1. Report's Industry Investment Rating - Not provided in the given content 2. Core Viewpoints of the Report - The overall performance of the black metal market is mixed, with different trends and characteristics in each sub - sector. The market is affected by both macro and industrial factors, and the strategies for different varieties vary [2][4] 3. Summary by Relevant Catalogs Steel - The price of steel is in a state of stable fluctuation, and the driving force is not clear. The market is in a situation of both weak supply and demand. The de - stocking pressure of plates is prominent. After January, iron - water production may stop falling and stabilize, and there will be some appropriate replenishment behavior in the industry. Unilateral trading can be treated with an oscillatory mindset, and the hot - rolled coil futures - spot positive spread can still be rolled [2][4] Ferrosilicon and Silicomanganese (Double Silicon) - The double - silicon market shows a situation of weak reality and strong expectations. The demand has weakened significantly, and it is difficult to improve in the short term. The supply is still high, and the pressure of over - supply in the medium term remains. Although the cost support of silicomanganese is strengthening, the price may fall under pressure in the future. Industrial customers can sell short for hedging at high prices, and investment customers can mainly engage in reverse spreads [4] Coking Coal and Coke - The spot market of coke has an increasing expectation of the fourth round of price cuts, and the coking coal auction has mixed results with a high non - sale rate. The futures market is in an oscillatory state. The steel is still in a pattern of weak supply and demand, which is unfavorable to furnace materials. After the basis repair of the futures market, it is oscillating. It is recommended to wait and see for the time being, and industrial customers can consider purchasing some cost - effective spot goods [4] Iron Ore - The iron - water production shows signs of stabilizing. The port inventory of iron ore will continue to rise, and the price has an obvious upward pressure. Considering the steel mill's maintenance plan and seasonal factors, the iron - water production is expected to stabilize at the end of the month and rise in January. The steel mills will replenish the inventory before resuming production, so the price fluctuation range is limited, and it is recommended to wait and see [4] 4.

Report Industry Investment Rating - No relevant content provided Core Viewpoints - In the short term, the shock correction of the precious metal market may continue due to some long - profit - taking funds leaving the market after the previous strong rally driven by interest - rate cut expectations. In the long term, platinum prices may maintain strong resilience supported by the Fed's interest - rate cut expectations, structural supply - demand deficits, the continuous progress of "platinum replacing palladium", and long - term demand expectations in the hydrogen economy. Palladium demand faces significant downward pressure during the "platinum replacing palladium" process in the gasoline purification catalyst field, and the palladium market is shifting from supply shortage to surplus. However, the bullish sentiment driven by interest - rate cut expectations may support the price, and the subsequent catch - up rally of palladium prices is expected to continue [2].

1. Report Industry Investment Rating No relevant content provided. 2. Report's Core View - Overall, the finished steel products are supported by raw material costs at the lower end but constrained by inventory at the upper end, expected to trade in a range. Attention should be paid to the de - stocking speed of steel and downstream consumption, with the risk of negative feedback due to the decline in the profitability rate of steel enterprises [3]. - Iron ore prices will continue to be weak in the short term. Macroeconomic data in the US and China are weakening, and overseas risk events are reducing market drivers. Fundamentally, supply remains high, port inventories are accumulating, and demand is weak [20]. - Recently, downstream coke and steel mills have been replenishing stocks, and the inventory structure of coking coal has improved. However, steel mill profits are damaged, and the demand for coking coal and coke has peaked seasonally. In the medium - to - long term, policies restricting coking coal supply and winter storage may affect prices [30]. - Ferroalloys are expected to trade in a range as they return to the fundamentals of high inventory and weak demand after the macro - sentiment fades, but are supported by costs [45]. - Soda ash prices are restricted by high inventory but supported by costs. There is a weakening expectation for its rigid demand due to the cold - repair expectation of glass [54]. - Glass sales have weakened recently, and the spot market is under pressure. There is a small expected decline in supply. The 01 contract may decline towards the delivery date, but there is cost support and policy expectation in the long - term [80]. 3.
