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. The short - term price is expected to oscillate between 77200 - 79200 yuan/ton for SHFE copper and 9450 - 9800 dollars/ton for LME copper [1]. Aluminum - Last week, SHFE aluminum closed flat, and LME aluminum rose 0.12% to $2451/ton. Domestic aluminum ingot inventories continued to decline, and the spot basis decreased. The supply increased slightly, and demand weakened. The price is expected to fluctuate between 19800 - 20200 yuan/ton for SHFE aluminum and 2380 - 2500 dollars/ton for LME aluminum [3]. Lead - As of Friday, SHFE lead index rose 0.49% to 16775 yuan/ton, and LME lead 3S rose to $1990.5/ton. Fed's dovish remarks and strong non - farm data may drive a small rebound, but weak downstream consumption and high inventories will keep prices weak [4]. 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. Due to capacity surplus, prices are expected to be cost - anchored, and it is recommended to short on high prices. The main contract AO2509 is expected to range from 2800 - 3200 yuan/ton [13]. Stainless Steel - On Friday, the stainless - steel main contract closed at 12680 yuan/ton. Spot prices were mostly stable, and inventories increased. The market will continue to be under pressure due to high inventory, weak demand, and other factors [15].

Report Summary 1. Report Industry Investment Rating No investment rating is provided in the report. 2. Core View of the Report On May 20, polysilicon showed a weak oscillating trend, with the main contract 2506 closing at 35,625 yuan/ton, a daily decline of 0.99%, and an increase in positions by 7,474 lots to 70,536 lots. The price of SMM N-type polysilicon material dropped to 37,500 yuan/ton, and the spot premium over the main contract widened to 975 yuan/ton. Industrial silicon fell below the 8,000-yuan mark, with the main contract 2506 closing at 7,910 yuan/ton, a daily decline of 2.53%, and a decrease in positions by 10,324 lots to 64,706 lots. The reference price of Baichuan industrial silicon spot decreased by 73 yuan/ton to 9,412 yuan/ton, and the price of the lowest deliverable 553 grade dropped to 8,100 yuan/ton, with the spot premium widening to 95 yuan/ton. Leading silicon factories in Xinjiang have actively cut production, and the industry is calling for joint production cuts, which will temporarily relieve the supply pressure. However, due to the lack of a reversal driver in demand and the suppression of warehouse receipt pressure, a defensive short strategy is recommended. Polysilicon is facing a structural contradiction between a shortage in near-term delivery and a rapid loss of demand. After the squeezing pressure on the main contract ends, it is inevitable for the price to weaken, and the rebound height will be lower than before [2]. 3.

Report Industry Investment Rating No relevant information provided. Report's Core View PVC and Caustic Soda - In the short term, the supply pressure of caustic soda is limited during the concentrated maintenance period, and the demand from the alumina sector has improved. Supported by fundamental supply - demand and positive macro - drivers, the spot price of caustic soda tends to be strong. However, attention should be paid to the price acceptance of non - aluminum sectors and the valuation of caustic soda. It is recommended to wait and see in the short term [7]. - For PVC, in the short term, the supply - demand contradiction is limited due to concentrated maintenance and limited inventory pressure. There is an expectation of rush - exporting PVC products. But in the medium and long term, there is an obvious over - supply pressure. It is recommended to wait and see, with a short - term rebound and a medium - term short - selling approach [7]. Polyester Industry Chain - For PX, in the short term, the supply is tight and the demand is supported, but the upward pressure on crude oil and the possible production cut of downstream products may put pressure on PX. It is recommended to treat it as a high - level shock, exit the PX09 - 1 positive spread, and pay attention to the reverse spread opportunity [12]. - For PTA, the short - term supply - demand is tight, but there is an expectation of weakening. It is recommended to treat it as a high - level shock, exit the TA09 - 1 positive spread at a high level, and pay attention to the reverse spread opportunity [12]. - For ethylene glycol, it is expected to reduce inventory in May, and it is recommended to take profit on the short - put option EG2509 - P - 4250 seller and conduct a long spread on EG9 - 1 [12]. - For short - fiber, the short - term inventory pressure is not large, but the processing fee is compressed. It is recommended to take the same strategy as PTA for single - side trading and expand the processing fee at a low level [12]. - For bottle - chips, the short - term supply - demand contradiction is not prominent, and the price follows the raw materials. It is recommended to pay attention to the opportunity of expanding the processing fee at the lower edge of the 350 - 550 yuan/ton range [12]. Styrene The short - term rebound of styrene is supported by low inventory and improved demand expectations. However, the high - production and high - inventory problems of 3S products and the poor supply - demand of pure benzene may limit the rebound height. It is recommended to pay attention to the resistance above 7800 - 7900 in the near - month [18]. Methanol The inland valuation of methanol has a downward pressure, the port starts the inventory - accumulation period, and the 09 contract is under pressure. It is recommended to short - sell the MA09 contract at a high level [22]. Crude Oil The overnight oil price continued to decline due to the progress of the US - Iran nuclear agreement negotiation. The short - term market will be mainly in a wide - range shock. It is recommended to wait and see in the short term and capture volatility - amplification opportunities in the option market [26]. PE and PP The spot sentiment of PE and PP has weakened. The supply pressure will gradually decrease in May, but the cost - end rebound compresses the profit. Attention should be paid to the restocking and exporting of plastic products [29]. Urea The core logic of the rise in urea futures is the boost of the clear export policy. The short - term supply - demand is expected to be tight, but the actual increase depends on the policy implementation and export orders. The short - term disk will be in a wide - range consolidation [90]. Summary by Relevant Catalogs PVC and Caustic Soda Spot and Futures - On May 15, the prices of Shandong 32% liquid caustic soda and 50% liquid caustic soda were 2593.8 yuan/ton and 2760.0 yuan/ton respectively.

