About CBOE Volatility Index
The VIX, often called the 'fear gauge', measures the market's expectation of 30-day forward-looking volatility implied from S&P 500 options prices. It is not a traditional stock index but rather a real-time sentiment indicator used by traders to gauge market fear and complacency.
