What the positioning says

●Bullish positioning: only 0.68 puts per call outstanding.
●Call wall at $1,600 (2k contracts), 25% above spot — the upside strike the crowd is already parked on; often acts as near-term resistance.

●30-day ATM implied volatility is 23% — calm pricing; option premium is cheap.

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.
