From end of October,the price of silicon metal went up with other raw materials ,most of silicon factories will be out of market from early December gradually when Southeast China is in a period of lack of water,in that period there is high hydro-power rate.Factories all knew the situation and held the stocks ,they want to sell them at a higher price in future days.As a result,there were not enough stocks in market,so the price increased day by day,till now the price is higher about 700 Yuan RMB than price in middle of October, and it seems also on the up way.
