September 18th News
According to the SpotCom AI assistant, on September 17, 2026, the Chinese maleic anhydride market remained stable overall, with no significant adjustments in the ex-factory quotes from major factories in Jiangsu and Shandong. Based on the average difference method, the current combination of changes in the average difference for maleic anhydride is (+, -, +), which is a retracement (bullish) signal, indicating a short-term price trend that is oscillating but slightly bullish. The 60-day, 3-month, and 1-year cycle prices for maleic anhydride are currently in a high range, with limited upside potential. Subsequently, it is necessary to closely monitor the changes in upstream raw material prices and the release of downstream demand.

II. Table of Mean Difference Changes
| Average Difference Type | Value as of Sep 17, 2026 (CNY/ton) | Value as of Sep 16, 2026 (CNY/ton) | Direction of Change |
|---|---|---|---|
| 5-day Average Difference (D5) | 317.50 | 235.00 | + |
| 10-day Average Difference (D10) | 411.25 | 426.25 | - |

Three, Signal Status Judgment
The current three difference change combinations are (+, -, +), which belong to a retracement (bullish) signal.
IV. Conclusion on Trend Direction
The short-term price trend is characterized by oscillations with a slight bullish bias. Reason: The directions of change in the three moving averages are not entirely consistent with the previous day, failing to meet the criteria for a clear upward or downward trend; therefore, the overall trend is one of oscillation. The signal type is a pullback, which carries a slightly bullish characteristic.
Five, Spatial Reference
Maleic anhydride 60-day, 3-month, and 1-year cycle prices are all in the 5th tier (high) of a 5-tier division, with limited room for further increases. Without sustained positive drivers, there is a possibility of a price correction from these high levels.
