Report Summary 1. Report Industry Investment Rating No investment rating information is provided in the report. 2. Report's Core View - The nickel and stainless - steel sectors in the non - ferrous metals industry are affected by multiple factors, with prices showing different trends. The nickel price is expected to oscillate sharply between 135,000 - 150,000 yuan/ton, and the stainless - steel price is expected to fluctuate in the range of 13,400 - 14,500 yuan/ton [1][3][4]. 3. Summary by Related Catalogs Nickel Variety - **Market Analysis** - **Futures**: On January 12, 2026, the main contract of Shanghai nickel opened at 140,000 yuan/ton and closed at 144,200 yuan/ton, up 5.65% from the previous trading day. The trading volume was 1,083,202 (-38,224) lots, and the open interest was 124,148 (+3,553) lots. The price increase was driven by supply contraction expectations, macro - easing, and geopolitical risk premiums, along with the overall rise of non - ferrous and precious metals sectors [1]. - **Nickel Ore**: The nickel ore market was calm with limited resources. Affected by macro factors, the price was strong. Philippine mines were eager to sell at higher prices. In Indonesia, the February 2026 domestic trade base price was expected to rise by 2.8 - 4.9 dollars/wet ton, and the current mainstream premium was +25, with a range of +25 - 26. Factories might push down the premium due to cost pressure [1]. - **Spot**: Jinchuan Group's Shanghai market sales price was 150,600 yuan/ton, up 5,300 yuan/ton from the previous day. Spot trading was average, with strong reluctance to sell low - priced resources. The spot premiums of refined nickel were stable or rising. The previous trading day's Shanghai nickel warehouse receipts were 39,670 (+814) tons, and LME nickel inventory was 284,562 (-228) tons [2]. - **Strategy** - Due to the game between supply contraction expectations and the reality of the off - peak demand season, combined with short - term disturbances from macro sentiment and capital behavior, the price is expected to oscillate sharply between 135,000 - 150,000 yuan/ton. It is recommended to focus on range operations and be cautious when chasing high prices. The strategy for single - side trading is range - based, while there are no strategies for inter - period, inter - variety, spot - futures, or options trading [3]. Stainless - steel Variety - **Market Analysis** - **Futures**: On January 12, 2026, the main contract of stainless steel opened at 13,870 yuan/ton and closed at 13,855 yuan/ton. The trading volume was 256,679 (-44,151) lots, and the open interest was 128,736 (-4,171) lots. Affected by the rise of LME nickel, the night trading session opened high and moved high, and the daily trading session was suppressed by weak demand, with the price gradually falling and oscillating between 13,800 - 13,880 yuan/ton in the afternoon [3]. - **Spot**: The futures price increase drove the spot price up, but downstream buyers were reluctant to buy at high prices, resulting in poor inquiry and trading. The stainless - steel price in Wuxi market was 13,900 (+100) yuan/ton, and in Foshan market was 13,775 (+50) yuan/ton. The 304/2B premium was 115 - 315 yuan/ton. The ex - factory tax - included average price of high - nickel pig iron increased by 10.00 yuan/nickel point to 972.0 yuan/nickel point [3][4]. - **Strategy** - The uncertainty of Indonesian policies has a significant impact on the cost of stainless steel, which will be the main short - term price trend logic. The price is expected to fluctuate in the range of 13,400 - 14,500 yuan/ton. However, the dismal spot trading may suppress price rebounds. The single - side trading strategy is neutral, and there are no strategies for inter - period, inter - variety, spot - futures, or options trading [4].

