The VIX index was created by the Chicago Board Options Exchange in 1990
to measure the future volatility of S&P 500 index options. The VIX index is a real-time data
that reflects the market's expectations of the degree of volatility in the next 30 days.
The VIX index is calculated based on weekly and traditional SPX index
option prices and their implied volatility levels. The calculation method is very
complicated. Since the VIX index can be used to measure market sentiment, the market also
calls it the panic index.
The VIX index tends to rise in a bear market environment, but tends to
fall or remain stable in a bull market. This is because the VIX index is calculated based on
implied volatility, which is low in the long-term bullish stock market.
At present, the VIX panic index (VIX) provided by Prospero Global is
quoted with reference to the index futures contract of the most recent month. Currently,
this product is set as read-only and cannot be used for trading.
