Recently, the domestic PVC spot market has shown a pattern of range-bound fluctuation, with slight adjustments in quotations in some regions. Upstream facilities have maintained stable operations, while downstream transaction activity has been moderate. Based on the analysis of the average difference indicators and price levels, the current price is in a phase of oscillating correction. The low position attribute over a 1-year cycle may limit the downward space to some extent. Subsequent attention should be paid to the futures trend and changes in supply and demand.
I. Table of Mean Difference Changes
| Average Difference Type | Today's Value (2026-08-13) | Yesterday's Value (2026-08-12) | Direction of Change |
|---|---|---|---|
| 5-day Average Difference (D5) | -5.1 | 0.9 | - |
| 10-day Average Difference (D10) | 8.3 | 16.1 | - |
| 20-day Average Difference (D20) | 0.85 | -6.95 | + |
II. Signal State Determination
The current average difference change symbol combination is (-, -, +), which belongs to a deep correction (biased bearish, corrective nature) signal.
III. Trend Direction Conclusions
The price trend is oscillating. Reason: The directions of the three mean differences are not entirely consistent; the 5-day and 10-day mean differences have decreased compared to yesterday, while the 20-day mean difference has increased, which aligns with the characteristics of a deep pullback signal within an oscillating range.
IV. Spatial Reference
60-day cycle price position: Median
Price position for the 3-month cycle: Mid-to-low level
1 year cycle price position: low, with limited downside space
From a multi-cycle perspective, the 1-year cycle is in a low position, indicating that the room for further price declines is relatively limited; the 60-day cycle is in a middle position, suggesting that there may still be short-term fluctuations and adjustments.
