CBOE Volatility Index (VX) Futures
March 26, 2004
The CBOE Volatility Index - more commonly referred to as "VIX" - is an up-to-the-minute market estimate of expected volatility that is calculated by using real-time prices of options on the S&P 500 ® Index listed on the Chicago Board Options Exchange (Symbol: SPX). The VIX Index is calculated using SPX quotes generated during regular trading hours for SPX options. The VIX Index uses SPX options with more than 23 days and less than 37 days to expiration and then weights them to yield a constant, 30-day measure of the expected volatility of the S&P 500 Index.
The contract multiplier for each VX futures contract is $1000.
