1. Report Industry Investment Ratings - There is no information about industry investment ratings in the provided reports. 2. Core Views Steel Industry - Black metals rose strongly, with coking coal hitting the daily limit and steel futures rising 80 - 90 yuan/ton, the largest daily increase since August. Steel continued to cut production and reduce inventory. Rebar maintained a large supply - demand gap and good de - stocking, while hot - rolled coil de - stocking was still slow. Apparent demand declined seasonally, and demand was weak. Production cuts supported steel prices, and raw materials were expected to drive steel prices up within a range. Rebar was expected to fluctuate in the 3000 - 3200 range, and hot - rolled coil in the 3150 - 3350 range [1]. Iron Ore Industry - The iron ore main contract rose significantly due to news - driven factors and a strong commodity market influenced by macro news. Spot prices followed the increase. Supply: global iron ore shipments declined this period, and future focus was on Southern Hemisphere weather. Demand: hot metal production increased slightly, and January's hot metal production was expected to rise slightly. The steel mill profit rate improved, and the hot - rolled coil inventory problem improved. Inventory: iron ore inventory was at a high level, while steel mill inventory remained low. Future inventory was expected to continue to accumulate. Iron ore was expected to shift from loose supply - demand to weak supply - demand, and prices were expected to fluctuate strongly in a high - level range, with a short - term reference range of 770 - 840 [4]. Coke and Coking Coal Industry - Coke futures rose strongly. The fourth round of coke price cuts was implemented on January 1st. The coke market was weakly stable. Supply: coke production declined due to pressure on coking profits. Demand: steel mills increased maintenance due to losses, hot metal production declined, and steel prices fluctuated at a low level. Inventory: overall inventory increased slightly. Coking coal futures rose strongly, with the main contract hitting the daily limit. Supply: coal mine production increased slightly, but sales were poor, and inventory accumulated. Import coal inventory continued to accumulate, and Mongolian coal prices fluctuated downward. Demand: steel mill maintenance decreased, hot metal production was stable with a slight increase, and coking profits declined. Inventory: overall inventory increased slightly. Policy - related information needed verification. For both, unilateral trading was advised to wait for policy verification, and the arbitrage strategy was to go long on coking coal and short on coke [6]. Ferrosilicon and Ferromanganese Industry - Ferrosilicon: The main contract continued to rise, driven by macro news and cost - side coal news. Supply: production increased slightly last week and was expected to continue to grow. Demand: hot metal production was expected to increase slightly in January, and the demand from the metal iron and magnesium industries supported ferrosilicon. Cost: power prices were stable or slightly decreased, and cost differences among regions widened. The supply - demand contradiction was alleviated, and prices were expected to fluctuate strongly in the 5600 - 6300 range. Ferromanganese: Prices fluctuated upward, affected by macro news. The news of increased export tariffs on South African manganese ore was false. Supply: production was basically flat, and the reduction amplitude continued to narrow. Demand: hot metal production was expected to increase slightly, supporting ferromanganese demand. Cost: manganese ore prices were stable, providing strong support. The market was in a state of self - supply surplus but overall balance of manganese elements. Prices were expected to fluctuate widely, with a reference range of 5800 - 6400 [7]. 3.
