TETH Strategy Selection at Current Volatility Levels

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.
