Report Industry Investment Rating - Not provided Core Viewpoint of the Report - Iron ore fundamentals show that supply-side new shipments are gradually decreasing, demand is slightly recovering, and although port inventories are still increasing, they are gradually shifting to downstream steel mills. With the futures contract in a back structure and positive basis, along with the recent general rise in commodity price sentiment, the futures and spot markets form a certain resonance. In the short term, there may be some corrections, but overall, it still shows a gradually strengthening trend in a volatile pattern [4] Summary by Relevant Catalogs Market行情态势回顾 - The main iron ore futures contract fell to 813 yuan/ton, a decrease of 15 yuan/ton (-1.81%) from the previous trading day's closing price, with a trading volume of 443,000 lots, an open interest of 637,000 lots (a reduction of 29,000 lots), and a settled capital of 11.388 billion yuan. The price faced pressure near the previous high of 840 and pulled back [1] - Spot prices of mainstream port varieties declined slightly. The PB powder at Qingdao Port dropped 3 to 829 yuan/ton, the Super Special powder dropped 3 to 707 yuan/ton, and the main swap contract was at 107.9 (-1.1) US dollars/ton [1] - The PB powder at Qingdao Port was converted to a futures price of 860.7 yuan/ton, with a basis of 47.7 yuan/ton (the basis widened). The spread between iron ore contracts 1 - 5 was 45 yuan, and the spread between contracts 5 - 9 was 21 yuan. The iron ore futures contracts showed a back structure and positive basis. Although there was a short - term weak correction, the overall trend continued to strengthen gradually in a volatile manner [1] Fundamental Analysis - At the end of the year, overseas mine shipments decreased significantly month - on - month. Shipments from Australia, Brazil, and non - mainstream regions all weakened. Although the current arrival volume increased month - on - month, it is expected that the previous high shipments will still support high arrival volumes. There are expected disturbances on the supply side [2] - On the demand side, hot metal production recovered month - on - month as blast furnaces resumed production after maintenance. The profitability rate of steel mills slightly recovered, and inventory replenishment gradually started but at a slow pace. There is still an expectation of blast furnace复产 in January. After the sharp rise in futures and spot prices, port trading volume decreased significantly month - on - month [2] - In terms of inventory, port inventories continued to accumulate, and the number of congested ships increased slightly. The inventory pressure is still building up. Steel mill inventories increased to some extent but are still significantly lower than historical levels, and the release of inventory replenishment demand is still slow [2] Macro - level Analysis - Domestically, policy expectations for the first quarter of 2026 are rising. The manufacturing PMI rebounded in December, with both supply and demand improving marginally. The national subsidy policy for 2026 has been released, with some optimizations compared to 2025. The National Development and Reform Commission has organized and issued the list of "two major" construction projects and the central budget investment plan for the early batch of 2026, totaling about 295 billion yuan, and is accelerating the allocation and use of various funds. At the same time, the National Development and Reform Commission has recently approved or approved multiple major infrastructure projects with a total investment of over 400 billion yuan. Coupled with the 500 billion yuan of new policy - based financial instrument funds not fully disbursed in October, the investment side is expected to gradually stabilize in the first quarter [3] - Overseas, Trump may announce the nomination for the new chairman of the Federal Reserve in January. Currently, Hassett is still the most popular candidate, and the interest rate cut path may be faster in the next one to two years [3]

Group 1: Report Industry Investment Rating - There is no information about the report industry investment rating in the provided content. Group 2: Core Viewpoints of the Report - For cotton, the recent significant increase in Zhengzhou cotton futures is mainly driven by the expected reduction in domestic supply in 2026 under policy guidance, and the tight expectation of commercial inventory in the middle and late stages of the year due to stable consumption. However, the cotton yarn market is relatively calm, with limited price increases and poor new - order feedback. The downstream weaving industry has inventory - reduction pressure and is not actively replenishing stocks. The price increase space of cotton is restricted, and it may adjust next week, with limited downside space and support near the 20 - day moving average [1]. - For sugar, as of December 31, 2025, the cumulative sugar production in Yunnan in the 2025/26 sugar - making season was 392,300 tons, a year - on - year increase of 65,400 tons, and the cumulative sugar sales were 281,400 tons, a year - on - year increase of 14,300 tons. The domestic production and sales data basically