deep-OTM puts vs calls

What the positioning says

●Call wall at $1,100 (429 contracts), 55% above spot — the upside strike the crowd is already parked on; often acts as near-term resistance.
●Put wall at $700 (462 contracts), 1% below spot — the hedge floor; often acts as support.
●30-day ATM implied volatility is 71% — the market prices very large moves; option premium is expensive.

Volatility smile
