low. The cost support for refined nickel has slightly weakened, and the medium - term supply remains loose, restricting the upside space. The short - term fundamentals change little, and the market is expected to adjust through weak - range shock, with the main contract referring to 118,000 - 124,000 yuan [2]. Stainless Steel - The fundamentals remain weak. The ore end provides some price support, the negotiation range of nickel - iron prices has moved down, the stainless - steel production remains high, and the demand is weak with slow inventory reduction. In the short - term, there is still pressure on the fundamentals due to the supply - demand contradiction. The market is expected to operate weakly, with the main contract operating between 12,400 - 13,000 yuan [5]. Tin - The supply - side recovery is slow. In the short - term, tin prices are expected to be strong and fluctuate. However, considering the pessimistic demand outlook, it is advisable to short at around 260,000 - 265,000 yuan based on the inflection points of inventory and import data [7]. Aluminum - For aluminum, the short - term upper limit is around 20,500 yuan, and the price is expected to be around 20,000 yuan with a fluctuating trend. If the actual demand weakens in the third quarter, the price may find support at 19,000 - 19,500 yuan. For alumina, if the ore - end issues do not worsen, smelters may resume production after profit recovery, and the inventory is expected to gradually increase [8]. Zinc - In the long - term, zinc is in a supply - side loosening cycle. If the growth rate of the ore end is lower than expected and the downstream consumption performs better than expected, zinc prices may remain in a high - level shock pattern. In a pessimistic scenario, zinc prices may decline. It is advisable to short at high levels in the long - term, with the main contract focusing on the support at 21,000 - 21,500 yuan [10]. Copper - Under the combination of "strong reality + weak expectation", copper prices do not have a clear and smooth trend. The strong fundamentals limit the downward movement of prices, while the weak macro - expectations restrict the upside space. In the short - term, prices are expected to fluctuate, with the main contract referring to 77,000 - 80,000 yuan [13]. 3.
