Report Summary 1. Report Industry Investment Rating No industry investment rating information is provided in the given content. 2. Core Views of the Report - **Steel**: The demand for steel in the peak season is not strong, with marginal improvement in building material apparent demand. There is a cost - support due to pre - National Day furnace charge replenishment, but high building material production raises concerns for the distant market. Futures unilateral trading lacks strong rebound drive, and it's recommended to wait and see. For basis - stage buying hedging positions, consider rolling profit - taking before the National Day [2]. - **Silicon Iron and Manganese Silicon**: Market sentiment has improved, but there are hidden concerns in the fundamentals. The industry has turned from loss to profit, supply is increasing, and large - scale production cuts are unlikely. With the arrival of the peak season, there are risks of decreased iron - water and electric - furnace operation, and high inventory needs to be digested [3][5]. - **Coking Coal and Coke**: The spot prices are rising, and with domestic policy expectations and overseas interest - rate cuts, there is strong bottom support. Before the National Day, it's advisable to go long on dips, but also pay attention to taking profits at high prices [6]. - **Iron Ore**: During the replenishment period, there is support for iron ore prices, but the upward space depends on the steel demand. Long - term, it's recommended to go long on dips [7]. 3. Summary by Related Categories Futures Market - **Prices and Changes on September 19**: - **Far - month Contracts**: RB2605 closed at 3232 yuan/ton, up 24 yuan (0.75%); HC2605 at 3384 yuan/ton, up 7 yuan (0.21%); I2605 at 786 yuan/ton, up 6 yuan (0.77%); J2605 at 1883 yuan/ton, up 29.5 yuan (1.59%); JM2605 at 1334 yuan/ton, up 31.5 yuan (2.42%) [1]. - **Near - month Contracts**: RB2601 closed at 3172 yuan/ton, up 23 yuan (0.73%); HC2601 at 3374 yuan/ton, up 6 yuan (0.18%); I2601 at 807.5 yuan/ton, up 6.5 yuan (0.81%); J2601 at 1738.5 yuan/ton, up 13 yuan (0.75%); JM2601 at 1232 yuan/ton, down 16.5 yuan (-1.36%) [1]. - **Spreads and Ratios**: - **Cross - month Spreads**: RB2601 - 2605 was - 60 yuan/ton, down 3 yuan; HC2601 - 2605 was - 10 yuan/ton, up 3 yuan; I2601 - 2605 was 21.5 yuan/ton, unchanged; J2601 - 2605 was - 144.5 yuan/ton, down 5.5 yuan; JM2601 - 2605 was - 102 yuan/ton, down 10 yuan [1]. - **Other Ratios**: The coil - to - rebar spread was 202 yuan/ton, down 5 yuan; the rebar - to - ore ratio was 3.93, down 0.01; the coal - to - coke ratio was 1.41, down 0.01; the rebar disk profit was - 87.38 yuan/ton, down 2.13 yuan; the coking disk profit was 99.94 yuan/ton, down 8.41 yuan [1].

Report on the Rubber Industry 1. Investment Rating No investment rating provided in the report. 2. Core View The report anticipates that rubber prices will oscillate weakly in the short term, with the 01 contract trading in the range of 15,000 - 16,500. The supply side is affected by the rainy season and typhoons in the producing areas, and the expected increase in raw material output in the future suppresses the raw material prices. The cost support has weakened, and the pre - holiday inventory replenishment of downstream tire factories is basically completed, so the natural rubber inventory is unlikely to see a significant reduction. On the demand side, although some enterprises are short of goods, the overall sales performance is below expectations, and some enterprises may control production flexibly. As the holiday approaches, the risk - aversion sentiment of funds increases, and the macro - sentiment of commodities weakens [1]. 3. Summary by Directory Spot Price and Basis - The price of Yunnan state - owned standard rubber (SCRWF) in Shanghai decreased by 100 yuan to 14,700 yuan, a decline of 0.68%. The basis of whole - milk rubber decreased by 65 to - 835. - The price of Thai - standard mixed rubber decreased by 250 yuan to 14,750 yuan, a decline of 1.67%. The non - standard price difference decreased by 215 to - 785, a decline of 37.72%. - The FOB intermediate price of cup rubber in the international market decreased by 0.60 Thai baht per kilogram to 51.05 Thai baht per kilogram, a decline of 1.16%. The FOB intermediate price of glue in the international market increased by 0.10 to 56.30, an increase of 0.18% [1]. Monthly Spread - The 9 - 1 spread decreased by 15 to 15, a decline of 50.00%. The 1 - 5 spread decreased by 10 to 5, a decline of 66.67%. The 5 - 9 spread increased by 25 to - 20, an increase of 55.56% [1]. Production and Consumption Data - In July, Thailand's production was 421,600 tons, an increase of 6,700 tons or 1.61% compared with the previous month. Indonesia's production was 197,500 tons, an increase of 21,300 tons or 12.09%. India's production was 45,000 tons, a decrease of 1,000 tons or 2.17%. China's production was 101,300 tons, a decrease of 1,300 tons [1]. - The weekly operating rate of semi - steel tires for automobiles was 73.66%, an increase of 0.20 percentage points.

