deep-OTM puts vs calls

What the positioning says

●Defensive positioning: 1.37 puts outstanding per call — holders are hedging rather than selling.
●Call wall at $270 (851 contracts), 16% above spot — the upside strike the crowd is already parked on; often acts as near-term resistance.
●Put wall at $220 (3k contracts), 6% below spot — the hedge floor; often acts as support.
●Deep-OTM call OI is 7.4× deep-OTM put OI — speculative upside positioning dominates the tails.
●30-day ATM implied volatility is 24% — calm pricing; option premium is cheap.

IV term structure

At-the-money implied volatility per expiry.

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.
