A commonly followed index is the VIX, a daily index compiled and published by the Chicago Board of Options Exchange (CBOE). The VIX is an index that is composed by measuring the implied volatility that is implicit in the prices of equity options traded on the exchange. A high level of the VIX implied that investors are uncertain of the future direction of price changes.5Chicago Board of Options Exchange
