August 28 news
As of August 27, 2026, the Chinese PVC spot market has generally shown a weak and consolidating trend, with futures prices fluctuating within a narrow range. In mainstream consumer markets such as Zibo and Linyi in Shandong Province, dealers’ quoted prices have mostly remained unchanged. For PVC grade 5 produced via the calcium carbide method, the mainstream pickup/quote range has been concentrated between 4,390 and 4,450 CNY per ton. Upstream production facilities are operating at stable rates, and trading activity within the market remains subdued; overall transaction performance, however, remains reasonably good. The following is a price trend analysis based on the mean difference method:
1. Mean Difference Change Table
| Mean Difference Indicator | Value on 2026.8.27 | Value on 2026.8.26 | Direction of Change |
|---|---|---|---|
| 5-day Mean Difference (D5) | -27.6 | -44.4 | + |
| 10-day Mean Difference (D10) | -37.2 | -33.1 | - |
| 20-day Mean Difference (D20) | 3.35 | 9.70 | - |
2. Signal Status Judgment
The current deviation change combination is (+, -, -), which is a weak rebound (bearish) signal.
3. Trend Direction Conclusion
The current PVC price trend is fluctuating (with a bearish bias), due to the fact that the changes in the three averages compared to the previous day are not entirely consistent, which does not meet the criteria for a clear upward or downward trend. Therefore, it is determined to be a fluctuating trend, indicating a weak rebound with a bearish signal, and the short-term upward momentum is relatively weak.
4. Position Space Reference
PVC 60-day and 3-month cycle prices are both in the 2nd tier (lower-middle), while the 1-year cycle price is in the 1st tier (low). The overall downward space is limited, but due to the recent weak performance of the spot market, the short-term upward space is also narrow.
