This analysis is based on the phthalic anhydride price data released by official sources in China from September 1-2, 2026. The short-term trend is analyzed using the mean difference method. Currently, the phthalic anhydride price is at a high point within the last year's cycle. The short-term trend shows characteristics of fluctuation with a bearish bias. The momentum for a medium to short-term increase has weakened, and the upside potential is limited. Attention should be paid to the impact of plant operations and fluctuations in upstream raw materials.

II. Signal State Determination
The current average difference change combination is (unchanged, -, -), which falls within the oscillation range and is a signal of a weak rebound (bearish).
III. Trend Direction Conclusions
The short-term trend is biased towards a downtrend, due to the following reasons: The directions of the three moving average differences compared to the previous day are not entirely consistent, which does not meet the criteria for a clear uptrend or downtrend; specifically, the 10-day and 20-day moving average differences are both declining, indicating a reduction in the momentum for price increases in the short to medium term.
4. Spatial Reference
