1. Report Industry Investment Ratings - Urea: ★★★ (more bullish) [1] - Methanol: ★★★ (more bullish) [1] - Pure Benzene: ★★★ (more bullish) [1] - Styrene: ★★★ (more bullish) [1] - Propylene: ★★★ (more bullish) [1] - Plastics: ★★★ (more bullish) [1] - PVC: ★★★ (more bullish) [1] - Caustic Soda: ★★★ (more bullish) [1] - PX: ★★★ (more bullish) [1] - PTA: ★★★ (more bullish) [1] - Ethylene Glycol: ★★★ (more bullish) [1] - Short - fiber: ★★★ (more bullish) [1] - Glass: ★★★ (more bullish) [1] - Soda Ash: ★★★ (more bullish) [1] - Bottle Chip: ★★★ (more bullish) [1] 2. Core Views - The chemical market shows complex trends with different product performances. Some products are affected by factors such as device maintenance, demand changes, and supply - demand imbalances [2][3][5]. - There are differences in the performance of the spot and futures markets, and the basis has changed in some products [2][3]. - The supply - demand relationship is a key factor affecting prices, with some products facing supply - demand contradictions [2][3][5] 3. Summary by Relevant Catalogs Olefins - Polyolefins - Propylene prices continued to rise due to early - started planned maintenance of a device in Dongying during the National Day holiday and the gradual recovery of some downstream demand. However, the futures price fell on the first trading day after the holiday, resulting in a divergence between the spot and futures markets and an enlarged basis [2]. - Polyolefins faced a situation of weak peak - season demand, mainly with rigid procurement. The large - scale release of new production capacity led to a significant increase in domestic output, resulting in prominent supply - demand contradictions. There was inventory accumulation during the holidays, and there was obvious pressure to reduce inventory after the holidays, causing price pressure [2] Pure Benzene - Styrene - During the National Day, the oil price dropped, and the pure benzene futures once fell below 5700 yuan/ton in the morning session and then rebounded with the oil price in the afternoon. The spot price in East China was weak, the shipment in Shandong was dull, and Sinopec's listed price remained stable. The device operation rate continued to rise, and the port inventory decreased. However, high imports and expected demand decline continued to drag down the market [3]. - The main contract of styrene futures closed slightly lower, with the overall center of gravity moving down along the 5 - day moving average. The oil price during the holiday was basically the same as before the holiday, having limited impact on the cost of styrene. The demand was weak during the peak season, and the supply increased significantly due to the expansion of production capacity. The inventory of styrene has been significantly higher year - on - year since this year and has shown a trend of oscillating inventory accumulation after June, suppressing the price [3] Polyester - During the holiday, the overseas oil price dropped, causing the prices of PX and PTA to weaken in the morning and then recover with the rebound of the oil price in the afternoon. The operation rate of PX continued to increase. Hengli Dalian's PTA carried out maintenance, and some East China devices reduced their loads due to reasons. In the short term, PX was under pressure, and the PTA link repaired its profit. However, in the future, the PX of Wushi Petrochemical plans to carry out maintenance, and the polyester load is expected to remain stable. The near - term supply - demand pattern of upstream raw materials is okay, and attention should be paid to terminal orders and raw material restocking. In mid - to late October, the downstream demand is expected to gradually weaken, and the supply - demand situation will still be under pressure in the long - term [5]. - The domestic operation rate of ethylene glycol increased significantly, and the port inventory accumulated significantly during the holiday, with a weak fundamental situation. The main futures price once approached the 4100 yuan/ton mark. In the medium - term, with the mass production of new devices and the weakening of future demand, the supply - demand situation will gradually weaken in the fourth quarter, and the 1 - 5 spread is under downward pressure [5]. - The new production capacity of short - fiber is limited, and the operation rate is at a high level. The terminal weaving and dyeing industries increased their operation rates, and the recovery of peak - season demand boosted the short - fiber industry. It is recommended to be long in the short - term, and attention should be paid to downstream orders and short - fiber inventory [5]. - The operation rate of bottle chips increased, but after the long holiday, with the cooling weather, the demand is expected to weaken. Overcapacity is a long - term pressure, and the processing margin is under continuous pressure [5] Coal Chemical Industry - The methanol futures price dropped significantly. During the holiday, the import volume remained high, and the port inventory continued to accumulate. The capacity utilization rate of domestic methanol devices increased. Before the holiday, inland olefin enterprises carried out centralized external procurement, and enterprises had sufficient pending orders, but the order execution was slowed down due to logistics restrictions, and the inventory of production enterprises increased slightly. Imports are expected to remain sufficient, and the port is expected to continue to accumulate inventory. The near - term situation is weak, while the far - month outlook is relatively strong. Attention should be paid to factors such as macro - sentiment and overseas device changes [6]. - During the National Day holiday, urea production enterprises significantly accumulated inventory, with high supply and great pressure on enterprise shipments. Affected by factors such as weather and logistics, the downstream demand was insufficient. Export orders were being shipped, and the port