Opportunity signals

  • Price is above Fair Value, showing premium demand versus the model.

Risk signals

  • Trend Signal is inactive, so price action has not confirmed a constructive regime.
  • Price is below the Trend Line, which keeps downside pressure in focus.
  • Market Dynamics is negative, which weakens the current setup.
  • The share remains more than 20% below its 52-week high.

Watch next

  • Trend Line remains the key weekly regime level.
  • Market Dynamics is the pressure gauge to monitor for confirmation or fade.
  • A volume ratio above 1.5x would show stronger participation in the next move.
