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.
- Price is below Fair Value, so the market is still discounting the latest tape.
- 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.
