The risk: low-rank regimes can persist for months while time decay eats premium-buyers alive. The 25-delta skew tilts to calls, so call-credit spreads or covered-call writes harvest more premium than put-credit spreads of the same width. 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.
