1. Industry Investment Rating - Not provided in the given content 2. Core Viewpoints - The cost support for propylene remains strong, and downstream demand is maintained by rigid needs [1] - On the supply side, the restart of Wanhua Penglai's PDH unit is expected, but the actual supply increase may be slow due to the rising propane price and pressured PDH profits. The supply is expected to increase slightly. On the demand side, downstream rigid demand provides support, but the demand may be limited as propylene prices rise. The main drivers in the future are the trends of crude oil and propane in the cost - end, the maintenance status of major PDH plants, and the downstream demand and production resumption under cost pressure [2] - The strategy suggests a wait - and - see approach for single - side trading. In the short term, due to high geopolitical uncertainties and acceptable supply - demand support, propylene prices may fluctuate and strengthen following the cost side. No strategies are provided for inter - period and cross - variety trading [2] 3.

1. Report Industry Investment Ratings - Steel: Sideways [2] - Iron Ore: Sideways to Bearish [4] - Coking Coal and Coke: Sideways [6] - Thermal Coal: Stable to Slightly Bullish [7] 2. Core Views - The steel market is in a slack season with prices oscillating weakly. The overall contradiction in the steel market is not prominent, but poor building material demand, weak downstream purchasing sentiment, and higher seasonal inventory accumulation are suppressing rebar prices. High inventory is also constraining the price space of hot-rolled coils. Before the holiday, steel inventories continue to rise, and supply-demand pressure increases slightly. With weakening raw material prices, steel prices will maintain a weakly oscillating trend [1]. - The iron ore market sentiment is weak, and prices are oscillating. High prices have led to high non-mainstream shipments, but global shipments are seasonally declining. Daily average hot metal production is stable, and iron ore consumption has slightly increased month-on-month. Port inventories are continuously rising, and as steel mill restocking nears completion, the support for raw material prices is weakening. The supply-demand contradiction in the iron ore market is deepening, and if port liquidity issues are resolved, port supplies could cause a significant supply shock [3]. - The coking coal and coke market is experiencing weak trading, with prices oscillating weakly. As the holiday approaches, more coal mines are announcing shutdowns, leading to a light trading atmosphere, with many auctions failing and prices falling in the coking coal market. After the first round of coke price increases, coke producers' profits have improved, but most steel mills have completed winter restocking, leading to a sharp decline in speculative demand for coke [5]. - The thermal coal market is experiencing weak supply and demand, with prices remaining stable. As the Spring Festival approaches, more private mines in the main production areas are on holiday, leading to a tightening supply. Downstream demand, except for some chemical industries, has shrunk significantly. The market is characterized by low activity, with supply and demand both weak. Import coal prices are rising due to supply uncertainties in Indonesia. Before the holiday, the upside for prices is limited, and they are expected to remain stable to slightly bullish. After the holiday, as coal mine supply resumes and the peak season nears its end, prices may face downward pressure [7]. 3. Summary by Related Catalogs Steel - **Market Analysis**: Yesterday, steel futures prices oscillated downward. On Monday, the rebar inventory in Hangzhou was 79.3 million tons, with an outbound volume of 0.2 million tons, compared to 58.5 million tons and 0.5 million tons respectively in the same period last year. Building material demand is poor, and downstream purchasing sentiment is weak. Seasonal inventory accumulation is slightly higher than last year, suppressing rebar prices. Plate demand is relatively stable, but high inventory is constraining the price space of hot-rolled coils [1]. - **Supply and Demand Logic**: Before the holiday, steel inventories continue to rise, and supply-demand pressure increases slightly. With weakening raw material prices, steel prices will maintain a weakly oscillating trend. Later, attention should be paid to winter restocking and changes in raw material prices [1]. - **Strategy**: Sideways for single - sided trading, no strategies for inter - period, inter - variety, spot - futures, or options trading [2]. Iron Ore - **Market