3. Trend Direction Conclusion
The current styrene price trend is fluctuating. Reason: The direction of change in the three averages compared to the previous day is not entirely consistent, which does not meet the criteria for a clear upward or downward trend, indicating a fluctuating range. Additionally, with the signal of resistance to decline, the probability of a stronger short-term fluctuation is higher. As a reference, recent continuous increases in styrene ex-factory quotes by Chinese petrochemical manufacturers have provided strong support for the spot price. On September 11, the external Asian styrene price slightly declined, but it had limited impact on the market sentiment in China.
4. Positional Spatial Reference
- Prices for both the 60-day and 3-month cycles are at the 5th tier (high level), limiting short-term upside potential.
- The 1-year cycle price is in the 4th tier (moderately high), and there is still some room for flexibility in the medium to long term.
