Skew risk refers to the potential for losses arising from an unexpected change in the implied volatility smile or skew of options. The volatility skew reflects how implied volatility differs across options with the same expiration but different strike prices. An unanticipated steepening or flattening of this curve can significantly impact the value of an options portfolio. This risk is distinct from overall volatility level changes.
Measurement
Skew risk is measured by analyzing the shape and dynamics of the implied volatility curve. Traders often use metrics like “skew slope” or “smile curvature” to quantify this risk. A common observation is a “put skew” where out-of-the-money puts have higher implied volatility than out-of-the-money calls, reflecting demand for downside protection. Changes in these metrics indicate shifts in market perception of tail risk.
Management
Managing skew risk involves structuring options portfolios to be robust against adverse changes in the volatility smile. This can include trading volatility spreads, using options with different strikes and expirations, or dynamically adjusting positions as the skew evolves. Traders often seek to be “long skew” if they anticipate a steepening, or “short skew” if they expect a flattening. Effective management is crucial for complex options strategies.
