Report Summary 1. Report Industry Investment Rating No information provided on the industry investment rating. 2. Core View of the Report The report indicates that the PVC market has significant domestic supply - demand contradictions. With high inventory pressure likely to persist, short - term V2601 is expected to fluctuate weakly in the range of 4500 - 4630 yuan/ton. The decrease in raw material prices has led to a decline in production costs, but due to weak spot prices, losses in both calcium carbide and ethylene methods have deepened. As the temperature drops, downstream demand in infrastructure and real estate is expected to weaken seasonally, and overseas demand remains uncertain [2]. 3.

Core Viewpoint - The tin market is experiencing fluctuations with the main contract rising by 1.04% to 286,560 yuan/ton, influenced by tight domestic ore supply despite long-term easing expectations from Myanmar's Wa State resumption of production [1] Supply and Demand Dynamics - Domestic mining sources remain tight, impacting the overall supply of tin [1] - The operating rate of tin smelting plants in Yunnan and Jiangxi stabilized at a high of 69.13%, but further increases are limited due to ongoing tightness in tin ore supply [1] - The seasonal maintenance of large smelting plants in Yunnan has concluded, leading to production recovery, but the supply of tin ore remains constrained [1] Market Conditions - Despite the approval of mining licenses in Myanmar's Wa State, actual export volumes are significantly below normal levels due to the rainy season and slow resumption of production, failing to fill the supply gap [1] - Recent declines in tin prices have spurred some downstream replenishment demand, but limited warehouse arrivals have resulted in a reduction of social tin inventory [1] Future Outlook - Jinrui Futures comments that recent price fluctuations are primarily driven by macroeconomic disturbances, with a slight accumulation expected under domestic baseline conditions, while overseas markets continue to experience low inventory levels [1] - Overall, the divergence between macroeconomic factors and fundamentals suggests that tin prices are likely to maintain a high-level oscillation [1]

Report Title - Nickel and Stainless Steel Industry Chain Weekly Report, dated October 31, 2025 [1] Report's Core Views Bullish Factors - Strong demand in the new energy sector, with increased production of ternary precursors, is driving up the price of nickel sulfate [3]. - High prices of nickel ore, and with the rainy season approaching in the Philippines, mines are more inclined to hold prices [3]. Bearish Factors - Weak fundamentals of refined nickel, with continuous accumulation of social inventory, suppressing the rebound of nickel prices [3]. - Insufficient demand in the stainless - steel sector, and the "Golden October" peak season was lackluster, with high social inventory [3]. Trading Advisory View - The macro sentiment and the current situation of fundamental oversupply counterbalance each other, limiting the upside potential of prices [3] Market Data Summary Nickel Futures - The closing prices of SHFE nickel contracts (main, continuous 1, 2, 3) decreased by -1.16%, -0.96%, -0.98%, -0.98% respectively, and LME nickel 3M decreased by -0.90%.

Report Industry Investment Rating - Aluminum: Cautiously bullish [9] - Alumina: Neutral [9] - Aluminum alloy: Cautiously bullish [9] Report Core View - In the long - term, with supply constraints, the high industry profit is not a factor limiting the rise of aluminum prices. Short - term price increases require resonance of positive macro and strong micro - consumption. In the current off - season, there is a small increase in social inventory, and long - term long opportunities can be considered after short - term pullbacks. For alumina, the current price is undervalued, but the supply - demand surplus pattern remains unchanged, and the replenishment behavior of electrolytic aluminum plants is hard to sustain. [6][7][8] Summary According to Related Catalogs Aluminum Spot - On October 30, 2025, the price of East China A00 aluminum was 21,200 yuan/ton, up 30 yuan/ton from the previous trading day, with a spot premium of - 10 yuan/ton, up 20 yuan/ton from the previous trading day; the price of Central China A00 aluminum was 21,060 yuan/ton, with a spot premium of - 150 yuan/ton, up 10 yuan/ton from the previous trading day; the price of Foshan A00 aluminum was 21,070 yuan/ton, unchanged from the previous trading day, with a spot premium of - 135 yuan/ton, down 5 yuan/ton from the previous trading day. [1] Aluminum Futures - On October 30, 2025, the main contract of Shanghai aluminum opened at 21,290 yuan/ton, closed at 21,245 yuan/ton, down 10 yuan/ton from the previous trading day, with a high of 21,360 yuan/ton and a low of 21,210 yuan/ton. The trading volume was 168,592 lots, and the open interest was 275,967 lots. [2] Aluminum Inventory - As of October 30, 2025, the domestic social inventory of electrolytic aluminum ingots was 619,000 tons, down 7,000 tons from the previous period; the warrant inventory was 66,418 tons, up 374 tons from the previous trading day; the LME aluminum inventory was 459,525 tons, down 3,225 tons from the previous trading day. [2] Alumina Spot Price - On October 30, 2025, the SMM alumina price in Shanxi was 2,845 yuan/ton, in Shandong was 2,790 yuan/ton, in Henan was 2,865 yuan/ton, in Guangxi was 3,015 yuan/ton, in Guizhou was 3,025 yuan/ton, and the FOB price of Australian alumina was 319 US dollars/ton. [2] Alumina Futures - On October 30, 2025, the main contract of alumina opened at 2,875 yuan/ton, closed at 2,816 yuan/ton, down 28 yuan/ton from the previous trading day's closing price, a change of - 0.98%, with a high of 2,879 yuan/ton and a low of 2,803 yuan/ton. The trading volume was 436,078 lots, and the open interest was 392,755 lots. [2] Aluminum Alloy Price - On October 30, 2025, the purchase price of Baotai civil raw aluminum was 16,800 yuan/ton, and the purchase price of mechanical raw aluminum was 17,000 yuan/ton, unchanged from the previous day. The Baotai quotation of ADC12 was 20,800 yuan/ton, unchanged from the previous day. [3] Aluminum Alloy Inventory - The social inventory of aluminum alloy was 73,500 tons, and the in - factory inventory was 58,700 tons. [4] Aluminum Alloy Cost and Profit - The theoretical total cost was 20,905 yuan/ton, and the theoretical profit was - 5 yuan/ton. [5] Market Analysis - **Electrolytic Aluminum**: The smelting profit has expanded to 4,000 yuan/ton in the off - season. In the long - term, with supply constraints, high profit is not a limiting factor for price increase. In the short - term, price increase needs positive macro and strong consumption. In the current off - season, social inventory has a small increase, and it is expected to accumulate slightly in July. Even after accumulation, the inventory is still at a historical low level, and delivery risks should be long - term vigilant. [6] - **Alumina**: The spot price of alumina is low, and electrolytic aluminum plants are actively purchasing forward alumina due to rich profits and winter storage demand. The market activity has increased, but the supply - demand surplus pattern remains. The cost of the northern ore supply is still tight, and the import ore is slightly declining. The reduction of ore price does not improve the alumina smelting loss, and the ex - factory price is under greater pressure. [7][8] Strategy - **Unilateral**: Bullish on aluminum with caution, neutral on alumina, and bullish on aluminum alloy with caution. [9] - **Arbitrage**: Long the near - term and short the far - term in Shanghai aluminum. [9]

