Report Industry Investment Rating - Not provided in the given content Core Viewpoints - On December 15, equity index futures and CGB futures declined; most commodities rose, with platinum and palladium leading the gains [2][4][11][13] - The PBoC, MOF, SASAC and other departments studied and conveyed the spirit of the Central Economic Work Conference [1][3][37][38][39][40][41][42] Summary by Relevant Catalogs 1. China Futures 1.1 Overview - On Dec 15, equity index futures (IC fell by 0.9%, IM fell by 0.8%) and CGB futures (TL fell by 1.0%) declined; most commodities rose, with platinum (up 7.0%, positions +59.7% MoM), palladium (up 4.7%, positions +60.6% MoM) and poly - silicon (up 3.6%, positions +13.0% MoM) leading the gains. The top three decliners were apple (down 3.0%, positions +15.6% MoM), rapeseed oil (down 1.9%, positions +2.2% MoM) and copper (BC) (down 1.5%, positions -16.7% MoM) [11][12][13][14] 1.2 Daily Raise 1.2.1 Poly - Silicon - On Dec 15, poly - silicon rose by 3.6% to 58,030 yuan per ton. A “Poly - Silicon Platform Company” was registered on Dec 9, heating up state reserve purchase expectations. But its fundamentals are weak due to terminal installation pressure. Supply was affected by the southwest dry season in Nov (output 115,000 tons, -14.5% MoM), and is expected to be weak in Dec. Demand is weak due to new energy power price reform and the downstream off - season. Inventory is growing, and warehouse receipts may rebound [17][18][19] 1.2.2 Coking Coal - On Dec 15, coking coal rose by 3.2% to 1,061 yuan per ton. Supply from major domestic producing areas like Shanxi is tight due to production task completion and underground factors, while Mongolian coal customs clearance remains high. Demand: coke output fell slightly, but mid - and downstream purchases increased, slowing upstream inventory accumulation. Recently, prices were weak, but downstream replenishment demand is increasing as the year - end approaches, and futures showed signs of an oversold rebound on Friday night [24][25][26] 1.2.3 Aluminium Oxide - On Dec 15, aluminum oxide rose by 3.0% to 2,537 yuan per ton. Market fundamentals are weak, with spot/futures prices falling. After Friday night's rebound, the main contract rebounded over 4% by morning. Key issues are high supply (with minor short - term capacity fluctuations), rising inventory (due to limited downstream demand growth), and falling costs (weak raw material prices). Loss - driven production cuts are unlikely, and further observation of industrial chain production cuts is needed [31][32][33] 2. China News 2.1 Macro News - PBoC: Continue the prudent and accommodative monetary policy, accelerate financial supply - side structural reform, use tools like RRR cuts and rate reductions, maintain ample liquidity, keep financing costs low, and support the real economy [37][41] - SASAC: Central enterprises should proactively advance major projects, support domestic demand expansion, ensure stable supply and prices of basic products, and resist “involutionary competition” [38][39][41] - MOF: Maintain necessary fiscal deficit, total debt scale and expenditure next year, improve policy precision, use government bonds, and support “two majors” and “two news” initiatives [40][41][42]

1. Report Industry Investment Rating - Not provided in the content 2. Core View of the Report - The alumina market has a weak fundamental situation with high supply, rising inventory, and weak cost support. Although the price has rebounded recently, the upward pressure on the market remains significant. Traders are advised to adjust their strategies according to market changes [3][4] 3. Summary by Relevant Catalogs 3.1 Industry Policy Trends - On December 12, the head of the State - owned Assets Supervision and Administration Commission of the State Council studied the spirit of the Central Economic Work Conference. The conference emphasized that central enterprises should focus on promoting new - quality productivity, strengthen technological innovation, promote industrial upgrading, and avoid "involution - style" competition [2] 3.2 Fundamental Situation - Recently, the market fundamentals have been weak, with futures and spot prices falling. After the call against involution, most low - priced varieties rebounded rapidly on Friday night, with the main alumina contract rebounding by over 4% by the morning [3] - The fundamental contradictions lie in high supply, rising inventory, and weak cost support. Supply has limited reduction due to short - term factors; inventory is rising as demand growth is limited; cost has not formed good support as raw material prices are weak [3] 3.3 Summary and Strategy - Fundamentally, the market is in a loss situation, with high upstream operating capacity and a strong inventory accumulation trend. The spot price is under pressure, but the near - month warehouse receipts are expected to decline [4] - During the previous decline period, strategies such as short - selling at high prices, monthly reverse arbitrage, and selling put options performed well. Currently, traders are advised to shorten the trading period, adjust positions, and convert some short positions to selling call options. If there are significant marginal changes, trading opportunities such as call options and monthly positive arbitrage should be considered [4]

