1. Report Industry Investment Rating - The report does not provide an overall industry investment rating. However, for each specific energy and chemical product, the short - term outlook is mainly "oscillating" [1][3][5][6][8]. 2. Core Viewpoints - Overall, the current energy and chemical market is affected by multiple factors such as supply - demand relationships, international policies, and crude oil price trends. Most product prices are expected to show oscillating trends, with some facing downward pressure due to factors like increased supply or geopolitical influences [1][3][5][6][8]. 3. Summary by Relevant Catalogs 3.1 Research Views - **Crude Oil**: On Thursday, oil prices declined. WTI November contract closed down $0.81 to $57.46 per barrel, a 1.39% drop; Brent December contract closed down $0.85 to $61.06 per barrel, a 1.37% drop; SC2511 closed at 435.1 yuan per barrel, down 8.1 yuan per barrel, a 1.83% decline. U.S. crude oil inventories increased by 3.5 million barrels to 423.8 million barrels last week, and EIA crude oil production reached a record high of 13.64 million barrels per day. India may reduce Russian oil imports. Overall, oil prices will continue to decline under supply - demand pressure [1]. - **Fuel Oil**: On Thursday, the main fuel oil contract FU2601 on the Shanghai Futures Exchange rose 0.94% to 2,694 yuan per ton; the low - sulfur fuel oil contract LU2512 rose 0.03% to 3,159 yuan per ton. Singapore and Fujeirah fuel oil inventories increased. Short - term high - sulfur fundamentals may be slightly stronger than low - sulfur, but under the pressure of Trump's new tariffs on oil prices, the absolute prices of high - and low - sulfur fuel oils will oscillate weakly [3]. - **Asphalt**: On Thursday, the main asphalt contract BU2511 rose 0.55% to 3,250 yuan per ton. This week, domestic asphalt shipments increased, but the capacity utilization rate of modified asphalt enterprises decreased. There is still some construction rush expectation after the holiday, but previous significant production increases may suppress prices. Under the pressure of Trump's new tariffs on oil prices, asphalt will oscillate weakly in the short term, with a smaller decline than crude oil and fuel oil [3]. - **Polyester**: TA601, EG2601, and PX futures contracts all rose on Thursday. The production and sales of polyester yarn in Jiangsu and Zhejiang were differentiated, with an average of about 60%.

Polyester chain prices will fluctuate with crude oil prices in the short term, and cost reduction may stimulate polyester factories' restocking demand [3][5]. - **Rubber**: On Thursday, the main rubber contracts RU2601, NR, and BR all rose. The main rubber - producing areas are in normal tapping season. The basis of the 20 - type rubber strengthened, and the inventory of downstream tire products is high. The price of natural rubber will oscillate [5]. - **Methanol**: On Thursday, methanol spot prices showed different trends. The domestic supply has recovered, and overseas Iranian devices have resumed production, but future production increases are limited due to winter gas restrictions. It is recommended to pay attention to the strategy of going long on methanol and short on polyolefins and the positive spread strategy between months [6]. - **Polyolefins**: On Thursday, polyolefin prices showed different trends. The short - term supply will remain high, and the marginal increase in demand in October will gradually decline. With the weakening of crude oil prices, polyolefin prices will be weak [6]. - **Polyvinyl Chloride (PVC)**: On Thursday, PVC prices in different regions showed oscillating trends. The supply remains high, domestic demand has slowed down, and exports are expected to be weak.

1. Investment Ratings No investment ratings for the industries are provided in the reports. 2. Core Views Methanol - The price may continue to fluctuate under the game of supply and demand. Focus on the stability of overseas device operation, the customs - clearance efficiency of sanctioned vessels, and actual arrival performance. Pay attention to the port destocking rhythm and the implementation effect of overseas gas - limiting expectations [1]. Polyolefins (LLDPE & PP) - The inventory pressure after the holiday is still significant. The supply pressure is prominent in the medium - and long - term, and the demand lacks highlights. The upside space of the 01 contract is limited [5]. Caustic Soda - There is demand support in the medium - and long - term, but it is weak in the short term. It was previously recommended to be bearish, and now the short positions can be temporarily closed as the market stabilizes [8]. PVC - The short - term disk may continue to be under pressure. Although the supply pressure has slightly eased and exports have recovered, the demand in the peak season is weak. Pay attention to cost support and downstream demand performance [8]. PX - The supply and demand are expected to be weak in the fourth quarter. It will mainly fluctuate at a low level in the short term. It is recommended to wait and see and look for short - selling opportunities on rebounds, and mainly conduct reverse spreads on the monthly spread [9]. PTA - The short - term drive is limited, and it will mainly fluctuate at a low level. It is recommended to wait and see TA, pay attention to the support around 4500, and conduct rolling reverse spreads on TA1 - 5 [9]. Ethylene Glycol - It is expected to accumulate inventory in October, and the supply - demand structure is weak in the far - month. It is recommended to short EG01 on rallies, hold the seller of the out - of - the - money call option EG2601 - C - 4350, and conduct reverse spreads on EG1 - 5 [9]. Short Fibers - The absolute price is still under pressure in the short term, but it is relatively strong compared to raw materials due to low inventory. It is recommended to have the same strategy as PTA for the unilateral position, and widen the processing margin at a low level [9]. Bottle Chips - It is likely to enter the seasonal inventory accumulation channel. PR follows the cost end, and the processing margin improves in the short term. It is recommended to have the same strategy as PTA for the unilateral position, and the main contract processing margin is expected to fluctuate between 350 - 500 yuan/ton [9]. Pure Benzene - The overall supply and demand in October are expected to be loose, and the price drive is weak. BZ2603 follows the fluctuations of styrene and oil prices [10]. Styrene - The supply - demand is expected to be loose, and the price is still under pressure in the short term. EB11 should be treated as a short - selling opportunity on rebounds [10]. 3.
