Report Summary 1) Report Industry Investment Rating No information provided. 2) Core Views of the Report - The recent decline in nickel prices is due to the superposition of fundamental pressures, with the continuous weakness of ferronickel prices being the direct cause and the decline in nickel sulfate demand exacerbating the surplus expectation of refined nickel [2][5][12]. - The short - term support level for nickel prices may be around 115,000 yuan/ton, but it is not recommended to buy at this level [12]. 3) Summary by Related Contents Recent Nickel Price Decline - Recently, nickel prices broke through the previous shock platform, with the Shanghai nickel main contract closing at 117,080 yuan/ton on November 14, a decline of 2.16%, and the LME nickel at $14,860/ton, a weekly decline of 1.07% [5]. - The decline is due to the continuous growth of refined nickel inventory since October, the accelerated decline of ferronickel prices since November, the expected increase in refined nickel supply, and the weakening demand for nickel sulfate [5]. Weak Ferronickel Price and High - Ice Nickel Conversion Expectation - Stainless steel demand is weak, driving down ferronickel prices. As of November 14, the domestic high - nickel pig iron ex - factory price has dropped to around 900 yuan/nickel point [7]. - The price deviation between refined nickel and ferronickel has led to a higher premium of refined nickel, increasing the expectation of ferronickel conversion to high - ice nickel. High - ice nickel production reached 36,000 tons in October and is expected to increase in November [7]. Weakening Nickel Sulfate Demand - Affected by the over - expected growth of new energy vehicles, ternary battery production was strong in the third quarter, but nickel sulfate demand may have reached its annual high seasonally [9]. - The cancellation of the new energy vehicle purchase tax exemption policy in 2026 may lead to a decline in new energy vehicle sales, and a significant drop in the premium of nickel sulfate over refined nickel may push intermediates into the refined nickel market, exacerbating the surplus expectation [9]. Short - Term Support for Nickel Prices - The continuous weakness of ferronickel prices and the decline in nickel sulfate demand are the main reasons for the decline of refined nickel prices [12]. - The current ferronickel profit level is at an absolute low, and the ferronickel price may be close to a phased low. The corresponding nickel price support level is around 115,000 yuan/ton [12].

Report Title - "Weak Decline with Limited Downside Space – Weekly Report on Non-ferrous Metals (Nickel) by Guoxin Futures" dated November 16, 2025 [2][3] Report Core View - The Shanghai nickel futures showed a weak downward trend this week. Refined nickel production remained high while demand was insufficient. The supply from the Philippines was affected by the rainy season and Typhoon "Seagull", with shipping stagnant, while the nickel ore market in Indonesia was relatively loose. The price of nickel sulfate was firm due to increased downstream demand, and the mid - term trend was yet to be observed with new capacity coming on stream.

Report Industry Investment Ratings No relevant content provided. Core Views Copper - Overseas liquidity is tight, and the strong US dollar index suppresses copper prices. After the reduction of interest rates and tariffs, the market may enter a macro "vacuum period" in November. The next macro nodes may be the December FOMC meeting, the domestic Politburo meeting, and the Central Economic Work Conference. Pay attention to the Fed's interest - rate cut rhythm and Sino - US tariff situation. - The supply of copper ore remains tight, and the spot TC of copper ore stays at a low level. If the prices of by - products such as sulfuric acid continue to fall, there may be a phased reduction in smelting production. The downstream's psychological price ceiling for copper prices gradually moves up. The downstream demand for copper is resilient, and there are still many purchase orders after price declines. In the long - term, the supply - demand contradiction supports the upward movement of the copper price's bottom center [1]. Aluminum - Alumina prices are expected to remain weakly volatile, with the main contract reference range of 2750 - 2900 yuan/ton. The supply pressure is not substantially relieved, the demand is weak, and the cost support is gradually shifting down. Pay attention to the supply recovery progress of Guinea's bauxite, the impact of domestic environmental policies on production, and the inventory depletion rhythm. - Aluminum prices are expected to fluctuate between event - driven factors and weak reality in the short - term. The 21500 yuan/ton pressure level is crucial. If the inventory continues to accumulate, there is a risk of price correction to the 20500 - 20800 yuan/ton range [3]. Aluminum Alloy - The casting aluminum alloy market followed the aluminum price to rise and then fall. The supply of raw materials is tight, and the demand shows a mild recovery. The ADC12 price is expected to maintain a relatively strong volatile trend, with the main contract reference range of 20400 - 21000 yuan/ton. Pay attention to the supply of scrap aluminum, procurement costs, and inventory depletion [4]. Zinc - Against the background of concerns about LME zinc squeezing, Shanghai zinc oscillated at a high level. The supply of zinc is generally loose, but the subsequent production increase may be limited. The demand has no extraordinary performance, and the LME's low inventory causes squeezing risks, which support zinc prices. Zinc prices are expected to be volatile and relatively strong in the short - term, with the main reference range of 22300 - 23000 [7]. Tin - The supply of tin ore remains tight, and the improvement of supply within the year is limited. The demand is weak, and the contribution of new fields such as AI and photovoltaics is small. Considering the strong fundamentals, a strategy of buying on dips is recommended. Pay attention to macro - level changes and the supply recovery in Myanmar in the fourth quarter [9]. Nickel - The nickel market is in a weak and volatile state. The macro - sentiment is weak, and the supply of nickel ore from the Philippines is affected by the rainy season and typhoons, while that from Indonesia is relatively loose. The demand for stainless steel is weak, and the demand for ternary materials has limited sustainability. Nickel prices are expected to fluctuate within a range, with the main reference range of 118000 - 124000 [11]. Stainless Steel - The stainless - steel market is running weakly. The supply pressure still exists, the demand is not significantly boosted, and the social inventory is slowly decreasing. The short - term market is expected to be weakly volatile, with the main operating range of 12500 - 13000. Pay attention to macro - expectations and steel supply [13]. Lithium Carbonate - The lithium carbonate market is weakly volatile. Although the short - term fundamentals are strong, the trading logic has switched, and the news and capital drives are stronger. The price is expected to fluctuate and adjust, with the main reference range of 78000 - 82000 yuan [15].
