What the positioning says

●Bullish positioning: only 0.23 puts per call outstanding.
●Call wall at $140 (4k contracts), 10% above spot — the upside strike the crowd is already parked on; often acts as near-term resistance.
●Put wall at $110 (289 contracts), 14% below spot — the hedge floor; often acts as support.
●Deep-OTM call OI is 5.1× deep-OTM put OI — speculative upside positioning dominates the tails.

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