The factory - warehouse futures inventory of natural rubber on the Shanghai Futures Exchange decreased by 1,411 tons to 44,553 tons, a decline of 3.07% [1]. Report on the Glass and Soda Ash Industry 1. Investment Rating No investment rating provided in the report. 2. Core View - **Soda Ash**: The fundamental problem of over - supply still exists. Although the manufacturers' inventory has decreased recently, the inventory has actually been transferred to the middle and lower reaches, and the trade inventory continues to rise. The weekly production remains high, and the over - supply still exists compared with the current rigid demand. In the medium term, there is no expectation of a significant increase in downstream production capacity, so the demand for soda ash will continue the previous rigid - demand pattern. If there is no actual production capacity withdrawal or load reduction, the inventory will be further pressured. It is recommended to short on rallies [3]. - **Glass**: The spot market has good transactions, and the inventory has decreased this week. However, the inventory of some middle - stream enterprises in some regions remains high. The deep - processing orders have improved seasonally but are still weak, and the operating rate of low - emissivity (Low - E) glass is continuously low. In the long - term, the real - estate cycle is at the bottom, and the completion volume is shrinking. The industry needs to clear production capacity to solve the over - supply problem. It is necessary to track the implementation of regional policies and the inventory - replenishment performance of the middle and lower reaches during the "Golden September and Silver October" [3]. 3. Summary by Directory Price and Spread - **Glass**: The price of glass 2505 increased by 15 yuan to 1343 yuan, an increase of 1.13%.

The 05 basis decreased by 15 to - 193, a decline of 8.43%. - **Soda Ash**: The price of soda ash 2505 increased by 7 yuan to 1407 yuan, an increase of 0.50%. The price of soda ash 2509 increased by 12 yuan to 1454 yuan, an increase of 0.86%. The 05 basis decreased by 7 to - 107, a decline of 7.00% [3]. Supply - The soda ash mining rate decreased by 2.02 percentage points to 85.53%. The weekly production of soda ash decreased by 15,000 tons to 745,700 tons, a decline of 2.02%. The daily melting volume of float glass decreased by 1,000 tons to 159,500 tons, a decline of 0.47%. The daily melting volume of photovoltaic glass remained unchanged at 89,290 tons [3]. Inventory - The glass inventory decreased by 675,000 tons to 60.908 million tons, a decline of 1.10%. The soda ash factory - warehouse inventory decreased by 42,000 tons to 1.7556 million tons, a decline of 2.33%. The soda ash delivery - warehouse inventory increased by 59,000 tons to 614,900 tons, an increase of 10.69% [3].

The year - on - year growth rate of construction area was 0.05%, a decrease of 2.43 percentage points. The year - on - year growth rate of completion area was - 0.22%, a decrease of 0.03 percentage points. The year - on - year growth rate of sales area was - 6.55%, a decrease of 6.50 percentage points [3]. Report on the Log Industry 1. Investment Rating No investment rating provided in the report. 2. Core View As the "Golden September and Silver October" traditional peak season approaches, it is necessary to observe whether the shipment volume improves significantly. The current average daily shipment volume is still below 70,000 cubic meters. The price below 800 yuan per cubic meter has a high "receiving value". In the current pattern of "weak reality and strong expectation", it is recommended to go long on dips [4]. 3. Summary by Directory Futures and Spot Prices - The price of log 2511 increased by 3.5 yuan to 805 yuan per cubic meter, an increase of 0.44%. The price of log 2601 increased by 2 yuan to 818.5 yuan per cubic meter, an increase of 0.24%. The price of log 2603 increased by 1 yuan to 825 yuan per cubic meter, an increase of 0.12%. The price of log 2605 remained unchanged at 828 yuan per cubic meter [4]. - The 11 - 01 spread decreased by 15 to - 15. The 11 - 03 spread increased by 2.5 to - 20. The 11 - contract basis decreased by 3.5 to - 55. The 01 - contract basis decreased by 66.5 to - 68.5 [4].

