2. Signal Status Judgment
Currently, this constitutes a clear bearish signal.
3. Trend Direction Conclusion
The trend is clearly downward. Reason: The changes in the 5-day, 10-day, and 20-day moving averages compared to the previous day are all negative, meeting the criteria for a clear downward trend.
4. Spatial Reference
PC prices are at the median level over a 60-day cycle, in the upper‑mid range over a three‑month cycle, and at the median level over a one‑year cycle. The upper‑mid positioning suggests limited room for a substantial further rally, while the median level implies some volatility in both directions. Amid the current downtrend, it is worth monitoring the strength of support in the lower‑to‑mid price range.
