Report Summary Investment Rating - The industry's strength is rated as weak [2] Core Views - In the short - term, the fundamental situation of cast aluminum alloy is characterized by weak supply and demand. As the off - season deepens, the negative feedback of demand is evident. Cast aluminum alloy enterprises reduce their开工率 due to sales pressure, which reduces the demand for scrap aluminum, suppresses scrap aluminum prices, and loosens the downside space. In the short term, cast aluminum alloy prices are expected to be under pressure during the off - season, and a short - selling strategy is recommended [6]. - Considering historical seasonality, the monthly structure is highly likely to show a Back pattern in the third quarter. Market participants can still focus on entering inter - period positive spreads at low prices and expect to realize profits during the peak consumption season [6]. - Usually, when the ADC12 - A00 spread converges, one can enter a short - AD long - AL position. However, currently, the profit - loss ratio of this position is not good. In the third quarter, as automobile production ramps up, driving positive feedback on ADC12 demand, one can pre - arrange a long - AD short - AL position [6]. Section Summaries Supply - Scrap Aluminum - Scrap aluminum production is at a high level, and social inventory is at a medium - high level in history [9]. - Scrap aluminum imports are at a high level, but the year - on - year growth rate is declining.

Report Industry Investment Rating - The report does not explicitly mention the industry investment rating. Core Views - In the short - term fundamental aspect, the casting aluminum alloy market is in a stage of weak supply and demand. As the off - season deepens, negative demand feedback appears. Casting aluminum alloy enterprises reduce their production due to sales pressure, leading to a decrease in demand for scrap aluminum, a rise in the refined - scrap price difference, and lower costs. In the short term, the price of casting aluminum alloy is expected to face pressure during the off - season, with a bearish outlook [6]. - Considering historical seasonality, the monthly structure is likely to show a Back pattern in the third quarter. At the initial listing stage, market participants can layout inter - period long - spread positions. After the near - end structure becomes Back, they can also consider entering inter - period long - spread positions at low prices and expect to realize profits during the peak consumption season [6]. - Usually, when the ADC12 - A00 price difference converges, one can enter a short - ADC12 and long - A00 position. Currently, the profit - loss ratio of this position is not good. In the third quarter, as automobile production increases, the demand for ADC12 will be positively affected, and one can pre - arrange a long - ADC12 and short - A00 position [6].

1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - The risk appetite in the stock market has rebounded moderately, creating a relatively strong pattern. The index is in a slow - bull state with prominent structural market conditions, driven by limited external risk disturbances, stable domestic fundamentals and optimistic policy expectations, and the inflow of funds due to the shift from short to long positions [7]. - The cast aluminum alloy is expected to open high on the first day of listing but may decline later. It is recommended to pay attention to inter - period positive spreads and long AD short AL positions [8]. - The pulp market is affected by news but is expected to have limited upside due to high inventory and weak demand [10]. - Crude oil may continue to be strong in the short - term, with Brent having a chance to challenge $80 per barrel in the third quarter, but there is significant downward pressure in the medium - to - long - term [11]. 3. Summary by Related Catalogs 3.1 Stock Index - The current index is in a slow - bull state with prominent structural market conditions. External risk disturbances are limited, domestic fundamentals are stable, and policy expectations are optimistic. The inflow of funds due to the shift from short to long positions also contributes to the market. However, if the market rises too fast or there are new changes in the external environment, the index may experience greater fluctuations [7]. 3.2 Cast Aluminum Alloy - It is expected to open high on the first day of listing, with a possible 6 - 8% increase in the call auction. The listing price is significantly lower than the reasonable valuation. However, the fundamentals are weak, and it is likely to open high and fall low. It is recommended to pay attention to inter - period positive spreads and long AD short AL positions around mid - year [8]. 3.3 Pulp - The shutdown of a pulp mill by Fenbao Group boosts the market, but the upside is limited. June is the off - season for the downstream paper market, with weak terminal market performance, low raw material procurement enthusiasm of paper mills, and high inventory, making it difficult for the market to have an unexpected performance [10]. 3.4 Crude Oil - Short - term: Both domestic and foreign crude oil markets are relatively strong. Brent may challenge $80 per barrel in the third quarter. The actual increase in supply is lower than expected, and there are still positive factors such as the contraction of Iranian oil supply, low inventory in major regions, and slow growth of US shale oil supply. - Medium - to - long - term: There is significant downward pressure, and Brent may test $50 per barrel this year. It is recommended to hold long positions and positive spreads as appropriate [11]. 3.5 Other Commodities - **Gold and Silver**: Gold's non - farm payrolls slightly exceeded expectations, and silver had a technical breakthrough.