Report on the Industrial Silicon Industry 1. Investment Rating No investment rating provided in the report. 2. Core View From a fundamental perspective, from September to October, as the supply of industrial silicon increases, the balance will gradually become looser. The expectation of large - scale production cuts in Sichuan and Yunnan silicon enterprises during the flat - and - low - water period is at the end of October, so the expected surplus in October is more obvious and will narrow again in November. At the same time, the increase in production costs in the southwest during the flat - and - low - water period raises the average industry cost, giving positive sentiment to the market. It is expected that the industrial silicon price will continue to lack upward driving force in the short term and may turn to oscillation, with the main price fluctuation range between 8,000 - 9,500 yuan per ton. It is necessary to pay attention to the production - cut rhythm of silicon - material enterprises and Sichuan and Yunnan industrial silicon enterprises in the fourth quarter [5]. 3. Summary by Directory Spot Price and Basis - The price of East China oxygen - passing SI5530 industrial silicon remained unchanged at 8,350 yuan. The basis decreased by 400 to 45, a decline of 89.89%. - The price of East China SI4210 industrial silicon remained unchanged at 9,600 yuan. The basis decreased by 97 to - 202, a decline of 380.95%. - The price of Xinjiang 99 - silicon remained unchanged at 8,800 yuan. The basis decreased by 400 to 295, a decline of 57.55% [5]. Monthly Spread - The 2510 - 2511 spread decreased by 35 to - 50, a decline of 233.33%. The 2511 - 2512 spread decreased by 5 to - 390, a decline of 1.30%. The 2512 - 2601 spread increased by 5 to 5. The 2601 - 2602 spread increased by 30 to 10, an increase of 150.00% [5]. Fundamental Data - **Production**: The national industrial silicon production was 385,700 tons, an increase of 47,400 tons or 14.01%.

Report on the Polysilicon Industry 1. Investment Rating No investment rating provided in the report. 2. Core View This week, the industry self - discipline meeting was held again to discuss the self - discipline process. Some leading enterprises have production - cut plans in the future. The increase in downstream prices, the meeting, and the low inventory of some enterprises (the inventory distribution among enterprises is uneven) provide support for the price increase of polysilicon enterprises. Currently, low - price resources in the polysilicon market are scarce and are being snapped up, while high - price resources still face some resistance from downstream. It is expected that the polysilicon market will continue to oscillate in the short term [6]. 3.

1. Report Industry Investment Rating - The strength - weakness analysis of the casting aluminum alloy industry is neutral [2] 2. Core Viewpoints of the Report - This week, the price of casting aluminum alloy showed a volatile and weak trend with a phased decline. With the callback of aluminum prices, the willingness of scrap aluminum traders to ship increased, and the market circulation improved marginally. The operating rate of the recycled aluminum industry continued to rise month - on - month, but there was obvious internal differentiation. The demand continued a mild recovery, and the pre - holiday inventory - building demand of downstream enterprises provided some support for the orders of recycled aluminum plants. It is expected that the price of casting aluminum alloy will maintain a high - level volatile trend [6]. - As of September 19, the inventory of aluminum alloy ingot factories and social inventory increased by 0.09 million tons to 13.22 million tons compared with the previous week, and the inventory pressure remained high. The supply shortage of raw materials persisted, and the domestic automobile sales in the second week of September decreased year - on - year. However, the "trade - in" policy had a prominent effect, and the fourth batch of funds would be issued in October as planned, which was conducive to stabilizing consumer confidence and boosting automobile consumption. With the arrival of "Golden September and Silver October", the automobile sales were expected to improve month - on - month [6]. 3.

Report Summary 1. Investment Rating No investment rating for the industry is provided in the report. 2. Core View The report suggests that the log 11 contract will fluctuate in the range of 800 yuan/cubic meter. The current market shows a pattern of inverted domestic and foreign prices, with the high foreign - market quotes providing cost support while domestic inventory has been declining for multiple weeks. Although it is still the off - season for demand, the "Golden September and Silver October" peak season is approaching, and the contract price is undervalued. It is recommended to lay out long - term positions for the peak - season expectation when the price is low. In the short term, due to the pressure from the price difference between high foreign quotes and weak domestic spot prices, import enthusiasm is suppressed, and the daily inventory withdrawal at ports remains high, leading to marginal improvement in supply and demand. However, since the peak - season demand has not started yet, it is advisable to stay on the sidelines for now [6][22]. 3.
