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.
