Some metals are affected by factors such as supply - demand relationships, inventory changes, and policy expectations, and their prices are expected to fluctuate in the short - to - medium term [2][3][4] Summary by Metal Copper - On Friday, Shanghai copper showed a positive line oscillation, regaining part of the intraday gains.

The market was regarded as an oscillation, and risk control should be done well [9] Industrial Silicon - The industrial silicon futures rose slightly. The current market supply - demand contradiction was not prominent, and the price was expected to maintain an oscillation [10] Polysilicon - The polysilicon futures continued to oscillate. The current spot price corresponded to the lower edge of the oscillation range, and the upper space still depended on the implementation progress of the production capacity management policy. The operation idea was to go long on dips [11]
