1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - Zinc prices are under pressure from above and supported from below, with no clear direction. The short - term is expected to maintain range consolidation. Unilateral strategies should focus on high - selling and low - buying, and arbitrage strategies can consider going long on the Shanghai - London ratio [3][65][66]. - The tight pattern of the zinc ore end is expected to continue until the first quarter of next year. The TC has changed from rising to falling, and the industrial chain profit has shifted from the smelter end to the ore end again. The inventory trends at home and abroad are diverging [2][62][63]. 3.