Analysis**: Yesterday, iron ore futures prices oscillated. In the spot market, the prices of mainstream imported iron ore varieties at Tangshan Port fluctuated slightly. Traders' quotes mostly followed the market, and steel mills' purchases were mainly for刚需. The cumulative transaction volume of iron ore at major national ports was 55.5 million tons, a 13.01% month - on - month decrease. The cumulative transaction volume of forward - looking spot iron ore was 69.5 million tons (5 transactions), a 13.93% month - on - month increase (with all transactions from mines) [3]. - **Supply and Demand Logic**: High prices have led to high non - mainstream shipments, but global shipments are seasonally declining. Daily average hot metal production is stable, and iron ore consumption has slightly increased month - on - month. Port inventories are continuously rising, and as steel mill restocking nears completion, the support for raw material prices is weakening. The supply - demand contradiction in the iron ore market is deepening, and if port liquidity issues are resolved, port supplies could cause a significant supply shock. Later, attention should be paid to changes in iron ore inventories and negotiation progress [3]. - **Strategy**: Sideways to bearish for single - sided trading, no strategies for inter - period, inter - variety, spot - futures, or options trading [4]. Coking Coal and Coke - **Market Analysis**: Yesterday, the main futures contracts of coking coal and coke oscillated weakly. As the holiday approaches, more coal mines are announcing shutdowns, leading to a light trading atmosphere, with many auctions failing and prices falling in the coking coal market. The spot prices of coke in the main production areas and ports are relatively stable, and coke producers' production is relatively stable. After the first round of coke price increases, coke producers' profits have improved, but most steel mills have completed winter restocking, leading to a sharp decline in speculative demand for coke [5]. - **Supply and Demand Logic**: In the short term, coke prices are expected to oscillate and follow cost fluctuations. For coking coal, as steel mill hot metal production has recovered, the rigid demand for coking coal remains resilient. However, as downstream restocking nears completion, speculative demand has declined. As the Spring Festival approaches, more coal mines are shutting down for the holiday, and Mongolian coal imports will be suspended during the Spring Festival, alleviating the supply pressure on coking coal. Before the Spring Festival, coal prices are expected to remain stable with narrow adjustments. Attention should be paid to the resumption of domestic coal production after the festival [6]. - **Strategy**: Sideways for both coking coal and coke in single - sided trading, no strategies for inter - period, inter - variety, spot - futures, or options trading [6]. Thermal Coal - **Market Analysis**: In the production areas, more private mines in the main production areas are on holiday, leading to a tightening supply. Downstream demand, except for some chemical industries, has shrunk significantly. Before the holiday, prices are expected to change little, and attention should be paid to the recovery of market supply and demand after the holiday. At ports, as the Spring Festival approaches, downstream users are on holiday, and terminal daily consumption is continuously declining, resulting in low market activity. Affected by the tightening supply at the mine mouth, market supplies to ports are tight, and port shipments are in a continuous loss - making situation. Currently, the market shows weak supply and demand, and prices remain stable. In the import market, the tender prices of imported coal are continuously rising. Due to uncertainties in the later production policies of Indonesian mines, prices are relatively high [7]. - **Supply and Demand Logic**: Recently, due to coal mine holidays, supply has shrunk, and downstream factories are also gradually taking holidays, resulting in weak supply and demand. Affected by supply in the import market, domestic thermal coal prices have maintained a slight upward trend. Recently, the full approval of the RKAB of a leading Indonesian mine is expected, and the approval results of other mines will be announced successively. In the later period, Indonesian supply is expected to recover. Overall, before the holiday, the upside for prices is limited, and they are expected to remain stable to slightly bullish. After the holiday, as coal mine supply resumes and the peak season nears its end, prices may face downward pressure [7].

