[SMM SiMn Futures Review: Mine-related News Disturbs Futures Market, Continuing to Hold Up Well] The SM2509 contract opened at 5,660 yuan/mt, fluctuated upward after the morning session, and finally closed at 5,676 yuan/mt, up 0.96%. The daily high was 5,704 yuan/mt, and the low was 5,624 yuan/mt. Trading volume was 266,707 lots, and open interest was 398,460. On the raw material side, affected by news of reduced shipments from overseas mines, miners' reluctance to budge on prices has gradually strengthened, and high-grade manganese oxide ore has seen a slight increase in prices. On the spot side, supported by stronger cost support, SiMn spot prices have slightly increased, and factories' willingness to sell at low prices is relatively weak. Attention should still be paid to the development of mine-related news in the future market.
