What the positioning says

●Bullish positioning: only 0.63 puts per call outstanding.
●Call wall at $115 (16k contracts), 2% above spot — the upside strike the crowd is already parked on; often acts as near-term resistance.
●Put wall at $80 (10k contracts), 29% below spot — the hedge floor; often acts as support.
●Deep-OTM put open interest is 2.7× deep-OTM call OI — an institutional hedging ladder sits under this stock.
●30-day ATM implied volatility is 24% — calm pricing; option premium is cheap.

Volatility smile

IV by strike — expiry 2026-09-18. 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.
