What the positioning says

●Bullish positioning: only 0.65 puts per call outstanding.
●Call wall at $175 (16k contracts), 8% above spot — the upside strike the crowd is already parked on; often acts as near-term resistance.
●Put wall at $160 (6k contracts), 1% below spot — the hedge floor; often acts as support.

IV term structure

At-the-money implied volatility per expiry.

Volatility smile

IV by strike — expiry 2026-10-30. 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.
