The current combination of changes in the equal‑difference series is (+, +, −), which meets the criteria for a strong rebound (bullish, rebound‑type) signal.
3. Conclusion on Trend Directions
The current phthalic anhydride price trend is fluctuating (with a bullish bias). The reason is that the 5-day and 10-day moving averages are higher than the previous day, while the 20-day moving average is lower than the previous day. Since the directions of change for these three indicators are not completely consistent, it is determined to be a fluctuating trend. Coupled with a strong rebound and a bullish signal, the short-term trend is relatively strong.

6. Fundamental Reference
Supply side: Chinese phthalic anhydride manufacturers have increased their operating load, with overall inventory at a low level.

Cost side: Crude oil prices are fluctuating upwards, while ortho-xylene and industrial naphthalene prices are stable, providing strong cost support. Demand side: The operating load of downstream plasticizer enterprises has increased, and there is still support from rigid demand procurement.