Report Industry Investment Rating - Not provided Core Viewpoints of the Report - On December 15, 2025, platinum and palladium prices soared. The platinum main - contract rose 7.0% to 482.4 yuan/gram, and the palladium main - contract rose 5.82% to 411.8 yuan/gram. The reasons were the market's trading of the potential future interest - rate cuts due to the perceived impairment of the Fed's independence and the tightening of the spot market supply [2]. - In 2026, platinum supply will maintain stable production with a limited increase in overall output, while palladium supply will see a slight increase. Platinum demand will grow, but palladium demand will face a significant decline. There will be a 37.9 - ton gap in platinum supply - demand and a 16.9 - ton surplus in palladium supply - demand [3]. - Long - term bullish view on platinum, with expected price ranges of 1400 - 2400 dollars/ounce for WMEX platinum and 370 - 630 yuan/gram for GFEX platinum. Short - term bullish view on palladium, with expected price ranges of 100 - 2000 dollars/ounce for WMEX palladium and 280 - 520 yuan/gram for GFEX palladium [4]. Summary by Relevant Catalogs Latest Dynamics and Reasons - On December 15, 2025, platinum and palladium prices rose significantly. The platinum main - contract increased by 7.0% to 482.4 yuan/gram, and the palladium main - contract increased by 5.82% to 411.8 yuan/gram [2]. - The reasons were the market's anticipation of future interest - rate cuts due to the potential impairment of the Fed's independence and the tightening of the spot market supply. As the nomination of the new Fed chair approached, the market traded on the risk of the Fed's independence. Trump's statement about Kevin Warsh as a potential candidate and the expected weak non - farm data increased the interest - rate cut expectations, driving up precious - metal prices. Also, the platinum spot market tightened, with the 1 - month lease rate rising to 14.12% as of December 12 [2]. Fundamental Situation Supply - In 2026, with the rise in platinum prices and profit recovery, major producers will maintain stable production, but overall output will be limited due to few new project launches. Global platinum mine and refined production are expected to rise 2.8% and 4.8% to 173.0 tons and 228.2 tons respectively. Global palladium mine and refined production are expected to rise 0.3% and 2.2% to 108.9 tons and 299.4 tons respectively. Short - term supply risks from extreme weather, labor disputes, and power shortages should be watched [3]. Demand - In 2026, the global economic recovery will drive the industrial demand for platinum to continue to pick up. Jewelry demand will also show an upward trend, offsetting the decline in automotive catalyst demand. Platinum price fluctuations and the launch of domestic futures may stimulate global platinum investment. Global platinum demand is expected to grow 0.7% to 266.1 tons. Palladium demand will face significant downward pressure, with an expected decline of 1.7% to 282.4 tons [3]. Supply - Demand Balance - In 2026, there will be a 37.9 - ton gap in global platinum supply - demand and a 16.9 - ton surplus in global palladium supply - demand [3]. Summary and Strategy Platinum - The impairment of the Fed's independence and the expectation of liquidity easing drive up platinum prices. In the long - term, due to high supply concentration, stable demand growth in industrial and investment sectors, and the "interest - rate cut + soft landing" combination, a long - term bullish view is maintained. The expected price range for WMEX platinum is 1400 - 2400 dollars/ounce, and for GFEX platinum is 370 - 630 yuan/gram. It is recommended to buy on dips and consider a long - platinum and short - palladium strategy when the platinum - palladium spread is low [4]. Palladium - The Russian geopolitical issue affects palladium supply. The US investigation into Russian unforged palladium imports has led to a temporary supply shortage in other regions. Palladium demand has significant structural pressure. Although the long - term supply - demand is loosening, the short - term shortage makes the price firm. With the Fed's potential interest - rate cuts, the palladium price has a certain bottom support. The expected price range for WMEX palladium is 100 - 2000 dollars/ounce, and for GFEX palladium is 280 - 520 yuan/gram. Short - term low - buying is also recommended [4].

Report Industry Investment Rating - Not provided Core View of the Report - The tin price may show an oscillating upward trend, with the short - term SHFE tin fluctuating in the range of 305,000 - 400,000 yuan/ton, and it is recommended to focus on the low - buying and long - selling strategy [5] Summary According to Relevant Catalogs Latest Dynamics and Reasons - On December 12, 2025, the tin price soared. By the close, the main contract of SHFE tin rose 4.54% to 833,000 yuan/ton, hitting a new high for the year. Supply disruptions and low inventory in the industrial chain are the main reasons for the strong performance of the tin price [3] - The security situation in eastern Congo has deteriorated recently. As the main tin - producing area, the escalating situation has kept the risk of tin ore supply high, intensifying market concerns. After two years of inventory digestion, the inventory in the entire tin industry chain is at a significantly low level, increasing the supply - demand contradiction and strongly supporting the tin price [3] Fundamental Situation - The supply side remains the core concern of the market. Problems such as financial pressure and blocked explosive transportation have slowed down the resumption of production at the Peruvian tin plant. Indonesia's refined tin supply is affected by RKAB approval and is expected to be restricted in the first quarter of next year. Political instability and poor infrastructure in Africa have continuously restricted tin ore production and exports, and the current risk remains high [4] - As of December 5, the processing fee (TC) for 40% tin concentrate in Yunnan was 12,000 yuan/ton. From January to November 2025, China's cumulative tin ingot production was 182,800 tons, a year - on - year decrease of 2.9%. In November, the daily output was 1,600 tons, a year - on - year decrease of 6.1%. Some smelting enterprises temporarily stopped production due to raw material supply problems, causing a slight decline in tin ingot production in November. The long - term shortage of raw materials has led to the operating rate of most smelting enterprises being below 70% of the production capacity plan for a long time [4] Summary and Strategy - In terms of supply, the continuous tightening of the ore end has led to a shortage of raw materials for smelters, low tin concentrate processing fees, and difficulty in increasing the output of refined products. In terms of demand, the United States is still in the late - cycle stage, and fiscal expansion is expected to have a positive effect on the global economy. The semiconductor industry maintains high growth, and consumption in the photovoltaic and new - energy vehicle sectors continues to rise. Considering the need to rebuild the industrial chain inventory, tin demand will continue to grow [5]
