What STRO Looks Like to Options Traders Today
IV rank of 23.8% 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 ($3.2K) means dealers hedge against trend, damping realized volatility and biasing price toward heavy-OI strikes; the 25-delta skew (0.177) prices calls richer than puts, often reflecting upside speculation or squeeze risk.
