What IOO Looks Like to Options Traders Today
IV rank of 1.7% is subdued relative to the 1-year history, conditions that typically favor premium-buying or long-volatility structures (debit spreads, calendar spreads, long straddles); negative net gamma exposure (-$2.1K) means dealers hedge with trend, amplifying realized volatility and accelerating directional moves; the 25-delta skew (0.022) prices calls richer than puts, often reflecting upside speculation or squeeze risk.
