What the positioning says

●Defensive positioning: 1.12 puts outstanding per call — holders are hedging rather than selling.
●Call wall at $600 (509 contracts), 12% above spot — the upside strike the crowd is already parked on; often acts as near-term resistance.
●Put wall at $370 (467 contracts), 31% below spot — the hedge floor; often acts as support.

Volatility smile

IV by strike — expiry 2026-10-16. A steep left side = expensive downside protection.

30-day implied volatility history

Daily ATM IV (~30 DTE bucket) collected since March 2026. Rising IV into an event = the market bracing; collapsing IV after = the crush.