In East China, the civilian end of liquefied gas remained stable while the ether - after product prices decreased. The upstream focused on sales volume, and the downstream purchasing enthusiasm was acceptable. Overseas supply tightened marginally, but the PG futures market was relatively weak. High raw material costs suppressed downstream profits, and the price inversion between ether - after carbon four and civilian gas also put pressure on the PG market. There were also disturbances from warehouse receipts and delivery games [1] - Short - term attention should be paid to the Iranian situation. If the conflict escalates, it may lead to a significant tightening of domestic supplies and potential upward risks for the market. If the situation eases, the LPG market is still expected to be oversupplied [1] Summary by Relevant Directory Market Analysis - Regional prices of liquefied gas in different markets in China on February 10 [1] - CIF prices of frozen propane and butane in East and South China in the first half of March 2026 and their RMB equivalent [1] - The mixed trend of domestic liquefied gas spot prices, the situation of the civilian end and ether - after product in East China, upstream and downstream conditions, overseas supply, and the influence factors on the PG market [1] - The need to focus on the Iranian situation and its potential impact on the market [1] Strategy - Unilateral strategy: Neutral, focus on the Iranian situation and maintain a light position before the festival [2] - Other strategies (inter - period, cross - variety, spot - futures, options): None [2] Figures - Figures showing the spot prices of civilian liquefied gas and ether - after carbon four in different regions, as well as the closing prices, month - to - month differences, and trading volume and open interest of PG futures contracts [3]

1. Report Industry Investment Rating - Not provided in the given content 2. Report's Core View - The price of industrial silicon is expected to maintain a range - bound fluctuation. The supply side has significantly shrunk, providing obvious price support, but the high inventory of polysilicon suppresses demand, and the price lacks upward momentum. The upward potential depends on the recovery of downstream demand and inventory clearance progress, while the downward space is limited by cost support and production cut expectations [1][2] - The price of polysilicon is expected to continue to fluctuate. Although the supply side has shrunk significantly in February, providing support for prices, the demand side remains weak due to downstream cost constraints. The large - scale inventory is being cleared slowly, suppressing price increases. There is no obvious driving force for the "rush to export" phenomenon before April, and we need to wait for the supply - demand game [3][5] 3. Summary by Related Categories Industrial Silicon Market Analysis - On February 10, 2026, the futures price of industrial silicon fluctuated and fell. The main contract 2605 opened at 8430 yuan/ton and closed at 8375 yuan/ton, a change of (- 130) yuan/ton or (- 1.53)% from the previous day's settlement.

Silicon prices in Kunming, Huangpu Port, Northwest, Tianjin, Xinjiang, Sichuan, and Shanghai remained flat, and the price of 97 silicon was stable [1] - As of February 5, the total social inventory of industrial silicon in major regions was 56.2 tons, an increase of 1.44% from the previous week [1] - The demand for industrial silicon continued to be weak. The pre - holiday stocking was nearing the end, there were no new orders, large polysilicon manufacturers cut production, and the market was mainly focused on inventory clearance [1] - Large manufacturers have plans to cut production and stop work in February, and with the Spring Festival approaching, the supply is expected to shrink [1] Strategy - The price of industrial silicon is expected to maintain a range - bound fluctuation. Short - term range operation is recommended for unilateral trading, and there are no strategies for cross - period, cross - variety, and options trading [2] Polysilicon Market Analysis - On February 10, 2026, the main futures contract 2605 of polysilicon fluctuated and fell, opening at 48815 yuan/ton and closing at 48950 yuan/ton, a change of - 1.23% from the previous trading day.

The weekly production of polysilicon was 20100.00 tons, with a month - on - month change of - 0.50%, and the silicon wafer production was 10.38GW, with a month - on - month change of - 11.66% [3] - The prices of silicon wafers, battery chips, and components remained stable. There were no quotes and transactions for mainstream polysilicon products this week. Market sentiment was more cautious than last week, new orders were completely stagnant, and only a few companies had small - scale exploratory inquiries. Downstream companies were mainly digesting existing inventories, and the purchasing willingness was extremely low [3][4] Strategy - The price of polysilicon is expected to continue to fluctuate. Short - term range operation is recommended for unilateral trading, and the main contract is expected to maintain a slight fluctuation in the short term. There are no strategies for cross - period, cross - variety, and options trading [5]
