VIX

The VIX, or Cboe Volatility Index, is a real-time market index that represents the market's expectation of 30-day forward-looking volatility, calculated from the weighted prices of out-of-the-money put and call options on the S&P 500 Index (SPX). Often referred to as the "fear gauge," the VIX is a crucial benchmark for global financial market risk, providing a quantitative measure of investor sentiment and uncertainty.
