多空因素均衡，锌价调整空间有限

Group 1: Investment Rating - No investment rating information provided in the report. Group 2: Core Viewpoints - Last week, the main contract price of Shanghai zinc futures bottomed out and rebounded. The macro - situation is centered around the Fed's October interest - rate cut expectation, and the market is waiting for the non - farm payrolls report. The improvement in demand has led to inventory reduction, and the low overseas inventory and strong structure support the zinc price. However, the resumption of production in domestic refineries and new capacity input will keep the supply high, limiting the upward elasticity of zinc prices. Overall, the long - and short - term forces are balanced, and the continuous adjustment space of zinc prices is limited [3][4][12]. Group 3: Summary by Directory 1.
