Report Industry Investment Rating - Not provided in the given content Core Views - This week, the macro - sentiment continued to show an increase in risk appetite. Although domestic economic and financial data were poor, the stock market sentiment remained high. In the copper market, downstream orders had support around 7.8, and there were some disturbances in the scrap copper and recycled copper markets. An 8 - month supply - full pattern was expected to lead to a small inventory build - up, but the market might focus more on the tight - balance pattern after the off - season [1]. - For aluminum, supply increased slightly, and the demand in August was in the seasonal off - season, with a possible slight improvement in the middle and late stages. An inventory build - up was expected in August. Attention should be paid to demand and low - inventory situations [2]. - Zinc prices fluctuated widely this week. Supply - side issues included difficulties in the increase of domestic TC and an increase in imported TC. Demand was seasonally weak but had some resilience. Overseas, there might be a phased supply shortage. Short - term strategy was to wait and see, long - term was a short - position configuration, and there were opportunities for positive spreads in different aspects [3]. - Nickel's supply remained high, demand was weak, and inventories were stable. Opportunities for narrowing the nickel - stainless steel price ratio could be continuously monitored [6]. - Stainless steel's supply decreased due to some passive production cuts, demand was mainly for rigid needs with some increased restocking, costs were stable, and inventories decreased slightly. Attention should be paid to future policies [9]. - Lead prices fluctuated this week. Supply - side issues included weak scrap production and high recycled lead costs. Demand was not strong enough to cover the supply increase, and lead prices were expected to remain low and volatile next week [10]. - Tin prices fluctuated widely. Supply - side saw domestic smelter production cuts and uncertain overseas复产. Demand was weak in some areas and there was a risk of squeezing stocks in the LME. Short - term strategy was to short at high prices, and long - term was to hold at low prices near the cost line [12]. - Industrial silicon's production in Xinjiang was less than expected, while that in Sichuan and Yunnan increased slightly. In the short term, there was a small inventory reduction, and in the long term, it was expected to oscillate at the cycle bottom [13]. - Carbonate lithium prices were strong this week due to factors such as inventory reduction and production disturbances. The core contradiction was the long - term over - capacity and short - term resource - side disturbances. In the short term, prices had a large upward elasticity and strong downward support [15].

Report Industry Investment Rating - Not provided in the document Core View of the Report - The current market liquidity remains abundant, with A-share trading volume exceeding 2 trillion, and the Shanghai Composite Index breaking through the previous high. Under the influence of internal and external positive factors, market sentiment is good, and stock index futures may continue to run strongly. Asset shortage and weak economy are beneficial to bond futures, but the central bank's short-term reminder of interest rate risks suppresses the upward movement. The market risk appetite is still high, and the gold price may be disturbed in the short term, but the probability of an interest rate cut in September is still high, providing support for the gold price, which is expected to fluctuate mainly in the short term. The silver price is expected to fluctuate within a range in the short term, but will be mainly based on fundamental logic in the medium term. The expectation of an interest rate cut by the Federal Reserve in September boosts the copper price, while the domestic copper downstream demand is weak, and the copper price may fluctuate strongly. The recent decline in the US dollar index, but the pressure on the downstream demand of aluminum, leads to the weak operation of the aluminum price. The production and inventory of alumina both increase, with a weak fundamental situation, but the rainy season in Guinea reduces the bauxite shipment volume, and considering the anti-involution market may continue, attention can be paid to the opportunity of laying out long positions in the far month. The zinc price is under great pressure due to the increase in inventory and the recovery of supply. Considering the potential risk of a short squeeze in LME zinc, short selling should be cautious, and the opportunity of selling hedging at high positions can still be continuously concerned before the peak season. The macro-optimistic sentiment cools slightly. The premium of Indonesian nickel ore remains stable, and the demand side performs generally. The nickel price runs in a wide range in the short term, and attention should be paid to supply and macro changes. It is recommended to focus on short-term trading and wait for the opportunity of selling hedging at high positions. In the long term, the surplus of primary nickel still exerts pressure. The macro-optimistic sentiment cools slightly. The price of raw material nickel iron rises steadily, the social inventory of stainless steel decreases slightly, and steel mills resume production one after another after profit repair. Attention should be paid to the actual production situation of steel mills. The stainless steel futures run in a volatile manner in the short term, dominated by the macro situation. It is recommended to focus on short-term trading, wait for the opportunity of selling hedging at high positions, and pay attention to the opportunity of positive arbitrage between futures and spot. Fundamentally, tin is still in a situation of weak supply and demand. After a full correction, attention