III. Conclusions on Trend Directions
The current PC price trend in China is fluctuating. Reason: The direction of change in the three averages compared to the previous day is not entirely consistent, and does not meet the criteria for a clear upward or downward trend. Fundamental supplement: Currently, the plant load of PC production enterprises in China is generally stable, with normal supply of goods and acceptable sales. The relatively strong prices of upstream bisphenol A and dimethyl carbonate provide some support to the cost side of PC.
IV. Spatial Reference
The 60-day PC price cycle is in the 5th tier (high level), the 3-month cycle is in the 4th tier (mid-to-high level), and the 1-year cycle is in the 3rd tier (mid-level):
- The short-term price is at a relatively high level, with limited room for increase;
- It has remained in the middle range in the medium to long term, but still has some room for fluctuation.