Report Industry Investment Rating No relevant content provided. Core Viewpoints - Market sentiment is shifting towards risk aversion, with attention on the US December CPI data. The inflation narrative is prominent, and future price recovery in China depends on supply - side policies. There are also geopolitical tensions affecting the market, and investors should pay attention to variables in the margin and liquidity markets [2]. - There is a certain divergence in domestic and foreign economic outlooks. Overseas sentiment has declined since October, while China's exports and new orders remain positive. China's November economic data was under pressure, but the December official manufacturing and non - manufacturing PMIs returned to the expansion zone. The US December economic data also showed mixed signals [3]. - In the commodity market, focus on high - certainty sectors such as non - ferrous metals and precious metals. There are potential opportunities for low - valued commodities to catch up. Pay attention to short - term risks in the new energy sector, the situation in Iran and Venezuela in the energy sector, "anti - involution" space in the chemical sector, and weather and disease factors in the agricultural sector [4]. - The strategy for commodities and stock index futures is to buy on dips for stock index futures, precious metals, and non - ferrous metals [5]. Summaries by Related Catalogs Market Analysis - The Central Economic Work Conference in December emphasized boosting consumption and "anti - involution." The 2026 People's Bank of China work conference focused on promoting high - quality economic development and price recovery. Geopolitical tensions between Iran and Venezuela have intensified, and the US Department of Justice's "criminal investigation" of the Fed chairman has added uncertainty. On January 12, the market was strong, with the three major indices rising over 1%, the Shanghai Composite Index achieving 17 consecutive positive days, and AI - related concepts performing well [2]. Economic Data Comparison - China's November foreign trade showed a recovery, with exports increasing by 5.9% and imports by 1.9% year - on - year. November economic data was under pressure, but the December official manufacturing PMI was 50.1 and the non - manufacturing PMI was 50.2, both better than expected. The US December ISM manufacturing index dropped slightly to 47.9, and the non - farm payrolls were lower than expected, but the market remained hot [3]. Commodity Market - In the non - ferrous metals sector, long - term supply constraints remain, and aluminum and nickel are preferred for rotation. In the energy sector, the US plans to "distribute" Venezuelan oil, and Trump has made threats against Iran. In the chemical sector, the "anti - involution" space of methanol and PTA is worthy of attention. In the agricultural sector, weather and short - term pig diseases should be monitored. In the precious metals sector, there are opportunities to buy on dips. On January 12, many commodity futures had significant price increases, and spot gold and silver reached new highs [4]. Strategy - The strategy for commodities and stock index futures is to buy on dips for stock index futures, precious metals, and non - ferrous metals [5]. To - do List - The market showed a strong upward trend on January 12, with the three major indices rising over 1%, the Shanghai Composite Index achieving 17 consecutive positive days, and over 4100 stocks rising. The US December non - farm payrolls were lower than expected, but the unemployment rate decreased. The US January consumer confidence index reached a four - month high. US oil companies are cautious about the Venezuelan investment plan. Trump has made threats against Iran, and the US has launched a criminal investigation into the Fed chairman. Precious metals and some commodity futures had significant price increases [7].

