Core Views Lithium Carbonate - The recent market sentiment is stable, and the market is mainly in a state of shock. However, there is a lack of actual positive news, and the short - term fundamentals still face pressure. In June, due to the boost in processing output and the increase in lithium extraction from some spodumene, the balance may be in surplus. The short - term market is expected to operate in a weak range, but the profit - to - risk ratio of short - selling is weakening, and the main contract is expected to operate between 56,000 - 62,000 yuan [1]. Nickel - Recently, the macro situation is temporarily stable, but the sentiment in the spot market is low. The cost support for refined nickel has slightly weakened, and the medium - term supply remains loose, restricting the upside space. The short - term fundamentals change little, and the market is expected to adjust through weak - range shock, with the main contract referring to 118,000 - 124,000 yuan [2]. Stainless Steel - The fundamentals remain weak. The ore end provides some price support, the negotiation range of nickel - iron prices has moved down, the stainless - steel production remains high, and the demand is weak with slow inventory reduction. In the short - term, there is still pressure on the fundamentals due to the supply - demand contradiction. The market is expected to operate weakly, with the main contract operating between 12,400 - 13,000 yuan [5]. Tin - The supply - side recovery is slow. In the short - term, tin prices are expected to be strong and fluctuate. However, considering the pessimistic demand outlook, it is advisable to short at around 260,000 - 265,000 yuan based on the inflection points of inventory and import data [7]. Aluminum - For aluminum, the short - term upper limit is around 20,500 yuan, and the price is expected to be around 20,000 yuan with a fluctuating trend. If the actual demand weakens in the third quarter, the price may find support at 19,000 - 19,500 yuan. For alumina, if the ore - end issues do not worsen, smelters may resume production after profit recovery, and the inventory is expected to gradually increase [8]. Zinc - In the long - term, zinc is in a supply - side loosening cycle. If the growth rate of the ore end is lower than expected and the downstream consumption performs better than expected, zinc prices may remain in a high - level shock pattern. In a pessimistic scenario, zinc prices may decline. It is advisable to short at high levels in the long - term, with the main contract focusing on the support at 21,000 - 21,500 yuan [10]. Copper - Under the combination of "strong reality + weak expectation", copper prices do not have a clear and smooth trend. The strong fundamentals limit the downward movement of prices, while the weak macro - expectations restrict the upside space. In the short - term, prices are expected to fluctuate, with the main contract referring to 77,000 - 80,000 yuan [13]. 3.

Report Industry Investment Rating No information provided Core View of the Report The supply of polyolefins is under pressure due to the expected restart of multiple previously shut - down plants and the ramp - up of new production capacities. The cost support for polyolefins has increased with the rising international crude oil prices. The propane price has been weakening, leading to a slight increase in the start - up rate of PDH - based PP production. It is the traditional off - season for polyolefin downstream demand, with the agricultural film start - up rate continuing to decline and other terminal start - up rates being weakly volatile. Terminal factories have low enthusiasm for raw material procurement, mainly making rigid - demand purchases. The inventories of upstream factories and traders are being slowly depleted. The strategy for plastics is to be cautiously bearish on the single - side, and there is no strategy for the inter - period [1][3][4] Summary According to Relevant Catalogs 1. Polyolefin Basis Structure The L main contract closed at 7106 yuan/ton (+28), the PP main contract closed at 6941 yuan/ton (+9), the LL spot price in North China was 7140 yuan/ton (+50), the LL spot price in East China was 7120 yuan/ton (+20), the PP spot price in East China was 7080 yuan/ton (+10), the LL basis in North China was 34 yuan/ton (+22), the LL basis in East China was 14 yuan/ton (-8), and the PP basis in East China was 139 yuan/ton (+1) [2] 2.

