Report's Industry Investment Rating - No relevant content provided Core Views of the Report - The main contract price of rebar rose 0.06% after hitting a high and falling back, with increasing volume and open interest. Given the weak demand, stable supply, and weakening commodity sentiment, rebar prices are expected to face pressure and fluctuate. Attention should be paid to steel mill production [5]. - The main contract price of hot-rolled coil oscillated, rising 0.33% with increasing volume and open interest. Although the demand for hot-rolled coil is resilient and the fundamentals are stable, the supply is at a high level and there are concerns about demand. If demand weakens, industrial contradictions may accumulate, and prices may face pressure. In the short term, prices will maintain an oscillating trend, and attention should be paid to demand performance [5]. - The main contract price of iron ore oscillated weakly, falling 0.49% with increasing volume and decreasing open interest. Despite positive commodity sentiment and lingering bullish factors, the supply of iron ore is high while demand is weakly stable. The fundamentals are weak, and the upward driving force is not strong. Ore prices will oscillate at a high level, and there is a risk of prices weakening if the trading logic switches to the industrial side. Attention should be paid to steel mill restocking [5].

Report Summary 1. Report Industry Investment Rating No information provided in the report. 2. Core View of the Report - The steel price in the futures market continued to rise today, while the spot steel trading volume was generally average. The basis slightly shrunk, with a small amount of spot-futures purchases and mainly low-price transactions. - Last week, the production of the five major steel products increased, and the molten iron output continued to rise due to the recovery of profit levels. The total steel inventory started to accumulate, but the hot-rolled coil inventory continued to decline, with the inventory shifting from the factory warehouse to the social warehouse, and the overall rebar inventory accumulated. - Affected by the season, the apparent demand for building materials further weakened, and the funds available to downstream construction sites decreased. The demand for hot-rolled coils slightly declined, but there was a replenishment demand in the manufacturing industry before the Spring Festival. The steel export performance in January remained strong. - On the raw material side, the coal mine inventory decreased. Driven by market news, the commodity market recently experienced a sharp rise, which led to an increase in steel prices. The structural shortage of PB fines has not been resolved, and the first quarter is also the traditional off-season for iron ore shipments. Steel mills have a rigid demand for replenishment, providing cost support. - Recently, the continuous resumption of molten iron production has also limited the further rise of steel prices. In the short term, the steel price will maintain a slightly bullish and volatile trend, but the upside space is limited. [6] 3.

Report Industry Investment Ratings - No industry investment ratings are provided in the reports. Core Views Steel Industry - The spot demand for steel is weak, and prices have fully priced in the weak demand. Before the holiday, focus on the impact of policies on the demand expectation of steel. In December, steel prices fluctuated with the rhythm of raw material prices and maintained a sideways trend. Steel production cuts are significant, with limited downward driving force, but the weak demand expectation for the May contract restricts the upside space for prices. The upside elasticity depends on changes in the raw material supply side. Overall, it is expected to fluctuate within a range in January. The reference range for the May contract of rebar is 3050 - 3250 yuan, and for hot-rolled coils, it is 3200 - 3350 yuan [1]. Iron Ore Industry - The fundamental pattern of iron ore is shifting towards a situation of both weak supply and demand. The price ceiling is constrained by high inventories, while the downside is supported by the expectation of steel mills' restocking. In the future, iron ore will gradually transition from a state of loose supply - demand to one of weak supply - demand. During the off - season, it is necessary to focus on macro - sentiment and policy expectations. It is expected that iron ore prices will fluctuate widely in the short term [4]. Coke and Coking Coal Industry - For coke, the supply adjustment lags behind coking coal, and coking profits are under pressure, but the start - up rate is rising. The demand side sees an increase in iron - making water production and a rebound in steel prices at low levels. In terms of inventory, ports and steel mills are accumulating inventory, while coking plants are reducing inventory, and the overall inventory is slightly increasing at a medium level. For coking coal, the supply side has a slight increase in daily production after the new year, and imports are recovering. The demand side has a stable increase in iron - making water production, and the restocking demand is warming up. The overall inventory is also slightly increasing at a medium level. In terms of strategies, it is recommended to go long on dips and pay attention to the strategy of going long on coking coal and short on coke [6]. Ferrosilicon and Ferromanganese Industry - For ferrosilicon, the supply - demand contradiction has been alleviated, and there is support on the demand side. In the short term, focus on macro, policy expectations, and cost - side changes. It is expected to fluctuate within the range of 5500 - 6200. For ferromanganese, it is in a state of self - supply surplus but overall balance of manganese elements. Manganese ore provides price support, and there is also support from off - season demand. Follow - up attention should be paid to the reduction in ferromanganese production and the restocking expectations of steel mills for raw materials during the year - end winter storage. It is expected to fluctuate widely, and the recommended strategy is to operate within the range of 5800 - 6300 [7].
