2. Signal Status Judgment
Currently, this is a weak rebound (bearish) signal.
3. Trend Direction Conclusion
The trend is range-bound (with a bearish bias). Reason: The 5-day, 10-day, and 20-day moving averages all exhibit slightly divergent directional changes compared to the previous day, with a positive–negative–negative combination. This pattern aligns with the characteristics of a bearish‑biased rebound within a ranging market, while medium- to long-term upward momentum has begun to weaken.
4. Positional Space Reference
- Near‑1‑year cycle: PC prices are at the third tier (mid‑range), with relatively balanced upside and downside potential.
- Over the past three-month cycle: PC prices are in the fourth tier (mid-to-high range), facing significant upward pressure;
- Near‑60‑day cycle: PC prices are at the second tier (mid‑to‑low range), leaving room for a short‑term corrective rally, but constrained by the medium‑term trend, limiting the sustainability of any rebound.
