deep-OTM puts vs calls

What the positioning says

●Bullish positioning: only 0.66 puts per call outstanding.
●Call wall at $32.5 (2k contracts), 31% above spot — the upside strike the crowd is already parked on; often acts as near-term resistance.
●Put wall at $22.5 (773 contracts), 9% below spot — the hedge floor; often acts as support.
●Deep-OTM call OI is 7.4× deep-OTM put OI — speculative upside positioning dominates the tails.
●30-day ATM implied volatility is 70% — the market prices very large moves; option premium is expensive.
