deep-OTM puts vs calls

What the positioning says

●Defensive positioning: 2.24 puts outstanding per call — holders are hedging rather than selling.
●Call wall at $800 (291k contracts), 4% above spot — the upside strike the crowd is already parked on; often acts as near-term resistance.
●Put wall at $525 (539k contracts), 32% below spot — the hedge floor; often acts as support.
●Deep-OTM put open interest is 5.7× deep-OTM call OI — an institutional hedging ladder sits under this stock.
●30-day ATM implied volatility is 13% — calm pricing; option premium is cheap.
