Historical Volatility Skew

Historical volatility skew describes the tendency for the implied volatility of options to differ across various strike prices, often reflecting market participants' expectations of future price movements. In the context of derivatives, this skew is a crucial indicator of market sentiment and the perceived probability of tail events.

A steep skew often indicates that the market is paying a premium for downside protection, suggesting a fear of a market crash. Conversely, a flat skew might indicate a period of relative calm and indifference.

By analyzing this skew, traders can infer the market's collective view on potential volatility and risk. It is a fundamental component of quantitative finance and the pricing of options.

Understanding why the skew exists helps traders identify mispriced options and develop hedging strategies that account for market fears. It is an essential tool for evaluating the risk environment in both traditional and digital asset markets.

Monitoring changes in the skew over time provides a lens into shifting market expectations.
