Report Summary 1. Report Industry Investment Rating The document does not mention the industry investment rating. 2. Core Viewpoints - Today, all stock indices fluctuated and rose. The total market turnover of the stock market was 1865 billion yuan, an increase of 116.3 billion yuan from the previous day's turnover. The positive policy expectations in 2026 are gradually fermenting, driving the market risk appetite to gradually recover. The willingness of medium - and long - term funds to allocate has increased, providing strong support for the stock indices. However, in the short term, the trading volume of the stock market is still at a relatively low level, indicating that there are still differences in investors' risk preferences, and most of them are waiting and watching. In the medium and long term, the positive policy expectations and the trend of capital inflow remain favorable, and the support for the stock indices is strong. In general, the stock indices will maintain a range - bound oscillation in the short term. [3] - In terms of options, the position - to - call ratio (PCR) and implied volatility are neutral.

Group 1: Report Industry Investment Rating - No information provided Group 2: Core Viewpoints - Today, Treasury bond futures fluctuated and pulled back. Currently, there is pressure above and support below Treasury bond futures, with weak driving forces, so they are expected to maintain a fluctuating consolidation. On the one hand, the problem of insufficient effective domestic demand still exists, and the monetary policy environment next year is expected to be loose, with interest rate cuts and reserve requirement ratio cuts still anticipated. Coupled with the weak implied interest rate cut expectations in the current market interest rates, Treasury bond futures have strong support. On the other hand, in the short term, macroeconomic data shows strong resilience, and the urgency for a comprehensive interest rate cut in the short term is not high. Coupled with fewer uncertainties and disturbances in the recent internal and external environment, Treasury bond futures lack upward drivers. In general, Treasury bond futures will mainly fluctuate and consolidate in the short term [4] Group 3: Summary by Relevant Catalogs Industry News and Related Charts - On December 22, the People's Bank of China authorized the National Interbank Funding Center to announce the latest LPR quotation. The 1-year LPR was reported at 3.0%, the same as last month; the 5-year and above LPR was reported at 3.5%, also the same as last month. Thus, the LPR quotations for both tenors have remained unchanged for 7 consecutive months. On December 22, the central bank conducted 6.73 billion yuan of 7-day reverse repurchase operations today, with an operating interest rate of 1.40%, the same as before [6]

Group 1: Report Industry Investment Rating - No relevant content Group 2: Core Viewpoints of the Report - Copper: After the Bank of Japan's interest rate hike, the macro environment improved, and copper prices rose with increasing positions. Last week, copper prices first declined and then rebounded, with the trading volume increasing as prices rose. High copper prices have suppressed consumption, leading to a continuous weakening of the basis and monthly spreads, with a clear pattern of near - term weakness and long - term strength in futures prices. The 2026 copper concentrate long - term processing fee benchmark was set at $0/ton and $0/lb. In the short term, macro factors are driving copper prices up, with strong upward momentum, and the industry is following passively. Keep an eye on the pressure at the $12,000 mark for LME copper and the RMB 95,000 mark for SHFE copper. [5] - Aluminum: After the Bank of Japan's interest rate hike, the macro environment improved, and aluminum prices rose with increasing positions. Last week, aluminum prices first declined and then rebounded, similar to copper. After the interest rate hike on Friday, the market sentiment improved, and aluminum prices increased with positions, recovering the losses of the week. As aluminum prices rise, downstream sentiment is turning more cautious. The substitution of aluminum for copper in the home appliance industry is expected to increase, giving a strong consumption outlook for aluminum, which may also make long - term aluminum prices stronger than near - term ones. Technically, keep an eye on the high - level pressure in early December. [6] Group 3: Summary of Each Section According to the Table of Contents 1 Macro Factors - After the Bank of Japan's interest rate hike last Friday, it was a relief for the US dollar, and short - term market liquidity increased. The US dollar index and copper prices rebounded simultaneously. [10] 2 Copper 2.1 Quantity and Price Trends - Last week, copper prices first declined and then rebounded, and the trading volume increased as prices rose. High copper prices have suppressed consumption, leading to a