Put and Call Selling

Simultaneously selling puts and calls is also very profitable.

Note that average monthly return for -.5/-.5% straddle = 2.8% = 48% of the maximum (gross) profit of 5.7%.

Note that -5.6/+4.6% strangle maximum loss = -20.6%.

Note that the at-the-money combinations are most profitable, but that your percent profitability (88%) is lower. As you move further from at-the-money, your percent profitability approaches 100%, but your rate of return drops. The intriguing combination of a 10.7% out-of-the-money put sold and a 15.6% out-of-the-money call sold simultaneously leads to a 12.1% return, about equal to that of the stock market, but with only a sliver of the risk. Caveat: cash returns are included, which may be significantly lower in a low interest rate environment.

Leverage: Combining leverage plus out-of-the-money option sales leads to a nice trade-off between reliability and profitability:

In other words, with the OEX at about 570, if you had a $76,000 portfolio and simultaneously sold 2 calls 4.6% out-of-the-money and 2 puts 5.6% out-of-the-money, you could replicate this amount of leverage. This portfolio would throw off an expected $28,804 worth of income a year in collected premiums net of market losses. Note that the 10th percentile is a very respectable 1.0%, meaning that 90% of the time your monthly return was 1.0% or higher.
