What NBBK Looks Like to Options Traders Today
IV rank of 41.1% 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 ($26.2K) means dealers hedge against trend, damping realized volatility and biasing price toward heavy-OI strikes; the 25-delta skew (-0.030) prices puts richer than calls, the typical equity downside-protection skew.
