Report Industry Investment Ratings No relevant information provided. Core Views of the Reports Industrial Silicon - Industrial silicon spot prices are stable, and futures prices are oscillating. It is expected to maintain a weak supply - demand situation in December, with prices fluctuating in the range of 8000 - 9000 yuan/ton, and attention should be paid to the support at 8000 yuan/ton and coal price changes [1]. Polysilicon - Spot prices are stable, and the main contract has risen. Although new delivery brands are beneficial for increasing deliverable volume and warehouse receipts, considering weak demand and a large decline in production, polysilicon futures may still oscillate at a high level, and the spot is still under pressure [2]. Aluminum Alloy - The casting aluminum alloy market is oscillating strongly in the game between strong cost support and weak demand. It is expected to maintain a narrow - range high - level oscillation in the short term, with the main contract reference range of 20700 - 21400 yuan/ton [3]. Aluminum - Alumina is expected to maintain a bottom - oscillation, with the main contract reference range moving down to 2400 - 2700 yuan/ton. Aluminum is expected to run strongly in the short term, with the main contract of Shanghai Aluminum oscillating in the range of 21700 - 22400 yuan/ton [4]. Tin - Market sentiment is positive, and the fundamentals are strong. It is expected that tin prices will maintain a strong trend throughout the year, and a bullish view on tin prices is maintained [6]. Zinc - With the decline of TC, the supply pressure is relieved, and the short - term price has limited downward space. The export of refined zinc drives the spot to tighten, boosting domestic zinc prices. The short - term Shanghai zinc price trend may be stronger than that of London zinc, and the main contract should focus on the support at 23000 - 23200 [8]. Copper - In the short term, the imbalance of global copper supply and inventory drives copper prices to rise rapidly, and price fluctuations may intensify. In the long term, the supply - demand contradiction of copper still exists, supporting the gradual upward movement of the bottom center of copper prices [10]. Nickel - Macro factors are temporarily stable. After the valuation repair of nickel prices, the price driving force weakens. In the medium term, the loose fundamentals restrict the upward space of prices. It is expected to oscillate in a range in the short term, with the main contract reference range of 116000 - 120000 [13]. Stainless Steel - Macro factors are temporarily stable, the supply pressure eases slightly, but the demand in the off - season is weak, and inventory reduction is not smooth. It is expected to oscillate and adjust in the short term, with the main contract operating range of 12400 - 12800 [15]. Lithium Carbonate - The lithium carbonate market is running strongly. Although the fundamentals have not changed much, the market is affected by news of slower - than - expected upstream resumption of production. In the short term, it may maintain a strong oscillation under the drive of capital sentiment [18].

Industry Investment Ratings No information about industry investment ratings is provided in the reports. Core Views Oils and Fats - Palm oil may face downward pressure if it fails to hold above 4,100 ringgit, with support at 4,000 ringgit. In China, there is a risk of downward break - out for palm oil futures, with support around 8,000 yuan. - For soybean oil, the EIA has lowered its forecasts for renewable diesel production in 2025 and 2026. However, Fed rate cuts and the rebound of BMD palm oil support CBOT soybean oil. In China, the spot basis is shifting to the May contract, and the factory's soybean oil inventory is high but may decrease in Q1 2026. The basis of the January contract may decline slightly, while that of the May contract is supported [1]. Meal and Grains - U.S. soybeans lack trading highlights, with slow - growing Chinese demand and strong South American crop expectations. The market is not optimistic about medium - to - long - term U.S. soybean prices. - In China, the soybean meal supply is loose, but the market is speculating on longer soybean clearance times. The 1 - 5 positive spread has strengthened, and attention should be paid to its performance [2]. Livestock (Pigs) - There is some reluctance to sell in the market, and the spot price is stable. The southern pickling demand is increasing, but there are uncertainties in the December - January market due to potential pandemic impacts and secondary fattening. The overall supply pressure is large, and the price is hard to improve. The futures market is struggling to rise and has fallen in the past two days. Monitor the pandemic situation [4]. Sugar - ICE raw sugar futures are under pressure below 15 cents per pound. India's sugar production in Maharashtra is increasing. The overall raw sugar price is bearish. In China, the sugar - making process in Guangxi and Yunnan is accelerating, new sugar supply is increasing, and the market is weak. Domestic sugar prices are expected to fluctuate weakly [8][9]. Corn and Corn Starch - The price of corn in the northern port is rising slightly due to insufficient supply, while prices in the Northeast and North China are stable or weak. The demand side is cautious, with deep - processing and feed enterprises mainly making rigid purchases. The corn futures market is expected to fluctuate, and attention should be paid to the continuity of supply [10]. Eggs - The supply of eggs is relatively sufficient, with a slight decrease in the number of laying hens in November but still at a high level. The market is moving goods at a normal pace, but demand is weak. Egg prices are expected to fluctuate weakly with limited downside [14]. Cotton - ICE cotton futures fell due to weak U.S. export demand. In China, Zhengzhou cotton futures face increasing hedging pressure, and the spot basis is weakening, putting downward pressure on prices. However, the downstream demand for cotton is strong, limiting the downside. Attention should be paid to the 14,000 resistance level [16].

Core Views of the Reports Oils and Fats - Palm oil: Malaysian palm oil futures may face downward pressure if they cannot hold above 4,100 ringgit, with support at 4,000 ringgit. In China, Dalian palm oil futures could break down due to bearish fundamentals, with support around 8,000 yuan. - Soybean oil: The US EIA has lowered its forecasts for renewable diesel production in 2025 and 2026. However, the Fed's potential rate cuts and the rebound of BMD palm oil support CBOT soybean oil. In China, the spot basis is shifting to the May contract, and the first - quarter soybean imports are expected to decrease, which may reduce factory soybean oil inventories [1]. Meals - US soybeans: Lack trading highlights, with slow - growing Chinese demand and high crushing demand. South American new crops are progressing well with strong harvest expectations. The market is not optimistic about medium - to - long - term US soybean prices. - Domestic soybean meal: The loose supply pattern continues, but the market is speculating on longer soybean customs clearance times, and the 1 - 5 positive spread has strengthened. The spot pressure remains, but the future supply is expected to tighten [2]. Pigs - The market has some reluctance to sell, and the spot price is stable.
