What DIA Looks Like to Options Traders Today
IV rank of 21.3% is subdued relative to the 1-year history, conditions that typically favor premium-buying or long-volatility structures (debit spreads, calendar spreads, long straddles); the assumed dealer book's GEX is positive ($32.0M of delta per 1% move): its hedging leans against the trend, damping realized volatility where real dealers are positioned like the book; the 25-delta skew (0.030) prices calls richer than puts, often reflecting upside speculation or squeeze risk.
