Weekly setup
Constructive, but selective
The weekly trend is active. Price is 5.0% above the Trend Line and sits at 63.2% of its 52-week range. The latest completed week returned 1.9%, after a 0.4% four-week move. Near-term considerations: volume confirmation is below normal.

vs 13-week average
- Price is below Fair Value, so the market is still discounting the latest tape.
- Next-week expectancy is negative at 31.21% based on similar historical setup states.
- Activity pressure is weak, so confirmation is not yet broad enough.
- Trend Line remains the key weekly regime level.
- Activity pressure is the gauge to monitor for confirmation or fade.
- A volume ratio above 1.5x would show stronger participation in the next move.

Is real participation confirming the move?
Latest weekly volume is 0.6x the 13-week average. Participation is below its recent norm, so price strength is not receiving full volume confirmation.