Report Industry Investment Rating There is no information about the industry investment rating in the provided content. Core Viewpoints - The sentiment towards copper is neutral, with short - term prices expected to oscillate at high levels due to factors such as raw material supply tightness, weakening consumption resilience, high near - month contract positions, and increased export expectations [1]. - Aluminum prices are expected to fluctuate weakly, supported by inventory depletion but pressured by tariff hikes and seasonal demand weakness [3]. - Lead prices are likely to remain weak as downstream consumption weakens despite potential small rebounds driven by a warmer commodity market [4]. - Zinc prices face significant downward risks due to oversupply and weak terminal consumption, despite possible small rebounds from a warmer market [6]. - Tin prices are supported by supply uncertainties and strong low - price buying demand, with the supply side facing short - term uncertainties [7]. - Nickel's short - term fundamentals show a slight improvement, but the long - term outlook is bearish, and it is advisable to short on rebounds [8]. - Lithium carbonate prices are expected to oscillate at the bottom as the short - term fundamentals remain unchanged and the inventory pressure persists [10]. - Alumina prices are expected to be anchored by costs, and it is recommended to short on high prices as the capacity surplus persists [13]. - Stainless steel market will continue to be under pressure in the short term due to high inventory, weak demand, and other negative factors [15]. Summary by Metals Copper - Last week, LME copper rose 1.83% to $9670/ton, and SHFE copper closed at 78620 yuan/ton. Three - exchange inventories decreased by 0.9 tons, with different trends in each exchange. The import loss of spot copper widened, and the export window for spot feed - processing opened.

Zinc - As of Friday, SHFE zinc index rose 0.14% to 22289 yuan/ton, and LME zinc 3S fell to $2690/ton. A warmer market may cause a small rebound, but oversupply and weak consumption pose significant downward risks [6]. Tin - Last week, tin prices rebounded from the bottom. Supply may face a 500 - 1000 - ton reduction in June, and smelters plan to cut production. Demand has not increased significantly, and downstream purchasing enthusiasm declines as prices rise. The price is expected to range from 230000 - 260000 yuan/ton domestically and 28000 - 31000 dollars/ton overseas [7]. Nickel - Last week, nickel prices oscillated. Nickel ore supply is tight, nickel - iron prices rebounded, MHP prices are high, and nickel sulfate prices may strengthen. The short - term outlook is slightly better, but the long - term is bearish. The price is expected to range from 115000 - 128000 yuan/ton for SHFE nickel [8]. Lithium Carbonate - The MMLC index was flat on Friday, and the futures contract rebounded slightly. The current lithium salt production is high, and the inventory pressure persists. The price is expected to oscillate at the bottom, with the main contract ranging from 59520 - 61540 yuan/ton [10]. Alumina - On June 6, the alumina index fell 1.36% to 2899 yuan/ton. The import window opened, and the inventory decreased.

Report Investment Rating - No investment rating provided in the report Core Viewpoints - The terminal downstream demand for polyolefins has entered the traditional off - season, with limited market demand, general restocking enthusiasm, mainly rigid - demand procurement, and a cold market trading atmosphere. The supply side continues to increase, and the supply - demand contradiction has not been significantly improved. Currently, the number of PE inventory maintenance devices has increased, alleviating the PE supply side. The previously shut - down PP devices have gradually restarted, and the upstream production inventory of polyolefins has been depleted. It is expected that the future supply will increase. The downstream demand is in the off - season, the agricultural film operating rate is at a low level, the packaging film operating rate fluctuates slightly, and the operating rates of industries such as plastic weaving and BOPP have increased slightly [2] - For the trading strategy, it is recommended to be cautiously bearish on plastics for single - side trading, and there is no strategy for inter - period trading [3] Summary by Directory 1.

