What does it mean?
- 8-week price move: 1.73%. Weekly return volatility: 1.35%. Close is 0.63% below the prior-window 8-week high. and 3.63% above the prior-window 8-week low. Volume trend: rising. Latest week’s volume is 0.22σ from its 8-week average. Price/volume correlation (returns vs volume): 0.11. Price/volume correlation (returns vs volume change): 0.24. 26-week move: -1.75%. 52-week move: -24.32%. Price sits 0.13% below its medium-term baseline, and the distance is widening. Moving-average stack is weak (short below intermediate below long).
- How to read this — Price slope is downward, indicating persistent supply pressure. Low weekly volatility favours steadier follow-through. Volume trend diverges from price — watch for fatigue or rotation. Weak MA stack argues for caution; rallies can fail near the 8–13 week region.
- Down-slope argues for patience; rallies can fade sooner unless participation improves. Because liquidity isn’t confirming, prefer evidence of fresh demand before chasing moves.
