弱弱问句：何为VIX指数？

VIX - CBOE Volatility IndexWhat Does VIX - CBOE Volatility Index Mean?
The ticker symbol for the Chicago Board Options Exchange (CBOE) Volatility Index, which shows the market's expectation of 30-day volatility. It is constructed using the implied volatilities of a wide range of S&P 500 index options. This volatility is meant to be forward looking and is calculated from both calls and puts. The VIX is a widely used measure of market risk and is often referred to as the "investor fear gauge".

There are three variations of volatility indexes: the VIX tracks the S&P 500, the VXN tracks the Nasdaq 100 and the VXD tracks the Dow Jones Industrial Average.
