What the positioning says

●Call wall at $240 (3k contracts), 5% above spot — the upside strike the crowd is already parked on; often acts as near-term resistance.
●Put wall at $200 (2k contracts), 12% below spot — the hedge floor; often acts as support.
●Deep-OTM put open interest is 3.7× deep-OTM call OI — an institutional hedging ladder sits under this stock.

Volatility smile

IV by strike — expiry 2026-11-20. 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.
