Some products are affected by factors such as inventory, cost, demand, and policies, and their short - term and medium - term trends vary [2][3][5] Summary by Related Catalogs Olefins - Polyolefins - Propylene futures rose, with controllable enterprise inventories and stable offers. Downstream follow - up was okay, and the trading range was stable [2] - Polyethylene futures rose, but the market was waiting for news, with cost support weakening and supply pressure. Sellers mostly offered small discounts [2] - Polypropylene futures rose. Although the supply pressure decreased due to more upstream maintenance, the demand improvement in the peak season was limited, and the high - level inventory was slowly digested. The supply - demand contradiction may increase, and the price may remain low for a long time [2] Pure Benzene - Styrene - Pure benzene futures prices rebounded above 5500 yuan/ton. The spot price in East China rebounded, and the low - level transactions in Shandong improved. The short - term price may rebound, but the high import volume in the medium term is the main pressure [3] - Styrene futures rose, but there were only expected device shutdowns. The inventory remained high, and the upward price momentum was limited [3] Polyester - PX and PTA rebounded with reduced positions. The short - term price may continue to rebound, mainly depending on oil prices. In the medium term, with the weakening demand and expected inventory accumulation, the strategy is mainly reverse arbitrage [5] - Ethylene glycol rebounded with increased positions. The short - term price has a rebound expectation, but there is still inventory accumulation pressure in the medium term, suggesting shorting at high prices [5] - Short fiber continued to be a bullish allocation. The new production capacity was limited, the inventory was decreasing, and the downstream备货 sentiment was improved [5] - Bottle chip demand weakened, with inventory accumulation and pressure on processing margins. The long - term pressure is over - capacity [5] Coal Chemical Industry - Methanol fluctuated at a low level. The short - term coastal market may fluctuate within a range, and the price may be bullish in the medium - to - long term as the import supply pressure is expected to decrease [6] - Urea futures prices rose slightly. The short - term market is expected to fluctuate strongly within a range, supported by the marginal improvement of supply - demand and coal prices [6] Chlor - Alkali - PVC showed a fluctuating trend. The supply may increase, and it may operate at the bottom range due to weak domestic demand and potential export policy pressure [7] - Caustic soda fluctuated narrowly. The supply fluctuated slightly, and it is recommended to be cautious when shorting due to non - aluminum downstream restocking and a high basis [7] Soda Ash - Glass - Soda ash fluctuated strongly. The supply was still high, and it is recommended to short at high prices after a rebound [8] - Glass fluctuated narrowly. The inventory continued to accumulate, and the downward range is expected to be limited. It is advisable to pay attention to selling out - of - the - money put options [8]

Report Industry Investment Ratings No relevant content provided. Core Views Polyolefins - The supply of PE is increasing steadily, with significant profit improvement, continuous increase in the operating rate, and limited planned maintenance. Overseas inventory clearance at the end of the year also brings impacts, highlighting long - term supply pressure. PP's valuation has been significantly repaired due to the sharp decline in propane and crude oil. Although there are more recent overhauls in PP, the new device commissioning pressure in October is large, and the demand side lacks bright performance. The supply - demand structure of polyolefins is loose, and the upside space of the 01 contract is limited. Overall, the macro - environment is pessimistic, and the prices of PP and PE face pressure [2]. Methanol - At the port, due to sanctions, some warehouses do not accept sanctioned vessels, increasing the willingness to hold spot goods. Coupled with supply - side disturbances, the port basis has strengthened significantly. Overseas production has declined, and some devices have stopped. In late October, attention should be paid to the expected supply reduction caused by overseas gas restrictions. Inland supply has a certain bottom - support for prices due to a relatively healthy inventory structure. The demand side is weak. Overall, the price may continue to fluctuate under the supply - demand game, and attention should be paid to the port de - stocking rhythm and the implementation effect of overseas gas - restriction expectations [4]. Benzene - Styrene - For pure benzene, although there are device overhauls, there are also new production capacity commissioning expectations, and the domestic supply is expected to remain at a relatively high level. The downstream demand support is limited, and the inventory in East China ports may continue to decline. The price drive is weak in October. For styrene, under the double pressure of inventory and industry profit, some devices are under overhaul, but new devices are about to be commissioned, and the overall supply will remain high. The demand side support is also limited, and the price drive is weak. In the short - term, the price is still under pressure [6]. Polyester Industry Chain - For PX, the supply has shrunk compared to expectations due to unexpected overhauls or load reductions of some devices, while the demand has increased. However, overall, the supply - demand is still weak, and the price is in a weak oscillation. For PTA, the spot basis continues to weaken, but the downward space is limited. The absolute price is also in a weak oscillation. For short - fiber, the price is supported in the short - term, but the cost - side support is weak. For bottle - chips, it is likely to enter a seasonal inventory accumulation period, and it follows the cost - side fluctuations. For ethylene glycol, the domestic supply is abundant, and it is expected to accumulate inventory in October, with the upper price limit under pressure [7]. PVC and Caustic Soda - For caustic soda, the demand support from the aluminum industry is weak in the short - term, but there may be long - term demand support. The supply is increasing in the short - term, and the price is weak. For PVC, the supply - demand pressure is large, the fundamental contradiction is difficult to resolve, and the price is weak. The cost - side provides bottom support, and short - term short positions can stop profit [8].

1. Report Industry Investment Ratings - No industry investment ratings are provided in the reports. 2. Core Views Polyester Industry - PX: Short - term drive is limited, with weak oscillations. Supply is expected to contract, but overall remains weak. Suggest to wait and see, focus on Brent crude oil support at $60/barrel, and conduct month - spread reverse arbitrage [1]. - PTA: Short - term drive is limited, with weak oscillations. Spot basis has weakened, but the downward space is limited. Suggest to wait and see, focus on Brent crude oil support at $60/barrel, and treat TA1 - 5 with rolling reverse arbitrage [1]. - Ethylene Glycol (MEG): Supply is abundant, with expected inventory accumulation in October and high accumulation in November - December. Suggest to short EG01 at high prices, hold the seller of call option EG2601 - C - 4250, and conduct EG1 - 5 reverse arbitrage at high prices [1]. - Short - fiber: Supply is at a high level, and terminal demand in Q4 is expected to be weak. Prices are supported in the short - term due to low inventory. Suggest the same strategy as PTA for single - side trading, and shrink the processing margin when it is above 1000 in the range of 800 - 1100 [1]. - Bottle - chip: Entering the seasonal inventory accumulation period, prices fluctuate with the cost side. Suggest the same strategy as PTA for PR single - side trading, and expect the main - contract processing margin to fluctuate between 350 - 500 yuan/ton [1]. Pure Benzene - Styrene Industry - Pure Benzene: Overall supply and demand in October are expected to be loose, with weak price drive. Suggest BZ2603 to oscillate following styrene and oil prices [2]. - Styrene: Supply will remain high, and demand support is limited. Prices are still under pressure in the short - term. Suggest to short EB12 on price rebounds [2]. Chlor - Alkali Industry - Caustic Soda: Short - term supply is increasing, and demand support is weak, with prices tending to be weak. In the medium - to - long - term, there is demand support. Suggest to short in the short - term and track downstream restocking [3]. - PVC: Supply and demand pressure is high, and the contradiction is difficult to resolve. Cost provides bottom support. Suggest to stop short - selling and wait for changes in demand [3]. Methanol Industry - Methanol: Prices may continue to oscillate. Focus on overseas device stability, customs clearance efficiency of sanctioned vessels, and actual arrival. Pay attention to port inventory reduction and overseas gas - limiting expectations [4]. Polyolefin Industry - LLDPE and PP: Supply pressure is prominent in the medium - to - long - term, and demand lacks bright spots. The 01 - contract upside is limited. Prices are under pressure due to macro - environment, cost, and supply - demand factors [6]. 3.
