Report Summary 1. Report Industry Investment Rating No information provided on the report industry investment rating. 2. Core Views - Overall, the domestic demand for ethylene glycol in the demand side has declined at a moderate pace. After the liberalization of BIS, the export orders for filament have increased significantly. The polyester demand is expected to remain above 91% in November, and the average monthly load in December is expected to be adjusted from 90% to slightly below 91%. Recently, there have been many unexpected incidents in the supply - side devices, and the subsequent inventory accumulation slope has eased. However, the coking coal trading in the cost side has weakened, indicating a reduced concern about the cost side, and the price has continued to break through and decline. In the long - term, the slowdown and delay of inventory accumulation are just rhythm issues, and the pattern of valuation pressure under the expectation of oversupply in supply - demand cannot be reversed. The current expectation of near - end explicit inventory accumulation has been partially fulfilled, and the anti - risk ability against supply - side accidents has also increased. Therefore, the idea of shorting on rallies remains unchanged. In terms of the downward space, the cash flow of the current coal - based marginal ethylene glycol devices has been compressed below the cost line. Considering the start - up situation of coal - based devices, if the valuation continues to be compressed, it is expected to receive strong support from the supply side around 3700. Specifically, for the 01 contract, short positions or selling call options can be considered above 3900 [5]. 3. Summaries According to Relevant Catalogs Polyester Price Range Forecast | Product | Price Range Forecast (Monthly) | Current Volatility (20 - day Rolling) | Current Volatility Historical Percentile (3 years) | | --- | --- | --- | --- | | Ethylene Glycol | 3650 - 4100 | 16.39% | 34.0% | | PX | 6300 - 7100 | 14.77% | 37.9% | | PTA | 4300 - 4900 | 11.91% | 15.7% | | Bottle Chips | 5400 - 6000 | 9.91% | 13.7% | [4] Polyester Hedging Strategy Table - Inventory Management: When the finished - product inventory is high and there is a concern about the decline in ethylene glycol price, for long - position spot exposure, shorting ethylene glycol futures (EG2601) with a 25% hedging ratio in the range of 3880 - 3980 can lock in profits and make up for production costs. Buying put options (EG2601P3750) and selling call options (EG2601C3900) with a 50% hedging ratio can prevent price drops and reduce capital costs [4]. - Procurement Management: When the procurement of regular inventory is low and procurement is to be made according to orders, for short - position spot exposure, buying ethylene glycol futures (EG2601) with a 50% hedging ratio in the range of 3700 - 3750 can lock in procurement costs. Selling put options (EG2601P3750) with a 75% hedging ratio can collect premiums to reduce procurement costs and lock in the purchase price of spot ethylene glycol if the price drops [4]. Polyester Daily Table 01 - Price: It shows the prices of various polyester - related products on 2025 - 11 - 27, 2025 - 11 - 26, and 2025 - 11 - 20, including Brent crude oil, naphtha, PX, PTA, ethylene glycol, polyester fibers, etc., as well as their daily and weekly changes [8]. - Spread: It includes the basis differences of TA, EG, PF, and the month - to - month spreads of PX, TA, EG, etc., and their daily and weekly changes [8][9]. - Processing Fee: It shows the processing fees and profits of various products such as gasoline reforming spread, aromatics reforming spread, naphtha cracking spread, etc., and their daily and weekly changes. It also includes the production and sales rates of polyester products [9]. Core Contradictions - Demand for polyester remains relatively high, with an expected load of over 91% in November and an adjusted average monthly load of slightly below 91% in December. Supply - side device accidents have led to a slowdown in inventory accumulation, but the weakening of coking coal trading in the cost side has reduced cost concerns, and the price has continued to decline. In the long - term, the oversupply situation persists, and the valuation pressure pattern cannot be reversed. The expectation of near - end inventory accumulation has been partially fulfilled, and the anti - risk ability has increased. The idea of shorting on rallies remains unchanged. The ethylene glycol price is expected to receive support around 3700 [5]. 利多解读 (Likely to be "Positive Interpretations") - Recently, there have been many unexpected shutdowns of ethylene glycol devices in the Chinese mainland, involving a total capacity of 1 million tons. Some overseas shutdown devices' restart expectations have also been delayed [6]. 利空解读 (Likely to be "Negative Interpretations") - A new 830,000 - ton/year MEG device in South China is planned to start trial production with ethylene feedstock in early November, and it is expected to bring a small additional supply increment in December [7].
