Spot News - **Short - fiber**: The decline of short - fiber futures narrowed. Zhejiang and Jiangsu factories' spot quotes remained stable, while those in Fujian dropped by 50. The mainstream quotation of semi - dull 1.4D was 6450 - 6500 for ex - factory or short - distance delivery, with discounts available for negotiation. Affected by the decline in oil prices, low - point price transactions of short - fiber increased in the morning. The mainstream negotiation price of semi - dull 1.4D was in the range of 6150 - 6400. Affected by the cancellation of India's BIS certification, the sales of factories showed high - low differentiation, with an average sales - to - production ratio of 56% by 3:00 pm [2]. - **Bottle - chip**: In the morning, the upstream raw material futures fell weakly, and polyester bottle - chip factories mostly lowered their quotes by 20 - 50 yuan. The trading atmosphere in the polyester bottle - chip market rebounded during the day, but most transactions were concentrated in the previous range. After the futures rose in the afternoon, the market follow - up was limited, and the price gap between different brands was large. Orders from November to January were mostly traded at 5650 - 5750 yuan/ton ex - factory, slightly lower at 5610 - 5640 yuan/ton ex - factory, and slightly higher at 5780 - 5810 yuan/ton ex - factory [2].

1. Report Industry Investment Rating No industry investment rating is provided in the report. 2. Core Viewpoints of the Report - The cancellation of India's BIS certification is beneficial for the export of PTA and filaments, but the new production capacity in India and Indonesia in 2026 may reduce their import volume. The export of filaments may increase by 2 - 30,000 tons per month in 2026 [2]. - The low price of ethylbenzene drives the expectation of blending oil, and the aromatics arbitrage between Asia and America has started, leading to the rise of PX and PTA prices [2]. - The supply of oil from the Middle East, Latin America, and Russia has increased significantly since Q3, with a bearish impact on oil prices. However, market differentiation due to sanctions still exists, and geopolitical and macro - events may affect market sentiment [2]. - For PX, the domestic PX plant load has reached a high level in recent years, and PXN has support but limited rebound space. For TA, there is limited inventory accumulation pressure in November, but it will increase after December. In the long - term, PTA processing fees are expected to improve [2][3][5][6]. - The polyester开工率 is 91.3% (down 0.4% month - on - month), with improved domestic sales orders since late October. The polyester load in November is expected to remain around 91% [3]. - For PF, the spot production profit is 156 yuan/ton (down 26 yuan/ton month - on - month), with high load and low inventory. The processing fee is expected to remain stable. For PR, the bottle - chip processing fee is expected to fluctuate within a range, and attention should be paid to raw material price fluctuations [3][6]. - The strategy is to be cautiously bullish on PX/PTA/PF/PR. The 01 contract has limited upside space due to inventory accumulation pressure, and attention should be paid to the 05 contract in the long - term. There are no cross - variety and cross - period strategies [5][6]. 3.
