What MASI Looks Like to Options Traders Today

IV rank of 37.2% 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 ($73.4M) means dealers hedge against trend, damping realized volatility and biasing price toward heavy-OI strikes; the 25-delta skew (0.009) is roughly flat across the wings.
