1. Report Industry Investment Rating - No relevant information provided 2. Core Viewpoints of the Report - The manganese - silicon industry has low - level operation of the industry's start - up rate, both supply and demand increase, inventory is being destocked, and the supply - demand gap narrows. With cost support from manganese ore and geopolitical disturbances, the futures price is expected to fluctuate with a slight upward trend, but high inventory limits the upside space [2]. - The silicon - iron industry has a slight increase in start - up, a significant recovery in demand, and continuous inventory destocking. With stable cost support and geopolitical disturbances, it is expected to follow the manganese - silicon to fluctuate with a slight upward trend [2]. 3.
