Report Summary 1. Report Industry Investment Rating No investment rating information is provided in the report. 2. Core View The soybean oil futures market experienced a significant decline, with the main contract showing a notable drop and a significant reduction in open interest, indicating a growing sentiment of capital leaving the market. The sudden negative news regarding the US biodiesel policy and the high inventory levels at domestic ports jointly pressured the market. Despite the support from the high premium of the spot market, the fundamental bearish situation remains difficult to change. In the short term, the market lacks effective positive drivers, and it is expected that the futures price will maintain a weak and volatile trend. Attention should be paid to the guidance of the MPOB and USDA reports and the actual performance of pre - holiday stocking demand [10]. 3.