Suggest PF unilateral trading similar to PTA and expanding PF processing fees at low levels [18]. - Bottle chips: Supply has an incremental expectation, but short - term supply - demand contradiction is not prominent. Suggest PR unilateral trading similar to PTA and focus on expanding processing fees at the lower end of the 350 - 550 yuan/ton range [18]. Urea Industry - The inventory pressure of domestic urea factories is becoming more obvious, and the market may continue to oscillate and bottom. The downward space of the futures market depends on cost support. Future attention should be paid to inventory inflection points, export port collection trends, and coal price fluctuations [28]. Polyolefin Industry - PE: Overall trading is weak, but supply before early June is reduced due to maintenance and imports are low. Demand improves due to tariff cuts, and inventory is expected to decrease. - PP: Supply pressure increases after late May, but there is short - term demand support. Suggest unilateral short - selling on rallies and LP spreads expansion [31]. Crude Oil Industry - OPEC+ is discussing further production increases in July, and industry members are over - producing. US commercial crude inventories are accumulating, and gasoline and distillate demand is weak. Short - term oil prices will oscillate widely.

1. Report Industry Investment Rating No investment rating information is provided in the report. 2. Core Views - **LLDPE & PP**: The overall trading was weak on Monday, and market sentiment deteriorated. For plastics, maintenance increased and some production shifted before early June, with low imports. Demand improved in the short - term due to tariff cuts, and there was an expectation of inventory reduction. For PP, the maintenance peak was in late May, and subsequent supply pressure would increase. Demand had short - term benefits but mid - term concerns. The static fundamentals were okay. For single - side trading, it was advisable to go short on rallies, and the LP spread was expected to widen [4]. - **PVC & Caustic Soda**: For caustic soda, in the short - term, supply pressure was limited during the concentrated maintenance period. Demand was supported by the potential resumption of some alumina production and new production lines. The purchase price of mainstream Shandong factories increased, and the futures price might rise further, but there were risks. It was recommended to stay on the sidelines, and aggressive investors could try positive spreads cautiously. For PVC, the short - term rebound was supported by macro - stimulation, export, and supply - demand factors, but there was an over - supply pressure in the long - term. It was expected to fluctuate in the short - term, with a resistance level of around 5100 for the 09 contract [26]. - **Polyester Industry Chain**: For PX, short - term supply was tight, and demand was supported, but the upside was limited. PX09 was expected to fluctuate in the range of 6600 - 7000, and PX9 - 1 was in a short - term positive spread situation. For PTA, the supply - demand situation was expected to weaken. TA09 was expected to fluctuate in the range of 4600 - 5000, and TA9 - 1 was short - term positive spread and medium - term negative spread. For MEG, there was an expectation of inventory reduction, and short - term support was strong. It was advisable to sell put options on EG2509 - P - 4300 and go for positive spreads on EG9 - 1. For short - fiber, the absolute price was expected to adjust, and attention could be paid to the opportunity to widen the processing margin. For bottle - chips, the absolute price followed the raw materials, and attention could be paid to the opportunity to widen the processing margin at the lower end of the range [30]. - **Crude Oil**: Oil prices were oscillating, and the future logic would shift from macro to fundamental factors. If OPEC's actual production increase was as expected, the market would be under pressure; otherwise, the pressure would be relieved. There was still a short - term geopolitical premium. Oil prices were likely to fluctuate within a certain range. The recommended trading strategy was a band - trading approach, with the WTI range at [59, 69], Brent at [61, 71], and SC at [450, 510]. It was advisable to buy volatility in options trading [34]. - **Methanol**: The port inventory showed an inflection point, and the expected increase in imports would lead to inventory accumulation and a weaker basis. The 09 contract was expected to decline in the short - term, and it was advisable to add positions at 2350, targeting 2050 - 2100. It was also advisable to reduce short - positions on the 69 reverse spread [37]. - **Styrene**: Styrene rebounded strongly. Tariff cuts improved demand expectations, and the inventory was at a low level. However, there were risks, including high inventory in the 3S products and weak pure - benzene supply - demand. It was expected to fluctuate in the short - term and be bearish in the medium - term. Attention could be paid to the resistance level of 7800 - 7900 for the near - month contract, and the opportunity for the EB - BZ spread to widen [42]. 3.