inventory decreased. Although India issued a new round of urea tenders, planning to import 2 million tons, the export window period may have ended, and the short - term boost to the market is limited. The pattern of loose domestic supply - demand of urea is difficult to change, and attention should be paid to possible policy adjustments and their impact on market sentiment [6] Chlor - Alkali Industry - The main contract of PVC dropped. During the holiday, the downstream demand weakened, the supply was at a high level, and the inventory increased significantly. After the end of maintenance and the release of new production capacity, the supply pressure was high. The downstream's intention to stock up was not high, and the industry continued the inventory - accumulation mode. The chlor - alkali integration still had profits, and the cost support was not obvious. PVC may show a weak - oscillating trend [7]. - The caustic soda futures dropped significantly. There was still the phenomenon of vehicle detention by downstream buyers, and the purchase price may be further reduced, with the inventory increasing compared with the previous period. There are small - scale maintenance plans for caustic soda in North China and East China in October, and the supply is still under high - pressure operation due to remaining profits. The liquid - caustic soda inventory of alumina plants in Shanxi and Henan is high, and the downstream profit is shrinking, with resistance to high prices. The weak - reality pattern continues, but the strong expectation of possible restocking demand before the future downstream alumina production cannot be falsified. It is recommended to wait and see [7] Soda Ash - Glass - The price of soda ash futures was weakly operating. Before the holiday, the inventory was mainly reduced, and it increased after the holiday. The rigid demand for heavy soda was stable. The production capacity of float glass and photovoltaic glass has been stable recently. The inventory of the photovoltaic industry has changed from decreasing to increasing, and it is expected that the ignition speed will slow down in the future, with limited incremental rigid demand for heavy soda. There are few maintenance plans in October, and the industry currently has little operating pressure, with high - pressure supply. The long - term pattern of supply - demand surplus remains unchanged, and opportunities to short at high prices should be sought, but caution should be exercised near the cost [8]. - The price of glass futures fluctuated narrowly. During the holiday, downstream enterprises had holidays, and the production and sales were insufficient, with seasonal inventory accumulation in the industry. Some regions raised their quoted prices. The daily melting volume was oscillating at a relatively high level. The processing orders improved but were still insufficient on a month - on - month basis, and some engineering orders increased. The situation of whether Shahe will centrally use Zhengkang's deep - processed gas should be continuously tracked. If the production - capacity reduction does not actually occur, the market may return to weak - reality trading, but with the current low valuation, the decline is expected to be limited. A low - buying strategy near the cost can be considered in the future [8]

Core Views of the Report - The trading logic of iron ore has increased uncertainty, with short - term support under supply - side interference. The follow - up focus is on the actual impact on the supply side and October steel demand [2]. - In October, the supply of coking coal in China is expected to run stably, with limited increase. Coke supply - demand contradiction is not significant, and its trend follows coking coal. Attention should be paid to the implementation of the "anti - involution" policy [2]. - For rebar, the futures price has a low static valuation. The supply side may shrink, and the focus is on the demand recovery in October. The price needs to see rapid post - festival inventory reduction to stabilize [2]. - The glass market has short - term support from the replenishment market, but the demand is difficult to improve fundamentally. The supply - demand is basically balanced, and the follow - up should pay attention to production and policy changes [2]. - The stock index market is volatile, with an optimistic upward outlook. Stock index long positions should maintain the current position, while Treasury bond long positions should be held lightly [4]. - The logic for the rise in gold prices has not completely reversed. It is expected to show strong - biased oscillation, affected by the Fed's interest - rate policy and geopolitical risks [4][6]. - Logs are expected to oscillate in a range, with supply - side pressure not significant and an increase in daily outbound volume [6]. - Pulp prices are expected to consolidate at the bottom, affected by cost support and demand factors [6]. - The oil and fat market continues the range - oscillation pattern, with significant differentiation among varieties. Attention should be paid to Brazilian soybean sowing and Malaysian palm oil production and sales [6]. - Bean meal prices are expected to move downward in the short term, affected by supply and demand factors such as new soybean listings and changes in Chinese demand [6][7]. - Live pig prices are expected to oscillate slightly downward in the short term, with sufficient supply and weak downstream demand [7]. - Natural rubber prices may show wide - range oscillation, affected by supply, demand, and inventory factors [9]. - The prices of PX, PTA, MEG, PR, and PF are mainly affected by cost, supply, and demand factors, with different trends [9]. 