met market expectations. The international sugar market is calm, and the ICE raw sugar futures price is range - bound. The Indian sugar production is progressing smoothly, but the current price limits its export willingness. The international sugar price is expected to be range - bound in the short term [1]. - The basis between sugar futures and spot has basically been repaired, and the valuation of far - month contracts has also been somewhat repaired. The near - month contracts still face large supply pressure, with weak short - term upward momentum. The large price difference between domestic and international markets may attract more imports, and it may be advisable to buy on dips near the out - of - quota import cost [2]. Group 3: Summary by Related Topics Cotton - The core drivers of the recent significant increase in Zhengzhou cotton futures are the expected reduction in domestic supply in 2026 under policy guidance and the tight expectation of commercial inventory in the middle and late stages of the year due to stable consumption [1]. - The cotton yarn market is calm, with spinning enterprises slightly increasing prices, but new orders from downstream are not positive, and the actual price increase is limited. The downstream weaving industry has inventory - reduction pressure and is not actively replenishing stocks at the end of the year [1]. - The price increase space of cotton is restricted due to the ineffective transmission of upstream price increases to the downstream. It may adjust next week, with limited downside space and support near the 20 - day moving average [1]. Sugar - As of December 31, 2025, the cumulative sugar production in Yunnan in the 2025/26 sugar - making season was 392,300 tons, a year - on - year increase of 65,400 tons, and the cumulative sugar sales were 281,400 tons, a year - on - year increase of 14,300 tons. The domestic production and sales data basically met market expectations [1]. - The international sugar market is calm, the ICE raw sugar futures price is range - bound, the Indian sugar production is progressing smoothly, but the current price limits its export willingness. The international sugar price is expected to be range - bound in the short term [1]. - The basis between sugar futures and spot has basically been repaired, and the valuation of far - month contracts has also been somewhat repaired. The near - month contracts still face large supply pressure, with weak short - term upward momentum. The large price difference between domestic and international markets may attract more imports, and it may be advisable to buy on dips near the out - of - quota import cost [2].

Report Summary - **Report Industry Investment Rating**: Short-term shock is strong [1] - **Core View**: Recently, glass production lines have successively undergone cold repairs, and the short-term supply contraction has improved the phased supply-demand structure. Coupled with the positive market sentiment, the short-term price may maintain a strong shock. It is advisable to buy on dips in the short term. Follow-up attention should be paid to changes in macro policies and the cold repair of production lines [4] Market Review - **Futures Market**: The glass main contract opened low and moved high, strengthening during the day. The three tracks of the 120-minute Bollinger Bands opened upwards, indicating a short-term continuation of the strong shock signal. The intraday pressure was near the previous high, and the support was near today's low. The trading volume decreased by 248,000 lots compared to yesterday, and the open interest increased by 67,492 lots compared to yesterday. The intraday high was 1171, the low was 1136, and the closing price was 1163, up 30 yuan/ton (2.65%) from yesterday's settlement price [1] - **Spot Market**: The overall production and sales were good. Except for the stable prices in the northwest region, enterprises in other regions raised prices. In North China, the market transaction was good, and manufacturers' psychology of holding prices gradually emerged. In East China, downstream demand replenishment was the main factor, and prices were temporarily stable. In Central China, the transaction was okay, and individual manufacturers in Hubei raised prices. In South China, downstream procurement was appropriate, and the center of gravity moved up [1] - **Basis**: The spot price in North China was 1020, and the basis was -143 yuan/ton [1] Fundamental Data - **Supply**: As of January 8, the daily average output of national float glass was 150,100 tons, a decrease of 0.96% compared to the 1st. The national float glass output was 1.0592 million tons, a decrease of 1.32% month-on-month and 3.9% year-on-year. The average industry start-up rate was 71.96%, a decrease of 1.08% month-on-month; the average capacity utilization rate was 75.63%, a decrease of 1.03% month-on-month. The design capacity of the first line in Chenzhou of Hunan Qibin Photovoltaic Technology Co., Ltd. was 1000 tons/day, and it was expected to be water-cooled and repaired today. The design capacity of Yunnan Diankai Energy-saving Technology Co., Ltd. was 520 tons/day, and it stopped feeding last night, and the output is expected to further