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.
The CBOE S&P 500 BuyWrite Index is a passive index involving the purchase of stocks of companies appearing in the S&P 500 (SPX) and the writing of a SPXSM call option. The SPXSM will typically expire in one month and its exercise price is usually above the prevailing price of the index. First published in 2002, the CBOE S&P 500 BuyWrite Index trades under the symbol BXM.
