What the positioning says

●Defensive positioning: 1.84 puts outstanding per call — holders are hedging rather than selling.
●Call wall at $120 (6k contracts), 11% above spot — the upside strike the crowd is already parked on; often acts as near-term resistance.
●Put wall at $80 (10k contracts), 26% below spot — the hedge floor; often acts as support.
●Deep-OTM put open interest is 3.1× deep-OTM call OI — an institutional hedging ladder sits under this stock.
