What the positioning says

●Defensive positioning: 1.20 puts outstanding per call — holders are hedging rather than selling.
●Call wall at $65 (2k contracts), 5% above spot — the upside strike the crowd is already parked on; often acts as near-term resistance.
●Put wall at $60 (1k contracts), 3% below spot — the hedge floor; often acts as support.

Volatility smile