3. Summaries According to Relevant Catalogs Black Industry - **Iron ore**: During the long holiday, the Singapore Exchange iron ore swaps rose slightly. There are new concerns about supply, and the short - term supply - side interference provides support. The follow - up core is steel demand in October [2]. - **Coking coal and coke**: In October, domestic coking coal supply is expected to be stable, with production lower than last year. Coke's first - round price increase was implemented, and the second - round basically failed. Coke supply - demand contradiction is not large, and it follows coking coal [2]. - **Rolled steel and rebar**: During the long holiday, Tangshan billet prices were stable. Rebar futures have a low valuation, and the supply side may shrink. The focus is on demand recovery in October, and the price needs rapid post - festival de - stocking [2]. - **Glass**: Market sentiment was boosted by news, and prices rose. Supply was stable last week, and there was short - term support from replenishment. However, long - term demand is suppressed by the real estate adjustment [2]. - **Soda ash**: Although the report mentions it in the context, there is no specific in - depth analysis other than the overall "oscillation" rating [2]. Financial and Precious Metals - **Stock Index Futures/Options**: The market is volatile. The overall upward outlook is optimistic, and stock index long positions should maintain the current position [4]. - **Treasury bonds**: Market interest rates are volatile, and Treasury bond trends are weak. Treasury bond long positions should be held lightly [4]. - **Gold and Silver**: Gold's pricing mechanism is changing. The logic for the rise has not reversed, and it is expected to show strong - biased oscillation, affected by the Fed's policy and geopolitical risks [4][6]. Light Industry - **Logs**: Port daily shipment volume increased, and supply is expected to be tight. The cost support is enhanced, and it is expected to oscillate in a range [6]. - **Pulp**: Spot prices fluctuated. Cost support is enhanced, but demand improvement is uncertain. It is expected to consolidate at the bottom [6]. - **Double - offset paper**: The spot price is stable. Production is relatively stable, and demand is expected to improve, but prices are expected to oscillate [6]. Oil and Fats - **Soybean oil, Palm oil, Rapeseed oil**: The oil and fat market shows a wide - range oscillation pattern. There are differences among varieties, affected by factors such as Argentine exports, biodiesel, and seasonal production [6]. - **Bean meal, Rapeseed meal**: Although there is some support from US domestic demand, new soybean listings and Brazilian production potential bring supply pressure. Prices are expected to move downward [6][7]. Agricultural Products - **Live pigs**: The average trading weight is declining, and supply is sufficient. Downstream demand is weak, and prices are expected to oscillate slightly downward [7]. Soft Commodities and Polyester - **Rubber**: Supply - side pressure in Yunnan has decreased, while Hainan's output is lower than expected. Demand has improved slightly, and inventory is decreasing. Prices may show wide - range oscillation [9]. - **PX, PTA, MEG, PR, PF**: These products are mainly affected by cost, supply, and demand factors. Their prices show different trends such as oscillation, wait - and - see, etc. [9]

Some products are facing supply pressure and weak demand, while others have certain support from demand but also face future uncertainties [2][3][5] Summary by Category Olefins - Polyolefins - Olefin futures' main contracts fluctuated narrowly. Supply is controllable as restarting devices are not in place, and downstream demand provides some price support [2] - Polyolefin futures' main contracts also fluctuated narrowly. Polyethylene maintenance decreased with increased domestic production, and downstream has pre - holiday stocking demand but faces post - holiday de - stocking pressure. Polypropylene prices are under pressure due to multiple factors such as demand differentiation, supply pressure, and high inventory [2] Pure Benzene - Styrene - Pure benzene oscillated downward. Although the current fundamental situation is okay with port inventory decreasing and spot price being relatively firm, high import volume and expected demand decline drag the market [3] - Styrene futures' main contracts fluctuated narrowly. Cost - end oil price provides support, but high inventory suppresses the price [3] Polyester - PX's strong expectation weakened, and PTA's profitability is still poor. Although the pre - holiday stocking in the polyester yarn industry has reduced inventory pressure, post - holiday demand is expected to weaken, and the supply - demand situation remains under pressure [5] - Ethylene glycol's domestic operation decreased slightly, and port inventory is low. However, new device trials and weakening demand may lead to a weak supply - demand situation in the fourth quarter [5] - Short - fiber's new capacity is limited, and inventory decreased. The pre - holiday stocking has fulfilled the positive expectation. Bottle chips showed a short - term strong trend due to typhoon - affected device shutdown, but long - term over - capacity is a pressure [5] Coal Chemical Industry - Methanol's main contract oscillated. Port inventory is expected to increase after the holiday, and the market is expected to be weak [6] - Urea prices increased slightly, but downstream follow - up is cautious. The domestic supply - demand situation is loose, and attention should be paid to policy adjustments [6] Chlor - Alkali - PVC oscillated weakly with high supply and high inventory. Domestic downstream pre - holiday stocking intention is low, and foreign demand is weak [7] - Caustic soda's futures price oscillated under the weak situation. Although there is an expectation of downstream stocking before alumina production, the current supply is high [7] Soda Ash - Glass - Soda ash weakened. The industry is de - stocking, and the downstream pre - holiday stocking is nearly over. The long - term supply is in excess [8] - Glass prices fell from a high level. Some manufacturers plan to increase prices, and attention should be paid to downstream restocking sentiment [8]
