1. Report Industry Investment Rating No relevant content provided. 2. Core View of the Report - The recent correction in precious metal prices is mainly due to the expectation of a temporary easing of overseas risk events and an over - bought correction in trading, rather than a reversal of the trading logic. The price decline is more of a "correction in the upward trend" than a "trend reversal" based on geopolitical risks, weakening US dollar credit, and the start of the Fed's interest - rate cut cycle. It is recommended to maintain a long - position strategy, focusing on the upcoming Fed interest - rate meeting and considering buying on dips. [2][4] 3.

Group 1: Report Industry Investment Rating - No relevant information provided Group 2: Core View of the Report - The lithium carbonate market is experiencing a phased improvement in fundamentals, but there is selling pressure above. The traditional peak - off - peak season transition may be delayed. Attention should be paid to industrial hedging and supply elasticity release, as well as the quarterly reports of mining companies and the fulfillment of demand expectations [1][3][15] Group 3: Summary of Each Section 1. Fundamental Phased Repair - In the context of the peak production season for lithium - battery downstream industries, the lithium carbonate market has shifted from oversupply to phased supply - demand tightness. Since October, the Guangzhou Futures Exchange lithium carbonate futures index has risen 9.01%, and the average premium of lithium carbonate in the trading market has increased from - 200 yuan to + 150 yuan [3] - On the demand side, energy - storage demand has grown explosively, and the pre - demand effect of new energy vehicles is significant. In Q3 2025, China's energy - storage lithium - battery shipments were about 165GWh, a year - on - year increase of 65%. The full - year shipments are expected to reach 580GWh, with an annual growth rate of over 75%. The domestic sales of new energy vehicles in the first three quarters increased by 24.6% year - on - year, and the lithium carbonate consumption per vehicle increased by about 10 - 15%. The traditional peak - off - peak season transition may be delayed [3] - On the supply side, the growth has slowed, and there is a structural contraction, accelerating inventory depletion. Domestic lithium carbonate production has hit new highs since early September, but the resumption of large lithium - mica mines has not been realized, and the pressure of overseas lithium carbonate imports has eased. The monthly output of lithium - mica - extracted lithium has dropped to 1.1 - 1.2 million tons, only 60% of the monthly peak this year. The total direct import of lithium carbonate in the first three quarters was about 173,000 tons, with a year - on - year increase of only 5.2%. The domestic social inventory of lithium carbonate has continued to decline, and the Guangzhou Futures Exchange lithium carbonate warehouse receipts decreased by 13,000 tons (- 31.2%) in October [4] 2. There is Selling Pressure Above, and Attention Should Be Paid to the Fulfillment of Demand Expectations - Under a neutral forecast, the global lithium supply surplus in 2026 is expected to be about 11%, similar to 2024 and 2025. There is a co - existence of peak - season support and long - term supply looseness in the lithium carbonate market, and market pessimism has not been completely eliminated [15] - There is significant selling pressure on rising lithium prices. From October 20 to October 24, 2025, the lithium carbonate futures positions increased by 106,000 lots, a weekly increase of 15.1%. The net short positions of the top ten seats increased from 146,000 lots to 191,000 lots. The price increase has opened up short - selling opportunities, attracting many holders to hedge, and there is significant selling pressure at the 80,000 - yuan/ton mark [15] - The release of high - cost resources may accelerate. Since July, the lithium - price center has risen, and the supply of high - cost hard - rock mines in Australia, Africa, etc., has steadily increased. In September, China imported 521,000 tons of lithium concentrates, a year - on - year increase of 38.0% and a month - on - month increase of 10.6%. The supply pressure of high - cost hard - rock mines has eased, and the concentrates previously held back by mining companies are gradually being released. Attention should be paid to the quarterly reports of overseas mining companies [16] - Attention should be paid to the fulfillment of consumption expectations. In 2026, the new energy vehicle purchase tax subsidy in China will be adjusted from full exemption to half exemption, and there are different views on the impact on the demand side. In an optimistic scenario, the high - growth trend of lithium - battery demand will continue, while in a pessimistic scenario, the industry may face destocking in the first half of 2026. Currently, the vehicle and energy - storage markets are in a year - end rush period, and subsequent attention should be paid to the capital game around the first - quarter operating expectations of the lithium - battery industry [17]

