About CBOE Volatility Index
The CBOE Volatility Index, widely known as the "Fear Gauge," measures the market's expectation of near-term volatility based on S&P 500 option prices. Unlike stock indices, the VIX tracks investor sentiment and typically rises during periods of market uncertainty and financial stress.
