What JMBS Looks Like to Options Traders Today

IV rank of 8.2% 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 ($2.8K) means dealers hedge against trend, damping realized volatility and biasing price toward heavy-OI strikes; the 25-delta skew (-0.000) is roughly flat across the wings.
