October 21 report:
According to the SpotCom AI assistant, as of October 20, 2026, the average difference indicator shows that maleic anhydride is currently in a mild correction phase with a slightly bearish trend. The price is at a high level for the past year, with limited upside potential. The factory prices of maleic anhydride in major production areas such as Shandong and Jiangsu have declined for two consecutive days, and the overall market is consolidating weakly. Investors need to pay attention to the subsequent impact of changes in supply and demand on the price. The latest available data is up to October 20, 2026, and it is recommended to refer to real-time data.
I. Table of Finite Differences
| Difference Type | Value on 2026.10.20 | Value on 2026.10.19 | Direction of Change |
|---|---|---|---|
| 5-Day Difference D5 | -20.00 | 0.00 | - |
| 10-Day Difference D10 | 17.50 | 40.00 | - |
| 20-Day Difference D20 | 106.25 | 100.00 | + |
II. Signal State Determination
When the three consecutive first‑order differences change in the sequence (–, –, +), it constitutes a mild pullback (bearish, corrective) signal.
III. Conclusion on Trend Direction
The current maleic anhydride price trend in China is fluctuating (with a bearish bias).
Reason: The changes in the 5-day, 10-day, and 20-day periods do not consistently follow the same direction as the previous day, which does not meet the criteria for a clear upward or downward trend. This is characteristic of a fluctuating market, and currently, it shows a mild downward adjustment trend.
IV. Positional Spatial Reference
Maleic anhydride 60-day, 3-month, and 1-year cycle prices are all at high levels, corresponding to the 5th level (high) out of 5 levels, with limited room for further increases. Under the current bearish correction pattern, the risk of a price decline is relatively high.