Core Viewpoint - The launch of aluminum alloy futures marks a significant development in China's metal futures market, with the first contract being the 2511 contract, and the market sentiment is cautious due to seasonal consumption factors and price differentials [1][4]. Industry Overview - The aluminum alloy futures market is structured from scrap aluminum to casting aluminum alloy, then to die-cast parts, with the transportation sector being the largest consumer [1]. - The primary delivery standard for the futures is ADC12, which is currently in a consumption off-season, leading to a significant price discount compared to A00 aluminum [1]. Market Dynamics - The current market sentiment is cautious, influenced by the seasonal demand and the price disparity between different quoting platforms, with Jiangxi Baotai generally offering lower prices compared to Shanghai Steel Union and Shanghai Nonferrous [2]. - The market is divided into two categories: high-quality aluminum water for mainframe manufacturers and lower-quality alloy ingots for secondary suppliers, affecting the delivery dynamics [2][3]. Supply and Demand Analysis - The second quarter is characterized as a consumption off-season, with limited support for aluminum prices due to low demand and high production capacity [4]. - Despite an overall surplus in aluminum alloy production, the actual circulation of alloy ingots is minimal, resulting in low social inventory levels of 10,000 to 20,000 tons, providing some support for prices [4]. Price Expectations - The expected price range for the first trading day of aluminum alloy futures is between 19,000 and 19,800 yuan per ton, with various factors influencing both the upper and lower limits of this range [5]. - The upper limit is based on recent pricing from Jiangxi Baotai and includes additional costs, while the lower limit considers historical cost and price differentials [5]. Trading Strategies - The initial trading strategy suggests a focus on short to medium-term trading, with a recommendation for competitive buying due to the low listing price, while also being cautious of potential price corrections [6]. - Additional strategies include considering options for hedging and potential arbitrage opportunities due to expected seasonal price peaks and price differentials between ADC12 and A00 [7].

1. Report Industry Investment Rating - The report does not explicitly mention an industry investment rating [1][5] 2. Core Viewpoints - The casting aluminum alloy market is in a significant off - season, showing weak performance. The price of scrap aluminum has declined, and ADC12 is relatively weak. In the short - term, the unilateral price of casting aluminum alloy is under pressure and may run weakly. The price difference between ADC12 and electrolytic aluminum still has room to decline. In the medium - to - long - term, a long - ADC12 and short - electrolytic aluminum position can be arranged at the end of the off - season, and attention can be paid to the inter - period positive spread position [3][5] 3. Summary by Related Catalogs Supply Side - Scrap Aluminum - Scrap aluminum production is at a high level, and social inventory is at a medium - to - high level in history. Scrap aluminum imports are at a high level, but the year - on - year growth rate has declined. The price of scrap aluminum has decreased, and the price difference between refined and scrap aluminum has increased. After the raw material price of alloy plants decreased, the cost has loosened, but the operating rate is expected to continue to decline due to demand limitations [8][9][13] Supply Side - Recycled Aluminum - The price of casting aluminum alloy has a slight short - term decline, and the spread between ADC12 and A00 has significantly converged. The regional price difference of casting aluminum alloy shows that the southwest region is relatively weak and presents certain seasonal patterns. The operating rate of casting aluminum alloy has slightly decreased, and the monthly operating rate is at a historical low. ADC12 is mainly made from scrap aluminum and is currently in a loss state. The explicit and implicit inventories of casting alloys have increased, and the import window of casting aluminum alloy is temporarily closed [19][22][27] Supply Side - Recycled Aluminum Rod - The production and inventory data of recycled aluminum rods are presented. The production of recycled aluminum rods in different regions and the proportion of factory inventory in different regions are also provided [38][40] Demand Side - Terminal Consumption - In terminal consumption, the production of fuel - powered vehicles has declined, which has affected die - casting consumption. The production of new energy vehicles, motorcycles, and some household appliances, as well as the automobile inventory warning index, are also presented in the report [45][46]

Group 1: Investment Ratings - Unilateral: Neutral; Arbitrage: Inter - period positive spread [4] Group 2: Core Views - The rising absolute price of zinc has weakened the purchasing enthusiasm in the spot market, and both the spot premium and monthly spread have slightly declined. The supply pressure remains, with a 10% supply growth expected in June and a long - term high - supply growth rate in the second half of the year. The impact of Sino - US tariffs on consumption has not yet appeared, and the consumption is guaranteed. The comprehensive decline in inventory strongly supports the zinc price, but there is a risk of weakening consumption in June [3] Group 3: Summary of Key Data Spot Market - LME zinc spot premium is -$26.08/ton. SMM Shanghai zinc spot price is 22,790 yuan/ton, up 20 yuan/ton from the previous trading day, and the spot premium is 590 yuan/ton, up 70 yuan/ton. SMM Guangdong zinc spot price is 22,660 yuan/ton, down 50 yuan/ton, with a flat spot premium of 460 yuan/ton. SMM Tianjin zinc spot price is 22,760 yuan/ton, down 20 yuan/ton, and the spot premium is 560 yuan/ton, up 30 yuan/ton [1] Futures Market - On June 3, 2025, the main contract of SHFE zinc opened at 22,330 yuan/ton and closed at 22,180 yuan/ton, down 105 yuan/ton. The trading volume was 155,440 lots, down 26,261 lots, and the open interest was 122,728 lots, up 6,114 lots. The highest price was 22,515 yuan/ton, and the lowest was 22,090 yuan/ton [1] Inventory - As of June 3, 2025, the total inventory of SMM seven - region zinc ingots was 77,400 tons, down 1,400 tons from the previous week. The LME zinc inventory was 137,350 tons, down 800 tons from the previous trading day [2]

