FAQPage Schema
What is option volatility skew and how does it indicate directional risk?

Option volatility skew measures how implied volatility (IV) varies across strike prices, revealing directional fear and tail risk. Traders analyze the smile shape to understand market sentiment and whether puts or calls carry higher premium demand.

How do I analyze the volatility smile for a specific ticker and expiration date?

To analyze the volatility smile, provide a ticker symbol and an optional expiry date. The tool returns the smile curve plotting IVs across strikes, skew metrics, and a shape classification for trading insights.

What does a 25-delta risk reversal tell me about option skew pricing?

A 25-delta risk reversal quantifies directional skew by measuring the IV difference between out-of-the-money puts and calls. It indicates whether traders are pricing in more downside or upside tail risk for that expiration.

How is volatility smile shape classified into normal, smirk, or reverse patterns?

Volatility smile shape is classified as normal, flat, reverse, winged, or smirk based on the IV distribution curve across strikes. This classification helps identify skew pricing patterns and tail risk dynamics.

Can I interpret current option skew versus historical percentiles for trading ideas?

Yes, the analysis provides percentile rankings of current skew against historical data. This offers actionable insights by showing whether existing directional fear and skew pricing are elevated or depressed relative to recent trends.

Does the volatility smile analysis work without specifying an expiration date?

Yes, you can analyze the volatility smile by providing just a ticker symbol, as the expiry date is optional. The tool will return the smile curve, skew metrics, and shape classification for a single expiration.
