Volatility Skew

Definition

Volatility Skew refers to the pattern that emerges when implied volatility (IV) varies for options across different strike prices or expiration dates. This phenomenon is primarily driven by market participants’ expectations and behavior, particularly their perception of risk regarding potential future price movements of the underlying asset.

Key Characteristics:

Higher implied volatility for out-of-the-money (OTM) puts compared to calls.
Differences in IV that signify market sentiments toward potential price swings.
Fluctuations in IV can be triggered by various market events such as earnings announcements.