Report Industry Investment Rating - Unilateral: Neutral. Arbitrage: Inter - period positive spread [5] Core View - Zinc prices maintain a volatile pattern. The current strong consumption supports zinc prices to oscillate at a high level, but consumption may face a test in June, and attention should be paid to inventory changes [1][4] Summary by Relevant Catalogs Important Data - **Spot**: LME zinc spot premium is -$20.21/ton. SMM Shanghai zinc spot price rose by 100 yuan/ton to 22,830 yuan/ton, and its premium decreased by 30 yuan/ton to 415 yuan/ton. SMM Guangdong zinc spot price rose by 170 yuan/ton to 22,860 yuan/ton, and its premium increased by 40 yuan/ton to 445 yuan/ton. SMM Tianjin zinc spot price rose by 110 yuan/ton to 22,840 yuan/ton, and its premium decreased by 20 yuan/ton to 425 yuan/ton [2] - **Futures**: On May 28, 2025, the main SHFE zinc contract opened at 22,380 yuan/ton and closed at 22,210 yuan/ton, down 200 yuan/ton from the previous trading day. Trading volume was 162,225 lots, a decrease of 180,952 lots from the previous day, and positions were 123,007 lots, an increase of 1,439 lots. The intraday price fluctuated between 22,200 - 22,485 yuan/ton [2] - **Inventory**: As of May 26, 2025, the total inventory of SMM seven - region zinc ingots was 78,800 tons, a decrease of 5,000 tons from the previous week. As of May 28, 2025, LME zinc inventory was 143,450 tons, a decrease of 7,700 tons from the previous trading day [3] Market Analysis - In the spot market, traders continued to hold up prices, and the spot premium remained relatively stable, but downstream procurement sentiment was poor. A zinc smelter in South China extended its maintenance, causing zinc prices to fluctuate and rise, but the rise lacked sustained momentum. Overseas mine output in Q1 was lower than expected, but domestic smelters had sufficient raw material inventories. TC is expected to rise in June, and smelting still has profits, so the supply pressure remains. The current strong consumption supports high - level volatility of zinc prices, but consumption may weaken month - on - month after June [4]

Report Summary 1. Report Industry Investment Rating - Unilateral: Neutral [5] - Arbitrage: Inter - period positive spread [5] 2. Report's Core View - After maintenance disturbances, zinc prices rose and then fell. The current strong consumption supports zinc prices to fluctuate at a high level, but consumption may face challenges in June, and there is a possibility of a month - on - month decline in consumption after June. Attention should be paid to inventory changes [1][4] 3. Summary According to Related Catalogs Important Data - **Spot**: LME zinc spot premium is -$21.55/ton. SMM Shanghai zinc spot price rose by 160 yuan/ton to 22,730 yuan/ton, and its premium rose by 55 yuan/ton to 445 yuan/ton. SMM Guangdong zinc spot price rose by 140 yuan/ton to 22,690 yuan/ton, and its premium rose by 35 yuan/ton to 405 yuan/ton. SMM Tianjin zinc spot price rose by 160 yuan/ton to 22,730 yuan/ton, and its premium rose by 55 yuan/ton to 445 yuan/ton [2] - **Futures**: On May 27, 2025, the main SHFE zinc contract opened at 22,185 yuan/ton and closed at 22,330 yuan/ton, up 135 yuan/ton from the previous trading day. The trading volume was 343,177 lots, an increase of 200,438 lots from the previous trading day. The open interest was 121,568 lots, an increase of 3,048 lots from the previous trading day. The intraday price fluctuated, with a high of 22,695 yuan/ton and a low of 22,175 yuan/ton [2] - **Inventory**: As of May 26, 2025, the total inventory of SMM seven - region zinc ingots was 78,800 tons, a decrease of 5,000 tons from the same period last week. As of May 27, 2025, LME zinc inventory was 151,150 tons, a decrease of 2,350 tons from the previous trading day [3] Market Analysis - In the spot market, traders' supplies were tight, and concerns about the maintenance of smelters in South China pushed up the spot premium. However, downstream buyers were reluctant to buy at high prices, and the purchase enthusiasm was poor due to the supplement of imported supplies. A zinc smelter in South China extended its maintenance, causing zinc prices to fluctuate and rise, but the rise lacked sustainable momentum, and supply pressure pushed zinc prices back into the oscillation range [4] - Overseas mine production in Q1 was lower than expected, but TC will continue to rise in June. Even at the current TC price, smelting is still profitable, and smelting enthusiasm remains high, so supply pressure persists. Domestic smelters have sufficient raw material inventories, and there is no condition for a short - term TC reduction [4]
