Group 1: Report Industry Investment Ratings - No industry investment ratings are provided in the report. Group 2: Core Views - For copper, the inventory depletion rate may continue to slow down, and attention should be paid to the consumption inflection point. The weekend's Sino-US negotiation rumors may boost market sentiment. For the month spread, the current inter - month positive spread has shown a large space, and subsequent upward momentum requires substantial shortages or a decline in absolute prices. [1] - For aluminum, supply has increased slightly, and the demand expectation in May does not decline significantly. There is still a supply - demand gap. It is recommended to wait and see on the absolute price, take profit on the aluminum internal - external reverse spread, and continue to hold the inter - month positive spread if the absolute price drops. [1] - For zinc, the zinc price center has moved down slightly in a volatile manner. It is in a situation of strong current reality and weak expectation. It is recommended to short at high prices, continue to hold the internal - external positive spread, and pay attention to the inter - month reverse spread opportunity after mid - May. [2] - For nickel, the short - term fundamental situation is weak, and there is still instability in tariffs and continuous disturbances at the mine end. Attention should be paid to Indonesia's tariff policy on China and the opportunity for the nickel - stainless steel price ratio to shrink. [4] - For stainless steel, the overall fundamentals remain weak, and under the influence of tariffs, the steel mill's profit is under pressure. The unilateral price is expected to be under pressure in the short term, and the reverse spread can be rolled over and continued to be held. [7] - For lead, the lead price is expected to oscillate between 16,700 and 16,900 next week, and the supply in May is expected to decrease cyclically. [8] - For tin, in the short term, the domestic raw material supply is still disturbed, and the fundamentals are expected to remain tight in the first half of the year. It is recommended to wait and see in the short term and pay attention to short - selling opportunities in the medium - long term. [8] - For industrial silicon, the short - term supply - demand double - reduction pattern is obvious, and the price is expected to oscillate at the bottom in the medium - long term. [10] - For lithium carbonate, in the short - term, the downstream demand enters a small peak season, but the demand improvement is less than expected. In the medium - long term, the price is expected to oscillate weakly.