1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - The long - term logic of steel prices remains unchanged under the gradually loosening macro - environment, but the weak real - demand pattern of steel is difficult to improve significantly in the short term [2]. - For the black sector, the report maintains a non - pessimistic view. It believes that finding callback positions to do rebounds may be more cost - effective than shorting [10]. - For manganese silicon, if the black sector strengthens, pay attention to potential disturbances in the manganese ore end; otherwise, it is expected to follow the black sector's trend. For silicon iron, it is likely to follow the black sector's trend with a low cost - performance for operation [10]. - For industrial silicon, it is expected to move in a short - term consolidation, easily following the commodity environment. For polysilicon, the supply - demand pattern may improve, and the price shows a wide - range shock pattern [13][16]. - For glass, it is expected to continue a weak and narrow - range shock trend. For soda ash, the price is expected to maintain a stable and weak trend [19][21]. 3. Summary According to Related Catalogs Steel **Market Information** - The closing price of the rebar main contract was 3046 yuan/ton, down 25 yuan/ton (- 0.81%) from the previous trading day. The registered warehouse receipts increased by 1437 tons, and the main contract positions increased by 81220 lots. The Tianjin and Shanghai spot prices decreased by 10 yuan/ton and 20 yuan/ton respectively [1]. - The closing price of the hot - rolled coil main contract was 3250 yuan/ton, down 6 yuan/ton (- 0.18%) from the previous trading day. The registered warehouse receipts decreased by 4799 tons, and the main contract positions decreased by 182 lots. The Le Cong and Shanghai spot prices decreased by 0 yuan/ton and 10 yuan/ton respectively [1]. **Strategy Viewpoints** - Macroscopically, the "15th Five - Year Plan" period is crucial. Future development focuses on high - quality development of real estate and population. Fundamentally, rebar shows a neutral performance with both supply and demand increasing and inventory decreasing. Hot - rolled coils have a slight decline in production, rising demand, and marginal inventory reduction but still at a relatively high level [2]. - The steel mill profitability rate has declined significantly, and the molten iron output has dropped significantly, reducing the supply - side pressure marginally. In the short term, the weak real - demand pattern of steel is difficult to improve [2]. Iron Ore **Market Information** - The main contract (I2601) of iron ore closed at 771.00 yuan/ton, with a change of - 0.77% (- 6.00), and the positions increased by 4501 lots to 56.56 million lots. The weighted positions were 95.82 million lots. The spot price of PB powder at Qingdao Port was 778 yuan/wet ton, with a basis of 55.83 yuan/ton and a basis rate of 6.75% [4]. **Strategy Viewpoints** - Supply: The overseas iron ore shipment volume has rebounded, with increases in Australia, Brazil, and FMG's shipments, and a slight increase in non - mainstream countries' shipments. The near - end arrival volume has decreased [5]. - Demand: The average daily molten iron output has dropped below 240,000 tons, affected by weak steel prices, low mill profitability, and environmental protection in Hebei. The contradiction between high molten iron and terminal demand has been realized, and the molten iron output has decreased [5]. - Inventory: Port inventory continues to increase, and mill inventory has a slight increase. Fundamentally, the iron ore demand has weakened, and the port inventory has continued to accumulate, putting pressure on prices [5]. - Macroscopically, pay attention to the "15th Five - Year Plan" details and the results of Sino - US economic and trade consultations, which may improve market sentiment [5]. Manganese Silicon and Silicon Iron **Market Information** - On October 24, the main contract of manganese silicon (SM601) closed down 0.79% at 5772 yuan/ton.

The Tianjin spot price was 5650 yuan/ton, with a basis of 108 yuan/ton [7][8]. **Strategy Viewpoints** - Macroscopically, important meetings have positive statements, but there is no super - expected content. Pay attention to Sino - US economic and trade consultations and the APEC meeting. The black sector's fundamentals have concerns about high supply and low demand, and the mill profitability rate has dropped to 47.62%. There may be a "negative feedback" risk in the short term [9]. - For the black sector, it is not pessimistic. It is more cost - effective to find callback positions to do rebounds. For manganese silicon, pay attention to potential disturbances in the manganese ore end. For silicon iron, it is likely to follow the black sector's trend [9][10]. Industrial Silicon and Polysilicon **Market Information** - Industrial silicon: The main contract (SI2601) closed at 8920 yuan/ton, down 1.55% (- 140).

The weighted positions decreased by 12,056 lots to 231,619 lots. The average spot prices of N - type granular silicon, N - type dense material, and N - type re -投料 were unchanged, with a basis of 675 yuan/ton [15]. **Strategy Viewpoints** - Industrial silicon: Supply pressure persists, with increasing weekly output. Demand support is weakening, and there is no obvious improvement in supply and demand. It is expected to move in a short - term consolidation, following the commodity environment [13][14]. - Polysilicon: Supply pressure may be marginally relieved as some capacities may be overhauled. The downstream start - up rate is expected to be stable. The supply - demand pattern may improve, and the price shows a wide - range shock pattern [16]. Glass and Soda Ash **Market Information** - Glass: The main contract closed at 1092 yuan/ton, down 1.44% (- 16). The weekly inventory of float glass sample enterprises increased by 233,740,000 cases (+ 3.64%).

The top 20 long - position holders increased 6467 lots, and the top 20 short - position holders increased 32,937 lots [20]. **Strategy Viewpoints** - Glass: Entering the end of the traditional peak season, downstream procurement has slowed down, and supply has increased. The supply - demand contradiction is difficult to resolve in the short term. It is expected to continue a weak and narrow - range shock trend [19]. - Soda ash: The industry supply remains high, and demand is weak. The supply - demand pattern is difficult to reverse in the short term, and the price is expected to be stable and weak [21].