shrink [2] - **Inventory**: The total inventory of national float glass sample enterprises was 55.518 million weight boxes, a decrease of 1.348 million weight boxes month-on-month, a decrease of 2.37% month-on-month and an increase of 27.04% year-on-year. The inventory days were 24.1 days, a decrease of 1.5 days compared to the previous period. At present, the overall inventory of glass enterprises is showing a downward trend. Most regions are driven by sales policies, the market sentiment has improved, and the production capacity has been reduced, which has boosted the transfer of enterprise inventory to the middle and lower reaches, and there is still a downward expectation in the future [2] - **Demand**: The average order days of national deep-processing sample enterprises was 8.6 days, a decrease of 10.7% month-on-month and 16.1% year-on-year. At present, engineering orders are gradually ending, and the executable days of orders are decreasing, currently concentrated in 10-15 days. Home improvement and other types are still mainly low-value scattered orders [2][3] Main Logic Summary - Supply-side production lines using natural gas as fuel have long-term losses, and those using coal and petroleum coke as fuel are also in a loss state, accelerating the clearance of some enterprises' production capacity. Six glass production lines were water-cooled and repaired before New Year's Day, and three more production lines were cold-repaired this week, further shrinking the supply. However, real estate development investment and capital availability both continued to decline year-on-year, and completion and new construction were weak, with no improvement in real estate demand [4]

1. Report Industry Investment Rating No information provided 2. Core Viewpoints - The pure benzene market shows a state of strong supply and weak demand, with significant upward pressure and should be treated weakly [3] - The styrene market is in the off - season demand in the first quarter. Although it may be boosted by the short - term rebound sentiment of commodities, the demand pressure is still obvious, and the industry should appropriately participate in hedging [4] 3. Summary by Relevant Catalogs Fundamental Analysis - As of December 29, the commercial inventory of pure benzene in Jiangsu ports was 300,000 tons, a month - on - month increase of 9.89% and a year - on - year increase of 56.09%. From December 22 - 28, the estimated arrival was about 39,500 tons and the提货 was about 12,500 tons. During the period, the inventory in 3 warehouses increased and 4 remained stable [1] - As of January 5, 2026, the total inventory of styrene in Jiangsu ports was 132,300 tons, a decrease of 4.68% from the previous period. The commercial inventory was 77,300 tons, a decrease of 7.20% from the previous period. According to past industry rules, there is a high possibility of seasonal inventory accumulation from January to March [1] Macroeconomic Analysis - Trump and his advisors are planning a large - scale plan to dominate the Venezuelan oil industry in the coming years, aiming to push the oil price down to $50 per barrel [2] - On January 8, 2026, the People's Bank of China will conduct a 1.1 trillion - yuan outright reverse repurchase operation with a term of 3 months [2] Futures and Spot Market Analysis - Pure benzene fluctuated slightly during the day, with significant upward pressure and a state of strong supply and weak demand [3] - Styrene fluctuated slightly, and attention should be paid to the pressure near the 40 - day moving average on the weekly line. Affected by the short - term rebound sentiment of commodities, it may be boosted to some extent, but the demand pressure is still obvious [3][4]

Report Industry Investment Rating - No information provided Core Viewpoints of the Report - The futures price dropped 2.15% intraday, with support at the 60-day moving average on the daily chart. There is pressure due to short - term inventory accumulation and general downstream demand, but imports may slow in January, and there is a high possibility of an inventory inflection point in the first quarter. Attention can be paid to buying opportunities after the price pull - back. The key to whether the inventory can enter the destocking cycle in the first quarter lies in the restart time of Iranian plants after gas restrictions [3] Summary by Relevant Catalogs Fundamental Analysis - As of January 7, 2026, China's methanol port inventory totaled 1.5372 million tons, an increase of 4.08 tons from the previous period. The inventory in East China increased by 57,200 tons, while that in South China decreased by 16,400 tons. This week, port inventory continued to accumulate, mainly in Zhejiang, with 227,100 tons of visible foreign vessel unloading. Jiangsu's mainstream storage areas along the Yangtze River had stable pick - up, but inland delivery led to weak shipments at riverside warehouses. In Zhejiang, with concentrated foreign vessel arrivals and stable demand, inventory increased significantly. South China's port inventory decreased slightly. In Guangdong, with a small amount of imports and domestic vessels replenishing and reduced pick - up due to holidays, inventory changed little. In