  • Activity pressure is positive on the latest completed week.
  • Volume is elevated versus the 13-week average, confirming attention.
What could go wrong
  • The trend backdrop is inactive, so price action has not confirmed a constructive regime.
  • Price is below Fair Value, so the market is still discounting the latest tape.
  • Activity pressure is weak, so confirmation is not yet broad enough.
  • The share remains more than 20% below its 52-week high.
What to watch next
  • Trend Line remains the key weekly regime level.
  • Activity pressure is the gauge to monitor for confirmation or fade.