1. Report Industry Investment Rating No information provided in the content. 2. Core Views of the Report - On May 12, polysilicon showed a volatile and slightly stronger trend, with the main 2506 contract closing at 38,450 yuan/ton, an intraday increase of 2.49%, and the position increasing by 248 lots to 67,504 lots. Industrial silicon also showed a volatile and slightly stronger trend, with the main 2506 contract closing at 8,320 yuan/ton, an intraday increase of 0.24%, and the position decreasing by 1,216 lots to 16,900 lots [2]. - There was a small amount of seasonal production increase in the Southwest, and the production reduction progress in the Northwest was slow. The industry inventory was still accumulating. At the current low position of the futures price, it was difficult for enterprises to conduct hedging, and industrial silicon continued to be in a state where it was easier to fall than to rise [2]. - The industry would hold another meeting on self - restricted production and price support for polysilicon, and the release rhythm of planned new production capacity might be postponed. As the delivery period approached, the ratio of virtual to real warehouse receipts for polysilicon was too high, giving room for long - position players to compete. It was necessary to track the meeting results and the movement of warehouse receipts and be vigilant against abnormal risks before the delivery month [2]. 3. Summary by Relevant Catalogs 3.1 Research Views - Polysilicon and industrial silicon futures prices both showed a volatile and slightly stronger trend on May 12. The production situation in different regions led to inventory accumulation, and there were potential changes in the production capacity release rhythm due to industry meetings [2]. 3.2 Daily Data Monitoring Industrial Silicon - The futures settlement prices of the main and near - month contracts decreased by 20 yuan/ton from May 9 to May 12. Most of the spot prices of different grades and in different regions decreased, with the largest decrease of 100 yuan/ton.

1. Report Industry Investment Ratings No industry investment ratings are provided in the reports. 2. Core Views Urea - Despite high daily production, short - term maintenance led to a decline in daily output. The new export policy allows the release of supportive export orders from May to June, and the upcoming summer top - dressing season in May - June is expected to boost agricultural demand. Market price increases are likely to be cautious, and the futures market is expected to fluctuate at a high level in the near term [3]. Crude Oil - Oil prices continued to rise, driven by the progress of China - US trade negotiations and geopolitical uncertainties. In the short term, the market risk appetite has increased, but no strong trend has been formed yet, and the sustainability of the macro - drive needs to be observed. The monthly - line fluctuation ranges are adjusted to [57, 67] for WTI, [60, 70] for Brent, and [450, 510] for SC [7]. Styrene - Crude oil is expected to be weak in the medium term, putting pressure on chemical products. Pure benzene supply has decreased recently, but overall supply pressure remains due to imports. Styrene downstream demand is weak, and supply is expected to increase. It is recommended to maintain a short - selling strategy for styrene, with the upper resistance for the near - term contract at 7300 [13]. PE and PP - For LLDPE, although imports are expected to decline significantly from May to June and supply pressure will gradually decrease, inventory pressure is still large under the situation of weak supply and demand, and there is a long - term downward risk. For PP, supply pressure eases slightly during the second - quarter maintenance season, but production is still high, demand is weakening, and there is also a long - term downward risk [17]. Caustic Soda - In the medium - to - long term, the demand for caustic soda from alumina is insufficient, and new production capacity is being added, so the supply - demand outlook is weak. In the short term, caustic soda is in the maintenance phase, and the price has been supported. It is recommended to maintain a short - selling strategy, with the near - term resistance at 2550 [26]. PVC - The supply - demand surplus of PVC is prominent. Domestic demand is weak, and exports are mainly based on price - for - volume. The long - term surplus problem is difficult to solve, and the price is expected to remain weak. It is recommended to short on rallies, but there is a risk of price rebound during the maintenance period [26]. Methanol - The inland valuation has a downward pressure. After the spring maintenance, production has recovered, and downstream profits are differentiated. The port has entered a stock - building period, and the MTO low - operation rate suppresses demand. It is recommended to short the MA09 contract on rallies [35][38]. Polyester Industry Chain - PX: Tight supply and short - term strong demand support its price, but the rebound space is limited. PX09 is expected to fluctuate strongly in the short term, and PX9 - 1 is in a short - term positive spread situation [40]. - PTA: The supply - demand pattern remains tight in the short term, and the price is expected to be relatively strong compared to oil prices, but the rebound is suppressed. TA09 is expected to fluctuate strongly in the short term, and TA9 - 1 is in a short - term positive spread and medium - term reverse spread situation [40]. - MEG: Domestic supply is expected to increase in May, but short - term de - stocking is expected due to high polyester load and reduced imports. EG09 is expected to be strong in the short term [40]. - Short - fiber: Inventory pressure is low in the short term, but the driving force is weaker than that of raw materials. The processing fee is under pressure, and the absolute price fluctuates with raw materials [40]. - Bottle - chip: Supply and demand are both strong in the short term, and the absolute price fluctuates with raw materials. The processing fee is supported, and the main - contract processing fee is expected to fluctuate between 350 - 550 yuan/ton [40]. 3.
