交易 Volatility Index - VIX
Price constructed using front two months of Volatility (VIX) Index futures.Each day at 21:59:55 UTC, the price is adjusted to reflect the difference between the front- and back-month futures. At the same time, a matching cash adjustment is applied — ensuring the overall position remains neutral as the roll progresses. This cash adjustment is fully offset by the running profit or loss on the position.
The CBOE Volatility (VIX) Index works as a popular means to find out the expected market’s volatility based on the options of the S&P 500 index. The VIX stock market index is published and calculated by the Chicago Board Options Exchange (CBOE). Colloquially the index is often called the ‘fear index’. Founded in 1986 the current VIX index forms the expectation of stock market volatility for the near future. It quotes the calculated annualised change in the S&P 500 index for the following 30 days.