Report Summary 1. Report Industry Investment Rating No information provided. 2. Core Viewpoints - PVC is in a state of high production and weak demand, with an expected increase in inventory in the future. The fundamentals are difficult to improve, but the valuation is at a relatively low level, and there may be positive macro - level news, so it is expected to show a short - term oscillatory trend. Technically, V2601 should pay attention to the support around the previous low of 4644 and the pressure around the 20 - day moving average of 4812 [3]. 3. Summary by Relevant Catalogs a.

Industry News - From October 11th to 17th, the capacity utilization rate of Chinese PVC was 76.69%, a significant decline compared to the previous period. The downstream operating rate of PVC increased by 9.38% to 48.59%, with the pipe operating rate increasing by 7.17% to 40% and the profile operating rate increasing by 17.39% to 33.26% [3]. - As of October 16th, the social inventory of PVC decreased by 0.24% to 1.0338 million tons compared to the previous week. The average cost of calcium carbide - based PVC increased to 5142 yuan/ton, and the national average cost of ethylene - based PVC decreased to 5432 yuan/ton. The profit of calcium carbide - based PVC decreased to - 731 yuan/ton, and the profit of ethylene - based PVC decreased to - 552 yuan/ton [3]. c. Outlook - This week, many PVC plants are expected to restart, and the impact of newly shut - down plants is limited, so the capacity utilization rate of PVC is expected to return to a high level. In October, there are few maintenance plants and new production capacity is increasing, resulting in relatively high supply pressure [3]. - The real estate market remains weak, and downstream orders are poor. Downstream is expected to maintain just - in - time procurement. Affected by India's anti - dumping tax, the export market may remain on the sidelines. Due to the high - production and weak - demand situation of PVC, there is still an expectation of inventory accumulation in the future [3]. - The calcium carbide - based process is deeply in the red, and chlor - alkali enterprises use caustic soda profits to offset chlorine losses. However, the supply of calcium carbide is abundant and the price is weak, so the cost - side support is limited [3].

Report Summary 1. Report Industry Investment Rating No information provided. 2. Core Viewpoints - PVC is in a state of high operation and weak demand, with a possibility of inventory accumulation in the future. The fundamentals of PVC remain weak, and there may be a correction after a phased rebound in the market. Technically, for V2601, attention should be paid to the support of the 5 - day moving average around 4691 and the pressure of the 20 - day moving average around 4836 [3]. - This week, a large number of PVC devices are set to restart, and the impact of newly shut - down devices is limited. The PVC capacity utilization rate is expected to return to a high level. With fewer maintenance devices and new production capacity coming online in October, the supply pressure is relatively high [3]. - The real estate market remains weak, and product orders are poor. Downstream is expected to maintain rigid procurement. Affected by India's anti - dumping tax, the export market may remain on the sidelines [3]. - The cost of the calcium carbide process has increased, while that of the ethylene process has decreased. Due to the larger decline in spot prices than costs, losses in both processes have deepened. Currently, calcium carbide enterprises are in deep losses, and the cost - side support has been weakened [3]. 3.

Report Industry Investment Rating - No specific industry investment rating is provided in the report. Core Viewpoints - The demand for both PE and PP remains weak, which continues to limit their upward potential and is still constrained by supply - side pressure. The recovery of demand is slow, and the cost support is insufficient. For PE, the supply is increasing, and the demand realization rate is slow; for PP, the supply pressure is large, and the profit at a low level restricts its downward space [3]. Summary by Relevant Catalogs Market News and Important Data - **Price and Basis**: L main - contract closed at 7,169 yuan/ton (+27), PP main - contract at 6,898 yuan/ton (+21). LL North China spot was 7,130 yuan/ton (+50), LL East China spot 7,140 yuan/ton (+30), PP East China spot 6,750 yuan/ton (+20).
