About volatility

Volatility indexes measure how much movement options traders are pricing in. The Cboe VIX, derived from S&P 500 options, is the best-known example.

Implied volatility tends to rise into scheduled event risk such as FOMC meetings and CPI releases, and during sell-offs. It often declines once uncertainty is resolved.
