1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - PX: Last week, PXN was slightly compressed. Due to weak fundamentals and limited by PTA processing fees, the overall valuation was difficult to expand. The price rose passively following crude oil. Currently, PX load remains high, with many PTA downstream overhauls and a low overall load center. The expectation of new PTA device production suppresses PTA processing fees, making it difficult to continuously reduce PX inventory. There is currently no driving force, and PXN is difficult to expand actively due to PTA processing fees. The valuation is at a neutral level, mainly following crude oil fluctuations. There is a risk of negative feedback under the reality of low PTA processing fees. Short - term observation is recommended [11]. - PTA: Last week, PTA processing fees continued to be compressed in a weak pattern. Even though terminal data improved significantly, it was essentially due to the difficult - to - relieve pressure expectation on the supply side. Therefore, this week's rebound was mainly a passive rebound following costs. In the future, the short - term supply - side overhaul volume will decrease, turning to slight inventory accumulation. Due to the weak long - term pattern expectation, processing fees are difficult to expand. On the demand side, the inventory and profit pressure of polyester chemical fibers are low, and the load is expected to remain high. However, due to inventory pressure and the off - season of downstream bottle chips, the bottle chip load is difficult to increase, and the probability of further boosting the polyester load is small. The improved terminal data is difficult to be reflected in the already high polyester chemical fiber load. In terms of valuation, PXN is continuously suppressed by continuous PTA overhauls under low processing fees. There is even a risk of negative feedback under the reality of low PTA processing fees. Short - term observation is recommended [12]. - MEG: In terms of industrial fundamentals, the load of domestic and overseas devices is at a high level, the domestic supply is high, and the import volume has rebounded, with ports turning to inventory accumulation. In the medium term, as imports arrive in a concentrated manner and the domestic load is expected to remain high, coupled with the gradual commissioning of new devices, inventory accumulation is expected to continue in the fourth quarter. The current valuation is still relatively high compared to the same period, and there is pressure for continuous compression in the weak pattern. It is recommended to short on rallies [13]. 3.

1. Report Industry Investment Rating There is no information provided about the report industry investment rating in the given content. 2. Core View of the Report The stainless - steel market rebounded last week, but its actual impact on the spot market was limited. Although the crude steel production continued to grow, the actual output was lower than the initial production plan due to some enterprises' production reduction and control strategies. As the traditional "Golden September and Silver October" peak season is coming to an end, the terminal demand release is lower than expected, and the market activity remains low. Downstream purchases are mainly for rigid needs, with low acceptance of high - priced resources, and most transactions are concentrated on low - priced resources. In terms of raw materials, the prices of high - nickel iron, high - carbon ferrochrome, and molybdenum iron are generally under pressure, weakening the cost support for stainless steel to varying degrees. Under the dual pressure of weakened cost support and a loose supply - demand structure, the stainless - steel market is expected to continue its weak operation in the short term [11][12]. 3.

1. Report Industry Investment Rating No relevant content provided. 2. Core Views Glass - The domestic 5mm float glass market continued its downward trend last week, with prices in various regions generally decreasing by 30 - 90 yuan/ton. The market is currently in a situation of strong supply and weak demand, with overall rising enterprise inventories, persistently sluggish downstream demand, and purchases mainly for刚需. There is a lack of substantial positive support. Affected by low - price supplies and rainy weather in some areas during the week, the trading pace further slowed down, and prices were under downward pressure. Although the increase in coal prices in the second half of the week strengthened cost support to some extent, the overall market sentiment remained bearish, and the price rebound momentum was insufficient. In the short term, the market lacks new driving factors and is expected to continue a weak and narrow - range oscillating trend. It is recommended to pay attention to the dynamic of enterprise cold repairs and the marginal changes in the expectation of the "anti - involution" policy [12][13]. Soda Ash - Last week, the prices of light and heavy soda ash in the northwest region decreased slightly. The industry supply continued to operate at a high level. Although the maintenance of individual enterprises provided some support to the local market, the overall production capacity base was large, and the supply pressure remained unchanged. There are still plans for individual devices to start up and resume production in the later stage. On the demand side, the downstream purchasing willingness is low, and they generally adopt a cautious strategy of replenishing inventory on demand and buying at low prices. Manufacturers have few new orders, and the wait - and - see sentiment is strong. Overall, the soda ash market is difficult to reverse the pattern of loose supply and demand in the short term. Prices are expected to remain stable and weak, and the trading center may further decline [56][57]. 3. Summary by Directory Glass 01.

