What the positioning says

●Bullish positioning: only 0.52 puts per call outstanding.
●Call wall at $45 (1k contracts), 14% above spot — the upside strike the crowd is already parked on; often acts as near-term resistance.
●Put wall at $35 (164 contracts), 11% below spot — the hedge floor; often acts as support.
●Deep-OTM call OI is 10.0× deep-OTM put OI — speculative upside positioning dominates the tails.
●30-day ATM implied volatility is 22% — calm pricing; option premium is cheap.

Volatility smile

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

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