The short-term trend is clearly upward. Reason: The changes in the 5-day, 10-day, and 20-day averages are all positive and consistent with the previous day, meeting the criteria for a clear upward trend according to the average difference method. On a fundamental level, acetic acid companies generally have no inventory pressure, and the high prices of upstream raw materials like methanol provide strong cost support. Market participants have a strong sentiment to push up prices. Since mid-September, the factory prices of acetic acid in major production areas such as North China, South China, and Zhejiang have been continuously increasing, supported by both supply and demand factors.
4. Location and Spatial Reference
Acetic acid 60-day, 3-month, and 1-year cycle prices are all in the 5th tier (high), with limited room for short-term increases.
