Report Industry Investment Rating - Not provided in the given content Core Viewpoints - The current maintenance of ethylene glycol plants has led to an expansion of supply reduction, and the supply - demand structure is relatively good. Polyester production remains at a high level. The result of the Sino - US trade negotiation exceeded market expectations, the terminal export expectation was repaired, orders were advanced, and the stocking demand may increase significantly. Under strong expectations, ethylene glycol should be treated with cautious optimism, and the actual arrival rhythm of ports should be continuously monitored [2][3] Summary by Relevant Catalogs 1. Daily Market Summary - **Price**: The price of the main ethylene glycol futures contract fell slightly by 0.39% to 4,398 yuan/ton, while the spot price in the East China market rose by 35 yuan to 4,575 yuan/ton, and the basis widened to 172 yuan/ton [2] - **Supply**: Multiple ethylene glycol production facilities are under maintenance. As of May 15, the overall ethylene glycol operating load in mainland China was 60.51% (down 8.48% from the previous period). From May 12 - 18, the planned arrival volume at major ports was about 5.5 tons [2] - **Demand**: The polyester factory load was 94.2%. The domestic weaving comprehensive operating rate was around 63.80%, up 63.80% from last week. The comprehensive operating rate in the Jiangsu and Zhejiang regions was 60.68%, up 0.62% from last week [3] - **Inventory**: As of May 18, the inventory at major ports in East China was about 74.3 tons, a decrease of 0.8 tons from the previous period [3] 2. Industrial Chain Price Monitoring - **Futures and Spot**: The main ethylene glycol futures contract price decreased by 0.39%, the trading volume decreased by 16.16%, and the open interest decreased by 1.49%. The spot price in the East China market increased by 0.77%, and the basis increased by 10.97% [5] - **Profit**: The ethylene - based production profit decreased by 0.92%, while the coal - based production profit remained unchanged [5] - **Operating Rate**: The overall ethylene glycol operating rate, coal - based and oil - based operating rates, polyester factory load, and Jiangsu - Zhejiang loom load remained unchanged [5] - **Inventory and Arrival**: The inventory at major ports in East China decreased by 4.08%, and the arrival volume increased by 26.32% [5] 3. Industrial Chain Data Charts - The report includes charts on the closing price and basis of the main ethylene glycol contract, ethylene glycol production profit, and the operating rate of downstream polyester plants [6][8][10] 4. Appendix: Big Model Inference Process - The ethylene glycol futures price decreased, the spot price increased, and the basis widened. The production profit was in a loss state, which may affect the future operating rate. The overall supply was stable, and the demand showed limited growth. The port inventory decreased, but the increase in arrival volume may bring subsequent pressure. Overall, ethylene glycol may maintain a volatile trend [13][15][16]

Core Viewpoint - Domestic ethylene glycol prices have experienced fluctuations in 2023, with a notable drop in early April, but a potential recovery is anticipated following positive developments in US-China trade talks [1][7]. Supply and Demand Dynamics - The apparent consumption and production of domestic ethylene glycol have been increasing, with a projected demand growth of 590,000 tons from 2020 to 2024 due to the expansion of polyester production capacity [2]. - Domestic ethylene glycol production capacity is expected to rise from 15.54 million tons in 2020 to 27.92 million tons in 2024, leading to an oversupply situation and significant profit declines for companies [2]. - The overall operating rate for ethylene glycol production remains below 70%, with coal-based production facilities operating at around 50% due to ongoing losses [3]. Production Routes and Profitability - The production capacity of oil-based ethylene glycol accounts for two-thirds of the total capacity, and recent declines in international oil prices have improved profit margins for these facilities [4]. - Coal-based ethylene glycol has faced negative profit margins for the past four years, but recent decreases in coal prices have reduced losses and improved operating rates [5]. - Ethane-based production has advantages due to lower raw material costs, but recent tariffs have impacted sourcing from the US, prompting companies to seek alternatives [5]. Import Trends - The reliance on imports for ethylene glycol has decreased, with the import dependency rate falling to 25%-30% in recent years [6]. - In Q1 2023, ethylene glycol imports totaled 1.9626 million tons, a 42.73% increase year-on-year, with major suppliers being Saudi Arabia, the US, and Canada [6]. Market Outlook - Recent financial policies and improved US-China relations are expected to stabilize and potentially increase ethylene glycol prices [7]. - Despite supply-side pressures from domestic facility restarts, upcoming maintenance schedules and reduced port arrivals are likely to support price recovery [8]. - The textile industry, which accounts for about 50% of global production, is expected to drive demand for ethylene glycol, especially with easing trade tensions [8].

Core Viewpoint - Zhongyida's stock price has increased by 298.76% since March 10, 2025, despite the company reporting a net loss of 14.08 million yuan for the fiscal year 2024 [1]. Financial Performance - The company reported a net profit of 13.76 million yuan in the first quarter of 2025 [1]. - As of the end of the first quarter of 2025, the company's goodwill was valued at 160 million yuan, while its net asset value was 81.01 million yuan, indicating that the goodwill exceeds the net asset value [2]. - The cumulative undistributed profit balance as of December 31, 2024, was -2.098 billion yuan, which means profits will first be used to cover previous losses before any cash dividends can be distributed [2].
