deep-OTM puts vs calls

What the positioning says

●Bullish positioning: only 0.10 puts per call outstanding.
●Call wall at $45 (170k contracts), 7% above spot — the upside strike the crowd is already parked on; often acts as near-term resistance.
●Put wall at $40 (10k contracts), 5% below spot — the hedge floor; often acts as support.
●Deep-OTM call OI is 7.0× deep-OTM put OI — speculative upside positioning dominates the tails.
●30-day ATM implied volatility is 76% — the market prices very large moves; option premium is expensive.
