What the positioning says

●Defensive positioning: 2.39 puts outstanding per call — holders are hedging rather than selling.
●Call wall at $45 (14 contracts), 5% above spot — the upside strike the crowd is already parked on; often acts as near-term resistance.
●Put wall at $40 (67 contracts), 7% below spot — the hedge floor; often acts as support.
●30-day ATM implied volatility is 62% — the market prices very large moves; option premium is expensive.