Report Summary Investment Rating - Unilateral: Cautiously bullish. - Arbitrage: Neutral. [5] Core Viewpoint - With the arrival of imported ores and the continuous opening of the import window, smelters' raw material inventory has slightly increased, leading to a decline in the enthusiasm for purchasing domestic ores. The supply pressure is expected to continue to decrease quarter-on-quarter. Although consumption has entered the traditional off - season, zinc consumption remains relatively strong, and social inventory accumulates slowly. Zinc shows relative resistance to decline under capital disturbances, with low absolute valuation and long - term macro factors remaining bullish. [4] Key Information by Category Important Data - **Spot**: The LME zinc spot premium is -$43.99 per ton. The SMM Shanghai zinc spot price is 24,140 yuan per ton, with a change of 110 yuan from the previous trading day and a premium of 75 yuan per ton. The SMM Guangdong zinc spot price is 24,090 yuan per ton, with a change of 130 yuan and a premium of 25 yuan per ton. The Tianjin zinc spot price is 24,070 yuan per ton, with a change of 110 yuan and a premium of 5 yuan per ton. [1] - **Futures**: On January 12, 2026, the SHFE zinc main contract opened at 24,070 yuan per ton and closed at 24,125 yuan per ton, a change of 245 yuan from the previous trading day. The trading volume was 104,562 lots, and the position was 73,033 lots. The highest price during the day was 24,140 yuan per ton, and the lowest was 23,895 yuan per ton. [2] - **Inventory**: As of January 12, 2026, the total inventory of SMM seven - region zinc ingots was 118,300 tons, a change of - 200 tons from the previous period. The LME zinc inventory was 106,800 tons, a change of - 650 tons from the previous trading day. [3] Market Analysis - With the arrival of imported ores and the continuous opening of the import window, smelters' raw material inventory has slightly increased. The domestic ore TC remains stable, while the imported ore TC continues to decline. The smelter's raw material available days are not high, and the TC is difficult to rise in the short term. The comprehensive smelting profit is difficult to repair, and the output in the first quarter may still fall short of expectations, reducing supply pressure. Consumption has entered the traditional off - season, but zinc consumption remains relatively strong, social inventory accumulates slowly, and the spot premium is maintained. [4] Strategy - **Unilateral**: Cautiously bullish. - **Arbitrage**: Neutral. [5]

Report Summary 1. Report Industry Investment Rating No investment rating information is provided in the report. 2. Core Views - Industrial silicon prices are expected to maintain range - bound oscillations. With supply and demand both decreasing, along with the upward price transmission of coal and the photovoltaic industry chain, price support is evident. The upside potential depends on downstream demand recovery and inventory clearance, while the downside is limited by cost support and production - cut expectations [3]. - The short - term demand for polysilicon is expected to rise due to the cancellation of the photovoltaic VAT export tax - rebate policy. However, the polysilicon market is fundamentally weak, vulnerable to macro - sentiment and policy factors. In the short term, it is advisable to stay on the sidelines, and in the medium - to - long - term, short on rallies [7]. 3. Summary by Related Catalogs Industrial Silicon - **Market Analysis** - On January 12, 2026, the industrial silicon futures price fluctuated upwards. The main contract 2605 opened at 8860 yuan/ton and closed at 8755 yuan/ton, a change of 0.75% from the previous day's settlement. The position of the main contract 2605 was 238,877 lots at the close, and the total number of warehouse receipts on January 11, 2026, was 10,888 lots, a change of 96 lots from the previous day [1]. - The spot price of industrial silicon remained basically stable. According to SMM data, the price of East China oxygen - passing 553 silicon was 9200 - 9300 yuan/ton, 421 silicon was 9500 - 9800 yuan/ton, Xinjiang oxygen - passing 553 price was 8600 - 8800 yuan/ton, and 99 silicon price was 8600 - 8800 yuan/ton. Silicon prices in various regions were flat, and the price of 97 silicon remained stable. As of January 8, the total social inventory of industrial silicon in major regions was 552,000 tons, a decrease of 0.9% from the previous week [1]. - **Consumption End** - The quoted price of silicone DMC was 13,700 - 14,000 yuan/ton. The recent cancellation of the photovoltaic VAT export tax - rebate policy is expected to increase short - term polysilicon demand. The strong export of polysilicon is expected to boost the demand side of industrial silicon, and there is short - term upward space for consumption. The operating rate of aluminum - silicon alloy enterprises decreased slightly, and the silicone industry maintained a peak - shifting emission reduction policy. The downstream demand for aluminum alloys showed marginal weakening, and the subsequent operating rate is expected to be stable with a slight downward trend [2]. - **Strategy** - Industrial silicon prices are expected to maintain range - bound oscillations. - Single - side: Short - term range operation. - No strategies are recommended for inter - period, cross - variety, spot - futures, and options [3]. Polysilicon - **Market Analysis** - On January 12, 2026, the main polysilicon futures contract 2605 fluctuated downwards, opening at 52,350 yuan/ton and closing at 49,995 yuan/ton, a 2.89% change from the previous trading day's closing price. The position of the main contract reached 48,830 lots (50,943 lots the previous trading day), and the trading volume on the day was 42,510 lots. - The spot price of polysilicon remained stable. According to SMM statistics, the price of N - type material was 51.50 - 58.50 yuan/kg, and the price of n - type granular silicon was 50.00 - 58.50 yuan/kg. - Polysilicon factory inventory increased, and silicon wafer inventory increased. The latest statistics showed that polysilicon inventory was 30.20 (a change of - 1.30% month - on - month), silicon wafer inventory was 26.23GW (a 13.11% month - on - month increase), polysilicon weekly output was 23,800 tons (a change of - 0.80% month - on - month), and silicon wafer output was 10.52GW (a 3.34% month - on - month increase) [3]. - **Strategy** - The short - term strategy is to stay on the sidelines, and in the medium - to - long - term, short on rallies. - Single - side: Short - term range operation, and the main contract is expected to remain weakly oscillating. - No strategies are recommended for inter - period, cross - variety, spot - futures, and options [7].

