SGU Strategy Selection at Current Volatility Levels
For Star Group, L.P. options at 406.1% ATM IV, high IV rank (82.1%) favors premium-selling structures: credit spreads, iron condors, covered calls, cash-secured puts. The risk: a continued vol expansion through high-rank levels is rare but expensive when it happens. The 25-delta skew is meaningfully put-skewed, so put-credit spreads capture more premium for the same width than call-credit spreads. Pair the vol-rank read with the dealer-gamma view and the upcoming-events calendar to confirm the strategy fits both the structural regime and the path-dependent risk. The variance risk premium - the persistent gap between implied and subsequently realized vol - is positive in equity markets on average; high IV rank typically reflects a stretch where the premium is wider than usual.
