The VIX
The VIX (CBOE Volatility Index) is a measure of the implied volatility of the S&P 500 index. It is calculated using the prices of options on the S&P 500 index that are traded on the Chicago Board Options Exchange (CBOE).
The VIX is calculated using a complex formula that takes into account the prices of a wide range of options with different strike prices and expiration dates. The formula uses a weighted average of the implied volatilities of a wide range of S&P 500 options, which reflects the market's expectation of volatility in the future.
In summary, the VIX is calculated using the implied volatilities of S&P 500 index options, which are derived from the prices of those options, to estimate the expected volatility of the S&P 500 over the next 30 days. It is often referred as the "Fear Index" because it tends to spike when investors are worried about market volatility.
