PSX Strategy Selection at Current Volatility Levels

For Phillips 66 options at 34.2% ATM IV, mid-range IV rank (48.2%) is the regime where directional conviction matters more than vol-regime positioning; strategy choice should follow the event calendar and the dealer-positioning view rather than IV rank alone. 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.
