What PTGX Looks Like to Options Traders Today

IV rank of 3.7% 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 ($49.4K) means dealers hedge against trend, damping realized volatility and biasing price toward heavy-OI strikes; the 25-delta skew (0.047) prices calls richer than puts, often reflecting upside speculation or squeeze risk.