can be paid to the opportunity of going long at a low price. The supply of industrial silicon in the southwest and northwest regions resumes, with great hedging pressure and strong market sentiment. The polysilicon has an expectation of capacity reduction in the long term, low terminal installation willingness, and considerable profits. The resource end of scrap steel is frequently disturbed, and the short-term replenishment volume of the downstream is large, with limited subsequent replenishment space. The cost of electric furnace valley electricity provides a short-term support range for rebar, and the upward driving force follows coal. The upward driving force of hot-rolled coil follows the cost support anchored by coal, and it is slightly stronger in the short term. The near-month iron ore is restricted by production cuts, but the commodity sentiment is good, and there is still an upward opportunity in the far month. The anti-involution in ferromanganese and ferrosilicon is long-term, and in the short term, it is mainly affected by macro positives, with prices showing a strong trend. The glass still has a weak reality but strong expectations, with a pattern of near weakness and far strength. The soda ash still has a weak reality, affected by supply disturbances and macro positives, also showing a pattern of near weakness and far strength. The high-level meeting mentioned "anti-involution", and the market expects a bull market similar to the supply-side reform in 2015. Although it cannot be compared in all aspects, since it cannot be falsified in the short term at the trading level, short positions on the market should be temporarily avoided, and industrial customers should seize the opportunity of premium to establish positive arbitrage positions between futures and spot. The logic of coke is the same as that of coking coal, and the opportunity of selling hedging when the futures price has a premium should be mainly grasped. The MPOB report is less bearish than expected, and the production in August may be affected by heavy rainfall, with a short-term positive expectation difference. Indonesia's official announcement of implementing B50 next year brings a long-term "strong expectation" for palm oil. The expected reduction in soybean arrivals, the peak consumption season in the fourth quarter, and the opening of the export trade flow bring the expectation of inventory reduction in the fourth quarter, leading to a revaluation of soybean oil. The USDA's reduction of the new crop area in August and the Sino-US trade relationship lead to the firmness of the CBOT soybean price and the CNF premium of Brazilian soybean exports, supporting the upward movement of soybean oil from the raw material cost side. The reduction in the production of rapeseed in Russia and Ukraine and the less-than-expected increase in the production of sunflower seeds in the Black Sea region support the price of rapeseed oil in the new crushing season. The Ministry of Commerce's preliminary ruling that Canadian rapeseed is dumped will increase the customs duty deposit from August 14, bringing the expectation of a significant reduction in subsequent rapeseed supply. Cotton increases in positions and rises in the short term, dominated by the logic of a short squeeze in the near month. The height of the 01 contract is limited, and attention should be paid to the time window from the end of July to the beginning of August and the release of the sliding duty quota. White sugar runs strongly, with the bottom divergence rebound of raw sugar and the peak season demand, but the height is limited, and attention should be paid to the range fluctuation between 5600 - 6000. The supply and demand of old crops tend to be tight, but the pressure of warehouse receipts is large, and the expected rebound space of C09 is limited. Considering the expected selling pressure of new-season corn during the autumn harvest and the reduction in planting cost, a bearish view is maintained for the C11 and C01 contracts. The supply and demand balance sheet of new-season US soybeans is tight. Under the current Sino-US trade policy, the expectation of the Brazilian premium remains firm. Under the expectation of an increase in import cost, MO1 is expected to fluctuate strongly, but currently, the pressure on the domestic spot is still large, and the low basis restricts the increase of the futures price in the short term. Overall, the idea of buying on dips should be adopted. The external quotation of pulp is raised, with the price of Brazilian pulp increasing by $20 per ton in August, and the domestic inventory shows a reduction; but the recent decline in commodity futures is expected to lead to a volatile operation. The fundamentals of the log spot have improved recently, mainly reflected in the increase in the external quotation and the reduction of domestic port inventory; however, the delivery pressure in Chongqing restricts the motivation of log bulls to take delivery, and it is expected to fluctuate between 810 - 840 yuan/m³. The near-month contract of live pigs is dragged down by the spot and is relatively weak. The inventory will gradually recover in the second half of the year, and attention should be paid to the weight reduction and consumption situation. There are peak season expectations for the 11 and 01 contracts. The meeting between the US and Russia has not reached an agreement yet, but the progress is good; OPEC+ continues to increase production; the peak consumption season in Europe and the US has reached its peak, and there is a weakening trend later. The short-term supply and demand contradiction of fuel oil is not prominent, following crude oil; the cost disturbance and the recovery of demand balance each other, with limited fluctuations. The rainfall in the domestic rubber-producing areas causes disturbances, and the raw material cost provides strong support; the inventory reduction