September 11 news
As of September 10, 2026, the short-term trend of PVC spot prices in China is a downward correction within a volatile pattern. In the short term (60 days / 3 months), prices are in a high range, with insufficient upward momentum and pressure for a pullback. Over the long term (1 year), prices are in a medium to low range, with limited room for further significant declines. The high price of upstream raw material calcium carbide provides some support to the cost side of PVC, while weak downstream demand is the main driver of the current price correction. Going forward, it will be important to closely monitor changes in supply and demand dynamics and the trend in upstream raw material prices.
Data Description
The latest available data is up to September 10, 2026. It is recommended to refer to real-time data.
1. Average Difference Change Table
| Average Difference Type | Value on 2026.09.10 | Value on 2026.09.09 | Direction of Change |
|---|---|---|---|
| 5-day Average Difference (D5) | 17.6 | 57.6 | - |
| 10-day Average Difference (D10) | 74.2 | 86.2 | - |
| 20-day Average Difference (D20) | 196.35 | 190.25 | + |
2. Signal Status Determination
The current mean difference change combination is (－, －, ＋), which matches the characteristics of a deep pullback (biased towards short, pullback nature) signal in the mean difference method.
3. Trend Direction Conclusion
The short-term trend is judged to be volatile (with a bearish pullback).
Reason: The three average differences did not all move in the same direction as the previous day, failing to meet the criteria for a clear upward or downward trend. Therefore, the overall market is characterized by a volatile trend. Moreover, given the currently weak purchasing enthusiasm at the spot market’s end-user level and the slight easing of dealer quotes, this further confirms the bearish corrective nature of the market.

6. Upstream and Downstream Industry Chain Reference
Upstream core raw material: The current 60-day/3-month price of calcium carbide is at a high level, providing some support to the cost side of PVC and can mitigate the extent of PVC price adjustments.
Downstream core demand sectors: Recent purchasing demand in terminal areas such as PVC profiles, PVC pipes, and PVC films has been weak, and insufficient transactions are the main drivers of the current price adjustments.
