About this indicator
- What it measures
- The 30-day volatility of the S&P 500 index implied by the prices of S&P 500 options, in annualised percentage points.
- How it is calculated
- Calculated by Cboe from a range of S&P 500 option prices; this is the daily closing value.
- How to read it
- Readings around 12-20 are typical of calm markets; above 30 signals fear. A VIX of 20 implies the market is pricing moves of roughly 20 ÷ √12 ≈ 5.8% over a month, about two times in three.
- Caveats
- It is market pricing of expected volatility, including a premium for insurance, not a forecast of direction.
- Frequency
- Daily
- Typical release
- Each trading day after the close.
