On August 20, 2026, DOP prices continued their upward trend, and the mean difference indicator showed a clear bullish signal. Several manufacturers have raised their quotes for consecutive days. From a price perspective, DOP is at the high end of its one-year cycle as well as the high levels of both the 60-day and three-month cycles; therefore, in the short term, attention should be paid to the resistance at these higher levels as the room for further price increases narrows.
DOP Spot Price Market Daily Report (2026-08-20)
I. Table of Mean Difference Changes
| Average Difference Type | Today's Value (2026-08-20) | Yesterday's Value (2026-08-19) | Direction of Change |
|---|---|---|---|
| 5-day Average Difference (D5) | 130 | 95 | + |
| 10-day Average Difference (D10) | 100 | 80.84 | + |
| 20-day Average Difference (D20) | 97.5 | 66.66 | + |
II. Signal State Determination
The current three differences are all positive, indicating a clear upward trend.
III. Trend Direction Conclusions
The price trend is clearly upward. Reason: The 5-day, 10-day, and 20-day average differences compared to yesterday are all positively growing, and the direction of all three is completely consistent, meeting the criteria for a clear upward trend according to the average difference method; at the same time, in the spot market, multiple mainstream production companies such as Zhejiang Hongbo, Shandong Shengfeng, and Dongying Yimeide have raised their DOP quotes for three consecutive days, with actual transaction prices also rising, and the market transaction atmosphere supports the upward trend in prices.
IV. Positional Spatial Reference
The DOP price has been at a medium-to-high level over the past one-year period and remains at a high level over the 60-day and three-month periods. This high-price range suggests limited short-term upside potential. Going forward, it will be crucial to monitor the trends of upstream raw materials such as n-octanol and phthalic anhydride, as well as changes in downstream demand for PVC plasticizers, and to remain vigilant about the risk of a price correction from the current high levels.
