What SEM Looks Like to Options Traders Today
IV rank of 45.3% sits near the 1-year median, where strategy choice depends on directional conviction and the event calendar rather than vol regime alone; negative net gamma exposure (-$26.2K) means dealers hedge with trend, amplifying realized volatility and accelerating directional moves; the 25-delta skew (0.153) prices calls richer than puts, often reflecting upside speculation or squeeze risk.
