Cboe S&P 500 Conditional BuyWrite Index (BXMC) www.cboe.com/BXMC

The Cboe S&P 500 Conditional BuyWrite Index is designed to track the performance of a hypothetical covered call strategy that holds a long position indexed to the S&P 500 Index and sells a monthly at-the-money (ATM) S&P 500 Index (SPX) call option. The written number of ATM call options will be either ½ unit or 1 unit and will be determined by the level of the Cboe Volatility Index (VIX Index) when the call option is written on the Roll Date.

The BXMC Index rolls on a monthly basis, typically every third Friday of the month.
