IV. Conclusion on Trend Direction
The current trend in maleic anhydride prices is fluctuating. Reason: The changes in the 5-day, 10-day, and 20-day moving averages compared to the previous day are not entirely consistent, failing to meet the criteria for a clear upward or downward trend. In the short term, it is in a fluctuation range, with a more prominent overall downward adjustment attribute.
V. Positional Space Reference
Maleic anhydride 60-day, 3-month, and 1-year cycle prices are all in the 5th tier out of 5 tiers (high range), meaning the current price is in the highest 20% range within the cycle, with limited room for further increases, and there is a need to be cautious about the risk of a pullback from these high levels.
