What the positioning says

●Call wall at $240 (8k contracts), 15% above spot — the upside strike the crowd is already parked on; often acts as near-term resistance.
●Put wall at $200 (8k contracts), 4% below spot — the hedge floor; often acts as support.
●30-day ATM implied volatility is 68% — the market prices very large moves; option premium is expensive.
