Explanation
The CBOE S&P 500 BuyWrite Index (BXM) is designed to mimic the performance of a buy-write strategy applied to the S&P 500. Also referred to as a covered call, a buy-write is a strategy in which the investor purchases a portfolio of stocks (in this case the S&P 500) and also sells call options on the same "basket" of stocks. Buy-writes typically underperform stocks when their prices increase, and outperform stocks when their prices decline.
