"Pension executives are once again beginning to consider a long-standing but long-dormant derivatives strategy - covered call writing, or buy writing - to hedge their downside equity risk and add incremental alpha... While options industry executives said the strategy is not new, two developments have given it more credibility. First, in 2002, the Chicago Board Options Exchange created a buy-write index based on the S&P 500, the CBOE S&P 500 BuyWrite Index, or BXM... Second, and possible more important for institutional investors, Ibbotson Associates, Chicago, released a report..."

Covered S&P 500 Index call strategies have, on average, outperformed the S&P 500 Index over the past 15+ years while realizing lower standard deviations of returns. This analysis dissects the strategy underlying the BXM Index, the most broadly quoted benchmark for index call-selling strategies. Also discussed are alternative structured S&P 500 option-overwriting strategies, which have even more attractive risk-return trade-offs than the BXM because they take advantage of the implicit positive risk premium of equities and potentially adjust the strike price of the call sold on the basis of the volatility environment.

The BXM, BXD, BXN, BXY, CLL and PUT indices (the "Indexes") are designed to represent proposed hypothetical options strategies. The actual performance of investment vehicles such as mutual funds or managed accounts can have significant differences from the performance of the Indexes. Investors attempting to replicate the Indexes should discuss with their advisors possible timing and liquidity issues. Like many passive benchmarks, the Indexes do not take into account significant factors such as transaction costs and taxes. Transaction costs and taxes for strategies such as the Indexes could be significantly higher than transaction costs for a passive strategy of buying-and-holding stocks. Investors should consult their tax advisor as to how taxes affect the outcome of contemplated options transactions. Past performance does not guarantee future results. This web page contains index performance data based on back-testing, i.e., calculations of how the index might have performed prior to launch. Backtested performance information is purely hypothetical and is provided in this web page solely for informational purposes. Back-tested performance does not represent actual performance and should not be interpreted as an indication of actual performance. It is not possible to invest directly in an index. CBOE calculates and disseminates the Indexes. Supporting documentation for any claims, comparisons, statistics or other technical data is available from CBOE upon request. The methodologies of the Indexes are the property of Chicago Board Options Exchange, Incorporated (CBOE).