Fujian, with no vessel arrivals and downstream rigid demand consumption, inventory decreased [1] Macroeconomic Analysis - According to the Wall Street Journal, Trump and his advisors are planning a large - scale plan to dominate Venezuela's oil industry in the coming years. Trump believes this can push oil prices down to his preferred level of $50 per barrel. - On January 8, 2026, the People's Bank of China will conduct 1.1 trillion yuan of outright reverse repurchase operations with a term of 3 months (90 days) through fixed - quantity, interest - rate tender, and multiple - price winning bid methods [2] Futures and Spot Market Analysis - The futures price dropped 2.15% intraday, with support at the 60 - day moving average on the daily chart. Short - term inventory accumulation and general downstream demand create pressure. However, imports may slow in January, and there is a high possibility of an inventory inflection point in the first quarter. Attention can be paid to buying opportunities after the price pull - back. The key to whether the inventory can enter the destocking cycle in the first quarter lies in the restart time of Iranian plants after gas restrictions [3]

Report Industry Investment Rating - The short - term rating for the soda ash industry is fluctuating and bullish [1] Core View of the Report - The supply of soda ash is increasing and demand is weakening, which may intensify the supply - demand contradiction. However, in the short term, boosted by macro news and the sharp rise in coal prices, the price may maintain a fluctuating and bullish trend. It is advisable to buy on dips in the short term. Follow - up attention should be paid to downstream demand, macro policies, and market sentiment changes [5] Summary by Relevant Catalogs Market行情回顾 - **Futures Market**: The main soda ash contract opened lower and moved lower during the day, showing a short - term fluctuating and bullish signal. The upper pressure is near the 60 - week moving average, and the support is near the 40 - day moving average. The trading volume decreased by 156,000 lots compared with the previous day, and the open interest increased by 131,000 lots. The intraday high was 1271, the low was 1222, and the closing price was 1239, up 2 yuan/ton or 0.16% from the previous settlement price [1] - **Spot Market**: The spot market rose slightly. Enterprise equipment was generally stable with minor adjustments. The output of Boyuan Yingen increased, and industrial supply remained at a high level. Downstream procurement sentiment was average, mostly replenishing on - demand, with low - price transactions being the main form [1] - **Basis**: The spot price of heavy soda ash in North China was 1250, and the basis was 11 yuan/ton [1] Fundamental Data - **Supply**: As of January 8, domestic soda ash production was 753,600 tons, a month - on - month increase of 56,500 tons or 8.11%. Light soda ash production was 349,100 tons, a month - on - month increase of 23,000 tons; heavy soda ash production was 404,500 tons, a month - on - month increase of 33,500 tons. The comprehensive capacity utilization rate was 84.39%, up 4.43% from the previous week. Among them, the ammonia - soda process capacity utilization rate was 90.41%, a month - on - month increase of 11.20%; the co - production process capacity utilization rate was 74.11%, a month - on - month increase of 1.33%. The overall capacity utilization rate of 15 enterprises with an annual capacity of one million tons or more was 88.15%, a month - on - month increase of 2.24% [2] - **Inventory**: The total inventory of domestic soda ash manufacturers was 1.5727 million tons, an increase of 64,300 tons or 4.26% compared with Monday. Among them, light soda ash was 836,500 tons, a month - on - month increase of 40,800 tons; heavy soda ash was 736,200 tons, a month - on - month increase of 23,500 tons. Compared with last Wednesday, it increased by 164,400 tons or 11.67%.

The downstream demand for soda ash was average, mainly consuming inventory and purchasing at low prices. Light soda ash was relatively stable. At the end of last month, some glass production lines were shut down for cold repair, and the rigid demand for heavy soda ash weakened [3][4] - **Profit**: According to Longzhong Information statistics, the theoretical profit (double - ton) of the co - production method was - 40 yuan/ton, a month - on - month decrease of 12.68%. The theoretical profit of the ammonia - soda process was - 57.85 yuan/ton, a month - on - month increase of 39.65%. During the week, the price of raw material rock salt was stable, and the price of thermal coal increased, leading to an increase in costs [4] Main Logic Summary - Currently, the soda ash production has decreased, but the overall operating rate is relatively high. With the gradual release of new production capacity, the overall output remains at a high level. Before New Year's Day, 6 glass production lines were shut down for cold repair, and this week, another 3 production lines were shut down, further weakening the rigid demand for soda ash and continuously increasing inventory. However, there is some short - term support under continuous losses and positive macro - sentiment [5]
