August 21st News
On August 20, the Chinese PVC spot market saw a slight decline, with dealers in Zibo and Linyi regions reporting a decrease of 20-30 yuan from the previous day. The futures market's midday drop led to a follow-up decline in the spot market. The average difference indicator shows that the current market is in a strong consolidation (bullish) phase, with prices at a low point over a one-year period, indicating limited downward space. In the short term, attention should be paid to the trend of the futures market and changes in the spot trading atmosphere.

| 20-day Average Difference (D20) | 21.05 | 20.85 | + |
II. Signal Status Determination
The current deviation change direction combination is (-, +, +), which conforms to the characteristics of a strong consolidation (biased towards bullish) signal.
Three, Conclusions on Trend Directions in China
The price trend is oscillating. Reason: The directions of the three differences in moving averages are not entirely consistent (the 5-day difference has decreased compared to yesterday, while the 10-day and 20-day differences have increased compared to yesterday), which does not meet the criteria for a clear trend. Therefore, it is judged to be an oscillating trend, with an overall characteristic of strong consolidation tending towards bullishness.
IV. Positional Spatial Reference
1-year price positioning: at a low level, with limited room for further decline;
Price position over a 3-month cycle: Median, with relatively balanced upside and downside potential;
60-day cycle price position: at a medium-high level, the short-term upward space may be somewhat limited.
Overall, the risk of a decline is relatively low in the long term, but in the short term, attention should be paid to the pressure performance in the mid-to-high range.
