2. Signal Status Judgment
Stagflation Alert (Bearish)
3. Trend Direction Conclusion
Volatility, reason: The direction of change in the three mean differences is not entirely consistent with the previous day; the combination of signs is (+, -, +), which meets the volatility criteria for stagflation warning (bearish).
4. Positional Spatial Reference
The PTA 1-year cycle price is at a medium-to-high level, with limited room for further increases; the 60-day cycle is at a mid-level, and the 3-month cycle is at a medium-to-low level. Given the constrained upward potential above the current price level and the combination with bearish oscillation signals, attention should be paid to the risk of a price pullback.
