BLLN Strategy Selection at Current Volatility Levels
For BillionToOne, Inc. options at 81.5% ATM IV, mid-range IV rank 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. 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.
