August 18th News
On August 17, 2026, the price of propylene oxide in China showed a clear upward trend, with the 5-day, 10-day, and 20-day moving averages all rising in sync compared to the previous day, conforming to the rule for a clear upward trend as determined by the moving average method. From a cyclical perspective, the annual price of the product is at a mid-level, with relatively balanced potential for increases and decreases. However, in the short term, both the 60-day and 3-month cycles are at high levels, indicating that the momentum and space for further short-term increases are relatively limited. Overall, the situation presents a favorable long-term trend but faces pressure in the short term for continued increases.
I. Data on changes in mean differences
This statistics cover three core mean difference indicators of 5-day, 10-day, and 20-day, comparing the values and change directions between August 16, 2026 (yesterday) and August 17, 2026 (today). The specific data are as follows:
| Average Difference Type | Today's Value (2026-08-17) | Yesterday's Value (2026-08-16) | Direction of Change |
|---|---|---|---|
| 5-day Average Difference (D5) | 266.67 | 53.33 | + |
| 10-day Average Difference (D10) | -13.34 | -156.66 | + |
| 20-day Average Difference (D20) | 45.00 | 31.66 | + |
II. Signal State Determination
According to the core mean difference index data monitoring, the 5-day, 10-day, and 20-day mean difference indices have all changed in a completely unified direction compared to the previous day, all showing a positive recovery trend. The resonance effect of the indicators is significant, forming an effective signal for a clear upward trend.
Three, Conclusions on Trend Directions
The current propylene oxide price shows a clear upward trend overall. The core basis for this is the simultaneous positive changes in the three key average difference indicators: short-term, medium-term, and medium-long term. This perfectly aligns with the rule in the average difference method that "a multi-period average difference moving in the same upward direction indicates a clear upward trend." The overall bullish trend signal in the Chinese market has been established.
IV. Reference for Price Levels and Upside/Downside Potential
From the perspective of price quantiles at different time periods, the price trend of propylene oxide shows a divergent characteristic: in the long-term cycle of 1 year, the price is at the 3rd mid-level, with a relatively balanced overall fluctuation space and no obvious unilateral pressure for increase or decrease; in the short-term cycles of 60 days and 3 months, the price is in the 5th high-level range, with increased resistance to short-term price increases, relatively limited upward space, and the possibility of high-level fluctuations and adjustments.