continuous weakening of the basis and monthly spreads, with a clear pattern of near - term weakness and long - term strength in futures prices. [5] 2.2 Copper Ore Shortage - Last week, copper ore port inventories continued to rise from a low level and were approaching the same level as previous years. On December 19, Mysteel's copper ore port inventory was 680,000 tons, a weekly increase of 16,000 tons. The short - term increase in port inventories has slowed down, and the overall level is still at a low level compared to previous years. The 2026 copper concentrate long - term processing fee benchmark was set at $0/ton and $0/lb. [25] 2.3 Electrolytic Copper Inventory Accumulation - On December 18, Mysteel's electrolytic copper social inventory was 174,500 tons, a weekly increase of 3,300 tons, and the COMEX + LME inventory was 623,800 tons, a weekly increase of 10,700 tons. Short - term copper price increases have significantly suppressed downstream consumption, leading to an increase in inventories. However, there has been a clear divergence in domestic and overseas inventories since December, which may be due to stronger domestic industrial demand and overseas weakness, or may be digested through exports. [27] 2.4 Downstream Primary Processing - In November, the capacity utilization rate of copper products rebounded month - on - month, indicating that downstream acceptance increased after copper prices reached a high and then declined in November. As copper prices broke through upwards at the end of November, it is expected that downstream sentiment will turn more cautious again, and the capacity utilization rate in December may decline significantly. SMM predicts that the total output of the copper rod industry in December will decrease by 45,000 tons month - on - month to 1 million tons. In terms of the operating rate, the operating rate of electrolytic copper rod enterprises was 65.07%, a month - on - month decrease of 1.58 percentage points and a year - on - year decrease of 7.53 percentage points; the operating rate of recycled copper rod enterprises was 19.61%, a month - on - month decrease of 4.23 percentage points and a year - on - year decrease of 16.73 percentage points. [29] 3 Aluminum 3.1 Quantity and Price Trends - Last week, aluminum prices first declined and then rebounded, similar to copper. After the interest rate hike on Friday, the market sentiment improved, and aluminum prices increased with positions, recovering the losses of the week. As aluminum prices rise, downstream sentiment is turning more cautious, and the spot discounts of LME aluminum and SHFE aluminum remain weak. [6] 3.2 Upstream Industry Chain - On December 12, the aluminum ore port inventory was 26.08 million tons, a decrease of 355,400 tons from the previous week and an increase of 8.69 million tons compared to the same period in 2024. Last week, alumina showed signs of stabilizing after fluctuations but remained weak overall. The improvement in the macro environment has stabilized it, but the weak industrial fundamentals have led to its weak performance. The strong aluminum prices and weak alumina prices have widened the profit margins of electrolytic aluminum plants. [44][45] 3.3 Slowdown in Electrolytic Aluminum Inventory Reduction - On December 18, Mysteel's electrolytic aluminum social inventory was 561,000 tons, a decrease of 18,000 tons from the previous week; the overseas electrolytic aluminum inventory was 526,200 tons, an increase of 700 tons from the previous week. Global electrolytic aluminum inventories are in a state of slow reduction at a low level, which provides strong industrial support for aluminum prices. [48] 3.4 Downstream Primary Processing - Last week, the processing fee of aluminum rods increased, indicating a recovery in downstream demand and a strong willingness of the downstream industry to replenish inventories at a low level. On December 18, the aluminum rod inventory was 100,700 tons, an increase of 14,200 tons from the previous week. The slight increase in aluminum rod inventory last week corresponded to the increase in processing fees, as aluminum rod production enterprises replenished inventories at a low price. [52][54] 4 Conclusion - Copper: Last week, copper prices first declined and then rebounded, and the trading volume increased as prices rose. In the short term, macro factors are driving copper prices up, with strong upward momentum, and the industry is following passively. Keep an eye on the pressure at the $12,000 mark for LME copper and the RMB 95,000 mark for SHFE copper. - Aluminum: Last week, aluminum prices first declined and then rebounded, similar to copper. The substitution of aluminum for copper in the home appliance industry is expected to increase, giving a strong consumption outlook for aluminum, which may also make long - term aluminum prices stronger than near - term ones. Technically, keep an eye on the high - level pressure in early December. [58]
