What CIG Looks Like to Options Traders Today

IV rank of 2.1% is subdued relative to the 1-year history, conditions that typically favor premium-buying or long-volatility structures (debit spreads, calendar spreads, long straddles); positive net gamma exposure ($17.1K) means dealers hedge against trend, damping realized volatility and biasing price toward heavy-OI strikes; the 25-delta skew (-0.170) prices puts richer than calls, the typical equity downside-protection skew.
