September 22nd, according to reports
According to the SpotCom AI assistant, this report is based on publicly available mean difference indicators and spot transaction price data to analyze the short-term price trend of maleic anhydride. The current combination of mean difference changes shows a moderate correction (bearish) signal. The 1-year cycle price is in a high range, with limited upside potential. Recently, the factory prices of maleic anhydride in the two major production areas of Jiangsu and Shandong, China, have been continuously declining, and the overall market is showing a weak and volatile operating trend. The latest available data is up to September 21, 2026, and it is recommended to refer to real-time data.
I. Table of Finite Differences
| Difference Type | Value as of 2026.09.21 | Value as of 2026.09.20 | Direction of Change |
|---|---|---|---|
| 5-Day Difference (D5) | -115.00 | -65.00 | - |
| 10-Day Difference (D10) | 175.00 | 266.25 | - |
| 20-Day Difference (D20) | 586.87 | 565.62 | + |
II. Signal State Determination
When the sign combination of the three successive divided differences is (–, –, +), it corresponds to a mild pullback (bearish, corrective in nature) signal under the divided difference rule.
III. Conclusion on Trend Direction
The current trend in maleic anhydride prices in China is fluctuating.
Reason for the judgment: The 5-day, 10-day, and 20-day moving averages all exhibit slightly divergent directional changes compared to the previous day, meeting the criteria for an oscillating trend. Coupled with a mild pullback that leans bearish, the short-term price action is expected to remain weakly volatile.
IV. Positional Spatial Reference
Maleic anhydride is in the 5th tier (high position) of a 1-year price cycle, with limited room for further increase. During the correction phase, it is crucial to closely monitor changes in supply and demand at both upstream and downstream ends for their support on the price.
