2. Signal Status Determination
Stagflation warning (Bearish)
3. Trend Direction Conclusion
Volatility. Reason: The directions of the three mean differences are not entirely consistent, with the sign combination being (+, -, +), which aligns with the volatility signal for a stagnation warning in the mean difference method. There is no clear short-term direction for a unilateral rise or fall, and the overall trend is biased towards volatility.
4. Positional Space Reference
Styrene prices are at the mid-level for a 1-year cycle, at a high-mid level for a 3-month cycle, and at a high level for a 60-day cycle. A high level indicates limited short-term upside potential and requires caution against the risk of a pullback.