Report Summary 1. Report Industry Investment Rating Not provided in the given content. 2. Core View of the Report - On January 12th, the afternoon closing price of the main asphalt futures contract BU2603 was 3157 yuan/ton, down 8 yuan/ton from the previous settlement price, with a gain of 0.25%. The open interest was 222,525 lots, down 3,135 lots, and the trading volume was 220,926 lots, down 13,052 lots. The spot prices of heavy - traffic asphalt showed mixed trends, and the overall market atmosphere was fair. The current contradictions and drivers in the asphalt market mainly come from the cost side. After pricing in the expected tightening of crude oil supply, the futures market has entered a volatile phase. Due to the escalating situation in South America and the US's intention to strengthen control over Venezuelan resources, the expected tightening of Venezuelan crude oil supply to domestic refineries is being continuously realized. The market is now focusing on the availability of alternative raw materials and their impact on costs. If Venezuelan crude oil that originally flowed to Asia continues to flow to Europe and the US, after the consumption of inventory raw materials (expected to last until March), domestic refineries will need to seek alternative heavy - quality raw materials from the Middle East, Canada, South America, etc., including discounted resources from Russia and Iran, which will make the changes in cost and product yield more complicated and require dynamic tracking. Overall, the cost center of asphalt raw materials may rise compared to before the incident [1]. 3. Strategy Summary - **Single - side Strategy**: Cautiously bullish. Buy the main BU contract on dips, but avoid excessive chasing of rising prices [2]. - **Inter - period Strategy**: Buy the spread of BU2303/2306 on dips (positive spread trading) [2]. - **Inter - commodity Strategy**: None [2]. - **Futures - cash Strategy**: None [2]. - **Options Strategy**: None [2]. 4. Figures and Their Units - **Spot Prices**: Figures 1 - 6 show the spot prices of heavy - traffic asphalt in different regions (Shandong, East China, South China, North China, Southwest, and Northwest), with the unit of yuan/ton [3][5][8][10]. - **Futures Prices**: Figures 7 - 10 show the closing prices of the asphalt futures index, the main contract, the near - month contract, and the near - month spread, with the unit of yuan/ton [3][20][22]. - **Trading Volume and Open Interest**: Figures 11 - 12 show the trading volume and open interest of asphalt futures, with the unit of lots [3][26]. - **Production**: Figures 13 - 18 show the weekly asphalt production in China, the production of independent refineries, and the production in different regions (Shandong, East China, South China, North China), with the unit of 10,000 tons [3][28][30]. - **Consumption**: Figures 19 - 22 show the consumption of asphalt in different fields (road, waterproofing, coking, ship fuel), with the unit of 10,000 tons [3][40][41]. - **Inventory**: Figures 23 - 24 show the refinery inventory and social inventory of asphalt according to Longzhong's data, with the unit of 10,000 tons [3][44].
