What MDYG Looks Like to Options Traders Today

IV rank of 33.2% sits near the 1-year median, where strategy choice depends on directional conviction and the event calendar rather than vol regime alone; positive net gamma exposure ($5.6K) means dealers hedge against trend, damping realized volatility and biasing price toward heavy-OI strikes; the 25-delta skew (0.022) prices calls richer than puts, often reflecting upside speculation or squeeze risk.
