On January 9, Lihuayi Weiyuan Chemical Co., Ltd. raised the ex-factory settlement price of acetone by 100 yuan to 4,400 yuan per ton, effective from January 9. PriceSeek Analysis: Acetone, Bull-Bear Score: 1 Reason: Lihuayi Weiyuan Chemical Co., Ltd. increased the ex-factory settlement price of acetone by 100 yuan per ton to 4,400 yuan per ton, reflecting tight supply or stronger demand, which is expected to directly boost the spot price of acetone. This adjustment is considered a general positive, as the price increase is significant but not at a level that would cause a major stimulus, possibly influenced by seasonal demand or cost-driven factors. MIBK, Bull-Bear Score: 1 Reason: As acetone is a primary raw material for MIBK, the rise in acetone prices will increase the production cost of MIBK, indirectly pushing up its spot price. This event is regarded as a general positive, as the cost transmission effect is evident, though it does not directly involve changes in supply and demand. Attention should be paid to the downstream market's response.
