A news story by S.L. Mintz on pages S24 and S26 in this weekend’s Barron’s notes that —
“ … Covered call options can protect against a tumble. … Many shareholders want to protect their gains without beating a hasty retreat to cash or bonds. … The CBOE S&P 500 2% OTM BuyWrite Index (BXY) uses S&P 500 covered call options … In the two decades ending on May 31, a dollar invested in the BXY became $6.12, versus $5.35 for … the S&P 500, … These total returns include reinvested dividends but not taxes or transaction costs. Better still, BXY outpaced the S&P with less risk, as indicated by a lower standard deviation.”
The CBOE S&P 500 2% OTM BuyWrite Index (BXY) uses the same methodology as the well-known CBOE S&P 500 BuyWrite Index (BXM), but the BXY Index is calculated using out-of-the-money S&P 500 Index (SPX) call options, rather than at-the-money SPX call options. The BXY Index yields lower monthly premiums than the BXM Index, in return for a greater participation in the monthly upside moves of the S&P 500. www.cboe.com/BXY
