On August 17, the price of acetone fluctuated within a range, with the mean difference indicator issuing a warning signal for a slowdown in growth. The price is at a mid-level over a 1-year cycle and at a high level over a 60-day cycle, limiting the short-term upward potential. Attention should be paid to the price correlation effects of upstream propylene, pure benzene, and downstream bisphenol A.
I. Table of Mean Difference Changes
| Average Difference Type | Today's Value (2026-08-17) | Yesterday's Value (2026-08-16) | Direction of Change |
|---|---|---|---|
| 5-day Average Difference (D5) | 23.75 | -30.00 | + |
| 10-day Average Difference (D10) | 23.75 | 41.25 | - |
| 20-day Average Difference (D20) | 104.37 | 100.00 | + |
II. Signal State Determination
The current combination of mean difference change symbols is (+, -, +), which is a stagflation warning (bearish) signal in China.
III. Conclusion on Trend Direction
The price trend is oscillating. Reason: The directions of the three average differences compared to the previous day are not entirely consistent. The 5-day average difference has turned from negative to positive, the 10-day average difference has decreased, and the 20-day average difference has slightly increased. This aligns with the characteristics of a stagnation warning within the range of oscillation, indicating that the short-term upward momentum has weakened.
IV. Positional Spatial Reference
1 year cycle price position: median, with relatively balanced room for increase and decrease;
Price positioning for the 3-month cycle: Mid-to-high range, with narrowing upside potential;
60-day price cycle position: At a high level, with limited short-term upside potential; be cautious of downside risks.
