1. Report Industry Investment Rating - Not provided in the content 2. Core View of the Report - For silicon manganese, the supply - demand contradiction is yet to accumulate, the cost side strongly supports the price, but new warehouse receipts in the short term will suppress the upward price limit. It is recommended to participate mainly through short - term long positions, with the main contract reference range being [5750, 6000] [4][5] - For silicon iron, the supply - demand contradiction is not prominent, the warehouse receipts are on a high - level downward trend but still high in absolute value, suppressing the upward price limit. It is expected to move within a range following coal prices in the short term, and it is recommended to participate mainly through short - term long positions, with the main contract reference range being [5550, 5700] [49] 3.
