This daily report, based on the analysis of average difference, integrates the latest spot price, moving average data, and the supply and demand situation of the industrial chain as of October 19, 2026. The current DOP average difference combination is (+, -, -), indicating a weak rebound with a bearish signal. The price is at a high level within the recent 1-year cycle, showing an overall oscillating pattern in the short term, with limited upward potential. It is recommended to closely monitor the cost trends of upstream materials, such as 2-ethylhexanol and phthalic anhydride, and the demand for downstream PVC plasticizers in China.
The latest available DOP data is up to October 19, 2026. It is recommended to refer to real-time data.
I. Table of Finite Differences
| Mean Difference Indicator | Value on October 19, 2026 | Value on October 18, 2026 | Direction of Change |
|---|---|---|---|
| 5-Day Mean Difference (D5) | 13.33 | 0 | + |
| 10-Day Mean Difference (D10) | -5 | 5.83 | - |
| 20-Day Mean Difference (D20) | 155.83 | 159.59 | - |
II. Signal State Determination
The current three deviation change direction combinations are (+, -, -), which align with the characteristics of a weak rebound (bearish) signal in China.
III. Conclusion on Trend Direction
The current DOP price trend is oscillating. Reason: The direction of change in the three averages compared to the previous day is not entirely consistent, failing to meet the criteria for a clear upward or downward trend, and thus it is in a weak rebound with a bearish bias within an oscillating range. From the perspective of the spot market, on October 19, Shandong Shengfeng Chemical's DOP quotation increased by 100 CNY/ton compared to the previous quotation, and the spot transaction price slightly rose, but there is no short-term continuous one-sided upward momentum.
IV. Positional Space Reference
The current DOP price is in the 5th tier (high) for the 60-day, 3-month, and 1-year periods. The upside is limited, and if there is no significant increase in demand, the momentum for further price increases will be insufficient.

VI. Industry Chain Reference
The upstream raw materials for DOP are primarily n-octanol, phthalic anhydride, and isooctanol; the latter is currently at a cyclical peak, providing strong cost support for DOP. Downstream, DOP is mainly used as a plasticizer for PVC; however, downstream purchasing sentiment remains cautious, resulting in only moderate demand-side support.
Risk Warning
The above analysis is for reference only and does not constitute trading advice.
