●Call wall at $370 (4k contracts), 4% above spot — the upside strike the crowd is already parked on; often acts as near-term resistance.
●Put wall at $340 (2k contracts), 5% below spot — the hedge floor; often acts as support.
●Deep-OTM put open interest is 2.9× deep-OTM call OI — an institutional hedging ladder sits under this stock.
●30-day ATM implied volatility is 21% — calm pricing; option premium is cheap.