speed is slow; and the state reserve conducts a large amount of dumping. OPEC+ continues to increase production, and the fundamental situation of crude oil remains loose; the fundamental situation of synthetic rubber is severe, and downstream purchases are mainly for rigid demand; BR runs stably in a consolidation phase, and attention should be paid to the inventory levels of butadiene and BR9000 and the autumn maintenance situation of butadiene rubber plants. The supply of PTA has shrunk, and the crude oil price has slightly declined. The downstream load of polyester has decreased to 88%. The PTA port has a slight reduction in inventory, and the polyester replenishment willingness is not high. The coal price has slightly increased. The overall performance of the commodity sentiment has slightly weakened. The maintenance of overseas ethylene glycol plants has been postponed, the supply side has shrunk, and the market expects a reduction in future arrivals. The short fiber warehouse receipt registration volume is small, and the maintenance of short fiber factories has increased. Under the condition of a high basis, the cost of short fiber is closely followed, and there is no independent market in the market currently. The price of pure benzene has slightly declined, the shipment of styrene is active, and the crude oil price has weakened. The operating load of styrene plants has recovered, and the basis of styrene has significantly weakened. The export sentiment has slightly eased, and the domestic demand is insufficient, with limited upward space; there is support from anti-involution and the cost side below. The macro sentiment is warm; there are many maintenance operations; the demand is mainly for rigid needs, and the price fluctuates weakly. The maintenance support is limited; the orders are mainly for rigid needs; the macro situation is warm, and the futures price fluctuates strongly. The macro sentiment is warm; the maintenance has decreased compared with the previous period; the downstream has entered the seasonal off - season, and the supply pressure has increased, with the futures price fluctuating strongly. The spot is about to enter the peak season; the spot price has fallen to a low level; the coking coal price has risen again, and the macro sentiment is warm. OPEC+ continues to increase production, and the fundamental situation of crude oil remains loose; the market expects a reduction in future arrivals.

The spot is about to enter the peak season; the spot price has fallen to a low level; the coking coal price has risen again, and the macro sentiment is warm. OPEC+ continues to increase production, the supply of crude oil is abundant, and the synthetic rubber market is severe, with downstream purchases mainly for rigid needs. PTA supply contracts, crude oil prices fall slightly, polyester downstream load drops to 88%, PTA port inventory decreases slightly, and polyester replenishment willingness is low. Coal prices rise slightly, commodity sentiment weakens, overseas ethylene glycol plant maintenance is postponed, and supply contracts. Short - fiber warehouse receipt registration is low, factory maintenance increases, and with a high basis, cost follows closely and there is no independent market. Pure benzene prices fall slightly, styrene shipments are active, crude oil prices weaken, styrene plant load recovers, and the basis weakens significantly. Urea export sentiment eases, domestic demand is insufficient with limited upside, but there is anti - involution and cost support below.

OPEC+ continues to increase production, the supply of LPG is abundant, the downstream demand is weak, and the overall demand has a repair expectation; the warehouse receipts have reached a new high, and attention should be paid to the main contract delivery and the spread between September and October. The signal of the peak of the freight rate of the European container shipping line appears; the European ports are still congested; and there are many additional ships in August.

Group 1: Polyester Industry Report Industry Investment Rating Not provided Core View The report analyzes the price, cash - flow, and supply - demand situation of various products in the polyester industry. Different products have different trends and outlooks. For example, PX's supply is expected to increase marginally in August, and its supply - demand is expected to weaken; PTA's short - term supply - demand may improve, but it is expected to be weak in the medium - term; ethylene glycol's short - term supply - demand is expected to improve; short - fiber's supply and demand have a small increase, and its price follows raw materials; bottle - chip's inventory is slowly decreasing, and its processing fee has support [2]. Summary by Directory - **Product Prices and Cash - flows**: On August 8th, prices of some products like DTY150/48 decreased by 0.3%, while others like POY150/48 remained unchanged. Cash - flows of some products also changed, such as POY150/48's cash - flow decreased by 28.6% [2]. - **Supply - Demand Analysis**: PX supply increases in August, and with low terminal demand, its supply - demand weakens. PTA has new device production, but low processing fees lead to more unexpected device overhauls. Ethylene glycol has supply changes both at home and abroad, and demand is expected to increase as the off - season ends. Short - fiber's supply and demand slightly increase, and bottle - chip's inventory decreases due to production cuts [2]. Group 2: PVC and Caustic Soda Industry Report Industry Investment Rating Not provided Core View The report presents the price, supply - demand, and inventory situation of PVC and caustic soda. Caustic soda's supply is expected to increase, but there may be support from supply reduction due to enterprise overhauls. PVC's supply pressure is large with new capacity release, and downstream demand has no obvious improvement [7][12].
