Live CBOE Volatility Index level, refreshed every 15 seconds during market data availability.
The VIX is calculated from the prices of S&P 500 index options, reflecting the market's implied expectation of volatility over the coming month.
It typically sits in a low range during calm markets and spikes sharply during periods of stress, making sudden VIX increases a common early signal of rising uncertainty.
FAQ
What does the VIX measure?
The VIX estimates the market's expectation of S&P 500 volatility over the next 30 days, derived from S&P 500 index option prices.
Why is it called the 'fear gauge'?
VIX tends to spike sharply during market stress and selloffs, since demand for protective options rises — making it a widely watched proxy for investor anxiety.