1. Report Industry Investment Rating No relevant content provided. 2. Core View of the Report This week, tin prices rebounded slightly from a low level. Supply remains tight, with the slow resumption of tin mines in the Wa State of Myanmar and insufficient raw materials for smelting enterprises. Although the mining licenses in the Wa State have been approved, the tin ore export volume is still far below the normal level due to the rainy season and slow actual resumption progress, failing to effectively make up for the supply gap. In September 2025, China's imported tin concentrate physical volume decreased significantly compared to the previous month. On the demand side, although the consumption in traditional fields such as consumer electronics and tinplate is slightly weak, the long - term demand expectations brought by emerging fields such as new energy vehicles and AI servers support tin prices. In September, the operating rate of domestic tin solder enterprises showed a slight recovery. Downstream enterprises mainly replenish inventory at low prices. The social inventory of major tin ingots decreased this week. Overall, the tight supply situation supports tin prices, and it is expected that tin prices will remain stable or rebound slightly [11][13]. 3. Summary by Directory 3.1. Weekly Assessment and Strategy Recommendation - **Cost End**: Although the mining licenses in the Wa State of Myanmar have been approved, the resumption progress is slow, and significant recovery of tin ore supply is expected in the fourth quarter. In September 2025, China's imported tin concentrate physical volume was 8,714 tons, a significant decline from the previous month. The import volume from countries such as the Democratic Republic of the Congo has decreased, but the overall volume is at a normal level, only affected by shipping factors. The import volume from Myanmar is increasing, and short - term supply shows signs of improvement. The import volume from other regions and countries remains at the previous level [12]. - **Supply End**: The resumption of tin mines in the Wa State of Myanmar is slow and difficult to increase production before November. The raw material shortage of smelting enterprises in Yunnan still exists, and the processing fee (TC) for 40% grade tin concentrate in Yunnan remains low. In Jiangxi, due to a significant reduction in scrap, the supply of crude tin is insufficient, and the refined tin output continues to be at a low level. The raw material inventory of domestic smelters is generally less than 30 days, and some enterprises carried out maintenance in September, with the capacity utilization rate likely to remain low [12]. - **Demand End**: Although the consumption in traditional fields such as consumer electronics and tinplate is slightly weak, the long - term demand expectations brought by emerging fields such as new energy vehicles and AI servers support tin prices. In the peak season, the operating rate of domestic tin solder enterprises showed a slight recovery in September. Downstream enterprises mainly replenish inventory at low prices. This week, the total social inventory of major tin ingots was 7,743 tons, a decrease of 182 tons from last week [12]. 3.2. Futures and Spot Market No specific analysis content provided, only relevant charts are presented, including the basis of Shanghai tin main contract and the LME tin premium (0 - 3) [19][20]. 3.3. Cost End Tin ore supply is tight in the short term, and processing fees remain at a low level [27]. 3.4. Supply End The resumption of tin mines in the Wa State of Myanmar is slow, and the raw material shortage of smelting enterprises in Yunnan and Jiangxi persists, resulting in a low level of refined tin output and a low capacity utilization rate of domestic smelters [12]. 3.5. Demand End - The year - on - year growth rate of China's semiconductor sales has rebounded slightly, and global semiconductor sales have maintained high growth [45]. - Tin consumption in the tinplate field continues to decline, mainly because aluminum cans have almost completely replaced tinplate cans in the beverage packaging field. The PVC output increased slightly year - on - year in the first half of the year, and PVC stabilizers are a major consumer of tin compounds [56]. - The operating rate of downstream solder enterprises showed a slight recovery in September, and downstream enterprises mainly replenish inventory at low prices [12]. 3.6. Supply - Demand Balance This week, the total social inventory of major tin ingots was 7,743 tons, a decrease of 182 tons from last week [12].

1. Report Industry Investment Rating - Not provided in the given content 2. Core View of the Report - The decline in precious metal prices is more of a "correction in an uptrend" rather than a "trend reversal" based on geopolitical risks, weakening US dollar credit, and the start of the Fed's interest - rate cut cycle.
