The CBOE Volatility Index (VIX), often called the “fear gauge,” is a real-time market index representing the market’s expectation of near-term volatility (typically the next 30 days) for the U.S. stock market. It is calculated using the prices of S&P 500 Index (SPX) options and reflects investor sentiment—higher VIX values indicate greater perceived market risk or fear, while lower values suggest calm or complacency.
Key Features:
- Calculation Basis:
- Derived from the weighted average of prices for SPX call and put options across a range of strike prices.
- Represents an annualized volatility percentage (e.g., a VIX value of 20 implies an expected 20% annualized volatility for the SPX over the next 30 days).
- Market Significance:
- Widely used by traders, investors, and institutions to gauge market stress.
- Historically spikes during market downturns (e.g., the 2008 financial crisis, COVID-19 pandemic) and declines during bull markets.
