Chart description
Skew is the relative richness of put vs call options, expressed in terms of Implied Volatility (IV). For options with a specific expiry, 25 Delta Skew refers to puts with a delta of -25% and calls with a delta of 25% to demonstrate this difference in the market’s perception of implied volatility. 25 Delta Skew is calculated as the difference between a 25-delta put’s implied volatility and a 25-delta call’s implied volatility, normalized by the ATM Implied Volatility. The individual periods refer to option contracts expiring 1 week, 1 month, 3 months, and 6 months from now, respectively.
