September 4, 2026, based on the latest spot data, calculations show that despite the general increase in phthalic anhydride prices from Chinese manufacturers over the past 3 days, a stagnation warning (bearish) signal has appeared. The current price is at a high level within the last year's cycle, and there is insufficient momentum for further short-term increases. Caution is needed against the risk of a pullback from the high levels.
Data Description
The latest available phthalic anhydride data for China is up to September 3, 2026. It is recommended to refer to real-time data.
II. Table of Mean Difference Changes
| Average Difference Type | Value as of September 3, 2026 | Value as of September 2, 2026 | Direction of Change |
|---|---|---|---|
| 5-day Average Difference (D5) | 66.66 | 0 | + |
| 10-day Average Difference (D10) | 8.34 | 11.67 | - |
| 20-day Average Difference (D20) | 92.5 | 89.16 | + |
3. Signal Status Judgment
The current three mean difference change direction combinations are (+, -, +), which align with the Stagnation Warning (Bearish) signal in the oscillation category.
4. Trend Direction Conclusion
The current phthalic anhydride price trend is judged to be volatile (with a bearish bias). The reason is that the changes in the 5-day, 10-day, and 20-day moving average differences from the previous day are not completely consistent, which does not meet the criteria for a clear upward or downward trend. This is considered a volatile market, and the signals indicate a stall with a bearish bias.
From a fundamental perspective, in the past three days, phthalic anhydride manufacturers in China have generally raised their prices: on September 3, Zhenjiang Liancheng and Tongling Chemistry increased their phthalic anhydride quotes by 100 CNY/ton to 9500 CNY/ton, Shijiazhuang Bailong increased its quote by 100 CNY/ton to 9300 CNY/ton, and Changzhou Xinyang increased its quote by 50 CNY/ton to 9500 CNY/ton. Most manufacturers have low inventory levels and tight supply, but signals indicate that the momentum for price increases is insufficient.
V. Positional Spatial Reference
Phthalic anhydride prices over the past 60 days, 3 months, and 1 year in China have all been in the 5th tier (high position), with limited room for further increases and a possibility of a decline from the high levels.
