In contrast, polysilicon rose by 3.45%, driven by positive news regarding a new polysilicon storage platform [2][3] - The energy and chemical sectors were negatively impacted by a more than 2% drop in international oil prices, leading to declines across the board on December 9 [1][6] Polysilicon Market - Polysilicon prices surged due to market speculation about a new storage platform established by Beijing Guanghe Qiancheng Technology Co., which is believed to be a platform for integrating polysilicon production capacity. This speculation has bolstered bullish sentiment in the polysilicon market [3] - Despite the positive sentiment, analysts caution that the polysilicon market is still facing a dual reduction in supply and demand, with current market conditions relying heavily on major companies to support prices [3] Swine Futures - Swine futures continued their upward trend, with the main contract rising by 1.55% and reaching a three-week high. Expectations of increased demand for processed pork due to upcoming cold weather and transportation cost increases contributed to this rise [4] - Analysts noted that the pressure on swine supply has decreased, and the market is stabilizing as demand strengthens, particularly with the arrival of the snow season [4] Industrial Silicon and Aluminum - Industrial silicon prices fell sharply, influenced by weak demand and stable supply conditions. The overall supply of industrial silicon is steady due to increased production from northern manufacturers, despite low operating rates in southern regions [5] - Aluminum oxide prices hit a new low since listing at 2533 yuan/ton, primarily due to excess supply and limited production cuts. The overall operating capacity of aluminum oxide remains high, indicating continued downward pressure on prices [6]
